For my school project I have to realize a mini website where I use primefaces framework. In a form I want after pressing the Save button two things: 1 - Validate the data entered. that's why I put

As the values are not correct, the dialog box should not be displayed. 2 - When all data is correct, and I click Save, I want to display my dialog box.

I want my application to be distributable as a single .exe file but I want to be able to get nice error reports with source code line numbers (the application simply sends email with exception.ToString() and some additional information when unhandled exception occurs).

I am a new in C sharp and a little stupid, I have a problem with my project, hope you can help me!

Now I want to transfer data from this text box into an existed 2d Matrix that will store data in Integer Type.

You're wrong about what's causing that error. On windows *.exe has stopped working. generally means that your application has segmentation faulted.

This can be caused by any read or write out of the memory bounds, which generally means you messed up with a free()/delete, a malloc()/new, or a NULL somewhere, but with more code, or without further explanation, I cannot diagnose further.

I have a large bit stream. (e.g. 10110001010101000.....001 size thousands or millions)

If you want to return two values, return a std::vector with them. Maybe a std::pair, or a class. As far as why, this is just how C++ works. Comma is just an operator, like + or -. It discards its left operand and returns the right one. return returns the value of its expression from the function. The rest you can figure out yourself.

and you need to make sure to register the event in the GridView OnRowCommand="cgvProjectPropertyList_RowCommand"

I have a website working fine in all browsers except IE. When I look at the console it says:

It's my very simple client-server application. Client sends some commands to the server and server gives back the output to the client. However, my special concern is about the GET command sent to the server. The client request GET filename to download a named file. That file ultimately gets downloaded into the client directory with the HTTP response headers, as I have designed my protocol.

Now I am afraid if my coding follows the protocol accurately. Especially the HTTP response headers with the Line break (in both client and server side).

I am trying to combine two tab seperated text files but one of the fields is being truncated by awk when I use the command (pls suggest something other than awk if it is easier to do so)

but I only print 10203853138 for $4 truncating the other digits. Should I use string format? Actually I found out after a suggestion given that pr -m -t itself does not give the correct output

Regarding the blank-page issue: You're just processing, not outputting anything. You could simply post a redirect-header at the end - possibly according to errors occuring or not.

..or just output stuff after processing. A good practice might be to keep processing and the form-display in one file - then you could pre-populate the form with the fields that did not produce errors and mark those that failed so the user can try again.

If the possible duplicate doesn't fulfil your needs here's a way to do it - Plunker.

so you should (in theory) be able to rely on the last repeat element being created last.

In your local copy of the repo, edit progressbar/__init__.py and change the following line:

Save the file, then reinstall with pip. Of course, without a pull request, this will only work locally for you.

Another option is to use the much more up-to-date progressbar2, on Github here. It has been validated to work up to Python 3.5. Obviously, you'll have to test your code to ensure it works with the new version, but this is probably your best bet.

I'm trying to do a fairly simple load function with Jquery (at least I think it is), but it simply isn't loading anything.

I'm sure it's something obvious, but I simply can't find it. I appreciate any help. Thanks

I'm new to JSF and in the process of learning im building an online book store application.

I have 1 class and 1 bean: Book.java and BookCatelogBean.java. The Book class has 3 properties: id, title, and author with it's corresponding getters and setters. The BookCatelogBean contains an ArrayList<Book> where I populate it with Books (in future I will connect it to a database).

I have two pages: index.xhtml and book.xhtml. I want to display the list of book titles on index.xhtml each formatted as a REST link and their ID to book.xhtml, like so: <h:link outcome="book?id=#{bookCatelogBean.id}" value="#{bookCatelogBean.title}" />

I know how to use BookCatelogBean to display 1 book but I want to display all of them? I have an idea to call a method from BookCatelogBean called getAllBooks() that returns each of the books titles but how would I return each one of them to index.xhtml as a JavaserverFace link instead of a string?

Perhaps your regexps don't match your group names? The above regexps will match groups that look like mail. and gmane. (the . being a real period).

The way I tested it was to enter each of the two groups and did an eval on the variable M-: gnus-use-adaptive-scoring RET - though you could also just do help on the variable C-h v gnus-use-adaptive-scoring RET.

Perhaps what you want is not to turn adaptive-scoring off, but just to turn scoring off. AFAIK, adaptive-scoring is Gnus trying to figure out scoring for the articles, but not the actual use of scoring.

If you have the relevant permissions within Management Studio, this shouldn't take too long to work out. It sounds like the bad-user AD group has limited permissions within SQL Server.

You need to check the settings in Security in the GUI, and check the mappings for each of these AD groups - clicking on the databases to see what permissions they have on each database.

Using Javascript, specifically Google Apps Script (GAS), I need to convert an .xls file to JSON; but I would settle for .csv or .xml.

Does anyone know any way to do this? Some library, perhaps? Or a private script willing to share? (Note: GAS can not recognize ActiveXObject)

Prior research (does not apply)

This question does not apply because I am asking for a solution coded in Javascript (or a workaround for Google Apps Script). (The answers to the above question focus on a Java solution and other various .csv to JSON converters.)

Yes, I know there is an open issue for GAS already in the works. But I was wondering if anyone has coded any .js workaround to do the job in the meantime?

There is no such thing as a line in the DOM. But you can scroll to a element. There is a really nice jQuery extension that does it scrollTo.

But to make a bookmark could be a bit messy. Because you need both jQuery and this plugin.

It doesn't violate IEEE-754, because IEEE-754 defers to languages on this point:

In standard C, the STDC FP_CONTRACT pragma provides the means to control this value-changing optimization. So GCC is licensed to perform the fusion by default, so long as it allows you to disable the optimization by setting STDC FP_CONTRACT OFF. Not supporting that means not adhering to the C standard.

What is going on here? How do I convert 0.47000000000000003 to string and the resultant value back to float?

I don't need code, just a starting point. I have a drawing app on iPad where you draw a line from point a to point b. Between the 2 points the line is replaced with a repeating image.!

How about just causing an exception by hand, i.e. raise(SomeMeaningfulException)? That should get handled automatically by the errormiddleware.

I have developed a custom kind of combo box that uses a grid instead of the standard combo picker (mainly to benefit from buffered rendering with huge data sets). I am now trying to make it compatible with Ext 4.2.1 but I ran into this error:

Please, see the demo pages for test cases. The error is raised once for each combo, but only the first time it is expanded.

This error didn't happen with 4.2.0 (see demo page with 4.2.0). The breaking changes I had identified in 4.2.1 at the time were about the query filter, not rendering or layout... However, I have already been facing this error with 4.2.0 in a situation where the grid picker was sitting in a window, but it was in a code base with lots of overrides and that used the sandboxed version of Ext4... So I just hopped it was not coming from my component and silenced it (another demo page proves that grid picker + window is not enough to trigger the error).

Does anyone know what is causing that or, even better, what must be done to prevent it?

Or does someone understand Ext's layout engine well enough to give me some pieces of advice on how to track down this kind of error? Or at least give me reassurance that the error will remain harmless in any situation?

the main source, "_opg" is a List>. Basically as "op" is a DateTime type, I would order this new object by "op" in ascending way. Any hints?

I am trying to make a pairing by code and it works only for normal devices. If I use a bluetooth scanner it pairs with it but the device doesn't work till I go to android settings and select the Input Device checkbox. How can I do this by code?

Something like this should give u all the filenames in the folder, for you to manipulate:

I would like to create a method for an array that checks if the 'id' field within the object does not already exist in the array. If not, then 'push' object into the array, else do nothing.

I would like the function to take the 'id' field as an argument so this function has wider use.

Are there any drawbacks to extending the array.Prototype? Otherwise I can do a for loop instead to do the check without the prototype constructor.

This DELETE all the records from the table abc with JOIN to another table. It deletes all the records in the table abc that has a RECORD_TYPE value equal to the RECORD_TYPE in the other table AND in the same time the value IN are equals in the two table.

It is a normal DELETE clause, Where the FROM can contain extra joined table as specified by the documentation:

set fix width in File Uploader as: style="width:300px". This will not distort the design and will restrict the filename within the given width limit

I have VSCode vs. 1.3. and I would like to be able to click in any valid path showed inside the integrated Terminal and get the file opened.

The solution to your problem greatly depends on your code. You should definitively include the relevant code bits in your SO questions if you want to get help.

I'm going to make a guess and assume that your code looks similar to the MapView example:

What you want is that code executed earlier. Ideally, when the application starts. The user will get the "this application wants access to the GPS" message right away, so they will have more time to "approve" before seeing the mapview.

Another thing you can do is using a cache. Store the latest known location somewhere (a config file or the database, depending on your setup). When the connection is lost, or not yet retrieved, show the last known location on the map.

The way I solved this problem for my app was to define the colors in values/color.xml.

This gives me a Color object directly without worrying about getting the color from a Drawable.

to the html head section. Then - which was not so clear for me either - the main.js script needs to be added after the button. I didn't reference the file (which isn't in the package as far as I could tell), but included the script directly - this way:

Hope this helps somebody (more than one year on I gues you have either solved it or moved on!!)

I am writing a JUnit test for code submitted to a competition. The rules of the competition require that certain methods not be called from other methods. (I unfortunately can not change the rules.)

The contestants are all implementing an interface we supplied which includes an add(K key, V value) method and a delete(K key) method. We need to test that entries do not implement delete by adding every other element to a new object and return that object.

We are also trying to avoid adding dependencies outside of the Java core since we are using a lot of automated tools (like the Marmoset Project) to test the hundreds of submissions.

I read through the documentation for Java Reflection and Instrumentation and nothing jumped out at me.

I'm new to R and I've compiled it myself on Ubuntu 14.04.3 (x64). Note, I am up to date with the R source:

Running configure and make in R's 3.2.2 branch have completed successfully and I'm able to use a variety of packages within an R session. However, I'd like to check that all of my libraries are up to date. In R 3.2.2 , I'm invoking update.packages(). When the function is invoked, I'm prompted to select a CRAN mirror :

Assuming everything is fine and this is a non-issue, I select the main ("O-Cloud [https]") mirror from the dialog. The dialog closes and I'm returned to my R prompt with a duplicate message saying "unsupported URL scheme".

Simultaneously, I receive an error in my R session upon invoking update.packages():

Considering that perhaps this is an issue with HTTPS, I try a non-SSL mirror and similarly nothing happens (perhaps there are no updates, but I'd like a message that tells me this). However, this time I don't receive the second "unsupported URL scheme" message after the dialog closes :

It seems that under the hood, R uses a library called RCurl to do some of it's HTTP/S interaction. As far as I can tell, I'm using a supported version of curl / libcurl :

Any thoughts on this? It seems similar to this mailing list discussion, but I'm not sure if this is an issue or I'm doing something wrong.

In a Terminal window type man ld and you'll get a description of the ld command and the arguments it takes. There you'll find -F specifies a directory to search for frameworks in. The Xcode generated command line contains:

The second entry is actually redundant - it is the same as the third (as .. means parent) - but it looks like your problem is the way the path is escaped. To allow a space in a path you can either enclose it in quotes or precede the space with a backslash. Paths 1 & 3 use the backslash method, path 2 uses both and so the backslash is presumably treated as a literal character (that is what would happen in Terminal) and therefore the path is incorrect... (cross-eyed yet? ;-))

Maybe this double-escaping was introduced when the project was converted to Xcode 5. The paths are listed in your project's settings (sorry Xcode not to hand), hunt it out and remove it (as its a duplicate).

All .NET code is converted to an intermediary language that is executed, thus all .NET languages can be used to write a windows service.

I have a Django project that interfaces with a PostgreSQL database; one of my tables is about 450 rows long and each row contains about a dozen columns.

Each column's value must be put into a different formula to produce the final data I want to display in the template layer, but each row will be processed with the same set of calculations. (In other words, I want to perform 12 different calculations 450 times each.)

My question is, of the following methods, which is the generally accepted method of doing so, and which is the best in terms of performance:

A) Write each calculation as a model method in models.py, query all objects of interest (again, about 450 of them) in views.py and pass them directly to the template, and then use Django's template language to write things like:

B) Peform the query and calculations in the views.py file and pass the results organized into one big dictionary or list or JSON to the template (and then parse it using template tags),

C) Pass all of the objects of interest to the template as in A), but perform calculations on each object's fields using Javascript or jQuery,

D) Combine B) and C) to perform all database queries in views.py and then pass the raw values as a big dictionary/list/JSON object to the template and perform calculations on those values using Javascript/jQuery.

To my mind, method A) seems the least efficient as it requires you to hit the database a ton of times in the template layer. But it makes writing the view and template extremely simple (just requires you to write 12 different model methods). Method B) seems to follow the general tenet of performing as much logic as possible in your view, and simply passing along the final results to be displayed in the template. But it makes the view function long and ugly. Methods C) and D) put most of load on the end user's browser, which seems like it could really take a load off the server, but then obviously won't work if the user has JS turned off.

But again, I'd like to know if there's an accepted best practice for this kind of situation, and whether that contradicts the fastest method from a computational standpoint.

And obviously, if I've missed the best method of all, please let me know what it would be.

I am tring to get the mean of three vectors but the mean function is not working.

Why not just make evey different view a different site, ie give the ads in each view a different id. It is a little bit of a pain to set this up if you have several applications/or lots of views, but I think that it should work.

In terms of generic things to know I suggest you read a book, so you get one consistent message explaining all the basics.

Finally check out the hackety-hack project it's designed to help people learn to program, although version 1 is only just out. http://hackety-hack.com/

The first group could be prefixed by QA or DEV , use the | or operator.

You can configure IntelliJ to use a lot of different application containers, but each of them must be downloaded and installed separately. I currently have mine configured to serve via jetty, like eclipse, and also tomcat, tc-server, jboss, and node.js. It's pretty easy to set up.

The full method is pasted below. When calling JTable::getInstance you must pass $type as an argument. The getInstance method then uses $type to define $tableClass as you can see below.

The method then proceeds to load (import) the class if it's not already and then finally calls return new $tableClass($db);

So if you search for TableK2Item you should indeed find that class which has a hit() method.

You can't actually modify/save the image in javascript/jquery (as far as i know). You'll have to use server-side image manipulation libraries like gdlib (http://www.boutell.com/gd/) which is usually activated by default in php, or imagemagick (http://www.imagemagick.org/script/index.php)

My favorite method is to add a text-align: center; to the parent element, then use display: inline-block; instead of float: left;

If you want to save modified source as html you can use different aproaches, depends on what you want to mainupulate. Sadly with javascript saveing file is tricky and depends on many things, so you could use option to copy paste file source manually or write your browser and settings specific file saver. I would prefer javascript+php combo solution. Or if there is no need to manipulate someting with javascript i would do it entirely in php.

Step 1 - open browser with console, in chrome and firefox CTRL+SHIFT+J And allow popups. Step 2 - open webpage you want Step 3 - Copy next code to console

If you want to do it with PHP you can easily download page with curl and manipulate content and save file as desired.

For the integration of these two libraries together I have followed this link here. Also I have used the Otto 2.0-wip lib that is suggested there and not that from Otto Git.

I declare an object for this class inside my Fragment Class where I want to subscribe at events :

I post event to the bus from my communicator class when it gets callback from server communication. This is how I post event to my bus inside this class:

Problem: My problem is that my method which is subscribed at bus event onChangeUserDetailsEvent doesnt get called and I dont even know how to debug to fix this problem.

I should mention that bus event works perfectly when I implement it in a Fragment that doesn't use Annotations, and a Bus singleton without Annotation. This is the Bus singleton class when I don't use Annotations:

I also have a problem when I update to androidannotations:3.2 changing my gradle file from:

compile 'org.androidannotations:androidannotations:3.1' apt 'org.androidannotations:androidannotations:3.1'

compile 'org.androidannotations:androidannotations:3.2' apt 'org.androidannotations:androidannotations:3.2'.

For version 3.1 it compiles but doesnt work otto event bus. With version 3.2 it gives error.This means that AA library has made some changes that I need to implement or it has bugs. How can I find the solution ?

This is one of the errors(for demonstration): Error:(27, 25) error: cannot find symbol class UserAccountActivity_ which is a class that is activity.

Pointers do not keep information whether they point to single objects or for example first elements of arrays.

Thus you have to provide yourself the information about whether a pointer points to an element of an array.

You can do this in two ways. The first one is to specify the number of elements in the sequence the first element of which is pointed to by the pointer. Or the sequence must to have a sentinel value as strings have.

The same way an array of strings can be printed. Either you will report explicitly the number of elements in the array yourself. Or you can use a sentinel value as for example a null pointer or an empty string.

Hey guys so I am trying to have a JSON send over a value to another page in wordpress to create a session once a image is clicked on.

The #hiddenposttitle is the following: <?php echo "<input type='hidden' value='$title' id='hiddenpostitle' name='hiddenpostitle'/> "?>

So this sends to the overviewcheck page, which then has a template that has the follow:

Someone mentioned something about wordpress destroying sessions from calling session_start() but that's not the issue because I fixed that awhile ago, and have other sessions being made that work. It has to do something with the JSOn sending over and I am not to sure.

Ultimately I am unable to echo out a session and it does not seem anything is being made.

User will have a control to change the background and text (multiples) by doing horizontal swipe for BG and vertical swipe for text. In this case, if I am changing BG, text should remain constant and if I am changing text then BG should remain constant.

Also, I want to add Rubber Band effect like in iOS when user changes Text and BG.

I am thinking of twoway-view library to support for vertical and horizontal scrolling. But how to use this library in my case?

look at the encoding of youre text file. Should be utf8. If not this could cause problems.

secondly, make sure the column datatype is nvarchar and not varchar. Also see here

I'm decode JSON like that and show it but how to search in this api url i don't know.

I'm new to jQuery Mobile and I've been trying so hard (been googling for 2 days straight) to understand how the navigation to external pages works but finding it really hard so hopefully I can get a proper explanation here. From my searches I've found the $.mobile.navigate function but I haven't quite figured out how exactly to use it.

Basically what I have is a login.php page, after you successfully logged in you should be taken to the homepage.php, I've managed to make it so that the homepage.php's content is shown, but when it comes to the URL I can see for a split second that it changes to homepage.php but immidiately changes back to login.php. How can I make it so that it stays on homepage.php?

I read somewhere that data-url is used for changing the url on navigation but I haven't been able to make any use of it from my attempts.

if a customer has a valid warranty status the price of selective product will be free. So I try bellow code and I'm sucked at how to get all $target_products price & set their new value . I'm not sure which hook will work fine.

I have a jQuery cycle slider working fine, but the pager I need split into different places. The paging itself works, but the active slide is the same for each div - i.e. for the first slide, the first pager in each div will show as active. I'm having a hard figuring out how to solve this problem!

Your code works fine for me. What error you might be having is in processFile function you are creating a file object from the fileName, which is not existing. Then might be trying to read the contents of the file which might be throwing you FileNotFoundException. just comment processFile function and your code will work.

Hi guys, I'm working on a Java rich client and I encountered the above symptom. When the JComboBox is clicked for the first time, a null pointer exception will be thrown by the code and then, when I try clicking on the JComboxBox again, actionPerformed() is not triggered.

One activity contains one fragment and this fragment contains one RecyclerView. RecyclerView item contains two textviews which displays simple text like this :

If User taps on text value, its value gets changed (Value is binary so it will be only two). If user change first two item's value by tapping and I want to restore those two values when I will come back to this fragment with a help of restore/save state.

I followed many articles and gather information that if I have to use proper unique id in item's view layout for both textviews then recyclerview state will be stored automatically, only just you need to save whole recyclerview state. Its not working in my case. What am I doing wrong? Do I need to fill adapter again?

In my asp.net forms app. I'm trying to prevent caching of certain pages. to do so I've set a series of cache control headers using Response.AppendHeader e.g.

Trouble is when I view my site and look at the Net tab in the Firefox console to view the request/response headers I see a behavior as follows:

That second request seems to allow the caching to happen for the page.. note: page1.aspx and page2.aspx both have the OnLoad logic I describe above. Also if I take some action on page2.aspx, the POST response will again have the correct headers.

What am I missing here? My expectation was that with the logic in OnLoad should mean that I always get the headers in the response and therefore 'always' get the current version of the page?

I'm considering creating a random identifier in the request url to force the matter, but that seems a little heavy handed.

-----update----- It seems that, this may be related to having the caching code in 'OnLoad'. I've added these headers to the Page_Load() of the page and it works fine? any thoughts.

Let's say I have two buttons in Activity1 (save and cancel). I name them (IDs) as btnSave and btnCancel. Now I have Activity2, where in I have save and cancel buttons as well. Both does the same functionality. What will happen if I give the IDs as btnSave and btnCancel.

Will i face a problem while compiling? When I press, R.id. and ctrl+space, will I get two btnSave and btnCancel(s) to choose from?

Before everything sorry for my english, i am italian, and italians are not so good with other langs... Anyway, here's my actual code:

Well, as you can see it prints out date(italian date order, so GG-MM-YYYY) and hour:mins:secs. Is there something like now->tm_millisecond? Or it's more complicated? As you can imagine i don't want the current date in millinseconds(millisecons passed till years 0) as almost everyone wants. I just want to get the elapsed time in MSs from the last beginning of a second. I am a beginner in c++, the basic code's took around the web. I just wan't the satisfaction to get itfinished. PLEASE DO NOT TELL ME TO MAKE BETTER THIS, TO MAKE BETTER THAT, TO USE A NEW WAY TO CLEAR SCREEN INSTEAD OF system("cls") RESPOND TO WHAT I ASKED.

However, it was never really answered in the way that I needed it. So I thought I would ask.

I have a table A (tableA) and this table has a load of states in tableB. New states keep being added all the time.

TableB has a column 'State' which has a foreign key to TableA.Id. This table B has a value and timestamp

I am trying to get ONE query which will bring back ALL values in TableA, with an inner join to bring the LATEST 'value' of those rows from tableB. The latest being the one with the latest time.

I know how to do an inner join where it needs to be, and I know how to order a table to bring back the latest 'time' row, however I dont know how to put these two together and create a single query.

I'm sure I will have to have a Select within a select, which is fine. However, what I am trying to avoid is to bring a DataTable back with all my results from TableA and do a query for each of those on tableB seperately.

EDIT - I have made a mistake with the question, I only really noticed when trying to implement one of the answers.

I want to bring back all values of TableA with a join on B, to bring back the 'State' of the Max time

I'm working on a site that hosts a lot of PDF files and I want to open them in fancybox (2.1) for a preview. It works just fine in Chrome and Firefox. But it just won't work in IE8. I've tried linking directly to the PDF file, linking to an iframe, and linking to an embed tag (among other crazier things). I can't use google to wrap them. Here is a page that demonstrates the problem.

The results are different each time. In IE for the first link the spinner appears and hangs. For the second two, a fancybox popup appears, but it's empty. What am I doing wrong?

Well it passes to the Post function and adds all information to database and in the same time it show the same error I wrote before.

Handling the TextChanged event should work, however you need to set the DropDownStyle to DropDownList so that the Text property can only be a given value. Then check to see that both comboboxes have values selected. something like this should work:

If ComboBox_Ticker.Text <> "" AndAlso DateTime.TryParse(ComboBox_Date.Text, Nothing) Then

I am trying to add several CALayers to an NSView but my view remains empty when shown:

I am not really sure what you mean by integrating bootstrap with Meanjs, according to me it is already integrated in the default app. If you go to config/assets/default.js and config/assets/production.js (one is for development and the other for production) under client.lib.css and client.lib.js the bootstrap modules are specified. These modules are loaded in modules/core/server/views/layout.server.view.html just under the comments  and  when the application starts.

If you want to upgrade to the latest Bootstrap just change the version number in your bower.json file and run the command bower update.

If I am making changes to already written T-SQL, then I follow the already used convention (if there is one).

If I am writing from scratch or there is no convention, then I tend to follow your convention given in the question, except I prefer to use capital letters for keywords (just a personal preference for readability).

I think with SQL formatting as with other code format conventions, the important point is to have a convention, not what that convention is (within the realms of common sense of course!)

I have white border of an asp:image control and i want to remove it but can't find where the problem is

I have to check if two images are similar or not in java using OpenCV, I am using OpenCV for that and using ORB

The number of matches that i get is same for the same image as well as for different images I am really confused ? Can you one explain how to compare two images and tell if they are similar or not using OpenCV

I am trying to extend this docker image which is provisioned with ansible and build successfully on docker hub at least, part of this image includes a user called play which owns a directory called /home/play/Code that has 755 permissions. I am using boot2docker on mac

the container starts correctly and I get a session with user root starting in /home/play/Code. If I add -u play to that commade I get a session with the play user instead in the same directory.

Now if I push that container to elastic beanstalk with their cli tool I get the following error

Now per another suggestion I dont have a CMD or an ENTRYPOINT in my docker file so I add those.

The image builds but now when I try docker run with the same options as above I get

This happens whether I try to start the session as root or as play. I get the same error if I push this dockerfile to elastic beanstalk so its not related to boot2docker Any idea what my permission problem is here? I have tried changing that directories permission to 777 to no avail

Allows me to run the container locally but afterpushing to elastic beanstalk I get the container quit unexpectedly error again

prints it. I suppose they are on the same machine becase you are listening on 127.0.0.1.

As is often the case for maintaining the state of a table view cell, the right answer is to keep the state in your model. In other words, if tempArray is your model containing a collection of objects that describe the table's contents, add a BOOL attribute to those objects meaning something like userAdded.

I'm assuming the solution you're mentioning in the comment is something like this:

Start at the left or right (so index = 0), and scan which bits are set (upto 100 operations). Name that set x. Also set a variable block=0.

At index=1, repeat and store to set y. If x XOR y = 0, both are identical sets, so move on to index=2. If it x XOR y = z != 0, then range [block, index) is contiguous. Now set x = y, block = index, and continue.

If you have 100 bit-arrays of length 22 each, this takes something on the order of 2200 operations.

This is an optimum solution because the operation cannot be reduced further -- at each stage, your range is broken if another set doesn't match your set, so to check if the range is broken you must check all 100 bits.

I need to represent 10 runner who run on a 100 meter track , and display the winner ( who finishes the track first ) and the time he took to finish the track . I am beginner so I got multiple error in order to achieve this.

I am trying to split a string into words but I want to keep, "a.b.c" as a word, and remove the punctuation only if it is alone or at the end of a word e.g.

I am working on RAF(Roku Advertising Framework) using bright script.

On above image we seeing (Ad 1 of 1) when playing ads. Please give me suggestions to solve this issue, Any help much appreciated.

But I get Schema specified is not valid. Errors: (195,6) : error 0019: Each property name in a type must be unique. Property name 'IngredientID' was already defined.

If I remove IngredientID from RequestedIngredient, the db will be created just as I want to. But I have no access to IngredientID. How can I set this up to have access to foreign key?

You cannot directly tell it to call the super method. target is only a pointer to an object, super does not have a separate pointer address from your self instance.

Also by assigning the target to self.superclass you are telling the target to be the class. Therefore your trying call a class method rather than an instance method which is not what you want to do.

The only way to do this would be to assign target to self and have a separate method such as:

I would try to use a different approach if possible. If you are expecting to act on the environment variable in ansible, you could instead set the value in an inventory group_vars file which would only be in effect for local provisioning vagrant. Other environments could use different values for the same variable by updating the appropriate inventory group_vars file.

IMO I don't think mutating the parameter values is a bad practice in general,
it depends on how you're going to use it in your code.

I am fetching data from the indexed database in HTML 5, I am able to successfully get the values but I want it to bind it to some data-grid view of ASP.NET
The code which I am using to get the values from the indexed database is

this allows me to store the data in the array, how can I bind it to datagrid view,

"Auto-increment" is always a problem when working with a distributed system, as it creates a bottle-neck: Each new increment needs to read the previous data .. like some other parallel requests.

Generally speaking, "auto-increment" restricts parallelism, specially on distributed systems.

Just create one view for that and use <include ... /> to include that view to your Activity's layout. In each Activity you have to modify it independently.

Sharekit provides a generic sharing mechanism but also exposes individual services. For instance, if you were to share a URL on twitter, you could write the following code:

Now for example, how to show the Name element of outputData? I try to print so:

Basically, I have a project set up in Restlet which uses JAXRS for mapping resources to paths and uses JAXB for serializing and deserializing XML to/from Java types. I'm currently trying to send a POST request in order to test whether it works, and I'm running into a bit of trouble. Here's my resource:

I am trying to use jqGrid clientArray to submit multiple updates at once. (I am trying to update multiple rows in one go).

This works fine, but I have no idea that how to retrieve clientArray and send it to the server? If anyone can post an example of sending clientArray to server, it will be very helpful.

i want insertion of data in this database through multiple users, U1,U2,U3, each having different userids & passwords.

These users would be created by MAINLOGIN , manually or via the winform application.

So while creating MAINLOGIN , i would give him permission to further create logins.

i cannot create MULTIPLE users, because for one database, only one user can be created under one login.

i dont want to use windows authentication. because if i know the system password, then i could simply connect sql via the application and insert wrong data.

Is there a way to set the InstanceContextMode through a custom service behavior implementing IServiceBehavior --> ApplyDispatchBehavior

now I have this line that i can't translate the 'placeholder' attribute with @Html.TextBoxFor, how can I do that??

Others have given you the probability calculation, but I think you may be asking the wrong question.

I assume the reason you're asking about the probability of the priorities being unique, and the reason for choosing n^3 in the first place, is because you're hoping they will be unique, and choosing a large range relative to n seems to be a reasonable way of achieving uniqueness.

It is much easier to ensure that the values are unique. Simply populate the array of priorities with the numbers 1 .. n and then shuffle them with the Fisher-Yates algorithm (aka algorithm P from The Art of Computer Programming, volume 2, Seminumerical Algorithms, by Donald Knuth).

(There are also other ways of going about getting a random permutation. It is possible to generate the nth lexicographic permutation of a sequence using factoradic numbers (or, the factorial number system), and so generate the permutation for a randomly chosen value in [1 .. n!].)

You've in the preprocessing servlet already set the queryResult in the request scope.

So you do not need to use <jsp:useBean> at all. Remove the following line altogether:

Because your servlet has set it as a request attribute, the object is already in EL available by ${queryResult}. But due to the strange design of the class itself, it's hard to properly access it in EL, so you'll ineed need to resort to old school scriptlets. You only need to obtain it first by request.getAttribute("queryResult").

Making some assumptions and, asserting that joining on the millisecond is nonsensical, fiddle here.

The return value from responseStream.Read is the number of bytes you read in that one read. It's not the total number of bytes read since you started reading from the file.

Also, dividing the number of bytes read by the total number written (i.e. writeStream.Length) isn't telling you anything useful.

If you want to update a progress bar, you have to know how many total bytes there are in the file, and how many total bytes you've read up to this point. So if the file is 1,000,000 bytes long, and you've read 450,000 bytes total, the progress would be 45% (i.e. 450000/1000000).

In your code, you have to get the file size from the FTP server. That's the total number of bytes you're going to download. Then you need keep track of how many bytes you've read up to this point. The basic idea is:

Update

The problem appears to be that FtpWebRequest doesn't supply a ContentLength, so you need some other way to get the length. The only thing that comes to mind is to request the length up front by doing a separate FtpWebRequest with the GetFileSize method. See Get File Size On An FTP in C# for an example.

Am i able to use a copy constructor with the new keyword? My code also shows the 2 obj pointers have the same memory address?

You probably want to use a SpannableString for this, which allows individual parts of a string to be rendered differently in a TextView.

When not including "NOT IN", you will retrieve the list of those people who are not allocated.

HTMLEntities seems to work but you have an encoding problem. The terminal you're printing on is probably set up for a latin charset and barfs on the utf-8 characters output by your script.

The reason '&' displays correctly is that it's an ascii character and thus will display the same in most encodings.The problem is that it's not supposed to happen alone in an xml document and could pose problems later when you feed your decoded file to hpricot. I believe the proper way would be to parse with hpricot and then pass what you're extracting from the document to HTMLEntity.

The two clauses: NewCount is Count + 1 and increment(NewCount,Count) basically have the same meaning. You didn't make clear that Count is an input variable and it has a base case of 1, so Prolog didn't know where to start unifying values for it. For example, you should use Count as an input argument as follows (it doesn't change much if compared with your version):

There are several ways to achieve this. You can track pitch (lower pitch values will be male, otherwise female). Or try to build a GMM (Sphinx cannot do this, but HTK can), with one model for male, other for female and another to children.

I would suggest to read the following article about SSL sockets in Erang that contains complete code of the SSL echo server and client.

Another option is placing an error container outside of your form group ahead of time. The validator will then use it if necessary.

If I stick with your basic structure I can offer a slight improvement. Try this:

It's not hugely better, but I like it better than using Amb. It's just a tad cleaner I think.

No. That app runs in another process. Its objects cannot magically transport themselves to your process.

On Android 5.0+, with user permission, you can use the media projection APIs to take screenshots.

I'm trying to build a record ID crosswalk table, "Final Crosswalk", I need to join Data.Reason = 1 Clean Reasons.Reason, but it's a memo field - thus the Where statement.

I can view this query, but I can't get it to export or update. I'm assuming it's an issue with the resource requirements of the Where statement (the table has ~1M records).

A while back someone posted an mpl::string to the boost groups. I think it may actually have gotten into the library. If that is the case you could implement something like this by providing your template string as a template parameter (an mpl::string) and then using some pretty profound meta-programming skills to parse the formatting bits in it. Then you'd use this information to chose an implementation that has the appropriate argument count and types.

No, I'm not going to do it for you :P It would be quite difficult. However, I do believe it would be possible.

The important thing about modifiers is that the alter the reference, not the object referenced. e.g.

Note that rel is not a valid attribute for img elements. Therefore you might want to use data-* attributes to store the additional information.

Additional note: this.src will return the absolute URL, even if the src attribute contains a relative URL. If you want to get the actual value of the attribute, you have to use $(this).attr('src').

Applications to not get restore state functionality magically but they support APIs that help doing it. Some applications do it well, others less well and others not at all.

In practice, for the applications that support it, it works quite reliably, provided the logout went cleanly and you've not out of diskspace or something similar fatal.

You may consider changing your approach, especially if you are doing a lot of GUI updates from your background threads. Reasons:

What I prefer is to do polling the background thread data instead. Set up GUI timer for say 300ms, then check if there is any data ready to be updated, then do quick update with proper locking.

Note, that while the text variable is updated very frequently the GUI still stays responsive. If, instead, you update GUI on each "text" change, your system will freeze.

you can also check status of response you are getting after hitting the API , like, means there is some problem in API

In the foreach loop, you already know that node is a /a/b in the original document - so to get just its c children simply use a relative xpath:

I am having trouble with my insertion sort method. It loops over an array of elements of a custom struct that holds the word and the number of occurrences. The array length is fixed at 1000. The sort removes duplicates. It think the problem is in the swap when a duplcate is found but I am using the same function for the sorting swap. I have played with it for a while and I just can seem to get it to work.

My program outputs the entire list, using length variable and outputs the following:

I know that the array holds 1000 elements of the word hello, so this output if confusing me.

I have a function that is used to find out if list a can be found in list b. If it is found, then it returns True. In my case it should return True because list a can be found at the end of list b. List a never changes and always contains the same numbers, whereas list b accepts numbers from the user and then uses sorted() method to sort numbers in ascending order. I should also add that the order does matter.

I have searched around and could find a subset method, which looks like this: set(a).issubset(set(b))) as well as using in method. Both of them did not work for me.

UPDATE: Using set(a).issubset(set(b))) for some reason always returns True. For example, if a = [1,1] and b = [0,1,2,3,4,5] then using subset method returns True, even though 1,1 cannot be found in b. I'm not looking if 1 is inside the list, I'm looking if 1,1 is inside the list.

Using in method when
a = [6,7,8,9,10]
b = [1,3,4,6,7,8,9,10] returns False.

Parsing XML with python using xml.sax, but my code fails to catch Entities. Why doesn't skippedEntity() or resolveEntity() report in the following:

Keep a counter using long, take the modulus, you don't have to worry about overflow as it will increase by 60 per second and your code needs to run for 292471208678 years before overflow.

I have a GIT repository on bitbucket, which I want my Jenkins Server to access automatically. This is only possible using public/private key authentication. So I created a key pair and uploaded the public key to bitbucket. The public and the private key are on my server in the .ssh folder of the tomcat user running jenkins. I am able to clone my project when I am logged in as that user on the server.

However I am unable to get jenkins to actually check out the code from bitbucket. It always says:

Well I assume that this happens because when accessing the repository over ssh I need to provide the passphrase for my private key and jenkins is unable to do this automatically. I read that it is possible to avoid beeing asked for the passphrase by providing a config file inside the .ssh folder containing the following content:

I did so, but as soon as I provide that file I can no longer clone the repository from bitbucket. Not even directly from the server, getting the same error message as shown above.

Did anyone manage to make this setup work? I also read the following thread here on stackoverflow that was of no use to me: How do i set a private ssh key for hudson / jenkins to access bitbucket? and I checked that tomcat really runs under user tomcat6 by creating an empty test project that simply runs "whoami". So I am pretty much out of ideas for fixing the problem.

I'm doing a WPF login interface. In my login panel, I have one login TextBox and a PasswordBox. As what shown in the first image below, there is a little human logo in the login textbox and a lock in the password box. I set the image into the textbox background, and then when i try to insert some word into the login box, the words will overide the human logo(image B). Any advice to make it right?

We ended up taking a different direction. It seems that iPad/Safari get to choose what happens to your PDF. We ended up taking the route of minimizing links in PDFs instead. The closest we got to an actual solution was hacks that some PDF readers use to change the protocol: eg ghttp:// for url that opens in GoodReader. Did not find this to be an acceptable approach.

No, there is no way to access anonymous classes from anywhere, except from inside them (i.e. otherwise than by this reference). Or by an explicitly declared variable.

Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on.

How can I resolve this issue? I just want to run the refresh in parallel, the refresh method runs the Paint Event which has code to render an image...

I want to sort the input of the user with sort in a case (and function). But I never used this before. Do I have to use an array or something?

Now I want that the last numbers are sorted and also pinged from smallest to the biggest number like this: 20 35 50 and also that if you have 2 times the same number, the script only pings that number one time.

I know there are many questions on SOF, but this is the "newest" one. The thing is, I'm trying to create and alarm app, and I know for a fact that there are alarm apps out there that works perfectly ( somehow ), even if the app is not running and is in the background.

My question is: how do you start playing sound after your app is already in the background ??

UILocalNotification is great, but you'll only get application:(_:didReceiveLocalNotification:) after the user has already clicked on your notification, so playing sound using AVAudioPlayer didn't work, i want to play sound regardless weather the user clicks on it or doesn't. Of course with Required background modes: App plays audio or streams audio/video using AirPlay in info.plist already set. Once the music starts playing, it keeps playing even if i go to the background.

I don't want to use UILocalNotificaation sound coz it's limited to 30 secs and only the able to play the sounds that are bundled with the application.

You need to hold a strong reference to the AVAudioPlayer btw, so it won't get released, and the audioplayer.play() won't do anything...

A trie (or prefix tree) sounds right up your alley. It can do the search on a prefix string of length m in O(m) I believe.

I solved my problem by creating a compound border attribute every time I set the border color, like this:

And I think the problem is that you want the listbox to be populated with the first item of the combobox when you load for the first time the winform

If I have requirements like this:When user did not log in,He can not see the top bar(menu list in the second row of the picture should be hidden),only after he logged in,the top bar is visible,I thought a lot about this but can not find the solution.I dont know how to use canActive hook to control it,anyone has an idea please tell me,thank u.

Let me be more clear about my question.When user loading page of structure like this.Where should I get and record the login status to achieve my goal,from route or somewhere else?

I've wired up the CompletionData no problem, inserting etc into the Avalon Edit control.

In the example below, I want new-obj to "match" New-Object* in the list and not do a partial find on New-DataObject.

Is there a flag I can set? Or do I need to override the search and implement my own?

In the XAML you're setting the property to the default value which will not cause the PropertyChanged handler to fire. The boilerplate Get and Set methods will never be called unless you call them from code because properties set in XAML call GetValue and SetValue directly (as is the case with wrapper properties on a normal DP).

To ensure the change handler is always called when a value is set you could use a Nullable<HorizontalAlignment> instead and set the default to null.

These warning occur at the end of my distributed computations, and not for all instances. So it is very likely that some other instances have terminated and thus "recently left the cluster" when this warning occurs.

But why does an instance leaving cause an unknown address? Does this mean the instance x giving the warning somehow found out that instance y has left, and the master hasn't yet found out and sends the address of y to x, causing this warning?

Should I take actions to avoid this warning? Does it mean that y forgets some cleanup it is supposed to do at the end so that the master immediately finds out that y leaves the cluster? The only cleanup the instances are performing is shutdown() of their HazelcastInstance.

Is the irregular exit at the end of my log messages caused by the inconsistency in the partition table?

The OS handles scheduling and dispatching of ready threads, (those that require CPU), onto cores, managing CPU execution in a similar fashion as it manages other resources. A cache-miss is no reason to swap out a thread. A page-fault, where the desired page is not loaded into RAM at all, may cause a thread to be blocked until the page gets loaded from disk. The memory-management hardware does that by generating a hardware interrupt to an OS driver that handles the page-fault.

Yes, this looks like VS2003 bug. Workaround is simple - use typedef, it works this way:

I'm using a DropDownList in the DetailView (EditMode) and I would like to disable it depending on the date of the system. For example : between the 18 June and the 20 June, make the dropdownlist disabled (gray).

In my Entity Framework, I have three related entities 'Client', 'ClientAddress' and 'LookupAddressType'. "LookupAddressType" is a master class specifying the type of available address type, like business address, residential address etc. ClientAddress depend on LookupAddresstype and Client. While saving a Client entity with relevant ClientAddress data, i'm getting following error.

I do not need LookupAddressType to be inserted. Here I just need the relevant lookupAddressTypeId to be inserted in clientAddress entity.

I am using GZIPInputStream to download pdf file I want to show the download progress of the file on a UI button. But, I am not getting the actual size of the file , what I am getting is compressed size due to which I am unable to show the correct download progress. This download progress is exceeding 100 as the actual file size is greater than the compressed size of file. Header content of file from server : - Following info I receive from server, from which I am using content-length which is giving compressed file size.

I'm trying to create a pivot table to hold some relationship data for some basic ACL functionality.

As you can see, the SQL syntax to add the foreign key constraint is missing the 'id' column name for the referenced table. Is this a bug in Laravel or is there something wrong with my schema code?

Alternately if you know your PHP version (hint: php -v) you can check the changelog for the bug number (69874) to see whether the fix has been applied for your version.

I am trying to run PCA on a dataset which I have stored into a 2D vector from a file as follows:

Now I need to run PCA on this for which according to my understanding I need to convert this to type cv::Mat. This is being done as follows:

When I try printing it out on screen after PCA computation i end up with garbage values. I just need to figure out how to run PCA on a 2D double vector. Any help with this or pointing me in the right direction would be great. Thanks in advance.

and we want to add 'editor' column which would get the current mysql user and insert it there and also updates it automatically similar to the behaviour of the TIMESTAMP datatype. Can this be done and if so what sort of datatype should I use (is there such a type as USER or should I use simple varchar) and what kind of syntax is involved?

ASP.net 5 ( MVC 6) still available as preview edition. Also they have changed some major changes so Owin the way it support in ASP.net MVC 5 will not support same way. As they have changed basic interface that support that functionality but today I came across article they provide information how can we use old Owin and integrate in ASP.net MVC 6.

FB.login and FB.api doesn't provide you success/failure reporting just like you trying to implement it. There is no second argument for callbacks...

FB.api callback get one and only arguments which is response from Graph API usually (but not always) containing data property, object fields, boolean false or error object (with message, type and code properties)

You can modify your loginHandler by correction of response callbacks to take care of right arguments:

Here is a solution using jQuery (works for bootstrap or non-bootstrap login box) :

You should print values of x and y in your hopper function. Since chips2 contains indices in the matrix with value 2, then the index [9][9] will be contained in chips2 implying x = 9 or y = 9 at some point.

Therefore matrix[x+1][y+1] would mean matrix[10][10] which does not exist. You should review your code.

More elegant with shorter and more readable using java.util.Random and IntStream

If the user is on the new-detail.html page, no data is present because the $scope clones an empty array. Is it possible to rerun the controllers when that information is received?

It automatically handles all your RSS loading and parsing so you don't need to worry about it.

Dates in SQL are represented as #year/month/day#, eg. today's date would be #2012/11/19#, and to make DLookup work you have to use this syntax:

Yes, DLookup is slow, you should not use it in a query. To check if EncDateTime is a holiday, you should join EncData and Holidays togheter, with this SQL Code:

This should return all EncData rows that are hoildays. It should, but it probably doesn't. Notice that EncDateTime contains not only the date, but also the time, so it doesn't match with HolidayDate that contains just the date. This works instead:

Notice that when HolidayDate contains a date only when that day is holiday, otherwise it will be NULL.

These are just some basic ideas to start. But don't forget that you cans use wizards to make your query, then you can always see how your SQL code looks like.

Using Alex's answer I was able to move multiple issues from one sprint to another. Adding step by step incase it helps anyone else.

I´m getting data from a database, the query works in the correct way, but I want to save that data in JsonArray.

I am using WINSCP functionality with an SSIS script task to move files from a remotePath to a localPath. I am also setting these files to readonly using:

This works to set the attributes, it is just that since I have pulled some data from the remotePath that is already on the localPath, the readonly attribute gets set back to 0 and the archive attribute gets set to 1.

Is there an easy way that I can just pull the files from the remotePath that aren't already in the localPath?

This would eliminate any overwriting of files and also fix my readonly / archive attributes situation

I would also add that transactional databases are meant to hold current state and oftentimes do so to be self-maintaining. You don't want transactional databases growing beyond their necessary means. When a workflow or transaction is complete then move that data out and into a Reporting database, which is much better designed to hold historical data.

So I'm working on a website and I need a drawer on the left side and on the right side. First, I've made the left one and it seems to be working great so I've decided to copy it and change the names and the CSS in order to make the same one appear on the right side, but it isn't showing at all.. I might've made a small mistake, I might've made a big one, but I can not find it. Hopefully some of ya'll could help me out with this. It's practically an X in the left corner of the window which slides in the drawer with info and the same thing should be for the right side as well.

You need a simple regular language over c1 and c2. The automaton you might write has two states: an initial state, in which no c2 has been encountered in the input, and in which c1 and c2 are accepted, and a second state in which c2 has been seen, and in which only c1 is accepted. This language can be described by the regular expression (c1*c2c1*), or by the content model

A more general form of the question (with two required elements) is described in this answer to a related SO question. As the number of required elements rises, the content model experiences combinatorial explosion; in those cases, the all-groups of XSD 1.1 are much more convenient.

This is a big subject indeed. When moving into microservices, you need to remember that a lot of your headaches are going to be operational (devops oriented) rather than "code".

Also, there's so much out there that at some point you will just need to make a decision, regardless if it's optimal. Things will change along the way in any case. Make the best decision you can at the moment, go with it, and tweak later.

Regarding your questions, REST is a common practice. There are also other options (WCF, Avro, whatever). Give yourself a timeline for a decision. If you know REST and feel comfortable with REST, take the decision. Try to see if you can build it so you can change / add other protocols later, but don't make it delay you too much.

Like Udi said, some architecture considerations are if you need to call this service sync or async (via a message bus). Also, yes, think about service discovery. There are several options (zookeeper, consul).

But again, there's a lot of information and ways of doing things, don't get swamped.

Everytime a user selects a timerange, it creates a kind of placeholder event for visual feedback to the user. This isn't actually an event yet, and it is removed when the user makes another selection.

It's triggered every time the user selects (clicks and drags) a time slot. In it, call addEventSource to add it to the calendar as an actual event. And then call unselect to manually remove the placeholder.

This is an open-ended question and there is no clear answer with different tradeoffs.. I'm not a PHP programmer, but something like the following should work.

You should choose $rescale so that the average score rescores to something close to 0. And play around with $spread until you're happy with how much your scores spread out.

The idea is that log turns a wide range of scores into numbers in a comparable range that can be positive or negative. Add a bunch of rescored scores together and you get an arbitrary real number. Then throw that into a logistic function (see https://en.wikipedia.org/wiki/Logistic_function for details) to turn that into a number in your desired range.

I'm developing Android app just for hobby, and I made an app, when I test on my phones works well, I tested on :

Works great, and no error at all... but when I tested on Samsung Galaxy S4, and Samsung Galaxy S3.. no background music (on Galaxy S4 and no background pics are shown ), and what I click I see report error message so application crushes..

In why doesn't PEAR use absolute paths? it's stated that PEAR doesn't use absolute paths so people can overwrite select PEAR libs with their own. Is that the only reason? And if so is there any evidence that people actually do that?

I mean, it seems like using absolute paths would resolve a lot of issues people have with using PEAR libs and if the only reason for not using absolute paths is a use-case that no one actually utilizes it seems like PEAR would be better off using them.

(I don't consider this question a duplicate but more as a followup; posting in the other question likely wouldn't get me any responses since that question's already been answered, so I post this new question)

Is a variable declared under Grails(1.3.6) controller action and class variable thread safe? i.e

It has not been mentioned yet, so I will point out that OpenCV has functions for scaling and rotating images, as well as an enormous number of other utilities. It may contain many features that are not relevant to the question, but it is very easy to setup and use for a library of its kind.

You can try to implement transformations like this manually, but the simple approach to scaling and rotating will generally result in a significant loss of detail.

I am not as familiar with rotations, but here's part of an example from one of the tutorials on the OpenCV website that I have edited down to the relevant parts. (The original had skew and translation in it also...)

You could define a lambda function which calls your static function. Or simply store function name as a string in that variable. You would also have to implement a handler code for the class that calls a function from variable.

If we start with a Hash whose default value is [0, 0] we can do (almost) everything—look up the month (or get the default value of it's a new month) and add 1 to the appropriate index (0 for false and 1 for true)—in a single step:

I have an app that uses a color picking dialog to change the app background color, and the text color. The color picker works fine, but when the app closes for any reason it reverts back to default.

the below code is the result of my research. The problem I'm having is all my text fields start off without text color, when i use the color dialog the colors change just fine, but are not saved.

I have just found out the error in my script. The 1st script works fine after correcting the error. I should have used th for the header row as I did in the html and not td. Also I have added the missing .hide() The 2nd script though hides the columns but will still show a space for any column it hides. Note that the correct script had been posted earlier but with toggle buttons, check box etc which didn't suite my desire. This script works fine without checkbox or toggle button.

This creates all the .o files in the current directory. How can I specify a different object directory in a Makefile.am? I failed to find this in the GNU documentation, although I am sure it must be there somewhere.

I had the same problem with Greek input, this patch from launchpad works for me too.

In the noscript section you could load a resource from your server. If the a visitor loads the resource, you know that he has JavaScript disabled.

I think that might have something to do that you haven't properly closed the files. I took the liberty to rewrite your code, without the chmod stuff (which I don't think is necessary)

As you can see I've used File.open(path) and passed a block. This has the effect that the files will be closed automatically when the block exits. I've also changed the delete/rename code to simply move the gziped file to the original path, which has the same effect.

I have one doubt in my mind, What is the default behavior of REST web services-Synchronous or asynchronous. If synchronous then can we create asynchronous.

And for the device capacity, which there may be better examples, but this returns the space that is reported by the system:

Note that the above example may return "14.37 GB" for a 16GB device (where 14.37 is the number the iOS reports, presumably the space after iOS is installed. So you can look at it as the user partition excluding the root partition.

You'll have to do quite a bit of drawing by yourself. This MSDN section deals with Custom Control Painting and Rendering and the documentation for Control.Region has a sample for making round buttons that you might be able to adapt.

I'd suggest having a look at the codeproject site as well, a lot of people have written articles there about customizing various controls

WebRTC signalling is driving me crazy. My use-case is quite simple: a bidirectional audio intercom between a kiosk and to a control room webapp. Both computers are on the same network. Neither has internet access, all machines have known static IPs.

Everything I read wants me to use STUN/TURN/ICE servers. The acronyms for this is endless, contributing to my migraine but if this were a standard application, I'd just open a port, tell the other client about it (I can do this via the webapp if I need to) and have the other connect.

For the sake of examples, how would you connect a browser running on 192.168.0.101 to one running on 192.168.0.102?

This is my first post so please bear with me. Here are the tables I'm working with and I'm only showing the relevant columns:

For each movement record, there are 2 or more stop records. The way this works, is that we create an order and create the stops. The stops are grouped into movements.

When the cnt_tare_weight and/or chassis_tare_weight are updated in the movement record, I need to copy this data to all other movement records for that order. I want to use a trigger after update to do this.

Here is what I've come up with but and I'm not sure it will work. I would like to see if what I'm wanting do is correct or if I'm missing something.

I have never created a SQL Server trigger before. I'm not sure if this will work or if I need to do something more. Do I need to create a trigger that calls a stored procedure? Or will the above work?

As far as I know the content isn't loaded when the div's display style is set to none.

I have an RCP product based on 2 features: my product feature and the org.eclipse.rcp feature. It worked perfectly at export time and at run time.

Last week I decided to add the error log view to my product. I simply added the view to my "persective" and the logview plugin as plugin dependency in my main plugin. Just work fine !!!

After exporting my product (through headless build) I noticed that when launching my product I have a lot of errors in the error log view (not acceptable for customers even if all is working fine). These errors are related to the RCP feature plugins and say:

the plugin org.eclipse.xxx (one error for each plugin of the RCP feature) has already been installed from /plugins/org.eclipse.xxx

Any idea on the way to avoid these errors ? I guess this means I have something wrong in my product configuration.

You can even implement this retrospectively by adding a new column to replace the schema, for example: Profile, then merge all tables from each schema into one in a single schema (e.g. dbo).

I have used an int for the profile column, but if you use a varchar you could even keep your schema name for the profile value, if that helps to make things clearer.

my suggestion is: just keep codding the way it is, until a problem rises or an extremely need for the change appears.

I would like to save CSV files that users upload to a blob. I would than like to retrieve the CSV file out of the blob in a format that I can use with the ruby CSV library. Any ideas on how I can accomplish that?

I'm trying to integrate stripe into my app. I'm following a Railscast (#288) but I'm getting the impression there a are few things that Ryan isn't mentioning explicitly.

My problem is that the plan_id on my app doesn't get transmitted over to Stripe. Once I generate a test transaction in my app and I log on to Stripe, it will show that a new customer with a valid card was created, but the plan_id isn't transmitted. I do have plans setup on stripe. But since no plan_id is submitted, the credit card never gets charged. So I've got customers, but no payments.

Here's my subscription/new.html.haml. I'm wondering if I need to assign a value to the hidden field "plan_id."

Here's my subscription controller. The params(:plan_id) is passed using a string query.

I successfully integrated the most recent AASM gem into an application, using it for the creation of a wizard. In my case I have a model order

Now I would like to give an administrator the possibility to create his own graphs through the AASM states. Therefore I created two additional models called OrderFlow and Transition where there order_flow has many transitions and order belongs_to order_flow.

No problem so far. Now I would like to give my admin the possibility to dynamically add existing transitions / events to an order_flow graph.

The problem now is, that I do not find any possibility to get a list of all events / transitions out of my order model. aasm_states_for_select seems to be the correct candidate, but I cannot call it on my order model.

I am trying to create an iPhone game with fairly large levels. Hard coding the platforms and physics objects is very time consuming. I have seen some people have made their own parsers for svg files to use in box2D, and Riq is selling levelSVG but it is a little pricey for me at the moment, and I only need basic features. Is there a tutorial on how to code a parser available online?

So there won't be a problem in using multiple directive in a single view if they are triggered according to data

I'm trying to write a predicate that checks if all tuples in a list are different. The following line works for a list with integers but not for a list with tuples:

member/2 works fine to check if a tuple is in a list but it is the select/3 that has problems with tuples. It gives a type error.

Although it is not object-oriented, Haskell offers a significant number of the features that interest you:

I actually think Haskell has quite a different feel from Python overall, but that is primarily because of the extremely powerful static type system. If you are interested in trying a statically typed language, Haskell is one of the most ambitious ones out there right now.

The best solution would be to use gradient fills (fillcolor="orange:yellow") - but though this is in the documentation, I wasn't able to make it work on my box.

You could use HTML-like labels as a workaround. You may need to split the label to have it centered, depending on your needs:

Thanks to all. The additional AND condition worked. I had actually tried that earlier but it didn't work when I was testing, in my haste I had not yet added the "completed" column to the table yet. Thanks again.

You need samsung certificate. Application with Certificate that created in Tizen Studio can be run only Emulator. Use Samsung Certificate if you want to run application on real device.

Reserved words are a moving target. If the dbms doesn't expose them through a public interface, there isn't usually a good programmatic way to get to them.

If you don't want to guard them with brackets, you risk incorporating symbols that are not reserved in your currently used version of SQL Server, but are reserved in some future version.

I think your best bet is to use the quoting mechanism your dbms provides, since it's designed to deal with exactly this problem. For SQL Server, that means square brackets.

As far as I know, mongodb doesn't support queries against dynamic values. But you could use a javascript function:

To speed this up you could add an attribute like "is_unresolved" which will be set to true on update when this condition is matched ( and index that ).

Get rid of that new at the beginning. It's Charts.newColumnChart(), not new Charts.newColumnChart().

If you have named your virtual directory the same name as your application then I could see how that could confuse you. If you had no virtual directory and just your application at the root of the Default Web Site you'd be seeing:

Is your virtual directory the same name as your application name? If so, that is why you see this.

Colon. Space + Underscore is used to split a single statement over multiple lines.

Your issue is not with Array, your question really involves escape sequences for special characters in strings. As the \ character is special, you need to first prepend it (escape it) with a leading backslash, like so.

You probably want to declare fields, and get the values of the parameters in the constructor, and save the parameters to the fields:

you have to MIME-encode your post: a binary post in an NNTP newsgroup is like a mail with an attachment.

the file has to be encoded in ASCII, generally using the base64 encoding, then the encoded file is packaged iton a multipart MIME message and posted...

i encourage you to read RFC3977 which is the official standard defining the NNTP protocol.

use StringIO to build a fake file object from a string (the post() method of nntplib accepts open file objects). email.Message objects have a as_string() method to retrieve the content of the message as a plain string.

The headers will be set by cake itself from the controller. It's not good coding (anymore) to set them in the layout (I used to do that, as well^^).

These days the CakePdf plugin has matured quite a bit into a very useful tool for PDF generation. I recommend using that in Cake2.x.

Your issue seems to be caused by the line break (which insert a space in the rendered html document). If you don't need that space b/w those two element then you can float both those element to left, it will ignore the space.

This will sum up the qty for refnum's in the map and once your iteration is over, the map will have the sums of quantities for each refnum. You will have to iterate the list once more to set the current qty to each item from the map [EDIT] :- Added the iterating time removal.

I think the problem you are having is that the getQueryString method you are using is looking for the "?" operator in the URL, as in a traditional GET request (e.g. ?id=1). Instead, try passing the domain as a parameter in the controller method. For example:

I've made an android app that uses the JSON Google image search API to provide images but I have noticed that Google have stopped supporting it. I have also discovered that Wikidata sometimes provides a image property on some items, however I can't seem to get the URL location of the image using the Wikidata API.

As far as I know, Mark and Sweep is only used for reference counting event listeners since they're the only ones that can have 'weak listeners'. Everything else is straight up memory reference counting. Essentially, your biggest problem would be cleaning up event listeners, but if the event listeners are within your class (listening to itself, or it's children or even outside events) they should be GC'ed properly if the object is dereferenced throughout your app (don't store it somewhere else).

If you let object or properties be publically visible, it is possible for other classes to references them and it could prevent GC of your class (it really depends how it's referenced and all). The only to combat that is to try to encapsulate as much as possible (one class handles it's own dereferencing; look into IDisposable) so that others can't reference and try to adhere to good coding practices (preventing spaghetti code).

One use could be dynamic control generation based on information that is only available from the bound data item at the time it is bound the Repeater.

I am building an eclipse plugin (a notes plugin, but its a eclipse plugin in the end). One of the plugins my plugin depends on needs to load a native dll.

The problem is, that fails depending on where in the disk such dll is. If it is longer than a certain threshold I get the error below

Using WCF In Silverlight services, typically we want to use the DataContract and Datamember attributes to opt into what we want to have serialized. This is what we send to and from the client. For most things this has never been a problem.

However, I have a few classes I am trying to share with my silverlight app, 'mature' classes, that I would like to send to the client full of data. These classes implement ISerializable which, doesn't like to play nice with the WCF service when I update.

I need to leave the ISerializable attribute on there because it is being used else where is some older code. Currently the way I see it is my best option being to have a new class to transfer the data through, if at all possible I would prefer not to have to write a class just for transfering the data but I am thinking that is what I am going to have to do.

Any Ideas on what I could do to get this to serialize through a service and still be able to keep the ISerializable tag on there?

We have a query that uses joinedloads to fully populate some Recipe objects using a single query. The query creates a large SQL statement that takes 20 seconds to execute - too long. Here's the rendered SQL statement on Pastebin.

The rendered SQL has an ORDER BY clause that Postgres explain says is the source of 99% of the time spent on this query. This appears to come from the relationship in the ORM model, which has an order_by clause.

However, we don't care about the order the results are returned for this query - we only care about the order when looking at a single object. If I remove the ORDER BY clause at the end of the rendered SQL statement, the query executes in less than a second - perfect.

We tried using .order_by(None) on the query, but that seems to have no effect. The ORDER BY seems to be related to the joinedloads, because if change the joinedloads to lazyloads, they go away. But we need the joinedloads for speed.

I changed the command to execute a call to a batch script which then called the print command.

I want to make my current website responsive. It's a huge dynamic website and I do not want to make a separate website for mobile or change the <Doctype> or <html>. Is it possible to insert a script that changes the <Doctype> and <html> tags if a website is accessed via a mobile?

The most obvious tool would be SQL Profiler. It will monitor every SQL statement, and thus every data change, that gets sent to the server and show you metrics about that statement, the account under which the statement was executed and a host of other pieces of information and it comes free with most SQL Server versions. If you only want to see data changes, you can add filters to only show Insert, Update and Delete statements.

If what you are trying to do is compare two databases to see what data is different between them, then I'd recommend something like Red-Gate's Data Compare (no I do not work for them). It is not free but invaluable for this type of column value by column value comparison.

I am working on an android app where I have done some realtime applications using pusher. I read about pusher webhooks and I couldn't quite understand the concept when I read it Here .

I have a little script which filters those domain names which are not registred yet. I use pywhois module. The problem is that it suddenly freeze and do nothing after several (sometimes hundreds) of requests. I think it is not a ban because I can run the program right after freeze and it works.

I would like to avoid this freezing. My idea is to count runtime of the function and if the time cross some line (for example 10 seconds) it repeats the code.

Do you have any advice how to avoid the freezing? Or the better way to check domains?

How to connect SQL server db 2008 with windows authentication from eclipse db perspective.

Short answer: You cannot: AFAIK, currently there is no way to do it from sqlalchemy directly.

Howerever, you can use sqlalchemy-migrate for this if you change your model frequently and have different versions rolled out to production. Else it might be an overkill and you may be better off generating the ALTER TABLE ... scripts manually.

The issue is that when a UIimageView is subclassed and called from the storyboard a different method is called for the init.

I want to use Facelets to build a static HTML prototype. This prototype will be sent out to people who do not have a running web application server such as Tomcat. Is there some way to compile a Facelets site at build-time (using Ant etc) into a set of flat HTML files?

In other words, Facelets is running at build-time rather than render-time, in order to produce static flat-file prototypes.

We have to get a legacy web application to run in Internet Explorer 11 and Firefox. The application does not set any doctype and therefore sends both browsers into quirks mode.

We have a table that needs to be scrollable, which is embedded in a div with overflow: auto. This works on its own, but our web application embeds this div again in a table and wraps the table with another two divs. See the fiddle here:

The wrapping table (the first -node in the HTML tree) seems to suppress the scrollbars. They reappear when one removes it. So while this structure does not have scrollbars (see fiddle above):

It would seem that one needs to format the table in a certain way to get it to display scrollbars again (or rather: not suppress the scrollbars of its child node), any suggestions?

We cannot simply remove the table from our application without compromising the rest of the layout, but we can add/modify css at will.

Well, it tries to link a static library into a dynamic one, and that static library (/opt/lib/python-3.5/lib/libpython3.5m.a) isn't suitable for that (compiled w/o -fPIC what makes it impossible to use it in a shared library). recompile that library with the flag (or simply supply one properly compiled) and re-try with Blender BPY.

I've just checked, Ubuntu-14.04 didn't have python-3.5 in the official repos, but there's a bunch of dedicated PPAs. But since it's the end of April of 16, it'd better to switch your apt sources.list to Xenial and update the system to the next LTS, if you feel brave, or just python if you don't :)

I am building an internal whitelist browsing filter server for a business. It is 95% operational. PowerDNS intercepts the DNS request and the LUA script correctly determines if the URL is whitelisted. The problem lies in the blacklist block page ... all I get is PAGE CANNOT BE DISPLAYED. The LUA script is getting to this line but the actual redirect never occurs:
return 0, {{qtype=pdns.A, content="1.2.3.4"}}
The 1.2.3.4 is where I put the actual IP of the PowerDNS server itself. Apache is not detecting that anything is getting to the server over port 80. If I navigate to 1.2.3.4 I do get the block page so I know apache is configured correctly and I have ServerAlias set to * to accept all domains. Thanks in advance.

I know you can put <% if %> statements in the ItemTemplate to hide controls but the column is still there. You cannot put <% %> statements into the LayoutTemplate which is where the column headings are declared, hence the problem. Does anyone know of a better way?

I am new to python and to linear algebra and I have a question about covariance of a matrix.

I have a 21 by 2 matrix, where the first column represents the average score(from 0 to 10) of the video games released that year and second columns are years ranging from 1996 to 2016.

I was playing around with the data and I noticed that by doing np.cov(X) I got a very interesting graph. I will list the graph below. It is my understanding that covariance shows the dependence among the variables in a dataset, but will it be correct to state that based on this covariance graph we can say that the average score of the games rises as the years rise ?

This is something that's usually done through the web server, so the answer depends on whether you're using Apache, Nginx, or something else. Here's how I do it with Nginx.

I typically have a directory in my site root called controllers. All of the files in controllers correspond to URL paths. For example:

Then I use the web server (Nginx) to direct the traffic (which is what it's built to do). So if Nginx gets a request for http://example.com/home, then it looks in the controllers directory for a file called home.php. If the file exists, then Nginx serves it up. If the file doesn't exist, then Nginx serves up some fallback page. Here's what the Nginx configuration looks like:

How do I convert these to data I can plot? I've been trying with the "convert" function, but can't get it to work.

When I manually convert it to something like [[7, 0], [2.5, 0], [-2.3, 0], [2.5, 2.7], [2.5, -2.7]] it works, though there has to be an automatic way, right?

I have a function U(x,y), of which I calculate the gradient and then check where it becomes 0, like this:

that gives me my list of points. Now I would like to plot these points on a graph.

If you re-used the application name (deleted the old application and created a new one with the same name) it could take up to 24 hours for the dns to be routed to the correct server. if you are going to do rapid create/delete/create cycles, you should use different application names so that you don't have to wait on DNS updates.

As others have mentioned, you cannot do this. But instead you can use ArrayList (or any other List) and where needed, convert it to simple array, like this:

Having a ViewModel gives you an extra abstraction between a single Model and multiple (versions of) Views

All in all it is just a guideline but be aware that what seems OK today might be not so great when you need to modify/update the application.

No, your code is not threadsafe assuming that the window handle (FWnd) is created in main (GUI) thread. A standard VCL approach is to call all GDI functions in GUI thread, via Synchronize or Queue methods of TThread class.

The thing that you are trying to do is to access the /storage folder just without read write permissions which is required by laravel.

EDIT: The directory should have the recursive mode enabled. You are not just giving permissions to one directory, but you are giving it to each and every subdirectory that you find inside that folder.

If you're just trying to run a one-off load test, you could manually modify the flags passed to the Kubelet on each node, but since that flag isn't even controllable by Kubernetes's Salt templates, there isn't even an option to control it with an environment variable.

The value was chosen due to performance limitations and will be drastically bumped up (to 100) in version 1.2 of Kubernetes, which is scheduled for release in March.

So that I understand, you have not yet built any ORM Entities? (CFC for each table)

If you have not, all you have to do is setup all your tables (use cfbuilder with a RDS connection to build your ORM CFC files)

Once you have all your tables referenced in ORM Persisted CFC files, you can do this with a cfquery tag and dbtype = "HQL" and return the data with QueryConvertForGrid()

Then just return the data you want to your cfgrid via json or directly on the page into the cfgrid tag.

I had this problem also but it is on win10.. After I have tried a lots of different solution from web .. Finally.. it worked to change connection string to fix this problem.. But I changed "Provider=MSDAORA.1" to "Provider=OraOLEDB.Oracle"

I encountered this error when trying to debug to run a web application after publishing from VS 2012 to IIS 7.5. After some hair pulling, I realised that the problem was the fact that I did not change the jquery script and signalr paths when deploying.

To solve the issue I had to add the virtual directory name ("TestingChat") to the path of the script tags for jquery and signalr.

I am given a task to make a feature that autogenerates a ticket ID for a list. However, I found out that the template used for the site is a helpdesk.wsp template. Now, I am having problems stapling the said feature to Service Requests because it is currently under LLISTS and not LISTS.

The client code is only send Person object using socket input stream and receive echo Person object.

In the avatar generator I'm working on I have several button events that do the same thing but with different body parts. I don't want to have different functions doing the same thing, so I want to use one function for all body parts.

Line 14 below uses the object propery 'AvGen.eyes.currEyesNr', but instead I want to use the one for the clicked button. What can I put in as an argument and how can I use the parameter in the function to be able to use the correct object parameter?

I am trying to modify "Text Body" style for paragraph in word 2010 so that the Below paragraph spacing is much less. But when I change that value it will not save it so that when I reopen word the modifications are gone.

The reason I want to save it is that when the document gets created using python docx and I pass the paragraph function the style it will be with the new values. Anyone have any ideas about this?

William Pugh, one of the authors of "JSR-133: Java Memory Model and Thread Speciﬁcation" maintains a webpage about the memory model here:

Stumbled upon this question and thought I would offer an alternative. If you run into trouble with popup blockers, you can use plain old HTML to launch a url in a new window/tab. You won't have as much control over that is displayed (scrollbars, toolbar, etc), but it works even if javascript is disabled and is 508 compliant:

After some data cleaning, I needed to reduce the list to a more manageable size. Since I am interested in contributors who have donated more than once, I have decided to try to limit the size of the dataset like that.

If you are trying it on same field you can try to build the query like this replace the 'reference' with your field name

For the disabled attribute I think it's the presence of the attribute that disables the element regardless of its value.

It guess one of the reasons could be to allow more values than just yes/no in the future. For instance, instead of visible=true/false, you can have visibility=visible/hidden/collapsed

This is really simple stuff but, as I am a noob with math.net, I may need to be pointed in the right direction:

Matrix-Vector multiplication takes too much liberty here. I need to enforce proper dimensionality checks. Should I just work with DenseMatrix, creating 1xn, nx1 matrices? This basically makes Vectors and DenseVectors redundant in my case.

Okay, I solved my problem and would like to answer my own question. I figured it would be better for the other users here.

EDIT: Thanks to Ignacio Vazquez-Abrams. It was him that helped me in #python Freenode. Should have credited him when I made this post. I didn't know he was in Stackoverflow.

It will identify the unique element of your entire page. No other element should be declared with the same id. The id selector is used to specify a style for a single, unique element. The id selector uses the id attribute of the HTML element, and is defined with a "#".

The class selector is used to specify a style for a group of elements. Unlike the id selector, the class selector is most often used on several elements.

This allows you to set a particular style for many HTML elements with the same class.

The Recurring Payments API is what you want. Specifically, Express Checkout would be for PayPal payments and Payments Pro (DoDirectPayment / PayFlow) would be for direct credit card processing without a PayPal account.

You have added the entry to root's crontab, while your Cloud SDK installation is setup for a different user (I am guessing ubu121lts).

We compile this with GCC compiler and want to find all members of otherClass object. We get the next DWARF dump:

We have a variable otherClass, which have a type of 0x131. This type have DW_AT_declaration flag, which means that this is non complete type. Type at 0x131 have all members of it's main class (OtherClass_var1 and OtherClass_var2), but don't have any information about derived members.

There is a definition for our base class and this definition have DW_AT_specification tag, which shows where to find a other part of this class (main part).

How can we correctly read this otherClass object? At this moment I have to store array of all types and when I get a DW_AT_declaration tag, I should go through array and find a type with specification to this type.

And how can I get a absolute address of derived members? We have a absolute address of variable otherClass. Then member OtherClass_var1 would have the same address as otherClass. Member OtherClass_var2 would have address of OtherClass_var1 plus a byte size of OtherClass_var1. But how can we calculate the address of derived members Base_var1 and Base_var2?

That is one way. It's nice and simple, but a bit messy. You could get rid of the storyboard and on each tick, increment a local value by the tick interval and use that to set your time. You would then only have one time piece.

Or... A more elegant and re-usable way would be to create a helper class that is a DependencyObject. I would also just use a StoryBoard with a DoubleAnimation an bind the Storyboard.Target to an instance of the DoubleTextblockSetter. Set the storyboard Duration to your time and set the value to your time in seconds. Here is the DoublerBlockSetterCode.

I almost forgot the TimespanFormatProvider. There is no format provider for timespan in Silverlight, so it appears.

All that stuff is re-usable and should live in your tool box. I pulled it from mine. Then, of course, you wire it all together:

And that should do the trick. An it's only like a million lines of code. And we haven't even written Hello World just yet...;) I didn't compile that, but I did Copy and Paste the 3 classes directly from my library. I've used them quite a lot. It works great. I also use those classes for other things. The TickFormatConverter comes in handy when data binding. I also have one that does Seconds. Very useful. The DoubleTextblockSetter allows me to animate numbers, which is really fun. Especially when you apply different types of interpolation.

As said in comments, for both ActionBarSherlock and AppCompat library, it's necessary to call requestFeature() before super.onCreate()

That article also describes a way to prevent the mobile device to sleep (which is not exactly what you may want), by calling the native function SystemIdleTimerReset() periodically (to prevent the device from powering down).

You can iterate over the returned drives from your WMI query and add the deviceid and "Disk GB" results to a string value. Then you can write the resulting string value to the Excel cell. One way to do this would be like this:

It is ultimately up to the vendor to define the filesystem / filesystem layout. So it might be in a different place. If there is no customized definition then the libraries will be in /data/data/your.package.name/lib.

In case it is in a different directory then System.loadLibrary will know that and load the library from that place.

My question : How to disable a User Control to draw it's background (or Region)

Note : I already tried to override and empty OnPaintBackground or set background color to transparent.

I'm trying to bypass winform paint for my custom user controls in a custom container. For that I thought to give a try to this : Beginners-Starting-a-2D-Game-with-GDIplus

My render loop is inside the DrawingBoard with all elements specified in the previous link.

So from there I've tried everything I could to disable WinForm to make some magic drawing in background. Tried to override and empty everything that got paint/update/refresh/invalidate/validate on Form/DrawingBoard/Elements but nothing allowed me to get my texture or drawing to not get cropped by the control background : (

I also tried to set the background of the Element as transparent and also to set Form.TransparencyKey = blabla with each element BackColor = blabla. But failed each time.

Hi do you guys know a site where other programmers could make suggestions about the code that I make? I always think that the code I make could be better and I also wish someone could like mentor me or point out some bad habits that I make. I code in Java.

The Wrap Layout might be a solution for you. It automatically moves components to the next line when a line is full.

I just want to obtain all the subsidiaries of all the commerces that has an specific tag, i want to do it with Subsidiary has the base class (i know that if i use Commerce it will be more easier), the reason is 'cause i convert it to a json value with the next format:

Well, i can do the query with Commerce has base class, but i think that maybe iterating the commerces to obtain the subsidiaries is more expensive that doing it in the query.

I don't want to load CommerceTag but i had it in joinedload 'cause it doesn't work with Join method.

No, the Activity will not remain on the stack, but its entry will be shown in the recent task list, you can click on that entry to re-launch this Activity just as you re-launch your application.

For MVC6, You need to decorate the controllers with Area attribute. if you do not prefer to add this to individual controllers, you may simply create a base call which has Area decoration and inherit your other controllers from that.

You do not need to put that attribute on your controller name, You can simply specify the area name in the area route registration.

And it made no difference if I included ob_end_clean or not. So your problem is probably actually how you are rebuilding the args array in each iteration of the loop.

Why not just grab all the right information in one query from the start along the lines of something like this:

Then you just just pop them into an array (or better yet object) that has all the pertinent information in one row each time.

If you update your google play services you need to update your res/values tag too.

On the other hand, when I use the init function which use default initialization parameters the encrypt function works well:

when there is a relationship between two entities and you expect to use it, use JPA relationship annotations. One of the main advantages exactly is to not have to manually make extra queries when there is a relationship between entities.

I have a dot net executable (build in Visual Studio 2008) that attempts to connect to remote oracle database from a machine that does not have oracle client installed. The error I am getting is

from what I have read so far I needed to add reference Oracle.DataAccess.dll. Oracle.DataAccess was not available for adding under my VS 2008, so I went ahead and got a copy of MSI package (ODTwithODAC1020221.exe from Oracle site) to add the suggested DLL file (I am not sure if there is compatibility issue between my version of VS/.NET 3.5 SP1 and the download). After I have successfully added the reference, i get the above error.

Right now I have made it so when a user input a number higher than 100 or lower than 1, it prints out "invalid". BUT what if i want to make it so when a user input a string that is not a number(alphabetic, punctuation, etc.) it also returns this "invalid" message?

I have thought about using if not ...isdigit(), but it won't work since I get the guess as an integer in order for the above range to work. Try/except is another option I thought about, but still haven't figured out how to implement it in correctly.

"These pattern match variables are scalars and, as such, will only hold a single value. That value is whatever the capturing parentheses matched last."

Is it possible to test your iPhone app on Xcode, not on the simulator, but on your actual phone before releasing it on the app store.

You can only use one character per range in a regex and most regex parsers don't understand multiple bytes using the \x notation. Use the \u notation instead.

So I've used both above, \x for the 2-char hex values and \u for the larger ones.

I have a small issue with my dropdown menu when switching to another page. When I press my menu label button, the navigation bar slides down and when I then proceed to another page the dropdown menu acts if it was open but it is not so when I press the menu label button again the navigation bar slides up instead of down and after that it works normally.

What do I do to make the slide bar return to normal state when I switch pages? I hope you understand what I mean, otherwise I will try to clarify

I have changed the drawMatches method to swap the "roiImg" and key points with "compare" and key points.

This stopped the assertion error. But due to swapping the values around when it came to retrieving the key points I also had to make some changes. trainIdx and queryIdx have also been swapped to account for the previous changes made.

I'm working on a mapping app using ionic and leaflet. Note that I am not using the leaflet angular directive, I am using straight JS for the leaflet map (I know, I know...).

The initial state in my app loads the leaflet map just fine. If I switch to another state and back to the map everything is also fine. However, if I launch the app, switch to a different state and open a modal window in that state, then return to the original state, the map is broken and displays a number of grey tiles. The map will not update until the browser window resizes or the orientation of the mobile device is changed.

I've seen other people report issues with grey tiles, which typically can be resolved with a call to:

Unfortunately this does not resolve my issue. I'm pretty much a newb, but I think the problem is that when the modal opens, the invalidateSize() method in the leaflet source code is run, since the map div is not visible, the 'size' gets set to x:0, y:0 which ends up breaking the map when I transition back to the original state.

I'm not really sure where to go from here. Perhaps I can use JS to dynamically resize the div and trick leaflet into thinking a resize event has occurred? How would I do this? Any other thoughts?

I was trying to implement a chat application with authentication. I followed this tutorial to make the chat application which uses Socket.io.

When I used this tutorial the server is listening at port 8000 whereas the client is running at port 8100. The Socket URL is at 8000 and the chat application is working perfectly. However when I try to use methods of Express such as app.get(), I cant seem to make it work. I think the cause is that the port of the local host is 8100 and I am listening on 8000. I am using app.get() and AngualrJS to authenticate using PassportJS. Please can someone help me out as I have been stuck on this for a while. Thanks and I would really appreciate any help. Maybe I am thinking about this the wrong way.

I have a simple unit test project on Visual Studio 2012 Professional. I want to open this unit test using Microsoft Test Manager and run it. Is this possible? How do I do this? Thank you.

I'm not sure if that's what you're looking for, but just as a quick example without having looked at the actual code but using the CSS from the Stackoverflow tag elements - you can just retrieve the value of the input on change(), create an element, append the value of input and an additional element to remove the created and appended element on click(). As the new tag is appended and not already in the DOM when the page is loaded, you can use on() to delegate this click() event from a parent element. Instead of document any parent element can be used to delegate the event.

Note: Content_available should be true and priority should be high then only u recevied the notification. when your app is in closed state

You need to keep the selected item index inside pager adapter instead. And on click of any item inside a fragment change that value.

I am working on Android onlineShopping application.I have to apply some animation.

Also, make sure that you REALLY need that cache. In my experience, 2-nd level cache rarely accelerates real applications and yet creates a lot of problems.

You probably want to just use Attributes to specify your validation rules. This is the namespace where all the basic validations exist: ComonpentModel.DataAnnotations. If you want to get fancier, this NuGet package gives you lots of extra attributes: Data Annotation Extensions. Both of these support client side validation with ASP.NET's MVC unobtrusive validation.

In my gradle configuration I have different build types. The defaults (debug and release, each with custom settings), and dev and beta build type (also with custom signing, custom proguard and custom applicationIdSuffix.

What I now want to do is to build the app package with for example the buildType beta (gradle clean assembleBeta). That starts building the app in beta, sees that it has a dependency to wear, and starts building wear. BUT here's the problem. The wear module is being built with the release build type instead of the same beta-build-type I used to initiate the build.

The custom build type configuration is exactly the same on the two modules, and thus manually building the wear module with beta build type does work. But having a wear module built with beta and packaged inside the app module also built with beta does not work.

The idea behind this assert is to check if first row after added ones was correctly moved. If there are some rows after inserted ones, then their data are compared. If there aren't any, your model should both in the line

should return invalid (empty) QVariant. If both return empty QVariant (as they should) assertion succedes, thus providing some level of error-checking even in case of no rows after currently inserted.

According to the stacktrace, angular didn't found the module ngAnimate. You probably forgot to link angular-animate script from your index.html page.

I want my canvas and background image to scale to any browser size which I have learnt is possible through this.

Setting the width and height using percentages causes whatever I draw on top to come out blurred. The reason for this I read is that it comes out blurry because the width and height of canvas set using css is different.

It is absolutely imperative that I keep track of the co-ordinates since I have written a collision detection logic using the original size of the image.

Is it possible to dynamically change the canvas size to fill the screen, redraw it and ensure that the collision logic works perfectly without blurry drawing on top?

Lets take an example here. The image floor.jpg that I want as the background of the canvas is 1200X700. I want the canvas to be 100% of the page width and height. My animated player that moves on top of it requires collision detection with walls which I have coded keeping in mind the 1200x700 image.

I have gone through the various similar question on this site, but can't seem to figure it out.

File.AppendAllText(@"C:\Users\vemarajs\Desktop\Test\newtest.txt", OBX1.Distinct().ToList() + Environment.NewLine);

This extracts the contents of each OBX segment at element 5 (after 5 pipes) and writes out a file called test.text, in my else statement I am trying to modify the original HL7 file by deleting OBX|2 and OBX|3 to have only One OBX|1 as we expect the number of OBX segments inside the HL7 file to reach 40 or more and we don't wan't to keep those many while returning the message to its messagebox.

How do I get the first occurrence of OBX|1 without saying the line number is 4, this might change.

The reason is that otherwise, arr[i] is interpreted as an array of 2 integers, which decays into a pointer to the first element (and that's the address that is printed).

Declaring it as a 1-dimensional array will make sure that arr[i] is seen as an int.

Note that whoever calls this function cannot pass a 2D array anymore, or, put another way, cannot make that obvious to the compiler. Instead, you have to pass it a pointer to the first element, as in:

In other words, the code should work, you just need to change the declaration of the parameter arr

To control the variables written, just change the view definition however you need. You originally asked about creating five CSVs, this creates two.

You have to use a view because PROC EXPORT does not respect KEEP or DROP data set options. I don't think using a macro to do something like this is a good idea unless you are very sure you know what you are doing AND you need to run it multiple times with different scenarios.

Here is a simple example of how to copy values from an input to another html tag:

The jQuery is all in onclick which pulls the value from the input using $('#myInput').val() and supplies that value as an argument to replace the html contents of the span $('#copiedValue').html(...).

I am building a RESTful data store and leveraging Conditional GET and PUT. During a conditional PUT the client can include the Etag from a previous GET on the resource and if the current representation doesn't match the server will return the HTTP status code of 412 (Precondition Failed). Note this is an Atom based server/protocol.

My question is, when I return the 412 status can I also include the new representation of the resource or must the user issue a new GET? The HTTP spec doesn't seem to say yes or no and neither does the Atom spec (although their example shows an empty entity body on the response). It seems pretty wasteful not to return the new representation and make the client specifically GET it. Thoughts?

This is not the recursive solution you were looking for, but an explicit one is generally faster and easier to read and debug anyway. @DSM pointed out that this is likely a homework question, so I apologize for misreading. I'll go ahead and leave this up in case it's enlightening to anyone.

What you can do to enforce a minimum width for your table is to add an extra row to your table which spans all columns which has a width of the minimum size that you desire. This will then enforce your td percentages when the broswer is resized or your iframe is small.

I am trying to firstly check if there is a specific key in my Application Settings Isolated Storage, and then wish to make a CheckBox appear checked or unchecked depending on if the value for that key is "true" or "false". Also I am defaulting the opacity of the checkbox to 0.5 opacity when no action is taken upon it.

Possible unintended reference comparison; to get a value comparison, cast the left hand side to type 'string'

I have explored storing data in an Isolated Storage txt file, and that worked, I am now trying Application Settings, and will finally try to download and store an xml file, as well as create and store user settings into an xml file.

mysqli_query() can only execute 1 query, if you want to execute multiple queries, you need:

gets responded with true and not false as expected, since the array[2, 3, 5] doesn't exist in the source array. Any ideas how can it happen? Maybe flatten is applied to multidimensional arrays?

Since this specific issue seems to be resolved but it hasn't been addressed in an answer, I'll make the general remark that when trying to debug an error that pops up in the jQuery/jQuery UI/etc files, it's usually not actually an error IN THAT FILE, it's an error in your usage of it that isn't actually breaking until it gets down into jQuery. So you really want to just figure out "what Javascript that I wrote was being run right before that broke?", and start there.

Use the file() function in PHP to split each line of the file into an array then set each element of the array equal to it's respective variable. For example:

Once buyer login to their paypal account during checkout, the buyer will be able to see their email and shipping address as shown in the image for PayPal Payment Standard buttons such as buynow, addto cart.

If you are using Express checkout Integration, you can use GetExpressCheckoutDetails API to retrieve the buyer information and display in the order summary page on your website(not in paypal checkout page). enter image description here

In Rails, you can organize controllers into folders and keep your structure nice with namespacing. I'm looking for a similar organizational structure in Symfony 1.4.

I was thinking of organizing multiple actions.class.php files in an actions folder, but all I came across was using independent action files, one for each action... like this:

But I'd have to develop a whole new routing system in order to fit multiple actions into that file, which is... silly.

Really I'm just looking to make Symfony into Rails, (again, silly, but I'm stuck with Symfony for this project) so I'm wondering if there's a better way....?

What's happening is the Dependency Property is getting Registered multiple times under the same name and owner. Dependency Properties are intended to have a single owner, and should be statically instanced. If you don't statically instance them, an attempt will be made to register them for each instance of the control.

You're sending something called "books.xls", and correctly signalling that it's an Excel spreadsheet... but it isn't. You've completely missed the step of actually creating an Excel spreadsheet containing your data (which is probably 80% of the work here).

Firstly, the k-means clustering algorithm doesn't necessarily produce an optimal result, thus that's already a fairly significant indicator that it might have different results from different starting points.

It really comes down to the fact that each cluster uses the points in its own cluster to determine where it should move to - if all the clusters find their way to the centre of their respective points, the algorithm will terminate, and there can be multiple ways this can happen.

Consider this example: (4 points indicated by . and 2 clusters indicated by x)

Both the left and the right side have converged, but they're clearly different (the one on the right is clearly worse).

To find the best one you can pick the result that minimizes the sum of square distances from the centres to each of the points classified under it (this is, after all, the goal of k-means clustering).

Basically, this query is used for pagination. I have two queries before this one.

I have 166,000 rows of data now and this query taking 1.23 seconds to return the result which is not nice to use when the data grows. What should I do?

I have files that are named CULT_2009_BARRIERS_EXP_Linear.dbf
and would like to rename them to CULT_BARRIERS_EXP_Linear.dbf . The files have a date prefixed with them which is always different showing when it was captured. I have tried to replace them with regular expressions. i want to test the string if it contains numbers and then rename. I have used

which partially works. But I would ideally like to have one rename command as it is good practice

Probably the easiest is getting a heap dump by VisualVM. JDK also includes related tools, as the jmap tool.

I prefer to have NO extra LIBRARY PATHS in Tools Options, in every Delphi version, and to have each project have its own search path.

They work like this (example using jQuery promises, but there are other APIs for promises if you don't want to use jQuery):

To summarize promises are an object abstraction over the use of callbacks, that are very useful for control flow (chaining, waiting for all the callbacks, avoid lots of callback nesting).

In the first if clause you assign a value to self.name which may either rely on assumption that self.name exists somewhere, or on assumption that it is new and needs to be declared, but in elif you seem to assume with certainty that self.name already exists, it turns out it doesn't so you get an error.

I guess your safest option consists of simply adding self.name at the beginning of dataReceived method:

this will get rid of the error. As an alternative you could also add self.name to init method of IphoneChat.If you need self.name in other functions not only in dataReceived then adding init with self.name is the way to go, but from your code it seems you only need it in datareceived so just add it there. Adding self.name in init would look like this:

I'm attempting to put a <p> element inside a <foreignobject> inside an <svg> node in chrome but I am not seeing the text. I have inspected the element and the DOM model shows the structure I expect. I created this jsfiddle by copying from the DOM model and lo and behold it works exactly as I desire in the fiddle.

After scratching my head for a bit I started looking at the properties in the two tabs (both in Chrome) and the only 2 things at this point that jump out me are that when I hover over the <foreignobject> or <p> element in the fiddle, it shows a grey box the area where it's displayed. When I do this in the real application, it does the same for the <foreignobject> but I see nothing for the <p> element. The second difference is that in the fiddle, the <p> element shows a height and a width of 54px and 100px (respectively) but in the actual application they both are reported to be 'auto'.

As an experiment, I attempted to set the height and width explicitly in the CSS for 'p' but chrome just shows this as an 'invalid property'.

Assuming this is the problem, I'm a little lost as to how to control a property that I'm not allowed to specify. Can someone help with some advice on how to debug this further? There's clearly something about what I am doing that is causing this but I'm not sure where to look next.

I don't know why I didn't notice this before but I see a difference that may help explain this. The fiddle shows the properties for the <p> element as:

I assume this has something to do with how d3 is adding the <p> element. I will try to create a fiddle that creates the elements with d3.

I am newbie in using of await/async and windows phone 8.1 programming. I need to run async method simulateously in more than one thread. May be four, because my phone has four cores. But i cannot figure it out :-(

Four threads can be ensured by using of a semaphore object, but how i can run it in simulatously running threads?

EDIT: This is my code which explores folder structure and log metadata about files into database. I want to speed up execution of this code by calling method "async LogFilesFromFolderToDB(StorageFolder folder)" simulateously in separate thread for each folder.

You'll need to subclass UITableViewCell and override -layoutSubviews. When the cell's editing bit is set to YES, -layoutSubviews will automatically be invoked. Any changes made within -layoutSubviews are automatically animated.

Seems like it would make more sense to compute the parameters within if/else or switch logic, store them in variables, and then call the function afterwords with whatever parameters you computed.

I have many elscreen tabs(frames?) that are horizontally and vertically split. I'd like to be able to save the current buffers, windows layout in each frame, and the frames themselves.

In short, I'd like to be able to close emacs and re-open with relatively the same state as when I closed it.

The issue was the Class assignment that was with the Search Icon. After removing the line class: col-mw-3 it ran fine, and in all of the browsers. Also make sure nothing is covering the <a> Tag as well!

To go from an DateTime in the "Excel Format" to a C# Date Time you can use the DateTime.FromOADate function.

If you are wondering where the discrepancies in Excel's date handling come from, it's supposed to be on purpose:

I have some signup form that had email and login text fields as table cells and signup button as button in footer view. That all functioned superb, here is the code

By using [self.tableView.tableFooterView addSubview:...] buttons are not shown and if I use some other UIView, place buttons there and then say that the footerView is that UIView, I see the buttons, but am unable to press them.

I'm trying to add line numbers using NoodleLineNumberView. The issue I'm having is that the line numbers dont line up properly with thier line number.I have to type 16 lines, then line 1 gets marked as line 16. If I scroll down past the top of the text I can see the other line numbers there, its just like all over the are shifted up.

I subclassed a NSScrollView and added this bit of code. Thats all that should be needed. Is anyone else having this issue, or solved it?

You can use input to accept a string from the user. As you'll have two co-ordinates to punch in, perhaps call this twice. Once you get the strings, cast the locations to integer via int().

If you want to generate random locations, you can use random.randrange(). The syntax for random.randrange() is like so:

This will randomly generate a number from start to stop excluding stop itself. This is pretty much the same as with range(). The first method assumes a step size of 1, while the second method you can specify an optional third parameter which specifies the step size of your random integer generation. For example, if start = 2, stop = 12 and step = 2, this would randomly generate a integer from the set of [2, 4, 6, 8, 10].

I'm trying to create an ICAL file based on a single entry inside an Expression Engine channel but my methods of accomplishing this are failing. I've tried the following:

I haven't tried just making a flat file each time the single entry page is accessed with fwrite() and linking directly to it, but that seems like a costly move.

Is there a way with PHP to make the file when I click a button? Maybe firing off a function written in the page so I don't need to pass or detect the entry_id?

This is likely a config issue, but I'm new to Webpack and haven't been able to figure it out after a few days. I'd appreciate some help!

With a completely empty entry file, I get the following error when trying to run webpack.

However, if I comment out the jade loader line in webpack.config.js and require the jade file with the inline syntax require('jade!template.jade') -- everything works okay.

To get the directories and files to an unlimited depth, combine that with a recursion method based on System.IO.Directory.GetDirectories("path") - should be pretty straightforward methinks.

First of all the refresh token process is critical process. In my application and most of applications doing this : If refresh token fails logout current user and warn user to login .(Maybe you can retry refresh token process by 2-3-4 times by depending you)

I recreated my refresh token using HttpUrlConnection which simplest connection method. No cache , no retries , only try connection and get answer .

I see base64_encode can encode values, but without a key. I need a function that takes a salt and data, encodes it, and can be decoded with the same salt (but if you try to decode it without the salt, it gives you gibberish).

Is there a PHP function for this (can't find it, only modified versions of base64_encode).

When we are using ViewState or cookies or cashing or sessions where are we storing the information? I know when we use sessions we can store data in sql server or web server. is there any other way we store data when we are using sessions.

One more questions when i get the data from sql server and bind it to the dataset or datatable where that data is going to store(the dataset records)?

I want to play animation on a key on custom keyboard. I've created the custom keyboard and everything is working fine, except the animation which is kind of popping up of key. I'm accomplishing it through AnimationDrawable. When animation.start() is called, only the first frame of animation is shown and it stucks there. Below is my simple code for animation.

Now I want to know how can I get the exact view handle of any key or why this animation is not working. KeyboardView.Key.icon is just a drawable. Given is my enter_button_animation.xml:

just make sure the file is maked as "Resource" in visual studio. Alternatively you can mark it as "Content" and use it like this:

I don't know if you need to assign the background programatically (because you can do it in markup), but if you do here is what you need to say:

First, your code does not have any effect. Hash table "breaks" the order. The order of elements in hash table depends on the particular hash implementation.

There are 2 types of Maps in JDK: HashMap and SortedMap (typically we use its implementation TreeMap). BTW do not use Hashtable: this is old, synchronized and almost obsolete implementation).

When you are using HashMap (and Hashtable) the order of keys is unpredictable: it depends on implementation of hashCode() method of class you are using as keys of your map. If you are using TreeMap you can use Comparator to change this logic.

If you wish your keys to be extracted in the same order you put them use LinkedHashMap.

I am using BackgroundWorker a lot and can tell that RunWorkerCompleted event is definitely ran in UI thread. Also, you can pass the DoWork result to according eventArgs field and then, in RunWorkerCompleted take it from eventArgs to perform some UI-dependent operations with it, as mentioned here

Note that Apple's has the stylised swift in its logo heading downwards; the parallel scripting language Swift is heading upwards :)

To try Apple's Swift in a similar way, you'll need the Xcode 6 beta and a "playground" file.

I recommend this. If you have a emulator preview connected first go inside Android Wear app to the emulator and choose FORGET.

I'm trying to view our peak bytes received/sec count for an eventhub in order to scale it properly. However, the portal is showing vastly different results from the "daily" view to the "hourly" view. This is the graph using the "hourly" view:

From here, it looks like I'm peaking at around 2.5 MB/s. However, if I switch to the "daily" view, the numbers are vastly different:

So I can't make sense of this. It's the exact same counter, showing vastly different results. Anyone know if the Azure portal performs any "adding" or similar?

Edit: Notice that the counter is "bytes received per second". It shouldn't matter if I look at the hourly or daily view, the number of items per second shouldn't be affected by that (tho it clearly is).

Most or all of Endeca's objects have internal constructors. I'm working on a good project that lacks great test coverage around the Endeca API, are there any good strategies to unit testing the interactions with Endeca?

We can then mock our own type, DimValue. Is this the best way to keep their API as testable as can be? Or is there another method that is preferred to this?

The h values need to be adjusted for the three cases prior to calculating the cos values dependent on them. i.e.:

You will also need to make sure that none of the rr,gg,bb values end up outside the 0..255 interval:

In your case, we decided to expose our web app functionality as web services, because of:

The kind of web services you use depends on your requirements: people normally expose their API as a REST api, which is more or less an http CRUD wrapper over your application entities. You can use standard SOAP web services, which is more of a procedural point of view.

I don't like static data members much, the problem of initialization being foremost.

Whenever I have to do significant processing, I cheat and use a local static instead:

This way, the exception will be throw only on first use, and yet the object will be const.

This is quite a powerful idiom to delay execution. It had a little overhead (basically the compiler checks a flag each time it enters the method), but better worry about correctness first ;)

Guideline: only use static or global variables instantiation for simple objects (that cannot throw), otherwise use local static variables to delay execution until you can catch the resulting exceptions.

Unfortunately, it is illegal to reference a variable/param in a match pattern in XSLT 1.0. However, you can reference your $lang parameter any time you apply templates. So, for example, in the root template (i.e. a template that matches / or some other sufficiently top-level node), you could specify that you only want to apply templates to elements that have an xml:lang attribute equal to the value of your param (or no xml:lang at all):

This won't process any undesired elements and no other templates need to specify the language to match.

A good reference to how to accomplish "invisible" instance variable declarations can be found here with credit respectfully given to Matt Gallagher.

Is there a way to do an accent insensitive search using grep, preferably keeping the --color option ? By this I mean grep --secret-accent-insensitive-option aei would match àei but also äēì and possibly æi.

I know I can use iconv -t ASCII//TRANSLIT to remove accents from a text, but I don't see how I can use it to match since the text is transformed (it would work for grep -c or -l)

I have a controller in which there is a "viewless" action. That controller is used to set a variable called @@ComputedData={}. But the data is computed based on a csv file a user of the application uploaded. Now are users going to see their specific data or will the @@ComputeData be the same for all users? Could someone explain me this concept? I'm really shaky on it. Thank you in advance and sorry for the noob question.

This is my story board. I want to set the ttitle for this FrontViewController So I did this in my FrontViewController

With a layout as shown in the example and the range in Sheet1 named array =VLOOKUP(A2,array,2,FALSE) should show in ColumnC the value from the Sheet1 cell immediately to the right of the value as specified in A2 (of Sheet2). The same formula in D2 with ,2, replaced ,3, should give the corresponding unit price, so appending *B2 should give the Cost. Both formulae may be copied down to suit:

I have a broadcast receiver that works fine but now I want to send send notifications to status bar. Since BroadcastReceiver cannot do it directly it looks like I need to create a service to do that for me correct?

Other than a few small tweaks it's that code. I start the service from the broadcast receiver with context.startService(new Intent(context, AlertUser.class));

What happened is it did put out the msg in the status bar. then when I did a clear and had it generate a new msg the service code did not execute. Do I interact with he service differently once started? From what I read no if part of same process.

Also how would I share information like a string from the the BroadcastReceiver to the service to that it is info to display in the notification?

Your problem is thinking of the state as being all the permutations of what people can see. In general you should just be thinking of the state as the facts of the situation, and calculate individual views of those facts as they are needed.

If one player (eg, A) cannot see another player (eg. B), then you just don't send player B's information to player A until the situation changes.

The answer suggested; [theTableView reload] definitely works fine. If you update the table every view seconds, however, your users will going to hate you and down-vote your app. No question.

Try to capture the reloading data in a notification handler. In that handler, check if the updated data belongs somewhere between the currently visible cells, if so, update the currently visible view. If not, ignore the updated data (but do add it to your underlying model). If the user scrolls further, after your update, cellForIndexPath: is called and the updated data will be drawn automatically.

reload is quite heavy to do every view seconds, certainly with a lot of data. drawing might get screwed up or worse..

If you need to do AJAX request, turn-off the VerifyCsrfToken middleware on your Kernel.php file.

You can also edit your VerifyCsrfToken.php middleware file to exclude certain URLs like this way:

/** * The URIs that should be excluded from CSRF verification. * * @var array */ protected $except = [ 'ajax/*', 'api/*', ];

Is it possible to implement message segmentation using JMS as it is in using Native IBM API as shown here. One posible solution I have read is message grouping for JMS. is anyone using this an alternative solution to Segmentation, using JMS?

How can I render {{#if current_user}} ... {{else}} ... {{/if}} without nesting hs_else in hs_if?

I think I should remove {{/if}} from output, but I can't find way to do it in helper.

It is hard to help unless you post a bit more detail and some code. Without that here are some suggestions that might help.

You will need a submit button or some JavaScript to post the form inside the partial. If you have another form on the page which you are submitting, it will not include data from other forms and inputs on the page.

Also to form has to post back to a controller action, a partial just a helper to render a view inside another view.

The answer is correct in a certain context, for simple select statements over a DB link, you'll get this error:

I also had trouble finding definitive documentation on this...but we just ran into the same issue in our data warehouse. However, there are several work-arounds available, pulling the data over or creating a view for example.

When I try to load my own date using the NN pattern recognition app window, I can load the source data, but not the target (it is never on the drop down list). Both source and target are in the same directory. Source is 5000 observations with 400 vars per observation and target can take on 10 different values (recognizing digits). Any Ideas?

I have developed an online exam using the Moodle software which is written in PHP. Now I want to restrict the person who is taking the test without being able to navigate to other tabs or other windows by generating a mouserover pop-up.

Is there a possibility to restrict the user with this code and in that case where to append this code to the moodle's actual source code??

Hyperlink tag doesn't have a close tag </a>, if you want to close it make it like this:

I've got a Ruby web app running on Heroku with a Postgres database. I've noticed the auto-incremented IDs have a gap in them around the time that the Postgres database was under "maintenance" by Heroku.

The maintenance by Heroku happened in between the two records (2961 and 2994) being created, at 2016-02-15 04:00:00.

I've seen an explanation that a failed transaction will result in an ID being skipped over on the next successful commit, but I can't see anything in the application logs to indicate that any records were being created around the time.

I'm not sure I understand fully what is happening in this scenario but here is a solution to your problem:

close() - "Close the page and releases the memory heap associated with it. Do not use the page instance after calling this." <- This is from the phantomjs documentation. You need to create a new page instance if you want to continue opening sites. Hope this helps!

With the advent of dynamic parallelism in 3.5 and above CUDA architectures, is it possible to call linear algebra libraries from within __device__ functions?

Can the CUSOLVER library in CUDA 7 be called from a kernel (__global__) function?

I have tidied up your query a little (although this won't make a massive amount of difference to performance, and there may be typos as I don't have VS to hand). From your edit it seems you are a little confused by deferred execution in LINQ. callDetailsForNodes does not represent your results - it is a query that will provide your results once it is executed.

If you have to do all this querying in process I suggest you add a ToList after the first select and run that in isolation. Then add ToList to the Where clause. Calling ToList will force your query to execute and you will see where the delays are.

One final note - you should pass your records directly to ObservableCollection constructor rather than calling Add for each item. Calling Add will (I think) cause the collection to raise a changed notification which is not a big deal for small lists but will slow things down for larger lists.

I tried to convert a simple React project from JavaScript to TypeScript, but somehow this doesn't seem to work.

First VSCode shows me sometimes that react isn't a module, even if I installed it with typings and added the typings/index.d.ts to the tsconfig.json files list. When I restart VSCode it works after opening a few files, but it never seems to work right away.

Then I use history and typings also found a history type definition and installed it, but when I try to import history/lib/createBrowserHistory TypeScript doesn't know anything about it and talks about missing modules again.

The Idea is that package and config file is already there in blobs within some container and I can deploy my service when I am using Configuration = File.ReadAllText(ConfigurationManager.AppSettings["configFilePath"])(which takes the file from the local path and working fine as expected), but since I don't wanna do that I am trying to use the config file from Azure blobs, but File.ReadAllTextis not taking the Uri of my file which I checked is fine and giving System.SystemException {System.NotSupportedException} withbase {"The given path's format is not supported."}.(as its looking for string parameter)

Email address is accessible for the authenticated user as long as you request "r_emailaddress" permissions upon authorization.

Take a look at the Oauth Login Dialog that's presented to the user to authorize the application. Notice how "email address" isn't presented as one of the profile fields that the application wants to access. You'll need to modify this line in your code:

I was used to naming my session variables the "normal" way, kinda like when I want to keep track of user details, I name them:

I am worried that they may be in conflict with other session data when I am browsing sites in the same browser, or will there not be any conflict at all(once I tried to simultaneously run two of my projects with the same session variables, residing in the same server, and obviously, things got real messy).

Calculating out of basic logic, theoretically 1 GHz can do 1 billion calculations/second.

am working on a c program that should log data from a norma 5000, but it seams like the normas tcpconnection randomly closes after an arbitary time (0.2-6h) but i need to log longer than that.

when it Closes the Connection i can just restart program and it will continue to log. so i got the idea of just restarting my socket when the tcpconnection breaks. but my restart dosent work every time.. the function i Think you want to look at is shutdownCon, init and main.

winsock errors i get when the tcp Connection stops working 10053 (WSAECONNABORTED) or 10054 (WSAECONNRESET).

There are several ways to achieve what you want as the other answers point out. If you want a bit of safety checking then I'd use TryParse:

The problem was that the below variables initialization code was never getting executed:

Creating an init function that had the above lines and running that function before any others like execute() worked.

When comparing using an If statement, you cannot say If A = B or C. You are supposed to compare is separately. If A = B or A = C Then. Here each OR is its own Boolean statement i.e it will be evaluated separately.

When you have multiple such comparisons, it is better to use a Select Statement as shown in the example above.

This may not work in your scenario, but you can invoke a method from a binding using an ObjectDataProvider. Here's a quick example:

Again, this may not work in your scenario, but it does illustrate a way to pass a parameter to a method and use the return value entirely in XAML. Here's a resource for more information: http://bea.stollnitz.com/blog/?p=22

CAUTION: Proceed at your own risk. Writing block placement strategy is extremely complicated and risky. It's seems a code smell that your apps need to determine how replicas are placed. Think about if you really really need to write block placement strategies. Having warned you, proceed if you want to know how to accomplish this. Typically this feature is used to control how well balanced a cluster is. E.g. one of the strategies that was built by one of the Hadoop vendors is to place blocks on the disk with the lowest percentage disk used.

I suggest you to create json object from your vars and pass it as argument, something like:

I'm trying to load windowed sub-application in another windowed application, The requirement is to replace one loaded application with another on user action.

I tried the documented method of unloadAndStop() on the swfLoader in the main windowed application, but somehow during memory profiling I could see the instances of those applications were maintained in the memory even after explicitly running garbage collection.

Where as If I make those windowed application as modules, and then try to load them using the Moduleloader things work smoothly and unloaded modules are removed from memory.

You don't have UINavigationController into your pop-up, so it works normal. Change it to support navigation like this:

The following code snippet illustrate an example of usage and creation of an OWL expression using the OWL API (taken and adapted from there):

Basically, I would like every cell row to be the same size and when a cell matches with a specific name, I want certain cells (specific 2 sets of rows preceding the name) to merge and center while others just merge across but that way some cells in the column have one number while others have a percentage and fraction as seen in this picture example above.

Here is some pseudo ish code to give you an idea: basically, if a cell in the A range matches a color (or whatever I put), then we want to merge and center two rows of cells and the 3 columns. Else if the cell in the A range matches a name (or whatever I put), then leave the cells separate but merge across maybe.

Each list item is 960px wide , items are floated left and only one item is shown in the container at any given time. Clicking back for forward will animate the li by their width making the next or previous visible..

The problem is that for now there are 4 items. So I either need to add the first item to the end or the list or the last to the beginning of the list when clicked as the code I've commented out.

Watching this in firebug it seems to be rearranging the content as I hoped but it's not working so within the browser (getting some very odd results - jumping to the 3rd when the second should be visible etc).

The other solution perhaps would be to use an if statement to say (was we're manipulating the left property) - when back is click if left = 0 do nothing or alert there are no more in the list - then if forward is click to say if left = 2880 do nothing as you'll be at the end of the list..

I am receiving some json from a web service. I parse this using the TouchJSON library. I keep the data around for the user to change certain values and then I want to return it to the web service.

The JSON object I get contains NSDictionary Objects within the object, like this:

If I want to change values in this dictionary, I can't because the returned objects from TouchJSON are not mutable.

or is there a way to have Objective C make an NSDictionary and all its children mutable?

or do I have to just go through every NSDictionary in NSDictionary and copy all data into a mutable copy and then reinsert everything?

The decision of whether to override the method or use the event handler often times comes down to how much control you need to have over what happens during the execution of that method. Overriding the method gives you full control of the method, whereas the event handler only runs after the method has executed.

If you need a high level of control over what happens during that method, I would advise overriding the method. If you simply need to run some code after execution of the method, I would use the event handler.

Along with boosting during search, you can also boost fields differently during indexing. This means that a general search for a term that could show up in either field would still give a better score for those that match your preferred field without overtly stating where you're looking for the term.

It seems like your question boils down to "how can I dynamically add a method to an object", the the short answer is don't do it (1). Objects can have attributes which can be functions, and that's fine, but these functions do not become methods and don't behave like methods. For example if foo.attr is sum then foo.attr(x) is the same as sum(x) not sum(foo, x).

Your question has a certain functional "aroma" to it, if you wanted to drop the class/object stuff and go the fully functional route you could do something like this:

If that doesn't appeal to you, I would suggest thinking of the func and parent attributes on your Foo class as data attached to your objects, not as methods, and work out the problem from there. The logic associated with your class should live inside proper methods. These methods can refer to the data as needed. Here's my very simple example:

(1) Methods belong to a class not an object, so the question should really be how can I attach something to my object that behaves like a method.

I have a user model and I need to display all users that have an id of smaller than 100. My code is

I have an app that gets opened from another app via a URL scheme. The URL contains signup tokens. As any app can register the same URL scheme as my app, I am concerned a "fake" app can do a man-in-the-middle attack and capture the signup tokens.

My idea is to check that the URL scheme does not open another app when my app is first opened.

From a security perspective, if the URL scheme opens my app the first time, will it always open my app in the future?

As you can see that at the last line I am making the second tab to be shown when I open this tabbed activity and that is what it does but actually it first calls the OnCreate of FirstActivity and then calls OnCreate of SecondActivity before showing the SecondActivity. (The OnCreate of ThirdActivity is only called when I tap on the third tab to actually see that activity, which is absolutely fine).

I want that the OnCreate of FirstActivity to be only called when I tap on the first tab because:

I'm wondering if there is a way to change a specific word in all of the files within the /www/ directory using command line. Just looking for a faster way to change out a specific word so I don't need to open all the files manually! Thanks!

I am trying to run some php from the command line but the php in my class is not being hit.

If you have that textfile, you might just put a rename at the beginning of each line and save it as .bat.

(E. g. with Notepad++, Search Mode = Extended, replace \n with \nrename, maybe check first and last lines)

Is it possible for a Makefile to determine what binary format the compiler is targeting (i.e. PE, ELF, Mach-O, etc.)? Maybe by running the compiler or assembler with certain options?

Or can I accurately determine this from the OS (by running uname -s or something of the sort)?

Generally by convention you wouldn't choose a list or a tuple just based on its (im)mutability. You would choose a tuple for small collections of completely different pieces of data in which a full-blown class would be too heavyweight, and a list for collections of any reasonable size where you have a homogeneous set of data.

I agree with most of the others here. I think you should really try to uncomplicate things by using another already build free option like itunes, Winamp or WMP. If you really want to learn something new, do this just for fun after when you won't be under so much pressure to make it work.

Since everything is an object in Ruby, classes themselves are objects of class Class. By calling class << self you open up Class definition from the inside of Test and inject few instance methods. Since Test is an instance of Class, you can call those methods same way you call instance methods on your objects: Test.hi.

I have this Generalization relation ship between some classes in my class diagram. FirstClass as a base class that has Name attribute, SecondClass as a derived class that the FirstClass is it's base class and has some other attributes and finally ThirdClass that is a derived class from SecondClass and it has some other attributes too. ThirdClass as an association relation ship with Widget class, 1.*.

I used Joined strategy when I wanted to implement a Data Model from the class diagram. so the FirstTable has their Pk in the SecondTable and the SecondTable has its PK in the ThirdTable. As you see Third table should has it's PK in Widget class. And there are some costs whenever I want to Join widget table with third table because I need to fetch Name from First Table.

Is it appropriate that I read Id from FirtTable (Actually it's base class) and put it into Widget table?

I started off using an XML file and a parser as a convenient way to store my data

as such all this works fine. (I use eclipse "validate" option to test it for now)

I was wondering if this was a problem with Eclipse or if the order is actually important.

If the order is important how can I change the DTD to make it work no matter the ordering of he elements?

I can't really change the XML because I already have all the XML files and the parser written (I know I did it the wrong way round lol).

I'm trying to make a simple main window with a menubar. It doesn't work if I try to set up the menubar in the MainWindow initialization but does work if I set it up in some external function. That is, the following does NOT work:

Then the menu is created (I know I don't have any actions hooked up, this is stripped down to show the oddity). I thought it might have to do with being in init but moving it to another class routine, e.g. setup(self), and then calling that after creating the mainWindow doesn't solve the problem.

I seem to be continually baffled by what works and what doesn't in PyQt4. If anyone could point me at some good resources I'd also appreciate it (I've read Rapid GUI Programming but find I'm still lost).

Environment: AngularJS application (using UI Router) that has nested states.

Short version: How do I change the value of a parent-state's dependency from inside a child's controller, such that siblings of the child state, who are also using the dependency will get the new value.

The shop.login state's controller has a function called onLoggedIn that's called once the user has logged in successfully. An object containing user-information is passed to this function. From this point on I want all resolutions of the user dependency to use this value (i.e userObj). Unfortunately, instead of using the value that I've just assigned to $scope.user, it seems that the value that gets passed to the controller of shop.userDetails is the one that was originally resolved when the shop state's controller was created.

Doesn't work, it only repeats the list to stdout, and git checkout seems to receive no input. Ditto for | git checkout HEAD -- and so on.

I've tried this in Windows Command Prompt, in Powershell, and in Git Bash, with the same result each time.

Wireshark won't help you if you have to debug HTTPS requests (unless you can get the encryption keys for both endpoints - see the Wireshark site for details). Firebug and Tamper Data are getting close, but for thorough analysis, I sometimes like to save a recorded session. I'd recommend giving the OWASP Zed Attack Proxy (the successor of Parosproxy, which is no longer actively developed) a try. It is a Java application serving as a http(s) proxy; it provides quite a lot of features and proved to be very helpful to me in the past.

ZAP offers an easy autoconfiguration of Firefox. Bear in mind to do that on a separate (meaning: not for other browsing activities) Firefox profile: In order to intercept https, ZAP will install a new SSL certificate.

Yes, you may use inner_product (dot product) to take the result in very simple way.

Note - there is no need in normalizations, square roots etc. Just some subtractions, multiplications and additions.

In your edit you specify that your helper class is in a seperate assembly. If you want to avoid references and you have control over your app.config files you could put an

using ConfigurationManager along with its property AppSettings. Don't forget to add a reference to System.Configuration in your project. Note that you get the AppSettings of the hosting application. By doing this you need to add a key in your parent application's app.config, or output some error or warning if it's not specified perhaps.

I've tried to attach my own class to a numeric, to alter the output format. This works fine, but after I do a group by the class reverts back to numeric.

I'm afraid the Calls endpoint only takes one "From" number as a filter, you can't pass a list of numbers to it. You might want to return all calls and then filter manually yourself or alternatively loop through the numbers you want to return calls from and make list calls for each of them.

For Microsoft SQL, I'd recommend the books by Kalen Delaney (et al) called "Inside SQL Server". They offer a good insight into the internals of SQL Server, thus allowing readers to educate themselves on why particular statements might be faster than others.

I also like the blogs by Paul Randal and Kimberly Tripp on SQLSkills.com. They are full of solid SQL advice:

I see the join is taking a while can you confirm you have the foreign key in place. Also if you show me the SQL I might be able to help.

Sure it's possible. You'd need to explode the captured pages on the slash / and go from there though.

A component cannot intercept props from its parent because it has no access to its parent, only to its children!

I'm still don't clearly understand what you want to achieve... Does the following code do what you want?

A Network is composed of Nodes that are connected with Fibers. The Network is responsible for making sure that:

Both the Network, the Node and the Fiber are information-rich (they have a name, a date when they were deployed, etc), and it looks to me as if Network is an Aggregate Root (as its the container of both Nodes and Fibers and forces invariants between them).

I'm at this point also sure that Node and Fiber are entities, and that they are also probably Aggregate Roots.

which poses a big problem if my use case is just to edit the location or the name of the Network. In that case I just don't care about fibers and nodes and realistically, it is expected them to be quite possible for their numbers to be on the order of 10k-100k nodes/fibers! How should I approach this issue? Should I separate the definition of a Network (containing fibers and nodes and their invariants) from the rest of the fields?

I've always thought of Aggregate Roots as Entities that have a set of invariants to hold over its attributes, in contrast with Entities that just don't care abouts the state of their attributes (for instance, a Person defined with a name and age wouldn't probably need to have any kind of checking for invalid combinations of name and age).

Following this philosophy, I generally tend to decide whether some domain concept is either a Value, Entity, Value or Event and then if it's an Entity, if it's an Aggregate Root. Is my assumption flawed?

since the return value of show is Prim.String and the first input into trace is Prim.String they should be composable. This is further evidenced by that trace $ show passes the type checking. But instead I get this error:

What am I missing here? Right now my mental model is that trace is very like putStrLn in Haskell, and that one can definitely be composed with show. (putStrLn . show) 5 works.

I have q quick question regarding an Attribute Error regarding a basic Arena battler I am writing for my Intro to Programming Class. Here is the chunk of code that I am having trouble with upon running the program,

Lol, ignore the Name Generator for now, thats an idea Ill try to work out later. The Current problem I am having now is that when I run the program through IDLE i get the following error;

Any Help would be appreciated on the program error, as I have done research and tried to find the answer but all of the other casses of 'str' error involved lists. Thank You in Advance!

So your code doesn't quite look the same, but on the other hand, it's not doing any "magic" either - the code itself shows you when the indented debug ends.

I am using the routemagic library and it works great. Except when I create a new page it doesn't refresh the route map.

in the Config/Route.cs class I have a foreach loop that ties the slug to the ID:

but i still keep getting a 404 page for all new pages unless i refresh IIS..What I would need to do is add a new MapPageRoute everytime I create a new "event" to avoid the 404.

The inheritance list usually gives a list of base classes (see Customizing class creation for more advanced uses), so each item in the list should evaluate to a class object which allows subclassing. Classes without an inheritance list inherit, by default, from the base class object; hence

Add the style import above your existing style, then apply the css rule to whichever element you wish. In this case I applied it to the body. I would also recommend using here strings instead of += as they are far more readable.

It is possible to get index of particular element in list using index() method, following way (borrowed from here):

Is it possible to apply the same principle to nested structures (if not what is the closest most pythonic way)? The result should looks like this:

This does not make much sense to begin with. A Derived should be able to be used anywhere a Base is expected, so you should be able to do

I think you need to look into a different design. It's not clear just what your goal is here, but I'm guessing you might either want Base to be a class template with Fruit as a template parameter, or maybe you need to get rid of the inheritance altogether.

Problem: I don't want it to toggle when I am clicking on the table. Only when I click the button(div). Also, there has to be a selector so that other li's tables doesnt toggle.

I know the problem is: $('table.edititem', >>>this<<<).toggle(); Because the table is not inside the ".button". We need to grab the parent, but how do we do it?

AIR addition to the actionscript 3 language that provide ways to control features from windows, mac, and linux. eg the titlebar and saving files.

Flex is an addition to the actionscript 3 language that provides way to new interrogation features from server technologies like java, php, asp and connection between multiple flash applications and databases.

Flash (CS4) can include AIR code but doesn't include Flex code. the server technology in Flash is limited but exists. Flash includes the GUI that stream lines developing. Like vector based graphics, filters, and components. Also more documentation and examples because it's easier to rewrite classes from Flex into Flash then rewriting Flash code for classes.

Where in Flash you have a button, radio button, dropdown, or menu for every property of a movieclip, image, button. Where in Flex you can write all these properties/options by simply copying pasting, and tweaking the raw code.

I am looking for a Way to be notified on property changed of a dependency property. Similar question was answered here

"If it's a DependencyProperty of a separate class, the easiest way is to bind a value to it, and listen to changes on that value."

Let say I have 100000 rows in ALLOCATION_D table. I want to select first 10 row. Now I want to know how the above statement executes. I don't know but I think it executes in the following way...

Your class's constructor method should be called __construct(), not __constructor():

However, you might want to use pdist to compute it for all combinations of vectors in your matrix at once.

I'm interpreting columns as instances to classify and rows as potential neighbors. This is arbitrary though and you could switch them around.

If have a separate test set, you can compute the distance to the instances in the training set with pdist2:

You can use this distance matrix to knn-classify your vectors as follows. I'll generate some random data to serve as example, which will result in low (around chance level) accuracy. But of course you should plug in your actual data and results will probably be better.

Take a look at the neighborvals and neighborindex matrices and see if they make sense to you. The first is a sorted version of the earlier d matrix, and the latter gives the corresponding instance numbers. Note that the self-distances (on the diagonal in d) have floated to the top. We're not interested in this (always zero), so we'll skip the top row in the next step.

You can compare the assigned classes with the actual classes to get an accuracy score:

removed LEFT in Join over Headerword since it is a not null field in WordRelationship.

You are overwritting the first value in your variable "myAjax" by assigning it a second value. It would be just like doing something like

Here x would hold the value of 7, because that was the last value assigned to it.

will be called when the server you are calling returns a response. When the first call returns myAjax will be holding the value of the second call already, making the first call not display anything. You need to either assign these two variables synchronously (one after the other one has completed), or assign them to different variable names.

I'm currently developing a heavily multi-threaded application, dealing with lots of small data batch to process.

The problem with it is that too many threads are being spawns, which slows down the system considerably. In order to avoid that, I've got a table of Handles which limits the number of concurrent threads. Then I "WaitForMultipleObjects", and when one slot is being freed, I create a new thread, with its own data batch to handle.

Now, I've got as many threads as I want (typically, one per core). Even then, the load incurred by multi-threading is extremely sensible. The reason for this: the data batch is small, so I'm constantly creating new threads.

The first idea I'm currently implementing is simply to regroup jobs into longer serial lists. Therefore, when I'm creating a new thread, it will have 128 or 512 data batch to handle before being terminated. It works well, but somewhat destroys granularity.

I was asked to look for another scenario: if the problem comes from "creating" threads too often, what about "pausing" them, loading data batch and "resuming" the thread?

Unfortunately, I'm not too successful. The problem is: when a thread is in "suspend" mode, "WaitForMultipleObjects" does not detect it as available. In fact, I can't efficiently distinguish between an active and suspended thread.

After much testings, here are my findings concerning Thread Pooling and IO Completion Port, both advised in this post.

Thread Pooling is tested using the older version "QueueUserWorkItem". IO Completion Port requires using CreateIoCompletionPort, GetQueuedCompletionStatus and PostQueuedCompletionStatus;

1) First on performance : Creating many threads is very costly, and both thread pooling and io completion ports are doing a great job to avoid that cost. I am now down to 8-jobs per batch, from an earlier 512-jobs per batch, with no slowdown. This is considerable. Even when going to 1-job per batch, performance impact is less than 5%. Truly remarkable.

From a performance standpoint, QueueUserWorkItem wins, albeit by such a small margin (about 1% better) that it is almost negligible.

2) On usage simplicity : Regarding starting threads : No question, QueueUserWorkItem is by far the easiest to setup. IO Completion port is heavyweight in comparison. Regarding ending threads : Win for IO Completion Port. For some unknown reason, MS provides no function in C to know when all jobs are completed with QueueUserWorkItem. It requires some nasty tricks to successfully implement this basic but critical function. There is no excuse for such a lack of feature.

3) On resource control : Big win for IO Completion Port, which allows to finely tune the number of concurrent threads, while there is no such control with QueueUserWorkItem, which will happily spend all CPU cycles from all available cores. That, in itself, could be a deal breaker for QueueUserWorkItem. Note that newer version of Completion Port seems to allow that control, but are only available on Windows Vista and later.

4) On compatibility : small win for IO Completion Port, which is available since Windows NT4. QueueUserWorkItem only exists since Windows 2000. This is however good enough. Newer version of Completion Port is a no-go for Windows XP.

As can be guessed, I'm pretty much tied between the 2 solutions. They both answer correctly to my needs. For a general situation, I suggest I/O Completion Port, mostly for resource control. On the other hand, QueueUserWorkItem is easier to setup. Quite a pity that it loses most of this simplicity on requiring the programmer to deal alone with end-of-jobs detection.

There are two dependencies usually involved: jmh-core and jmh-generator-annprocess. Their versions should agree. If they don't, then generator may produce the benchmark list in a format that core cannot understand. This most probably is such case.

Try to stick with eclipse, if you're having problems there, it will be worse trying to do things on the command line. The built in tools like log cat and the debugger are of great value.

I think you've got things a bit mixed up here. The server's encoding does not matter to the client, and it shouldn't. That is what RFC 2109 is trying to say here.

The concept of cookies in http is similar to this in real life: Upon paying the entrance fee to a club you get an ink stamp on your wrist. This allows you to leave and reenter the club without paying again. All you have to do is show your wrist to the bouncer. In this real life example, you don't care what it looks like, it might even be invisible in normal light - all that is important is that the bouncer recognises the thing. If you were to wash it off, you'll lose the privilege of reentering the club without paying again.

In HTTP the same thing is happening. The server sets a cookie with the browser. When the browser comes back to the server (read: the next HTTP request), it shows the cookie to the server. The server recognises the cookie, and acts accordingly. Such a cookie could be something as simple as a "WasHereBefore" marker. Again, it's not important that the browser understands what it is. If you delete your cookie, the server will just act as if it has never seen you before, just like the bouncer in that club would if you washed off that ink stamp.

Today, a lot of cookies store just one important piece of information: a session identifier. Everything else is stored server-side and associated with that session identifier. The advantage of this system is that the actual data never leaves the server and as such can be trusted. Everything that is stored client-side can be tampered with and shouldn't be trusted.

Edit: After reading your comment and reading your question yet again, I think I finally understood your situation, and why you're interested in the cookie's actual encoding rather than just leaving it to your programming language: If you have two different software environments on the same server (e.g.: Perl and PHP), you may want to decode a cookie that was set by the other language. In the above example, PHP has to decode the Perl cookie or vice versa.

There is no standard in how data is stored in a cookie. The standard only says that a browser will send the cookie back exactly as it was received. The encoding scheme used is whatever your programming language sees fit.

Going back to the real life example, you now have two bouncers one speaking English, the other speaking Russian. The two will have to agree on one type of ink stamp. More likely than not this will involve at least one of them learning the other's language.

Since the browser behaviour is standardized, you can either imitate one languages encoding scheme in all other languages used on your server, or simply create your own standardized encoding scheme in all languages being used. You may have to use lower level routines, such as PHP's header() instead of higher level routines, such as start_session() to achieve this.

BTW: In the same manner, it is the server side programming language that decides how to store server side session data. You cannot access Perl's CGI::Session by using PHP's $_SESSION array.

Only if you put the "nested select" (THis is referred to as a subquery) in the From Clause:

I do know one is a pass by value, but, from the compiler's pespective, this is a value that is not going to change, so my questions are:

Mostly likely you don't have your app selected in the package explorer tree at the left.

Just click on the top-most item in the tree (ie. "MyFirstApp") and then try running again. Chances are you had "activity_main.xml" selected as it's the default selection when you built your test app.

I have a project open in Visual Studio (it happens to be Enyim.Caching). This assembly wants to be delay-signed. In fact, it desires so strongly to be delay-signed, that I am unable to force Visual studio to compile it without delay signing.

Essentially, the ASP.NET membership providers usually work by setting a client side cookie (also known as an Authentication Ticket) in the client's browser, once the client has successfully authenticated themselves. This cookie is returned to the web server with each subsequent page request, allowing ASP.NET, and thus your code, to determine who the user is, usually with a single line of code like so:

You then should not need to store anything in the Session state. Of course, if you want to store user-specific data in a session variable (i.e. user-data that may not be part of the authentication of a user, perhaps the user's favourite colour etc.) then by all means you can store that in a session variable (after retrieving it from the DB when the user is first authenticated). The session variable could be stored based on the user's name (assuming unique names) and retrieved using code similar to the above which gets the current user's name to access the correct session object.

Using the built-in forms authentication will also allow you to "protect" areas of your website from un-authorized users with simple declarative code that goes in your web.config, for example:

Adding the above to your "main" web.config would ensure that none of your pages are accessible to un-authorized users (though you'd probably never do this in reality - it's just meant as an example). Using the ASP.NET Role Provider in conjunction with the Membership Provider will give you even greater granularity over who can or can't access various sections of your website.

Preventing the user from using the functionality of Screen is bad form (unless you have a shared login which runs your application).

Instead, make your application deal with the use case you've shown by autologout, warning new connecting users and giving them the option to boot the other user, handling multiple users, etc.

No, the current beta VS11 Express edition only supports creating Metro apps. Whether the RTM edition ever will support old style apps requires a crystal ball. I doubt it.

You'll need to use the VS2010 Express edition if you want to create legacy apps.

I am looking for a portable way to find the root directory of a program (in C++). For instance, under Linux, a user could copy code to /opt, add it to the PATH, then execute it:

Now, as a developer of "execution_of_my_special_code", is there a portable programmatical way of finding out that the executable is in /opt/my_special_code?

A second example is on MS Windows: What if my current working directory is on one hard drive (e.g. "C:\") and the executable is placed on another (e.g. "D:\")?

Ultimately, the goal is to read some predefined configuration files that are packaged with the program code without forcing the user to enter the installation directory.

The workaround essentially waits default_socket_timeout and then terminates the while-loop.

It looks like you're somehow sending a pushBetter method call to your view controller which it is apparently not prepared for (according to your code and the error):

Can you to a global search for "pushBetter" and see where it is in your project??

You might want to take a look at what caused the problem in my case and how I solved it here.

As said in the title, I have a scrollview that should be listening for longclicks, but isn't catching any. Nothing happens when I hold the scrollview- no logs, no haptic feedback, & no dialog.

I have an application which let's me drag&drop items from a modified QListWidget on to a modified QLabel using startDrag(), dragEnterEvent(), dropEvent(), etc.

I now want to not only get notified, when the dragging starts but also when it get's interrupted (by pressing ESC or dropping somewhere in the void). (My goal is to uncover a hidden widget I can drop items on which hides again as soon as the drag operation gets interrupted.)

I crawled the docs but find anything promising - has someone accomplished this already?

There is a quite similar question already but it didn't get useful answers and it's two years old - so maybe there are some new trickies introduced by Qt5?

If you think about the overall operation that you are trying to perform, it is really just a Wipe-and-Replace based on what you are passing in. According to your stated rules:

Or, if most of the time the number of items that match exceeds the number of items that will be removed and added, you can take a more targeted approach:

I have a a csv files for insert a products in magento. but there are problem with inserting a products description. In description cell when the code started it stop the insertion of data. Please give me a solution to solve this problem.

I'm starting up an image hosting website which also offers pay per view, for example upload an image and it get 1000 views you get $2.00 something along those lines. The only issue I have is that I want to be able to view the traffic per image and what I.P address were used to view the image.

So someone accesses my site they upload an image using a file form input field it then returns a link e.g - domain.com/image.png what could I add to my code so that some sort of tracking is added to each new image thats uploaded.

my app contains a fragment with a webview and a edit text.i have a navigation drawer with 3 choices and use a switch condition to handle selection,on 3 selections i update the same webview with different html files using the foolowing code ..but my app crashes..

I know I might get a lot of downvotes for this, but I cannot find the information anywhere. I am trying to upload my compiled web application to the internet. I was told that all I need is the dll file which is supposed to go into the bin folder? Is this true or do I need to upload both the dll file and the bin folder?

Also, is there a better way to build so that I dont have to intermix my image, css, and so on into my project folder? Maybe a way to copy the dll file to a bin folder and all my aspx pages?

I got it to work but it seems like I keep duplicating a bunch of files and I know eventually some problem will arise.

Well I believe the default user acls are still working and they are not overrided. The way loopback decides which ACL entry is effective for the request, is by selecting most specific one that appears later. So loopback has defined this entry:

Since it's as specific as it gets, to beat that you have to add this in your model:

There's also another way to remove the default user acls via code but it's not documented.

The CPAN module YAPE::Regex::Explain can be used to parse and explain Perl regexes that you don't understand. Here is the output for your first regex:

You can use the module to parse your second regex as well (I won't dump it here since the explanation will be very long and very redundant.) But if you want to give it a shot, try this:

I am trying to create something where the user can create a table for a topic, but only one topic table and in that topic table other users will be able to add to that topic table.

Here is some code I have that lets users add and displays data from the database.

Since you're using WordPress, the propper way of doing this is to send a JavaScript variable with wp_localize_script in functions.php:

The above will add a JavaScript Data variable that's accessible in all your pages. Then you can use it in the front-end like so:

You said you set a custom image for the UIControlStateHighlighted state. This should disable the default behaviour.

If you still have problems you can disable this effect by setting the adjustsImageWhenHighlighted property to NO and use whatever custom effect you want.

Quick example of drawing the line in the Paint() event, and allowing it to be toggled with a Button:

This approach allows you to change the coords from somewhere else and call Refresh() to update the screen. For more than one line, consider using a List() that holds information about the coords, then iterate over that in the Paint() event.

while creating the button request as a text attribute, we can set the button text

You can pass your array as a JSON string to JavaScript inside the loaded page by calling UIWebView stringByEvaluatingJavascriptFromString:.

First, use a JSON library to encode the contents of your array into a JSON-encoded string. If you use SBJSON then something like this:

(this will work with your simple array of strings. If you have a more complicated array of other objects, they will have to be compatible with the JSON serializer)

In your HTML file you will have to implement a JavaScript function (in this example, "myJavaScriptFunction") that accepts the passed JSON, and decodes it into a Javascript array.

Note that whitespace is important in bash! foo = bar, foo= bar and foo=bar are completely different statements, and all three of them do different things from the other two. Be sure to be cognizant of the differences in copying from this example.

I looked up intent filters and found that they will be used when "Android finds the appropriate component to start by comparing the contents of the intent to the intent filters declared in the manifest file of other apps on the device"(http://developer.android.com/guide/components/intents-filters.html#Building)

which from reading that guide means that this activity can handle an implicit intent with action of main and category of launcher.

However what if i have multiple applications with the same intent filter in the manifest file. I know that some implicit intent will be called with action of main and category of launcher. How does the Android O.S know to choose this application?

Strictly speaking, those declarations are not attributes but namespaces nodes. To get them with XPath, it depends of what version of XPath you use.

For XPath 2, use : fn:in-scope-prefixes and fn:namespace-uri-for-prefix to get the prefix and the associated namespace uri.

In your case, control will go to the while-condition after sorting all the elements.so no need to add do-while.Only set size you want. int i,j,n=4,k,temp; int arr[]={3,5,1,7,9,1,2};

In the project's properties (right-click on project => Properties => Resource) there is a Text File Encoding section.

Did you configure the encoding here? If not, you have two choices : "Inherited from container" (which should be the workspace default, in your case UTF-8) and "Other" which let you choose a specific encoding (ISO-88591)...

I just tested that on one of my projects, closed it and reopened it and the ISO88591 encoding is still configured.

Note that I'm using a plain Eclipse though, not a PDT project. PDT may handle encoding settings differently, but somehow I doubt that (file encoding being a low level functionality it makes sense that all plugins share this behavior).

I'm trying to pass that info variable from the controller, into the directive, through an attribute. It doesn't work because the variable value is initially created from an asynchronous http call, so at the time the directive is created, there is no value.

You can't copy a range with more than one area. You will have to transfer the data over one range at a time. Using Range.Areas you can see that you have multiple areas in multipleRanges.

I had the problem yesterday and after trying out answers in the forum and others but made no headway. My code looked like this.

The code works fine for me, too. As Justin suggested, you're probably overwriting your extracted data.

I can't seem to find an answer to this, maybe I'm not using the correct terminology.

I have a ListView that is editable, I want it so that if a user clicks on Edit and then Update, that the field is updated with the value from another textbox, not the field they are editing.

The reason for this is that I have a Colour Picker that alters the value of a textbox, when they click Update I want this value to be the updated value.

I guess I utilise the ItemUpdating event, but I don't have much in the way of code because I'm pretty lost. I have this so far:

Here is an image that I hope will make what I'm trying to do a little more understandable:

If any one could point me in the right direction of any examples, that would be much appreciated.

The "if" blocks with checkcustomers are exactly used in other methods in this class, so there is a lot of code dublication for same checks. But I cant also directly extract this checksomethings to one single method because they have return values.

Some good ideas to refactor this code? I just modified this code to simplify here, so dont get caught on minor issues in this code(if any), Basically question is how to a extract a piece of code to a method(because it is dublicated on other methods) when there are many returns in that current method.

Created by Dr. Martin Porter, Snowball is a small string processing language designed for creating stemming algorithms for use in Information Retrieval. It was created partially to provide a canonical implementation of Porter's stemming algorithm, and partially to facilitate the creation of stemmers for languages other than English.

A further aim of Porter's was to provide a way of creating and defining stemmers that could readily or automatically be translated into C, Java, or other programming languages. The Snowball compiler translates a Snowball script (a .sbl file) into either a thread-safe ANSI C program or a Java program. For ANSI C, each Snowball script produces a program file and corresponding header file (with .c and .h extensions).

However, if I run Python from the command prompt, I get something similar to the following, with verbose version info for the interpreter all on one line:

Is there a simple way, in a one-line command or via some options to get that same verbose version info line as a string that I could use to populate an environment variable or such?

Your JSX syntax was not correct. I tested this by copying your code into https://babeljs.io/repl/. Specifically, in your User component, you have:

Wanna bind dynamic parameters from PHP PDO. Only getting results for one parameter(@rep=:rep). When second parameter added won't getting any out put

First modify your tableView:cellForRowAtIndexPath: implementation as follows. Then you need to implement the click handler. One way would be in the MyCell class. Another would be to override selectRowAtIndexPath. Without knowing more about what you want (e.g. multiple vs single selection), it's hard to give actual code but here's something.

Thanks alvas for summing it up so nicely, this would help other people too. Moreover I also find any version of the Reuters dataset which has relatively less number of categories. This article here explains it better.

There's not much to go on here but it sounds like you are looking for the Admin Skin functionality. The admin skin is the skin used when you are editing the contents of a module.You can specify the Admin skin in Site Settings. There are definitely cases, and I suspect this is one of them, where it's helpful to have a separate Admin skin.

But generally, I'm not aware of any cases where DotNetNuke will prevent you from doing something you can do outside of DNN. There really are no limitations in it's skinning implementation, as it exposes the full capabilities of ASP.NET. The only caveat is sometimes some additional unwanted markup is added around your content. With DNN6, they are making the rendering of lots of elements cleaner and more semantic.

Something like:

it is possible to rewrite a url and use a proxy server for backgound connection?

An example, I want to use this URL my.domain.org/demo on my proxy server and redirect this into the root directory of my tomcat on another server with proxy_pass my.tomcat.local.

The url must be place my.domain.org/demo and must used the proxy url my.tomcat.local (without any subdomains). Is this hook possible?

Orientation attribute is per activity so you can declare the orientation for only the activity that contains the fragment so that it is in landscape and the rest of the activities will remain as they are.

So you need set orientation in onCreateView of each fragment Plse Check below code:

I've been researching this issue, but I'm not really sure I'm researching the right thing. Until now all my research has been about converting integers to strings etc, but I suspect that I'm barking up the wrong tree. And perhaps my question title is misleading too, but here's my scenario.

I am working on a quiz app that stores all the questions and answers in a .json file in the following format:

The app presents the question with the four possible answer buttons (which have been shuffled using the following code):

Once a button is pressed, the app checks the answer chosen with the following code:

So, what I'd like to do is change the labelQuestion text to present the correct answer if the user was wrong.

All of these attempts have the same outcome - they provide the integer value corresponding to the button with the correct answer. For example, the user is presented with a message like:

I know I must be making a newbie mistake, but any direction would be much appreciated. I'm using the latest version of Xcode / Swift.

To start with it turns out I was editing an old index file so any changes weren't taking affect. Once I realised this I noticed I was including cordova.js twice, once in the head and once below the body, this was causing the following error to occur

I removed this but still couldn't get the plugin to work, I used the CLI to add and remove the plugin several times but still no joy.

After hours of digging I realised I had old redundant plugin code in several different directories, I deleted all plugins from the following directories, along with the android.json file:

This appears to have fixed everything for me so hopefully it'll help someone else!

I'm doing a javascript application for a game, the goal is to make a "build calculator" for a MMORPG. I want to synchronize the view with data already stocked in my application. I searched and tested different framework, and knockout-js appeared to be the best solution for me

The problem is that i don't know how to bind the html to the view in an other object. I don't even know if it's possible. I'd like to do something like that

If not, how can i access to the data inside "SimulatorTool" if the view is separated from the application ?

I 've tried using huge swap files but it doesn't get better. The crash happens long before my swap file is nearly full. I 'm using Fedora 19. Does anyone know anything about this?I think I read something on the internet about how there may be a limit to the memory a single process can allocate.If this is the case ,where can I set it?At least give me a good alternative to valgrind people :P.

You should be able to configure these mappings using either Data Annotations or the Fluent API. Here's a sample of how you might do it using the annotations:

I am trying to unittest a wicket panel with the help of WicketTester and Spock/Mockito.

In this panel, a ModalWindow (confirmation dialog) is show in a good case scenario.

I want to validate this dialog will be shown, so I tried to mock the component, inject it into the panel and test if the show method is called. This won't work, as Wicket throws the following error:

It's not suprising a mock can not call the onDetach method on it's super class.

I've tried stubbing the ModalWindow and using a spy to verify if the show method is called, but the implementation of that method has dependencies / external calls that are hard to mock.

Which way should I approach this problem? Or shouldn't I even try to make this kind of test work?

The columns in the output array from predict_proba are the probabilities of the different labels being predicted by your classifier. In your case, you've built a binary classifier, so the first column modl.predict_proba(X_test)[:,0] is the probability of the label being 0 and the second column modl.predict_proba(X_test)[:,1] is the probability of the label being 1.

I have a function my_function() which I need to run 10 times. Right now all 10 functions are running at the same time (asynchronously?). How can the next execution of the function occur after the previous one has finished?

my_function contains CURL calls and reading/writing to database tables. I wonder if any of these are running asynchronously

Right off hand it looks like you're trying to reference the images and container in your JavaScript before the document is loaded. Try moving your script tag with code after (or right before) the closing </body> tag.

Because the document hasn't fully loaded, the DOM API in JavaScript can't yet access those elements if your JavaScript is in the head.

I'm trying to create a new plugin to package my latest project. I'm trying to have this plugin depend on the maven-dependency-plugin to copy all my projects dependencies.

I've tried a few other names for the goal, like dependency:copy and just copy but they all end with a message saying that the required goal was not found in my plugin. What am I doing wrong?

Secondary to this is where to I provide configuration info for the dependency plugin?

I'm working on a large JavaScript UI module, think about something in the dimension of iScroll. For keeping the thing sane, I split the library up into several logical sub-modules (like: touch interaction, DOM interaction, etc.) that communicate with each other using a simple pubsub system.

Each of these sub-modules has it's own namespace I use for storing variables. To enable several instances of the library running at the same time, the constructor includes some logic to copy every namespace that has been assigned to a 'toCopy' object directly into every new instance.

My problem: I really dislike having to expose the namespace of each sub-module to the rest of the library. Although I'm disciplined enough not to access the namespace of sub-module #1 within a function of sub-module #2, I want it to be technically impossible.

However, as several instances of the UI library have to run at the same time, I cannot put every sub-module inside a closure and define a private namespace inside this closure. This would result in every instance of the library accessing the same sub-module closure and therefore the same namespace.

Also, putting everything inside the constructor instead of into the prototype would create a new set of functions for every new instance, which somehow contradicts the idea of a good library.

My research hasn't brought up any useful patterns for this problem so far, I'm thankful for all suggestions.

I came up with the following extension method that has a special routine for IE6:

Error when I'm trying to add a sha256 hash to a mongoDB with mgo. Other []bytes work fine.

Any idea what the problem might be? I know I could encode the hash as a string but that should not be necessary.

I want to automate clicking a button with id='vote' 3 times with an interval of say 5 seconds with casperjs, for that I have written the code below

But this only working once, what I want to do is to repeat the loop 3 times with a specific interval, since this is a JavaScript ajax post on clicking the vote button and it updates the database, is it doing all 3 clicks at once? What do I have to do to avoid that, and update the database 3 times?

The problem was in drawer_list_item.xml. In Android 2.x the style attributes starting with "?android:attr/" were not available. Removing them fixed the problem.

Is there anything wrong above? What I need to do to make the retry() method work?

I have a fragment with a gridview, which loads say 20 images simultaneously using an adapter. I want to make sure that unfinished Picasso requests terminate gracefully when fragment has disappeared/disposed.

So it turned out, that there was something wrong with the connection. It was created with that code:

With host=192.168.10.100, port=5432, user=turtlebot, password= , dbname=rosdb.
But an empty username doesn't satisfy the usage of PQconnectdb, which, for some parsing-reason, caused it to login to the database "turtlebot". That database unfortunately existed on my server. And there it - of course - didn't get any notifications sent out in the "rosdb"-database and had a good connection.

You can easy add it as static param to url manager rules. I recommend using urls in form /en/controller/action etc, so first parameter is always language. I'm using this approach for long time and works like a charm.

I am attempting to use a select form that has fields populated from an SQL database. There is a table of stores in the database and I used this method to get those distinct fields into the select tool.

The correct store names show up on the select tool but when I submit the form data, the value of the form doesn't get passed properly. Here in the initial page:

I am calling the select name StoreName in the output page but it is not passing the value from the drop down. I need to run a query with that term on the second page so I can pull the relevant data for it. If anyone can see what I'm doing wrong, please advise. Thank you.

It is designed to combine executor and a queue functionality in one. Tasks which completed execution will be available from the completions service via

You can then again use another executor for 3. i.e. fill DB with the results, which you will feed with the results taken from the completionServiceInstance.

Fortunately, you must now use the simpler assignment syntax (which was already available in previous versions of Swift and the same could be done in Objective-C):

I'm trying to make an applescript to make a backup of some files to dropbox. My question was if it was possible to combine multiple IF statmens in my script and if it was possible to make a shorten SET name TO path, like Macintosh HD:Users:svkrzn:Dropbox to ~:Dropbox.

You wouldn't retain ClassA in ClassB, because ClassA already owns ClassB and it's assumed that when ClassA is deallocated, it will take care of cleaning up any references in ClassB.

If you followed the "normal" rules of ownership and retained ClassA when setting the delegate method in ClassB, you'd end up with a retain loop where neither objects would ever be deallocated. Instead, you should be using a weak reference exactly like you are.

Instead of immediately echoing out the responses, try stacking them an array and then outputting the JSON.

I recently upgraded to v4.6 of nservicebus and when I am trying to start locally using services.msc, it is throwing error "services on local system started and stopped". Can't make out what is missing. I can use command line to start the nservicebus using like this:

There's 2 ways you could solve this that don't require your application code to be aware of your container.

The first method, instead replacing the registered instance of UserModel with a new instance, you'd just update the registered instances properties to the new values. This is probably the simplest, if your type is mutable and not overly complex.

This second method would be appropriate if updating the original UserModel instance is undesirable or impossible. Basically, just add a layer of indirection:

Now your service classes can take a constructor parameter of either Changeable<UserModel> or just UserModel depending on whether they need to be able to change the instance or not, with no more direct reference to the container.

sawa's answer is ok, and also you can use a method like this to dynamically create logger for each class.

However, I prefer not to get all classes under a module. In able to create logger for every single class, you can do things as follow.

For classes within a specific module you can write a filter in the logger_name method, for example:

I'd would dinamically set the limit by constantly checking the average load/cpu usage/query time of the database... That way when there are a few users online they can do their work faster. You could set a "maximum" like twitter and if total-load > max-load-you-want maximum=150% and so on...

On one of the service-based sites i've applied this method it actually removed 60% of the spikes after i told the users about the change...

Thanks for your question. It is possible to process multiple refunds (or rebates as we refer to them) against a single transaction. This isn't setup by default on your account, however. You can email your account manager and request that multiple rebates be enabled.

this is a very novice question but I'm trying to understand how boosting certain elements in a document works.

then i needed to boost certain elements in the document more than the others so I did this

the query slowed down considerably, am I doing this correctly? Is there a way to speed it up? I'm currently in the process of doing the boosting when I index the document, but using it in the query that way is best for the way my application runs. Any help is much appreciated

As far as I know you can't build your custom transitions and use them like normal WinRT Transitions, that is, inside a TransitionCollection.

You can't do the above as far as I know. (ignore the fact that I exemplified with a ListView, it applies to everything, I think)

You'll probably have to use a Storyboard that animates both the RenderTransform (TranslateTransform) and the Opacity to achieve your objective.
I think you can still create a Behavior though if you want to make it more reusable.

I know you didn't ask this, and I'm not sure about the problem you are solving, but your code where you manipulate the size of the FormItems outside of the standard lifecycle functions kind of smells funny. Just a suggestion.

If you want a really real-time(around 200ms) response for your search application, for both the first time search query response and further suggested search response, Hadoop is not a good choice, not even Hive, HBase, or even Impala (or Apache Drill, Google Dremel like system).

Hadoop is a batch processing system which is good for write once, read multiple times use cases. And the strength of it is good at scalability and I/O throuput. The trend I saw is that many organizations are using that as a data warehouse for offline data mining and BI analysis purpose as a replacement for data warehosue based on relational databases.

Hive and HBase all provides extra features on top of Hadoop, but neither of those could possibly reach 200ms real time for average complex query workload.

Check the high level view of how 'real-time' each possible solution can really reach, on Apache Drill homepage. CloudEra Impala, or Apache Drill, which borrows the idea from Google Dremel, have the intention to enhance the query speed on top of Hadoop by doing query optimization, column based storage, massive parallelism of I/O. I believe these 2 are still in early stage to achieve the goals they claim. Some initial performance benchmarking result of Impala I found.

If you decide to go with Hadoop or related solution stack, there are possible ways to load data from MySQL to Hadoop using Sqoop or other customized data load applications leveraging Hadoop Distributed File System API. But if you will have new data coming into MySQL time to time, then you need to schedule a job to run periodically to do delta load from MySQL to Hadoop.

On the other hand, the workload to build a Hadoop cluster and find or build suitable data loading tool from MySQL to Hadoop might be a huge workload. Also you need to find a suitable extra layer for runtime data access and build code around that, no mater Impala or other things. To solve your own problem, it's probably better to build your own customized solution, like using in memory cache for hot records with the meta data in your database, along with some index mechanism to quickly locate the data you need for suggested search query calculation. If the memory on one machine cannot hold enough records, a memory cache grid or cluster component comes in handy like Memcached or Reddis, EhCache, etc.

Not easily, the default size of a JLabel, JTextArea etc. is delegated to the "look and feel", this determines the size using the font metrics of the font, the size and the text.

I'd advise you to just accept this, and use a layout manager that deals with the nicely...

i.e. don't assume precise layout, instead use something grid-based with enough free-space so that font size can vary.

If you're still desperate to do this you could override the preferred size of the controls with the following, although this pre-supposes you're using a layout manager that respects these hints.

you're telling the system that whatever work would have been done in the finalizer has already been done, so the finalizer doesn't need to be called. From the .NET docs:

In general, most any Dispose() method should be able to call GC.SupressFinalize(), because it should clean up everything that would be cleand up in the finalizer.

SupressFinalize is just something that provides an optimization that allows the system to not bother queing the object to the finalizer thread. A properly written Dispose()/finalizer should work properly with or without a call to GC.SupressFinalize().

I have two HDs in my Macbook Pro 15 in late 2009. I installed bootcamp and updated to Mavericks. My Windows partition in running Win7 Ultimate. I set the the boot disk in OSX to be my windows partition and now my laptop doesn't recognize me holding down the option key to choose which partition to boot. When windows boots i have to start the on screen keyboard and then close it for my keyboard presses to be recognized. The quote key causes the option and control keys to stick and delete doesn't work at all. I would use the bootcamp panel to switch back but it didn't install. i would really appreciate any help because i'm behind in my web dev projects and don't want to reinstall OSX because i'll lose my data, plus i took out the disc drive for my other HD.

You can do this using scripting variable and using the -v option of SQLCMD utility. A small example from MSDN Documentation

You can then specify the name of the column that you want returned by using the -v option like

If you just want to capture the output from your script file then you can use -o parameter and specify a outfile like

I launched an EC2 instance using the bitnami wordpress ami (i think its an ami?) and everything works great.

Im super excited about this new wordpress project called VersionPress, link below.

I managed to install git and get a tick in that box. Now I need to satisfy the plugin's requirements for write permission on several folders.

I've been reading up on chmod, and checking out what permission are currently in place using ssh, but can not, for the life of me, make sense of it.

If we take for example the plugins own folder /versionpress, I can navigate to it and see the current permissions using ls:

So I'm like ok, I suppose I'd better give group write permissions. But, no version of the chmod command I write will execute and even then, it's only one of the folders that I need to change.

As a next step I tried to change rights on /wordpress dir. This was initially unsuccessful until I applied command with Sudo.

Error msg: VersionPress needs write access in the site root, its nested directories and the system temp directory. Please update the permissions.

Anyone experienced this, got VersionPres up and running on EC2 or with any advice to move me forward?

I have a Haskell project that aims to create some C++ bindings. I've written the C wrappers and compiled them into a stand-alone statically linked library.

I'd like to write the Haskell bindings to link statically to the C wrappers so that I don't have to distribute the C wrappers separately but I can't seem to get it working and would appreciate some help.

I specify the C library as an extra library but my cabal build step doesn't seem to add it to compile command.

The C library is added in Setup.hs not in the Cabal file because that's how I have it my real project which builds the C library using "make" through Cabal just before the build stepf. I have verified that at the build step the extraLibs part of BuildInfo contains the library name and extraLibDirs contains the right directory.

Unfortunately neither the compilation nor the linking step uses the C library. There are no other warnings or errors.

index.php or index.html should be the default files loaded by your server when visiting a site, not home.html. Try clearing your cache. If that doesn't help it could be an issue in httpd.conf - but that sounds kind of extreme in this scenario.

You can also look into using mod_rewrite in your .htaccess file so the redirect happens at the server level

I am trying to implement an editable table viewer in Eclipse SWT. I think I've done everything ok until now, problem is the table is not editable - nothing happens if I click on any row.

Like Christian Conkle hinted at, we can determine if a type has an Integral or Floating instance using more advanced type system features. We will try to determine if the second argument has an Integral instance. Along the way we will use a host of language extensions, and still fall a bit short of our goal. I'll introduce the following language extensions where they are used

Convert Integral context to type

To begin with we will make a class that will try to capture information from the context of a type (whether there's an Integral instance) and convert it into a type which we can match on. This requires the FunctionalDependencies extension to say that the flag can be uniquely determined from the type a. It also requires MultiParamTypeClasses.

We'll make two types to use for the flag type to represent when a type does (HTrue) or doesn't (HFalse) have an Integral instance. This uses the EmptyDataDecls extension.

We'll provide a default - when there isn't an IsIntegral instance for a that forces flag to be something other than HFalse we provide an instance that says it's HFalse. This requires the TypeFamilies, FlexibleInstances, and UndecidableInstances extensions.

What we'd really like to do is say that every a with an Integral a instance has an IsIntegral a HTrue instance. Unfortunately, if we add an instance (Integral a) => IsIntegral a HTrue instance we will be in the same situation Christian described. This second instance will be used by preference, and when the Integral constraint is encountered it will be added to the context with no backtracking. Instead we will need to list all the Integral types ourselves. This is where we fall short of our goal. (I'm skipping the base Integral types from System.Posix.Types since they aren't defined equally on all platforms).

Matching on IsIntegral

Our end goal is to be able to provide appropriate instances for the following class

We want to match on types to choose which code to use. We'll make a class with an extra type to hold the flag for whether b is an Integral type. The extra argument to pow' lets type inference choose the correct pow' to use.

Now we'll write two instances, one for when b is Integral and one for when it isn't. When b isn't Integral, we can only provide an instance when a and b are the same.

Now, whenever we can determine if b is Integral with IsIntegral and can provide a Power' instance for that result, we can provide the Power instance which was our goal. This requires the ScopedTypeVariables extension to get the correct type for the extra argument to pow'

You can read another explanation of how to use FunctionalDependencies or TypeFamilies to avoid overlap in overlapping instances in the Advanced Overlap article on HaskellWiki.

I looked at the cookies present on the browser and found that both the JSESSION IDs are present. The only difference is in the domain scope of both the JSESSION IDs. App1 application has domain scope of say abc.com whereas App2 has app2.abc.com

I tried changing the name of the JSESSION ID cookie of App2 but the application did not work with the renamed JSESSION cookie.

I'm working on a C# windows application but I'd like to create a website to be hosted on the same machine that could provide monitoring, other people on the network would be able to login and see the state of certain variables, maybe trigger methods to turn things on and off. I'm looking for a point in the right direction as to how I'd go about doing this?

Before using the "prompt" module, I used the ReadLine interface; sadly I had the same problem. However, the fix was simple:

Inside the categories page I have some sorting and pages options such as sorting by latests and lower price. Also, I have a pages navigation system

The problem is when the request is happening inside the page the $_GET[] doesn't show the variables I need. However it shows in the URL as

The $_GET variable only shows the id of the category which is in our case now = 23 and ignored the page number which is in the url.

I would like to make an ipywidget floatslider, but passing it a list of values, rather than a range and step. Is there a way to do this, or is making a dropdown widget the only option?

In base class, create abstract virtual method that returns some kind of "ID". (string, int, enum, whatever).

In "save" method, write ID first, for all classes. You could embed ID writing into base class, so derived classes won't override this behavior.

QSharedPointer is smart pointer class from Qt 4, roughly equivalent to std::shared_ptr. Use either std::shared_ptr or boost::shared_ptr instead of QSharedPointer in your code.

I'm testing something in Oracle and populated a table with some sample data, but in the process I accidentally loaded duplicate records, so now I can't create a primary key using some of the columns.

The answer is pretty simple, clearing the FLAG_FULLSCREEN flag is all thats necessary:

If the parts to remove are always the same you can use str_replace() function passing as serach value an array with both parts you want to remove

and in the client, to process the two different requests in some stateful manner(the receiver is supposed to know that ).

Instead, can you encapsulate the two requests in one(one request with two parameters). Something like

I don't recognize the framework which you are using, but in JAX-RS the method will looks something like this

Here is a nasty, hacky, quick-fix solution which will stop the nasty cropping by resizing Swing's own icons to 80%.

You might want to first check whether this is actually required - Windows 8/10 defaults to 125% but some people will switch it back to 100%. I haven't found an elegant way to do this, but something along these lines will give you an idea:

It could be that you can fit 2 rows of 2000 doubles into the cache. Which is slighly less than the 32kb L1 cache. (while leaving room other necessary things)

But when you bump it up to 2048, it uses the entire cache (and you spill some because you need room for other things)

Assuming the cache policy is LRU, spilling the cache just a tiny bit will cause the entire row to be repeatedly flushed and reloaded into the L1 cache.

The other possibility is cache associativity due to the power-of-two. Though I think that processor is 2-way L1 associative so I don't think it matters in this case. (but I'll throw the idea out there anyway)

Possible Explanation 2: Conflict cache misses due to super-alignment on the L2 cache.

Your B array is being iterated on the column. So the access is strided. Your total data size is 2k x 2k which is about 32 MB per matrix. That's much larger than your L2 cache.

When the data is not aligned perfectly, you will have decent spatial locality on B. Although you are hopping rows and only using one element per cacheline, the cacheline stays in the L2 cache to be reused by the next iteration of the middle loop.

However, when the data is aligned perfectly (2048), these hops will all land on the same "cache way" and will far exceed your L2 cache associativity. Therefore, the accessed cache lines of B will not stay in cache for the next iteration. Instead, they will need to be pulled in all the way from ram.

I'm guessing that it has to do with using a keyword as a function name. I tried defining a function print() in a module just now for testing and got the same sort of error. Try changing the name of this function slightly and see if it fixes the problem.

If I have understood the question correctly I think you just need a CASE statement in the SELECT e.g.

FYI, I was able to customize the watch face, using the extension code you provided. No problem there.

If you notice the bundle id in the crash log error, the system is reporting a problem with the watchkit app (which contains the watchkit extension).

You'll need to track down what's wrong with the watchkit bundle. The first place to start would be the Xcode watchkit app build target log. If there are no errors or warnings there, check the iPhone and Apple Watch console logs.

If that doesn't point you to the problem, check the Info.plist to make sure those values are valid, and the required keys are present. Also check the watchkit app target build settings.

You should be able to use the Version Editor to compare the Xcode project against its initial commit, to see if something was inadvertently changed or deleted.

easily done, you just need to set the display to inline-block for those two iframes.

iframes are somewhat frowned upon. You might like to consider using divs with ajax instead, utilizing the jquery $.load function to load whatever you like into them. You can read up on that here.

Is the link from a different domain? Browsers may restrict access to any information about what a user has open in other windows or frames if it's on another site as a security precaution.

I am a Silverlight 4 developer getting started with WPF4. In Silverlight 4, there is option available in menu "Edit in Blend" when you right click on any xaml file. Why is this option not available in WPF4?

It was worked earlier - I just put a new OS and trying the same under C;\server for generic setup so that I can make use of it in every windows 64 bit system with same directory structure.

A question becomes stupid when you know the answer like you remember a-z. So no question is stupid generally.

The problem is that you're not escaping the special characters in the text, such as the / delimiter.

The easiest solution is to pick a different delimiter and to specify only a part of the string, for instance

(untested) may do the job. (The .*? construct picks the shortest match; I don't know how to do that in sed.)

It work's OK, but If I have for example file1.exe, file2.exe, file3.exe files code anyway prints "App cannot find these files - file1.exe, file2.exe, file3.exe, file4.exe". How to make it print only needed file which not exists? Example: if exists file1.exe, file3.exe, it must print: App cannot find these files - file2.exe, file4.exe Thanks in advance

I am trying to create a function that creates an element and takes the parameter of element (an object).

The only problem is I want to append the element to the element that called the function. For example:

My question is how do I append it to the element that called the function, in this case, the ul list

You can apply the Holo theme using the HoloEverywhere library. I use it in all my apps, and it works very well.

You have to add it as a library project to use it. If you use Git, you can add it as a submodule.

I am having an issue opening a thick-box with anchor tags appended to a div at runtime.The anchor tag contains the thick-box css and the href,that is required to open up a thickbox.However,its not opening up the required page in a thickbox. All it does is,open up the page in a new page. However,when i crate a hard coded anchor with the required thickbox stuff,it opens up fine.The only issue is ,it doesn't do the same when it is generated at runtime .

Doesn't Jquery understand anchor tags with thickbox property append at runtime ?

You can't send through the email submitted on the form, since you aren't authorized to use that email. You either have to use an email you control or the user's email by connecting to their Google account. http://code.google.com/appengine/docs/python/mail/sendingmail.html This page says which email you can use to send emails from, just scroll down right after the first code block.

I have a dynamically generated html table that adds rows based on the record that is displayed. I'm adding a column that will contain a dropdown. I used ng-options for it, however every time I change one record, the rest are also updated. Tried changing it to ng-repeat and get the same result. See code below:

I know that these two are currently displaying two different things (one a concatenated set of values, the other juts one). But my main interest is to figure out how to have each <td> have its own dropdown without affecting the rest of the rows.

I want to save that delta to count the days between all to and from days in the from-to pairs I have in the 2 dimensional array, I just need the workdays.

This error is commonly because of a DLL version mismatch. Try deleting your bin folder and rebuilding the application.

I am able to return the multi-part identifier alert for each of the two entries highlighted.

The alias tpc is referenced correctly, but the right side of each expression will not. I have substituted the alias' from the FROM clause, but they are out of scope here.

I have been trying to sort this for some time. I believe there is a namespace issue, but do not know how to reference the changes required.

I run across this issue regularly, but have always been able to resolve it with a search. I can find nothing that appears to clear this up.

No, you are misunderstanding how that method works. componentsSeparatedByString: doesn't use the individual characters in the passed string, it uses the entire string. Your separator is the three-character sequence [,]. A string like @"pecan[,]pie" uses this separator, but @"1[0,5]" does not. The similar method componentsSeparatedByCharactersInSet: will do what you are expecting:

If you want to pull digits out of strings and get their numerical values, you may want to look at NSScanner.

in ALL browsers, the browser will make padding and margin between all the things. to remove that and control the page yourself add this add the first line of your css:

auto makes all the things (except text and images) at the center of your page.

I created a Java application in NetBeans. That Java application contains a GUI and some external Jars.

In the dist folder I can see a Jar file and a folder called lib where are the jars I use in the project. If I execute the Jar file the application works as expected. If I change the name of the lib folder the application does not work (meaning that the Jar is using the correct files). But when I copy the dist folder to a different machine (with the same Java version) the application does not work as expected. The user interface is shown but the functionalities does not work (the functionalities are in the external Jars i mentioned in the beginning). Can anyone help?

(p.s. Be sure you are using a recent version of c3p0. These settings are new-ish.)

I have a small issue regarding a dataset I am using. Suppose I have a dataset called mergedData2 defined using those command lines from a subset of mergedData:

Now, suppose I want to take the average of each of the measurements per volunteer_identifier and type_of_experiment. For this, I used a combination of split and lapply:

As average_activities is a list, I converted it into a data frame and transposed this data frame to keep the same format as mergedData and mergedData2. The problem now is the following: when I call names(average_dataset), it returns NULL !! But, more strangely, when I do:head(average_dataset) ; it returns :

This is just a small sample of the output, to say that the names of the variables are there. So why names(average_dataset) returns NULL ?

My duty is to get this average_dataset (which is a dataset which contains the average value for each physical quantity (column 3 and onwards) for each volunteer and type of experiment (e.g 1 1 mean1 mean2 mean3...mean68 2 1 mean1 mean2 mean3...mean68, etc)

After this I will have to export it as a txt file (so I think using write.table with row.names=F, and col.names=T). Note that for now, if I do this and import the dataset generated using read.table, I don't recover the names of the columns of the dataset; even while specifying col.names=T.

If speaking about x86 architecture when an operating system has nothing to do it can use HLT instruction. HLT instruction stops the CPU till next interrupt. See http://en.m.wikipedia.org/wiki/HLT for details.

When I send an sql query with function query of "request.service.mssql" object, the result function is called twice...

I don't understand because my sql query is an "update" and the result is empty (I do not have multiple lines of results)

For example, I have a function that send an email with a new password. The email is sent twice... I found a temp solution with an index but it's not very clean.

If you just want to display the form at the end of the page, go to the form advance settings and click on "available as block"

Then on the block sections, add it to the "main content section" and configute the block.
Under Show block on specific pages, write the pages you want it to appear.

I'm trying to implement a function to compute the cotangents of vectors (the mathematical ones) via the standard formula:

A colleague told me that calculating 1/|a x b| is not the best thing to give a computer to calculate. Another alternative coming to my head is first calculating the angle and than using cotan functions for radians angles.

What would be the method of choice here? (Is there maybe another one, other than the mentioned ones)

I'm running into the same issue on Xamarin.android. Here's what the documentation says.

Yes, you can send a GET request with no query string. In fact, whenever you hit a webpage using with your browser, you are sending a GET request, e.g. when you type http://google.com in the address bar and hit enter, your browser sends GET request to the URI and google server returns its page.

Seems like if str is empty, you're not sending the request at all. Am I correct?

I have two machines. One machine is a client and the other is a server running JBoss. I have no trouble having the client make requests and the server respond to those requests. However, for a new project that I need to do I have to reverse the roles. I have to implement a push model, so the server will need to make requests from the client. Specifically I need the server to be able to ask the client for files in a directory, copy files from the server to the client, and run programs on the client. I'd like to do this without adding a psedo server on the client (a small daemon process).

EDIT: So it would appear that I have to set up a server on the client machine to do what I need because I need to have the server push to the client while the client is not running the Java process (but the machine is on). With that in mind, what's the lightest weight Java server?

This will prevent your crash from accessing "objectForKey" (doesNotRecognizeSelector).

I am getting below exception while deploying my application on WebSphere Application Server 8.5.5

java.lang.RuntimeException: SRVE8111E: The application, MyEAR, is trying to modify a cookie which matches a pattern in the restricted programmatic session cookies list [domain=*, name=JSESSIONID, path=/].

I found that if I remove below entry from my web.xml [session-config], then no error is shown with deployment and every things works fine.

The same ear is able to deploy and run perfectly with JBOSS and WebLogic server.

Please let me know what configuration change I have to do in which xml file to overcome this issue.

My application has application.xml, jboss-deployment-structure.xml and weblogic-application.xml.

I'm using InAppSettingsKit with localized text with no problems. Two things I can think of that you could check: are your Root.strings files located in the correct subdirectories of Settings.bundle (en.lproj and fr.lproj for English and French?

Is there a "Strings Filename" entry in your Root.plist? It should simply contain a string with value "Root"

It looks like you're source code and binary are out of sync, ie. you're debugging a DLL/EXE that has been compiled with different version of the source code.

During debug activate the Debug->Windows->Modules window and check that the DLL/EXE you're debugging is the same as the one you've been compiling with your source code (check date/times, symbol files etc.).

I created a new developer account and I am having a problem authenticating with the REST API.

I've coded an app which uses Switch as a toggler. When I run it on ICS I have no problems, but when I run it on gingerbread it crashes:

I have a short question that in the work function, should i use delete[] operator? since when work function is over, p will be destroyed, which is wrong or right ? (My English is bad, i am sorry).

Hey, I was wondering if someone knows a good way to scale an image while maintaining aspect ratio, and then center it with respect to a specified fixed crop area.

The first part is straight forward (resizing while maintaining ratio), just need help with the second part.

i used this code and I am having problem in the very basic step of how to use operator. Moreover I am even having problem taking more then 1 digit. If you please just add up the missing statements which would help me out. In the given code I have removed those steps that created problems in actionPerformed function

Additionally, I figured that I was making another mistake. I forgot to enclose btnContactList in double quotes. After debugging in Internet explorer, I found that out. Secondly, as @Oleg suggested that the jsonReader attribute is required. Probably because of the version of jqGrid that I am using.

I need to get the keys ordered by the values. For example, getting c,b,a values: I will work on them in this order; first I need to use c to do other operations then b then a.

I used this to get the max value but I need all the values and use them in order mayor to minor:

edit: i need to get c,b,a sorted on this order and without using a b c , because c has the highest c1 value etc.. ok that works to sort a dict in reverse way but lets say i have this data:

second column is a prior, all this is stored into a dictionary the main keys are 1000,1001,1002,1003, the rest are values, i want to get 1000,1003,1002,1001 (this last have same prior) on this order,

UIViewContentMode seems to reference an Integer so I am not sure on this warning:

How can I get rid of this warning it seems to be incorrect? Is the NSLog in the exception correct?

You could also use TO_CHAR, but use it only to display, for any number arithmetic you should leave the number as it is.

The other option that you have, depending on what you're trying to do, is to host the CLR in your application which allows you to more tightly integrate the C# code than is possible by going through COM. You can read an overview of doing this in this MSDN Magazine article.

Simply because b variable is initialized inside the function print.. and c variable is initialised on the global scope. so at this line:

you trying to get the value of b variable but ur not calling the function print..

because b didn`t change as the function has not yet been called .. but c has changed by the if statement which lies on the global scope.

I am using PouchDB with an Ionic APP, I debug it using Chrome and looking into the console. I would like to inspect the device pouchDB database like I do in chrome with the localhost version with PouchDB Inspector

Is there a way to do this? I do not see anything when I enter the PouchDB Inspector while in Chrome -> Inspect Remote Devices

I am working on CLR stored procedure using VS2010. I need to generate standalone deployment script to install this procedure at customer servers. Now I am using Visual Studio which generate such script when I press F5 and try to debug SP on DB server. This script is placed at bin\Debug\MyStoredProcedure.sql file. It looks like this:

I am wondering, is it possible to generate such script without Visual Studio? For example, what if I build solution with MSBuild and then generate this script with some tool? I believe, that if I read assembly as byte array and then serialize it to hex string and insert into script template - it could work, but maybe there is some easier standard solution?

I add some sub-item under MANUALS main item. What can I do to make its sub-menu hide and show when I click on its parent main item?

I try to write some jQuery code but right now only can hide the item but cannot let it show again. Is something wrong on my jQuery code?

so you should add 'testserver' in django sites.site model as a base url. maximum recursion depth exceed because django client did'nt find 'testserver' as a domain in sites.site

Your first call to hadoop fs -ls is a relative directory listing, for the current user typically rooted in a directory called /user/${user.name} in HDFS. So your hadoop fs -ls command is listing files / directories relative to this location - in your case /user/Li/

You should be able to assert this by running a aboolute listing and confirm the contents / output match: hadoop fs -ls /user/Li/

As these files are in HDFS, you will not be able to find them on the local filesystem - they are distributed across your cluster nodes as blocks (for real files), and metadata entries (for files and directories) in the NameNode.

Steve, I had to migrate my old application the way around, that is PgSQL->MySQL. I must say, you should consider yourself lucky ;-) Common gotchas are:

You'll find the $locationChangeStart is an event you can listen for to detect for a route change.

The distinction between user clicking back or changing the url etc will not make a difference. As browsers don't reload any resources when you alter the url past the # it's all still contained in your angular logic. This means all these methods should trigger the $locationChangeStart event.

@Jon pointed out that the $route service will definitely be of use to you. the .reload() method will prevent the route change from completing but there is much more you can do with the $route service if you look into it - see documentation.

if _WIN32_WINNT > 0x0501

//#error This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended.

I know it isnt the right way to do [ editing a file shipped by the IDE ] but did since it may be due to Improper installation.

Add these four lines to above code, so that the right side gap is also removed from support action bar.

Application servers exposes business logic to a client. So its like application server comprises of a set of methods(not necessarily though, can even be a networked computer allowing many to run software on it) to perform business logic. So it will simply output the desired results, not HTML content. (similar to a method call). So it is not strictly HTTP based.

But web servers passes HTML content to web browsers (Strictly HTTP based). Web servers were capable of handling only the static web resources, but the emergence of server side scripting helped web servers to handle dynamic contents as well. Where web server takes the request and directs it to the script (PHP, JSP, CGI scripts, etc.) to CREATE HTML content to be sent to the client. Then web server knows how to send them back to client. BECAUSE that's what a web server really knows.

Having said that, nowadays developers use both of these together. Where web server takes the request and then calls a script to create the HTML, BUT script will again call an application server LOGIC (e.g. Retrieve transaction details) to fill the HTML content.

Therefore .... We can fairly safely say that in nowadays, in most of the cases, web servers are used as a subset of application servers. BUT theatrically it is NOT the case.

I'm not sure to what limitations the author of the python tutorial was referring, but I would guess it has in part to do with the way that method / attribute lookup is implemented in python (the "method resolution order" or MRO). Python uses the C3 superclass linearization mechanism; this is to deal with what is termed to be "The Diamond Problem".

Once you've introduced multiple inheritance into your class hierarchy, any given class doesn't have a single potential class that it inherits from, it only has "the next class in the MRO", even for classes that expect that they inherit from some class in particular.

For example, if class A(object), class B(A), class C(A), and class D(B, C), then the MRO for class D is D->B->C->A. Class B might have been written, probably was, thinking that it descends from A, and when it calls super() on itself, it will get a method on A. But this is no longer true; when B calls super(), it will get a method on C instead, if it exists.

If you change method signatures in overridden methods this can be a problem. Class B, expecting the signature of a method from class A when it calls super, instead gets a method from C, which might not have that signature (and might or might not not implement the desired behavior, from class B's point of view).

In this code sample, classes B and C have reasonably extended A, and changed their __init__ signatures, but call their expected superclass signature correctly. But when you make D like that, the effective "superclass" of B becomes C instead of A. When it calls super, things blow up:

This same sort of thing could happen for other methods as well (if they call super()), and the "diamond" doesn't have to only appear at the root of the class hierarchy.

Based on your example, you are trying to delete all files present within some folder. Instead of iterating over all the files of the folder, and delete each file individually, the better way is to use shutil.rmtree(). It will recursively delete all the files for the given path (similar to rm -r /path/to/folder in unix).

I am getting the error below (worker.log) when submitting a topology to Storm 1.0.1 (despite the error, the topology does get submitted and appears in the Storm UI):

Further messages seem to suggest that the worker fails to start and supervisor.log then starts logging INFO message "{id of worker process} still hasn't started" multiple times.

My code is supposed to continuously loop until "stop" is entered as employee name. A problem I am having is that once it does the calculation for the first employee's hours and rate, it will skip over the prompt for employee name again. Why? (The code is in 2 separate classes, btw) Please help. Here is my code:

I have a .NET Application that runs on a server with 16 COM ports, about 11 of which are currently connected to various devices, some RS485, many RS-232. (Diagram here: http://blog.abodit.com/2010/03/home-automation-block-diagram/). Most of these devices are running just 9600 baud, and most don't have very tight timing requirements. I have a thread per device handling receiving and while it runs at normal thread priority, all other non-communication threads run at a lower priority (as you should do for most background tasks anyway). I have had no issues with this setup. And, BTW it also plays music on three sound cards at the same time using high-priority threads from managed code and 1second DSound buffers, all without glitching.

So how tight are your latency requirements, what baud rate and how many serial ports are you trying to serve? The buffer on your UART at most normal baud rates is more than sufficient for garbage collection and much more to delay taking the next byte off it.

GC is not as evil as it is made out to be. On a properly prioritized threaded system with good management of object sizes and lifetimes and sufficient buffering (UARTS/Sound buffers etc.) it can perform very well. Microsoft is also continuously improving it and the .NET Framework 4 now provides background garbage collection. This feature replaces concurrent garbage collection in previous versions and provides better performance. See MSDN.

I created a branch from my SVN trunk. In the branch, another developer deleted a directory, but then readded it with the same files. When I merged the changes from the branch back into the trunk (using TortoiseSVN), this directory had a "replace into" message. I unfortunately merged those in (none of these files in the branch had changed, but since it was deleted and added, it showed up as a change). Now, the history for those files only goes back to the time it was readded in the branch. I have the old history in a tag from before the merge, but it is a pain to have to go to that to get the history.

Is there a way to update the files to get the history back into the trunk? Even if I merge the tag into the trunk, would it actually update the full history? I have a feeling it would just merge any file changes, not the history.

I have a node.js application running on port 5000, where I use passport.js as authorization. I authorize users from a post request, where I use a custom callback:

This works fine, but when I develop local I have a frontend Angular2 application, which runs on a different port (4200), so in my development I am not possible to get the authorized user: req.user is undefined. I use express-session to store the authorized user.

Does anyone have a good and simple solution for this issue? Again it's only in development I have this problem.

I know that such type of questions exist in SF but they are very specific, I need a generic suggestion. I need a feature for uploading user files which could be of size more that 1 GB. This feature will be an add-on to the existing file-upload feature present in the application which caters to smaller files. Now, here are some of the options

Moreover, I've to make sure that this upload process don't hamper the task of other users or in other words don't eat up other user's b/w. Any mechanisms which can be done at n/w level to throttle such processes?

Ultimately customer wanted to have FTP as an option. But I think the answer with handling files programmatically is also cool.

Okay - I'm definitely learning a lot about Mercurial and version control systems more and more as I use them, but I'm really confused about why my local copies of one of my repositories (call it project-alpha) on three machines I use (machine 1, machine 2, and machine 3) are different. Notably, they do not share the same tip.

I was hoping somebody could explain this to me, and in addition offer some explanation as to how I may avoid having to "merge" branches altogether (which is how this complication came up in the first place). It would be awesome if somebody could provide an example of how certain circumstances will force me to "merge" on one machine, whereas on another it is perfectly fine without.

commands for each of the three machines I am using (but only where they begin to differ, since it's a long project I'm working on).

Let me first start off by saying that I understand there are some differences simply due to the fact that some changes were pushed on some machines and pulled on others. Machine 1 and 2 are the primary ones I use, and it clearly doesn't differ too much. What I'm concerned about is Machine 3, which currently has 3 heads, and an additional changeset (89 instead of 88). I'm a bit confused as to what is happening, how I can fix this, and I would appreciate knowing exactly what I did to cause this so that I may avoid this type of behavior next time. Thanks in advance!

I would like to regularly check the status of the logged in user. My method is as follows but I am unsure as to whether this is the best way to go about it.

I am aware of the 'subscribe' functions but I am not really sure what they are for. If these are suitable then I will consider using them but I need to have a clearer picture of what they do and how often. I have read the documentation and they simply say that it attaches a handler. This is not very detailed!! What does it attach a handler to!!??

Additionally, if I want to call FB.getLoginStatus outside of the 'fbAsyncInit' function, is this possible?

I have implemented the google plus api on development server and it works fine. I used the same code on production server. But after requesting the permission it takes a long time to return to my site and login.

I have a Problem with my Sony SmartWatch App. I've developed a widget with control, but after the App is installed by users on the device the scheduled refresh task of the widget starts automatically. This means the refresh task is running all the time, even if the user did not turn on SmartWatch Display or start the widget. This drains the battery. If I go to the widget screen and then turn the display from off, the scheduled Task stops like expected. But if I don't do this the task is running and running and running.... How can I detect if the Display is on and the widget is running?

P.S.: It makes no difference if the "Activate Widget" preference is checked or not....

EDIT: I've found out that the widget sourcecode does not fire if I uncheck the "Display as Widget" Checkbox in preferences. This means if the refresh schedule is running and I uncheck this box, the onDestroy is never called and so the cancel schedule also not....

So I am trying to get to grips with someone's code (and cannot contact them) and I do not understand why they do this. They call a function in main like this:

There does not seem to be any ultimate definition of the LOG_AddFunction function and I do not understand why the code calls it. Can someone shed some light on this please?

I believe the problem is that with a key of lang.mail.layout.greeting, Freemarker treats each part between the .s as a hash i.e. a container variable that can have subvariables. So it attempts to get the object referenced by lang from the data-model and then attempts to get the variable referenced by mail from lang. In your case, however, there is no such object, hence the error.

I know there are a lot of question already on this subject, but I needed more specific information. So here goes:

I have an application witch run on local admin account with MFC and user interface. When i change logon windows 7 cession, Application failed.

How can i keep the application alive when changing windows cession?
Thanks for your help!

The slot locator is shared in the class. It will be allocated somehow in the class object. The DEFCLASS form creates this class object. Thus the slot locator usually will be initialized when the class object is created and initialized. Way before the first instance of that class is created.

As you see SHARED-INITIALIZE is called on the class object, which then initializes the shared slots.

I also don't think calling error like this should be done in user code. You might find a better way to check for missing initargs.

Is there away to specify the groupby call to use the group name in the apply lambda function.

For instance, if I iterate through groups I can get the group key via the following tuple decomposition:

But keep in mind, that child with provided key should exist in list, otherwise you will get an exception. I think better to find child first, and then if child exist, get its value:

You need to put things together differently to accomplish your goal. You can't just replace ++ with :. Try this:

toListPlus t xs should produce toList t ++ xs, but implemented with recursive calls to toListPlus, not using ++ or toList. Let's work through it. The base case is easy:

The recursive case isn't too bad either. We want to convert the left subtree to a list, sticking other stuff on after:

What comes after? The root, and then the result of converting the right subtree, and then whatever gets tacked on:

This function uses an implicit stack to keep track of the remaining work. This is probably the most efficient way to do it. If you wanted, you could use a zipper-style representation to make the stack explicit.

How does this solution relate to the one leftaroundabout described? Well, they're actually the same. We can see that by shifting the list argument over:

First, 'flatten' the list using a generator expression: (item for sublist in combs for item in sublist).

Then, iterate over the flattened list. For each item, you either add an entry to the dict (if it doesn't already exist), or add one to the value.

This technique assumes all the elements of the sublists are hashable and can be used as keys.

Well, question is not fresh, but this situation may still become a piece of pain. You may use toJSON or toObject method to get normal, iterable object. Just like this:

You can use a CursorLoader for this. It assumes also that you have a ContentProvider as your data source for the application, which I will not discuss here but you can learn about them in this post if you want.

To implement the LoaderManager just override the three required methods. One is used to setup your Cursor, one will feed the results to your Adapter. From then on, assuming your ContentProvider properly notifies any URIs of changes, you will notice those changes in the Adapter. Here is a snippet of the Loader code:

I learned much of this from a Udacity course that teaches you a lot about Android from the bottom up, and if you are looking for a complete overview I think it is very much worth your time.

Well I ran into the same problem few months back and the way I fixed this was by presenting mmvc as modal view controller. Please try replacing your else with something like this:

Also, there seem to be an issue with your authentication. Your method should use new mechanism for player authentication like:

You actually need to include a fragment (NOT the Relative Layout) to your layout like so:

I don't have an answer for safe bool, but I can do this bit. It's because a conversion sequence can include at most 1 user-defined conversion (13.3.3.1.2).

As for why that is - I think someone decided that it would be too hard to figure out implicit conversions if they could have arbitrarily many user-defined conversions. The difficulty it introduces is that you can't write a class with a conversion, that "behaves like built-in types". If you write a class which, used idiomatically, "spends" the one user-defined conversion, then users of that class don't have it to "spend".

Not that you could exactly match the conversion behaviour of built-in types anyway, since in general there's no way to specify the rank of your conversion to match the rank of the conversion of the type you're imitating.

a == b will not compile, because function overload resolution ignores accessibility. Accessibility is only tested once the correct function is chosen. In this case the correct function is MyTestableClass::operator==(const MyTestableClass &), which is private.

I'm not sure if == and != are all the operators you need to overload, though, is there anything else you can do with a pointer to data member? This could get bloated. It's no better really than Bart's answer, I just mention it because your first attempt was close to working.

I'm facing an issue with the Jenkins Violations plug-in when trying to access my source code files from the UI. The paths are relative to the root of the volume :S. So, if my .cs file is in C:\CMSRootFolder\MySolution\MyProject\Namespace\SourceCode.cs, then the link in Jenkins is: http://<jenkins_server>/job/<job_name>/violations/file/CMSRootFolder/MySolution/Namespace/SourceCode.cs/

This happens even after setting the faux project path to "C:\CMSRootFolder\MySolution", and no matter what I try to set in the source code patterns. I think this might be a bug in the plug-in, but I would like to know if there is any workaround.

You need to assign your fields actual objects. If you look at Quiz.theContentManager, you'll notice that you never actually assign it a value. You can fix this by passing the ones in from Game1. For instance, Game1 should look like this:

Then your Quiz class should look like this (note that you don't need class fields for any of the XNA stuff with this approach):

Taghrid, It looks like you're getting a Stackoverflow error. This indicates that somewhere in your code you have Infinite recursion.

We've refreshed our EDMX data model and the new column appears just fine. We are on an ASP.NET 4.0 platform using C#.

We have a class defined as PagedList which inherits from List and implenents an interface IPagedList

I've tried searching for this type of exception but to no avail. The column appears in the EDMX dataset just fine. I even created a small throwaway program and imported the EDMX to do a simple read from the database and it worked fine. Has anyone run across something similar?

I'm learning Ada by fixing bugs and reading code. I've noticed some if statements that are ganged with "and" and others with "and then". similarly, there is "or" and other places there is "or else". A co-worker says it's just syntactic sugar and makes no difference. I wonder if he's right?

I'm building an android audio app that has to support the API level 10 and I have Larsen effect problems. My android app streams the audio to a java app that outputs the sound.

I found the AcousticEchoCanceller of android but it is only available from the API level 16.

Is there a way to do that without this class ? Or could I do it on the java app ?

There are a number of solutions. You should not assume that everyone has Java installed. You can use web start for instance which will help with the setup. You can find some advice here.

I'm new to Android and now doing a simple app that requires writing some data into a peripheral device.

Actually nothing goes wrong in a Samsung GT-S7272C device. But when I switch to Sony LT29i, there will always be a status 133 when I'm trying to write into a certain characteristic. I will give out some brief code.

Writing into first characteristic has nothing wrong and control will reach the onCharacteristicWrite and enter the first if statement with status 0, which means success. Problem is the second writing action in the if statement, which will also trigger onCharacteristicWrite function but yield a status 133, which cannot be found in the official site. Then the device disconnect automatically.

I've confirmed that the data type and the offset are all correct. And because in another device it works really nice, I think there might be some tiny differences of the bluetooth stack implementation between different device that I should do something more tricky to solve this problem.

I've search for result for a long time. Some results lead me to the C source code(Sorry, I will post the link below because I don't have enough reputation to post more than 2 links), but I can only find that 133 means GATT_ERROR there, which is not more helpful than just a 133. I've also found a issue in google group, discussing some familiar questions, but I failed to find a solution here.

I'm a little bit sad because, if it is something wrong with the C code, even if I can locate what's wrong, I still have no way to make it right in my own code, right?

I hope that someone has the familiar experience before and may give me some suggestions. Thanks a lot!

I am having trouble with multiple clicks being registered in jQuery when only one element has been clicked. I have read some other threads on Stack Overflow to try and work it out but I reckon it is the code I have written. The HTML code is not valid, but that is caused by some HTML 5 and the use of YouTube embed code. Nothing that affects the click.

In Firefox one click can log a "Click!" 16 times! Chrome only sees one, but both browsers have shown problems with the above code.

setupHorzNav is called by another function in my code. I have tested this and have confirmed it is only called once on initial load.

There are mutiple instances of nav 'prev-next'. All target different anchors. All are within the same html page.

Create a public bool variable and check against it for if the analytics have been sent previously.

You should be able to use the CASE construct, and it would look something like this:

Assuming you have interop, it would be like the below. Note xlValidateWholeNumber, that can be changed to xlValidateDecimal (and the subsequent Formula1 below would need to be a decimal) for decimals).

In adition to the break statement to exit a for or [do] while loop, the use of goto is permitted to break out nested loops, e.g.:

I am new in Java and now trying to develop a simple program to support my research findings. In this program, I'll be displaying randomized images and users were to enter single integer in jtextfield provided. The users are required to count and answer the number of animals displayed. Since I want to develop the program as simple as possible, I imagine my tool will be straight forward.

Question 1: There will be a JTextField provided for user to input their answer. Is there any coding that could restrict user input right after a single integer(between 1-6) has been keyed in the box? As I need my program to be straight forward and easy to understand, I do not want user to click on any button so as to lead them to next image. May I know is there any way to restrict user input and lead the program to next image right after user enter a number without clicking any button? Question 1

Question 2: Right after the user key in the single integer answer, I would like to prompt a simple popup that includes a praise to user such as "Well done". Since the JOptionPane I'll be using will contain two buttons: "OK" and "cancel", may I know how to make sure the program leads to next randomized image after user click on "OK" button. Question 2

Question 3: Is there any ways to keep the input cursor for typing just in the JTextField provided? This is because I want the program as simple as possible that user do not need to waste their time moving their mouse and click at the jtextfield to start entering their answer. I want my program to work like: everytime user enter a single integer, a pop up message appear, user click "OK" and lead to next randomized image. At the next image, user just have to enter the answer without moving the cursor to click at the jtextfield(Example:By referring to image question 2, after user click "OK", how to make the program leads to next randomized image as image question 1). May I know is there any way to develop the program in such way?

I'm attempting to use the distributed matrix data structure BlockMatrix (Spark 1.5.0, scala) and having some issues when attempting to add two block matrices together (error attached below).

I'm constructing the two matrices by creating a collection of MatrixEntry's, putting that into CoordinateMatrix (with specifying Nrows,Ncols), and then using the CoordinateMatrix routine toBlockMatrix(Rpb,Cpb). For both matrices the Rpb/Cpb's are the same.

Edit: Below is a small reproducer (not the original) for the problem. It fails for 1.3.0 and 1.5.0 at least. Is there a dense+sparse issue I'm not understanding?

You might look into using a modal for videos instead of the router if you want to overlay it on top of multiple states. If you stick with using the router, you might want to define videos as a child state of both home and portfolio instead of defining three states at the same level.

What this does is turn off the computer's ability to hibernate. It works fine when I double click the file. I can confirm this by going into the command prompt and typing "powercfg /a", which shows me that hibernate is indeed off. The problem is that this batch file doesn't seem to be running at logon even though it's in my Startup folder.

I've tested it by turning hibernate on using the command prompt ("powercfg -h on") and then actually putting my computer into hibernation. Then I turn it back on and log in to Windows. But when I open a command prompt and type "powercfg /a" it shows me that hibernate is still on. It seems the batch file doesn't run at logon even though it is in my Startup folder.

I've also tried making it run from a task scheduled to run at logon, but that didn't work either.

I'm trying to use for loop and read contents of a file line by line the file is an xml and contains urls and paths delimited by <>

i have already tried to pause or timeout the batch but nothing seems to work batch is anyway terminating

There is a very minor difference (effectively negligible, we're talking micro-optimization here), since the string should be stored in a local variable which takes that extra bit of memory on the stack frame of the corresponding method. Whereas the constants are actually stored in the constant pool and shared. With the likely optimizations of the JVM based on the number of invocations, it won't make a difference.

Note that the bytecode would be the same if the variables were final or effectively final (assigned only once), since in this case they are treated as constants.

Since the internal pointer of the stream is at index 4 after you write the data, you need to fseek back to the beginning of your stream:

i came across a MIT lecture on recursion where they checked palindrome using recursion,and there they checked it using logic where they compare first and last alphabet and so on.. what i thought is something as follows

Yes, absolutely, that's possible and pretty easy to do: all you need is to create an extension with a content script that will be injected into that particular page and remove the element for you.

In TreeView.SelectedItemChanged event, we get e.NewValue which is type of TreeViewItem, so I think you can use following code to select an item when it's group is selected.

The Disclaimer

First of all, I know this question (or close variations) have been asked a thousand times. I really spent a few hours looking in the obvious and the not-so-obvious places, but there may be something small I'm missing.

The Context

Let me define the problem more clearly: I'm writing a newsletter app in which I want the actual sending process to be async. As in, user clicks "send", request returns immediately and then they can check the progress in a specific page (via AJAX, for example). It's written in your traditional LAMP stack.

In the particular host I'm using, PHP's exec() and system() are disabled for security reasons, but Perl's system functions (exec, system and backticks) aren't. So my ~~workaround~~ solution was to create a "trigger" script in Perl that calls the actual sender via the PHP CLI, and redirects to the progress page.

Where I'm Stuck

Problem being, it's not returning immediately, but waiting for the script to finish. I want it to run in the background and have the system call itself return right away. I also tried running a similar script in my Linux terminal, and in fact the prompt doesn't show until after the script has finished, even though my test output doesn't run, indicating it's really running in the background.

What I already tried

My test environment

Just to be sure that I'm not missing anything obvious, I created a sleeper.php script which just sleeps five seconds before exiting. And a test.cgi script that is like this, verbatim:

What should I try now?

Can anyone help me with this. I am trying this following code for the fragment which I am calling from a navigation drawer:

I want to add SDL and SDL_image to my Visual Studio project. But can I do it locally only for this project? I don't want to put the dlls in System32 folder.

In my company's toolkit, we implemented a technology we call remote invoke. This consists of two parts - on the client side, there is a javascript method called RemoteInvoke() which takes a method name and an array of arguments to pass to the method. On the server side, you decorate a public method you would like to call with the attribute [RemoteInvokable]. RemoteInvoke matches signature as best as it can (type casting if needed) and then called the appropriate public method (if it found one).

It's not for things as simple as click actions, but it if you need more complicated things, it will work just great.

I'm using FluentData as an orm for my database and I'm trying to create a generic query method:

An anonymous function or method group connot be used as a constituent value of a dynamically bound object.

I am using a JQuery plugin datepicker that allows me to set options e.g. default date, format, minimum date etc.

I am loading content via Ajax into a modal, but am then trying to bind those elements that have been inserted into the DOM with a call to the datepicker plugin.

The following code has worked fine on other code but i cant find a way to use it with plugins, is this even possible without modifying the plugin?

It's best if you can add a field that will not display on the application for the file unique_id in the table and then use that in a join to the data to populate the child tables. But sometimes you can't mess with the structure of a database especially if it is a COTS product.

We have a sneaky trick for that. First load the data to a staging table (adding an identity if the file has no unique identifier on it's own) and an empty field for the parent_id.

Next put the unique identifier into some other required field instead of its normal value (We use last_name but if you have one taht is the same datatype as the uniqueid that's better). Then you can join on the required field and the uniqueid from the staging table to update it to get the real parentid. Then update the field where you stored the temporary id with its real value (becasue now you can use teh real parent_id). Now you have the real parent_id in a table, the data flows for the child tables can join to that. This creates more work for the database, so only use it if you can't change the structure.

Alternatively you can do all the inserting from a staging table using a stored proc and the execute SQL task rather than in a dataflow.

I'm new to Perl and I understand you can call functions by name, like this: &$functionName();. However, I'd like to use an array by name. Is this possible?

In addition to what others have said, pointers are necessary for dynamic memory allocation (this also applys to higher level languages, but is (usually) abstracted away). This means that without pointers, you're limited to the (generally rather small) stack memory, which is more in need of conservation.

I have tried severally without luck importing jquery to global scope using webpack with below methods , but all throw errors :

Suppose your dataObj contains a unique ID field, then any set data structure would be fine for your job. The immutable data structures are primarily used for functional style code or persistency. If you don't need these two, you can use HashSet<T> or SortedSet<T> in the .Net collection library.

Some stream specific optimization may be useful, e.g., keeping a fixed-size Queue<T>for the most recent data objects in the stream and store older objects in the more heavy weight set. I would suggest a benchmarking before switching to such hybrid data structure solutions.

After reading your requirements more carefully, I found that what you want is a queue with user-accessible indexing or backward enumerator. Under this data structure, your feature extraction operations (e.g. average/sum, etc) cost O(n). If you want to do some of the operations in O(log n), you can use more advanced data structures, e.g. interval trees or skip lists. However, you will have to implement these data structures yourself as you need to store meta information in the tree nodes which are behind collection API.

When I run liquibase update from scratch, it takes a while as the process fires each changelog one by one. Sometimes my own database changes diverge enough that its easiest to rebuild the database if I want to start again for example.

The rebuild would be quickest if I did it from a mysql dump of the result of liquibase at a certain point in the changelogs, and I ignored the changelogs from there previously. So I would delete everything in changelog master except my master build dump changelog, which would be the entire database, and I keep hold of the actual changelogs for version control reasons.

In iOS 6 everything works fine. The keyboard opens and moves the input into view. When the keyboard closes everything goes back where it should.

In iOS 7 the keyboard opens fine and the input remains in view. When the keyboard is closed the whole bottom half of the app is gone, though. I've tracked the issue down to the height of the window changing when the keyboard is opened, and not changing back when it's closed.

Right before the keyboard is opened the window height is 568 according to $(window).height() and after it's opened and after it's closed it is 828. The height of the document also changes accordingly.

I've also attempted to set the size back after the keyboard closes with no success.

I have declared an extern global variable inside my main.h header file like this:

The thing is that I am using another file called test.c, and I have included main.h header included inside. But I cannot gain access the the "16" value that I defined the extern with inside main.c. When I call "variable" inside test.c, the value of "variable" is "0". Should not any .c file that includes my main.h header have access to the "16" value since I have already defined my "variable" inside main.c???

Hi guys I have a multicast socket that is receiving packets and is working fine.

I had an issue though where when my computer wakes up from sleep the multicast socket does not work. Continually timing out:

Currently when my computer wakes up from windows sleep mode it continually throws a socket exception when I no their are packets being sent. I have checked variables socket.isBound(), socket.isClosed(), socket.isConnected() and they have not changed from when it was working. Am I missing a variable? Even when the socket is working it returns isConnected() = false, isBound() = true, isClosed() = false.

Do I need to do something like count the number of SocketTimeoutExceptions if i get 10 then reinitialise my multicast socket?

I have tried adding a center page and side bars to my site but the only problem is the div tags merge and the backround color of the nav bar takes over the side bars even if the style code is separated heres an example

So All of my decimals are rounded to two places. However when I click on "keyboard or mouse" image the decimal place is roughly ten digits long( for example:36.900000000000006). How do I stop this. I've tried using ".toFixed(), and .toPrecision().

And I want the text to be aligned at the bottom of the 32dp and center horizontally..currently it's not centering horizontally:

I have a page, that lists a collection, that can be filtered. As there are some fancy effects (hover dimming) on these items, they have to be applied once the page has loaded.

This works fine, but when I select a criteria that hides an item, and then make it reappear by deleting that filter, these effects are no longer applied to these items.

I have tried to create a template.rendered function, but that only works on the first page load.

I also thought that adding a 'hover #mydiv: function () {...}' inside the template.events section could help, but that still doesn't work.

I have even tried to listen to the changes made in the drop-down ('change #myselect': function () {...}) where the filters can be applied, but that's not working either.

I also tried to tie it to a dependency, that is submitted when the criteria is selected, that has also failed.

The issue was resolved when the project was migrated onto another machine. Apparently the error had nothing to with incorrectness related to RMI. Although, the cause of the error and why it didn't resolve even after re-building the project is still unknown.

After I clear the ArrayList, call getAbsentTeachers() and notifyDataSetChanged() the ArrayList appears to remain empty even though getAbsentTeachers() is beeing called. I know this because nothing is displayed in my ListView.

getAbsentTeachers() populates the ArrayList fine when my app is first launched however it doesn't seem to work when I call it again to update the ArrayList.

regarding pointer type: the idea here is that in order to reduce both loop and copy overhead, you want to copy using the largest data "chunks" (say 32bit) possible. So you try to copy as much as possible using 32bit words. The remainder then needs to be copied in smaller 8bit "chunks". For example, if you want to copy 13 bytes, you would do 3 iterations copying 32bit word + 1 iteration copying a single byte. This is preferable to doing 13 iterations of single byte copy. You could convert to uint32_t*, but then you'll have to convert back to uint8_t* to do the remainder.

Regarding the second issue - this implementation will not work properly in case the destination address overlapps the source buffer. Assuming you want to support this kind of memcpy as well - it is a bug. This is a popular interview question pitfall ;).

Also can try as suggested by Scott, but the if else would be the other way round:

I want to make the text size in the pickerView to become smaller if the text does not fit in the label. For example, whenever the text shows like this "This is a test for somebo..." I want it to automatically size itself to a smaller size so it should fit. Here is the code I'm using:

I tried to set the number of lines to 0 but that didn't solve my issue. I then tried to make the label sizeToFit, and that didn't work either.

I also tried making the label's frame height, taller, so it would be multiple lines, with didn't help either.

i deployed an application on SAPUI5 Repository, when i added it to Fiori launchpad the app could not start and it's giving me the following error while debugging :

I'm new to ExpressJS and NodeJS in general, so I need directions on how to achieve this effect:

So that when I request sub1.domain.com the first handler reacts and on sub2.domain.com I get response from second handler. I've read some questions on SO about using vhost for this purpose, but I'd be more happy if what I described above worked rather than creating multiple server instances like in vhost.

As documented, the item's transformations are mathematically applied in a certain order - this is the order you'd be multiplying the transform matrices in and is, conceptually, the reverse of the order you'd normally think of.

When you set transform to scaling, and set rotation, the rotation is performed before scaling. The scaling applies to the rotated result - it simply stretches the rotated version horizontally in your case.

You need to somehow enforce the reverse order of operations. The only two ways to do that are:

I'll demonstrate how to do it either way, in an interactive fashion where you can adjust the transform parameters using sliders.

I think teamnorge is on the right track His code won't work as posted, though, since the array isn't mutable.

Make your property a mutable array. Have the base class create it it init's init method:

For efficiency's sake, it might be better to make the array immutable and have the subclass's init method replace it with a an array created using arrayByAddingObject or arrayByAddingObjectsFromArray. (Immutable objects are less costly for the system than their mutable forms. In this case the array of properties will only be created once at initialization of your class, and then persist for it's lifetime.)

setInterval(function(){ object.style.backgroundColor=bgcolorlist[Math.floor(Math.random()*bgcolorlist.length)]; },5000);

BTW, I assume you meant O(n) because O(1) (as other people have mentioned) is obviously impossible.

as you are neither running your app in daemon mode or in the main interpreter because of the directives being in the wrong context.

That Directory directive then conflicts with one for same directory above so merge them.

If using mod_wsgi 3.0 or later count instead perhaps drop that second Directory block and use:

Note that processes=1 has been dropped as that is the default and setting it implies other things you likely don't want. You also don't need to set user/group as it will automatically run as the Apache user anyway.

The type inference is just a shortcut for an unnecessarily long way of instantiating paremeterized types. Generics are still implemented by type-erasure, so your bytecode will only have the raw types.

First of all don't add the validator (or anything else for that matter) into vendor namespaces. Instead put it somewhere within your application code. Don't know how your app is structured, but lets say ./module/YourModule/src/YourModule/Validator/ZendValidatePesel.

Then reference your validator class with a full, qualified name, so following my guess it'd be something like:

As far as I know that will directly instantiate the validator for you. Not-so-fun-fact: even if you'd register your validator there under the same name as the fqcn, it won't go through the ValidatorPluginManager -- something that I hope will be, or already is fixed in the framework (if it is somebody let me know, because it'd love to have validators with dependencies at last).

Issue was with JTDS driver as soon as I switched to JConnect driver everything began to work as expected.

But since I guess that what you have is an object url (blob://), then your solution is either to get the real Blob object and pass it to a FileReader, or to draw this image on a canvas, and then call its toDataURL method to get a base64 encoded version.

But note that for the later, you'll have to wait that your image actually has loaded before being able to draw it on the canvas.
Also, by default, it will convert your image to a png version. You can also pass image/jpegas the first parameter of toDataURL('image/jpeg') if the original image is in JPEG format.
If the image is an svg, then there would be an other solution using the <object> element, but except if you really need it, I'll leave it for an other answer.

I have a storm topology that subscribes events from Kafaka queue. The topology works fine while the number of workers config.setNumWorkers is set to 1. When I update the number of workers to more than one or 2, the KafkaSpout fails to acknowledge the messages while looking at storm UI. What might be the possible cause, I am not able to figure out, the exactness of problem.

The entire difference is like you said, in texture caching. So choosing between either of these methods depends on whether or not you will want to exploit texture caching in your visualization. Lets look at some common cases:

a) If you want to calculate how a surface is deformed (for example the surface of water, or maybe some elastic deformation) and you need to know the new vertices for the surface's polygonal mesh then you would typically use Buffers (Number one), except you wouldn't need to copy to an OpenGL texture here. In fact there would be no copying involved here, you would just reference the buffer in CUDA and use it as a gl buffer.

b) If you have a particle simulation and need to know the updated particle's position, you would also just use a buffer as in the above case.

c) If you have a finite element grid simulation, where each fixed volume cell in space would gain a new value and you need to visualize it via volume rendering or isosurface, here you would want to use a texture object (2D or 3D depending on the dimensionality of your simulation), because when you're casting rays, or even generating streamlines you will almost always be needing to immediately have the neighboring texels cached. And you can avoid doing any copying here, as in the above method you could also directly reference some CUDA texture memory (cudaArray) from OpenGL. You would use these calls to do that:

and so this texture data in CUDA can be referenced by mycudaArray while this same memory in OpenGL can referenced by textureNameFromGL.

Copying from a buffer into a texture is a bad idea because if you need this data for texture caching you will be doing the additional copy. This was more popular in the earlier versions of CUDA before texture interop was supported

You could also use textures in the a) and b) use cases as well. With some hardware it might even work faster, but this is very hardware dependent. Keep in mind also that texture reading also applies minification and magnification filters which is extra work if all you're looking for is an exact value stored in a buffer.

I have a URL that I need to manipulate. I cant seem to replace all the '+' within a query string with whitespace.

I am writing unit tests for my angular 2 component with Jasmine framework and somehow Jasmine always skips my spec if I include directives not from the angular original module (in my case the test only works with directives for example from angular/core and angular/common). This is my app component:

The spec is run if I only include NgStyle and NgFor in my list directives. When I tried including anything from different libraries, such as CollapseDirective or MdDataTable, the spec is skipped -- jasmine test does not show success or failure. Any suggestion is much appreciated! Thanks

I've succeeded in moving all other controls on a Google map with the following small screen css:

This is needed to move the map controls below a logo on a mobile/small screen version of a site. The pan, zoom and map type controls all move correctly but the Peg Man stays in its original position which is behind the site logo (which I can't move easily).

The element identifier used in the above css is what the Firefox inspector claims is the Peg Man image but I've also tried removing weekend from the end of that identifier to modify the div tags rather than the image - the Peg Man just won't move!

As you can see it is still not perfectly segmented. Any suggestions on how to further "clean" this segmented image? Here is my code:

However by doing this your user will have to restart the application unless you call this in the main() method before UIApplicationMain() is called

I am using CurrencyLayer to convert the following format in Talend. This is what the format looks like:

Within Talend, I have created the FileInput using this URl and I can parse the timestamp, source. But how would I get the USD, CAD, and their respective rates and how would that be mapped to input into the database itself.

While allowed_children_ids is a set of records, allowed_children_ids.ids is a list of ids of those records.

You can also approach this from the other side. This should work and be event faster:

My emulator was android 4.0. So i modified my emulator and made api level 4.0.3(apilevel 15). It worked.

Basically, your regular expression is recursive. Removing the final .+ solves the issue. Here is a good article on avoiding it in the future. Why does .NET hang? Probably because it will never abort the search. Perhaps the JavaScript parser you used aborts if it detects too many steps or goes too deep into recursive searches.

you could try wrapping your message in a <pre>...</pre> tag, so linebreaks get rendered by the browser :-)

If this will not help you than go to. app\build\outputs\apk and delete your apk. and again build signed APK.

Recently I've started working on Django, got myself a situation which I can't find the right solution on the web to solve it. So I've got a little question about URL reversing on a success. Currently when an user successfully creates an account, the user gets reversed to a profile based on the user_id which just got created:

This is working properly. Now I created a profile module with a OneToOneField to the django.auth.models User model. When creating a new account, a signal is send to the create_profile_on_registration method.

This is also working properly, a new profile is created on user account registration. Now I would like to reverse the user to the new created profile_id instead of the user_id. However, I cant figure out exactly how to get this properly to work. Can you give me a little push in the right direction on how to approach this issue? I can't match up the right google search words or find any examples which explains or shows how to achieve this properly.

If I load in a cookie, I am able to get to the page that requires cookies, like this:

I have set up a dump script on my local server, to see if it is working. If i send only the cookie, I can see it in the http headers, and if I send only the post data, I can see the post data.

I need to group some elements together and pull them together under a new element.

Below is a sample record, I would like to group together the address information into an additional layer.

I don't understand what exactly you are trying to do. If you want to get an array of pointers from your array of structs, you will need to make a loop. It would look like this (i did not try it)

I am writing a simple program in asp.net mvc5 that will display a calendar. I have an array that stores the months and days 1-31. I would like to use an if statement to check for the month to allow only the appropriate number of days. I am really new to mvc and would appreciate any suggestions on how to accomplish this.

Yes, that is a much more complicated task. You're going to have to store the last modified time into a database (since you're saying users can modify their profile content I'll assume you already have a database). The easiest way to get the last time the user modified their profile depends on your schema.

To put it another way... what the user is actually modifying isn't "profile.php", it's some data that lives elsewhere, e.g. a MySQL database; so the system that's going to know when the user last modified it is that external data source.

Why wouldn't be corrupted? You are opening a document, getting all of the child elements, and writing them to the same document. I am not sure what is that supposed to do.

Overdispersion isn't really a useful concept in the normal model because it is already fitting a variance for the variability at the observation level. So the error message is telling you that you can't have a grouping factor at the observation level. In that sense, yes, you are trying to overfit your model.

In a poisson (or other glm) model, however, it does make sense, because the variability at the observation level is fixed according to whatever the variance term in the glm is, so it does make sense to add an additional variance term to the model to account for any extra variability at the observation level. Hence glmer does not do the same check that lmer does.

This question has been answered already, but I want to point out that form_open() without any arguments would do exactly what you want (creating an action="").

At this time

text-stroke is actually avalaible in webkit , using vendor prefix. So is text-fill.

how to use it in webkit browser :

for now

To stroke text in CSS, you need to use multiple text-shadow to increase as much as needed the shadow to turn it into a full strike color .

(as bigger is the shadow used for stroke effect, as much it needs to be repeated, redrawn)

If you look at the source code in http://webtimingdemo.appspot.com/ it runs the code AFTER onload (setTimeout('writeTimings()', 0)), your code runs in $(document).ready() which runs before onload as it runs on DOMContentLoaded in Chrome.

on the first how did you run your App? I noticed that when i run an App in Debugmode, the Debugger eats 50% of the performance of my mobile Device. So if you just run your App the onFinish works much faster.

A second point is to detect the timeout manually in the onTick Method an block the taps after some time with a boolean

This is a bit around but its maybe faster and you have to add the "tapBlock" to the update method

With all the hints I found out that DataGridTextColumn is neither part of the visual tree nor of the logical tree. That should be the reason why ElementName and RelativeSource do not work. This answer regarding DataGridTextColumn explains that and gives a possible solution with Source and x:Reference: DataGridTextColumn Visibility Binding

The answer of @Anand Murali works but cannot be applied to Visibility - that was not part of the question because I minimalized that away. So I accept that one and will give more information in this one.

But: I my example I use a ControlTemplate and to have x:Reference to work this template must be within a .Resources XAML part in the same file and cannot be in an external ResourceDictionary. In the latter case the reference will not work because it cannot be resolved. (If someone knows a solution to that it would be welcome)

It can happen, that the string has nothing inside, than it is "None" type, so what I can suppose is to check first if your string is not "None"

I've been searching all over and found a bunch of examples of ways to send a picture to a web server. So far none have quite worked for me. Maybe I started in the wrong end but I've already written the code for the controller which is to take care of the received picture.

I'm using a Tomcat web server and written all the code on the server side with Spring Tool Suite with the MVC Framework. The controller is written like this:

So basically what I'd like to know:
How can I write a class/method that sends a picture from my phone to the web server?

I suppose total revenue is only shown for the period of time selected, if you view a 30 or 90 days window, total revenue going down means the revenue over that period is lower than it was for the previous same-length period.

Selects the entire sheet but it's not changing the vertical alignment to center.

I found out the column has VerticalAlignment set to xlCenter but the Cells underneath the column do not have VerticalAlignment set to xlCenter.

the solution was in the -validateMenuItem code... I wasnt checking for a return value of null somewhere that method and it was logically returning false.

whereas your second loop is a bit buggy and the cause of the fault. If I expand the loop, what happens is:

i.e. what you think is fetching data2 and data3, you are really only using the strings 'data2' and 'data3' (note the quotation marks).

Without assuming too much of your data and restructuring you entire code, this should do the trick (for the second loop). Since you only have three data-files, looping seems a bit extensive contra the problems they are introducing.

To further comment your code, in your read.table call, you have two nested paste calls, which in this case is unnecessary.

paste(paste("data", i, sep=""),"_lambda.dat",sep="") # could be done with paste(paste("data", i, "_lambda.dat",sep="")

I have found in the past that there are 3 dlls you need to have the correct version of for debugging .Net.

here's how I usually go about getting these dll's http://sjbdeveloper.blogspot.com.au/, although it sounds as though you are using a server based application which means you could possibly just grab them from your production box, assuming you have access to it, or a staging box if you don't.

I suppose you need an ANE - unless Adobe extends flash.notifications one day to support Android too.

PROBLEM:

I'm betting that you have a one-dimensional array with strings stored in each. So your array actually looks like:

SOLUTION:

When constructing your 2D array, make sure you explicitly declare each entry in board as an array. So to construct it, your code might look something like this:

The answer is in apple SCNNode documentation. Try using flattenedClone() method instead of clone(). And one more thing, it's not needed any for statement. Here is a little example in Swift:

Here's a screenshot of my application. When the search box is clicked, the soft-keyboard automatically pops up, which is fine, but, if I also press the "Menu" button, the menu appears on top of the soft-keyboard.

How can I show the menu but collapse the SearchView if it is in focus and also hide the soft-keyboard. I probably need to check and do something in the onPrepareOptionsMenu method of my Activity, right?

It doesn't cause any real harm to me but it seems like an ugly implementation to the user when this happens.

The behaviour of this operator is different across various versions of Ruby. You're probably using an older one, in which case this is to be expected.

This has been changed and the newer versions of Ruby (1.9.x and above, according to this site ) simply print the character as a String. See the docs for Ruby 2.1.0.

Ruby 1.9.3, which I happen to have installed on the machine I'm using displays exactly the same behavior:

I am using pyperclip.py to grab a list of E-Mail Addresses in my web app using a form so a user can paste it locally via clipboard. It works perfect locally. However, while running it on a server (Linux 14.04 with Apache2) and accessed from a client system through the browser it doesn't copy. How can I get it to copy to the clipboard of the client's system?

Right now I'm just trying to get it to work and as such I'm only using a single line. I'm using pyperclip 1.5.15 with xclip and Python 3.4. The server is running Linux 14.04 and the client has noticed issues on Windows 8 and Windows 10 using Google Chrome and IE. No other os has currently been tested.

The following code should help. You should split each subject into a separate array within your query. Once your query is complete, you should iterate through the subject array, and then within each staff id.

Try this : WHERE IV00101.ITEMNMBR = IV00102.ITEMNMBR AND IV00102.ITEMNMBR = ItmPrice.ITEMNMBR group by IV00101.ITEMNMBR ORDER BY IV00101.ITEMNMBR

How about writing 2 servlets, one to take in the image and write it to the database and another one to get the image and pass it back in the response output stream which you can call from the webpage via an ajax call.

just get rid of chars that your are not interested after your keyword or match the end of string

already you can write like this: SampledbDataContext sdc = new SampledbDataContext(Server.MapPath("~/Sampledb.mdf")); or in design.cs file public SampledbDataContext() : base(global::"[write cnn string Here !]", mappingSource) { OnCreated(); }

When you open a MongoDB connection with the native driver, you're actually opening a pool of 5 connections (by default). So it's best to open that pool when your app starts and just leave it open rather than open and close the pool on each request.

You're on the right track with closing out your HTTP response; just call res.end(); when the response is complete (i.e. when item is null in the cursor.each callback).

It will mean the DB will need to stop less often to grow, certainly, and data inserts will occur more frequently. It will reduce the impact of data file growth. However, Microsoft says that autogrow is not intended to manage planned file growth. It's intended to handle unexpected growth. Autogrow is just not designed to work the way you're using it. The design intent is that you know how much data you will be storing and you have planned accordingly and already correctly sized your DB.

This might be somewhat unrealistic given your application, however. If your system is designed to hold all data ever collected indefinitely, your capacity planning is a bit difficult.

This is why it's common practice to differentiate operational data from warehoused data. Your operational data is stored in one database, which you can predict the growth for within a given time frame (usually 1 or more years). After a period of time, older data is archived to data warehouses, which may be very large or single year containers, but since data is inserted here rarely, you know what your capacity is going to be.

If I were you, I would pick a time frame to plan for. Say one month, quarter, or year. Every period of time, manually grow your database large enough so that the free space is what you expect to need to accommodate the coming period. Don't forget to include index space! Use the SSMS reports to help your estimates!

This means you can do your growth during off-hours or maintenance windows and your application is never waiting on the DB to finish growing. I would then set autogrowth to be about 5% of the free space you're planning for. If you underestimate, you'll get an idea by how much when you look at your shrink/grow logs. You can then increase for next month. Eventually, you'll learn what you need on a monthly basis. Just make sure to grow based on free space in the database and not absolute file size.

Because of security issue, we need to use minimal number of ports (blocking unused ports as many as we can).

I have tried to use the same curl handler object (CURL object) and set CURLOPT_LOCALPORT to a port number. The first request is ok. But in the second, libcurl verbose mode said address already in use. However, when I comment out the port set through CURLOPT_LOCALPORT, it works on second connection also, and by setting VERBOSE to 1, I can see "Re-using existing connection" print out, which is missing in version setting up local port. And I check with linux netstat, find out that it is using the same port. I cannot figure out why setting up local port will make it failed.

And also, I have tried to close the connection using curl_easy_cleanup, but due to tcp time_wait state, we cannot reuse the port in a while, that's not what I want.

Edit My reason using one port is not to keep opening and closing connection too much.

If all goes well with the steps above, Git is certainly connecting to the GitHub hosted repository. Try the git push origin fefixex again.

Your best bet is probably to use shell_exec to cat some of the data from the various /proc/* files that are commonly used on Linux/Unix systems, the key ones probably being:

First, make sure you check whatever code you are using on your Analytics. The first answer provided here pasted a code using Google GA.JS code, but many websites today uses the new Analytics.JS code (my case). So my suggestion is to copy your GA code from your website or from your GA panel.

Second, check if your GA code is being passed on your Instant Article RSS feed correctly (i'm assuming you are using Wordpress with some plugin to build a RSS). If you are using the new analytics.js method the code inside your RSS feed (per article) should be like this:

Third, if your articles were already on Facebook Instant Article Production list BEFORE you added the Analytics code, they will NOT update / load the code. The best way to test is to edit any of your articles (a simples change of punctuation is enough) and republish it on your wordpress. Then go to your IA panel on Facebook, Configuration and click to reload / rebuild your RSS. Wait a little then check on the list of I.A that the post will update (you will see the date change), then open it on the edit option and check at the end of the code. Your GA code should be there.

So, if everything is good now, your last step (at least was for me) is to delete all the old Instant Articles on Facebook (I'm assuming you don't have them published yet) and reload the RSS feed on the Configuration area, so it will rebuild your articles with the GA code on them.

A rewrite rule like this will prevent files existing on disk not to be rewritten:

As for your second question, please clarify, im not sure i understand what you mean.

No , dont do that . loading remote website will not able to intract with your plugins . and the app will get rejected on istore too

You can't directly call click on something in the control. However, you can register some JavaScript into the control and perform the click that way.

You can use the Windows.Web.Http.HttpClient instead of System.Net.Http.HttpClient, i.e.:

I have problem with binding to dependency property of my new control.
I decided to write some tests to examine this issue.

The result is good - when I writing something in first TextBox -> second TextBox is updating (conversely too).

I created new control -> for example "SuperTextBox" with dependency property "SuperValue".

Test is correct too! When I writing something in TextBox, SuperTextBox is updating. When i writing in SuperTextBox, TextBox is updating. All is ok!

In this case, when I writing something in SuperTextBox, TextBox is not updating! enter image description here

PS: Question is very very long, I am sorry for that, but i tried exactly describe my problem.

I am using Rails 4.1.1 Why do I have to click twice for jQuery effect to show? I have been Googling but I cannot find any solutions, not sure if there's something wrong with my jQuery code or....

You can in upload script use a temportantly file (in temportantly directory) and if upload was finished you can simple move file to your final location with good filename.

But if your using this function you must copy file before you close handle to it because this file was removed when you call fclose(handle). To get assurance of file buffer is clean you can at end call fflush(handle).

Prefix is a prefix to your files to easly group her to delete or something. Call this function to get unique file in typed directory, as directory get you temp directory in your enviroment, you can get this by calling:

Then when you have self tempfile, write to it upload data and close. Copy this file to your final location using:

Make sure your Class name field is actually Module.Task, where Module is the name of your app. CoreData classes in Swift are namespaced. Right now, your object is being pulled out of the context as an NSManagedObject, not as a Task, so the as-cast is failing.

It has no effect on other functions. It only has effect if your program uses COM interop.

When you use the hashtag (#) within a .find key, KineticJS searches for a node id.

So when you create each path (room) you should assign it a node id (eg "Room1"):

I have found the solution. The problem is with setting the contentScaleFactor of UIView. By default, it is 2.0 for retina displays. So, it should be set to 1.0. Here is the link for more details: UIView ContentScaleFactor

As far as the rest of your program is aware your wait_queue is just a Collection, it doesn't have get or remove methods.

You're correct in that you don't want to couple your implementation to the variable's type, however you shouldn't use Collection unless you only want to iterate over the contents. Use List, Set, or other collections interfaces to describe collections. These expose the get and remove (in the case of the List) methods you want, and expose the behaviour of the object (but not the implementation - in this case ArrayList). e.g., a List allows duplicates whereas a Set does not.

I need to return all authors where Jeff D Ullman is a coauthor but in the list I cant return his name. So i get all books he is an author in and print them out. If his name is there dont print it out. My if then else statement is not working. Any ideas????

You should login your user again and only after that attach the file.I had similar situation when i took a picture using camera. I did this. Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivity(intent); CameraActivity was started and connection was lost, so you need to reconnect if you want to upload the file.

There is a config.inc.php under setup/frames, this is the one you are showing us but it's not the one that contains the configuration. Look at the main directory containing all the db_* and tbl_* scripts. However, phpMyAdmin is able to run without a config.inc.php.

there are so many posts here, were people ask how to draw lines with a brush in CGContext. The answer always is: Use a pattern. However, I tried this for some hours now and the main problem to me seems to be: It seems like CoreGraphics simply draws the pattern as a fill and then simply clips this pattern with the stroke of the path you specified. This leads to some bad looking tile-borders and it simply doesn't look as someone really draws something by hand. What I want is something were the brush is painted along the path, without any clipping. I basically want to move along the path and simply draw the brush image every x points, in distance, on the path, with the size of the brush. Is this somehow possible with CoreGraphics or is this just something you have to implement on your own?

//EDIT: Sorry, I thought it was clear what I tried by saying, I used a pattern. This is what I did so far:

The <html> background is "behind" the <body> background. Try this to see what I mean:

In detail: The systems interrupt time slices are given by ActualResolution which is returned by NtQueryTimerResolution(). NtQueryTimerResolution is exported by the native Windows NT library NTDLL.DLL. The System time increments are given by TimeIncrement which is returned by GetSystemTimeAdjustment().

These two values are determining the behavior of the system timers. They are integer values and the express 100 ns units. However, this is already insufficient for certain hardware today. On some systems ActualResolution is returned 9766 which would correspond to 0.9766 ms. But in fact these systems are operating at 1024 interrupts per second (tuned by proper setting of the multimedia interface). 1024 interrupts a second will cause the interrupt period to be 0.9765625 ms. This is of too high detail, it reaches into the 100 ps regime and can therefore not be hold in the standard ActualResolution format.

Therefore it has been decided to put such time-parameters into double. But: This does not mean that all of the posible values are supported/used. The granularity given by TimeIncrement will persist, no matter what.

When dealing with timers it is always advisable to look at the granularity of the parameters involved.

So the idea of introducing a double here is not such a stupid idea and actually makes sense. Spending another 4 bytes to get things finally right is a good investment.

A retain cycle would be self.A = self; or more likely, self.A.someStrongProperty = self.

Edit: In the case you have edited above, assuming self is a view controller, it would not deallocate because of the retain cycle. You should change your someStrongProperty to be a weak property, which will prevent the retain cycle.

well, I've been thinking of making database requests a little faster by keeping the connection to the database open as long as the object is being used. So I was thinking of opening the connection in the constructor of that class. Now the question is, how can I close the connection after I stopped using? I have to call close() somewhere, don't I? I've been reading about the finalize() method, but people seemed to be skeptical about usage of this method anywhere at all. I'd expect it to have something like a destructor, but Java doesn't have that, so?

Just plot each segment separately. This also allows for more flexibility as you can independently change the colors, add direction arrows, etc, for each connection.

There are duplicate lines here based on how you presented the connectivity, for example, (0,1) and (1,0). I'm assuming that you'll eventually want to put in the direction, so I left them in.

If you are using .Net 4.5 you can save yourself some key strokes and use the TPL

I am trying to get a users group membership and limiting the results to those that match a string, ie I am only interested in the users group membership where the group begins with "test-".

The following is what I have been playing around with, even though the user is apart of several groups that match the search string, the If statement is not returning True on any of them.

Is there any way of applying a search or If statement agains an Object where the constraint is a wildcard?

The groups I am looking for could be one of about 60 (this amount does increase and decrease as staff leave).

I'm not getting any results and an exception is thrown when trying to perform "ToList()" on "serviceTraces" object.

According to Quick start guide of laravel if i visit http://localhost/laravel/varadha/, i should get a welcome message. but i am getting this message.

Finally, I find there's a lock when compiling prepared statements. I was compiling a new prepared statement whenever a new request come in, after I changed to reuse it I got my app server scale. However, I still don't know why cross-region case can scale.

I had this problem and it took me forever to figure out. The Child table has to allow nulls on it's parent foreign key. NHibernate likes to save the children with NULL in the foreign key column and then go back and update with the correct ParentId.

I'd like a dict-like class that transparently uses transformed keys on lookup, so that I can write

etc. (Imagine for example that f does some kind of canonicalization, e.g. f(k) returns k.lower().)

It seems that I can inherit from dict and override individual operations, but not that there is a centralized spot for such transformation that all keys go through. That means I have to override all of __contains__, __getitem__, get, and possibly __missing__, etc. This gets too tedious and error-prone, and not very attractive unless this overhead outweighs that of manually substituting f(k) for every call on a plain dict.

I'm trying to install this package from source on Windows and cannot work out what is going on and what I need to do in order to get this working.

I have the tar-gz file from CRAN, I have R-3.1.2 installed and RTools installed.

In the source for the libxml2 I can see the parser.h file mentioned in the error but what do I do with it or the library in order to get this install working?

Yes, as long as your controller inherits from Controller (which it must in order to work as an MVC controller), you can use the same syntax without the <%= %>.

alternatively if you reference the MVCContrib DLL, you will have access to strongly typed helpers, and be able to do something like:

new_array = X.map {|object| object.class == BigDecimal ? object.to_s : object } then turn it into a string with new_array.join("")

What you want to do is sort an array, whose elements are hash, based on the hash's "code" value.

For specific reasons, I'm implementing my own font rendering, and an algorithm to compute the bounding box of a text by using bounding boxes of single glyphs, together with the respective advance, is needed. For clarification see this illustration:

For every of these N glyphs is given the relative bbox relative to the origin (xmin, xmax, ymin, ymax), and the advance (pseudocode):

Use mouseenter and mouseleave. The problem is that mouseoever/mouseout get triggered when you move between child elements, which you don't want.

Theres no formal difference between 'Text classification' and 'Sentence classification'. After all, a sentence is a type of text. But generally, when people talk about text classification, IMHO they mean larger units of text such as an essay, review or speech. Classifying a politician's speech into democrat or republican is a lot easier than classifying a tweet. When you have a lot of text per instance, you don't need to squeeze each training instance for all the information it can give you and get pretty good performance out a bag-of-words naive-bayes model.

Basically you might not get the required performance numbers if you throw off-the-shelf weka classifiers at a corpora of sentences. You might have to augment the data in the sentence with POS tags, parse trees, word ordering, ngrams, etc. Also get any related metadata such as creation time, creation location, attributes of sentence author, etc. Obviously all of this depends on what exactly are you trying to classify.. the features that will work out for you need to be intuitively meaningful to the problem at hand.

Like the other answers above, i agree that this is just asking for an injection attack (and probably other types). Some things that you can do to prevent that and enhance security in other ways could be the following:

1 Look for something suspicious with your response handler. Lack of a query variable in the post, for instance, doesn't make sense, so it should just kill the process.

3 Use more fields, even if they are semi-meaningless and hidden, to add more reasons to kill the process through their absence, or lack of a certain text pattern (optional).

4 You shouldn't send a complete query through the POST at all. Just the elements that are necessary as input from the user. This will let you build the query in PHP and have more control of what actually makes it to the final query. Also the user doesn't need to know your table names

5 Use mysql_real_escape_string on the posted data to turn command characters into literal characters before entering data into a db. This way someone would have a last name of DROP TABLE whatever, instead of actually dropping table whatever.

6 Last, but not least, be creative, and find more reasons to kill your application, while at the same time giving the same die message on every die statement (once debugging is done). This way if someone is hacking you, you don't give them any feedback that they are getting through some of your obstacles.

If there's an outside chance that the order of [i] is not in a predictable order, or possibly has gaps, but you need to use it as a key:

You should convert your cert and you can use openssl to achieve the conversion that you are wanting.

My solution to this was to add an event handler in the test method, so that when the event is raised, the test method will create a CancelEventAgrs and set its Cancel to True/False.

Cross-platform generally refers to a technology which can be used for multiple operating systems. For example, Mono is an open-source implementation of the Common Language Runtime (CLR), which are the underlying libraries required by .NET.

Mono runs on Linux, BSD, Unix, Mac OS X, Solaris and Windows. Mono itself is not an IDE, but several cross-platform IDEs exist as well. The most popular is MonoDevelop.

Several languages are built on top of the .NET framework such as C# and VB.NET. C# is the most popular for cross-platform development.

I am wanting to write a variety of Perl programs that connect to an SSH server. The server is a Mac, the client is Windows behind an HTTP proxy. PuTTY works perfectly to connect, but executing the Perl scripts isn't ideal, for several reasons.

I want to have an interactive (not with the user, but with the software running on the server) Perl program running on the client and the server, a la how rsync works with the -e option.

First step, how do I connect? I use plink (from PuTTY), which has a variety of useful options... tunneling, running a series of commands, etc. From there, I can easily run commands and scripts on the server and get back the result, process the result, and then do the next command. But this is SLOW because it has to renegotiate the PuTTY/SSH connection each time. Hence the desire for an interactive approach.

When running plink in this manner, I could interact with the plink command, but I'm having trouble with double-piping (input and output, never mind triple-piping to also get STDERR). I tried everything on http://docstore.mik.ua/orelly/perl2/prog/ch16_03.htm and nothing worked. Got various errors, etc.

Next I tried writing my own client/server programs using sockets. Worked pretty well, except for some reason each time I run the SocketServer on the server program and then connect to it (using plink to tunnel localhost to the server's port), the port closes itself off and refuses future connections. So I have to change the port every time, which seems counterproductive (probably an issue with my code, but I don't see it).

The next step was trying Expect.pm. However, that seems to only work under Linux or CYGWIN, which I don't want to get too deep into. This needs to stay native Windows as much as possible.

My latest is looking into Net::SSH::Perl and other SSH modules. I set up a port 22 tunnel with plink and then in CYGWIN I try:

So then I try the following program (again, with the port 22 tunnel established)

(user and pass above are substituted for the real user and pass) I can see the plink tunnel opening the forwarded port, but the program returns

So, this is where I am... I have many more SSH Perl modules to try, but I was wondering if anyone else had this situation. I see tons of people using PuTTY and SSH stuff, but none of them are going through a proxy (and thus NEED PuTTY). And I don't have the time or patience to mess with something like corkscrew, so please let's not go down that particular rabbit hole.

... continuing the journey... the new thing I've tried, and y'all will probably laugh at this bass-ackward solution... I tunneled port 23 through the Mac to a Windows machine on the same network running Telnet. Then, using Net::Telnet I am able to telnet to the Windows machine. Very awkward. I also wanted to be able to establish the tunnel and then kill it at the end of the program, so I added some oddball stuff. Check it out and PLEASE help me get a better solution to this.

The $tunnel thing is the weirdness. plink will establish a terminal session, so I opened a handle to it's STDIN via the pipe. The -L establishes the tunnel. When I'm done with the telnetting, I print "exit" to plink which exits the bash session. I also use the "sleep 7" to give it enough time to establish the session. Ugh! But it seems to work moderately well.

I'm trying to get a multi-auth system working where Users can log in via the normal web portal, but a separate database of entities (named "robots" for example) can also log in via an API guard token driver. But no matter what I do, the setup I have is not directing my authentication guard to the correct Robot database and keeps trying to authenticate these requests as Users via tokens (which fails, because users don't have tokens).

Update: on further inspection, it appears that most of the settings in auth.php are not applying properly - is there some way I can force these settings to take effect?

As of right now, you cannot retrieve a permanent access token. You have 2 options that come close.

The first is to request a "refresh" token when using the standard OAuth flow. That's what you're doing by sending "duration" as "permanent" in your code. The refresh token can be used to automatically retrieve new 1 hour access tokens without user intervention; the only manual steps are on the initial retrieval of the refresh token.

The second alternative, which applies only when writing a script for personal use, is to use the password grant type. The steps are described in more detail on reddit's "OAuth Quick Start" wiki page, but I'll summarize here:

So you just want to exclude files containing backup in their names? This should work:

Re-read the $set documentation https://docs.mongodb.org/v3.0/reference/operator/update/set/ It specifically says it will replace what is there. So it doesn't care if a document exists or not that's why it doesn't return the error. you need additional operators to reject the query if it exists and is the same.

You have to trigger the error in order to know if the DB as the collection already and if it's up to date. So an additional operator is required to check if the collection found already has the updated information. MongoDB uses operators represented with $ so $gt or $lt or $nor (greater than , less than, Select everything but this) there's more but i'll let you explore the possibilities. https://docs.mongodb.org/v3.0/reference/operator/query/nor/

this line needs to trigger the error based on your expressions and operators. when you get that working don't just throw the error allow the program to continue to the next because this error isn't meant to break (throw) on that error it's only there to tell you hey the DB has this and it's updated, and on error will let you know nothing was done.

collection.updateOne(query, {"$set": data},{w: "majority"},function (err,result){ console.error(err);console.log(result); });

I was using IntelliJ with JBoss EAP and it failed like your error (Access Denied). So I turned off my virus protection (MSE), problem was solved.

You should have a look at this great module, async which simplifies async tasks like this. You can use queue, simple example:

It will have a window of ongoing actions and the tasks room will be available for a future task if you only invoke the callback function. Difference is, your code now opens 2000 connections immidiately and obviously the failure rate is high. Limiting it to a reasonable value, 5,10,20 (depends on site and connection) will result in a better sucess rate. If a request fails, you can always try it again, or push the task to another async queue for another trial. The key point is to invoke callback() in queue function, so that a room will be available when it is done.

Simply use echo form_dropdown('school', $school_list, set_value('school', @$school->id));

Then you know by the @ that value may be empty sometimes, and it supresses errors if that value is missing.

Doing this will send a NULL value to the 3rd parameter if you have no id, and it will instead select the first <option> by default.

In Visual Studio, it's possible to use internal modules without having to include /// <reference path="..." /> tags.

In order to "construct the grammar directly in Python", pyparsing needs to read the source file (in this case a matplotlib source file) where the grammar is defined. In what would usually just be a bit of harmless extra work, pyparsing is reading not just the matplotlib source file but everything in the stack at the point the grammar is defined, all the way down to the source file where you have your import matplotlib. When it reaches your source file it chokes, because your file indeed is not in UTF-8; 0x96 is the Windows-1252 (and/or Latin-1) encoding for the en dash. This issue (reading too much of the stack) has already been fixed by the author of pyparsing so the fix should be in the next release of pyparsing (probably 2.1.8).

By the way, matplotlib is defining a pyparsing grammar in order to be able to read fontconfig files, which are a way of configuring fonts used mainly on Linux. So on Windows pyparsing is probably not even required to use matplotlib!

ArrayOps.drop internally calls IterableLike.slice, which allocates a builder that produces a new Array for each call:

You're seeing the cost of the iteration + allocation. You didn't specify how many times this happens and what's the size of the collection, but if it's large this could be time consuming.

One way of optimizing this is to generate a List[String] instead which simply iterates the collection and drops it's head element. Note this will occur an additional traversal of the Array[T] to create the list, so make sure to benchmark this to see you actually gain anything:

Another possibility is to enrich Array[T] to include your own version of mkString which manually populates a StringBuilder:

I've still not quite got a complete understanding of promises so apologies if this is a simple misunderstanding.

I have a function for deleting an item on a page but I have a specific behaviour depending on the state of the page. Psuedo code-wise it's something like this:

Hopefully that makes sense. Essentially if there are changes, the data must be saved first. Then if the data has been saved, or if there were no changes to begin with, prompt the user to confirm deletion. The problem is I'm using durandal and breeze, and I can't seem to chain the promises they return together correctly.

My function currently looks like this, which I know is wrong, but I'm struggling to work out where to fix it.

The app.showMessage call from durandal returns a promise, then the this.save returns a promise, and finally the this.refresh also returns a promise.

So I guess I need to check the hasChanges, then if necessary call save, and resolve it. Then after that conditional section has finished resolving, call the second prompt, and then resolve all the promises within that.

I'm sorry I don't think this is super clear, but that's also I think coming from the fact I'm not completely following the chains here.

I need to build a query that will aggregate the # of units of blood that has been transfused so it can be compared to the # of units of blood that has been cross-matched. Blood (a precious resource) that is cross-matched, but not transfused is wasted.

Providers are supposed to check the system-of-record (Epic) for 'active' cross-match orders before creating new ones. Providers that don't do this are 'penalized' (provider 20). No penalty applies (it seems) for providers that don't transfuse all of the blood that they've cross-matched (provider 10).

I am trying to understand the difference between CursorTypeEnum 0 and 3, as described here. Both are static, except type 0 only supports forward iteration.

In my case rs.Open strsql, cn, 0 returns consistently in under 30 seconds, whereas performance of the same query with type 3 cursor fluctuates widely between 3 and 8 minutes.

They both need to lock the underlying tables in order to create static set, so why such dramatic difference?

Is there a way to convert it to this with Pure JavaScript (and without frameworks like jQuery) without using eval?:

What have i tried so far

What I'm trying to do is have an EditText where people enter their names. As people press the "Add Player" button, the name which they just typed appears below in the list form. So I've created 8 textviews which are initially invisible but as people type the name press the "Add Player" button, the text changes to their names and becomes visible.

However, with this, whenever I press the "add player" button, the app crashes and I get a NullPointerException. How would I solve this?

The problem isn't with the for loop as the app crashed without it. The problem seems to be with the array as if I put

I currently need two channels of unsigned char to contain my data. But at one point i need to split my data to process them separately (which probably results in a matrix copy)

My question is the following : Should I use two different matrix at the beginning to avoid the split or let it like this ? Or as it may depend on my computation what is the difference of cost between two accesses of a matrix and a matrix copy ?

I just added "-с" parameter. It makes Psexec copy executable to remote machine. So it works without access errors.

Absolutely positioned elements are removed from the normal document flow, so they won't fill up 100% of their parent like regular static block level elements. Instead, they rely on their content width or a specified width. Firefox seems to apply the content width a bit differently than Chrome or IE, which is why it appears cut off.

I am trying to write an x86 emulator in JavaScript for education purposes. I have already written a compiler and at the moment I am trying to write the x86 emulator in JavaScript.

I have however a problem with the DIV instruction. According to http://siyobik.info/index.php?module=x86&id=72 DIV takes a 64bit number as input by interpreting EDX as the higher 32bit and EAX as the lower 32bit. It then divides this number by the DIV parameter and puts the result (if it is not greater than 0xFFFFFFFF) into EAX and the remainder into EDX.

As JavaScript does not support 64bit integer I need to apply some tricks. But so far I did not come up with something useful.

Does someone here have an idea how to implement that correctly with 32bit arithmetic?

One data.table way of indexing a column by number would be to convert to a column name , convert to an R symbol, and evaluate:

But this is not really an approved path to success because of the DT FAQ #1 as well as the fact that row numbers are not considered as valid targets. The philosophy (as I understand it) is that row numbers are accidental and you should be storing your records with unique identifiers.

You can only have one element with an ID. Change them to classes, and you'll need to do some tree traversing to get the reference to the correct form elements to show and hide http://jsfiddle.net/pcUBr/

This answer points out the fact that C++ is not well suited for the iteration over a binary file, but this is what I need right now, in short I need to operate on files in a "binary" way, yes all files are binary even the .txt ones, but I'm writing something that operates on image files, so I need to read files that are well structured, were the data is arranged in a specific way.

I would like to read the entire file in a data structure such as std::vector<T> so I can almost immediately close the file and work with the content in memory without caring about disk I/O anymore.

Right now, the best way to perform a complete iteration over a file according to the standard library is something along the lines of

or use std::copy, but even with std::copy you are always using istreambuf iterators ( so if I understand the C++ documentation correctly, you are basically reading 1 byte at each call with the previous code ).

So the question is: how do I write a custom iterator ? from where I should inherit from ?

I assume that this is also important while writing a file to disk, and I assume that I could use the same iterator class for writing, if I'm wrong please feel free to correct me.

Like you said, after navigating away from original page you're losing track of what windows you may have opened.

As far as I can tell, there's no way to "regain" reference to that particular window. You may (using cookies, server side session or whatever) know that window was opened already, but you won't ever have a direct access to it from different page (even on the same domain). This kind of communication between already opened windows may be simulated with help of ajax and server side code, that would serve as agent when sharing some information between two windows. It's not an easy nor clean solution however.

The keydown event supports event bubbling, so you can just add the handler to the container element like

For example, the link below triggers something in jQuery but does not go to another page, I used this method a while back ago.

Notice theres a just a hash tag there, and usually causes the page to jump when clicked on, right? [I think]. It is only for interactive stuff, doesn't go to another page or anything else. I see a lot of developers do this.

I feel like its the wrong thing to do though. Is there another recommended way to do this without using HTML attributes a way where it is not suppose to be used?

There are two plugins/listeners that will generate this directly within JMeter UI or write the files to results if you are doing distributed test. Both are from the Extras Set.

Plugin installation is described here, it is as simple as copying files into your JMeter installation.

This is a shot in the dark, but try return false after the trigger reset and the alertify success stuff.

I am converting html into pdf. It is working fine. but when i try to save html into any location it gives me error Network path not found. I am having some line of code

Provided that PreCalcCurrentMonth is a Date variable, try something like this (untested):

Format(PreCalcCurrentMonth,"\#mm\/dd\/yyyy\#") ensures that your date is converted to a string in US date format #mm/dd/yyyy#, whatever your regional settings. # is the date separator.

Instead of %ProgramFiles%, isn't there a %Programfiles(x86)% that always goes where you want, regardless of which cmd.exe is running? My XP-64 systems all have that; excuse me for not taking the time to boot up a Vista system.

I am trying establish a connection to my redshift database after following the example provided by AWS https://blogs.aws.amazon.com/bigdata/post/Tx1G8828SPGX3PK/Connecting-R-with-Amazon-Redshift. However, I get errors when trying to establish the connection using their recommended driver. However, when I use the Postgre driver I can establish a connection to the redshift DB.

AWS says their driver is "optimized for performance and memory management", so I would rather use it. Can someone please review my code below, and let me know if they see something wrong? I suspect that I am not setting the URL up correctly, but not sure what I should be using instead? Thanks in advance for any help.

Given that characters can take a variable number of bytes this would be pretty tough to do without converting the bytes to characters with a TextReader.

You could wrap up a TextReader and give it a Seek method that ensures enough characters have been loaded to satisfy each request.

The logical density of the display is given in the DisplayMetrics class, and can be retrieved with,

it appears that var is None in what you provided. Everything is correct, but var does not contain a string.

I have an ajax request that fetches some data and returns a html response that I print out on the page. The problem is that for some reason the html response doesn't get printed, only textual data does. The correct response is being returned as I've checked in the browser console.

The right response comes back but it doesn't print the html on the page. Anyone know why this is?

I think you have a problem with quotes in your statement text. Look at this excerpt based on your code when I tested in the Immediate window:

That can't be right. And when Access tries to execute the query and sees intYear, it interprets that to be a parameter because the db engine knows nothing about a VBA variable named intYear.

I encourage you to follow KevenDenen's advice to add Debug.Print strCount2 to the code after it has finished building the strCount2 string. Then you can run the code and view the text of the completed statement in the Immediate window. (You can use Ctrl+g to go to the Immediate window.) It helps tremendously to examine the actual statement your code is asking Access to execute.

No, this is not possible. There is no API to programatically set the user's alarm.

However, you can invoke the clock application to a specific view-state (alarm screen) and allow the user to set the alarm themselves.

Correct, it's still not kosher. It will cause warnings in many browsers about "mixing secure and insecure content."

Hi guys i need to integrate drscheme into my c# code for my assignment but i could find any luck on the web. Can anyone help me ? I tried ironscheme but got the following error.

I am customizing a blog for a friend of mine. When it loads, I want all the img's in each post to have a max-width and max-height of 150px. When the user pushes the img, the max-values should increase to 500px, which is easy enough. The problem with my code is that I can't get an animation on it, which I want. Any help out there?

I've created an overly complex solution that allows you to create a helper function to do an inline type of rang value finder. The ranger function takes the cut points you want to split on and then returns a function that will choose the value of the parameter based on which interval it falls. It primarily uses findInterval but unfortunately you inequalities don't exactly line up with how findInterval likes to do them so I had to do some fiddling.

So while it may not be the best choice in this case, i might be useful if you have a bunch of different ranges or something like that.

Whenever I try to upload files I get a blank white screen with the following PHP error:

I have a deployment project in visual studio 2008 that installs several C# projects. Among other things, I'd like it to write projects assembly version to registry.

Is there a way to automatically find out whats the projects assembly version (written in AssemblyInfo.cs) and write that as value of a registry property?

If not, is there any way to do this better than by hand? It is important that these values are correct because they are used by our updating software.

EDIT: I'm not sure I was completely clear in my question. I don't want to get this number and store it to a string. I want to write it to registry with Deployment Projects Registry Editor (not sure if that's the official name, you can get to it by right clicking the deployment project in solution explorer and navigating to View->Registry)

You can change offset and width of your toolbar, if you want to use customview (initWithCustomView)

The layer you are looking for is https. Just make sure the requests go over https if the data is sensitive.

Look at the SQL debug output, the regions are being retrieved using separate queries, that's how Cakes ORM currently works.

Here's an (untested) example, it adds a belongsTo association with the foreignKey option set to false in order to disable the automatic foreign key generation by the ORM, this is necessary as it would otherwise look for something like Profile.region_id. Note that consequently the contain config has to be changed too!

That should generate a proper query that includes the stores as well as the regions table, making it possible to sort on Region.name. Note that the resulting array will be a little different, Region will not be nested in Store, everything will be placed in the same level, ie:

Either you modify your view code accordingly, or you transform the retrieved data before passing it to the view. A third option would be to include a nested Region in the contain config, however that would result in additional queries that are totally unnecessary as the data was already fetched with the main query, so I wouldn't recommend that.

Set the initial values for the select and radio inputs in the controller itself. E.g.

I have a small application where I'm getting translations json for a locale and updating Ember.STRINGS. Am I doing something wrong?

; and it seemed to work. When I changed it to 1.0.0 a lot of things started crashing around. Both of these don't work.

Why do you want to know, what kind of database field you are using? Are you storing information from the form through raw sql? You should have some model, that you are storing information from the form and it will do all the work for you.

Maybe you could show some form code? Right now it's hard to determine, what exactly you are trying to do.

It's not ideal but I compare the page text against following regex since on my setup that text accompanies web page errors:

According to a similar discussion, you can create a UICONTROL pushbutton which has the advantage that it accepts HTML input string. Then using FINDJOBJ, we can fake the look of a clickable hyperlink:

If you want a designed select I'd suggest you use jQuery then find a good plugin for customizing select boxes, try Googling "jquery design select". Have never used a jQuery plugin for this but I know they exist.

Don't use the session!!! If the user opens a second tab with a different request the session will be reused and the results will not be the ones that he/she expects. You can use a combination of ViewState and Session but still measure how much you can handle without any sort of caching before you resort to caching.

As a lot of people have suggested, Resource Leaks are fairly easy to cause - like the JDBC examples. Actual Memory leaks are a bit harder - especially if you aren't relying on broken bits of the JVM to do it for you...

The ideas of creating objects that have a very large footprint and then not being able to access them aren't real memory leaks either. If nothing can access it then it will be garbage collected, and if something can access it then it's not a leak...

One way that used to work though - and I don't know if it still does - is to have a three-deep circular chain. As in Object A has a reference to Object B, Object B has a reference to Object C and Object C has a reference to Object A. The GC was clever enough to know that a two deep chain - as in A <--> B - can safely be collected if A and B aren't accessible by anything else, but couldn't handle the three-way chain...

I am learning Python, and currently working on reading in a file, splitting the lines and then printing specific elements. I am having trouble splitting multiple times though. The file I am working on has many lines that look like this

I am trying to split it, first by tab and newline "/t/n", and then split the elements with |, I have tried .split and .strip and am not having much luck. I figured maybe if I just worked on a single line I could get the idea down, and then modify it into a loop that would access the file

This is what I did just to try to strip the whitespace and the tabs, then to split on | but it doesn't seem to do anything. Eventually my desired output from this single string would be

Instead of release() and create() the mediaplayer object every time user clicks the button, try to create() only once. Then inside of onClick(), try seekTo(0) to rewind from the beginning of the media file, then call start() to play again.

Roughly, Magento is creating an order collection for you and attempting to load all the records. This collection has a rule that only allows it to create one order object for each ID, so when your additional object is loaded an exception is thrown.

The left joins could be the issue, but it's hard to say off the bat. Could you post a little detail on how you are making the API call? An incorrect join can often have this problem.

If you're using the default code, my first guess would be that there are erroneous records in the database, or that this is an upgraded Magento system which had a bad upgrade in the past. Try this on a clean copy of your EE version pointing to the same database. If the same problem occurs, you may need to spelunk in the database looking for the reason for the problematic data load. Since you already have the query, you may want to separate out parts of the query to see if some subquery is returning too much data.

I know you said there's no dangling extern "C"... But why would that even be an issue given how you are compiling with gcc and not g++??? (Which will, in fact, happily treat smsdk_ext.cpp as a C and NOT C++ file... With all the errors and pain that come from doing so...)

Often you will see such error messages when the wrong include files are tagged extern "C". (Or not properly tagged as the case may be.)

Alternatively, another approach is to start with a minimal Hello World program and see if that compiles. Then build up, including what you need to, until you hit a problem. (Or take the existing software and simplify it down until you find the problem area. Start with one "g++" line, copy the file, and pare it down until the problem goes away. Perhaps you have a #define or typedef that conflicts with something in a system file.)

I'm developing a GWT application witch reads and displays videos from youtube. With that purpose in mind I started using gwt-youtube-api.

I can display a player and play the video from youtube accordingly but I'm unable to search videos on youtube.

The following code should retrieve the most recent videos from youtube, but it doesn't do anything. After making RPC call I can't see any results for both onSucess and onFailure:

First, this function is called many times. It should be noted that wString[] does contain the character constant '\n'.

At the end, a WM_PAINT message is sent while nLines should be non-zero since log contains multiples '\n'. My WndProc receives the message and processes it.

For some reason, in the OnRender function, nLogLines' value is 0. What is wrong?

You could allow every subdomain in the first place and then check if the subdomain is valid. For example:

I'm performing some computations in C with floating point numbers. I'm specifically dealing with the case where I get the lowest possible single precision value for the exponent.

Say my exponent is -126 and I have to decrement it. In this case, I can't go any lower, so I need to right shift my mantissa once. I know I'm supposed to get the exact answer for a calculation and then round (to whatever place is specified).

I'd give this a shot http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js">

Not sure if your intent was to pass the entire response object to the directive, but response.data is the location of what you're likely expecting back from the ajax call.

Aside from that I would make sure that your object structure is correct. Or if you're returning an array that you set that flag in the $http call.

when a link was clicked using php

I would like to ask some help on this thing. I created a site that has a lot of div and what I want is that when a link is clicked only one div will be displayed without reloading the whole page.

Sample code:

<ul> <li><a href="">Div 1</a></li> <li><a href="">Div 2</a></li> <li><a href="">Div 3</a></li> </ul> <div id="content1"> <p>This is content 1</p> </div> <div id="content2"> <p>This is content 2</p> </div> <div id="content3"> <p>This is content 13</p> </div>

Is it possible if I'll just use php? And please help me on how I will do it.

13646954 1 swig generated code, generating illegal storage class for python wrapper of C++ API

I'm trying to take the approach of using swig with the main header file. It seems like swig will work doing this, but I've run into some problems. I asked a first question about it here on stackoverflow and while I haven't yet been successful, I've made enough progress to feel encouraged to continue...

So now, here's my interface file:

/* File : myAPI.i */ %module myAPI %{ #include "stdafx.h" #include <boost/algorithm/string.hpp> ... many other includes ... #include "myAPI.h" #include <boost/algorithm/string/predicate.hpp> #include <boost/filesystem/path.hpp> #include <boost/filesystem/operations.hpp> using boost::format; using namespace std; using namespace boost::algorithm; using namespace boost::serialization; %} /* Let's just grab the original header file here */ %include "myAPI.h"

As far as I can tell swig runs just fine. However, in the generated code it produces numerous definitions like this one:

SWIGINTERN int Swig_var_ModState_set(PyObject *_val) { { void *argp = 0; int res = SWIG_ConvertPtr(_val, &argp, SWIGTYPE_p_MY_API, 0 | 0); if (!SWIG_IsOK(res)) { SWIG_exception_fail(SWIG_ArgError(res), "in variable '""ModState""' of type '""MY_API""'"); } if (!argp) { SWIG_exception_fail(SWIG_ValueError, "invalid null reference " "in variable '""ModState""' of type '""MY_API""'"); } else { MY_API * temp; temp = reinterpret_cast< MY_API * >(argp); ModState = *temp; if (SWIG_IsNewObj(res)) delete temp; } } return 0; fail: return 1; }

Visual Studio 2010 complains with an error for each of these code blocks. The error is based on the temp var:

2>c:\svn\myapi\myapi_wrap.cxx(3109): error C2071: 'temp' : illegal storage class

I tried just to add a global declaration of this variable as an int to the swig generated _wrap.cxx file, but it didn't not work. (clearly a naive approach...).

Does anyone have some insight as to what I need to do to avoid this error?

Thanks in advance!

Note change event fires after the input loses focus. You may want to use input event instead.

To convert the string to numbers, you can use the unary operator + instead of Number.

To default to 0 when some expression is falsy, you can use expr || 0.

var field1 = document.getElementById('field1'), field2 = document.getElementById('field2'), total = document.getElementById('total'); field1.oninput = field2.oninput = function updateTotalCosts() { total.value = (+field1.value || 0) + (+field2.value || 0); };

<input id="field1" /> + <input id="field2" /> = <input id="total" />

Or, using jQuery,

var $field1 = $('#field1'), $field2 = $('#field2'), $total = $('#total'); $field1.add($field2).on('input change', function updateTotalCosts() { $total.val((+$field1.val() || 0) + (+$field2.val() || 0)); });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <input id="field1" /> + <input id="field2" /> = <input id="total" />

You've an answer how to do this with XML::Simple already. But I'd suggest not, and use XML::Twig instead, which is MUCH less nasty.

Why is XML::Simple "Discouraged"?

I'm going to assume that your XML looks a bit like this:

<opt Timeout="5"> <Roots> <Root Action="Reject" Interval="Order" Level="Indeterminate" Name="Sales"> <Profiles> <Profile Age="50" Name="Bill" Status="Active" /> <Profile Age="24" Name="Bob" Status="Inactive" /> </Profiles> </Root> </Roots> </opt>

I can't tell for sure, because that's the joy of XML::Simple. But:

#!/usr/bin/env perl use strict; use warnings; use XML::Twig; my $twig = XML::Twig -> new -> parsefile ( $configfile ); print $twig -> get_xpath ( '//Profile[@Name="Bob"]',0 ) -> att('Status')

This uses xpath to locate the attribute you desire - // denotes a 'anywhere in tree' search.

But you could instead:

print $twig -> get_xpath ( '/opt/Roots/Root/Profiles/Profile[@Name="Bob"]',0 ) -> att('Status')

Much simpler wouldn't you agree?

Or iterate all the 'Profiles':

foreach my $profile ( $twig -> get_xpath ('//Profile' ) ) { print $profile -> att('Name'), " => ", $profile -> att('Status'),"\n"; }

Due to unsuccessful registration, the details do not get entered into the database. After searching a bit, found out the problem as the ip address.

You can add functions to Studio by putting PHP files with stub function descriptions into special directory. Find this directory in filesystem in a following way: write something like gmdate(), select the name and press F3. You will be taken to one of the prototype files. Note the directory where this file resides (shown on the top and if you hover over the tab). Now you need to create stubs for functions you are missing just like the one you're looking at. You can put them into any file, generally, but I suggest putting them into separate file - like geoip.php - and put this file into that directory. You may also want to do right-click/Show In/PHP Explorer and browse other prototype files if you need examples of how to do it right.

1104625 0 Cruisecontrol, deployment, folder permissions

We're using cruisecontrol.net, it builds the version, creates a zip file, then 15 min later, unzips the file on the Integration server. But when the folder gets to the integration server, often, the security permission on one of the folders is totally hosed. The Domain admin and folder owner can't even open the folder in explorer. We reboot and the folder permissions are good we can delete the folder and redeploy the zip file and it's okay.

Does anyone have any idea what or how the folder permissions are getting so messed up? Any tools to use to diagnose/watch what exactly is messing it up?

But what I got is the confirm box never show up, and it returns true (and go to next page). So, how to change this condition so my confirmation box showed up first, then after click OK, it go to next page, and if CANCEL, do nothing?

39601609 0 Angular 2 - cant load demo libraries (Visual Studio 2015)

OK I am stumped: Is there a basic, minimal, working Angular 2 tutorial for Visual Studio 2015 that actually works?

I've attempted numerous tutorials including the official one: https://angular.io/docs/ts/latest/cookbook/visual-studio-2015.html

Believe it or not, at the time of writing this post this example does not work - throws a 404 for numerous dependencies referenced in the NPM package.json file (as for the others tuts, well they reference a lot of beta removed or non-existing references).

I mean, where do you actually download Angular 2 Typings from? They are certainly not listed with the rest of the library on the official site: https://code.angularjs.org/

It actually seems to be impossibly complicated to create an Angular 2 application in Visual Studio that does not require a mass of dependencies and actually works.

Is it just me or are other members of the VS dev community experiencing the same?

From the top of my mind:

void * const var; // The pointer is constant and var can change const void * var; // The pointer can change but not var

so I would think that your syntax

const void * const *ptr;

means that ptr is a pointer to a pointer. So ptr would point to an address and that address cannot change (the first const). Also the address that ptr is located cannot change (the second const). But I am not totally sure of this.

5089719 0 from facebook, i want to fetch Hometown details . from it i want to saparate city,state, country

From facebook, i want to fetch Hometown details . from it i want to separate city,state, country. These fields are separated by comma. so i can split them by comma.

my problem is: as soon i enter city name in hometown field of facebook, it is giving combination of city,state and country. but sometime it is giving combination of city and country so, when i split this string by comma, how to i know that second element is state or country.

I can do one thing, i can check the length of array, if it has three filed then it has city/state/county. else city/county.

Is this ture? can it have more files.

The cross section is just a line graph (or two) overlayed on your original chart.

671136 0 Wrap NSButton title

Any way to have a NSButton title to wrap when it's width is longer than the button width, instead of getting clipped?

I'm trying to have a radio button with a text that can be long and have multiple lines. One way I thought about having it work is to have an NSButton of type NSRadioButton but can't get multiple lines of text to work.

Maybe my best alternative is to have an NSButton followed by an NSTextView with the mouseDown delegate function on it triggering the NSButton state?

Yes, though you need to get familiar with the Team Foundation Server command line tf.exe.

See the post I did about this a while ago here http://www.woodwardweb.com/vsts/unlocking_files.html

Since I wrote that post (in October 2005) some alternatives have come about for people who don't want the hassle of learning a new command line.

You could install the TFS 2008 Power Tools on top of Visual Studio 2008 SP1 and you are able to do some of this from the UI in Visual Studio (Right click on the Developer in the Team Members node installed by the power tools and select "Show Pending Changes" and then "Undo..."

Alternatively, install the excellent (and free) TFS Sidekicks from Attrice.

Good luck.

-(void)methodA { if(!isKeyBoarHidden){ [textField resignFirstResponder]; } else{ //code here } } - (void)keyboardHidden:(NSNotification *)notification { isKeyBoarHidden = YES; [self methodA]; }

sometime it may be helpful if we have some local variables inside methodA and we dont need to make variables global.

As a starting point I'd look at the WinSock API. You may find a way of pulling traffic information on a per process basis. If you want to see total network usage, I'd use the Performance Monitoring tools. I found this example from a web search:

private static void ShowNetworkTraffic() { PerformanceCounterCategory performanceCounterCategory = new PerformanceCounterCategory("Network Interface"); string instance = performanceCounterCategory.GetInstanceNames()[0]; // 1st NIC ! PerformanceCounter performanceCounterSent = new PerformanceCounter("Network Interface", "Bytes Sent/sec", instance); PerformanceCounter performanceCounterReceived = new PerformanceCounter("Network Interface", "Bytes Received/sec", instance); for (int i = 0; i < 10; i++) { Console.WriteLine("bytes sent: {0}k\tbytes received: {1}k", performanceCounterSent.NextValue() / 1024, performanceCounterReceived.NextValue() / 1024); Thread.Sleep(500); } }

SQLite doesn't have any built in boolean type. You need to handle it yourself. I typically use and integer value instead and set it equal to 1 or 0 for true or false. Then if you want to check if it is true in the DB you check if the value is 1, etc.

Solution is to ditch the join table and have a direct reference between Test <> Team.

The SQL you are seeing makes sense as Hibernate cannot know that TestTeam will be the same entity referenced by Test and Team.

Test test = .../ test.getTestTeam();//triggers load **where test_id = test.id** Team team = test.getTestTeam().getTeam(); team.getTestTeam();// triggers load **where team_id = team.id**

runtime.Stack() puts a formatted stack trace into a supplied []byte. You can then convert that to a string.

You can also use debug.Stack(), which allocates a large enough buffer to hold the entire stack trace, puts the trace in it using runtime.Stack, and returns the buffer ([]byte).

I guess you may be seeing a NPE, as you may be violating the paragraph you were citing:

String custData = custFacade.find(customerId).toString();

The find seems to implicitly querying for the object (as you describe), which may not be fully synced to the database and thus not yet accessible.

10618822 0 JavaScript doesn't append script

I'm using "PHP Form Builder Class" to generate form and submit it with ajax, but i dont think problem is related to "PHP Form Builder Class".

I`m loading form and "PHP Form Builder Class" is generating javascript that binds some events to submit action, and jquery-ui button etc.

When i submit form and get response from server (html+javascript) then i empty container and load new data - with the same form (to show errors or submit new one).

Problem is that second time it wont bind any events to my form.

I have removed all events from previous html code, before deleting it and adding new one.

So now to the weird part - when i insert new html and js into my container it wont show that particular javascript code that is intended for form. I cant see it in html DOM anywhere when inspecting. I added simple alert(1) in it to check if it will run, and it does, although rest of the code doesnt - and i dont get any errors. So how can this alert run when it doesn't show in dom. I'm appending code with jquery.html()

I know its not easy to understand my problem, but i hope someone will

The only thing that sticks out is "&" which is + in SQL Server. However, & in access also treats NULL values as the empty string, which needs further processing with ISNULL in SQL Server:

SELECT table1.* FROM table1 INNER JOIN (table2 INNER JOIN table3 ON ( table2.custkey = table3.custkey ) AND ( table2.sequence = table3.sequence )) ON table1.account = table2.account WHERE (( LEFT(table2.keyid, 1) = 'B' )) ORDER BY isnull(table3.lastname,'') + isnull(table3.firstname,''), table1.account;

If I were to write the query in SQL Server from scratch, I would probably do the joins serially rather than do the t2-t3 in a bracket before joining back to t1. The test for the first character would also be expressed as LIKE (a personal preference).

 SELECT table1.* FROM table1 JOIN table2 ON table1.account = table2.account JOIN table3 ON table2.custkey = table3.custkey AND table2.sequence = table3.sequence WHERE table2.keyid LIKE 'B%' ORDER BY isnull(table3.lastname,'') + isnull(table3.firstname,''), table1.account;

because your .column divs are float:left; you need a container with clear:both; after the columns:

<section> <h4>WHAT WE DO</h4> <h2>HEADING</h2> <div class="column"> <div class="item"></div> <h3>ITEM1</h3> <p>Necessitatibus ipsa ex hic sunt maxime.</p> </div> <div class="column"> <div class="item"></div> <h3>ITEM2</h3> <p>Molestias ipsum ex deleniti illo qui obcaecati repellat.</p> </div> <div class="column"> <div class="item"></div> <h3>ITEM3</h3> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p> </div> <div class="clearer"></div> </section>

.clearer { clear:both; }

I've used (and modified) Tim Tripcony's Java objects in his "Using Java in XPages series" from NotesIn9 (the first is episode 132. The source code for what he does is on BitBucket. This basically converts the dominoDocument to a Map. It doesn't cover MIME (Rich Text) or attachments. If it's useful, I can share the amendments I made (e.g. making field names all the same case, to ensure it still works for existing documents, where fields may have been created with LotusScript).

If what you're talking about is the space in between each box, the class "box" is inline-block, so the line-breaks in the markup are interpreted as implied spaces. Place all the inline-block markup on a single line <div></div><div></div>... and the "space" between will collapse.

I am new to the whole GWT thing and for a project I need to read a serverside file via an asynchronous call and return an array of data to the client. So far I followed an RPC tutorial and implemented the server and client side code as well as the web.xml file but when I try to RPC the DataExtraction method on my client, it will result in the following error:

javax.servlet.ServletContext log: Exception while dispatching incoming RPC call com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract int[] ch.uzh.ifi.se.swela.client.DataExtractorService.extract(java.lang.String) throws java.io.IOException' threw an unexpected exception: java.security.AccessControlException: access denied ("java.io.FilePermission" "/SE Swiss Election App/war/tables/Ferien_K.csv" "read")

This is the call:

DataExtractorServiceClientImpl clientImpl = new DataExtractorServiceClientImpl(GWT.getModuleBaseURL() + "dataExtractor"); clientImpl.extract("/SE Swiss Election App/war/tables/Ferien_K.csv");

For me it seems like, that the server does not have the permission to open the file, but how would I fix that? Thank you in advance.

Without knowing the contents of 'BBnormalLinks.txt' or the final value of $rand_link, it is difficult to say precisely what is going wrong.

Your usage of file() and mt_rand() appear to be correct, though you aren't doing anything to ensure that you are getting a valid URL.

This is purely conjecture, but I suspect that you don't have PHP properly configured to display errors. If the file fails to load, $links will have a null value going into your penultimate line. You will then try to access element 0 of a null array and receive an empty value. This will result in header('refresh:2;url=') and your page will simply refresh itself every 2 seconds.

Unwind has it right, except you should use 'sendto'

Here is an example, that assumes you already have a socket. It was taken from clamav

static void broadcast(const char *mess) { struct sockaddr_in s; if(broadcastSock < 0) return; memset(&s, '\0', sizeof(struct sockaddr_in)); s.sin_family = AF_INET; s.sin_port = (in_port_t)htons(tcpSocket ? tcpSocket : 3310); s.sin_addr.s_addr = htonl(INADDR_BROADCAST); cli_dbgmsg("broadcast %s to %d\n", mess, broadcastSock); if(sendto(broadcastSock, mess, strlen(mess), 0, (struct sockaddr *)&s, sizeof(struct sockaddr_in)) < 0) perror("sendto"); }

@m_UserIdList is a VARCHAR(500), not a list of values, so this will not work. You can try and parse the passed in string into a table (and there are plenty of ways of doing so - just search this site).

However, since you are using SQL Server 2008, you should take a look at table valued parameters - these allow you to pass a table of values to a stored procedure.

9471576 0 Extract first word in a SQLite3 database

I have a SQLITE3 database wherein I have stored various columns. One column (cmd) in particular contains the full command line and associated parameters. Is there a way to extract just the first word in this column (just before the first space)? I am not interested in seeing the various parameters used, but do want to see the command issued.

Here's an example:

select cmd from log2 limit 3;

 user-sync //depot/PATH/interface.h user-info user-changes -s submitted //depot/PATH/build/...@2011/12/06:18:31:10,@2012/01/18:00:05:55

From the result above, I'd like to use an inline SQL function (if available in SQLITE3) to parse on the first instance of space, and perhaps use a left function call (I know this is not available in SQLITE3) to return just the "user-sync" string. Same for "user-info" and "user-changes".

Any ideas?

Thanks.

I experienced the same thing. An alternative would be to add a Label control and set the properties on that instead.

Rather than using a BoundField, use a TemplateField. Assuming that your data is returning an indexable item:

<asp:GridViewControl runat="server" ID="GridView2" AutoGenerateColumns="false"> <asp:BoundField HeaderText="Field0" DataField="[0]" /> <asp:BoundField HeaderText="Field1" DataField="[1]" /> <asp:TemplateField HeaderText="Monkey1" /> <asp:TemplateField HeaderText="Monkey2" /> </asp:GridViewControl>

Then in the code-behind:

protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { var data_item = e.Row.DataItem; // Can use "as <type>;" if you know the type. if (data_item != null) { for (int i = 2; i <= 3; i++) { var cell_content = new Label(); e.Row.Cells[i].Controls.Add(cell_content); cell_content.Text = data_item[i]; if (data_item[i].Contains("monkey")) { cell_content.Attributes.Add("class", "monkey bold"); } else { cell_content.Attributes.Add("class", "nomonkey bold"); } } }

Of course an alternative would be to add the Label in the TemplateField -> ItemTemplate declaration with an ID and use "Cells[i].FindControl("label_id")".

I'd strongly recommend using the C99 <stdint.h> header. It declares int32_t, int64_t, uint32_t, and uint64_t, which look like what you really want to use.

EDIT: As Alok points out, int_fast32_t, int_fast64_t, etc. are probably what you want to use. The number of bits you specify should be the minimum you need for the math to work, i.e. for the calculation to not "roll over".

The optimization comes from the fact that the CPU doesn't have to waste cycles realigning data, padding the leading bits on a read, and doing a read-modify-write on a write. Truth is, a lot of processors (such as recent x86s) have hardware in the CPU that optimizes these access pretty well (at least the padding and read-modify-write parts), since they're so common and usually only involve transfers between the processor and cache.

So the only thing left for you to do is make sure the accesses are aligned: take sizeof(int_fast32_t) or whatever and use it to make sure your buffer pointers are aligned to that.

Truth is, this may not amount to that much improvement (due to the hardware optimizing transfers at runtime anyway), so writing something and timing it may be the only way to be sure. Also, if you're really crazy about performance, you may need to look at SSE or AltiVec or whatever vectorization tech your processor has, since that will outperform anything you can write that is portable when doing vectored math.

Most people would prevent the form from submitting by calling the event.preventDefault() function.

Another means is to remove the onclick attribute of the button, and get the code in processForm() out into .submit(function() { as return false; causes the form to not submit. Also, make the formBlaSubmit() functions return Boolean based on validity, for use in processForm();

katsh's answer is the same, just easier to digest.

Looking at your desired output, you are looking for the crossprod function:

crossprod(table(test1)) # product # product p1 p2 p3 p4 # p1 4 1 1 0 # p2 1 3 1 0 # p3 1 1 4 1 # p4 0 0 1 2

This is the same as crossprod(table(test1$user, test1$product)) (reflecting Dennis's comment).

As far as syntax goes, you can use the null-coalescing operator if you want to be fancy, but it's not necessarily as readable.

get { return notes ?? (notes = CalcNotes()); }

Not with the default Route class, but you can make your own route class by deriving from RouteBase. You basically end up having to do all the work yourself of parsing the URL, but you can use the source from Route to help you get started.

14975130 0 iOS crash logs printed to console

My problem appeared when iOS 6 was introduced, but now seems to affect 5.1.1 too.

When the app crashes, the log is printed to the 'Console' and no 'Device Logs' is saved. This is frustrating in so many ways:

console view is too short and all I can see is the log's tail,
copy/paste doesn't work, save to file... produces garbage, it is unusable,
there is no way to preserve logs, symbolicate it, or do anything.

It may be worth mentioning, that we work with accessories and have no way to connect debugger at the same time.

An idea how to fix this would save my day, but any decent workaround will be good too.

Thank you

EDIT: 'Console' and 'Device Logs' are the ones I get in the Organizer.

20134891 0 SKPhysicsBody bodyWithPolygonFromPath memory leaks

I have a strange memory leaks when creating Sprite Kit physics bodies with custom shapes. This is how my implementation looks:

CGFloat offsetX = self.frame.size.width * self.anchorPoint.x; CGFloat offsetY = self.frame.size.height * self.anchorPoint.y; CGMutablePathRef path = CGPathCreateMutable(); CGPathMoveToPoint(path, NULL, 4 - offsetX, 3 - offsetY); CGPathAddLineToPoint(path, NULL, 66 - offsetX, 3 - offsetY); CGPathAddLineToPoint(path, NULL, 35 - offsetX, 57 - offsetY); CGPathCloseSubpath(path); self.physicsBody = [SKPhysicsBody bodyWithPolygonFromPath:path]; CGPathRelease(path);

Everything is going on inside SKSpriteNode method. Instruments tells me about several memory leaks after creating such bodies:

Leaked object: Malloc 32 Bytes Size: 32 Bytes Responsible Library: PhysicsKit Responsible Frame: std::__1::__split_buffer<PKPoint, std::__1::allocator<PKPoint>&>::__split_buffer(unsigned long, unsigned long, std::__1::allocator<PKPoint>&)

The CGPathRelease(path); line is necessary - without it I'm getting more memory leaks about CGPath which is understandable. When I'm using this implementation instead (for testing purposes):

CGFloat radius = MAX(self.frame.size.width, self.frame.size.height) * 0.5f; self.physicsBody = [SKPhysicsBody bodyWithCircleOfRadius:radius];

...everything is working well, without memory leaks. I wonder if this is Sprite Kit bug or I'm doing something wrong.

This maybe a difficult one for someone with limited Alfresco knowledge, so hopefully you'll understand it.

You'll need to create a repository webscript which takes as input a site and uses siteService methods to get the members and groups. You can peak at the siteMembers Share page which probably uses something similar to show the members and groups. And you'll probably will need to make it searchable :).
Change the current custom control which uses the default picker to select users/groups. Probably you'll only need to change the repository webscript url so it goes to the right new webscript. If you don't want to make any more changes, be sure to present the output in the exact same way.
You can start a workflow from you personal dashboard of from the my-workflow pages, so there is not always a site. And even if you're starting from a site big changes the site doesn't get passed to the start-workflow page. So you'll need to get the destination nodeRef (the node you're starting the workflow on) send it as param to your repository webscript and let it determine which site it is in.

First change the custom control which selects the assignee. This control goes to a repository webscript which shows/searches all the users/groups.

1797502 0 Is there a scala identity function?

If I have something like a List[Option[A]] and I want to convert this into a List[A], the standard way is to use flatMap:

scala> val l = List(Some("Hello"), None, Some("World")) l: List[Option[java.lang.String]] = List(Some(Hello), None, Some(World)) scala> l.flatMap( o => o) res0: List[java.lang.String] = List(Hello, World)

Now o => o is just an identity function. I would have thought there'd be some way to do:

l.flatMap(Identity) //return a List[String]

However, I can't get this to work as you can't generify an object. I tried a few things to no avail; has anyone got something like this to work?

Well you could use python itself to reverse the line through the filter command. Say the text you had written was:

Python

You could reverse it by issuing.

:1 ! python -c "print raw_input()[::-1]"

And your text will be replaced to become:

nohtyP

The "1" in the command tells vi to send line 1 to the python statement which we are executing: "print raw_input()[::-1]". So if you wanted some other line reversed, you would send that line number as argument. The python statement then reverses the line of input.

19262644 0 How to pass a NSMutableArray including NSManagedObjects to another view controller?

I embedded 'Core Data' into my app. I use a predicate and fetch the result. I use a mutableArray called "fetchedObjects" to get the (predicated and then fetched) result. Now I need to pass this result to another view controller. How can I do that?

1.First thing I tried is using 'NSCoding' but it didn't work out. I think Core Data doesn't comply with NSCoding, am I right?

If I can use 'NSCoding', how do I do it? I tried to save and then load the fetchedObjects but it didn't work out.

2.Off course I can define a pointer using

"product = [[Product alloc] initWithEntity:entity insertIntoManagedObjectContext:self.managedObjectContext];"

but how can I get just the "fetchedObjects" mutableArray but not all the objects?

3.Do you know a better way to pass a NSMutableArray having NSManagedObjects in it? and how can we pass the NSManagedObjects to the other view controllers, only in the context?

Thanks!

What I post is Begin with 'GO'. This site is build with WebForms, so there are these long __VIEWSTATE and __EVENTVALIDATION fields. We need send them as well.

Now we are ready to make the query. First we need to get a blank form. The following code are written in Python 3.3, through I think they should still work on 2.x.

import requests from lxml import etree URL = 'http://corp.sec.state.ma.us/CorpWeb/CorpSearch/CorpSearch.aspx' def get_fields(): res = requests.get(URL) if res.ok: page = etree.HTML(res.text) fields = page.xpath('//form[@id="Form1"]//input') return { e.attrib['name']: e.attrib.get('value', '') for e in fields }

With get_fields(), we fetched all <input>s from the form. Note there are also <select>s, I will just hardcode them.

def query(data): formdata = get_fields() formdata.update({ 'ctl00$MainContent$ddRecordsPerPage':'25', }) # Hardcode some <select> value formdata.update(data) res = requests.post(URL, formdata) if res.ok: page = etree.HTML(res.text) return page.xpath('//table[@id="MainContent_SearchControl_grdSearchResultsEntity"]//tr')

Now we have a generic query function, lets make a wrapper for specific ones.

def search_by_entity_name(entity_name, entity_search_type='B'): return query({ 'ctl00$MainContent$CorpSearch':'rdoByEntityName', 'ctl00$MainContent$txtEntityName': entity_name, 'ctl00$MainContent$ddBeginsWithEntityName': entity_search_type, })

This specific example site use a group of <radio> to determine which fields to be used, so 'ctl00$MainContent$CorpSearch':'rdoByEntityName' here is necessary. And you can make others like search_by_individual_name etc. by yourself.

Sometimes, website need more information to verify the query. By then you could add some custom headers like Origin, Referer, User-Agent to mimic a browser.

And if the website is using JavaScript to generate forms, you need more than requests. PhantomJS is a good tool to make browser scripts. If you want do this in Python, you can use PyQt with qtwebkit.

Update: It seems the website blocked our Python script to access it after yesterday. So we have to feign as a browser. As I mentioned above, we can add a custom header. Let's first add a User-Agent field to header see what happend.

res = requests.get(URL, headers={ 'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36', })

And now... res.ok returns True!

So we just need to add this header in both call res = requests.get(URL) in get_fields() and res = requests.post(URL, formdata) in query(). Just in case, add 'Referer':URL to the headers of the latter:

res = requests.post(URL, formdata, headers={ 'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36', 'Referer':URL, })

20061078 0 Finding cache cpi time

I need a formula or to at least be pointed in the right direction it involves cache and cpi time. I have a base machine that has a 2.4ghz clock rate it has L1 and L2 cache. L1 is 256k direct mapped write through . 90% read without a hit rate without penalty, miss penalty costs 4 cycles all writes take 1 cycle. L2 cache is 2mb, 4 way set associative write back. 99.5% hit rate 60 cycle miss penalty. 30% of all instructions are reads and 10% are writes all other instructions take one cycle.. I need to figure how to get the cpi. I know i have to find the base cpi but from there I'm not really sure where to go. Any tips on not just what the answer is but how is more important would be greatly appreciated.

38852460 0 Login page redirect new page if sucess

My application uses Mithril.js and Play Framework.

I would like to know if there is a (good) way to divide my application between mithril and play. I would like to have play renders a login.html, this login.html will only contain only the import of my mithril.js component (login.js). If the login is a success I would like play to redirect my application to another html page. This pages will contain all the imports of all my mithril's components.

So my application will have only two html pages on the play framework side, one which imports only one mithril component and the other which import all the others components (only if credentials are checked).

Play router :

GET / controllers.Index.index
Play controller :

def index = Action { Ok(views.html.login()) }

<!DOCTYPE html> <html lang="en"> <head> <title>IHM</title> StylesSheet import.. </head> <body id="app" class="body"> <script src="https://cdnjs.cloudflare.com/ajax/libs/mithril/0.2.2-rc.1/mithril.min.js"></script> <script src="@routes.Assets.versioned("javascripts/claravista/login.js")" type="text/javascript"></script> <script type="text/javascript"> m.route.mode = "pathname"; m.route(document.getElementById('app'), "/", { "/": login, }); </script> </body>

Mithril ask play check credentials (in component login)

m.request({method: "PUT", url: "/check-user", data : login.user }).then(returnCall);
Case Credentials false : ask again (I already did this part)

Case Credentials true : redirect to another html page (How to do this?)

<!DOCTYPE html> <html lang="en"> <head> <title>IHM</title> </head> <body id="appmain" class="body"> <script src="https://cdnjs.cloudflare.com/ajax/libs/mithril/0.2.2-rc.1/mithril.min.js"></script> ALL MY MITHRIL COMPONENTS IMPORT <script type="text/javascript"> m.route.mode = "pathname"; m.route(document.getElementById('appmain'), "/main", { "/main": main, }); </script>

How can I redirect to another html page after credentials are checked? Is there a better way to prevent the server to send all the JavaScript files before the user is logged?

40367483 1 Python determine whether an exception was thrown (regardless of whether it is caught or not)

I am writing tests for some legacy code that is littered with catch-all constructs like

try: do_something() do_something_else() for x in some_huge_list(): do_more_things() except Exception: pass

and I want to tell whether an exception was thrown inside the try block.

I want to avoid introducing changes into the codebase just to support a few tests and I don't want to make the except cases more specific for fear of unintentionally introducing regressions.

Is there a way of extracting information about exceptions that were raised and subsequently handled from the runtime? Or some function with a similar API to eval/exec/apply/call that either records information on every raised exception, lets the user supply an exception handler that gets run first, or lets the user register a callback that gets run on events like an exception being raised or caught.

If there isn't a way to detect whether an exception was thrown without getting under the (C)Python runtime in a really nasty way, what are some good strategies for testing code with catch-all exceptions inside the units you're testing?

You can somehow try to compress the information somehow. You need to show the user if he has read a post, only if the user logs on, so you should store the information somewhere near the user. The user might look throught your posts in a date sorted way, so read-post-information of nearly dates should ly nearby, for efficient caching and reading of many values.

Try a table with this stucture:

user_id
postmonth
readposts_array

Depending on how many posts you expect, you might use week or day instead of month. If you cache the value in your app, you might see a performance increase when displaying many posts.

I work for a publishing house and I can tell you from personal experience that a book cover can change quite frequently before going into print. Once it's available as physical product though (i.e. no more pre-order), it will remain the same until the next edition is published.

34707711 0 How do I get two things to hit each other and then remove one from the scene?

I have four colored bars aligned horizontally. I also have some of the exact colors falling from the top of the screen which need to be matched with the bars at the bottom and then removed from the scene on contact. (If falling yellow bar hits bottom yellow bar, remove falling yellow bar from the scene) So, should I have eight different cases for each node in an enum instead of four? This is what it looks like now:

enum Bodies: UInt32 { case blueBar = 1 case redBar = 2 case yellowBar = 4 case greenBar = 8 }

Some of them are not doing what they're supposed to which is why I'm asking. Thanks in advance.

Why, you can still static assert with const int:

#define static_assert(e) extern char (*ct_assert(void)) [sizeof(char[1 - 2*!(e)])] static_assert( THIS_LIMIT > OTHER_LIMIT )

Also, use boost!

BOOST_STATIC_ASSERT( THIS_LIMIT > OTHER_LIMIT )

... you'll get a lot nicer error messages...

Note the Statement documentation says:

By default, only one ResultSet object per Statement object can be open at the same time.

Now, you have these statements in your program:

ResultSet resultset = statement.executeQuery("select * from customer where first_name = '" + first_name + "'") ; statement.executeQuery("select * from customer where last_name = '" + last_name + "'") ; statement.executeQuery("select * from customer_order where amount = '" + amount + "'") ; statement.executeQuery("select * from customer_order where date_created = '" + date_created + "'") ; statement.executeQuery("select * from customer_order where reference_number = '" + reference_number + "'") ; statement.executeQuery("select * from customer_order where invoice_number = '" + invoice_number + "'") ; statement.executeQuery("select * from customer_order where status = '" + status + "'") ; statement.executeQuery("select * from ordered_product where quantity = '" + quantity + "'") ; statement.executeQuery("select * from ordered_product where product_name = '" + product_name + "'") ; statement.executeQuery("select * from ordered_product where product_price = '" + product_price + "'") ;

This means you are calling the executeQuery several times with the same Statement object. But you are only saving the result of the first execution into resultset.

That is, the ResultSet object that resultset refers to is the one from this statement:

statement.executeQuery("select * from customer where first_name = '" + first_name + "'") ;

All the others that follow it are separate queries and are not stored in the same variable if that's what you thought you were doing. They just create the ResultSet object, and then it gets thrown away because you don't assign the result to any variable.

As soon as you call the second executeQuery, because only one ResultSet object is allowed, the ResultSet object stored in resultset is closed, and a new one is opened. Then another, and then another.

Anyway, after you go through all these statements, you get to the part where you check resultset.next(). But at this point, that object, as I said, has already been closed.

Basically, you should decide which of the queries you want to run, run only that particular query, and then you'll have a live, open ResultSet in resultset. And then you can fill it in.

In addition, the part that prints the values from the result set should be inside the else block. You placed them after the curly brace of that else, which means you'll have trouble when no rows are returned from the query, because you'll be trying to print them anyway.

Looking at your code it appears there are 2 errors with your JSON. In it's original for it produces the follwoing string:

{"guid" : "26fac319-604b-11e5-b1fe", "senderid" : "003001", "campaign" : Weekday_EGV_21Sept_4pm_Round2_Tier1_Part1}}

You are missing quotes around that final field value of campaign and you have an extra } at the end. If you make the following change:

json_body = "{\"guid\" : \""+ guid+"\", \"senderid\" : \""+ senderid+"\", \"campaign\" : \""+ str(campaign)+"\"}"

it should resolve the JsonParseException error.

Right; let's see what we have here.

First, the code has to be blocked as follows:

variable declarations cursor declarations handler declarations everything else

So your DECLARE CURSOR c2 must appear between DECLARE CURSOR c1 and DECLARE CONTINUE HANDLER. Also, you only need one CONTINUE HANDLER because it takes effect from the point of declaration to the end of the procedure.

Next is the statement

INSERT INTO ip_ER_subtotal SELECT Starting_Pitcher, Game_Date, Game_Number, innings_pitched, 0.0 FROM starting_pitchers_game_log;

The named columns in the SELECT clause are the columns you're selecting from, not the ones you're inserting into, so they have to be columns in the table starting_pitchers_game_log. Also, since the columns not being copied from starting_pitchers_game_log (that is, ip_total, er_total and era) all have default values, you could use a column list on the INSERT statement, like so:

INSERT INTO pitcher_stats_temp (Starting_Pitcher, Game_Date, Game_Number, innings_pitched, er) SELECT pitcher_id, game_date, game_seq, innings_pitched, runs FROM starting_pitchers_game_log;

This saves typing, documents which columns you're actually inserting values into and insulates your INSERT statement from the physical order of columns in the source and target tables.

Next, once you finish the CURSOR c1 loop, don't truncate the table or you'll lose all the work you've just done! TRUNCATE TABLE deletes all rows currently in the table, and is used here to clear out the results of the previous run.

Finally, the two loops have to have different labels, say fetch_loop_1 and fetch_loop_2. You would also need to reset accum and end_of_cursor before entering the second loop. However, in this case I believe we can do everything in one loop with one cursor, which makes the code simpler and thus easier to maintain.

Here's the complete procedure:

DROP PROCEDURE IF EXISTS pitcher_stats_era; DELIMITER $$ CREATE PROCEDURE pitcher_stats_era() BEGIN DECLARE pit_id CHAR(10); DECLARE gdate DATE; DECLARE seq INT; DECLARE in_pit REAL; DECLARE er INT; DECLARE accum_ip REAL; DECLARE accum_er INT; DECLARE earned_run_avg REAL; DECLARE prev_year YEAR(4); DECLARE end_of_cursor BOOLEAN; DECLARE no_table CONDITION FOR SQLSTATE '42S02'; DECLARE c1 CURSOR FOR SELECT pitcher_id, game_date, game_seq, innings_pitched, earned_runs FROM pitcher_stats_temp ORDER BY pitcher_id, game_date, game_seq; DECLARE CONTINUE HANDLER FOR NOT FOUND SET end_of_cursor := TRUE; DECLARE EXIT HANDLER FOR no_table BEGIN SIGNAL no_table SET MESSAGE_TEXT = "Work table not initialized. Please call pitcher_stats_reset() before continuing", MYSQL_ERRNO = 1146; END; ------------------------------------------------------------------ -- The following steps are now performed by pitcher_stats_reset() ------------------------------------------------------------------ -- TRUNCATE TABLE ip_subtotal; -- Clear our work table for a new run -- Copy data from main table into work table -- INSERT INTO ip_subtotal -- (pitcher_id, game_date, game_seq, innings_pitched, earned_runs) -- SELECT pitcher_id, game_date, game_seq, -- IFNULL(innings_pitched, 0), -- replace NULL with 0, if -- IFNULL(runs, 0) -- column not initialized -- FROM starting_pitchers_game_log; --------------------------------------------------------------------- SET end_of_cursor := FALSE; -- reset SET prev_year := 0; -- reset control-break OPEN c1; fetch_loop: LOOP FETCH c1 INTO pit_id, gdate, seq, in_pit, er; IF end_of_cursor THEN LEAVE fetch_loop; END IF; -- check control-break conditions IF YEAR(gdate) != prev_year THEN SET accum_ip := 0.0; SET accum_er := 0; SET prev_year := YEAR(gdate); END IF; SET accum_ip := accum_ip + in_pit; SET accum_er := accum_er + er; IF accum_er = 0 THEN -- prevent divide-by-zero SET earned_run_avg := 0; ELSE SET earned_run_avg := (accum_ip / accum_er) * 9; END IF; UPDATE pitcher_stats_temp SET ip_total = accum_ip, er_total = accum_er, std_era = earned_run_avg WHERE pitcher_id = pit_id AND game_date = gdate AND game_seq = seq; END LOOP; CLOSE c1; END $$ DELIMITER ;

That should do the job. If anyone finds a bug, by all means please point it out.

EDIT: I've just added some code to illustrate how to protect against nulls coming from the source table, and how to avoid a divide-by-zero on the ERA calculation.

I am trying to put a string value in an array based on their position in relation to all of the elements with a class name. I get an array of the indexes that I want to use now I want to use each of the index values to select the appropriate value.

$(function () { $("#date").datepicker(); $('input[name=date]').datepicker(); var dateInput = $("select[name='searchString']"); var theClassTime = $("input.TextBoxDate"); var checkedindex = []; var classday = []; $("input[name='selectedCourses']").each(function (i) { if (this.checked) { // this works fine checkedindex.push(parseInt(i)); // this is where I’m trying to select values based on index. var dayofclass = $(".TextBoxDate:eq(" + checkedindex[i] + ")"); classday.push(dayofclass); alert(classday); } }); });

Say checkedindex has values: 2,3,9 meaning at index 0 of checkedindex is 2, at 1=3 and at 2=9. I want to use 2, 3 and 9 to do something like this:

var dayofclass = $(".TextBoxDate:eq(" + checkedindex[i] + ")");

What am I doing wrong here?

You are looping through the arrays. The puts function on its own just makes that difficult to see. Try this:

arrays = [[1, 52], [30, 1], [2, 1]] arrays.each do |array| puts array.inspect end

Output:

[1, 52] [30, 1] [2, 1]

TL;DR

No branch heads exist yet.

Detailed Explanation

A Git repository has no branches until you make your first commit. A newly-initialized repository sets HEAD to refs/heads/master, but refs/heads/master won't exist or contain a commit pointer until after the first commit is made.

During a commit, Git dereferences the symbolic-ref HEAD to find the head of the current branch, and then updates that head with the commit hash supplied by git-commit-tree.

The end result is that git branch has nothing to report in a new repository. With no branch heads present, it simply terminates silently with an exit status of zero.

Here is my code:

public class PlayMusicActivity extends Activity { WebView mWebView; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.playlist); mWebView = (WebView) findViewById(R.id.webView1); mWebView.setWebViewClient(new HelloWebViewClient()); mWebView.getSettings().setJavaScriptEnabled(true); mWebView.getSettings().setPluginsEnabled(true); mWebView.getSettings().setAllowFileAccess(true); mWebView.loadUrl("http://www.myweb.com/music.html"); } private class HelloWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) { mWebView.goBack(); return true; } return super.onKeyDown(keyCode, event); } @Override public void onPause() { mWebView.setVisibility(View.GONE); mWebView.destroy(); super.onPause(); } }

Appreciate for your help.

1945777 0 C++ Array vs vector

when using C++ vector, time spent is 718 milliseconds, while when I use Array, time is almost 0 milliseconds.

Why so much performance difference?

int _tmain(int argc, _TCHAR* argv[]) { const int size = 10000; clock_t start, end; start = clock(); vector<int> v(size*size); for(int i = 0; i < size; i++) { for(int j = 0; j < size; j++) { v[i*size+j] = 1; } } end = clock(); cout<< (end - start) <<" milliseconds."<<endl; // 718 milliseconds int f = 0; start = clock(); int arr[size*size]; for(int i = 0; i < size; i++) { for(int j = 0; j < size; j++) { arr[i*size+j] = 1; } } end = clock(); cout<< ( end - start) <<" milliseconds."<<endl; // 0 milliseconds return 0; }

use remove_if found under algorithm

Given a begin and end iterator along with a predicate, you can remove any element that results in the predicate evaluating to true. I'll include both C++03 and C++11 examples.

C++03:

#include <algorithm> #include <iostream> #include <iterator> #include <vector> #include <cstdlib> #include <ctime> template <typename T> struct is_equal { T val; is_equal (const T& v) : val (v) { } bool operator() (const T& test) { return (val == test); } }; struct is_odd { bool operator() (int test) { return (test % 2 == 1); } }; template <typename T> std::ostream& operator<< (std::ostream& os, const std::vector <T>& v) { typedef typename std::vector <T>::const_iterator itr; for (itr i = v.begin (); i != v.end (); ++i) os << *i << " "; return os; } int main (int argc, char* argv[]) { srand (time (NULL)); std::vector <int> vec (10); // vector has size of 10 std::generate (vec.begin (), vec.end (), rand); // populate with random numbers std::cout << vec << std::endl; vec.erase (std::remove_if (vec.begin (), vec.end (), is_odd ()), // removes all odd elements vec.end ()); std::cout << vec << std::endl; return 0; }

C++11:

#include <algorithm> #include <iostream> #include <iterator> #include <numeric> #include <vector> #include <cstdlib> template<typename T> std::ostream& operator<< (std::ostream& os, const std::vector <T>& v) { for (auto i : v) os << i << " "; return os; } int main(int argc, char* argv[]) { std::vector <int> vec(10); // vector has size of 10 std::iota (vec.begin(), vec.end(), 1); // populate with [1, 2, 3, ...] std::cout << vec << std::endl; vec.erase (std::remove_if (vec.begin(), vec.end(), [](int i){ return (i == 3); }), vec.end ()); std::cout << vec << std::endl; return 0; }

For any questions on using the STL, I personally consult http://en.cppreference.com/w/ and http://www.cplusplus.com/reference/

I've worked on a Drupal project with about 1 million nodes. We added transactional support and it wasn't too hard. You'll need to patch the core of course but this shouldn't be a major concern for an enterprise application with good support and documentation. I was working as the observing pair programmer on the transactional support. I think it took us about a day.

Edit:

I've been working as a Drupal Developer for a few years now. And recently, I have revised my position on Drupal in relation to best practices and enterprise application.

I don't think Drupal is particularly suited to the Enterprise space because:

Drupal's testing framework is too cumbersome (a domain specific language would be great)
There are too many contributed modules of poor quality
Drupal's content model resides partly in code and partly in the database schema
Drupal's developer community have become focused on sexy software rather than quality software
Drupal doesn't have mature developer tools (drush is changing that) or a development environment built in.
Drupal Development is browser and UI centric.
The centralized nature of Drupal.org/projects, CVS and Drupal's policy on Contrib Projects inhibits the evolution of individual software projects

Also: The enterprise Drupal Application I was once working on has now been ported into Rails.

Absolutely. For example, MySQL does not have hash and merge joins. Certain query patterns will suffer greatly there.

The notion that the RDBMS used does not matter is strange to me. Different databases have very non-uniform performance characteristics. Performance very much varies with workload.

If you want to exclude the RDBMS as much as possible from your tests you have to carefully make sure that you are not testing any RDBMS-specific performance features by accident. This is very hard.

I'm having problems inserting a particular line of code into my MySQL database. It inserts three rows just fine, but the "html_href" row isn't going in for whatever reason. Here is my code:

 function html_path() { $title = strtolower($_POST['title']); // convert title to lower case $filename = str_replace(" ", "-", $title); // replace spaces with dashes $html_href = $filename . ".html"; // add the extension }

And my MySQL query code:

 $query = "INSERT INTO work (title, logline, html_href, synopsis) VALUES"; $query .= "('".mysql_real_escape_string($_POST['title'])."',"; $query .= "'".mysql_real_escape_string($_POST['logline'])."',"; $query .= "'".html_path()."',"; $query .= "'".mysql_real_escape_string($_POST['synopsis'])."')"; $result = mysql_query($query);

The title, logline, and synopsis values go in just fine, but the html_href() function inserts a blank row.

I don't know much about Ocracoke, but why don't you look into Visual Studio?

6990135 0 What other hidden variables (pre-defined using macros) do I have access to in g++?

note: I am using g++ version 4.3.4

So I was learning about assert statements and came across a homebrew assert macro that uses that variables __LINE__ and __FILE__ which (cleverly) give the line number and the file name from where they were called -- in this case, from where the assertation failed. These are epic pieces of information to have!

I was able to infer that the variable __FUNCTION__ will give you the function name that you are inside of... amazing!! However, when assert.h is at work, you also get the arguments to the function (i.e. function: int main(int, char**) and all I can do currently is get the function name...

Generally speaking, where can I learn more about these wonderful hidden variables and get a complete list of all of them?

p.s. I guess I understand now why you aren't supposed to use variable names starting with __

My technique for this is to write a shell script that does the job, and then run it via find. For example, your actions could be written into a script munger.sh:

#!/bin/sh for file in "$@" do output="output_dir/$(basename "$file")" sed -e 's:foo:bar:g' "$file" > "$output" done

The find command becomes:

find input_dir -name "PATTERN" -exec sh munger.sh {} +

This runs the script with the file names as arguments, bundling conveniently large number of file names into a single invocation of the shell script. If you're not going to need it again, you can simply remove munger.sh when you're done.

Yes, you can do all sorts of contortions to execute the command the way you want (perhaps using find … -exec bash -c "the script to be executed" arg0 {} +) but it is often harder than writing a relatively simple script and using it and throwing it away. There tend to be fewer problems with quoting, for example, when you run an explicit script than when you try to write the script on the command line. If you find yourself fighting with single quotes, double quotes and backslashes (or back-quotes), then it is time to use a simple script as shown.

dups = {} newlist = [] for x in biglist: if x['link'] not in dups: newlist.append(x) dups[x['link']] = None print newlist

produces

[{'link': 'u2.com', 'title': 'U2 Band'}, {'link': 'abc.com', 'title': 'ABC Station'}]

Note that here I used a dictionary. This makes the test not in dups much more efficient than using a list.

5126721 0 Rails not reloading session on ajax post

I'm experiencing a very strange problem with Rails and ajax using jQuery (although I don't think it's specific to jQuery).

My Rails application uses the cookie session store, and I have a very simple login that sets the user id in the session. If the user_id isn't set in the session, it redirects to a login page. This works with no problems. JQuery GET requests work fine too. The problem is when I do a jQuery POST - the browser sends the session cookie ok (I confirmed this with Firebug and dumping request.cookies to the log) but the session is blank, i.e. session is {}.

I'm doing this in my application.js:

$(document).ajaxSend(function(e, xhr, options) { var token = $("meta[name='csrf-token']").attr('content'); xhr.setRequestHeader('X-CSRF-Token', token); });

and here is my sample post:

$.post('/test/1', { _method: 'delete' }, null, 'json');

which should get to this controller method (_method: delete):

def destroy respond_to do |format| format.json { render :json => { :destroyed => 'ok' }.to_json } end end

Looking at the log and using Firebug I can confirm that the correct cookie value is sent in the request header when the ajax post occurs, but it seems that at some point Rails loses this value and therefore loses the session, so it redirects to the login page and never gets to the method.

I've tried everything I can think of to debug this but I'm coming around to the idea that this might be a bug in Rails. I'm using Rails 3.0.4 and jQuery 1.5 if that helps. I find it very strange that regular (i.e. non-ajax) get and post requests work, and ajax get requests work with no problems, it's just the ajax posts that don't.

Any help in trying to fix this would be greatly appreciated!

Many thanks,
Dave

First of all, a service does not imply that a separate thread is running, but I guess this is what you want to do. If you run several threads, there is no way of the AndroidOS to terminate them besides killing the whole Dalvik VM. And this means that you have no way of knowing when you are about to be terminated. If you have a service with a thread and use proper life-cycle management, i.e. kill the thread when Android notifies the service that it is about to stop it, then it is easy to maintain state.

Regarding your question: use several services with one thread each

No a handler is a separate object class and so one would not need to be defined if you were making an Activity.

A handler would be used if you wanted to go do something in another thread/class and call back to the activity/ui.

You never check for 'eof' in your read loop in readInput(). This means you have garbage values (perhaps 0) for these lines after you hit eof:

 inputFile >> data[i].name; inputFile >> data[i].idNum; inputFile >> data[i].testNum;

Then what do you suppose is going to happen here, if data[i].testNum is zero?

 data[i].average = total / data[i].testNum;

You might consider checking inputFile.good() before each read from the stream, and handle it appropriately when it returns false.

Look at your RIFF header. This will tell you the endianness of the Wav file.

Use that endian-ness to read in your 32-bit floats correctly. For example: If your system is little endian (say, based on an x86 processor) and your wav file is big endian(say, created on an old PPC mac), you will need to do a 32-bit endian swap after you read in the data so that your float variable actually contains data that makes sense (this is usually a value between -1.0f and 1.0f )

The HTML5 spec has an interesting take on the issue of valid email addresses:

A valid e-mail address is a string that matches the ABNF production 1*( atext / "." ) "@" ldh-str 1*( "." ldh-str ) where atext is defined in RFC 5322 section 3.2.3, and ldh-str is defined in RFC 1034 section 3.5.

The nice thing about this, of course, is that you can then take a look at the open source browser's source code for validating it (look for the IsValidEmailAddress function). Of course it's in C, but not too hard to translate to JS.

Methods

You could use one of the following methods:

float:left; on .menu
display:inline-block; + vertical-align:top; on .menu
position:absolute; on #changetitle

With the float and vertical-align methods, you'll need to remove the margin-right on .menu ul (float will also work if you give the menu a width). With position:absolute you're goning to spend a whole lot of time getting the left and top values right :P

Which is best?

Probably inline-block. It's the easiest to set up, and just works. Best of all, it's dynamic. If you want to add another menu item at a later date and have to make the .menu div bigger, you don't have to change the CSS, whereas float usually would require you to set a width on .menu and position:absolute definitely requires that (as it is telling the browser exactly at what pixel to put #changetitle. If you're going to have more columns continue this design throughout the rest of the page, you may want to consider using column or display:table (never an actual <table> :P)

Long story short, use inline-block.

Here's a working demo: https://jsfiddle.net/mnfgo32g/12/

I developed a set of configurable utility functions for Riak mapreduce in Erlang. As I wanted to be able to specify sets of critera, I decided to allow the user to pass configuration in as a JSON document as this works well for all client types, although other text representations should also work. Examples of how these functions are used from curl are available in the README.markdown file.

You can pass an argument to each individual map or reduce phase function through the 'arg' parameter. Whatever you specify here will be passed on as the final parameter to the map or reduce phase, see the example below:

"query":[{"map":{"language":"erlang","module":"riak_mapreduce_utils", "function":"map_link","keep":false, "arg":"{\"bucket\":\"master\"}"}},

Your question raises some interesting issues. I will try to explain how you can fix it, but, as @Uri mentions, there may be better ways to address your problem.

I've assumed @tranfee is to be set equal to the first value in the hash whose key begins with "tran" and that @rate is to be set equal to the first value in the hash whose key begins with "rate". If that interpretation is not correct, please let me know.

Note that I've put initialize in the PaymentType module in a class (Papa) and made TranFee and Rate subclasses. That's the only way you can use super within initialize in the subclasses of that class.

Code

class Transaction attr_reader :tranfee, :rate def initialize(hash={}) o = PaymentType::TranFee.new(hash) @tranfee = o.instance_variable_get(o.instance_variables.first) o = PaymentType::Rate.new(hash) @rate = o.instance_variable_get(o.instance_variables.first) end end

module PaymentType class Papa def initialize(hash, prefix) key, value = hash.find { |key,value| key.start_with?(prefix) && value } (raise ArgumentError, "No key beginning with #{prefix}") unless key instance_variable_set("@#{key}", value) self.class.singleton_class.class_eval { attr_reader key } end end class TranFee < Papa def initialize(hash) super hash, "tran" end end class Rate < Papa def initialize(hash) super hash, "rate" end end end

I believe the method Object#singleton_class has been available since Ruby 1.9.3.

Example

reg_debit = {"name" => "reg_debit", "rate_base" => 0.0005, "tran_fee" => 0.21, "rate_basis_points" => 0.002, "tran_auth_fee" => 0.10} a = Transaction.new reg_debit p Transaction.instance_methods(false) #=> [:tranfee, :rate] p a.instance_variables #=> [:@tranfee, :@rate] p a.tranfee #=> 0.21 p a.rate #=> 0.0005

For others who are in the same requirement, you may consider my columnchooser implementation. My Dialog Form Declaration. (Dialog box which will be shown when columnchooser button is clicked.

All required fields will not be allowed to remove.

Creating the ColumnChooser Button for my Grid.

jq("#grid").jqGrid('navButtonAdd','#pager',{ caption: "Columns", title: "Customize Columns", onClickButton : function (){ /*jq("#grid").jqGrid('columnChooser',{ height:columnChooserHt });*/ createDialogDiv(); jq( "#dialog-form" ).dialog('open'); } });

Adding Save(OK) and Cancel Buttons to my Div.

jq(function(){ jq( "#dialog-form" ).dialog({ autoOpen: false, height: 300, width: 350, modal: true, buttons: { "OK": function() { changeColView(); jq( "#dialog-form" ).dialog('close'); }, Cancel: function() { jq( "#dialog-form" ).dialog('close'); } }, close: function() { } }); });

Function which inserts the column names with the select boxes which needed to be displayed on the ColumnChooser Dialog Box.

function createDialogDiv(){ var colModelDiv = jq("#grid").jqGrid('getGridParam','colModel'); var colNamesDiv = jq("#grid").jqGrid('getGridParam','colNames'); //alert(JSON.stringify(colModelDiv)); //alert(JSON.stringify(colNameDiv)); var container = document.getElementById('dialog-form'); //alert(colNamesDiv.length); var chckBox=""; for(i=0;i<colNamesDiv.length;i++){ if(colModelDiv[i].hidden && colModelDiv[i].hidden == true ){ chckBox+="<input type='checkbox' id='"+colNamesDiv[i]+"' name='"+colNamesDiv[i]+"' value='"+colModelDiv[i].name+"'>"+colNamesDiv[i]+"</input><br/>"; }else{ if(colModelDiv[i].editrules && colModelDiv[i].editrules.required){ chckBox+="<input type='checkbox' id='"+colNamesDiv[i]+"' name='"+colNamesDiv[i]+"' value='"+colModelDiv[i].name+"' disabled>"+colNamesDiv[i]+"</input><br/>"; } else chckBox+="<input type='checkbox' id='"+colNamesDiv[i]+"' name='"+colNamesDiv[i]+"' value='"+colModelDiv[i].name+"' checked>"+colNamesDiv[i]+"</input><br/>"; } } container.innerHTML=chckBox; }

Finally the actual method which changes the Columns chosen from Columnchooser.

function changeColView(){ var colModelDiv = jq("#grid").jqGrid('getGridParam','colModel'); var colNamesDiv = jq("#grid").jqGrid('getGridParam','colNames'); for(i=0;i<colNamesDiv.length;i++){ var chckBox=document.getElementById(colNamesDiv[i]); if(chckBox && chckBox.value && (!(chckBox.checked || chckBox.disabled))){ jq("#grid").jqGrid('hideCol',chckBox.value); } if(chckBox && chckBox.checked){ jq("#grid").jqGrid('showCol',chckBox.value); } } jq("#grid").trigger('reloadGrid'); }

Plz let me know your thoughts on this one.

23273433 0 javascript/jquery ignore or override :hover style

Short Description: I want to use JS/JQuery to take precedence over the CSS :hover psuedo-class for specific brief moments without removing the CSS rule for the other majority of cases. Since the site is already script-heavy enough I'm trying to find a solution that doesn't require me to nuke the CSS interaction and rely on mouseover/mouseout events. In my case there's a marked performance difference between the two.

Details: I've created a CSS-based dropdown shopping cart viewer. I rigged up some JQuery to force the cart open when the user triggers certain page interactions like adding an item to the cart. When the cart is "programmatically opened" an 8 second timer is used to close it. All that works. The Problem: I also want to add a click handler to the cart so that when the user clicks on it it will be explicitly closed whether the 8second timeout has expired or not. However, when they click on the cart they are - by definition - hovering over it, kicking in the :hover state and keeping it from closing. Is there a way to temporarily disable the :hover rule and then once the cart has closed reinstate it.

HTML:

<span class="minicart-wrapper"> <a class="minicart-anchor" href="...">Shopping Cart</a> <div id="minicart"> ... </div> </span>

CSS:

.minicart-wrapper #minicart { display: none; } .minicart-wrapper:hover #minicart, .minicart-wrapper #minicart.open { display: block; }

JQuery:

function openMinicart() { var minicart = jQuery('#minicart'); minicart.addClass('open'); minicart.bind('click', {}, closeMinicart); window.setTimeout(closeMinicart, 8000); } function closeMinicart() { var minicart = jQuery('#minicart'); minicart.removeClass('open'); minicart.unbind('click', closeMinicart); }

I've tried: a few suggestions I found here like changing .minicart-wrapper:hover #minicart to .minicart-wrapper:hover #minicart.canhover. I then added removeClass(canhover) to the beginning of closeMinicart() and setTimeout(function(){jQuery('#minicart').addClass('canhover')},500); to the end of it. However it seems that this is too short a timeout for the browser to refresh it's hover-state and before it's done rendering the hover re-triggers and the cart stays put.

Thanks for any suggestions.

Edit: Thanks Jedison. Here's the JSFiddle: http://jsfiddle.net/WJS3h/ . Also fixed some bugs in the sample.

Edit 2: Turns out I had a code error (oops) and the can-not-hover class method is the way to go. Thanks to everyone who commented.

The issue is that the images change the height of the div. You can keep them from doing that by floating them. Also, if you want them to always fit within the container, you'll need to adjust the width of the images. So, something like this might work:

#cool img { float:left; width:25%; height: auto; }

In the interest of creating semantic HTML, you may want to change your markup to something more like the following:

<nav> <ul> <li><a href="#"><img src="/my/cool/image.png" alt="Menu item 1"/></a></li> <li><a href="#"><img src="/my/cool/image.png" alt="Menu item 2"/></a></li> <li><a href="#"><img src="/my/cool/image.png" alt="Menu item 3"/></a></li> </ul> </nav>

37824729 1 How to use random.randint to find random 0 and 1 with not equal propbability

I am using DEAP toolbox in Python for Genetic Algorithm.

toolbox.register("attr_bool", random.randint, 0, 1) is a function randomly chooses 0 and 1 for populations in GA. I want to force GA to choose 0 and 1 randomly but with for example 80% one and the rest zero.

I think srng.binomial(X.shape, p=retain_prob) is a choice, but I want to use random.randint function. Wondering how we can do that?

If you simply want to squash all commits into a single, initial commit, just reset the repository and amend the first commit:

git reset hash-of-first-commit git add -A git commit --amend

Git reset will leave the working tree intact, so everything is still there. So just add the files using git add commands, and amend the first commit with these changes. Compared to rebase -i you'll lose the ability to merge the git comments though.

If you want to avoid forwarding landing page then use:

RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} !\.(gif|jpg|png|swf|css|html|js|ico|pdf)$ RewriteCond %{REQUEST_URI} !^/app\.php(/.*)?$ [NC] RewriteRule ^(.+)$ app.php/$1 [L]

.+ will match anything but not the landing page.

In case you want to exclude all the top level domain URLS then use:

RewriteCond %{HTTP_HOST} !^(www\.)?example\.com$ [NC] RewriteCond %{REQUEST_URI} !\.(gif|jpg|png|swf|css|html|js|ico|pdf)$ RewriteCond %{REQUEST_URI} !^/app\.php(/.*)?$ [NC] RewriteRule ^(.*)$ app.php/$1 [L]

This is what the ValidationGroup property is for. Suppose you have the following controls:

<asp:RequiredFieldValidator ID="rfv1" runat="server" ValidationGroup="Group1" /> <asp:RequiredFieldValidator ID="rfv2" runat="server" ValidationGroup="Group1" /> <asp:RequiredFieldValidator ID="rfv3" runat="server" ValidationGroup="Group2" /> <asp:Button ID="btn1" runat="server" ValidationGroup="Group1" Text="Button 1" /> <asp:Button ID="btn2" runat="server" ValidationGroup="Group2" Text="Button 2" />

In the example above, btn1 will only cause validation for the controls validated by rfv1 and rfv2, whilst btn2 will only cause validation for the control validated by rfv3.

I just found this jQuery plugin - http://markdalgleish.com/projects/tmpload/ Does exactly what you want, and can be coupled with $.tmpl

I have built a lightweight template manager that loads templates via Ajax, which allows you to separate the templates into more manageable modules. It also performs simple, in-memory caching to prevent unnecessary HTTP requests. (I have used jQuery.ajax here for brevity)

var TEMPLATES = {}; var Template = { load: function(url, fn) { if(!TEMPLATES.hasOwnProperty(url)) { $.ajax({ url: url, success: function(data) { TEMPLATES[url] = data; fn(data); } }); } else { fn(TEMPLATES[url]); } }, render: function(tmpl, context) { // Apply context to template string here // using library such as underscore.js or mustache.js } };

You would then use this code as follows, handling the template data via callback:

Template.load('/path/to/template/file', function(tmpl) { var output = Template.render(tmpl, { 'myVar': 'some value' }); });

Standard method would be to use numpy.linalg.eig.

from numpy import linalg as LA w, v = LA.eig(np.diag((1, 2, 3))) # w: # array([ 1., 2., 3.]) # v: # array([[ 1., 0., 0.], # [ 0., 1., 0.], # [ 0., 0., 1.]])

Obviously, if your matrix is very specific (let's say very large and sparse), usually you want to use iterative approach (e.g. Krylov subspace method) to find most dominant eigenvalues. See discussion for more details.

The first thing to point out is that there is nothing like racing condition. The right terminology is just race condition. Keep this in mind for the future ;-)

I suppose you are using a BroadcastReceiver to receive messages and that you have created the object and tell it to run in a separate thread because of the animation. This means that your showFab method can be called twice in one time. To handle this, define the method as synchronized.

There is no built-in NSString method available to do what you want. You need to write your own method. Objective-C does let you "extend" classes with new methods to cover cases like this.

This is how I would do it:

@interface NSString(Extend) -(NSInteger)proximity:(NSString*)otherString; @end @implementation NSString(Extend) -(NSInteger)proximity:(NSString*)otherString { NSUInteger length = [otherString length]; if(length != [self length]) return -1; NSUInteger k; NSUInteger differences = 0; for(k=0;k<length;++k) { unichar c1 = [self characterAtIndex:k]; unichar c2 = [otherString characterAtIndex:k]; if(c1!=c2) { ++differences; } } return differences; } @end

Represents a collection of associated String keys and String values that can be accessed either with the key or with the index.

So you can have only the data type string as value for an AppSettings key

And yes, AppSettings is the only place where you can store your settings.
MSDN defines AppSettings like this.

Contains custom application settings, such as file paths, XML Web service URLs, or any information that is stored in the.ini file for an application.

Regression Testing. Partly automated, partly manual, depending on the tools, time and money.

Normally you should different levels of testing, and even though as software developers we would like to automate everything, some things have to be verified by hand, by having a collection of test cases executed by testers.

The Wikipedia article on regression testing is a good read.

From the whole collection of tests that most be checked by hand, it is normally worthwhile to select the minimum set that guarantee the functionality of the system to reduce costs. The balance, of course, is a fine one and depends a lot on how much the code was actually changed. Good modularization of the software product helps a lot on having good regression testing.

Your string has backslashes which are read in Python as escape codes. These are when a character preceded by a backslash is changed into a special character. For example, \n is a newline. You will need to either escape them (with another backslash) or just use a raw string.

394146 0 Displaying polymorphic classes

I have an existing app with a command-line interface that I'm adding a GUI to. One situation that often comes up is that I have a list of objects that inherit from one class, and need to be displayed in a list, but each subclass has a slightly different way of being displayed.

Not wanting to have giant switch statements everywhere using reflection/RTTI to do the displaying, each class knows how to return its own summary string which then gets displayed in the list:

int position = 0; for (vector<DisplayableObject>::const_iterator iDisp = listToDisplay.begin(); iDisp != listToDisplay.end(); ++iDisp) cout << ++position << ". " << iDisp->GetSummary();

Similar functions are there to display different information in different contexts. This was all fine and good until we needed to add a GUI. A string is no longer sufficient - I need to create graphical controls.

I don't want to have to modify every single class to be able to display it in a GUI - especially since there is at least one more GUI platform we will want to move this to.

Is there some kind of technique I can use to separate this GUI code out of the data objects without resorting to RTTI and switch statements? It would be nice to be able to take out the GetSummary functions as well.

Ideally I'd be able to have a heierarchy of display classes that could take a data class and display it based on the runtime type instead of the compile time type:

shared_ptr<Displayer> displayer = new ConsoleDisplayer(); // or new GUIDisplayer() for (vector<DisplayableObject>::const_iterator iDisp = listToDisplay.begin(); iDisp != listToDisplay.end(); ++iDisp) displayer->Display(*iDisp);

AFAIK, there is no truthy? method in Ruby, so I couldn't find how to achieve this.

8132413 0 C# incrementing static variables upon instantiation

I have a bankAccount object I'd like to increment using the constructor. The objective is to have it increment with every new object the class instantiates.

Note: I've overriden the ToString() to display the accountType and accountNumber;

Here is my code:

public class SavingsAccount { private static int accountNumber = 1000; private bool active; private decimal balance; public SavingsAccount(bool active, decimal balance, string accountType) { accountNumber++; this.active = active; this.balance = balance; this.accountType = accountType; } }

Why is it that when I plug this in main like so:

class Program { static void Main(string[] args) { SavingsAccount potato = new SavingsAccount(true, 100.0m, "Savings"); SavingsAccount magician = new SavingsAccount(true, 200.0m, "Savings"); Console.WriteLine(potato.ToString()); Console.WriteLine(magician.ToString()); } }

The output I get does not increment it individually i.e.

savings 1001 savings 1002

but instead I get:

savings 1002 savings 1002

How do I make it to be the former and not the latter?

Does the compiler really let you assign object to Customer without a cast?

Anyway, DataContext won't be initialized yet in the constructor.

You could handle the DataContextChanged event, which will be raised whenever DataContext changes -- in this case, that'll probably just be when it's assigned in the course of instantiating the DataTemplate that creates MyUserControl. And that's just what you want.

XAML

<UserControl ... DataContextChanged="MyUserControl_DataContextChanged" ...

private Customer _customer; void MyUserControl_DataContextChanged(object sender, DependencyPropertyChangedEventArgs e) { _customer = (Customer)DataContext; }

Or you could just cast DataContext to Customer whenever you need to use it. Check for null, of course. You didn't say what you're doing with Customer so it's hard to be sure when you would need to do something with it.

array_reverse

Return an array with elements in reverse order

array array_reverse ( array $array [, bool $preserve_keys = false ] )

Takes an input array and returns a new array with the order of the elements reversed.

Mocking RDDS is difficult; executing your unit tests in a local Spark context is preferred, as recommended in the programming guide.

I know this may not technically be a unit test, but it is hopefully close enough.

Unit Testing

Spark is friendly to unit testing with any popular unit test framework. Simply create a SparkContext in your test with the master URL set to local, run your operations, and then call SparkContext.stop() to tear it down. Make sure you stop the context within a finally block or the test framework’s tearDown method, as Spark does not support two contexts running concurrently in the same program.

But if you are really interested and you still want to try mocking RDDs, I'll suggest that you read the ImplicitSuite test code.

The only reason they are pseudo-mocking the RDD is to test if implict works well with the compiler, but they don't actually need a real RDD.

def mockRDD[T]: org.apache.spark.rdd.RDD[T] = null

And it's not even a real mock. It just creates a null object of type RDD[T]

public class DrawTree extends JFrame{ public int XDIM, YDIM; public Graphics display; @Override public void paint(Graphics g) {} // override method // constructor sets window dimensions public DrawTree(int x, int y) { XDIM = x; YDIM = y; this.setBounds(0,0,XDIM,YDIM); this.setVisible(false); this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); display = this.getGraphics(); // draw static background as a black rectangle display.setColor(Color.black); display.fillRect(0,0,x,y); display.setColor(Color.red); try{Thread.sleep(500);} catch(Exception e) {} // Synch with system } // drawingwindow public static int depth(BinaryNode N) // find max depth of tree { if (N==null) return 0; int l = depth(N.left); int r = depth(N.right); if (l>r) return l+1; else return r+1; } // internal vars used by drawtree routines: private int bheight = 50; // branch height private int yoff = 30; // static y-offset // l is level, lb,rb are the bounds (position of left and right child) private void drawnode(BinaryNode N,int l, int lb, int rb) { if (N==null) return; try{Thread.sleep(100);} catch(Exception e) {} // slow down display.setColor(Color.green); display.fillOval(((lb+rb)/2)-10,yoff+(l*bheight),20,20); display.setColor(Color.red); display.drawString(N.element+"",((lb+rb)/2)-5,yoff+15+(l*bheight)); display.setColor(Color.blue); // draw branches if (N.left!=null) { display.drawLine((lb+rb)/2,yoff+10+(l*bheight),((3*lb+rb)/4),yoff+(l*bheight+bheight)); drawnode(N.left,l+1,lb,(lb+rb)/2); } if (N.right!=null) { display.drawLine((lb+rb)/2,yoff+10+(l*bheight),((3*rb+lb)/4),yoff+(l*bheight+bheight)); drawnode(N.right,l+1,(lb+rb)/2,rb); } } // drawnode public void drawtree(BinaryNode T) { if (T==null) return; int d = depth(T); bheight = (YDIM/d); display.setColor(Color.white); display.fillRect(0,0,XDIM,YDIM); // clear background drawnode(T,0,0,XDIM); }}

and another question

when i new a object from my tree class,i want to access that object in all my button codes so where i should define that or better to say , how i should define that object that can access in all my codes??

13144933 0 Form Authentication / Profiles slow on Azure Cloud, fine locally

I'm using MVC 4 on Azure, and it loads very slowly (over a minute). Here are the load times of a few pages: (the 6.9 minutes was when I tried loading 7 tabs with different pages)

This problem does not occur when I'm using the Azure emulator, locally.

I've tried using an extra large instance, and using remote desktop to run the site locally, and it was just as slow. Also I have tried using IIS Express and normal IIS, and nothing there either.

I created a completely fresh MVC project using the "Internet application" template, which includes security, and it is very slow as well, so I'm pretty sure the other things I'm using in my project are not causing the problem. Here are the load times with just the default MVC project: enter image description here

I was originally using separate affinity regions for my membership DB and my website, but I've tried using matching affinity groups on both the blank MVC template with forms authentication and my project.

Revisiting pages doesn't improve their speed significantly.

I also tried creating just a MVC site without authentication, with a 10x5000 table generated:

<html> <body> <table> <thead> <tr> @for (int i = 0; i < 10; i++) { <th>@i </th> } </tr> </thead> <tbody> @for(int i = 0; i < 5000; i++) { <tr> @for(int j = 0; j < 10; j++) { <td>Row @i , column @j</td> } </tr> } </tbody> </table> </body> </html>

This loads fine, both locally and on the cloud. Even from a cold start it is only ~10-15 seconds.

So I'm fairly certain that the issue lies in the Profile/Membership/Authentication of ASP.NET, but only while it is deployed to Azure (since I'm using the same SQL Azure database with Universal Providers when running locally, and there aren't these slowdowns).

I expected this problem to be more common, but the only thing that really seemed relevant was this: social.msdn.microsoft.com/Forums/en-US/windowsazuremanagement/thread/7d3323d8-571b-4b8f-9fdb-bd5ccc6c39b7 (possibly this: stackoverflow.com/questions/10791433/saving-changes-very-slow-via-datacontext)

I'm working through the things to try, as suggested in that thread, at: windowsazure.com/en-us/manage/windows/best-practices/

I'm using zendframework 2 , where I found it describing bcrypt configurations as follows:

$bcrypt = new Bcrypt(array( 'salt' => 'random value', 'cost' => 11 ));

what is the salt and what is the cost ? and how could them be used?

Here's a similar approach, using regular expressions instead:

import re def convert_string(s): return map(int, re.findall(r'[0-9]+', s))

Or using a list comprehension:

import re def convert_string(s): return [int(num) for num in re.findall(r'[0-9]+', s)]

This is a more general approach and will work for any character (in this case '|') that separates the numbers in the input string.

39184263 0 Catch image data via WI-FI

I have a device that takes pictures and send to an iPhone app via WI-FI. The iPhone has to connect to the device's WIFI, and when the device takes a picture it saves to camera roll of the iPhone if the app is in the foreground. However if the app is in the background, nothing happens.

My question is, can I catch this image data with another app that I create? I assume the data arrives to the iPhone via WI-FI when the app is in the background also.

Thank you for your help.

You share methods in a module, and you place such a module inside the lib folder.

Something like lib/fake_data.rb containing

module FakeData def random_address [Faker::Address.street_address, Faker::Address.city].join("\n") end module_function end

and inside your rake task just require the module, and call FakeData.random_address.

But, if it is like a seed you need to do every time you run your tests, you should consider adding this to your general before all.

E.g. my spec_helper looks like this:

# Requires supporting ruby files with custom matchers and macros, etc, # in spec/support/ and its subdirectories. Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f } RSpec.configure do |config| config.use_transactional_fixtures = true config.infer_base_class_for_anonymous_controllers = false config.order = "random" include SetupSupport config.before(:all) do load_db_seed end end

and the module SetupSupport is defined in spec/support/setup_support.rb and looks as follows:

module SetupSupport def load_db_seed load(File.join(Rails.root, 'db', 'seeds.rb')) end end

Not sure if you need to load the seeds, or are already doing this, but this is the ideal spot to also generate needed fake data.

Note that my setup support class is defined in spec/support because the code is only relevant to my specs, I have no rake task also needing the same code.

.aspx doesn't fulfill the MVC pattern because the aspx page (the 'view') is called before the code behind (the 'controller').

This means that the controller has a 'hard dependency' on the view, which is very much against MVC principles.

One of the core benefits of MVC is that it allows you to test your controller (which contains a lot of logic) without instantiating a real view. You simply can't do this in the .aspx world.

Testing the controller all by itself is much faster than having to instantiate an entire asp.net pipeline (application, request, response, view state, session state etc).

It's all explained in the documentation of JsonDataAccess. You'll have to do something like this:

// Create a data model with sorting keys for title GroupDataModel *model = new GroupDataModel(QStringList() << "title"); // Load the JSON data JsonDataAccess jda; QVariant list = jda.load("yourfile.json")["result"].toVariantList(); // Add the data to the model model->insertList(list.value<QVariantList>()); // Add your model to a ListView listView->setDataModel(model);

Okay so, I had a similar problem where I needed two buttons centered at the top of the page. Due to the problem I just dropped it to one button (it was easier that way). Since I'm having the same problem now with three buttons, I can't drop them to one, so I reverted back to the two original buttons that caused me a problem and came up with this...

<div class="row start-btns"> <div class="col-lg-6 col-lg-offset-3 test"> <div class="row"> <div class="col-lg-5 pull-left start-btn">Get Started</div> <div class="col-lg-5 pull-right tour-btn">Tour The Site</div> </div> </div> </div> <!-- End .row .start-btns --> @mixin btns { background: $yellow; color: $cream; font-weight: 700; font-size: 1.3em; text-transform: uppercase; text-align: center; padding: 12px 0px; } .call-btn, .start-btn, .tour-btn { @include btns; } .start-btn { margin-right: 1em; }

Having the parent ".test" span 6 cols and centered allowed me to nest another row with two buttons spanning 5 cols (actually 3 due to nesting) and pull one left and other right. This gives the effect that both buttons are spanning 3 columns and centered perfectly with a 10px spacing.

Nesting listviews is not support in Xamarin.Forms. You can try, but the inner one will not be scrollable and therefor useless.

If ListA has a list of ListB's, would it suite your needs to do grouping?

Essentially, you are grouping your lists of B within items of A (where in that image I showed your list A is a list of mobile devices and your lists of B are specific types within the generic OS).

To do this, when you create your listview and set your data template/source, you must now also set IsGroupingEnabled to true and GroupHeaderTemplate to the datatemplate created to show how it will be displayed visually (exactly the same as you normally would make a datatemplate with custom viewcells).

The only difference now is instead of your source being a list of A or a list of B, it is an list A (which extends ObservableCollection) which contains a list B.

You basically need to make your A viewmodel extend ObserableCollection so A is A but A is also a list/can be used as a list.

Now you just feed your list A (where each A has a list B) as the source of your ListView.

Without using a local variable, in most invocations we have effectively

if(field!=null) // true return field;

so there are two volatile reads, which is slower than one volatile read.

Actually JVM can merge the two volatile reads into one volatile read and still conform to JMM. But we expect JVM to perform a good faith volatile read every time it's told to, not to be a smartass and try to optimize away any volatile read. Consider this code

volatile boolean ready; do{}while(!ready); // busy wait

we expect JVM to really load the variable repeatedly.

28418617 0 copydb - How to create index in background?

I'm doing a lot of stuff with big databases in MongoDB and sometimes there's a need in making a copy of database where copydb command fits perfectly, however it does add global lock for whole mongod instance at the end of process for creating index.

I know that there's an argument to create index in background "background:true", but I didn't find such argument for copydb command (or copydatabase).

Is there way to avoid global lock and force background index creation for Copy Database?

Apparently this is how the company has worked for the past 10 years!

How do I convince management that what they are doing is actually costing them money/time/productivity? What kinds of active maintenance strategies exist? Which are good for small companies with scarce resources?

There is no issue with the first approach. I presume you are trying to iterate over few DataTimerPicker controls. If so, can you check the Name property of each DataTimerPicker control instances. I suppose it should be, datetimeBi1,datetimeBi2,datetimeBi3 ( just guessing after seeing your code).

Meantime, you can also check the immediate parent of your child controls ( DateTimePicker).

I would recommend posting to the Register method and based on the value of the selected option, redirect to the relevant view to complete the details. The users table could have a (say) IsRegistrationComplete field which is marked as true only when the 2nd form has been saved.

To do this in one view, you will need a view model with properties for the Register model, Owner model, ServiceCompany model and selected option.

View model

public class RegistrationVM { public RegisterVM Register { get; set; } public OwnerVM Owner { get; set; } public ServiceCompanyVM ServiceCompany { get; set; } [Required] public string CompanyType { get; set; } }

Controller

public ActionResult Register() { RegistrationVM model = new RegistrationVM(); model.Register = new RegisterVM(); return View(model); } public ActionResult Register(RegistrationVM model) { // Either Owner or ServiceCompany properties will be populated } public PartialViewResult CreateOwner() { var model = new RegistrationVM(); model.Owner = new OwnerVM(); return PartialView(model); } public PartialViewResult CreateServiceCompany() { var model = new RegistrationVM(); model.ServiceCompany = new ServiceCompany(); return PartialView(model); }

Notes: The partial views should not contain a <form> element (it will be inserted inside the <form> tag of the main view). The model in the partial views needs to be RegistrationVM so the controls are correctly prefixed and can be bound on post back (e.g. <input name="Owner.SomeProperty" ../> etc)

View

@model RegistrationVM @using(Html.BeginForm()) { <section> // render controls for the register model <section> <section> @Html.RadioButtonFor(m => m.CompanyType, "owner",new { id = "owner" }) <label for="owner">Owner</label> @Html.RadioButtonFor(m => m.CompanyType, "service",new { id = "service" }) <label for="service">Service Company</label> @Html.ValidationMessageFor(m => m.CompanyType) <button id="next" type="button">Next</button> <section> <section id="step2"></section> <input id="submit" type="submit" /> // style this as hidden }

Then add a script to handle the Next button which validates the existing controls, gets the value of the selected service, uses ajax to load the relevant form, re-parses the validator and displays the submit button

var form = $('form'); $('#next').click(function() { // Validate what been entered so far form.validate(); if (!form.valid()) { return; // correct errors before proceeding } // Get selected type and update DOM var type = $('input[name="CompanyType"]:checked').val(); if (type == "owner") { $('#step2').load('@Url.Action("CreateOwner")'); } else { $('#step2').load('@Url.Action("CreateServiceCompany")'); } // Re-parse validator so client side validation can be applied to the new controls form.data('validator', null); $.validator.unobtrusive.parse(form); // Show submit button $('#submit').show(); });

In your view code for the 'new' action use FormHelper tags that reference the same model as your create action eg.

<%= text_field :user, :login %>

Then in your create action, use a model instance with the same name:

@user = User.new # detect error, redirect to 'new'

The FormHelper will use the value of this instance if it is available.

The enctype should be on the <form> element

<form method="POST" enctype="multipart/form-data"> <input type="file" name="uploaded" style="margin-bottom: 10px"> </form>

PHP:

<?php echo $_FILES['uploaded']['type'] ?>

in your solution consider changing

<Trigger Property="MenuItem.Header" Value="enums:AnEnum.ItemA" >

<Trigger Property="MenuItem.Header" Value="{x:Static enums:AnEnum.ItemA}" >

in your example you check that header is equal to sting "enums:AnEnum.ItemA" not to enum AnEnum member ItemA.

11280343 0 How to plot family tree in R

I've been searching around how to plot a family tree but couldn't find something i could reproduce. I've been looking in Hadley's book about ggplot but the same thing.

I want to plot a family tree having as a source a dataframe similar to this:

dput(head(familyTree)) structure( list( id = 1:6, cnp = c("11", NA, "22", NA, NA, "33"), last_name = c("B", "B", "B", NA, NA, "M"), last_name_alyas = c(NA, NA, NA, NA, NA, "M"), middle_name = c("C", NA, NA, NA, NA, NA), first_name = c("Me", "P", "A", NA, NA, "S"), first_name_alyas = c(NA, NA, NA, NA, NA, "F"), maiden_name = c(NA, NA, "M", NA, NA, NA), id_father = c(2L, 4L, 6L, NA, NA, 8L), id_mother = c(3L, 5L, 7L, NA, NA, 9L), birth_date = c("1986-01-01", "1963-01-01", "1964-01-01", NA, NA, "1936-01-01"), birth_place = c("City", "Village", "Village", NA, NA, "Village"), death_date = c("0000-00-00", NA, NA, NA, NA, "2007-12-23"), death_reason = c(NA, NA, NA, NA, NA, "stroke"), nr_brothers = c(NA, 1L, NA, NA, NA, NA), brothers_names = c(NA, "M", NA, NA, NA, NA), nr_sisters = c(1L, NA, 1L, NA, NA, 2L), sisters_names = c("A", NA, "E", NA, NA, NA), school = c(NA, "", "", NA, NA, ""), occupation = c(NA, "", "", NA, NA, ""), diseases = c(NA_character_, NA_character_, NA_character_, NA_character_, NA_character_, NA_character_), comments = c(NA_character_, NA_character_, NA_character_, NA_character_, NA_character_, NA_character_) ), .Names = c("id", "cnp", "last_name", "last_name_alyas", "middle_name", "first_name", "first_name_alyas", "maiden_name", "id_father", "id_mother", "birth_date", "birth_place", "death_date", "death_reason", "nr_brothers", "brothers_names", "nr_sisters", "sisters_names", "school", "occupation", "diseases", "comments"), row.names = c(NA, 6L), class = "data.frame" )

Is there any way I can plot a family tree with ggplot? If not, how can i plot it using another package.

The primary key is 'id' and you connect to other members of the family using "id_father" and "id_mother".

Right answer would be declaring a common base class or interface but you said "I tried polymorphism, but". I do not know what (or how) did you try but assuming,

You are sure that all classes have a ToModel() method
It is not practical to declare a common interface or base class for your classes
You are using .NET 4.0 or above

You can do

var type = _projectService.GetTaskTypeById(id); dynamic task; switch (type) { case "MS": task = _projectService.GetMSTaskById(id); break; case "TL": task = _projectService.GetTLTaskById(id); break; case "ET": task = _projectService.GetETTaskById(id); break; default: throw new NotSupportedException("Unsupported Task Type: " + type); } task.ToModel();

Your code creates the Breakout object and sets its visibility:

Breakout bo = new Breakout(); bo.setVisible(true);

However, you never invoke any other methods. For example you may want to invoke a run method or a main method. You have to call those methods somehow in order to execute the code.

Another option would be to add a listener to the Breakout class so that it executes your code when the window opens, something like this:

addWindowListener(new java.awt.event.WindowAdapter() { public void windowOpened(java.awt.event.WindowEvent evt) { //call a method that runs the program here! } });

22859808 0 Cross and sub domain tracking with Google Analytics Universal Tag

This is my first question on Stackoverflow. So apologies if I make a mistake...

The challenge: I have a website (main.com), a sub-domain (sub.main.com) and 10 websites that send traffic, back and forth, to the main site and the sub domain. Let's call these sites site01.com, site02.com, site03.com,...,site10.com.

My question: How do I implement Universal Tag so I can do cross-domain tracking between main.com, sub.main.com and site01.com, site02.com, site03.com,...,site10.com.

I found instructions on how to do cross domain tracking for two sites. For example, on the main domain I will add the following code:

**<!-- Universal Analytics --> <script type="text/javascript"> (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('create', 'UA-XXXXXXXXX-X', 'main.com', {'allowLinker': true}); ga('require', 'linker'); ga('linker:autoLink', ['site01.com']); ga('send', 'pageview'); </script>**

And on site01.com, I will add the code below:

**<!-- Universal Analytics --> <script type="text/javascript"> (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) })(window,document,'script','//www.google-analytics.com/analytics.js','ga'); ga('create', 'UA-XXXXXXXX-X', 'site01.com',{'allowLinker': true}); ga('send', 'pageview'); </script>**

I don't know how to modify the code to include all 10 sites (site01.com, site02.com, site03.com,...,site10.com as part of the cross domain tracking.

Also, in relation to sub-domain tracking, I am guessing that the above code will also capture data from the sub-domain site (sub.main.com) with no issues.

Any help will be greatly appreciated.

But when retrieving the events for the predicate, events being on the startdate X (and later than the time of the start date) are never fetched. As soon as I set the startdate to 23:59 the previous day of X, all events of day X are fetched as expected.

Has anybody experienced this behaviour? Or is the documentation not correct and this is the expected behavoir?

Note: Tried on Iphone 6(iOS8) / Ipad mini 3(iOS8) / iPhone 5 (iOS 9)

EDIT: here is the documentiation of the method:

func predicateForEventsWithStartDate(_ startDate: NSDate, endDate endDate: NSDate, calendars calendars: [EKCalendar]?) -> NSPredicate

Creates and returns a predicate for finding events in the event store that fall within a given date range.

startDate
The start date of the range of events fetched.

endDate The end date of the range of events fetched.

calendars
The calendars to search, as an array of EKCalendar objects. Passing nil indicates to search all calendars.

11498591 0 Dis-allow installation on specific API Level

How to dis-allow my app to run on a specific API level? i know about the 3 specifiers in uses-sdk tag in the manifest. But that can't produce a logic i want to implement.

For eg: i want to allow my application to be installed on Level 4 to Level 10, dis-allow for Level 11 to Level 13 and again allow for Level 14 and Level 15.

Is that possible?

10684079 0 Outputting relevant input/output to a GUI, having received input in the console

I need to display some relevant information (like an introduction, yes/no questions and other questions) to a user via a gui, who then enters their response into the console. However, I cannot for the life of me think of or find a way to do this. How can I run the GUI but still allow input into the console? Here is some cut down code I have that shows what I'm trying to do. I'm doing this from a pps frame class that handles the container stuff. I just need to add buttons, text fields and later on action events.

public class gui extends XFrame { private JTextField[] textFieldsUneditable; public gui() { super(); textFieldsUneditable = new JTextField[10]; for(int i=0; i<textFieldsUneditable.length; i++) { textFieldsUneditable[i] = new JTextField(42); textFieldsUneditable[i].setEditable(false); add(textFieldsUneditable[i]); } revalidate(); repaint(); } public void paintComponent(Graphics g) { super.paintComponent(g); // code code code }

But what I have is other methods, of which I want to run and then output into these uneditable JTextFields using setText in the GUI after the user has responded in the console. I hope that makes sense!

You can't do that unless the subroutine is a built-in Perl operator, like sqrt for instance, when you could write

perl -e "print sqrt(2)"

or if it is provided by an installed module, say List::Util, like this

perl -MList::Util=shuffle -e "print shuffle 'A' .. 'Z'"

If it crashes because of byte alignment it is your fault.
boost uses #pragma pack for correctness
Compiling with a different byte alignment produce a complete different assemby code, so you have to compile all libraries with the same alignment.
If you have your boost project in visual the alignment is under Properties-> C/C+1-> Code Generation -> Struct Member Alignment. If you use another tool find how options are provided to the compiler and pass /Zp1(or -Zp1).

There will be multiple functions used by boost which would require a specific byte alignment. These function may be from the boost framework itself or from microsoft libraries. The classic case will be atomic operations (ie like InterlockedIncrement ) which requires a minimum byte alignment.

If there is a structure

struct { char c; int a; volatile int b; }

and b is used as atomic operand, The structure members alignment have to be guaranteed using #pragma pack. So boost use explicit #pragma pack for correctness.

Pretty much you want two different images of a star. One image is the plain white star and the other is the yellow (or whatever color) star that indicates it has been favorited. On the click event of the image, you just check which image is the src and then change it accordingly to match the necessary status of favorited or not. Then you run an ajax call to actually save the status to the database.

The closest tutorial I found so far: http://www.9lessons.info/2009/09/favourite-rating-with-jquery-and-ajax.html

14710042 0 IE img load returns error

I am trying to insert an image from an ajax repsonse. Everything work, but not in IE.

I have tried: Image load not working with IE 8 or lower, but get "broken image".

Tried to solve it described here: http://www.paulund.co.uk/handle-image-loading-errors-with-jquery, but it does not solve anything. I did not attach it to the document.ready function though, since this is ajax, the IE < 9 hack will never be triggered by the ajax call. the Ajax call is triggered by a mouse click which repsonds with an image link. When using JQuery's dialog function, IE does not show the image. Forcing it by right-clicking and 'Show image' shows the image.

Anybody know how to solve this problem?

32398155 0 PHP Sessions and Cookies set up

I want to learn something, that I couldn't find on the internet. I create a simple website, more like a simple web app, we the following structure.

index.php --> handles log In or Register home.php --> main state of website.

So basically I want when a user log in, the website will direct him to home.php. I did it already. But I get a really annoying bug. If I redirect bruteforce in www.someexample.com/home.php, the user can bypass the main log in screen. O.o
So I thought that if I can use a session checker to see if the user is log in or just a brute forcer -sorry about the bad term- the website will redirect him to log in screen. And if the user don't want every time to log in he can check a Remember me button to remember the session. So in the end I want to have two methods. one to check if a user is log in or not and the other to save his session even after if he close the computer until he poush the log out button.

I have checked many articles on the web but I couldn't find how to start in my own project. Can you guys help me start of with a basic structure. i use MySql.

12808179 0 Geocode results based on current location

In one of my activities i need to be able to do a geocoding (find a location by address String search). The problem is that my results are much too broad. When i search for "mcdonalds" i get results that are in different parts of the USA. How can i make it so a user can search for nearby restaurants (or any location) and the results will be within a certain distance? I basically need more precise results for my application.

4760995 0 Get change commands without modifying collection

Probably a very poorly named title, but anyway...

I am using the command pattern on a hierarchical data set. So basically I need a method that returns an object that describes the changes that will be made without actually changing the data. So for example:

Object 1 -> Object 2 -> Object 3

If I move object 1, it will cause a change in Object 2, which will cause a change in Object 3 because they depend on each other. So...I need a method to recursively go through the hierarchical collection and gather up the changes that are required to move Object 1 without actually modifying the collection. Halfway through the recursion it would be nice to be able to use something like Object1.Location, but it may already slated for change so I can't reliably use it.

I feel like there are plenty of algorithms and such that need to do this type of "in place" modification. As a non-CS major I didn't learn much of this type of thing, so I don't really even know what search terms to look for to find a "solution". I put solution in quotes because I realize there probably isn't a direct solution for my problem, but I am merely looking for some good guidelines/examples of this being done to get my brain cranking.

Can anyone provide some real-world examples of this type of thing being done? Thanks in advance.

16286775 0 A simple subtraction practice

I want to make a little game for my son to practice subtraction ( since he won't get off the computer !! ) . i have tried this code but my problem is that i want the first number to be always higher than the second number (cause that's wht they know so far ) ..this is my code :

<?PHP $string = "1234567890"; $shuffled = str_shuffle($string); $shuffled2 = str_shuffle($string); $num1 = substr($shuffled, 0, 3); $num2=substr($shuffled2, 0, 3); if ($num2 > $num1) { some code here .. } else { echo "$num1<BR>"; echo "$num2<BR>"; $res= $num1-$num2; echo "$res<BR>"; } ?>

so what is the missing code here ..i was thinking (goto) back from my days of basic to run code from the beginning until condition if satisfied ..but i don't know if that works in PHP .. Or ...is there a way to put a condition on shuffle in the first place so it can always return the first number higher than the second number?

I am not able to log the apache2 crashes in CoreDumpDirectory on ubuntu 10.10. I am using Django 1.2.3 and apache2 with mod_wsgi. I followed the steps listed in response to this question but to no avail. I added - CoreDumpDirectory /var/cache/apache2/
at the end of apache2.conf file and then after executing 'ulimit -c unlimited', restarted the apache server. Then I replicated the condition that causes apache error log to show- "child pid 27288 exit signal Segmentation fault (11)" but there is no mention of apache2 logging that crash in CoreDumpDirectory and also there is nothing in /var/cache/apache2.

EDIT:

I was able to solve this problem. The issue was with PyLucene environment being initialized on the run time. I was executing initvm() call everytime a request comes and it was causing segmentation fault. This link directed that I should do it in .wsgi file and after I did that there were no segmentation faults.

I don't think this will do you any good. AFAIK, there's no relationship between android.hardware.SensorEvent and com.sun.j3d.utils.behaviors.sensor.SensorEvent.

From a brief look at the Android source code, it looks like there's simply no way to create your own SensorEvent object. This is a serious oversight on Google's part, if you ask me.

Edit: Here's what I do. I write a method named sensorChanged(Sensor sensor, float[] values) to do all the work, and just call it from the regular onSensorChanged() method. Then, when I want to test sensor handling from within my app, I call sensorChanged() with whatever values I want. I might not be able to create a SensorEvent object, but this way I can still test my code.

First of all, inheritance in interfaces is OK, it applies in the same way as it does for class inheritance and is a very powerful tool.

Interfaces describe behavior, let's say an interface defines what a class "can do" so if you implement an interface you are declaring you can do what that interface specifies. For example:

interface ISubmergible { void Submerge(); }

So is obvious, if the class implements the interface then it can submerge. Some interfaces nonetheless imply other interfaces, for example, imagine this interface

interface IRunner { void Run(); }

That defines an interface that indicates that the class implementing it can run... nonetheless, in the context of our program is understood that, if something can run it can obviously walk, so you want to make sure that is fulfill:

interface IWalker { void Walk(); } interface IRunner : IWalker { void Run(); }

Finally, about the whole NotImplementedException thing... I'm amazed with some of the suggestions. A NotImplementedException should never, ever, be raised by an interface method of a class. If you implement an interface your are explicitly accepting the contract that interface establishes, if you raise a NotImplementedException you are basically saying "ok, I lied, I told you I supported the interface but I really don't".

Interfaces are meant to avoid having to worry about what the class implements and what doesn't. If you take that away they are useless. Much more important, your fellows will expect such behavior, even if you understand what you're doing the rest of your team won't and even you, 6 months from now won't understand the logic beneath it. So class2 violates common sense and interface purpose. Class2 does not implement the IBase so don't claim it does.

I mean I think I need some good examples as to why I should want to use it. Can someone provided me some codes as examples so I can understand it better? thax

private ByteArrayInputStream getPhoto() { Uri contactUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, id); Uri photoUri = Uri.withAppendedPath(contactUri, Contacts.Photo.CONTENT_DIRECTORY); Cursor cursor = getContentResolver().query(photoUri, new String[] {ContactsContract.CommonDataKinds.Photo.PHOTO}, null, null, null); if (cursor == null) { return null; } try { if (cursor.moveToFirst()) { byte[] data = cursor.getBlob(0); if (data != null) { return new ByteArrayInputStream(data); } } } finally { cursor.close(); } return null; }

This is my code. It is working.

26682699 0 Use case for not declaring a function as a prototype of another custom function?

I'm trying to get my head around the proper way of declaring js functions within my existing custom objects.

E.g. Usually I've done it this way to add functions to my existing object(s):

function whateverController() { this.doSomething = function() { } }

What is the advantage of doing it the following way?

function whateverController() { ...some random code } whateverController.prototype.doSomething = function() { }

From what I've been reading the latter example is the optimum way of declaring these functions to avoid having to recreate these functions every single a time I create a new whateverController object.

Could someone please provide a good use case though where my former example would be better suited? If at all? Any good reading links would be helpful too!

Is the latter method considered standard?

36655963 0 Recursive functions and removeEventListener

I want to write a dynamic button creator. So I have the html file

<body> <button id="0" type="button" onclick="create_button(0)">Create button 1</button> </body>

and js file which "simulates" proper action

var counter = 0; function create_button(n) { /*Shift up*/ for (i=counter; i>n; i--) { document.getElementById(i).id = i+1; document.getElementById(i+1).innerHTML = i+1; }; /*Create new button*/ var new_button = document.createElement("Button"); new_button.innerHTML = n+1; new_button.type = "button"; new_button.id = n+1; function helper() { create_button(n+1); }; new_button.addEventListener('click', helper ); document.body.insertBefore(new_button,document.getElementById(n).nextSibling); counter++; };

However /*Shift up*/ part only changes id and innerHTML of buttons not the action of click. So in order to fix that I need to add in /*Shift up*/ two lines which should work as

document.getElementById(i+1).addEventListener('click', helper(i+1) ); document.getElementById(i+1).removeEventListener('click', helper(i) );

Clearly It will not work. Due to recursive nature of create_button function, I imagine that helper should be moved outside of create_button. But I have no idea how to do it.

Some additional info I simplified the code, but in practice buttons have some addition functions which depend on n. Let say that we also want to alert the position of the button. So we change helper to

function helper() { create_button(n+1); alert(n+1); };

See in https://jsfiddle.net/o3Lsttyq/3/ what alerts say. Click for example 1,1,3.

11025128 0 pl/sql Compare with previous row

The goal is to combine Time_a within 10 min interval that has same ID. And group the ID.

ID Time_a -> ID ------------ ---------- 1 12:10:00 1 1 12:15:00 2 1 12:20:00 2 2 12:25:00 2 12:35:00 2 02:00:00

It became two '2' because time interval between row5 and row6 is more than 10 min. I was able to combine within 10-min difference, but it doesn't distinguish ID.

select ID from( select id, Time_a, min(time) OVER (order by id, time rows between 1 preceding and 1 preceding) prev_t_stamp from dual ) where abs(Time_a-prev_t_stamp)>10/1440

For the benefit of those of you who land up here in search of a working implementation. The following code works for every search criteria no matter how complex. I am using Codeigniter, just for the record.

 if($this->input->get('_search')=="true"){ $where = ""; $ops = array( 'eq'=>'=', 'ne'=>'<>', 'lt'=>'<', 'le'=>'<=', 'gt'=>'>', 'ge'=>'>=', 'bw'=>'LIKE', 'bn'=>'NOT LIKE', 'in'=>'LIKE', 'ni'=>'NOT LIKE', 'ew'=>'LIKE', 'en'=>'NOT LIKE', 'cn'=>'LIKE', 'nc'=>'NOT LIKE' ); $filters = json_decode($this->input->get('filters'), true); $first = true; foreach ( $filters['rules'] as $item){ $where .= $first ? " WHERE" : " AND "; $searchString = $item['data']; if($item['op'] == 'eq' ) $searchString = "'".$searchString."'"; if($item['op'] == 'bw' || $item['op'] == 'bn') $searchString = "'".$searchString."%'"; if($item['op'] == 'ew' || $item['op'] == 'en' ) $searchString = "'%".$searchString."'"; if($item['op'] == 'cn' || $item['op'] == 'nc' || $item['op'] == 'in' || $item['op'] == 'ni') $searchString = "'%".$searchString."%'"; $where .= " ".$item['field']." ".$ops[$item['op']]." ".$searchString; if ($first) { $first = false; } } $sql = "SELECT * FROM applicant".$where; $query = $this->db->query($sql); $result = $query->result_array(); $i=0; foreach ($result as $myrow){ $responce->rows[$i]['id']=$myrow['id']; $responce->rows[$i]['cell']=array($myrow['id'],$myrow['contingent_id'],$myrow['firstname'],$myrow['lastname'],$myrow['age'],$myrow['grouptype_id'],$myrow['registrationtype_id']); $i++; } }

You can use .one() for that.

$("a").one("click", function() { // do your stuff }

Or you could store the fact that the link has already been clicked by adding a .data() attribute.

$('a').click(function() { var a = $(this); if (a.data('clicked') == 'clicked') return false; // do your stuff a.data('clicked', 'clicked'); });

Whatever you do you should really drop that inline js (for maintainability and clean code).

5869224 0 Serialize large files - store in memory or on disk?

I do a networking app using iPhones and their limited memory is something I must consider. My Message class holds both a image and a video. Now I am about to implement the video file transfer (image already implemented, and is working). I guess the image can be loaded to memory because of their relatively small size (1+ MB), but large video files must reside on disk to avoid filling the memory.

To be able to encode the Message instance for sending it over the network (using NSCoding protocol), I convert the UIImage instance to NSData that resides in memory:

 NSData *imageData = UIImagePNGRepresentation(self.image);

The video is stored on disk and is accessed by using an NSURL videoURL. The content of this url (the video file itself) should also be encoded, and it have to be converted to NSData as well. If I init an NSData instance with this url, the videoData will be loaded into and occupying all available space in memory...

NSData *videoData = [[NSData alloc] initWithContentsOfURL:videoURL];

...(am I wrong?) so this must be accomplished using another technique.

Should I send the Message instance (without the video) first, and then send the video separately using some unknown technique? Or maybe I did miss some conceptual steps here?

I cant really be specific about your template structure (template-part content-title??) but using a generic example the following will display the featured image where available;

your content template page (content.php, template-page, etc..)

 // WP_Query arguments $args = array ( 'nopaging' => false, 'posts_per_page' => '2', 'offset' => '1', ); // The Query $the_query = new WP_Query( $args ); // The Loop if ( $the_query->have_posts() ) { while ( $the_query->have_posts() ) { $the_query->the_post(); ?> <article> <?php if ( has_post_thumbnail() ) : ?> <div class="post-thumbnail"> <a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"> <?php the_post_thumbnail(); ?> </a> </div> <?php endif; ?> <div class="post-title"> <?php echo '<h2>' . get_the_title() .

There is a major flaw in your design. The error is obvious. In this line

final helpers helpers = new helpers();

you are trying to create an object of an activity which is a very very bad practice. You cannot simply create an object of an activity like this. All Activities in Android must go through the Activity lifecycle so that they have a valid context attached to them. In this case a valid context is not attached to the helper instance. So as a result the line

SharedPreferences sharedPref = this.getPreferences(Context.MODE_PRIVATE);

causes a null pointer as 'this' is null. (Why? Because this refers to the context which has not yet been created as the activity is not started using startActivity(intent))

Another thing though this is not an error, you must use activity names starting with an upper case letter. It is the convention followed and will make your code more readable. Your code is pretty confusing due to the weird use of upper and lower case names. You declare your class with a lower case letter while at some places the variables are upper case. which causes confusion. The rule is that classes, interfaces, etc should start with upper case letters and variables as lower case.

So in this case what do you do?

You never start your Helper activity and I think you do not need to show it to the user. That is it needs to do some work without user interaction. You should make it a service. And then start it using startService(intent).Or you may also create it as a Java class, depends on your use case.

Edit: By the way I answered another similar question having the same problem but involving services later today.

A simple approach to error-checking user input is with a while loop. For example:

def make_score(): while True: score = raw_input('Air, Water, or Grass? ') if score in Attack: break else: print 'Invalid selection.' return score

This will loop to input until the user enters a string that matches one of your list items (in the Attack list).

As I was writing the question, I figured out the answer, so I decided to post it right here. But if someone has a different solution, that is more stable or clean, I'm still interested.

The dictionary to be passed to .format should be:

vars(sys.modules[func.__module__])

There's one more issue you might need to address if you are using the Windows 2008 Server with IIS7. The server might report the following error:

Microsoft Office Excel cannot access the file 'c:\temp\test.xls'. There are several possible reasons:

The file name or path does not exist.
The file is being used by another program.
The workbook you are trying to save has the same name as a currently open workbook.

The solution is posted here (look for the text posted by user Ogawa): http://social.msdn.microsoft.com/Forums/en-US/innovateonoffice/thread/b81a3c4e-62db-488b-af06-44421818ef91?prof=required

10736964 0 gitolite-admin clone issue

I am going nuts with a problem cloning the gitolite-admin repository. I have followed this http://sitaramc.github.com/gitolite/install.html#migr and it went perfectly.

I ran ssh-keygen -t rsa and scp ~/.ssh/id_rsa.pub morten@ubuntu-server:/tmp/morten.pub

authorized_keys on the server looks like this:

# gitolite start command="/home/morten/gitolite/src/gitolite-shell morten",no-port-forwarding,no-X11-forwarding,no-agent-forward$ # gitolite end

Which AFAIK is okay.

When I run git clone morten@ubuntu-server:gitolite-admin on my client, I get

fatal: 'gitolite-admin' does not appear to be a git repository fatal: The remote end hung up unexpectedly

I have no idea what I missed!

When you invoke the printloop function with 5 the for loop essentially becomes

for (x = 5; x < 5; x++) { //... }

And x < 5 will never be true.

I guess what you meant was something like

for (x = 0; x < valx; x++) { //... }

You don't need EXECUTE IMMEDIATE in this context.

DECLARE long_var long:=0; BEGIN DBMS_OUTPUT.PUT_LINE(LENGTH(long_var)); SELECT filesize INTO long_var FROM files; DBMS_OUTPUT.PUT_LINE(LENGTH(long_var)); END; /

EXECUTE IMMEDIATE runs a stand alone statement of SQL from your PL/SQL code. It can't return anything to your code. The statement you're using isn't valid SQL so you get the ORA-00905. It is valid PL/SQL code and so works as you'd expect once EXECUTE IMMEDIATE is removed.

Edit

Code for your follow on question: To do this with more than one row you can use this

DECLARE CURSOR C1 IS SELECT filesize FROM files; BEGIN FOR files IN c1 LOOP DBMS_OUTPUT.PUT_LINE(LENGTH(files.filesize)); END LOOP; END; /

40606285 0 C# FtpWebRequest creates corrupted files

I'm using .NET 3.5 and I need to transfer by FTP some files. I don't want to use files because I manage all by using MemoryStream and bytes arrays.

Reading these articles (article and article), I made my client.

public void Upload(byte[] fileBytes, string remoteFile) { try { string uri = string.Format("{0}:{1}/{2}", Hostname, Port, remoteFile); FtpWebRequest ftp = (FtpWebRequest)WebRequest.Create(uri); ftp.Credentials = new NetworkCredential(Username.Normalize(), Password.Normalize()); ftp.UseBinary = true; ftp.UsePassive = true; ftp.Method = WebRequestMethods.Ftp.UploadFile; using (Stream localFileStream = new MemoryStream(fileBytes)) { using (Stream ftpStream = ftp.GetRequestStream()) { int bufferSize = (int)Math.Min(localFileStream.Length, 2048); byte[] buffer = new byte[bufferSize]; int bytesSent = -1; while (bytesSent != 0) { bytesSent = localFileStream.Read(buffer, 0, bufferSize); ftpStream.Write(buffer, 0, bufferSize); } } } } catch (Exception ex) { LogHelper.WriteLog(logs, "Errore Upload", ex); throw; } }

The FTP client connects, writes and close correctly without any error. But the written files are corrupted, such as PDF cannot be opened and for DOC/DOCX Word shows a message about file corruption and tries to restore them.

If I write to a file the same bytes passed to the Upload method, I get a correct file. So the problem must be with FTP transfer.

byte[] fileBytes = memoryStream.ToArray(); File.WriteAllBytes(@"C:\test.pdf", fileBytes); // --> File OK! ftpClient.Upload(fileBytes, remoteFile); // --> File CORRUPTED on FTP folder!

trying to create a quiz using div elements from different file containing select option tags. Need to create a function which will load all the "appropriate div tags" according to the selected option and display the dropdown options again after each option has been selected.

I hope this makes sense, I'm not too familiar with jquery and any help would be highly appreciated.

Any other techniques which would be better suited are also welcomed. thanks.

Try a simple trick. Apple has got samples on its site to show how to zoom into a photo using code. Once done zooming, using graphic context take the frame size of the bounding view, and take the image with that. Eg Uiview contains scroll view which has the zoomed image. So the scrollview zooms and so does your image, now take the frame size of your bounding UIview, and create an image context out of it and then save that as a new image. Tell me if that makes sense.

Cheers :)

I think it simply posts the form to user_agreement4.php and does nothing else) When JavaScript is disabled and I click on the YES radio button and submit it, the message “YES status checked” displays correctly. Please note that the code below is for user_agreement4.php. The form will be submitted to itself.

What am I doing wrong?

Please note that this is unfinished code-I haven't added things like cookies, redirection etc. yet.

Also I have a question about choosing answers. May I choose more than one reply as an answer?

<?php // Set variables $selected_radio = 'test'; session_start(); // start up your PHP session! // The below code ensures that $dest should always have a value. if(isset($_SESSION['dest'])){ $dest = $_SESSION['dest']; } // Get the user's ultimate destination if(isset($_GET['dest'])){ $_SESSION['dest'] = $_GET['dest']; // original code was $dest = $_GET['dest']; $dest = $_SESSION['dest']; // new code } else { echo "Nothing to see here Gringo."; //Notification that $dest was not set at this time (although it may retain it's previous set value) } // Show the terms and conditions page //check for cookie if(isset($_COOKIE['lastVisit'])){ /* Add redirect >>>> header("Location: http://www.mywebsite.com/".$dest); <<This comment code will redirect page */ echo "aloha amigo the cookie is seto!"; } else { echo "No cookies for you"; } //Checks to see if the form was sent if (isset($_POST['submitit'])) { //Checks that a radio button has been selected if (isset($_POST['myradiobutton'])) { $selected_radio = $_POST['myradiobutton']; //If No has been selected the user is redirected to the front page.

20307980 0 PHP if/else not working as intended

Below is some code I am using to check if a field says "CIT" to display that as the selected item in the html select box. Elseif the field says "CSE", display "CSE" as selected and CIT/CSE in the drop downs respectively if one or the other is selected in the database. No matter what is in the database field the code always seems to use the first if statement. So courses with "CSE" as course_major are showing "CIT" as the first option in the drop down, however it shouldn't be this way.

while ($row = mysqli_fetch_array ($r, MYSQLI_ASSOC)) { $bg = ($bg=='#B39C56' ? '#000000' : '#0A0A0A'); echo '<tr> <form action="edit_course.php" method="post"> <!--Next Course First Line of Table --><td>Major:</td> <td style="text-align:left">'; if ($row['course_major'] = "CIT") { echo' <select name="course_major" class="rounded"> <option value="'.$row['course_major'].'">'.$row['course_major'].'</option> <option value="CSE">CSE</option> </select>'; } elseif ($row['course_major'] = "CSE") { echo' <select name="course_major" class="rounded"> <option value="'.$row['course_major'].'">'.$row['course_major'].'</option> <option value="CIT">CIT</option> </select>'; }; echo'</td> ........................

8645865 0 3D World with GPS data in Javascript and html5

I would like to create a 3D rotating world in javascript, dynamically positioning points from a json to display data such as text or pictures, and randomly rotating from a point to another.

I would like to receive examples and suggestions before beginning to develop. Which libraries would you use? Which algorythm would you use to rotate the world accordingly to the gps data?

Edit: Reading again my question I think I should make it more clear. I want to make something like Google Earth, without the zoom. There will be points on a 3d model of the earth, and a rotation from a point to another.

31790460 0 Haproxy - How to parse and store parts of an incoming URL

If I have an incoming url like so:

foo.com/FooID/1234/FooLocation/NYC

How do I go about extracting these values from the incoming request so I can use them for a lookup in a map file. I know this must be doable with regex, but I was hoping for a more elegant solution similar to extracting url parameters:

Example:

http-request set-header X-FooId %[url_param(FooID)].

If not, which regex function would be best used in this instance so I could either store this value or access it directly via a header?

I don't know a very short way, but I would use something like this (as qick hack to get an impression):

 try { // this is a new frame, where the picture should be shown final JFrame showPictureFrame = new JFrame("Title"); // we will put the picture into this label JLabel pictureLabel = new JLabel(); /* The following will read the image */ // you should get your picture-path in another way. e.g. with a JFileChooser String path = "C:\\Users\\Public\\Pictures\\Sample Pictures\\Koala.jpg"; URL url = new File(path).toURI().toURL(); BufferedImage img = ImageIO.read(url); /* until here */ // add the image as ImageIcon to the label pictureLabel.setIcon(new ImageIcon(img)); // add the label to the frame showPictureFrame.add(pictureLabel); // pack everything (does many stuff. e.g. resizes the frame to fit the image) showPictureFrame.pack(); //this is how you should open a new Frame or Dialog, but only using showPictureFrame.setVisible(true); would also work. java.awt.EventQueue.invokeLater(new Runnable() { public void run() { showPictureFrame.setVisible(true); } }); } catch (IOException ex) { System.err.println("Some IOException accured (did you set the right path?): "); System.err.println(ex.getMessage()); }

17701718 0 Combining solve and dsolve to solve equation systems with differential and algebraic equations

I am trying to solve equation systems, which contain algebraic as well as differential equations. To do this symbolically I need to combine dsolve and solve (do I?).

Consider the following example: We have three base equations

a == b + c; % algebraic equation diff(b,1) == 1/C1*y(t); % differential equation 1 diff(c,1) == 1/C2*y(t); % differential equation 2

Solving both differential equations, eliminating int(y,0..t) and then solving for c=f(C1,C2,a) yields

C1*b == C2*c or C1*(a-c) == C2*c c = C1/(C1+C2) * a

How can I convince Matlab to give me that result? Here is what I tried:

syms a b c y C1 C2; Eq1 = a == b + c; % algebraic equation dEq1 = 'Db == 1/C1*y(t)'; % differential equation 1 dEq2 = 'Dc == 1/C2*y(t)'; % differential equation 2 [sol_dEq1, sol_dEq2]=dsolve(dEq1,dEq2,'b(0)==0','c(0)==0'); % this works, but no inclusion of algebraic equation %[sol_dEq1, sol_dEq2]=dsolve(dEq1,dEq2,Eq1,'c'); % does not work %solve(Eq1,dEq1,dEq2,'c') % does not work %solve(Eq1,sol_dEq_C1,sol_dEq_C2,'c') % does not work

No combination of solve and/or dsolve with the equations or their solutions I tried gives me a useful result. Any ideas?

6279882 0 Tutorials for Writing Common Code for use on Windows, OS X, iOS, and potentially Android

I'm looking at writing an application that I would like to use on Windows, OSX, and iOS (maybe pushing into Android if other people want to use it). I want to duplicate as little work as possible and I'm having a hard time finding information on the best way to do this.

From what I've found so far I can't use a framework like QT because iOS doesn't support QT so it looks like I'm stuck recreating the interface for each target. I'm looking at writing the business logic in C++ because it seems to be supported by the native tools (Visual Studio and xCode).

Has anyone had experience with a setup like this and if so can you point me towards a good reference for this kind of development?

What you're describing sounds like the proper behavior for a "p" tag. See here. If you don't want the link below it why don't you use a "div" instead of a "p" tag? You should be able to transfer all styles over to the new div.

Update: I think the HTML below would do what you are saying. I did the styles inline for simplicity, you'll want to move those to your css file.

<div class="footer"> <div style="float:left">bla bla bla bla</div> <a href="url_here" style="float:right" class="next" title="Next">Next</a> </div>

Well, you can check if a variable is an array or string using instanceOf or typeOf or .constuctor: See here http://tobyho.com/2011/01/28/checking-types-in-javascript/

 if(myVariable instanceOf Array){ //multi select } else if(myVariable.constructor === String){ //single select }

or you can simply convert your string to an array and check the length of the array.

 $scope.myVariable = $scope.myPreviousVar.split(','); // or however you want to delimit this if($scope.myVariable.length === 1){ //single select } else if($scope.myVariable.length > 1){ //multi select }

Yes, you will need a 64 bit JVM to utilize all your memory. I am not up to date with what you can get for Windows so I will let someone else answer that.

However, I think the main reason why you can't find a 64 bit netbeans is that it is 100% pure java and architecture independent. Eclipse provides an alternative GUI framework with a more native look and feel (SWT) and uses it for the development environment itself. Once you link to your java app to native libraries you need to distribute the libraries for the correct architecture, hence the architecture dependence of the eclipse distribution (your second item).

You have this problem because you're not correctly using pointers. Look, you create two TreeNode's on a stack, then you take their addresses, and make them children of new node. But, because they are on stack, they have the same address. So all the left and right children will point to the same location.

You probably wanted to allocate them on heap using new or shared_ptr.

<div id="myDiv1" class="myDiv" title="This is Tooltip">body text </div>

As shown above, the current tooltip text is: This is Tooltip

What I want to do is using jquery, appned / add more text to this. For example,

This is toopltip for myDiv1

I have tried, but these don't seem to work and most don't return anything some return undefined, please help;

$('#myDiv1').attr("title", $('#myDiv1').tooltip + "" + "\nSome new text to append"); $('#myDiv1').prop("tooltipText", $('#myDiv1').tooltipText + "" + "\nSome new text to append"); $('#myDiv1').attr("data-original-title", $('#myDiv1').tooltipText + "" + "\nSome new text to append");

16536715 0 PHP generated XML parsing failed

In my CodeIgniter 2.x project with PHP 5.3.x I use following function to render Dom Document as XML response. Every things are goes fine. But generated XML parsing failed due to some malformed unexpected text (non-whitespace text outside root element).

function renderDOMAsXML(DOMDocument &$dom, $format = true, $status = 200){ $dom->formatOutput = $format; $controller = &get_instance(); $controller->output->set_status_header($status); $controller->output->set_header('Content-type: application/xml; charset=utf-8'); $controller->output->set_output($dom->saveXML()); }

for my curiosity I decoded the malformed unexpected text (non-whitespace text outside root element) as hexadecimal format as following.

\x00ef\x00bb\x00bf\x00ef\x00bb\x00bf\x00ef\x00bb\x00bf\x00ef\x00bb\x00bf\x00ef\x00bb\x00bf

\x{00ef}\x{00bb}\x{00bf}\x{00ef}\x{00bb}\x{00bf}\x{00ef}\x{00bb}\x{00bf}\x{00ef}\x{00bb}\x{00bf}\x{00ef}\x{00bb}\x{00bf}

or like this

Change this

onclick= "SaveData();"

onclick= "SaveData(this);"

Then change the saveData function to

function SaveData(elem) { localStorage["LessonID"] = $(elem).attr('LessonID'); localStorage["SubjectName"] = $(elem).find('.lesson_subject').text(); }

Or even better, you can use $.on like @James Allardice showed in his answer.

You could just simplify your query to:

WITH MyQueryAlias1 AS (30 minutes sql query here) SELECT q1.field1 FROM MyQueryAlias1 q1 JOIN MyQueryAlias1 q2 ON q1.field2 = q2.field3

Which will get rid of the second sub-query factoring clause.

This might also work:

WITH MyQueryAlias1 AS (30 minutes sql query here) SELECT field1 FROM MyQueryAlias1 WHERE LEVEL = 1 AND ( field2 = field3 OR CONNECT_BY_ISLEAF = 0 ) CONNECT BY NOCYCLE PRIOR field2 = field3 AND LEVEL = 2;

40148793 0 Can I use the child selector for the media query?

I have some media queries in a class and they're working absolutely fine, but the Chrome browser displays it wrongly as the only browser. So I used a browser hack for the other classes but I don't know how to target the media query. I tried this inside the browser hack:

.firstclass > h1 > @media(min-width: 1620px) { font-size: 3.7vw; }

But my code editor says that "media definitions require block statements after any features", so it seems that it takes it as a new media query...

How can I target it correctly? Isn't the media query a child of the class?

I think your problem is with the declaration of overFeature and outFeature.

Actually, while onSelect and onUnselect are template methods, designed to be overriden, overFeature and outFeature are not. Overriding those methods cause the override of the default behaviour ( layer.drawFeature(feature, style); ).

Anyway, I'd suggest you to use events instead. Try with

selectControlHover.events.register('featurehighlighted', null, function(e) { console.log('feature selected ', e.feature); });

Also, I'm quite sure that you can use one single control instead of two, but not knowing what you're trying to do, I can't suggest you another approach.

I've made some boxes which will be be expanded and hidden by clicking on the titles of the boxes. I've just used slideToggle() for making it. I need another effect. Here is my fiddle: http://jsfiddle.net/qheJQ/

On that, I have three boxes: Slow Task, Different type of Task and Quick Tasks When anyone click on the Slow Task, the box will be expanded. If user click on Slow Task again, that box will be hidden. if user don't click again for hiding the Slow Task box and click Different type of Task, both the box will remain expanded. So, I want, when user click on Different type of Task, this box will be expanded and other boxes will be hidden if they are extended just like this accordion.

Header Authentication

there are three ways to do it

HTTP Basic Authentication
HTTP Digest Authentication
Roll our own using custom HTTP headers

You can read more from PHP Manual

Restler 1.0 had a Digest Authentication example. I've modified to make it work with Restler 2.0

class DigestAuthentication implements iAuthenticate { public $realm = 'Restricted API'; public static $user; public $restler; public function __isAuthenticated() { //user => password hardcoded for convenience $users = array('admin' => 'mypass', 'guest' => 'guest'); if (empty($_SERVER['PHP_AUTH_DIGEST'])) { header('HTTP/1.1 401 Unauthorized'); header('WWW-Authenticate: Digest realm="'.$this->realm.'",qop="auth",nonce="'. uniqid().'",opaque="'.md5($this->realm).'"'); throw new RestException(401, 'Digest Authentication Required'); } // analyze the PHP_AUTH_DIGEST variable if (!($data = DigestAuthentication::http_digest_parse($_SERVER['PHP_AUTH_DIGEST'])) || !isset($users[$data['username']])) { throw new RestException(401, 'Wrong Credentials!'); } // generate the valid response $A1 = md5($data['username'] . ':' . $this->realm . ':' . $users[$data['username']]); $A2 = md5($_SERVER['REQUEST_METHOD'].':'.$data['uri']); $valid_response = md5($A1.':'.$data['nonce'].':'.$data['nc'].':'.$data['cnonce'].':'.$data['qop'].':'.$A2); if ($data['response'] != $valid_response) { throw new RestException(401, 'Wrong Credentials!'); } // ok, valid username & password DigestAuthentication::$user=$data['username']; return true; } /** * Logs user out of the digest authentication by bringing the login dialog again * ignore the dialog to logout * * @url GET /user/login * @url GET /user/logout */ public function logout() { header('HTTP/1.1 401 Unauthorized'); header('WWW-Authenticate: Digest realm="'.$this->realm.'",qop="auth",nonce="'. uniqid().'",opaque="'.md5($this->realm).'"'); die('Digest Authorisation Required'); } // function to parse the http auth header private function http_digest_parse($txt) { // protect against missing data $needed_parts = array('nonce'=>1, 'nc'=>1, 'cnonce'=>1, 'qop'=>1, 'username'=>1, 'uri'=>1, 'response'=>1); $data = array(); $keys = implode('|', array_keys($needed_parts)); preg_match_all('@(' . $keys .

CSS

This is due to the border having to fit in with whatever the triangles height is. Just change with the width in .triangle-left and you will see the responsiveness.

It will only resize up to 500px high though but this should be more than adequate.

.contain { width: 100%; } /*Left pointing*/ .triangle-left { width: 5%; height: 0; padding-top: 5%; padding-bottom: 5%; overflow: hidden; } .triangle-left:after { content: ""; display: block; width: 0; height: 0; margin-top:-500px; border-top: 500px solid transparent; border-bottom: 500px solid transparent; border-right: 500px solid #4679BD; }

<div class="contain"> <div class="triangle-left"></div> </div>

SVG

The SVG version just requires positioning.

.contain { height: 30px; }

<div class="contain"> <svg width="100%" height="100%" viewBox="0 0 500 500"> <polygon points="0,250 500,0 500,500" style="fill:red;stroke:black;stroke-width:2" /> </svg> </div>

A very simple GUI application is possible sticking with C and Windows API only.

In short, you have to register your own Window class (RegisterClassEx), then create the window (CreateWindowEx). Note that your window class main element is its (WindowProc) that receive the messages and that you have to implement to act as you want. After that, your C program should run the message pump (PeekMessage and DispatchMessage) for Windows to do its stuff and allow interacting with your window.

See the MSDN documentation for these functions to get help and examples.

You call a class method by appending the class name likewise:

class.method

In your code something like this should suffice:

Test.static_init()

You could also do this:

static_init(Test)

To call it inside your class, have your code do this:

Test.static_init()

My working code:

class Test(object): @classmethod def static_method(cls): print("Hello") def another_method(self): Test.static_method()

and Test().another_method() returns Hello

If you use jquery datatables you can do something like this in your click event:

var columnIndexToSort = 0, sortAcending = true; $("#table").fnSort([[columnIndexToSort, sortAcending ? 'asc' : 'desc']]);

This will cause jquery datatables to sort and redraw the table for you. The jquery datatables plugin is very powerful and I find it harder to find something it can't do rather than something it can.

1847105 0 How to determine which assembly a specific class belongs to?

Often i have a problem that I need to determine which assebmly to include into my project in order to use specific class. For instance I want to you TypeInfo class. MSDN does not say it belongs to. Actually I am not even been able to find TypeInfo class using MSDN document explorer search. All the results relate to some other stuff. For instance first result is about System.Runtime.Remoting.

Also MSDN says - assembly mscorlib. In the components page of Add Reference dialog box i can see mscorlib but also fully qualified names like System.RunTime.Serialization

What is the difference?

WordPress doesn't have wp_dropdown_posts just like it has wp_dropdown_categories and wp_dropdown_users.

It has to be made by hand with get_posts or WP_Query, loop the results and make the <select><option>. For your use case, I think you'll need to use the Custom Fields parameters.

You can find a sample code at WPSE: Dropdown list of a custom post type.

The problem is that the InPageAppender relies on log4javascript's own page load handling code to know whether it can start drawing itself. When loaded via RequireJS, the page is already loaded and log4javascript's page load handling code never runs.

You can get around this by calling log4javascript.setDocumentReady(). The most sensible place to do this would seem to be in the shim init() function, but I'm no expert in RequireJS so there may be a better way:

requirejs.config({ shim: { 'log4javascript': { exports: 'log4javascript', init: function() { log4javascript.setDocumentReady(); } } } });

I have an app need login, I use a singleton http client to do everything, so it can track the cookies for me.

But when I launch a browser intent in my app to view some html pages, the app sometimes be killed by low memory, when user come back from the browser, my app activity would be recreated, but the new http client would not contains that login session id.

So I think what I need is to cache the cookies when my app get killed, and then restore it back when the app got recreated. I know there is a CookieSyncManager, but I do not have a full picture of how to use that.

(1) So How can I do that? is Cookie seralizable, I just thought to cache it in the sdcard, maybe a bad idea.

Another more general question maybe:

(2) How to share httpclient with webview/system browser? Not just pass cookies from httpclient to webiew/browser, but also get the cookies when initialize the cookies, How to make the http client and webview/browser share just ONE copy of cookie store in any time?

It looks like you can remove the transform on the second image and it will go back behind the first one. So in other words, on image click I would probably first remove all occurrences of the transform property before applying to the clicked image.

Or you could also set both images to position:relative and then on click set the z-index to something like 5 and set all other images to something below it such as 3. But again, you'll need to clear these inline styles so that when another image is clicked there are remnants from before that give you un-clear results.

TextViews can only contain a small subset of HTML tags not CSS. These tags include <strong>, <underline>, <emphasis>, <p>, <small>, <medium> etc. There are a few others as well.

You can change the font and font colour by doing something like

<p font-color="blue">This is my blue text</p>

but you can't add CSS. If you need to do formatting in this way that would require CSS then a webview would be better.

37996425 0 Resize CGSize to the maximum with keeping the aspect-ratio

I have a CGSize objects that I need to send to my server. The maximum size I can send to the server is 900*900 (900 width/900 height).

There are some objects that are larger the 900*900 and I want to write a function that resizes them to the maximum (as I already say, the maximum is 900*900) but to keep the aspect ratio.

For example: if I have an object that is 1,000px width and 1,000px height I want the function to return a 900*900 object. If I have an object that is 1920px width and 1080px height I want it to return the maximum size possible with keeping the ratio.

Anyone have any idea how can I do that?

Thank you!

OriginalUser2 answer:

I've tried this code:

let aspect = CGSizeMake(900, 900) let rect = CGRectMake(0, 0, 1920, 1080) let final = AVMakeRectWithAspectRatioInsideRect(aspect, rect)

final is {x 420 y 0 w 1,080 h 1,080}, I can't understand why the x = 420, but anyway 1080*1080 is not in the same aspect ratio as 1920*1080 and it's bigger than 900*900.

Can you explain a bit more?

HTTP is a pretty simple protocol, the following should get the status code out pretty reliably (updated to be a tad more robust):

int statusCodeStart = httpString.IndexOf(' ') + 1; int statusCodeEnd = httpString.IndexOf(' ', statusCodeStart); return httpString.Substring(statusCodeStart, statusCodeEnd - statusCodeStart);

If you really wanted to you could add a sanity check to make sure that the string starts with "HTTP", but then if you wanted robustness you could also just implement a HTTP parser.

To be honest this would probably do! :-)

httpString.Substring(9, 3);

You are probably getting this error because Access' Tabledefs list does not always immediately reflect changes you make, i.e. a delete. You can refresh it with CurrentDB.TableDefs.Refresh after any .Appends and/or .Deletes, but this takes time, and considering that refreshing linked tables takes a significant amount of time each, time is something you may not be able to afford.

It is better practice to check your TableDefs for pre-existing links and refresh them, not delete and recreate them, as deleting them also deletes any formatting, such as column widths and field formats that a refresh would leave unchanged.

If you have tables that need their links refreshed, change the .Connect property, then use CurrentDB.TableDefs(TableName).RefreshLink

You should only be using CurrentDb.TableDefs.Delete tdf.Name when the source table no longer exists.

I use a method similar to this myself, however I also store the date and time of the last linked table refresh, and only refresh those tables that had their schema modified after that time. With a hundred or more table links and 2+ seconds per table to refresh the links, I need to save all the time I can.

Now, a web application may be a part of a whole website. A website is comprehended of web applications. Though usually you'll see that a website has only one web application.

Add <base href="/demo/"> to your head or /demo/ to your links. The problem is, that you haven't told the browser to look in your subfolder.

You can easily validate your links: just click on them, analyse the browser's addressbar and correct what's missing or extra in the address shown there.

11495856 0 Actionscript 3: Healthbar and Button

So basically I am making a game in which a button is clicked to decrease the amount of health in a healthbar. I have a button on the stage named fortyfivedown_btn, and a healthbar, which is a 101 frame (includes zero) movieclip. The health bar has an instance name of lifebar. On the stage, the button coding is:

fortyfivedown_btn.addEventListener(MouseEvent.CLICK, fortyfivedownClick); function fortyfivedownClick(event:MouseEvent):void{ lifebar.health = lifebar.health-45; }

Inside the healthbar movieclip, I have a layer of coding that is:

var health:int = 100; gotoAndStop(health + 1); if(health < 0) health = 0; else if(health > 100) health = 100; gotoAndStop(health + 1);

So, there is my coding. The thing is, when the button is clicked, the healthbar does not go down. I traced the health variable in the button:

 fortyfivedown_btn.addEventListener(MouseEvent.CLICK, fortyfivedownClick); function fortyfivedownClick(event:MouseEvent):void{ lifebar.health = lifebar.health-45; } { trace(lifebar.health); }

35239284 0 using compass mixins in scss files compiled by gulp in Laravel Elixir

I want to use Compass mixins and Capabilities in scss files that should compiled with Gulp tasks in laravel Elixir.

For example , I have two scss files named my-styles.css and app.scss in resource/assets/sass directory :

This is my-styles.scss file :

@import "compass/css3"; body{ opacity: 1.0; animation: test; color: red; text-align: center; a:link{ background-color: red; text-decoration: none ; &.span{ color: red; @include border-radius(5px); } } }

And this is app.scss file Content :

a{ transform: scale(1.1); transform: rotate(30deg) scale(10); }

And to compile this scss files and combine them to a file name all.css in public/css directory , I write this :

var elixir = require('laravel-elixir'); var gulp = require('gulp'); var compass = require('gulp-compass'); var sass = require('gulp-sass'); gulp.task('compile', function () { return gulp .src(['my-styles.scss', 'app.scss']) .pipe(sass({compass: true, sourcemap: true, style: 'compressed'})) .pipe(gulp.dest('public/css/all.css')); }); elixir.config.sourcemaps = false; elixir(function (mix) { mix.task('compile'); });

after running gulp command in console this messages are shown:

D:\wamp\www\newProject>gulp [12:36:48] Using gulpfile D:\wamp\www\newProject\gulpfile.js [12:36:48] Starting 'default'... [12:36:48] Starting 'task'... [12:36:48] Starting 'compile'... [12:36:48] Finished 'task' after 17 ms [12:36:48] Finished 'default' after 21 ms [12:36:48] Finished 'compile' after 26 ms

But No file is created in public directory.

what is Problem ?

Refer to this SO Discussion which details the reasons for a problem similar to yours.

BETWEEN 'a' and 'b' actually matches to columnValue >='a' and columnValue <= 'b'

In your case w52 is greater than w5 due to lexicographic ordering of Strings - this means that the BETWEEN clause will never return a true (think about it as equivalent to saying BETWEEN 10 and 1 instead of BETWEEN 1 and 10.

Edit to my response:

Refrain from storing the week value as a string. Instead here are a couple of approaches in order of their preference:

Have a timestamp column. You can easily then use MySQL query facilities to extract the week information out of this. For a reference see this post.
Maintain two columns - YEAR, WEEKNO where YEAR will store values like 2015, 2016 etc and WEEKNO will store the week number. This way you can query data for any week in any year.

Since the statements are in a try block there's a chance that they will fail, and your program has a chance of trying to use a non-initialized variable. The solution is to initialize the variables to a default value that makes sense, i.e.,

int guess = -1; // some default value

You should also wrap the while loop around the try/catch block. Don't let the program progress until inputted data is valid.

boolean validGuess = false; while (!validGuess) { // prompt user for input here try { guess = Integer.parseInt(iConsole.nextLine()); if (/* .... test if guess is valid int */ ) { validGuess = true; } } catch (NumberFormatException e) { // notify user of bad input, that he should try again } }

You could even encapsulate all of this into its own method if you need to do similar things throughout the program.

Firstly, you have not measured the speed of len(), you have measured the speed of creating a list/set together with the speed of len().

Use the --setup argument of timeit:

$ python -m timeit --setup "a=[1,2,3,4,5,6,7,8,9,10]" "len(a)" 10000000 loops, best of 3: 0.0369 usec per loop $ python -m timeit --setup "a={1,2,3,4,5,6,7,8,9,10}" "len(a)" 10000000 loops, best of 3: 0.0372 usec per loop

The statements you pass to --setup are run before measuring the speed of len().

Secondly, you should note that len(a) is a pretty quick statement. The process of measuring its speed may be subject to "noise". Consider that the code executed (and measured) by timeit is equivalent to the following:

for i in itertools.repeat(None, number): len(a)

Because both len(a) and itertools.repeat(...).__next__() are fast operations and their speeds may be similar, the speed of itertools.repeat(...).__next__() may influence the timings.

For this reason, you'd better measure len(a); len(a); ...; len(a) (repeated 100 times or so) so that the body of the for loop takes a considerably higher amount of time than the iterator:

$ python -m timeit --setup "a=[1,2,3,4,5,6,7,8,9,10]" "$(for i in {0..1000}; do echo "len(a)"; done)" 10000 loops, best of 3: 29.2 usec per loop $ python -m timeit --setup "a={1,2,3,4,5,6,7,8,9,10}" "$(for i in {0..1000}; do echo "len(a)"; done)" 10000 loops, best of 3: 29.3 usec per loop

(The results still says that len() has the same performances on lists and sets, but now you are sure that the result is correct.)

Thirdly, it's true that "complexity" and "speed" are related, but I believe you are making some confusion. The fact that len() has O(1) complexity for lists and sets does not imply that it must run with the same speed on lists and sets.

It means that, on average, no matter how long the list a is, len(a) performs the same asymptotic number of steps. And no matter how long the set b is, len(b) performs the same asymptotic number of steps. But the algorithm for computing the size of lists and sets may be different, resulting in different performances (timeit shows that this is not the case, however this may be a possibility).

Lastly,

If the creation of a set object takes more time compared to creating a list, what would be the underlying reason?

A set, as you know, does not allow repeated elements. Sets in CPython are implemented as hash tables (to ensure average O(1) insertion and lookup): constructing and maintaining a hash table is much more complex than adding elements to a list.

Specifically, when constructing a set, you have to compute hashes, build the hash table, look it up to avoid inserting duplicated events and so on. By contrast, lists in CPython are implemented as a simple array of pointers that is malloc()ed and realloc()ed as required.

Yes, you can do this by implementing ISerializationSurrogate and ISurrogateSelector interfaces.

Something like this:

[AttributeUsage(AttributeTargets.Class)] public class SerializeLinqEntities : Attribute { } public class LinqEntitiesSurrogate : ISerializationSurrogate { public void GetObjectData( object obj, SerializationInfo info, StreamingContext context) { EntitySerializer.Serialize(this, obj.GetType(), info, context); } public object SetObjectData( object obj, SerializationInfo info, StreamingContext context, ISurrogateSelector selector) { EntitySerializer.Deerialize(obj, obj.GetType(), info, context); return obj; } } /// <summary> /// Returns LinqEntitySurrogate for all types marked SerializeLinqEntities /// </summary> public class NonSerializableSurrogateSelector : ISurrogateSelector { public void ChainSelector(ISurrogateSelector selector) { throw new NotImplementedException(); } public ISurrogateSelector GetNextSelector() { throw new NotImplementedException(); } public ISerializationSurrogate GetSurrogate( Type type, StreamingContext context, out ISurrogateSelector selector) { if (!type.IsDefined(typeof(SerializeLinqEntities), false)) { //type not marked SerializeLinqEntities selector = null; return null; } selector = this; return new LinqEntitiesSurrogate(); } } [SerializeLinqEntities] public class TestSurrogate { public int Id { get; set; } public string Name { get; set; } } class Program { static void Main(string[] str) { var ns1 = new TestSurrogate {Id = 47, Name = "TestName"}; var formatter = new BinaryFormatter(); formatter.SurrogateSelector = new NonSerializableSurrogateSelector(); using (var ms = new MemoryStream()) { formatter.Serialize(ms, ns1); ms.Position = 0; var ns2 = (TestSurrogate) formatter.Deserialize(ms); // Check serialization Debug.Assert(ns1.Id == ns2.Id); Debug.Assert(ns1.Name == ns2.Name); } } }

In standard C++ there is no such thing as a stack. The standard only differentiates between the different lifetimes of objects. In that case a variable declared as T t; is said to have automatic storage duration, which means it life-time ends with the end of it's surrounding scope. Most (all?) compilers implement this through a stack. It is a reasonable assumption that all objects created that way actually live on the stack.

Replace every occurrence of TODAY() with DATE(2011,9,1):

=YEAR(DATE(2011,9,1))-YEAR(C2)-1 + (MONTH(DATE(2011,9,1))>MONTH(C2)) + (MONTH(C2)=MONTH(DATE(2011,9,1)))*(DAY(DATE(2011,9,1))>=DAY(C2))

For a person born on the date in cell C2, this would give what their age will be on Sept 1, 2011.

Edit: Or, more simply, try this:

=2011-YEAR(C2)-1 + 9>MONTH(C2) + (MONTH(C2)=9)*(1>=DAY(C2))

22009556 0 OpenCV SURFDetector Range of minHessian

I'm using the OpenCV SURFDetector to search for keypoints in an image. In my program I want to give the user the opportunity to set the value of the minHessian with a trackbar, but this means that I would have to know the range of the hessian-values.

I know that the higher I set this threshold the less keypoints I get and vice versa.

Is there a way to calculate a range of the hessian values so I can set 0 (which would be a very high minHessian threshold) on my trackbar to “no keypoints” and 100 (which is probably minHessian=1 or 0) for “all possible keypoints”?

I’ve already taken a look at this question, but this doesn’t help me out here: Whats the meaning of minHessian (Surffeaturedetector)

Edit: I've found a way for my application that works, but I'm not happy with this solution. This is what I am doing now: I constantly raise my minHessian and check if I still find keypoints, but this variant is neither fast nor really exact because I have to take bigger steps (in my case i+=100) to get results faster. I'm pretty sure there is another solution. What about binary search or something similar? Is it really not possible to calculate the maxHessian value?

Here's my code:

C#-side:

private int getMaxHessianValue() { int maxHessian = 0; for (int i = 0; i < 100000; i+=100) { int numberOfKeypoints = GetNumberOfKeypoints(pathToImage, i); if (numberOfKeypoints == 0) // no keypoints found? -> maxHessian { maxHessian = i; break; } } return maxHessian; }

C++-side:

int GetNumberOfKeypoints(char* path, int minHessian) { /// Load image Mat templ; templ = imread( path, CV_LOAD_IMAGE_GRAYSCALE ); // Detect the keypoints using SURF Detector SurfFeatureDetector detector( minHessian ); std::vector<KeyPoint> keypoints; detector.detect( templ, keypoints ); // return number of keypoints return keypoints.size(); }

13770409 0 Re-load Unloaded Projects in EnvDTE

I have listed all the projects in my solution, using EnvDTE, but I found a bug in my code: I can't get the projects that are Unloaded.

I found a way to skip the Unloaded projects:

if (string.Compare(EnvDTE.Constants.vsProjectKindUnmodeled, project.Kind, System.StringComparison.OrdinalIgnoreCase) == 0) continue;

This way, my code doesn't crash - but I am unable to load the missing projects through code, since they exist already.

How can I Load the Unloaded projects into the solution ?

I have tried:

project.DTE.ExecuteCommand("Project.ReloadProject");

And got error:

System.Runtime.InteropServices.COMException (...): Command "Project.ReloadProject" is not available.

So I tried to somehow get

application.DTE.ExecuteCommand("Project.ReloadProject");

But before that, from every place I searched on the NET, I must pre-select the project in the solution - and for that, I need project.Name (which I have), and the path, which I don't (every example I have found assumes that the solution path is the same as the project path, which is highly unlikely in a generic situation).

you're not implementing background processes, you're trying to start a background process using the syntax of the already-implemented-shell on your computer (but honestly, it's pretty hard to tell what's going on with that indentation. That's really bad. Can you make it readable, please?). That '&' character is recognised by your shell, not by execvp.

Note I'm assuming you just have the data part of the string, not an entire JSON fragment - i.e.

string s = @"blah \u003c blah \u00252 blah";

If the above assumption is wrong and you have a full JSON fragment, just use JavaScriptSerializer to get an object from the data.

Annoyingly, HttpUtility has encode but not decode.

You could spoof the string into a full JSON object, though - this seems a bit overkill:

class Dummy { public string foo { get; set; } } static void Main(string[] args) { string s = @"blah \u003c blah \u00252 blah"; string json = @"{""foo"":""" + s + @"""}"; string unencoded = new JavaScriptSerializer().Deserialize<Dummy>(json).foo; }

The issue might be that you are trying to Uri encode an already Uri encoded string.

As per the Intent class documentation for the toUri() method:

Convert this Intent into a String holding a URI representation of it. The returned URI string has been properly URI encoded, so it can be used with Uri.parse(String). The URI contains the Intent's data as the base URI, with an additional fragment describing the action, categories, type, flags, package, component, and extras.

So try:

String finaldata = Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME));

8409762 0 2 column floating layout, does width have to be specified for left column

If one uses float:left to layout two columns, does the left column have to have a width specified? Without a width assigned, when I shrink the width of the browser page, the second (main) column gets put underneath the left (navigation) column. Is there a way to avoid this, without assigning a width? If not, what is the least width spec's I need to add? I.e. can I assign a fixed pixel width to the left column, and have the right column get the rest?

Thanks

You are checking for Submit in $_POST, but the method specified in the form is GET.

To have it work, change the PHP code to look for $_GET['Submit'].

(But I'd move instead everything, form method included, to POST).

That said, your script seems to have been pasted twice, the second version using $q instead of $trimmed (is $q defined?), and a SQL table called 'table' instead of 'questions':

// get results $query = "SELECT * FROM table WHERE question LIKE '%$q%' OR name LIKE '%$q%' or detail like '%$q%'"; $result = mysql_query($query) or die("Couldn't execute query");

This is strange, if I'm reading your code correctly. Is there a reason that you can't maintain the collection and modify it (as opposed to re-creating it) so that you don't need to RaisePropertyChanged at all? That's what ObservableCollection(of T) does, after all.

As I'm reading it, it might as well be an IEnumerable(of T).

(Creating a new ObservableCollection(of T) in a property getter is almost always a mistake. A ReadOnlyObservableCollection(of T) makes a lot more sense in that context.)

As you said in the answers above, the field got manually removed from the database, so the migration tries to delete a field that is no longer existing in the database.

Normally you should never delete fields directly in the db but use the migrations instead. As the field is already gone you can now only fake the migration to tell django that the changes were already made:

manage.py migrate rentals 0002 --fake

Make sure though that you are at migration 0001, otherwise that would be faked aswell.

just to be sure, you could run the following command first:

manage.py migrate rentals 0001

 For(int i = 0; i< sL.length; i++){ String wavFileName = sl[i] + ".wav"; // do whatever you need to do here }

For on demand (press a button get a specific sound) then Jeroen's idea of using a map will work.

Ok i think i understand your problem :

The after_destroy method in PictureFileCallbacks will be auto-magically called by rails :

When rails destroys your PictureFile object, it will instantiate a PictureFileCallbacks object and try to run an after_destroy method in it.

Everything works by convention, if you follow the naming properly everything will work out of the box.

Try it on a dummy project, and if you have some trouble making this work come back with some code to show.

A stop-gap measure would be to insert one (or several) line(s) of

DoEvents

after the change and before ActiveWindow....NextHeaderFooter. That command yields execution to the OS. That may give Word the time it needs to catch up.

Of course, you would do better to avoid using ActiveWindow... altogether and iterate through the sections with a For loop.

I think all you need to have is a so called application defined in your Wowza Streaming Servier, which I guess you already have. This application, let's suppose it's called live can receive multiple live streams from different sources, e.g. GoCoders. Each source can publish a stream with custom name into your application, and then you can choose which one to play in your JW Player's setup, by specifying the stream name in the URL.

(It's not clear to me if you wanted to play multiple videos simultaneously in the same JW Player instance, in a picture-in-picture style.)

20306465 0 iterating through PictureBoxes in visual c++

I'm programming in visual c++, and i have about 60 pictures (indexed p0...p63), and i want to make a loop that goes through all the pictures and change their ImageLocation under some conditions.

I figured the Tag property and one of my attempts was like this: i tagged my pictures from 0 to 63 and then tried the following:

for(int i=0; i<64; i++) { PictureBox->Tag[i]->ImageLocation="possible-.gif"; }

It's not working... I get this error:

syntax error : missing ';' before '->' line: 1514 syntax error : missing ';' before '->' line: 1514

(twice, same line)

What's the right way of doing it?

Thank you!

edit:

OK now i have the pictures in an array. Is there a way to have a common rule for all of them? I want to make a click event for each and every one of the pictures. Is the only way setting a rule for each independently? Or can i set a rule for the array itself by saying something like:

if(Pictureboxes[i]_Clicked) { Pictureboxes[i].something = "something else"; }

26658216 0 Excel Macro - Windows().Activate not taking value

The code that works is the following:

Windows("Contract Drilldown (3).xls").Activate

When I use :

 Windows(Chr(34) & ddlOpenWorkbooks.Value & Chr(34)).Activate

I get:

Runtime Error '424': Object Required

If I use a String Variable to pass in the values i.e.:

Dim wbn As String wbn = "Contract Drilldown (3).xls" Windows(Chr(34) & wbn & Chr(34)).Activate

I get:

Run-time error '9': Subscript out of range

And if I use

wbn = ddlOpenWorkbooks.Value Windows(Chr(34) & wbn & Chr(34)).Activate

I also get

Runtime Error '424': Object Required

Anyone have any idea how I can pass in the ddlOpenWorkbooks.Value in without getting an error?

Edit - More Info

Ok so the application looks like this: enter image description here

the full code block for the Import Data Button is:

Public Sub Data_Import() Windows(ddlOpenWorkBooks.Value).Activate Columns("A:V").Select Selection.Copy Omni_Data.Activate Range("A1").Select ActiveSheet.Paste Omni_Data.Range("A:Z").Interior.ColorIndex = 0 Omni_Data.Range("A:Z").Font.Name = "Segoe UI" Omni_Data.Range("A:Z").Font.Name = "Segoe UI" 'Setting Background Colour to white and changing font End Sub

The above Sub is called on Click Event for the button.

As a test the close button has the following code:

Private Sub cmdCancel_Click() MsgBox (ddlOpenWorkbooks.Value) End End Sub

Which works fine:

enter image description here

Update

So we have found the problem.

As this is being called from a module it didn't know where ddlOpenWorkbooks was and where to pull that data from.

The corrected code in the Sub is:

Public Sub Data_Import() Windows(frmOmniDataManipulation.ddlOpenWorkbooks.Value).Activate Columns("A:V").Select Selection.Copy Omni_Data.Activate Range("A1").Select ActiveSheet.Paste Omni_Data.Range("A:Z").Interior.ColorIndex = 0 Omni_Data.Range("A:Z").Font.Name = "Segoe UI" Omni_Data.Range("A:Z").Font.Name = "Segoe UI" 'Setting Background Colour to white and changing font End Sub

This will allow me to call the sub.

Thanks All!

11193167 0 intercept data changes and alter/validate from a server

I'm working on a solution to intercept changes to the data from our node.js server and validate/alter them before they are stored/synced to other clients.

Any strategies or suggestions on how to solve this with the current code base?

Currently, it seems like the only option is to rewrite it post-sync operation. That would mean each client would probably receive the sync (including the server), then the server would rewrite the data and trigger a second sync.

To help understand the context of the question, here's what seems like an ideal strategy for my needs:

server gets a special token/key not available to clients (when security comes about)
server registers a dependency injection like firebase.child('widgets').beforeSync(myCallback)
client syncs data
server callback is notified
server modifies or validates the data
if valid, it returns it to firebase for sync ops
if invalid, aborts the sync with an error which is returned to the client

I am trying to obtain a handle on one of the views in the Action Bar

I will assume that you mean something established via android:actionLayout in your <item> element of your <menu> resource.

I have tried calling findViewById(R.id.menu_item)

To retrieve the View associated with your android:actionLayout, call findItem() on the Menu to retrieve the MenuItem, then call getActionView() on the MenuItem. This can be done any time after you have inflated the menu resource.

The highest available version of GCC in the 12.04 repositories is 4.6. You can use the package manager to install a newer version, but you will have to add a PPA. This link should help, although it is for a slightly older version of GCC (but can be used for the newest version).

As a commenter pointed out, if your own built version of GCC was compiled with the --prefix parameter, the entire installation should be in that directory under /usr/local or wherever you installed it, and can be removed.

The access token returned in the call to the OAuth2 endpoint identifies the caller and privileges (which api calls you can make). This is required for any of the api calls (REST) to create payments, execute, refunds etc. Some calls require more privileges than others, i.e. you need to have requested more information or provided more credentials when createing the access token.

The token returned in the URL identifies the payment, this is so that when a user is redirected back to your site, you have a way to identify which payment has been redirected back to your site and identify the proper information, i.e. execute the correct payment.

17364133 0 How can I update a file incrementally in iOS. (File patching)

I have a huge text file in my application (version 1.0).

Lets assume that a new version (2.0) of this file was just released. Most of the file remained the same but the new (2.0) version has a few modifications (some lines removed, others added).

I now wish to update the file (1.0) to the new version (2.0), but do not wish to download the whole file again. I would love to just patch the file with the changes of the new file, thus saving bandwith from downloading the WHOLE new file from my server. (Similar to the way versioning systems like git or svn act)

How can I do this programmatically? Are there any iOS libraries available?

Thank you

ListBox ItemsSource="{**Binding**}" IsSynchronizedWithCurrentItem="true"/>

Note that although we have emphasized that the Path to the value to use is one of the four necessary components of a binding, in the scenarios which you want to bind to an entire object, the value to use would be the same as the binding source object. In those cases, it is applicable to not specify a Path. Consider the following example:

28339893 0 Why is IIS exiting with code 0 whenever I preview in Chrome from Visual Studio?

I started on a new asp.net site yesterday with vb.net; I am familiar with VB.NET but not ASP.NET.

My primary browser is Google Chrome, but when I attempt to 'emulate' (debug) the site, the debugger exits the local development server spawned by Visual Studio and as a result, Chrome can never load the website (since when it tries to the webserver isn't running). This can be seen easily by viewing Chrome and Visual Studio side-by-side; Visual Studio's status bar turns orange for a second or so then goes back to blue, and IIS exits with code 0:

The program '[73048] iisexpress.exe: Program Trace' has exited with code 0 (0x0). The program '[73048] iisexpress.exe' has exited with code 0 (0x0).

However this can be temporarily fixed by 'emulating' in Internet Explorer and then with Chrome again, but this fix must be applied on every reboot in order for it to work.

Why is this happening, and how can I properly debug in Chrome without the webserver exiting?

I read How can I prevent Visual Studio 2013 from closing my IIS Express app when I end debugging? but however none of the solutions helped me in this respect, and that the issue is that Visual Studio seems to be closing iisexpress.exe when the debugging has started.

Chrome runs each tab in a separate process (sandboxing), so perhaps it could be that Visual Studio is expecting Chrome's 'base' PID when Chrome actually spawns an entirely new PID for the new tab created when the 'emulator' starts?

Is there any solution to this other than use Internet Explorer (or the 'fix') for debugging the site?

I have recorded what's happening here, and I still find it odd that Internet Explorer is able to 'cure' the problem temporarily.

I am using Visual Studio 2013 Ultimate with Windows 8.1 Pro (Media Centre Edition) and Chrome 40.0.2214.93 m.

^{Updated after rereading the question.}
You are mixing GROUP BY and DISTINCT ON. What you want (how I understand it) can be done with a window function combined with a DISTINCT ON:

SELECT DISTINCT ON (a) a, b, c , count(d) OVER (PARTITION BY a, b, c) AS d_ct , e FROM tbl ORDER BY a, d_ct DESC;

Window functions require PostgreSQL 8.4 ore later.

What happens here?

Count in d_ct how many identical sets of (a,b,c) there are in the table with non-null values for d.
Pick exactly one row per a. If you don't ORDER BY more than just a, a random row will be picked.
In my example I ORDER BY d_ct DESC in addition, so a pseudo-random row out of the set with the highest d_ct will be picked.

Another, slightly different interpretation of what you might need, with GROUP BY:

SELECT DISTINCT ON (a) a, b, c , count(d) AS d_ct , min(e) AS min_e -- aggregate e in some way FROM t GROUP BY a, b, c ORDER BY a, d_ct DESC;

GROUP BY is applied before DISTINCT ON, so the result is very similar to the one above, only the value for e / min_e is different.

give bottom margin to your listview: android:layout_marginBottom="60dip"
If you are using RelativeLayout then just give listview as android:layout_above="@+id/footer"

I suggest to you go with 2nd option.

Update:

Based on the XML you have posted, try this correct XML layout:

<RelativeLayout android:id="@+id/relativeLayout1" android:layout_height="wrap_content" android:layout_width="match_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <ListView android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/companylistView" android:layout_above="@+id/textView1"> </ListView> <TextView android:text="Footer Text" android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#000000" android:layout_alignParentBottom="true"> </TextView> </RelativeLayout>

Subscribing to events in VB.NET requires either the AddHandler or Handles keyword. You will also have a problem with the lambda, the Function keyword requires an expression that returns a value. In VS2010 you can write this:

 AddHandler m_switchImageTimer.Tick, Sub(s, e) LoadNextImage()

In earlier versions, you need to either change the LoadNextImage() method declaration or use a little private helper method with the correct signature:

 AddHandler m_switchImageTimer.Tick, AddressOf SwitchImageTimer_Tick ... Private Sub SwitchImageTimer_Tick(sender As Object, e As EventArgs) LoadNextImage() End Sub

You could check if the #localVideo element exists. Also, if they are the only elements in the #A element, you can remove them by calling $('#A').empty();.

$(document).ready(function() { $('#BtnOn').click(function() { if ($('#localVideo').length == 0) { $('#A').append('<video id="localVideo" style="background-color:black"></video><div id="remoteVideos"></div>'); } }); $('#BtnOff').click(function() { if ($('#localVideo').length > 0) { $("#localVideo").remove(); $("#remoteVideos").remove(); } }); });

You could also consider hiding and showing the video elements, rather than adding and removing them.

No, nested collections as properties can not be used.
The philosophy is simple: maximum decomposition of objects and relationships to effectively use graph algorithms as a tool of analysis. Using your example with food:
- Who eats the same foods for breakfast?
- Who was the lunch at the same time?
- What if you need to count calorie meal?
- How different cooking methods of the same person on different days?
- Who supplies these products?
- In some recipes include these products?
- What are the vegetables and fruit juices that people were in the day for breakfast?

And as an illustration of an exemplary model:

While your particular case concerns Windows Azure specific (the 4 minute timeout of LBs), the question is pure IIS / ASP.NET workwise. Anyway, I don't think it is possible to send "ping-backs" to the client while in AsyncController/AsyncPage. This is the whole idea of the AsyncPages/Controllers. The IIS leaves the socket aside having the thread serving other requests. And gets back only when you got the OutstandingOperations to zero with AsyncManager.OutstandingOperations.Decrement(); Only then the control is given back to send final response to the client. And once you are the point of sending response, there is no turning back.

I would rather argue for the architectural approach of why you thing someone would wait 4 minutes to get a response (even with a good animated "please wait")? A lot of things may happen during this time. From browser crash, through internet disruption to total power loss/disruption at client. If you are doing real Azure, why not just send tasks for a Worker Role via a Queue (Azure Storage Queues or Service Bus Queues). The other option that stays in front of you for so long running tasks is to use SingalR and fully AJAXed solution. Where you communicate via SignalR the status of the long running operation.

UPDATE 1 due to comments

In addition to the approach suggested by @knightpfhor this can be also achieved with a Queues. Requestor creates a task with some Unique ID and sends it to "Task submission queue". Then "listens" (or polls at regular/irregular intervals) a "Task completion" queue for a message with given Task ID.

In any way I don't see a reason for keeping client connected for the whole duration of the long running task. There are number of ways to decouple such communication.

6511542 0 Force JavaScript exception/error when reading an undefined object property?

I'm an experienced C++/Java programmer working in Javascript for the first time. I'm using Chrome as the browser.

I've created several Javascript classes with fields and methods. When I read an object's field that doesn't exist (due to a typo on my part), the Javascript runtime doesn't throw an error or exception. Apparently such read fields are 'undefined'. For example:

var foo = new Foo(); foo.bar = 1; var baz = foo.Bar; // baz is now undefined

I know that I can check for equality against 'undefined' as mentioned in "Detecting an undefined object property in JavaScript", but that seems tedious since I read from object fields often in my code.

Is there any way to force an error or exception to be thrown when I read an undefined property?

And why is an exception thrown when I read an undefined variable (as opposed to undefined object property)?

I had the same issue.

But I found another solution. I used the artisan worker as is, but I modified the 'watch' time. By default(from laravel) this time is hardcoded to zero, I've changed this value to 600 (seconds). See the file: 'vendor/laravel/framework/src/Illuminate/Queue/BeanstalkdQueue.php' and in function 'public function pop($queue = null)'

So now the work is also listening to the queue for 10 minutes. When it does not have a job, it exits, and supervisor is restarting it. When it receives a job, it executes it after that it exists, and supervisor is restarting it.

==> No polling anymore!

notes:

it does not work for iron.io queue's or others.
it might not work when you want that 1 worker accept jobs from more than 1 queue.

518082 0 php htmlspecialchars() from one form to another

Why can't htmlspecialchars() continually encode characters after each form submission? Take a look at the following example:

<?php $_POST['txt'] = htmlspecialchars($_POST['txt']); ?> <form method="post"> <input name="txt" value="<?=$_POST['txt'] ?>" /> <input type="submit" name="save" value="test" /> </form>

You can see it at running at http://verticalcms.com/htmlspecialchars.php.

Now do the following

1) Type & into the text field 2) Hit the test button once 3) When the page completes post back, hit the test button again 4) When the page completes post back, view the page source code

In the input box, the value is & amp;

I was expecting & amp; amp;

Why is it not & amp; amp; ???

17935283 0 How to get all the parent classes of a derived class in C# Reflection

It is weird that I was not able to find a similar question but this is what actually I want, finding all the parent classes of a derived class.

I tested a code with a hope that it works for me :

void WriteInterfaces() { var derivedClass = new DerivedClass(); var type = derivedClass.GetType(); var interfaces = type.FindInterfaces((objectType, criteria) => objectType.Name == criteria.ToString(),"BaseClass"); foreach(var face in interfaces) { face.Name.Dump(); } } interface BaseInterface {} class BaseClass : BaseInterface {} class BaseClass2 : BaseClass {} class DerivedClass : BaseClass2{}

Basically, here my main intention is to check if a derived class somehow inherits a base class somewhere in its base hierarchy.

However, this code returns null and works only with interfaces.

2854088 0 Serialize struct with pointers to NSData

I need to add some kind of archiving functionality to a Objective-C Trie implementation (NDTrie on github), but I have very little experience with C and it's data structures.

struct trieNode { NSUInteger key; NSUInteger count, size; id object; __strong struct trieNode ** children; __strong struct trieNode * parent; }; @interface NDTrie (Private) - (struct trieNode*)root; @end

What I need is to create an NSData with the tree structure from that root - or serialize/deserialize the whole tree some other way (conforming to NSCoding?), but I have no clue how to work with NSData and a C struct containing pointers.

Performance on deserializing the resulting object would be crucial, as this is an iPhone project and I will need to load it in the background every time the app starts.

What would be the best way to achieve this?

Thanks!

40310595 1 How to not block making initial connection with python requests?

I have a server that uses requests to make queries to another server that may or may not be running. If that server is not running, I do not want to block for a long time; I can just handle the error right away. However, the timeout parameter does not seem to apply to the process of making the initial connection.

From the terminal, I run:

>>> import time >>> import requests >>> t1 = time.time() ; exec("try: requests.get('http://192.168.99.100/', timeout=1.0)\nexcept: pass") ; t2 = time.time() ; t2 - t1 21.00611114501953

This takes about 21 seconds and has no dependance on the timeout I give. I also tried using eventlet's timeout, but it turned out the same:

>>> import time >>> import eventlet >>> requests = eventlet.import_patched('requests') >>> t1 = time.time() ; exec("try: \n with eventlet.Timeout(1): requests.get('http://192.168.99.100/')\nexcept: pass") ; t2 = time.time() ; t2 - t1 21.00276017189026

The error I am getting for the connection is:

ConnectionError: ('Connection aborted.', error(11, 'Resource temporarily unavailable'))

Finally, I am running python under the Windows Subsystem for Linux, which might be working with sockets differently.

First, remove stuff that shouldn't be there:

$str = preg_replace('/[^PDL\d-]/i', '', $str);

That gives you the following normalised results:

D456789-1 D456789-1 D456789-1ldlddld

Then, attempt to match the data you want:

if (preg_match('/^([PDL])(\d+-\d)/i', $str, $match)) { $code = $match[1]; $load = $match[2]; } else { // uh oh, something wrong with the format! }

I presume you want the strings instead of the numerical values, correct?

s = '' for j in range(30, 0, -1): s += "{}/{} + ".format(31-j, j) print s[:-2]

Read this documentation to get a grasp of it. Essentially, it's formatting the string, using the two pairs of curly braces as placeholders, and passing in the value 31-j in the first slot, and j in the second.

Surely there is a more elegant way to do it, but this is the quick and dirty method.

It's actually not so hard to get this to work. It's a bit hacky since you are adding code to the engine's routes.rb file that changes depending on which env it's running in. If you are using the spec/dummy site approach for testing the engine then use the following code snippet in /config/routes.rb file:

# <your_engine>/config/routes.rb if Rails.env.test? && Rails.application.class.name.to_s == 'Dummy::Application' application = Rails.application else application = YourEngine::Engine end application.routes.draw do ... end

What this is basically doing is switching out your engine for the dummy app and writing the routes to it when in test mode.

There are better ways to solve your problem. The typical protocol I use is:

Register a window message using RegisterWindowMessage in both applications. The message name should contain a GUID to make it unique
In Application A, use
PostMessage(HWND_BROADCAST, registeredMsg, idIWantToFindYou, HWNDofA)
to publish your window handle to all top level windows. since there's more than one use for registered messages, and you should limit the number of messages you register, use idIWantTofindYou to distinguish between different commands for your message.
The receiving application(s) B now have the window handle of the sender, and can establish a connection (e.g. by
PostMessage(HWNDofA, registeredMessage, idHereIsMyHWnd, HWNDofB)

The upside of this mechanism is not running into problems with unresponsive programs. However, the "connection" isn't immediate, so you have to change your program flow. Alternatively, you can use EnumWindows and SendMessageTimeout to probe all top-level windows.

If you need to use the window class:

The class name assigned by MFC is only so window classes with the same attributes get reused. I am not aware of any problems with using your own window classes.

So the following should work:

Fill a WNDCLASS or WNDCLASSEX with the required attributes
Use DefWindowProc as WNDPROC (that's what MFC does, MFC's WNDPROC is set when creating the window)
Use AfxRegisterClass or RegisterClass to register the window class. AfxRegisterClass checks if the class is already registered and if the class is registered from a DLL, it will unregister the class when the DLL is unloaded. Otherwise they are roughly equivalent.

4353080 0 Testing on a single-core PC with hyperthreading

If a multithreaded program runs safe on a single-core CPU with hyperthreading, will it also run safe on a dual-core CPU with hyperthreading? Concerning thread-safety etc.

EDIT

Ok, I try to be more specific. I mean the bad source code lines, where I will have forgotten or failed to make sure, that they won't be an (concurrency) issue.

So, maybe the 1-core htt "lies" by preventing dead-locks, crashes, cpu spikes or anything that my code causes on a 2-core machine. I'm unsure, how exactly 2 (logical) processors of a htt PC are different from 2 processors of a dual-core PC, how transparent htt is. If there's any issue, I'll probably buy a second PC just for that, that's why I asked.

The class is being applied by the date picker plug-in, probably using the addClass function. The plug-in, when it's initialized, probably creates a DIV (id=;dp-popup') that has the necessary values for the current month. That DIV is hidden (display:none) but still has the class of dp-popup when first initialized. When you click in the textbox or click the button, there's an event handler assigned to those events (focus for the textbox, click for the button) that sets the display style of the DIV to not be hidden and it also positions it right below the text box.

I didn't dig into the code a whole lot, but looking at the markup a little, that's how I suspect it's working.

36123828 0 Double from CoreData returns very small number

I am working on a diving application, and one of the feature is to store diving's rating as double into CoreData. The interface should be able to retrieve the double value from the coredata object and then display on screen. However, the problem I got from my code is that the double returned from the object is very small (e with the power of -315). I have no idea why this is happening.

if let dives = self.diveSite?.logged_dives { for dive in dives { print("######### dive site info ########") rating = Double(dive.rating) + rating print(dive) print("raw dive site rating is \(dive.rating)") print("dive rating is \(rating)") } } else { print("no logged_dives") }

Here is what's been printed out on the console...

######### dive site info ######## <ScubaDoo.DiveLog: 0x7fe9ea02cbc0> (entity: DiveLog; id: 0xd000000000180002 <x-coredata://2B6F1E6F-1EDA-4910-91FA-0593E05F9EB2/DiveLog/p6> ; data: { current = nil; depth = 0; "dive_at" = "0xd000000000140000 <x-coredata://2B6F1E6F-1EDA-4910-91FA-0593E05F9EB2/DiveSite/p5>"; id = nil; latitude = 0; longitude = 0; rating = 5; "sea_condition" = nil; temperature = 0; time = nil; weather = nil; }) raw dive site rating is 5.35679601527854e-315 dive rating is 1.06203402623994e-314 dive site rating is 1.06203402623994e-314

The DiveLog object in swift is as below. I really do not have a clue about this. It seems that something is out of bound while getting the rating properties?

import Foundation import CoreData extension DiveLog { @NSManaged var time: NSDate? @NSManaged var latitude: NSNumber? @NSManaged var id: String? @NSManaged var rating: NSNumber? @NSManaged var depth: NSNumber? @NSManaged var temperature: NSNumber? @NSManaged var weather: String? @NSManaged var current: String? @NSManaged var sea_condition: String? @NSManaged var longitude: NSNumber? @NSManaged var dive_at: DiveSite? }

3309473 0 Spring-Hibernate used in a webapp,what are strategies for Thread safe session management

I'm developing a web app with Spring and Hibernate and I was so obsessed by making he application thread safe and being able to support heavy load that based on my boss recommendation I end up writing my own session and a session container to implement a session per request pattern. Plus I have a lot of DAOs and me not willing to write the same save method for all the DAOs I copy paste this Hibernate GenericDAO (I can't tell it's the same thing because at the time hibernate wasn't owned by jboss) and do the plumbing stuff, and under pressure, all become quickly complicated and on production, the is StaleObjectException and duplicated data right, and i have the feeling that it's time to review what I've done, simplify it and make it more robust for large data handling. One thing you should know is that one request involves many DAO's.

There is quartz running for some updates in the database.

As much as I want to tune everything for the better I lack time to do the necessary research plus Hibernate is kind of huge (learning).

So this is it, I'll like to borrow your experience and ask for few question to know what direction to take.

Question 1 : is Hibernate generated uuid safe enough for threading environment and avoiding StaleObjectException?

Question 2 what are best strategy to use hibernate getCurrentSession in threadSafe scenario (I've read about threadlocal stuff but didn't get too much understanding so didn't do it)

Question 3 : will HIbernateTemplate do for the simplest solution approach?

Question 4 : what will be your choice if you were to implement a connection pool and tuning requirement for production server?

Please do no hesitate to point me to blogs or resources online , all that I need is a approach that works for my scenario. your approach if you were to do this.

Another way to customize is as following:

columns: [ { command: [{ name: 'edit', click: editButtonClick, template: editButtonTemplate }], title: 'Edit', width: '40px'}..] var editButtonTemplate = '<a class="btn btn-link btn-xs k-grid-edit" href="\\#"><span class="glyphicon glyphicon-pencil"></span></a>'; editButtonClick = function (e) { /* Changes default rendering of 'update' & 'cancel' buttons * but keeps default behaviour */ var btnCancel = $('.k-grid-cancel'); btnCancel.removeClass('k-button k-button-icontext').addClass('btn btn-link btn-xs'); btnCancel.text(''); btnCancel.append('<span class="glyphicon glyphicon-ban-circle"></span>'); var btnOk = $('.k-grid-update'); btnOk.removeClass('k-button k-button-icontext k-primary').addClass('btn btn-link btn-xs'); btnOk.text(''); btnOk.append('<span class="glyphicon glyphicon-ok-circle k-update"></span>');

}

This approach handles click event of standard edit command and modifies rendered html, but preserves standard functionality.

Important detail - grid's update functionality is coupled to element with k-update attribute, while cancel functionality rides on k-grid-cancel.

The reason your initial attempt is not working is that you're attempting to capitalize a symbol or a string that represents the field name and not the actual variable.

You could do something like this and then the data would be capitalized before it's sent to the view.

@sexes = Sex.all.each{|sex| sex.name.capitalize}

When you say:-

var _db = new PortOfTroyCustomers.Models.PortOfTroyContext();

The compiler infers the type of the expression to the right of the assignment, this is known as implicit type in C#.

Now, you are trying to assign, your query like this, we have System.Data.Entity.DbSet on right & System.Linq.IQueryable on left which are different types:-

IQueryable<Accommodation> query = _db.Accommodations;

Thus, you need an explicit typecast like this:-

IQueryable<Accommodation> query = (IQueryable<Accommodation>)_db.Accommodations;

CATransaction works on Core Animation layer animations. CATransaction is cross-platform between iOS and Mac OS.

NSAnimationContext works with an NSAnimationContext. It's Mac OS specific.

(The NS animation stuff is Mac-only, and the UIView animation stuff is iOS only.)

I work in iOS more than Mac OS these days, and I always look for cross-platform ways to do things.

CAAnimation, CALayer, CAAnimationGroup, etc, are nearly identical between Mac and iOS. There are some differences (e.g. quicktime layers are not supported in iOS, Core Image support is more limited in iOS, etc.) but CA stuff is more alike than different.

36265049 1 Can't escape a while loop, Python 2.7

For some reason i can't escape while loop , i tried debugging it, and looks like for loop is untouched and i don't understand why. (it's fraction of mine tictactoe game code)

users_main = [] computers_main = [] while True: computers_storage = [] users_storage = [] if 0==0: condition = True while condition: guess_y = int(raw_input('Enter coordinate y:')) -1 guess_x = int(raw_input('Enter coordinate x:')) -1 users_storage.append(guess_y) users_storage.append(guess_x) users_main.append(users_storage) for a in computers_main: if a == users_storage: del users_storage[-2] del users_main[-1] condition = True break else: condition = False break break

23709460 0 When using the *sync functions in Node.js, what (if any) background operations continue to run

When using the Node.js *Sync functions (I understand you shouldn't, and the reasons why), what (if any) background processes continue to run?

For example, if I'm using http.createServer, and from one of the requests I call fs.writeFileSync(), will the server continue to serve new clients whilst that write is in progress (not just accept the connection, but process the entire request)? I.e. would writeFileSync() block the entire process, or just the current call chain?

This should do the trick:

#!/bin/bash for file in `find $1 -type f -name "*.txt"`; do nlines=`tail -n 1 $file | grep '^$' | wc -l` if [ $nlines -eq 1 ] then echo $file fi done;

Call it this way: ./script dir

E.g. ./script /home/user/Documents/ -> lists all text files in /home/user/Documents ending with \n.

If you want to totally throw it away:

import subprocess import os with open(os.devnull, 'w') as fp: cmd = subprocess.Popen(("[command]",), stdout=fp)

If you are using Python 2.5, you will need from __future__ import with_statement, or just don't use with.

To get the value of the "first" key, you can use it

map.get(map.keySet().toArray()[0]);

The solution for that problem seems to be this: you have to call the [player stop] before releasing it. It appears a little strange since I'm already receiving a notification about the player finished playing. Doing so the memory gets deallocated (only a small amount remains , ~100Kb from CoreMedia, but I believe is it normal

shmat() is a typical example of same physical address being mapped as two different virtual address in two different processes. If you do pmap -x pid_A . you will you see the virtual mem map for process A similarly for Process B. Actual Phy mem is not exposed to the user-space program.

Now SayProcess A and B share a shared memory segment and shared memory pointer be sh_mem_ptr_A and Sh_mem_ptr_B. If you print these pointers their address(virtual) will be different. Because Sh_mem_ptr_A is a part of memory map of Process A, Similarly sh_mem_ptr_B for Process B.

Kernel maintains the maaping of Virtual-to- phy addr. By page table and offset. Higher bits map to the page table and offset maps to offset in the page table. So If you notice the Lower order bits of sh_mem_ptr_A and sh_mem_ptr_B they will be same(but may not be true always).

Are you making multiple connection to your database without closing them? If you are you should try implementing a check to see if only one connection is up.

To check if your database is open you can do:

if(yourConnection.isOpen()){ doSomething(); //Maybe you want to close it here, if thats the case yourConnection.close(); }

Use django F() expression and update():

from django.db.models import F Model.objects.filter(condition=condition).update(field=F('field') * 1.5))

django doc about F() and update.

PS: Your model names are not following python class conventions. The should be capfirst with no underscores in between. Check pep8 doc for python class naming details.

Probably too late to be useful, but I was able to connect from Python 3.3 to a MySQL db on my Windows machine (!) using PyMySql (see https://code.google.com/p/pymysql/). Once installed, I used a variation on the code from your reference location here: Python 3 and mysql. I have a schema called "test" and a table called "users", here was the test code:

import pymysql conn = pymysql.connect(host='127.0.0.1', user='root', passwd='password', db='mysql') cur = conn.cursor() cur.execute("SELECT * FROM test.users") for r in cur: print(r) cur.close() conn.close()

If your target systems are managed by reasonable people, the software will be managed by the packaging system. On Redhat, Fedora, CentOS or SUSE systems that will be RPM. On any system derived from Debian it will be APT.

So your script can check for one of those two packaging systems. Although be warned that you can install RPM on a Debian system so the mere presence of RPM doesn't tell you the system type. Packages can also be named differently. For example, SUSE will name things a bit differently from Redhat.

So, use uname and/or /etc/issue to determine system type. Then you can look for a particular package version with rpm -q apache or dpkg-query -s postgresql.

If the systems are managed by lunatics, the software will be hand-built and installed in /opt or /usr/local or /home/nginx and versions will be unknown. In that case good luck.

An update on the last post... the code now includes a class for the list data structure. I've removed some bugs from the code. It should deliver the right results now.

It seems that for one dimensional data structures, a list structure can actually be faster that an array. But for two dimensional structures, as in the code below, arrays are substantially faster than lists, and significantly faster than dictionaries.

But it all depends on what you want to use the data structures for. For relatively small data sets, dictionaries and lists are often more convenient structures to use.

public interface IDataStructureTimeTestHandler { void PerformTimeTestsForDataStructures(); } public class DataStructureTimeTestHandler : IDataStructureTimeTestHandler { // Example of use: //IDataStructureTimeTestHandler iDataStructureTimeTestHandler = new DataStructureTimeTestHandler();

Since your parameters are named differently, not too big a deal to query for each one.

string ok = string.Empty; NavigationContext.QueryString.TryGetValue("ok", out ok); string ko = string.Empty; NavigationContext.QueryString.TryGetValue("ko", out ko);

Sometimes it helps to rephrase the problem: if I read you well, you don't want users, that have a deny time with at least one specified DayID/Hour/Minute:

where !i.UserDeniedTimes.Any( p => (p.AllowedDate.AllowedTimes.Any( a1 => a1.DayID == aTime.DayID && a1.Hour == aTime.Hour && a1.Minute == aTime.Minute )) )

This should select the users you want. If not, please tell in some more words what exactly you are trying to achieve.

If you used double quotes instead of single quotes it would work, but you'd be open to an injection attack if the variables weren't sanitized properly.

I found my way around it. I noticed it installs successfully globally. So I installed psycopg2 globally and created a new virtual environment with --system-site-packages option. Then I installed my other packages using the -I option.

Hope this helps someone else.

OK. I later found out that I had no gcc installed. So I had to install it first. And after that, I could pip install psycopg2. Thank you cel for the direction.

You need to know both, The RoR framework is an organizational and convenience system if you will, what it organizes is your ruby code.

You do not need globals for this. A simpler version might be something like:

Function mkArray() Const COLR_GREEN As Long = 11 Const COLR_RED As Long = 2 Dim areaArr As Variant, i As Long areaArr = ActiveSheet.Range("I1:J16").Value For i = 1 To UBound(areaArr, 1) Debug.Print areaArr(i, 1), areaArr(i, 2) Sheets("Sheet1").Shapes(areaArr(i, 1)).Fill.ForeColor.SchemeColor = _ IIf(areaArr(i, 2) > 500, COLR_GREEN, COLR_RED) Next i End Function

If you really want to split into separate subs then you should use parameters in place of globals:

E.g.

Function mkArray() Dim areaArr As Variant, i As Long areaArr = ActiveSheet.Range("I1:J16").Value For i = 1 To UBound(areaArr, 1) ColorShape Cstr(areaArr(i, 1)), areaArr(i, 2) Next i End Function Sub ColorShape(shpName as string, shpVal) Const COLR_GREEN As Long = 11 Const COLR_RED As Long = 2 Sheets("Sheet1").Shapes(shpName).Fill.ForeColor.SchemeColor = _ IIf(shpVal > 500, COLR_GREEN, COLR_RED) End Sub

32404260 0 Getting a 404 after starting Artifactory/Tomcat running on centos

I'm trying to get Artifactory running on a centos server. This is what I did:

Created a new user called artifactory

switched to that user

wget https://bintray.com/artifact/download/jfrog/artifactory-rpms/jfrog-artifactory-oss-4.0.2.rpm

then followed instructions from artifactorys docs

rpm -ivh jfrog-artifactory-oss-4.0.2.rpm

service artifactory start

service artifactory check

I get a pid, which according to docs. Everything is working properly. I then navigate to the webpage, but I get a 404:

HTTP Status 404 - /artifactory

type Status report

message /artifactory

description The requested resource is not available.

I want to check logs, which are apparently located at $ARTIFACTORY_HOME/logs/artifactory.log but dir is not found. Doing echo $ARTIFACTORY_HOME doesn't output anything. I did a find command on artifactory.log but no results. Super confused. Any tips would be appreciated.

Here are some log updates as per the tips from JBaruch.

35573235 1 Why some part of code is not participate in execution process

I am trying to split network into two groups (g1 and g2) according to the degree of nodes (if degree of node d>=691 then node is add in g1 otherwise node is add in g2)

35866392 0 My imagePickerController didFinishPickingMediaWithInfo newer get called

I try to write an App that needs a screen where you can take multible photos. I have used a code example from http://makeapppie.com/2015/11/04/how-to-make-xib-based-custom-uiimagepickercontroller-cameras-in-swift/.

It seems to be working OK, but my imagePickerController didFinishPickingMediaWithInfo newer get called. I am getting an error message from Xcode "Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates." It sounds to me like this could be the problem, and I have googled it, but havn't gotten any wiser. A lot of people write it's an Apple bug and I havn't found anybody offering a solution.

So do anybody know if it is the Xcode error that is my problem, and in that case have a solution for that or have I written something wrong in my code:

You would have to have the @interface and @implementation have the same class name. Aside from that, it does not matter what file the @interface or @implementation is in as long as the @interface is accessable from the file the @implementation is in (in the same file or #imported.

So in your case, if you did @interface ReceiverViewController... you would be fine.

One reason for using different tablespaces would be a desire to use tablespace transportation for moving data between databases. If you have a limited set of data that you want to move without having to export and import it then tablespace transport is a good option, particularly if it is important for testing reasons that the data have exactly the same physical structure as the source system (for performance analysis work, for example).

May be unrelated to performance, but the code as it written now has strange parallelization structure.

I doubt it can produce correct results, because the while loop inside the parallel does not have barriers (omp master does not have barrier, omp for nowait also does not have barrier).

As a result, (1) threads may start omp for loop before the master thread finishes Tree.PreProcessing(), some threads actually may execute omp for any number of times before the master works on single pre-processing step; (2) master may run Tree.PropagatePositions() before other threads finish the omp for; (3) different threads may run different time steps; (4) theoretically the master thread may finish all steps of the while loop before some thread even enters parallel region, and thus some iterations of the omp for loop may be never executed at all.

Or am I missing something?

10465242 0 ASP.Net/Ruby/PHP MVC Website, jQuery Mobile and Phonegap

I have an ASP.Net MVC3 application (it doesn't matter if it is ASP.NET MVC, PHP or RAILS coz in the end it is serving out plaing HTML) which is using jquery mobile and works great in all mobile browsers. The next step for me is to create a native ios app using Phonegap.

My guess is all I have to do is in the html page which I put in Phonegap, I will hook into page load event and dynamically load the contents of my MVC view from a remote server.

But I am looking for some examples if anyone else has done something similar.

-Thanks in advance Nick

UPDATE: I was able to accomplish this by writing the following index.html page. Hope it helps someone else.

STILL ISSUES THOUGH : But having done this...as you may notice I am requesting my ASP.NET MVC page via http://IP:8081 URL. This works fine and it loads my page too...but it is not jquery mobile formatted. So, if someone can help me out here, it will be great.

EXPLANATION : Since, the ajax.responseText contains the entire HTML starting from the <!DOCTYPE html> tag... I think it is pretty obvious that I end up inserting an entire HTML page inside my <div data-role="page" id="home"> tag which is obviously wrong but I don't have a solution for it yet :(

29423834 0 How to apply JSON data to an EmberJS Model Attribute

I'm very new to JS and I'm retrying EmberJS due to the impending 2.0 but especially because of EMBER CLI which I really like the structure.

Anyways, I'm building a basic app and what I'm currently looking to do is make a JSON call to reddit to grab the subscriber number and apply that number to a models subscriber number attribute. I'll also be cycling through an array of models too.

So for my instance, I've got models of lets say sports teams. Each team as a subreddit and when someone clicks the league they want, I'll be displaying all of the teams in that league.

I've got the the JSON working from a pure JS aspect, and I've got the Ember app working w/o any JSON. So I'm just trying to figure out how to connect the two while also realizing I will probably need to do some tear down to properly connect the two.

So my question is, how do I go about selecting a single piece of data from Reddit API to a single model attribute?

Here is the JS I'm using currently to pull the subscriber number.

$.each( teamList, function( key, val ) { $.getJSON( "http://api.reddit.com/r/"+val+"/about", function foo(data) { $("#team").append(val + " : "); $("#team").append(data.data.subscribers + '<br>'); } ); });

My current ember model setup is normal, but I am using fixtures since all data is static other than this model attribute.

The answer would be yes, assuming you consider this a good example of what you want to do:

This browser-based version of Asteroids was created using Pyjamas, which enables you to write the code in python in one place, and have it run either on the browser, or on the desktop:

http://pyjs.org/

Having recently found Pyjamas, and also preferring to consolidate my code in one language (Python!) and location (instead of having some code server-side, and some browser/client-side, in different languages), it's definitely an exciting technology. Its authors have ported the Google Web Toolkit to Python, a really impressive feat, retaining the expressive power of Python (something like 80,000 lines of Java was shrunk to 8,000 lines of Python). More Pythonistas should know about it. :)

if (preg_match('/\b\d{4}-\d{2}-\d{2}\b/' $str)) { // ... }

If the word boundary (\b) doesn't do the trick, you could try negative lookbehind and lookaheads:

if (preg_match('/(?<!\d)\d{4}-\d{2}-\d{2}(?!\d)/' $str)) { // ... }

As an additional validation, you could use checkdate() to weed out invalid dates such as 9999-02-31 as mentioned in this answer.

Query.Matches("story","<Regex for: moon or cow or Neil>");

Look here to see how to write a regex that matches multiple words. It's basically this:

^(?=.*\bmoon\b)(?=.*\bcow\b)(?=.*\bNeil\b)

In conclusion:

collection.Find(Query.Matches( "story", "^(?=.*\bmoon\b)(?=.*\bcow\b)(?=.*\bNeil\b)")) .SetSortOrder(SortBy.Descending("Submitted")).Skip(skip).Take(limit);

You can save popup window's text in webpart property in toolpart.

This property will be accessed in WebPart & ToolPart also.

For WebPart Properties see below example,

 [Personalizable(PersonalizationScope.Shared)] [WebBrowsable(true)] [Category("Display")] [WebDisplayName("Popup Text")] [Description("You can configure this text from here in popup")] public string PopupText { get; set; }

add above code in WebPart Class and use this "PopupText" property in assign Literal control OR direct render this property in overwrite Render method.

I guess you pass the wrong CGPoint coordinate to the hitTest:withEvent: method causing wrong behavior if the scroll view is scrolled.

The coordinate you pass to this method must be in the target views coordinate system. I guess your coordinate is in the UIScrollView's superview's coordinate system.

You can convert the coordinate prior to using it for the hit test using CGPoint hitPoint = [scrollView convertPoint:yourPoint fromView:scrollView.superview].

In your example you let the container view perform the hit testing, but the container can only see & hit the visible portion of the scroll view and thus your hit fails.

In order to hit subviews of the scroll view which are outside of the visible area you have to perform the hit test on the scroll view directly:

UIView *firstSubview = [_scrollView hitTest:number1RectanglePoint withEvent:nil]; UIView *fifthSubview = [_scrollView hitTest:number5RectanglePoint withEvent:nil];

It think you mean Sentinel nodes in a linked lists.

Some linked-list implementations put one or two extra nodes at the beginning and ending (or both of them) to implement some algorithms simpler. These nodes don't hold special data as a entry of data-structure. It's an alternative for usingNULL as first/last node indicators.

enter image description here

The std::list is supposed to be a list in the standards. It maybe uses sentinel nodes or not.

I did some of your work for you and found this date:duration function, which you seem to be trying to use. However, date:duration converts a number of seconds into a duration formatted string, whereas you want to find the difference (duration) between two datetime strings.

You probably want date:difference instead. If you read the documentation for this function/template, you'll find this about the arguments:

The two dates must both be right-truncated date/time strings in one of the formats defined in [XML Schema Part 2: Datatypes]. ... The permitted formats are as follows...
xs:dateTime (CCYY-MM-DDThh:mm:ss) ... 

There are italics there in the original: CCYY-MM-DDThh:mm:ss except the T is not italicized. In other words, the time strings need a literal T between the date and the time, whereas yours have a space.

So I would suggest fixing that:

<start>2011-12-13T16:15:26</start> <end>2011-12-13T16:17:27</end>

Pass the start and end strings as parameters to the template. You can do this by just passing the start and end element nodes, which will be automatically converted to strings based on their text content:

<xsl:variable name="time-diff-dur"> <xsl:call-template name="date:difference"> <xsl:with-param name="start" select="start" /> <xsl:with-param name="end" select="end" /> </xsl:call-template> </xsl:variable> <!-- The above returns a duration formatted string, so convert that to seconds: --> <xsl:variable name="time-diff-sec"> <xsl:call-template name="date:seconds"> <xsl:with-param name="seconds" select="$time-diff-dur" />? </xsl:call-template> </xsl:variable>

This code assumes that the context node is the parent of the <start> and <end> elements. After the above code, the variable $time-diff-sec will contain a result tree fragment, which can be converted to a number using number($time-diff-sec) if necessary.

Let us know whether that works. If not, state specifically what the result was and how it differs from what you expected.

Update:

I just noticed that you are using xsltproc (which uses libxslt). According to this documentation, libxslt supports date:difference (and date:seconds) natively. So you can call these functions as functions instead of defining a named template and calling it as a template. That would be a lot less code for you, albeit less portable:

<xsl:variable name="time-diff-sec" select="date:seconds(date:difference(start, end))" />

As before, you will need to declare the date namespace prefix somewhere, usually on your xsl:stylesheet element:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:date="http://exslt.org/dates-and-times" extension-element-prefixes="date">

3635013 0 Add a row to h:dataTable via AJAX with request-scoped bean without losing the row data

I think the title tells it all: I want to add a row to dataTable over AJAX. The datatable has input fields where user can put text. As simple as that, a pretty common case.

With session-scoped bean this no issue, as the same bean is updated over and over again. However, I want to do this in request scope. For each request, I guess I want to create a new bean and to populate it with the values from my form. Then I want my commandButton's action to add a new row, finally render the dataTable over AJAX as usual.

The issue is that I don't know how to make JSF fill the newly-created request-bean with the current data from the dataTable component?

There was a similar question asked and answered. However, that solution seems to reload the contents of the dataTable each time it is refreshed and manually inserts empty elements for the newly-inserted rows like this:

// Preserve list with newly added items. ror (int i = 0; i < (Integer) count.getValue(); i++) { list.add(new Item()); }

To me, it seems that this approach also wipes the possible changes that the user did to rows (new and old)... if he doesn't first save them.

Any pointers?

The scope of count is just the single child you are processing. Move it to a higher scope:

$(xml).find('parent').each(function () { var body = $('body').addClass('nobg'); var count = 1; $(xml).find('child').each(function() { if ($(this).attr('title') > '') { var title = $('<p></p>').appendTo(body); headline.attr('id'), (count++)); } }) })

Also, to be on the safe side, I would replace count++ with ++count as you need it to increment before it is used. This is pure readability, though, in your case.

My vote would be for XStream. The lack of generics support is a small price to pay for the amount of flexibility it offers. You can also easily implement generics by serializing the generic class type at serialization time, or build this into your domain objects. E.g.

 class Customer { List<Order> orders; public List<Order> getOrders() { return orders; } }

In the stream, the element type denotes the type of each object. When the type is an abstract type or interface, the element listed with the implementing class, unless that has been specified as the default for that interface type. (E.g. ArrayList as the default for instances of static type List.)

Generics are "rose coloured glasses" in java - they don't really change what you are seeing, just how you see it. The objects would be sent over the wire exactly the same if they were sent with generics support or not.

Is there an error of some sorts, or you just don't understand how that works?

navigator.webkitGetUserMedia expects 3 arguments. One for configuration data, one for a function to call on success (a success callback) and one to call on error.

Note that it expects a function. This code passes a reference to the function by name; it will be called with the appropriate parameter (from within webkitGetUserMedia).

Consider this code, it works in the same manner:

List D has the values 2, 5, 6

In this situation I only want List C, since this is the only list which contains the values 1, 2 end 3.

I've tried this, but this doesn't work since it is always true:

query = from doc in query let tagIds = from t in doc.Tags select t.Id where parameters.TagIds.Except(tagIds).Count() <= parameters.TagIds.Count() select doc;

And when using this:

 query = from doc in query let tagIds = from t in doc.Tags select t.Id where !parameters.TagIds.Except(tagIds).Any<int>() select doc;

I only get the lists where the list matches exactly the 'required' list.

CREATE TABLE v (`id` int, `lat` int, `lng` int, `l` varchar(3), `name` varchar(8)) ; INSERT INTO v (`id`, `lat`, `lng`, `l`, `name`) VALUES ( 1, 12, 12, 'a', 'group1-1'), ( 2, 12, 12, 'b', 'group1-2'), ( 3, 13, 12, 'c', 'single1'), ( 4, 13, 13, 'd', 'group2-1'), ( 5, 13, 13, 'e', 'group2-2'), ( 6, 13, 13, 'f', 'group2-3'), ( 7, 10, 13, 'g', 'group3-1'), ( 8, 10, 13, 'h', 'group3-2'), ( 9, 11, 12, 'h', 'group4-1'), (10, 11, 12, 'h', 'group4-2'), (11, 10, 14, 'i', 'group5-1'), (12, 10, 14, 'j', 'group5-2'), (13, 10, 14, 'j', 'group5-3') ;

Now I want to get all rows where there is more than one row with the same lat and lng values (let's call that a group):

SELECT v.* FROM v INNER JOIN ( SELECT lat, lng FROM v GROUP BY lat, lng HAVING COUNT(*) > 1 ) AS vg USING (lat, lng) ORDER BY name ;

Outputs:

ID LAT LNG L NAME 1 12 12 a group1-1 2 12 12 b group1-2 4 13 13 d group2-1 5 13 13 e group2-2 6 13 13 f group2-3 7 10 13 g group3-1 8 10 13 h group3-2 9 11 12 h group4-1 10 11 12 h group4-2 11 10 14 i group5-1 12 10 14 j group5-2 13 10 14 j group5-3

Works well so far, all but the "single1" rows are selected and ordered by group.

Now I want to add a limit to form different pages of this data. But all rows of the same group need to be on the same page (but not one page per group and it doesn't matter how many rows actually are on one page - just not too many). I don't see this done with a LIMIT statement, so I started to write my own:

SET @grp := 0, @last_lat := '', @last_lng := ''; SELECT * FROM ( SELECT v.*, @grp := IF((@last_lat = lat) && (@last_lng = lng), @grp, @grp + 1) AS grp, @last_lat := lat AS llat, @last_lng := lng AS llng FROM v INNER JOIN ( SELECT lat, lng FROM v GROUP BY lat, lng HAVING COUNT(*) > 1 ) AS vg USING (lat, lng) ORDER BY lat, lng ) AS vv WHERE grp BETWEEN 0 AND 7 ORDER BY grp ;

This query whit out the WHERE part outputs this data:

ID LAT LNG L NAME GRP LLAT LLNG 1 12 12 a group1-1 6 12 12 2 12 12 b group1-2 6 12 12 5 13 13 e group2-2 7 13 13 6 13 13 f group2-3 7 13 13 4 13 13 d group2-1 7 13 13 7 10 13 g group3-1 8 10 13 8 10 13 h group3-2 8 10 13 10 11 12 h group4-2 9 11 12 9 11 12 h group4-1 9 11 12 13 10 14 j group5-3 10 10 14 11 10 14 i group5-1 10 10 14 12 10 14 j group5-2 10 10 14

The idea is to change the values in the line WHERE grp BETWEEN 0 AND 7 for each page. But the numbers from the group don't start at 1 and I can't see why (and that makes it unusable for the first page). The Start number is different depending on how many group are in the whole data. So what I need to have, is that the grp column start whit 1 and then continues whit always +1.

What is wrong with this query and are there any better ways to do this?

You can play whit this query here: http://sqlfiddle.com/#!8/86d3c/2

Using one floated span with a border:

<div class="heading"> <span></span> <h3>Heading<h3> </div> .heading { width: 100%; text-align: center; line-height: 100%; } .heading span { float: left; margin: 20px 0 -8px; border: 1px solid; width: 100%; } .heading h3 { display: inline; padding: 0px 0px 0 20px; width: auto; margin: auto; }

The negative base margin on the span may need to be adjusted for different heading sizes. , The background colour of the heading should match the background of the overall container.

You should move the time logic into your database query - there's no point in fetching ALL rows, only to throw away some (most? all?) of the rows if there's nothing to do:

SELECT * FROM users WHERE `time` < (now() - INTERVAL 3 DAY)

Once that's done, I'd suggest moving the actual mail() portion out of the database fetching loop, so that you can batch together each user's brochures first:

$users = array(); while($row = mysql_fetch_array($time_query_result)) { if (!array_key_exists($row['userID'], $users)) { $users[$row['userID']] = array('email' => $row['email'], 'brochures' => array()); $users[$row['userID']]['brochures'] = array('b' => $row['brochures'], 't' => $row['time']); } }

You'd then loop over this $users array to build emails for the users:

foreach ($users as $user) { $text = '<html><body><p>Brochure reminder</p>'; $i = 1; foreach ($user['brochures'] as $brochure) { $text .= 'Brochures:<br />'.$i++ .$row['b']. $row['b']; } $text .= '</body></html>'; mail($user['email'], $subject, $text, $headers); }

This way, you fetch all the user details in one go. You then build a SINGLE email to each user, listing all of their brochures, and (hopefully) problem solved.

Minimax with Alpha-beta pruning that Lirik mentioned is a good place to start, but it takes some time to wrap your mind around if you're not familiar with it.

Alternatively you can think about how you would play the game if you had a perfect memory and could do fast calculations and try to implement that. The upside is that's usually easier to understand.

Minimax would probably result in shorter but more difficult to understand (for those unfamiliar with it) code that depending on the game, could result in playing a perfect game if the game is simple enough (however it also has the disadvantage of favoring not losing to winning because it assumes the opponent will be playing perfectly as well)

Since it sounds like it's a game of complete information (the whole board is visible to all players at all times) a properly implemented Minimax with infinite look-ahead could give an AI that would never lose (assuming infinite computation time). In games using Minimax the difficulty level is often determined by how many moves ahead the algorithm looks at. It gets exponentially slower the more steps there are, so you will run into a hardware limitation if the game isn't super simple (which is why there isn't a perfect Chess playing AI yet, I think last I checked it would take a couple thousand years on the fastest computer at the time of the article I read, sorry no citations)

I am trying to handle InvalidArgumentException in a custom way. In app/start/global.php I have the following code block after the built in App::error(Exception $exception... block:

App::error(function(InvalidArgumentException $exception, $code){ // die('last'); $exceptionData['exception'] = $exception; $exceptionData['code'] = $code; ExceptionNotificationHandlerController::notify($exceptionData); });

die()ing, breakpoints, etc all suggest to me that it never goes into that block of code when I throw an InvalidArgumentException. Help?

You could add one event handler for each container you actually want to receive the event in (if this is feasable in your setup):

(somewhere:)

(function() { var container = document.getElementById('mainwrap'); container.addEventListener('click',handler,false); function handler(e) { e = e || window.event; var element = e.target || e.srcElement; console.log("Element actually clicked: ", element); console.log("Container receiving event: ", container); } })();

Or expand to (can register handler for multiple containers..):

function registerHandlerForContainer(container_id, handler) { var container = document.getElementById(container_id); container.addEventListener('click',delegating_handler,false); function delegating_handler(e) { handler(container, e); } } function handler(container, e) { e = e || window.event; var element = e.target || e.srcElement; console.log("Element actually clicked: ", element); console.log("Container receiving event: ", container); } registerHandlerForContainer('mainwrap', handler);

17145193 0 How to let a specific android device (fonepad) use different layout folder

I'm working on an Android app that has different layouts for phones (designed for portrait) and for tablets (designed for landscape).

Now I want to support the Asus Fonepad as a phone but since it has the size and resolution of a 7 inch tablet it always uses the layouts in the layout-sw600dp folder. But the fonepad understands itself as a phone and shows the fullscreen text edit window whenever text input is used in landscape.

How can I make this device use layouts and values from the phones and not from the -sw600dp folders? Is this even possible?

Answering question 2, with pandas 0.18.0 you can do:

store = pd.HDFStore('compiled_measurements.h5') for filepath in file_iterator: raw = pd.read_csv(filepath) store.append('measurements', raw, index=False) store.create_table_index('measurements', columns=['a', 'b', 'c'], optlevel=9, kind='full') store.close()

Based on this part of the docs.

Depending on how much data you have, the index creation can consume enormous amounts of memory. The PyTables docs describes the values of optlevel.

Use EXPLAIN to see how MySQL handles the queries, it might give you a clue.

Also, try some other characters. Maybe MySQL is misinterpreting one of those as having a percent sign in it.

In standard css this would be:

button button

But you have to be careful on other pages it can also select 3rd, 4th and so on.

That is to say, there is no ordinality in standard css - only classes and id's and their hierarchy level (parent/child) relationships, unlike xpath.

You are appending the same class : color-9999CC to all your rect elements, so once you hover the last legend item having color : #9999CC all rect element will be selected.

To create the required class properly, you can add the corresponding color info to each element in your layers object while creating it.

I added a color property that has as value the color of the corresponding headers item:

var layers = d3.layout.stack()( headers.map(function (count) { return fData.map(function (d,i) { return { x: d.orders, y: +d[count] , color: colorScale(count)}; /*color = current headers item color */ }); }));

Then while creating your rect items you can add to each element a class by accessing its color property like this:

var rect = layer.selectAll("rect") .data(function (d) { return d; }) ..... .attr("class", function (d) { return "rect bordered " + "color-" +d.color.substring(1); });

complete code:

var margin = {top:10, right: 10, bottom: 80, left: 50}, width =960, height=650; var svg = d3.select("body") .append("svg") .attr("width", width + margin.left + margin.right) .attr("height", height + margin.top + margin.bottom) .append("g") .attr("transform", "translate(" + margin.left + "," + margin.top + ")");

According to the Molliza Developer Network documentation:

The HTML <meta> element represents any metadata information that cannot be represented by one of the other HTML meta-related elements (<base>, <link>, <script>, <style> or <title>).

Charset (Character set) is a set of encodings used to represent characters to the screen. UTF-8 is a specific type capable of encoding all possible characters, or code points, in Unicode.

Q: In the above code what is the meaning of <meta charset="utf-8"/>?

Adding this attribute declares, but don't guarantee the character encoding used for that specific web document.

Q: If i remove it from the code, there is no error.

Remember when I said there was no guarantee in the previous sentence? This is because the <meta ..> tag is only part of the algorithm that browsers use to apply. Again, referencing the mozilla docs, The HTTP Content-Type header and any BOM elements have precedence over this element. For a more comprehensive understanding, see whatwg.org.

You may ask then what is the point of implementing that line at all if the browser can perform shallow reasoning to include the charset encoding by default. The answer is simple:

More assertive programming.
Better practice.
The browser may get it wrong.
Prevents IE guessing it is encoded in UTF-7.

12188339 0 Java write to Stdin

So I have imported a jruby interpreter as a library to run an external ruby application. However I need to interact with the ruby application in some way. Right now I have the ruby application outputting information on stdout and requesting user options in stdin.

So if I want java to be able to handle inserting the options instead of a user, I'll need a way that I can write to the stdin somehow from java to choose the options. Does anyone know how I can do this? Or even a better way to do this?

I'm calling jruby like so:

String[] newargs = new String[2]; newargs[0] = "-S"; newargs[1] = "path_to_some_rubyfile.rb" org.jruby.Main jruby = new org.jruby.Main(); ruby.main(newargs);

The ruby app outputs stuff like this:

How do you feel today? (1) Happy (2) Sad

And then waits for the user input to enter 1 or 2. But I would like Java to input these options instead of having a user do it.

I am developing a flash based website using mxml. My monitor's resolution is 1280x768 and is widescreen. The problem is while it appears properly in my screen it doesn't appear properly in others. Which is the best approach to solve the problem ?

I have 2 in mind.

Let scrollbars take care of it : If the screen is 14 inch screen with 800x600 resolution it appears zoomed in. So thats a problem

Get screen resolution and resize using scaleX and scaleY : The graphic components will get resized but fonts give problem.

Which is the best approach among these ? If there is a better approach please mention. Thanks

Unless you are doing something really special with it, you should not directly read the app.config file, but use ConfigurationManager class to read from it. If you really want to read it as XML, use XmlDocumen.Load() function, but plaease keep in mind that parsing config as an XML file is an unintended way of use.

Install the New Relic Standard addon - that will give you insight into your application and what's going on. The 'Dynos' tab will show you memory utilisation of your application, it sounds like an awfully high memory utilisation for the level of traffic you're reporting but it depends on your application - if you're seeing memory errors in the log then performance will be suffering see http://devcenter.heroku.com/articles/error-codes#r14__memory_quota_exceeded

Are you using any kind of error handling? You could install the Airbrake addon so you get notification of errors or use the Exception Notifier gem which will email you errors as they occur. Once you have these in place you'll know what's occuring - whether it's in the application or if you don't receive any then it's outside factors, like the visitors internet connection etc.

Memory Layout of C Programs

A typical memory representation of C program consists of following sections.

Text segment

Initialized data segment

Uninitialized data segment

Stack

Heap

And a C statement like const char* string = "hello world" makes the string literal "hello world" to be stored in initialized read-only area and the character pointer variable string in initialized read-write area.

You cannot get the data from grid for searching, you need to store you data some where for using search. That is to store in a ViewState, Session or call DataBase on every search. Bellow code show data stored in a ViewState, you can acces your data any time by just using GridViewData where you can done search. (if you have very large amount of data first preference is calling data from database on every search.)

protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { GridView1.DataSource = GridViewData; GridView1.DataBind(); } } public DataSet GridViewData { get { if (ViewState["GridViewData"] == null) { String str = "select * from tblEmployee where (Name like '%' + @search + '%')"; SqlCommand xp = new SqlCommand(str, objsqlconn); xp.Parameters.Add("@search", SqlDbType.NVarChar).Value = TextBox1.Text; objsqlconn.Open(); xp.ExecuteNonQuery(); SqlDataAdapter da = new SqlDataAdapter(); da.SelectCommand = xp; DataSet ds = new DataSet(); da.Fill(ds, "Name"); objsqlconn.Close(); ViewState["GridViewData"] = ds; } return (DataSet)ViewState["GridViewData"]; } }

Rather than keeping a list of all the swaps you do as they are performed, compare your starting and finishing data at the end of the day, and then generate the swaps you would need to make that change. This would ignore any locations in the list that remain unchanged, even if they are only unchanged because a series of swaps "undid" some change. If you have your data take the form of a,b,a,b,... where a tells you the index of the next elements to leave in the same order they're in, and b tells you the index of the item to swap it with.

Because you're only doing swaps instead of shifts, you should very rarely end up with data like your sample data where 30, 40, and 50 are in the same order but in a slightly different location. Since the number of swaps will be between 1/4 and 1/10 the number of original items in the list, you'll usually have a big chunk of your data in both the same order and the same location it was in originally. Let's assume the following swaps were made:

1 <-> 9 4 <-> 2 5 <-> 2

The resulting list would be:

 1. 90 2. 50 3. 30 4. 20 5. 40 6. 60 7. 70 8. 80 9. 10

So the change data could be represented as:

 1,9,2,4,4,5

That's only six values, which could be represented as 16-bit numbers (assuming you won't have over 16,000 items in your initial list). So each "effective" swap could be represented with a single 32-bit number. And since the number of actual swaps will generally be 1/5 to 1/2 the size of the original list, you'll end up sending between 10% and 20% of the data in your original list over the wire (or less since the number of "effective" swaps may be even less if some of those swaps undo one another).

20962068 0 Create a name system to html Id attibute so they do not repeat

I'm not sure if I make sense, maybe there are easier ways.

I am building a web app, which will be based in Bootstrap models, what I want is to display a model to make CRUD operations to my database.

For example I will have a models like these:

public class Author { public int id { get; set; } public string Name { get; set; } } public class Book { public int id { get; set; } public string Name { get; set; } }

What I want is to make a partial view that will display a dialog (modal) to add a new author to my app, same with books, and my 'n' classes my app will have, I want to render these partials wherever I need them. So I can add an author from any view of my page.

That part is ok, now I am having some 'troubles' because when I make an ajax post call to save my author in my data base I am facing that I already had a #Name field which was the one rendered for my books modal now when I call my field with jQuery, like this: $('#Name').val() it will grab the first #name.

That is easy to solve I will make a #AuthorName and a #BookName.

Now I am scared that my application will not be stable if my name system is not.

So is there any way to make an name system?

I am not sure how to do this but I would like to write my id's like this:

 @Html.TextBoxFor(u => u.Id, new { @id = "@MyDialogs.Authors.Add.Name" })

that will return something like this: dialogs-authors-add-namefield

Is this possible or I am being too lazy?

Try this:

$title = explode('-', $title, 2); $title = trim($title[1]);

First you split the title in the two parts, than you keep only the last one removing all extra whitespaces.

If you have at least PHP 5.4, you could do

$title = trim(explode('-', $title, 2)[1]);

Although your device is capable of satisfying the usesdevice allocation, without a GPP or other ExecutableDevice, there is no place to run your component. There are two ways that allocation is performed when launching components:

Satisfying usesdevice relationships
Deciding on which device to deploy the executable

Each implementation in the component's SPD has a list of dependencies that must be satisfied to run the entry point. Typically, for a C++ component, this will include the OS and processor type. Additional requirements can be defined based on the processing requirements of the component, such as memory or load average; these must be allocation properties known to the target device, just like with usesdevice. There is also an implicit requirement that the device selected for deployment should support the ExecutableDevice interface (there is slightly more nuance to it, but that's by far the most common case).

When launching a waveform, the ApplicationFactory tries to allocate all required devices and select an implementation for each component in sequence. Each possible implementation is checked against all of the devices in the domain to see if there is a device that meets its dependencies. If so, the entry point for that implementation will be loaded onto the device and executed, and the ApplicationFactory moves on to the next component. If no suitable device can be found, it throws a CreateApplicationError, as you are seeing.

For most cases, you can use the GPP device included with REDHAWK to support the execution of your components. You would usually only write your own ExecutableDevice if you have a specific type of hardware that does not work with GPP, like an FPGA. If you have installed from RPM, there should be a node tailored to your local system (e.g., processor type, Java and Python versions) in your $SDRROOT/dev/nodes directory. Otherwise you can create it yourself with the 'nodeconfig.py' script included with the GPP project; see the Ubuntu installation guide for an example (admittedly, somewhat buried in the REDHAWK Manual, Appendix E, Section 5).

You can use either, but fabric.api is specifically the better option. This is because it's where the other fabric modules are imported for simplicity's sake. See here:

$ cat fabric/api.py (env: selenium) """ Non-init module for doing convenient * imports from. Necessary because if we did this in __init__, one would be unable to import anything else inside the package -- like, say, the version number used in setup.py -- without triggering loads of most of the code. Which doesn't work so well when you're using setup.py to install e.g. ssh! """ from fabric.context_managers import (cd, hide, settings, show, path, prefix, lcd, quiet, warn_only, remote_tunnel, shell_env) from fabric.decorators import (hosts, roles, runs_once, with_settings, task, serial, parallel) from fabric.operations import (require, prompt, put, get, run, sudo, local, reboot, open_shell) from fabric.state import env, output from fabric.utils import abort, warn, puts, fastprint from fabric.tasks import execute

fabric.api is importing fabric.operations.reboot for you already.

25540407 0 Summarize a list of Haskell records

Let's say I have a list of records, and I want to summarize it by taking the median. More concretely, say I have

data Location = Location { x :: Double, y :: Double }

I have a list of measurements, and I want to summarize it into a median Location, so something like:

Location (median (map x measurements)) (median (map y measurements))

That is fine, but what if I have something more nested, such as:

data CampusLocation = CampusLocation { firstBuilding :: Location ,secondBuilding :: Location }

I have a list of CampusLocations and I want a summary CampusLocation, where the median is applied recursively to all fields.

What is the cleanest way to do this in Haskell? Lenses? Uniplate?

Edit: Bonus:

What if instead of a record containing fields we want to summarize, we had an implicit list instead? For example:

data ComplexCampus = ComplexCampus { buildings :: [Location] }

How can we summarize a [ComplexCampus] into a ComplexCampus, assuming that each of the buildings is the same length?

You must use string formatting to substitute variable for its value

cursor.execute("UPDATE `ISEF_DB`.`attendance` SET `present`='1' WHERE `id` = '%s'" % data)

Although be warned that this leaves you susceptible to SQL Injection. To prevent that you can use exceute like so (from the docs)

cursor.execute("UPDATE `ISEF_DB`.`attendance` SET `present`='1' WHERE `id` = '%s'", (data,))

i.e. pass the values as tuples to execute. More information about avoiding SQL injection when using MySQLDB can be found in this question

with chai-as-promised

Here's how you can use chai-as-promised to test both resolve and reject cases for a Promise:

var chai = require('chai'); var expect = chai.expect; var chaiAsPromised = require("chai-as-promised"); chai.use(chaiAsPromised); ... it('resolves as promised', function() { return expect(Promise.resolve('woof')).to.eventually.equal('woof'); }); it('rejects as promised', function() { return expect(Promise.reject('caw')).to.be.rejectedWith('caw'); });

without chai-as-promised

You can accomplish the same without chai-as-promised like this:

it('resolves as promised', function() { return Promise.resolve("woof") .then(function(m) { expect(m).to.equal('woof'); }) .catch(function(m) { throw new Error('was not supposed to fail'); }) ; }); it('rejects as promised', function() { return Promise.reject("caw") .then(function(m) { throw new Error('was not supposed to succeed'); }) .catch(function(m) { expect(m).to.equal('caw'); }) ; });

Well according to the Lua documentation on the require call (using Lua 5.2 here), there are a few places the loader looks for these loadable modules.

It seems that require() uses what are called "searchers" (docs linked to in above) to determine where to find these modules. There are four searchers in total. From the docs:

The first searcher simply looks for a loader in the package.preload table.

The second searcher looks for a loader as a Lua library, using the path stored at package.path. The search is done as described in function package.searchpath.

The third searcher looks for a loader as a C library, using the path given by the variable package.cpath. Again, the search is done as described in function package.searchpath. For instance, if the C path is the string "./?.so;./?.dll;/usr/local/?/init.so" the searcher for module foo will try to open the files ./foo.so, ./foo.dll, and /usr/local/foo/init.so, in that order. Once it finds a C library, this searcher first uses a dynamic link facility to link the application with the library. Then it tries to find a C function inside the library to be used as the loader. The name of this C function is the string "luaopen_" concatenated with a copy of the module name where each dot is replaced by an underscore. Moreover, if the module name has a hyphen, its prefix up to (and including) the first hyphen is removed. For instance, if the module name is a.v1-b.c, the function name will be luaopen_b_c.

The fourth searcher tries an all-in-one loader. It searches the C path for a library for the root name of the given module. For instance, when requiring a.b.c, it will search for a C library for a. If found, it looks into it for an open function for the submodule; in our example, that would be luaopen_a_b_c. With this facility, a package can pack several C submodules into one single library, with each submodule keeping its original open function.

The searcher of use to us is the third one: it is used for any shared libraries (.dll or .so) which is generally how our custom C modules are built.

Using the template string (the one with the question marks), the searcher will look in each of the specified paths, substituting the argument of require() in place of the question mark. In order to specify the path for this third searcher, one must set (or append to) package.cpath and then call require().

So perhaps you have a directory structure as

- ROOT |-lua |-bin

where lua contains script.lua and bin contains mylib.so

To load mylib.so, you just need these two lines of code in script.lua:

package.cpath = '/ROOT/bin/?.so;' .. package.cpath libfuncs = require('mylib')

NOTE: Notice the semicolon. If you append (as opposed to the prepending above), make sure to lead with the semicolon on your added path. It is not there buy default. Otherwise your new path will be merged to the current default cpath, which is just ./?.so.

As you can see I prepared for simplicity a test method in Home controller. If I call http://xx.xx.xxx.107/index.php/Home/test I get the same log sequence and it shows the home view instead of printing my raw data.

It seems that as it is not able to get correct URi, it run default controller.

double[] array is object. So, you get address and entire array is added at index 0.

You may use Arrays.toString(x.get(0)) to get readable array print.

toString() for an array is to print [, followed by a character representing the data type of the array's elements, followed by @ then the memory address.

If you're using Java, you may want to check out Sikuli-API instead. It tries to be more of a standard Java library.

Sikuli-API uses SLF4J, so you just connect it to whatever logging framework you use (I like Logback a lot), and it will use that configuration.

2557207 0 Selectively replacing words outside of tags using regular expressions in PHP?

I have a paragraph of text and i want to replace some words using PHP (preg_replace). Here's a sample piece of text:

This lesson addresses rhyming [one]words and ways[/one] that students may learn to identify these words. Topics include learning that rhyming words sound alike and these sounds all come from the [two]ending of the words[/two]. This can be accomplished by having students repeat sets of rhyming words so that they can say them and hear them. The students will also participate in a variety of rhyming word activities. In order to demonstrate mastery the students will listen to [three]sets of words[/three] and tell the teacher if the words rhyme or not.

If you notice there are many occurances of the word 'words'. I want to replace all the occurances that don't occur inside any of the tags with the word 'birds'. So it looks like this:

This lesson addresses rhyming [one]words and ways[/one] that students may learn to identify these birds. Topics include learning that rhyming birds sound alike and these sounds all come from the [two]ending of the words[/two]. This can be accomplished by having students repeat sets of rhyming birds so that they can say them and hear them. The students will also participate in a variety of rhyming word activities. In order to demonstrate mastery the students will listen to [three]sets of words[/three] and tell the teacher if the birds rhyme or not.

Sure. You can use the magic constant __FILE__ which contains the path to the file that you use it in:

class MyClass def initialize puts File.read(__FILE__) end end

This will print the contents of the file containing the definition of MyClass every time you create a MyClass object.

26057790 0 Redis key not removed even after Resque job completes successfully

Here is my scenario, i'm using resque to queue a job in redis, the usual way its done in ROR. The format of my key looks something like this (as per my namespace convention)

"resque:lock:Jobs::XYZ::SomeCreator-{:my_ids=>[101]}"

The job runs successfully to completition. But the key still exists in redis. For a certain flow, i need to queue and execute the job again for the same parameters (the key will essentially be same). But seems like the job does not get queued.

My guess is that since the key already exists in Redis, it does not queue the job again.

Questions:

Is this behavior of resque normal (not removing the key after successful completition)?

If Yes, how should i tackle this scenario (as per best practices)?

If No, can you help me understand what is going wrong?

I believe there are three different concepts: initializing the variable, the location of the variable in memory, the time the variable is initialized.

First: Initialization

When a variable is allocated in memory, typical processors leave the memory untouched, so the variable will have the same value that somebody else stored earlier. For security, some compilers add the extra code to initialize all variables they allocate to zero. I think this is what you mean by "Zero Initialization". It happens when you say:

 int i; // not all compilers set this to zero

However if you say to the compiler:

 int i = 10;

then the compiler instructs the processor to put 10 in the memory rather than leaving it with old values or setting it to zero. I think this is what you mean by "Static Initialization".

Finally, you could say this:

 int i; ... ... i = 11;

then the processor "zero initializes" (or leaves the old value) when executing int i; then when it reaches the line i = 11 it "dynamically initializes" the variable to 11 (which can happen very long after the first initialization.

Second: Location of the variable

There are: stack-based variables (sometimes called static variables), and memory-heap variables (sometimes called dynamic variables).

Variables can be created in the stack segment using this:

int i;

or the memory heap like this:

int *i = new int;

The difference is that the stack segment variable is lost after exiting the function call, while memory-heap variables are left until you say delete i;. You can read an Assembly-language book to understand the difference better.

Third: The time the variable is initialized

A stack-segment variable is "zero-initialized" or statically-initialized" when you enter the function call they are defined within.

A memory-heap variable is "zero-initialized" or statically-initialized" when it is first created by the new operator.

Final Remark

You can think about static int i; as a global variable with a scope limited to the function it is defined in. I think the confusion about static int i; comes because static hear mean another thing (it is not destroyed when you exit the routine, so it retains its value). I am not sure, but I think the trick used for static int i; is to put it in the stack of main() which means it is not destroyed until you exit the whole program (so it retains the first initialization), or it could be that it is stored in the data segment of the application.

From your MainActivity:

Intent intent = new Intent(this, mySensor.class); intent.putExtra("type", Sensor.TYPE_LIGHT);

and within your service:

@Override public IBinder onBind(Intent intent) { mSensorManager= (SensorManager) getSystemService(Context.SENSOR_SERVICE); int type = intent.getExtras().get("type"); s= mSensorManager.getDefaultSensor(type); return null; }

then you can remove:

public mySensor(int type){ ... }

and eventually the code you wrote within the onCreate.

39275662 0 Google not crawling my pages even using history.pushState()

I read a lot on SEO compatibility with google crawler before starting my new project. And everything tends to say that Google know execute javascript, and so can render my template. For example here.

But it seems that the crawler never execute my javascript, and the templating with some api's data isn't done. (I seen that after using the "fetch as google tool")

I started my router like this

Backbone.history.start({pushState: true, hashChange: false});

And so route are handled like this:

Backbone.history.navigate(url, { trigger: true });

So I probably miss something somewhere but where ?

browserify needs an absolute path to retrieve the file and it leaves that as the bundle key. The way to fix it is to use the expose option...

In your build..

var dependencies = [ 'lodash', {file: './test.js', expose: 'test'}, ];

var _ = require('lodash'); var test = require('test');

You are hiding your adMobBannerView in your displayiAdsOrNot function. This function is called every time the viewWillAppear. Remove this and you should get the results you desire.

As for the rest of your code, you have a lot going on here. First, to simplify things you should move all of your code that is creating and laying out your adBanner and adMobBannerView under viewWillAppear when [[NSUserDefaults standardUserDefaults] boolForKey:@"IAPSuccessful"] is false, and set both banners .hidden = YES automatically. This will eliminate the need for your displayiAdsOrNot and displayAdMobBannerOrNot where you are repeating a lot of the same if statements checking for IAP and which device the user is using. After doing this, in your delegate methods you can simply hide or show the correct banner depending on if iAd fails or not now. For example, iAd loads so set its hidden value to NO and AdMob’s to YES, and vice versa if iAd fails to load an ad. I’m sure you were checking the IAP every time in case the user purchased it while in the current session so you could remove the ads. An easier solution would be to move the ads outside of the screen bounds on completion of the IAP and then on the next launch of your application simply do not create either banner at all if [[NSUserDefaults standardUserDefaults] boolForKey:@"IAPSuccessful"] is true. A few other things to point out are, you should remove your request.testDevices AdMob request before submitting your application, and it seems you are defining your NSLayoutConstraint *myConstraint multiple times. I’m not exactly sure what you’re trying to do here. Also, in didFailToReceiveAdWithError you have self.adBanner.hidden = true, it should be self.adBanner.hidden = YES.

If you're using em's then you first need to define a base value for the font. Ex.:

body { font-size: 16px }

Now 1em = 16px.

Most browsers have a default user-agent font-size of 16px but you shouldn't rely on it. Set the base value then start using em's.

which will search myfile.txt relative to the working directory executing your application. It works also with subfolders:

The MapPath function you are referring to in your question is used in ASP.NET applications and allows you to retrieve the absolute path of a file given it's virtual path. For example:

Server.MapPath("~/foo/myfile.txt")

and if your site is hosted in c:\wwwroot\mysite it will return c:\wwwroot\mysite\foo\myfile.txt.

I have the following method where it is suppose to get the first image that is displayed from the content.

public function FirstImage($content) { $dom = new DOMDocument(); $dom->loadHTML($content); Debug::dump($content); }

The wierd thing is when i do $dom->loadHTML I get the following error Empty string supplied as input, but as soon as I dump it I do get the correct data. How can I fix this problem ?

I also done $this->owner->Content which has the same thing.

If you want to use it more times in your program then it's maybe a good idea to make a custom class inherited from StreamReader with the ability to skip lines.

Something like this could do:

class SkippableStreamReader : StreamReader { public SkippableStreamReader(string path) : base(path) { } public void SkipLines(int linecount) { for (int i = 0; i < linecount; i++) { this.ReadLine(); } } }

after this you could use the SkippableStreamReader's function to skip lines. Example:

SkippableStreamReader exampleReader = new SkippableStreamReader("file_to_read"); //do stuff //and when needed exampleReader.SkipLines(number_of_lines_to_skip);

31658826 0 Scraping dynamic web pages using Python 3.4 and beautifulsoup

OK, using Python 3.4 and beautifulsoup4 on a windows 7 VM. Having trouble scraping the data resulting from making a selection with a drop-down list. As a learning experience, I'm trying to write a scraper that can select the 4 year option on this page: www.nasdaq.com/symbol/ddd/historical and print the rows of the resulting table. So far, it just prints out the default 3 month table, along with some junk at the beginning that I don't want. Eventually I would like to scrape this data and write it to DB using mysql python connector, but for now I would just like to figure out how to make the 4 year selection in the drop down list. (also, would like to get rid of the text encoding that causes it to be in the b'blahblah' format. My code so far:

from bs4 import BeautifulSoup import requests url = 'http://www.nasdaq.com/symbol/ddd/historical' with requests.Session() as session: session.headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36'} response = session.get(url) soup = BeautifulSoup(response.content) data = { 'ddlTimeFrame': '4y' } response = session.post(url, data=data) soup = BeautifulSoup(response.content) for mytable in soup.find_all('tbody'): for trs in mytable.find_all('tr'): tds = trs.find_all('td') row = [elem.text.strip().encode('utf-8') for elem in tds] print (row)

I get no errors, but it doesn't print out the 4 year data. Thanks for your time/patience/help!

38639066 0 Angular textarea validation error

I have a textarea in my app like so:

<textarea type="text" class="form-control" name="bioBackground" ng-model="obj.background" value="obj.background" ng-change="autosave()" maxlength="1500" required></textarea>

This is a required field and as you can see I have added a required tag in the code. But this required tag is causing errors with Angular.

For example:

If I type in the field and backspace and remove all the text it removes the object from the scope. see example below:

Before Backspacing

You can see background variable is in the scope.

After backspacing and removing the text:

You can see the background variable is gone from scope.

This only happens if I use required tag. If I don't use the required tag it works fine and even after removing all the text the background variable stays within the scope.

What am I doing wrong.

2616378 0 can't write to physical drive in win 7?

I wrote a disk utility that allowed you to erase whole physical drives. it uses the windows file api, calling :

destFile = CreateFile("\\\\.\\PhysicalDrive1", GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING,createflags, NULL);

and then just calling WriteFile, and making sure you write in multiples of sectors, i.e. 512 bytes.

this worked fine in the past, on XP, and even on the Win7 RC, all you have to do is make sure you are running it as an administrator.

but now I have retail Win7 professional, it doesn't work anymore! the drives still open fine for writing, but calling WriteFile on the successfully opened Drive now fails!

does anyone know why this might be? could it have something to do with opening it with shared flags? this is always what I have done before, and its worked. could it be that something is now sharing the drive? blocking the writes? is there some way to properly "unmount" a drive, or at least the partitions on it so that I would have exclusive access to it?

some other tools that used to work don't any more either, but some do, like the WD Diagnostic's erase functionality. and after it has erased the drive, my tool then works on it too! leading me to believe there is some "unmount" process I need to be doing to the drive first, to free up permission to write to it.

Any ideas?

Update:

the error code returned from WriteFile is '5', ERROR_ACCESS_DENIED but again, if I 'erase' the drive first using WD Diag, I can then access and write to the drive fine. when I initialize the drive again, and give it a partition, I go back to getting the ERROR_ACCESS_DENIED error.

8584034 0 Why are all anonymous classes implicitly final?

According to the JLS:

15.9.5 Anonymous Class Declarations An anonymous class declaration is automatically derived from a class instance creation expression by the compiler.

An anonymous class is never abstract (§8.1.1.1). An anonymous class is always an inner class (§8.1.3); it is never static (§8.1.1, §8.5.2). An anonymous class is always implicitly final (§8.1.1.2).

This seems like it was a specific design decision, so chances are it has some history.

If I choose to have a class like this:

SomeType foo = new SomeType() { @Override void foo() { super.foo(); System.out.println("Hello, world!"); } };

Why am I not allowed to subclass it again if I so choose?

SomeType foo = new SomeType() { @Override void foo() { super.foo(); System.out.println("Hello, world!"); } } { @Override void foo() { System.out.println("Hahaha, no super foo for you!"); } };

I'm not saying I necessarily want to, or can even think of a reason why I would. But I am curious why this is the case.

Using includeInLayout ="true" or "false" will toggle the space that it takes in the flow of items being rendered in that section.

Important note: If you don't specify visible="false" when using includeInLayout = "false" then you will usually get something that is undesired which is that your item (boxAddComment) is still visible on the page but stuff below id="boxAddComment" will overlap it visually. So, in general, you probably want "includeInLayout" and "visible" to be in synch.

The difference here, I call the myfunc without the '()'.

Can anyone explain the reason?

Your problem is not occuring at the GROUP BY level, but rather in the JOIN. The rows with a NULL qualifier cannot be JOINed and, because you're using INNER JOIN, they fall out of the result set.

Use LEFT OUTER JOIN to see all the rows.

Since the price requires a decimal value we should supply it a decimal value. Try the following view:

def get_queryset(self, *args, **kwargs): qs = super(ProductListView, self).get_queryset(*args,**kwargs) query = self.request.GET.get("q", False) # provide default value or you get a KeyError if query: filter_arg = Q(title__icontains=query) | Q(description__icontains=query) try: filter_arg |= Q(price=float(query)) except ValueError: pass qs = self.model.objects.filter(filter_arg) return qs

qs = super(ProductListView, self).get_queryset(*args,**kwargs) This is used to obtain the queryset provided by the parent classes of our view class ProductListView. Look in to python classes and inheritance here: http://www.jesshamrick.com/2011/05/18/an-introduction-to-classes-and-inheritance-in-python/

filter_arg |= Q(price=float(query)) this is used to append to our filter_arg value. It's the same as filter_arg = filter_arg | Q(price=float(query)

float(query) with this we are trying to convert the query variable to a float and we put this in a try statement because it could give us a ValueError in which case the query value is not a float.

I've got two approaches for you:

Firstly using Activator.CreateInstance

public static IEnumerable<TV> To<TU, TV>(this IEnumerable<TU> source) { return source.Select(m => (TV) Activator.CreateInstance(typeof(TV), m)); }

Secondly, you could use interfaces to define properties rather than use parameterized constructors:

public interface IRequiredMember {} public interface IHasNeccesaryMember { IRequiredMember Member { get; set; } } public static IEnumerable<TV> To<TU, TV>(this IEnumerable<TU> source) where TV : IHasNeccesaryMember, new() where TU : IRequiredMember { return source.Select(m => new TV{ Member = m }); }

The first method works but feels dirty and there is the risk of getting the constructor call wrong, particularly as the method is not constrained.

Therefore, I think the second method is a better solution.

You are looking for the two properties:

In your case, you have to set the combobox's ValueMember property to value1 and the DisplayMember property to option1.

Update: The following is an exmple of how you can populate the items of a combobox from list of some entity Foo:

public class Foo(){ public string Id { get; set; } public string Name { get; set; } } var ds = new List<Foo>(){ new Foo { Id = "1", Name = "name1" }, new Foo { Id = "2", Name = "name2" }, new Foo { Id = "3", Name = "name3" }, new Foo { Id = "4", Name = "name4" }, }; comboboxName.DataSource = ds; comboboxName.ValueMember = "Id"; comboboxName.DisplayMember = "Name";

Update2: That's because you are adding the same object each time. In the following block of your code:

Foo categoryInsert = new Foo(); foreach (string s in categories) { categoryInsert.path = s; categoryInsert.name = s; combo3data.Add(categoryInsert); }

Each time The foreach iterate over the categories, all what it does, is changing the same object categoryInsert's values path and name not creating a new one. Thus, you end up with the same object added in each iteration to the combo3data. What you need is create a new Foo object inside the foreach itself each time, i.e: move the Foo categoryInsert = new Foo(); inside the foreach loop. Something like:

foreach (string s in categories) { Foo categoryInsert = new Foo(); categoryInsert.path = s; categoryInsert.name = s; combo3data.Add(categoryInsert); }

I have an app using Firebase and Angularjs. If I put a listener on onAuthStateChanged, it seems to fire every time I navigate to a new url in my site, and the Angularjs Route changes. This seems undesirable/incorrect? Anyone else experience this? E.g. if I do this in a controller:

 firebase.auth().onAuthStateChanged(function(user) { if (user) { alert("changed"); } });

every time the route changes the alert pops up.

Since the logged in state of the user doesn't seem to be changing, why would this listener fire? I think I am missing something. Anyone understand what's going on?

There are multiple ways to do what you are trying to do, the easiest one would be the following:

OutputDict = {} for key in Dict1.iterkeys(): if key in Dict2: OutputDict[key] = Dict1[key] + Dict2[key][2]

2093416 0 Group by and non distinct columns and data normalization

I have a large table(60 columns, 1.5 million records) of denormalized data in MS SQL 2005 that was imported from an Access database. I've been tasked with normalizing and inserting this data into our data model.

I would like to create a query that used a grouping of, for example "customer_number", and returned a result set that only contains the columns that are non distinct for each customer_number. I don't know if it's even possible, but it would be of great help if it was.

Edit:if my table has 3 columns(cust_num,cust_name_cust_address) and 5 records

|cust_num|cust_name|cust_address |01 |abc |12 1st street |02 |cbs |1 Aroundthe Way |01 |abc |MLK BLVD |03 |DMC |Hollis Queens |02 |cbs |1 Aroundthe Way

the results from my desired query should just be the data from cust_num and cust_name because cust_address has different values for that grouping of cust_num. A cust_num has many addresses but only one cust_name.

Can someone point me in the right direction?

One clear benefitial way would be to read the large data into a database (postgresql or mariadb for instance). But I'll assume this isn't at all possible for now.

In regards to a CSV reader, they're fine but maybe not so efficient.
Since you're going to read through both files anyway I would consider the following:

Read the 13GB file line by line and save the ID in a dictionary without checking if the key/value exists. (why? Because checking if the value exists is slower than just overwriting it and dictionaries also has a added bonus that keys are unique so duplicates will be weeded out) or add it to a set() as described by many others.

followed by reading the smaller file line by line and checking your dict or set if it contains the ID.

`dict()` vs `set()` vs `list()`

Here's a comparison between the three data types set(), list() and dict():
code used: test.py

(11.719028949737549, 999950, 'Using dict() for inserts') (1.8462610244750977, 'dict() time spent looking through the data') (11.793760061264038, 999961, 'Using set() for inserts') (7.019757986068726, 'set() time spent looking through the data') (15min+, 'Using list()') # Honestly, I never let it run to it's finish.. It's to slow.

As you can see dict is marginally quicker than set, while list() just falls behind completely (see description of why by Antti). I should point out my data is a bit skewed since it's a quick and dirty demo of the speed difference, but the general idea should still come across.

Using dict() as a solution

So if you do not have access to a database version of the source-data, and you need to use Python, id go with something along the lines of:

delimiter = b'\x01' big_source = {} with open('13_gig_source.log', 'rb') as fh: for line in fh: csv = line.split(delimiter) big_source[csv[4]] = None # 5:th column, change to match CUSTOMER_ID output = open('result.log', 'wb') with open('smaller_file.log', 'rb') as fh: for line in fh: csv = line.split(delimiter) if csv[4] in big_source: output.write(csv[4] + b'\n') output.close()

Since I didn't know which column the data exists on i didn't optimize the split().
For instance, if it's the last column you're trying to fetch, do line.rsplit(delimiter, 1)[-1] instead. Or if it's the 3:d column do line.split(delimiter, 3)[2] because it will abort the process of looking for the next position of the delimiter in the split() functions.

Using linux tools

Yes, some tools might be better off suited for this such as awk because of the fact that it's a specific tool written in C to perform a very specific task. Even tho Python is based on C it still has a lot of abstraction layers on-top of that C code and will for the most part be slower than the counterpart C tools written for specific tasks.

Now I have no data to test this with, nor am i a PRO With Nix-Commands or PWN-C for short. So I'll leave someone else to give you examples of this, but i found this:

merge two csv files according to matching rows and add new columns in linux

And it might be helpful.

6338456 0 sequentially including various View classes in a parent layout

I have a main layout in which I'd like to sequentially display / hide various custom layouts according to timers and user input.

In my example, I'd like the following timeline:

show an initial layout, created by the class MainStart. The user will click on the button when they're ready to start.
after the user clicks, we'll run a countdown timer, displaying the countdown to the screen. This is done by MainCountdown.
once the countdown is complete, MainLast is displayed. It has a button allowing the user to click "Again?" when they want to start over.
if the user clicks "Again?" then go to step 1.

According to this question, I may have to use removeView() and addView() to achieve what I want.

I pushed to GitHub a trimmed down version of what I want to do: Hide and Show Layouts so you can see everything, but the problem seems to boil down to myView still being visible after this:

myView = inflate(mContext, R.layout.main_start, _view_group); myView.setVisibility(View.GONE);

direct link to code on GitHub

direct link to related layout

Can I make a small change to my code/layouts to make the views hide/appear the way I want?

Am I completely Doing It Wrong?

If you are using c#, you can simplify your life and use two separate regex:

bool res = false; string str = // your string if (str < 8) { res = Regex.IsMatch(str, @"^[0-9]+$"); } else { res = Regex.IsMatch(str, @"^(?=[a-zA-Z0-9]*[a-zA-Z])[a-zA-Z0-9]*$"); }

You can use :

git config --get-regexp user.name

For the user name. for the repository name, you may have different repositories with different names, so I guess parsing :

git remote get-url origin

could help if you only care about the origin ? The format would be (prefixes would differ between ssh or https) git@github.com:{github_handle}/{repo_name}.git

36960628 0 How to return results together with update operations in BaseX?

I recognized that (insert/delete)-XQueries executed with the BaseX client always returning an empty string. I find this very confusing or unintuitive.

Is there a way to find out if the query was "successful" without querying the database again (and using potentially buggy "transitive" logic like "if I deleted a node, there must be 'oldNodeCount-1' nodes in the XML")?

You're asking for the filesize of a directory, which in this case is 4,096 bytes. This number will vary for a directory depending on what sort of filesystem you're using and how many files are in it.

2940823 0 generateUrl problem

I am trying to generate a url but I keep getting a strange warning even though it works. I am making an api xml page and I use the following call in the controller:

public function executeList(sfWebRequest $request) { $this->users = array(); foreach($this->getRoute()->getObjects() as $user) { $this->users[$this->generateUrl('user_show', $user, true)] = $user->asArray($request->getHost()); } }

The user_show route is as follows:

# api urls user_show: url: /user/:nickname param: { module: user, action: show }

And the xml outputs as follows:

<br /> <b>Warning</b>: array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br /> <br /> <b>Warning</b>: array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br /> <br /> <b>Warning</b>: array_diff_key() [<a href='function.array-diff-key'>function.array-diff-key</a>]: Argument #1 is not an array in <b>/opt/local/lib/php/symfony/routing/sfRoute.class.php</b> on line <b>253</b><br /> <?xml version="1.0" encoding="utf-8"?> <users> <user url="http://krowdd.dev/frontend_dev.php/user/danny"> <name>Danny tz</name> <nickname>danny</nickname> <email>comedy9@gmail.com</email> <image></image> </user> <user url="http://krowdd.dev/frontend_dev.php/user/adrian"> <name>Adrian Sooian</name> <nickname>adrian</nickname> </user> </users>

So it outputs the correct xml but I do not know why it throws thows warning when calling the generateurl method.

Thanks!

With mapsforge you cannot do this. You have to use a routing library like graphhopper is one. See here how to use it: http://graphhopper.com/#developers.

But there are other offline and online routers as well. Have a look here: http://wiki.openstreetmap.org/wiki/Routing/offline_routers and here http://wiki.openstreetmap.org/wiki/Routing

If there is some PHP behind, the problem could be calling a function empty($var) in this way:

if(empty($var = getMyVar())) { ... }

Instead of this You should call it this way:

$var = getMyVar(); if(empty($var)) { ... }

Or better (as deceze has pointed out)

if(!getMyVar()) { ... }

Problem causes also other similar functions (isset, is_a, is_null, etc).

I assume that you don't use nginx to serve static assets in development? Runserver can serve static files, but very much slower than nginx, which becomes a problem once you have more than a single web site visitor at a time. You can remove the nginx alias for static and reload nginx to let runserver serve the files, to confirm whether it's a problem in the nginx config. Håken Lid

I removed nginx and made the Django server load the static files, and now I can show it to my future users. This answered my question, though it did not solve the problem itself! Thanks anyway !

Check the following tutorial, it appears to be for the latest version of TinyMCE (and it is updated recently).

https://www.gavick.com/blog/wordpress-tinymce-custom-buttons

The tutorial you linked is probably for the TinyMCE that was in WordPress prior to 3.9.

Edit: Did a quick test. Seems to be working. :)

A quick guide to get it working:

Open https://www.gavick.com/blog/wordpress-tinymce-custom-buttons#tmce-section-1
Paste the four codes of php in your functions.php file
Replace plugins_url( '/text-button.js', __FILE__ ); with get_bloginfo('stylesheet_directory') . /text-button.js (might need adjusting if the file is in a subdirectory).
Paste the javascript code from the fifth block in the javascript file you created.

(note this is just a quick example for implementing it in a theme so you can get the main idea, if you are actually building a plugin, you should use the plugins_url( '/text-button.js', __FILE__ ) syntax).

What is the best practice to securely upload an image to a php script based on my code below? I'm using the file transfer cordova plugin to upload the image to a php script.

Javascript (file transfer cordova plugin)

For basic types like int, NoneType, dict and other simple cases there's a natural "factory" in Python - it is ast.literal_eval.

>>> import ast >>> ast.literal_eval('None') is None True >>> ast.literal_eval('{1: 2}') {1: 2} >>> ast.literal_eval('1e6') 1000000.0

So if your data is a superposition of basic types (something json-like for instance), then you can parse it with single ast.literal_eval call. Unlike exec and eval, ast.literal_eval is much safer as you can't run any code with it.

When you create your documents, you must set the creation date:

MyCollection.insert({ text: "abc", createdAt: new Date() });

then, you can filter your data:

If you want the documents created in an interval:

MyCollection.find( {createdAt: { $gte: new Date("Sat Jul 30 2016 8:00:00"), $lt: new Date("Sat Jul 30 2016 9:00:00"), }}, {sort: {createdAt:1}});
Or documents created exactly at 8am:

MyCollection.find({createdAt: new Date("Sat Jul 30 2016 8:00:00")});

Hope it helps.

The problem was a bit tricky but I manage to solve it.

The fact is: if a real postback is not executed (responding with a file is not considered so) the value is still considered "changed".

The only way to solve this problem seems to be "resetting" manually the value of the hiddenfield.

I came up with this:

self.getExcel = function (stringBase64) { $("#hiddenFiedlName").val(stringBase64); __doPostBack(); $("#hiddenFieldName").val(""); }

After the postback the value is restored to the initial one (which is always the empty string). By doing this the "ValueChanged" event is not triggered.

As stated in the comment of jbl the change() was useless (please refer to his comment in the question).

I have found the solution. The problem was that I was trying to use the adapter to get an reference to the views above and below the list item clicked. Instead I could find the appropriate views by using the getChildAt() method on the parent view (the listview itself).

It was as easy as writing:

View aboveView = parent.getChildAt(position -1) View aboveViewShadow = aboveView.findViewById(R.id.settingsListRowShadowAbove); aboveViewShadow.setVisibility(View.VISIBLE);

I am using the OptaPlanner to optimize a chained planning problem which is similar to the VehicleRoutingExample. My planning entities have a planning variable which is another planning entity.

Now I am testing a huge dataset with ca. 1500 planning entities. I am using an EasyJavaScoreCalculator to get a HardSoftScore. The Score includes several time and other factors which are calculated in loops.

My Problem is that the ConstrucionHeuristic (FIRST_FIT or FIRST_FIT_DECREASING) takes more than ten minutes to initialize a Solution.

I have already reduced the number of constraints and the number of loops with which I am calculating the score, but it did not have a real effect on the running duration.

Is there a way to make the CH need less time? (I thought that it would take less time than the LocalSearch stuff but it isn’t…)

This appears to be basically a duplicate of SQL Server Random Sort which is basically a duplicate of How to request a random row in SQL?.

The latter has a comprehensive answer for multiple RDBMSs referencing this post:

SQL to Select a random row from a database table

An answer for Microsoft SQL Server would be:

SELECT TOP 10 * FROM table ORDER BY NEWID();

This will not perform well on large tables. It scans the entire table, generating a unique number (a 16-bit GUID) for each row, and then sorts the results by that unique number.

Simply ordering by RAND() in SQL Server will not result in a random list of records. RAND() is evaluated once at the beginning of the statement, so you are effectively ordering by a constant, which isn't really ordering at all. You'll get the same results without the ORDER BY. Indeed, in my instance of SQL Server 2005, the query plans and results were the same with and without the ORDER BY RAND().

RAND() in SQL Server takes a seed value, so you might think that you could pass a varying table column value into the RAND function and get random results. In some sense, you can. You could pass an IDENTITY or other unique column into the RAND function and you won't get the same order as without. And the order will be random in the sense that it appears so to a casual observer. But it's repeatable. The RAND() function in SQL Server will always return the same value for the same seed on the same connection:

"For one connection, if RAND() is called with a specified seed value, all subsequent calls of RAND() produce results based on the seeded RAND() call."

http://technet.microsoft.com/en-us/library/ms177610.aspx

So while you would get what appeared to be a random list, if you executed it multiple times in the same connection, you would get the same list. Depending on your requirements, that might be good enough.

Based on my limited tests on a small table, the RAND with a unique column seed had a very slightly lower estimated query cost.

15371413 0 How to convert a SPARQL query into an RDF file in Jena?

I am trying to output an RDF/XML file directly from an SPARQL query from an Oracle database. The query is working fine as I've verified the results in the ResultSet object.

However, I'm not sure how to proceed from there. I think I want to create a Statement for each QuerySolution and then add it to the Model. However I can't figure out a way to do it, because I can't find a way to get the predicate value.

Any help would be appreciated, as well as hints whether I am going down the right path.

QueryExecution qe = QueryExecutionFactory.create(query, oracleSemModel) ; ResultSet results = qe.execSelect(); Model model = ModelFactory.createDefaultModel(); while (results.hasNext()) { QuerySolution result = results.next(); Resource subject = result.getResource("s"); // get the subject Property predicate = result.getProperty("p"); // <-- THIS FUNCTION DOESN'T EXIST RDFNode object = result.get("o"); // get the object Statement stmt = ResourceFactory.createStatement(subject, predicate, object); model.add(stmt); } model.write(System.out, "RDF/XML-ABBREV");

Say you have two versions of the gem foo installed:

$ gem list foo *** LOCAL GEMS *** foo (2.0.1, 2.0.0)

If you use only require, the newest version will be loaded by default:

require 'foo' # => true Foo::VERSION # => "2.0.1"

If you use gem before calling require, you can specify a different version to use:

gem 'foo', '2.0.0' # => true require 'foo' # => true Foo::VERSION # => "2.0.0"

Note: using gem without subsequently calling require does not load the gem.

gem 'foo' # => true Foo::VERSION # => NameError: uninitialized constant Foo

One goal of Groovy is to have transparent interoperability with Java. Groovy is by design "a Java dependent language with scripting features". However, I don't think that these features are minor - Groovy has many features that are not found in static programming languages (such as Java).

To summarize: If you don't care at all about Java, then use a more general-purpose scripting language, such as Python or Perl. If you want to use the Java code-base in a script-ish way, Groovy is a good option.

I can think of two and a half pure CSS solutions.

First solution requires to wrap all four div's in a container element with position: relative set to it.

Then the blue div can be positioned absolutely and forced to inherit the containers/wrappers height (which comes from the total height of the yellow and green div's) like so:

position: absolute; top: 0; right: 0; bottom: 0;

The width of the blue div can be set explicitly, or with left, depending on how responsive the layout needs to be. And the horizontal space taken up by the blue div can be compensated on the wrapper with padding-right.

But no-one really wants extra DOM elements to achieve proper layout, do they.

Another option would be to set position: relative on the green div and place the blue div as a child of the green div in the DOM. Then position the blue div so:

position: absolute; left: 100%; top: -x; /* Whatever is the height of the top yellow div and margin between*/ bottom: x; /* Whatever is the height of the bottom yellow div and margin between */ width: x; /* Set explicitly for example */

This is possible due to the fact that yellow div's are of fixed height.

And extending it further, the entire blue div can be accomplished by the ::after pseudo element on the green div (same CSS applies as for the second solution), but it's suitability depends on what the contents of the blue div need to be.

The image on a UIImageView is an UIImage optional, meaning that it can have a value (contain an image) or it can be nil.

So, when you're saying:

let ocrSample = myImageView.image

your ocrSample is now an UIImage optional, which you then have to unwrap before you use it.

When you then say:

tesseract.image = ocrSample!.fixOrientation().g8_blackAndWhite()

you are force unwrapping your ocrSample by using !, meaning that you are telling the compiler to just unwrap and use the optional, regardless of it being nil or not. This causes a crash when you then try to use that unwrapped optional if it contains nil.

What you can do is unwrap ocrSample using an if let like so:

func checkWithOCR() throws{ if let ocrSample = myImageView.image { tesseract.image = ocrSample.fixOrientation().g8_blackAndWhite() if(tesseract.recognize()){ let recognizedText = tesseract.recognizedText if recognizedText != nil{ print("recognizedText: \(recognizedText)") let trimmedText = String(recognizedText.characters.filter { !" \n\t\r,".characters.contains($0) }) myImageView.image = tesseract.image convertCurrency(Float(trimmedText)!) //convert the tesseract text } } SwiftSpinner.hide() } else { //No value could be found, do your error handling here } }

Here:

if let ocrSample = myImageView.image

you are trying to unwrap the value of myImageView.image into ocrSample, if that succeeds, then you know for sure that ocrSample is not nil and can use it onwards. If it fails, then you can do your error handling, show an alert view and whatever else you need to do.

Hope that helps you.

You need to call rect for each colour that you want to draw, and have those colours in a categorical column in your data frame so that you can filter the data per category for each call to rect.

I don't know what your original data is like, so here's something similar:

# set up simple plotting window plot.new() plot.window(xlim=c(0,6),ylim=c(0,8)) # example data. Using colour as the categorical value we will filter on sample.d <- data.frame(x=c(3,4,5,6), yb=c(1,3,5,7), yt=c(0,2,4,6), colour=c("black","black","red","red")) # draw black rectangles black.d <- sample.d[sample.d$colour == "black",] rect(0, black.d$yb, black.d$x, black.d$yt, col="black") # draw red rectangles red.d <- sample.d[sample.d$colour == "red",] rect(0, red.d$yb, red.d$x, red.d$yt, col="red")

You need to set an expectation on the UsarioService to say what will be returned when usarioService.save(...) is called.

Before getting to that point, you need to say in the test mockUsarioService.createMock() which will create the actual instance of the mock object, that's what you will pass to the controller usarioService attribute. Copied the code below from the Grails documenation. http://grails.org/doc/1.1/guide/9.%20Testing.html

17684793 0 Stacked shield doesn't have enough power -- dim PWR light

I'm stacking a SeeedStudio Bluetooth Shield on top of a Olimex EKG/EMG Shield.

At first, I stacked the two loading only bluetooth shield demo code and all the LEDs lit up brightly and worked fine.

Now (having only taken a shield off and put it back on), the lower shield's (Olimex) power LED appears dim and the upper shield (Bluetooth) is not powered at all. The lower shield's power LED brightens when I remove the top shield.

Not sure what happened here -- both shields work perfectly if they are the ONLY shield on top of the Arduino. Is there any way for me to check the output voltage coming from the lower shield (Olimex) to the higher shield (Bluetooth) with a multimeter to see if it's sufficient (3.3V)?

This function takes a string argument as input

The first thing it does is checks the recursive base case. We'll get back to that

If the base case is not satisfied, it then checks to see if the first character matches the last character using this code:

if (substr($string,0,1) == substr($string,(strlen($string) - 1),1))

If that does match, then the function recursively calls itself again but this time with the first and last character removed, this is done with this line

return Palindrome(substr($string,1,strlen($string) -2));

If ever the first character does not match the last character, the function automatically outputs to html "STRING IS NOT A PALINDROME via echo

Now back to the base case I mentioned before, if the function successfully matches and removes the first and last character until there are one or no characters left, then the string has been confirmed to be a palindrome and it echos that string.

If you need help with recursion let me know, I'll post a tutorial link

The li elements are hard coded into your list. To put them into a div you can either hard code them into the preferred div or use javascript to dynamically change the html code. It would probably be easier to just code a short list into the adjacent div, but if this is a list that gets generated in some way, css can change how things are displayed, but the location of you li items are still part of the parent div. Css is for styling and placing on the screen not for changing parent elements.

You should go with the second approach.

One possible solution is a greedy algorithm. Define your set of transformations as a regular expression (used to test the pattern) and a function which is given the regexp match object and returns the transformed string.

Regular expressions aren't quite powerful enough to handle what you want directly. Instead you'll have to do something like:

m = re.match(r"C\[(\d+)\]H\[(\d+)]\]", formula) if m: C_count, H_count = int(m.group(1)), int(m.group(2)) match_size = len(m.group(0)) if C_count*2+2 == H_count: replacement = alkane_lookup[C_count] elif C_count*2 == H_count: replacement = alkene_lookup[C_count] ... else: replacement = m.group(0) # no replacement available

(plus a lot more for the other possibilities)

then embed that in a loop which looks like:

formula = "...." new_formula = "" while formula: match_size, replacement = find_replacement(formula) new_formula += replacement formula = formula[match_size:]

(You'll need to handle the case where nothing matches. One possible way is to include a list of all possible elements at the end of find_replacement(), which only returns the next element and counts.)

This is a greedy algorithm, which doesn't guarantee the smallest solution. That's more complicated, but since chemists themselves have different ideas of the right form, I wouldn't worry so much about it.

Linear Diophantine equations take the form ax + by = c. If c is the greatest common divisor of a and b this means a=z'c and b=z''c then this is Bézout's identity of the form

enter image description here

with a=z' and b=z'' and the equation has an infinite number of solutions. So instead of trial searching method you can check if c is the greatest common divisor (GCD) of a and b (in your case this translates into bx - dy = c - a)

If indeed a and b are multiples of c then x and y can be computed using extended Euclidean algorithm which finds integers x and y (one of which is typically negative) that satisfy Bézout's identity

enter image description here

and your answer is:

a = k*x, b = k*y, c - a = k * gcd(a,b) for any integer k.

(as a side note: this holds also for any other Euclidean domain, i.e. polynomial ring & every Euclidean domain is unique factorization domain). You can use Iterative Method to find these solutions:

Iterative method

By routine algebra of expanding and grouping like terms (refer to last section of wikipedia article mentioned before), the following algorithm for iterative method is obtained:

1 . Apply Euclidean algorithm, and let qn (n starts from 1) be a finite list of quotients in the division.
2 . Initialize x0, x1 as 1, 0, and y0, y1 as 0,1 respectively.
- 2.1 Then for each i so long as qi is defined,
- 2.2 Compute xi+1 = xi−1 − qixi
- 2.3 Compute yi+1 = yi−1 − qiyi
- 2.4 Repeat the above after incrementing i by 1.
3 . The answers are the second-to-last of xn and yn.

pseudocode:

function extended_gcd(a, b) x := 0 lastx := 1 y := 1 lasty := 0 while b ≠ 0 quotient := a div b (a, b) := (b, a mod b) (x, lastx) := (lastx - quotient*x, x) (y, lasty) := (lasty - quotient*y, y) return (lastx, lasty)

So I have written example algorithm which calculates greatest common divisor using Euclidean Algorithm iterative method for non-negative a and b (for negative - these extra steps are needed), it returns GCD and stores solutions for x and y in variables passed to it by reference:

int gcd_iterative(int a, int b, int& x, int& y) { int c; std::vector<int> r, q, x_coeff, y_coeff; x_coeff.push_back(1); y_coeff.push_back(0); x_coeff.push_back(0); y_coeff.push_back(1); if ( b == 0 ) return a; while ( b != 0 ) { c = b; q.push_back(a/b); r.push_back(b = a % b); a = c; x_coeff.push_back( *(x_coeff.end()-2) -(q.back())*x_coeff.back()); y_coeff.push_back( *(y_coeff.end()-2) -(q.back())*y_coeff.back()); } if(r.size()==1) { x = x_coeff.back(); y = y_coeff.back(); } else { x = *(x_coeff.end()-2); y = *(y_coeff.end()-2); } std::vector<int>::iterator it; std::cout << "r: "; for(it = r.begin(); it != r.end(); it++) { std::cout << *it << "," ; } std::cout << "\nq: "; for(it = q.begin(); it != q.end(); it++) { std::cout << *it << "," ; } std::cout << "\nx: "; for(it = x_coeff.begin(); it != x_coeff.end(); it++){ std::cout << *it<<",";} std::cout << "\ny: "; for(it = y_coeff.begin(); it != y_coeff.end(); it++){ std::cout << *it<<",";} return a; }

by passing to it an example from wikipedia for a = 120 and b = 23 we obtain:

int main(int argc, char** argv) { // 120x + 23y = gcd(120,23) int x_solution, y_solution; int greatestCommonDivisor = gcd_iterative(120, 23, x_solution, y_solution); return 0; }

r: 5,3,2,1,0,

q: 5,4,1,1,2,

x: 1,0,1,-4,5,-9,23,

y: 0,1,-5,21,-26,47,-120,

what is in accordance with the given table for this example:

The answer is highly situational. In general, you want to handle exceptions elegantly whenever possible. That is, try to resolve / ignore them where you can. An IndexOutOfBoundsException is very often an example of where this is not possible.

Hard breaks because of exceptions is a last-resort. Do this only when your program cannot continue.

This question's answer has a good post on it. When to throw an exception?

Im upgrading my UI to iOS 7, and have been using a custom tab bar which has a CAShapeLayer used as a mask. Ive been trying to add dynamic blur by having a UIToolBar underneath, but if i try setting the layer.mask property on the toolbar translucency is gone, and i just have it semi transparent (but masking works of course). Is there a way to get this working? Ive also seen this behavior when adding a subview to these classes.

Do you set the constraint for the label. or the label is too height for the superview , so it covers the all subviews , so you can use the lldb po the label size ,when you set the text into the label.

on the second approach i will get a notification if the 'controller' object on self was replaced

I would rephrase by saying that on the second approach you'll get notified if the controller object gets replaced or if its isEnabled property changes. In other word when controller.isEnabled changes (as explained by Ken's answer).

Check this example:

- (void)viewDidLoad { [super viewDidLoad]; self.controller = [[ViewController2 alloc] init]; [self.controller addObserver:self forKeyPath:@"isEnabled" options:NSKeyValueObservingOptionNew context:nil]; [self addObserver:self forKeyPath:@"controller.isEnabled" options:NSKeyValueObservingOptionNew context:nil]; dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ self.controller.isEnabled = !self.controller.isEnabled; // replace controller [self.controller removeObserver:self forKeyPath:@"isEnabled"]; self.controller = [[ViewController2 alloc] init]; dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ self.controller.isEnabled = !self.controller.isEnabled; }); }); } - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { NSLog(@"KVO %d %@ %p", self.controller.isEnabled, keyPath, self.controller); }

We'll get 4 KVO notifications:

KVO 1 controller.isEnabled 0x7fbbc2e4b4e0 <-- These 2 fire together when we toggle isEnbled KVO 1 isEnabled 0x7fbbc2e4b4e0 <-- So basically 1. and 2. behave the same KVO 0 controller.isEnabled 0x7fbbc2e58d30 <---- controller was replaced KVO 1 controller.isEnabled 0x7fbbc2e58d30 <---- Toggle on the new instance

I am using the Microsoft Live SDK for Windows Phone to access SkyDrive and get an exception in Microsoft.Live.dll. I'd like to step through the source to debug the issue, but fetching symbols from symbol server http://msdl.microsoft.com/download/symbols fails.

I followed these instructions on how to set up the symbol server in my dev environment. The environment variable _NT_SYMBOL_PATH is set to srv*c:\symbols*http://msdl.microsoft.com/download/symbols. This seems to work for other assemblies. While debugging I see the symbol cache at c:\symbols grow with entries, but Microsoft.Live is missing.

5833026 0 Extract IPTC information from JPEG using Javascript

I'm trying to extract IPTC photo caption information from a JPEG file using Javascript. (I know I can do this server-side, but I'm looking specifically for a Javascript solution.)

I found this script, which extracts EXIF information ... but I'm not sure how to adapt it to grab IPTC data.

Are there any existing scripts that offer such functionality? If not, how would you modify the EXIF script to also parse IPTC data?

UPDATE

I've modified the EXIF script I linked above. It sorta does what I want, but it's not grabbing the right data 100 percent of the time.

After line 401, I added:

else if (iMarker == 237) { // 0xED = Application-specific 13 (Photoshop IPTC) if (bDebug) log("Found 0xFFED marker"); return readIPTCData(oFile, iOffset + 4, getShortAt(oFile, iOffset+2, true)-2); }

And then elsewhere in the script, I added this function:

function readIPTCData(oFile, iStart, iLength) { exif = new Array(); if (getStringAt(oFile, iStart, 9) != "Photoshop") { if (bDebug) log("Not valid Photoshop data! " + getStringAt(oFile, iStart, 9)); return false; } var output = ''; var count = 0; two = new Array(); for (i=0; i<iLength; i++) { if (getByteAt(oFile, iStart + i) == 2 && getByteAt(oFile, iStart + i + 1) == 120) { var caption = getString2At(oFile, iStart + i + 2, 800); } if (getByteAt(oFile, iStart + i) == 2 && getByteAt(oFile, iStart + i + 1) == 80) { var credit = getString2At(oFile, iStart + i + 2, 300); } } exif['ImageDescription'] = caption; exif['Artist'] = credit; return exif; }

So let me now modify my question slightly. How can the function above be improved?

36404693 0 Get latest version of table using hive union-all operator

I have versioned hive tables containing metrics partitioned by date that I want to join with other versioned hive tables containing different (but related) metrics also partitioned by date. For example:

Table A_v1 (exists for day 1) | col1 | col2 | | a1 | b1 | | a2 | b2 | Table A_v2 (exists for day 2, represents metrics derivation algorithm change) | col1 | col2 | | a3 | b3 | | a4 | b4 | Table B_v1 (exists for both day 1 and day 2) | col3 | col4 | | a1 | c1 | | a2 | c2 | | a3 | c3 | | a4 | c4 |

I know I can use the UNION ALL Hive operator to basically concatenate tables A_v1 and A_v2. What I would like to do however is write something like

select a.col1, a.col2, b.col4 from union(A_v1, A_v2) a, B_v1 b where a.col1=b.col3

I know the above syntax is wrong (intended only as a pseudo-code query) but is there some way of accomplishing the same thing in Hive?

The image you've shown is probably a UISegmentedControl. That's how you tap something so that it stays selected (and other choices are deselected). It's easy to customize a segmented control so that the background image is different when a segment is selected vs. when it is not.

If your compiler supports C++ 2011 then you can write the following way providing that letters will be listed in the order in which they are present in the string

#include <iostream> #include <string> #include <map> int main() { std::string s( "slowly" ); auto comp = [&]( char c1, char c2 ) { return s.find( c1 ) < s.find( c2 ); }; std::map<char, int, decltype( comp )> m( comp ); for ( char c : s ) ++m[c]; for ( auto p : m ) std::cout << p.first << ": " << p.second << std::endl; }

The program output is

s: 1 l: 2 o: 1 w: 1 y: 1

Otherwise if the compiler does not support C++ 2011 then instead of the lambda you have to use a function class defined before main. Also youi should substitute the range-based for loop for an ordinary loop.

You can store the values in MySQL as INT UNSIGNED which occupies 4 bytes (i.e. 32 bits).

To insert the values into the database, you must use sprintf() with %u format on 32 bit machines:

$hash = crc32("The quick brown fox jumped over the lazy dog."); $stmt = $db->prepare('INSERT INTO mytable VALUES (:hash)'); $stmt->execute(array( ':hash' => sprintf('%u', $hash), ));

Update

You could also make sure that you're always working with int32 types (signed long) on both 32 and 64-bit platforms. Currently, you can only accomplish this by using pack() and unpack():

echo current(unpack('l', pack('l', $hash))); // returns -2103228862 on both 32-bit and 64-bit platforms

The idea for this was contributed by mindplay.dk

40314237 0 Progress Bar with Ajax JQuery and PHP for import a .csv file to MySQL

I tried to write a code for a progress bar using PHP, JQuery and HTML. So, I made a Ajax Request for a PHP file and in the success Ajax parameter I search a data requested from PHP File like this..

success: function(data){ if(data == 'Error1'){ alert("The File is not a .csv"); }else if(data == "Error2"){ alert("Please select a file to import!"); }else{ $('#consumidor_table').html(data); alert("The importation has been made!"); } }

That else does print a Table with MySql DB lines. The PHP file read a .csv from a HTML input and insert those lines in DB.

Actually, my code to do a progress bar is it: Before at success parameter

xhr: function(){ var xhr = new window.XMLHttpRequest(); xhr.upload.addEventListener("progress", function(evt){ if (evt.lengthComputable) { var percentComplete = evt.loaded / evt.total; console.log(evt.loaded); console.log(evt.total); console.log(percentComplete*100); addProgress(percentComplete*100); } }); return xhr; },

The entire codes: JQuery; PHP URL

The Error: When a upload a file and submit the form, the console.log(evt.total); and console.log(evt.loaded); print the same value, and them the progress bar is fully, but the Ajax continues requesting the PHP file and my table is empty yet.

So what I can do to my progress bar work with the response from PHP file?

In Autofac you use Modules for this purpose. Groups of related components are encapsulated in a module, which is configured by the programmatic API.

Autofac's XML configuration has support for modules, so once you've decided to use one in an applicaiton, you can register the module (rather than all the components it contains) in the config file.

Modules support parameters that can be forwarded to the components inside, e.g. connection strings, URIs, etc.

The documentation here should get you started: http://code.google.com/p/autofac/wiki/StructuringWithModules

This isn't an answer but it is too long for a comment: sorry.

There are three possibilities for creating variable bindings that seem to be common:

variables are explicitly bound at the start of a scope;
there is a construct which creates a binding which can occur anywhere in a scope, but it's not just assignment;
variables get implicitly bound in a surrounding scope on their first assignment.

An example of (3) is Python. Languages which do this end up needing explicit scope-resolution operators (global and now nonlocal in Python) to deal with the stupid, lazy, pun they have done and are not worth discussing further: you need binding constructs which are distinct from assignment or you end up living in pain for ever.

Common Lisp is an example of (1), and C used to be: they are both (C was) examples of languages where all the bindings needed to be created at the start of a scope construct.

Within (1) there are languages which have some kind of block construct ({ ... } in C) which can be used for grouping and for scope, and ones which have a grouping construct and one or more separate scoping constructs: CL is in the latter family.

So in (old) C you would say

{ int i = 3; ... }

While in CL you say

(let ((i 3)) ...)

-- the scope construct here is let (and there are others of course).

Of course, CL, being a Lisp, can perfectly happily invent a construct which looks like C's blocks:

(defmacro scope (&body vars/body) (loop for (var? . body?) on vars/body while (and (listp var?) (<= 2 (length var?) 3) (eql (first var?) 'var) (symbolp (second var?))) collect (case (length var?) (2 (second var?)) (3 (rest var?))) into bindings finally (return `(let* ,bindings ,var? ,@body?))))

And now

(scope (var a) (var b 2) ...)

is a construct in the language.

So really these two variants on (1) are more similar than they are different: it's just a matter of how you cut up the underlying constructs you want in the language: C conflated scope blocks and grouping, CL doesn't.

(2) is different however. Here you are allowed to intermingle binding constructs and other things within a scope construct. C is now like this, and so is JavaScript. CL is not like this natively (obviously, being a Lisp, it could become like this with some macrology, although that macrology would be a lot hairier than what I wrote above).

In such a language you really need a separate binding-creation construct, because it can't be part of the scoping construct. Languages like C already treat the binding-creation construct as separate, so for them it's just a matter of relaxing the rule which says bindings must all be created at the start of a scope construct.

Languages like this have a significant question to answer though: what is the scope of a binding? Does something like

{ ... int x = 3; ... }

Really mean

{ ... { int x = 3; ... } }

or does it mean

{ int x; ... x = 3; ... }

The latter case is easier, but means that there's an awkward region where references to x are legal but its value may not be well-defined. C takes the former interpretation I think.

This is mostly fine for languages like C where the grouping construct is the same as the scoping construct. But it's not fine for languages like JavaScript where the grouping construct is not the scoping construct and, worse, where there is no scoping construct other than functions (or used not to be). And in fact languages like that can't really fix the problem, since there's no useful scoping construct. Well, of course, they fix it by growing a scoping construct.

Note that although CL is a (1) language there are Lisp-family languages which are (2) languages: in particular Racket is. In Racket (but not, I think, in Scheme) you can say

(define (foo) (define bar 1) ;; is baz bound here? (display bar) (define baz 3) (list bar baz))

And the answer is that yes, baz is bound there, but it's bound to an undefined object and you'll get an error (at run time, not compile time) if you try to use it. So this is a run-time error:

(define (foo) (define bar 1) (display baz) (define baz 3) (list bar baz))

while this

(define (foo) (define bar 1) (display baz) (let () (define baz 3) (list bar baz)))

is a compile time error. (I am actually slightly confused about which constructs in Racket create scopes.)

Process Initiated from device : now you have coordinates now in you application so what you can do on launching of a web make an AsyncTask to hit the webservice passing these longitude and latitude and get the corresponding message as response.

Process Initiated from server: for that you need to implement a GCM push functionality in your application what server needs to do it will push a message to device and after getting the push do the same thing as mentioned in process initiated from device.

By "loaded by the browser" I mean, are these images loaded immediately by the browser so that they are available right away when the image is no longer displayed as none using css. Will it be taken from cache or loaded anew the moment it is no longer displayed as none?

27722123 0 Laravel Validation (unique rule)

i use a seperate class for validation so it looks like

class UserValidation { protected static $id; protected static $rules = [ 'email' => 'required|email|unique:users,email,{{ self::$id }}', 'password' => 'required|alpha_dash|min:4', ]; public static function validate($input, $id) { self::$id = $id; return Validator::make($input, self::$rules); } }

so imagine a user wants to update only his password ,so he updates it > submit but then he receive the error this email is already taken ,because laravel cant read {{ self::$id }} ,so how do i solve something like that.

So finally got the system up and running, and for all the people facing similar problems, and without munch knowledge of unicorn or ngixn here are the steps:

First make sure both services are running (unicorn is the app server and ngixn is the http server), both services should be configured in /etc/init.d/.

Stop both services.

Check your policies in selinux, here is a good question on how to do it for the same error in PHP nginx error connect to php5-fpm.sock failed (13: Permission denied), the idea is to be sure selinux ins't interfering with the rad process of the socket (the socket is created by unicorn and readed by ngixn)

then you have to edit your config files unicorn.rb and nginx.conf, both should point to a folder different to tmp for the socket here is why http://serverfault.com/questions/463993/nginx-unix-domain-socket-error/464025#464025

So finally my configurations looks like this:

Part of nginx config file

upstream unicorn { server unix:/home/myuser/apps/myapp/shared/socket/unicorn.camicase.sock fail_timeout=0; }

part of unicorn config file

listen "/home/deployer/apps/stickystreet/shared/socket/unicorn.camicase.sock"

then start unicorn a ngixn, if you get a (13: Permission denied) while connecting to upstream error just do a sudo chmod 775 socket/ changing the socket for whatever folder you put your unicorn socket to be stored, the restart ngixn service.

38025102 0 how to make ssis map columns based order instead of column names

I am working on a project where there are 700 columns in a remote server and our destination table have columns that starts with underscore for example if there is a "SchoolName" column in the remote server, on our destination table we would have "_SchoolName" or "_School_Name" column. We use to use DTS package to import data "which doesn't use column name to map, instead it uses the order of the column on the select statement to map the column in the destination table". Now we would like upgrading our DTS package to SSIS, but mapping 700 columns manually has been a nightmare. Is there any way we can map columns based on the column orders instead of column name?

In symfony, you only have to persist a new entity. If you update an existing entity found by your entity manager and then flush, your entity will be updated in database even if you didn't persist it.

Edit : you can detach an entity from the entity manager before flushing it using this line of code :

$em->detach($formModelEntity);

Based on the description of what you are doing, I don't understand why you think your query works.

The overlap query should look like this:

SELECT AssetID as UnAvailableAsset FROM agreementasset WHERE CheckOutDate <= @RentEndDate AND ExpectedReturnDate >= @RentStartDate;

This type of query can be difficult to optimize (in most databases). You can start with an index on agreementasset(CheckOutDate, ExpectedReturnDate, AssetID).

An other solution that may not appeal to some but is fast to implement and works well is to introduce a new property on the object for sorting purposes. Make the new property contain a sorting character as the first character (a number works well) and the actual sorting value as the rest of the characters. Implement some easy if-else statements to set the appropriate value of the sorting property.

When adding this column to the grid just make it hidden and sort on that column.

Possibly a less elegant solution than the one proposed by najmeddine, but it works.

This works for removing a certain color from a bitmap. The main part is the use of AvoidXfermode. It should also work if trying to change one color to another color.

I should add that this answers the question title of removing a color from a bitmap. The specific question is probably better solved using PorterDuff Xfermode like the OP said.

// start with a Bitmap bmp // make a mutable copy and a canvas from this mutable bitmap Bitmap mb = bmp.copy(Bitmap.Config.ARGB_8888, true); Canvas c = new Canvas(mb); // get the int for the colour which needs to be removed Paint p = new Paint(); p.setARGB(255, 255, 0, 0); // ARGB for the color, in this case red int removeColor = p.getColor(); // store this color's int for later use // Next, set the alpha of the paint to transparent so the color can be removed. // This could also be non-transparent and be used to turn one color into another color p.setAlpha(0); // then, set the Xfermode of the pain to AvoidXfermode // removeColor is the color that will be replaced with the pain't color // 0 is the tolerance (in this case, only the color to be removed is targetted) // Mode.TARGET means pixels with color the same as removeColor are drawn on p.setXfermode(new AvoidXfermode(removeColor, 0, AvoidXfermode.Mode.TARGET)); // draw transparent on the "brown" pixels c.drawPaint(p); // mb should now have transparent pixels where they were red before

If the sample is representative of the page, the the form "myForm" doesn't exist when the script is evaluated. In addition to using document.getElementById (or document.forms.formName), you'll need to delay setting var myForm until after the form element is processed or, better yet, pass the form as an argument to the functions rather than using a global variable.

Your select is not doing what you think it does.

The most compact version in PostgreSQL would be something like this:

with data(first_name, last_name, uid) as ( values ( 'John', 'Doe', '3sldkjfksjd'), ( 'Jane', 'Doe', 'adslkejkdsjfds') ) insert into users (first_name, last_name, uid) select d.first_name, d.last_name, d.uid from data d where not exists (select 1 from users u2 where u2.uid = d.uid;

Which is pretty much equivalent to:

insert into users (first_name, last_name, uid) select d.first_name, d.last_name, d.uid from ( select 'John' as first_name, 'Doe' as last_name, '3sldkjfksjd' as uid union all select 'Jane', 'Doe', 'adslkejkdsjfds' ) as d where not exists (select 1 from users u2 where u2.uid = d.uid;

It looks as if you want to use Express and the express.compress middleware. That will figure out if a browser supports gzip and/or deflate, so you don't have to.

A simple setup could look like this:

var express = require('express'); var app = express(); app.use(express.compress()); app.get('/', function(req, res) { res.send({ app_id: 'A3000990' }); }); app.listen(3000);

If your data is a JSON-string, you have to set the correct content-type header yourself:

res.setHeader('Content-Type', 'application/json'); res.send(data);

Since you are using sh, and not bash, you should use a single equal = to do the string comparison, instead of the double equal ==. Also it is a good practice to double quote the variable in test statement (this error is not caused by incorrect quoting though).

The comparison should be:

if [ "$1" = "--daily" ]

and

elif [ "$1" = "--monthly" ]

Most of the configuring/querying can be done via SNMP, so you don't have to have a SSH client/command parser built in you application. What's supported depends on router/ios version. You can check here: SNMP OID Browser. SNMP can sometimes be overwhelming, but in time it can be of great use to you. My first suggestion is to find a SNMP browser (eg. from solarwinds) so you can inspect what info you can get from the router. Then you can use NET-SNMP library to do the actual querying/configuring of the router, or if you are willing to pay you can try IP*Works.

Completely new answer as of given details. You are working with VBA so you can call WorksheetFunctions like

Dim someVariable someVariable = WorksheetFunction.Quotient(Worksheets("Sheet1").Cells(1, "A").Value, Worksheets("Sheet1").Cells(1, "B").Value) Debug.Print someVariable

There is a quite good list of supported functions available on MSDN WorksheetFunction. Please choose your current Excel version on the linked page.

Furthermore I found another very important site concerning your problem that states that not all WorksheetFunctions are supported as Application. (see support.microsoft.com)

So I searched for workarounds and found a quite simple one on StackOverflow. But on the other hand - you really could make use of the VBA builtIn operator MOD

' created some variables, as I made some attempts on creating a good example Dim value1 value1 = Worksheets("Sheet1").Cells(1, "A").Value Dim value2 value2 = Worksheets("Sheet1").Cells(1, "B").Value someVariable = value1 Mod value2 Debug.Print someVariable ' of course you may use a single line statement too someVariable = Worksheets("Tabelle1").Cells(1, "A").Value Mod Worksheets("Tabelle1").Cells(1, "B").Value

I think there are some pretty good links to have a deeper look into.

3651525 0 Querying documents containing two tags with CouchDB?

Consider the following documents in a CouchDB:

{ "name":"Foo1", "tags":["tag1", "tag2", "tag3"], "otherTags":["otherTag1", "otherTag2"] } { "name":"Foo2", "tags":["tag2", "tag3", "tag4"], "otherTags":["otherTag2", "otherTag3"] } { "name":"Foo3", "tags":["tag3", "tag4", "tag5"], "otherTags":["otherTag3", "otherTag4"] }

I'd like to query all documents that contain ALL (not any!) tags given as the key.

For example, if I request using '["tag2", "tag3"]' I'd like to retrieve Foo1 and Foo2.

I'm currently doing this by querying by tag, first for "tag2", then for "tag3", creating the union manually afterwards.

This seems to be awfully inefficient and I assume that there must be a better way.

My second question - but they are quite related, I think - would be:

How would I query for all documents that contain "tag2" AND "tag3" AND "otherTag3"?

I hope a question like this hasn't been asked/answered before. I searched for it and didn't find one.

I would do this using ddply from plyr package. For example:

require(plyr) res <- lapply(list.files(pattern='^[1-2].txt'),function(ff){ ## you read the file data <- read.table(ff, header=T, quote="\"") ## remove the outlier data <- data[data$RT>200,] data <- ddply(data,.(Condition),function(x) x[!abs(scale(x$RT)) > 3,]) ## compute the mean ddply(data,.(Condition,Reqresponse,Score),summarise,RT=mean(RT)) }) [[1]] Condition Reqresponse Score RT 1 X a 0 500 2 X a 1 750 3 X b 0 500 4 X b 1 500 5 Y a 0 400 6 Y a 1 640 7 Y b 1 1000 8 Z a 0 1000 9 Z a 1 1675 10 Z b 0 400 [[2]] Condition Reqresponse Score RT 1 X a 0 500 2 X a 1 750 3 X b 0 500 4 X b 1 500 5 Y a 0 400 6 Y a 1 640 7 Y b 1 1000 8 Z a 0 1000 9 Z a 1 1675 10 Z b 0 400

You can reassign $this value by variable variable

$name = 'this'; $$name = 'stack'; echo $this; // this will result stack

I have used the above code for DropBox and it works well because it takes an array of objects but i cant find solution for OneDrive.com! Below documentation only shows how to upload a single file using URL. but i want to upload multiple files.

The Format From The OneDrive Site

var saverOptions = { file: "inputFile", fileName: 'file.txt', success: function(){ // upload is complete }, progress: function(p) { // upload is progressing }, cancel: function(){ // upload was cancelled }, error: function(e) { // an error occured } }

The difference is in what default encoding is used. From MSDN, we can see that Set-Content defaults to ASCII encoding, which is readable by most programs (but may not work if you're not writing english). The > output redirection operator on the other hand works with Powershell's internal string representation, which is .Net System.String, which is UTF-16 (reference)

As a side-note, you can also use Out-File, which uses unicode encoding.

37385987 0 GCM and swift can register and receive a success notification but no other push noteificiatons

Update: Ok so I redid all my certs and now I am getting this by testing the GCM at this site http://techzog.com/development/gcm-notification-test-tool-android/

 URL: http://android.googleapis.com/gcm/send Headers: Array ( [0] => Authorization: key=AIzaSyBPTQGXlyImFWPda1s2LVUKIN98uMS0Bac [1] => Content-Type: application/json ) 1 Fields: Array ( [registration_ids] => Array ( [0] => fBspb1tyYDg:APA91bE0-pzjJrJodW2JuNvnEZSkUaw0rBjf0gkwu2Yi9GaS8WcrhZII2LnDcclwd4K5W51osjxfBCM7E76Ck7EDG4YHEESAesXZBgrSrHDQNAjGPv1VgOi-zkFi1biZSQzeaEbS3xch ) [data] => Array ( [message] => Koimute [] => ) ) 1 Result: Unauthorized Error 401

So this means that it is being basically stopped from getting to the phone I think.

UPDATE: Ok so I have been working at it and have tried to change the cert around and fool with the settings. now my console is printing out that I am connected to the GCM. But, still I do not receive any notification from the server at all. Here is what my console is printing

0028-05-24 12:21:32.829: GCM | GCM library version 1.1.4 0028-05-24 12:21:32.841: GCM | Invalid key in checkin plist: GMSInstanceIDDeviceDataVersion 2016-05-24 12:21:32.856 MyApp[560:] <GMR/INFO> App measurement v.2003000 started 2016-05-24 12:21:32.857 MuApp[560:] <GMR/INFO> To enable debug logging set the following application argument: -GMRDebugEnabled 0028-05-24 12:21:32.920: GCM | Invalid key in checkin plist: GMSInstanceIDDeviceDataVersion 2016-05-24 12:21:33.053 MyApp[560:106171] INFO: GoogleAnalytics 3.14 -[GAIReachabilityChecker reachabilityFlagsChanged:] (GAIReachabilityChecker.m:159): Reachability flags update: 0X000002 Registration Token: My token i get from GCM 2016-05-24 12:21:33.067 MyApp[560:] <GMR/INFO> App measurement enabled Connected to GCM 2016-05-24 12:21:33.937 MyApp[560:106213] INFO: GoogleAnalytics 3.14 -[GAIBatchingDispatcher hitsForDispatch] (GAIBatchingDispatcher.m:368): No pending hits.

The GCM | Invalid key in checkin plist: GMSInstanceIDDeviceDataVersion error from what I gathered means that it is working and is fine. They said that they will fix this in a later release

OLD: So I have set up the GCM as well as a Google Analytics in my iOS project. The Analytics works perfect and all. Thats why I don't think its my Google service json that is the problem. I can successfully register to receive a token from the GCM server. But when I try to send a push notification nothing happens. I do receive a notification when it registers successfully so I think that my notification centre is working too. I follows the steps for creating the certificates as well. So I do not know where the problem is.: I am also using a third party APNs tester to rule out my server being the issues. I am using APN Tester. The APN tester returns this from doing a push notification:

36131248 0 tfs unable to browse projects

I'm using Visual Studio Team Services (was TFS Online) server {MyProject}.visualstudio.com. I'm able to connect to the server, map the project, even receive a review request, but I can't see my team projects under DefaultCollection. Currently when I'm opening the Source Control Explorer I'm only seeing {MyProject}.visualstudio.com\DefaultCollection underlying projects are missing, but my user is in project team members list.

What I missed, what I should do else to be able to browse my projects, get and work with them?

Note: My account was not a microsoft account. I received an email to join the visual studio after tfs administrator added my email as the project team member. I follow to the link and I create a new account during VS sign up using that email and then successfully signed in.

Thanks a lot

36022303 0 Error when publishing from VS 2015 - The components for communicating with FTP servers are not installed

I'm using Visual Studio 2015 Enterprise with Update 1. I have a single solution, with a single ASP.NET web application project. I publish it by right-clicking on the project node, and clicking "Publish". I've setup a publish profile for FTP. Credentials work/tested/etc. Server connectivity is good.

However, when publish from Visual Studio 2015, it says "The components for communicating with FTP servers are not installed."

Things I've tried: - Validating FTP server name and credentials. - Clean/Rebuild - Restarting Visual Studio. - Kicking it (hard).

Things I did not try: - Restarting PC. - Repairing Visual Studio. - Sacrificing a goat.

I do NOT have Xamarin installed, but I do have Tools for Apache Cordova. I do NOT have VS 2013 (or any prior version) of VS installed.

You shouldn't need to destroy and create the annotation every time. Once it has been created, just update the anchorPoint. Removing and adding the annotation is probably related to the constant redraw.

Here's my solution to make it a little more generic:

private static final String[] magnitudes = new String[] {"", "K", "M"}; public static String shortenNumber(final Integer num) { if (num == null || num == 0) return "0"; float res = num; int i = 0; for (; i < magnitudes.length; i++) { final float sm = res / 1000; if (sm < 1) break; res = sm; } // don't use fractions if we don't have to return ( (res % (int) res < 0.1) ? String.format("%d", (int)res) : String.format("%.1f", res) ) + magnitudes[i]; }

24883358 0 How to Add custom markers to a google directions map at the start only of multiple journeys

Firstly let me say I am not a Java or even web developer. I have pieced together this code via the web and am almost at the finish point - but cannot get over the line.

I am mapping journeys for a trucking firm, and want to use a custom marker at the start of each journey, with no marker at the end of the journey. The attached code does all I need for mapping the journey but I can't get the markers to render on the page. What am I missing?

I believe there is no way to make it compile. You will have to use reflection to make the call.

Actually. You could cheat if you contain it within a class:

 public class Container<T> { public Container(T value) { Value = value; } public T Value { get; private set; } } public void Bar<T>(T item) { this.Foo<Container<T>>(new Container<T>(item)); }

but this adds one layer you need to call-through and makes the types less clear.

Your FOR loop: since JS uses zero-based arrays, you can't have <=, otherwise it will look for an index one higher than what you have. Use < instead;
I moved your validation for whether any fields were checked outside the loop to make management easier. It's cleaner this way than worrying about breakout out of loops in the middle of them.

Here:

function isNull() { var isChecked = false; var radiobutton = document.getElementsByName('radiobtn'); for (var i=0; i < radiobutton.length; i++) { if (radiobutton[i].checked) { isChecked = true; } } if ( !isChecked ) { alert("Make a selection."); return false; } }

I don't know how your form tag looks, but here is what you need to prevent the form from submitting if no radio fields are checked:

<form action="" method="post" onSubmit="return isNull();">

You should look in the default_master.properties file (in my case it's in the same directory as js-export) and change the database properties according to your setup.

Then js-export and js-import should work.

21975826 0 Split a string with using preg_split()

I have a sting that is in this format.

<span class="amount">$25</span>–<span class="amount">$100</span>

What I need to do is split that into two strings. The string will remain in the same format but the prices will change. I tried using str_split() but because the price changes I wouldn't be able to always know how many characters to split the string at.

What I am trying to get is something like this.

String 1

<span class="amount">$25</span>–

String 2

<span class="amount">$100</span>

It seems the best option I have found is to use preg_split() but I don't know anything about regex so I'm not sure how to format the expression. There may also be a better way to handle this and I just don't know of it.

Could someone please help me format the regex, or let me know of a better way to split that string.

Edit

Thanks to @rm-vanda for helping me figure out that I don't need to use preg_split for this. I was able to split the string using explode(). The issue I was having was because the '-' was encoded weird and therefore not returning correctly.

"Determine whether a variable is considered to be empty. A variable is considered empty if it does not exist or if its value equals FALSE. empty() does not generate a warning if the variable does not exist."

Returns FALSE if var exists and has a non-empty, non-zero value. Otherwise returns TRUE.

The following things are considered to be empty:

"" (an empty string)

0 (0 as an integer)

0.0 (0 as a float)

"0" (0 as a string)

NULL

FALSE

array() (an empty array)

$var; (a variable declared, but without a value)

27446413 0 SVG path animation issue

I'm new to CSS animations and I'm struggling to get this animation working.

I've been following this CSS Tricks post.

Currently I don't understand why there are three separate starting point in the animation.

I would like to start from one point, follow the path all the way(doesn't matter which direction) and close the animation at the starting point.

Is that possible? If it is, can anyone tell what's wrong in what I've tried so far?

Any help appreciated, thanks.

According to the documentation of Boost shared_ptr, the shared_ptr constructor is marked explicit, meaning that there's no implicit conversion from T*s to shared_ptr<T>. Consequently, when you're trying to insert the iterator range defining your old container into the new container, the compiler complains because there's no way of implicitly converting from the raw pointers of the old containers into the shared_ptrs of the new container. You can fix this by either using a back_inserter and transform, or by just doing the iteration by hand to wrap each pointer and insert it one at a time.

It turns out that there's a good reason that you don't want this conversion to work implicitly. Consider:

void DoSomething(shared_ptr<T> ptr) { /* ... */ } T* ptr = new T(); DoSomething(ptr);

If the implicit conversion were allowed here, then the call to DoSomething would be legal. However, this would cause a new shared_ptr to start referencing the resource held by ptr. This is problematic, because when this shared_ptr goes out of scope when DoSomething returns, it will see that it's the only shared_ptr to the resource and will deallocate it. In other words, calling DoSomething with a raw pointer would implicitly delete the pointer!

20521383 0 Updating MySQL database with values from dynamically generated textboxes in different divs

I'll try my best to explain my problem here, forgive me if I use the wrong terms occasionally, I'm still pretty much a beginner, and quite terrible at explaining.

My goal is to use Jquery to dynamically add textboxes, and then use C# to update the values in those textboxes into a mysql database.

The database consists of four columns, UserID(PK), Date(PK), Subject(PK) and Hours. The goal is to be able to fill in the amount of hours you've worked on a subject on certain day of the current week.

So far, I'm able to add a new textbox whenever I press the button for the day I want to update the data for. The problem I'm running into is that I have no idea how to build the mysql query in such a way that it correctly associates the entered values with the day they're entered for.

My code so far:

<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.2.min.js"></script> <script type="text/javascript"> </script> <title></title> </head> <body> <form id="form1" runat="server"> <div id="dag1" runat="server"> <input class="btnAdd" type="button" value="Monday" onclick="AddTextBox($(this).parent().attr('id'));" /> </div> <div id="dag2" runat="server"> <input class="btnAdd" type="button" value="Tuesday" onclick="AddTextBox($(this).parent().attr('id'));" /> </div> <div id="dag3" runat="server"> <input class="btnAdd" type="button" value="Wednesday" onclick="AddTextBox($(this).parent().attr('id'));" /> </div> <div id="dag4" runat="server"> <input class="btnAdd" type="button" value="Thursday" onclick="AddTextBox($(this).parent().attr('id'));" /> </div> <div id="dag5" runat="server"> <input class="btnAdd" type="button" value="Friday" onclick="AddTextBox($(this).parent().attr('id'));" /> </div> <br /> <br /> <div id="TextBoxContainer"> <script type="text/javascript"> function AddTextBox(day) { var value = "" var div = document.createElement('DIV'); div.innerHTML = '<input name = "Subject" type="text" value = "' + value + '" /><input name = "Hours" type="text" value = "' + value + '" />'; document.getElementById(day).appendChild(div); } </script> </div> <br /> <asp:Button ID="btnPost" runat="server" Text="Post" OnClick="Post" /> <asp:Label ID="labeltest" Text="" runat="server" /> </form> </body> </html>

And my codebehind:

 protected string Values; protected void Post(object sender, EventArgs e) { string[] textboxValues = Request.Form.GetValues("Subject"); string[] textboxValues2 = Request.Form.GetValues("Hours"); MySqlConnection conn; MySqlCommand comm; string myConnectionString = "server=localhost;uid=root;database=caroussel"; using (conn = new MySqlConnection()) { try { int veld = 0; foreach (string val in textboxValues) { string value2 = textboxValues2[veld]; veld++; using (comm = new MySqlCommand("update uren set Subject=@Subject, Hours=@Hours WHERE Date=??? AND UserID=1, conn)) ; comm.Parameters.Add("@Subject", MySqlDbType.VarChar, 45); comm.Parameters["@Subject"].Value = val; comm.Parameters.Add("@Hours", MySqlDbType.Int16); comm.Parameters["@Hours"].Value = value2; comm.Parameters.Add("@UserID", MySqlDbType.Int16); comm.Parameters["@UserID"].Value = 1; comm.Parameters.Add("@Date", MySqlDbType.VarChar, 45); comm.Parameters["@Date"].Value = ????; { conn.ConnectionString = myConnectionString; conn.Open(); comm.ExecuteNonQuery(); conn.Close(); } } } finally { conn.Close(); } } }

If there's anything missing, or clarification is required, or I simply forgot something, please do tell, I'm rather stuck at the moment, and I haven't been able to find something that would help me so far.

6191772 0 Calling C/C++ functions in dynamic and static libraries in D

I'm having trouble wrapping my head around how to interface with C/C++ libraries, both static (.lib/.a) and dynamic (.dll/.so), in D. From what I understand, it's possible to tell the DMD compiler to link with .lib files, and that you can convert .dll files to .lib with the implib tool that Digital Mars provides. In addition, I've come across this page, which implies being able to call functions in .dlls by converting C header files to D interface files. Are both of these methods equivalent? Would these same methods work for Unix library files? Also, how would one reference functions, enums, etc from these libraries, and how would one tell their D compiler to link with these libs (I'm using VisualD, specifically)? If anyone could provide some examples of referencing .lib, .dll, .a, and .so files from D code, I'd be most grateful.

Sorry cordova application works at your device. It does not operate at your network switch/router. There is yet no way that your device could ask your router if it has working internet access and the router could acknowledge that yes i have or not. What you could do at your device only to detect network access.

The only other thing you can do is send an http request to something like google which is almost never down, in device ready event or when required, if it responds with ready state then your internet is ok and otherwise not.

A function to test this address to check if the device has access to internet would look like this :

function testInternet(win,fail){ $.get("https://people.googleapis.com/v1/people/me/connections").done(win).fail(fail); } Or , function testInternet(win,fail){ $.ajax({ url:"https://people.googleapis.com/v1/people/me/connections", timeout:5000, //timeout to 5s type: "GET", cache: false }).done(win).fail(fail); }

ajax request response back 401 (Unauthorized) which means we have internet access but we are Unauthorized for that google api. here is the google api

The plugin does not detect if the user has access to the Internet, but only if the user is on a network. Since your phone is on a WiFi network even though the WiFi network doesn't have access to the Internet, the plugin is performing as designed.

primarykey fields ( of any data-type ) are not included in the list returned by allFileds method of the Mapper.

You can prepend the field separately if you want

something like

 var myMapperPrimaryKey=DummyMapper.primaryKeyField var fieldList=DummyMapper.allFields.toBuffer[BaseField] fieldList.prepend(myMapperPrimaryKey) // Now fieldList is having the primaryKey along with other fields.

I am assuming the following format:

word definitionkey : definitionvalue [definitionkey : definitionvalue …]

None of those elements may contain a space and they are always delimited by a single space.

The following code should work:

awk '{ for (i=2; i<=NF; i+=3) print $1, $i, $(i+1), $(i+2) }' file

Explanation (this is the same code but with comments and more spaces):

awk ' # match any line { # iterate over each "key : value" for (i=2; i<=NF; i+=3) print $1, $i, $(i+1), $(i+2) # prints each "word key : value" } ' file

awk has some tricks that you may not be familiar with. It works on a line-by-line basis. Each stanza has an optional conditional before it (awk 'NF >=4 {…}' would make sense here since we'll have an error given fewer than four fields). NF is the number of fields and a dollar sign ($) indicates we want the value of the given field, so $1 is the value of the first field, $NF is the value of the last field, and $(i+1) is the value of the third field (assuming i=2). print will default to using spaces between its arguments and adds a line break at the end (otherwise, we'd need printf "%s %s %s %s\n", $1, $i, $(i+1), $(i+2), which is a bit harder to read).

1861282 0 .net, UserControls, and application start time

We have a medium sized application that depends on several usercontrols, namely:

A tablelayout panel, with 2x5 grid of usercontrols, with 3+ levels of inheritance. A big issue we're running into with our application has proven to be startup time (both cold\warm), one of the big big hangups we're getting is initializing this usercontrol grid.

From our timing reports, this form comes in at about 0.75 seconds for initialization, and cutting this down would be a big deal.

My question is: What the heck can I do to speed this up? Whenever I run timing checks on similar-complexity InitializeComponents (all windows, .net controls), the result is magnitudes less (<10 milleseconds) sometimes.

edit) I'm wondering if things like marking my final classes sealed or something similar would help.

edit2) I've looked deeper into the timing of initializecomponent, and for my current machine, The main container adds 10 components to it (at 10ms a piece). Each of those components adds 3 components (at 10ms a piece). 10x10 + 30x10 = 700ms. Unless I can increase the speed at which items get added to their containers, I think I'm SOL.

22589182 0 Set 'nice' value to concrete processes, by default

I would like to set specific "nice" values to several processes in a laptop. For example, I would like the window manager to run at -10, and keep the default at 0.

I know that "renice" can change the niceness of a processes, but this is a-posteriori, and I do not want to "renice" my window manager process every time that I open the computer. Similarly, "limits.conf" allows to specify default niceness for specific users or groups, but not (as far as I know) specific processes.

So my question is whether there is a way to define niceness for concrete processes, without having to change the default for the user and without having to renice the process once it runs.

styled this way:-

The problem is that when you set a 100% height value it take the longitud from the parent container. If the conatiner is the body tag it ajustment to the size of the content it self that could be very samll. You need to set up the size to a specifycally size you can use the window size for example.

You are using JSON.Stringify; it should be JSON.stringify. Did you check your console for errors? Simply spitting the JSON out isn't too user-friendly, though. Is that what you want?

You're going to have to iterate over each individual skill and then insert that into the table in a format that you see fit (perhaps you can use an un-ordered list):

var $table = jQuery("table"); $table.append(jQuery("tr") .append( jQuery("th").text("First Name")) .append( jQuery("th").text("LastName")) ... //and so on ) for(var i = 0; i < data.length; i++) { var $tr = jQuery("tr"); $tr.append( jQuery("td").text(data[i].firstname}) ).append( jQuery("td").text(data[i].lastname) )... var skills = data[i].skills; var $ul = jQuery("ul"); for(var j = 0; j < skills.length; j++) { var skill = skills[j]; $ul.append(jQuery("li").text(skill.name)); } $tr.append(jQuery("td").append($ul)); }

This should be very easy. Valid function names can only consist of alphanumerics, parenthesis, and possibly parameter values within the parens (i don't know enough javascript to know whether parameters are defined in the function call) and must start with a letter, correct? Therefore to validate that a string is a valid function name. Therefore this should work:

[a-xA-z]+[a-zA-z0-9_]\*(\\(.*?\\))\*

The developer doesn't own the tabBar, the framework does. It will fight you to make sure that the tabBar stays the same height. If you want to work around this, you can make your own toolbar and add autlayout constraints to its height to force it to stay whatever height you'd like.

8088427 0 Programatically rendering a web UserControl

I have a load of UserControl objects (ascx files) in their own little project. I then reference this project in two projects: The REST API (which is a class library project) and the main website.

I'm sure this would be easy in the website, simply use Controls.Add in any Panel or ASP.NET control would work.

However, what about the API? Is there any way I can render the HTML of this control, simply by knowing the type of the control? The RenderControl method doesn't write any HTML to the writer as the control's life cycle hasn't even started.

Please bare in mind that I don't have the controls in the web project, so I don't have a virtual path to the ascx file. So the LoadControl method won't work here.

All the controls actually derive from the same base control. Is there anything I can do from within this base class that will allow me to load the control from a completely new instance?

We are using Hudson with git. We have a build/test server which compiles our project and then a QA server to which we need to deploy.

We want to get the current built git commit sha and use it to pull the appropriate commit for deployment on our QA server.

Unfortunately it seems that the hudon git plugin does not set the git commit sha in the environment variables (as the svn plugin does in SVN_REVISION for example). How do we get around this?

Pointer/ examples will be helpful as I am a hudson noob.

I just encountered this issue in CE v1.9.0.1. My admin module was getting all processes as a collection and looping through each one calling reindexEverything(). I based the code on the adminhtml process controller which was working fine, but my code wasn't working at all.

I finally figured out the issue was that I had previously set the reindex mode to manual (to speed up my product import routine) as follows:

$processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); $processes->walk('setMode', array(Mage_Index_Model_Process::MODE_MANUAL)); // run product import $processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); foreach($processes as $p) { if($p->getIndexer()->isVisible()) { $p->reindexEverything(); //echo $p->getIndexer()->getName() . ' reindexed<br>'; } } $processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); $processes->walk('setMode', array(Mage_Index_Model_Process::MODE_REAL_TIME));

SOLUTION: set mode back to MODE_REAL_TIME before reindexing everything:

$processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); $processes->walk('setMode', array(Mage_Index_Model_Process::MODE_MANUAL)); // run product import $processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); $processes->walk('setMode', array(Mage_Index_Model_Process::MODE_REAL_TIME)); $processes = Mage::getSingleton('index/indexer')->getProcessesCollection(); foreach($processes as $p) { if($p->getIndexer()->isVisible()) { $p->reindexEverything(); //echo $p->getIndexer()->getName() . ' reindexed<br>'; } }

Note: these are snips from a few different methods hence the repeated assignment of $processes etc..

It seemed reindexEverything() wasn't doing anything when the processes index mode was set to MODE_MANUAL. Setting mode back to MODE_REAL_TIME and then calling reindexEverything worked fine.

I hope this helps someone as I had a few frustrated hours figuring this one out!

Thanks

8023571 0 What's wrong with this QuickSort program?

I've written a QuickSort algorithm based off pseudo-code that I had been given. I've been running through the outputs for about 4 hours now and I can't seem to find exactly why my algorithm starts to derail. This sort of collection logic is something I struggle with.

Anyway, whenever I run my program there's 3 possible results:

The list is organized and is 100% correct.
The list is 90% organized, one or two pairs of elements are off.
The list is never sorted and results in an infinite loop.

Given my results it leads me to believe that something has to do with the index variable I'm using. However, I can' figure out why or what's wrong with it.

Here's ALL of my code that I use for my QuickSort algorithm:

public void QuickSort(IList<int> list, int l, int r) { if (l>=r) return; int index = Partition(list, l, r); Console.WriteLine("index: " + index); QuickSort(list, l, (index-1)); QuickSort(list, (index+1), r); } public int Partition(IList<int> list, int l, int r) { int pivot = list[l]; int i = l; int j = r + 1; do { do { i++; } while(i < list.Count && list[i] < pivot); do { j--; } while(j > 0 && list[j] >= pivot); Swap(list, i, j); } while(i<j); Swap(list, i ,j); Swap(list, j, l); return j; } public void Swap(IList<int> list, int i, int j) { //Console.WriteLine("Swapping [i] " + list[i] + " with [j] " + list[j]); //PrintList(list, i, j, false); int temp = list[i]; list[i] = list[j]; list[j] = temp; //PrintList(list, j, i, true); }

PrintList is simply used to test my outputs.

Here is a sample input/output:

INPUT: [18,43,5,73,59,64,6,17,56,63]

OUTPUT: [5,6,18,17,43,59,56,63,64,73]

24658299 0 How to optimize a subset of JavaScript files created as RequireJS modules

I have single-page web application that uses RequireJS to organize and structure JavaScript code. Inside the app, I have some JS files that I want to optimize using r.js because they belong to an API that will be consumed by my customers. So, I just want to optimize those files and keep the rest of the code as it is now.

This is my application structure:

app
- main.js
- many other files and folders
scripts
- myAPI
  - app.js
  - many other files and folders
- require.js
- jquery.js
- build.js
index.htm

All the JavaScript code is located under the app and scripts folders. As I mentioned before, all those files are defined as RequireJS modules. This is how the main.js looks now:

require.config({ baseUrl: 'scripts', paths: { base: 'myAPI/base', proxy: 'myAPI/proxyObject', localization: 'myAPI/localization', app: '../app', } }); require(['myAPI/app'], function (app) { //app.init.... } );

As you can see, in the paths configuration I'm defining some aliases that point to myAPI (the folder I want to optimize).

This is how I reference RequireJS from the index.htm file:

<script data-main="app/main" src="scripts/require.js"></script>

This is the build file I created for r.js (scripts/build.js):

({ baseUrl: '.', out: 'build/myAPI.js', name: 'myAPI/app', include: ['some modules'], excludeShallow: ['some modules defined in the app folder'], mainConfigFile: '../app/main.js', optimize: 'uglify2', optimizeCss: 'none' })

The optimized file is generated, but I have some challenges trying to use it:

How do I reference that file from the app?
The dependencies to myAPI modules are broken now. RequireJS doesn't find the modules defined in myAPI.
What can I do to keep the aliases defined in require.config.paths working?

Could you please help me with some suggestions or feedback for this situation?

Thanks!!

as far as I can see you have a custom comparator (why does that keep a reference to the sorter? looks fishy) not a custom RowSorter.

The intended way to change sorting is to invoke toggleSortOrder(column) on RowSorter. For more fine-grained control you can need access to the DefaultRowSorter, f.i. its setSortKeys method.

This info on the changelog is more related to the fact that before the maximum number of concurrent sockets node could handle was set to 5 (it was changeable of course) but now it is set to Infinity by default.

This has nothing to do with the capacity of connexions an application can handle, that will be limited by the network's characteristics, the OS specifications, the available resources on the server, etc.

In short, you are looking at something (the blog post) that has nothing to do with your question.

In order to submit POST data, the data must be sent to the server. A hyperlink alone cannot do this - however with a bit of JS magic, you can easily accomplish this.

If you're using something like jQuery, you can capture the click event - gather data from the link based on the click event, and submit to the server via $.post/$.ajax.

HTML:

<a href="javascript:void(0);" class="age-less-then-five">age<5</a>

Javascript:

$('a.classname').click(function(){ var that = $(this), value = that.text().trim(); //you can optionally store a value in the classname, or ID which is what I would do.. in this scenario.. I think XD $.post('yoururl.com/phpscript.php',{postName: value}, function(data){ //load whatever data you want, or redirect to list.html now that you've gathered desired data } });

To clarify the above answer, var that = $(this); refers to the link that's been clicked on. So you could grab the class name from the anchor by: that.attr('class') // which would equal age-less-then-five or simply do as above, and grab the text inbetween the anchor tags by using .text(). We trim here, this really isn't the best way to do this.. but it is one way to do it. When I'm using a link to perform any sort of post to the server, I'll typically use an ID if it holds a unique value, or class name.

You are missing the .call() when you're trying to make an array copy from the HTMLCollection. Instead of this:

var x = document.getElementsByTagName("th"); var plop = Array.prototype.slice(x);

You can do this:

var x = document.getElementsByTagName("th"); var plop = Array.prototype.slice.call(x); console.log(plop);

Note: you don't need to make an array copy just to iterate over it. You can iterate an HTMLCollection directly:

var items = document.getElementsByTagName("th"); for (var i = 0; i < items.length; i++) { console.log(items[i]); }

Why in the view? Because the function is used for formatting, it doesn't actually return different data set.

my $newvar = $text =~ m/ quick (.*) dog /;

is an assignment in scalar context, and assigns either 1 or undef.

You want to make this assignment in list context

my ($newvar) = $text =~ m/ quick (.*) dog /;

which assigns the captured groups from the regular expression.

The difference between scalar and list contexts is one of the trickiest things to get used to in Perl.

Note that captured groups from regular expressions in Perl also get assigned to the special variables $1, $2, ... . So you also could just have said

print "$1\n";

Strings in python are declared using double or single quotes, therefore the variable data contains a string. You can check the type of a variable directly in python:

data = "000000000000000117c80378b8da0e33559b5997f2ad55e2f7d18ec1975b9717" type(data)

which outputs

str

meaning that the variable is a string. When you call the function decode('hex') on a string you obtain another string:

data.decode('hex') '\x00\x00\x00\x00\x00\x00\x00\x01\x17\xc8\x03x\xb8\xda\x0e3U\x9bY\x97\xf2\xadU\xe2\xf7\xd1\x8e\xc1\x97[\x97\x17'

Every character in your original string is interpreted as an hexadecimal number, and every pairs of hexadecimal numbers - e.s. "17" - is converted into an hexadecimal character using the escape sequence \x - becoming "\x17".

When you write "\x41" you are basically telling python to interpret 41 as a single ASCII character whose hexadecimal representation is 41.

The ASCII table contains the hexadecimal, decimal and octal values associated to the ascii characters.

If you try for example

"48454C4C4F".decode('hex')

you obtain the string "HELLO"

Lastly when you use [::-1] on a string you reverse it:

"48454C4C4F".decode('hex')[::-1]

produces the string "OLLEH"

You can find more about the escape characters reading the python documentation.

This works fine at getting whether the user has turned on or off their location services. An overlay is put on the screen informing the user they need to turn it on, if they have turned it off.

However the problem is after the user has set it, and then goes into settings -> location services and enabled it, I am unable to take the overlay off as I have know way off tracking in real time if it has been turned on or off.

Does anyone know how this can be achieved, cheers.

UPDATE:

This did the trick

var wrapperW = null; Titanium.Geolocation.addEventListener('location', function(e) { if (e.error) { //put overlay on wrapperW = overlays.GPSError($.win); } else { //keep updating Ti.API.info(e.coords); if (wrapperW != null) { wrapperW.hide(); } } });

Let me start with this: I don't think a Python script is the best tool for the job. If you want to do enterprise-level management of updates (e.g., for all machines on a network), then you should seriously consider using the existing MS tools.

With that said, here is how you might go about this:

Have a look at the windows-update tag on ServerFault, one of StackOverflow's sister sites: http://serverfault.com/questions/tagged/windows-update . A lot of the questions seem to cover command-line control of the update process. Keep in mind that the command line tools vary significantly between e.g. Windows XP on the one hand and Vista/7 on the other. With some luck, you should be able to use windows built-in commands rather than going to the windows update website programmatically.
Assuming you find the command-line incantations that you need: Use the subprocess module to call to the shell and execute those commands programmatically. Because you're using python, you may need to spend quite a bit of time parsing the command outputs to figure out how your shell calls are doing.

Hope that helps. I realize this is a rather high-level answer, but as it stands, the question is not very specific about what exactly you want to accomplish and why you're using python to do it.

16569984 0 Adding a fadeOut to tabs

I'd like to add a fadeout to the tabs on my page here, if someone could help with the javascript side?

Here's the html:

<ul class="tabs clearfix"> <li class="aboutustab active" style="border-left:1px solid #ccc;"><div class="up"></div>About</li> <li class="maptab"><div class="up"></div>Map</li> <li class="featurestab"><div class="up"></div>Features</li> <li class="voucherstab"><div class="up"></div>Offers</li> </ul>

And the here's the javascript:

$(window).load(function(){ $('.tab:not(.aboutus)').hide(); $('.tabs li').click(function(){ var thisAd = $(this).parent().parent(); $(thisAd).children('.tab').hide(); $(thisAd).children('.'+$(this).attr('class').replace('tab','')).show(); $('.tabs li').removeClass('active'); $(this).addClass('active'); }); if(window.location.hash) { if (window.location.hash == "#map") { $(".Advert").children('.tab').hide(); $(".Advert").children('.map').show(); $('.tabs li').removeClass('active'); $('.maptab').addClass('active'); } if (window.location.hash == "#voucher") { $(".Advert").children('.tab').hide(); $(".Advert").children('.vouchers').show(); } } });

I have the bootstrap.js plugin from here and would like to use that, if anyone was familiar with that it'd be ideal.

Here's how I would like it to work.

Update: This is what I have now, but the fade effect is different for each tab almost - I like the transition back to the About Us tab which isn't as "heavy" as the transition of the others. The offers tab is leaving remnants of the 'Features' tab content too.

 $(window).load(function(){ $('.tab:not(.aboutus)').fadeOut(); $('.tabs li').click(function(){ var thisAd = $(this).parent().parent(); $(thisAd).children('.tab').fadeOut(); $(thisAd).children('.'+$(this).attr('class').replace('tab','')).fadeIn(); $('.tabs li').removeClass('active'); $(this).addClass('active'); }); newContent.hide(); currentContent.fadeOut(750, function() { newContent.fadeIn(500); currentContent.removeClass('current-content'); newContent.addClass('current-content'); }); if(window.location.hash) { if (window.location.hash == "#map") { $(".Advert").children('.tab').fadeOut(750); $(".Advert").children('.map').fadeIn(500); $('.tabs li').removeClass('active'); $('.maptab').addClass('active'); } if (window.location.hash == "#voucher") { $(".Advert").children('.tab').fadeOut(750); $(".Advert").children('.vouchers').fadeIn(500); } } });

31193716 0 UITabBarController - transition from one tab's navigation stack to a view controller of another tab's navigation stack

Novice iOS developer here. I am making a simple tabbed chat application in Swift using a UITabBarController. For simplicity, let's assume the application only has two tabs, "Contacts" and "Chats". Each of the two tabs has a navigation controller.

The "Chats" navigation stack begins with a UITableViewController called "ChatsTableViewController" which lists the user's chats. When the user selects a chat, the app segues to a MessagesViewController which displays the messages for the selected chat.

The "Contacts" navigation stack includes a UITableViewController which lists the user's contacts. Upon selecting a contact, another view controller is presented modally, asking the user whether they would like to begin a chat with the selected contact, and giving them the option to cancel. If the user chooses to begin a chat, I would like to transition from this modal view controller to the MessagesViewController of the "Chats" tab, passing the information necessary to display the chat (which I have at the ready in the modal view controller).

When the MessagesViewController loads, regardless of whether we get to it by selecting a chat from the "Chats" tab or by creating a new chat from the "Contacts" tab, it should have a navigation bar at the top with a "Back" button that takes the user to the ChatsTableViewController.

I have done a good deal of searching, but have not found any solutions that fit what I need. Any suggestions would be greatly appreciated! Here is a summary of what I am looking for.

Standard way to perform a transition from a view controller in one tab's navigation stack to a view controller (that is not the root view controller in my case) of another tab's navigation stack, while passing relevant information to display in the destination view controller.
The view controller I transition to should have a navigation bar with a back button that takes the user to the previous view controller in its navigation stack, just as if they had accessed it from the normal navigation flow of the tab.

EDIT: I've found that you can easily switch tabs programmatically using self.tabBarController?.selectedIndex = index_of_tab_to_switch_to, however, this takes me to the first view of the tab and I am still unsure of how I can pass data. Any thoughts on how I can proceed?

Maybe it won't be a full answer to your question, but here's what I've been able to find so far : there is some kind of a partial answer in the book "Extending and Embedding PHP", written by Sara Golemon (amazon ; some parts are also available on google books).

The relevant part (a note at the top of page 56) is :

Ever wonder why some extensions are configured using --enable-extname and some are configured using --with-extename? Functionnaly, there is no difference between the two. In practice, however, --enable is meant for features that can be turned on witout requiring any third-party libraries. --with, by contrast, is meant for features that do have such prerequisites.

So, not a single word about performance (I guess, if there is a difference, it is only a matter of "loading one more file" vs "loading one bigger file") ; but there is a technical reason behind this possibility.

I guess this is done so PHP itself doesn't require an additionnal external library because of some extension ; using the right option allows for users to enable or disable the extension themselves, depending on whether or not they already have that external library.

This has nothing to do with calling revalidate as recommended by another and likely has all to do with calling a method on the wrong object. In your showEmployeesActionPerformed method you create a new Company object, one that is not visualized. The key is to call this method on the proper reference, on the visualized GUI. You do this by passing a reference to the visualized GUI object into the class that is wanting to call methods on it. This can be done via a setCompany method:

setCompany(Company company) { this.company = company); }

or via a constructor parameter.

It appears that you are using this database migration solely for populating the data.

Database migrations are meant for changing the database schema, not for populating the database (though you can add some logic to populate the database after the change; for example, if you add a column - role to users table, you can add some custom logic to populate the newly added field for existing entries in users table). Refer to rails api - migrations for details.

If you forgot add the code to populate the database in your previous database migration, you can undo the previous migration and apply it again using:

rake db:rollback ... Edit the previous migration ..Add the code to populate rake db:migrate

If you just want to populate the database, you should seed the database instead. Watch this railscast for more information.

EDIT: To seed the database:

Create a file called db/seeds.rb
Add the record creation code like this:

['Sampath', 'Suresh'].each do |name| User.create(role: 'admin', username: name) end

Then,

rake db:seed

This will read the seeds.rb and populate the database.

Solution:

What you are looking for is called Structural Search/Replace.

It is not very well documented but it is Extremely Powerful once you grok it completely.

There are a few examples in the Existing Templates that you can probably modify and learn from, the following will do what you are asking for now.

Here is how:

Go to the Menu: Edit -> Find -> Replace Structurally and use the following Search Template.

System.out.println($EXPRESSION$);

Check Case Sensitive and make File Type = Java Source

Set the Scope of the search to Project Files for everything.

If you want to just remove it all you can just make sure the Replace Template field is blank.

You could comment them all out with a Replace Template of //System.out.println($EXPRESSION$); or /* System.out.println($EXPRESSION$); */

Better Solution:

Use the Structural Search/Replace to add private static final Logger L = LoggingFactory($Class$.class); to all the classes with the System.out.println() statements.

Then replace all the System.out.println($EXPRESSION$); with L.info($EXPRESSION$);

You can even do things sophisticated things like the following:

This is just an example idea, the body of the catch needs to only have the the System.out.println($EXPRESSION$) a more sophisticated block to grab other expressions and keep them would be an exercise for the reader.

try { $TryStatement$; } catch($ExceptionType$ $ExceptionRef$) { System.out.println($EXPRESSION$); }

with

try { $TryStatement$; } catch($ExceptionType$ $ExceptionRef$) { L.error($EXPRESSION$); }

Best Solution:

Always use a Logger instead of System.out.println() in everything. Even in scratch classes used for experimenting, they eventually end up in production code at some point!

In the original view controller add a IBAction that you want to handle the call back.

In IB Control Drag from the cell to the Exit icon at the top of the view. On release you will see a a pop up menu with the name of available IBAction methods. Choose your IBAction method.

I don't remember wether if you add a sender variable to the IBAction, you can retrieve info from it.

Firefox is having issues on thier current release of the browser and I am sure they are all aware of it, but really, if it does not get fixed soon, they will loose even more market share. which would be a shame really.

cherlietfl is right.

The problem is that you break the reference to the messages array since you assign a new array to messages inside your get function. But concat is doing this as well.

Try this:

Restangular.all('/api/messages/').getList({'_id': userId}).then(function(docs){ messages.splice(0, messages.length); // clear the array messages.push.apply(messages, docs); //add the new content });

19451800 0 SVN resolve tree conflict in merge

I have an SVN merge tree conflict that i can't figure out how to resolve and i'm hoping you guys(girls) can help out.

Here's the situation: i created a branch A from trunk to do some development. Then i created a branch B, from branch A. Both branches are evolving concurrently.

At some point i cherry-picked some revisions from branch B into trunk to get some features developed in branch B.

Now, i synced branch A with trunk:

~/branch_a$ svn merge ^/trunk ~/branch_a$ svn commit

No problems here. Next step is to sync B with A:

~/branch_b$ svn merge ^/trunk

Here i get some tree conflicts, in files/dirs that already existed in trunk before the merge but were changed in the cherry-picks i did earlier (don't know if it has anything to do with it, i'm just mentioning it):

 C some_dir/other_dir/some_file.php > local add, incoming add upon merge C some_other_dir/some_sub_dir > local add, incoming add upon merge

Essentially i want the versions of the files that are coming in from the merge and discard the current version. What's the best way to solve this?

Thanks in advance!

2079615 0 Seeking good practice advice: multisite in Drupal

I'm using multisite to host my client sites.

During development stage, I use subdomain to host the staging site, e.g. client1.mydomain.com.
And here's how it look under the SITES folder:

/sites/client1.mydomain.com

When the site is completed and ready to go live, I created another folder for the actual domain, e.g. client1.com. Hence:

/sites/client1.com

Next, I created symlinks under client1.com for FILES and SETTINGS.PHP that points to the subdomain
i.e.

/sites/client1.com/settings.php --> /sites/client1.mydomain.com/settings.php /sites/client1.com/files --> /sites/client1.mydomain.com/files

Finally, to prevent Google from indexing both the subdomain and actual domain, I created the rule in .htaccess to rewrite client1.mydomain.com to client1.com, therefore, should anyone try to access the subdomain, he will be redirected to the actual domain.

This above arrangement works perfectly fine. But I somehow feel there is a better way to achieve the above in much simplified manner. Please feel free to share your views and all advice is much appreciated.

This does not explain why your method stops so soon, but you need to take care of it or you will have an even stranger problem with the result data being completely garbled.

From the APi doc of DataInputStream.read():

Reads some number of bytes from the contained input stream and stores them into the buffer array b. The number of bytes actually read is returned as an integer.

You need to use that return value and call the write() method that takes and offset and length.

It's just personal preference really, and has to do with the layout of your python modules.

Let's say you have a module called erikutils. There are two ways that it can be a module, either you have a file called erikutils.py on your sys.path or you have a directory called erikutils on your sys.path with an empty __init__.py file inside it. Then let's say you have a bunch of modules called fileutils, procutils, parseutils and you want those to be sub-modules under erikutils. So you make some .py files called fileutils.py, procutils.py, and parseutils.py:

erikutils __init__.py fileutils.py procutils.py parseutils.py

Maybe you have a few functions that just don't belong in the fileutils, procutils, or parseutils modules. And let's say you don't feel like creating a new module called miscutils. AND, you'd like to be able to call the function like so:

erikutils.foo() erikutils.bar()

rather than doing

erikutils.miscutils.foo() erikutils.miscutils.bar()

So because the erikutils module is a directory, not a file, we have to define it's functions inside the __init__.py file.

In django, the best example I can think of is django.db.models.fields. ALL the django *Field classes are defined in the __init__.py file in the django/db/models/fields directory. I guess they did this because they didn't want to cram everything into a hypothetical django/db/models/fields.py model, so they split it out into a few submodules (related.py, files.py, for example) and they stuck the made *Field definitions in the fields module itself (hence, __init__.py).

While it is not free (but $39), FireDaemon has worked so well for me I have to recommend it. It will run your batch file but has loads of additional and very useful functionality such as scheduling, service up monitoring, GUI or XML based install of services, dependencies, environmental variables and log management.

I started out using FireDaemon to launch JBoss application servers (run.bat) but shortly after realized that the richness of the FireDaemon configuration abilities allowed me to ditch the batch file and recreate the intent of its commands in the FireDaemon service definition.

There's also a SUPER FireDaemon called Trinity which you might want to look at if you have a large number of Windows servers on which to manage this service (or technically, any service).

14874445 0 Is the Monolithic God object in Javascript a performance concern?

The way it is:

I have recently joined a webapp project which maintains, as a matter of standard, one single globally-available (ie, itself a property of window) object which contains, as properties or recursive sub-properties, all the functions and variables necessary to run the application — including stateful indicators for all the widgets, initialization aliases, generic DOM manipulation methods — everything. I would try to illustrate with simplified pseudo-code, but that defeats the point of my concern, which is that this thing is cyclopean. Basically nothing is encapsulated: everything single granular component can be read or modified from anywhere.

The way I'd like it:

In my recent work I've been the senior or only Javascript developer so I've been able to write in a style that uses functions, often immediately invoked / self-executing, for scoping discreet code blocks and keeping granular primitives as variables within those scopes. Using this pattern, everything is locked to its execution scope by default, and occasionally a few judiciously chosen getter/setter functions will be returned in cases where an API needs to be exposed.

…Is B more performant than A on a generic level?

Refactoring the code to functional parity from style A to style B is a gargantuan task, so I can't make any meaningful practical test for my assertion, but is the Monolithic God object anti-pattern a known performance monster compared to the scoped functional style? I would argue for B for the sake of legibility, code safety, and separation of concerns... But I imagine keeping everything in memory all the time, crawling though lookup chains etc would make it either an inherently performance-intensive exercise to access anything, or at least make garbage collection a very difficult task.

Check to see how fragmented your indexes are. At my company we have a nightly import process that trashes our indexes and over time it can have a profound impact on data access speeds. For example we had a SQL procedure that took 2 hours to run one day after de-fragmenting the indexes it took 3 minutes. we use SQL Server 2005 ill look for a script that can check this on MySQL.

import asyncio import inspect class escape(object): def __init__(self, value): self.value = value class _asynciter(object): def __init__(self, iterator): self.itr = iterator async def __aiter__(self): return self async def __anext__(self): try: yielded = next(self.itr) while inspect.isawaitable(yielded): try: result = await yielded except Exception as e: yielded = self.itr.throw(e) else: yielded = self.itr.send(result) else: if isinstance(yielded, escape): return yielded.value else: return yielded except StopIteration: raise StopAsyncIteration def asynciter(f): return lambda *arg, **kwarg: _asynciter(f(*arg, **kwarg))

Then your code could be written as:

@asynciter def countdown(n): while n > 0: yield from asyncio.sleep(1) #or: #yield asyncio.sleep(1) n = n - 1 yield n async def do_work(): async for n in countdown(5): print(n) asyncio.get_event_loop().run_until_complete(do_work())

To learn about the new syntax, and how this code works, see PEP 492

39621578 1 Match multiple times a group in a string

i'am trying to use regular expression. I have this string that has to be matched

4377999 0 Mapping vs composition

If I have two classes with a one-to-one relationship, when's a good time to use mapping.

class A { ... } class B { ... } class C { Map<A,B> a2b; }

And when's a good time to use composition?

class A { B myB; } class B { ... }

Would the answer change if the relationship was one-to-many and many-to-many?

35289597 0 Excel 2010 Cell Validation - Grouped List

Is it possible (without the use of user forms, or form controls) to have a grouped validation list in-cell, where the group title cannot be selected. So for example:

Fruit
Apple
Banana
Veg
Potato
Carrot

I feel like I've been searching for an absolute age now, and I'm getting no where fast. The reason I cannot use form controls as that there are 8 sheets, each with a few thousand rows (possible) and each entry must have this selection. I have done this before with dependant lists across multiple columns but I'd like to trim everything down.

Any ideas? I don't want a clear cut solution if one exists, just a nudge in the right direction. Any help appreciated.

21290403 0 WebSockets and HTTPS load balancers

I cannot find authoritative information about how WSS interacts with HTTPS proxies and load balancers.

I have a load balancer that handles the SSL (SSL off-loading), and two web servers that contains my web applications and handle the requests in plain HTTP. Therefore, the customers issue HTTPS requests, but my web servers get HTTP requests, since the load balancer takes care of the SSL certificates handling.

I am developing now an application that will expose WebSockets and SSL is required. But I have no clear idea about what will happen when the load balancer gets a secure HTTPS handshake for WSS.

Will it just relay the request as normal handshake to the web server? WebSockets use a "Upgrade:WebSocket" HTTP header that is only valid for the first hop (as there is also "Connection:Upgrade", will this be a problem?

Cheers.

I've come across this myself before. Adobe's documentation on Traversing XML structures isn't exactly clear on the point.

Their documentation states that if there is more than one element with a particular name you have to use array index notation to access it:

var testXML:XML = <base> <book>foo</book> <book>bar</book> </base> var firstBook:XML = testXML.book[0];

Then it goes on to say that if there is only one element with a particular name then you can omit the array index notation:

var testXML:XML = <base> <book>foo</book> </base> var firstBook:XML = testXML.book;

This means that when you try and force coercion to an Array type it doesn't work since it sees the single element as an XMLNode and not an XMLList.

If you are lucky you can just check the number of children on your <my_claims> node and decide if you want to warp the single element in an ArrayCollection or if you can use the automatic coercion to work for multiple elements.

Quoting from RegEx match open tags except XHTML self-contained tags :

You can't parse [X]HTML with regex. Because HTML can't be parsed by regex. Regex is not a tool that can be used to correctly parse HTML. [...] Regular expressions are a tool that is insufficiently sophisticated to understand the constructs employed by HTML. HTML is not a regular language and hence cannot be parsed by regular expressions. Regex queries are not equipped to break down HTML into its meaningful parts.

The conclusion I case was the same as the author:

Have you tried using an[sic] XML parser instead?

Which is what you can do!

Try this:

var fragment = document.createDocumentFragment(); var elem = document.createElement('div'); fragment.appendChild(elem); elem.innerHTML = '<svg viewBox="0 0 120 120" version="1.1" xmlns="http://www.w3.org/2000/svg"><circle cx="60" cy="60" r="50"/></svg>'; alert(elem.getElementsByTagName('circle')[0].getAttribute('cx'));

It should alert 60.

Javascript provides all the tools to mess with this. Just pretend that the string is HTML and you should be fine!

Note: that code is just an example! Addapting it to work properly is easily done in 5 minutes or less.

31804966 0 Running NodeJs http-server forever with PM2

My question is about running HTTP-server in combination with PM2.

The problem i face is that:

HTTP-server requires as input a folder which is the root of the website and a port number to run the website on.
PM2 doesn't recognize the HTTP-server command, even when HTTP-server is installed with the -g option.

So i tried the following (note the double dash which should pass the parameters to the HTTP-server script:

/node_modules/http-server/lib$ pm2 start http-server.js -- /home/unixuser/websiteroot -p8686

But it doesn't work.

I also tried:

http-server /home/unixuser/websiteroot -p8686

Which does work, but doesn't have the great support of pm2 ?

Any suggestions would be great, thanks!

41023266 0 Is there an OData dependency graph somewhere?

I'm following this guide to migrate an app I developed to an open framework. I get to the part where I'm supposed to install all the OData references. Specifically these:

Install-Package Angularjs Install-Package Microsoft.OData.Client Install-Package Microsoft.OData.Core Install-Package Microsoft.OData.Edm Install-Package Microsoft.Spatial Install-Package Microsoft.AspNet.OData Install-Package Microsoft.AspNet.WebApi.WebHost

And these are the errors I get:

Unable to resolve dependencies. 'Microsoft.OData.Core 7.0.0' is not compatible with 'Microsoft.OData.Client 6.15.0 constraint: Microsoft.OData.Core (= 6.15.0)'. Unable to find a version of 'Microsoft.OData.Core' that is compatible with 'Microsoft.OData.Client 6.15.0 constraint: Microsoft.OData.Core (= 6.15.0)'.

I started running my app over and over until it throws an exception and then adding a bingindRedirect to my Web.config to target the currently installed versions. But this doesn't seem right and will add a lot of maintenance later on. I know how to install old versions and nightly versions. But I have no idea which versions to install. Is there some place that tells me which versions work together correctly?

According to NuGet, I have version 6.15.0 of each installed. So why am I getting errors?

26174400 0 RegEx - Extract Domain Name from multiple sub-domains

This will do the trick:

if($_SERVER['REMOTE_ADDR'] === '127.0.0.1') { // do something }

Be careful you don't rely on X_FORWARDED_FOR as this header can be easily (and accidentally) spoofed.

The correct way to do this would be to set an environmental variable in your server configuration and then check that. This will also allow you to toggle states between a local environment, staging and production.

38536136 0 Unique methods for use through the class rather than an object

So, I'm beginning to learn Java and I think it's an awesome programming language, however I've come across the static keyword which, to my understanding, makes sure a given method or member variable is accessible through the class (e.g. MyClass.main()) rather than solely through the object (MyObject.main()). My question is, is it possible to make certain methods only accessible through the class and not through the object, so that MyClass.main() would work, however MyObject.main() would not? Whilst I'm not trying to achieve anything with this, I'd just like to know out of curiosity.

In my research I couldn't find this question being asked anywhere else, but if it is elsewhere I'd love to be pointed to it!

Forgive me if it's simple, however I've been thinking on this for a while and getting nowhere.

Thanks!

There are two (or more) problems. The first: you are using typedef when you are trying to declare an array of structs. Don't. Instead of

typedef struct Symbles symbles_arr[MAX_SYMBOLS_ENTRIES_EXTERNALS];

use

struct Symbles symbles_arr[MAX_SYMBOLS_ENTRIES_EXTERNALS];

Notice that you now have the structure (not a pointer to the structure) - so when you want to access an element you need . not -> Thus:

 symbles_arr[symbol_counter]->symbolName=*toCheck;

needs to become

 strcpy(symbles_arr[symbol_counter].symbolName, *toCheck);

because you allocated space for the symbol name in the structure, and you can't just take that pointer and point it somewhere else.

Finally - you don't need to malloc space for toCheck since strtok actually returns a pointer to the original string (it doesn't make a copy). The side effect of this is that your input string (the one passed to strtok) becomes mangled in the process - after you're done using it, it has a lot of '\0' added.

There may be other problems, but this should get you on your way...

One way to go about it is to create a view with your basic logic:

CREATE VIEW myview AS SELECT * FROM mytable WHERE column_b = 'X' AND column_c = 'Y'

Now, this logic can be reused:

SELECT * FROM myview WHERE column_a NOT IN (SELECT column_k FROM myview)

By using add, you are effectively getting a calendar instance that is 2015 years, 6 months, 20 days, and 19 hours later than now. Instead use the constructor:

Calendar cal = new GregorianCalendar(2015, 5, 20, 19, 0);

and do not call add.

Alternatively, you can use set instead of add:

cal.set(Calendar.YEAR, 2015); cal.set(Calendar.MONTH, 5); // 0-based cal.set(Calendar.DAY_OF_MONTH, 20); cal.set(Calendar.HOUR, 19); cal.set(Calendar.MINUTE, 0);

28912282 0 Trying to write "<<<" in ksh

I am having trouble with the code below:

IFS=: read c1 c2 c3 c4 rest <<< "$line"

Don't get me wrong this code works good but it doesn't seem to be used for ksh. I basically need to write the same code without the "<<<". There is not much info on the "<<<" online. If anybody has any ideas it would be much appreciated.

EDIT:

Ok code is as follows for the entire portion of programming:

m|M) #Create Modify Message clear echo " Modify Record " echo -en '\n' echo -en '\n' while true do echo "What is the last name of the person you would like to modify:" read last_name if line=$(grep -i "^${last_name}:" "$2") then oldIFS=$IFS IFS=: set -- $line IFS=$oldIFS c1=$1 c2=$2 c3=$3 c4=$4 shift; shift; shift; shift rest="$*" echo -e "Last Name: $1\nFirst Name: $2\nState: $4" while true do echo "What would you like to change the state to?:" read state if echo $state | egrep -q '^[A-Z]{2}$' then echo "State: $state" echo "This is a valid input" break else echo "Not a valid input:" fi done echo -e "Last Name: $c1\nFirst Name: $c2\nState: $state" echo "State value changed" break else echo "ERROR: $last_name is not in database" echo "Would you like to search again (y/n):" read modify_choice case $modify_choice in [Nn]) break;; esac fi done ;;

Ok so everything works except for the

echo -e "Last Name: $c1\nFirst Name: $c2\nState: $state"

It will just show:

Last Name:

First Name:

State:

So I can see it is not adding it to my echo correctly.

FINAL EDIT

CODE:

#Case statement for modifying an entry m|M) #Create Modify Message clear echo " Modify Record " echo -en '\n' echo -en '\n' while true do echo "What is the last name of the person you would like to modify:" read last_name if line=$(grep -i "^${last_name}:" "$2") then echo "$line" | while IFS=: read c1 c2 c3 c4 rest; do echo -e "Last Name: $c1\nFirst Name: $c2\nState: $c4" last=$c1 first=$c2 done while true do echo "What would you like to change the state to?:" read state if echo $state | egrep -q '^[A-Z]{2}$' then echo "State: $state" echo "This is a valid input" break else echo "Not a valid input:" fi done echo -e "Last Name: $last\nFirst Name: $first\nState: $state" echo "State value changed" break else echo "ERROR: $last_name is not in database" echo "Would you like to search again (y/n):" read modify_choice case $modify_choice in [Nn]) break;; esac fi done ;;

An IMHO improved way based upon ZZ Coder's solution is to use a ResponseInterceptor to simply track the last redirect location. That way you don't lose information e.g. after an hashtag. Without the response interceptor you lose the hashtag. Example: http://j.mp/OxbI23

private static HttpClient createHttpClient() throws NoSuchAlgorithmException, KeyManagementException { SSLContext sslContext = SSLContext.getInstance("SSL"); TrustManager[] trustAllCerts = new TrustManager[] { new TrustAllTrustManager() }; sslContext.init(null, trustAllCerts, new java.security.SecureRandom()); SSLSocketFactory sslSocketFactory = new SSLSocketFactory(sslContext); SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register(new Scheme("https", 443, sslSocketFactory)); schemeRegistry.register(new Scheme("http", 80, new PlainSocketFactory())); HttpParams params = new BasicHttpParams(); ClientConnectionManager cm = new org.apache.http.impl.conn.SingleClientConnManager(schemeRegistry); // some pages require a user agent AbstractHttpClient httpClient = new DefaultHttpClient(cm, params); HttpProtocolParams.setUserAgent(httpClient.getParams(), "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:13.0) Gecko/20100101 Firefox/13.0.1"); httpClient.setRedirectStrategy(new RedirectStrategy()); httpClient.addResponseInterceptor(new HttpResponseInterceptor() { @Override public void process(HttpResponse response, HttpContext context) throws HttpException, IOException { if (response.containsHeader("Location")) { Header[] locations = response.getHeaders("Location"); if (locations.length > 0) context.setAttribute(LAST_REDIRECT_URL, locations[0].getValue()); } } }); return httpClient; } private String getUrlAfterRedirects(HttpContext context) { String lastRedirectUrl = (String) context.getAttribute(LAST_REDIRECT_URL); if (lastRedirectUrl != null) return lastRedirectUrl; else { HttpUriRequest currentReq = (HttpUriRequest) context.getAttribute(ExecutionContext.HTTP_REQUEST); HttpHost currentHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST); String currentUrl = (currentReq.getURI().isAbsolute()) ? currentReq.getURI().toString() : (currentHost.toURI() + currentReq.getURI()); return currentUrl; } } public static final String LAST_REDIRECT_URL = "last_redirect_url";

use it just like ZZ Coder's solution:

HttpResponse response = httpClient.execute(httpGet, context); String url = getUrlAfterRedirects(context);

Force, I must tell you that an Android Service do not require root access instead some actions(i.e. Access, Read, Write system resources) requires Root Permissions. Every Android Service provided in Android SDK can be run without ROOT ACCESS.

You can make the actions to execute with root permissions with the help of shell commands.

I have created an abstract class to help you with that

import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.IOException; import java.util.ArrayList; import android.util.Log; public abstract class RootAccess { private static final String TAG = "RootAccess"; protected abstract ArrayList<String> runCommandsWithRootAccess(); //Check for Root Access public static boolean hasRootAccess() { boolean rootBoolean = false; Process suProcess; try { suProcess = Runtime.getRuntime().exec("su"); DataOutputStream os = new DataOutputStream(suProcess.getOutputStream()); DataInputStream is = new DataInputStream(suProcess.getInputStream()); if (os != null && is != null) { // Getting current user's UID to check for Root Access os.writeBytes("id\n"); os.flush(); String outputSTR = is.readLine(); boolean exitSu = false; if (outputSTR == null) { rootBoolean = false; exitSu = false; Log.d(TAG, "Can't get Root Access or Root Access deneid by user"); } else if (outputSTR.contains("uid=0")) { //If is contains uid=0, It means Root Access is granted rootBoolean = true; exitSu = true; Log.d(TAG, "Root Access Granted"); } else { rootBoolean = false; exitSu = true; Log.d(TAG, "Root Access Rejected: " + is.readLine()); } if (exitSu) { os.writeBytes("exit\n"); os.flush(); } } } catch (Exception e) { rootBoolean = false; Log.d(TAG, "Root access rejected [" + e.getClass().getName() + "] : " + e.getMessage()); } return rootBoolean; } //Execute commands with ROOT Permission public final boolean execute() { boolean rootBoolean = false; try { ArrayList<String> commands = runCommandsWithRootAccess(); if ( commands != null && commands.size() > 0) { Process suProcess = Runtime.getRuntime().exec("su"); DataOutputStream os = new DataOutputStream(suProcess.getOutputStream()); // Execute commands with ROOT Permission for (String currentCommand : commands) { os.writeBytes(currentCommand + "\n"); os.flush(); } os.writeBytes("exit\n"); os.flush(); try { int suProcessRetval = suProcess.waitFor(); if ( suProcessRetval != 255) { // Root Access granted rootBoolean = true; } else { // Root Access denied rootBoolean = false; } } catch (Exception ex) { Log.e(TAG, "Error executing Root Action", ex); } } } catch (IOException ex) { Log.w(TAG, "Can't get Root Access", ex); } catch (SecurityException ex) { Log.w(TAG, "Can't get Root Access", ex); } catch (Exception ex) { Log.w(TAG, "Error executing operation", ex); } return rootBoolean; } }

Extend your class with RootAccess or create an instance of RootAccess class and Override runCommandsWithRootAccess() method.

do all JVMs optimize the usage of Strings in a way such that when the same string is used several times, it will always be the same physical instance?

I doubt that very much. In the same class file, when definined like:

String s1 = "Yes"; String s2 = "Yes";

you'll probably have s1 == s1.

But if you have like:

String x = loadTextFromFile(); // file contains es StringBuilder b = new StringBuilder(); s2 = b.append("Y").append(x).toString(); // s2 = "Yes"

I don't think the runtime is going to check and compare all the loaded strings to the return value of them builder.

So, always compare objects with equals(). That's good advice anyway since every good equals starts with:

if (this == o) { return true; }

30480178 0 innerText auto truncating long text inside a DOM element

I am trying to access the content inside a td element through the JavaScript innerText property (inside an excel VBA macro). It works perfectly for all cases except for this one case where the text inside the td element is very long (greater than 85982 characters).

Upon inspection of the text extracted by innerText, I found that innerText seems to be truncating the text after a certain length. Note that this doesn't happen for other cases where the text size is small.

Also, it seems that Mozilla's textContent property has a similar problem as well. I tried accessing the truncated part of the text using the developer console in Firefox for the aforementioned DOM element, but it seems that text isn't there in the extracted content (but the not truncated text is there - just like with innerText).

Does anyone know how to bypass this restriction? Is there some internal limit on these functions?

Here's my VBA code that has this problem:

MyInnerText = objElement.ChildNodes(3).innerText

Here's an equivalent code run in the Firefox console which has the same problem:

var t = document.getElementsByName("chapter11")[0].parentNode.children[3].textContent; t.match("some text that is in the part being truncated.");

For Firefox, this problem seems to go away if I inspect the element, and click "Show all 3396" nodes. After those nodes are visible, the textContent does not truncate the text anymore.

Please do note that I want to be able to extract the text from inside a VBA script using the Internet Explorer object.

You say it works if you use the full path to tclsh84.exe. So, a solution might be to find out that full path and use it in your call to proc_open.

If you know your tclsh84.exe is in the directory in which your PHP script is, you could use something based on dirname and __FILE__ ; a bit like this, I suppose :

$dir = dirname(__FILE__); var_dump($dir); // directory in which the current PHP script is in $path = $dir . DIRECTORY_SEPARATOR . 'tclsh84.exe'; var_dump($path);

Considering the PHP script I am using is /home/squale/developpement/tests/temp/temp.php, I would get :

string '/home/squale/developpement/tests/temp' (length=37) string '/home/squale/developpement/tests/temp/tclsh84.exe' (length=49)

And, if needed, you can use '..' to go up in the directories tree, and, then use directories names to go down.

Another solution might be to make sure that the program you are trying to execute is in your PATH environment variables -- but if it's a program that's used only by your application, it doesn't make much sense to modify your PATH, I guess...

6204109 0 Regex get content between two pipes AND return a space where two pipes are next to each other with no spaces

How can I get all content between pipes and return a space where it comes across two pipes next to each other?

An example string and desired output is:

|test1| test2|test3 || test 4 | Result1: "test1" Result2: "test2" Result3: "test3" Result4: " " Result5: "test4"

The closest I've got so far is:

/[^\|]+)/ which will get all data between pipes but does not detect ||.
/\|([^\|]*)/ which will get all data between pipes and detect || but have an extra whitespace result at the end.

24409698 1 Django view function not being called

Ths is the function in question. The problem is that it does not seem to do be called. User can download any files on the server, regardless of whether pk matches request.user.id or not.

def permit(request, pk): # First I sanitize system_path from request, then... if int(request.user.id) == int(pk) and int(request.user.id) >= 1: sendfile(request, system_path) else: return render_to_response('forbidden.html') return HttpResponseRedirect('/notendur/list')

As you can see, it takes pk and compares it to request.user.id, and serves the file if that is the case.

Then the relevant bits of urls.py

urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), #upload urls (r'^notendur/', include('notendur.urls')), #This needs to be changed to welcome.html (r'^$', RedirectView.as_view(url='/notendur/list/')), # Just for ease of use. #security url(r'^media/uploads/(?P<pk>[^/]+)', 'notendur.views.permit'), url(r'^media', 'notendur.views.permit'), )

This error sort of came out of the blue. I hadn't edited anything pertaining to this as far as I am aware.

I know the function is not being called because I commented out the sendfile() and put render_to_response('forbidden.html') instead. Did not have any effect; user could still download file unexamined.

If you'd use only id's the selection would be faster, but you would also have to do more selections than if you would use classes. Provided that the css is clean. Problem with basing style on id's in general is that you forgo all reuse of that style.

The best way to go is to link style to classes. That gives you adequate speed and keeps the css file smaller. Smaller files are much more important for performance in most sites than faster execution on the client. Typical clients will render a complex page in microseconds, once they have all the resources that is.

The css you point out is using a sprite, which could very well be generated with compass or something similar. It's important to see the original code too before making harsh judgements about the quality.

In order to Updateupdate the data on the database your SqlDataAdapter need to have its InsertCommand, UpdateCommand, DeleteCommand properties set.

So, try the below code:

 ds.Tables[0].Rows.Add(newRow); SqlCommandBuilder commandBuilder = new SqlCommandBuilder(adp); adp.DeleteCommand = commandBuilder.GetDeleteCommand(true); adp.UpdateCommand = commandBuilder.GetUpdateCommand(true); adp.InsertCommand = commandBuilder.GetInsertCommand(true); adp.Update(ds.Tables[0]); //connection.UpdateDatabase(ds); connection.Close();

Edit: The Update method takes the name of a DataSet and a table. The DataSet for us is ds, which is the one we passed in to our UpdateDatabase method when we set it up. After a dot, you type the name of a table in your dataset.

I wrote a server side script that shows the output of headers from both examples and APIKEY was set identically in both cases. There were some differences in HTTP_ACCEPT / HTTP_ACCEPT_ENCODING and WWW::Mechanize adds some additional headers:

'downgrade-1.0' => '1' 'force-response-1.0' => '1' 'nokeepalive' => '1'

localStorage()
cookie
cookie-like hacks
server-side

If this intro could be annoying for repeat users and the site has a login, I'd persist it server side. You don't want the user being hit with it when they use a different browser or computer to access your site.

If not, use localStorage().

If you want to keep record of all queries that are executed, you can enable either the General Query Log or the Slow Query Log and set the threshold to 0 seconds (any query that takes more than 0 seconds will be logged).

Another option is the Binary log. However, binary log does not keep record of queries like SELECT or SHOW that do not modify data.

Note that these logs get pretty big pretty fast in a server with traffic. And that both might contain passwords so they have to be protected from unauthorized eyes.

Because the triple design doesn't prevent you from using a closure, while the alternative approach prevents you from not using closures. Sometimes the external-state design is the simpler approach.

For instance, say that you're using a for loop to iterate which pages to display in the response to a RESTful query. With external-state-based loops, you can write a function that iterates pages based on a table representing the state-representational parameters of the query (which you construct from the URL once and reuse for several other functions). With triples, you can iterate with just those values without being forced to wrap it (and every other function like it) in a closure constructor.

21938921 0 How to manipulate the output to a ItemsSource?

With this Previous Question i was able too manage to show the output. I've reading alot of posts here on stackoverflow, but cant find the right solution for the next:

How to manipulate the output too ItemsSource, because:

{"order_id":"12345678","itemList":["235724","203224","222224","222324","230021"],"amount":["65","50","10","25","42"]}

The number 235724 is also used within a IMG url and need to become like "235724 X 65" for a selectable listbox.

Solution was:

ObservableCollection<CreateItem> pitems = new ObservableCollection<CreateItem>(); for (int i = 0; i < rootObject.itemList.Count; i++) { var itemsku = rootObject.itemList[i]; var amount = rootObject.amount[i]; pitems.Add(new CreateItem() { pTitle = itemsku + " X " + amount , pImage = new BitmapImage(new Uri(string.Format("http://image.mgam79.nl/indb/{0}.jpg", itemsku)))}); } MyListBox.ItemsSource = pitems; public class CreateItem { public string pTitle { get; set; } public ImageSource pImage { get; set; } }

change

strcat(ipstr,&ipch);

strncat(ipstr, &ipch, 1);

this will force appending only one byte from ipch. strcat() will continue appending some bytes, since there's no null termination character after the char you are appending. as others said, strcat might find somewhere in memory \0 and then terminate, but if not, it can result in segfault.

from manpage:

char *strncat(char *dest, const char *src, size_t n);

The strncat() function is similar to strcat(), except that

it will use at most n characters from src; and
src does not need to be null-terminated if it contains n or more characters.

I feel your process(mosquitto) have hit the maximum number of open file descriptors limit. Check your max open files by ulimit -n. Then increase the limit to max number of connections expected by you. E.g. For 10k connection it would be ulimit -n 10000

A note on ulimit(1). It is only set for the current terminal and for persistent changes you will need to edit config files as per your Linux flavor( /etc/security/limits.conf + /etc/pam.d/common-session* on Ubuntu ).

Creating snapshots in VHD works by putting an overlay over the existing VHD image, so that any change get written into the overlay file instead of overwriting existing data. For reading the top-most data is returned: either the data from the overlay if that sector/cluster was already over-written, or from the original VHD file if it was not-yet over-written.

The vhd-util command creates such an overlay-VHD-file, which uses the existing VHD image as its so-called "backing-file". It is important to remember, that the backing-file must never be changed while snapshots still using this backing-file exist. Otherwise the data would change in all those snapshots as well (unless the data was overwritten there already.)

The process of using backing files can be repeated multiple times, which leads to a chain of VHD files. Only the top-most file should ever be written to, all other files should be handled as immutable.

Reverting back to a snapshot is as easy as deleting the current top-most overlay file and creating a new empty overlay file again, which again expose the data from the backing file containing the snapshot. This is done by using the same command again as above mentioned. This preserves your current snapshot and allows you to repeat that process multiple times. (renaming the file would be more like "revert back to and delete last snapshot".)

Warning: before re-creating the snapshot file, make sure that no other snapshots exists, which uses this (intermediate) VHD file as its backing file. Otherwise you would not only loose this snapshot, but all other snapshots depending on this one.

There might be a way to do this with less duplication, but the following should work, anyway. First, find out which columns we need to shift, and then replace those columns by the shifted versions.

to_shift = pd.isnull(df2.iloc[-1]) df2.loc[:,to_shift] = df2.loc[:,to_shift].shift(1)

Get the last row:

>>> df2.iloc[-1] one 5 two NaN three NaN Name: i, dtype: float64

See where there's missing data:

>>> pd.isnull(df2.iloc[-1]) one False two True three True Name: i, dtype: bool >>> to_shift = pd.isnull(df2.iloc[-1])

Select that portion of the frame:

>>> df2.loc[:, to_shift] two three a -0.447225 0.240786 b NaN NaN c 1.736224 0.191835 d NaN NaN e -0.310505 2.121659 f 2.542979 -0.772117 g NaN NaN h -0.350395 0.825386 i NaN NaN

Shift it:

>>> df2.loc[:, to_shift].shift(1) two three a NaN NaN b -0.447225 0.240786 c NaN NaN d 1.736224 0.191835 e NaN NaN f -0.310505 2.121659 g 2.542979 -0.772117 h NaN NaN i -0.350395 0.825386

And fill the frame with the shifted data:

>>> df2.loc[:, to_shift] = df2.loc[:, to_shift].shift(1) >>> df2 one two three a -0.691010 NaN NaN b NaN -0.447225 0.240786 c 0.570639 NaN NaN d NaN 1.736224 0.191835 e 2.509598 NaN NaN f -2.053269 -0.310505 2.121659 g NaN 2.542979 -0.772117 h 1.812492 NaN NaN i 5.000000 -0.350395 0.825386

I've been having trouble integrating bootstrap-sass into any of my Rails 4 projects. So far i'm only getting partial rendering of the bootstrap assets. I've resorted to using using the railstutorial.org in my search for bootstrap functionality. I'm using the ch5 (listing 5.4) source code yielding the following results:

The classes btn-lg, btn-primary, and navbar-right classes are working. The page yields buttons and a partially structured navbar with the links to the right. However, the navbar classes for the most part are not working. The navbar has no 'inverse' styling, the entire div is washed out with no text styling whatsoever.

I've been using 'rake assets:precompile' and restarting the server after every update to the assets pipeline.

TL;DR - In the code snippet shown above, there is no memory leak.

Do I need to use malloc instead of hardcoded size of array?

I think, you got confused by the possible underuse of char buffer[10000]; and char error_msg[10000];. These arrays are not allocated dynamically. Even the arrays are not used to their fullest capacities, there is no memory leak here.

Also, as Mr. @Vlad metioned rightly about another much possible issue in your case, actual_error_msg being a global, if the trimwhitespace() function does not have a return value which is having a global scope, (i.e., stays valid after the a() has finished execution), it may possibly lead to undefined behaviour.

To avoid that, make sure, trimwhitespace() function is either returning ^{(assuming return type is char *)}

a pointer with dynamic memory allocation (Preferred)
base address of a static array. (bad practice, but will work)

To elaborate, from the Wikipedia article about "memory leak"

In computer science, a "memory leak" is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in such a way that memory which is no longer needed is not released. ...

and

.. Typically, a memory leak occurs because dynamically allocated memory has become unreachable. ...

When memory is being allocated by your compiler, there is no scope of memory leak, as the memory (de)allocation is managed by the compiler.

OTOH, with dynamic memory allocation, allocation of memory is performed at runtime. Compiler has no information about the allocation, memory is allocated programatically, hence need to be freed programatically, also. Failing to do so leads to the "memory leak".

34695860 0 BFS for pacman ghost

I've been several days with this problem. I've searched in this forum, and in google for a solution without any luck. My problem is I am not able to make a working BFS algorithm for managing the behaviour of a pacman ghost. I think I am ignoring something in the code. I'll paste the code here, if you can help me you'll be thanked :) pacman is number 2, and ghost is number 3.

Queue<Tile> path = new LinkedList<>(); Tile start = new Tile(canvas.g1.x, canvas.g1.y, 3); Tile end = new Tile(canvas.pacman.x, canvas.pacman.y, 2); start.distance = 1; path.add(start); while (!path.isEmpty()) { Tile current = path.remove(); System.out.println(path.size()); canvas.walls[current.y][current.x] = 0; if (canvas.walls[current.y][current.x] == canvas.walls[end.y][end.x]) { end = current; System.out.println("pacman found"); break; } ArrayList<Tile> list = adyacent(current); for (Tile c : list) { if (c.distance == 0) { c.distance = current.distance + 1; path.add(c); canvas.walls[c.y][c.x] = 20; for (Tile v : path) { System.out.println("x: " + v.x + " / y: " + v.y + " / distance: " + v.distance); } } } } int dist = end.distance; System.out.println("Recolection ended, size: " + dist);

The class Tile():

public class Tile { public int x; public int y; public int distance; public int personaje; public Tile(int x, int y, int personaje) { this.x = x; this.y = y; this.personaje = personaje; distance = 0; } }

and the method adyacent():

in this method, the numbers I check are the ones with wall(each one with a diferent drawing))

public ArrayList<Tile> adyacent(Tile c) { ArrayList<Tile> surrounding = new ArrayList<>(); int ant; ant = canvas.walls[c.y][c.x + 1]; if ((ant != 7) && (ant != 8) && (ant != 9) && (ant != 11) && (ant != 12) && (ant != 13) && (ant != 14) && (ant != 15) && (ant != 16)) { surrounding.add(new Tile(c.x + 1, c.y, 3)); } ant = canvas.walls[c.y][c.x - 1]; if ((ant != 7) && (ant != 8) && (ant != 9) && (ant != 11) && (ant != 12) && (ant != 13) && (ant != 14) && (ant != 15) && (ant != 16)) { surrounding.add(new Tile(c.x - 1, c.y, 3)); } ant = canvas.walls[c.y + 1][c.x]; if ((ant != 7) && (ant != 8) && (ant != 9) && (ant != 11) && (ant != 12) && (ant != 13) && (ant != 14) && (ant != 15) && (ant != 16)) { surrounding.add(new Tile(c.x, c.y + 1, 3)); } ant = canvas.walls[c.y - 1][c.x]; if ((ant != 7) && (ant != 8) && (ant != 9) && (ant != 11) && (ant != 12) && (ant != 13) && (ant != 14) && (ant != 15) && (ant != 16)) { surrounding.add(new Tile(c.x, c.y - 1, 3)); } return surrounding; }

What I've observed is that it never reaches the System.out in which I return the size of the path. Also, where I see the size of the Queue, it seems right, but the System.out in which I see "x" and "y" and "distance" is bigger each time, much much bigger.

I set that the checked tiles change it's color, changing the number which I've got in the array: 0 is floor, 20 is transparent green. And it remains in center, and beggins to work slower and slower.

Forget to say that it never finds pacman :( thanks!

setAttribute is broken in IE7 and lower.

Use

div.className = 'pano_img_cont'

instead.

IE's implementation of setAttribute is effectively:

HTMLElement.prototype.setAttribute = function (attribute, value) { this[attribute] = value; }

… which is fine so long as the attribute name and the DOM property name are the same. class, however, is a reserved keyword in JS so the property is called className instead. This breaks in IE.

If you set the property directly, it works everywhere.

What you are doing here is creating an anonymous method that calls each service in turn and then executes that method in a parallel task. What you need is a task array.

List<Task> taskList = new List<Task>(); Task task1= Task.Factory.StartNew(() => var List1 = client1.GetList1();); Task task2= Task.Factory.StartNew(() => var List2 = client1.GetList2();); // and so forth taskList.Add(task1); taskList.Add(task2); Task.WaitAll(taskList.ToArray());

Your function introducir_datos() is declared as follows:

void introducir_datos (struct agenda cliente[30]);

But in your nested switch statement, you have this line:

introducir_datos(cliente);

where cliente is declared as char cliente[30]. So instead of providing introducir_datos() with a struct agenda* argument, you are giving it a char* argument.

Clarification:

The function introducir_datos() expects to be given an array of 30 struct agenda items as its argument.

This means that the argument type is struct agenda*, because you are sending a pointer to the first item in the array. (This is just how arrays work in C.)

You can't call this function with a char[] array as the argument, because a char[] array consists of char variables. A char doesn't have any nombre, apellido, direccion, edad or telefono members.

So your code won't compile because the compiler can't figure out what you're trying to do.

Incidentally, although you declare the variable int x; in introducir_datos(), you don't initialize it anywhere, so you need to fix that too.

namespace RecipopStartupService { public partial class Service1 : ServiceBase { public Service1() { InitializeComponent(); } protected override void OnStart(string[] args) { ProcessBatchFile(); } public void ProcessBatchFile() { Process process = new Process(); process.StartInfo.WorkingDirectory = "C:\\Webs\\AWS\\"; process.StartInfo.FileName = "C:\\Webs\\AWS\\setup.bat"; process.StartInfo.Arguments = ""; process.StartInfo.Verb = "runas"; process.StartInfo.UseShellExecute = false; process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; process.StartInfo.CreateNoWindow = true; process.StartInfo.RedirectStandardOutput = false; process.Start(); System.IO.StreamReader myOutput = process.StandardOutput; process.WaitForExit(200000); if (process.HasExited) { string results = myOutput.ReadToEnd(); } } protected override void OnStop() { } } }

The batch file:

"C:\Program Files (x86)\Subversion\bin\SVN.exe" cleanup "C:\Webs\AWS\webs" "C:\Program Files (x86)\Subversion\bin\SVN.exe" cleanup "C:\Webs\AWS\apps" "C:\Program Files (x86)\Subversion\bin\SVN.exe" update "C:\Webs\AWS\webs" REM The following directory is for .NET 2.0 set DOTNETFX2=%SystemRoot%\Microsoft.NET\Framework\v4.0.30319 set PATH=%PATH%;%DOTNETFX2% echo Uninstalling MyService... echo --------------------------------------------------- InstallUtil /u "C:\Webs\AWS\apps\MyService.exe" echo --------------------------------------------------- echo Done.

NET START MyService

I've commented out various parts to determine what stops the service from starting. It's the InstallUtil /i section as I said previously.

If someone could advise that'd be great.

In your for loop, you created var category which is already a variable

$scope.browseCategories = function(category, moveTo) { //looping in order to create a new <ul> of children categories. var html = "<ul class='unstyled'>"; for (var I = 0; I < category.Children.length; ++I) { var category = category.Children[I]; ^^^^^^^^

Try renaming that and see.

This might do whatever you are trying to achieve. Hope that helps.

But when you're doing it in angular, the best practice is to avoid any other libraries like jQuery and try to achieve it in the angular way. Angular is so powerful.

See this SO post: How do I "think in AngularJS" if I have a jQuery background?

You may disable the URL escape behavior using escapeAmp="false" attribute. By default, this is enabled, so URL parameter & will render &. This will cause a problem on reading the parameter value with parameter name.

You may need to read the parameter, request.getParameter("amp;pageNumber_hidden")
You have stop escaping the entities by adding attribute escapeAmp and set the value false as part of the <s:url> tag (Recommended)

<s:url id="loadReportsForAPageInitial" value="/loadReportsForAPage.action" escapeAmp="false">

var socket_ids = Object.keys(io.of('/namespace').sockets); socket_ids.forEach(function(socket_id) { var socket = io.of('/namespace').sockets[socket_id]; if (socket.connected) { // Do something... } });

For some reason, they're using a plain object instead of an array to store the socket IDs.

34977826 0 Geolocation doesn't work with cordova

I'm currently working on a mobile application with Intel XDK (In background it's Cordova finally, that's why I put Cordova in title.)

With an Ajax request, I get some adresses and with these adresses I want to calculate the distance between them and the current position of user.

So, I get adresses, I convert them and I make the difference.

But actually, nothing is working !

function codeAddress(id, addresse) { geocoder.geocode( { 'address': addresse}, function(results, status) { if (status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) { setTimeout(function(){}, 100); } console.log(id); console.log(addresse); //document.addEventListener("intel.xdk.device.ready",function(){ if (navigator.geolocation) { if (status == google.maps.GeocoderStatus.OK) { navigator.geolocation.getCurrentPosition(function(position) { addressEvent = results[0].geometry.location; var pos = { lat: position.coords.latitude, lng: position.coords.longitude }; var position = new google.maps.LatLng(pos.lat, pos.lng) var resultat = google.maps.geometry.spherical.computeDistanceBetween(addressEvent, position); console.log(resultat); console.log(addressEvent); console.log(pos); console.log(position); var convert = Math.floor(resultat); var finalConvert = convert + " m"; var distance = document.createElement('span'); distance.innerHTML = finalConvert; distance.className = "geo"; document.getElementsByClassName('meta-info-geo')[id].appendChild(distance); }, function() { handleLocationError(true, infoWindow); }); } } //},false); }); }

In the console.log(id), console.log(addresse), I HAVE results !

Actually i'm getting 4 IDs and 4 adresses.

I checked on all the topics I could find on StackOverFlow, and I had normally to add the line in // with the addEventListener but it changes nothing.

Is there someone who knows how to change that ?

ps : Of course, cordova geoloc is in the build and permissions are granted !

This sequence of commands clones your GitHub repository (or any other repository if you change the URL) to ~/local-repos, initializes an empty repository in ~/remote-repos.git and pushes from ~/local-repos to ~/remote-repos.git all branches.

git clone 'https://github.com/nhnc-nginx/apache2nginx' ~/local-repos git init --bare ~/remote-repos.git cd ~/local-repos git remote add mirror-server ~/remote-repos.git git push --mirror mirror-server

Later you update tracking branches (and get new ones) in your ~/local-repos with git fetch origin executed inside ~/local-repos. You can mirror everything to ~/remote-repos.git again with git push --mirror mirror-server. If you want to push a single branch (e.g. origin/gh-pages), use git push mirror-server origin/gh-pages.

Notice that https://github.com/nhnc-nginx/apache2nginx remote is named origin automatically. git fetch origin fetches accessible objects from origin repository and stores branches as tracking branches. Tracking branches are prefixed with the remote name (origin in this case). If you perform git checkout gh-pages and no gh-pages branch exists, Git performs git branch --track gh-pages origin/gh-pages before performing the checkout, which creates the gh-pages branch with upstream set to origin/gh-pages.

This was probably the source of the errors your Git reported. You fetched just origin/gh-pages and tried to push non-existent gh-pages branch. As part of checkout, gh-pages was created, so push work then.

Also notice that you are creating a mirror of your local repository, not origin. If you want to mirror your GitHub repository, you should execute git fetch origin inside the just created empty mirror with git remote add origin 'https://github.com/nhnc-nginx/apache2nginx'.

8857572 0 Prolog - Help fixing a rule

I have a database full of facts such as:

overground(newcrossgate,brockley,2). overground(brockley,honoroakpark,3). overground(honoroakpark,foresthill,3). overground(foresthill,sydenham,2). overground(sydenham,pengewest,3). overground(pengewest,anerley,2). overground(anerley,norwoodjunction,3). overground(norwoodjunction,westcroydon,8). overground(sydenham,crystalpalace,5). overground(highburyandislington,canonbury,2). overground(canonbury,dalstonjunction,3). overground(dalstonjunction,haggerston,1). overground(haggerston,hoxton,2). overground(hoxton,shoreditchhighstreet,3).

example: newcrossgate to brockley takes 2 minutes.

I then created a rule so that if I enter the query istime(newcrossgate,honoroakpark,Z). then prolog should give me the time it takes to travel between those two stations. (The rule I made is designed to calculate the distance between any two stations at all, not just adjacent ones).

istime(X,Y,Z):- istime(X,Y,0,Z); istime(Y,X,0,Z). istime(X,Y,T,Z):- overground(X,Y,Z), T1 is T + Z. istime(X,Y,Z):- overground(X,A,T), istime(A,Y,T1), Z is T + T1. istime(X,Y,Z):- overground(X,B,T), istime(B,X,T1), Z is T + T1.

it seems to work perfectly for newcrossgate to the first couple stations, e.g newcrossgate to foresthill or sydenham. However, after testing newcrossgate to westcroydon which takes 26mins, I tried newcrossgate to crystalpalace and prolog said it should take 15 mins...despite the fact its the next station after westcroydon. Clearly somethings wrong here, however it works for most of the stations while coming up with a occasional error in time every now and again, can anyone tell me whats wrong? :S

Because AJAX always make request & wait response from server, we must put HTML file to web server (Apache HTTP server or NGINX), AJAX will run.

31139129 0

I use process.on(uncaughtException), because all you're really trying to do is catch the output from the error and shut the server down gracefully (and then restart). I don't see any reason to do anything more complicated than that, because by nature of the exception, you don't want your application doing anything else in that state other than shutting down.

Domains are an alternative way of dealing with this, but it's not necessarily better than using the process handler, because you're effectively writing custom logic to handle things that you aren't anticipating. It does give you finer granularity in terms of what your error handler does for different error types, but ultimately you're still potentially running your application in an unknown state after handling it. I'd rather have my application log the exception, shut down, and then i'll fix the error so it never happens again, rather than risking my user's data on a domain solution which may or may not have handled the error correctly, depending on the nuance of the error it encountered.

4508743 0 jQuery doesn't return any API results in the Succes function of $.ajax() while using JSONP

I'm having a lot of trouble getting any results out of the JSONP datatype of the jQuery $.ajax() function. This is my jQuery code:

 $('#show_tweets').click(function(){ $.ajax({ type: 'get', url: 'http://api.twitter.com/1/statuses/user_timeline.json?screen_name=jquery', dataType: 'jsonp', succes: function(data) { $.each(data, function() { $('<div></div>') .hide() .append('<img src="'+ this.profile_image_url +'"/>') .append('<p>'+ this.text +'</p>') .appendTo('#tweets_gallery') .fadeIn(); }) }, error: function() { alert('Iets gaat fout!!'); } }); });

I've assigned the #show_tweets ID to a P tag. #tweets_gallery is an empty DIV. Now, I know I could also use the $.getJSON() function, but I just want to know how I can properly retrieve JSONP results with a $.ajax() request. I've clicked several times and it doesn't output anything.

Thanks in advance!

6047724 0 PDO fetchAll array to one dimensional

this may be a simple question but am struggling to understand how to solve it. I have a form which allows the user to select either "custom" or "all" staff" to assign to a job.

If custom is selected the user selects staff by clicking each checkbox, I then insert these into a jobs table. This produces the array below (3, 1, 10 are the staff IDs)

Array ( [0] => 3 [1] => 1 [2] => 10 )

If "all staff" is selected, I first query a select statement to get all the staff ID's from the staff table, and then insert these into the job table the same as above. However this produces the array :

Array ( [0] => Array ( [staffID] => 1 [0] => 1 ) [1] => Array ( [staffID] => 23 [0] => 23 ) [2] => Array ( [staffID] => 26 [0] => 26 ) [3] => Array ( [staffID] => 29 [0] => 29 ) )

How can I convert the array above to the first array shown?

I'm using the code below to query the database to get all the staff ID's and then inserting them.

 $select = $db->prepare("SELECT staffID FROM staff"); if($select->execute()) { $staff = $select->fetchAll(); } for($i = 0; $i<count($staff); $i++) { $staffStmt = $db->prepare("INSERT INTO staffJobs (jobID, userID) VALUES (:jobID, :staffID)"); $staffStmt->bindParam(':jobID', $jobID, PDO::PARAM_INT); $staffStmt->bindParam(':staffID', $staff[$i], PDO::PARAM_INT); $staffStmt->execute(); }

The first array inserts fine, however the last array inserts zeros for the staffID.

Any suggestions?

Thanks =).

The default dxSlideOut item template does not support the 'icon' field. So, you can use the menuTemplate option to define icon for a menu item.

Is "05 - Listen to the Man_[plixid.com]" an asset within your project? If not I believe that's why this won't work. I'm pretty sure Resources.Load is just for loading your existing assets into RAM, so that they're ready when you need them.

13424379 0 How do I get browsers to trust self-signed certificates for testing? Website address is slightly different than fully qualified domain name

I have a website that is being configured with SSL, and I am using a self-signed certificate for testing purposes, for now. The machine is running Windows 2008 R2 with IIs 7.5 and Apache Tomcat 5.5.

The problem is FireFox is gives the error that the connection is untrusted because it's a self-signed certificate and it also says that the site is using an invalid security certificate. I tried importing the certificate into Firefox, to remedy the situation, and it did not help. However, with IE, exporting the certificate from IIS and importing it into the browser's Trusted Root Certificate Authorities store permitted IE to trust the self-signed certificate.

It's important to note that the server's fully qualified domain name is webdev.dev.mysite.com, whereas the website address is webdev.mysite.com and I've had no problems with the site under HTTP. And with the help of the site here, I setup the self-signed certificate such that it's name is webdev.mysite.com.

How can I get Firefox to trust the self-signed certificate?

Thank you very much for any help.

I managed to sort this so including the answer for anyone else who runs into this error message.

The error: unexpected TOK_IDENT basically means that a field referenced in the query doesn't exist in the index.

The best way to verify what's in your index is to run the Sphinx CLI using:

mysql -P9306 --protocol=tcp --prompt='sphinxQL> '

And run a SELECT * query like:

SELECT * FROM your_index_core WHERE sphinx_deleted = 0 LIMIT 0, 20;

From here you can see the fields in the index across the top.

I can't figure out why they didn't exist in the index - I'd ran rake ts:rebuild multiple times to no avail. In the end I had to stop searchd, manually delete the configuration file and indexes and rebuild from scratch.

You would indeed use whatever server side configuration options are available to you.

Depending on how your hosting is set up you could either modify the include path for PHP (http://php.net/manual/en/ini.core.php#ini.include-path) or restricting the various documents/directories to specific hosts/subnets/no access in the Apache site configuration (https://httpd.apache.org/docs/2.4/howto/access.html).

If you are on shared hosting, this level of lock down isn't usually possible, so you are stuck with using the Apache rewrite rules using a combination of a easy to handle file naming convention (ie, classFoo.inc.php and classBar.inc.php), the .htaccess file and using the FilesMatch directive to block access to *.inc.php - http://www.askapache.com/htaccess/using-filesmatch-and-files-in-htaccess/

FWIW all else being equal the Apache foundation says it is better/more efficient to do it in server side config vs. using .htaccess IF that option is available to you.

Google has actually since added a method for receiving bounced messages via an HTTP Request. It requires adding to your app.yaml:

inbound_services: - mail_bounce

Which will cause a request to hit /_ah/bounce each time a bounce is received. You can then handle the bounce by adding a handler for it. See the section there on Handling Bounce Notifications for more details on how to glean the additional information from those requests.

In order to be able to use DMA, the buffers should be in page-locked memory. AMD and NVIDIA state in their programming guide that to have a buffer in page-locked memory it should be created with the CL_MEM_ALLOC_HOST_PTR flag. Here is what NVIDIA says in the section 3.3.1 of its guide:

OpenCL applications do not have direct control over whether memory objects are allocated in page-locked memory or not, but they can create objects using the CL_MEM_ALLOC_HOST_PTR flag and such objects are likely to be allocated in page-locked memory by the driver for best performance.

Note the "likely" in bold.

Which OS? NVIDIA doesn't speak about the OS so any OS NVIDIA provides drivers for (the same for AMD).
Which Hardware? Any having DMA controller I guess.

Now to write only a part of a buffer you could have a look to the function:

clEnqueueWriteBufferRect()

This function allow to write to a 2 or 3D region of a buffer. Another possibility would be to use sub buffers creating them with the function:

clCreateSubBuffer()

However there is no notion of 2D buffer with it.

You could either use setInterval:

window.setInterval(jTTrackPage, 10000); // call it every 10 000 ms = 10 s

or setTimeout:

function trackPage() { jTTrackPage(); window.setTimeout(trackPage), 10000); // call the function again in 10 000 ms } trackPage();

The difference between both is that the first one calls it every 10s, and if one call takes more than 10s (unlikely here) the next one will be triggered just after, without waiting 10s. The second solution solves this problem.

You can clear an interval or a timeout using respectively clearInterval and clearTimeout:

var interval = window.setInterval(jTTrackPage, 10000); window.clearInterval(interval); // <-- stop it var timeout = window.setTimeout(trackPage, 10000); window.clearTimeout(timeout); // <-- stop it

Swift is designed to take advantage of optional value's and optional unwrapping.

You could also declare the array as nil, as it will save you a very small (almost not noticable) amount of memory.

I would go with an optional array instead of an array that represents a nil value to keep Swift's Design Patterns happy :)

I also think

if let children = children { }

looks nicer than :

if(children != nil){ }

22412698 0 Optimizing hand-evaluation algorithm for Poker-Monte-Carlo-Simulation

I've written an equilator for Hold'em Poker as a hobbyproject. It works correctly, but there is still one thing I am not happy with: In the whole process of simulating hands, the process of evaluating the hands takes about 35% of the time. That seems to be pretty much to me compared with what else has to be done like iterating through and cloning large arrays and stuff.

Any idea of how to get this more performant would be great.

This is the code:

 private static int getHandvalue(List<Card> sCards) { // --- Auf Straight / Straight Flush prüfen --- if ((sCards[0].Value - 1 == sCards[1].Value) && (sCards[1].Value - 1 == sCards[2].Value) && (sCards[2].Value - 1 == sCards[3].Value) && (sCards[3].Value - 1 == sCards[4].Value)) { if ((sCards[0].Color == sCards[1].Color) && (sCards[1].Color == sCards[2].Color) && (sCards[2].Color == sCards[3].Color) && (sCards[3].Color == sCards[4].Color)) return (8 << 20) + (byte)sCards[0].Value;

This method returns an exact value for every sorted 5-Card-Combination in poker. It gets called by another method:

 private static int getHandvalueList(List<Card> sCards) { int count = sCards.Count; if (count == 5) return getHandvalue(sCards); int HighestValue = 0; Card missingOne; int tempValue; for (int i = 0; i < count - 1; i++) { missingOne = sCards[i]; sCards.RemoveAt(i); tempValue = getHandvalueList(sCards); if (tempValue > HighestValue) HighestValue = tempValue; sCards.Insert(i, missingOne); } missingOne = sCards[count - 1]; sCards.RemoveAt(count - 1); tempValue = getHandvalueList(sCards); if (tempValue > HighestValue) HighestValue = tempValue; sCards.Add(missingOne); return HighestValue; }

This recursive method returns the highest value of all possible 5-card-combinations. And this one gets called by the final public method:

 public static int GetHandvalue(List<Card> sCards) { if (sCards.Count < 5) return 0; sCards.Sort(new ICardComparer()); return getHandvalueList(sCards); }

It gets delivered a maximum of 7 cards.

Update

So far: Each time, the public function gets called with 7 cards (which is the case most of the time), it has to call the hand-evaluation method 21 times (one time for every possible 5-card-combo).

I thought about caching the value for each possible set of 5 to 7 cards in a hashtable und just look it up. But if I am not wrong, it would have to store more than 133.784.560 32-bit-integer values, which is about 500MB.

What could be good hashfunction to assign every possible combination to exactly one arrayindex?

Created a new question on that: Hashfunction to map combinations of 5 to 7 cards

Update: For further improvement regarding the accepted answer, have alook at: Efficient way to randomly select set bit

27426305 0 Edmodo android image cropper, fix aspect ratio

I've some problem using edmodo/cropper library on android lollipop. My app should take some pictures, and after each picture is taken, user should crop a square image. this is my layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <com.example.newapicamera.AutoFitTextureView android:id="@+id/texture" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_above="@+id/footer" /> <com.edmodo.cropper.CropImageView xmlns:custom="http://schemas.android.com/apk/res-auto" android:id="@+id/CropImageView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_above="@+id/footer" android:visibility="invisible" /> <ImageView android:id="@+id/footer" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:src="@drawable/footer" /> <TextView android:id="@+id/current_picture" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:textColor="#FFFFFF" android:textSize="30sp" />

and this is how i launch library for crop after picture is taken;

crop_view.setImageBitmap(bitmap); mCameraDevice.close(); mTextureView.setVisibility(View.INVISIBLE); crop_view.setVisibility(View.VISIBLE); DisplayMetrics displayMetrics = getResources().getDisplayMetrics(); int dpWidth = displayMetrics.widthPixels; crop_view.setFixedAspectRatio(true); crop_view.setAspectRatio(dpWidth, dpWidth);

I have the sequent problem:

with this code, the crop is a stripe high as screen
if i remove fixed aspect ratio, the aspect ratio i've is ignored, and i obtain a rectangular crop. So, how can i do to force crop to a square?

The characters that represent decimal digits are laid out in ASCII space in numerical order.

'0' is ASCII 0x30
'1' is ASCII 0x31
'2' is ASCII 0x32
and so on.

This means that you can simply subtract '0' from your character to get the value you desire.

char a = ...; if (a >= '0' && a <= '9') { int digit = a - '0'; // do something with digit }

20298283 0 MVVM approach, what's a good way? How to improve/speed up development?

this post is meant to have a list of suggestions on MVVM approach... What tools do you use, what do you do to speed up development, how do you maintain your application, any special ways of finding defects in this design pattern......

here is what I do:

So first i create my model/db with EF.

Then I create Views (either user controls or windows) with their respective viewmodel. I usually place the viewmodel in the same location as my view. But while starting the name of my view with "UC-name", I call my viewmodel just "name-model".

In my viewmodel I implement InotifyPropertyChanged

in my xaml view I have a resource of my viewmodel, and bind my grids/controls via the itemsource to the staticresource.

I try to do a lot of front end logic with triggers and styles and also place some code in the xaml.cs file if it regards logic for behaviour of my controls.

I can reach my viewmodel from my view (xaml + xaml.cs).

for communiation between viewmodels I use MVVM lights.

that's pretty much it.

Things I'm thinking about

I'm thinking of using T4 templates for generating viewmodel/view. What do you guys think of this. is this worth it?
when using MVVM light Messenger, we get a subscription based communication, and sometimes I find it hard to track what has changed in my DataContext. Any suggestions on this?
any other improvements or suggestions are more than welcome !

Straight from Phonegap website -

PhoneGap is an HTML5 app platform that allows you to author native applications with web technologies and get access to APIs and app stores.

What this means is it is not browser dependent. The code compiles to native application. You don't need a browser to run it.

You could use a make file to generate the .i files first, run your processing on them, then compile them.

There have been numerous posts on here about trying to do OCR on camera generated images. The problem is not that the resolution is too low, but that its too high. I cannot find a link right now, but there was a question a year or so ago where in the end, if the image size was reduced by a factor of four or so, the OCR engine worked better. If you examine the image in Preview, what you want is the number of pixels per character to be say 16x16 or 32x32, not 256x256. Frankly I don't know the exact number but I'm sure you can research this and find posts from actual framework users telling you the best size.

Here is a nice response on how to best scale a large image (with a link to code).

8302923 0 new created UIImageViews do not show up when added as subview

upon a tap, I want to let a few UIImageView objects appear on an underlaying UIView. So I created the following action:

- (IBAction)startStars: (id) sender { UIView* that = (UIView*) sender; // an UIButton, invisible, but reacting to Touch Down events int tag = that.tag; UIView* page = [self getViewByTag:mPages index:tag]; // getting a page currently being viewed if ( page != nil ) { int i; UIImage* image = [UIImage imageNamed:@"some.png"]; for ( i = 0 ; i < 10 ; ++i ) { // create a new UIImageView at the position of the tapped UIView UIImageView* zap = [[UIImageView alloc] initWithFrame:that.frame]; // assigning the UIImage zap.image = image; // make a modification to the position so we can see all instances CGPoint start = that.layer.frame.origin; start.x += i*20; zap.layer.position = start; [page addSubview:zap]; // add to the UIView [zap setNeedsDisplay]; // please please redraw [zap release]; // release, since page will retain zap } [image release]; } }

Unfortunately, nothing shows up. The code gets called, the objects created, the image is loaded, even the properties are as expected. Page itself is a real basic UIView, created with interface builder to contain other views and controls.

Still, nothing of this can be seen....

Has anyone an idea what I am doing wrong? Do I need to set the alpha property (or others)?

Thanks

You can use:

private float x; public float X { get { return x; } }

Now you only set x from within your class.

Famous Game of Life seems to be a good idea. Cells are persistence units, JSF, web beans + ejb to display the working area, scheduled beans - to put it in motion. Game's logic can be implemented in EJB or JMS (or even both). You could extend original logic, introduce new objects or rules and finally get Nobel prize for achievements in social modeling :)

Add @Key(types=String.class) @Value(types=String.class)

since "Properties" is a bit of a hack in that it can also contain non-String, and doesn't allow generic specification so you need to restrict it. The next version of AppEngine will have a version of DataNucleus that doesn't require this additional info.

Is there a way to override java.io.File to perform the file path translation with custom code? In this case, I would translate the remote paths to a mount point

Yes, you can perform your own implementation of java.io.File and place it in a separate jar and then load it instead of the real java.io.File.

To have the JVM load it you can either use the java.endorsed.dirs property or java -Xbootclasspath/p:path option in the java launcher ( java )

BUT!!!

Creating your own version of the java.io.File class won't be as easy as modifying the legacy source code.

If you're afraid of breaking something you could first extract all your hardcoded paths to use a resource bundle:

So:

 File file = new File("C:\\Users\\oreyes\\etc.txt");

Would be:

File file = new File( Paths.get( "user.dir.etc" ));

And Paths would have a resource bundle internally

class Paths { private static ResourceBundle rs = ResourceBundle.getBundle("file.paths"); public static String get( String key ) { rs.getString( key ); } }

You can have all this hardcoded paths extraction with an IDE ( usually an internationalization plugin )

Provide a different resource bundle for Linux and your done. Test and re-test and re-test

So, use provide your own java.io.File only as a last resource.

18670565 1 Why __init__ in python fail

I'm using python2.7 to define a function like this

def foo(*args, **kwargs): print 'args = ', args print 'kwargs = ', kwargs print '---------------------------------------'

and by calling foo(3), the output is as the following:

args = (3,) kwargs = {}

which is desired.

But as for __init__ function in a class in which the parameters are the same form as foo, I can't instantize the class Person by invoking Person(3)

def Person(): def __init__(self, *args, **kwargs): print args print kwargs x = Person(3)

The output is

 x = Person(3) TypeError: Person() takes no arguments (1 given)

That confused me a lot, have I missed something?

There are several problems you need to address — both in your code and both in your current knowledge :-) Start with this:

Read a few articles about ASP.NET's page life-cycle, so you become more familiar with what to do in each life-cycle event handler (OnInit, OnLoad, …). Good starting point might be this MSDN overview. However, google for “ASP.NET page life cycle” and read a few other articles and examples as well.

Also, you will need to get familiar with the request-response nature of ASP.NET page processing. In the beginning, bear in mind that when the user hits some 'Submit' button which in turn causes an HTTP POST request to occur, you are responsible to creating the page's control tree to match its structure, IDs, etc. as they were in the previous request. Otherwise ASP.NET doesn't know how in which controls to bind the data the user filled-in.
Near the line tagged //Lost and confused here :/ you are creating a new control and immediately querying it for the 'results' (which I expect to be values of some edit boxes within it). This cannot work, because it's most probably too early for the form to have the data received from the Page object that drives the request processing.
Your Results property is poorly designed. First, you shouldn't be using properties that actually 'generate' data in such a way they can change without notice. Properties shall be used as “smart fields”, otherwise you end up with less manageable and less readable code. Second, the setter you left there like “set;” causes any value assigned into the property to be actually lost, because there's no way to retrieve it. While in some rare cases this behavior may be intentional, in your case I guess it's just an error.

So, while you can currently leave behind any “good OOP way” to approach your problem, you certainly should get more familiar with the page life-cycle. Understanding it really requires some thinking about the principles how ASP.NET web applications are supposed to work, but I'm sure it will provide you with the kick forward you actually need.

UPDATE: In respect to Tony's code (see comments) the following shall be done to move the code forward:

The list of form data in the requestForm property shall have tuple of [form ASCX path, control ID, the actual RequestForm data class]
GatherForms shall be called only when the page is initially loaded (i.e. if (Page.IsPostBack)) and it shall fill requestForm with the respective tuples for available ASCX forms.
Both chklApplications and wizard steps shall be created in LoadForms on the basis of requestForm's content.
When results are to be gathered, the ID stored in the respective requestForm entry can be used to look-up the actual user control.

23061804 0 Optimizing MySQL self-join query

This is the explain of the query:

Even if from this it doesn't seem a problematic query, in my machine it takes more or less 69 seconds with MyIsam and 56 seconds in InnoDB. The table has more or less 1 thousand records. As you can see from the explain I have indeces both on the actor column, on the ip column and even on both columns. I have mysql version 5.5.35.

Do you have any idea on why this query takes so long? How can I optimize it?

33198428 1 jwt: 'module' object has no attribute 'encode'

I am getting Module not found error when using jwt. Here is how I declared it:

The error message says encode is not found in jwt. I did a tab on jwt and found that the encode is a method inside jwt.JWT. I tried changing it to

jwt_string = jwt.JWT.encode(payload, shared_key)

and it gives an error "unbound method encode() must be called with JWT instance as first argument (got dict instance instead)"

There are wrappers to inotify that make it easy to use from high-level languages. For example, in ruby you can do the following with rb-inotify:

notifier = INotify::Notifier.new # tell it what to watch notifier.watch("path/to/foo.txt", :modify) {puts "foo.txt was modified!"} notifier.watch("path/to/bar", :moved_to, :create) do |event| puts "#{event.name} is now in path/to/bar!" end

There's also pyinotify but I was unable to come up with an example as concise as the above.

For the XSLT part I recommend using the "Fill-in the blasnks" technique -- see a simple example here: http://stackoverflow.com/a/8674694/36305.

The form skeleton will look like this:

<form name="formRoot" xmlns:gen="my:gen"> <gen:name/> </form>

The XSLT code will contain a template matching gen:name that produces:

<p>Name</p><input name="name" value="Name"/>

The URL to the form-skeleton is passed as an external parameter to the XSLT transformation.

The source XML document (URL or itself) is passed as another external parameter.

Thus the XSLT transformation can process any source XML document and insert the results of processing into any form-skeleton document.

java.lang.NoSuchMethodException: <init> [class android.content.Context, interface android.util.AttributeSet]

Your HackySwipeBackLayout is missing a constructor:

public HackySwipeBackLayout(Context context, AttributeSet attrs) { super(context, attrs); }

If you look more closely at the HackyViewPager, you'll notice that it is in there too. As a matter of fact, any view that needs to support inflating from xml should have this constructor defined. You may find the documentation on how to create custom views helpful too.

Edit: since your intention is to catch the exception thrown, make sure to catch the ArrayIndexOutOfBoundsException accordingly:

@Override public boolean onInterceptTouchEvent(MotionEvent ev) { try { return super.onInterceptTouchEvent(ev); } catch (ArrayIndexOutOfBoundsException e) { e.printStackTrace(); return false; } }

That should stop your app from crashing on this particular exception, but is of course not a 'fix' for the underlying issue that is causing the ArrayIndexOutOfBoundsException to be thrown in the first place. It may or may not lead to the desired behaviour. Either way, consider opening a ticket with the maintainer of the SwipeBack repo.

The dot is your current directory, and this tells Bash to use adb from there.

Otherwise, you can add platform-tools to your PATH, by placing a line like this in your ~/.profile or ~/.bash_profile, then re-starting the Terminal. On Linux, you might want to modify ~/.bashrc instead, depending on what is used.

export PATH=/Users/espireinfolabs/Desktop/soft/android-sdk-mac_x86/platform-tools:$PATH

If you've installed the platform tools somewhere else, change the path accordingly. For Android Studio on OS X, for example, you'd use the following—note the double-quotes that prevent a possible space from breaking the path syntax:

export PATH="/Users/myuser/Library/Android/sdk/platform-tools":$PATH

So this is known that it was due to space next to %d in loop. Can someone explain Carriage Return in a little detail, I searched but could not understand exactly what that is.

22460842 0 MySQL Query To Produce Output Per Month Based On Variable Duration Entries

Ok, so I have a table that contains payments associated with dates and durations.

Example data:

purchase_id date_purchased user_id duration (in months) amount_income 1 2013-12-28 00:00:00 1 2 £15 2 2014-01-04 00:00:00 2 1 £10 3 2014-02-04 00:00:00 3 6 £40

*So the longer duration users pay for, the less they pay per month overall.

What I'm trying to display is the total income per month based on this table. So a payment of £15 over 2 months would mean £7.50 income per month for 2 months.

Sample output:

Month Amount 2013-12 £7.50 2014-01 £17.50 2014-02 £6.66 2014-03 £6.66 2014-04 £6.66 2014-05 £6.66 2014-06 £6.66 2014-07 £6.66

This output corresponds to the sample input above. Hopefully it clarifies the breakdown of the income per month.

Any ideas how to do this in a query?

24432502 0 Force Storyboard to present specific base localization

I have a story board with base localisation (The story board itself is not localised) I wish to use base locazation to localize the app and still to be able to change the localization from within the app itself.

Right now I am dong so with this approach -

+(NSString*)localizedStringForKey:(NSString*) key { NSBundle* languageBundle = [self localizationBundle]; NSString* str=[languageBundle localizedStringForKey:key value:@"" table:nil]; return str; }

But this works only for dynamic strings that I assign in the code. Is there any way to force the story board to use specific base localizatio or should I give up using this option and create all the strings in code ?

Thanks SHani

Are you able to sort the group in Descending order? I have an idea but it will be less work for you if they're grouped newest to oldest.

WhileReadingRecords:

In each group you'll need to determine the 1st and 6th visit. (You're currently suppressing any groups with less than 6.) To do this, I would make a Shared Variable called Counter that increments by one every record and resets every time it reaches a new group. (Set it to zero in the Group Header.)

Next you'll need two more Shared Variables called FirstDate and SixthDate. These populate with the date value if Counter equals one or six respectively. Just like Counter you'll reset these every time the group changes.

WhilePrintingRecords:

If everything works, you should now have the two dates values you need for calculations. Add an additional clause in your current Suppression formula:

.... AND DateDiff("d", FirstDate, SixthDate)

Most likely it does not work because of your match pattern:

the {R:1} will only match (.*) in your pattern, and will never match files/123...
URL in match pattern always starts with no leading slash: should be files/\d+... and not /files/\d+...

Try this one instead (works fine for me):

<rule name="1" stopProcessing="true"> <match url="^files/\d+/.*\.html$" /> <action type="Redirect" url="default.aspx?url={R:0}" redirectType="Permanent" /> </rule>

9754228 0 how to initialize private members of class in c++

Hi i have a c++ class with some private members as follows

 template <typename V, typename E> class Vertex { public: Vertex(); ~Vertex(); typedef std::pair<int, E> edgVertPair; typedef std::vector<edgeVertPair> vectEdges; void setVertexID(int data); int getVertexID(); void setEdgeVertPair(int vertID, E edge); edgVertPair getEdgeVertPair(); void setEdgeList(edgeVertPair edgeVert); vectEdges getEdgeList(); private: int vertexID; edgVertPair evp; vectEdges edgeList; };

Now i want to create a pair i.e. something like

evp.first="someint"; evp.second="somestring";

and then push this evp into the edgeList i.e. edgeList.push_back(evp); Now the problem is in the setter function i did something like this:

 template<typename V, typename E> void Vertex<V, E>::setEdgeVertPair(int vertID, E edge){ ...populate evp;... }

now i don't know how to populate the evp pair with vertID, edge.

Well, it turned out to be simpler than I thought. I decided to read the code of the plugin and modify it by commenting out the code that sorts my output.

That is when I found a variable 'sortResults:true' in defaults. So, all I needed was to set that variable to false. I didn't find this in the documentation though.

$('#search').autocomplete ( { url: "index.php", sortResults: false } )

Now the output is in the exact order that I require.

I got the idea of reading the code to find/solve the problem from here : jQuery "Autocomplete" plugin is messing up the order of my data (That isn't the same plugin)

Thanks. :)

You have a couple of choices. You can isolate the common functionality into a third object that Class1 and Class2 share (aggregation), or you can actually create a hierarchy of objects (inheritance). I'll talk about inheritance here.

JavaScript doesn't have classes, it's a prototypical language. An object instance is "backed" by a prototype object. If you ask the instance for a property it doesn't have (and functions are attached to objects as properties), the JavaScript interpreter checks the prototype behind the object to see if it has the property (and if not, the prototype behind that object, etc., etc.). This is how prototypical inheritance works.

JavaScript is an unusual prototypical language in that, until recently, there was no way to create an object and assign its prototype directly; you had to do it through constructor functions. If you're using class-based terminology, you're probably going to be more comfortable with constructor functions anyway. :-)

Here's a basic inheritance setup (this is not how I would actually do this, more on that below):

// Constructs an Vehicle instance function Vehicle(owner) { this.owner = owner; } // Who's this Vehicle's owner? Vehicle.prototype.getOwner = function() { return this.owner; }; // Constructs a Car instance function Car(owner) { // Call super's initialization Vehicle.call(this, owner); // Our init this.wheels = 4; } // Assign the object that will "back" all Car instances, // then fix up the `constructor` property on it (otherwise // `instanceof` breaks). Car.prototype = new Vehicle(); Car.prototype.constructor = Car; // A function that drives the car Car.prototype.drive = function() { };

Now we can use Car and get the features of Vehicle:

var c = new Car("T.J."); alert(c.getOwner()); // "T.J.", retrived via Vehicle.prototype.getOwner

The above is a bit awkward and it has a couple of issues with when things happen that can be tricky. It also has the problem that most of the functions are anonymous, and I don't like anonymous functions (function names help your tools help you). It's also awkward to call your prototype's version of a function if you also have a copy of it (e.g., a "supercall" — not an uncommon operation with hierarchies). For that reason, you see a lot of "frameworks" for building hierarchies, usually using class-based terminology. Here's a list of some of them:

The Class feature of Prootype, a general-purpose JavaScript library
Dean Edwards' base2
John Resig's Simple JavaScript Inheritance (Resig being the person who created jQuery)
Er, um, mine — which as far as I know is being used by about three people. I did it because I had issues with decisions each of the above made. I will be updating it to not use class terminology (and actually releasing it as a tiny library, rather than just a blog post), because none of these adds classes to JavaScript, and acting as though they do misses the point of JavaScript prototypical model.

Of those four, I'd recommend Resig's or mine. Resig's uses function decompilation (calling toString on function instances, which has never been standardized and doesn't work on some platforms), but it works even if function decompilation doesn't work, it's just slightly less efficient in that case.

Before jumping on any of those, though, I encourage you to look at the true prototypical approach advocated by Douglas Crockford (of JSON fame, also a big wig at YUI). Crockford had a great deal of input on the latest version of ECMAScript, and some of his ideas (most notably Object.create) are now part of the latest standard and are finding their way into browsers. Using Object.create, you can directly assign a prototype to an object, without having a constructor function.

I prefer constructor functions (with my syntactic help) for places where I need inheritance, but Crockford's approach is valid, useful, and gaining popularity. It's something you should know about and understand, and then choose when or whether to use.

To initialize many contacts in a loop you may want to do something like this:

Contact *FirstOne = new Contact(); Contact *current = FirstOne; while(...) { current->next = new Contact(); current = current->next; //do stuff to current, like adding info }

That way you are building up your Contact list. After that *FirstOne ist the first and *current is the last element of your list. Also you may want to make sure that the constructor sets *next to NULL to detect the end of the list.

13687738 0 OpenRasta Unit Testing GET results in 404 error

I've completed my implementation of my first OpenRasta RESTful webservice and have successfully got the GET requests I wish for working.

Therefore I've taken some 'inspiration' from Daniel Irvine with his post http://danielirvine.com/blog/2011/06/08/testing-restful-services-with-openrasta/ to built a automated test project to test the implmentation.

I've created my own test class but I'm constantly getting a 404 error as the reponse status code.

using System; using System.Collections.Generic; using System.Linq; using System.Text; using OpenRasta.Hosting.InMemory; using PoppyService; using OpenRasta.Web; using System.IO; using System.Runtime.Serialization.Json; using Microsoft.VisualStudio.TestTools.UnitTesting; using NUnit.Framework; namespace PoppyServiceTests { //http://danielirvine.com/blog/2011/06/08/testing-restful-services-with-openrasta/ [TestFixture] class OpenRastaJSONTestMehods { [TestCase("http://localhost/PoppyService/users")] public static void GET(string uri) { const string PoppyLocalHost = "http://localhost/PoppyService/"; if (uri.Contains(PoppyLocalHost)) GET(new Uri(uri)); else throw new UriFormatException(string.Format("The uri doesn't contain {0}", PoppyLocalHost)); } [Test] public static void GET(Uri serviceuri) { using (var host = new InMemoryHost(new Configuration())) { var request = new InMemoryRequest() { Uri = serviceuri, HttpMethod = "GET" }; // set up your code formats - I'm using // JSON because it's awesome request.Entity.ContentType = MediaType.Json; request.Entity.Headers["Accept"] = "application/json"; // send the request and save the resulting response var response = host.ProcessRequest(request); int statusCode = response.StatusCode; NUnit.Framework.Assert.AreEqual(200, statusCode, string.Format("Http StatusCode Error: {0}", statusCode)); // deserialize the content from the response object returnedObject; if (response.Entity.ContentLength > 0) { // you must rewind the stream, as OpenRasta // won't do this for you response.Entity.Stream.Seek(0, SeekOrigin.Begin); var serializer = new DataContractJsonSerializer(typeof(object)); returnedObject = serializer.ReadObject(response.Entity.Stream); } } } }

}

If I navigate to the Uri manually in the browser I'm getting the correct responce and HTTP 200.

It's possibly something to do with my Configuration class, but if I test all the Uris manaully again I get the correct result.

public class Configuration : IConfigurationSource { public void Configure() { using (OpenRastaConfiguration.Manual) { ResourceSpace.Has.ResourcesOfType<TestPageResource>() .AtUri("/testpage").HandledBy<TestPageHandler>().RenderedByAspx("~/Views/DummyView.aspx"); ResourceSpace.Has.ResourcesOfType<IList<AppUser>>() .AtUri("/users").And .AtUri("/user/{appuserid}").HandledBy<UserHandler>().AsJsonDataContract(); ResourceSpace.Has.ResourcesOfType<AuthenticationResult>() .AtUri("/user").HandledBy<UserHandler>().AsJsonDataContract(); ResourceSpace.Has.ResourcesOfType<IList<Client>>() .AtUri("/clients").And .AtUri("/client/{clientid}").HandledBy<ClientsHandler>().AsJsonDataContract(); ResourceSpace.Has.ResourcesOfType<IList<Agency>>() .AtUri("/agencies").And .AtUri("/agency/{agencyid}").HandledBy<AgencyHandler>().AsJsonDataContract(); ResourceSpace.Has.ResourcesOfType<IList<ClientApps>>() .AtUri("/clientapps/{appid}").HandledBy<ClientAppsHandler>().AsJsonDataContract(); ResourceSpace.Has.ResourcesOfType<Client>() .AtUri("/agencyclients").And .AtUri("/agencyclients/{agencyid}").HandledBy<AgencyClientsHandler>().AsJsonDataContract(); ResourceSpace.Has.ResourcesOfType<Client>() .AtUri("/agencyplususerclients/{appuserid}").HandledBy<AgencyPlusUserClientsHandler>().AsJsonDataContract(); ResourceSpace.Has.ResourcesOfType<IList<Permission>>() .AtUri("/permissions/{appuserid}/{appid}").HandledBy<PermissionsHandler>().AsJsonDataContract(); ResourceSpace.Has.ResourcesOfType<IList<Role>>() .AtUri("/roles").And .AtUri("/roles/{appuserid}").And.AtUri("/roles/{appuserid}/{appid}").HandledBy<RolesHandler>().AsJsonDataContract(); ResourceSpace.Has.ResourcesOfType<IList<AppVersion>>() .AtUri("/userappversion").And .AtUri("/userappversion/{appuserid}").HandledBy<UserAppVersionHandler>().AsJsonDataContract(); } } }

Any suggestions would be greatfully received.

Perhaps the most natural thing to do here is to present the login view controller modally. When the user has logged in successfully, the first controller can then push the third view controller onto the navigation stack. This way, the back button will lead directly back to the first view controller, and the user will understand why.

Use 2 variables. First variable will store the last execution date and the next one will store the version. Whenever you execute the script, first check if the date is same. If yes, increment the version else set the version to 1. Export the variables so that they retain their values.

if [ "`date +'%Y%m%d'`" == "$LAST_EXEC_DATE" ]; then (( VERSION += 1 )) else VERSION=1 LAST_EXEC_DATE=`date +"%Y%m%d"` fi export LAST_EXEC_DATE export VERSION

While I adore the grep solution for its elegance and for reminding (or teaching) me about a method in Enumerable that I'd forgotten (or overlooked completely), it's slow, slow, slow. I agree 100% that creating the Array#mode method is a good idea, however - this is Ruby, we don't need a library of functions that act on arrays, we can create a mixin that adds the necessary functions into the Array class itself.

But the inject(Hash) alternative uses a sort, which we also don't really need: we just want the value with the highest occurrence.

Neither of the solutions address the possibility that more than one value may be the mode. Maybe that's not an issue in the problem as stated (can't tell). I think I'd want to know if there was a tie, though, and anyway, I think we can improve a little on the performance.

require 'benchmark' class Array def mode1 sort_by {|i| grep(i).length }.last end def mode2 freq = inject(Hash.new(0)) { |h,v| h[v] += 1; h } sort_by { |v| freq[v] }.last end def mode3 freq = inject(Hash.new(0)) { |h,v| h[v] += 1; h } max = freq.values.max # we're only interested in the key(s) with the highest frequency freq.select { |k, f| f == max } # extract the keys that have the max frequency end end arr = Array.new(1_000) { |i| rand(100) } # something to test with Benchmark.bm(30) do |r| res = {} (1..3).each do |i| m = "mode#{i}" r.report(m) do 100.times do res[m] = arr.send(m).inspect end end end res.each { |k, v| puts "%10s = %s" % [k, v] } end

And here's output from a sample run.

 user system total real mode1 34.375000 0.000000 34.375000 ( 34.393000) mode2 0.359000 0.000000 0.359000 ( 0.359000) mode3 0.219000 0.000000 0.219000 ( 0.219000) mode1 = 41 mode2 = 41 mode3 = [[41, 17], [80, 17], [72, 17]]

The "optimised" mode3 took 60% of the time of the previous record-holder. Note also the multiple highest-frequency entries.

EDIT

A few months down the line, I noticed Nilesh's answer, which offered this:

def mode4 group_by{|i| i}.max{|x,y| x[1].length <=> y[1].length}[0] end

It doesn't work with 1.8.6 out of the box, because that version doesn't have Array#group_by. ActiveSupport has it, for the Rails developers, although it seems about 2-3% slower than mode3 above. Using the (excellent) backports gem, though, produces a 10-12% gain, as well as delivering a whole pile of 1.8.7 and 1.9 extras.

The above applies to 1.8.6 only - and mainly only if installed on Windows. Since I have it installed, here's what you get from IronRuby 1.0 (on .NET 4.0):

========================== IronRuby ===================================== (iterations bumped to **1000**) user system total real mode1 (I didn't bother :-)) mode2 4.265625 0.046875 4.312500 ( 4.203151) mode3 0.828125 0.000000 0.828125 ( 0.781255) mode4 1.203125 0.000000 1.203125 ( 1.062507)

So in the event that performance is super-critical, benchmark the options on your Ruby version & OS. YMMV.

I recommend you start by reading up on computational color theory. Wikipedia is actually a fine place to educate yourself on the subject. Try looking up a color by name on Wikipedia. You will find more than you expect. Branch out from there until you've got a synopsis of the field.

As you develop your analytic eye, focus on understanding your favorite (or most despised) interface colors and palettes in terms of their various representations in different colorspaces: RGB, HSB, HSL. Keep Photoshop/GIMP open so you can match the subjective experience of palettes to their quantifiable aspects. See how your colors render on lousy monitors. Notice what always remains readable, and which color combos tend to yield uncharismatic or illegible results. Pay attention to the emotional information conveyed by specific palettes. You will quickly see patterns emerge. For example, you will realize that high saturation colors are best avoided in UI components except for special purposes.

Eventually, you'll be able to analyze the output of the palette generators recommended here, and you'll develop your own theories about what makes a good match, and how much contrast is needed to play well on most displays.

(To avoid potential frustration, you might want to skip over to Pantone's free color perception test. It's best taken on a color calibrated display. If it says you have poor color perception, then numeric analysis is extra important for you.)

The C++ runtime dlls you need are the ones provided with the compiler as redistributable package and exactly this one! Other redist packages won't necessary work because of the manifests embedded in the executables which require an exact version (checked by a hash value of the binaries in the side by side assembly directory C:\Windows\SxS)

So you are right with the redistributable but you need the one that was installed with the compiler not one from a best guess from the internet. The exact versions can be looked at in the manifest files (XML)

I have finished this, just to let anyone know who may have this problem in the future. It turns out the reason there was nothing being taken in was because ADO tries to determine a column type. If other values in this column are not of said type, it removes them completely.

To counter this, you need to create a schema.ini file, like so:

StreamWriter writer = new StreamWriter(File.Create(dir + "\\schema.ini")); writer.WriteLine("[" + fileToBeRead + "]"); writer.WriteLine("ColNameHeader = False"); writer.WriteLine("Format = CSVDelimited"); writer.WriteLine("CharacterSet=ANSI"); int iColCount = dTable.Columns.Count + 1; for (int i = 1; i < iColCount; i++) { writer.WriteLine("Col" + i + "=Col" + i + "Name Char Width 20"); } //writer.WriteLine("Col1=Col1Name Char Width 20"); //writer.WriteLine("Col2=Col1Name Char Width 20"); //etc. writer.Close();

Thanks for everyone's suggestions!

If you are not locked in to using SWT, you could use the e(fx)clipse e4 renderer for JavaFX instead.

e(fx)clipse has more possibilities to control the lifecycle of the application. For example you can return a Boolean from @PostContextCreate to signal whether you want to continue the startup or not. You will not be able to use EPartService here though, but you can roll your own login dialog using dependency injection as greg-449 has described it in his answer.

public class StartupHook { @PostContextCreate public Boolean startUp(IEclipseContext context) { // show your login dialog LoginManager loginManager = ContextInjectionFactory.make(LoginManager.class, context); if(!loginManager.askUserToLogin()) { return Boolean.FALSE; } return Boolean.TRUE; } }

(You can also restart the application. Form more details see http://tomsondev.bestsolution.at/2014/11/03/efxclipse-1-1-new-features-api-to-restart-your-e4-app-on-startup/).

36632150 0 How to do a partial sum of table rows in LiveCycle - Javascript

I have 4 rows (and 3 columns) in a table. The last row is the total. I need to sum only the first two rows, excluding the last one. The problem is they are all calculated values from different tables, how do I do it? I am new to Adobe LiveCycle and Javascript.

This is what I currently have:

var times = xfa.resolveNodes("Row2[*].Time"); this.rawValue = Calculate.SumRawValues(times);

I am trying something like this:

var times = xfa.resolveNodes("Row2[*].Time"); var timesFlushing = xfa.resolveNode("Row2[2].Time"); this.rawValue = Calculate.SumRawValues(times) - timesFlushing.value;

or something like this:

var times = xfa.resolveNodes("Row2[*].Time"); this.rawValue = Calculate.SumRawValues(times) - xfa.resolveNode("Row2[2].Time");

or even this:

this.rawValue = Row2.Time + xfa.resolveNode("Row2[1].Time")

Clearly I am new to this and none of these work. Help please??? Comments?

However, note that there is no error correction done. You should catch cases, where the input is no integer.

3935900 0 How to commit and rollback transaction in sql server?

I have a huge script for creating tables and porting data from one server. So this sceipt basically has -

Create statements for tables.
Insert for porting the data to these newly created tables.
Create statements for stored procedures.

So I have this code but it does not work basically @@ERROR is always zero I think..

BEGIN TRANSACTION --CREATES --INSERTS --STORED PROCEDURES CREATES -- ON ERROR ROLLBACK ELSE COMMIT THE TRANSACTION IF @@ERROR != 0 BEGIN PRINT @@ERROR PRINT 'ERROR IN SCRIPT' ROLLBACK TRANSACTION RETURN END ELSE BEGIN COMMIT TRANSACTION PRINT 'COMMITTED SUCCESSFULLY' END GO

Can anyone help me write a transaction which will basically rollback on error and commit if everything is fine..Can I use RaiseError somehow here..

Your immediate problem is that you need parentheses around (List.length xs). The code also treats an empty input list as an error in all cases, which is not correct. An empty list is a legitimate input if the desired length k is 0.

Update

You also have one extra parameter in your definition. If you say this:

let myfun k xs = function ...

the function myfun has 3 parameters. The first two are named k and xs and the third is implicitly part of the function expression.

The quick fix is just to remove xs.

I think you might be asking for the wrong number of elements in your recursive call to take. Something to look at anyway.

You can just use Windows Explorer. Open Windows Explorer and go into the assembly folder inside your Windows folder. You should then see all the assemblies that are registered, if you want to add yours in, just drag and drop it in there.

Or if you prefer, you can locate the gacutil.exe and use that to do it (but it's not installed with the framework nowdays, only with the SDK I think).

36075549 0

You should unquote to the true:

if(html==true) //or just, if(html)

Otherwise it will look for string "true" and this is why it goes to the else part.

34970499 0 AWS S3 + CDN Speed, significantly slower

Ok,

So I've been playing around with amazon web services as I am trying to speed up my website and save resources on my server by using AWS S3 & CloudFront.

I ran a page speed test initially, the page speed loaded in 1.89ms. I then put all assets onto an s3 bucket, made that bucket available to cloudfront and then used the cloudfront url on the page.

When I ran the page speed test again using this tool using all their server options I got these results:

Server with lowest speed of : 3.66ms

Server with highest speed of: 5.41ms

As you can see there is a great increase here in speed. Have I missed something, is it configured wrong? I thought the CDN was supposed to make the page speed load faster.

14665748 0 Differences between p-values in summary and from the anova in R lm()

I am seeing differences in the p-value for the anova depending on how I access this.

Is there a way to get the same value that is returned by the summary?

One easy to represent case returns < 2.2e-16 in the summary and in the anova but gives me 8.129959e-100 when I access the value directly:

x <- lm(formula = eruptions ~ waiting, data = faithful) summary(x) anova(x) anova(x)$"Pr(>F)"[1]

In another more difficult to represent case (there is a lot more data) I get p-value: < 2.2e-16 in the summary but 0 from anova.

Is there any way to get the actual value that is returned in the summary and anova?

I really appreciate your help -

you're creating temporary variable a in function calculateFlexibility, then you store pointer to f.flex variable, but after function is ended - a is gone from memory, so your f.flex pointer is now pointing to nowhere

if you want to have really variable length, you should do something like this:

Flexibility calculateFlexibility() { Flexibility f; f.flex = (int*)malloc(....); return f; }

and at the end of program:

free(f.flex);

for proper arguments of malloc I suggest you to read: http://en.cppreference.com/w/c/memory/malloc

Your fetch XML looks correct to me. When you set up the subgrid did you set "Records" = "All Record Types" in the Data Source section? If you did not then the subgrid will append a condition to your fetchxml so that it returns only records related to the specific relationship that you specified.

If you want to create instance of your class from name = Paul AND age = 16 AND country = china that kind of script, then you could create yourself method

public <T> T builder(Class<T> clazz, String line) throws InstantiationException, IllegalAccessException, SecurityException, NoSuchMethodException, IllegalArgumentException, InvocationTargetException { T instance = clazz.newInstance(); String[] exps = line.split("AND"); for (String exp : exps) { String[] tokens = exp.split("=", 2); // TODO check if token has length==2 tokens[0] = tokens[0].trim(); tokens[1] = tokens[1].trim(); String methodName = "set" + (("" + tokens[0].charAt(0)).toUpperCase()) + tokens[0].substring(1); Method m1 = instance.getClass().getMethod(methodName, String.class); m1.invoke(instance, tokens[1]); } return instance; }

and when you call it builder(Person.class,"name = Paul AND age = 16 AND country = china") you will get instance of Person class with populated fields name, age and country.

Is that what you are looking for?

39832012 0 Does gcc use "LD_LIBARRY_PATH" when doing linking '-L'?

I've got libo.a file under current directory, I found I have to use '-L.' to make gcc able to find current directory's archive files.

I know under linux/solaris, there's environment variable of "LD_LIBRARY_PATH" to specify shared_library path. I found it doesn't work with gcc when doing link, 'export LD_LIBRARY_PATH' cannot be used to replace '-L.'

Question(1) Is this by design of gcc, that linker search path doesn't read from environment variable, but should be specified by command line options?

More weird is, I did 'export LIBPATH=.', it doesn't work either, but if I add LIBPATH into a scons file:

Library('o.c') Program('n.c',LIBS=['o'],LIBPATH='.')

Then it works!

Question(2) What is the difference between environment shell variable of 'LIBPATH', and the scons parameter of 'LIBPATH'. Does scons has an internal parameter named 'LIBPATH', which has nothing to do with shell environment?

Thanks!

24956706 0 use *this as std::shared_ptr

here is a "chess++" problem that I'm facing wright now with my nested class, although it may look like some joke, it's not a joke but real problem which I want to either solve or change the way to achieve the same thing in my project.

#include <map> #include <memory> #include <iostream> #include <sigc++/signal.h> class foo { public: struct bar; typedef sigc::signal<void, std::shared_ptr<bar>> a_signal; struct bar { bar() { some_signal.connect(sigc::mem_fun(*this, &foo::bar::func)); } void notify() { some_signal.emit(this); // how to ?? } void func(std::shared_ptr<foo::bar> ptr) { std::cout << "you haxor!" << std::endl; // use the pointer ptr-> } a_signal some_signal; }; std::map<int, std::shared_ptr<bar>> a_map; }; int main() { std::shared_ptr<foo::bar> a_foo_bar; foo foo_instance; foo_instance.a_map.insert(std::pair<int, std::shared_ptr<foo::bar>>(4, a_foo_bar)); foo_instance.a_map.at(0)->notify(); return 0; }

What I want to do here is to emit a signal. the signal is declared as one that triggers a handler that takes a shared_ptr as an argument. the function notify() should convert *this into shared_ptr, how do I do that to make the above code run?

7431908 0 Wifi Device to Device Communication problem

I wrote a code in my application to enable Device to Device wifi Communication(transferring only a text/string).The code is same as the Apple's sample Witap Application which is downloaded from Developer.Apple.com.

Its working in my network fine and another networks also.

However its not working in my client site.

I spent time at the Client site to sort out the issue with the Devices not communicating to each other and this is what I found. They in their security setup block peer to peer communication…" and my device communication is identified as peer to peer .

Is there any way to solve this problem Is there anything other than PEER 2 PEER wifi communication which apple supports?

Prototype WIFI applications Working Concepts

There are mainly four classes in WiFi application named as AppController, Picker, BrowserViewController, TCP Server.

When application loads the AppController class will initialize NSInputStraem and NSOutPut Stream.

And also it will call “start” method from TcpServer class to set port number.

After it will call “enableBounjourWithDomain” method from TcpServer class.

The above method call with a parameter called as identifier (it is a common name eg:WiTap) and the sender part is searching devices with this common identifier.

After the execution of this method the sender device can identify our device and able to connect.

Getting Own Device Name

Tcp serverServer delegate “DidEnabledBounjer” will work after the above code execution and it will give the current device name.

Then NSNetservice delegate “didFindService” will work (it work when each service discovered) and retrieve the discovered service name.

After getting the new service name we will check either it is same to our device name which we got from “DidEnabledBounjer” delegate.

if not ,the new service name will add into a NSMutable array named as services.

Then services array bind t o the Table view and we can see the list of discovered device names.

discovering the new devices:

No timer settings for discovering the new devices.

When a new device is connected in the same WiFi net work the “DidFindservice” delegate will trigger(it is a NSNetservice delegate implemented in BrowserViewController class).

DidFindservice will give the new device name .After getting it we will check either it is same to our device name witch we got from “DidEnabledBounjer” delegate.

if not ,the service name will add into a NSMutable array named as services.

Then sort all the discovered ;device names according to the Device name and reload the Table View.

Working after selecting a device name from Table View

After clicking device name on the TableView it will call “didSelectRowAtIndexPath” delegate which is implemented in BrowserViewController class( it is a TableView Class delegate) .

It will select a NetService name from our services array(holds all the discovered services) according to the TableView index and set resultant NSService as Current Service.

Trigger a delegate “didResolveInstance” and it will set the InPutStream and OutPutStream values.

After get ting values for InPutStream and OutPutStream it will call “OpenStream” method to open the input and output Streams.

Finally it release the NSService and Picker objects and ready to send messages with selected devices.

Working of send Button

Call “send “ function from BrowserViewController class with a string parameter .It may be user text input or generated string after speech recognition.

Convert the input string as a uint_8 data type and send it to the receiver device.

Receiver Side Working

When a data came to receiver device the “TcpServerAcceptCallBack” delegate will trigger(implemented in TcpServer Class).

It will call “DidAcceptConnectionForServer” method from BrowserViewControll calss through another TcpServer class delegate named “HandleNewConnectionFromAddress”.

Trigger the “stream handle delegate” which is in “AppController “ class and it will check is there any bites available or not.

If bytes are available convert the uint_8 type data to string and we are displaying the resultant string in receiver text box.

And also loading images and displaying it in Image View from AppBundle using the resultant string.< /p>

public class MyGcmListenerService extends GcmListenerService { @Override public void onMessageReceived(String from, Bundle data) { super.onMessageReceived(from, data); Log.i(Constants.LOG_TAG, "Got GCM message " + data.getString("message")); } }

The server uses PushJack and sends to the registration id's. I can see that the server can send the messages, I can get my registration id and register it with our server, but the onMessageReceived never gets called... I also made the google-services.json using the link on the website, so that should also be okay.

Any or all ideas are welcome.

8151662 0 TestNG enabled = false tests not showing as Skipped

We have a number of TestNG tests that are disabled due to functionality not yet being present (enabled = false), but when the test classes are executed the disabled tests do not show up as skipped in the TestNG report. We'd like to know at the time of execution how many tests are disabled (i.e. skipped). At the moment we have to count the occurrences of enabled = false in the test classes which is an overhead.

Is there a different annotation to use or something else we are missing so that our test reports can display the number of disabled tests?

30565155 0

the question is a bit too broad.

you have to step back and look at how source code in general ends up being executed (i.e. it is used).

In case of some programming languages (e.g. C/C++) it's compiled to a native form and can be executed directly afterwards;

In case of other languages it's compiled to an intermediate form (e.g. Java/C#) and executed by a vm (jvm/clr)

In case of yet other languages is interpreted at runtime (e.g. Ruby/Python).

So in the specific case of Ruby, you have the interpreter that loads the rb files and runs them. This can be in the context of standalone apps or in th e context of a web server, but you almost always have the interpreter making sense of the ruby files. you don't get an executable the same way as the you get for languages that are compiled to machine code.

Instead of trying to parse the output of ls, which is bad, you should simply use file system operation provided by node.js. Using file system operations you can be sure your program will work in (almost) any edge case as the output is well defined. It will even work in case the folder will contain more or less files than three in the future!

As you stated in the comments that you want the names and date / time of the files from a folder. So let us have a look at:

fs.readdir(path, callback): fs.readdir will give you an array of filenames in the folder specified in path. You can pass them to fs.stat to find out the mtime:

fs.stat(path, callback): fs.stat() will give you an object of fs.Stats which contains the mtime in the mtime property.

So your code will look something like this afterwards:

fs.readdir('dir', function (err, files) { for (var i = 0; i < files.length; i++) { (function () { var filename = files[i] fs.stat('dir/' + filename, function (err, stats) { console.log(filename + " was last changed on " + stats.mtime); }); })(); } });

The output is:

[timwolla@~/test]node test.js 5 was last changed on Fri Mar 01 2013 20:24:35 GMT+0100 (CET) 4 was last changed on Fri Mar 01 2013 20:24:34 GMT+0100 (CET) 2 was last changed on Fri Mar 01 2013 20:24:33 GMT+0100 (CET)

In case you need a return value use the respective Sync-versions of these methods. These, however, will block your node.js eventing loop.

37072931 0 Getting HTML elements via XPath in bash

I was trying to parse a page (Kaggle Competitions) with xpath on MacOS as described in another SO question:

curl "https://www.kaggle.com/competitions/search?SearchVisibility=AllCompetitions&ShowActive=true&ShowCompleted=true&ShowProspect=true&ShowOpenToAll=true&ShowPrivate=true&ShowLimited=true&DeadlineColumnSort=Descending" -o competitions.html cat competitions.html | xpath '//*[@id="competitions-table"]/tbody/tr[205]/td[1]/div/a/@href'

That's just getting a href of a link in a table.

But instead of returning the value, xpath starts validating .html and returns errors like undefined entity at line 89, column 13, byte 2964.

Since man xpath doesn't exist and xpath --help ends with nothing, I'm stuck. Also, many similar solutions relate to xpath from GNU distributions, not in MacOS.

Is there a correct way of getting HTML elements via XPath in bash?

13031542 0 algorithms to emulate human movement in a stick figure

I need to make a program that lets you animate a stick figure, so I'm looking for some information on algorithms to emulate human movement. I found some software that lets you create animations with stick figures, but are hard to use because basically they don't help you emulate realistic movement, so the animator is responsible for everything. That's cool when you are or have an animator, but I'm not, I'm only a programmer.

I would really appreciate if someone knows about a library, or text with an explanation of these kinds of algorithms.

If you can specify what kinds of search strings this method will accept, you can use regular expressions. Here's an example which also uses Linq for brevity:

public IList<String> GetMatchingRemoteFiles(String SearchPattern, bool ignoreCase) { var options = ignoreCase ? RegexOptions.IgnoreCase : RegexOptions.None; return thirdPartyTool.ftpClient.GetCurrentDirectoryContents() .Where(fn => Regex.Matches(fn, SearchPattern, options)) .ToList(); }

Even if you cannot control what kinds of search strings this method accepts, it's still probably easier to convert the search string to a regular expression than write your own algorithm for matching the patterns. See Bobson's answer for details on how to do this.

So I came up with a different solution. Instead of trying to save an array, I just saved the post ID which would allow me access to the title of the post as well as the permalink.

This is my modified code

<select name="pastor_select"> <?php $args = array( 'post_type' => 'employee', 'position' => 'pastor' ); $pastorList = new WP_Query($args); while ($pastorList->have_posts()) : $pastorList->the_post(); $employeeID = get_the_ID(); // THIS FIXED THE PROBLEM $is_selected = ($employeeID == $selected) ? 'selected="selected"' : ''; echo '<option value="'.$employeeID.'" '.$is_selected.'>'.get_the_title().'</option>'; endwhile; wp_reset_postdata(); ?> </select>

And this is how I am calling it on the front end

<?php $id = $post_meta_data['pastor_select'][0]; echo '<a href="'.get_permalink($id).'">'; echo get_the_title($id); echo '</a>'; ?>

Output on console is:

Tr1: Tr2: H?hentraining

So it seems to me that by saving the domainobject something happens that replaces the Special character "ö" with a questionmark "?". How do I get rid of this problem? Thanks in advanced!

Using Grails 1.3.7

INSERT INTO TRAININGCAMP VALUES('H\ufffdhentraining','Alpen')

No matter I write an "ö" or "ü or "ä" it allways replace it with "\ufffd" So, any suggestions to solve this problem?

__edit2: New insight: The Problem only occur when I save the domain in BootStrap.groovy. By saving the domain in a controller the output on the console is as expected:

Tr2: Höhentraining

The convention for REST is that we use HttpMethods for CRUD operations selection:

GET - Read opeation (list and GetById)
POST - Insertion
PUT - Udpating
DELETE - Deletion

The detailed description: Creating a Web API that Supports CRUD Operations

And then with a very default Routing setting (see more here: Routing in ASP.NET Web API )

routes.MapHttpRoute( name: "API Default", routeTemplate: "api/{controller}/{id}", // the Director as controller defaults: new { id = RouteParameter.Optional } );

So, we've just instructed the Web API infrastructure, that if there is method:

[HttpPost] public void InsertDirector(Director director) ...

It will be used for creation, and the HttpMethod used must be POST and

//[HttpPost] [HttpPut] // !! Attention, here is the difference public void UpdateDirector(Director director)...

the UpdateDirector will be called if the HttpMethod is PUT

NOTE: because during the update we do have the ID of existing product, the Update method should look like:

// the id parameter is a convention as well, // to be sure that we are updating existing item // so this would be better public void UpdateDirector(int id, Director director)...

TCP has no concept of packets. A TCP stream is a continuous stream of bytes - if you want a structure within that stream of bytes, you have to impose it yourself, by implementing some kind of framing mechanism. A simple one is the "length prefix" - when sending an application-level frame, you first send the length of the frame, then the data.

20959054 0 Why is there a dramatic difference between aov and lmer?

I have a mixed model and the data looks like this:

> head(pce.ddply) subject Condition errorType errors 1 j202 G O 0.00000000 2 j202 G P 0.00000000 3 j203 G O 0.08333333 4 j203 G P 0.00000000 5 j205 G O 0.16666667 6 j205 G P 0.00000000

Each subject provides two datapoints for errorType (O or P) and each subject is in either Condition G (N=30) or N (N=33). errorType is a repeated variable and Condition is a between variable. I'm interested in both main effects and the interactions. So, first an anova:

> summary(aov(errors ~ Condition * errorType + Error(subject/(errorType)), data = pce.ddply)) Error: subject Df Sum Sq Mean Sq F value Pr(>F) Condition 1 0.00507 0.005065 2.465 0.122 Residuals 61 0.12534 0.002055 Error: subject:errorType Df Sum Sq Mean Sq F value Pr(>F) errorType 1 0.03199 0.03199 10.52 0.001919 ** Condition:errorType 1 0.04010 0.04010 13.19 0.000579 *** Residuals 61 0.18552 0.00304

Condition is not significant, but errorType is, as well as the interaction.

However, when I use lmer, I get a totally different set of results:

> lmer(errors ~ Condition * errorType + (1 | subject), data = pce.ddply) Linear mixed model fit by REML Formula: errors ~ Condition * errorType + (1 | subject) Data: pce.ddply AIC BIC logLik deviance REMLdev -356.6 -339.6 184.3 -399 -368.6 Random effects: Groups Name Variance Std.Dev. subject (Intercept) 0.000000 0.000000 Residual 0.002548 0.050477 Number of obs: 126, groups: subject, 63 Fixed effects: Estimate Std.

So for lmer, Condition and the interaction are significant, but errorType is not.

Also, the lmer result is exactly the same as a glm result, leading me to believe something is wrong.

Can someone please help me understand why they are so different? I suspect I am using lmer incorrectly (though I've tried many other versions like (errorType | subject) with similar results.

Try calling invalidateLayout on your layout before calling reloadSections:. That will cause the layout to be re-applied after the sections are redrawn, which should cause your footer to redraw.

4769388 0 How to define that float is half of the number?

What would be the most efficient way to say that float value is half of integer for example 0.5, 1.5, 10.5?

First what coming on my mind is:

$is_half = (($number - floor($number)) === 0.5);

Is there any better solutions?

40868428 0 Tree Network in D3 with custom HTML

I am trying to draw a tree like a path in d3 but I haven't been able to make it work. The idea is to have nodes with custom HTML in them. The paths start at the same node and end in the same node. How can I draw this with d3?

This is the desired output

Some nodes repeat themselves in different places. For example D happens after C and it also happens after A. Also C happens after A and after D. The start and end is always the same but everything in between is not.

I tried using treant JS and D3 but so far nothing I have done has worked.

Thanks

40597026 0 regex character appears exactly x times

I'm working in bash and I have a large file in which I want to remove all the lines that do not match a certain regex, probably using $ grep -e "<regex>" <file> > output.txt

What I want to keep is any line that contain exactly x times a specified character, for example in the binary sequence

0000, 0001, 0010, 0011, 0100, 0101, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111

I would like to keep only those who have 2 1, leaving me with

0011, 0101, 0110, 1001, 1010, 1100

I would then use a bash variable to vary the amount I need (always exactly half of the length, working with strings of the same length) I'm litterally looking for lines that are half 0 and half 1

I have this right now. It's not using regex. It works, but is very slow:

($1 is the length of every string, $d is just a directory)

sed -e 's/\(.\)/\1 /g' < $d/input.txt > $d/spaces.txt awk '{c=0;for(i=1;i<=NF;++i){c+=$i};print c}' $d/spaces.txt > $d/sums.txt grep -n "$(($1/2))" $d/sums.txt | cut -f1 -d: > $d/linenums.txt for i in $(cat $d/linenums.txt) do sed "${i}q;d" $d/input.txt done > $d/valids.txt

In case you wonder this puts spaces in between every digit turning 1010 into 1 0 1 0, then it adds the values together, saves the results in sums.txt, grep for length/2 and save only the line numbers in linenums.txt, then it reads linenums.txt and outputs the corresponding line from input.txt to output.txt

I need something quicker, the for loop is what's taking way too long

Thanks for your time and for sharing your knowledge with me.

zerkms's answer cuts to the gist of what you actually need to know, and is correct. Transaction isolation will make sure you're not affected by concurrency issues in this simple case (but note, it's not a magic solution to all concurrency).

To answer your question literally as written: they're actually interleaved.

If you write:

SELECT SUM(field1)+SUM(field2)+SUM(field3)-SUM(field4) FROM mytable;

then Pg reads mytable once. It reads each row and feeds the mytable.field1 to the first sum, mytable.field2 into the second sum, etc. Then it repeats for each row.

So all the aggregation is done in parallel (though not using multiple CPUs).

My way of doing this is simple:

When a user loads a page, their "last page load time" is updated in the database.
A cron script runs every minute. It looks for users whose "last page load time" was in the last minute.
Increment the "time spent on site" for each user found.

In this way, I can keep track of users accurately to the minute. Just divide by 60 to get the hours.

Add 3 to your allocation amount. Allocate the memory. If the returned address isn't already a multiple of 4, round it up until it is. (The most you'd have to round up is 3, which is why you pad your allocation by that much in advance.)

When you free the memory, remember to free the original address, not the rounded-up value.

The way you are storing data breaks normalization rules. Only a single atomic value should be stored in each field. You should store each item in a single row.

From the error log i.e. MediaPlayer Event 11 was not found in the queue, already cancelled is a warning and not an error. Please refer to this link. Hence, if your MediaPlayer is exiting, then there should be some other issue.

This warning is printed when an event which was expected to be triggered gets removed from the queue before it actually triggered. This can happen in multiple cases. For example, in case of pause, all player events are cancelled as shown here.

In your case, I feel that one of the potential scenario would be thus. AwesomePlayer would have triggered an event to read the next video frame from the video decoder i.e. mVideoSource. In between you pressed pause which caused all events to be removed. So when TimedEventQueue triggered in this threadRun loop, it would observe that this event has been removed and hence, the log.

That’s a runtime exception so the compiler can’t help you with catching it at a compile time. And the try-catch block helps you to handle this exception, not to prevent it from being thrown at the runtime. If you don’t make a try-catch block it will be handled at a general application level.

A quote from MSDN:

When an exception is thrown, the common language runtime (CLR) looks for the catch statement that handles this exception. If the currently executing method does not contain such a catch block, the CLR looks at the method that called the current method, and so on up the call stack. If no catch block is found, then the CLR displays an unhandled exception message to the user and stops execution of the program.

Please refer to the MSDN try-catch for more information.

I'm not sure php is the right tool here. Why not use something that is closer to the shell environment, like a bash script?

The only reason I can imagine you want to use PHP is so you can start the process by clicking a link on a page somewhere, and thereby punch a large hole in whatever security your system supposedly has. But if you really must, then it is still easier to write a script in a more shell friendly language and simply use php as a gateway to invoke the script.

This will work in quirks mode, but the browser which is compatible with standard mode will not work depend upon your doctype. Avoiding quirks mode is one of the keys to successfully producing cross-browser compatible web content

Some modern browsers have two rendering modes. Quirk mode renders an HTML document like older browsers used to do it, e.g. Netscape 4, Internet Explorer 4 and 5. Standard mode renders a page according to W3C recommendations. Depending on the document type declaration present in the HTML document, the browser will switch into either quirk mode or standard mode. If there is no document type declaration present, the browser will switch into quirk mode.

I'm new with WTForms but it seems to me that the solution could be improved instead of using :

{{ form.field(autofocus=true, required=true, placeholder="foo") }}

use :

{% if field.flags.required %} {{ field(autofocus=true, required=field.flags.required, placeholder="foo") }} {% else %} {{ field(autofocus=true, placeholder="foo") }} {% endif %}

WTForms seems not to handle correctly required=false for 100% HTML5 and sets in the HTML an attr required="False" instead of removing the attr. Could this be improved in next version of WTForms?

36443204 0 Using auto layout at the expense of having no frame

I have a box that is initiated without a frame so it has 0 center and size.

Is there anyway to insert a centered subview into the blackBox without using autolayout or is there a neater way I could/should use it. The only way I can see this happening is:

Obviously, it has common field of the table Meetings and Tags so that I can add record on it by this way

var tag= new Tag() { Title = "Meeting Title", }; meeting.Tags.Add(tag);

Looks good, however I'm getting this error in Context.SaveChanges() when Inserting new Tags record.

Unable to update the EntitySet 'MeetingTags' because it has a DefiningQuery and no <InsertFunction> element exists in the <ModificationFunctionMapping> element to support the current operation

Tags has Primary Key.

I think putting a Primary Key in the MeetingTags is not possible as it will break the Many-to-Many relationship of Meeting and Tags in the EF, and it will also add Meeting.MeetingTags.Tags in the syntax instead of just Meeting.Tags

Any workaround on this?

There is no significant difference between these, you will get pretty much the same results:

 str.Split(';').First() vs. str.Split(';')[0]

For your second comparison, here you are asking only the first element

list.Where(x => x > 1).First()

So as soon as WhereIterator returns an item it's done. But in second you are putting all results into list then getting the first item using indexer , therefore it will be slower.

Calculating your angle using just x value seem strange, try this:

angle = Math.atan( (startY - endY) / (startX - endX) ); // in rad

This will give you the angle in radian.

For calculating the velocity you must have a timing variable between the start and the end touch. You can use getTimer() to get beginTime and endTime in your functions onTouchBegin and onTouchEnd respectively.

After that you just have to calculate velocity with distance and time.

distance = Math.sqrt( ((startX - endX)*(startX - endX)) / ((startY - endY)*(startY - endY)) ); velocity = distance / (endTime-beginTime); // in pixel/ms

Hope that helps ;)

You could do something like this:

The following unit test succeeds:

[TestMethod] public void Test5() { MyString myString = new MyString(); string s = myString; Assert.AreEqual("ploeh", s); }

In general however, I don't think this is a sign of good API design, because I prefer explicitness instead of surprises... but then again, I don't know the context of the question...

I agree with JDillon's answer to set the data-src and then switch the src when ready to init the player. Like so:

html

<iframe id="sc-widget" width="0" height="0" scrolling="no" frameborder="no" src="" data-src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/3333333%3Fsecret_token%3Dx-xxxx&amp;auto_play=false&amp;hide_related=false&amp;show_comments=true&amp;show_user=true&amp;show_reposts=false&amp;visual=true"></iframe>

js (es6)

let widgetIframe = document.getElementById('sc-widget') widgetIframe.src = widgetIframe.dataset.src let $embedPlayer = SC.Widget(widgetIframe) /* example of using soundcloud embed player */ $embedPlayer.bind(SC.Widget.Events.PLAY, () => { $embedPlayer.getDuration((duration) => setDuration(duration)) }) $embedPlayer.bind(SC.Widget.Events.PLAY_PROGRESS, () => { $embedPlayer.getPosition((position) => setPosition(position)) }) function setPosition(pos) { console.log(pos) } function setDuration(dur) { console.log(dur) }

Then I also agree with adi's answer that you cannot use display: none; to hide the player if you are creating your own player to control the soundcloud embed player. In this case you need to hide it with the following styles:

css

iframe { max-width: 10rem; opacity: 0; position: absolute; visibility: hidden; }

You have some bugs in your getMessages function in the while loop:
1. use count += len(rs)
2. The major bug: you don't need the

or len(rs) < 10

condition because SQS can get up to 10 messages and if your queue is full and each time you get 10 messages you'll have an infinite loop.

Also I think you should consider using yield statement to return the messages, process them and after they are processed, only then , remove them from Queue.

One more thing, the pythonic way to check if len(rs) < 1: is if not rs:

#include <qsplashscreen.h> #include "linkcontrol.h" #include "configure.h" #include <unistd.h> #include <QApplication> #include <QPixmap> #include <QStyle> #include <QDesktopWidget> #include "linkports.h" #include "joystickthread.h" #include <X11/Xlib.h> int main(int argc, char *argv[]) { XInitThreads(); QApplication a(argc, argv); QPixmap pix(":splash.png"); QSplashScreen splash(pix); splash.show(); a.processEvents(); JoystickThread jsThread; jsThread.start(); LinkControl linkcontrol; usleep(1000000); splash.finish(&linkcontrol); usleep(100000); linkcontrol.show(); linkcontrol.setGeometry(QStyle::alignedRect(Qt::LeftToRight, Qt::AlignCenter,linkcontrol.size(),a.desktop()->availableGeometry())); return a.exec(); }

The actual thread is in joystickthread.cpp

#include "joystickthread.h" #include "global.h" #include "unistd.h" /* JoystickThread::JoystickThread(int _interval) { this->interval_us = _interval; } */ void JoystickThread::run() { while(1) { if(joystick->connected) { joystick->updateJSData(); // Check for changed values for(int i=0; i<joystick->axis.count(); i++) { if(joystick->axis.value(i) != joystick->axis_last[i]) { joystick->axisUpdateEmit(i); // qDebug() << "AXIS: " << i << "\tVALUE: " << joystick->axis.value(i); } joystick->axis_last[i] = joystick->axis.value(i); } for(int i=0; i<joystick->button.count(); i++) { if(joystick->button.value(i) != joystick->button_last[i]) { joystick->btnUpdateEmit(i); // qDebug() << "BUTTON: " << i << "\tVALUE: " << joystick->button.value(i); } joystick->button_last[i] = joystick->button.value(i); } } usleep(2500); } }

The function that causes the program to crash is in linkcontrol.cpp

void LinkControl::on_actionJoystick_Test_triggered() { qDebug() << "STARTING CHECK"; if(!js_test->initialized) { qDebug() << "NOT INIT"; js_test = new TestJoystick(); js_test->initialized = true; qDebug() << "FININSH INIT"; } if(joystick->connected) { qDebug() << "SHOWING UI"; js_test->show(); } else { QMessageBox::critical(this, tr("No Joystick Connected!"), tr("Please connect a joystick first...")); } }

Where js_test is declared as a TestJoystick object in the linkcontrol.h file

public: explicit LinkControl(QWidget *parent = 0); QSlider *portSliders[16]; QLineEdit *setVals[16]; SerialTerminal *ser_term; TestJoystick *js_test; ~LinkControl();

18603273 0 NodeJS Code Coverage of Automated Tests

As part of a custom testing framework for a NodeJS REST API, I'd like to automatically detect when my tests are no longer providing proper coverage by comparing all possible outcomes with what the test suite received.

What methods exist for doing this? We can assume that it's being used for a REST API with a list of entry functions (API endpoints) that need coverage analysis, and each entry function will end with a known 'exit function' that responds to the requester in a standard way.

Here's what I've found so far:

1: Basic solution (Currently implemented)

When writing each REST endpoint, manually create a list of all the possible outcome 'codes' [Success, FailureDueToX, FailureDueToY] for example
After the tests have run, ensure every code in the list has been seen by the test suite for each endpoint.

Pros: Very basic and easy to use; Doesn't change performance testing times

Cons: Highly prone to error with lots of manual checking; Doesn't flag any issues if there are 5 ways to 'FailDueToX' and you only test 1 of them. Very basic definition of 'coverage'

2: Static analysis

Parse the code into some sort of parse tree and look for all the instances of the 'exit function'
Traverse up the tree until an API Endpoint is reached, and add that exit instance to the endpoint as an expected output (needs to keep a record of the stack trace to get there via a hash or similar)
When tests are run, the endpoints return the stack trace hash or similar and this is compared to the expected output list.

Pros: Automatic; Catches the different branches that may result in the same output code

Cons: Generating the parse tree is non trivial; Doesn't detect dead code that never gets run; test suite needs to be kept in sync

3: Profiling

I've done this in the past on Embedded Systems with GreenHills Code Coverage Tools

Start up a profiler like dtrace and record the stack log for each test separately
Parse the stack log and assign the 'test' to each line of code
Manually analyse the code-with-annotations to find gaps.

Pros: Semi Automatic; Gives more information about total coverage to a developer; Can see

Cons: Slows down the tests; Unable to do performance testing in parallel; Doesn't flag when a possible outcome is never made to happen.

What else is there, and what tools can help me with my Static Analysis and Profiling goals?

Using java 8 shouldn't give this problem but it did for me

I created my jar initially from Eclipse Export -> Runnable Jar and it was fine. When I moved to Maven it failed with the above.

Comparing the two jars showed that nothing fx related was packaged with the jar (as I'd expect) but that the Eclipse generated manifest had Class-Path: . in it. Getting maven to package the jar with the following worked for me (with Java 8)

 <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <configuration> <archive> <manifest> <addClasspath>true</addClasspath> <mainClass>com.pg.fxapplication.Main</mainClass> </manifest> <manifestEntries> <Class-Path>.</Class-Path> </manifestEntries> </archive> </configuration> </plugin> </plugins> </build>

Apple doesn't offer support for that, but one workaround could be to use a category for UIImage with a method that loads the right version based on the OS version:

+(UIImage)imageNamed2:(NSString *)imageName{ NSString *finalImageName; if([[UIDevice currentDevice].systemVersion floatValue] >= 7){ finalImageName = [NSString stringWithFormat:@"ios7-%@",imageName]; }else{ finalImageName = imageName; } return [self imageNamed:finalImageName]; }

This way, the images would be named:

example.png example@2x.png ios7-example@2x.png

And you can instantiate the image this way:

[UIImage imageNamed2:@"example.png"];

Hope this helps

route seems to be matched but i get missing table error, i have set up SymfonyDoctrineContext to take care of schema creation.

Seems that all of You misunderstood my question and/or completely ignored my first sentence.

I have a working application and I access it using

http://web.dev/web/ (http://web.dev/web/app.php/) <-- for prod

http://web.dev/web/app_dev.php/ <-- for dev

http://web.dev/web/app_behat.php/ <-- for behat

all of them work as when i use them manually in chrome or other browser

That is why I am surprised why http://web.dev/web/app_behat.php/ gives me

No route found for "GET /web/app_behat.php/login"

and

http://web.dev/app_behat.php/ gives

With little debugging I confirmed SymfonyDoctrineContext does read my entities mappings and issues queries to create db schema, both db files have read/write permissions (for sake of test I gave them 777)

Another thing I just realised, all this errors gets written to test.log file instead of behat.log. I create kernel with $kernel = new AppKernel('behat', true);

Maybe I just greatly misunderstood how behat is supposed to work?

EDIT2:

I have noticed that there are no entries made to apache access log when running behat feature for either of the paths

Further to Gabe's answer, I can confirm that the difference appears to be caused by the cost of re-constructing the delegate for every call to GetPointData.

If I add a single line to the GetPointData method in your IterationRangeLookupSingle class then it slows right down to the same crawling pace as LinqRangeLookupSingle. Try it:

// in IterationRangeLookupSingle<TItem, TKey> public TItem GetPointData(DateTime point) { // just a single line, this delegate is never used Func<TItem, bool> dummy = i => i.IsWithinRange(point); // the rest of the method remains exactly the same as before // ... }

(I'm not sure why the compiler and/or jitter can't just ignore the superfluous delegate that I added above. Obviously, the delegate is necessary in your LinqRangeLookupSingle class.)

One possible workaround is to compose the predicate in LinqRangeLookupSingle so that point is passed to it as an argument. This means that the delegate only needs to be constructed once, not every time the GetPointData method is called. For example, the following change will speed up the LINQ version so that it's pretty much comparable with the foreach version:

// in LinqRangeLookupSingle<TItem, TKey> public TItem GetPointData(DateTime point) { Func<DateTime, Func<TItem, bool>> builder = x => y => y.IsWithinRange(x); Func<TItem, bool> predicate = builder(point); return this.items.FirstOrDefault(predicate); }

40384521 0 R: replace values in a vector before and after a condition is met

Consider a vector with missing values:

myvec <- c('C', NA, 'test', NA, 'D') [1] "C" NA "test" NA "D"

How to replace all the elements in the vector before 'test' with, say, 'good' and after it with 'bad'? The outcome should be:

[1] "good" "good" "test" "bad" "bad"

My attempt below succeeds only in replacing everything with 'good', which is not so good:

replace(myvec, is.na(myvec) | myvec!='test', 'good') [1] "good" "good" "test" "good" "good"

34526156 0 HTML5 Notification With PHP

I noticed Facebook started using the HTML5 notification for desktop and I thought I would start dabbling in it for fun for my blog. My idea is pretty simple: new blog comes out, apache cronjob runs every X minutes and calls a file, does some PHP wizardry and out goes the notification.

I have looked online and found examples using node.js and angular, but I'm not comfortable using either of those so I'd rather stick with PHP.

Here is my process: The user goes to my blog and will click a button to allow notifications. For brevity, the below code sends the users a notification when they click the "notify" button. This works perfectly, and in theory should subscribe them to any future notifications.

if ('Notification' in window) { function notifyUser() { var title = 'example title'; var options = { body: 'example body', icon: 'example icon' }; if (Notification.permission === "granted") { var notification = new Notification(title, options); } else if (Notification.permission !== 'denied') { Notification.requestPermission(function (permission) { if (permission === "granted") { var notification = new Notification(title, options); } }); } } $('#notify').click(function() { notifyUser(); return false; }); } else { //not happening }

You can see the fiddle of the above.

Access to the user is granted and now I should be able to send them notifications whenever I want. Awesome! I then write up a blog entry and it has the ID of XYZ. My cronjob goes and calls the following PHP script, using the above node.js example as a template.

(In this example I am just calling the script manually from my phone and watching my desktop screen. Since my desktop is "subscribed" to the same domain, I think the following would/should work.)

$num = $_GET['num']; $db = mysql_connect(DB_HOST, DB_USER, DB_PASS); if($db) { mysql_select_db('mydb', $db); $select = "SELECT alert FROM blog WHERE id = ".$num." && alert = 0 LIMIT 1"; $results = mysql_query($select) or die(mysql_error()); $output = ''; while($row = mysql_fetch_object($results)) { $output .= "<script> var title = 'new blog!'; var options = { body: 'come read my new blog!', icon: 'same icon as before or maybe a new one!' }; var notification = new Notification(title, options); </script>"; $update = "UPDATE blog SET alert = 1 WHERE id = ".$num." && alert = 0 LIMIT 1"; mysql_query($update) or die(mysql_error()); } echo $output; }

I then check the database and blog entry XYZ's "alert" is now set to "1", yet my desktop browser never got notified. Since my browser is subscribed to the same URL that is pushing out the notification, I would imagine I'd get a message.

Either I'm doing something wrong (perhaps PHP isn't the right language for this?), or I'm misunderstanding the spec. Could somebody help point me in the right direction? I think I'm missing something.

Thanks a lot.

Update 1

According to the comments, if I just call a script with this in it:

 var title = 'new blog!'; var options = { body: 'come read my new blog!', icon: 'same icon as before or maybe a new one!' }; var notification = new Notification(title, options);

It should hit all devices that are subscribed to my notifications. I tried this on my phone but my desktop still didn't get a notification. I still think I'm missing something as my notifications seem stuck to one device and can only be called on page-load or on click as opposed to Facebook which sends you notifications even if the page isn't open in your browser.

The literal-object syntax cannot be used for non-literal keys. To use a non-literal key with an object requires the object[keyExpression] notation, as below. (This is equivalent to object.key when keyExpression = "key", but note the former case takes an expression as the key and the latter an identifier.)

var output = [] $('.grab').each(function(index) { var obj = {} obj[$(this).attr('name')] = $(this).val() output.push(obj) })

Happy coding.

Also, consider using .map():

var output = $('.grab').map(function() { var obj = {} obj[$(this).attr('name')] = $(this).val() return obj })

20211228 0 Android SDK (Eclipse) : How to create a simple timer for a simple App?

i have a simple Application about writing the sentence which is shown when the application starts.The only Problem is, i need the application to calculate the time it took the user to write the sentence .. like when you touch "Submit" Button , the Toast message will say " Thats Right ! , It took you 3.2 Second" As Example .

I heard you can set a timer to start on when specific action occurs ... and you can order it to stop .

So let's say The Timer will start when you start the app and it will stop when you touch "Submit" button , and give a toast message like above calculating the exact time it took you to write the sentience after starting the App ! *

Here is the App Code hope it helps : *

Button w; TextView t; EditText e; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); w = (Button) findViewById(R.id.Write); t= (TextView) findViewById(R.id.FTS); e = (EditText) findViewById(R.id.Text); w.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String check1 = t.getText().toString(); String check2 = e.getText().toString(); if (check1.equals(check2)) Toast.makeText(MainActivity.this,"You Wrote it Right !!!",Toast.LENGTH_LONG).show(); else if (check2.equals("")) Toast.makeText(MainActivity.this,"It's Empty",Toast.LENGTH_LONG).show(); else Toast.makeText(MainActivity.this,"You wrote it wrong,try again !",Toast.LENGTH_LONG);

I'm Totally new to Android so I really don't know how to do it , Thanks for your Time .*

You could have your Line object implement the Comparable interface. You could then put the comparison logic within the Line class in the compareTo method. The logic there will test whether the slope and the intercept match, and if so return 0. Other results could return 1 or -1 to enforce ordering, if you want.

Obviously, you don't need to implement this interface to effect your desired results. However, as this is homework, doing so will allow you to play around with some features of the JDK, like using sorted Lists, etc. With a sorted list, for example, you could obviate the need for a nested loop, as you would only need to compare the object in question against one you just removed from the Iterator in the previous iteration to see if you need to add it to an existing linelist or start a new one.

Generally, nowadays you shouldn't ever need to manually add /// <reference... references. If you've got your type definitions installed using NPM then they should be automatically included in your compilation process.

All you need to do is import the module and start using it. For example, in a new empty test project I've just installed xlsx (npm install xlsx @types/xlsx) and I can now successfully compile and run the below:

import xlsx = require("xlsx"); var workbook = xlsx.readFile("test.xlsx");

That should be all you need.

In fact it's not cut off at the top, it just has a space at the bottom, which is rendered by the inline img. If your div contains only the image, you can just set font-size:0 for your div. Also you can set the border for your img instead:

.details-big { border-top: 8px solid #f0f0f0; border-bottom: 8px solid #f0f0f0; font-size:0; }

You can also set display:block for your img:

.details-big > img { display:block; }

I have to use this web service method that takes three parameters, a string and two xml params.

Below's an example of the code I'm using. The web service method throws an exception, 'Required parameters for method SubmitXml are null.'

So I'm guessing it's not receiving any xml on the 2nd and 3rd params. Can anyone give me a hint on how to correctly use the DOM or any other with PHP here? thank you in advance.

 $soapClient = new SoapClient($this-SOAPURL, array('login'=>$this->account,'password'=>$this->password)); $xmlstr ='<xmlbody>'; $xmlstr.='<someXML>Some XML text content here!</someXML>'; $xmlstr.='</xmlbody>'; $dom = new DOMDocument(); $dom->loadXML($xmlstr); $filter = new DOMDocument(); $filter->loadXML('<_ xmlns=""/>'); print_r ($soapClient->SubmitXml('userIDString',$dom->saveXML(), $fil->saveXML()));

30967702 0 Send UDP data from Windows Service to browser running webpage on same machine

Let's say I have the following code running on a Windows service. I have to send data from a Windows service on a machine to a webpage that is open on the same machine(but not hosted on that machine).

 static void Main(string[] args) { Int32 counter = 0; while (counter < 100) { SendUDP("127.0.0.1", 49320, counter.ToString(), counter.ToString().Length); Thread.Sleep(2000); counter++; } } public static void SendUDP(string hostNameOrAddress, int destinationPort, string data, int count) { IPAddress destination = Dns.GetHostAddresses(hostNameOrAddress)[0]; IPEndPoint endPoint = new IPEndPoint(destination, destinationPort); byte[] buffer = Encoding.ASCII.GetBytes(data); Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); for (int i = 0; i < count; i++) { socket.SendTo(buffer, endPoint); } socket.Close(); System.Console.WriteLine("Sent: " + data); }

I have to listen for the data sent to port 49320 and then process it in the browser.

I can create a listener on the webpage with Node.js like below, but I have to start this service separately and also install node.js on the client.

Is there any alternative to this? Something more lightweight ?

I could also create an AJAX to query a webservice every 2 seconds that would do the same thing as Windows Service, but it seems like a lot of queries sent all the time for nothing.

//websocket gateway on 8070 var app = require('http').createServer(handler) , io = require('socket.io').listen(app) , fs = require('fs'); var mysocket = 0; app.listen(8070); function handler (req, res) { fs.readFile(__dirname + '/index.html', function (err, data) { if (err) { res.writeHead(500); return res.end('Error loading index.html'); } res.writeHead(200); res.end(data); }); } io.sockets.on('connection', function (socket) { console.log('index.html connected'); mysocket = socket; }); //udp server on 49320 var dgram = require("dgram"); var server = dgram.createSocket("udp4"); server.on("message", function (msg, rinfo) { console.log("msg: " + msg); if (mysocket != 0) { mysocket.emit('field', "" + msg); mysocket.broadcast.emit('field', "" + msg); } }); server.on("listening", function () { var address = server.address(); console.log("udp server listening " + address.address + ":" + address.port); }); server.bind(49320);

change the option, then re-initialize:

If you are inserting your rows one at a time I'd recommend changing to a multi-row insert statement if possible as in "insert into events (eventId,content) values (1,'value 1'), (2,'value 2'), ..." as there can be quite a bit of overhead transactions. Also, TokuDB has improved performance with each release, I'd recommend running on a current release.

You can effectively name ranges using the text box in the top left of the screen (where appears the "B2" or whatever coordinate the cell has). Select entire column and insert the name there.

Then the name is valid to use in formulas.

It is not possible to remove anonymous lambdas event handlers. Instead put your lambda into a normal method. Than you can call proxy.GetBasicEntryCompleted -= MyMethod;.

Here is an example how it could look like:

private void OnBasicEntryCompleted(object sender, BasicEntryEventArgs e) { if (e.Result.Any()) { e.TargetComboBox.ItemsSource = e.Result.ToList(); e.TargetComboBox.DisplayMemberPath = "Description"; e.TargetComboBox.SelectedItem = "ID"; } else { e.TargetComboBox.ItemsSource = null; } var proxy = (Proxy)sender; proxy.GetBasicEntryCompleted -= OnBasicEntryCompleted; } public void Sniper(string sourceTableName, ComboBox targetComboBox) { proxy.GetBasicEntryCompleted += OnBasicEntryCompleted; proxy.GetBasicEntryAsync(sourceTableName, targetComboBox); }

Also be aware that you always subscribe to an event BEFORE you invoke the method that will raise it. Otherwise it could happen, that won't be informed due to a racing condition.

And if you call this async method the question would be in which thread will the completed event be raised? If it happens in thread where the async task had run, you won't be within the gui thread and manipulating gui objects (like the combo box) is not recommended within other threads. So maybe encapsulate your accesses to the combo box within a e.TargetComboBox.Invoke() call.

13713916 0 Am I using default arguments incorrectly?

I've just started going through a beginners book of C++. I have some java experience (but having said that, I've never used default arguments in java to be honest)

So, as mentioned, my issue is with default arguments..

This is the code snippet I'm using:

#include <iostream> using namespace std; //add declaration int add(int a, int b); int main (void) { int number1; cout << "Enter the first value to be summed: "; cin >> number1; cout << "\nThe sum is: " << add(number1) << endl; } int add(int a=10, int b=5) { return a+b; }

The response I get from g++ compiler is: "too few arguments to function 'int add(int, int)'

Am I doing this wrong? (I've also tried it with literal arguments)

P.S. I can't seem to get the code snippet to display properly? Has the system changed?

As far as I know this is currently only supported for fields of a class or top level fields but not for local variables inside a method/function when reflecting at runtime. Maybe source mirrors has more capabilities (I haven't used it yet) but I think this can only be used at compile time.

you can use alien if you want and that's the recommended way to do it actually, but you can install it with rpm too. just install rpm:sudo apt-get install rpm then run sudo rpm -i package_name

Since your scheduled task is actually changing the permissions on the error log file, the only viable options I can see are:

1) Make the scheduled task not write to the error_log. Add the following to the top of the cron job:

error_reporting(E_NONE);

2) Make the scheduled task write to the system log (event viewer in windows) by issuing the following command at the start of your scheduled task (PHP file):

ini_set('error_log', 'syslog');

3) If all of the above do not suit you, you can try scheduling the task as the IIS User/Group. This would insure that the permissions are met and error 500 is no longer caused.

There is no magic fix to this, you can either change the scheduled task so it has the same UID/GID as the PHP process, or you can stop logging in the scheduled_task.

Dollar - $(MyProp): Allows you to reference values specified within PropertyGroups.

At Sign - @(CodeFile): Allows you to reference lists of items specified within ItemGroups.

Percent - %(CodeFile.BatchNum): Allows you to reference batched ItemGroup values using metadata. This is a bit more complicated, so definitely review the documentation for more info.

Take a look at each link for more detailed info on how these are used. Good luck -- hope this helps!

38135976 0 How to call custom back-end methods (parsing objects) using Typescript and Angular resources

I've been struggling for weeks now to get custom service calls to work using Typescript / Angular / C#. I can't seem to find any viable solution online, and the more I look the more I get confused.

My current solution has been structured based mostly on Pluralsight courses. I'm understanding the general connectivity from HTML => Angular (controllers/ models / services), but struggling with the Angular services => C# API controller connection.

Current structure:

app.ts

module App { var main = angular.module("Scheduler", ["ngRoute", "App.Services"]); main.config(routeConfig); routeConfig.$inject = ["$routeProvider"]; function routeConfig($routeProvider: ng.route.IRouteProvider): void { $routeProvider .when("/schedule", { templateUrl: "/app/scheduler/views/scheduler.html", controller: "ScheduleCtrl as sch" }) .otherwise("/schedule"); } }

services.ts

module App.Services { angular.module("App.Services", ["ngResource"]); }

controller.ts

module App.Scheduler { export interface IScheduleParams extends ng.route.IRouteParamsService { scheduleId: number; } export class ScheduleCtrl implements IScheduleModel { scheduleResource: ng.resource.IResourceClass<App.Services.IScheduleResource>; static $inject = ["$routeParams", "scheduleService", "$scope"]; constructor(private $routeParams: IScheduleParams, private scheduleService: App.Services.SchedulerService, public schedule: Schedule) { this.scheduleResource = scheduleService.getScheduleResource(); this.schedule = new Schedule(0, 0, new Array<PaymentEntry>(), 0, new Array <ScheduleEntry>()); } generateSchedule(): void { //todo: Need to call the backend service here to generate entries var returnedSchedules = this.scheduleService.generateSchedules(this.schedule); } }

schedulerService.ts

module App.Services { //INTERFACES //services export interface ISchedulerService { getScheduleResource(): ng.resource.IResourceClass<IScheduleResource>; generateSchedules(schedule: App.Scheduler.Schedule): App.Scheduler.ScheduleEntry[]; //custom service call } //resources export interface IScheduleResource extends ng.resource.IResource<App.Scheduler.ISchedule> { } //CLASSES //Schedule Service export class SchedulerService implements ISchedulerService { static $inject = ["$resource"]; constructor(private $resource: ng.resource.IResourceService) { } //Read operations (single / list) -- this works fine getScheduleResource(): ng.resource.IResourceClass<IScheduleResource> { return this.$resource("api/scheduler/GetSchedules/:scheduleId"); } //custom operations -- **!! NEED HELP HERE PLEASE !!** generateSchedules(schedule: App.Scheduler.Schedule): App.Scheduler.ScheduleEntry[] { return this.$resource("api/schedule/GenerateSchedules/:schedule"); //I need to be able to pass in a Schedule object and receive an array of objects back } } angular .module("Scheduler") .service("schedulerService", SchedulerService); }

models.ts

module App.Scheduler { //INTERFACES export interface ISchedule { param1: number; payments: Array<IPaymentEntry>; schedules?: Array<IScheduleEntry>; } export interface IPaymentEntry { param1: number; param2: number; } export interface IScheduleEntry { param1: number; param2: string; param3: number; } //CLASSES export class Schedule { constructor(public param1?: number, public payments?: Array<IPaymentEntry>, public schedules?: Array<IScheduleEntry>) { } } export class PaymentEntry implements IPaymentEntry { constructor(public param1?: number, public param2?: number) { } } export class ScheduleEntry implements IScheduleEntry { constructor(public param1: number, public param2: string, public param3: number) { } } }

ApiController.CS

public class SchedulerController : ApiController { public IEnumerable<Schedule> GetSchedules() { //... } public Schedule GetSchedules(int id) { //... } [HttpPost] public IEnumerable<PaymentEntry> GenerateSchedules([FromBody]Schedule schedule) { //todo: add random logic here return new Schedule(); }

Any guidance or a working example of how to successfully call the generateSchedules method from the schedulerService.ts to the ApiController.CS would be greatly appreciated to and from the API controller would be greatly appreciated.

9802788 0 Call a REST API in PHP

Our client had given me a REST API to which I need to make a PHP call to. But as a matter of fact the documentation given with the API is very limited, so I don't really know how to call the service.

I've tried to Google it, but the only thing that came up was an already expired Yahoo! tutorial on how to call the service. Not mentioning the headers or anything in depth information.

Is there any decent information around how to call a REST API, or some documentation about it? Because even on W3schools, they only describes the SOAP method. What are different options for making rest API in PHP?

Firstly I'm planning to set up an vehicle tracking system. I have my own server. There is a device which can send the data via GPRS. I can define an IP and a port number to this device. I want to connect this device to my server without and auxiliary device. What I want to ask is which format the device send the data(XML, TXT, or something like that), how I can write the data to the database. And if I have to use a computer to get the coordinates from the device, which language should I use?

32878450 0 node.js - infinite loop during JSONStream

I've got a node.js server that is freezing in production, and it appears to be caused by an infinite loop inside of JSONStream. Here's a stack trace captured from a core dump from a frozen server:

How can I find the source of this infinite loop?

Unfortunately the servers are running in production and are processing many thousands of requests, so it's difficult to give any additional context. The basic function of the servers is to make outbound HTTP requests for other services.

It's worth noting that I don't believe this is caused by a memory leak. The server's memory usage remains constant (and low) during these freeze events, while the CPU spikes to 99%

Another piece of evidence towards the conclusion of an infinite loop is that the event loop itself seems to have stopped. When I put a console.log inside of a setInterval, the server will stop outputting as soon as it freezes.

We have verified that the problem is not caused by expired/corrupted socket connections, by setting the number of max connections to Infinity (which disables their reuse in node.js)

We're using JSONStream 0.7.1 (which includes a default jsonparse version of 0.0.5). We found this issue on the JSONStream repo, and tried forking JSONParse and only updating to the newest jsonparse version. It did NOT fix the issue.

IMHO there are three reasonable scenarios for Optional:

Do something if there is a value
Provide a default value otherwise
The absence of a value is an error condition, in which case you want to fail fast

Your scenario falls into the last category so I would simply write:

 MyDao oq = myOptional.orElseThrow(() -> new RuntimeException("Entity was not found"); if(!oq.getReferenceId().equals(objToUpdate.getId())) throw new RuntimeException("Bad Move!"); oq.setAttribute(objToUpdate.getAttribute());

Of course, it's appealing to use methods like ifPresent, filter or map, but in your case, why would you want to continue when the application is in a faulty state. Now if you wouldn't throw an exception if the entity wasn't found, then the situation would be different.

Something like oq.checkMove(objToUpdate.getId()) could make sense. That would eliminate the if and make the code more expressive.

39999814 0 Why doesn't my Swift 3.0 decoder decodeInteger work for integers?

So we've been using Groups for saving and retrieving some data across an extension and the main app and everything worked fine for Swift 2.3 but then we updated to Swift 3.0 and got some issues.

The current implementation that gives us issues is like following:

open class SomeClass: NSObject, NSCoding { open var someVar: Int! open func encode(with aCoder: NSCoder) { aCoder.encode(self.someVar, forKey:"someVar") } public required convenience init?(coder decoder: NSCoder) { // this is where it breaks self.someVar = decoder.decodeInteger(forKey: "someVar") } }

The following error is thrown:

*** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: '*** -[NSKeyedUnarchiver decodeInt32ForKey:]: value for key (someVar) is not an integer number'

The funny thing is the old implementation for Swift 2.3 works without any issues: self.someVar = decoder.decodeObject(forKey: "someVar") as! Int (I've understood from other posts that this would not work...)

So what could I be doing wrong? It should be said that the original value is retrieved from a float and cast to an int.

I haven't been able to reproduce the behavior you describe in a similar application that I have. The only difference is that I'm not loading the byte array into a MemoryStream first, but just passing the byte array to File.

So try removing the MemoryStream from the equation. So the code would end up something like:

public ActionResult DetailsExcel(string id) { byte[] stream; // changed to byte array using (var excelPackage = new ExcelPackage()) { var ws = excelPackage.Workbook.Worksheets.Add(fileName); ws.Cells["A1"].LoadFromText(csv, this._excelTextFormat); stream = excelPackage.GetAsByteArray(); // removed MemoryStream } return File(stream, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", fileName + ".xlsx"); }

You never place any content in your StringBuffer buffer, so it is empty when you write it to file:

bw.write(buffer.toString());

buffer could potentially consume a large amount of memory here.

A better approach to writing the data to file would be to write the data as you read it from the database:

while (rs.next()) { sampleIddisp = rs.getString(1); ... bw.write(....); }

18632968 0 MQTT Android not connecting to ActiveMq

I'm trying to connect an Android application to an ActiveMQ server. I'm using ActiveMQ because my server already talks to the ActiveMQ server using JMS so it will be very beneficial for me to connect the android client to the JMS broker.

I've enabled MQTT in ActiveMQ following this page: http://activemq.apache.org/mqtt.html and I had a small problem with any of the MQTT clients (IBM MQTT client or Paho MQTT Client) I've downloaded didn't recognize "mqtt://" url prefix so I tried to use tcp instead. This is how the configuration looks like in activemq.xml:

<transportConnectors> <transportConnector name="openwire" uri="tcp://0.0.0.0:61616?maximumConnections=1000&amp;wireformat.maxFrameSize=104857600"/> <transportConnector name="amqp" uri="amqp://0.0.0.0:5672?maximumConnections=1000&amp;wireformat.maxFrameSize=104857600"/> <transportConnector name="mqtt" uri="tcp://0.0.0.0:1883"/> </transportConnectors>

When I try to connect using any mqtt client example such as this one: http://mosquitto.org/2011/11/android-mqtt-example-project/ I'm unable to connect to the ActiveMQ and I get an error on the server side:

It seems to me, on the contrary, that neither actor has its output redirected, since withOut will have finished executing long before println("II") is called. Since this is all based on DynamicVariable, however, I'm not willing to bet on it. :-) The absence of working code precludes any testing as well.

I was struggling with same exception and found this:

When there is no protection level explicitly specified on the contract and the underlying binding supports security (whether at the transport or message level), the effective protection level for the whole contract is ProtectionLevel.EncryptAndSign. If the binding does not support security (such as BasicHttpBinding), the effective System.Net.Security.ProtectionLevel is ProtectionLevel.None for the whole contract. The result is that depending upon the endpoint binding, clients can require different message or transport level security protection even when the contract specifies ProtectionLevel.None.

So, if you don't specify ProtectionLevel in ServiceContract attribute, WCF will define ProtectionLevel based on your web.config. If you're using for example Ws2007 and BasicHttpBinding, BasicHttpBinding will fail with your exception. Then you have 3 options:

Remove all secured bindings for your contract and leave just BasicHttpBinding.
Set protection level on contract that is exposed through BasicHttpBinding as this:

[ServiceContract(ProtectionLevel = ProtectionLevel.None)]
Provide some security for BasicHttpBinding.

16497020 0 .Net MVC binding dynamic Type to a Model at runtime

I have a slightly long conceptual question I'm wondering if somebody could help me out with.

In MVC I've built a website which builds grids using kendoui's framework.

All the grids on my website are constructed exactly the same except for the model they use and the CRUD methods that need to be implemented for each model. I set things up where each Model implement an interface for CRUD methods like below to get the logic all in one place.

//Actual interface has variables getting passed public interface IKendoModelInterface { void Save(); void Read(); void Delete(); } public class Model1: IKendoModelInterface { [Key] public int IdProperty1 { get; set; } public int SomeProperty2 { get; set; } public string SomeProperty3 { get; set; } public void Save(){ //Implement Save } public void Read(){ //Implement Read } public void Delete(){ //Implement Delete } }

Then to speed up the writing of all the scaffolding Action methods needed to get the grids to work I created an abstract Controller that can call the interface methods of the Model that gets passed into it.

 //Implement the AJAX methods called by the grid public abstract class KendoGridImplController<T> : Controller where T : class, IKendoModelInterface { // Method called from kendo grid public virtual ActionResult Create([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<T> createdRecords) { //Invoke Create Method for Model and return results } public virtual ActionResult Read([DataSourceRequest]DataSourceRequest request, int Id) { //Invoke read method for model and return results } //Update and Delete also implemented.. }

Then I just need a Controller per model that implements the abstract controller above passing in the type of Model being used.

 public class ResponsibilityMatrixController : KendoGridImplController<Model1> { //Set up the page the grid will be on public ActionResult Index(int id) { return View("SharedGridView", id); } //Can override abstract methods if needed but usually won't need to }

I'm wondering if I can take this one step further or if I've reached the end of the road. To me it just seems like more repeated code if I have to create a controller per Model that does nothing but pass in the type to the abstract controller and calls the same View.

I attempted for quite a while yesterday to figure out if I could dynamically assign the type to the abstract controller. I setup something where I was sending back the type of model via strings and I could still invoke the methods needed. Where it failed, was that the mapping could no longer be done on any of the controller actions by default since the type isn't known at compile time. eg

public virtual ActionResult Create([DataSourceRequest] DataSourceRequest request, [Bind(Prefix = "models")]IEnumerable<T> createdRecords)

createdRecords can't be bound like this if T that's passed in is an interface and not the Model itself and I've found no real way to map the form data to an instance of a type that isn't known at compile time.

I'm wondering if there's an easy way to do this mapping between an instance of the type of object getting passed in that I can figure out at runtime, if there's some other way to set this up that I'm overlooking or if both those things are going to be way too much work and I should just not attempt something like this and build a controller per model like I do now?

The OutOfMemoryException is almost certainly coming from the JSON serialization of your Customer object. As such, the issue isn't one of NEST or Elasticsearch functionality, but of JSON.NET functionality.

You could handle this in one of two ways:

1. Serialize the large object selectively

This article by the author of JSON.NET discusses reducing the size of objects. You might furnish properties with the JsonIgnoreAttribute property to instruct the serializer to ignore certain properties. Or an implementation of IContractResolver may be less intrusive on the definitions of your EF objects (especially given that they're database-first generated), but I'm not sure whether this can be used in conjunction with the NEST dependency on JSON.NET.

If you're out of options for dealing with NEST's dependency on JSON.NET, you could always find another way to serialize your object and "go raw" by using the Elasticsearch.NET syntax instead of NEST (which essentially builds on-top of Elasticsearch.NET). So instead of a call to ElasticClient.Index(..), make a call to ElasticClient.Raw.Index(..), where the body parameter is a JSON string representation (of your own construction) of the object you wish to index.

2. Project the large object to a smaller data transfer object

Instead of indexing a Customer object, map only the properties you want to index into a data transfer object (DTO) that targets your Elasticsearch schema / document type.

foreach (Customer c in db.Customer.Where(a => a.Active == true)) client.Index(new MyElasticsearchTypes.Customer() { CustomerId = c.CustomerId, CustomerName = c.CustomerName, Description = c.Description });

In C#, you've got a lot of options for how to handle creation of such a DTO, including:

Explicitly typed objects with manual mapping (like my example).
Explicitly typed objects with a mapping tool like AutoMapper.
Dynamic objects.

Flat by design

Be aware that using Elasticsearch isn't a case of simply throwing your data into "the index". You need to start thinking in terms of "documents", and come to terms with what that means when you're trying to index data that has come from a relational database. The Elasticsearch guide article Data In, Data Out is a good place to start reading. Another article called Managing relations inside Elasticsearch is particularly relevant to your situation:

At it's heart, Elasticsearch is a flat hierarchy and trying to force relational data into it can be very challenging. Sometimes the best solution is to judiciously choose which data to denormalize, and where a second query to retrieve children is acceptable

I only see a message saying… “No test discovered. Please build your project and ensure the appropriate test framework adapter is installed”.

I assume the MSTest adapter is automatically installed. If not I’m not even sure how to install an adapter.

I could be missing something here but I cannot figure it out. Has anyone experiencing this issue?

With this query your first row, or the row that uNo = 1 has the sum of older debits and credits.

Somehow after reinstallation of my arch linux, vim stoped work poperly. After doing the same I did couple days ago with old system - now python complains about indentation.

I have no installed plugins or whatever, why does this broke?

P.S. already viewed same quiestions, but them was about plugins, which I doesn't have. P.S. Noticed that after : vim won't start newline according cindent

Still indentation brokes after :set paste. Why this happens?

35779528 0 Get the number of time a moq method has been called

It's possible to use myMock.Verify(m => m.f(It.IsAny<string>()), ...); to assert that the method f(string s) has been called at least / at most / exactly n times.

I want to do something a bit more complicated: I want to ensure that the number of calls to f(string s) plus the number of calls to f(int i) is equal to 3.

Is there an lightweight way to do it with Moq?

More details

Actually I can think of a way to do it: I could setup a callback that would increment a counter when each of those methods is used. However it would require more set up in the test, which could hinder it's readability. (And it would be a shame to re-implement something that could already be implemented in moq).

For instance a lightweight way to do it could be to be able to retrieve the exact number of call to my method, so that I could Assert.AreEqual on it. But I haven't been able to find a way to do it so far.

40344960 0 Post relational data, Spring JPA REST

I have a relational database with a normalized form of my data, but my API will need to receive the information in a denormalized way, what is the correct way to handle this? Is it a matter of creating a new endpoint with the fields denormalized?

How would I decouple that from the database so that Spring Boot doesn't create a new table for me?

For example, here are (some of) my tables:

@Entity public class TestCase { @Id @GeneratedValue(strategy = GenerationType.AUTO) private long id; private String name; private String description; } @Entity public class TestRun { @Id @GeneratedValue(strategy = GenerationType.AUTO) private long id; private Boolean result; private String username; @OneToOne private TestData testData; @ManyToOne private TestCase testCase; } @Entity public class TestData { @Id @GeneratedValue(strategy = GenerationType.AUTO) private long id; private int count; @ManyToOne private RecordType recordType; }

I want to create an API endpoint that will create new entries in TestRun and TestData at the same time, while referencing existing entries in TestCase and RecordType.

How is this done?

A complete answer needs to show:

What format the data would take when its posted to the server
What component will handle that post
How that component will update the different Entities

The "DEMO" files you're referring to are found in the "Examples" folder in that GitHub Repo.

For your own use, you will need to take those demo files and modify them for your use and then drop them into your own project.

As for your "homeViewController.m" file, I would imagine you'd replace the first line of that code with something like:

DEMONavigationController *navigationController = [[DEMONavigationController alloc] initWithRootViewController:[[homeViewController alloc] init]];

(by the way... you should name your Objective-C classes and files with capital letters. It's methods, properties and variable names that should start with lower case letters).

In third window (i think its officially called story) there is a Done button.

How to make that button return an object with text on screen and return to window 2? There, i window 2 the table should refries, but that is out of the scope of this question.

What i did was to implement IBOutlet in ThirdWindowViewController (lets call it that), which is linked to IBAction method.

@property (nonatomic, strong) IBOutlet UITextView* textView; @property (nonatomic, strong) Note* note; @property (nonatomic, retain) IBOutlet UIBarButtonItem* doneButton; - (void) configureView; - (IBAction) doneAction:(id)sender; - (BOOL) prepareNoteForTransition;

As Tom wrote, you need a delegate. That is the way i actually did it, with methods i put above. I just thought that there is some more apple-specific way to do it, like that Segues. or some alternatives.

38500580 0 when enabling errors to bigquery I do not receive the bad record number

I'm using bigquery command line tool to upload these records:

{name: "a"} {name1: "b"} {name: "c"}

➜ ~ bq load --source_format=NEWLINE_DELIMITED_JSON my_dataset.my_table ./names.json

this is the result I get:

Upload complete. Waiting on bqjob_r7fc5650eb01d5fd4_000001560878b74e_1 ... (2s) Current status: DONE BigQuery error in load operation: Error processing job 'my_dataset:bqjob...4e_1': JSON table encountered too many errors, giving up. Rows: 2; errors: 1. Failure details: - JSON parsing error in row starting at position 5819 at file: file-00000000. No such field: name1.

when I use bq --format=prettyjson show -j <jobId> I get:

 { "status": { "errorResult": { "location": "file-00000000", "message": "JSON table encountered too many errors, giving up. Rows: 2; errors: 1.", "reason": "invalid" }, "errors": [ { "location": "file-00000000", "message": "JSON table encountered too many errors, giving up.

No such field: name1.", "reason": "invalid" } ], "state": "DONE" } }

As you can see I receive an error which tells me in what line I had an error. : Rows: 2; errors: 1

Now I'm trying to enable errors by using max_bad_errors

 ➜ ~ bq load --source_format=NEWLINE_DELIMITED_JSON --max_bad_records=3 my_dataset.my_table ./names.json

here is what I receive:

Upload complete. Waiting on bqjob_...ce1_1 ... (4s) Current status: DONE Warning encountered during job execution: JSON parsing error in row starting at position 5819 at file: file-00000000. No such field: name1.

when I use bq --format=prettyjson show -j <jobId> I get:

when I check - it actually uploads the good records to the table and ignores the bad record,

but now I do not know in what record the error was.

Is this a big query bug? can it be fixed so I receive record number also when enabling bad records?

I am not sure but I have a feeling your problem is in the selector you are passing to the button.

Try to see if you are using a selector with ":" to a method with out parameters.

If you are using selector that looks like this:

@selector(method:)

Then is is expected that "method" will take parameters:

-(IBAction)method:(UIButton)sender{ }

if your function is not taking any parameters:

-(IBAction)method{ }

then your selector should look like that:

@selector(method)

41020613 0 How similar are boost::filesystem and std::filesystem?

I believe boost::filesystem was at least one of the "source" libraries used to design std::filesystem for C++17.

How similar are they? If very similar, what are the known gotchas and incompatibilities? If not, where are they similar?

This is in the context of implementing something with std::filesystem, std::experimental::filesystem or boost::filesystem, and wanting to know the likely scope of efforts required if we switch libraries (say, if one discovers that the std library on a particular platform is inadequate).

This is not a request for an alternative library recommendation.

By HTML specifications, you cannot use a link element inside the body element. You should arrange things so that link elements appear inside the head element. In the given context, you can achieve this by omitting the div class=body markup (it should not be needed, though omitting it may require changes to your CSS code) as well as the </head> and <body> tags. There are probably smarter ways to achieve the goal, though.

Its not duplicate

I have a python code that uses speech recognition and it has a problem when microphone is off so i want to add a code that closes python if microphone is off and if its not then runs the whole script.

for example:

import speech_recognition as sr #if microphone is on : r = sr.Recognizer() with sr.Microphone() as source: audio = r.listen(source) try: said = r.recognize_google(audio) print(audio) except sr.UnknownValueError: print('google did not understand what you said') except sr.RequestError as e: print('errpr' + "; {0}".format(e)) #else print('please turn your microphone on and open again') quit()

any ideas how to do that?

Its not a duplicate question and it's completely a different question

In this link : we can detect that microphone is connected to pc or not , i wanna detect that microphone button is on or off.

Actually my codes has this error that when my microphone is off and i run the code then i turn that on while code is still running , it will not recognize my voice , so i want to warn user to turn his microphone on then restart program.

For types smaller than the size of a pointer (e.g. int), passing by value is more efficient.
For types bigger than the size of a pointer (e.g. most struct or class instances), passing by reference is probably more efficient (only "probably" because on top of the cost of passing the parameter, potentially constructing an object, you incur the cost of dereferencing your parameter every time you use it).

More details about passing-by-value vs. passing-by-reference can be found in this question. More details about reference vs. pointer arguments can be found in that question.

Starting from KitKat, you have access to a method to get that directory :

Context.getExternalFilesDirs()

Note that it may return null if the SD card is not mounted or moved during the access. Also, you might need to add these permissions to your manifest file :

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

It looks to me as though you are having problems with understanding how to create a recursive operation for your folders. I'll try to give you an example of how I would handle this. Given my example may not be the best.

public static final String NAME = "Demo-Folder"; public static final String PARAM_ASPECT_NAME = "folder-name"; private NodeService nodeService; /** * Set the node service * * @param nodeService the node service */ public void setNodeService(NodeService nodeService) { this.nodeService = nodeService; } public void executeImpl(Action action, NodeRef actionUponNodeRef) { ChildAssociationRef childAssociationRef = nodeService.getPrimaryParent(actionUponNodeRef); System.out.println("****The folder is***** "+ childAssociationRef); iterateThroughChildren(childAssociationRef); } public void iterateThroughChildren(ChildAssociationRef childAssocRef) { System.out.println("****The folder is***** "+ childAssocRef); NodeRef childNodeRef = childAssocRef.getChildRef(); List<ChildAssociationRef> children = nodeService.getChildAssocs(childNodeRef); for (ChildAssociationRef childAssoc : children) { childAssoc.getChildRef(); // Use childNodeRef here. System.out.println("******Documents inside are******"+ childAssoc); // This call recurses the method with the new child. iterateThroughChildren(childAssoc); // If there are no children then the list will be empty and so this will be skipped. } }

I used your code above, and extended it out to include a new method called iterateThroughChildren which takes the ChildAssociationRef and gets the children and iterates through them. During the iteration the children are passed back into the method to allow for their children to be iterated, and so on until there are no children (meaning you are at the end of a branch). This allows you to iterate through an entire tree structure.

Do you have an /app/templates/client-availibilities.hbs template with only {{outlet}} inside of it? Without this, the app is going to lose its place in the outlet tree. Ember-CLI and the Ember Starter Kit are very, very different from each other in structure, so I can see where the confusion comes from.

How I like to think of Ember's rendering style is that each handlebars file inside the templates folder (i.e. /templates/users.hbs) represents a change the overall state of the application from one subject to another (example: from newsfeed to users). The corresponding subfolders inside the templates folder change the state of the subject itself.

For example:

Required Templates
- Users container OR the only users page you need app-wide is at /templates/users.hbs
Optional Templates
- Users Index would be at /templates/users/index.hbs
- Users Show would be at /templates/users/show.hbs
- Users New would be at /templates/users/new.hbs

You can have [ /templates/users.hbs ] without having [ /templates/users/*.hbs ] and still keep track of your data; however, you cannot have [ templates/users/index.hbs ] without [ /templates/users.hbs ] and still keep track of your data. Why? Imagine if you navigate to somesite.com/users. There is currently no top-level template with an outlet into which Ember can render the [ users/index.hbs ] template. The [ /templates/users.hbs ] template bridges that gap and also serves as a container for all other pages inside the /templates/users folder as well.

For example, in the terms of your app, in order to render [ /app/templates/client-availibilities/index.hbs ] when a user visits http://www.yourwebsite.com/client-availibilities, your app will need these templates defined so that ember can drill down into them.

application.hbs // and in its outlet, it will render... --client-availibilities.hbs // and in its outlet, it will render by default... ----client-availibilities/index.hbs // then, for the client-availability (singular), you can have ember render it in ----client-availibilities/show.hbs // will render also in the client-availabilites as it is a separate state of the subject. Can also be nested inside the index route within the router so that it renders inside the index template.

As it is, I would structure your app as such...

/app/router.js

... // previous code Router.map(function() { this.resource('client_availabilities', function() { this.route('show', { path: '/:client_availability_id' }); // this.route('new'); ! if needed ! // this.route('edit', { path: '/:client_availability_id/edit' ); ! if needed ! }); }); ... // code

/app/templates/application.hbs

{{link-to 'Client Availabilities' 'client_availabilities'}} {{outlet}}

/app/templates/client-availabilities.hbs

{{outlet}}

/app/templates/client-availabilities/index.hbs

<ul> {{#each}} {{#if available}} <li> {{#link-to #link-to 'client-availabilities.show' this}} {{firstName}} {{lastName}} {{/link-to}} </li> {{/if}} {{else}} <!-- we want this to only render if the each loop returns nothing, which is why it's outside the if statement --> <li>Nobody is available</li> {{/each}} </ul> <!-- Note: you don't need to put an outlet here because you're at the end of the tree -->

/app/templates/client-availabilities/show.hbs

<!-- Everything you want to show about each availability -->> <!-- Note: you don't need to put an outlet here because you're at the end of the tree -->

/app/routes/client-availabilities/index.js

import Ember from 'ember'; export default Ember.Route.extend({ model: function() { return this.store.findAll('client_availability'); } });

/app/routes/client-availabilities/show.js

import Ember from 'ember'; export default Ember.Route.extend({ model: function(params) { return this.store.find('client-availability', params.client_availability_id); } });

/app/models/client-availability.js

import DS from 'ember-data'; var client-availability = DS.Model.extend({ firstName: DS.attr('string'), lastname: DS.attr('string'), available: DS.attr('boolean'), available_on: DS.attr('date') }); export default client-availability;

However, are you sure you want to structure your app by the availability of each client? Wouldn't it make more sense to structure it by each client and then just filter each client to show if they were available or not? Resources are supposed to be nouns, and routes are supposed to be adjectives. Therefore, it would be best to use a client as your model instead of their availability and have a either an isAvailable property on the model (as used in the example above) or a one-to-many association with an additional availability model if you want to show clients who have several availabilities (as shown below).

For example,

/app/models/client.js

import DS from 'ember-data'; var Client = DS.Model.extend({ firstName: DS.attr('string'), lastName: DS.attr('string'), availabilities: DS.hasMany('availability') }); export default Client;

/app/models/availability.js

 import DS from 'ember-data'; var Availability = DS.Model.extend({ date: DS.attr('date'), client: DS.belongsTo('client') }); export default Availability;

In the long run, this latter approach would set up your app to show all availabilities at once and allow the user to filter by the client, plus it would allow the user to view a client and see all their availabilities. With the original approach (the isAvailable property on the client model), the user can only get the availabilities from the client model itself, but what if the user wants to see all clients who are available on, say, March 3rd at noon? Well, without an availability model associated with the client model, you are going to have to put a lot of code into your client controller that ember would give you by default if you go down the one-to-many path.

If you need more advice on where to go from here, let me know. I'm more than happy to add more examples of the templates, controllers, and routes that you'll need in order to pull this off.

Ok I wasn't really sure how to word this question, but basically what I want to do is, I got a url from a RSS feed in android, and I need to put part of that url into a string, the url will look something like this: http://www.prsn.uprm.edu/Spanish/Informe_Sismo/myinfoGeneral.php?id=20161206012821' and I only want the part after id= ONLY THE ID NUMBER,Then I need the id to put it in the following url: http://shake.uprm.edu/~shake/archive/shake/**ID HERE**/download/tvmap.jpg, to load the image corresponding to the id in Glide: [Solved] This Part is solved but i have a other Problem

I have to ways to do this

First Way:

 //the original String String somestring = "http://www.prsn.uprm.edu/Spanish/Informe_Sismo/myinfoGeneral.php?id=20161206012821"; //save the index of the string '=' since after that is were you find your number, remember to add one as the begin index is inclusive int beginIndex = somestring.indexOf("=") + 1; //if the number ends the string then save the length of the string as the end, you can change this index if that's not the case int endIndex = somestring.length(); //Obtain the substring using the indexes you obtained (if the number ends the string you can ignore the second index, but i leave it here so you may use it if that's not the case) String theNumber = somestring.substring(beginIndex,endIndex); //printing the number for testing purposes System.out.println("The number is: " + theNumber); //Then create a new string with the data you want (I recommend using StringBuilder) with the first part of what you want StringBuilder sb=new StringBuilder("http://shake.uprm.edu/~shake/archive/shake/"); // add the number sb.append(theNumber); //then the rest of the string sb.append("/download/tvmap.jpg"); //Saving the String in a variable String endResult = sb.toString(); //Verifying end result System.out.println("The end result is: "+endResult); Glide.with(context).load(endResult).into(holder.Thumbnail);

Second Way:

String url = "http://www.prsn.uprm.edu/Spanish/Informe_Sismo/myinfoGeneral.php?id=20161206012821"; String[] array = url.split("id="); String id = array[1]; String urlToLoad = "http://shake.uprm.edu/~shake/archive/shake/"+id+"/download/tvmap.jpg" Glide.with(context).load(urlToLoad).into(holder.Thumbnail);

[Problem]

My problem is, if i put the URL normally, ie http://www.prsn.uprm.edu/Spanish/Informe_Sismo/myinfoGeneral.php?id=20161206012821 the two methods work for me, but if I get the url Via getLink() does not work for me. Please help me.
I hope I explained well. Thanks in advance.

There is my Myadapter.java the method to get the link is current.getLink()

17843882 0 php search result images show across and fill a CSS div

I'm using dreamweaver and php to return a list of images based on search critiera. I have used Dreamweaver's repeat function and can get the images to repeat below each other (as below).

<table width="100" height="38" border="1"> <?php do { ?> <tr> <td width="38"> <img class='example' src="images/<?php echo $row_getresult['image_name']; ?>.png"/><br> </a></td></tr> <?php } while ($row_getamenityaccommodation = mysql_fetch_assoc($getamenityaccommodation)); ?> </table>

How can I get the images to go across from each other within a CSS Div e.g. float:left; width:45%; so that if there are more images than what would fit in 45%, the images would continue onto a new line?

Would somehow 'printing' the array work?

Because you cannot declare class properties with variable expressions. That means you cannot use any arithmetic operators + - * / or the concatenation operator ., and you can't call functions. Out of your three lines, only $test should work; the other two will give you errors.

If you need to build your strings dynamically, do it in the constructor.

class Object { public $test = "Hello"; public $var2; public function __construct() { $this->var2 = $this->test . "World"; } }

By the way, . is not a "string separator". It's the concatenation operator. You use it to join strings, not separate them.

15813189 0 Using jquery .next() with javascript generated content selector not working

So, I have gone round and round on this issue and all I can come to is that this is an inherent flaw in jquery, but I'm posting this question here as a last resort.

Here's the 1,000 ft view of the project. I'm making a slideout feature similar to the new Google Image search results. I have a grid of boxes, some that expand for deeper content and some that do not. The way I am accomplishing this is by running the below javascript to dynamically add 'row' divs below each row of grid boxes that has expandable content.

function defineFocusRowLength() { var rowFocusBoxCount = 0; $('#isofocus .focusbox.core').each(function(){ rowFocusBoxCount++; if($(this).css('float') === 'right') { finalFocusRowBoxCount = rowFocusBoxCount; return false; } }); $('#isofocus .slidecontent').remove(); $('#isofocus .focusbox.core:nth-child('+finalFocusRowBoxCount+'n)').after('<div class="slidecontent"><div class="wrap"></div></div>'); if($('#isofocus .focusbox.core').last().css('float') === 'right') { // do nothing because it should have been caught by the previous line } else { $('#isofocus .focusbox.core').last().next('.focusbox').each(function(){ if($(this).css('float') === 'right') { if($(this).next('.focusbox').css('float') === 'right') { $(this).next('.focusbox').after('<div class="slidecontent"><div class="wrap"></div></div>'); } else { $(this).after('<div class="slidecontent"><div class="wrap"></div></div>'); } } }); } } defineFocusRowLength(); $(window).resize(function() { defineFocusRowLength(); });

In case you are wondering, I am calling this function on window.resize as well because my site is responsive, so as the grid reorganizes this function removes the old expanded rows and creates new ones in the appropriate spaces.

This part of my code all works beautifully. No problems whatsoever. However, it's when I try to target these new divs with .next() that completely fails.

Here is the code I execute when you click the in each box:

$(".focusbox a.popup").click(function(){ var expandtext = $(this).parents('.focusbox').children('.expanded-content').html(); $(this).parents('.focusbox').next('.slidecontent').html(expandtext); $(this).parents('.focusbox').next('.slidecontent').slideToggle(); })

Now, I have tried about 20 other variations of this code and they work. It is just this specific way I am needing it to work that fails. Here are some of the variations I used that worked, but were not the proper result:

$(this).parents('.focusbox').next().slideToggle(); //works, but slides up the next box, not the expanded row $(this).parents('.focusbox').siblings('.slidecontent').slideToggle(); //works but shows all expanded rows $(this).parents('#isofocus').find('.slidecontent').slideToggle(); //works but shows all expanded rows

So yeah, I'm pretty much at my wits end here and believe that this is just inherintly a flaw in jquery that the .next() function is unable to access selectors of content that is generated after page load, even if the function is not called until after the page has loaded.

Here is my jsfiddle for you to take a stab at it: http://jsfiddle.net/RCVfK/1/

Found a workaround. I am using this method on ubuntu so paths may be different for other os.

Go to /usr/lib/node_modules/ionic/lib/ionic

Open serve.js with root user.

Find function called IonicTask.prototype.getAddress

Inside this function the value of variable isAddressCmd is false. Set it to true

self.isAddressCmd = false;

save the file. Now run Ionic serve for your project. This time it will ask for localhost vs ip again.

After this remove the newly added code from serve.js otherwise ionic serve won't work.

35288013 0 Recyclerview viewholder possible to change views at other adapter positions (not current position)?

I have a recyclerview with mediaplayer to play a song on each row. I only have one button for play/stop which changes symbol.

Here is my problem:

Example 1 (This works fine):

(For adapter position 1) the user hits the play symbol and music plays for that adapter position and the symbol changes to a stop symbol, they then hit the stop symbol and the music stops and the symbol changes back to a play symbol ready to start the music again.

Example 2 (This is the problem)

(For adapter position 1) the user hits the play symbol and music plays for that adapter position and the symbol changes to a stop symbol. Without hitting that button again they then hit the play symbol (adapter position 3) so now they are trying to play the song on position 1 and 3 at the same time. I have fixed both songs playing at the same time so that when the the second song is pressed the media played is reset and the source song file is changed to the new song (only one will play at a time).

The problem then becomes even though the media player is behaving as it should. The mediaplayer is controlled in the mainactivity. The play/stop button (imageview) image is changed in the the adapter viewholder and I can't work out a way to change the play/stop symbol when more than one song is clicked at the same time.

This image shows the example both song 1 and song 3 have been pressed. Now only song 3 is playing but the images are still showing as if both songs are playing simultaneously.

This is my view holder where I handle changing the play/stop image and send the song clicked callback:

class AddVideoAudioViewHolder extends RecyclerView.ViewHolder{ ImageView PlayButton; Button AddAudioButton; TextView Title; public AddVideoAudioViewHolder(View itemView) { super(itemView); PlayButton = (ImageView) itemView.findViewById(R.id.PlayStopAudioDemo); PlayButton.setTag(1); PlayButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { int PlayStopButtonState = (int) PlayButton.getTag(); if (PlayStopButtonState == 1) { mVideoAudioCallbacks.onClick(100 + getAdapterPosition()); PlayButton.setImageResource(R.drawable.playstop); PlayButton.setTag(2); } else { mVideoAudioCallbacks.onClick(200 + getAdapterPosition()); PlayButton.setImageResource(R.drawable.playarrow); PlayButton.setTag(1); } } });

and this is the method in the main activity where I handle the case of two songs playing:

public void PlaySong (int SongNumber, int ObjectInt){ if (mp == null) { mp = new MediaPlayer(); }else{ mp.reset(); } try { mp.setDataSource(this, Uri.parse("android.resource://com.example.nick.accountable/" + SongArray[SongNumber])); } catch (IOException e) { e.printStackTrace(); } try { mp.prepare(); } catch (IOException e) { e.printStackTrace(); } mp.start(); }

So my question can I add some code in the view holder or in the main activity that can change all the other views than the current adapter position. I.e. If song number 3 is clicked to play, set the image for position 1-2 & 4-10 as not playing or is there a better way to do it.

Thanks for your help Nicholas

24025641 0 Passing array from system verilog to VHDL

I have a code in VHDL which requires an array of elements as generic. COEF_LIST : coef :=(0,0,1,1,2,-2,1,-2,1)

How do I send new set of COEF_LIST from my system verilog testbench to VHDL entity?

Generic in VHDL is same as parameter in verilog.

I declared coef as

 parameter real COEFF[8:0] = '{0,0,1,1,2,-2,1,-2,1};

in system verilog.

I tried passing using (in my verilog testbench)

 vhdl_entity #( .COEF_LIST(COEFF) )

I get the following error

Avoid exit; / function exit; or die; will terminate execution, its better practice in only debugging your code.

Try like below.

public function index(){ if($xx) return TRUE; }

20504851 0 Using xcodebuild with an iOS Project and the iOS Simulator

This question is related, but does not resolve the specific issue I am having.

I am using Xcode 4.6.3 under OS X 10.7.5.

I simply created the default project for a single view iOS app and made no changes to the project settings. The project, of course, builds in Xcode for the iOS Simulator. However, when I try to use xcodebuild from the command line, xcodebuild fails.

The project name is just: temp

I tried:

xcodebuild -scheme temp -sdk iphonesimulator6.1

and that produced the results:

Build settings from command line: SDKROOT = iphonesimulator6.1 === BUILD NATIVE TARGET temp OF PROJECT temp WITH CONFIGURATION Debug === Check dependencies No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=i386). ** BUILD FAILED ** The following build commands failed: Check dependencies (1 failure)

Based on the other SO question, I tried:

xcodebuild ARCHS="armv7 armv7s" ONLY_ACTIVE_ARCH=NO -scheme temp -sdk iphonesimulator6.1

and got similar results:

Build settings from command line: ARCHS = armv7 armv7s ONLY_ACTIVE_ARCH = NO SDKROOT = iphonesimulator6.1 === BUILD NATIVE TARGET temp OF PROJECT temp WITH CONFIGURATION Debug === Check dependencies No architectures to compile for (ARCHS=armv7 armv7s, VALID_ARCHS=i386). ** BUILD FAILED ** The following build commands failed: Check dependencies (1 failure)

What xcodebuild command do I need to execute to be able to build with xcodebuild?

Thank you.

You would have to some how invoke a compiler (such as Suns javac), parse its output in case of errors and load the resulting classes dynamically.

There is no API-classes in the Java runtime library that will parse, compile and run Java source code.

The end result I am trying to do is to get the JSON back from this get request as well - it may need to be a separate question but I am also having issues with getting the JSON contents from the response body.

SVN command line errors go to stderr, not stdout, which is why you aren't able to see them. What you want to do is redirect stderr to stdout and then print_r($output) to determine the cause of the error.

exec('svn commit <stuff> 2>&1', $output, $returnStatus); if ( $returnStatus ) { print_r($output); }

Sample output:

Array ( [0] => svn: Commit failed (details follow): [1] => svn: '/path/to/<stuff>' is not under version control )

This is not ideal because it mixes stderr with stdout when it would otherwise be unnecessary, but I don't know of another way to get the desired output in this case. If someone else does, please comment.

Note: The third parameter to exec(...) is the return status, not the error message, so you need to tweak your code accordingly for that as well.

If the error output after making the 2>&1 modification doesn't help solve the root cause of your problem, please post the new output here.

Edit after new information:

Did you upload this SVN working copy to your server from somewhere else? That would explain this error.

If I check out a working copy from my local repository, upload it to my remote server, and then try to commit, I get the same error.

If that's the case, you need to execute the "svn checkout" of the working copy on the server running the PHP script in order to be able to commit to it. If that server can't communicate with the repository's server, then that's a whole other problem.

You can express your query as:

SELECT IdPerson FROM Person p JOIN CustomFieldXPerson cfxp on cfxp.IdPerson = p.IdPerson JOIN Filter f on f.IdField = cfxp.IdField AND (f.Criteria = '=' and f.Value = cfxp.Value or f.Criteria = '<' and f.Value < cfxp.Value or f.Criteria = '<=' and f.Value <= cfxp.Value or f.Criteria = '>' and f.Value > cfxp.Value or f.Criteria = '>=' and f.Value >= cfxp.Value ) WHERE f.GroupId = X ;

EDIT:

If you want to get persons that match all filters, just use group by:

SELECT IdPerson FROM Person p JOIN CustomFieldXPerson cfxp on cfxp.IdPerson = p.IdPerson LEFT JOIN Filter f on f.IdField = cfxp.IdField AND (f.Criteria = '=' and f.Value = cfxp.Value or f.Criteria = '<' and f.Value < cfxp.Value or f.Criteria = '<=' and f.Value <= cfxp.Value or f.Criteria = '>' and f.Value > cfxp.Value or f.Criteria = '>=' and f.Value >= cfxp.Value ) AND f.GroupId = X GROUP BY idPerson HAVING COUNT(f.IdField) = COUNT(*) OR COUNT(f.IdField) = 0;

In other words, all the filters that match the person, in the group, match. The additional condition in the HAVING clause is in case the filter group has no filters.

The general strategy here is that you want to maintain a context as you traverse the list, and at each step, you use that piece of context to answer the question of whether the current item should be kept or thrown out. In pseudo-code:

public static <A> List<A> removeDuplicates(List<? extends A> original) { List<A> result = new ArrayList<A>(); /* initialize context */ for (A item : original) { if ( /* context says item is not a duplicate */ ) { result.add(item); } /* update context to incorporate the current `item` */ } return result; }

Some people have brought up the question of whether you mean consecutive duplicates or non-consecutive ones. In reality, the difference in the solutions is small:

For consecutive duplicates the context is the most recently seen item.
For non-consecutive it's the Set<A> of all items seen up to that point.

I'll let you fill in the pattern for those cases.

The problem is that facebook like will extract meta info but I don't know how to assign the meta with ajax.

I tried use append to head int FB.init but it seems not work.

Of course this does not work, because Facebook’s scraper requests your URLs from your server – and does not care about what the DOM might currently look like in any user’s browser.

You can not add Open Graph meta data client-side.

Second: files is a list in your example

1915342 1 Python: List of lists of integers to absolute value to single number

If i had a list of list of integers say:

[['12' '-4' '66' '0'], ['23' '4' '-5' '0'], ['23' '77' '89' '-1' '0']]

I wanted to convert the numbers to their absolute values and then to a single number, so the output would be:

16141778 0 c# Many Unmanaged Memory in WinForm Application

I've a c# winform application. Now after startup when the mainscreen is shown, I've a huge amount of unmanaged memory about 110MB, the whole managed ram is about 20 MB.

Here some things that could be uncommon:

The application consists of many assemblies which are in total 98 MB file size.
Some Forms have a wpfhost, but which are loaded this time (but perhaps some other WPF framework libraries)
The Ram does not seem to be growing.
There are a lot strings shown many of them are part of the WPF like "margin"
The Main form is quite big and has a infragistics datagrif with about 30 Rows.

When I load all assemblies with Assembly.Load in a console app they only cost 1 MB of unmanaged ram.

Where can this unmanaged memory come from ? Can someone give me a hint on what kind of elements could be involved?

You do the math before you read the input. You need to do it the other way around.

Also, there's no reason to pass a meaningless and uninitialized value to the celsius function.

Lastly, 180/100 is 1 remainder 80 because when you divide two integers, you get integer division. You can use 180.0/100.0.

Basically, you need to learn C.

Unicode character U+25BC is a solid triangle pointing down: ▼. You can also finagle html block elements to look like triangles by giving them a width and height of zero and applying special border properties to three of the element's sides. This technique is known as the CSS triangle hack.

Instead of using MODIFY, use a field symbol:

DATA: lt_materials TYPE TABLE OF zzllog. FIELD-SYMBOLS: <ls_line> TYPE zzllog. * other code with strange comments :-) LOOP AT lt_materials ASSIGNING <ls_line> WHERE matnr IS INITIAL. SELECT SINGLE MATNR FROM zlldet INTO <ls_line>-matnr WHERE palet = <ls_line>-palet. ENDLOOP.

This is just an example for the correct syntax. It's not a good idea to do this in a real program because there's a fair chance thtat you'll be hitting the database with thousands of requests, and potentially draw quite a bit of performance. It'd be better to preselect the PALET numbers that have no MATNR into a separate table and then use FOR ALL ENTRIES IN to read all the MATNRs in a single query.

EDIT: Added type names. BTW, your way of declaring the internal table is somewhat outdated...

ngModel does not create a new isolated scope for itself so it can $watch without having to hardcode a $parent in it's internal code. But then you add another directive on the same DOM node that creates an isolated scope for itself. Couple this with the fact that you can only have a single isolated scope on a DOM node and you basically force ngModel to use/work with the same scope cmPopover created.

So when writing ng-model="currentEditItem.strFirstName" you are actually addressing the $scope inside the cmPopover directive, no the one in the (parent) controller. You can check this is the case by using ng-model="$parent.currentEditItem.strFirstName" - and it will work.

There's quite a lengthy conversation here with a lot of possible workarounds and solutions that leads to an actual fix in release 1.2.0.

So long story short: update to at least AngularJS 1.2.0 and this will work.

I'm quite new on that and I don't know if I am understanding your question, but why you don't use "backticks" instead of "system"? It would let you store the output in a variable and then you can do with this variable whatever you want.

It can also be caused by this bug, if you're having Eclipse 4.5/4.6, an Eclipse Xtext plugin version older than v2.9.0, and a particular workspace configuration.

The workaround would be to create a new workspace and import the existing projects.

I set up objects to handle my downloads (and other asynchronous or long running tasks) in the AppDelegate, then trigger them as required from various controllers. That way they are owned and have persistence through the life of the application.

The best way to do this is to pass them to the viewControllers that will need them (rather than the viewController "expecting" the appDelegate to have such and such an object ready and waiting) - dependency injection.

These objects update my model in some way when they finish and if I need to, I use NSNotifications to announce they are done. This isolates me from the mess I used to get into trying to cancel or swap delegates in viewWillDisappear etc to avoid the kind of issues you are running into.

25640956 0 tooltip inside popover stays after popover is closed - ZeroClipboard

I'm trying to add buttons to popover that will allow user to copy content.
I managed to build prototype: http://jsfiddle.net/Misiu/VUZhL/890/ but I have weird error when using tipsy inside popover:

enter image description here

After clicking on Click for action button I get popover with 2 buttons, they both have tooltips, sometimes after clicking on button tooltip stays visible.

My code:

$(function () { $('#example').tipsy({ title: 'data-tipsy-title', gravity: function () { return this.getAttribute('data-tipsy-gravity') || 'n'; } }); $(document).on('click', '#example, .tip', function (event) { $(this).tipsy("hide"); }); $('#example').popover({ placement: 'top', title: '', html: true, template: '<div class="popover" role="tooltip"><div class="arrow"></div><div class="popover-content no-padding"></div></div>', content: '<div class="btn-group">' + '<button type="button" title="link" class="btn btn-default tip number"><span class="fa fa-link"></span></button>' + '<button type="button" class="btn btn-default tip" title="something else"><span class="fa fa-copy"></span></button>' + '</div>' }); $('#example').on('shown.bs.popover', function () { //tipsy $('.tip').tipsy({ gravity: 's' }); //zero clipboard var clip = new ZeroClipboard($(".tip")); clip.on("copy", function (event) { var clipboard = event.clipboardData; var data = ""; if ($(event.target).hasClass("number")) { data = "1st button"+new Date() } else { data = "second"; } clipboard.setData("text/plain", data); ZeroClipboard.deactivate(); }); }) //zero clipboard ZeroClipboard.config({ hoverClass: "hover" }); });

My questions:
1. How can this be fixed?
2. Is ZeroClipboard initialized in right place? I can't do that before, because buttons are added when popover is shown for first time.

24743758 1 Pygame Large Surfaces

I'm drawing a map of a real world floor with dimensions roughly 100,000mm x 200,000mm.

My initial code contained a function that converted any millimeter based position to screen positioning using the window size of my pygame map, but after digging through some of the pygame functions, I realized that the pygame transformation functions are quite powerful.

Instead, I'd like to create a surface that is 1:1 scale of real world and then scale it right before i blit it to the screen.

Is this the right way to be doing this? I get an error that says Width or Height too large. Is this a limit of pygame?

//Your example json results = [{"type":"fruit", "name":"orange"},{"type":"flower","name":"rose"},{"type":"fruit", "name":"apple"}]

First you need to turn your json into an array of dictionaries to get the above object you think it will be:

if let results = try NSJSONSerialization.JSONObjectWithData(data,options: NSJSONReadingOptions.MutableContainers) as? [[String : AnyObject]] { //parse into form you want.} // Your example desired result of dictionary with key:array of dictionaries updatedResult[String:[AnyObject]]() = {"fruit":[{"name":"orange"},{"name":"apple"}],"flower":[{"name":"rose"}]}

Then you want to loop through the json result and grab out the values into the above format you want:

// Swift representation of your provided example let results = [["type":"fruit", "name":"orange"],["type":"flower","name":"rose"],["type":"fruit", "name":"apple"]] // Desired dictionary of key:array of dictionaries var updatedResult = [String:[[String:String]]]() for item in results { if let name = item["name"], type = item["type"] { if updatedResult.keys.contains(type) { updatedResult[type]!.append(["name":name]) } else { updatedResult[type] = [["name":name]] } } }

Multiple inheritance can be used if the language allows it. I don't know much about it however.

Otherwise, you can build a StockItemNode : GraphicNode from a StockItem:

class ItemNodeFactory { ... StockItemNode create(StockItem); ... }

You can transfer properties from StockItem into an instance of StockItemNode (set-get) which would completely decouple the two types. Or you can have StockItemNode wrap an instance of StockItem (composition).

Doing it the other way around (having NodeStockItem : StockItem and/or wrapping a GraphicNode in a StockItem) would result in a particular bad design because you don't want to hardwire a coupling to a specific presentation (GraphicNode) inside a domain/business/data entity (StockItem).

11872269 0 stuck building a 'cart management' system

I'm trying to build a database for video spots. The main page is a list of spots and you can check them and modify them. What i want to do is build a cart system, where the checked spots' id's are automatically added to the cart and stored as a cookie. That way the use can browse multiple pages while still having everything stay checked.

So far, I have a checkbox on every spot that when checked calls a function that adds the id of the checkbox to an array and stores it as a cookie.

I'm able to retrieve the cookie through jquery. What I need to do is while looping through the spots and printing them, is to check if that spot id is in the cookie, so I can set it as checked or not through php. Is this possible? Is there a better way to accomplish this?

Here is what i have so far.

$(document).ready(function(){ var checkedItems = []; $('.spotCheck').click(function(){ var currentID = this.id; checkedItems.push(currentID); updateCookie(); }); function updateCookie(){ $.cookie('itemList',checkedItems); } $('#mainContainer').click(function(){ $('#textInCenter').html($.cookie('itemList') ); }); });

Clicking the checkbox adds the ID to the array checkedItems, and click the mainContainer makes it visible so I can see which items are currently in the array. I can browse through pages and the cookies stay in the array (there's no way to remove them now but I'm not worried about that right now).

So how can I check the array to see if an id is in there when I print the list of spots?

22225288 0 Performance of $rootScope.$new vs. $scope.$new

My current Controllers $scope is kind of thick with: $watch and event handlers.

On one point I need to create a new scope for a modal, which does not have its own controller, because its quite simple. Still it needs a property of the current $scope. I was wondering which of the following solutions is better, and why?

var modalScope = $rootScope.$new(); modalScope.neededValue = $scope.neededValue;

var modalScope = $scope.$new(); // modalScope.neededValue already there

Should I be worried that the created modalScope will watch also those expressions and events? Any other aspects I should be aware of?

I prefer to keep them in a separate config file, located somewhere outside the web server's document root.

While this doesn't protect against an attacker subverting my code in such a way that it can be coerced into telling them the password, it does still have an advantage over putting the passwords directly into the code (or any other web-accessible file) in that it eliminates concern over a web server misconfiguration (or bug/exploit) allowing an attacker to download the password-containing file directly.

22260913 0 Is a real-time system sdhedulable?

There is a question in my operating systems book about scheduling a system.

The question is: A real-time system needs to handle two voice calls that each run every 5 msec and consumes 1 msec of CPU time per burst, plus one video at 25 frames/sec, with each frame requiring 20 msec of CPU time. Is the system schedulable?

The solution manual has this answer: Each voice call runs 200 times/second and uses up 1 msec per burst, so each voice call needs 200 msec per second or 400 msec for the two of them. The video runs 25 times a second and uses up 20 msec each time, for a total of 500 msec per second. Together they consume 900

The book does not explain how to come to this conclusion, or gives an algorithm. So I was hoping someone could explain how this answer is worked out?

Thank you.

For a project I did once, we used a ruby script to generate an AS file containing references to all classes in a certain package (ensuring that they were included in the compilation). It's really easy considering that flash only allows classes with the same name as the file it's in, so no parsing of actual code needed.

It would be trivial to also make that add an entry to a dictionary (or something similar), for a factory class to use later.

I believe it's possible to have a program execute before compilation (at least in flashdevelop), so it would not add any manual work.

Edit: I added a basic FlashDevelop project to demonstrate. It requires that you have ruby installed. http://dl.dropbox.com/u/340238/share/AutoGen.zip

To get just those records that ARE in Encounter and NOT in EnctrAPR, then just use left outer join instead of full outer join, and add a clause excluding null values for EnctrAPR.EncounterNumber.

i.e.

SELECT Encounter.EncounterNumber, substring(Encounter.EncounterNumber,4,9) as Acct, ... EnctrAPR.APRDRG, Age18, Age18To64, Age65 from Encounter left outer join EnctrAPR on substring(Encounter.EncounterNumber,4,9) = EnctrAPR.EncounterNumber where EnctrAPR.EncounterNumber is null and HSP# = 1 and InOutCode = 'I' and ActualTotalCharge >0 and AdmitSubService <> 'SIG' and [DischargeDate - CCYYMMDD] between @StartDate and @EndDate and Encounter.Age >= 18

Note though that the value for EnctrAPR.APRDRG will always be null, as EnctrAPR doesn't have a matching row.

Q_MONKEY_EXPORT is most likely a #define somewhere. Defines like that are sometimes required, for example when the class is in a library and needs to be exported when the header file is included from somewhere else. In that case, the define resolves to something like __declspec(dllexport) (the exact syntax will depend on the tools you are using).

If necessary, you may create your own class implement interface Map, and make it a delegator of its HashMap-typed field for customized management of key comparisons.(You may override equals() and hashCode() for keys.

Try this. I am sure you can do this via a couple JOINs (or at least part of it) but you did not request what your return columns should be

SELECT v.visitID FROM Visits AS v WHERE EXISTS(SELECT * FROM VisitDocs AS d WHERE d.VisitID = v.VisitID AND d.docType = 3) AND NOT EXISTS(SELECT * FROM VisitDocs AS d WHERE d.VisitID = v.VisitID AND d.docType Not IN (1,2))

34602213 0 iOS Facebook Authentication PhoneGap on TestFlight

I'm currently testing my app on my iPhone that I built using Phonegap's Adobe Build with Apple's TestFlight application. My app contains Facebook authentication and when I click the authentication button I am presented with the following error:

Given URL is not allowed by the Application configuration: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.

I did a bit of research online and I added the iOS Platform along with my Bundle ID in the respective field on facebook's developer panel but that did not appear to fix things.

31712185 0 How to get correct summaries with analytics?

I want to get summary numbers from the cust_detail table if a specific invoice_code appears in invoice_detail.

In this example, I'd like to report cust_detail summaries only for batches 10 and 20 because they are the ones with invoice_code='9999'. But the duplication in the invoice_detail table is skewing my numbers.

with invoice_detail as ( select '10' as invoice_batch, '9999' as invoice_code from dual union all select '10' as invoice_batch, '9999' as invoice_code from dual union all select '20' as invoice_batch, '1111' as invoice_code from dual union all select '30' as invoice_batch, '9999' as invoice_code from dual ), cust_detail as ( select '1' as cust_id, '10' as invoice_batch, 40 as points_paid, 30 as points_earned, 30 as points_delivered from dual union all select '1' as cust_id, '20' as invoice_batch, 10 as points_paid, 10 as points_earned, 10 as points_delivered from dual union all select '1' as cust_id, '30' as invoice_batch, 20 as points_paid, 15 as points_earned, 5 as points_delivered from dual ) select cust_id, sum(points_paid) over (partition by c.invoice_batch order by cust_id) batch_total from cust_detail c inner join invoice_detail i on c.invoice_batch=i.invoice_batch where i.invoice_code = '9999';

Desired results:

 CUST_ID PAID EARNED DELIVERED TOT_PAID TOT_EARNED TOT_DELIVERED --------- ------ -------- ----------- ---------- ------------ --------------- 1 40 30 30 60 45 40 1 20 15 5 60 45 40

You can use include_once or include at your index.php

Try this code for index.php :

Problem is presence of ! in your character class that is doing history expansion.

I suggest declaring your regex beforehand like this:

re="^[0-9][0-9a-zA-Z\!#$%^&/*'+-]+$"

Then use it as:

s='1/' [[ $s =~ $re ]] && echo "good" || echo "bad" good

I found the solution: Because I was using a auto generated pom.xml, I added the maven-s3-wagon extension to publish the library to a Maven repo on a AWS S3 server. So, the pom.xml file had other plugins for Maven. I think that mvn was calling both processes: the regular Maven deployment and the Maven S3 Wagon, and that would be the reason why the deployment process was doing an "extra step" and generating two names: artifact-id-xxxx.142230-1 and artifact-id-xxxx.142243-2

I removed all the plugins into <build> section and leave only the maven-s3-wagon extension. It worked like a charm.

<build> <extensions> <extension> <groupId>org.kuali.maven.wagons</groupId> <artifactId>maven-s3-wagon</artifactId> <version>1.2.1</version> </extension> </extensions> </build>

15215355 0 Consistently subset matrix to a vector and avoid colnames?

I would like to know if there is R syntax to extract a column from a matrix and always have no name attribute on the returned vector (I wish to rely on this behaviour).

My problem is the following inconsistency:

when a matrix has more than one row and I do myMatrix[, 1] I will get the first column of myMatrix with no name attribute. This is what I want.
when a matrix has exactly one row and I do myMatrix[, 1], I will get the first column of myMatrix but it has the first colname as its name.

I would like to be able to do myMatrix[, 1] and consistently get something with no name.

An example to demonstrate this:

# make a matrix with more than one row, x <- matrix(1:2, nrow=2) colnames(x) <- 'foo' # foo # [1,] 1 # [2,] 2 # extract first column. Note no 'foo' name is attached. x[, 1] # [1] 1 2 # now suppose x has just one row (and is a matrix) x <- x[1, , drop=F] # extract first column x[, 1] # foo # <-- we keep the name!! # 1

Now, the documentation for [ (?'[') mentions this behaviour, so it's not a bug or anything (although, why?! why this inconsistency?!):

A vector obtained by matrix indexing will be unnamed unless ‘x’ is one-dimensional when the row names (if any) will be indexed to provide names for the result.

My question is, is there a way to do x[, 1] such that the result is always unnamed, where x is a matrix?

Is my only hope unname(x[, 1]) or is there something analogous to ['s drop argument? Or is there an option I can set to say "always unname"? Some trick I can use (somehow override ['s behaviour when the extracted result is a vector?)

There are a number of ways to archive this. One easy way is to submit all data to the server, where the whole form gets rebuild. Doing this on javascript-side could be done with templating (I assume you use jquery).

The serverside-solution (as the final submitting) requires, that your input-names are formed wisly.

Example:

data[members][{$memberId}][name]

If you want to determine, if the form was submitted in its final form, or just to add a member, you can form the submit-buttons like this:

<input type="submit" name="btn[submit]" value="submit booking" /> <input type="submit" name="btn[add]" value="submit booking" />

On php-side this could be determined by:

$btnType = isset($_REQUEST['btn']) && is_array($_REQUEST['btn']) ? array_shift(array_keys($_REQUEST['btn'])) : 'submit';

There are still improvements to apply!

31565847 0 Multiplying one matrix with a set of scalars

I have an R script that systematically perform changes to a 3x3 matrix by scalar multiplication as follows

R <- matrix(rexp(9, rate=.1), ncol=3); for (i in 1:360) { K = i*R; ... }

and use the modified matrix for further calculations within the loop. However, the loop itself is nested inside two other for loops, making the script very slow. So my question is, how can I vectorize this innermost loop such that the result instead is a three-dimensional array A of size 3x3x360 where

A[,,i] = i*R;

for all i ranging from 1 to 360?

Since OS X 10.10, NSStatusItem has button property, which is a regular NSView-based control that conforms to NSAccessibility protocol and which allows to change accessibilityTitle property directly.

On earlier versions of OS X, you can implement a custom button that looks and behaves exactly like vanilla NSStatusItem and assign it to the item via -[NSStatusItem setView:] method, then use -[NSView accessibilitySetOverrideValue:... forAttribute:NSAccessibilityTitleAttribute] on your custom control to provide a voiceover title.

19140817 0 Rails - ajax page partial update

I have my home.html.haml page rendering 3 partials:

%h1 Foo #foo1 = render partial: 'foo/foo', locals: {items: @foo1_items} #foo2 = render partial: 'foo/foo', locals: {items: @foo2_items} #foo3 = render partial: 'foo/foo', locals: {items: @foo3_items}

Currently, I have some remote links that refresh these parts individually firing an ajax call to to the home page:

= link_to 'refresh', home_path(mode: 'foo1'), remote:true = link_to 'refresh', home_path(mode: 'foo2'), remote:true = link_to 'refresh', home_path(mode: 'foo3'), remote:true

and I have a home.js.erb that contains something like this:

<% if params[:mode] == 'foo1'%> $('#foo1').html('<%= j(render partial: 'foo/foo', locals: {items: @foo1_items}) %>') <% elsif params[:mode] == 'foo2'%> $('#foo2').html('<%= j(render partial: 'foo/foo', locals: {items: @foo2_items}) %>') <% else %> $('#foo3').html('<%= j(render partial: 'foo/foo', locals: {items: @foo3_items}) %>') <% end %>

I am wondering:

if this is the default(suggested, best) Rails way to do a partial page refresh or generally the way to handle ajax requests?
if it would be faster to have server respond with pure html and let the client (javascript) to do the replacing?
how do you handle this in your application?

I would say that the real reason is that try-with-resources isn't so much new JVM feature as it is a compile-time language feature. In this way, it is very much analogous to the "enhanced for statement" which requires a class that has implemented the Iterable interface (you have to name an instance of the implenting class there, too). Try-with-resources requires that the resource implements the AutoCloseable interface. It is not wrong to regard the block as "syntactic sugar, introduced in 1.7". It just prevents you from having to deal with calls to the interface method yourself.

Because the feature requires an object whose class has implemented the interface, you must give the try-with-resources block the name of that object.

Is there any way to get a response without the target namespace?

I hope not. A SOAP web service should have a well-defined, published interface and every response that it sends should conform to that interface. Usually, the interface is described by a WSDL document.

And would like to get it without the target namespace

<MyItem> <class>myClass</class> <name>MyItemName</name> </MyItem>

Being pedantic, but the absence of a namespace prefix does not mean that there is no namespace. There might be a default namespace in force. So you could achieve XML that looks exactly like the above and the MyItem, class and name tags might still have a non-empty namespace.

I know its purpose and that it's actually quite useful.

The purpose of a namespace in an XML document ( whether a web service response, or any other XML ) is to avoid polluting the global namespace. Do you really want 'name' and 'class' to have exactly one meaning in your applications? Or would it be better if each schema could define its own version of those?

But it happened that it can't be processed any further by another tool with this target namespace and looks like this:

<MyItem xmlns="http://spring.io/guides/gs-producing-web-service"> ...

That looks like valid XML, so what's the problem? Is that output produced by the 'other tool'? Or is it something that the 'other tool' cannot handle?

14380143 0 Matching binary patterns in C

I'm currently developing a C program that needs to parse some bespoke data structures, fortunately I know how they are structured, however I'm not sure of how to implement my parser in C.

Each of the structures are 32-bits in length, and each structure can be identified by it's binary signature.

As an example, there are two particular structures that I'm interested in, and they have the following binary patterns (x means either 0 or 1)

 0000-00xx-xxxx-xxx0 0000-10xx-10xx-xxx0

Within these structures the 'x' bits contain the actual data I need, so essentially I need a way of identifying each structure based on how the bits are written within each structure.

So as an example in pseudo-code:

if (binaryPattern = 000010xxxxxxxxx0) { do something with it; }

I'm guessing that reading them as ints, and then performing some kind of bitmasking would be the way to go, but my knowledge of C isn't great, and maybe a simple logical OR operation would do it, but I just wanted some advice on doing this before I start.

Thanks

Thanks very much to everyone that has answered, very helpful!!

The problem is because of this:

This is happening because your service has not stopped within your timeout. You should either set your timeout higher, or don't set a timeout at all.

Put this in a bat file (change the path to your tools directory, and yourappname is of course your app's name):

Then in your code just do something similar to this:

Log.d("yourappname", "Your message");

To create the log, connect the USB cable and run your bat file.

Without having to increase the asset size of your app, you could create a simple UIView.

UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow]; UIView *fullscreenShadow = [[UIView alloc] initWithFrame:keyWindow.bounds]; fullscreenShadow.backgroundColor = [UIColor blackColor]; fullscreenShadow.alpha = 0.3; [keyWindow addSubview:fullscreenShadow];

Adding it to the keyWindow will make it cover everything, except the UIStatusBar of course. I believe this will achieve your intended result. Combine it with a UIViewAnimation and bring the alpha up.

29311039 0 how can I select the other departments from this query

So I have the following query

SELECT deptno, COUNT(deptno) number_of_jobs FROM emp WHERE job = 'SALESMAN' GROUP BY deptno ORDER BY number_of_jobs ASC;

What this does is to return me just department 30, while I want departments 10 and 20 aswell.

Like this

deptno number_of_jobs 10 (here it can be null or 0 doesn't really matter) 20 (same like dept 10) 30 4

I know this is fairly easy and I believe it's done using a join condition, but I just can't get my head around it.

var myObject = new Array(); $selectedRows.each(function () { var record = $(this).data('record'); var id = record.id; var proyecto = record.proyecto; var tarea = record.tarea; var fase = record.fase; var name = record.name; var timeStart = record.timeStart; var timeEnd = record.timeEnd; var duracion = record.duracion; var facturada = record.facturada; var activa = record.deleted; var actividad = [{id:id,proyecto:proyecto, tarea:tarea,tarea:tarea,fase:fase,name:name,timeStart:timeStart,timeEnd:timeEnd,duracion:duracion,facturada:facturada,activa:activa }]; myObject.push(actividad); });

Chrome console sais that I created an Array that have Arrays that have each one its correlative object, something like: [Array[1], Array[1], Array[1] ... ] My objects are inside that arrays Can I convert it to:

[object, object, object...]

To skip lines that do not match those strings add a check:

if any(bool(x) for x in d, HD, HA, M): print ... output.write

Try running the script in a debugger:

$ python -m pdb your_script.py

and see what variables are there and what's wrong. Since PDB is not convenient, you might want to install ipdb or pudb.

Use UIDevice Macros - http://d3signerd.com/tag/uidevice/

Then you can write code like;

if ([DEVICE_TYPE isEqualToString:DEVICE_IPAD]) { }

if (IS_SIMULATOR && IS_RETINA) { }

You can change the log in the y axis with the following:

plt.gca().set_yscale('linear')

Or press the L key when the figure is in focus.

However, your hist() with log=True does not plot a logarithmic x axis. From the docs:

matplotlib.pyplot.hist(x, bins=10, ...)

bins: Either an integer number of bins or a sequence giving the bins. If bins is an integer, bins + 1 bin edges will be returned, consistent with numpy.histogram() for numpy version >= 1.3, and with the new = True argument in earlier versions. Unequally spaced bins are supported if bins is a sequence.

So if you just set bins=10 they will be equally spaced, which is why when you set the xscale to log they have decreasing widths. To get equally spaced bins in a log xscale you need something like:

plt.hist(x, bins=10**np.linspace(0, 1, 10))

I had a similar problem and the solution that I found was to replace the startActivityForResult functionality by storing the result into the shared preferences and loading them later in onResume. Check the full discussion here.

Maybe you are confused by the fact, that the class Ordering is declared as Ordering<T>, but the return value of the onResultOf method is Ordering<F>.

The first type argument of the Function, you are providing to onResultOf is the type argument of the result.

That also means, that Value is not forced to be a subtype of Map.Entry.

It doesn't matter how you pass the arguments to below,

while ((i = getopt_long(argc, argv, "MCFA:acdegphinNorstuVv?wxl", longopts, &lop)) != EOF) switch (i) { ... case 'a': flag_all++; break; case 'n': flag_not |= FLAG_NUM; break; ...

Just the cases a & n are enabled which is processed later with the respective flags set.

You cannot find socat libraries because there are none. socat is implemented as a monolithic executable (it does link to the standard system libraries though). You can download socat sources and copy-paste required functionality.

Give your text box a id for example "txtInput" give your iframe a id for example "myIframe" on the button give it no navigation so it stays on current page and use the onclick="myFunction()"

in the function you can use this (excuse me if this is slightly wrong its been a while since I have used HTML

 function myFunction() { var iframe = document.getElementById("myIframe"); var input = document.getElementById("txtInput").text; //check to see if there is a valid url in the text box be carefull if there are multiple links in the text box it will put them all in and the iframe will go to 127.0.0.1 or search engine due to incorrect URL var isURL=new RegExp(/(((f|ht)(tp|tps):\/\/)[\w\d\S]+)/,g); iframe.src = input.match(isURL); }

If you do not want to mess with regular expresions you can just simply use the following.

function myFunction() { var iframe = document.getElementById("myIframe"); var input = document.getElementById("txtInput").text; iframe.src = isURL; }

As per you are not using AsyncTask, you can't get the opportunity of onProgressUpdate feature. So, you have to update your progress bar status manually like using own thread and you have already do. But, I solved my problem using below source code, you can check it:

 private void createThread(){ Runnable runable = new updateProgressStatus(); progressUpdateThread = new Thread(runnable); progressUpdateThread.start(); } public class updateProgressStatus implements Runnable { public void run() { while(Thread.currentThread()==progressUpdateThread) try { Thread.sleep(1000); progressHandler.sendMessage(YOUR MESSAGE ); } catch (InterruptedException e) { // Interrupt problem Thread.currentThread().interrupt(); } catch (Exception e) { e.printStackTrace(); } } } private Handler progressHandler = new Handler(){ @Override public void handleMessage(Message message) { // Now, update your progress bar status progress.setProgress(message.what); } };

11655044 0 Lazy list items are not clicking per item only per row

I have been breaking my head trying to get this working but I can't to save my life, I was hoping one of you guys knew how to do it. Basically, I have a list of nature pictures that are loading in a lazy ListView, but my problem is that I can only make the row clickable. I need to make the the individual images clickable. Everything else works like a charm, I really appreciate the help.

There is no problem in your code, but the problem in client request, because Content-Type should be like below if you want to upload image,

multipart/form-data; boundary="123123"

try to remove the Content-Type header and test, i will put one example for server code and client request

Server code:

@RequestMapping(method = RequestMethod.POST, value = "/users/profile") public ResponseEntity<?> handleFileUpload(@RequestParam("name") String name, @RequestParam(name="file", required=false) MultipartFile file) { log.info(" name : {}", name); if(file!=null) { log.info("image : {}", file.getOriginalFilename()); log.info("image content type : {}", file.getContentType()); } return new ResponseEntity<String>("Uploaded",HttpStatus.OK); }

Client Request using Postman

with image

without image

Curl example:

without image, with Content-Type

curl -X POST -H "Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW" -F "name=test" "http://localhost:8080/api/users/profile"

without image, without Content-Type

curl -X POST -F "name=test" "http://localhost:8080/api/users/profile"

Two potential sources of the problem, you shouldn't store your files with spaces in their names and you haven't specified a type for your video.

The SRC should contain a valid URL and therefore you should have %20 or + in your PHP string in stead of the spaces.

Note: As mentioned by Fisk, your php tags are wrong due to the spacing. You use the PHP echo short-form by replacing

< ?php echo $vid; ? > by <?= $vid; ?>

8946877 0 grails not using cache

I've noticed a slow down on my site and after turning on debug 'org.hibernate.SQL' I see where the troubles are. I've set a domain class to be cached using....

class Foo{ ... static mapping ={ cache 'read-only' } String name //<-- simple data type, no associations String description //<-- simple data type, no associations }

My hibernate config looks like this...

hibernate { cache.use_second_level_cache=true cache.use_query_cache=true cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider' }

my query looks like this (in a web flow)...

def wizardFlow = { ... def flow.foos = Foo.list([sort:"name", order:"asc", cache:true]) // def flow.foos = Foo.findAll([cache:true]) <--- same result, no caching }

I would think that either the query cache or second level cache would stop the database from being hit but my log is loaded with...

select ... from thing thing0_ where thing0_.id=? select ... from thing thing0_ where thing0_.id=? select ... from thing thing0_ where thing0_.id=? select ... from thing thing0_ where thing0_.id=?

Can anyone shed some light on what might be happening? Other queries are acting as they should!

If your button is inside an UpdatePanel, you should place your BulletedList control inside an UpdatePanel too.

You can place an UpdatePanel surrounding the BulletedList in the MasterPage file. Set "UpdateMode" to "Conditional" then call the Update method of the UpdatePanel to refresh only when needed ('save button' click for example).

I've also had great success using Aptana's Jaxer + jQuery to parse pages. It's not as fast or 'script-like' in nature, but jQuery selectors + real JavaScript/DOM is a lifesaver on more complicated (or malformed) pages.

I suggest that you use child_process.spawnSync which is a blocking call and returns ONLY after the process is complete. In addition, the object returned includes an error property that contains the code.

But in all cases - spawn or spawnSync, etc, I believe the result object always includes an error object if the sub-process fails for any reason. So checking for the existence of this object is probably enough.

This should work (without a double replace):

<? echo preg_replace("#(http|ftp|https):/([^/])#", "$1://$2", 'http://www.google.com'); echo "<br>"; echo preg_replace("#(http|ftp|https):/([^/])#", "$1://$2", 'http:/www.google.com'); ?>

This will only do the replace if there is no double slash.

String * means a pointer to a String, if you want to do anything with the String itself you have to dereference it with *moj. What you can do instead is this:

String moj = String("Alice has a cat"); // note lack of * and new cout << moj[2];

Also note that anything you allocate with new needs to be deleted after:

String *x = new String("foo"); // code delete x;

It sounds like you were trying to used nested loops, but you in fact had one loop at the beginning which closed out and then you loop through the rest. You need to move your closing curly brace marked below:

for($i=0; $i<count($_FILES['upload']['name']); $i++) { $filut = basename($_FILES['upload']['name'][$i]); } <<<<<<<<<=========== This curly brace closes the "for loop" if(isset($_POST['subi'])) { $data1 = $_POST['answers']; foreach($data1) as $postValues) { $sql4 = 'INSERT INTO db_image (text, image) VALUES("'.$postValues.'","'.$filut.'")'; $my->query($sql4); } } ??? <<<<<======== For a nested loop you should close it here

or perhaps you were trying to assign $filut as an array in which case the starting for... loop needs to look like this:

for($i=0; $i<count($_FILES['upload']['name']); $i++) { $filut[] = basename($_FILES['upload']['name'][$i]); }

(Note the addition of [] after $filut.)

However, if this is what you were intending (to make $filut into an array) then you need to do something different down below in order to access just one element of the array. This is where a nested foreach would solve the problem - maybe this is how you intended to finish it off:

if(isset($_POST['subi'])) { $data1 = $_POST['answers']; foreach($data1 as $postValues) { foreach ($filut as $f) { $sql4 = 'INSERT INTO db_image (text, image) VALUES("'.$postValues.'","'.$f.'")'; $my->query($sql4); } } }

This will insert a row for every value in $filut for every value in $_POST['answers']. Is that what you wanted? Or are $filut and $_POST['answers'] in parallel and you want a 1-1 correlation on the insert?

Finally I'm going to suggest that you use prepare and bind since you are getting your data from the user. This example copied/modified from here:

<?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } /* Prepare an insert statement */ $query = "INSERT INTO db_image (text, image) VALUES (?,?)"; $stmt = $my->prepare($query); #### NOTE THE USE OF YOUR VARIABLES HERE IN THE BIND - the "ss" means they are strings $stmt->bind_param("ss", $postValues, $f); #### HERE IS WHERE YOUR CODE IS GETTING INSERTED foreach($data1 as $postValues) { foreach ($filut as $f) { /* Execute the statement */ $stmt->execute(); } } /* close statement */ $stmt->close(); /* close connection */ $my->close(); ?>

I can't guarantee that I got all the variables changed to match your code, but hopefully it's close enough to give you an idea. This solution (1) protects you from SQL Injection (which is a serious flaw in your code otherwise) and (2) will be much faster by means of the prepare/execute cycle.

Do note the careful indentation in my examples where everything lines up perfectly with 3 or more spaces per indent - I can't tell you how many times I have seen sloppy (or too little) indentation make people miss problems which would be otherwise obvious.

Not sure if it's causing the problem, but head and body should be inside the html tag.

!!! = surround '<!--[if !IE]> -->'.html_safe, '<!-- <![endif]-->'.html_safe do %html.no-js{:lang => 'en'} %head %body

Could be confusing the surround method by having multiple tags appended instead of nested... Worth a try!

As I see it, you ned to verify two things for that builder:

the correct instance is returned
values, that are injected are the right ones.

Checking instance is the easy part. Verifying values needs a bit of trickery.

The simples way to do this would be altering the autoloader. You need to make sure that when MyClass is requested for autoloader to fetch, instead of /src/app/myclass.php file it loads /test/app/myclass.php, which actually contains a "transparent" mock (where you with simple getters can verify the values).

bad idea

Update:

Also, if you do not want to mess with autoloader, you can just at th top of your myBuilderTest.php file include the mock class file, which contains definition for MyClass.

... this actually seems like a cleaner way.

namespace Foo\Bar; use PHPUnit_Framework_TestCase; require TEST_ROOT . '/mocks/myclass.php' class MyBuilderTest extends PHPUnit_Framework_TestCase { public function MyBuilder_verify_injected_params_test() { $target = new MyBuilder; $instance = $target->build('a', 'b'); $this->assertEquals('a', $instance->getFirstConstructorParam(); } }

In PHP 5.6+ you could do something like this:

function foo(Abc ...$args) { } foo(...$arr);

foo() takes a variable amount of arguments of type Abc, and by calling foo(...$arr) you unpack $arr into a list of arguments. If $arr contains anything other than instances of Abc an error will be thrown.

This is a little 'hacky', but it's the only way to get type hinting for an array in PHP, without putting down some extra code.

17090094 0 LINQ Left Outer Join with conditions

I have the below tables that are coming from my SQL Database with Entity Framework 5.

What I want to do is select all users where tblUserBusiness.BUID equals a passed in value OR where the Users.IsSysAdmin equals True. If the Users.IsSysAdmin equals True there will be no relating tblUserBusiness records hence the Left Outer Join.

enter image description here

I started with the below LINQ query that filtered correctly but did not allow for the Outer Join

 businessUsers = (From u In db.Users From bu In db.tblUserBusinesses Where bu.BUID.Equals(buID) Or u.IsSysAdmin.Equals(True) Select New Users With {.ID = u.ID, .Name = u.Name, .UserName = u.UserName}).ToList

Then I moved onto the below query which allows for the Outer Join but I have no idea how to implement the Where bu.BUID.Equals(buID) Or u.IsSysAdmin.Equals(True)

 businessUsers = (From u In db.Users Group Join bu In db.tblUserBusinesses On u Equals bu.User Into userList = Group Select New Users With {.ID = u.ID, .Name = u.Name, .UserName = u.UserName}).ToList

Basically what I am after is the LINQ equivalent to the below TSQL

SELECT Users.ID, Users.UserName, Users.Name FROM Users LEFT OUTER JOIN tblUserBusiness ON Users.ID = tblUserBusiness.UserID WHERE (Users.IsSysAdmin = 1) OR (tblUserBusiness.BUID = 5)

The Hough Transform is the most commonly used algorithm to find lines in an image. Once you run the transform and find lines, it's just a matter of sorting them by length and then crawling along the lines to check for the constraints your application might have.

RANSAC is also a very quick and reliable solution for finding lines once you have the edge image.

Both these algorithms are fairly easy to implement on your own if you don't want to use an external library.

36069145 0 How to be sure that files are saved in gallery for all Android devices?

According to user reviews, my app dosn't save on their phones (LG4, oneplus phones, android 5.1, Android 6.0)

For Android 6.0 I have solved the problem by using the new permission system. But how can I be sure that the code actually works 100% on all devices? Is there any improvment that can be made?

This is the onClick method that is run, when the user clicks the save button But also ask for permission for Android 6 devices

public void saveQuote(View v) { if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) { //check if we have permissoin to WRITE_EXTERNAL_STORAGE if (PackageManager.PERMISSION_GRANTED == ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) { //This method just create a bitmap of my edittext saveBitmap(); } else { //if permission is not granted, then we ask for it ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_WRITE_EXTERNAL_STORAGE); } } }

This is the code that makes the saving operation:

private void saveImageToExternalStorage(Bitmap finalBitmap) { String filename = "#" + pref_fileID.getInt(SAVE_ID, 0) + " Quote.JPEG"; //The directory in the gallery where the bitmaps are saved File myDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString() + "/QuoteCreator"); //The directory in the gallery where the bitmaps are saved File myDir = new File(root + "/QuoteCreator"); //creates the directory myDir. myDir.mkdirs(); File file = new File(myDir, filename); try { FileOutputStream out = new FileOutputStream(file); finalBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out); out.flush(); out.close(); Toast.makeText(getApplicationContext(), R.string.savedToast, Toast.LENGTH_LONG).show(); } catch (Exception e) { e.printStackTrace(); } /* Tell the media scanner about the new file so that it is immediately available to the user. */ MediaScannerConnection.scanFile(this, new String[]{file.toString()}, null, new MediaScannerConnection.OnScanCompletedListener() { public void onScanCompleted(String path, Uri uri) { Log.i("ExternalStorage", "Scanned " + path + ":"); Log.i("ExternalStorage", "-> uri=" + uri); } }); }

You have two problems in getting your DIVIDE to work.

In order of occurrence:

You ACCEPT your AMOUNT. Your AMOUNT has an implied decimal place (the V in the PICture string), yet ACCEPT is going to, for your purpose, ignore this implied decimal. There will be no alignment with what the user types at the screen. There is more than one way to deal with this, perhaps the simplest for your purpose it to look at the Intrinsic FUNCTION NUMVAL.

You, as @Magoo indicated, do not use decimal points in your literals, so they are treated as whole numbers, so effectively the figures you expect to be used for the currency conversion are multiplied by 10,000 and left-truncated.

When reporting a problem it is a good idea to show the input data which gave you the problem, the result you actually achieved, and the expected result. If you can work out what is happening but are unsure how to correct it, that is a bonus.

You have tagged Coding-Style. I think you might want to remove that by editing your question. The people interested in the Coding-Style tag are probably not too aware of COBOL. If you have a future Career as a COBOL programmer, your style is going to be more or less dictated by the site standards of where you work, and will change from site to site. You can, of course, develop your own style, but it develops, it isn't just given to you. Knowing the messes you can get into helps you develop style (technique) in avoiding getting there. You'll still need to know how things happen, because not all programmers take the time to develop anything in the way of style.

Read through some of the questions here, and see if you get some ideas about common problems.

I think you are confusing assigning variables with aliases. assigning a variable means you store the result of the command in a variable what this command does

b=`pwd`

is running pwd and stores the answer in a variable b.

and alias means giving some command a different name. so running alias b pwd will make it so whenever you run b, you will actually run pwd

Yes, this is correct. In your example %PATH% will be expanded to the current value of the PATH variable, so this command is effectively adding a new entry to the beginning of the PATH.

Note that calling set PATH will only affect the current shell. If you want to make this change permanent for all shells, the simplest option is to set it as a user variable using the Environment Variables dialog box.

On Windows 8 you can open this dialog by hitting Win+s and searching for 'environment variables'. On earlier versions of Windows you can right-click 'My Computer', choose Properties, then Advanced system settings, then Environment variables. You can create (or update) a PATH variable in the user variables section and add whatever entries you need. These will be appended to the existing system path. If you take this approach you will need to open a new cmd shell after updating the variables.

This error message was introduced with SubGit version 3.2.1 and SVN Mirror add-on version 3.3.0.

SubGit/SVN Mirror rejects push operation that would result into branch replacement in Subversion repository. There are basically two cases when Git changes may lead to replacements on SVN side:

Force push.

When one forcefully pushes non-fast-forward update, SubGit/SVN Mirror has nothing to do but delete current version of the branch and re-create it from some older revision, because this is exactly what non-fast-forward update does: continuing branch history from a commit other than the branch tip.
Fast-forward merge from one branch into another.

When one creates a new branch foo from master:
```
$ git checkout -b foo $ git commit -am 'fix foo' [foo ca3caf9] fix foo 
```
then pushes that branch to SubGit mirror:
```
$ git push origin foo ... Sending commits to SVN repository: remote: ca3caf9 => r10 branches/foo 
```
which gets ca3caf9 mapped to branches/foo@10.

Finally, one merges branch foo back to master:
```
$ git checkout master $ git merge foo Updating 0e39ad2..ca3caf9 Fast-forward 
```
Noticed that Updating ... Fast-forward message? It means git merge found no new commits on master, hence there was no need to create a merge commit, i.e. git merge just moved the master pointer from older commit 0e39ad2 to a newer one ca3caf9.

Now what happens when one pushes master to SubGit mirror:
```
$ git push origin master 
```
SubGit finds out that master was updated from 0e39ad2 mapped to trunk@9 to ca3caf9 mapped to branches/foo@10. There's nothing SubGit can do but delete trunk and re-create it from branches/foo@10 which obviously leads to replacement of trunk.

And so we made sure that SubGit does not replace branches in these two scenarios unless SubGit administrator explicitly sets the following configuration option:

$ edit REPO/subgit/config ... [svn] allowBranchReplacement = true ... $ subgit install REPO

However, I'd recommend to keep svn.allowBranchReplacement set to false and follow these best practices to avoid the error message reported in the original question:

Never force push anything; prefer to merge, revert of branch out changes rather than overwrite them.
When merging one branch into another add --no-ff option: it forces git merge to create a merge commit when it would rather do a fast-forward update otherwise:
```
$ git merge --no-ff foo 
```

29424477 0 How do I make a hotkey to activate a specific VMware Workstation VM?

I'm using the latest version of VMware Workstation (11.1.0) on Windows 7 x64 and I want to be able to do a keystroke of "Ctrl + 1" to go to VM #1, "Ctrl + 2" to go to VM #2, and "Ctrl + 3" to go to VM #3.

Sounds simple right? It isn't.

On Mac OS X, achieving this functionality is trivial with VMware Fusion in combination with Spaces / Mission Control - you can simply put each VM on a separate space and then define whatever space hotkeys you want. I'm migrating from OS X and want this same functionality.

For reference, here are some potential solutions that I've tried and can verify that they don't work:

1) AutoHotkey

AutoHotkey can be used to make hotkeys like so:

^1::WinActivate, Win7(1) - VMware Workstation ^2::WinActivate, Win7(2) - VMware Workstation ^3::WinActivate, Win7(3) - VMware Workstation

These work to enter the VMs, but not to exit; Workstation will feed the "Ctrl + 1" to the VM and AutoHotkey does not take precedence, even if AutoHotkey is run as an administrator.

2) Suspend/Unsuspend with AutoHotkey

This promising post suggests that suspending and that unsuspending AutoHotkey while the VMware window is active will fix the problem:

http://superuser.com/questions/232762/autohotkey-script-to-exit-vmware-window

However, even after copying the exact code and making the necessary string modifications, I can't get it to work with Workstation.

3) Remote Desktop and/or VNC

One possible solution, if all 3 of the VMs in question were running Windows, would be to use Microsoft's Remote Desktop feature. However, one or more of the VMs that I intend to use will be running Linux.

On Linux, it is possible to just use VNC. However, VNC has considerable drawbacks when compared to the native VMware Workstation console window: there is no sound, the resolution won't automatically scale, the performance will be bad, and so forth.

Lastly, the VMs will be on 1) networks that won't be connected to the host via a bridged NIC (with the NIC disabled on the host) and 2) using a VPN without any split tunnel. So there will be no connectivity for either remote desktop or VNC in the first place.

3) A Windows Keyboard Hook

Liuk explains how to use a Windows hook to intercept keystrokes using C++:

http://polytimenerd.blogspot.com/2011/02/intercepting-keystrokes-in-any.html

However, after testing with the demo program, it seems that this method does not intercept keystrokes sent to VMware Workstation.

4) FullScreenSwitch.directKey

It seems that in VMware Workstation used to have this kind of functionality built in, as documented in this SuperUser thread:

http://superuser.com/questions/71901/vmware-workstation-keyboard-shortcut

However, VMware's documentations states that this is for VMware Workstation 5.0. I tried adding these strings to my VMX file and they had no effect, so the functionality must have been depreciated somewhere along the lines between Workstation 5 and 11.

5) PSExec

Wade Hatler mentions that he accomplishes this using PSExec to activate the appropriate AutoHotkey script on the host machine:

http://www.autohotkey.com/board/topic/64359-sending-keystrokes-to-vmware-player/

This solution is questionable in that you have to keep the password of your host machine in plaintext in order to pass it to PSExec.

Regardless, this solution will not work for the reasons also described in #2 above: the VMs in question will be on 1) networks that won't be connected to the host via a bridged NIC (with the NIC disabled on the host) and 2) using a VPN without any split tunnel. So there will not be guaranteed connectivity between the host and the guest.

6) Execute a "Host" keystroke between every "Ctrl + #" keystroke

This is problematic in that it doubles the amount of keystrokes involved and makes it impossible to "flip" through all of my VMs by holding down control and hitting 1 + 2 + 3 + 4 + 5, and so forth.

7) Use the "Host + Left/Right Arrow" hotkey and/or VMware-KVM.exe for cycling functionality

This is problematic in that when I have 10 or more VMs open at a time, rotating through all of them becomes incredibly cumbersome and inefficient.

Yes there are plugins that offers this functionality, I think most of the drag and drop jQuery plugins has their own callback function that triggers once the dragging and dropping has finished. jQuery List DragSort is a plugin I've used in my project before, it's lightweight and easy to use.

$("menu").dragsort({dragEnd: showHiddenCells }); function showHiddenCells() { //triggers after the user drops the element }

Since you've posted no logcat, I can't correct your code, but I can give you a working example:

I've looked at the MSDN page... it said NtQuerySystemInformation() is an OS internal proc, and that we're not recommended to use it:

The NtQuerySystemInformation function and the structures that it returns are internal to the operating system and subject to change from one release of Windows to another. To maintain the compatibility of your application, it is better to use the alternate functions previously mentioned instead.

The problem is exactly what the Traceback log says: Could not convert string to float

If you have a string with only numbers, python's smart enough to do what you're trying and converts the string to a float.
If you have a string with non-numerical characters, the conversion will fail and give you the error that you were having.

The way most people would approach this problem is with a try/except (see here), or using the isdigit() function (see here).

Try/Except

try: miles = float(input("How many miles can you walk?: ")) except: print("Please type in a number!")

Isdigit()

miles = input("How many miles can you walk?: ") if not miles.isdigit(): print("Please type a number!")

Note that the latter will still return false if there are decimal points in the string

EDIT

Okay, I won't be able to get back to you for a while, so I'll post the answer just in case.

while True: try: miles = float(input("How many miles can you walk?: ")) break except: print("Please type in a number!") #All of the ifs and stuff

The code's really simple:

It will keep trying to convert the input to a float, looping back to the beginning if it fails.
When eventually it succeeds, it'll break from the loop and go to the code you put lower down.

The only side effect to keep using .NET 2.0 is that you will not have access to features of newer .NET, such as LINQ, Task Parallel Library, etc.

See this Wikipedia Article for a full comparison of framework features by version.

Windows 7 already comes with .NET 3.5 built in, so if that is really the earliest OS you intend to target, there is really no need to taget .NET 2.0.

If you target .NET 3.5, Windows 7 users can run it with no prerequisite to install .NET 4.0 or higher, but Windows 8 users will need to enable .NET 3.5 (see Scott Chamberlain's answer). So either way, there is a tradeoff.

Based on Walker Hale IV's answer to a similar (but distinct! ;) ) question, there are two keys to doing this:

you don't need to install distribute and pip because these are automatically included in a new virtual environment (and you presumably only want the versions that have been tested with virtualenv)
you can use the virtualenv source code to create a new virtual environment, rather than using the system-installed version of virtualenv

So the workflow is:

install Python version X on your system
download virtualenv source code version Q (probably the latest)
create new virtual environment with Python X and virtualenv Q
your new VE is now running Python X and the latest stable versions of pip and distribute
pip install any other packages
easy_install any other packages that you can't pip install

Notes:

In your new virtual environment, you could install new (or old) versions of distribute, pip or virtualenv. (I think)
I don't use WH4's technique of create a bootstrap virtual environment. Instead, I create the new virtual environment from the virtualenv source each time.
This technique should be usable on any operating system.
If I were explaining this to someone new to the whole Distribute/pip/virtualenv ecosystem concept, I would explain it in a virtualenv-centric way.

I've written a bash script that does the basics in Ubuntu:

 #! /bin/bash # Script to create a python virtual environment # independently of the system version of virtualenv # # Ideally this would be a cross-platform Python # script with more validation and fewer TODOs, # but you know how it is. # = PARAMETERS = # $1 is the python executable to use # examples: python, python2.6, /path/to/python # $2 is the new environment folder # example: /path/to/env_folder/name ## TODO: should be just a name ## but I can't concatenate strings in bash # $3 is a pip requirements file # example: /path/to/req_folder/name.txt # you must uncomment the relevant code below to use $3 ## TODO: should be just a name ## but I can't concatenate strings in bash # other parameters are hard-coded below # and you must change them before first use # = EXAMPLES OF USE = # . env_create python2.5 /home/env/legacy ## creates environment "legacy" using python 2.5 # . env_create python /home/env/default ## creates environment "default" using whatever version of python is installed # . env_create python3.2 /home/env/bleeding /home/req/testing.txt ## creates environment "bleeding" using python 3.2 and installs packages from testing.txt using pip # = SET UP VARIABLES = # Required version of virtualenv package VERSION=1.6.4 # Folder to store your virtual environments VE_FOLDER='/media/work/environments' ## TODO: not used because I can't concatenate strings in bash # Folder to store bootstrap (source) versions of virtualenv BOOTSTRAP_FOLDER='/media/work/environments/bootstrap' ## TODO: not used because I can't concatenate strings in bash # Folder to store pip requirements files REQUIREMENTS_FOLDER='/media/work/environments/requirements' ## TODO: not used because I can't concatenate strings in bash # Base URL for downloading virtualenv source URL_BASE=http://pypi.python.org/packages/source/v/virtualenv # Universal environment options ENV_OPTS='--no-site-packages --distribute' # $1 is the python interpreter PYTHON=$1 # $2 is the target folder of the new virtual environment VE_TARGET=$2 # $3 is the pip requirements file REQ_TARGET=$3 ## = DOWNLOAD VIRTUALENV SOURCE = ## I work offline so I already have this downloaded ## and I leave this bit commented out # cd $BOOTSTRAP_DIR # curl -O $URL_BASE/virtualenv-$VERSION.tar.gz ## or use wget # = CREATE NEW ENV USING VIRTUALENV SOURCE = cd $BOOTSTRAP_FOLDER tar xzf virtualenv-$VERSION.tar.gz # Create the environment $PYTHON virtualenv-$VERSION/virtualenv.py $ENV_OPTS $VE_TARGET # Don't need extracted version anymore rm -rf virtualenv-$VERSION # Activate new environment cd $VE_TARGET . bin/activate # = INSTALL A PIP REQUIREMENTS FILE = ## uncomment this if you want to automatically install a file # pip install -r $REQ_TARGET # = REPORT ON THE NEW ENVIRONMENT = python --version pip freeze # deactivate ## uncomment this if you don't want to start in your environment immediately

13961384 0 requestNextPage() not a function in Backbone.Paginate

I am writing a backbone collection which requires pagination. So this is my code

define([ 'underscore', 'backbone', 'models/object', 'backbone_paginate' ], function(_, Backbone, Object){ "use strict"; var myCollection= Backbone.Paginator.clientPager.extend({ model: Object, paginator_core: { // the type of the request (GET by default) type: 'GET', // the type of reply (jsonp by default) dataType: 'json', // the URL (or base URL) for the service url: location.protocol + '//' + location.host+'/address' }, paginator_ui: { // the lowest page index your API allows to be accessed firstPage: 1, // which page should the paginator start from // (also, the actual page the paginator is on) currentPage: 1, // how many items per page should be shown perPage: 3, // a default number of total pages to query in case the API or // service you are using does not support providing the total // number of pages for us. // 10 as a default in case your service doesn't return the total totalPages: 10, pagesInRange: 3 }, server_api: { '$top': function() { return this.totalPages * this.perPage; }, }, parse:function(dat){ return dat.items; } }); return new myCollection(); });

My view looks like this:

define([ 'jquery', 'underscore', 'backbone', 'collections/addressLists', 'models/object', 'views/shared_object_item', ], function($, _, Backbone, AddressLists,Address,Shared_object_item){ "use strict"; var AppView = Backbone.View.extend({ events: { }, initialize: function() { _.bindAll(this,'render','updateData','showMoreData','showAllData'); this.collection=AddressLists; this.collection.bind('reset',this.render); this.collection.fetch(); }, el:$('div')[0], render: function() { var that=this; $('.innerContainer').bind('scroll',function(){ if($(this)[0].scrollHeight-$(this).scrollTop()==$(this).outerHeight()){ that.showMoreData(); } }); this.updateData(); }, updateData:function(){ var that=this,collection; $('.innerItem').empty(); _.each(this.collection.models,function(model){ $('.innerItem').append(new Shared_object_item({parent:that,collection:that.collection,model:model}).render().el); }); }, showMoreData:function(){ this.collection.requestNextPage(); }, }); return AppView; });

now in my view I am calling : fetch();

and on success of the fetch I am trying to call this.collection.requestNextPage();

It works fine till fetch(), but as soon as it hits the requestNextPage function(which resides in the showMoreData() function ), it throws an error stating that requestNextPage() is not a function.

I dont know wheere am I going wrong here..

23088033 0 Logging response and request to OAuth provider

Is there a way to capture the response from requests served by OAuth? Specifically, I need to log the request and response from OAuthAuthorizationServerProvider.GrantResourceOwnerCredentials().

I've tried extending OwinMiddleware and overriding Invoke as shown in this post, but I'm unable to read the response body. I'd like to use a message handler as this post demonstrates, but I don't have UseHttpMessageHandler on my AppBuilder object.

Any help would be greatly appreciated. Thank you!

Update

Modifying the example provided in Brock's excellent video, here's what I need to do:

public class Startup { public void Configuration(IAppBuilder app) { app.Use(typeof(MW1)); app.Map("/api", fooApp => { fooApp.Use<MW2>(); }); } } public class MW1 { Func<IDictionary<string, object>, Task> next; public MW1(Func<IDictionary<string, object>, Task> next) { this.next = next; } public async Task Invoke(IDictionary<string, object> env) { var ctx = new OwinContext(env); await next(env); // I need to be able to read: <h1>MW2 called</h1> written by MW2 var body = ctx.Response.Body; // body.CanRead = False } } public class MW2 { Func<IDictionary<string, object>, Task> next; public MW2(Func<IDictionary<string, object>, Task> next) { this.next = next; } public async Task Invoke(IDictionary<string, object> env) { var ctx = new OwinContext(env); await ctx.Response.WriteAsync("<h1>MW2 called</h1>"); await next(env); } }

I actually need to read the response sent from the OAuth provider, but I assume it would be the same process.

The initial problem stems from the restriction that contracts cannot modify the object they belong to (otherwise, the program might behave differently in debug and release mode). The way the language enforces that restriction is by making the this pointer const.

A const this means is that you can't modify the this object's fields, and as for calling methods - those methods themselves must be annotated as const, and the same restrictions apply to the code of those methods. This explains the first error: the contract, which was const, was trying to call a non-const (mutable) method. Since mutable methods are allowed to modify this, and contracts are forbidden to do so, the compiler forbids the call.

Because of the transitive nature of D's constness, everything that's accessed through the this pointer becomes const. And, if any of the class fields are reference types, the target of their indirections becomes const too. This is how the type system will forbid modifying anything that can be reached through the this pointer.

The implication of this is that if a const method is trying to return a class field (with indirections, such as a class type like Node), the returned type must also be const. This is the source of the second error message: the return expression attempted to convert the const Node value, obtained through the const this, to a mutable Node. Currently, the syntax @property const Node sub() indicates that the method itself is const (and has as const this), not the return type.

Now, generally, in C++, an object with proper constness support will usually have multiple overloads for the methods which return a class field: const, and non-const. The const versions will return a const reference; the non-const will return a non-const reference. The two versions are needed to allow obtaining a mutable field reference when we have access to a mutable object, but still allow getting a const reference if we only have const access to the object. Most of the time, the code of the two methods will be identical - only the function signature will differ.

This is where D's inout comes in. Specifying it on the method and some of its arguments or return value means that those arguments or return value will have the same constness as that of this (the object being referred to). This avoids code duplication for the simple cases where returning const and mutable values uses the same code.

The syntax I used is @property inout(Node) sub() inout. I think it can be written in more than one way, but this syntax is unambiguous. Here, the parens in inout(Node) make it explicit that we apply the attribute on the return value, and not the function, and placing the method (this) inout attribute after the parameter list, like const in C++, unambigously specifies that it applies to the function itself.

First things first, the CoffeeScript compiler already has a join command:

-j, --join [FILE] 
Before compiling, concatenate all scripts together in the order they were passed, and write them into the specified file. Useful for building large projects.

Secondly, instead of using $(document).ready(function () { ...} ), you can just pass the function directly to the $() - $(function () { ... });

For your actual problem, there are a few ways you could do it.

Option 1:

Compile the .coffee files using the -b / --bare option, and then manually concatenate a file containing $(function() { and the start and }); at the end (but that's pretty gross).

Options 2:

Use something like exports = window ? this to get the global object, and assign the functionality you wish to run in the jQuery load function to that global object, eg:

FooModule = do -> class Foo constructor: (@blah) -> init = -> blah = new Foo('bar') init: init exports = window ? this exports.Foo = FooModule

You could then have another file that contains something like the following:

$(-> Foo.init() )

Hope one of those options is good?

17020545 0 Doctrine 2 Postgresql stock procedure mapping

i 'd like to associate to a doctrine entity a postgresql stock procedure (which returns a table as result) instead of a table

Ex : the procedure Get_Uuser(sexe, age) search all the users for the selected parameters et returns a collection of user_id (names user_id_rech for exemple).

In pgsql, I can use this stock procedure as a table :

select user_name from User left join Get_User('H', 45) where User.user_id = user_id_rech

The stock procedure is used like a table here.

I don't think that doctrine 2 allows to map a stock procedure, but I'd like that someone can confirm that to me.

Implementing the control is exactly the same as implementing it in pure ASP.NET - no difference.

To include it in Sitefinity, you have to register it in the toolbox. Here is the documentation for this: http://www.sitefinity.com/documentation/documentationarticles/adding-controls-to-the-toolbox

Once that's done, you can create a page in Sitefinity and put your custom control on it using drag and drop. Here's a video showing how: http://www.youtube.com/watch?v=LZ4VHGKQsrg

If the response is between 199 and 300 ( >= 200 and < 300 ) or equal to 304 and the responseText can be successfully converted to the dataType that you provide (text by default), it is considered a successful request.

For example, if you return JSON and you get a 200 response status but it fails, it is more than likely a JSON parser problem meaning your JSON is not valid.

If you are returning HTML or XML and it fails with a 200 response status, the responsetext couldn't be converted to HTML or XML respectively (commonly happens in IE with invalid html/xml)

O.K. so I have a solution. I am not sure if it's good enough (since it's a little bit complicated) but whatever...
(If you have other solutions, they will be welcomed :-) )

Steps:

Use CMDB (Configuration management DB) for example puppet.
Set the config and/or dependencies at the needed locations using (CMDB).
Load this resources dynamically (within your code) and add them to your your classpath. The resource location will be taken via JVM parameter.

I suspect the problem is with UserRole Model defition.

var UserRole = sequelize.define('UserRole', { // }, { associate: function(models) { UserRole.belongsTo(models.User, { foreignKey: 'UserId', foreignKeyConstraint: true, targetKey: 'id' }); UserRole.belongsTo(models.Role, { foreignKey: 'RoleId', foreignKeyConstraint: true, targetKey: 'id' }); } db.UserRole.findAll({ //Returns empty })

15416342 0 Unknown extern method T System.Nullable`1::get_Value()

I've run into a problem with my dot42 C# project:

Unknown extern method T System.Nullable`1::get_Value() at System.Void NokiaStyleProfiles.AddDialogue::btnAdd_Click(System.Object,System.EventArgs) (c:\Users\STO\Documents\Visual Studio 2012\Projects\NokiaStyleProfiles\NokiaStyleProfiles\AddDialogue.cs, position 86,13)

Code that's causing that problem:

int hourStart = timePickerStart.CurrentHour.Value; (timePicker.CurrentHour is an int?)

(int), .Value and .GetValueOrDefault(), as expected, produce the same result : this error.

How can i fix it?

15213955 0 What is the intersection of two languages with different alphabets?

I did some googling on this and nothing really definitive popped up.

Let's say I have two languages A and B.

A = { w is a subset of {a,b,c}* such that the second to the last character of w is b }

B = { w is a subset of {b,d}* such that the last character is b }

How would one define this? I think the alphabet would be the union of both, making it {a,b,c,d} but aside from that, I wouldn't know how to make a DFA of this.

If anyone could shed some light on this, that would be great.

30041096 0 c++ pass by reference safely and compile time checking on size

SpiDeviceDriver::SPI_Error SpiDeviceDriver::SPI_ReadBytes( quint32 size_, QVector<quint8>& rxData_ ) { //Get data and fill QVector<quint8> with data }

I'm trying to call a class function (from another class) and pass in a QVector, then fill it with data.

I prefer to just pass in the QVector alone (without the quint32 size parameter) and then figure out the size from that and fill it with data according to its size. However, if the passed in QVector is size 0, I'd either have to assume it is meant to be size 1, creating a new spot for the data, or throw/handle the error at run-time, which i'd rather not do. Compile time error checking would be much better. Is there a better way to do this?
I guess you could pass in a quint32 size_ parameter, then forget what the size of the QVector is and force the resizing to be that size. This seems awkward as well

Note: I've been instructed by my boss to make every function return an enum error code, so just using a size_ and creating a vector, then returning that data is not an option.

15234654 0 JPG Concatenation with Javascript

This is a LONG shot, but maybe someone out here is a super-genius.

I want to combine 4 jpgs in a grid

1 2 3 4

I want to do this client side, without SVG (because IE blows).

I'm looking at manipulating the code inside the jpg files to produce a single, new image. I will get them as all same-sized jpgs, and I can output them to another format (like bitmap) if necessary. I'm also wiling to accept solutions using any special IE "features" like VML. IE8 is the target audience.

I realize I can do this with SVG. I realize I can do this server-side. I realize I can css them next to each other. I need a single image from the 4 originals, as a string is fine (even preferable) because I can base64 encode it and throw it in an image element.

Thanks!

In my opinion, the best way to do this is to simply use the Firebase Realtime Database:

1) Add Firebase support to your app

2) Select 'Anonymous authentication' so that the user doesn't have to signup or even know what you're doing. This is guaranteed to link to the currently authenticated user account and so will work across devices.

3) Use the Realtime Database API to set a value for 'installed_date'. At launch time, simply retrieve this value and use this.

I've done the same and it works great. I was able to test this across uninstall / re-installs and the value in the realtime database remains the same. This way your trial period works across multiple user devices. You can even version your install_date so that the app 'resets' the Trial date for each new major release.

In Visual Studio 2010, you now can apply a transformation to your web.config depending on the build configuration.

When creating a web.config, you can expand the file in the solution explorer, and you will see two files:

Web.Debug.Config
Web.Release.Config

They contains transformation code that can be used to:

Change the connection string
Remove debugging trace and settings
Register error pages

6381302 0 What type of security should I use if I wish to have a Forgotton Password ability on our website? AES?

unfortunately, we've been requested to offer our users the ability to get an email sent to their registered account, their password .. if they have forgotten their password.

"Click here if you have forgotten your password"

So - this means i need to be able to DECRYPT the password. I don't like it, but that's the requirements. I'm used to use a SALT and HASHING a password with SHA1. then storing the salt and the hashed password into the repository.

Not sure what I should be doing if I wish to store the password which can be decrypted now. Is it more or less the same, but I should use AES instead?

Would love some help (and preferably code samples in .NET).

Cheers!

NOTE: Please don't turn this thread into a topic about HASHING vs DECRYPTING vs OpenAuth.

Appears to function as design.

34888901 1 What's the best way to index a large number of arrays for calculating the cosine similarity?

Goal: calculating the most relevant article using cosine similarity.

I have a function that will produce an array of scores of different topics for each article. For example:

[0.6, 0.7, 1] represent the article's scores in the [math, physics, bio] category.

With a given article, I will find the most relevant article by calculating the cosine similarity between the array of given article against the rest of the arrays of other articles.

I am thinking of using pickle to store my data and use numpy to calculate cosine similarity and it can find cosine similarity very fast with matrix manipulation. However I am running into a decision problem as of how to index each array with its corresponding article id.

I have thought of storing each array into a dictionary with the key as the article id and the value as the array. However, i think that will make it hard for me to calculate cosine similarity among a large number of arrays.

Any suggestions and ideas would be greatly appreciated, thanks!

If I have not wrongly misinterpreted your question, then here is what you want to do -

Extract a .tgz file which may have more .tgz files within it that needs further extraction (and so on..)
While extracting, you need to be careful that you are not replacing an already existing directory in the folder.

If I have correctly interpreted your problem, then...
Here is what my code does -

Extracts every .tgz file (recursively) in a separate folder with the same name as the .tgz file (without its extension) in the same directory.
While extracting, it makes sure that it is not overwriting/replacing any already existing files/folder.

So if this is the directory structure of the .tgz file -

parent/ xyz.tgz/ a b c d.tgz/ x y z a.tgz/ # note if I extract this directly, it will replace/overwrite contents of the folder 'a' m n o p

After extraction, the directory structure will be -

parent/ xyz.tgz xyz/ a b c d/ x y z a 1/ # it extracts 'a.tgz' to the folder 'a 1' as folder 'a' already exists in the same folder. m n o p

Although I have provided plenty of documentation in my code below, I would just brief out the structure of my program. Here are the functions I have defined -

FileExtension --> returns the extension of a file AppropriateFolderName --> helps in preventing overwriting/replacing of already existing folders (how? you will see it in the program) Extract --> extracts a .tgz file (safely) WalkTreeAndExtract - walks down a directory (passed as parameter) and extracts all .tgz files(recursively) on the way down.

I cannot suggest changes to what you have done, as my approach is a bit different. I have used extractall method of the tarfile module instead of the bit complicated extract method as you have done. (Just have glance at this - http://docs.python.org/library/tarfile.html#tarfile.TarFile.extractall and read the warning associated with using extractall method. I don`t think we will be having any such problem in general, but just keep that in mind.)

So here is the code that worked for me -
(I tried it for .tar files nested 5 levels deep (ie .tar within .tar within .tar ... 5 times), but it should work for any depth* and also for .tgz files.)

# extracting_nested_tars.py import os import re import tarfile file_extensions = ('tar', 'tgz') # Edit this according to the archive types you want to extract. Keep in # mind that these should be extractable by the tarfile module. def FileExtension(file_name): """Return the file extension of file 'file' should be a string. It can be either the full path of the file or just its name (or any string as long it contains the file extension.) Examples: input (file) --> 'abc.tar' return value --> 'tar' """ match = re.compile(r"^.*[.](?P<ext>\w+)$", re.VERBOSE|re.IGNORECASE).match(file_name) if match: # if match != None: ext = match.group('ext') return ext else: return '' # there is no file extension to file_name def AppropriateFolderName(folder_name, parent_fullpath): """Return a folder name such that it can be safely created in parent_fullpath without replacing any existing folder in it.

You probably want to move your whiteLine subview initialization to initWithStyle:reusedIdentifier: Currently you set up the alpha before it gets instantiated. Also, you're creating a new view every time drawRect: is called, which definitely is a no-no as well.

I'm not currently at the compiler, but something like this should solve your issue:

Note that I also added the autorelease call to your whiteLine subview (I assume it is a retained property). You may want to consider using ARC if you're not comfortable with Cocoa Memory Management. Otherwise I suggest re-reading Apple's Memory Management guide and possibly excellent Google Objective-C Code Style Guide

In BaseCell.m:

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)identifier { self = [super initWithStyle:style reuseIdentifier:identifier]; if (self) { self.whiteLine = [[[UIView alloc] initWithFrame:CGRectMake(0.0, self.frame.size.height-1.0, self.frame.size.width, 1.0)] autorelease]; self.whiteLine.backgroundColor = [UIColor whiteColor]; [self addSubview:self.whiteLine]; } return self; } - (void)dealloc { self.whiteLine = nil; [super dealloc]; } - (void)rowIsOdd:(BOOL)isOdd { self.whiteLine.alpha = (isOdd ? 0.7 : 0.3); }

L2 and L3 caches also have cache lines that are smaller than a virtual memory system page. The size of L2 and L3 cache lines is greater than or equal to the L1 cache line size, not uncommonly being twice that of the L1 cache line size.

For recent x86 processors, all caches use the same 64-byte cache line size. (Early Pentium 4 processors had 64-byte L1 cache lines and 128-byte L2 cache lines.)

IBM's POWER7 uses 128-byte cache blocks in L1, L2, and L3. (However, POWER4 used 128-byte blocks in L1 and L2, but sectored 512-byte blocks in the off-chip L3. Sectored blocks provide a valid bit for subblocks. For L2 and L3 caches, sectoring allows a single coherence size to be used throughout the system.)

Using a larger cache line size in last level cache reduces tag overhead and facilitates long burst accesses between the processor and main memory (longer bursts can provide more bandwidth and facilitate more extensive error correction and DRAM chip redundancy), while allowing other levels of cache and cache coherence to use smaller chunks which reduces bandwidth use and capacity waste. (Large last level cache blocks also provide a prefetching effect whose cache polluting issues are less severe because of the relatively high capacity of last level caches. However, hardware prefetching can accomplish the same effect with less waste of cache capacity.) With a smaller cache (e.g., typical L1 cache), evictions happen more frequently so the time span in which spatial locality can be exploited is smaller (i.e., it is more likely that only data in one smaller chunk will be used before the cache line is evicted). A larger cache line also reduces the number of blocks available, in some sense reducing the capacity of the cache; this capacity reduction is particularly problematic for a small cache.

13918646 0 presentRenderbuffer using memory?

I have simple drawing code like the following - repeated calls to draw several objects, followed by one call to glBindRenderbufferOES and one call to presentRenderbuffer -

Objects draw fine, BUT - the call to presentRenderBuffer allocates a good amount of memory with each call

I've generated and bound frame and render buffers - once - then never really do anything with them after that -

Should I be clearing my buffers after each call to presentRenderBuffer? Or is there some other way to give back memory after calling?

// these four calls made for each object Loop over objects glVertexPointer(3, GL_FLOAT, 0, ... glTexCoordPointer(2, GL_FLOAT, ... glNormalPointer(GL_FLOAT, 0, ... glDrawArrays(GL_TRIANGLES, 0,... // then, one-time call to these glBindRenderbufferOES(GL_RENDERBUFFER_OES, viewRenderbuffer); [context presentRenderbuffer:GL_RENDERBUFFER_OES];

Thread.Abort will close the thread, of course, as it will call Win32 TerminateThread.

Outcome of this action will depend on how your API likes to be closed by TerminateThread.

If your method is called somthing like NuclearPlant.MoveRod() or Defibrillator.Shock(), I'd rather wait these 30 seconds.

This method gives no chance to the victim to do some cleanup:

TerminateThread is used to cause a thread to exit. When this occurs, the target thread has no chance to execute any user-mode code. DLLs attached to the thread are not notified that the thread is terminating. The system frees the thread's initial stack.

As stated in MSDN:

TerminateThread is a dangerous function that should only be used in the most extreme cases. You should call TerminateThread only if you know exactly what the target thread is doing, and you control all of the code that the target thread could possibly be running at the time of the termination. For example, TerminateThread can result in the following problems:

If the target thread owns a critical section, the critical section will not be released.

If the target thread is allocating memory from the heap, the heap lock will not be released.

If the target thread is executing certain kernel32 calls when it is terminated, the kernel32 state for the thread's process could be inconsistent.

If the target thread is manipulating the global state of a shared DLL, the state of the DLL could be destroyed, affecting other users of the DLL.

I think you have to see Density Considerations for Preventing from Scaling.

The easiest way to avoid pre-scaling is to put the resource in a resource directory with the nodpi configuration qualifier. For example:

res/drawable-nodpi/icon.png

When the system uses the icon.png bitmap from this folder, it does not scale it based on the current device density.

You are not changing which object is being referred to by the parameter (which is not allowed here). Instead you are changing the state of the object (which is allowed here).

In other words, when you pass your e1 EmployeeBean object into the method, the x parameter refers to the same object that e1 refers to, and within the method, this cannot change, and so you can't do this:

public EmployeeBean changeFinalvalue(final EmployeeBean x) { x = new EmployeeBean(); // changing the reference is not allowed! return x; }

But what you're doing -- changing the state of the object -- is allowed.

The only way that I know to prevent problems like this is to make a deep copy of the object passed in as parameter and work on the copy/clone object. You could also make the EmployeeBean immutable, but then it wouldn't be much of a Bean, now would it?

Edit: I figured that this question has had to have been asked here many times, and on a little searching, I've found that of course it has. Please look at these links for a good discussion on this. Note that this is a general issue about final variables whether they are method parameters or class fields:

"android:process" and "android:taskAffinity" allows you to have different processes and affinities within the same package (application).

"android:multiprocess" simply means if you want to allow the activity to have a different process-id. This only works within the same app, not when the activity is started from a different a different package.

What are you exactly trying to do? If you want to share the same context and private files, you should use sharedUserId instead (you have to sign them using the same certificate as well).

The Audiere library makes this extremely easy to do. Here's a nearly complete C# program to generate the DTMF tone for the "1" button:

AudioDevice device = new AudioDevice(); OutputStream tone1a = device.CreateTone(697); // part A of DTMF for "1" button OutputStream tone1b = device.CreateTone(1209); // part B tone1a.Volume = 0.25f; tone1b.Volume = 0.25f; tone1a.Play(); tone1b.Play(); Thread.Sleep(2000); // when tone1a stops, you can easily tell that the tone was indeed DTMF tone1a.Stop();

To use Audiere in C#, the easiest way to get up and running is to use Harald Fielker's C# binding (which he claims works on Mono and VS; I can confirm it works in the both full version of VS2005 and using the separate Express 2008 versions of C# and VC++). You'll need to download the Win32 Audiere DLL, lib, and header (which are all in the same zip) and you'll need to build the C# binding from source using both VC++ and C#.

One of the nice benefits of using Audiere is that the calls are non-blocking. You don't have to wait for tone1a to stop playing before you start tone1b, which is clearly a necessity for playing complex tones. I am not aware of any hard upper limits on how many simultaneous output streams you can use, so it's probably whatever your hardware/OS supports. By the way, Audiere can also play certain audio files (MP3, WAV, AIFF, MOD, S3M, XM, IT by itself; Ogg Vorbis, Flac, Speex with external libraries), not just pure generated tones.

One possible downside is that there is a slightly audible "click" as you start or stop an individual tone; it's not noticeable if you add one tone to an already playing tone. The easiest workaround I've found for that is to slowly ramp the tone's volume up or down when you're turning the tone on or off, respectively. You might have to play around with the ramp speed to get it to sound "just right".

Note that Audiere is LGPL-licensed, and the binding has no license attached to it. You'll have to consult your legal team or try to get a hold of Harald if you want to use his binding in a commercial product; or you could just make your own binding and avoid the hassle.

@Tom: Since there is no specific license attached to Harald's library, I'm not sure what implications would come of hosting it; however, I believe I can at least give you fine detail on exactly how my libaudieresharpglue project is set up.

Using Visual C++ Express 2008, open up bindings/csharp/libaudieresharpglue/vc8.0/libaudieresharpglue.sln. VC++ will automatically convert the solution to a VS9 solution.

In another folder, you should have the Audiere package from Sourceforge. Under your VC++ project properties, go to Configuration Properties > C/C++ > General, and make sure you have path/to/audiere-1.9.4-win32/include in your "Additional Include Directories." Then, in that same window, go to Linker > General and make sure you have /path/to/audiere-1.9.4-win32/lib in your "Additional Library Directories." Then, you should be able to build the project (preferably in Release mode) and this output libaudieresharpglue.dll in your vc8.0/Release folder.

Next, open up Visual C# Express 2008. Open up bindings\csharp\test\vc8.0\AudiereCSharpTest.sln and let it convert the solution. The project should build fine, but then you will get an error when you run it. That's fine; in your csharp/test/vc8.0/bin/Release folder, you need to add both libaudieresharpglue.dll from the VC++ solution and audiere.dll from the package from Sourceforge.

Now, you should be able to build and run AudiereCSharpTest. Note that by default, #define stream_test is not commented out at the top of AudiereTest.cs, and that will reference a file that is not on your hard drive. You can simply comment out that #define and uncomment noise_test or square_test.

That should cover it; if I missed any details, hopefully they are small enough to get by on your own :)

29108765 0 How do I AJAX post to an MVC action from within a javascript file?

The following code exists in a file called job.js. When I run this code against localhost everything behaves properly. When I do so against my intranet server where there is an application name I get a 404.

Job.updateJob = function () { $.post('/Builder/ListJobItems', function (data) { ... }); }

I would love to use @Url.Action() but as I said this is javascript (.js) file. I am also aware of the hack where you put a data value onto the body element, but for architectural reasons, I want this code to be decoupled from the DOM. It is a data acquisition engine, why should it even know what a DOM is.

I would be fine with a solution that parses window.location in some fashion, but the problem that I am having their is that I need a solution that will work everywhere.

What frustrates me most is that I can't see how this isn't a problem everyone would face. Why isn't there a solution? Does everyone just put all of their JavaScript into the razor view? Does no one isolate code into modules anymore? I can't believe either of these is true, and yet there don't seem to be any forth coming solutions for this. I am at a loss.

You don't have to call Flush() on Close()/Dispose(), FileStream will do it for you as you can see from its source code:

 [System.Security.SecuritySafeCritical] // auto-generated protected override void Dispose(bool disposing) { // Nothing will be done differently based on whether we are // disposing vs. finalizing. This is taking advantage of the // weak ordering between normal finalizable objects & critical // finalizable objects, which I included in the SafeHandle // design for FileStream, which would often "just work" when // finalized. try { if (_handle != null && !_handle.IsClosed) { // Flush data to disk iff we were writing. After // thinking about this, we also don't need to flush // our read position, regardless of whether the handle // was exposed to the user. They probably would NOT // want us to do this. if (_writePos > 0) { FlushWrite(!disposing); // <- Note this } } } finally { if (_handle != null && !_handle.IsClosed) _handle.Dispose(); _canRead = false; _canWrite = false; _canSeek = false; // Don't set the buffer to null, to avoid a NullReferenceException // when users have a race condition in their code (ie, they call // Close when calling another method on Stream like Read). //_buffer = null; base.Dispose(disposing); } }

Instead of removing all listeners each event maybe pass in a channel that has event details put to it. The same channel should go to the button's logic handler where it will repeatedly be taken from.

Yes CubeGrid is available to Power and Enterprise license holders from Isomorphic. Check out the CubeGrid and Facets classes and take a look at the show cases on the smartgwt pages.

http://www.smartclient.com/smartgwtee/showcase/#cube_analytics and follow examples.

If you are just able to use ListGrid you can achieve the same thing through iterating through the records. If you are able to use a database you can enter customSQL

such as:

<operationBindings> <operationBinding operationType="fetch" operationId="VEP_AREA_RECORD"> <customSQL> SELECT * FROM (SELECT SUBSTRING(MeasurementTime,7,4) [Year], CASE SUBSTRING(Time,1,2) WHEN '01' THEN 'Jan' WHEN '02' THEN 'Feb' WHEN '03' THEN 'Mar' WHEN '04' THEN 'Apr' WHEN '05' THEN 'May' WHEN '06' THEN 'Jun' WHEN '07' THEN 'Jul' WHEN '08' THEN 'Aug' WHEN '09' THEN 'Sep' WHEN '10' THEN 'Oct' WHEN '11' THEN 'Nov' WHEN '12'THEN 'Dec' END as [Month], [value] , [col1] as col1, col1 [col1_name], col2 [col2_name], col3 [col3], [col4_name] FROM your_table WHERE MeasurementValue IS NOT NULL) TableDate PIVOT <what you want in rows> FOR [Month] IN ( [Jan],[Feb],[Mar],[Apr], [May],[Jun],[Jul],[Aug], [Sep],[Oct],[Nov],[Dec] ) ) AS PivotTable ORDER BY groupCol1, groupCol2 </customSQL>

clearly these columns could be actual values in your records/db or derived (in my case derived from the datefield. I"m not a SQL guru so if there's a better way I'd love to hear it.

In the above exmple the output would be

 [jan] [feb] [mar] etc.....in your case [col1_valA] [col2_val1] valx valy [col1_valB] [col2_val2

I need to draw some graphics over google maps. Graphics is not always transparent, so I'd like to draw text labels (country names, city names, etc.) over my graphics.

For graphics I use overlay map type , it is shown over base map. But I failed to draw labels over it?

I guessed that there shall be a way to draw base map twice, with different style settings (so I style map with not labels, put my overlay, and then put overlay with roadmap with labels only), but it does not seem like I can use basic map types as overlay ones. Another way I see is to manually get tile with labels only by composing URL. This works, but as far as I understand accessing map tiles directly is prohibited by ToS.

Is there a working and, well, legal way to do that?

Here is jsfiddle which illustrates URL composing solution: https://jsfiddle.net/GRaAL/jyr81p2c/

// here is how I get google maps tile with labels only function getLabelsOnlyTile(coord, zoom) { return "https://maps.googleapis.com/maps/vt?pb=!1m5!1m4!1i" + zoom + "!2i" + (coord.x) + "!3i" + (coord.y) + "!4i512!2m3!1e0!2sm!3i353022921!3m14!2sen!3sUS!5e18!12m1!1e47!12m3!1e37!2m1!1ssmartmaps!12m4!1e26!2m2!1sstyles!2zcC52Om9mZixzLmU6bHxwLnY6b24!4e0"; }

! is used to reference one member of a collection ... CollectionName!MemberName

Forms is the name of a collection whose members are Form objects, and includes those forms which are currently open in your Access session.

A Form has a collection of Control objects. So appending !ControlName to the form reference gets you a reference to that control.

So Forms![HiddenUserCheck]![txtStatus] refers to a control named txtStatus in a form named HiddenUserCheck which is open in your Access session.

What you get from that reference is the control's default property, Value ... the value contained in that control.

27306129 0 String inside structure behavior

Let's say we have structure

struct MyStruct { public string a; }

When we assign it to the new variable what will be happened with the string? So for example, we expect that string should be shared when structs are copied in the stack. We're using this code to test it, but it returns different pointers:

 var a = new MyStruct(); a.a = "test"; var b = a; IntPtr pA = Marshal.StringToCoTaskMemAnsi(a.a); IntPtr pB = Marshal.StringToCoTaskMemAnsi(b.a); Console.WriteLine("Pointer of a : {0}", (int)pA); Console.WriteLine("Pointer of b : {0}", (int)pB);

The question is when structs are copied in the stack and have string inside did it share the string or the string is recreated?

[UPDATE]

We also tried this code, it returns different pointers as well:

 char charA2 = a.a[0]; char charB2 = b.a[0]; unsafe { var pointerA2 = &charA2; var pointerB2 = &charB2; Console.WriteLine("POinter of a : {0}", (int)pointerA2); Console.WriteLine("Pointer of b : {0}", (int)pointerB2); }

When overriding a virtual method, you must keep the original "contract" of the method, which in your case is a string a variable.

In order to do what you want, you can create a virtual overload which takes two strings:

public class A { public virtual void DoSomething(string a) { // perform something } public virtual void DoSomething(string a, string b) { // perform something } } public class B : A { public override void DoSomething(string a, string b) { // perform something slightly different using both strings } }

If what you want is to accept N strings in your method, you can use the params keyword:

public class A { public virtual void DoSomething(params string[] allStrings) { // Do something with the first string in the array // perform something } }

33419570 0 jquery validate requires two clicks to submit

I have a form that has two buttons. One to edit a specific candidate after the information has been submitted, another button to just submit and add another candidate. Since there are two buttons on the screen, I need to know which one was clicked so that I can escort the user down the right path.

I am using the jQuery Validation Plugin to help me validate the form before posting it. To prevent users from double clicking the button and submitting a duplicate candidate, I am disabling the button and changing the button to "Submitting" as demonstrated here:

/* This will change the button only if the form has passed and change the button to submitting and disable it */ submitHandler: function(form) { $('#saveandadd').click(function() { $('#saveandadd').val('Submitting...'); $('saveandadd', this).attr('disabled', 'disabled'); form.submit(); }); $('#saveandedit').click(function() { $("input[name='setvalue']").val('1'); $('#saveandedit').val('Submitting...'); $('saveandedit', this).attr('disabled', 'disabled'); form.submit();

So far this is nice as I can change the button that was clicked to submitting. However, I have noticed a strange problem. Either button requires two clicks to submit it.

I have setup a fiddle here: Form Validation that requires the first and last name to be filled in. You will be prompted as an error if those fields are not filled in.

Thanks in advance

First of all, this is how you do it:

var outer = function() { this.inner = { innermost: function() { alert("innermost"); } } } var outer = new outer; outer.inner.innermost();

The reason why it didn't work the way you did it is because you define a function inner - so outer.inner is a function. You could do var inner = new (outer.inner)(); and then call inner.innermost(); but that's obviously ugly and not what you want.

37389340 0 Can not find module TypeScript

I am converting my nodejs project into typescript nodejs. I have changed the extensions of .js files to .ts, however now I am getting require() errors. To overcome this problem, I tried

import express from "express"

However this gives me "Can not find module error". I have researched it and narrowed it down to the issue where I guess TypeScript needs express.d.ts file for detecting the Express module. However I couldn't find the express.d.ts file anywhere in my project. Which ultimately means I am missing something.

Can somebody point me in the right direction or perhaps help me resolve this problem?

Basically if a user gets any error other than 403 or 404 (most notable other than those is 500 which is sent if there's an exception) they'll be redirected to that page, which won't exist (And if you're in IIS7 integrated pipeline or have IIS6 wildcard mapped they'll then get bounced to FileNotFound.htm - otherwise they'll just see a standard 404).

It'd probably be nice to at least give the user a "Oh no! Something is wrong!" page.

ok, looks like sqlite either doesn't have what I need, or I am missing it. Here's what I came up with:

declare zorder as integer primary key autoincrement, zuid integer in orders table

this means every new row gets an ascending number, starting with 1
generate a random number:

rnd = int(random.random() * 1000000) # unseeded python uses system time
create new order (just the SQL for simplicity):

'INSERT INTO orders (zuid) VALUES ('+str(rnd)+')'
find that exact order number using the random number:

'SELECT zorder FROM orders WHERE zuid = '+str(rnd)
pack away that number as the new order number (newordernum)
clobber the random number to reduce collision risks

'UPDATE orders SET zuid = 0 WHERE zorder = '+str(newordernum)

...and now I have a unique new order, I know what the correct order number is, the risk of a read collision is reduced to negligible, and I can prepare that order without concern that I'm trampling on another newly created order.

Just goes to show you why DB authors implement sequences, lol.

LINQ statements return IEnumerable objects, and your method is returning a single Request object. In your case looks like you only need to return the first result of the LINQ statement.

Something like:

 Dim pr = (From r In dc.Request From p In dc.Process.Where(Function(v) v.IdReq = r.IdReq And v.idProcess Is Nothing) Select New {Request = r}).FirstOfDefault Return pr

19243938 0 Keep the text in textboxes saved

I have these textboxes where the user enters data and then presses a button to process the data. Now the data entered by the user is alot and to give the user some slack I want to make it possible whenever you press the button, the application saves the data, so when you close the application and start it back up again the textboxes are filled with the last entered data.

I was thinking about using a .txt file to save the data. Only I have found some difficulties with this. One of the problems is that I keep getting a messagebox from the microsoft .NET Framework everytime I try to run my application. The messagebox says the Index was outside the bounds of the array. Even though I think my code doesn't exceed the bounds of my array.

And here is the code that I use:

First I declared an array and filled it with variables that contain the content of the textboxes:

string[]settings = new string[5]; settings[0] = openKey; settings[1] = secretKey; settings[2] = statusRequestPath; settings[3] = statusRequestAPI; settings[4] = setSeconds.ToString();

Then I use the following code to write the data to a text file.

using (StreamWriter writeFile = new StreamWriter(@"C:\Audio Silence Detector\AudioSilenceDetector.txt")) { foreach (string line in settings) { writeFile.WriteLine(line); } }

And to put the text of the .txt file back in the application I have put this in the formload:

string[] lines = System.IO.File.ReadAllLines(@"C:\Audio Silence Detector\AudioSilenceDetector.txt"); tbOpenKey.Text = lines[0]; tbSecretKey.Text = lines[1]; tbStatusRequestPath.Text = lines[2]; tbStatusRequestAPI.Text = lines[3]; tbSeconds.Text = lines[4];

I changed my code to this and it seems to have fixed the issue I was having:

 if (lines.LongLength == 5) { tbOpenKey.Text = lines[0]; tbSecretKey.Text = lines[1]; tbStatusRequestPath.Text = lines[2]; tbStatusRequestAPI.Text = lines[3]; tbSeconds.Text = lines[4]; }

try simply indicating ctypes the argtypes it takes and the ones it returns:

nDll = ctypes.WinDLL('ndll.dll') nDll.restype = ctypes.c_double nDll.argtypes = [ctypes.c_char_p] result = nDll.iptouint("12.345.67.890").value

Although, consider these points:

1) if, as the name indicates, this converts an IPv4 value s ina string to an Unsigned Int, the return type os not "double" as you say - it would be ctypes.c_uint32

2) Your example value is not a valit IPv4 address, and cannot be converted to a 32 bit integer (neither does it makes sense as a "double" - i.e. a 64 bit floating point number) - it is simply invalid

3) You don't need that if you are just trying to have an unsigned 32bit value for an ipv4 address in Python. There are quite a few, very readable, easier, and multiplatform ways to do that with pure python. For example:

def iptoint(ip): value = 0 for component in ip.split("."): value <<= 8 #shifts previous value 8 bits to the left, #leaving space for the next byte value |= int(component) # sets the bits for the new byte in the address return value

update: In Python 3.x there is the ipaddress module - https://docs.python.org/3/library/ipaddress.html - which is also available as a pip install for Python 2.x - it can handle this always in the correct way, and works fine with IPv6 as well.

15149118 0 Text Lines are missed when reading a file Line by Line in Perl. mismatch

I want to extract and log various parameters from a 3G modem as there are intermittent dropouts. As such I am using wget to read 3Ginfo.html from a 3G modem and placing the contents into a file contents.txt. Using Notepad++ to open this file shows all of the data.

Due to my reputation, I cannot post pictures, therefore the code below is the best I can do; from Notepad++ (with View All Characters turned on), I get:

<tr>[LF] <td class='hd'>Signal Strength:</td>[LF] <td>[LF] -72[CR] &nbsp(dBm)&nbsp(High)</td>[LF] </tr>[LF]

However, when the file is read line by line from Perl, it is clear that there are less lines than those reported by Notepad++ and data is missing. In this case the actual signal strength value is missing.

Here is the Perl code to read the file:

open hLOGFILE, "<output.txt"; while (<hLOGFILE>) { print "Line no $. Text is $_ "; }

Here is the output (as text, because I cannot post pictures yet):

Line no 98 Text is <tr> Line no 99 Text is <td class='hd'>Signal Strength:</td> Line no 100 Text is <td> &nbsp(dBm)&nbsp(High)</td> Line no 102 Text is </tr>

It is clear that there are missing lines and it is related to the <cr> end of line terminator. I have tried slurping the file and the lines are still missing.

Apart from reading byte by byte and then trying to parse the file that way (which is not very appealing) I can not find a solution.

My plan is to simply extract and log the lines of interest every minute or so.

I have tried opening the file specifying various encoding but still no joy. If Notepad++ can read and display all the data, why does it not work in Perl. When using more from the Windows XP command line, it show that the data is also missing.

When I view source from chrome I get,

<tr> <td class='hd'>Received Signal Code Power(RSCP):</td> <td align='center'> -78 dBm</td> </tr>

I was looking at this example w.r.t executing code in the stack:

#include <stdio.h> #include <stdlib.h> #include <string.h> char shellcode[] = “\xeb\xfe”; int main(int argc, char *argv[]){ void (*f)(); char x[4]; memcpy(x, shellcode, sizeof(shellcode)); f = (void (*)()) x; f(); }

This causes a segmentation fault. My understanding this is because the shellcode runs out of memory for the rest of the bytes as x only has a size of 4 bytes. And this results in creating a write operation of copying to stack memory and that causes a seg. fault as stack memory is read only. Is my understanding correct ?

The advantages are that it helps you to follow the "let it crash" rule in your application, and it concentrates in a few line of code the complex task to coordinate all your processes.

I use gen_event mainly for logging purposes. You can use this behavior to connect on demand different handlers depending on your target. In one of my application, I have by default a graphical logger that allows to check the behavior at a glance, and a textual file handler that allows deeper and post mortem analysis.

Gen_server is the basic brick of all applications. It allows to keep a state, react on call, cast and even simple messages. It manages the code changes and provides features for start and stop. Most of my modules are gen_servers, you can see it as an actor which is responsible to execute a single task.

Gen_fsm brings to gen server the notion of a current state with a specific behavior, and transition from state to state. It can be used for example in a game to control the evolution of the game (configuration, waiting for players, play, change level...)

When you create an application you will identify the different tasks yo have to do and assign them to either gen_server either gen_fsm. You will add gen_event to allow publish/subscribe mechanism. Then you will have to group all processes considering their dependency and error recovering. This will give you the supervision tree and restart strategy.

22831653 0 Find applications starting with a specific string applescript

I want to find if an application is installed using AppleScript.

The application can have different versions installed in the same PC.

Hence, the name of the application is in the format "FooBar vXX.XX"

Now, when I tried

tell application "Finder" to get application "FooBar"

The script launched a pop up, asking the user to find the app manually. Because, I didn't give the full name of the application - which includes the version number.

My query is, how can I find the installed application without its full name? This is necessary because I don't know which version is installed.

Can I use a regex in this case - How do I use it in this example?

I have a page that offers the user results. From that page there are additional sort options and advanced search options that are submitted by POST by AJAX to a script and the output is inserted into a div using jquery.

Once the user clicks one of the results, they are redirected to the details page. When I click back from that page it doesnt load says form submission error.

Not sure what to be looking for all the stuff I have seen is for when there are simply multiple ajax pages in one page.

I've not tested this, but I think you can request the page using ajax and check the response code - if there's no errors and the status code is 200 then the page is accessible.

First, replace cat $strLocalDir"config.txt" by cat "${strLocalDir}config.txt".

Then, check what does config.txt contains ? This will be moved to the $URLS variable, maybe it s not well formed.

When you have such problems try to insert debug statements, like print. Test the value of your variables each time they're needed, you'll know more precisely where does the code fail.

Why detect and comput are 2 different operation?

.compute

Takes ~1sec. Is there any way to speed up .compute ?

Without seeing the import statement that you tried, I am not 100% sure about why is that happening... But perhaps the reason is that you are using the default delimiter for fields, which is precisely a comma, so if you want to keep it, you should use a different delimiter, like for example:

--fields-terminated-by \t

Another option would be to use --enclosed-by '\"', and it would look like "sami, ramesh".

Hope that helps! If it doesn't, please post your import statement to see where the problem is.

I can't help much without knowledge about Java BufferedImage,Graphics, PrinterJob and other related classes implementation. (You may start a bounty for this question to possibly draw attention of people having more intristic knowledge about java awt graphic stuff).

As you obviously must have noticed using BufferedImage (or not using it) is what makes a difference in SVG output. In the version that works you draw the rectangle directly on Graphic context provided to you as print() method argument and I believe that's how it was designed to be used by authors of Printable interface and printing framework.

In the second approach (that doesn't work correct) you first draw rectangle onto new BufferedImage object and then draw this image on the provided Graphic context. So you do something much less straightforward than just drawing directly on the context. There is well known truth or intuition among developers that the less straightforward way do you use some API, the bigger is a chance that you do something unexpected by its authors :(.

My hypotesis is following: BufferedImage is (as you can deduce from its Javadocs)just a raster image, ie. grid of pixels. That's why svg file is populated with lots of small rectangles (trying to mimic pixels). The Graphics object provided by draw() method may be more abstract and operate on shapes rather than pixels, which is much more appropriate to be written to vector graphics formats like SVG. But that's just hypotesis.

The question is, do you really need to use BufferedImage? If I understand correctly, you want user to be able to edit rectangle on screen and when ready export it to SVG. Can't you just remember for example upper left corner and dimensions of rectangle edited by user and then use this data to recreate this rectangle directly on Graphics object provided by print(), like:

public int print(Graphics g, PageFormat pf, int page) throws PrinterException { ... g.fillRect(userRect.x,userRect.y,userRect.width,userRect.height); ... }

(userRect is object of your own custom class which just stores data about image edited by user)

That's a very good question which actually made me realise that we don't have it documented. We'll fix it.

As for now the expected format looks like this (you can use MongooseIM's debug shell to generate it).

scram:serialize(scram:password_to_scram(<<"ala_ma_kota">>, 4096)). <<"==SCRAM==,xB2++RvZklv0rV5I1iuCpoxLqL0=,sKXBkOFrtyGxKqYo/dlzeKfYszU=,oplvMJ5VDxQ7rJZuIj0ZfA==,4096">>

In other words, MongooseIM expects the format to be:

==SCRAM==,StoredKey,ServerKey,Salt,IterationCount

the ==SCRAM== prefix is constant, other parts depends on the password.

Hope that helps.

No. It's not a redundant parameter; the code that utilizes a SalesStrategy should not know which concrete class it is using, so the method signature must be identical in all derived classes.

37181181 0 Right way to store Image in database through Entity Framework

I have converted an image to a byte array using below code to store it in Database

 if (Request.Content.IsMimeMultipartContent()) { var provider = new MultipartMemoryStreamProvider(); await Request.Content.ReadAsMultipartAsync(provider); foreach (var file in provider.Contents) { var filename = file.Headers.ContentDisposition.FileName.Trim('\"'); var attachmentData = new AttachmentData (); attachmentData.File = file.ReadAsByteArrayAsync().Result; db.AttachmentData.Add(attachmentData); db.SaveChanges(); return Ok(attachmentData); } }

Here File column in DB is of type "varbinary(max)" and in EF model it is byte array (byte[]).

Using above code I was able to save the image in the File column something similar to "0x30783839353034453437304430413143136303832....." (This length is exceeding 43679 characters which is more than default given to any column so the data got truncated while storing it)

I have to change the default length(43679) of column to store it in database.

Am I doing it the correct way to retrieve and store image in Database. I was also thinking to store the image as "Base64 String" but 43679 will still exceed.

I am using Angular JS to show the image on front end which uses WebAPI to fetch and save the image as ByteArray in database.

32701824 0 Swift: Comparing Implicitly Unwrapped Optionals results in "unexpectedly found nil while unwrapping an Optional values"

If got this class and would like to compare instances of it based on the value

class LocationOption: NSObject { var name:String! var radius:Int! var value:String! override func isEqual(object: AnyObject?) -> Bool { if let otherOption = object as? LocationOption { return (self.name == otherOption.name) && (self.radius == otherOption.radius) && (self.value == otherOption.value) } return false } }

When executing this:

var a = LocationOption() var b = LocationOption() a.name = "test" b.name = "test" if a == b { // Crashes here!! print("a and b are the same"); }

This crashes with "unexpectedly found nil while unwrapping an Optional value"? You can copy all this into a Playground to reproduce.

It seems to be due to the Implicitly Unwrapped Optionals. If I declare all fields as Optionals it works as expected.

But in my case, I would like to have these properties as Implicitly Unwrapped Optionals. How should I write the isEqual?

===

UPDATE: @matt is right and as I didn't want to change to "regular" Optionals I ended up with this:

class LocationOption: Equatable { var name:String! var requireGps:Bool! var radius:Int! var value:String! } func ==(lhs: LocationOption, rhs: LocationOption) -> Bool { let ln:String? = lhs.name as String?, rn = rhs.name as String? let lr = lhs.radius as Int?, rr = rhs.radius as Int? return ln == rn && lr == rr }

The "correct" way according to the Java EE architecture would be to have a JCA connector to do inbound/outbound connection with the SMTP server.

The JCA connector can do whatever you want, including threading and connection to external systems with sockets. Actually JMS is just a special kind of JCA connector that connects to JMS broker and delivers message to "regular" MDB. A JCA connector can then poll the SMTP server and delivers the message to a custom MDB.

The best document about JCA is Creating Resource Adapters with J2EE Connector Architecture 1.5, and it does actually use the example of email delivery. Luck you :) I suggest you have a look at it. The code can be found as part of the Java EE samples and uses JavaMail, but I don't know if it's production ready.

The parameters to glfwOpenWindow are specifying the desired values. However, it's entirely possible that your driver doesn't support the exact format you're asking for (24 bit color, 24 bit depth, no alpha, no stencil). GLFW will attempt to find the best match while meeting your minimums.

In this case it's probably giving you the most standard format of RGBA color (32 bit) and a 24/8 bit depth/stencil buffer, or it could be creating a 32 bit depth buffer. You'd actually need to call glfwGetWindowParam to query the depth and stencil bits for the default framebuffer, and then build your renderbuffers to match that.

16330171 0 Anorm says no results were returned for select query preceded by inserts (PSQLException: No results were returned by the query)

I'm writing a Play 2 application with a Postgres backend.

My code has a sql string which is a concatenation of two inserts and a select. Then when I try to execute my query, anorm blows up and says me no results have been returned. I could break it up into two separate queries but then I'd be making an unnecessary trip to the database?

The sql string is pretty simple.

val sql = """ insert into gameconstants ... values ...; insert into gamevariables ... values ...; select lastval() as gameid; """

Then the code that throws the exception just tries to get the gameid from query. This should work right?

DB.withTransaction { implicit connection => val gameid = SQL(sql).on( ... )() .map(row => row[Long]("gameid")).head }

Here is the error [PSQLException: No results were returned by the query.]

This depends on how your struct is defined, whether or not you want your output to be human-readable, and whether or not the output file is meant to be read on a different architecture.

The fwrite solution that others have given will write the binary representation of the struct to the output file. For example, given the code below:

#include <stdio.h> int main(void) { struct foo { int x; char name1[10]; char name2[10]; } items[] = {{1,"one","ONE"}, {2,"two","TWO"}}; FILE *output = fopen("binio.dat", "w"); fwrite( items, sizeof items, 1, output ); fclose( output ); return 0; }

if I display the contents of binio.dat to the console, I get the following:

 john@marvin:~/Development/Prototypes/C/binio$ cat binio.dat oneONEtwoTWOjohn@marvin:~/Development/Prototypes/C/binio$ john@marvin:~/Development/Prototypes/C/binio$ od -c binio.dat 0000000 001 \0 \0 \0 o n e \0 \0 \0 \0 \0 \0 \0 O N 0000020 E \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 0000040 \0 \0 \0 \0 002 \0 \0 \0 t w o \0 \0 \0 \0 \0 0000060 \0 \0 T W O \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 0000100 \0 \0 \0 \0 \0 \0 \0 \0 0000110

The integer values show up as garbage (not reproduced above) because they've been stored as the byte sequences 01, 00, 00, 00 and 02, 00, 00, 00 (x86 is little-endian), which are not printable characters. Also note that all 10 characters of name1 and all 20 characters of name2 are written to the file, which may or may not be what you want.

The situation gets even more complicated if your struct contains pointers, because what gets stored to the file is the pointer value, not the thing being pointed to:

#include <stdio.h> int main(void) { struct foo { int x; char *name1; char *name2; } items[] = {{1,"one","ONE"}, {2,"two","TWO"}}; FILE *output = fopen("binio.dat", "w"); fwrite( items, sizeof items, 1, output ); fclose( output ); return 0; }

This time I get

 john@marvin:~/Development/Prototypes/C/binio$ cat binio.dat ��������john@marvin:~/Development/Prototypes/C/binio$ john@marvin:~/Development/Prototypes/C/binio$ od -c binio.dat 0000000 001 \0 \0 \0 260 205 004 \b 264 205 004 \b 002 \0 \0 \0 0000020 270 205 004 \b 274 205 004 \b 0000030

Note that none of the strings appear in the file at all; if you read this file in with a different program, all it will see are (most likely) invalid addresses.

If you want your output to be human-readable and you want to be able to read those values in on a different architecture, you almost have to go with formatted output, meaning you have to write each member separately:

#include <stdio.h> int main(void) { struct foo { int x; char *name1; char *name2; } items[] = {{1,"one","ONE"}, {2,"two","TWO"}}; FILE *output = fopen("binio.dat", "w"); int i; for (i = 0; i < sizeof items / sizeof items[0]; i++) { fprintf(output, "%d %s %s\n", items[i].x, items[i].name1, items[i].name2); } fclose( output ); return 0; }

 john@marvin:~/Development/Prototypes/C/binio$ cat binio.dat 1 one ONE 2 two TWO

You can certainly wrap that operation in a function of your own, something like

int printFoo( FILE *output, const struct foo item ) { return fprintf( output, "%d %s %s\n", item.x, item.name1, item.name2); }

but in the end, that's about as simple as it gets.

The fwrite solution works great if you're not concerned about readability and portability, but you still have to be careful if you have any pointer members within the struct.

The situation is this:

I have more than one remote repository - for reference, lets say that one is the "alpha" repository, and we have recently set up a new "beta" repository, which some users have migrated to.

Both repositories have a "master" branch.

How do I set up my local master such that it will attempt to automatically push and pull to and from both the alpha and beta repositories, without manually specifying the remote I want to use each time?

I should elaborate that I don't want to set up two local branches 'master-alpha' and 'master-beta', I want the same local branch to track both remotes.

"I'm thinking more TDD, like in an OOP language. Is such a thing possible in Haskell?"

A better question is "is such a thing necessary in Haskell?" ;-)

[I realise that is not the question you actually asked. Feel free to ignore this answer.]

In an OO language, we build objects that talk to other objects to get their job done. To test such an object, we build a bunch of fake objects, hook the real object up to the fake ones, run the method(s) we want to test, and assert that it calls faked methods with the expected inputs, etc.

In Haskell, we write functions. The only thing a pure function does is take some input, and produce some output. So the way to test that is to just run the thing, feeding it known inputs and checking that it returns known outputs. What other functions it calls in the process of doing that doesn't matter; all we care about is whether the answer is right.

In particular, the reason we don't usually do this in OOP is that calling some arbitrary method might cause "real work" to happen — reading or writing disk files, opening network connections, talking to databases and other servers, etc. If you're just testing one part of your code, you don't want the test to depend on whether some database is running on a real network server somewhere; you just want to test one little part of your code.

With Haskell, we separate anything that can affect the Real World from stuff that just does data transformations. Testing stuff that just transforms data in memory is delightfully trivial! (Testing the parts of your code that do interact with the Real World is still hard, in general. But hopefully those parts are very small now.)

The Haskell test style of choice seems to be property-based testing. For example, if you've got a function to solve an equation, you write a QuickCheck property that randomly generates 100 equations, and for each one, it checks whether the number returned actually solves the original equation or not. It's a tiny handful of code that automatically tests just about everything you'd ever want to know! (But not quite: You need to make sure that the "randomly" chosen equations actually test all the code paths you care about.)

You can see there are comments in aapt_rules.txt. Beside each kept class there are corresponding layout files that referenced this class. Like that:

# view res/layout/abc_list_menu_item_layout.xml #generated:17 # view res/layout/abc_popup_menu_item_layout.xml #generated:17 -keep class android.support.v7.internal.view.menu.ListMenuItemView { <init>(...); }

If you remove the layout file from build process this line will desappear and class will not be kept. The class will be shrinked if it's not actually used somewhere.

So how can we remove layout file from appcompat library? I can see few options, none of them is perfect but they work.

You can just remove file from sdk\extras\android\m2repository\com\android\support\appcompat-v7\version\appcompat-v7-version.aar. Enough for testing, bad for production because the same file may be used in some other projects. I tried and it works.
Put fake file with the same name into your project. Name conflict will happen. Build process will prefer your fake file because project files have higher priority. This way file from appcompat will be ignored. I tried and it works.
Probably you can make some fancy gradle script that removes unwanted files during the build process. I haven't tried that.

(shrinkResources option doesn't help because aapt_rules.txt is generated BEFORE shrinkResources is actually involved.)

I hope somebody will suggest a better way to do that

After doing that all unwanted lines were gone from aapt_rules.txt. But it saved me about 100 KB from the final apk size. So not big deal for me. But in your case results may be different.

I don't claim to fully understand the why here, but as best I can tell, this is what's going on.

summary.default actually calls oldClass rather than class. Why I'm not sure, although I'm sure there's a good reason.

Somewhat cryptically in ?class we find the following passages:

Many R objects have a class attribute, a character vector giving the names of the classes from which the object inherits. If the object does not have a class attribute, it has an implicit class, "matrix", "array" or the result of mode(x) (except that integer vectors have implicit class "integer"). (Functions oldClass and oldClass<- get and set the attribute, which can also be done directly.)

So what's going on here is that class returns the implicit class (numeric). Note that attr(a$alpha,"class") returns NULL. Since the attribute doesn't exists, oldClass faithfully returns NULL.

As for the differences between mode, type and class, the first two are related, the third is sort of a separate idea. Mode and type are (I think) actually fairly well explained in the documentation. mode tells you the storage mode of an object, but it is relying on the result of typeof, so they are (mostly) the same. Or connected, at least. But the different values that typeof returns are simply collapsed down to a smaller subset.

you can do on a other way:

Create a Select with this Concats

select GROUP_CONCAT( CONCAT(" ('",field1,"','",field2,"')")) as vals from my_table;

The Result look like this:

Result

mysql> select GROUP_CONCAT( -> CONCAT(" ('",field1,"','",field2,"')")) as vals -> from my_table; +---------------------------------------------------------------------------------------------------------+ | vals | +---------------------------------------------------------------------------------------------------------+ | ('O1','AC'), ('O1','PT'), ('O2','PT'), ('O3','MI'), ('O3','PT'), ('O4','EG'), ('O4','PT'), ('O5','PT') | +---------------------------------------------------------------------------------------------------------+ 1 row in set (0,00 sec) mysql>

and the you can direct concat this in the insert statement and you only read one row and only write and execute one statement.

your Code

 String selectStatement = "SELECT GROUP_CONCAT(CONCAT(" ('",field1,"','",field2,"')")) as vals FROM dbx.testx where time between ('2016-09-01 00:00:00') and ('2016-09-03 23:59:59');"; ResultSet resultSetForSelect = st.executeQuery(selectStatement); String insertStatement = "INSERT INTO testy(" + "field1," + "field2)" + + String from result + "ON DUPLICATE KEY UPDATE field1 = VALUES(field1);"; <----field1 is a unique key but not primary # execute one time

I would say the answer is: you can't. (or at least: you shouldn't). This is not what Webpack is supposed to do. Webpack is a bundler, and it should not be used for other tasks (in this case: copying static files is another task). You should use a tool like Grunt og Gulp to do such tasks. It is very common to integrate webpack as a grunt task or as a gulp task. They both have other tasks useful for copying files like you described. grunt-contrib-copy or gulp-copy.

For other assets (not the index.html), you can just bundle them in with webpack (that is exactly what webpack is for). var image = require('assets/my_image.png'); But I assume your index.html needs to not be a part of the bundle, and therefore it is not a job for the bundler.

18948450 0 Filter a list and requesting data via ajax

im new to javascript and phonegap and im sitting here the whole day and try to solve this problem.

I have a list and i want to filter some data. And before i filter it, i want to download some data from a server and add it to the list. ( the list is local and if someone uses the search function, new data should pop up too).

The idea is that i create the list with jquery and use the listviewbeforefilter-event to download the data from a server and add it to the list. Then jquery should filter the list.

It works fine when i search filter for 2 chars.

But this doesnt work as expected when i search for more than 2 chars. I receive the correct data from the server and it will be added to my list but the there is no more filtering in my original list. So i see my original list + the loaded data. Also the console.log("second") is shown first and then console.log("first). Somehow jquery/phonegap skips the .then part and then comes back to it.

I tried to put the 3 lines ($ul.html( content );$ul.listview( "refresh" );$ul.trigger( "updatelayout");) below the second console.log and then the filter of my local data works but the data from the server wont be shown.

I hope someone can help me with this weird problem.

Heres my code for the listviewbeforefilter-event:

 <html> <head> <meta charset="utf-8"> <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" /> <title>Listview Autocomplete - jQuery Mobile Demos</title> <link rel="stylesheet" href="css/jquery.mobile-1.3.2.min.css" /> <script src="cordova.js"></script> <script src="js/jquery-2.0.3.min.js"></script> <script src="js/jquery.mobile-1.3.2.min.js"></script> <script> $( document ).on( "pageinit", "#myPage", function() { $( "#autocomplete" ).on( "listviewbeforefilter", function ( e, data ) { // this is a second list which is a backup. It is needed because after each search the original list is flooded with old entries. var content = document.getElementById("autocomplete2").innerHTML; var requestdata = ""; var $ul = $( this ); $input = $( data.input ), value = $input.val(); // ajax call returns cities with at least 3 characters if ( value && value.length > 2 ) { $.ajax({ url: "http://gd.geobytes.com/AutoCompleteCity", dataType: "jsonp", crossDomain: true, data: { q: $input.val() } }) // The response is saved in html which i append to the original content .then( function ( response ) { var html = ""; console.log("first"); $.each( response, function ( i, val ) { html += "<li>" + val + "</li>"; }); content = content + html; $ul.html( content ); $ul.listview( "refresh" ); $ul.trigger( "updatelayout"); }); console.log("second"); } }); }); </script>

and that is the body with the list:

 </head> <body> <div data-role="page" id="myPage"> <div data-role="header" data-theme="f"> <h1>Listview </h1> </div><!-- /header --> <div data-role="content"> <div class="content-primary"> <ul id = "autocomplete" data-role="listview" data-filter="true" data-filter-placeholder="Search people..." data-filter-theme="d"data-theme="d" data-divider-theme="d"> <li data-role="list-divider">A</li> <li><a href="index.html">Adam Kinkaid</a></li> <li><a href="index.html">Alex Wickerham</a></li> <li><a href="index.html">Avery Johnson</a></li> </ul> </div><!--/content-primary --> </div><!-- /content --> <script type="text/javascript" charset="utf-8"> $(function(){ $( "#autocomplete2" ).hide(); }); </script> <ul id = "autocomplete2" data-role="listview" data-filter-theme="d"data-theme="d" data-divider-theme="d"> <li data-role="list-divider">A</li> <li><a href="index.html">Adam Kinkaid</a></li> <li><a href="index.html">Alex Wickerham</a></li> <li><a href="index.html">Avery Johnson</a></li> </ul> </div><!-- /page --> </body> </html>

As far as I can tell, in your example you are converting the contents of the file to a string. But this is problematic because you actually throw away the encoding when you convert bytes to string. When the SAX parser converts the string to a byte array, it decides it will be UTF-8, but the prolog states that it is UTF-16 and so you have a problem.

Instead, when I use the StreamSource, it just automatically detects the fact that the file is encoded in UTF-16 LE from the BOM.

If you are not using java-7 or up and cannot use try-with-resources, then use the stream.close() as before.

31500093 0

Basically this code relies on a little trick: if you seed the SHA1PRNG for the SUN provider and Bouncy Castle provider before it is used then it will always generate the same stream of random bytes. This is not always the case for every provider though; other providers simply mix in the seed. In other words, they may use a pre-seeded PRNG. In that case the getRawKey method generates different keys for the encrypt and decrypt, which will result in a failure to decrypt.

Basically this horrible code snippet abuses the SHA1PRNG as a Key Derivation Fucntion or KDF. You should use a true KDF such as PBKDF2 if the input is a password or HKDF if the input is a key.

That code snippet should be removed. It has been copied from Android snippets, but I cannot find that site anymore.

It has nothing to do with the inner function being named or not.

In the first screenshot you're inspecting the out variable, which references a function returned but outer. That function has x in its closure scope.

In the second screenshot you're inspecting the outer variable, which references a named global function. In that code snippet you don't have any variable to reference the result or outer(3). If you assign that to a variable just like you do in the first example var out = outer(3) and put a breakpoint after that assignment, you'll be able to see out's closure scope. Alternatively, you can inspect that by adding a "watch expression" of outer(3) in the debugger without the need to modify your code.

8466589 0 Cannot print variables onto the screen

I want to print variables onto the screen of my game. I am using text boxes to display the variables. When I try update the text boxes, the text boxes are blank.

I use an EventListener to update the text boxes:

// Add the EventListener that updates the game HUD addEventListener(Event.ENTER_FRAME, updateHUD);

Here is the 'updateHUD()' function:

 public function updateHUD(event:Event) { txtHealth.text = String(player.pHealth); txtDarts.text = String(player.pAmmo); txtScore.text = String(player.pScore); }`

If I place txtScore.text = String("score"); within this code, not even "score" is printed. The Text Box is still blank.

I was talking with a friend about this. He said he had a similar issue in his project. His problem had to do with incorrect Text Box settings. The boxes I want to update are set to "Classic Text", "Dynamic Text," and "Singleline."

I have other text boxes that act as "labels." They are displayed just fine on the screen. But I do not try to change them.

Any help would be appreciated.

Thanks, Christian

keySet() does not create a new Set.

It simply offers a view of the keys in your map. It actually provides only a few operations which are iteration (with remove), size, emptiness, clear and contains. You cannot add an element to it otherwise it will throw an UnsupportedOperationException.

29667596 0 After high traffic Cassandra WriteTimeoutException

I'm experimenting with cassandra to use it for storing tracking data. I process get requests (300 req/sec) with tracking information through django with uwsgi on nginx. The django application writes to cassandra (single cluster with 3 RF) directly. For this im taking the cassandra-driver (2.5.0).

After restarting all relevant services the whole thing works for about two hours. Then the server goes down and produces a server error 500.

Currently i don't know where the bottleneck is. Syslog show normal I/O activity on my system also CPU is just used by 32%.

I'm working primarily with counters. My tables look like this:

CREATE TABLE rollup_hour_counter ( name text, player_id text, hour timestamp, "count" counter, PRIMARY KEY ((name, player_id), hour) )

My code to write into cassandra looks like this:

rows = session.execute('UPDATE rollup_hour_counter ' 'SET count = count + 1' 'WHERE player_id=\'%s\' AND hour=\'%s:00:00\' AND name = \'name\'' % (player_uuid, date_now_hour))

I did some research on the errors in the log files.

uwsgi logs show:

34317571 0 how to work around with fusion table styles limited to 5

I have a fusion table. I use the following javascript code to toggle 2 styles.

fusionTableLayer.setOptions({ styles: styles1 }); fusionTableLayer.setOptions({ styles: styles2 });

Problem is my style2 has more than 7 styles. But because of the limitation of fusiontable, the 6th and 7th styles doesn't work. How can work around this?

Try this,

on your blade something link below.

 <div class="col-xs-12 col-sm-12 col-md-6 col-lg-6"> <div class="form-group {{ $errors->has('name') ? 'has-error' : '' }} control-required"> {!! Form::label('title', 'Title') !!}<span class="mand_star"> *</span> {!! Form::text('title', isset($news->title) ? $news->title : \Input::old('title'), [ 'class' => 'form-control', 'placeholder' => 'News Title', 'required' => 'required' ]) !!} <span class="error_span"> {{ $errors->first('title') }}</span> </div> </div>

On your controller something like.

if ($validation->fails()) { return redirect()->route('your route path')->withErrors($validation)->withInput(); }

it works for all individual input fields also fills old data in that field.

hope it helps.

When no charset is defined in the content-type header of your HTTP request, resteasy assumes 'charset=US-ASCII'. See org.jboss.resteasy.plugins.providers.multipart.InputPart:

/** * If there is a content-type header without a charset parameter, charset=US-ASCII * is assumed. * <p> * This can be overwritten by setting a different String value in * {@link org.jboss.resteasy.spi.HttpRequest#setAttribute(String, Object)} * with this ("resteasy.provider.multipart.inputpart.defaultCharset") * String`enter code here` as key. It should be done in a * {@link org.jboss.resteasy.spi.interception.PreProcessInterceptor}. * </p> */

So, as a work-around you can do the following:

 @Provider @ServerInterceptor public class CharsetPreProcessInterceptor implements PreProcessInterceptor { @Override public ServerResponse preProcess(HttpRequest request, ResourceMethod method) throws Failure, WebApplicationException { request.setAttribute(InputPart.DEFAULT_CHARSET_PROPERTY, "charset=UTF-8"); return null; } }

28973645 0 How do the parameters in ruby '.each do' for-loops work?

What's confusing me in the code below is how the parameters state and abbrev match up with the keys and and the values of the hash? Or in other words, how is state matched up with 'oregon' and abbrev with 'OR' (if the parameters matched words in the hash, then I could understand that)

Are they matched up correctly because the first parameter is paired with the first value in the code block?

states = { 'Oregon' => 'OR', 'Florida' => 'FL', 'California' => 'CA', 'New York' => 'NY', 'Michigan' => 'MI' } states.each do |state, abbrev| puts "#{state} is abbreviated #{abbrev}" end

The output of this code:

Oregon is abbreviated OR Florida is abbreviated FL California is abbreviated CA New York is abbreviated NY Michigan is abbreviated MI

When you use the initializer list you can omit the (), when using a parameterless constructor. It does not matter with the new Cat() is inside the list or not.

Add changeHash: true from where you are redirecting. And then use 'history.back()' or 'history.go(-1)' from your current page. It will only take you 1 page back.

ViewPatterns is probably the way to go here. Your code doesn't work because you need to call viewl or viewr on your Seq first to get something of type ViewL or ViewR. ViewPatterns can handle that pretty nicely:

{-# LANGUAGE ViewPatterns #-} foo (S.viewl -> S.EmptyL) = ... -- empty on left foo (S.viewl -> (x S.:< xs)) = ... -- not empty on left

Which is equivalent to something like:

foo seq = case S.viewl seq of S.EmptyL -> ... (x S.:< xs) -> ...

8020748 0 IndicatingAjaxButton works only once

I have derived a class from IndicatingAjaxButton (which is the button to a form). But the IAjaxIndicatorAware does only work once, i.e. if the validation of the form fails I print feedback messages within the form. During the 1st request the "onProgress-Circle" is shown. But if I click on the button again (after I made the right input on the form), there is no "onProgress-Circle" anymore.

I took a look in the generated HTML: 1) Before the first click, there is a img tag, which gets displayed when the request is started 2) After the first request is processed, this img tag is removed.

This are the evaluation steps that are returned from the server:

<evaluate><![CDATA[var e = Wicket.$('previouse--ajax-indicator'); if (e != null && typeof(e.parentNode) != 'undefined') e.parentNode.removeChild(e);]]></evaluate>

This I guess leads to removing all childs from the button, also the img tag. Is this a bug or do I use the button in a wrong way?

I use Wicket 1.5

29360114 1 Django model filter compare month fail

Suppose I have this model:

id=15, username='yhbohh' last_login='2015-03-31 10:57:18'

I would like to get a number count of objects with last login of month=3.

I tried in shell,

User.objects.filter(last_login__year=2015).count() # return 80 User.objects.filter(last_login__month=3).count() # return 0 User.objects.filter(last_login__day=31).count() # return 0

May I know why the last 2 queries return no records? I have searched from the other questions and notice than someone may suggest to use date range comparison to solve this problem. But I just wanna know the root cause of this unexpected result.

27536812 0 const-correctness in void methods and lambda 'trick'

I have a method that accepts a reference of an object as const, this method doesn't change anything of the method and the const indicates that, the thing is that this method also calls other method that is within the class and is void, doesn't accept any argument and is also virtual, meaning that the class that extends the base class can override the method BUT it needs to be const as well. Eg:

#include <iostream> class Boz { public: virtual void introduce() const = 0; }; class Foo { public: virtual void callable() const { // ... } void caller(const Boz& object) const { callable(); object.introduce(); } }; class Bar : public Boz { public: void introduce() const { std::cout << "Hi." << std::endl; } }; class Biz : public Foo { public: void callable() const { std::cout << "I'm being called before the introduce." << std::endl; } }; int main(void) { Biz biz; biz.caller(Bar()); return 0; }

The output would be:

I'm being called before the introduce. Hi.

As you can see callable must to be const in order to be called. If I change and do this:

class Biz : public Foo { public: void callable() { std::cout << "I'm being called before the introduce." << std::endl; } };

It will compile not errors are thrown but the callable method won't be called, but the virtual one as it's defined as const. It's quite obvious.

The trickiest part here:

class Foo { public: virtual void callable() { // ... } void caller(const Boz& object) const { auto trick = [&] () { callable(); }; trick(); object.introduce(); } }; class Biz : public Foo { public: void callable() { std::cout << "I'm being called before the introduce." << std::endl; } };

It works and the callable method is called. No errors like passing 'const ...' as 'this' argument.

What I'm trying to do is to call callable without the need of being const and the reason is simple: The method doesn't change anything, he don't have access to the object that is begin passed as argument on caller method then we assume that he doesn't have the need to be const but the compiler throws an error even that way. The real problem is that callable is virtual and classes can extend the base class, implement their own callable and try to call other methods but can't if it's not const as well.

What I want is pretty much that, is to know how can I call the virtual method without the need of being const (the reason is pretty much that, I'm kind forcing the users that extends the class and override the callable method to only call const methods and this is not what I want) and of course understand what happens with the lambda and why it works.

The -1 is because integers start at 0, but our counting starts at 1.

So, 2^32-1 is the maximum value for a 32-bit unsigned integer (32 binary digits). 2^32 is the number of possible values.

To simplify why, look at decimal. 10^2-1 is the maximum value of a 2-digit decimal number (99). Because our intuitive human counting starts at 1, but integers are 0-based, 10^2 is the number of values (100).

I know about the the various ways to use the exception message (for instance by using str(var)).

For example, if the input is bla which would cause a ValueError exception, print(var) outputs invalid literal for int() with base 10: 'bla', which is not really usable.

However, I created this program that should use str(var) to my advantage:

try: x = int(input()) except ValueError as var: s = str(var) print('Exception message: ' +s) i=0 while (s[i] != '\''): i = i+1 i = i+1 print_str = '' while (s[i] != '\''): print_str = print_str + str(s[i]) i++ print('print_str = ' + print_str)

This program would probably work after a few changes..

So my question is: Is there a more direct way to get the 'x' string value?

Try storing it as bytes:

UUID uuid = UUID.randomUUID(); byte[] uuidBytes = new byte[16]; ByteBuffer.wrap(uuidBytes) .order(ByteOrder.BIG_ENDIAN) .putLong(uuid.getMostSignificantBits()) .putLong(uuid.getLeastSignificantBits()); con.createQuery("INSERT INTO TestTable(ID, Name) VALUES(:id, :name)") .addParameter("id", uuidBytes) .addParameter("name", "test1").executeUpdate();

A bit of an explanation: your table is using BINARY(16), so serializing UUID as its raw bytes is a really straightforward approach. UUIDs are essentially 128-bit ints with a few reserved bits, so this code writes it out as a big-endian 128-bit int. The ByteBuffer is just an easy way to turn two longs into a byte array.

Now in practice, all the conversion effort and headaches won't be worth the 20 bytes you save per row.

Pointing i to a different object does not mutate the (original) object. This is not special to primitives. Say you have a List<List<Object>> or a List<List<String>>:

 List<List<String>> wrapper = new ArrayList<List<String>>(); List<String> l1 = new ArrayList<String>(); wrapper.add(l1); l1 = new ArrayList<String>(); l1.add("hello"); for(List<String> list : wrapper) { for(String string : list) { System.out.println(string); } }

If you now iterate over wrapper you find it contains 1 empty list. This is equivalent to your first example. Your second example looks like:

 List<List<String>> wrapper = new ArrayList<List<String>>(); List<String> l1 = new ArrayList<String>(); wrapper.add(l1); l1.add("hello"); for(List<String> list : wrapper) { for(String string : list) { System.out.println(string); } }

In this case the wrapper now contains 1 list with one value in it.

137060 0 Too many "pattern suffixes" - design smell?

I just found myself creating a class called "InstructionBuilderFactoryMapFactory". That's 4 "pattern suffixes" on one class. It immediately reminded me of this:

http://www.jroller.com/landers/entry/the_design_pattern_facade_pattern

Is this a design smell? Should I impose a limit on this number?

I know some programmers have similar rules for other things (e.g. no more than N levels of pointer indirection in C.)

All the classes seem necessary to me. I have a (fixed) map from strings to factories - something I do all the time. The list is getting long and I want to move it out of the constructor of the class that uses the builders (that are created by the factories that are obtained from the map...) And as usual I'm avoiding Singletons.

ah vb6 :) it's been a long time....

basically, you can't debug .NET code within VB6 IDE.

However, nothing stops you from creating a .NET test project to unit test the .NET dll. And that's what you should have done prior to reference it in VB6.

If you need to track down a specific issue, another way you can use is to write debugging infos to a file/database/event view/... when the dll is in debug mode, like which functions were called, parameters, stack trace...

Just for debugging purposes, try setting the backgroundColor of aLabel and aReflectionView to see where they're being placed.

aLabel.backgroundColor = [UIColor redColor]; aReflectionView.backgroundColor = [UIColor blueColor];

You should see that the aReflectionView is properly centered within its superview, but the aLabel, contained within it, is not. Why not? Because of this line:

UILabel *aLabel = [[UILabel alloc]initWithFrame:CGRectMake(((self.view.bounds.size.width / 2) - 150), 0, 300, 90)];

Since aLabel is contained within aReflectionView, it should be centered within the aReflectionView bounds, not the bounds of self.view. Scroll right to see the change:

UILabel *aLabel = [[UILabel alloc]initWithFrame:CGRectMake(((aReflectionView.bounds.size.width / 2) - 150), 0, 300, 90)];

For your purposes, it may be better to make aLabel simply fill aReflectionView:

UILabel *aLabel = [[UILabel alloc]initWithFrame:aReflectionView.bounds];

30047256 0 Mongodb, time difference between two checkpoints

I m actually developping an application using a Mongodb database. Actually, there's a system with "checkpoints", a user scan an NFC tag when he enters in a place, and scan this same tag to leave this place.

So, in my database, I have something like :

{ "enterDate":"the-date-iso-string-formatted", "leaveDate":"the-date-iso-string-formatted" }

Actually, I need to detect what is the time between two different end point. I mean, how much time the user takes to travel from one place, to the next one.

In fact it corresponds to the avg of all the

endPoint[1].enterDate- endPoint[0].leaveDate

What is the best way, or the quickest way to manage this ?

Thanks for advance

25737201 0 Six degrees of Kevin Bacon

There are a couple other posts about degrees of Kevin Bacon, and the answers on those posts are similar to what I came up with myself before looking it up. But it's evident that I'm still doing something wrong from the results I get and the way the performance of my query falls off as I increase the degree of separation from Kevin Bacon.

Here's my query to find all actors with one degree of Kevin Bacon:

match p=(:Person {name:"Kevin Bacon"})-[:ACTED_IN*..2]-(:Person) return p

If I understand correctly, that's equivalent to this:

match p=(:Person {name:"Kevin Bacon"})-[:ACTED_IN]->()<-[:ACTED_IN]-(:Person) return p

And indeed, both of these queries return the same number of rows. But if I modify the first version of the query and increase the path length to 6 (i.e., three degrees of Kevin Bacon) it returns 978 rows. There are only 133 Person nodes in the database, so I would expect it to return at most 133 rows.

My guess is that it's returning multiple paths to some of the Person nodes. How do I tell it to return only the shortest path to each? Basically, I want to perform a single depth-first or breadth-first search. I think it might involve WITH, but I don't really understand how to use that yet.

37420319 0 Accessing Atlas, individual, and embedded resources/images easily

Basically, I have a bunch of images that I can combine into a single image(an atlas) or use individually. For testing/designing purposes, I would like to keep all the images separate but for release they should all be combine into the atlas(for non-embeddable compilers) or embedded.

e.g., suppose I have 100 sprites. I can create a single atlas for them, use them all individually unembedded, or embed the atlas, or embed all the image.

I'd like to start out with the individual+unembedded case for development then move to the embedded atlas case or embedded individual case(but I think this is probably not as good as the embedded atlas).

Is there an easy way to set this up in C# so the transition will be minimal?

The problem with the embedded atlas is that I would have to convert loading images(simple Image.FromFile into extracting images from the atlas).

Just curious what would be a good approach to remove the need for rewriting a lot of code in the future when the switch is made.

I could have something like Image.FromAtlas that essentially figures out the details(uses FromFile if we are in "development mode" or extracts the image from the atlas if in production... I think the embedded case would be rather trivial to implement).

What do you think? Thanks.

10181990 0 jQuery selector, .hide() UL and LI elements

I am trying to have a category index of expandable/colapsable elements, and when the user clicks a category it is rebuilt with an id of 'catSel'.

The problem is when the user clicks an <li> and the 'catSel' id is added to it, it will still be affected by the .hide(); and I don't want it to be. I should note that I have it working if the user clicks a <ul> element it will not be affected by the .hide();

What I really want is that if a <ul> or any of its <li> elements have the id of 'catSel' that that <ul> will not be affected by the .hide();

Here is the code and a sample link, you can see how the <ul> is not expanded but one of its <li> children has an id of 'catSel'

EDIT: Sorry for the bad explanation, I still can't explain it very well but I want it so that if a <ul> or one of its child <li> elements has an id="catSel" that it will not be affected by $('ul.catList:not(.level-0) li:has(ul):not(#catSel)').children('ul').hide();.

UPDATE:

I added this code:

// If an elementwith its id="catSel" show all of its parents and also update the parents class $('#catSel').parents().show(); $('#catSel').parents().removeClass('plusimageapply'); $('#catSel').parents().addClass('minusimageapply');

and now it seems to be working how I wanted it to. Thank you everyone who tried to make sense of my question and help me out.

691194 0 Why is my implementation of C++ map not storing values?

I have a class called ImageMatrix, which implements the C++ map in a recursive fashion; the end result is that I have a 3 dimensional array.

typedef uint32_t VUInt32; typedef int32_t VInt32; class ImageMatrix { public: ImageMatrixRow operator[](VInt32 rowIndex) private: ImageMatrixRowMap rows; }; typedef std::map <VUInt32, VInt32> ImageMatrixChannelMap; class ImageMatrixColumn { public: VInt32 &operator[](VUInt32 channelIndex); private: ImageMatrixChannelMap channels; }; typedef std::map<VUInt32, ImageMatrixColumn> ImageMatrixColumnMap; class ImageMatrixRow { public: ImageMatrixColumn operator[](VUInt32 columnIndex); private: ImageMatrixColumnMap columns; }; typedef std::map<VUInt32, ImageMatrixRow> ImageMatrixRowMap;

Each operator simply returns a map-wrapper class within, like so:

ImageMatrixRow ImageMatrix::operator[](VInt32 rowIndex) { return rows[rowIndex]; } ImageMatrixColumn ImageMatrixRow::operator[](VUInt32 columnIndex) { return columns[columnIndex]; } VInt32 &ImageMatrixColumn::operator[](VUInt32 channelIndex) { return channels[channelIndex]; }

Basically, when I set the value as say 100, and test the value to cout, it shows as 0, and not the number to which I had set it.

for (VUInt32 a = 0; a < GetRowCount(); a++) { for (VUInt32 b = 0; b < GetColumnCount(); b++) { for (VUInt32 c = 0; c < GetChannelCount(); c++) { VInt32 value = 100; matrix[a][b][c] = value; VInt32 test = matrix[a][b][c]; // pixel = 100, test = 0 - why? cout << pixel << "/" << test << endl; } } }

Note: I've altered the original code for this example so that it takes up less space, so some syntax errors may occur (please don't point them out).

The Implicit Grant Type is being seen by many (lucadegasperi's oauth2-server-laravel among others) as the least secure of the OAuth2 grant types, therefore I recommend you to use JWT for your service website instead.

To integrate JWT with Laravel, have a look at the following library. It works very well, and is also supported by the popular out-of-the-box API package Dingo for Laravel (https://github.com/dingo/api):

https://github.com/tymondesigns/jwt-auth

As for the app(s), if the app is a first-party app, go for the OAuth2 password grant as mentioned by Florens Morselli. If it is third-party app, use the authorization code grant instead.

With no client driver at all, you can simply execute the psql command-line then read and process its output. This is particularly useful when invoking it as psql -qAt and/or using \copy.

Otherwise you must have some kind of client driver. Powershell has no built-in support code for the PostgreSQL protocol, so it therefore cannot communicate with PostgreSQL without some kind of client driver. nPgSQL would be the most obvious choice since it integrates well in .NET and is composed only of .NET assemblies. You could probably bundle nPgSQL up as a Powershell extension... but as usual, someone already did that.

Otherwise you probably want to install psqlODBC, which is a simple msiexec to install then usable using the usual ODBC support.

(The only reason Powershell can talk to MS SQL without installing additional drivers is that drivers for MS SQL are built in).

25030459 0 Convert JObject to type at runtime

I am writing a simple event dispatcher where my events come in as objects with the clr type name and the json object representing the original event (after the byte[] has been processed into the jobject) that was fired. I'm using GetEventStore if anyone wants to know the specifics.

I want to take that clr type to do 2 things:

find the classes that implements IHandles and
call Consume(clr type) on that class

I have managed to get part 1 working fine with the following code:

 var processedEvent = ProcessRawEvent(@event); var t = Type.GetType(processedEvent.EventClrTypeName); var type = typeof(IHandlesEvent<>).MakeGenericType(t); var allHandlers = container.ResolveAll(type); foreach (var allHandler in allHandlers) { var method = allHandler.GetType().GetMethod("Consume", new[] { t }); method.Invoke(allHandler, new[] { processedEvent.Data }); }

ATM the issue is that processedEvent.Data is a JObject - I know the type of processedEvent.Data because I have t defined above it.

How can I parse that JObject into type t without doing any nasty switching on the type name?

The & should be HTML encoded as &, and : and / in the values should be URL encoded as %3A and %2F:

href="http://secure.hostgator.com/~affiliat/cgi-bin/affiliates/clickthru.cgi?id=vpspricing&amp;page=http%3A%2F%2Fwww.hostgator.com%2Fvps-hosting"

Breakdown: First the values vpspricing and http://www.hostgator.com/vps-hosting are URL encoded into vpspricing (no change) and http%3A%2F%2Fwww.hostgator.com%2Fvps-hosting so that you can put them in the URL. Then you HTML encode the entire URL so that you can put it in the attribute in the HTML code. It's only the & character that needs to be HTML encoded in this case.

Instead of

static int _difficulty;

type this into your GameManager.h

@property int difficulty;

You don't have to write the Setter and Getter by yourself, the property-statement do this for you. The Getter/Setter is stored in the instance of GameManager you use. So get the instance of you GameManager and there you set like this:

[MyGameManagerInstance setDifficulty:0];

and get like

[MyGameManagerInstance difficulty];

Due to the fact that the difficulty-property is in the .h file, it's part of the Class's API which you can access from other ViewController or Classes.

EDIT: Like you said, you could do this also with the NSUserDefaults. Just put it in like this:

[[NSUserDefaults standardUserDefaults] setInteger:1 forKey:@"Difficulty"];

and get it like this:

int myInt = [[NSUserDefaults standardUserDefaults] integerForKey:@"Difficulty"];

39705323 0 Call different method depending on Bool without if-statement in Swift

Is it possible to call one or another method depending a Bool value? I wish to do this:

var isLocked: Bool { didSet { // This is not Swift but indicates what I'm looking for. self.activityIndicator.(isLocked ? startAnimating() : stopAnimating()) } }

I'm looking to do this using existing Swift 2 (or 3) language features; without class extensions.

Possibly a duplicate, but couldn't find.

I assume pageTabPanel isn't defined at the time you trigger the handler. Try to remove the var keyword in front of "var pageTabPanel =" to make it a global variable.

If that works, it's a scope/variable issue. The better solution is to give the tabpanel an id and call Ext.getCmp('tabpanelid').render('contentpanel') in your renderPageTabs method.

Hope that helps.

After investigation it seems that getting a 403 error happens if the account that is set in .setServiceAccountUser("admin.of.my@domain.com") is not a "Super Admin" of the domain.

However in the case above "admin.of.my@domain.com" is indeed a Super Admin of the domain. Also the code works well with any other Super Admin of the domain which leads to believe that there is something wrong with the account "admin.of.my@domain.com" in particular.

If this happens to anyone else - a.k.a. an account set as "Super Admin" which does not work to access Admins-only APIs through Service Accounts - make sure you let us know in the comments below and we'll investigate further if this impacts lots of people.

You should not be storing numeric data as a string but if you do, then you will need to cast() it to apply a SUM() aggregate to it:

SELECT SUM(CAST(yourcolumn AS DECIMAL(10, 2))) FROM yourtable

So your query will be:

select sum(cast(qty as DECIMAL(10, 2))) from inventory i where i.refDocNum = 485 and i.refApp = 'WO' and i.type in (20, 21)

I suppose it is mandatory to use regex in your assignment... if not i would go for an xml parser...

But if YES I suggest you have a go with Reg Ex buddy

RegexBuddy makes it easier than ever for you to create regular expressions that do what you intend, without any guesswork. Still, you need to test your regex patterns to be 100% sure that they match what you want, and don't match what you don't want.

Is it a high resolution image? which you are trying to load,

13168742 0

Gibberish,

Try the ImageMapster jQuery plugin, which acts on image maps to offer (at v1.2.6) the following features :

Highlight and select areas
Cool effects by using an alternate image
Bind the image map to an external list
Show floating tooltips for areas or area groups
Grouping and exclusion masks to create complex functionality
Automatic scaling of imagemaps to any display size, even while active

The feature you need is the last one listed.

I've not used ImageMapster myself, but the demos are very impressive and indicative of a well written plugin.

32072930 0 Scrollable Line Chart

Am trying to use the ios-charts library based off the MPAndroidCharts; however am having some trouble getting a scrollable graph to work.

By scrollable I mean that I try to show only a portion of the data of the line and that you can scroll horizontally to see more results. E.g I have 30 results and I only show 10 at a time and then scroll horizontally to see more.

Have come up with an approximation by using the method

[self.containerView setVisibleXRangeWithMinXRange:24.0f maxXRange:24.0f];

However this seems to make the scrolling kind of jittery as it keeps on redrawing.

Am looking for an ios-charts example and clarification on methods to see whether I am on the right track or not.

34910745 0 What are the best practices for single-instanced classes in java?

In my program I have a menu system in which I have a separate class for each menu, for example MainMenu would be a separate class. But the class is only supposed to be instanced once, and after I instance it, it is saved in a list which is all is used for after that. Should I use another solution than a separate class? Or should I make the constructor private and then make a private instance inside the class? I feel like this violates OOP, but I don't see another solution.

The best way would be through feature detection in the browser. Since there is not a standard way of detecting touch through CSS. I would just do this JavaScript:

if ('ontouchstart' in document) { // Bring in the necessary CSS optimized for touch }

15914069 0

Well, it seems like the main issue was with your css. When a mouseover event was triggered, the modalMask element was shown. The problem however was that you placed it on top of everything else with:

position: absolute; ... width: 100%; height: 100%; ... z-index: 1000;

This means that you had an invisible layer blocking access to the links, and that's why there was no reaction after the first event.

While troubleshooting, i cleaned up the code for you at: http://jsfiddle.net/Z4ZGZ/18/

The 'close' button doesn't work in the fiddle, but it worked for me locally when i included the script file at the bottom of the body element.

why use [yield]? Apart from it being slightly less code, what's it do for me?

Sometimes it is useful, sometimes not. If the entire set of data must be examined and returned then there is not going to be any benefit in using yield because all it did was introduce overhead.

When yield really shines is when only a partial set is returned. I think the best example is sorting. Assume you have a list of objects containing a date and a dollar amount from this year and you would like to see the first handful (5) records of the year.

In order to accomplish this, the list must be sorted ascending by date, and then have the first 5 taken. If this was done without yield, the entire list would have to be sorted, right up to making sure the last two dates were in order.

However, with yield, once the first 5 items have been established the sorting stops and the results are available. This can save a large amount of time.

The sort of background processing you're looking to do is not possible with push notification.

Push notification allows you to notify the user of something. An example would be a Twitter client that sends a notification when the user receives a direct message on Twitter.

Push notification can not react to things happening on the iPhone when the app is not running. Instead, it depends on you having a server that determines when to send a notification and then sends one.

I'm not seeing any need for background processing in your application. If you store the user's initial location, the next time the app loads you can get their location and calculate the distance between the two. If you're looking for the route travelled, you're out of luck unless you make a deal with AT&T like Loopt just did.

I think your permission should be filtered by the role. Something like this :

var rolePermissions = new HashSet<int>(tDbContext.RoleDetail.Where(rd => rd.RoleId == role.RoleID).Select(rd => rd.PermissionId));

Your passing the role to your function but don't even use it : PopulateAssignedPermissionData(Role role). If i understand properly the code, now the allPermission and the rolePermissions are the same.

There's no "property by index" feature, but one approach that would make consumption easier would be to build an indexer on the class and encapsulate the switch statement there. Maybe something like this:

public class Plan { public int this[int index] { get { switch (index) { case 1: return this.a; ... } } set { switch (index) { case 1: this.a = value; ... } } } }

So, now using it looks like this:

planObject[i] = 100;

Now, in your case it looks like you have an additional need because you have a key (the index) and a value (e.g. 100), so you need to store your keys and values in a Dictionary. So, in your class that uses Plan create a private field:

private Dictionary<int, int> _values = new Dictionary<int, int> { { 1, 100 }, { 2, 200 }, ... }

To use the dictionary you'd do something like this:

planObject[i] = _values[i];

UPDATE: if you can't change the class Plan then you'll need to do something like this. First you need a map from index to property name:

private Dictionary<int, string> _properties = new Dictionary<int, string> { { 1, "a" }, { 2, "b" }, ... }

and next you'll need to set that property:

var t = planObject.GetType(); var p = t.GetProperty(_properties[i]); if (p != null) { p.SetValue(planObject, 100); }

You are right that generator expressions would have been the right choice - especially in multi-configuration environments - but if a certain command or property does not support them, you can't trick them into working.

But there are alternatives:

Setting ARCHIVE_OUTPUT_DIRECTORY Property

You could slightly change your "I guess I am meant to" strategy and place your library outputs you want to merge into a path of your own choosing. The following example is for a multi-configuration environment like Visual Studio:

add_library(lib1 STATIC bar.cc) set_target_properties(lib1 PROPERTIES ARCHIVE_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/Libs") file(WRITE dummy.cc "") add_library(merged STATIC dummy.cc) add_dependencies(merged lib1) set_target_properties( merged PROPERTIES STATIC_LIBRARY_FLAGS_DEBUG "${CMAKE_BINARY_DIR}/Libs/Debug/lib1.lib" STATIC_LIBRARY_FLAGS_RELEASE "${CMAKE_BINARY_DIR}/Libs/Release/lib1.lib" )

Using OBJECT Libraries

Or you can work with OBJECT libraries as intermediate grouping targets to prevent having to trick CMake into building your merged library:

add_library(lib1 OBJECT bar.cc) add_library(lib2 OBJECT foo.cc) add_library(merged $<TARGET_OBJECTS:lib1> $<TARGET_OBJECTS:lib2>)

I personally prefer the later.

If possible, it is better to re-factor your code to avoid putting the thread to sleep.

Try using ICollectionViews in combination with IsSynchronizedWithCurrentItem property when handling lists / ObservableCollection in Xaml. The ICollectionView in the viewmodel can handle all the things needed, e.g. sorting, filtering, keeping track of selections and states.

Xaml:

<Window x:Class="ComboBoxBinding.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition /> </Grid.ColumnDefinitions> <ListBox Grid.Column="0" ItemsSource="{Binding Reports}" DisplayMemberPath="Name" IsSynchronizedWithCurrentItem="True" /> <ComboBox Grid.Column="1" ItemsSource="{Binding CurrentReport.Performances}" DisplayMemberPath="Name" IsSynchronizedWithCurrentItem="True" /> </Grid> </Window>

ViewModel:

public class ViewModel : INotifyPropertyChanged { private readonly IReportService _reportService; private ObservableCollection<ReportViewModel> _reports = new ObservableCollection<ReportViewModel>(); private PerformanceViewModel _currentPerformance; private ReportViewModel _currentReport; public ObservableCollection<ReportViewModel> Reports { get { return _reports; } set { _reports = value; OnPropertyChanged("Reports");} } public ReportViewModel CurrentReport { get { return _currentReport; } set { _currentReport = value; OnPropertyChanged("CurrentReport");} } public PerformanceViewModel CurrentPerformance { get { return _currentPerformance; } set { _currentPerformance = value; OnPropertyChanged("CurrentPerformance");} } public ICollectionView ReportsView { get; private set; } public ICollectionView PerformancesView { get; private set; } public ViewModel(IReportService reportService) { if (reportService == null) throw new ArgumentNullException("reportService"); _reportService = reportService; var reports = _reportService.GetData(); Reports = new ObservableCollection<ReportViewModel>(reports); ReportsView = CollectionViewSource.GetDefaultView(Reports); ReportsView.SortDescriptions.Add(new SortDescription("Name", ListSortDirection.Ascending)); ReportsView.CurrentChanged += OnReportsChanged; ReportsView.MoveCurrentToFirst(); } private void OnReportsChanged(object sender, EventArgs e) { var selectedReport = ReportsView.CurrentItem as ReportViewModel; if (selectedReport == null) return; CurrentReport = selectedReport; if(PerformancesView != null) { PerformancesView.CurrentChanged -= OnPerformancesChanged; } PerformancesView = CollectionViewSource.GetDefaultView(CurrentReport.Performances); PerformancesView.SortDescriptions.Add(new SortDescription("Name", ListSortDirection.Ascending)); PerformancesView.CurrentChanged += OnPerformancesChanged; PerformancesView.MoveCurrentToFirst(); } private void OnPerformancesChanged(object sender, EventArgs e) { var selectedperformance = PerformancesView.CurrentItem as PerformanceViewModel; if (selectedperformance == null) return; CurrentPerformance = selectedperformance; } public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged(string propertyName) { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) handler(this, new PropertyChangedEventArgs(propertyName)); } }

16231375 0 WPF get parent of menuItem

I don't know how to get the parent of a menuItem? I searched all arround but can't get a good answer...

My XAML is:

<DockPanel> <Menu DockPanel.Dock="Right" SnapsToDevicePixels="True" Margin="2,0,0,0"> <MenuItem Header="Devices"> <local:MenuItemWithRadioButton x:Name="MenuItemVideoDevices" Header="Video"> </local:MenuItemWithRadioButton> <local:MenuItemWithRadioButton x:Name="MenuItemAudioDevices" Header="Audio"> </local:MenuItemWithRadioButton> </MenuItem> </Menu> </DockPanel> private void MenuItemWithRadioButtons_Click(object sender, System.Windows.RoutedEventArgs e) { MenuItem mi = sender as MenuItem; if (mi != null) { RadioButton rb = mi.Icon as RadioButton; if (rb != null) { rb.IsChecked = true; } //Here I want to get the parent menuItem } }

In the code, when I click the submenuItem like "MenuItemVideoDevices", an event process function is triggered, but I don't know how to get the menuItem "Video" in this function.

Anyone knows?

12977334 0 Multithreading and passing data to new threads

I have some issues with an application I'm coding. It's job is to solve a maze using threads. One thread begins, and for each bifurcation it calls a static method in another class, passing parameters that the other thread needs, and then starts threads for each path. My outputs are all messed up, and I'm not sure if it's a Multithreading problem or maybe a problem with the references. Here's some of the code (Each thread is given a new instance of an Explorer class):

This is the Run() method for each thread:

public void Explore() { while (ImDone == false) { Move(); if (ActualPosition[0] != Labyrinth.ExitPoint[0] || ActualPosition[1] != Labyrinth.ExitPoint[1]) //I'm not at the end.. continue; PrintMyStatus(); //Print in the console my parents and my complete route.. break; }

This is the Move() method:

List<int[]> validPaths = CheckSurroundings(); //returns a list of paths switch (validPaths.Count) { case 0: ImDone = true; //No more routes available break; case 1: MarkMyPosition(validPaths); //Change internal variables to the only new path break; default: lock(this) //As this involves thread creating I locked it.. { //Creating deep copies of my "History" so my childs can have them.. List<int[]> DCValidPaths = DeepCopy(validPaths); List<string> DCMyParents = DeepCopy(MyParents); string[,] DCMyExplorationMap = DeepCopy(MyExplorationMap); List<int[]> DCMyPositions = DeepCopy(MyPositions); foreach (var path in validPaths) { DCMyParents.Add(Thread.CurrentThread.Name); //Adding myself as a parent ExplorationManager.ExplorerMaker( DCValidPaths, DCMyParents, DCMyExplorationMap, DCMyPositions, ID); //Threads are created in the static class } } break; }

My DeepCopy() method is using is the one in the accepted answer of this question. Any other info needed I'll be more than happy to provide in order to solve the problem. Thanks in advance for your help.

EDITS: My problem consists basically in: I'm having an OutOfMemoryException in the Thread.Start() clause and the Path displayed by the threads contain corrupted data (incorrect positions). I tested the CheckSurroundings() method and by far only returns correct positions (The labyrinth is contained in a two-dimensional string array).

This is the constructor of the Explorer class:

public Explorer(List<string> myParents, int[] actualPosition, string[,] myExplorationMap, List<int[]> myPositions, int ID) { //Here I pass the data specified in Move(); MyParents = myParents; ActualPosition = actualPosition; MyExplorationMap = myExplorationMap; MyPositions = myPositions; this.ID = ID + 1; //An ID for reference //Marking position in my map with "1" so I know I've been here already, //and adding the position given to my list of positions MyExplorationMap[ActualPosition[0], ActualPosition[1]] = "1"; MyPositions.Add(DeepCopy(ActualPosition)); }

And this is the class creating the threads:

public static class ExplorationManager { public static void ExplorerMaker(List<int[]> validPaths, List<string> myParents, string[,] myExplorationMap, List<int[]> myPositions, int ID) { foreach (var thread in validPaths.Select (path => new Explorer(myParents, path, myExplorationMap, myPositions,ID)). Select(explorer => new Thread(explorer.Explore))) { thread.Name = "Thread of " + ID + " generation"; thread.Start(); //For each Path in Valid paths, create a new instance of Explorer and assign a thread to it. } } }

And the method returning the ValidPaths

 private List<int[]> CheckSurroundings() { var validPaths = new List<int[]>(); var posX = ActualPosition[0]; var posY = ActualPosition[1]; for (var dx = -1; dx <= 1; dx++) { if (dx == 0 || (posX + dx) < 0 || (posX + dx) >= Labyrinth.Size || MyExplorationMap[posX + dx, posY] == "1") continue; var tempPos = new int[2]; tempPos[0] = posX + dx; tempPos[1] = posY; validPaths.Add(tempPos); } for (var dy = -1; dy <= 1; dy++) { if (dy == 0 || (posY + dy) < 0 || (posY + dy) >= Labyrinth.Size || MyExplorationMap[posX, posY + dy] == "1") continue; var tempPos = new int[2]; tempPos[0] = posX; tempPos[1] = posY + dy; validPaths.Add(tempPos); } //This method checks up, down, left, right and returns the posible routes as `int[]` for each one return validPaths; }

CheckSurroundings uses the deep copy passed to the child (via the constructor) to validate the routes he can take. It is NOT intended to alterate the parent's copy, because he is now in ANOTHER path of the labyrinth. The child only needs the information updated (passed via the constructor) UNTIL the point they "separate". And also EACH child must be independent from the other childs. That's what I'm trying to do. But I'm not sure what's wrong, maybe concurrency problem? Please help. If you need anything else let me know. –

It's not necessary or even mandatory. But is it smart? Yes it is. Android Studio with Gradle and Maven are soooo powerful, that you are losing so much time using Eclipse.

Of course, you will have to pass all these painful steps, like we all did. What is Gradle? What is Maven? How do I import library? Where is my code? Why my Manifest does not work? And so on...

so I strongly advise you find a week of your time and learn new IDE by fixing all those things that will arise when you do conversion.

But in the end, you can still use Eclipse or IntelliJ IDEA the old way and leave learning to some other time.

35525496 0 How does one add a partial index checking for NULL to a JSON column on Postgres?

I've got a json column called data on Postgres, and I'd like to add a partial index that applies only to rows where this column is null - I basically need to find all the rows where data is null so I can put some data into them.

Trying to add an index gives an error about missing operator classes, though, because we can't index json types with a btree index. But I'm not trying to index a specific property either, for me to use data->>property. How can I index just the rows which have a json null in them?

Edit: The jsonb suggestion would work, but I'm stuck on 9.3 for this project.

Growing buttons in Excel is a fairly common issue, with several theories about why this happens, including the use of multiple monitors or using proportional fonts. I have yet to see a definitive answer about this, but there are several workarounds that may work for you.

Delete and re-create the buttons.
Programmatically set the height and width of the buttons when the workbook is opened and when a button is clicked.
Select the button with another object or two on the sheet and group them.
Don't use them at all.

My personal choice is #4. As an alternative to buttons, I either use hyperlinks or shapes with macros assigned to them.

Because when you call document.write the first time, it removes all links from the DOM. It replaces the entire innerHTML of document.body with "Hello: ".

You should never use document.write anyway.

I see a few pitfalls in your code, there are a few places where things can go wrong:

First, use of regular statements. Use prepared statements so you won't have problems with SQL injection.

Instead of

statement = connection.createStatement();

use

statement = connection.prepareStatement(String sql);

With this, your query becomes

"select distinct group_name From group_members where username= ?"

and you set username with

 statement.setString(1, username);

Next, I don't like use of your myDB class. What if results is null? You're not doing any error checking for that in your public List<InterestGroup> getGroups() method.

public void sendQuery(String query) seems to me like it shouldn't be void, but it should return a ResultSet. Also, search on the net for proper ways to do JDBC exception handling.

Also, this line:

new InterestGroup(results.getString("group_name"), myDB)

Why do you have myDB as a parameter?

I'd suggest adding more System.out.println statements in your code so you can see where things can go wrong.

29120225 0 VoltDB - decimal values have too many zeroes

Where the file 'tryMe.env' only consists of 1 line like so:

My wanted result is:

20443262 0 "A reference may be bound only to an object", why is "const int &ref = 3;" valid?

I am just starting learning c++. I found an advice on Internet: "Learn with a good book, it is better than videos on youtube." So as I am motivated and I have time I learn with c++ Primer 5th Ed.

In this book, they say: Note: "A reference is not an object. Instead, a reference is just another name for an already existing object."

and: "a reference may be bound only to an object, not to a literal or to the result of a more general expression"

I understand:

int i = 3; int &ri = i; // is valid: ri is a new name for i int &ri2 = 2; // is not valid: 2 is not an object

Then I don't understand why:

const int &ri3 = 2; // is valid

They write: "It can be easier to understand complicated pointer or reference declarations if you read them from right to left."

Ok, it is not very complicated. I understand: I declare a variable named ri3, it is a reference (a reference when & is after the type, an address when & is in an expression) to an object of type int and it is a constant.

I think it has already been explained many times but when I search on forums I find complicated (to me) answers to complicated problems, and I still don't understand.

Thank you for your help.

Give each route a name when you are defining it. Then inject $route into the controller, then have the controller publish it into the current scope. You can then bind the ng-switch to $route.current.name

26867796 0 Generic mobile tests with appium

I'm new to mobile testing , and currently I research for an automation framework for mobile testing. I've started to look into Appium, and created some tests for the demo app I've made (one for IOS and the other for Android). I've managed to write a test for each of the platforms , but I was wondering , how difficult it might be to write a one generic test which will be executed on the both platforms with minimum adjustments ?

Thanks

36256635 0 mongoose right usage of multiple databases?

I have multiple mongodb connections in my project:

// db.coffee conn1 = mongoose.createConnection "mongodb://192.168.1.193/test" conn2 = mongoose.createConnection "mongodb://92.168.1.81/position"

I have a model named PositionNoCity which belongs to conn2 and a model named A which belongs to conn1:

// a.coffee ASchema = new Schema { a: Number }, {collection: 'test'} mongoose.model 'A', ASchema // pos.coffee PositionNoCitySchema = new Schema { position_id: String, job_forward_stats: [{forward_position_num: Number, forward_position: String, forward_position_ratio: Number}], }, {collection: 'position_indicators_no_city'} mongoose.model 'PositionNoCity', PositionNoCitySchema

Now I want to use these models:

require './db' require './pos' require './a' mongoose = require 'mongoose' // I have to point out which connection to use here, but with index the code is very very bad A = mongoose.connections[1].model('A') PositionNoCity = mongoose.connections[2].model('PositionNoCity') PositionNoCity.findOne({position_id: "aaa"}).then(console.log).catch(console.log) A.findOne({'a': 1}).then(console.log).catch(console.log)

I have two questions:

I just connect 2 times, why 3 connections?
if I replace mongoose.connections[2].model with mongoose.model, I run failed. Anyway, mongoose.connections[2].model must be replaced somehow, so how to replace?

What are the fastest and the most flexible (applicable in most situations) ways to use VBOs?

I am developing an openGL application and i want it to get to the best performance, so i need someone to answer these questions. I read many questions and anwers but i guess there's to much information that i don't need which messes up my brain...

How many vbos should i use?
How should i create vbos?
How should i update vbos data, if the data size is not fixed?
How should i render vbos?
How should i deal with data in vbos that i don't want to render anymore?

The problems are caused by this:

 { (char) c = (int) c - 32 + key + 127; System.out.println(c); }

The (char) c = ...; is completely invalid syntax.

An assignment is supposed to look like this c = ...;.

If you want / need to do a type cast before assigning, the type cast belongs on the right hand side of the assignment operator; i.e. c = (char)(...).

Anyway, what you have written has cause the Java parser (in your IDE) to get thoroughly confused ... and spectacularly misdiagnose the error as an attempt to declare a constructor, it the wrong context.

Unfortunately, this happens sometimes ... though it is compiler dependent. The compiler was trying to be helpful, but the compiler / compiler writer "guessed wrong" about what you were trying to write at that point.

Then it appears that the compiler's syntax recovery has inserted a { symbol into its symbol stream in an attempt to fix things. The second error complains that there is no } to match the phantom { that it inserted. Again, it has guessed wrong.

But the root cause of this was your original syntax error.

For the record, the int cast in your original expression is not necessary. You could (and IMO should) write the assignment as this:

c = (char) (c - 32 + key + 127);

Explanation: in Java, the arithmetic operators always promote their operands to int (or long) before performing the operation, and the result is an int (or long). That means that your explicit cast of c to an int is going to happen anyway.

30178182 0 Collect RoutingError messages thrown

I've just put a rails 4 app into production, and I've noticed what look like a number of scripted attacks, mostly on urls that end with .php. They look like this:

I, [2015-05-11T22:03:01.715687 #18632] INFO -- : Started GET "/MyAdmin/scripts/setup.php" for 211.172.232.163 at 2015-05-11 22:03:01 +0100 F, [2015-05-11T22:03:01.719339 #18632] FATAL -- : ActionController::RoutingError (No route matches [GET] "/MyAdmin/scripts/setup.php"): actionpack (4.1.0) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'

I'd like to collect thee url from these RoutingError messages, mostly so I can set up routes for them, probably to simply render nothing.

I'd also like to redirect to a site which might keep script runners busy.

Anyway, here's the question. Is there any way I can intercept ActionController::RoutingError to run some code?

Bonus question: Does anyone know if there's actually a lot of php apps out there which can be broken into with urls like the one above?

33097912 0 Select items from one ListBox into another

I have a two ListBoxes listbox1 and listbox2. I want to get all the duplicate items in ListBox1 that i'd search in a TextBox and put in into ListBox2 and when all the duplicate item's that i'd search is in ListBox2 its automatically count please help me.

For example, items in ListBox1

DOG DOG DOG CAT CAT

When I type DOG in TextBox all the DOG in ListBox1 will be copied to ListBox2. How can I do it?

I tried this

Dim check As Boolean For Each item In ListBox1.Items check = ListBox1.FindStringExact(item) ListBox2.Items.Add(item) Next

i also try this but its wrong it count's the line before the exact word that i'd search. for example DOG DOG DOG CAT CAT i'd search CAT in textbox the output in listbox2 is 3 here's my code :

Dim check As String

 check = ListBox1.FindStringExact(TextBox1.Text) ListBox2.Items.Add(check)

In order to compute the rmse it is neccessary to have a maximum of 1 y value per x value, mathematically speaking a "function". You can plot later again the way your sketch shows it. But for the computation: rotate by 90 degree.

For the optimization, you need an initiall guess (your Alpha), which is not defined. However, with some minor changes in the code below, one can get the optimal parameters. Also it might be better readable. The plot is shown below.

plot(r, XMean ,'ko', 'markerfacecolor', 'black') % // need a "function" (max 1y value for 1x-value) Eqn = @(par, x) par(1).*( 1 - ( (par(2) - x) / par(3) ).^2 ); par0 = [1, 1, 1]; % // an initial guess as start for optimization par_fit = nlinfit(r, XMean, Eqn, par0 ); % // optimize hold on r_fit = linspace(min(r), max(r)); % // more points for smoother curve plot(r_fit, Eqn(par_fit, r_fit), 'r')

enter image description here The optimal parameters i get returned are

par_fit = 0.1940 -0.4826 9.0916

You might want to rotate the plot again to get it into the right orientation, as in your sketch.

Additional Info: polyfit() instead of nlinfit

Since one can compute this flow profile analytically, one knows in advance that is is a parabola. You can also use polyfit to fit a parabola.

par_poly_fit = polyfit(r, XMean, 2) % // it yields the values: par_poly_fit = -0.0023 -0.0023 0.1934

Plotting that paraobla gives a line pretty much identical to the line, which we got with the optimizer, but it is just more stable since it does not depend on an initial value.

 plot(r_fit, polyval(par_poly_fit, r_fit),'g--'

Multi-dispatch is the ability to choose which version of a function to call based on the runtime type of the arguments passed to the function call.

Here's an example that won't work right in C++ (untested):

class A { }; class B : public A { }; class C : public A { } class Foo { virtual void MyFn(A* arg1, A* arg2) { printf("A,A\n"); } virtual void MyFn(B* arg1, B* arg2) { printf("B,B\n"); } virtual void MyFn(C* arg1, B* arg2) { printf("C,B\n"); } virtual void MyFn(B* arg1, C* arg2) { printf("B,C\n"); } virtual void MyFn(C* arg1, C* arg2) { printf("C,C\n"); } }; void CallMyFn(A* arg1, A* arg2) { // ideally, with multi-dispatch, at this point the correct MyFn() // would be called, based on the RUNTIME type of arg1 and arg2 pFoo->MyFn(arg1, arg2); } ... A* arg1 = new B(); A* arg2 = new C(); // Using multi-dispatch this would print "B,C"... but because C++ only // uses single-dispatch it will print out "A,A" CallMyFn(arg1, arg2);

7592747 0 how to remove namespace and retain only some of the elements from the original XML document using XSL?

Below is my XML. I wanted to parse this using XSL. What I want to achieve is to remove the namespace (xmlns) then just retain some of the elements and their attributes. I found a way to remove the namespace but when I put it together with the code to retain some of the elements, it doesn't work. I already tried the identity but still didn't work.

I hope someone out there could share something. Thank you very much in advance.

XML Input:

Just write your code to play Audio by using AudioURL

I Like to know if u have any clarification in this regard.

Actually I did that in visual studio and it worked well in preview (display the current date by default for the parameter and allow people to select other date) .

But for some reason, the subscription setting still asked me for the parameter value (as in the early post "Report Parameter Values").

From what I learned from the forums(https://www.millennium.berkeley.edu/pipermail/tinyos-help/2007-July/026348.html) TOSSIM always sends at 0dbm and doesn't give dynamic change in the signal strength. Remember simulators have the limitations and Tossim assumes everything runs smoothly. But if you are interested in estimating quality you should consider some other parameter such as gain which can be programmed using the TOSSIM.

All you have to do is correct your signatures like so:

const T& operator [](char* b) const; T& operator [](char* b);

I've removed the const qualifier from the second operator.

if I use AssArray["llama"]=T, how am I supposed to get the value of T into the operator overloading-function?

You don't. You just return a reference to where the new value should be stored, and the compiler will take care of the rest. If "llama" does not exist in the array, you need to create an entry for it, and return a reference to that entry.

Math expressions can be very complex, I presume you are referring to arithmetic instead. The normal form (I hope my wording is appropriate) is 'sum of monomials'.

Anyway, it's not an easy task to solve generally, and there is an ambiguity in your request: 2 expressions can be syntactically different (i.e. their syntax tree differ) but still have the same value. Obviously this is due to operations that leave unchanged the value, like adding/subtracting 0.

From your description, I presume that you are interested in 'evaluated' identity. Then you could normalize both expressions, before comparing for equality.

To evaluate syntactical identity, I would remove all parenthesis, 'distributing' factors over addends. The expression become a list of multiplicative terms. Essentially, we get a list of list, that can be sorted without changing the 'value'.

After the expression has been flattened, all multiplicative constants must be accumulated.

a simplified example:

a+(b+c)*5 will be [[1,a],[b,5],[c,5]] while a+5*(c+b) will be [[1,a],[5,c],[5,b]]

edit after some improvement, here is a very essential normalization procedure:

:- [library(apply)]. arith_equivalence(E1, E2) :- normalize(E1, N), normalize(E2, N). normalize(E, N) :- distribute(E, D), sortex(D, N). distribute(A, [[1, A]]) :- atom(A). distribute(N, [[1, N]]) :- number(N). distribute(X * Y, L) :- distribute(X, Xn), distribute(Y, Yn), % distribute over factors findall(Mono, (member(Xm, Xn), member(Ym, Yn), append(Xm, Ym, Mono)), L). distribute(X + Y, L) :- distribute(X, Xn), distribute(Y, Yn), append(Xn, Yn, L). sortex(L, R) :- maplist(msort, L, T), maplist(accum, T, A), sumeqfac(A, Z), exclude(zero, Z, S), msort(S, R). accum(T2, [Total|Symbols]) :- include(number, T2, Numbers), foldl(mul, Numbers, 1, Total), exclude(number, T2, Symbols). sumeqfac([[N|F]|Fs], S) :- select([M|F], Fs, Rs), X is N+M, !, sumeqfac([[X|F]|Rs], S). sumeqfac([F|Fs], [F|Rs]) :- sumeqfac(Fs, Rs). sumeqfac([], []). zero([0|_]). mul(X, Y, Z) :- Z is X * Y.

Some test:

?- arith_equivalence(a+(b+c), (a+c)+b). true . ?- arith_equivalence(a+b*c+0*77, c*b+a*1). true . ?- arith_equivalence(a+a+a, a*3). true .

I've used some SWI-Prolog builtin, like include/3, exclude/3, foldl/5, and msort/2 to avoid losing duplicates.

These are basic list manipulation builtins, easily implemented if your system doesn't have them.

edit

foldl/4 as defined in SWI-Prolog apply.pl:

:- meta_predicate foldl(3, +, +, -). foldl(Goal, List, V0, V) :- foldl_(List, Goal, V0, V). foldl_([], _, V, V). foldl_([H|T], Goal, V0, V) :- call(Goal, H, V0, V1), foldl_(T, Goal, V1, V).

handling division

Division introduces some complexity, but this should be expected. After all, it introduces a full class of numbers: rationals.

Here are the modified predicates, but I think that the code will need much more debug. So I allegate also the 'unit test' of what this micro rewrite system can solve. Also note that I didn't introduce the negation by myself. I hope you can work out any required modification.

NSURLConnection is great for getting a file from the web... It doesn't "wait" per se but its delegate callbacks:

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data - (void)connectionDidFinishLoading:(NSURLConnection *)connection

...allow you to be notified when data has been received and when the data has been completely downloaded. This way you can have the App show (if you like) a UIProgressBar as the data comes in and then handle the file as you please when it is completely received.

24579128 0 R slow assignment in setRefClass

Perhaps this question should be in some programming forum, but I thought I would ask it in the statistics community. The following code illustrates the problem when performing global assignment in R's setRefClass:

class <- setRefClass("class", fields = list( params = "numeric" ), methods = list( initialize = function() { params <<- 5 }, do.stuff = function() { for (i in 1:1e5) params <<- 2 } )) # FAST: params <- 5 time <- Sys.time(); for (i in 1:1e5) params <- 2; time <- Sys.time() - time print(time) # SLOW: newclass <- class$new() time <- Sys.time(); newclass$do.stuff(); time <- Sys.time() - time print(time)

And pqR shows a slight improvement in runtime, but nothing drastic.

I would like to know why this is happening... in my mind, assigning a variable should be fast. Maybe this has something to do with locating an object "slot" (variable location), similar to S3/S4 classes. I bet I can only observe such behavior with R, and not C++.

would prevent that, except if the user of the code used const_cast to remove the const.

If this is only a timeout error, try putting set_time_limit(xx); on top of your code. With xx corresponding to the time to wait in seconds.

Putting 0 means no time limit, but it may be endless if your script enters an infinite loop, of if it is waiting a feedback from your encoding command that never arrives...

<div id="slidingDiv<?=$row["id"] ?>" class="toggleDiv row-fluid single-project"> <div class="span6"> <img src="adm/images/<?=$row["image"] ?>" alt="project <?=$row["id"] ?>" /> </div> <div class="span6"> <div class="project-description"> <div class="project-title clearfix"> <h3><?=$row["name"] ?></h3> <span class="show_hide close"> <i class="icon-cancel"></i> </span> </div> <div class="project-info"> <?php $check = $row["name"]; $query2 = mysqli_query($dblogin, "SELECT * FROM devices RIGHT JOIN repair ON devices.name = repair.modelid WHERE repair.modelid=$check"); while($row = mysqli_fetch_assoc($query2)) { ?> <div> <span><?=$row["price"] ?> ,-</span><?=$row["name"] ?> </div> <?php } ?> <div> <span>Client</span>Some Client Name </div> <div> <span>Date</span>July 2013 </div> <div> <span>Skills</span>HTML5, CSS3, JavaScript </div> <div> <span>Link</span>http://examplecomp.com </div> </div> <p>Believe in yourself!

EDIT

SELECT * FROM devices RIGHT JOIN repair ON devices.name = repair.modelid WHERE repair.modelid LIKE '%iPhone 6%' LIMIT 0 , 30

Gives this result

38486591 0 SharePoint 2013 get Group Owner Login Name and set Group Owner via JavaScript

I'm try to first find out an owner of a Group in SharePoint 2013, and then I would like to try and set the owner of a Group using JavaScript, I am will to try either JSOM, or REST API. (if I understand how that, JSOM vs. REST works)

I have tried with JSOM:

function getGroupOwner (desiredGroupName) { var clientContext = new SP.ClientContext.get_current(); var web = clientContext.get_web(); var groups = web.get_groups(); var group = groups.getByName(desiredGroupName); var groupOwner = group.get_owner(); clientContext.load(web); clientContext.executeQueryAsync( function() { console.log('Success'); var ownerLoginName = groupOwner.get_loginName(); console.log('ownerLoginName: ' + ownerLoginName); }, function (sender, args) { console.log('Error: ' + args.get_message()); } }

I at least get a "Success", but it then gives me an error of:

The property or field 'LoginName' has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.

Once I solve this, I was going to move onto the set_owner() function.

Any advice on this would be appreciated.

First of all, if I understood you, for what you want you are going to need jQuery, why? Because javascript doesn't know what CSS properties are affecting to an specific element.

Second, the way you are using CSS is not the correct one, you are mixing desing and functionality and for the easiest task like this one you will encounter problems like this one. CSS is not intended to show or hide menus even if you can, CSS is to style things even dinamically but when the user interaction gets involved you are screwed. So be careful :P

In jQuery should be something like this:

$(document).ready(function() { $('ul').on('click', 'li a', function() { $(this.parentElement.parentElement).hide(); }); });

Just add below code in your edit-text

android:hint="Your Text"; // XML

or even you can set it run time by using following code

EditText text = new (EditText) findviewbyid (R.id.text1); text1.setHint("Enter your message here");

There are 3 types of javascript popups:

Alert - it has only "yes" button
Confirmation - it has "yes" as well as "no" buttons
Prompt - it has input area to write something and "yes" and "no" buttons

You need to make sure which type of popup is shown and act accordingly.

18886672 0 How do I match the root of a content URI in Android 4.3?

I'd like to return some results when someone hits the root of my ContentProvider, which has worked fine up until now. As of Android 4.3, however, I cannot match the root! Here's everything I've tried, and nothing will work. This returns -1 under 4.3, but not under earlier versions.

How do I match that URI?

private int testMatch(){ UriMatcher mUriMatcher = new UriMatcher(0); mUriMatcher.addURI("com.someone.app.provider.thingy", "/#", 0); mUriMatcher.addURI("com.someone.app.provider.thingy", "/", 1); mUriMatcher.addURI("com.someone.app.provider.thingy", "", 2); mUriMatcher.addURI("com.someone.app.provider.thingy", "/*", 3); mUriMatcher.addURI("com.someone.app.provider.thingy", "#", 4); mUriMatcher.addURI("com.someone.app.provider.thingy", "*", 5); mUriMatcher.addURI("com.someone.app.provider", "thingy", 6); Uri uri=Uri.parse("content://com.someone.app.provider.thingy"); return mUriMatcher.match(uri); }

Excuse any novice jibberish I may use to explain my conundrum but hopefully someone here will be able to look past that and provide me with an answer to get me unstuck.

SESSIONS

For each session in the Sessions table that has an appID of 1, I want to get the users name from the Users table. The Sessions userID column is linked with the Users tables id column.

So my desired result would be:

A validation is a check that the value entered is legitimate for the context of its field (from technical perspective), for example: is 5 as a numeric value acceptable for Age(v.s. -5)?, while -5 is acceptable as Temperature for example.

The business rule is more of a business perspective. It is a check that the values (that passed the validation) are acceptable by the policies and procedures of the business. E.g. the person who is allowed to register has to be a resident, and 18 years old or more..etc. The business rule might check one (or more) field(s) value(s), and might consult data stored in a database and/or do some calculation(s) to ensure that the value(s) pass the business rules.

So, for the example posted above by hanna, the value 15 should pass the field validation (as it is a valid value for Age), but it will not pass the business rule check that the married person's age must be >15.

There are a set of several templates that control the checkout page. They can be found in the WooCommerce plugin folder in templates/checkout.

You can put a woocommerce/templates/checkout folder inside your theme's folder and copy the templates you want to alter into it. Those will override the normal templates without altering the plugin itself. That way your changes won't get overwritten when WooCommerce is updated.

The parser will see this as either nesting of documents or improper placement of the XML declaration, both of which will cause an error.

Should I even be using ImageView? I've seen some answers suggesting that a WebView is a better starting point.

This is the way I solved it in the end. I simply wrapped the image filename in some HTML and gave it to a webview.

This gave me the following specific benefits:-

The detailed user behaviour (eg. zoom rate, pinch sensitivity, availability of an on screen control) were consistent with the browser, and so familiar to the user's muscle memory
I don't need to depend on any third party code
Since it's core Android, it's probably better tested against edge cases (eg. one library I considered didn't support landscape)
I don't need to worry about out of memory situations with Bitmap processing
In the future, I might want to provide "web page" as one of the items in my ViewPager anyway, so one stone, two birds.

Here is the code I ended up with.

File imgFile = new File(FILESDIR,FILENAME); if(imgFile.exists()){ WebView wv = (WebView) rootView.findViewById(R.id.imageView1); wv.getSettings().setBuiltInZoomControls(true); wv.getSettings().setDisplayZoomControls(true); String html = ("<html><img src='"+imgFile.getName()+"'></html>" ); wv.loadDataWithBaseURL("file://"+imgFile.getAbsolutePath(), html, "text/html", "utf-8", ""); }

The first seed node is special, as documented in the Cluster documentation: http://doc.akka.io/docs/akka/snapshot/java/cluster-usage.html

It must be the same 1st configured node on all nodes, in order for all of them to be really sure that they join the same cluster.

Quote:

The seed nodes can be started in any order and it is not necessary to have all seed nodes running, but the node configured as the first element in the seed-nodes configuration list must be started when initially starting a cluster, otherwise the other seed-nodes will not become initialized and no other node can join the cluster. The reason for the special first seed node is to avoid forming separated islands when starting from an empty cluster. It is quickest to start all configured seed nodes at the same time (order doesn't matter), otherwise it can take up to the configured seed-node-timeout until the nodes can join.

Once more than two seed nodes have been started it is no problem to shut down the first seed node. If the first seed node is restarted, it will first try to join the other seed nodes in the existing cluster.

The Array.Clear method will let you clear (set to default value) all elements in a multi-dimensional array (i.e., int[,]). So if you just want to clear the array, you can write Array.Clear(myArray, 0, myArray.Length);

There doesn't appear to be any method that will set all of the elements of an array to an arbitrary value.

Note that if you used that for a jagged array (i.e. int[][]), you'd end up with an array of null references to arrays. That is, if you wrote:

int[][] myArray; // do some stuff to initialize the array // now clear the array Array.Clear(myArray, 0, myArray.Length);

Then myArray[0] would be null.

As said, you're asking about regular expressions commonly called a "regex". Take a look at Regular-Expressions.info for tons of good information. The page you're probably most interested in is the Literal Characters and Special Characters, which largely answers your OP. A great site to test your regex is Rubular.com. It's designed for Ruby, but works great for nearly anything I've thrown at it (sed expressions, C# replace, JS replace, etc.).

The __-prefix is a convention surrounded by built-in magic: http://www.php.net/manual/en/userlandnaming.rules.php, never start a function or variable with this if you can avoid it.

The first is a token, the second a convention.

While there is a file system provider s3fs build on fuse. Is not always a good idea to try to mount it to the file system. Instead you should either use command line tools s3cmd or build in access to s3 into your filesystem.

The reason why I would recommend against it is that s3 is not a block device while the rest of your file system is. Everything on s3 is treated as a complete object. You can't read or write to a block of the object.

If all your are doing with the mount is copying files in its entirety to and from s3, a file system mount may work reasonably well. But you can't run anything that would expect block level acccess to files on that mount.

The problem is not that the class is a partial class. The problem is that you try to derive a static class from another one. There is no point in deriving a static class because you could not make use Polymorphism and other reasons for inheritance.

If you want to define a partial class, create the class with the same name and access modifier.

You can set a background-color on the :before element instead of a border-top to make it work. The pseudo-element can have a height of just 1px and a width: 100px;.

 p { position: relative; margin: 50px auto; font-size: 1.5em; } p:before { content: ""; position: absolute; top: 50px; width: 100px; margin: 0 auto; height: 1px; background-color: black; /*Removed border, added background-color */ }

31937093 0 Table Is Not Deleted

i am trying to delete a table, and i followed this link http://www.techonthenet.com/sqlite/truncate.php as a tutorial. but when i execute the below code, for the first run, i expected the sqliteFactory.getRowCount() method will return 0 rows as the method sqliteFactory.deleteTable(SysConsts.SQLITE_DATABASE_TABLE_NAME); was just called before it, but what i received is a rowCount which is not zero.

in the second run of the same code, i expected the sqliteFactory.CreateTable(SysConsts.SQLITE_DATABASE_TABLE_NAME); to display Log.i(TAG, "CreateTable", "table: ["+tableName+"] does not exist, will be created"); as the table should have been deleted, but i received Log.i(TAG, "CreateTable", "table: ["+tableName+"] already exists.");

kindly please let me know how why the table is not deleted? and should i do commit after deletion?

main code:

public static void main(String[] args) throws SQLException, ClassNotFoundException { SQLiteFactory sqliteFactory = new SQLiteFactory(); sqliteFactory.newSQLiteConn(SysConsts.SQLITE_DATABASE_NAME); sqliteFactory.CreateTable(SysConsts.SQLITE_DATABASE_TABLE_NAME); sqliteFactory.insertRecord(new Record("001", "55.07435", "8.79047", "c:\\bremen_0.xml")); Log.d(TAG, "main", "rowCount: "+sqliteFactory.getRowCount()); //sqliteFactory.selectAll(); //sqliteFactory.getNodeID("53.074415", "8.788047"); sqliteFactory.selectXMLPathFor("53.074415", "8.788047"); Log.d(TAG, "", ""+sqliteFactory.getRowCountLatLngFor("53.074415", "8.788047")); Log.d(TAG, "", ""+sqliteFactory.getRowCountNodeIDFor("001")); Log.d(TAG, "", ""+sqliteFactory.getRowCountXMLPathFor("c:\\brem_0.xml")); sqliteFactory.deleteTable(SysConsts.SQLITE_DATABASE_TABLE_NAME); Log.d(TAG, "main", "rowCount: "+sqliteFactory.getRowCount()); }

isTableExists:

private boolean isTableExists(String tableName) throws ClassNotFoundException, SQLException { Connection conn = this.getConnection(); DatabaseMetaData dbMeta = conn.getMetaData(); ResultSet resSet = dbMeta.getTables(null, null, tableName, null); boolean exists = false; if (resSet.next()) { exists = true; } else { exists = false; } resSet.close(); conn.close(); return exists; }

deleteTable:

public void deleteTable(String tableName) throws ClassNotFoundException, SQLException { if (this.isTableExists(tableName)) { Log.i(TAG, "deleteTable", "table: ["+tableName+"] already exists, and will be deleted."); Connection conn = this.getConnection(); PreparedStatement ps = conn.prepareStatement("delete from "+this.TABLE_NAME); ps.close(); conn.close(); } else { Log.i(TAG, "deleteTable", "table: ["+tableName+"] does not exist, can't be deleted."); return; } }

getRowCount:

public int getRowCount() throws SQLException, ClassNotFoundException { Connection conn = this.getConnection(); Statement stmt= conn.createStatement(); ResultSet resSet = stmt.executeQuery("SELECT COUNT(*) AS rowCount FROM "+TABLE_NAME+";"); int cnt = resSet.getInt("rowCount"); resSet.close(); stmt.close(); conn.close(); return cnt; }

This usually means you are blocking the UI thread (e.g. running a long operation inside a button click handler). Instead of using the UI thread, you will generally need to offload long I/O operations to the ThreadPool or your own worker threads. This is not always easy to do and requires careful design and a good understanding of concurrency, etc.

void expect(String xpath, Matcher matcher) { String actual = fromXpath(xpath); // convert actual into correct type for matcher assertThat(actual, matcher); }

I want method like Matcher.getType. So I could do something like

if (matcher.getType().equals(Long.class)) { long actual = Long.parseString(fromXpath(xpath)); }

But I cannot see for the life of me how I get the of the matcher.

You need to send the data out from the server code:

app.get('/content.json',function(req, res) { request("http://www.google.com", function(error, response, body) { res.send(body); }); });

Edit: As the JS client is expecting appication/json, you should set the response header sent from server as well:

res .header('Content-Type', 'application/json') .send(body);

When a server listens on a computer, it specifies a port it wants it's connections coming in from , so ports are important for setting up servers. This is useful as you can have multiple applications listening on different ports without the different applications accidentally talking to eachother. So you should decide on a port that isn't a standard( 80 is for HTTP for example) to exclusively use for you gameserver so the client knows which port to send the requests to.

If you want to handle multiple connections at once the best thing to do is threading.

A simple way of generating a printable report from a Datagridview is to place the datagridview on a Panel object. It is possible to draw a bitmap of the panel.

Here's how I do it.

'create the bitmap with the dimentions of the Panel Dim bmp As New Bitmap(Panel1.Width, Panel1.Height)

'draw the Panel to the bitmap "bmp" Panel1.DrawToBitmap(bmp, Panel1.ClientRectangle)

I create a multi page tiff by "breaking my datagridview items into pages. this is how i detect the start of a new page:

'i add the rows to my datagrid one at a time and then check if the scrollbar is active. 'if the scrollbar is active i save the row to a variable and then i remove it from the 'datagridview and roll back my counter integer by one(thus the next run will include this 'row.

Private Function VScrollBarVisible() As Boolean Dim ctrl As New Control For Each ctrl In DataGridView_Results.Controls If ctrl.GetType() Is GetType(VScrollBar) Then If ctrl.Visible = True Then Return True Else Return False End If End If Next Return Nothing End Function

I haven't found a way to do this that isn't a hack, but here's the simplest hack I could think of:

<script type="text/javascript"> function tweakWidthForScrollbar() { var db = document.body; var scrollBarWidth = db.scrollHeight > db.clientHeight ? db.clientWidth - db.offsetWidth : 0; db.style.paddingRight = scrollBarWidth + "px"; } </script> ... <body onresize="tweakWidthForScrollbar()">

The idea is to detect whether the vertical scrollbar is in use, and if it is, calculate its width and allocate just enough extra padding for it.

You want to be using the right shift operators (there are two) and shift thevalue right:

if ((input >>> 24) == 0) { // high-order 40 bits are all 0. }

Alternatively, you can simply bit-mask with:

if ((input & 0xFFFFFFFFFF000000L) == 0) { // high-order 40 bits are all 0. }

Note that >>> will put 0 in the high-order bits, and >> will put 0 for positive numbers, and 1 for negative.

you don't need to create a thread just to start timer in it. You can just start timer in your main thread. Its function will run on a thread from threadpool.
I don't see why you need to create a thread for start() function. It needs to be run at least partially before your timer first work. So, you may execute RegKeys = load.read(RegKeys); (and probably other code from start) in main thread. if you insist on running it in separate thread, ensure that RegKeys is initialized. It can be done by, e.g. setting ManualResetEvent after initializing RegKeys and waiting for this ManualResetEvent in timer callback.
You should stop timer on process exit.
you need to wait for started thread's stopping using Thread.Join method or by waiting on some WaitHandle (ManualResetEvent e.g.) being set in thread on finish.

It's depend on what you exactly mean under "deleting of all rows". The method GridUnload could be very helpful in many cases, but it delete more as only grid contain.

Another method used intern in jqGrid is:

var trf = $("#list tbody:first tr:first")[0]; $("#list tbody:first").empty().append(trf);

Probably it is what you need. It delete all grid rows excepting of the first one. You can overwrite the code also as the following

var myGrid = $("#list"); // the variable you probably have already somewhere var gridBody = myGrid.children("tbody"); var firstRow = gridBody.children("tr.jqgfirstrow"); gridBody.empty().append(firstRow);

Length is taken into account, but not in the way you expect. In string comparison, the first characters of each string are compared to each other first. If they are equal, then the second characters are compared and so on. So in your example, the first characters to be compared are '1' and '8'. '8' is larger.

If you had compared "10.72" against "1.87", the first characters would be equal, so the next thing would be to compare "0" against ".".

If you want to compare numeric values, you have to convert the strings to their numeric representation, or else you would have to write your own comparator that would treat strings as numerics. I hope that sheds some light on it.

I had the same issue. And so starts a search of SO. So the above helped me out, but the whole, "if iOS9 thing" might be best framed like this:

if ([self respondsToSelector:@selector(inputAssistantItem)]) { // iOS9. UITextInputAssistantItem* item = [self inputAssistantItem]; item.leadingBarButtonGroups = @[]; item.trailingBarButtonGroups = @[]; }

Happily, I'd created a sub-class of a UITextField, (CHTextField) and was in use everywhere. So it was a very easy fix to whack this in the over-ridden "init" method.

Hope it helps.

You can use events to update the Combobox SourceItems on a parent page that displays

ie in your custom control or form that handles creating the new item

 public static readonly RoutedEvent NewItemAddedEvent = EventManager.RegisterRoutedEvent("NewItemAdded", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(CloseableTabItem)); public event RoutedEventHandler NewItemAdded { add { AddHandler(NewItemAddedEvent, value); } remove { RemoveHandler(NewItemAddedEvent, value); } }

private void SaveButton_Click(object sender, RoutedEventArgs e) { ProActive.Contact currentContact = (ProActive.Contact)ItemsListBox.Items.CurrentItem;

 switch (MessageBox.Show("Are you sure?", "Save Changes", MessageBoxButton.YesNoCancel)) { case MessageBoxResult.Yes: if (currentContact.EntityState == System.Data.EntityState.Detached) ProActive.App.ProActiveDatabaseEntities.Contacts.AddObject(currentContact); ProActive.App.ProActiveDatabaseEntities.SaveChanges(); this.RaiseEvent(new RoutedEventArgs(NewItemAddedEvent, this)); break; }

then in the master page that displays the combo box, attach the event that fired after you 'save' the new item

ProActive.TabPagesControls.AllContactsDetailsControl cdc = new AllContactsDetailsControl(); cdc.NewItemAdded += AllContactsDetailsNewItemAdded;

then handle the event on the parent page after it gets fired to re-load the itemssource

 private void AllContactsDetailsNewItemAdded(object sender, RoutedEventArgs e) { // New item added so refresh the items listbox AllContactListItemsListBox.ItemsSource = from c in ProoActive.App.ProActiveDatabaseEntities.Contacts select c; }

I know these kind of insertions (and their differences):
Map[key] = value; 

Map[key] is not strictly for insertions. You can assign to that value as well. The postincr/postdecr operators do modify those values, as a side effect.

So Map[key]++ is legal, and does what you might expect -- increments the value stored at Map[key]. Equivalent to:

Map[key] = Map[key] + 1

I think the main confusion here is the notion that that main is the first and last thing that happens in C++ program. Whilst it is [1] the first part of YOUR program, there is usually some code in the application that sets up a few things, parses command line arguments, opening/initialization of standard I/O (cin, cout, etc) and other such things, which happen BEFORE main is called. And main is essentially just another function, called by the C++ runtime functionality that does that "fix things up before main".

So, when main returns, it goes back to the code that called it, which then cleans up the things that need cleaning up (closing standard I/O channels, and many other such things), before actually finishing up by calling some OS function to "terminate this process". As part of this "terminate this process" functionality is (in most OS's) a way to signal "success or failure" to the OS, so that some other process monitoring the application can determine "if all is well or not". This is where, eventually, the 0 (or 1 if you use return 1; in main) ends up.

[1] If there are static objects with constructors that are part of the user's code, then these will be performed before any code in main [or at least, before any code in main that belongs to the user's application] is executed.

You don't say precisely what you're trying to do, but I can say with a great deal of confidence you are doing it wrong. From your code, I'll guess that emailTranscript.txt contains a form letter and nameAddresses.csv contains the data to be substituted in.

The biggest error, and the one I suspect is your problem, is that -F specifies the field separator. You want -v, to set a variable.

The standard way to send navigation parameters between pages in WP8 is to use

NavigationService.Navigate(new Uri("/MainPage.xaml?text=" + textBox1.Text, UriKind.Relative));

Then check for the parameter on the OnNavigatedTo() Method on the page you have navigated to.

protected override void OnNavigatedTo(NavigationEventArgs e) { string settingsText = NavigationContext.QueryString["text"]; }

For Windows Phone 8.1 you no longer navigate using a URI. The approach is to use:

this.Frame.Navigate(typeof(MainPage), textBox1.Text);

Then on the loadstate for the page you are navigating to you can get the data by using:

private async void navigationHelper_LoadState(object sender, LoadStateEventArgs e) { string text = e.NavigationParameter as string; }

Hope this helps.

the issue is with the z-index of the div containing the image and the div containing the footer.

the easiest solution is to put the footer after the div with your content. The only time z-index should come into play is if you are trying to put items on top of the image for effect.

<div id="content-wrapper"> <div id="nav"> <span>NAV</span> </div> </div> <div id="footer"> <span>FOOTER</span> </div>

you can easily add the footer in the container, attach at the bottom as well. see if this example helps: https://plnkr.co/edit/GDfzul2qKApw6JGhQSbb?p=preview

It means if you try to serialize/deserialize more than 20 different types you will require a paid license. See the test in the source code here. In this case 20 different types are trying to be deserialized, causing a License Exception.

From you description, you should be well within the limit of the free license and not have to worry about hitting any limitations.

It is possible to build a version of subversion that doesn't have this problem. It seems that the problem is the apr and apr-util libraries (see Subversion, Mac OS X, and SMB).

The work around I used is to compile subversion using OS X's versions apr, apr-util & apxs libraries.

Here is how to do it:

Get the a svn tarball, and un-tar it somewhere suitable
./configure --prefix=/opt/subversion/ --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr --without-berkeley-db --with-apxs=/usr/sbin/apxs
- --prefix=/opt/subversion/: put subversion in /opt/subversion, which is handy if you use svnX.
- --with-apr=/usr/local/apr: use OS X's apr library.
- --with-apr-util=/usr/local/apr: use OS X's apr-util library.
- --with-apxs=/usr/sbin/apxs: use OS X's apxs library.
- --without-berkeley-db: This isn't strictly part of the fix, but I've never used anything other than subversion FSFS, so I don't build with berkeley-db.
sudo make install

I have successfully done this on OS X 10.5, with subversion 1.6.13.

svnX is happy with this too.

25845536 0 Trait to check if some specialization of template class is base class of specific class

There is std::is_base_of in modern STL. It allow us to determine whether the second parameter is derived from first parameter or if they are the same classes both or, otherwise, to determine is there no such relation between them.

Is it possible to determine whether the one class is derived from some concrete template class without distinction of which concrete actual parameters involved to its specialization?

Say, we have;

template< typename ...types > struct B {};

And

template< typename ...types > struct D : B< types... > {};

Is it possible to define a type trait:

template< typename T > is_derived_from_B;

Such that it is derived from std::true_type when T is any specialization of D and derived from std::false_type if T is not derived from any specialization of B?

You already got it, you just needed to create the container for the output (the numnights element).

Anyway the code is a little bit cleaner in this way:

$(document).ready(function(){ $(".daypicker").on('change', function(){calculateNights();}); }); function calculateNights() { var arrivalday = $("#arrivalday").val(); var departureday = $('#departureday').val(); var numberNights = departureday - arrivalday; numberNights = (numberNights < 1) ? numberNights + 7 : numberNights; $("#numNights").html(numberNights); }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select required="required" class="daypicker" id="arrivalday" name="arrivalday"> <option></option> <option value="1">Monday</option> <option value="2">Tuesday</option> <option value="3">Wednesday</option> <option value="4">Thursday</option> <option value="5">Friday</option> <option value="6">Saturday</option> <option value="7">Sunday</option> </select> <select required="required" class="daypicker" id="departureday" name="departureday"> <option></option> <option value="1">Monday</option> <option value="2">Tuesday</option> <option value="3">Wednesday</option> <option value="4">Thursday</option> <option value="5">Friday</option> <option value="6">Saturday</option> <option value="7">Sunday</option> </select> <hr> <div id="numNights"></div>

12114425 0 SQL - use variable as column in SELECT statement and WHERE clause

I'm trying to pull the students that are tardy for the previous period from our attendance database (SQL Server 2008). The period attendance is stored in ATT.A1, ATT.A2 ... ATT.A7. I want to schedule a job to run each hour, starting at 9am, and pull the tardy students, but I can't figure out the code.

Here's my code (pseudo-code):

Declare @Period varchar(6) Set @Period = 'att.a' + Cast((DATENAME(hour, GETDATE()) - 8) as varchar(1)) Select SC, SN, DT, @Period as Period, ATT.A1 From ATT Where SC = '9' and @Period = 'T' and DT = DATEADD(day, DATEDIFF(day, 0, GETDATE()), 0)

When I use this, I get no results. If I remove @Period = 'T' from the Where clause, I get the following:

9 5177 2012-08-24 00:00:00.000 att.a1 T 9 5211 2012-08-24 00:00:00.000 att.a1 9 5225 2012-08-24 00:00:00.000 att.a1 T 9 5229 2012-08-24 00:00:00.000 att.a1 T 9 5235 2012-08-24 00:00:00.000 att.a1 V 9 5242 2012-08-24 00:00:00.000 att.a1 T 9 5268 2012-08-24 00:00:00.000 att.a1

I know that when I use @Period in the SELECT statement and WHERE clause it's using the literal string value of @Period, but I need it to use the value of @Period as Table.Column.

So, at 9:00 it will select from ATT.A1, 10:00 from ATT.A2 ... 15:00 from ATT.A7 and each time compare whether ATT.A# = 'T'

I hope that's clear.

Thanks, Anthony

35184881 0 Default landing page for an area independent of a default controller?

I have an MVC5 website with a few areas in it. Each area has its own set of controllers and obviously every controller has a default Index.cshtml as landing page. So far so good.

But how do I go about implementing a landing page for an Area? I don't think there can be a landing page for an area independent of the controllers, so perhaps I would need to use sort of an area Home controller that would volunteer a landing page.

The thing is that I want an URL like this to work:

http://www.domain.exe/AreaN/

currently that does not work unless I make it like this:

http//www.domain.exe/AreaN/Controller/

at this point my Area registration route looks like this

context.MapRoute( "AreaN_default", "AreaN/{controller}/{action}/{id}", new { action = "Index", id = UrlParameter.Optional }, new string[] { "Namespace" } );

35065421 0 Evaluate all formulas in a Workbook object

I want to evaluate all formulas in a Workbook object. I know there are XSSFFormulaEvaluator and HSSFFormulaEvaluator for evaluating formulas in XSSFWorkbook and HSSFWorkbook. But the workbook object I have belongs to Workbook class.

I can use something like this,

XSSFFormulaEvaluator.evaluateAllFormulaCells((XSSFWorkbook) workbook);

Is it ok to use this evaluator? Does it have any side effects to type-casting Workbook to XSSFWorkbook?

20021366 0 Regex - matching a multiline block by noting the absence of a string and then inserting it

What a mouthful of a subject.

So in essence I have a pattern I need to find in a file based on that pattern missing something.

For example what I HAVE is:

Huge amounts of preceding code... someHeader { someInfo = "blah blah blah"; } Huge amounts of ending code...

What I need to do is make it look like this:

someHeader { someDescription = "Excellent information found here!"; someInfo = "blah blah blah"; } Huge amounts of ending code...

The bottom line: I need to find all instances of the "someHeader" block that do not have a "someDescription" and insert it. "someInfo" will not always be there either so I really need to find every instance of "someheader\r\t\t{\r\t\t\t!someDescription" and replace it with "someheader\r\t\t{\r\t\t\tsomeDescription = "Excellent information found here!";\r"

I really am at a loss and have been banging on this for about a day. I have attempted sed, awk, perl and am dorking around with c# right now.

25935565 0 How do I change security for an existing named pipe?

I'm using Hyper V on Windows 8 and would like to be able to communicate with the virtual serial port through a named pipe. I give the pipe a name of choice and it works well communicating with the virtual os (XP, in my case) serial port, but only under the Admin user due to PipeSecurity settings.

Now I would like to be able to give full control for everyone on a named pipe created by Hyper-V. Programmatically or maybe with some Hyper V setting. I need to be able to communicate with the virtual os as a regular User.

I know how to set a certain security on a named pipe that I create myself using NamedPipeServerStream together with a PipeSecurity object. I'm mainly using C#, but I see that there are C++ API:s like SetSecurityInfo. But these requires a handle to the existing pipe.

In pseudo code I would like to do something like:

SetSecurityInfo("mypipe", new PipeAccessRule("Everyone", PipeAccessRights.FullControl, AccessControlType.Allow));

Anyone know how to do this? (C++ or preferrably C#)

Visual SourceSafe 2005 includes support for access over HTTP:

Remote Internet Access. This release of Visual SourceSafe introduces a new SourceSafe Internet plug-in for Visual Studio source control. The plug-in and its associated Web service enable remote Internet access to Visual SourceSafe databases over HTTP or HTTPS. The SourceSafe Internet plug-in supports the basic operations of database open, database add, check-in, checkout, and get, but does not provide rename, delete, get by time or by label, history, labeling, or share/branch functions. This plug-in is particularly helpful when you need to access your Visual SourceSafe databases when you are on the road.

Articles on setting it up seem to be scarce: Visual SourceSafe 2005 Internet Provider.

Also see:

But given that Visual SourceSafe 2005 will be retired from mainstream support on 12 April 2011 (with extended support ending on 12 April 2016), you might be better off going with Subversion (or similiar).

The element name is derived from the accessibility attribute of the underlying view. If an identifier attribute string is specified, that string is used as the name; otherwise, the label attribute string is used as the name. Contrast with the label method.

Don't use accessibility label to identify elements, use accessibility identifier.

In interface builder, the identifier can be set using runtime attributes:

open Identity Inspector - User Defined Runtime Attributes:

Key Path: accessibilityIdentifier Type: String Value: <your identifier>

I think what you're after is a scroll view with paging enabled to be the main view that contains subviews for each of your photos. With paging enabled (the default value for this boolean property is NO), the view will always "snap" to a multiple of its bounds, so the user is always either on one section of the scroll view or another (like in Photos, or on the Home screen).

You can set the pagingEnabled property of the UIScrollView to be true to gain this effect. You will then always have multiples of the bounds of the UIScrollView shown at a time (which you could fill with a view for a photo, such as a UIImageView).

Adding a space to the end of a string is as simple as just using +:

string = 'a' new_string = string + ' '

So you just need to iterate each item in your list and append the space:

for string in sliced: print string + ' '

So could just create a new list with a simple list comprehension

new_sliced = [slice + ' ' for slice in sliced]

Or alternatively, if you want to change the sliced list in place you could use the enumerate builtin to get the index of each element of your list

for i, slice in enumerate(sliced): sliced[i] = slice + ' '

20814433 0

strtr($str, ['<' => '', '.' => '']);

This will probably outperform anything else, because it doesn't require you to iterate over anything in PHP.

Resharper allows annotations to guide its magic. They are usually implemented by applying an attribute, though it uses external annotation files for BCL classes. You can use them in your own code. I think they are very underused.

There is an example of exactly your use case. Simply, apply [AspMvcAction] and [AspMvcController] to the appropriate parameters.

23252455 1 how to put data(id) in form (wtforms) and get it back on submit

I am new to wtforms, so I`ll really appreciate any help.

I need to display books names and near each put "Delete" button. I`ve read wtforms crash course but I have no idea how to solve my problem with it.

So I decided to do it other way - my best idea is to render to template a dict with id and name and on submit return id, but I still can`t do it. Code examples are below.

It`s view.py

@application.route('/delete', methods=['GET', 'POST']) def delete(): books_lib = mydatabase.get_all_books() form = DeleteForm(request.form) if request.method == 'POST': delete_id = form.id.data mydatabase.del_book(delete_id) return render_template('delete.html', form = form, books_lib = books_lib) return render_template('delete.html', form = form, books_lib = books_lib)

It`s template

<!DOCTYPE html> <html> <body> <h2>book to delete</h2> <form action="/delete" name="delete" method="POST"> {% if books_lib %} {% for id, book in books_lib.items() %} <p>{{book}}:<input type="submit" value="Delete" id="{{id}}"> {% endfor%} {% endif %} </form> </body> </html>

It`s form

class DeleteForm(Form): book = TextField("Book name", [validators.Length(min=2, max=25)]) id = HiddenField("id")

33554871 0 How to use/declare an unsigned Integer value in VHDL?

I'm trying to design a basic Vending machine on a Altera DE1-SoC Board. My question comes from trying to code the State Machine that will control the vending process. How do you track the $ value being added jumping between states? I think the code I'm trying to implement is written in a higher level language format and is not being able to be compiled in VHDL. Any ideas?

I already figured it out! Here's my solution:

Install Oracle XE in your PC this will give you the latest oci.dll (not php_oci8.dll)
Create a link between your user and the user you will need in connecting to your database.
Restart your PC then try running your code if it's not working copy the oci.dll of your Oracle XE (C:\Oracle\OUIHome\bin\oci.dll) then paste it in 9i replacing the old one (make sure to have a backup). then restart your PC.

Works fine on me. Thanks for those who help me in solving this one.

You can override -[NSView viewWillMoveToSuperview:] in a custom NSView subclass. This is simply a means for your class to be notified when its position in the view hierarchy is about to change. It doesn't have some deeper meaning other than what its name implies, but you can, of course, harness it to serve various purposes. It's not a method on a delegate or on the view controller, but you can implement such delegation yourself if you want.

Also, if your code is moving views around the view hierarchy, it can directly do whatever it wants immediately beforehand, which is also roughly when such a method would be called.

I did some poking around and it didn't seem like there was an easy way of doing this. I think to do it effectively you would probably need your own C functions which could provide a distance from one tsvector to another (then you could use KNN searches).

Either way there is not a very easy way to do this and it is likely a significant amount of work, but it seems like it should be a generally applicable problem so the general community might be interested in a solution.

Note this is not as trivial as it sounds. Suppose I write a book about Albert Lord's the Singer of Tales and his emphasis on poetic formulas. Suppose I call it "Albert Lord and the Ring of Words." This would create a tsvector of Albert:1 Lord:2 Ring:5 Words:7, The Lord of the Rings is Lord:2 Ring:5 which would create a very false sense of similarity. If you have any categorization involved, you would want to leverage that as well.

21338481 0 Count of numbers between A and B (inclusive) that have sum of digits equal to S

The problems is to find the count of numbers between A and B (inclusive) that have sum of digits equal to S.

Also print the smallest such number between A and B (inclusive).

Input:

Single line consisting of A,B,S.

Output:

Two lines.

In first line the number of integers between A and B having sum of digits equal to S.

In second line the smallest such number between A and B.

Constraints:

1 <= A <= B < 10^15

1 <= S <= 135

Source: Hacker Earth

My solution works for only 30 pc of their inputs. What could be the best possible solution to this?

The algorithm I am using now computes the sum of the smallest digit and then upon every change of the tens digit computes the sum again. Below is the solution in Python:

def sum(n): if (n<10):return n return n%10 + sum(n/10) stri = raw_input() min = 99999 stri = stri.split(" ") a= long (stri[0]) b= long (stri[1]) s= long (stri[2]) count= 0 su = sum(a) while a<=b : if (a % 10 == 0 ): su = sum(a) print a if ( s == su): count+=1 if (a<= min): min=a a+=1 su+=1 print count print min

Sorry I did not replay earlier. Quickly, I'll would like to present one way of catching this for your consideration. For simplicity, I'll just concentrate on caching your outputs using Output frontend.

In you application.ini you can setup your catching as follows:

resources.cachemanager.myviewcache.frontend.name = Output resources.cachemanager.myviewcache.frontend.customFrontendNaming = false resources.cachemanager.myviewcache.frontend.options.lifetime = 7200 resources.cachemanager.myviewcache.frontend.options.caching = true resources.cachemanager.myviewcache.frontend.options.automatic_serialization = true resources.cachemanager.myviewcache.backend.name = Apc

Note, that I use Apc as a backend. You may use file backend if you don't have or don't want Apc.

With this, I would cache your posts and comments separately. For example, in _posts.phtml you could do something similar to the following:

// first cache an output related to the body of your post with key being associated // with your post. if (!($this->viewCache()->start('post_' . (string) $this->object->post_id))) { echo $this->object->title; echo $this->object->text; } // now I cache an output of a comments associated with a give post if (!($this->viewCache()->start('post_comments_' . (string) $this->object->post_id))) { echo $this->partialLoop('_comments.phtml',$this->object->getComments()); }

In this example, viewCache() view helper is as follows:

class My_View_Helper_ViewCache extends Zend_View_Helper_Abstract { /** * * @return Zend_Cache_Frontend_Output */ public function viewCache() { return Zend_Registry::get('outputCache'); } }

Whereas I set outputCache into registry in the Bootstrap.php:

protected function _initPutChachesIntoRegistry() { $this->bootstrap('cachemanager'); $cacheManager = $this->getResource('cachemanager'); Zend_Registry::set('outputCache', $cacheManager->getCache('myviewcache')); }

Notice that caches are associated with keys which in turn relate to a given post and its comments. With this, when you get a new comment, you just reset a cache related to the given post. For example, in an action, you can remove comment cache for a post with $post_id=5 as follows:

$this->view->viewCache()->remove('post_comments_' . $post_id);

Hope that this will help you or at least give you some ideas how to make it.

Other than a very short list, you should not rely on everyone having the various font families on their computers.

Instead, try out Google WebFonts. In fact, use the search box on the left to find their Garamond equivalent. Works in all browsers (including older IE!) and looks great everywhere.

EDIT

Regarding your additional question, yes, the browser will look for the fonts in the order that you specify them, so putting "Garamond" before "EB Garamond" will show Garamond if available in the user's computer.

The mistake was not realising JavaScript's passing-by-reference when using objects such as Date objects.

In addition to Austin's answer, which did solve the problem by using d3 functionality, I investigated why my initial attempt by modifying the minDate and maxDate variables failed.

The problem is that when creating the variables

var minDate = dateDim.bottom(1)[0]["timestamp"]; var maxDate = dateDim.top(1)[0]["timestamp"];

I created pointers to the actual data instead of creating new objects with the same value as the minDate and maxDate objects. The line

minDate.setHours(minDate.getHours() - 1);

therefore then manipulated the actual underlying data within the date dimension dateDim, which then led to the peculiar behaviour.

The obvious solution would have been to create new Date() objects like this:

var minDate = new Date(dateDim.bottom(1)[0]["timestamp"]); var maxDate = new Date(dateDim.top(1)[0]["timestamp"]);

and then do the desired manipulations:

minDate.setHours(minDate.getHours() - 1); maxDate.setHours(maxDate.getHours() + 1);

If I understand correctly, you can hook into the Form Closing event.

So in your main form you can do something like:

Form2 form2 = new Form2(); form2.Show(); form2.FormClosing += new FormClosingEventHandler(form2_FormClosing); void form2_FormClosing(object sender, FormClosingEventArgs e) { this.Show(); }

Without having actually tested it, you should be able to copy the main django directory (/usr/lib/python2.6/site-packages/django for me) over into your project directory, and archive the whole thing. This will continue to keep everything importable (from django import ...), and make it so there's just one archive to extract.

Now, I wouldn't say this is a good way, but it's simple, and I think it'll work. I think.

Generally: yes, the bias weights should be updated and included in training just as any other weight in the NN (also in backpropagation).

In the example you've posted, the bias b1 is added to both neurons the hidden layer, and bias b2 to both neutrons in the output layer

Hidden layer: h1 = i1*w1 + i2*w2 + 1*b1 h2 = i1*w3 + i2*w4 + 1*b1 Output layer: o1 = h1*w5 + h2*w6 + 1*b2 o2 = i2*w7 + h2*w8 + 1*b2

With initial, and in this example, fixed, biases

b1 = 0.35 b2 = 0.60

This means that the biases for hidden neutrons is always exactly 0.35, and for output neutrons exactly 0.60. This, however, is not usual practice, as you want to train your NN to find "good" biases just as much you want it to train to find good weights.

Note also, in the comments of the link you provided, that another user has asked why biases are not changed, and the author has replied, quote:

"Hey, in the tutorials I went through they didn’t update the bias which is why I didn’t include it here."

This lack of a specific "why" possibly implies that the author of this example/tutorial is, however well-versed, no expert at the subject of NN, so you shouldn't out to much weight (no pun intended...) into the fast that the biases are not changed in this specific example.

If you really want to dig into a sound and thorough covering of NN in the context of back propagation, I would rather recommend you Michael Nielsen excellent book on NN and deep learning, specifically for this subject, Chapter 2. Note that the bias weights, here, are treated just as weights for neuron-neuron data transfer.

http://neuralnetworksanddeeplearning.com/chap2.html

Michael is a Google Researcher with numerous publicised articles in the subject of advanced NN and deep learning.

At the heart of backpropagation is an expression for the partial derivative ∂C/∂w of the cost function C with respect to any weight w (or bias b) in the network. The expression tells us how quickly the cost changes when we change the weights and biases.

The question is a little bit poor specified.

order the result in asc or desc depending upon a column value.

A column takes many values (as there are multiple rows).

Now, order by clause use an expression and order rows upon it. That expression should be morphotropic(;))

So, assuming stardard oracle's employee schema, managers are:

select * from emp e where exists (select emp_id from emp where e.id=emp.mgr_id)

An workaround query may be:

Select e.id, e.name, e.birth_date, case when (select count(*) from emp e where exists (select emp_id from emp where e.id=emp.mgr_id) ) --existence of manager > 0 then birth_date - to_date('1-Jan-1000','dd-mon-yyyy') else to_date('1-Jan-1000','dd-mon-yyyy') - birth_date end as tricky_expression from emp A order by 4;

That exexpresion is the case; Using a constant(subquery that decides there are managers) it changes values from positive to negative, that is, change the order direction.

UPDATE: with the details in the comments:

select id, name, birth_date emp_type from ( Select id, name, birth_date, emp_type, case when cnt_mgr > 0 then birth_date - to_date('1-Jan-1000','dd-mon-yyyy') else to_date('1-Jan-1000','dd-mon-yyyy') - birth_date end as tricky_expression from( Select e.id, e.name, e.birth_date, emp_type, count(case when emp_type='M' then 1 else 0 end) over() as mgr_count from emp A where your_conditions ) order by tricky_expression ) where rownum=1;

Your code isn't compilable. Here is the reasons:

The conditions must be placed into some method
The declaration of event handler must be moved out from the condition scope

Here is the workable code:

namespace WindowsFormsApplication1 { public partial class Form1 : Form { private int flag; FileSystemWatcher watcher = new FileSystemWatcher(); public Form1() { InitializeComponent(); watcher.Path = @"C:\"; watcher.Filter = "test.txt"; watcher.Changed += watcher_Changed; watcher.EnableRaisingEvents = true; } private void SetFlag() { FileInfo info = new FileInfo("c:\\test.txt"); if (info.Length > 0) flag= 1; } private void CheckFlag() { if(flag==1) { button1.PerformClick(); } } private void button1_Click(object sender, EventArgs e) { //Code for Redirection to New Form } void watcher_Changed(object sender, FileSystemEventArgs e) { SetFlag(); CheckFlag(); } } }

And now you can call method SetFlag() to set flag. And use method CheckFlag() to check flag. In this example I use FileSystemWatcher to catch all file changes and call SetFlag() and CheckFlag() inside the handler of event Changed

Instead of button1.PerformClick() you can use button1_Click(this, EventArgs.Empty)

First of all, I would set the interval to something like 500, then step it back to 400, 300, 200, 100, etc. until you get the desired speed you want.

Secondly, assuming Label2 is your max value and Label3 is your min value and that you want your progress bar control to simply bounce back and forth between the min and max values, I would do something like this:

Const MAX_VALUE = 100 Const MIN_VALUE = 0 Dim currentValue = 0 Dim isIncrementing = True Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick If currentValue = MAX_VALUE Then isIncrementing = False If currentValue = MIN_VALUE Then isIncrementing = True If isIncrementing Then currentValue += 1 Else currentValue -= 1 ProgressBar1.Value = currentValue ProgressBar1.Update() End Sub

Since I'm assuming your Label2 and Label3 are your min/max values, I'm also assuming they should stay static and never change, which is why I don't change their values in the Tick event. If you wanted a Current Value label, that would be easy enough to add and that would be changed at the same time the ProgressBar1.Value is.

Regex has a thing called a "non capturing negative lookahead assertion" which basically says "don't match the following". It looks like this:

^people/(?!People_Search)([A-Za-z0-9\-\_]+)/?$

Whether you can use this depends on the rewrite engine you use, and the level of regex support that's included in it. I'd expect that most common rewriters support this.

FYI: There are also negative lookbehind assertions(?<!), and also postive versions of the lookahead (?=) and lookbehind (?<=) assertions.

38083634 0 Android sign in with Google APIs expires very early

I followed these guidelines to integrate Google sign-in into my android app: https://developers.google.com/identity/sign-in/android/sign-in#start_the_sign-in_flow

When activity's onStart is called, it tries to sign-in again, if required information is cached and present on device, without any Internet connection.

The problem is that it expires at almost 5 hours. And Google APIs requires Internet connection to sign in again.

How can I increase offline persistence of sign-in information?

6052881 0 Archiving large amounts of old data in SQL Server

Pretty simple question.

I have a large 70gb database that has four of five tables that contain about 50 million rows each. These tables contain about 6 years worth of data. We are limited to amount of space in our database to 80gb, and we are going to be quickly approaching that in the next 6 months or so.

We only need to keep about two years worth of data in the live database. What is the best approach to archiving the older data WITHOUT taking the live database offline (it's 24/7 database)?

We are running SQL Server 2008 R2 Standard in a clustered environment using active-passive setup using shared storage.

Thanks.

I know it's so late but I had the same problem, so here's the solution below:

To create web.xml:

Right click on your project
Choose New
Choose Other
Box New file is opened, in Filter search web.xml
You will get the file you want web.xml, then click next...then finish

Honestly, I find IDEA scarily good at reading my mind of what method I want to call next. And it usually just takes a couple letters for it to narrow down what I'm looking for pretty precisely.

But, I think what you may be looking for is the "Sort lookup items lexicographically" option, in the Settings window under Editor / General / Code Completion. This always sorts the list by the name, rather than by predicting a few things to put at the top.

You can read more about it and the other code completion options in the IntelliJ IDEA documentation.

I have the answer. Apparently jQuery doesn't support the default behavior of links clicked programmatically

Creating and submitting a form works really well though (tested in Chrome 26, FF 20 and IE 8):

var form = $("<form></form>"); form.attr( { id : "newform", action : "https://google.nl", method : "GET", target : "_blank" // Open in new window/tab }); $("body").append(form); $("#newform").submit(); $("#newform").remove();

What it does:

Create a form
Give it attributes
Append it to the DOM so it can be submitted
Submit it
Remove the form from the DOM

Now you have a new tab/window loading "https://google.nl" (or any URL you want, just replace it). Unfortunately when you try to open more than one window at once this way, you get an Popup blocked messagebar when trying to open the second one (the first one is still opened).

3451451 0 Why do people spend so much time searching for, and hacking around with, "free" toolsets when superior pay ones are available?

Clarification: I'm referring to companies that pay developers, professionally. I understand why a "hobby" or "for fun" developer wouldn't want to (or couldn't afford) a fully-features pay tool, and may prefer to tinker. I'm talking about situations where a deadline is bearing down on a developer/company and development time is diverted away from the goal in pursuit of a "Free" tool to accomplish what a pay one is available to do.

I've noticed a number of Stack Overflow questions recently (they're not new, I've just recently taken notice) where people are searching for free alternatives to popular development tools for things like ALM, database comparison, and other functions for which there's a trivially costly pay alternative. The "Free" tag on Stack Overflow has 350 questions, and it doesn't take long to see dozens of examples of "Is there a FREE tool to do X?" followed by discussions that must have taken the asker hours to research and participate in.

It's not just about paying less - I'm often amazed at the hoops that some developers (or, perhaps more accurately, their companies) will go through to avoid paying for something - in some cases, a pay solution will be avoided in favor of a poorly documented, buggy, feature-incomplete open-source solution that results in dozens of hours of work that could have been avoided.

I understand the most obvious reasons:

Company is short on cash
Don't pay for something when a (functionally-comparable) free alternative is available
"Hobby" developers don't have the cash to spare, and since they're just learning, it doesn't make sense to pay for a toolset they're only tinkering with

However, I think the "short on cash" reasoning is completely bogus - as a developer not long out of college, I made about $50K annually, or $200/day (meaning my company probably paid close to $300/day to have me in my chair, all considered). When you compare that price to a $300 tool, the obvious answer is "if it's going to waste more than a day of your time, you should buy it instead and get back to work". However, that's not what I observe - people seem willing to kill dozens of hours to avoid paying for something that only costs $50.

Help me understand - as a developer myself of tools I'd like to one day sell, I want to understand the mentality. Have I been spoiled by working at a company that's not afraid to spend? Is there an ingrained reason developers (or their companies) don't want to spend money? Can people not accurately estimate the costs of "Free" tools in terms of lost productivity?

I'm not referring to instances where a great free alternative is available. For example, any of these tools is a great example of something you shouldn't pay for. However, let's say one of those lacks a key feature you need, and which a pay version of the same library provides - people seem to lean towards hacking around with the free version to add the needed functionality (or scaffold in the needed functionality) instead of ditching the free tool in favor of the pay (and feature-complete) version. I'm not saying that's the wrong choice, but it's just a choice I want to understand the reasoning to. The important point is that I'd like to - my intent is not to be argumentative.

Create new iterator

 bson_iterator nInterat[1];

below subit iterator

bson_iterator subit[1]; bson_iterator nInterat[1];

instead of this

bson_iterator_subobject_init(subit, sub_Object,1)

change like

bson_iterator_subobject_init(nInterat, sub_Object,1) if(bson_find(nInterat, sub_Object, "name")) printf("\tName : %s\n", bson_iterator_string(nInterat)); if(bson_find(nInterat, sub_Object, "telephone")) printf("\tTelephone: %s\n", bson_iterator_string(nInterat));

because your subit iterator is overwrite with current sub_object Index

36924214 0 Identify and count array duplicates

I have the following array:

var newOrderItems = [Order]()

that holds Order type elements:

let order = Order(item: itemName, quantity: 1) newOrderItems.append(order!)

At some point newOrderItems holds:

[ Order("item1", 1), Order("item1", 1), Order("item2", 1), Order("item2", 1), Order("item3", 1), Order("item1", 1) ]

I need to identify and count duplicate Order array elements so that I form a string message such as:

"You have ordered 3 x item1, 2 x item2, 1 x item3".

Is there a simple way for this? My solution(s) either add way too much overhead (i.e nested loops), or too much complexity (i.e. unique NSCountedSet) for something that I expect to be trivial.

36883973 0 html5 multiple file upload with spring mvc 4 and spring boot

I'm trying to upload multiple files using spring mvc 4, spring boot and thymeleaf as template engine, but i'm not able to access the uploaded files, the files are dealt with as one multipart file with content type application/octet-stream. here's my front-end code:

 <form name="offer-form" th:action="@{/submit-property}" method="POST" enctype="multipart/form-data"> <!-- .. other inputs .. --> <div class="col-xs-12 margin-top-60"> <input id="file-upload"name="files[]" type="file" multiple="multiple"/> </div> <div class="col-xs-12"> <div class="center-button-cont margin-top-60"> <button type="submit" class="button-primary button-shadow"> <span>submit property</span> <div class="button-triangle"></div> <div class="button-triangle2"></div> <div class="button-icon"><i class="fa fa-lg fa-home"></i></div> </button> </div> </div> </form>

And the controller code:

the output of the sysout:

uploadedImages length: 1 (even though i upload multiple files)

File Original Name (using getOriginalFileName):

File Name (using getName): files[]

File size: 0

File Content type: application/octet-stream

and then an exception when subsctring is called on the empty original file name.

I tried to add commons file upload to my POM and configured CommonsMultipartResolver bean, but then it always prints that there are no uploaded images (which means it's null or length=0)

If I understood well, you would like include the code from includefile.php into your test.php ?

You can't use include like that, but you should do it like that.

file_put_contents($file, file_get_contents('includefile.php'), FILE_APPEND);

This will append the content from includefile.php into your test.php

I asked what I thought was a different question, but it turned out to have the same answer as this one: raw data from CVImageBuffer without rendering?

10311565 0

As I understand the problem this will work:

SELECT t.value, t.from_id, t.to_id, t.loop_id FROM MyResults t INNER JOIN ( SELECT From_ID, To_ID, MIN(Value) [Value] FROM MyResults WHERE Loop_ID % 2 = 0 GROUP BY From_ID, To_ID ) MinT ON MinT.From_ID = t.From_ID AND MinT.To_ID = t.To_ID AND MinT.Value = t.Value

However, if you had duplicate values for a From_ID and To_ID combination e.g.

value from_id to_id loop_id ------------------------------------- 0.1 A B 2 0.1 A B 4

This would return both rows.

If you are using SQL-Server 2005 or later and you want the duplicate rows as stated above you could use:

SELECT Value, From_ID, To_ID, Loop_ID FROM ( SELECT *, MIN(Value) OVER(PARTITION BY From_ID, To_ID) [MinValue] FROM MyResults ) t WHERE Value = MinValue

If you did not want the duplicate rows you could use this:

SELECT Value, From_ID, To_ID, Loop_ID FROM ( SELECT *, ROW_NUMBER() OVER(PARTITION BY From_ID, To_ID ORDER BY Value, Loop_ID) [RowNumber] FROM MyResults ) t WHERE RowNumber = 1

You are experiencing a side-effect from i++ which puts you at the mercy of the optimizer which has some leverage as to when to do the increment the way you wrote the code. To be safe, do

data[i] = temp[i]; i++;

After getting the value for "findText", you can get the text value of the var by

 var findTextValue = findText.asText();

and then change the background of that text in the body.

You can possible write a recursive function to find the #placeholder# and change the background color.

Try checking this question already been answered by Mogsdad for more details.

Hope that helps!

You can either use Attribute routing (specified as an attribute, either on the entire controller class or each method individually) or conventional routing. If each controller can have multiple possible endpoints, it may be harder to achieve what you want through attribute routing, albeit still possible. If you choose to go the conventional route (pun intended), you could set that up similar to this way:

Adapted from the Web API 2 docs:

 public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Attribute routing. config.MapHttpAttributeRoutes(); // Convention-based routing. config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{endpointId}/{controller}/public/{category}/{id}", defaults: new { endpointId = "1", controller = "DefaultController", category = "DefaultCategory" id = RouteParameter.Optional } ); } }

38395747 0 Bootstrap same height cards within cols

With Bootstrap 3.3.6 I want to make 3 cards.

<div class="row"> <div class="col-md-4"> <div class="card"> <p>Some dummy text here</p> <button>Click Here</button> </div> </div> <div class="col-md-4"> <div class="card"> <p>Some dummy text here</p> <button>Click Here</button> </div> </div> <div class="col-md-4"> <div class="card"> <p>Some dummy text here</p> <button>Click Here</button> </div> </div> </div> .card { border: 1px solid #ddd; border-radius: 5px; padding: 20px; }

Now that the Dummy text is not the same length, the cards will not be the same height.

I found a trick using flexbox here: How can I make Bootstrap columns all the same height?, but this will be working on the immediate children of the .row not the .card

Another thing, even if the cards will be the same height, the buttons will not be on the same line as they will follow the the text.

While they weren't allowed in c89, they are allowed now. The main difference between the two is the number of lines your comment needs. But generally:

int x = 0 // This comment can be used for quick descriptions. /* * This kind of comment should be used for multiple lines * that take more than 3 lines. */

In the end, it all depends what you prefer, but this is general convention that I've seen on how to use each comment.

You can't disable cookies only on your web browser control. The control is essentially an embedded Internet Explorer and shares the user's Internet Explorer settings. If you don't mind blocking cookies on all other instances of Internet Explorer (maybe you use Chrome or Firefox for the rest of your browsing) you can do the following:

(From: http://social.msdn.microsoft.com/Forums/en-US/winforms/thread/90834f20-c89f-42f9-92a8-f67ccee3799a/)

To block Cookies in WebBrowser control you can take the following steps, in fact, it's the same as to block Cookies in IE.

Choose "Internet Options" under the "Tools" menu on the IE;

Select the "Privacy" tab.

Click the "Advanced..." button in the "Settings" groupbox.

Check the "Override automatic cookie handling" option.

Check both "Block" options.

Click "OK"

You could also delete all the cookies after you visit a page, but I don't think this will fulfill your goal of being completely anonymous.

I did a little digging and I think you can use InternetSetOption and the INTERNET_SUPPRESS_COOKIE_PERSIST flag. According to the documentation, this will only work for Internet Explorer 8 and later.

private const int INTERNET_OPTION_SUPPRESS_BEHAVIOR = 3; //INTERNET_SUPPRESS_COOKIE_PERSIST - Suppresses the persistence of cookies, even if the server has specified them as persistent. [DllImport("wininet.dll", SetLastError = true)] private static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength);

Then when you initialize your app try:

InternetSetOption(IntPtr.Zero, INTERNET_OPTION_SUPPRESS_BEHAVIOR, IntPtr.Zero, 0);

Hopefully this puts you on the right track. See also:

First of all you will need to install some dependencies: matplotlib and numpy.

The first option is to use matplotlib animation like in this example:

import numpy as np import matplotlib.pyplot as plt import matplotlib.animation as animation def update_line(num, data, line): line.set_data(data[..., :num]) return line, fig1 = plt.figure() data = np.random.rand(2, 25) l, = plt.plot([], [], 'r-') plt.xlim(0, 1) plt.ylim(0, 1) plt.xlabel('x') plt.title('test') line_ani = animation.FuncAnimation(fig1, update_line, 25, fargs=(data,l),interval=50, blit=True) plt.show()

A more mathematical option is this one:

import matplotlib.pyplot as plt import numpy as np import time x = np.linspace(0, 1, 20) y = np.random.rand(1, 20)[0] plt.ion() fig = plt.figure() ay = fig.add_subplot(111) line1, = ay.plot(x, y, 'b-') for i in range(0,100): y = np.random.rand(1, 20)[0] line1.set_ydata(y) fig.canvas.draw() time.sleep(0.1)

I hope this is what you were searching for.

I would recommend against following the push paradigm that is suggested above and switch to the pull paradigm. The purpose of AWSIdentityProviderManager is to prompt you for a token only when the SDK needs it, not for you to set it externally periodically whether the SDK needs it or not. This way you don't have to manage token expiry yourself, just make sure your token is valid when logins is called and if it isn't you can use an AWSCompletionSource to get a fresh one.

Assuming you have integrated Facebook login, your IdentityProviderManager should look something like this:

import Foundation import AWSCore import FacebookLogin import FacebookCore class FacebookProvider: NSObject, AWSIdentityProviderManager { func logins() -> AWSTask<NSDictionary> { if let token = AccessToken.current?.authenticationToken { return AWSTask(result: [AWSIdentityProviderFacebook:token]) } return AWSTask(error:NSError(domain: "Facebook Login", code: -1 , userInfo: ["Facebook" : "No current Facebook access token"])) } }

To use it:

let credentialsProvider = AWSCognitoCredentialsProvider(regionType: AWSRegionType.YOUR_REGION, identityPoolId: "YOUR_IDENTITY_POOL_ID", identityProviderManager: FacebookProvider()) let configuration = AWSServiceConfiguration(region: AWSRegionType.usEast1, credentialsProvider: credentialsProvider) AWSServiceManager.default().defaultServiceConfiguration = configuration

And then to test getting credentials:

AWSServiceManager.default().defaultServiceConfiguration.credentialsProvider.credentials().continue(with: AWSExecutor.default(), with: { (task) -> Any? in print(task.result ?? "nil") return task })

BTW, I needed to add this to my app delegate to get Facebook Login to work with Swift which is not mentioned in the instructions here https://developers.facebook.com/docs/swift/login :

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as!

I've been trying to replicate your problem but with no luck.

Activating virtualenv leaves me with a prompt like this:

jeff@DeepThought:~$ source ~/ENV/bin/activate (ENV)jeff@DeepThought:~$

Mostly what this is doing is adding the ~/ENV/bin to the front of the search path so when I type "python" the version I have installed in that bin comes up first. In my case, I have 2.6 installed globally and 2.7 installed virtually.

(ENV)jeff@DeepThought:~$ python Python 2.7 (r27:82500, Sep 8 2010, 20:09:26) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>

What I find strange about your case is that you say you have your updated libraries in the virtual environment, but you are only able to access them with python2.6. Unless you have created it on your own, ~/ENV/bin should not even have a python2.6 executable. If you have activated virtualenv, typing python should bring you to the virtualenv python shell and typing python2.6 would bring you to the global python shell. If that were the case, you should be seeing the opposite of what you say is happening.

The first thing I would do is check out what is being executed when you run python and python2.6:

(ENV)jeff@DeepThought:~$ which python /home/jeff/ENV/bin/python (ENV)jeff@DeepThought:~$ which python2.6 /usr/bin/python2.6

This looks how I would expect it to. What does yours look like? If yours also looks like that, maybe you need to just go into ~/ENV/lib/python2.6/site-packages/ and remove the files that are giving you trouble, replacing them with the updated files.

EDIT: alias takes priority over search path:

jeff@DeepThought:~$ echo $PATH /home/jeff/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games jeff@DeepThought:~$ cat > /home/jeff/bin/hello.sh #!/bin/bash echo "hello world" jeff@DeepThought:~$ chmod +x ~/bin/hello.sh jeff@DeepThought:~$ hello.sh hello world jeff@DeepThought:~$ which hello.sh /home/jeff/bin/hello.sh jeff@DeepThought:~$ alias hello.sh=/usr/bin/python jeff@DeepThought:~$ which hello.sh /home/jeff/bin/hello.sh jeff@DeepThought:~$ hello.sh Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>

public bool Execute_InsertQuery(string _query, SqlParameter[] param) { try { SqlCommand cmd = new SqlCommand(); cmd.Connection = OpenConnection(); cmd.CommandText = _query; cmd.Parameters.AddRange(param); cmd.ExecuteNonQuery(); return true; } catch (Exception ex) { Console.Write(ex.StackTrace.ToString()); return false; } }

Update for getting Error : I tried to pass all parameters in this manner :

dbConnection c = new dbConnection(); System.Data.SqlClient.SqlParameter[] param = new System.Data.SqlClient.SqlParameter[15]; param[0] = new SqlParameter("@Username", "hakoo"); param[1] = new SqlParameter("@Password", "hakoo"); param[2] = new SqlParameter("@UserType", "User"); param[3] = new SqlParameter("@FirstName", "Hakoo"); param[4] = new SqlParameter("@LastName", "Hakoo"); param[5] = new SqlParameter("@DateOfBirth", "02/11/88"); param[6] = new SqlParameter("@Gender", ""); param[7] = new SqlParameter("@Unit_No", null); param[8] = new SqlParameter("@St_No", 25); param[9] = new SqlParameter("@St_Name", "anc st"); param[10] = new SqlParameter("@Suburb", "ancst"); param[11] = new SqlParameter("@State", "assadd@few"); param[12] = new SqlParameter("@Postcode", 2615); param[13] = new SqlParameter("@Email", "abc@def.com.au"); param[14] = new SqlParameter("@Phone", "165103548"); c.Execute_InsertQuery("dbo.Insert_tblCustomer", param);

But for this, I am getting this error :

I don't think performance will be much of a problem. Just save the data in a database, which will provide you with the easiest way for your structure.

Even after the first letter of the main place is pressed, it already drastically reduces possibilities.

Going from sub place --> main place, you could put the treshhold before showing the option list a bit higher.

24769785 0 More efficient way of running multiple update queries on an Access database?

I have multiple queries like this right now which involve updating different fields of the same row in an Access database:

PHP is a server-side language and you won't be able to load it up in a web browser just like that. You'll have to use a web server, like WAMP or XAMPP for example.

Make sure of these things first:

that PHP is installed and running on your computer
that the file extension is .php
that you're accessing the php file with something like localhost/yourfile.php and not file://yourfile.php
that the permission for your files is correct (644 or 755 would be enough, I think)

Hope this helps.

From your description, I can see that you are trying to query information from Windows SNMP service.

Unfortunately that Microsoft thinks WMI is more suitable for its products, so its SNMP implementation is too simple to provide you all the information you need. You either need to switch to WMI, or have to extend its SNMP agent (via custom modules).

Therefore, if you are seriously deciding to develop an application for your requirements, consider WMI as the preferred approach, not SNMP.

16255864 0 uncrustify adds space between double-paranthesis (C/Objective-C)

I'm having a very peculiar issue with uncrustify (v0.60) that no option seems to affect. The issue only occurs when there are parenthesis enclosed within parenthesis:

// from a C header file: #define BEGIN_STACK_MODIFY(L) int __index = lua_gettop( (L) ); ^ ^ // from an ObjC (.m) implementation file: if ( (self = [super init]) ) ^ ^

I want to reformat those to look like this, but uncrustify always adds those spaces between parenthesis (when I manually reformat to the code below, uncrustify will reformat it to the version above, so it's not just being ignored by uncrustify):

// from an ObjC header file: #define BEGIN_STACK_MODIFY(L) int __index = lua_gettop((L)); // from an ObjC (.m) implementation file: if ((self = [super init]))

I used UncrustifyX to check all (well, a great number of) variations of possibly related settings for spaces and parenthesis with no luck.

You can check my uncrustify config file here on gist.

If you have any idea what settings I should try, or perhaps settings that may be in conflict with each other, I'd be happy to test it.

3770874 0 How to return selected items from checkboxlist control in asp.net

I am trying to return in a string the selected items from a dynamically bound checkbox list control with no luck. I'm hoping someone can help. In my code behind file I am conencting to a class called users and building a datatable. I then bind the data table to the cblist control

 private void populateUserList() //called on page load { SubmitOptions mySubmission = new SubmitOptions(juris, rptType, tmplName); if (mySubmission.Users.Count == 0) { lbl_juris.Visible = false; cb_selectUser.Visible = false; lbl_AlertMsg.Visible = true; btnSelect.Visible = false; lbl_AlertMsg.Text = "No supervisors listed for jursidiction: " + juris.ToString(); } else { dt.Columns.Add("Users"); for (int i = 0; i < mySubmission.Users.Count(); i++) { DataRow dr = dt.NewRow(); dr["Users"] = mySubmission.Users[i]; dt.Rows.Add(dr); } cb_selectUser.DataSource = dt; cb_selectUser.DataBind(); } }

Within the main aspx file I have the control defined as:

<asp:CheckBoxList ID="cb_selectUser" Width="400px" Height="100%" AutoPostBack="false" runat="server" CellPadding="2" CellSpacing="5" DataTextField="Users" DataValueField="Users" > </asp:CheckBoxList>

I have tried the following code where i itterate through the list but this only seems to work if I hard code values into the Checkboxt list as listitems.

 protected void btn_returnUserList(object sender, System.Web.UI.ImageClickEventArgs e) { for (int i = 0; i < cb_selectUser.Items.Count; i++) { if (cb_selectUser.Items[i].Selected) { selectedUsers += cb_selectUser.Items[i].Text; } }

The list populates fine and all I want to do is return in a string all selected users from the checkbox list control.

As I said if I hard code the item values into the control the above code works and I can see the selected items in the string however removing the itemslist tags and switching over to a binding nothign happens. The above method counts the entire number of returns but nothing selected is ever returned.

Any tips or suggestions as to what I am missing would be greatly appreciated.

If you examine the code you see that when the UIAlertView is being created it is being allocated too. So the retain count of the alert is 1 after that. If you read the apple documentation you will see that the [alert show] also increase the retain count of the UIAlertView. So, after that line the retain count will be 2. The line [alert release] will decrease the retain count to 1 again, because, for this code, isn't important to keep reference to the UIAlertView. So, after that, the retain count is 1, and the UIAlertView is being showed. When the user press the button to close the alert, the method that closes the alert will decrease the retain count to 0 and the memory will be freed

Yes this is possible, you simply have to specify the transport when initializing the Bus:

 var config = Configure.With() .SpringBuilder() .AzureConfigurationSource() <--- Don't use this when working on premise. .XmlSerializer() .UnicastBus() .LoadMessageHandlers() .AzureQueuesTransport() <--- Configure Azure Storage Queues .IsTransactional(true) .PurgeOnStartup(false) .InMemorySubscriptionStorage();

For the documentation part, I suggest you take a look on github: https://github.com/NServiceBus/NServiceBus/tree/master/Samples/Azure

Note that most of these samples are meant to run in Windows Azure, hence the use of the AzureConfigurationSource. This won't work when you're running on premise since it uses settings from the RoleEnvironment. Don't use AzureConfigurationSource when working on premise.

29585461 0 SOIL load image with incorrect color

In my opengl program, I use SOIL to load texture, and the code is like below:

 m_objTexture = SOIL_load_OGL_texture ( fileName.c_str(), SOIL_LOAD_AUTO, SOIL_CREATE_NEW_ID, SOIL_FLAG_MULTIPLY_ALPHA | SOIL_FLAG_TEXTURE_REPEATS );

But what's weired is that the color of the loaded texture seems not identical to the image sometimes (But sometimes it behaves fine). For example, the original image is shown below:

enter image description here

But when I debug in nsight studio, I can see the buffer of the texture object is like this:

enter image description here

Obviously the color is very different from the original image. In this example, the texture is a 24bit jpg file (249 x 250). I wonder is there anything that I missed for texture loading with SOIL?

Per the MSDN documentation the valid values for mode are:

On: Specifies that custom errors are enabled. If no defaultRedirect attribute is specified, users see a generic error. The custom errors are shown to the remote clients and to the local host.

Off Specifies that custom errors are disabled. The detailed ASP.NET errors are shown to the remote clients and to the local host.

RemoteOnly Specifies that custom errors are shown only to the remote clients, and that ASP.NET errors are shown to the local host. This is the default value.

The default is RemoteOnly.

Ok, here's the scoop. QTimer, for reason only known to the designers of QT, inherits the context of the parent of the thread. Not the context of the thread it's launched from. So when the timer goes off, and you send a message from the slot it called, you're not in the thread's context, you're in the parents context.

You also can't launch a thread that is child of THAT thread, so that you can fire a timer that will actually be in the thread you want. Qt won't let it run.

So, spend some memory, make a queue, load the message into the queue from elsewhere, watch the queue in the thread that owns the TCP port, and send em when ya got em. That works.

What you need is an inner join and a left join. Like so...

select g.name, v1.name, v1.location, coalesce(v2.name, 'NULL'), coalesce(v2.location, 'NULL') from groups g inner join venues v1 on (g.pri_venue_id = v1.venue_id) left join venues v2 on (g.alt_venue_id = v2.venue_id)

The coalesce function basically just converts null values into the string NULL

Yes this is possible. But one class needs to know the other class. Try it like this:

Hope this helps.

What compiler did you use, I'm willing to bet this worked because whatever compiler you used didn't zero out unused stack variables after a return, you didn't get a seg fault because its still your stack. basically md was left on the stack which you are technically still allowed to address. The difference between the two is

largeObj md;

is a variable receiving a variable in its entirety.

largeObj& mdd = iReturnLargeObjects();

is a reference to a variable that due to a lazy compiler still exists.

So very simply put. netRead gets info from another function that is very basic. Then the switch goes through the net_step int...

After the game has received all the packets needed to continue, we trigger the nextGameUpdate() and send it 3 arrays and a dataSize int variable.

I am a beginner on Android development and I came into a problem which I hope you can help me to solve. I'll keep it simple...i am trying to use Google Places autocompletion in a fragment...the app stops right from the beginning. My guess is the problem is when I use the method rebuildGoogleApiClient() and when I set up the PlaceAutocompleteAdapter after that. Here is my code:

(PlaceAutocompleteAdapter - Adapter that handles Autocomplete requests from the Places Geo Data API )

 public class PlaceAutocompleteAdapter extends ArrayAdapter<PlaceAutocompleteAdapter.PlaceAutocomplete> implements Filterable { LatLngBounds mBounds; AutocompleteFilter mPlaceFilter; //constructor public PlaceAutocompleteAdapter(Context context, int resource,LatLngBounds bounds, AutocompleteFilter filter) { super(context, resource); mBounds = bounds; mPlaceFilter = filter; } }

Is MyKey actually immutable?

If a key is changed after it has been used in the Multimap (or a HashMap, for that matters), and the change effects hashCode() and equals(), you won't be able to find the associated values anymore: the modified hashcode means the lookup does not happen in the bucket where the values were stored.

You can use regular expressions to match any of the bad words:

is_bad = re.search('|'.join(bad_words), bad_string) != None

bad_string is the string to test, is_bad is True or False, depending on whether bad_string has bad words or not.

Assuming this data structure:

$links = array( array( "g2m_via-title" => "JoyStiq", "g2m_via-link" => "joystiq.com" ), array( "g2m_via-title" => "GrindGadget", "g2m_via-link" => "grindgadget.com" ), array( "g2m_via-title" => "Engadget", "g2m_via-link" => "engadget.com" ) );

This'll do:

$output = array(); foreach ($links as $link) { $output[] = sprintf('<a href="http://%s">%s</a>', $link['g2m_via-link'], htmlentities($link['g2m_via-title'])); } echo join(', ', $output);

So will this in PHP 5.3+:

echo join(', ', array_map(function ($link) { return sprintf('<a href="http://%s">%s</a>', $link['g2m_via-link'], htmlentities($link['g2m_via-title'])); }, $links));

Does your TableAdapter refresh your DataSet? If it does, then you probably have something like a key getting initialized (remember, GUID==good, Int==bad). It's just like when you fill from a TableAdapter you need to call AcceptChanges to reset the state of all of the rows to unchanged.

33103263 0 Android MediaPlayer with LocalSocket not working

I am trying to play media from LocalSocket using MediaPlayer. The stream is of type MPEG-TS, which is availale in a LocalSocket input stream

Following code tries to setDataSource to the FileDescriptor of LocalSocket, but failes.

LocalSocket wsIns = fileThread.getReadSocket(); p = new MediaPlayer(); p.setDisplay(holder); FileDescriptor fd = wsIns.getFileDescriptor(); Log.e("TS","is valid ? "+fd.valid()); p.setDataSource(fd ,0, fileThread.getLength());

setDataSource fails with following exception.

10-13 17:21:31.510: W/System.err(6472): java.io.IOException: setDataSourceFD failed.: status=0x80000000 10-13 17:21:31.510: W/System.err(6472): at android.media.MediaPlayer.setDataSource(Native Method) 10-13 17:21:31.510: W/System.err(6472): at com.example.test.TSRenderActivity.surfaceCreated(TSRenderActivity.java:94)

The debug logs suggest that the error is primarily due to this, where fstat on the LocalSocket's file descriptor returns size of the file as 0.

But if I try wsIns.getInputStream().available() this api gives non zero number of bytes available.

Note : The same error on using p.setDataSource(fp);

If you're looking to merely modify the image as it's displaying on screen, here's a tutorial on using HLSL (Pixel shaders) in WPF and one specifically for brightness and contrast

If you're looking for how to manipulate the images in memory and save them to disk, I'll need to look harder, but I'm sure I can come up with something. :)

The only thing I personally would have done differently is:

Use EF (but yeah, L2S is fine for a quickie like this)
Create a ViewModel class for the details View. I use ViewData as sparingly as possible.

But yeah, nothing bad here and I agree that it was probably not a good place to work at. People also tend to make up vague reasons if they didn't want to say they didn't like your face.

I would prefer the one with RationalMath. You really don't need extension methods here, because their aim is to mimic instance methods of objects of you can't modify. But here one should use plain old static method.

In addition to the other answers, don't forget that casting might fail where Floor would succeed:

decimal d = decimal.MaxValue; decimal f = Math.Floor(d); // succeeds long l = (long)d; // fails

34364188 0

Assuming you want to add the result z from each method:

static int number1(){ int x, y, z; x=2; y=2; z=x+y; return z; } static int number2(){ int x, y, z; x=3; y=2; z=x+y; return z; }

You could simplify this though to a more generic method:

static int adder(int a, int b) { return a + b; } public static void main (String [] args){ p = adder(2, 2) + adder(3, 2); }

31561644 0 Why doesn't this function load after a successful ajax call in jquery?

I'm using the tutorial here, that used to work last month, but now it isn't. I've copied the relevant code below.

$(document).ready(function () { $.ajax({ type: "GET", url: "http://papermashup.com/demos/jquery-xml/books.xml", dataType: "xml", success: xmlParser }); alert("123"); }); function xmlParser(xml) { alert("456"); $('#load').fadeOut(); $(xml).find("Book").each(function () { $(".main").append('<div class="book"><div class="title">' + $(this).find("Title").text() + '</div><div class="description">' + $(this).find("Description").text() + '</div><div class="date">Published ' + $(this).find("Date").text() + '</div></div>'); $(".book").fadeIn(1000); }); }

The problem is that the xmlParser() function isn't being called after the successful ajax request. It shows a 123 alert but not a 456 alert. Am I doing something wrong, or is the tutorial wrong?

I've included a relevant jsfiddle here. http://jsfiddle.net/desbest/nwt3unxu/

From what I understood from your problem, you seem to have OneToMany relationships in this manner:

public class Project { ... @OneToMany List<Expense> expenses; @OneToMany List<Income> incomes; ... }

Lets suppose your database structure is like this;

Project

id name 1 helloWorld

project_income

proj_id income_id 1 1

project_expense

proj_id expense_id 1 1 1 2

income

id amount 1 200

expense

id amount 1 500 2 600

Your query produces result in this manner

proj_id proj_name income_id income_amount expense_id expense_amount 1 helloWorld 1 200 1 500 1 helloWorld 1 200 2 600

and so when you sum incomeAmount and expenseAmount, you get a result like this:

proj_id proj_name sum(income_amount) sum(expense_amount) 1 helloWorld 400 1100

Because of this, when you sum incomeAmount and expenseAmount, you (sometimes) get double or triple values. Its the nature of join statements. You may wanna take a look as to what is inner and outer joins and how do they produce results.

To get the desired results, one (one of the many available) solution is that you can use multiple select statements as shown below:

Query query = session.createQuery( "select p.projectId, " + "p.projectName, " + "(select sum(i.incomeAmount) from Income i where i.incomeProject = p), " + "(select sum(e.expenseAmount) from Expense e where e.expenseProject = p), " + "from Project as p" + "group by p.projectId, pi.investorId ") .setFirstResult(firstResult) .setMaxResults(maxResult);

Output:

proj_id proj_name sum(income_amount) sum(expense_amount) 1 helloWorld 200 1100

I hope it helps.

You're on the right track using dimensions. Make a different values folder for each screen size you'd like to support, ie values-sw320dp, values-sw600dp, etc. Each with its own dimens.xml file. Then, put different values for leftMargin, topMargin, etc in each dimens file. Look at the section "Using new size qualifiers" here for more info.

Your mistake is here:

while(right->next != NULL){ right = right->next; }

You are trying to check "right->next" where "right" is NULL.

You have a dangling reference. You had an object that responded to the text message. You deallocated it but you still have a reference to it somewhere. You reused the memory of that deallocated object to create an NSMutableArray, then sent the text message through the dangling reference.

XML loves recursion. It's a lot of work to lay out the nodes one-by-one or into some gigantic table grid -- your data format is heirarchical and your processing method should be as well.

Yep. Tried it. I'm just having trouble getting my mind around the best way to do it. I could use tables. I could use css. Absolute positioning. But nothing I come up with in HTML is really working for me.

XSLT is pretty good at transforming xml into html. the following xslt transforms your xml into a series of nested divs and tables. I'm using a table to get each colleague group aligned. seemed like the easiest way.

<xsl:template match="employee"> <div class="wrapper"> <div class="smallline" /> <div class="box"> <xsl:value-of select="name"/> <br/> <xsl:value-of select="title"/> </div> <xsl:if test="directReports/employee"> <div class="smallline"> </div> <table> <tr> <xsl:for-each select="directReports/employee"> <td> <xsl:apply-templates select="." /> </td> </xsl:for-each> </tr> </table> </xsl:if> </div> </xsl:template>

To preview, save the xslt from http://pastebin.com/f6597d519

Add <?xml-stylesheet href="foo.xslt" type="text/xsl"?> to the top of your employees xml, and open in a browser. In practice, you may want to transform on the server to avoid compatibility issues. To do that in C#, see How to apply an XSLT Stylesheet in C#

The web browser is expecting some javascript to be executed after the ajax has been called. Your code should work when javascript is disabled in the browser.

In the add_new_message method you should add:

respond_to do |format| format.html { redirect_to(:action => 'index') } format.js end

Then some javascript in add_new_message.js.erb will be executed, so to redirect to the index, the code in add_new_message.js.erb should look like:

window.location = '<%= forums_path %>'; //or whatever other path

Although both the HTML and javascript do the same thing. Why is the ajax needed in the first place?

38652756 0 R: Removing unwanted `Variables sorted by number of missings:` from Graph

I am using the VIM package in R to plot missing values. I want to sort by number of values in the chart but dont want to see the section Variables sorted by number of missings:. The parameter sortVars=TRUE, is responsible for both the output and the sorting. Its useful for exploratory analysis but i want to use the output in a document using rmarkdown

Does anyone know how to implement this. It would be better explained with the code below

set.seed(300) Q <- c(1,2,3,4,5,6,NA) mydf <- data.frame(participent = (1:100), A1 = sample(Q,100,replace=TRUE), A2 = sample(Q,100,replace=TRUE), A3 = sample(Q,100,replace=TRUE), B1 = sample(Q,100,replace=TRUE), B2 = sample(Q,100,replace=TRUE), B3 = sample(Q,100,replace=TRUE), C1 = sample(Q,100,replace=TRUE), C2 = sample(Q,100,replace=TRUE), C3 = sample(Q,100,replace=TRUE) ) # Missing Values sorted by volume with unwanted output aggr_plot <- aggr(mydf, col=c('lightgrey','darkgreen'), numbers=FALSE, sortVars=TRUE, combined = TRUE, only.miss = TRUE, labels=names(mydf), cex.axis=.45, plot = TRUE) # Missing Values sorted by volume without unwanted output aggr_plot <- aggr(mydf, col=c('lightgrey','darkgreen'), numbers=FALSE, sortVars=FALSE, combined = TRUE, only.miss = TRUE, labels=names(mydf), cex.axis=.45, plot = TRUE)

Another alternative, assuming your elements are stored as variables (which is often a good idea if you're accessing them multiple times in a function body):

function disableMinHeight() { var $html = $("html"); var $body = $("body"); var $slideout = $("#slideout"); $html.add($body).add($slideout).css("min-height", 0); };

Takes advantage of jQuery chaining and allows you to use references.

8552333 0 Normalizing string for arithmetic expression evaluation in Java

I have a method that evaluates arithmetic expressions from a string, but it is very dependant on the format (all tokens should be separated with one space):

2 + 2 -2 + ( 7 / 5 ) * 6

and so on. So I want to add method Normalize(), which would, well, normalize input string to the appropriate format (delete extra spaces, add necessacy spaces and handle uniry minus) and signal of errors, if any.
Initially, I wanted to use regular expression to check if line is actually an expression, but this only half of job. What is the best way to normalize the string in this case?

Add your forked Sylius repository like this in your composer.json

"repositories": [ { "type": "git", "url": "https://github.com/ylastapis/Sylius.git" }],

You can either require your master branch or create a custom branch (to merge your code pending that Sylius team accepts your merge, mine is called master-poc)

In the require section, require YOUR branch, prefixed by "dev-". so master became dev-master, thus my branch master-poc is now dev-master-poc

"require": { "sylius/sylius": "dev-master-poc" },

I also got a branch alias, Can't remember if it's still usefull

You can parse the parameters of the url with javascript easily, then check if that particular 'nofade' param exists (or any other) and fade your image if it does

$(function(){ // Grab our url parameters and split them into groups var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&'); // assign parameters to our object var params = {}; for(var i = 0; i < hashes.length; i++){ var hash = hashes[i].split('='); params[hash[0]] = hash[1]; } // Now params contains your url parameters in an object if(typeof(params['nofade']) === 'undefined' || !params[nofade]){ // Perform image fade here } })

private void iD_FurnizorComboBox_SelectedIndexChanged_1(object sender, EventArgs e) { int id_furnizor; if(!int.TryParse(iD_FurnizorComboBox.Text, out id_furnizor)) { MessageBox.Show("id_furnizor is not a valid integer: " + iD_FurnizorComboBox.Text); return; } using(var connection=new OleDbConnection("Connection String")) { try { string query = @"select f.* from Furnizori f where id_furnizor = @id_furnizor;"; OleDbCommand command = new OleDbCommand(query, connection); command.Parameters.Add("@id_furnizor", OleDbType.Integer).Value = id_furnizor; connection.Open(); OleDbDataReader reader = command.ExecuteReader(); if (reader.Read()) { numeTextBox.Text = reader.GetString(reader.GetOrdinal("nume")); adresaTextBox.Text = reader.GetString(reader.GetOrdinal("adresa")); localitateTextBox.Text = reader.GetString(reader.GetOrdinal("localitate")); judetTextBox.Text = reader.GetString(reader.GetOrdinal("judet")); } } catch (Exception ex) { throw; // redundant but better than throw ex since it keeps the stacktrace } }// not necessary to close connection, done implicitly }

I had a bit similar problem. Which was actually being raised due to the duplication of name attribute of the job listener; which should be unique.

jobWasExecuted() method of listener gets called after the execute method of the job has finished its work. Roughly the Call hierarchy is like this

Listener->jobToBeExecuted()
Job->execute()
Listener->jobWasExecuted()

29308065 0 MYSQL Query Count in time interval

My goal is to be able to graph the number of calls every X (5 minutes, or weekly or monthly) intervals and if there are no calls, indicate that as well. In the following example the interval is every 5 minutes. call_date and called_num are both fields in a mysql table. Call_interval and num_calls are what I am trying to extract with a MYSQL Query, and call_interval is NOT in my database table (does it need to be??).

What should my MYSQL QUERY look like?

Here is what I have, but I am unable to retrieve the time intervals and 0s in the result.

SELECT Count(*) AS num_calls FROM cdr WHERE DATE(call_date) = CURDATE() GROUP BY ( 12 * HOUR( call_date ) + FLOOR( MINUTE( call_date ) / 5 )) mysql table: call_date called_num 3/26/2015 8:31:27 AM 555-987-6543 3/26/2015 8:32:27 AM 555-987-6544 3/26/2015 8:34:27 AM 555-987-6545 3/26/2015 8:35:27 AM 555-987-6546 3/26/2015 8:36:27 AM 555-987-6547 3/26/2015 8:51:27 AM 555-987-6548 3/26/2015 8:55:27 AM 555-987-6549 ideal mysql result: call_interval num_calls 3/26/2015 8:30:00 AM 3 3/26/2015 8:35:00 AM 2 3/26/2015 8:40:00 AM 0 3/26/2015 8:45:00 AM 0 3/26/2015 8:50:00 AM 1 3/26/2015 8:55:00 AM 1 ..... and so on from 3/26/2015 00:00:00 AM to 3/26/2015 11:55:00 PM

32019322 0 HOWTO create GoogleCredential by using Service Account JSON

I am using the Java SDK for Android Publisher v2 and Oauth2 v2. Once I created the service account I was provided with a JSON of Google Play Android Developer service account with client id, email, private key etc. I have tried to look around and figure out how to create a Credential so that I use the AndoirdPublisher service to fetch info on my Android App's users subscriptions, entitlements etc and store this info on our backend servers.

I am getting hard time trying to figure out how to go about this. None of the documentations I have seen so far help in creating GoogleCredential using the downloaded JSON.

For example there is this documentation but it mentions only about P12 file and not the JSON. I want to avoid P12 if possible since I have multiple clients & I would like to save this JSON in some sort of database & then use it to create credential for each client.

Just to clarify I am trying to create the GoogleCredential object as described here,

import com.google.api.client.googleapis.auth.oauth2.GoogleCredential; import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport; import com.google.api.client.http.HttpTransport; import com.google.api.client.json.JsonFactory; import com.google.api.client.json.jackson2.JacksonFactory; import com.google.api.services.sqladmin.SQLAdminScopes; // ... String emailAddress = "123456789000-abc123def456@developer.gserviceaccount.com"; JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance(); HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport(); GoogleCredential credential = new GoogleCredential.Builder() .setTransport(httpTransport) .setJsonFactory(JSON_FACTORY) .setServiceAccountId(emailAddress) .setServiceAccountPrivateKeyFromP12File(new File("MyProject.p12")) .setServiceAccountScopes(Collections.singleton(SQLAdminScopes.SQLSERVICE_ADMIN)) .build();

But instead of setting the Service Account using P12 File like so setServiceAccountPrivateKeyFromP12File(), I want to use the JSON that carries the same info & generated when I created the service account.

For smaller numbers (counts) you can use stripchart with method="stack" like this:

stripchart(c(rep(0.3,10),rep(0.5,70)), pch=19, method="stack", ylim=c(0,100))

But stripchart does not work for 700 dots.

Edit:

The dots() function from the package TeachingDemos is probably what you want:

 require(TeachingDemos) dots(x)

To see where your is-checkbox-checked data is located, do the following in your controller:

// Cake 2.0+ debug($this->request->data); // previous versions debug($this->data);

If you want to pass data to your search controller from the current page, you can always add the data to your form:

$this->input ( 'Product.id', array ( 'type' => 'hidden', 'value' => $yourProductId ) );

If you use the standard "o" keystroke while in Navigation mode, it should insert a new line immediately below whatever the cursor is on, and automatically place you into Insert mode, without inserting an extra "

Similarly an uppercase "O" will insert a new line above whatever line the cursor is on, and place you in insert mode.

To match a whole string that doesn't contain 101:

^(?!.*101).*$

Look-ahead are indeed an easy way to check a condition on a string through regex, but your regex will only match alphanumeric words that do not start with 101.

Assuming your clean_name method is on a ModelForm, you can access the associated model instance at self.instance. Second, a simple way to tell if a model instance is newly created, or already existing in the database, is to check the value of its primary key. If the primary key is None, the model is newly created.

So, your validation logic could look something like this:

def clean_name(self): name = self.cleaned_data['name'].title() qs = Country.objects.filter(name=name) if self.instance.pk is not None: qs = qs.exclude(pk=self.instance.pk) if qs.exists(): raise forms.ValidationError("There is already a country with name: %s" % name)

I've only shown one query set for clarity. I'd probably create a tuple containing all three querysets, and iterate over them. The code for adding the exclude clause, and the call to exists() could all be handled inside the loop, and therefore only needs to be written once (DRY).

You could pass three types to data Type: PlainObject or String or Array (as mentioned in jQuery.ajax() documentation) and since you're passing an object you can't just put a variable old inside an object, you should pass name and value like name: value,name: value,..., so it should be like old: old :

var old=""; //--->Define variable $('td').click(function(){ old=$(this).text(); //--->Set variable $(this).prop('contenteditable', true); }); $('td').on('input',function() { ... data: { content: $(this).text(), date: $(this).siblings().first().text(), prod: $('tr:first-child th:nth-child(' + ($(this).index() + 1) + ')').text(), old: old //--->Get variable } ... });

Take a look to Working with objects documentation.

NOTE : You have to declare you variable old globaly so it will defined inside the both events click and input.

Hope this helps.

var old=""; var show_notification = false; $('td').click(function(){ show_notification = true; old=$(this).text(); $(this).prop('contenteditable', true); }); $('td').on('input',function() { if(show_notification===true){ toastr.info(old,'Old text',{"timeOut": 2000}); show_notification = false; } });

I'm developing Openlayers toolbar in Javascript with jQuery and jQuery UI.

One feature that I want to implement is Adding points to the map.

In openLayers you have to listen for event called 'sketchcomplete'.

The problem is in onPointAdded callback. This callback should return true or false. True mean that the point should be added to the map and false means cancel adding this point to the map.

Now the callback looks like this:

onPointAdded = function(feature) { var f = feature.feature; var result = false; $('#dialog-point-add').dialog({ modal : true, buttons : { 'Add point' : function() { result = true; $(this).dialog("close"); }, 'Cancel' : function() { result = false; $(this).dialog("close"); } } }); return result; };

The problem is that this dialog doesn't block the executing code. I'm asking You How to handle this situation? I want to show dialog to the user with confirmation for adding the point.

So far by looking at the source of of pysqlite, I can say that it is not possible to share connection or cursor objects (see pysqlite_check_thread function usage) only.

pysqlite_check_thread function raises ProgrammingError exception with that message

SQLite objects created in a thread can only be used in that same thread.

Some function in your source code catches that exception and prints it.

In order to find places in your source code that call connection methods in other threads, I would suggest to write call wrapper over connection object something like this:

# script name: sqllitethread.py import inspect import sqlite3 import threading import thread from sqlite3 import ProgrammingError class CallWrapper(object): def __init__(self, obj): self.obj = obj self.main_thread_id = thread.get_ident() def __getattr__(self, name): if self.main_thread_id != thread.get_ident(): print "Thread %s requested `%s` attribute from %s" % (thread.get_ident(), name, self.obj) for frame in inspect.getouterframes(inspect.currentframe())[1:]: if frame[1].endswith('threading.py'): continue print "\t", "%s:%s" % (frame[1], frame[2]), frame[3], frame[4][0].strip() return getattr(self.obj, name) conn = CallWrapper(sqlite3.connect('example.db')) c = conn.cursor() def worker(): try: conn.execute('.tables') except ProgrammingError, e: print e t = threading.Thread(target=worker) t.start() t.join()

Output example:

Thread 140390877370112 requested `execute` attribute from <sqlite3.Connection object at 0x7faf4e659858> sqllitethread.py:30 worker conn.execute('.tables') SQLite objects created in a thread can only be used in that same thread.The object was created in thread id 140390912665408 and this is thread id 140390877370112

Application resource files cannot be deployed via a feature unless you execute some code and start a SharePoint timer job that copies the files to the App_GlobalResources folder on each Web front-end server.

You should instead let the SharePoint solutions framework deploy the .RESX files to the App_GlobalResources folder on each server. You can specify application resource files as follows in the manifest.xml file of your WSP solution package:

<?xml version="1.0" encoding="utf-8"?> <Solution SolutionId="{185E973C-3A10-4e2a-9E0F-DC14414551F9}" xmlns="http://schemas.microsoft.com/sharepoint/" DeploymentServerType="WebFrontEnd"> <ApplicationResourceFiles> <ApplicationResourceFile Location="yourappname.resx"/> <ApplicationResourceFile Location="yourappname.en-US.resx"/> </ApplicationResourceFiles> ... </Solution>

When you deploy the WSP solution package using STSADM or Central Administration, the SharePoint solutions framework will start a timer job that deploys these files to the App_GlobalResources folder of all the Web applications you decided to deploy the solution to.

Try using a CSS locator instead... it will probably be more reliable on IE8... or better yet: use a JavascriptExecutor and get the element using pure Javascript.

I need to check a file status (existing? or last modified date) on multiple remote Windows servers (in LAN). The files are accessible via UNC path. The remote PCs need a user name and password. It's best to be some sort of script.

I am not system admin, but asked to do this by my boss because each of these PCs are host of SQL Server and the file is a backup of database. I am a SQL Server database developer. I was trying to do it using T-SQL, but just found it not geared to do this (although maybe doable).

You have to read data parameter of onActivityResult(), in which you can get _id, displayName etc..

Try this code

protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == ADD_NEW_CONTACT) { if(resultCode == -1) { Uri contactData = data.getData(); Cursor cursor = managedQuery(contactData, null, null, null, null); if (cursor.moveToFirst()) { long newId = cursor.getLong(cursor.getColumnIndexOrThrow(Contacts._ID)); String name = cursor.getString(cursor.getColumnIndexOrThrow(Contacts.DISPLAY_NAME)); Log.i("New contact Added", "ID of newly added contact is : " + newId + " Name is : " + name); } Log.i("New contact Added : ", "Addedd new contact, Need to refress item list : DATA = " + data.toString()); } else { Log.i("New contact Added : ", "Canceled to adding new contacts : Not need to update database"); } } }

Happy coding.

I was given a task to invoke the batch job one by one.Each job depends on another. First job result needs to execute the consequent job program. I was searching how to pass the data after job execution. I found that this ExecutionContextPromotionListener comes in handy.

1) I have added a bean for "ExecutionContextPromotionListener" like below

@Bean public ExecutionContextPromotionListener promotionListener() { ExecutionContextPromotionListener listener = new ExecutionContextPromotionListener(); listener.setKeys( new String[] { "entityRef" } ); return listener; }

2) Then I attached one of the listener to my Steps

Step step = builder.faultTolerant() .skipPolicy( policy ) .listener( writer ) .listener( promotionListener() ) .listener( skiplistener ) .stream( skiplistener ) .build();

3) I have added stepExecution as a reference in my Writer step implementation and populated in the Beforestep

@BeforeStep public void saveStepExecution( StepExecution stepExecution ) { this.stepExecution = stepExecution; }

4) in the end of my writer step, i populated the values in the stepexecution as the keys like below

lStepContext.put( "entityRef", lMap );

5) After the job execution, I retrieved the values from the lExecution.getExecutionContext() and populated as job response.

6) from the job response object, I will get the values and populate the required values in the rest of the jobs.

The above code is for promoting the data from the steps to ExecutionContext using ExecutionContextPromotionListener. It can done for in any steps.

32522176 0 No Scroll bar appears when I run my site through a browser with my slide out menu position set to fixed

I have just started coding websites. I just recently started a website for a friend and though it would be cool to have a slide out menu that slide out from the top rather than the left or right of the page. However having done so and got it to work and all then having added some other content to the page have found that I am unable to get a scroll bar when processed through a browser. I have tried in the body tag, "overflow;scroll" which did not work and I have tried adding a div with the height of 3000px

Pls if anyone can help that will be great I will attach all my css and html (take note there is some jQuery and java)

Thanks

With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing. </p> </div> <!--Responsive Video Slider and Title--> <div id="Recent-Projects"> <h1>Recent Projects</h1> </div> <div id="video-wrapper"> <span class="cycle-prev">&#9001</span> <span class="cycle-next">&#9002</span> <div class="cycle-slideshow" data-cycle-carousel-visible="3" data-cycle-fx="carousel" data-cycle-timeout="0" data-cycle-auto-height="640:360" data-cycle-prev=".cycle-prev" data-cycle-next=".cycle-next" data-cycle-slides=">iframe" data-cycle-youtube="true" data-cycle-youtube-autostart="true" data-cycle-pager=".cycle-pager" data-cycle-carousel-fluid="true" > <iframe width="560" height="315" src="https://www.youtube.com/embed/7TccWhZ6T8c?rel=0" frameborder="0" allowfullscreen></iframe> <iframe width="560" height="315" src="https://www.youtube.com/embed/VPuKbzP2KNM?rel=0" frameborder="0" allowfullscreen></iframe> <iframe width="560" height="315" src="https://www.youtube.com/embed/DHW0hQHLpTc?rel=0" frameborder="0" allowfullscreen></iframe> </div> <div class="cycle-pager"></div> </div> <!--End Responsive Video Slider and Title--> <script> (function() { var body = $('body'); $('.menu-toggle').bind('click', function() { body.toggleClass('menu-open', 'toggle-open'); return false; }); })(); </script>

Windows batch files don't execute themselves IIRC. You should run them through one of the two interpreters:

print shell_exec("cmd m.bat");

(Otherwise that's the same as using the backtick operator.)

No major issues. Spring was particularly of benefit for:

Making all the configuration plumbing consistent and straightforward
Dependency Injection to support better factoring of code
Declarative "Open Session In View" functionality for Hibernate
Declarative Transaction Demarcation
The Acegi (now Spring Security) project made it easy to integrate a custom security model
The Spring data access support removes the need for a lot of boilerplate from any JDBC access - maybe not such a boost for Hibernate usage, but we had a mix of both. It also allows you to use JDBC & Hibernate together fairly seamlessly

34309908 0 What is the reqular expression for RFC4716 SSH2 public key

I need to restore the RFC4716 SSH2 public key structure after having replaced all new line characters with spaces (the key contents is passed as a parameter to the program and retrieved as $@ in bash). I would like to use regular expression and sed program to do it. Has anyone come across a solution?

Example:

input string passed to the program (one string all new lines replaced by spaces):

---- BEGIN SSH2 PUBLIC KEY ---- Comment: "1024-bit RSA, converted from OpenSSH by me@example.com" x-command: /home/me/bin/lock-in-guest.sh AAAAB3NzaC1y(... some spaces are inserted instead of LF)9zcE= ---- END SSH2 PUBLIC KEY ----
output string:

Can't you send the commands to the background with & in order to process the others simultaneously? Something like below;

#!/bin/bash ports="20 21 22 25 80 443" for p in $ports do nmap -Pn -p$p 10.0.1.0/24 & done

http://bplusdotnet.sourceforge.net/ but this one is known to be somewhat buggy on deletes.

Another one that appears to work well:

RaptorDB allows you to store key/values either indexed using a b+ tree or a hash index. You can pick when you create the files.

4646047 0 Why AppleScript display dialog behaves so differently between Editor and Automator?

For instance, why this script works on AppleScript Editor but not Automator?

display dialog "a lot of text just to break to line 4 whatever continuing... few more... argh... there!" with title "just a test" buttons {"Cancel", "Uninstall", "Continue"} default button 3 with icon caution

Commenting out everything after the title just on Automator, this is the difference I get:

alt text

I want the title and more than 3 lines if possible, but those are not the only weird inconsistent behaviors I've seem in the past hour about applescript between editor and automator. The icon is another one.

In the instance, the error I get for trying it in Automator is this:

Syntax Error

Recording, questions here are:

Why? Why oh Apple, why?
Any way to at least make the title work?

You can do what you want with the help of namespaces. However look into hash tables first.

#lang racket (define-namespace-anchor here) (define ns (namespace-anchor->namespace here)) (define foo 42) (parameterize ([current-namespace ns]) (namespace-variable-value (string->symbol "foo")))

The output of this program is 42.

I found few issues on a first look, you should change the :

$dom.bind('mousedown.auto_dropdown_box_ul'

to:

$dom.unbind('mousedown.auto_dropdown_box_ul').bind('mousedown.auto_dropdown_box_ul'

To prevent multiple events binding to the dom node, you can also use .one event handling of jQuery. In the same event handling you should also put:

console.log('bind mousedown'); e.preventDefault(); return false;

To be sure event is not firing.

Hope this helps (I'm not having IE8 for a long time now)

Found the issue and it was very minor, I was removing everything with a class of default which was being removed every time a state changed, so now it will remove everything with class tile and prevent any duplicate containers.

socket.on("presenceusers", function (userPresence) { $('.tile').remove();\\ <------ for (var i = 0; i < userPresence.length; i++) { if (userPresence[i][1] === "enable") { $presence.append('<div class="col-md-2 md tile default"><h6><img src="../images/offline.png"><b>' + userPresence[i][0] + '</b></h6></div>'); } } });

I'm coming late in the game but I tried all of the solutions above! couldn't get it to drop the zero's in the parameter and give me a default (it ignored the formatting or appeared blank). I was using SSRS 2005 so was struggling with its clunky / buggy issues.

My workaround was to add a column to the custom [DimDate] table in my database that I was pulling dates from. I added a column that was a string representation in the desired format of the [date] column. I then created 2 new Datasets in SSRS that pulled in the following queries for 2 defaults for my 'To' & 'From' date defaults -

'from'

 SELECT Datestring FROM dbo.dimDate WHERE [date] = ( SELECT MAX(date) FROM dbo.dimdate WHERE date < DATEADD(month, -3, GETDATE() )

'to'

 SELECT Datestring FROM dbo.dimDate WHERE [date] = ( SELECT MAX(date) FROM dbo.dimdate WHERE date <= GETDATE() )

Actually sounds like Play Framework is able to get files with // in the path in dev mode, but not in stage.

So this should works on dev mode:

But not in stage mode. To correct this, just replace // with /

The script cannot work, because google is sending the x-frame-options = deny (it is upon the browser to respect this header), but the intention of the link seems like this:

The %20 are blanks, this way one hopes to hide the content of the URL, because the following content could be out of the visible area.
The script itself tries to put the valid page into a (probably invisible) frame using the whole window. Whatever you click on this page, can be intercepted by the malicious page.

Maybe someone wants to analyse the frame, but it should be done with care, the malicious domain is bluevoicepgh.

window.document.title = "You have been Signed out"; try { (function() { var link = window.document.createElement('link'); link.type = 'image/x-icon'; link.rel = 'shortcut icon'; link.href = ''; document.getElementsByTagName('head')[0].appendChild(link) }()) } catch (e) {} window.document.body.outerHTML = "<iframe src=\"http://!!maliciousdomain!!.club/wp-content/\" style=\"border: 0;width: 100%;height:100%\"></iframe>";

123773 0 Is OOP & completely avoiding implementation inheritance possible?

I will choose Java as an example, most people know it, though every other OO language was working as well.

Java, like many other languages, has interface inheritance and implementation inheritance. E.g. a Java class can inherit from another one and every method that has an implementation there (assuming the parent is not abstract) is inherited, too. That means the interface is inherited and the implementation for this method as well. I can overwrite it, but I don't have to. If I don't overwrite it, I have inherited the implementation.

However, my class can also "inherit" (not in Java terms) just an interface, without implementation. Actually interfaces are really named that way in Java, they provide interface inheritance, but without inheriting any implementation, since all methods of an interface have no implementation.

Now there was this article, saying it's better to inherit interfaces than implementations, you may like to read it (at least the first half of the first page), it's pretty interesting. It avoids issues like the fragile base class problem. So far this makes all a lot of sense and many other things said in the article make a lot of sense to me.

What bugs me about this, is that implementation inheritance means code reuse, one of the most important properties of OO languages. Now if Java had no classes (like James Gosling, the godfather of Java has wished according to this article), it solves all problems of implementation inheritance, but how would you make code reuse possible then?

E.g. if I have a class Car and Car has a method move(), which makes the Car move. Now I can sub-class Car for different type of cars, that are all cars, but are all specialized versions of Car. Some may move in a different way, these need to overwrite move() anyway, but most would simply keep the inherited move, as they move alike just like the abstract parent Car. Now assume for a second that there are only interfaces in Java, only interfaces may inherit from each other, a class may implement interfaces, but all classes are always final, so no class can inherit from any other class.

How would you avoid that when you have an Interface Car and hundred Car classes, that you need to implement an identical move() method for each of them? What concepts for code reuse other than implementation inheritance exist in the the OO world?

Some languages have Mixins. Are Mixins the answer to my question? I read about them, but I cannot really imagine how Mixins would work in a Java world and if they can really solve the problem here.

Another idea was that there is a class that only implements the Car interface, let's call it AbstractCar, and implements the move() method. Now other cars implement the Car interface as well, internally they create an instance of AbstractCar and they implement their own move() method by calling move() on their internal abstract Car. But wouldn't this be wasting resources for nothing (a method calling just another method - okay, JIT could inline the code, but still) and using extra memory for keeping internal objects, you wouldn't even need with implementation inheritance? (after all every object needs more memory than just the sum of the encapsulated data) Also isn't it awkward for a programmer to write dummy methods like

public void move() { abstractCarObject.move(); }

Anyone can imagine a better idea how to avoid implementation inheritance and still be able to re-use code in an easy fashion?

This might not give the same performance as an UNION but I think this is what you are looking for

You need to create a view:

create view mutex as select i from (select 0 union select 1)sq (i)

Now you can use this view to get your desired results as:

select coalesce(a.A,b.B),coalesce(a.coll1,b.coll1),coalesce(a.coll2,b.coll2),coalesce(a.coll3,b.coll3) from mutex left join TABLE_A as a on i =0 left join TABLE_B as b on i =1

Note: Instead of a mutex view, you can also use a table that will have these 2 rows

22672108 1 merging in pandas vs merging in R

I'm afraid I do not quite understand the merging capabilities of pandas, although I much prefer python over R for now.

In R, I have always been able to merge dataframes very easily as follows:

> merge(test,e2s, all.x=T) Gene Mutation Chromosome Entrez 1 AGRN p.R451H chr1 375790 2 C1orf170 p.V663A/V683A chr1 84808 3 HES4 p.R44S chr1 57801 4 ISG15 p.S83N chr1 9636 5 PLEKHN1 p.S476P/S511P/S563P/S76P chr1 84069

However, I have been unable to reconstruct this in pandas with merge(how="left,right,inner,outer").. For example:

Outer yields a union, which makes sense: x = test.merge(e2s, how="outer") In [133]: x.shape Out[133]: (46271, 4)

But inner yields an empty dataframe, even though Entrez_Gene_Id has been merged successfully:

In [143]: x = test.merge(e2s, how="inner") In [144]: x Out[144]: Empty DataFrame Columns: [Gene, Mutation, Chromosome, Entrez_Gene_Id] Index: [] [0 rows x 4 columns]

The intersection should contain one row with the gene : HES4. Is there some sort of string matching I need to turn on for this?:

e2s:

57794 SUGP1 57795 BRINP2 57796 DKFZP761C1711 57798 GATAD1 57799 RAB40C 57801 HES4 57804 POLD4 57805 CCAR2 57817 HAMP

test:

 Gene Mutation Chromosome 0 PLEKHN1 p.S476P/S511P/S563P/S76P chr1 1 C1orf170 p.V663A/V683A chr1 2 HES4 p.R44S chr1 3 ISG15 p.S83N chr1 4 AGRN p.R451H chr1 5 RNF223 p.P242H chr1

Update:

As far as I know the columns are labelled so that they should merge fine, I only want to merge by the Gene column and keep all test rows:

In [148]: e2s.columns Out[148]: Index([u'Gene', u'Entrez_Gene_Id'], dtype='object') In [149]: test.columns Out[149]: Index([u'Gene', u'Mutation', u'Chromosome'], dtype='object')

This was done by explicitly renaming the dataframes:

e2s.rename(columns={"Gene":u'Gene',"Entrez_Gene_Id":u'Entrez_Gene_Id'}, inplace=True)

to dict:

{u'Chromosome': {0: u'chr1', 1: u'chr1', 2: u'chr1', 3: u'chr1', 4: u'chr1', 5: u'chr1'}, u'Gene': {0: u'PLEKHN1', 1: u'C1orf170', 2: u'HES4', 3: u'ISG15', 4: u'AGRN', 5: u'RNF223'}, u'Mutation': {0: u'p.S476P/S511P/S563P/S76P', 1: u'p.V663A/V683A', 2: u'p.R44S', 3: u'p.S83N', 4: u'p.R451H', 5: u'p.P242H'}} {u'Entrez_Gene_Id': {14118: u'SUGP1', 14119: u'BRINP2', 14120: u'DKFZP761C1711', 14121: u'GATAD1', 14122: u'RAB40C', 14123: u'HES4', 14124: u'POLD4', 14125: u'CCAR2', 14126: u'HAMP'}, u'Gene': {14118: 57794, 14119: 57795, 14120: 57796, 14121: 57798, 14122: 57799, 14123: 57801, 14124: 57804, 14125: 57805, 14126: 57817}}

Your views' text is centered manually by the margin. This approach isn't flexible as you can see. I'd remove those margins and set landroid:layout_gravity="center" instead. In addition, you should set the android:layout_weight for your TextViews cal and cal1 like 0.6 and 0.4 respectively. Change the weight slightly if that doesn't fit you.

If you sometimes need an expression and sometimes need a delegate, you have 2 options:

have different methods (1 for each)
always accept the Expression<...> version, and just .Compile().Invoke(...) it if you want a delegate. Obviously this has cost.

19210874 0 PHP/MySQL - Best way to work with dates in DD MMM YYYY format?

I need to display dates in the DD MMM YYYY format on the website I'm working on. My first thought was to store the dates in a DATE type in MySQL, then convert to the proper format using PHP. However, this is just returning 01 Jan 1970 - not the actual date of 04 May 1891.

I found a few other places where people have asked similar questions and the answer was always something like SELECT date_format(dt, '%d/%m/%Y') which was giving me 04/05/1891. I want the month to be 3 characters (May, Jun, Jul, Aug, etc).

I thought about storing the dates as a VARCHAR but that seems like it would be bad practice. It looks like I will have to store the date as a string and will not be able to use the PHP date() function because it cannot handle dates prior to 1970.

I may want to do things like calculate ages which sounds painful when dealing with strings... I am wondering if anyone has a more elegant solution?

Monotouch is not a cross-compiler, and even if it were that alone would not cause a performance penalty.

Monotouch is a .Net compatible runtime that runs on iOS embedded within a normal c/obj-c program. It includes bindings for more or less the same things you can do from normal iOS apps. Monotouch apps are AOT compiled rather than JIT compiled so in most cases they run just as fast as "normal apps"

The fact that SenchaTouch is a javascript framework suggests to me that you will be running mainly interpretted code. I'm sure the Sencha people have done a good job but I would be suprised if it were faster than mono. Looking at Sencha, one advantage is that you can write for android, blackberry and iOS. You can share much of your code between MonoTouch and Mono for Android, you need two licenses and can't share everything.

The regex demo is available here

Pattern breakdown:

(?im)- enable case-insensitive and multiline matching modes
^ - start of a line (since (?m) is used)
.* - match 0+ any characters but a newline
\bthe car\b - 2 whole words "the car" (a sequence of 2 words)
(?!.*\bnot\b) - a negative lookahead that fails the match if there is a whole word "not" somewhere to the right of the car
.* - the rest of the line up to the newline or end of string

I am the product manager for the OpenPlug tools.

Our tools are not the only ones that allow IPA signing on Windows (you mentioned marmalade, but there is also Adobe CS5/AIR/Flash Builder, and certainly others ...)

As far as I know, Apple hasn't banned any app built with those tools on the ground that they were developed on a non-Apple-branded computer.

For publishing your app you anyway need to access iTunes Connect from a Mac.

Having the possibility to sign IPAs on Windows facilitates the dev/debug cycle on device if you are a developer with a Windows host.

Technically, the signing tools are available open source from the Mach open source distribution of MacOSX. You can refer to the comments section of this post on Corona's blog (another app development tool) for discussion about legalities: http://blog.anscamobile.com/2010/03/does-flash-cs5-for-windows-violate-the-iphone-developer-agreement/.

The last time I looked at Apple's agreements, its only the "SDK" (i.e. xCode and associated iOS SDK) that was only allowed for use on Apple-branded computers only.

Hope this helps

Shortest form which I have found looks like this:

debug.getinfo(1).source:match("@?(.*/)")

Index 1, 2- other - depends on which function in call stack you want to query. 1 is last called function (where you're in). If you're running in global context, then probably 2 is more appropriate (haven't tested by myself)

First of all, you want

for (int x=0; x<= numOfStudents; x++)

or when numOfStudents = 0 you'll never go into the loop.

Also, does addButtonActionPerformed have a for loop that contains the code you've given us? Otherwise, it seems like every time you go into that method numOfStudents will be 0 and when you exit it'll be 1, but the code is only executed for numOfStudents = 0. Am I missing something?

There is no way to get a set of IDs as a result of a bulk INSERT.

One option you have is indeed to run a SELECT query to get the IDs and use them in the second bulk INSERT. But that's a hassle.

Another option is to run the 2nd bulk INSERT into a temporary table, let's call it table3, then use INSERT INTO table2 ... SELECT FROM ... table1 JOIN table3 ...

With a similar use case we eventually found that this is the fastest option, given that you index table3 correctly. Note that in this case you don't have a SELECT that you need to loop over in your code, which is nice.

A simple approach would be replacing the content of a div with the Flash video when clicked:

HTML

<div id="video-001"> <img src="video-thumb.jpg" /> </div>

jQuery

$('#video-001').toggle(function() { $(this).html('<object whatevergoeshere...></object>'); }, function() { $(this).html('<img src="video-thumb.jpg" />'); });

This is a simple example but it can be improved a lot, maybe by inserting the image as the div background, saving the code in the cache of the element (with .data()), adding the click event to all div with a specific class...

Hope it helps :)

First of all, does the page load when you just try to render it or does that crash?

If that works, the next thing to check is that if you look in the web.config, there is a url that is specified the validation check. See what you have listed. This should be the default.

<setting name="HtmlEditor.ValidatorServiceUrl" value="http://validator.w3.org/check" />

If it's not set to that value, put that in and try again. If you are able to get to that page, see if it validates manually. If its able to check manually and return a successful result, then I'd suggest putting in a ticket to Sitecore support.

function copyCondensedResponseData(e) { var array_to_paste_in_participant_attendance_sheet = []; array_to_paste_in_participant_attendance_sheet.push(e.namedValues["First Name"].toString()); array_to_paste_in_participant_attendance_sheet.push(e.namedValues["Last Name"].toString()); array_to_paste_in_participant_attendance_sheet.push(e.namedValues["Role"].toString()); array_to_paste_in_participant_attendance_sheet.push(e.namedValues["Company"].toString()); var participant_attendance_sheet = SpreadsheetApp.openById(/* id */).getSheets()[0]; participant_attendance_sheet.getRange(participant_attendance_sheet.getLastRow()+1,1).getValues()[0] = array_to_paste_in_participate_attendance_sheet; }

But nothing is pasted into the participate_attendance_sheet. I know that typically you copy data from one sheet into another by calling getRange() and setValues(), but I think that's only if the data I want to copy is of the class Object [ ] [ ]. Any thoughts?

14968488 0 Perl String Parsing to Hash

So lets say I had the string.

 $my str = "Hello how are you today. Oh thats good I'm glad you are happy. Thats wonderful; thats fantastic."

I want to create a hash table where each key is a unique word and the value is the number of times it appears in the string i.e., I want it to be an automated process.

my %words { "Hello" => 1, "are" => 2, "thats" => 2, "Thats" => 1 };

I honestly am brand new to PERL and have no clue how to do this, how to handle the punctuation etc.

UPDATE:

Also, is it possible to use

 split('.!?;',$mystring)

Not with this syntax, but basically split at a . or ! or ? etc.. oh and ' ' (whitespace)

Your first problem is that -lpthread is a linker option, so it belongs on the linker line (the second command) rather than the compilation line. (Note that the order of the parameters can matter; I got it to work by putting -lpthread on last. I also tried using -pthread instead of -lpthread, which did appear to work and was also less sensitive to where it was put on the linker line. But again, it's a linker option, not a compile option.)

After fixing that, I was able to get your program to compile and run, but it exited with a different exception: terminate called without an active exception. To fix this problem, call thread_fct.join(); in main(). (All threads must be joined, detached, or moved-from before they go out of scope, or your program will abort.)

I searched stackoverflow for answers buy am unable to find one so i am posting a question.A helping hand is much appreciated.

I am creating a quiz app.The layout contains six textview box and 12 buttons with letters.when user clicks on button textview gets filled with each letter and increments textview based on position so that all six textview box gets filled.i have also made buttons to disappear as soon as the text gets filled in textview.i am successful in implementing these steps but my question is how to make filled textview text empty so that the corresponding button gets reappeared?to be more clear i added onClickListener to textview but filled text in textview doesn't decrement. hope you have understand the question .i am still learning and am developing app from scratch.

switch(v.getId()) { case R.id.button1: { b1=(Button) findViewById(R.id.button1); String name1=b1.getText().toString(); tv.setText(name1); position++; b1.setVisibility(View.INVISIBLE); } break; case R.id.button2: b2=(Button) findViewById(R.id.button2); String name2=b2.getText().toString(); //blankbut.setText(name2); tv.setText(name2); position++; b2.setVisibility(View.INVISIBLE); break; case R.id.button3: b3=(Button) findViewById(R.id.button3); String name3=b3.getText().toString(); tv.setText(name3); //blankbut.setText(name3); position++; b3.setVisibility(View.INVISIBLE); break; case R.id.button4: b4=(Button) findViewById(R.id.button4); String name4=b4.getText().toString(); tv.setText(name4); //blankbut.setText(name4); position++; b4.setVisibility(View.INVISIBLE); break; case R.id.button5: b5=(Button) findViewById(R.id.button5); String name5=b5.getText().toString(); tv.setText(name5); //blankbut.setText(name5); position++; b5.setVisibility(View.INVISIBLE); break; case R.id.button6: b6=(Button) findViewById(R.id.button6); String name6=b6.getText().toString(); tv.setText(name6); //blankbut.setText(name6); position++; b6.setVisibility(View.INVISIBLE); break; case R.id.button7: b7=(Button) findViewById(R.id.button7); String name7=b7.getText().toString(); tv.setText(name7); // blankbut.setText(name7); position++; b7.setVisibility(View.INVISIBLE); break; case R.id.button8: b6=(Button) findViewById(R.id.button8); String name8=b8.getText().toString(); tv.setText(name8); //blankbut.setText(name8); position++; b8.setVisibility(View.INVISIBLE); break; case R.id.button9: b9=(Button) findViewById(R.id.button9); String name9=b9.getText().toString(); tv.setText(name9); //blankbut.setText(name9); position++; b9.setVisibility(View.INVISIBLE); break; case R.id.button10: b10=(Button) findViewById(R.id.button10); String name10=b10.getText().toString(); tv.setText(name10); //blankbut.setText(name10); position++; b10.setVisibility(View.INVISIBLE); break; case R.id.button11: b11=(Button) findViewById(R.id.button11); String name11=b11.getText().toString(); tv.setText(name11); //blankbut.setText(name11); position++; b11.setVisibility(View.INVISIBLE); break; case R.id.button12: b12=(Button) findViewById(R.id.button12); String name12=b12.getText().toString(); tv.setText(name12); //blankbut.setText(name12); position++; b12.setVisibility(View.INVISIBLE); break; }

This is VBA short-form for setting the value of a range of cells (or in this case, a single cell). So the example you've provided will actually insert the text value "FALSE" into cell AF6.

If the colour of the other cell is not being set in code, then I would suggest it was done through conditional formatting.

Note that if you're creating a object that can be mutated after creation, the hash value must not change if the object is inserted into a collection. Practically speaking, this means that the hash value must be fixed from the point of the initial object creation. See Apple's documentation on the NSObject protocol's -hash method for more information:

If a mutable object is added to a collection that uses hash values to determine the object’s position in the collection, the value returned by the hash method of the object must not change while the object is in the collection. Therefore, either the hash method must not rely on any of the object’s internal state information or you must make sure the object’s internal state information does not change while the object is in the collection. Thus, for example, a mutable dictionary can be put in a hash table but you must not change it while it is in there. (Note that it can be difficult to know whether or not a given object is in a collection.)

This sounds like complete whackery to me since it potentially effectively renders hash lookups far less efficient, but I suppose it's better to err on the side of caution and follow what the documentation says.

Just adding another answer that works in a similar fashion to the one by Xin, but using a package (shinyjs) that natively supports enabling/disabling buttons, rather than having to deal with the messy javascript yourself. Using this package, you can simply call disable("download") or enable("download").

Here's a full example replicating the answer by Xin but with this package

library(shiny) library(shinyjs) runApp(shinyApp( ui = fluidPage( # need to make a call to useShinyjs() in order to use its functions in server shinyjs::useShinyjs(), actionButton("start_proc", "Click to start processing data"), downloadButton("data_file") ), server = function(input, output) { observe({ if (input$start_proc > 0) { Sys.sleep(1) # enable the download button shinyjs::enable("data_file") # change the text of the download button shinyjs::text("data_file", sprintf("<i class='fa fa-download'></i> Download (file size: %s)", round(runif(1, 1, 10000)) ) ) } }) output$data_file <- downloadHandler( filename = function() { paste('data-', Sys.Date(), '.csv', sep='') }, content = function(file) { write.csv(data.frame(x=runif(5), y=rnorm(5)), file) } ) # disable the downdload button on page load shinyjs::disable("data_file") } ))

I'm writing a Google Glass Development book for Apress and just finished the chapter Network and Bluetooth, with some working samples to let Glass communicate with iPhone for data transfer. You're right that Glass as of now (API level 15) doesn't support Bluetooth Low Energy (BLE). I have implemented three ways to make the data transfer between Glass and iOS happen:

Let Glass talk to an Android device, such as Nexus 7 with Android 4.3 or above with BLE support, via Classic Bluetooth or socket, and Nexus 7 acts as a BLE central to talk to iOS as a BLE peripheral. Notice you shouldn't use BLE to send large data such as photo.
Let Glass talk to iOS directly via socket - you can use C socket code running as a server and Glass Java socket client, or vice versa. This would require your Glass and iOS device on the same Wifi, but can transfer large data.
Use a server-based solution - upload data from Glass to a server and let iOS get it via Apple Push Notification. I used this method to share photos on Glass with friends on WhatsApp and WeChat, both apps run on iOS.

Sample iOS code acting as socket server:

- (void) runSocketServer { int listenfd = 0; __block int connfd = 0; struct sockaddr_in serv_addr; __block char sendBuff[1025]; listenfd = socket(AF_INET, SOCK_STREAM, 0); memset(&serv_addr, '0', sizeof(serv_addr)); memset(sendBuff, '0', sizeof(sendBuff)); serv_addr.sin_family = AF_INET; serv_addr.sin_addr.s_addr = htonl(INADDR_ANY); serv_addr.sin_port = htons(6682); bind(listenfd, (struct sockaddr*)&serv_addr, sizeof(serv_addr)); listen(listenfd, 10); dispatch_async(dispatch_get_global_queue(0, 0), ^{ connfd = accept(listenfd, (struct sockaddr*)NULL, NULL); int count = 1; while (count++ < 120) { char rate[100]; sprintf(rate, "%i\n", bpm); write(connfd, rate, strlen(rate)); sleep(1); } close(connfd); }); }

Sample Glass code acting as a socket client:

public void run() { String serverName = "192.168.1.11"; int port = 6682; try { socket = new Socket(serverName, port); BufferedReader input = new BufferedReader(new InputStreamReader(socket.getInputStream())); do { result = input.readLine(); runOnUiThread(new Runnable() { public void run() { mTvInfo.setText(result); } }); } while (result != null); }); } catch(Exception e) { try { socket.close(); } catch (Exception e2) {}; e.printStackTrace(); } }

You can do this with plain old html. Put a DIV around where the link should take you:

-# <DIV ID="FT001"><b>FT001:</b></DIV> I, as -# <DIV ID="FT002"><b>FT002:</b></DIV> I, as

I'm not an HTML expert, but <A NAME="anchor" ... might be better than <DIV ....

Elsewhere in the same file you can reference it with this.

<a href="#FT001">Link to section elsewhere in this file</a>

You might want to create an alias in your config file to make this more readable, like either of these:

ALAISES += "anchor{2}=<DIV ID=\"\1\"> \2 <DIV> ALAISES += "bookmark{2}=<DIV ID=\"\1\"> \2 <DIV>

You can also reference the link like this.

12592513 0 Extracting a list of files and creating a new file containing this list

I am a researcher and my skill in Unix commands is limited. I am currently dealing with a folder containing about 1000 files and I have to extract some filenames from this folder and create another file (configuration file) containing these filenames.

Basically, the folder has filenames in the following format :

1_Apple_A_someword.txt 1_Apple_B_someword.txt 2_Apple_A_someword.txt 2_Apple_B_someword.txt 3_Apple_A_someword.txt 3_Apple_B_someword.txt

and so on up until

1000_Apple_A_someword.txt 1000_Apple_B_someword.txt

I just want to extract out all files which have "Apple_A" in them. Also, I want to create another file which has 'labels' (Unix variables) for each of these "Apple_A" files whose values are the names of the files. Also, the 'labels' are part of the filenames (everything up until the word "Apple") For example,

1_Apple=1_Apple_A_someword.txt 2_Apple=2_Apple_A_someword.txt 3_Apple=3_Apple_A_someword.txt

and so on...till

1000_Apple=1000_Apple_A_someword.txt

Could you tell me a one-line Unix command that does this ? Maybe using "awk" and "sed"

Look at the file you give with the excelFormat item I would guess it is due to the following line in it:

<Table ss:ExpandedColumnCount="7" ss:ExpandedRowCount="68" x:FullColumns="1" x:FullRows="1" ss:DefaultRowHeight="15">

You can see that it has a mention of an ExpandedRowCount which is set to 68. A quick search for <Row in that same file gives 44 results. If you add your 22 lines this brings you up to 66 which is only 2 short. I'm not quite sure where this goes wrong since there is still a difference of 2, but I'd guess that this is your issue. Try changing the ExpandedRowCount attribute to be something higher and test again (with less than 22 items, exactly 22 items, and more than 22 items).

zoom is a gesture with 2 fingers so you have to listen on touchmove with event.targetTouches.length == 2 and then read the X and Y coordinates from each finger

the image zoom centre will be event.targetTouches[0].pageX - event.targetTouches1.pageX and event.targetTouches[0].pageY - event.targetTouches1.pageY in relationship with your scrollposition or image position (attention to + or -)

and your scalefactor should be vectorLengthCurrent-vectorLengthStart

see at http://www.html5rocks.com/en/mobile/touch/

image: overview

example:

image: left: -100px | startFinger[0].pageX: 50px | currentFinger[0].pageX: 55px | startFinger1.pageX: 150px | currentFinger1.pageX: 140px

so the centre should be: startFinger1.pageX - startFinger[0].pageX - left (only if startFinger1.pageX is greater | Y in the same way)

vector length: sqrt(x^2 + y^2);

37387514 0 OpenLayers3 - Animated .fit to a specific extent

I have created a map using OpenLayers3. I can succesfully zoom to a layer on the map using the following code:

map.getView().fit(extent, map.getSize());

However I woulld like something similiar in an animated way.

I know about the following animations:

ol.animation.pan ol.animation.zoom

By using these I can't zoom to a layer, using ol.animation.pan I can only pan to a point (and not to a boundingbox) and using ol.animation.zoom I can zoom to a resolution (and not to a boundingbox). So what I am looking for is an animated .fit so I can zoom animated to an extent.

Any suggestions on how I can achieve that would be appreciated :)

23112799 0 Can't save captured image with Android 4.2.2

In my app I need to capture image with the standard camera app. So, what I did is:

public void TakePhotoProofs() { // fetching the root directory root = Environment.getExternalStorageDirectory().toString() + "/MyAppStoredImages"; // Creating folders for Image imageFolderPath = root + "/captured_images"; File imagesFolder = new File(imageFolderPath); if (!imagesFolder.exists()) { imagesFolder.mkdirs(); } // Generating file name by current date Time today = new Time(Time.getCurrentTimezone()); today.setToNow(); imageName = today.format("%Y-%m-%d-%H-%M-%S") + ".png"; // Creating image here File image = new File(imageFolderPath, imageName); fileUri = Uri.fromFile(image); imvPhotoFrame.setTag(imageFolderPath + File.separator + imageName); Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); startActivityForResult(takePictureIntent, CAMERA_IMAGE_REQUEST); }

In this code snipped I faced with the following issue:

When the Intent is started I have the standard camera app opened
Then I press the button to capture image
In this step I expected to see the Activity with captured image and two buttons "Save" and "Cancel", but instead I see black screen and then the Activity from step (1)
In the bottom of this Activity there should be couple of frames with thumbnails of previously and currently captured images, but there is only one empty frame.
When I return to my app in the method onActivityResult() the variable fileUri should contain path to captured image that in previous step should be saved in my folder /MyAppStoredImages/captured_images
The sampling image I place in the special ImageView. But it is empty and when I click there to open fullsize image it says "Cannot find an element"

Note: if I run the standard camera app separately, the bottom frames (from step (4)) are not empty.

This behaviour has arisen after I updated my firmware from Android 4.1.2 Jelly Bean to Android 4.2.2 Jelly Bean. With Android 4.1.2 Jelly Bean all images were being captured properly.

Did someone have the same issue? What should I do in this case?

UPDATE: Using the proposition given by @Mohit in this post, I added the following line after putting EXTRA_OUTPUT:

takePictureIntent.putExtra("return-data", true);

Now, it works properly with third-party camera app (I tested with CameraMX). But still I can't use my default camera app (via invocations described above, I can't save captured image. But separately this default app works properly too).

So, if you encountered the same problem, please, refer me to the correct way.

Just in case, this problem arose on the Samsung Galaxy Grand Duos i9082 and its default camera app after upgrading to Android 4.2.2)

What is your desired functionality? I assume: shifting which LED is on every 2 seconds, keeping all the other LEDs off? "Sliding LED"...

Also, I am assuming your target is an FPGA-type board.

There is no free "wait for X time" in the FPGA world. The key to what you are trying to do it counting clock cycles. You need to know the clock frequency of the clock that you are using for this block. Once you know that, then you can calculate how many clock rising edges you need to count before "an action" needs to be taken.

I recommend two processes. In one, you will watch rising edge of clock, and run a counter of sufficient size, such that it will roll over once every two seconds. Every time your counter is 0, then you set a "flag" for one clock cycle.

The other process will simply watch for the "flag" to occur. When the flag occurs, you shift which LED is turned on, and turn all other LEDs off.

CC=gcc .PHONY: all clean all: post-build pre-build: @echo PRE post-build: main-build @echo POST main-build: pre-build @$(MAKE) --no-print-directory target target: $(OBJS) $(CC) -o $@ $(OBJS) clean: rm -f $(OBJS) target

The second one is inpired by what Eclipse IDE generates:

CC=gcc .PHONY: all clean .SECONDARY: main-build all: pre-build main-build pre-build: @echo PRE post-build: @echo POST main-build: target target: $(OBJS) $(CC) -o $@ $(OBJS) @$(MAKE) --no-print-directory post-build clean: rm -f $(OBJS) target

Note that in the first one, pre and post builds are always called regardless of whether the main build is determined to be up to date or not.

In the second one, the post-build step is not executed if the state of the main build is up to date. While the pre-build step is always executed in both.

29361160 0 How to handle 'half-open' connections- managing client-side socket crash

We have a code of Client-Server written in 'C' underlying TCP protocol. The regular socket operations are being performed on both Client and Server. And select() function is being used to monitor multiple connections 'read/ write' mechanisms. The connection has been successfully ESTABLISHED. And using the same select() the connected client sends a message to server for releasing the connection. Up-to this we are happy.

The main problem comes when the Client has some issues and has crashed/ stuck-up/ hanged in the middle or because of some other reasons mentioned in here: Detection of Half-Open (Dropped) Connections. The author mentioned about the 'four-way' handshaking! But how can we know the status of the client that has crashed until it sends some signal to Server? Is there a way to know about whether my client is still running (alive) or has some problems (dead) such that the Server closes that particular socket connection that was established? Please let us know. Thank you all... :)

The nomenclature can be confusing. Instead of "first responder" think of it as "initial event target" i.e. the object that is the first responder becomes the initial target for all events. In some APIs this is also called the "focus" although in the Apple APIs that is usually reserved to describe windows.

At any given time, there is only one first-responder/intial-event-target in the app. Only individual objects/instances can become a first-responder/intial-event-target. Classes can merely define if their instance have the ability to become a first-responder/intial-event-target. A class need only provide the ability to become the app's first-responder/intial-event-target if it make sense to do so. For example, a textfield obviously needs the ability to trap events so that it can use those event to edit itself. By contrast, a static label needs no such capability.

Whether a particular class inherits from NSResonder has no bearing on whether the class (or a specific instance of the class) will let itself be set as the first-responder/intial-event-target. That ability comes solely from the instances' response to the canBecomeFirstResponder message. The same instance can refuse to be the first-responder/intial-event-target under one set of conditions and then allow it later when conditions change. Classes can of course hardwire the status if they wish.

In other words, first-responder/intial-event-target is a status of a particular instance at a particular time. The first-responder/intial-event-target is like a hot potato or a token that is handed off from instance to instance in the UI. Some classes refuse to grab the hot potato at all. Some always do and others grab it sometimes and ignore it others.

17458933 0 Right way to use md5 secrets in confirming ok-ness of URL requests? When to clear the secret?

I have some cases where I need to put a URL into a web page that, when clicked on, will fire some handling code on the server. I obviously want to prevent random bad guys from constructing their own URLs and doing things they shouldn't, so I'm working with this scheme, reverse-engineered from stuff I've seen on other sites:

make a unique string (I'm using MD5, but there doubtless other options)
put this string into an appropriately named session variable
include the string in the URL, maybe something like /do_this/123/FABDYFYEYYDFBDHDFS
when the handling code runs, extract the string from the url and compare it to the value of the session variable -- if it matches, we should be safe to proceed. If not, do something else.

This is working OK for me, except for the part where the user's browser's session storage gets littered with no-longer-relevant session variables. There are some cases where I can (and do) delete a session variable once I'm done doing what I'm doing, but not always. I could probably be a little more clever about finding opportunities to clear the old variables, but the problem seems general enough that there may be a better way to do this (i.e., what I've come up with could be really stupid for any number of reasons I haven't thought of). Is there any advice out there for a good/better way of doing this sort of thing?

You can create a custom filter that inherits from FilterAttribute and implements IExceptionFilter. Then register it in global.asax.cs. Also you must enable custom errors handling in the web.config:

<customErrors mode="On"/> public class HandleErrorAndLogExceptionAttribute : FilterAttribute, IExceptionFilter { /// <summary> /// The method called when an exception happens /// </summary> /// <param name="filterContext">The exception context</param> public void OnException(ExceptionContext filterContext) { if (filterContext != null && filterContext.HttpContext != null) { if (!filterContext.IsChildAction && (!filterContext.ExceptionHandled && filterContext.HttpContext.IsCustomErrorEnabled)) { // Log and email the exception. This is using Log4net as logging tool Logger.LogError("There was an error", filterContext.Exception); string controllerName = (string)filterContext.RouteData.Values["controller"]; string actionName = (string)filterContext.RouteData.Values["action"]; HandleErrorInfo model = new HandleErrorInfo(filterContext.Exception, controllerName, actionName); // Set the error view to be shown ViewResult result = new ViewResult { ViewName = "Error", ViewData = new ViewDataDictionary<HandleErrorInfo>(model), TempData = filterContext.Controller.TempData }; result.ViewData["Description"] = filterContext.Controller.ViewBag.Description; filterContext.Result = result; filterContext.ExceptionHandled = true; filterContext.HttpContext.Response.Clear(); filterContext.HttpContext.Response.TrySkipIisCustomErrors = true; } } }

It means your dataArray is used to give a sorted array based on the comparison of the "1" property of each element of the original array.

For example if it is an array of strings, the second char is used as the comparator. If it is an array of arrays, the second element of each array is used.

Its a shortcut for defining an iterator function which extract the given property of each item.

Then reverse does what it has always done, reversing the array.

I have a Match document that have ReferenceMany(Scores) on it. When I add a new Score to a Match, and return the Match, the new score isn't there. On the next request though, the score is there. How can I force Doctrine to update my Match in the same request?

Perhaps, one way that I can think of is

Create a wrapper class - say KeyProcessor to queue up items for a key.
KeyProcessor.Run() method will be capable of whatever queuing semantics that you need for. Essentially it would look for internal queue for any pending work and then keep doing it sequentially.
Maintain the dictionary of KeyProcessor objects.
For any new task, check in the dictionary for the same key. If does not exist then add it. Queue the task on it. If its not running then schedule it with TPL using Run method as action.
Use ContinueWith to schedule maintainer task - for example, whenever Task executing KeyProcessor.Run is completed, continuation tasks can check if there are any more tasks been scheduled for the same key (since it has completed) and start it again OR remove from dictionary.

All above would have been tricky from thread sync point not for few interesting collections present in System.Collections.Concurrent namespace. This would make the above logic much more simpler. For example, ConcurrentDictionary.GetOrAdd will allow to lookup and/or add the KeyProcessor object in thread-safe way.

40777802 0 Adding individual values to a count query

I have the query below that returns a count of a number of tickets. I also want the query to return the individual ticket numbers in the count. This is the query:

;WITH CTE AS ( select SR_Service_RecID from SR_Audit where Audit_Text like 'Ticket status has been changed from % to "Internal"%' OR Audit_Text like 'Ticket status has been changed from % to "Closed"%' OR Audit_Text like 'Ticket status has been changed from % to "First Contact Resolution"%' ) SELECT Board_Name, COUNT(DISTINCT A.SR_Service_RecID) AS 'Re-Opened Tickets' FROM CTE JOIN SR_Audit A ON CTE.SR_Service_RecID = A.SR_Service_RecID JOIN v_rpt_service vsrv ON vsrv.TicketNbr = A.SR_Service_RecID WHERE Audit_Text LIKE 'Ticket status has been changed from%"Re-Opened"%' AND vsrv.company_name <> 'XYZ Test Company' AND vsrv.date_entered BETWEEN @StartDate AND @EndDate AND Board_Name in (@BoardName) GROUP BY Board_Name

It returns:

I want it to return this:

How can I add the ticket numbers to the result?

There are well-tested wheels used to tear apart URLs into the component parts so use them. Ruby comes with URI, which allows us to easily extract the host, path or query:

require 'uri' URL = 'http://foo.com/a/b/c?d=1' URI.parse(URL).host # => "foo.com" URI.parse(URL).path # => "/a/b/c" URI.parse(URL).query # => "d=1"

Ruby's Enumerable module includes reject and select which make it easy to loop over an array or enumerable object and reject or select elements from it:

(1..3).select{ |i| i.even? } # => [2] (1..3).reject{ |i| i.even? } # => [1, 3]

Using all that you could check the host of a URL for sub-strings and reject any you don't want:

require 'uri' %w[ http://www.speedtest.net/ http://webcache.googleusercontent.com/search%3Fhl%3Den%26biw%26bih%26q%3Dcache:M47_v0xF3m8J ].reject{ |url| URI.parse(url).host[/googleusercontent\.com$/] } # => ["http://www.speedtest.net/"]

Using these methods and techniques you can reject or select from an input file, or just peek into single URLs and choose to ignore or honor them.

Use modulus operator %, this makes sure character stays in range between A to Z.

char c = 'A' + shift % 26;

You can shift letters to the right, then once letter reaches Z, the next letter will be A

int main() { int row, col; for (row = 0; row < 26; row++) { for (col = 0; col < 26; col++) { char c = 'A' + (row + col) % 26; printf("%c ", c); } printf("\n"); } printf("\n"); return 0; }

1738329 0 Should I send retain or autorelease before returning objects?

I thought I was doing the right thing here but I get several warnings from the Build and Analyze so now I'm not so sure. My assumption is (a) that an object I get from a function (dateFromComponents: in this case) is already set for autorelease and (b) that what I return from a function should be set for autorelease. Therefore I don't need to send autorelease or retain to the result of the dateFromComponents: before I return it to the caller. Is that right?

As a side note, if I rename my function from newTimeFromDate: to gnuTimeFromDate the analyzer does not give any warnings on this function. Is it the convention that all "new*" methods return a retained rather than autoreleased object?

In Memory Management Programming Guide for Cocoa it says "A received object is normally guaranteed to remain valid within the method it was received" and that "That method may also safely return the object to its invoker." Which leads me to believe my code is correct.

However, in Memory Management in Cocoa it says "Assume that objects obtained by any other method have a retain count of 1 and reside in the autorelease pool. If you want to keep it beyond the current scope of execution, then you must retain it." Which leads me to think I need to do a retain before returning the NSDate object.

I'm developing with Xcode 3.2.1 on 10.6.2 targeting the iPhone SDK 3.1.2.

screenshot of build/analyze output

Here's the code in case you have trouble reading the screen shot:

//============================================================================ // Given a date/time, returns NSDate for the specified time on that same day //============================================================================ +(NSDate*) newTimeFromDate:(NSDate*)fromDate Hour:(NSInteger)hour Minute:(NSInteger)min Second:(NSInteger)sec { NSCalendar* curCalendar = [NSCalendar currentCalendar]; const unsigned units = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit; NSDateComponents* comps = [curCalendar components:units fromDate:fromDate]; [comps setHour: hour]; [comps setMinute: min]; [comps setSecond: sec]; return [curCalendar dateFromComponents:comps]; }

Hmmm, nice puzzle. FWIW: printf("%s 1 \n", str) prints ' 1 rty "what"' ?!? ... looks to me like what you are seeing on the console, right?) is:

qwerty "what"

followed by return (no line feed), overwritten by:

' 1 '

then \n

This suggests that the string you are supplying (from a file?) includes a terminating return character.

The classic answer to such questions is to create a SQL VIEW.

Views are like dynamic virtual tables - in queries you use the view name instead of a table name, and the DBMS runs the query defined by the view to produce the rows for the query on the view. You therefore see rows based on the data from the tables at the time you access the view, not at the time the view was created.

You would create this view with a statement such as

CREATE VIEW PROT_WITH_UNITS AS SELECT * FROM dna_extraction_protocols P JOIN measurement_units M ON P.volume_unit = M.id

This will give you a view with all columns of both tables, pre-joined on (what I presume to be) the required foreign key.

If you get the definition wrong you can drop views just like tables, so you should get there eventually.

You could do this with a bit simpler logic using KeyPress instead, like this:

string buffer = ""; //buffer to store what the user typed: n, no, not, etc... void gkh_KeyPress(object sender, KeyPressEventArgs e) { buffer += e.KeyChar; //add key to the buffer, then check if we've made progress if (buffer.IndexOf("note") > -1) { this.Show(); //"notes" matched completely buffer = ""; //reset for another run } else if ("note".IndexOf(buffer) != 0) { buffer = ""; //Another key not in sequence was hit } }

3434046 0 Problem in M3G rendering in J2ME

I have made 3 planes and positioned them in a way that they make a corner of cube. (For some reasons I don't want to make a cube object). The 3 planes have 3 different Texture2Ds with different images. The strange problem is when I render the 3 objects and start rotating the camera, in some perspectives some parts of these 3 planes don't get rendered. For example when I look straight at the corner a hole is created which is shaped as a triangle. This is the image of the problem in a netbeans emulator: alt text I put the red lines there so you can see the cube better. The other strange thing is that the problem resolves when I set the scale of the objects to 0.5 or less. By the way the camera is in its default position and the cube's center is at (0,0,0) and each plane has a width and height of 2. Does anyone have any ideas why these objects have a conflict with each other and how could I resolve this problem.

Thanks in advance

I've found what happens, and it can be usefull for others. @Mark Ormston was not so far : Cookies set with path /cas are send by IE10 to URL beginings with /cas-services

In my case /cas and /cas-services are not in the same WebApp and each have its own JSESSIONID. Sending JSESSIONID created for /cas to /cas-services lead to the problem describe above.

To correct, I simply rename /cas-services with /app-services (I guess that everything not beginning with /cas should work).

<xsl:if test=" preceding-sibling::node()[ (self::a and @attr1='a1') or (self::b and @attr2='b1') ] or following-sibling::node()[ (self::a and @attr1='a1') or (self::b and @attr2='b1') ] "> ... </xsl:if>

Anand S Kumar's answer doesn't round to the nearest quarter hour, it cuts off the minutes to the nearest 15 minutes below it.

Actually, in your example 2015-07-18 13:53:33.280 should round to 2015-07-18 14:00:00.000 since 53:33.280 is closer to 60 minutes than 45 minutes.

I found an more robust answer for rounding in this post.

For your situation this should work:

import datetime def round_time(time, round_to): """roundTo is the number of minutes to round to""" rounded = time + datetime.timedelta(minutes=round_to/2.) rounded -= datetime.timedelta(minutes=rounded.minute % round_to, seconds=rounded.second, microseconds=rounded.microsecond) return rounded dt['dtcolumn'] = df['dtcolumn'].apply(lambda x: round_time(x))

You can use the collect_max UDF from Brickhouse ( http://github.com/klout/brickhouse ) to solve this problem, passing in a value of 1, meaning that you only want the single max value.

select array_index( map_keys( collect_max( carrier_id, meandelay, 1) ), 0 ) from flightinfo;

Also, I've read somewhere that the Hive max UDF does allow you to access other fields on the row, but I think its easier just to use collect_max.

The problem I have is that using config such as that shown below causes Windsor to report that "A cycle was detected when trying to resolve a dependency."

windsor.Register( Component .For<IService>() .ImplementedBy<CompositeService>(), Component .For<IService>() .ImplementedBy<ConcreteService1>(), Component .For<IService>() .ImplementedBy<ConcreteService2>() );

This cyclic behaviour seems to be at odds with the standard (non-collection based) behaviour that can be used to implenent the decorator pattern, where the component being resolved is ignored and the next registered component that implements the same interface is used instead.

So what I'd like to know is whether or not there is a way to make Windsor exclude the CompositeService component when it's resolving the IService services for the decoratedServices property. The decoratedServices property should contain two items: an instance of ConcreteService1, and an instance of ConcreteService2. I'd like to do this without explicitly specifying the dependencies.

Yes, you can just use +- operators if you want to add or subtract two numbers.

If you want to truncate the result back to 16 bits, just assign the result to a 16 bit wire/register, and it will automatically drop the upper bits and just assign the lower 16 bits to out. In some cases this may create a lint warning, so you may want to assign the result to an intermediate variable first, and then do an explicit part select.

wire [15:0] out; wire [15:0] A; wire [31:0] A_rotate; A_rotate = {A,A} << N; out = A_rotate[15:0];

Can an aggregates invariant include a rule based on information from elsewhere?

Aggregates can always use the informations in their own states and the argument that their commands recieves.

Someone use to access applicative services via singletons, service locators and so on, but IMO, that's a smell of tightly coupled applications. They forget that methods' arguments are effective dependency injectors! :-)

In DDD can an aggregates invariant include a rule based on information in a another aggregate?

No.
Except if the second aggregate is provided via commands' arguments, of course.

WARNING ! ! !

I have an entity called Asset (equipment)...
... (and a) second aggregate called AssetType...

The last time that I had to cope with a similar structure, it was a pain.

Chances are that you are choosing the wrong abstractions.

have I got my invariant wrong?

Probably... Did you asked to the domain expert? Does he talks about "TagTypes"?

You should never abstract on your own.

Entities of type X holding a reference to an instance of an X-Type are almost always a smell of over-abstraction, that in the hope of reuse, makes the model rigid and inflexible to business evolution.

ANSWER

If (and only if) the domain expert actually described the model in these terms, a possible approach is the following:

you can create an AssetType class with a factory method that turns an IEnumerable<Tag> into a TagSet and throws either MissingMandatoryTagException or UnexpectedTagException if some of the tag is missing or unexpected.
in the Asset class, a command RegisterTags would accept an AssetType and an IEnumerable<Tag>, throwing the MissingMandatoryTagException and WrongAssetTypeException (note how important are exceptions to ensure invariants).

edit
something like this, but much more documented:

public class AssetType { private readonly Dictionary<TagType, bool> _tagTypes = new Dictionary<TagType, bool>(); public AssetType(AssetTypeName name) { // validation here... Name = name; } /// <summary> /// Enable a tag type to be assigned to asset of this type. /// </summary> /// <param name="type"></param> public void EnableTagType(TagType type) { // validation here... _tagTypes[type] = false; } /// <summary> /// Requires that a tag type is defined for any asset of this type. /// </summary> /// <param name="type"></param> public void RequireTagType(TagType type) { // validation here... _tagTypes[type] = false; } public AssetTypeName Name { get; private set; } /// <summary> /// Builds the tag set. /// </summary> /// <param name="tags">The tags.</param> /// <returns>A set of tags for the current asset type.</returns> /// <exception cref="ArgumentNullException"><paramref name="tags"/> is <c>null</c> or empty.</exception> /// <exception cref="MissingMandatoryTagException">At least one of tags required /// by the current asset type is missing in <paramref name="tags"/>.</exception> /// <exception cref="UnexpectedTagException">At least one of the <paramref name="tags"/> /// is not allowed for the current asset type.</exception> /// <seealso cref="RequireTagType"/> public TagSet BuildTagSet(IEnumerable<Tag> tags) { if (null == tags || tags.Count() == 0) throw new ArgumentNullException("tags"); TagSet tagSet = new TagSet(); foreach (Tag tag in tags) { if(!_tagTypes.ContainsKey(tag.Key)) { string message = string.Format("Cannot use tag {0} in asset type {1}.", tag.Key, Name); throw new UnexpectedTagException("tags", tag.Key, message); } tagSet.Add(tag); } foreach (TagType tagType in _tagTypes.Where(kvp => kvp.Value == true).Select(kvp => kvp.Key)) { if(!tagSet.Any(t => t.Key.Equals(tagType))) { string message = string.Format("You must provide the tag {0} to asset of type {1}.", tagType, Name); throw new MissingMandatoryTagException("tags", tagType, message); } } return tagSet; } } public class Asset { public Asset(AssetName name, AssetTypeName type) { // validation here...

29047409 0

the answer is YES and NO. it depends on the processed data dynamic range

if you are processing numbers/signal in specified range then YES
but if the numbers/signal has very high dynamic range then NO

you should use more fixed point formats for different stage of signal processing

for example ADC gives you values in exact defined range
so you have to use fixed format such that does not loss precision and have not many unused bits
after that you apply some filter or what ever the range changes
so you need to get bound of possible number ranges per stage and use the best suited fixed point format you have at disposal

This means you need some number of fixed point formats

and also the operations between them
you can have fixed number of bits and just change the position of decimal point...

To be more specific then you need add the block diagram of your processing pipeline

with the number ranges included
and list of used operations
matrix operations and integrals/sums are tricky because they can change the dynamic range considerably

The real question always stays if such implementation is faster then floating point ...

because sometimes the transition between different fixed point stages can be slower then direct floating point implementation ...

I am trying to use XML, RCurl package to read some html tables of the following URL http://www.nse-india.com/marketinfo/equities/cmquote.jsp?key=SBINEQN&symbol=SBIN&flag=0&series=EQ#

Here is the code I am using

If you look at the tables it has not been able to parse the values from the webpage. I guess this due to some javascipt evaluation happening on the fly. Now if I use "save page as" option in google chrome(it does not work in mozilla) and save the page and then use the above code i am able to read in the values.

But is there a work around so that I can read the table of the fly ? It will be great if you can help.

You can simplify to:

SELECT expire_date - (expire_date - now()) - interval '1 month' FROM "License" WHERE license_id = 10

This is valid without additional brackets because subtractions are evaluated from left to right.
_{In my first version the one necessary pair of brackets was missing, though.}

This form of the query also prevents an error in the case that license should not be unique. You would get multiple rows instead. In that case, and if you should need it, add LIMIT 1 guarantee a single value.

@Milen diagnosed the cause of the error correctly. Experiment with these statements to see:

SELECT interval (interval '1 month'); -- error SELECT (interval '1 month')::interval; -- no error

However, the cure is simpler. Just don't add another cast, it is redundant.

Correct way to solve this issue is as follows:

Template.DoPolls.helpers({ polls: function() { var user = Meteor.userId() return Polls.find({voters: {$ne: user}}); } });

where $ne look over the voters array and if it finds the userId then doesn't show that poll.

To achieve the opposite (so only polls where the user has voted the helper would be:

Template.PollsDone.helpers({ polls: function() { var user = Meteor.userId() return Polls.find({voters: {$in: [ user ] }}); } });

If I want to add 0x0i (were i is an unsinged int between 0 and 9), what could I do?

EDIT: I probably wasn't quite clear. So by 0x01, I mean the character given in Hex as 01. So in the above if i is the integer (in decimal) say 3, then I would want to add 0x03 (so this is not the character given in decimal as 48 + 3).

One difference I can think of is, the way you bind HTML/ASP controls

--HTML button control-- <input type = "button" id = "myButtonHTML" /> --ASP button control-- <asp:button runat = "server" id = "myButtonASP" />

the way you bind this in javascript will be as follows

--HTML control-- document.getElementById("#myButtonHTML").value AND --ASP control-- document.getElementById("#myButtonASP.ClientID").value

Adding belong_to and has_many lines to your models makes Rails aware of their relationship and generates helper methods, but does not create FKs at the database level. To do that, you need to create and run a migration:

rails g migration add_level_id_to_students level_id:integer

then rake db:migrate

If you want to generate a model with the foreign key part of it, you can use the references shortcut: rails g model Student name:string level:references

It means literally in the shape of the Greek letter rho, which is "ρ". The idea is that if you map the values out as a graph, the visual representation forms this shape. You could also think of it as "d" shaped or "p" shaped. But look carefully at the font and notice that the line or stem extends slightly past the loop, while it doesn't on a rho. Rho is a better description of the shape because the loop never exits; i.e., there shouldn't be any lines leading out of the loop. That and mathematicians love Greek letters.

You have some number of values which do not repeat; these form a line or the "stem" of the "letter". The values then enter a loop or cycle, forming a circle or the "loop" of the "letter".

For example, consider the repeating decimals 7/12 (0.5833333...) and 3227/55 (5.81441441444...). If you make your sequence the digits in the number, then you can graph these out to form a rho shape. Let's look at 3227/55.

x0 = 5
x1 = 8
x2 = 1
x3 = 4
x4 = 4
x5 = 1 = x2
x6 = 4 = x3
x7 = 4 = x4
...

You can graph it like so:

5 -> 8 -> 1 ^ \ / v 4 <- 4

You can see this forms a "ρ" shape.

Use Inversion Of Control (IOC) and the Service Locator pattern to create a shared data service they both talk too. I notice your mvvm-light tag; I know a default Mvvm-light project uses a ViewModelLocator class and SimpleIOC so you can register a data service like below.

public class ViewModelLocator { static ViewModelLocator() { ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default); SimpleIoc.Default.Register<IDataService, DataService>(); } }

An interface is used so we can swap out the DataService at will and even have a different one for design time. So you will create an interface that defines methods you will use and just make sure your DataService implements them. It is in your DataService implementation you will use the shared context / source.

public class DataService: IDataService { //USE SAME SOURCE (example EF) private SharedSourceEntities context; (blah blah)... }

After you can inject it into both view models either in the constructor or calling the service locator.

Dependency Injection:

public class ViewModelOne: ViewModelBase { private readonly IDataService dataService; public ViewModelOne(IDataService dataService) { this.dataService = dataService; } } public class ViewModelTwo: ViewModelBase { private readonly IDataService dataService; public ViewModelTwo(IDataService dataService) { this.dataService = dataService; } }

Service location:

SimpleIoc.Default.GetInstance<IDataService>();

Also tried to make a smaller step and add foreign key just for 'from field:

ALTER TABLE `messages` ADD CONSTRAINT `messages_users_fk` FOREIGN KEY (`from` ) REFERENCES `users` (`id` ) ON DELETE SET NULL ON UPDATE CASCADE , ADD INDEX `messages_users_fk_idx` (`from` ASC) ;

The error is slightly different: ERROR: Error 1825: Failed to add the foreign key constraint on table 'messages'. Incorrect options in FOREIGN KEY constraint 'cook4food/messages_users_fk'.

The types of the fields are the same (bigint(20) NOT NULL) as it was suggested as the cause of the problem in other StackOverflow threads. My tables are not partitioned (MySQL manual states this as a limitation for having foreign key constraints in InnoDB). The 'messages' table stores no rows currently, so data stored can't be the issue in any manner. I'm stuck, please help.

Your option #1 is not appropriate as written but close to an approach you should probably consider. You can add nest the views of different UIViewControllers however when you do so you should use the methods described in Managing Child View Controllers in a Custom Container so that the parent controller correctly manages its child controllers.

For example, :vimgrep /pattern/ file | copen

Does it act like a pipe in Linux Command Line? Contents of vimgrep gets piped to copen?

Or does it separate commands like ; in Command Line?

22402603 0 test browser supports the style or not

I can do the following to check if the browser doesn't support column-count css3 property then use my own code:

if (!('WebkitColumnCount' in document.body.style || 'MozColumnCount' in document.body.style || 'OColumnCount' in document.body.style || 'MsColumnCount' in document.body.style || 'columnCount' in document.body.style)) {//my own code here}

But how can I check that background-image animation support?

This type of changing image source with css3 only works on chrome browsers.

0%{background-image: url(image-1);} 50%{background-image: url(image-2);} 100%{background-image: url(image-3);}

So, I wanted to know is there any technique that we can test that it is supported by the browser or not?

Update

I just tried like this code which is even not checking @keyframes style support:

if (('@keyframes' in document.body.style || '@-webkit-keyframes' in document.body.style)) { //if(!('from' in @keyframes || 'from' in @webkit-keyframes)){ //code in here alert('test'); //} }

So even can I not test that @keyframes supported by browser or not?

Solution:

I've found from mdn

var animation = false, animationstring = 'animation', keyframeprefix = '', domPrefixes = 'Webkit Moz O ms Khtml'.split(' '), pfx = ''; if( elm.style.animationName !== undefined ) { animation = true; } if( animation === false ) { for( var i = 0; i < domPrefixes.length; i++ ) { if( elm.style[ domPrefixes[i] + 'AnimationName' ] !== undefined ) { pfx = domPrefixes[ i ]; animationstring = pfx + 'Animation'; keyframeprefix = '-' + pfx.toLowerCase() + '-'; animation = true; break; } } }

An accept handler may only take an error code as a parameter, see: AcceptHandler.

I recommend making acceptor a member of CServerSocket then changing the call to async_accept to:

acceptor.async_accept(*socket, std::bind(&CServerSocket::OnAccept, this, std::placeholders::_1));

and accessing acceptor within the OnAccept member function.

The problem is that you're assigning the return value of volunteer.time_in.push back to volunteer.time_in. The return value is the new length of the array, not the array itself.

So change that line to just:

volunteer.time_in.push(date);

25770507 0 Creating instances of a covariant type class from instances of a non-covariant one

Suppose I've got a simple type class whose instances will give me a value of some type:

trait GiveMeJustA[X] { def apply(): X }

And I've got some instances:

case class Foo(s: String) case class Bar(i: Int) implicit object GiveMeJustAFoo extends GiveMeJustA[Foo] { def apply() = Foo("foo") } implicit object GiveMeJustABar extends GiveMeJustA[Bar] { def apply() = Bar(13) }

Now I have a similar (but unrelated) type class that does the same thing but is covariant in its type parameter:

trait GiveMeA[+X] { def apply(): X }

In its companion object we tell the compiler how to create instances from instances of our non-covariant type class:

object GiveMeA { implicit def fromGiveMeJustA[X](implicit giveMe: GiveMeJustA[X]): GiveMeA[X] = new GiveMeA[X] { def apply() = giveMe() } }

Now I'd expect implicitly[GiveMeA[Foo]] to compile just fine, since there's only one way to get a GiveMeA[Foo] given the pieces we have here. But it doesn't (at least not on either 2.10.4 or 2.11.2):

scala> implicitly[GiveMeA[Foo]] <console>:16: this.GiveMeA.fromGiveMeJustA is not a valid implicit value for GiveMeA[Foo] because: hasMatchingSymbol reported error: ambiguous implicit values: both object GiveMeJustAFoo of type GiveMeJustAFoo.type and object GiveMeJustABar of type GiveMeJustABar.type match expected type GiveMeJustA[X] implicitly[GiveMeA[Foo]] ^ <console>:16: error: could not find implicit value for parameter e: GiveMeA[Foo] implicitly[GiveMeA[Foo]] ^

If we get rid of our irrelevant GiveMeJustA instance, it works:

scala> implicit def GiveMeJustABar: List[Long] = ??? GiveMeJustABar: List[Long] scala> implicitly[GiveMeA[Foo]] res1: GiveMeA[Foo] = GiveMeA$$anon$1@2a4f2dcc

This is in spite of the fact that there's no way we can apply GiveMeA.fromGiveMeJustA to this instance to get a GiveMeA[Foo] (or any subtype of GiveMeA[Foo]).

This looks like a bug to me, but it's possible that I'm missing something. Does this make any sense? Is there a reasonable workaround?

Here is the WMI way to find it. I give you the PowerShell writting, but you can transform it for VBScript or C# easily

PS C:\> (Get-WmiObject Win32_NTDomain).DomainName

Be careful, the Domain part of the 'pre windows 2000 domain' can be completly different from the user Principal Name (user@domain) use to logon onto Active-Directory. the DOMAIN is the Primary Domain Controleur name or the Netbios domain name. DOMAIN is created during domain creation, by default it's part of the DNS name, but it can be completly changed during domain creation.

You can find it with nETBIOSName attribute :

ldifde -f netbios.ldf -d "CN=Partitions,CN=Configuration,DC=your-DNS-Name" -r "(netbiosname=*)"

Edited

Here is the CSharp code

ManagementObjectSearcher domainInfos1 = new ManagementObjectSearcher("select * from WIN32_NTDomain"); foreach (ManagementObject domainInfo in domainInfos1.Get()) { Console.WriteLine("Name : {0}", domainInfo.GetPropertyValue("Name")); Console.WriteLine("Computer/domain : {0}", domainInfo.GetPropertyValue("Caption")); Console.WriteLine("Domain name : {0}", domainInfo.GetPropertyValue("DomainName")); Console.WriteLine("Status : {0}", domainInfo.GetPropertyValue("Status")); }

21386161 0 SVN confusion: "local add, incoming add upon merge" What do the words actually refer to?

I'm pretty new to subversion and the docs just aren't making sense to me. I was wondering if someone could break down this error message (from svn st) into plain English, as well as the other one I get local delete, incoming delete upon merge.

To be precise about my question:

What does local add (or local delete) refer to?
What does incoming add (or incoming delete) refer to?

What's mystifying to me is that the branch has absolutely nothing to do with the files that receive these errors. In other words, it doesn't add or delete any of these files locally (what I presume local add/delete means). Besides, if I had deleted the file locally, why would that be in conflict with a deletion in the repo (incoming) anyway?

Background Information

How I got here: I merged trunk into my branch and am trying to commit to my branch.

P.S. I've (tried to) read Managing trunk and feature branches: local delete, incoming delete upon merge, but there's too much terminology. Other questions/answers I've read here on SO don't seem to apply or else are hard to understand.

36522860 0 Android studio - unwanted tab dragging

I have an EXTREMELY annoying problem with Android Studio. Scenario:

1) Switch tabs by clicking on a tab;

2) First action in the new tab is to highlight some code via the mouse.

In some cases dragging the mouse after the left click drags the tab as if I'd clicked on the tab and wanted to reposition it.

I have not been able to discern any pattern to the phenomenon; for example, the time between switching tabs and the left click, the position of the left click.

Any suggestions as to how to stop this?

I have a bunch of files that I need to look at. All lines in these files end in ^M (\x0D) except the very last line that ends in ^M^J (\x0D\x0A).

some text foo^Mmore text and^Ma few control-m^Ms and more and more

752490 0 Security risks of an un-encrypted connection across an international WAN?

The organisation for which I work has an international WAN that connects several of its regional LANs. One of my team members is working on a service that receives un-encrypted messages directly from a FIX gateway in Tokyo to an app server in London, via our WAN. The London end always initiates the authenticated connection, and at no point do these messages leave our WAN.

But our local security guru suggests that we should be encrypting these messages as a WAN apparently has significantly more security risk than a LAN. How much easier is it really to break into a WAN than a LAN? And what other security risks does a WAN pose in this context?

UPDATE: Many thanks for your answers. I've decided to encrypt the connection, mainly because it's clear that the WAN does introduce extra security vulnerabilities due to the hardware being outside of our physical control.

There is a command to show all the commit logs history since the beginning in a branch

git log

after execting this command, you will find that each commit or log has commit id and Author with its date, copy the commit ID and right this command:

git show COMMIT_ID

The command above will show the commit details by the author assigned to this commit id

Another solution it to write something like this:

git whatchanged --since '04/14/2013' --until '05/22/2014'

The code above it like git log however with filters (range)

My simple answer combined with those answer is:

Create your application/program using thread safety manner
Avoid using public static variable in all places

Therefore it usually fall into this habit/practice easily but it needs some time to get used to:

program your logic (not the UI) in functional programming language such as F# or even using Scheme or Haskell. Also functional programming promotes thread safety practice while it also warns us to always code towards purity in functional programming. If you use F#, there's also clear distinction about using mutable or immutable objects such as variables.

Since method (or simply functions) is a first class citizen in F# and Haskell, then the code you write will also have more disciplined toward less mutable state.

Also using the lazy evaluation style that usually can be found in these functional languages, you can be sure that your program is safe fromside effects, and you'll also realize that if your code needs effects, you have to clearly define it. IF side effects are taken into considerations, then your code will be ready to take advantage of composability within components in your codes and the multicore programming.

10781084 0 If my app deletes a post it made to a user's wall, will all likes and shares made by other people also be deleted?

Lets say I have a FB app I've created, and for whatever reason the server code for the app is responsible for posting stories to the app user's wall (using a token).

Now let's say we want to take down that post at a later date - easy, right? Because the app created the post, it owns it, and using the ID it received originally it can take that post down. (I presume the ID I get back is actually an "object id" referring to my content, rather than specifically to the post on the user's wall - correct?)

Here's the thing though. What if one or more friends of the user shared that story to their own wall - what if this happened a number of times, spreading through the friend relationship tree further and further. Does my app still have the power to remove all of these posts, because it created the original post?

Additionally, what if the original user deleted the post themselves from their wall, but not until it had been shared by his/her friends? Would this have the same effect (delete everywhere), or would it only be that one specific post being removed? Would my app get an error when it tried to delete the post itself if the post had already been deleted by the user?

The reason I ask is because, if my app deleted the original post that it made to the user's wall, I would want all of the shared posts or likes to also be deleted, no matter where they were down the friend chain. I don't want to delete my original post and assume all is well, only to discover that because it was shared several times down the chain that it is still visible somewhere.

In case it's relevant, the "post" my app will make would require a custom image and a specific return URL - I tried the /user_id/links graph API and it didnt work (there's a bug with it). So I'd be most likely using /user_id/feed to make the post.

The title might seems weird, but I don't really know how to describe this situation as I'm a beginner in JavaScript.

Here's the code :

a={}; var b=a; b['a']='x'; console.log(a);

the result will be:

Object { a="x"}

shouldn't it be a blank object because I set 'x' to variable b only ?

You can coerce a CF type to an NS type by first re-binding the CFMakeCollectable function so that it takes 'void *' and returns 'id', and then using that function to perform the coercion:

ObjC.bindFunction('CFMakeCollectable', [ 'id', [ 'void *' ] ]); var cfString = $.CFStringCreateWithCString(0, "foo", 0); // => [object Ref] var nsString = $.CFMakeCollectable(cfString); // => $("foo")

To make this easier to use in your code, you might define a .toNS() function on the Ref prototype:

Ref.prototype.toNS = function () { return $.CFMakeCollectable(this); }

Here is how you would use this new function with a CFString constant:

ObjC.import('CoreServices') $.kUTTypeHTML.toNS() // => $("public.html")

Is Task a specific case where we rely on the native javascript implementation of Task?

Exactly. You'll notice that Task the type but not Task the tag (thing on the right) are exported from the module, so you can't actually access the latter. It's a placeholder to make the type system happy.

Instead, the Native JavaScript implementation knows what tasks really are, which is a JS object. Any native module dealing with Tasks (either the Task module or any third-party library like elm-http) is in on the secret. However, the Task module exports a good number of helper functions that you can have a lot of control over tasks using only the already published libraries.

Clarification Edit: Yes, you need to use a third-party library to get a task that actually does some effect in the outside world. To actually run that task, you need to send it out a port; until you do that a Task is just a description of the work to do.

Your conversion atof in this code

for(k = 0; k < 361; k++) { val = atof(result[k]); cal[k] = val; }

is going out of bounds of the array 'result'
You only allocate memory to elements in the result array when you have data to put in it

result[i] = malloc(strlen(value) + 1);

If less than 361 records were created you are reading from unallocated memory - hence the error.

You need to keep a record of how many results you have read in and then use that value to ensure that you remain in range as you process the result array.

There is no difference between files based on the file extension.

28241767 0 CSS content of input value before the input in a td element

I have to print a pretty hefty page / form / table combination and when I print I have multiple text input elements that I can't seem to reduce the width to use only the width needed to display the text without excess width. That excess width effects the ten required columns I have to print.

So I've attempted to use CSS Content to move the text from the text input elements in to the parent table data elements. Here is example HTML and CSS:

<td><input type="text" value="Deadly Ninja Robots" /></td>

The CSS I have tried:

form fieldset input[type='text'] {display: none;} form fieldset input[type='text']:before {content: form fieldset input[type='text'](value) ": ";}

How do I take the value of text input elements and display them inside the table data element that is the direct parent of the text input element itself?

28714815 0 Calculating CRC initial value instead of appending the CRC to payload

Most of the CRCs I've implemented were appending the calculated CRC value to the message (payload) and checking for a zero result at the receiver after all bytes incl. CRC value were fed through the CRC register. Obviously this is a quite standard approach.

Now I would like to use a different approach:

Calculate a value from the payload.
Use that value as initial value for the CRC register before the message bytes (payload) are fed through the CRC register such that the result after the last byte of the payload was fed through will be zero.

What is the best approach to do this? Does one have a good idea or some pointers where to dig deeper?

ps: Why I want to do this? In some applications (ROM) I cannot append data as the data is stored at the end of address space of a ROM. So I'd like to either preload the CRC register or prepend the value to the message.

You need to make a concatenation in php

in your example use "." instead of "+"

$string = $userNode->getFirstName() . $userNode->getLastName();

12420251 0

The expression [[]] actually consists of two concatenated subexpressions: [[] and ].

[[] is character class that matches only [ characters. Having [ is only possible at the very beginning of a character class.
] is just a normal character if outside of a character class.

Both are concatenated thus your expression matches any character of [ followed by ], which results in matching [].

Your regular expression is self-contradictory.

You are bounding your pattern on word boundaries, and then including a non-word character in the string you're looking for. Since the '.' character isn't a word character, there will never be any strings that are delimited by word boundaries that include the '.'.

Put another way, since the '.' is itself a word boundary, you are looking for [word-boundary][word-boundary][word], which cannot occur.

Just take out the word boundaries in your REGEXP:

WHERE INET_NTOA(ip) REGEXP '\.111'

20045738 0 DLL deployment increases startup time of Sitecore site

We have a Sitecore 6.6 instance which is used to host multiple sites. It is hosted in IIS 7.5. We developed custom Sitecore sublayouts and pipelines which are used across websites.

When any dll is deployed in bin folder, the Sitecore site takes long time to startup (8-10 mins). But when IIS is reset, startup time is less (30-40 seconds).

What could be the reason for application startup time to be more for DLL deployment than IIS Reset ? Any suggestions to improve the application startup time for DLL deployment ?

Update 1: The startup time after DLL deployment impacts our build process as it increases the overall build deployment time in all environments (DEV,STG,LIVE).

Profiling snapshot of w3wp process revealed two major hotspots:

Sitecore.Threading.Semaphore.P
Sitecore.IO.FileWatcher.Worker

Update 2: After following the deployment suggested by Vicent, profiling snapshot of w3wp process revealed major hotspot at

Sitecore.Web.UI.WebControls.Sublayout.GetUserControl(Page)

Further analysis of memory dump showed that thread was waiting for JIT compilation of newly deployed DLL.

It would help if you could point to the page where the problem is reproducible, even if that means that you create a page yourself, put it in dropbox and make it public.

Did you even try to replicate the problem with the html and ruby code that you have posted? I am asking because the problem is not reproducible with the provided code. Take a look yourself:

> browser.ul( :class =>'a').li( :class =>'b').link(:class =>'c').span(:class =>'d') => #<Watir::Span:0x..fa66c75ff618434cc located=false selector={:class=>"d", :tag_name=>"span"}> > browser.ul( :class =>'a').li( :class =>'b').link(:class =>'c').span(:class =>'d').text => "text"

As far as I understood, you are surprised that when you provide some code, Watir returns an element, but when you want to execute a method on the element, it complains that it can not find the element.

Take a closer look at the ruby object that represents element on a page:

#<Watir::Span:0x..fa66c75ff618434cc located=false selector={:class=>"d", :tag_name=>"span"}>

Please notice located=false. As far as I know, that means that watir creates a ruby object before trying to access it, so the first line of your code does not raise any exceptions. But then when you try to use the element, watir can not find it on the page and complains.

A few recommendations I would like to make (based on the app we've built which also uses Table Storage exclusively).

Introduce a new entity called Account or Subscription. You can use a GUID to uniquely identify an account.
Along with user information (user id, password etc.) in the user's table, store the account information as well. So at all times when you're authenticating a user, you're making point queries. Also store the user's role (Member or Owner) in the user's table. Doing this way, you would know if the user is an individual user or part of a team. If the user is part of a team, then what the role of that user in that team (Owner or Member).
Store 2 copies of user data. First copy is what you're using now. Second copy essentially associate a user with an account where the PartitionKey of the second copy is the account id and row key is the PartitionKey of the first copy. This will help you find the users in a particular team.

Individual User Login Scenario

So an individual user logs in using their username/password. You retrieve the information about the user and there you find out that the user is an individual user based on the account type.

Team Owner Login Scenario So when a team owner logs in, based on the login you will find out that the user is a team owner. If the team owner needs to find the list of all the users in the team, you do another query (it will be the PartitionKey query only) which will give you information about all the users in the team.

Team User Login Scenario

So when a team user logs in, based on the login you will find out that the user is a team user. Since the user is a team user, he/she need not query the table to find out about other users in the team. Even if they do, you will do another query (same as team owner query) to get the list of users in a team.

An EXISTS operator might be faster than the subquery:

SELECT t1.Index, MIN(t1.[Date]), MAX(t1.[Date]) FROM myTable t1 WHERE EXISTS (SELECT * FROM myTable t2 WHERE t2.Index = t1.Index AND t2.[Date] >= '1/1/2000' AND t2.[Date] < '1/1/2001') GROUP BY t1.Index

It would depend on table size and indexing I suppose. I like G Mastros HAVING clause solution too.

Another important note... if your date is actually a DATETIME and there is a time component in any of your dates (either now or in the future) you could potentially miss some results if an index had a date of 12/31/2000 with any sort of time besides midnight. Just something to keep in mind. You could alternatively use YEAR([Date]) = 2000 (assuming MS SQL Server here). I don't know if the DB would be smart enough to use an index on the date column if you did that though.

EDIT: Added GROUP BY and changed date logic thanks to the comment

Code you use for uploading images won't work in Azure. Just imagine how this should work if you scale up nubmer of instances. You should use Azure blob storage to upload files in Azure. You can google for good tutorial, but to make a long story short you should do the following:

1.) Create Azure Storage Account at manage.windowsazure.com

2.) Setup storage connection string (you can get AccountKey from you storage account)

<configuration> <appSettings> <add key="StorageConnectionString" value="DefaultEndpointsProtocol=https;AccountName=storagesample;AccountKey=nYV0gln9fT7bvY+rxu2iWAEyzPNITGkhM88J8HUoyofpK7C8fHcZc2kIZp6cKgYRUM74lHI84L50Iau1+9hPjB==" /> </appSettings> </configuration>

In Your code

3.) Add following namespaces

using Microsoft.WindowsAzure.Storage; using Microsoft.WindowsAzure.Storage.Auth; using Microsoft.WindowsAzure.Storage.Blob;

4.) Initialize Storage Connection

CloudStorageAccount storageAccount = CloudStorageAccount.Parse( ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString); CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

5.) Create container, if it diesn't exist

// Retrieve a reference to a container. CloudBlobContainer container = blobClient.GetContainerReference("mycontainer"); // Create the container if it doesn't already exist. container.CreateIfNotExists(); container.SetPermissions( new BlobContainerPermissions { PublicAccess = BlobContainerPublicAccessType.Blob });

6.) Specify object name

// Retrieve reference to a blob named "myblob". CloudBlockBlob blockBlob = container.GetBlockBlobReference("myblob");

7.) Upload fata

MemoryStream ms = new MemoryStream();
Image img = Image.FromStream(model.ImageUpload.InputStream);
img.Save(ms, ImageFormat.Jpeg);

// Create or overwrite the "myblob" blob with contents from file. blockBlob.UploadFromStream(ms.ToArray());

If waiting and upgrading the gsa software to v 7.2,.coming mid December is an option you will have wild card search built in.

Otherwise you have to dig deeper. A possible option is a document filter. If you are interested in that option I might be able to help.

22727318 0 How can I get a CAAnimation to call a block every animation tick?

Can I somehow have a block execute on every "tick" of a CAAnimation? It could possibly work like the code below. If there's a way to do this with a selector, that works too.

NSString* keyPath = @"position.x"; CGFloat endValue = 100; [CATransaction setDisableActions:YES]; [self.layer setValue:@(toVal) forKeyPath:keyPath]; CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:keyPath]; animation.duration = 1; animation.delegate = self; __weak SelfClass* wself = self; animation.eachTick = ^{ NSLog(@"Current x value: %f", [wself valueForKeyPath:keypath]); }; [self.layer addAnimation:animation forKey:nil];

It is almost impossible to answer your question in the scope of a SO "answer" - you will need to read up on implementation of parallel processing for the particular architecture of your machine if you want the "real" answer. Short answer is "it depends". But your program could be running on both processors, on any or all of the four cores; they key to understand here is that you can control that to some extent with the structure of your program, but the neat thing about OMP is that usually "you ought not to care". If threads are operating concurrently, they will usually get a core each; but if they need to access the same memory space that may slow you down since "short term data" likes to live in the processor's (core's) cache, and that means there is a lot of shuffling data going on. You get the greatest performance improvements if different threads DON'T have to share memory.

38514855 0 Toolbar/Nav drawer not working with tabbed view

I'm having an issue getting my toolbar and navigation drawer to show on a new layout file. It's working for the whole app, except the new tabbed layout view.

I try to activate it in the onCreate of the new java class:

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.workout_days); mToolBar = activateToolbar(); setUpNavigationDrawer();

I no longer get an error, but the toolbar still doesn't show up. I'm wondering if it's something wrong with my layout file.

baseactivity:

public static final int HOME = 1; public static final int MY_WORKOUT = 2; public static final int MAXES = 3; public static final int PROGRESS = 4; public static final int WORKOUTS = 5; public static final int HELP = 6; private Class mNextActivity; public static String mTitle = AppConstant.SHIEKO_WORKOUT; public static int mType = HOME; protected Toolbar mToolBar; private NavigationDrawerFragment mDrawerFragment; protected Toolbar activateToolbar() { if(mToolBar == null) { mToolBar = (Toolbar) findViewById(R.id.app_bar); setSupportActionBar(mToolBar); switch (mType) { case HOME: getSupportActionBar().setTitle(AppConstant.SHIEKO_WORKOUT); break; case MY_WORKOUT: getSupportActionBar().setTitle(AppConstant.MY_WORKOUT); break; case MAXES: getSupportActionBar().setTitle(AppConstant.SET_MY_MAXES); break; case PROGRESS: getSupportActionBar().setTitle(AppConstant.MY_PROGRESS); break; case WORKOUTS: getSupportActionBar().setTitle(AppConstant.WORKOUTS); break; case HELP: getSupportActionBar().setTitle(AppConstant.FEEDBACK); } } return mToolBar; }

Here is my activity: I also have 3 other fragment xml pages that are for the 3 tabs, those do not include the toolbar or nav bar as it's my understanding they are below the tabview.. correct me if I'm wrong please..

When items are added to a recycler view or a list view you need to notify the adapter that these changes have occurred which you aren't doing.

In onProgressUpdate you'd want to call adapter.notifyItemInserted(position) to tell the RecyclerView to refresh. To do this you'd need a callback or a listener in your AsyncTask because it doesn't have a reference to your adapter, and it shouldn't.

See here for all the notify calls you have the ability to use: https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter.html

Your code does essentially the same as:

SqlString dbString = resultReader.GetSqlString(0); string outputString = dbString.ToString();

string itself is a UNICODE string (specifically, UTF-16, which is 'almost' the same as UCS-2, except for codepoints not fitting into the lowest 16 bits). In other words, the conversions you are performing are redundant.

Your web app most likely mangles the encoding somewhere else as well, or sets a wrong encoding for the HTML output. However, that can't be diagnosed from the information you provided so far.

in order to show additional data you can use Grid or StackPanel or whatever suits your needs with visibility collapsed and when the user clicks the item it will be set to show. Here I demonstrated how you can do this with a simple ListView:

This is my MainPage:

<Page x:Class="App1.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="using:App1" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" Name="DummyPage" mc:Ignorable="d"> <Page.Resources> <local:BoolToVisibilityConverter x:Key="BoolToVisibilityConverter" /> </Page.Resources> <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <ListView Name="lvDummyData" HorizontalAlignment="Center" VerticalAlignment="Center" IsItemClickEnabled="True" ItemClick="lvDummyData_ItemClick" SelectionMode="Single"> <ListView.ItemTemplate> <DataTemplate> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBlock Text="{Binding FirstName}" /> <StackPanel Grid.Row="1" Margin="0,20,0,0" Visibility="{Binding ShowDetails, Mode=OneWay, Converter={StaticResource BoolToVisibilityConverter}}"> <TextBlock Text="{Binding LastName}" /> <TextBlock Text="{Binding Adress}" /> </StackPanel> </Grid> </DataTemplate> </ListView.ItemTemplate> </ListView> </Grid> </Page>

This is my code behind:

using System.Collections.ObjectModel; using System.ComponentModel; using Windows.UI.Xaml.Controls; // The Blank Page item template is documented at http://go.microsoft.com/fwlink/?LinkId=402352&clcid=0x409 namespace App1 { /// <summary> /// An empty page that can be used on its own or navigated to within a Frame. /// </summary> public sealed partial class MainPage : Page, INotifyPropertyChanged { public ObservableCollection<DummyData> DummyData { get; set; } private DummyData tempSelectedItem; public MainPage() { DummyData = new ObservableCollection<DummyData>(); DummyData.Add(new DummyData() { Adress = "London", FirstName = "Shella", LastName = "Schranz", ShowDetails = false }); DummyData.Add(new DummyData() { Adress = "New York", FirstName = "Karyl", LastName = "Lotz", ShowDetails = false }); DummyData.Add(new DummyData() { Adress = "Pasadena", FirstName = "Jefferson", LastName = "Kaur", ShowDetails = false }); DummyData.Add(new DummyData() { Adress = "Berlin", FirstName = "Soledad", LastName = "Farina", ShowDetails = false }); DummyData.Add(new DummyData() { Adress = "Brazil", FirstName = "Cortney", LastName = "Mair", ShowDetails = false }); this.InitializeComponent(); lvDummyData.ItemsSource = DummyData; } private void lvDummyData_ItemClick(object sender, ItemClickEventArgs e) { DummyData selectedItem = e.ClickedItem as DummyData; selectedItem.ShowDetails = true; if (tempSelectedItem != null) { tempSelectedItem.ShowDetails = false; selectedItem.ShowDetails = true; } tempSelectedItem = selectedItem; } public event PropertyChangedEventHandler PropertyChanged; public void RaisePropertyChangeEvent(string propertyName) { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); } } public class DummyData : INotifyPropertyChanged { public string FirstName { get; set; } public string LastName { get; set; } public string Adress { get; set; } private bool showDetails; public bool ShowDetails { get { return showDetails; } set { showDetails = value; RaisePropertyChangeEvent(nameof(ShowDetails)); } } public event PropertyChangedEventHandler PropertyChanged; public void RaisePropertyChangeEvent(string propertyName) { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); } } }

In my code-behind I have a variable tempSelectedItem which holds the previous clicked item so that you can hide its information.

In order to display and hide the information accordingly we need a simple BoolToVisibilityConverter:

using System; using Windows.UI.Xaml; using Windows.UI.Xaml.Data; namespace App1 { public class BoolToVisibilityConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, string language) { bool boolValue = (bool)value; return boolValue ? Visibility.Visible : Visibility.Collapsed; } public object ConvertBack(object value, Type targetType, object parameter, string language) { throw new NotImplementedException(); } } }

Hope this helps.

Yes is the answer but it's only the string.

You can use <input name="test[]" />

and you will receive an array of all inputs with name "test[]" in an array with name "test"

That's normal as your object is a reference type. You should make a deep copy in order to reflect the changments in your history list

try something like this

private void Employee_PropertyChanged(object sender, PropertyChangedEventArgs e) { var empCloned = DeepClone(this); History.Add(empCloned); //throw new NotImplementedException(); }

Deep Copy

private T DeepClone<T>(T obj) { using (var ms = new MemoryStream()) { var formatter = new BinaryFormatter(); formatter.Serialize(ms, obj); ms.Position = 0; return (T) formatter.Deserialize(ms); } }

Heroku runs a case-sensitive filesystem, whereas your OS may not be case-sensitive. Try changing that require to this instead:

 require 'card'

As a general rule of thumb, most files within Ruby are required using lowercase letters with underscores serving as a word separator, like this:

 require 'card_shuffler'

You can do exactly the same thing in C++:

std::ifstream reader( xmlInputStream.c_str() ); if ( !reader.is_open() ) { // error handling here... } std::string xml; std::string line; while ( std::getline( reader, line ) ) { xml += line + '\n'; }

It's probably not the best solution, but it's already fairly good. I'd probably write something like:

std::string xml( (std::istringstream_iterator<char>( reader )), (std::istringstream_iterator<char>()) );

(Note that at least one set of the extra parentheses are needed, due to an anomaly in the way C++ would parse the statement otherwise.)

Or even:

std::string readCompleteFile( std::istream& source ) { return std::string( std::istringstream_iterator<char>( source ), std::istringstream_iterator<char>() ); }

(Look ma, no variables:-)!) Both of these solutions preserve the newlines in the original file, so you don't need to put them back in after reading.

first, you have to give a class or id to your select HTML element.

<select class="chosen" .... //same html/php code

Then in your javascript code, you call the jQuery chosen plugin to change this select to a chosen element like this:

$(document).ready(function(){ $('.chosen').chosen(); })

and it should work, you don't have to change anything in you php code, just give a class or id to you your select element so you can get if with jQuery selector. I advice you to read the chosen documentation

Do you need all of this data present on the Windows machine? Or are you going to be accessing it intermittently?

You might try just mounting your S3 bucket.

It will still be remote but will act like a normal mounted drive in Windows. If you need to do some data crunching then copy just the files you need at that moment to the local disk. You can mount S3 with S3browser,Cloudberry, or a hundred other S3 clients.

What appeared to be happening in this case was that when the code was copied to a new part of the page the init() function was called again. Which then meant that two connections where in process.

Therefore the fan box double populated itself.

I may be missing something here, but you can call the render method on the prototype of Super in your Sub.render function :

Super = Backbone.View.extend({ render : function(){ console.log('super render'); return this; } }); Sub = Super.extend({ render : function(){ console.log('sub render'); Super.prototype.render.call(this); return this; } }); var view = new Sub(); view.render();

Is this just an example, or the real application?

In trading room environments, market data applications are extremely sensitive to delays of even a few milliseconds, and a lot of time and money is invested to minimise delays.

This makes the set of technologies you're talking about completely inappropriate; C/C++/Java apps communicating over raw TCP sockets or through a high performance middleware are the only way to get the necessary performance. Internet distribution has unpredictable delays.

Of course, if you're talking about the low-end of the market, where 'realtime' means the user won't get bored waiting for a response, as opposed to liveness of data, then there are many possible technologies. AJAX may be suitable, using either XML or JSON payload.

What type of data source do the quotes come from? Is it's a database, XML/JSON AJAX makes sense; if it's message-orientated middleware, then sockets are much better.

Do you need to have real-time updates, and is it acceptable for individual updates to get aggregated?

To start with, I'd suggest using DateTime.ParseExact or TryParseExact - it's not clear to me whether your sample is meant to be December 2nd or February 12th. Specifying the format may well remove your FormatException.

The next problem is working out which time zone you want to convert it with - are you saying that 11:58 is a local time in some time zone, or it's already a UTC time?

If it's a local time in the time zone of the code which is running this, you can use DateTimeStyles.AssumeLocal | DateTimeStyles.AdjustToUniversal to do it as part of parsing.
If it's already a universal time, use DateTimeStyles.AssumeUniversal
If it's a local time in a different time zone, you'll need to use TimeZoneInfo to perform the conversion.

Also, if it's a local time you'll need to consider two corner cases (assuming you're using a time zone which observes daylight saving time):

A local time may be skipped due to DST transitions, when the clocks go forward. So if the clocks skip from 1am to 2am, then 1:30am doesn't exist at all.
A local time may be ambiguous due to DST transitions, when the clocks go back. So if the clocks go back from 2am to 1am, then 1:30am occurs twice at different UTC times - which occurrence are you interested in?

You should decide how you want to handle these cases, and make sure they're covered in your unit tests.

Another option is to use my date and time library, Noda Time, which separates the concepts of "local date/time" and "date/time in a particular time zone" (and others) more explicitly.

Your label which contains the image is being replaced with label123 in the BorderLayout.CENTER position, which doesnt have any image attached. You could use:

label123.setIcon(ii);

If you want the 2 labels to be shown, you could place the text-based label123 in the SOUTH location:

jframe.add(label123, BorderLayout.SOUTH);

Note: Use JLabel instead of Label.

I have done a lot of looking around, and am seeing a lot about coding these things from scratch but little dealing with Swing implementation. I put my customer object into my map and then I would like for my JList to reflect the map's contents, but I don't know how to hook it up.

or use a MasterPage for each aspx page in that folder and put the following in the Page_Load

if (Request.UserHostAddress != "127.0.0.1" && !Request.UserHostAddress.StartsWith("172.16")) { Response.Redirect("http://www.kwiktrip.com", true); }

I used to be in the same situation, becoming known as the go-to guy. Then one day a PM said something to me that made me realize why I was always becoming that guy.

It's ok to say no sometimes.

Sometimes you need to push back on tasks and say, politely, no you can't do that or you can do that so long as this other task they also need is delayed or even handed off to another.

A task tracking system also helps with this. If you have a publicly available system then when people ask you to do something you can add it to the list, or have them add it. And then they can see what your task list is and where their task falls on it.

Also, only accept requests from your immediate manager. If the CEO comes down and asks you to do something, that's fine, but double check with your manager for confirmation. Often they can handball the task on or get the task pushed back up the chain.

So your nodes have a name: property and a children: array property.

Databases typically store trees in tables as

node-id, parent-id, value1, ..., valueN

(you can get certain advantages if you store depth-first visit order and depth-first return order; ask in comments if you need the details).

If you make a single query and get this data into JSON, you will have something like (for your illustration),

[{id: "0", parent: "-1", name: "A2"}, {id: "1", parent: "0", name: "A3"}, {id: "2", parent: "1", name: "A31"}, {id: "3", parent: "2", name: "A311"}, {id: "4", parent: "2", name: "A312"}]

You can convert this into {name: children:} format with the following code:

 // data is an array in the above format function toTree(data) { var childrenById = {}; // of the form id: [child-ids] var nodes = {}; // of the form id: {name: children: } var i, row; // first pass: build child arrays and initial node array for (i=0; i<data.length; i++) { row = data[i]; nodes[row.id] = {name: row.name, children: []}; if (row.parent == -1) { // assume -1 is used to mark the root's "parent" root = row.id; } else if (childrenById[row.parent] === undefined) { childrenById[row.parent] = [row.id]; } else { childrenById[row.parent].push(row.id); } } // second pass: build tree, using the awesome power of recursion! function expand(id) { if (childrenById[id] !== undefined) { for (var i=0; i < childrenById[id].length; i ++) { var childId = childrenById[id][i]; nodes[id].children.push(expand(childId)); } } return nodes[id]; } return expand(root); }

See http://jsfiddle.net/z6GPB/ for a working example.

36239903 0 What's the difference between Remove and Exclude when refactoring with PyCharm?

The official PyCharm docs explain Exclude when it comes to refactoring: One can, say, rename something with refactoring (Shift+F6), causing the Find window to pop up with a Preview. Within, it shows files which will be updated as a result of the refactor. One can right-click on a file or folder in this Preview and choose Remove or Exclude. What's the difference?

The accepted answer ignores a very important aspect: extended precision floating point. The CPU may be doing calculations with a bit-size that exceeds your storage size. This will particularly be true if you use float but can also be true of double and other floating point types.

To show the problem, the following assert may actually fail depending on how the compilation was done and how the chip behaves.

 void function( float a ) { float b = a / 0.12345; assert( b == (a/0.12345) ); }

Now, in this reduced example it will likely always pass, but there are many cases where it will not. Simply look at GCC Bug 323 and look at how many defects are marked as duplicates. This extended precision causes problems for many people, and it may also cause problems for you.

If you need a guarantee what you'll need to do is make a comparison function that takes two float parameters and guarantee that the function is never inlined (stored floats are not subject to extended precision). That is, you must ensure those floats are actually stored. There is also a GCC option called "store-float" I believe which forces storage, perhaps it can be used here on your individual function.

Here's an alternative using a ChartWrapper instead of a chart.

var opts = { "containerId": "chart_div", "dataTable": datatable, "chartType": "Table", "options": {"title": "Now you see the columns, now you don't!"} } var chartwrapper = new google.visualization.ChartWrapper(opts); // set the columns to show chartwrapper.setView({'columns': [0, 1, 4, 5]}); chartwrapper.draw();

If you use a ChartWrapper, you can easily add a function to change the hidden columns, or show all the columns. To show all the columns, pass null as the value of 'columns'. For instance, using jQuery,

$('button').click(function() { // use your preferred method to get an array of column indexes or null var columns = eval($(this).val()); chartwrapper.setView({'columns': columns}); chartwrapper.draw(); });

In your html,

<button value="[0, 1, 3]" >Hide columns</button> <button value="null">Expand All</button>

(Note: eval used for conciseness. Use what suits your code. It's beside the point.)

can you format your data in question. I am not sure whether I get youe point?

 CREATE TABLE #tt([name] VARCHAR(10),[date] DATE,skill INT,seconds INT, calls int ) INSERT INTO #tt SELECT 'bob','9/2/2016',706,12771,56 UNION all SELECT 'bob','9/2/2016',707,4061,16 UNION all SELECT 'bob','9/2/2016',708,2577,15 UNION all SELECT 'bob','9/2/2016',709,2156,6 SELECT * FROM ( SELECT t.name,t.date,c.* FROM #tt AS t CROSS APPLY(VALUES(LTRIM(t.skill)+'sec',t.seconds),(LTRIM(t.skill)+'calls',t.seconds)) c(t,v) ) AS A PIVOT(MAX(v) FOR t IN ([706sec],[706calls],[707sec],[707calls],[708sec],[708calls],[709sec],[709calls])) p

 name date 706sec 706calls 707sec 707calls 708sec 708calls 709sec 709calls ---------- ---------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- bob 2016-09-02 12771 12771 4061 4061 2577 2577 2156 2156

if the count of skill is not fix, you can use dynamic script：

 DECLARE @col VARCHAR(max),@sql VARCHAR(max) SELECT @col=ISNULL(@col+',[','[')+LTRIM(skill)+'sec],['+LTRIM(skill)+'calls]' FROM #tt GROUP BY skill SET @sql=' SELECT * FROM ( SELECT t.name,t.date,c.* FROM #tt AS t CROSS APPLY(VALUES(LTRIM(t.skill)+''sec'',t.seconds),(LTRIM(t.skill)+''calls'',t.seconds)) c(t,v) ) AS A PIVOT(MAX(v) FOR t IN ('+@col+')) p' EXEC (@sql)

41043440 0 Excel MDX linked server fails connection test

My first post after 2 years of learning to write SQL and using SQL Server, most of my questions have been answered researching on this website, however I cannot find the answer to my question below:

I am creating a new linked server, grabbing data from Excel using an MDX query in my SQL script. For example:

SELECT * into raw.example FROM openquery( Test1, 'MDX CODE/etc etc'

I clicked on my database > Server Objects > Linked Servers > New Linked Server >

Linker Server: TESTEXAMPLE Server Type: other data source Provider: Microsoft OLE DB Provider for Analysis Services 10.0 Product Name: Test1 Data Source: Name of server Provider String: Location: Catalog: OLAP

After I click "ok" to create this linked server this message comes up:

The linked server has been created but failed a connection test. Do you want to keep the linked server?

OLE DB provider 'MSOLAP' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode. (Microsoft SQL Server, Error: 7308)

I am not sure why it isn't connecting. Is it a server issue where I have to ask for permission to access it? Or do I somehow need to revert away from the provider being configured to run in a single-threaded apartment mode?

I am doing this on my local SQL Server Express Edition machine. Whereas before my script and OPENQUERY/MDX query worked on a remote desktop server etc.

I have looked at other posts but those solutions do not solve my problem.

It depends when you start from (0,0) or at a random location in the matrix.

If it is (0,0) ; use Depth First to go until the end of one branch then the others. Use Breadth First to iterate through all neigbouring nodes at a step. Check only down and right nodes.

If it is at a random location in the matrix, you need to trace all 4 neighbouring nodes.

It's because the file permissions are not the only protection you're encountering.

Those aren't just regular text files on a file system, procfs is a window into process internals and you have to get past both the file permissions plus whatever other protections are in place.

The maps show potentially dangerous information about memory usage and where executable code is located within the process space. If you look into ASLR, you'll see this was a method of preventing potential attackers from knowing where code was loaded and it wouldn't make sense to reveal it in a world-readable entry in procfs.

This protection was added way back in 2007:

This change implements a check using "ptrace_may_attach" before allowing access to read the maps contents. To control this protection, the new knob /proc/sys/kernel/maps_protect has been added, with corresponding updates to the procfs documentation.

Within ptrace_may_attach() (actually within one of the functions it calls) lies the following code:

if (((current->uid != task->euid) || (current->uid != task->suid) || (current->uid != task->uid) || (current->gid != task->egid) || (current->gid != task->sgid) || (current->gid != task->gid)) && !capable(CAP_SYS_PTRACE)) return -EPERM;

so that, unless you have the same real user/group ID, saved user/group ID and effective user/group ID (i.e., no sneaky setuid stuff) and they're the same as the user/group ID that owns the process, you're not allowed to see inside that "file" (unless your process has the CAP_SYS_PTRACE capability of course).

7649018 0 Parser replace pattern

I have problems with pattern. I need to process some text for example:

<div>{text1}</div><span>{text2}</span>

After the process I need to get in place of {text1} and {text2} some words from dictionary. I'm preparing ui interface for diffrent languages. This is in PHP. For now I have something like this but this doesn't work:

function translate_callback($matches) { global $dict; print_r($matches); return 'replacement'; } function translate($input) { return preg_replace_callback('/(\{.+\})/', 'translate_callback', $input); } echo translate('<div>{bodynum}</div><span>{innernum}</span>');

This is test scenarion but I can't find the way to define pattern because this one in code match

{bodynum}</div><span>{innernum}

but I want pattern that will match

{bodynum} and then {innernum}

Can somebody help me with this. Thanks.

The Solution:

To match any character between { and }, but don't be greedy - match the shortest string which ends with } (the ? stops + being greedy).

So the pattern now looks like: '/{(.+?)}/' and is exacly what I want.

Looks like you can't just pass touches in and have it respond to them :(

You would have to use the [UIScrollView setContentOffset:animated:] method to move the scrollview yourself.

A better way of intercepting the touches might be to put a view in front of the scrollview - grab any touches you want to listen to and then pass it to the next responder in the chain.

You would make a subclass of UIView that overrode the touch handling methods, something like :

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { if (scrollViewShouldGetThisTouch) [self.nextResponder touchesBegan:touches withEvent:event]; }

and just make this view have the same frame as your scrollview but be infront of it in the ui (transparent of course!).

You could subclass UIScrollView - though this might result in odd errors if Apple ever change the implementation of a UIScrollView. I'd choose the other option!

I solved my own problem with the following steps: 1. Deleted MSCOMCTL.OCX from \Windows\Syswow64 2. Opened the Access form that was giving me a problem, and Access reinstalled MSCOMCTL.OCX automatically. 3. Opened a command window with the "Run As Administrator" option 4. Navigated to \Windows\Syswow64 5. Ran "regsvr32 /u MSCOMCTL.OCX" 6. Ran "regsvr32 MSCOMCTL.OCX" 7. Reopened Access and it worked! Note: You will need to do this in System32, NOT Syswow64 for 64-bit office. Dumb naming standard, I know.

12008953 0 mysql - how to get all differences from one table to another (huge amount of rows ~ 500k)

In the

`synchro_newitems`

table I have all new items (from external source) ~ about 500k rows. It has one column:

`new_ids`

In the

`synchro_olditems`

table I have all current items (also from external source) ~ about 500k rows. It has one column:

`old_ids`

I must get only the new items from synchro_newitems:

(NEW ITEMS) = synchro_newitems (-) synchro_olditems

I tried do that by insert the differences to the 3rd table:

INSERT INTO `synchro_diff` (`id`) SELECT DISTINCT new_ids FROM synchro_newitems LEFT JOIN synchro_olditems ON synchro_newitems.new_ids = synchro_olditems.old_ids WHERE synchro_olditems.old_ids IS NULL

(similarly with "NOT IN")

It's works for small amount of rows. But fails when there are 500 000 rows to compare.

I've tried simple:

DELETE FROM synchro_newitems WHERE exists(SELECT * FROM synchro_olditems)

But it dosent work.. Do you know some smart method to do that?

You only have to change the client.

Change its Naming.lookup() string, from "localhost" to the server's hostname or IP address. The server's Naming string in the bind() or rebind() call does not change from "localhost", because the server and its Registry are always on the same host.

If you are using Registry instead of Naming, again you only have to change the client's LocateRegistry.getRegistry() call.

Could be your result is already JSON parsed the

 function getLocation(){ var name = $("#username").val(); console.log('getLocation()'); if(name != ''){ $.ajax({ type: 'GET', url: '../../' + name, async: true, success:function(data){ var marker = new L.marker(data.location); marker.addTo(map); $("#username").val(''); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert('Not found'); } }); } }

or if you obtain an array

 function getLocation(){ var name = $("#username").val(); console.log('getLocation()'); if(name != ''){ $.ajax({ type: 'GET', url: '../../' + name, async: true, success:function(data){ var marker = new L.marker(data[0].location); marker.addTo(map); $("#username").val(''); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert('Not found'); } }); }

36629637 0 how to fetch records equal to pageSize while using queryForCursor in SolrTemplate

I want to fetch records from solr using cursors as I have large resultset size. I m using SolrTemplate.queryForCursor() method by passing query object to this. But the resultCursor which is of type Cursor has all data in it. I want to stop reading from cursor when my pageSize is hit.

Criteria query = new Criteria("UserName").is ("abc"); query.setRows(10); // As i want to have fetch 10 records at a time Cursor<T> resultCusrsor = solrTemplate.queryForCursor(query,Entity.class); while(resultCursor.hasNext() ){ System.out.println( "Result : " + resultCusrsor.next()); }

The while loop here keeps printing all records by fetching 10 at a time. If my pagesize is 100, I want to fetch 10 records 10 times using cursor, but how do I stop at 100th record?

There is no need that an application defines a window handle when using OpenClipboard. So you have to be aware that there are enough chances that you will never get a result.
If it is a child window that owns the clipboard you may walk back the stack of windows always using GetParent until there is no longer a parent.

BTW: The function I mention here are the WinApi functions...

The border is going to push the text to the right as it should. Have you tried making the text shift to the left with a negative margin (margin-left: -2px) when the hover occurs if possible? Or adding a bit of padding (2px) in this case when not on hover and taking it away on hover.

The reason I was unable to see the Configure and Associate menu options was due to the selected perspective. Code Composer 5 uses TI's default CCS Edit perspective which hides the expected menu options. If you change to the default Eclipse C/C++ perspective then the menu option shows up and configuration of the project to use SonarQube can be completed.

Here is my solution, hope will help.. :D

in your model.. i copy paste code bellow but i change a little..

function login ($username, $password) { $this->db->where('username' , $username); $this->db->where('password', $password); $query = $this->db->get('users'); if ($query->result())//if any record { $rows = $query->row(); $data = array( 'user_name' => $rows->username, 'logged_in' => TRUE, 'validated' => true ); $this->session->set_userdata($data); return true; } else { return false; } }

delete your session_start() in controller,, and then in your application/config/autoload.php

in this $autoload['libraries'] = array(); => add session like this $autoload['libraries'] = array('session');

Thankyou.. :D

If you want to still break from if, you can use while(true)

Ex.

$count = 0; if($a==$b){ while(true){ if($b==$c){ $count = $count + 3; break; // By this break you will be going out of while loop and execute remaining code of $count++. } $count = $count + 5; // break; } $count++; }

Also you can use switch and default.

$count = 0; if($a==$b){ switch(true){ default: if($b==$c){ $count = $count + 3; break; // By this break you will be going out of switch and execute remaining code of $count++. } $count = $count + 5; // } $count++; }

Django's ORM will have trouble working with this table unless you add a unique primary key column.

If you do add a primary key, then it would be trivial to write a method to query for a given product ID and return a list of the values corresponding to that product ID. Something like:

def names_for(product_id): return [row.namestring for row in ProductName.objects.filter(product_id=product_id)]

This function could also be a custom manager method, or a method on your Product model, or whatever makes most sense to you.

EDIT: Assuming you have a Product model that the product_id in this table refers to, and the only use you'll have for this table is to look up these names for a given product, your other option is to leave this table out of the ORM altogether, and just write a method on Product that uses raw SQL and cursor.execute to fetch the names for that product. This is nice and clean and doesn't require adding a unique PK to the table. The main thing you lose is the ability to administer this table via Django modelforms or the admin.

>>> [id(x) for x in a] [4454962120, 4454962120, 4454962120]

While this:

>>> b = [[], [], []]

creates three different lists:

>>> [id(x) for x in b] >>> [4454963720, 4455011592, 4454853448]

You can create a large list containing different sub-lists with a list comprehension:

>>> size = 100 >>> long_list = [[] for x in range(size)]

Now appending to the first sub-list:

>>> long_list[0].append(10) >>> long_list[:10]

changes only the first sub-list:

>>> long_list[:10] [[10], [], [], [], [], [], [], [], [], []]

3337441 0 MySQL - Searching in a multiple value field

In my database table I have the following fields:

Table Supplier:

id
name
vehicles

A supplier can have multiple vehicles. The field 'vehicles' will store multiple values. At the moment I am delimiting the values on a 'pipe' symbol, although this can be changed to a comma if need be.

On my front-end form I have a checkbox list - a user can select multiple vehicles. The back end script needs to do a search and bring back all suppliers that contain any of the specified vehicle id's.

So in other words we are searching with multiple values in a multiple value field.

The checkbox list name is vehicle_type[] and will end up in the $_POST array as (for example):

Array ( [0] => 1 [1] => 4 [2] => 6 )

Is this possible to do? I could obviously do this using a join table but ideally I would like to do it this way. I am using PHP as my scripting language if that helps.

This is, at it has been stated, not the optimal way to load resources, but if you absolutely must have a java.io.File reference, then try following:

 URL url = null; try { URL baseUrl = YourClass.class.getResource("."); if (baseUrl != null) { url = new URL(baseUrl, "yourfilename.ext"); } else { url = YourClass.class.getResource("yourfilename.ext"); } } catch (MalformedURLException e) { // Do something appropriate }

This gives you a java.net.URL and it can be used in a java.io.File constructor.

11098489 0

Something that you could do is to send 2 parameters to the url :

fileName = the filename
fileContent = content of file encoded in base64

In your asp file, just get the 2 parameters content, make a base 64 decode, and write it in a file named as the filename parameter ...

The context of a process (psw, state of registers,pc...) is saved in the PCB of the process, in the kernel space of memory, not in the stack. Yes, there is one stack for each user process and more, one stack for each thread in the user space memory. In the kernel, the data structures are shared by the multiples codes of the function in the kernel. The stack is used for the call of procedure and for the local variables, not for saving the context.

At the Servers side you can just check for:

if(isset($_POST['name'])) { } // only send the mail if this is true.

There are also many client side solutions. You could also write your own using Javascript. You will have to still include the checks on the server-side tho since "client-side security does not work".. The user could just disable Javascript and submit the form without the checks running.

Here is an example for a JS library that does form validation:

I found it by googling for javascript form validation

So I think I figured it out. It boils down to a chicken or egg scenario. When you register a generic class via the RegisterGeneric method, Autofac will not automatically register the closed types unless it detects them somewhere in your object graph as a dependency.

Ctor 1 doesn't trigger closed generics to be registered:

 public MessageHandlerFactory(IEnumerable<IMessageHandler> handlers){ }

Ctor 2 does trigger closed generics to be registered:

 public MessageHandlerFactory(IEnumerable<IMessageHandler> handlers, MessageHandler<ComplexMessage> complexHandler, MessageHandler<SimpleMessage> simpleHandler ){}

Once I manually registered the closed generics using the code below, Autofac began injecting them as part of the IEnumerable<IMessageHandler> dependency seen on Ctor 1

builder.RegisterType(typeof(MessageHandler<ComplexMessage>)).AsImplementedInterfaces(); builder.RegisterType(typeof(MessageHandler<SimpleMessage>)).AsImplementedInterfaces();

I use tooltipsy, this is an EXCELLENT tooltip program. You can set it to do pretty much anything you want. If you want custom CSS, okay, if you want to set your own show and hide events, okay, you can change what the tooltip aligns to, the delay until it shows, you can do whatever you want. Tootipsy is the best one I ever used. (I had to make a little modification to it to get it to use HTML in the tooltips though, but it's a very simple change)

33077123 0 Floating Action Button diasappears under SECOND Snackbar

I'm using a CoordinatorLayout to keep my Floating Action Button above the Snackbar, which works great. ...But only for the first Snackbar. When a second one is created, while the first one is still there, the FAB slides under it.

I'm using this in a RecyclerView in which I can remove items. When an item is removed, a "Undo" Snackbar appears. So when you delete some items one after another, the visible Snackbar is replaced by a new one (which causes the FAB behaviour)

Do you know a solution to keep the FAB above new Snackbars?

<?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:fab="http://schemas.android.com/tools" android:id="@+id/coordinator_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:backgroundTint="@color/background_grey" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <include android:id="@+id/toolbar" layout="@layout/toolbar" /> <android.support.v7.widget.RecyclerView android:id="@+id/recyclerView" android:layout_width="match_parent" android:layout_height="match_parent" android:scrollbars="vertical" /> </LinearLayout> <android.support.design.widget.FloatingActionButton android:id="@+id/fab" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="bottom|end" android:layout_marginBottom="16dp" android:layout_marginEnd="16dp" android:layout_marginRight="16dp" android:elevation="6dp" android:src="@drawable/ic_add_white_36dp" app:borderWidth="0dp" app:fabSize="normal" app:pressedTranslationZ="10dp" app:rippleColor="@color/abc_primary_text_material_dark" /> </android.support.design.widget.CoordinatorLayout>

you could try something like

B.x.where(B.x.str.contains(A.x), B.index, axis=index) #this would give you the ones that don't match B.x.where(B.x.str.match(A.x, as_indexer=True), B.index, axis=index) #this would also give you the one's that don't match. You could see if you can use the "^" operator used for regex to get the ones that match.

You could also maybe try

np.where(B.x.str.contains(A.x), B.index, np.nan)

also you can try:

matchingmask = B[B.x.str.contains(A.x)] matchingframe = B.ix[matchingmask.index] #or matchingcolumn = B.ix[matchingmask.index].x #or matchingindex = B.ix[matchingmask.index].index

All of these assume you have the same index on both frames (I think)

You are using static method for custom sorting, so you can set some static properties in this class before usort

class Catalogs_model{ public static $usort_criteria = array(); public static function multi_compare($a,$b){ foreach(self::$usort_criteria as $what => $order){ if($a[$what] == $b[$what]){ continue; } return (($order == 'desc')?-1:1) * strcmp($a[$what], $b[$what]); } return 0; } } Catalogs_model::$usort_criteria = array( 'con' => 'asc', 'title' => 'asc' ); usort($arrCatalog, array('Catalogs_model', 'multi_compare'));

of course it needs some tweaking , because now it only sorts strings.

exec 3>&1 1>>${LOG_FILE} 2>&1

would send stdout and stderr output into the log file, but would also leave you with fd 3 connected to the console, so you can do

echo "Some console message" 1>&3

to write a message just to the console, or

echo "Some console and log file message" | tee /dev/fd/3

to write a message to both the console and the log file - tee sends its output to both its own fd 1 (which here is the LOG_FILE) and the file you told it to write to (which here is fd 3, i.e. the console).

Example:

exec 3>&1 1>>${LOG_FILE} 2>&1 echo "This is stdout" echo "This is stderr" 1>&2 echo "This is the console (fd 3)" 1>&3 echo "This is both the log and the console" | tee /dev/fd/3

would print

This is the console (fd 3) This is both the log and the console

on the console and put

This is stdout This is stderr This is both the log and the console

into the log file.

Let’s look at three common reasons for writing inner functions.

1. Closures and Factory Functions

The value in the enclosing scope is remembered even when the variable goes out of scope or the function itself is removed from the current namespace.

def print_msg(msg): """This is the outer enclosing function""" def printer(): """This is the nested function""" print(msg) return printer # this got changed

Now let's try calling this function.

>>> another = print_msg("Hello") >>> another() Hello

That's unusual. The print_msg() function was called with the string "Hello" and the returned function was bound to the name another. On calling another(), the message was still remembered although we had already finished executing the print_msg() function. This technique by which some data ("Hello") gets attached to the code is called closure in Python.

When To Use Closures?

So what are closures good for? Closures can avoid the use of global values and provides some form of data hiding. It can also provide an object oriented solution to the problem. When there are few methods (one method in most cases) to be implemented in a class, closures can provide an alternate and more elegant solutions. Reference

2. Encapsulation :

General concept of encapsulation is to hide and protect inner world from Outer one, Here inner functions can be accessed only inside the outer one and are protected from anything happening outside of the function.

3. Keepin’ it DRY

Perhaps you have a giant function that performs the same chunk of code in numerous places. For example, you might write a function which processes a file, and you want to accept either an open file object or a file name:

def process(file_name): def do_stuff(file_process): for line in file_process: print(line) if isinstance(file_name, str): with open(file_name, 'r') as f: do_stuff(f) else: do_stuff(file_name)

I am trying to redirect to different page after current form has been submitted but as it turns out, using window.location am diverted to new page very quickly and seems like my current form is not at all submitted.

Here the function that am using.

function updateImportJobTypeSettings() { var importJob = document.getElementById("jobtype").value; var parser = document.getElementById("selectparser"); var parserValue = parser.options[parser.selectedIndex].value; document.importJobManagmentForm.action="/admin/ImportJobManagment.jsp"; document.importJobManagmentForm.requestAction.value="updateImportJobSettings"; document.importJobManagmentForm.ImportJobParser.value=parserValue; document.importJobManagmentForm.ImportJobManagmentType.value=importJob; document.importJobManagmentForm.DivHidden.value="visible"; document.importJobManagmentForm.submit(); window.location = "/admin/ImportJobManagmentList.jsp" }

My goal is that after ImportManagment.jsp page is submitted, I want to come back to ImportJobManagmentList.jsp page to see all data that were submitted to ImportJobManagment.jsp

Think to note here is that if I put debugger on then I do see that new job is created on JobList but if I go and try to update it, again new job is created rather than doing an update to the previous job.

I don't understand what exactly you need,

But it seems that you mixed types INT and DATE.

So if your in_date field has type DATE

select cust_no, cust_name, sum(bvtotal) as Amount from sales_history_header where cust_no is not null and number is not null and bvtotal > 1000 and in_date < DATE('2014-01-01') group by cust_no,cust_name order by sum(bvtotal) desc;

If your in_date field has type TIMESTAMP

select cust_no, cust_name, sum(bvtotal) as Amount from sales_history_header where cust_no is not null and number is not null and bvtotal > 1000 and in_date < TIMESTAMP('2014-01-01 00:00:00') group by cust_no,cust_name order by sum(bvtotal) desc;

@Entity public class MyEntity implements Serializable { private Long id; @Id @GeneratedValue(strategy = GenerationType.AUTO) public Long getId() { return id; } public void setId(Long id) { this.id = id; } }

This generally works fine. But now and then when trying to persist such an entity, I get this:

The underlying MySQL error is:

SQL Error: 1305, SQLState: 42000

My problem is that this system worked for months without any problem. Only recently I discovered the error described above. Do you have any ideas what could have caused this problem? What does Hibernate look for and doesn't find?

this code looks correct, are you sure the crash isn't somewhere else?

EDIT: as noted in the comments, NSString being immutable won't cause the copy to allocate a new object. I've edited the answer for the mutable case, just in case someone stumbles into this later and doesn't read the whole thing. Now back with our regular programming.

Don't know if this might be the problem, but note that, if you were using a mutable object like NSMutableString, with copy you would not increment the retain count, you would effectively create a new object, so what would happen:

NSMutableString* newString = [[NSMutableString alloc] init..]; // allocate a new mutable string self.originalString=newString; // this will create yet another string object // so at this point you have 2 string objects. [newString relase]; //this will in fact dealloc the first object // so now you have a new object stored in originalString, but the object pointed // to by newString is no longer in memory. // if you try to use newString here instead of self.originalString, // it can indeed crash. // after you release something, it's a good idea to set it to nil to // avoid that kind of thing newString = nil;

enter image description here I have a class that has a private member of another class, and which that class is an ObserveableCollection of another class.. and this is the class I need info from, that has private members that I want to databind.

_controller = new DtvGsisDataParser.AppController(); foreach (var item in _controller.Games) { string hometri = item.HomeTri; string awaytri = item.AwayTri; ... etc etc }

how can i get it so that if a hometri and awaytri are equal to what i'm looking for... i can get the other instances of that class? for example

if item.HomeTri==what i want && item.AwayTri==what i want then bind item._homeScore to a certain label then bind item.awayAScore to a certain label.

i know what i'm asking for is kinda complex.. but i'm kinda desperate here and would appreciate any help. this databinding is very new to me and i'm having trouble grasping it. is this even possible? the more i research the more i dont think so.. but i'm hoping i'm not. thanks for any help

for($i = 0; $i < 5; $i++) { $data[i] = $staffID[$i].','.$staffname[$i].','.$ismanager[$i].','.$remark[$i]; }

Next I go to write csv file.

$file_format = "staffreport.csv"; $file = fopen($file_format,"w"); foreach($data as $line) { $replace = str_replace(",","|", $line); fputcsv($file, array($replace)); echo $replace.'<br />'; } fclose($file);

output (echo $replace)

0005|Siti|Y|Only one manager allowed!
In CSV file (staffreport.csv)
0001|Ali|N|OK
0002|Abu|N|OK
0003|Ahmad|N|OK
"0004|Siti|Y|Only one manager allowed!"
"0005|Raju|Y|Only one manager allowed!"
Why my csv file have double quote("")? How do I solve it?

you can modify the sass variables that set the breakpoints that define the media queries, just set them to extreme values so that they do not trigger. This will provide very poor ux on devices with small displays. Another solution would be to match all of the grids, so if you have a .large-12 then add .small-12 .large-12 for each instance.

Here are the defaults pulled from the zurb foundation docs:

$small-range: (0em, 40em); $medium-range: (40.063em, 64em); $large-range: (64.063em, 90em); $xlarge-range: (90.063em, 120em); $xxlarge-range: (120.063em); $screen: "only screen" !default; $landscape: "#{$screen} and (orientation: landscape)" !default; $portrait: "#{$screen} and (orientation: portrait)" !default; $small-up: $screen !default; $small-only: "#{$screen} and (max-width: #{upper-bound($small-range)})" !default; $medium-up: "#{$screen} and (min-width:#{lower-bound($medium-range)})" !default; $medium-only: "#{$screen} and (min-width:#{lower-bound($medium-range)}) and (max-width:#{upper-bound($medium-range)})" !default; $large-up: "#{$screen} and (min-width:#{lower-bound($large-range)})" !default; $large-only: "#{$screen} and (min-width:#{lower-bound($large-range)}) and (max-width:#{upper-bound($large-range)})" !default; $xlarge-up: "#{$screen} and (min-width:#{lower-bound($xlarge-range)})" !default; $xlarge-only: "#{$screen} and (min-width:#{lower-bound($xlarge-range)}) and (max-width:#{upper-bound($xlarge-range)})" !default; $xxlarge-up: "#{$screen} and (min-width:#{lower-bound($xxlarge-range)})" !default; $xxlarge-only: "#{$screen} and (min-width:#{lower-bound($xxlarge-range)}) and (max-width:#{upper-bound($xxlarge-range)})" !default;

It seems that whenever you talk about anything J2EE related - there are always a whole bunch of assumptions behind the scenes - which people assume one way or the other - which then leads to confusion. (I probably could have made the question clearer too.)

Assuming (a) we want to use container managed transactions in a strict sense through the EJB specification then

Session facades are a good idea - because they abstract away the low-level database transactions to be able to provide higher level application transaction management.

Assuming (b) that you mean the general architectural concept of the session façade - then

Decoupling services and consumers and providing a friendly interface over the top of this is a good idea. Computer science has solved lots of problems by 'adding an additional layer of indirection'.

Rod Johnson writes "SLSBs with remote interfaces provide a very good solution for distributed applications built over RMI. However, this is a minority requirement. Experience has shown that we don't want to use distributed architecture unless forced to by requirements. We can still service remote clients if necessary by implementing a remoting façade on top of a good co-located object model." (Johnson, R "J2EE Development without EJB" p119.)

Assuming (c) that you consider the EJB specification (and in particular the session façade component) to be a blight on the landscape of good design then:

Rod Johnson writes "In general, there are not many reasons you would use a local SLSB at all in a Spring application, as Spring provides more capable declarative transaction management than EJB, and CMT is normally the main motivation for using local SLSBs. So you might not need th EJB layer at all. " http://forum.springframework.org/showthread.php?t=18155

In an environment where performance and scalability of the web server are the primary concerns - and cost is an issue - then the session facade architecture looks less attractive - it can be simpler to talk directly to the datbase (although this is more about tiering.)

Reading your problem description "each box contain 10 piece of numbered paper (1 - 10) but there is a number the same in all 3 boxes" I take it that:

each box has exactly ten pieces of paper
each piece of paper has a number from 1 to 10 on it
there is only one number that appears in all three boxes
(hence, other numbers may appear more than once)

Like here, where the number '8' is the only one to appear in all three boxes.

 int[] a = new int[] { 3, 2, 7, 5, 8, 2, 10, 6, 9, 7, 3 }; int[] b = new int[] { 1, 4, 8, 7, 5, 1, 3, 2, 2, 4, 1 }; int[] c = new int[] { 8, 4, 1, 6, 10, 9, 6, 4, 9, 6, 4 };

Is that your problem?

Then you wrote: "How to find that repeated number in java with an efficient/fastest way possible?"

Now how efficient/fast do you want to be? Are you talking about O(n) efficient (even though the boxes are unsorted), like here (slightly obfuscated to confuse you a bit):

 int s = 0; int t = 0; int u = 0; for (int i = 0; i < 10; i++) { s |= 1 << a[i]; t |= 1 << b[i]; u |= 1 << c[i]; } System.out.println( Integer.numberOfTrailingZeros( s & t & u ) );

; )

Somehow I'm not sure your teacher will think you came up with that answer : )

23111646 0 get customer payment ids from CIM

How can I get customer payment method ids from AuthorizeNetCIM_Response object?

There's a method in AuthorizeNetCIM_Response which is supposed to return payment method ids

public function getCustomerPaymentProfileIds() { $ids = (array)$this->xml->customerPaymentProfileIdList; return $ids["numericString"]; }

but calling this function results in error

Notice: Undefined index: numericString

The response object outputs as:

AuthorizeNet_AuthorizeNetCIMResponse Object ( [xml] => SimpleXMLElement Object ( [messages] => SimpleXMLElement Object ( [resultCode] => Ok [message] => SimpleXMLElement Object ( [code] => I00001 [text] => Successful. ) ) [profile] => SimpleXMLElement Object ( [merchantCustomerId] => 10 [email] => user@nine.com [customerProfileId] => 25441529 [paymentProfiles] => Array ( [0] => SimpleXMLElement Object ( [billTo] => SimpleXMLElement Object ( [firstName] => [lastName] => [address] => [city] => [zip] => [country] => [phoneNumber] => ) [customerPaymentProfileId] => 23298664 [payment] => SimpleXMLElement Object ( [creditCard] => SimpleXMLElement Object ( [cardNumber] => XXXX2224 [expirationDate] => XXXX ) ) ) [1] => SimpleXMLElement Object ( [customerType] => individual [billTo] => SimpleXMLElement Object ( [firstName] => Test [lastName] => Individual [company] => SimpleXMLElement Object ( ) [address] => [city] => [state] => [zip] => [country] => [phoneNumber] => SimpleXMLElement Object ( ) [faxNumber] => SimpleXMLElement Object ( ) ) [customerPaymentProfileId] => 23299421 [payment] => SimpleXMLElement Object ( [creditCard] => SimpleXMLElement Object ( [cardNumber] => XXXX0027 [expirationDate] => XXXX ) ) ) ) ) )

and I supposed to get the array of paymentProfiles as

$response->xml->profile->paymentProfiles;

but it only returning the first element of paymentProfiles not an array.

28762230 0 Elasticsearch wont apply not_analyzed into my mapping

When I try to apply "not_analyzed" into my ES mapping it doesnt work.

I am using this package for ES in Laravel - Elasticquent

My mapping looks like:

'ad_title' => [ 'type' => 'string', 'analyzer' => 'standard' ], 'ad_type' => [ 'type' => 'integer', 'index' => 'not_analyzed' ], 'ad_type' => [ 'type' => 'integer', 'index' => 'not_analyzed' ], 'ad_state' => [ 'type' => 'integer', 'index' => 'not_analyzed' ],

Afterwards I do an API get call to view the mapping and it will output:

"testindex": { "mappings": { "ad_ad": { "properties": { "ad_city": { "type": "integer" }, "ad_id": { "type": "long" }, "ad_state": { "type": "integer" }, "ad_title": { "type": "string", "analyzer": "standard" }, "ad_type": { "type": "integer" },

Note that not_analyzed is missing. I cant see any errors/warnings in my logs either.

NB: Not tested.

By the way, you might want to use camelCase on function names.

You must have the mime_magic extension on. Check your php.ini and look in phpinfo(). By the way this function has been deprecated as the PECL extension Fileinfo provides the same functionality (and more) in a much cleaner way.

Windows users must include the bundled php_fileinfo.dll DLL file in php.ini to enable this extension.

The libmagic library is bundled with PHP, but includes PHP specific changes. A patch against libmagic named libmagic.patch is maintained and may be found within the PHP fileinfo extensions source.

It really depends on how much this format might change over time and what you want to rely on as constant. If you want to assume that your html will always start with <div class="plugin-block"> and the text you want will always be on a line after an h3, you can do something like this:

$pattern = '/plugin-block(?:\n|.)*?<\/h3>\s*(.+)/'; preg_match($pattern, $html, $matches); echo $matches[1]; //**Intergrate Sailthru API functionality into your WordPress blog.**

11282594 0 What options do I have for storing information on Windows? How should I read this information?

what options I have for storing information on Windows?

I was thinking of creating a file or working with the registry but the file could get rather annoying to handle if it gets too big and the registry is a bit too easily accessible by the user.

I don't expect there to be more than a max of 100 entries and they would look something like this.

John Banana

Marcus Apple

etc.

I realize this wouldn't produce a too big file but I dont want to parse it everytime I need the information. I was thinking of reading the information into the application on startup but wouldn't that create performance issues? Or perhaps it's so little it wouldn't matter except for older computers? Are there any other options? Perhaps I could encrypt the information and put it in the registry? Is the registry suitable for putting multiple entries such as this?

Note that when I program I sometimes go a bit too overboard when it comes to making things efficient. Excuse my ignorance.

In your no-arg constructor, the line

 this(2.5, 1, 1000);

explicitly means "call another constructor for the same class as the current constructor, but which takes these arguments".

So that's why adding the other constructor fixes the problem. The order in which you pass the arguments needs to match the order in which the parameters appear on that constructor, that constructor's parameter list defines the order you need to put the arguments in when calling it.

The relationship between these two constructors is that they are chained. The one with the 3 arguments is the primary constructor, the other calls the primary constructor with default values. Designing constructors in this way helps to initialize your objects consistently, because a single primary constructor always gets called. (For instance, the loanDate instance field gets set regardless of which constructor you call.)

Description

You need no DataAnnotation Attribute to do that. In Codefirst you can do the following. The Entity Framework will generate the table you described for you.

Sample

Account { public int Id; } Job { public int Id; public virtual Account Account; } Practice { public int Id; public virtual Account Account; public string Name; }

If you want also a ìnt column (AccountId) in your Job / Practice Entity you can do this using the ModelBuilder. The Entity Framwork creates only one foreign key column, like you want.

protected override void OnModelCreating(DbModelBuilder modelBuilder) { modelBuilder.Entity<Job>.HasRequired(x => x.Account).WithMany().HasForeignKey(x => x.Accountid); // }

enter image description here

 <h2>Category : Throusers</h2> <h3>Sizes</h3> <ul data-bind="foreach: products"> <li> <input type="checkbox" data-bind="value: size.id" /> <label data-bind="text: size.name"></label> </li> </ul> <h3>Colors</h3> <ul data-bind="foreach: products"> <li> <input type="checkbox" data-bind="value: color.id" /> <label data-bind=" text: color.name"></label> </li> </ul> <h3>Products</h3> <ul data-bind="foreach: products"> <li> <label data-bind="text: name"></label> - <label data-bind="text: size.name"></label>- <label data-bind="text: color.name"></label> </li> </ul> <script type="text/javascript"> function Color(id, name) { return { id: ko.observable(id), name: ko.observable(name) }; }; function Size(id, name) { return { id: ko.observable(id), name: ko.observable(name) }; } function Product(id,name, size, color) { return { id: ko.observable(), name: ko.observable(name), size: size, color: color }; }; var CategoryViewModel = { id: ko.observable(1), name: ko.observable("Throusers"), products: ko.observableArray([ new Product(1,"Levi's 501", new Size(1, "30-32"), new Color(1, "Red")), new Product(2,"Colins 308", new Size(2, "32-34"), new Color(2, "Black")), new Product(3,"Levi's 507", new Size(1, "30-32"), new Color(3, "Blue")) ]) }; ko.applyBindings(CategoryViewModel); </script>

And now,

I wanna this: duplicated Sizes and colors should not list.
When I select a color from colors, selected color products should list and others should be disabled

If model is wrong?

Have you tried to add a ToList() statement to the where statement?

query = query.Where(x => x.GetType() == typeof(T)).ToList();

As I recall the result of the Where statement is a too generic collection and therefore it needs to be cast first.

Since I see that you're using an AddRange, it could also need to be converted to an array, use the ToArray() statement instead of the ToList() statement if the first doesn't work. I'm not sure if you can provide a List to an AddRange() statement.

I think this would depend on the method you used to do the URL rewriting.

Using IIS - Refer to this previous post on how to extract the full URL: get current url of the page (used URL Rewrite)
Using 404 - This is how I've done it in the past and the only way to access the raw URL is to check the querystring. The 404 URL will look something like this:
```
https://website.com/rewrite.asp?404;http://website.com/images/gal/boxes-pic004.asp 
```

To get the URL, I use something like this:

 Function getURL() Dim sTemp sTemp = Request.Querystring ' the next line removes the HTTP status code that IIS sends, in the form "404;" or "403;" or whatever, depending on the captured error sTemp = Right(sTemp, len(sTemp) - 4) ' the next two lines remove both types of server names that IIS includes in the querystring sTemp = replace(sTemp, "http://" & Request.ServerVariables("HTTP_HOST") & ":80/", "") sTemp = replace(sTemp, "http://" & Request.ServerVariables("HTTP_HOST") & "/", "") sTemp = replace(sTemp, "https://" & Request.ServerVariables("HTTP_HOST") & "/", "") sTemp = replace(sTemp, "https://" & Request.ServerVariables("HTTP_HOST") & ":443/", "") ' the next bit of code will force our array to have at least 1 element getURL = sTemp End Function

This will get you the full raw URL, you can then extract the part you need by using simple split like:

 tmpArr = Split(getURL(),"/") strScriptName = tmpArr(UBound(tmpArr))

The strScriptName variable will then return "boxes-pic004.asp".

Hope this helps.

Well... Former internet explorer versions had a mistake in their box model: the w3c box model takes width without padding and border, and the IE model took it including them. I have examined the page in a a new IE8 in windows 7, and I've only noticed that the border of the tabs were not rounded and they were not connected to the box. The corner can be done with images.

Sorry.

37474024 0 Ruby win32ole Gem with OLE error 800A004C (Path Not Found) for size method

I have a colossal directory on my hard-drive and I wanted to gather some stats so I began writing a script. To speed things up massively I used Windows OLE but I've come across an interesting issue where the the ar2 OLE object has a method called size but calling it gives me error 800A004C or "Path Not Found". I have also tested on other directories and the below code works perfectly fine.

I have used the method ole_methods and double checked the casing on size. The OLE method in Ruby definitely exists but no dice on getting it to succeed.

Why is Windows OLE throwing this error when it should know the folder exists and compute the overall size of the folder structure recursively?

require 'win32ole' def getFileCount(dir) size = dir.Files.count sub_folders = dir.SubFolders unless sub_folders == 0 sub_folders.each do |sub| size += getFileCount(sub) end end size end AR2_NAME = ARGV[0] FSO = WIN32OLE.new("Scripting.FileSystemObject") ar2 = FSO.GetFolder(AR2_NAME) ar2_file_count = getFileCount(ar2) puts "Stats for #{ar2.path}.\n\n" puts "Total file count: #{ar2_file_count}." puts "Total size: #{ar2.size}."

What do you mean by images in hard drive.Are you saying that you have kept your images in your bundle in iphone app.If so then you can make array of those images like this....

NSMutableArray *imageArray; imageArray=[[NSMutableArray alloc]initWithObjects:@"001.jpg",@"002.jpg",@"003.jpg",@"004.jpg",nil];

And then can access your images by this array;

Or if you simply want to show a single image from the bundle you can do this way

UIImageView *creditCardImageView=[[UIImageView alloc]initWithFrame:CGRectMake(10, 16, 302, 77)]; creditCardImageView.image=[UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"CreditCard_2RowTable" ofType:@"png"]]; [self.view addSubview:creditCardImageView];

This will help you.

Tight loop with high priority thread is not a good idea...when the print hello is just looping without doing anything, Introduce switchtothread/yield after certain loops and sleep zero after a higher loop count. This will give other threads on the system oppurtinity to execute Eventually wait on a event handle when there is no work.

12389454 0 NSString Somehow turn in to an "__NSArrayI" object

i am receiving response from my server, it looks like this :

2012-09-12 16:29:11.690 WhatIsIt[1763:707] ( { qid = ebb81a9c0c2125c9f12fee33c281dfe2ef5c1596; "qid_data" = { labels = Wristwatch; }; } )

when i am parsing the "qid" value like this :

- (void)updateCompleteWithResults:(NSArray*)results{ NSLog(@"%@",results); NSString *qid = [results valueForKey:@"qid"];

the NSString object is getting a Parentheses around the string (i dont know how) looks like this :

2012-09-12 16:34:17.979 WhatIsIt[1785:707] ( 2e1da5854f3b4f02cd967293cd1364e6d3e0b76a )

so i tried to use :

NSString *string = @" spaces in front and at the end "; NSString *trimmedString = [string stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]];

and the app crashes, any idea?

In your code, the Unit is registered into angular's module as bdUnit:

angular.module('Modelbuildr').factory('bdUnit', Unit.$factory);

Therefore, you should use it like this:

app.controller("MainCtrl", function($scope, bdUnit) { .. });

or explicitly tell angular to alias the bdUnit as Unit:

app.controller("MainCtrl", ['$scope', 'bdUnit', function($scope, Unit) { .. }]);

19206721 0 xml parse from mysqldump in php

I'm trying to parse this xml file to php.

The problem are that i don't know to parse with this xml format obtained with mysqldump.

Can you help me to parsing <field name="observaciones"> in php?

If you want to take a heap dump programmatically, you'll not find suitable APIs in the java.* or javax.* namespace. However, the Sun runtime comes with the HotSpotDiagnosticMXBean which will enable you to take a heap dump by writing the contents of the heap on to a specified file in disk.

If you did want to whitelist for performance reasons, consider using an annotation to indicate which fields to compare. Also, this implementation won't work if your fields don't have good implementations for equals().

P.S. If you go this route for equals(), don't forget to do something similar for hashCode().

P.P.S. I trust you already considered HashCodeBuilder and EqualsBuilder.

12338370 0 Passing php file in ajax

This is my code

<script> $(document).ready(function() { // delete the entry once we have confirmed that it should be deleted $('.delete').click(function() { var parent = $(this).closest('tr'); $.ajax({ type: 'POST', url: 'delete.php', data: 'ajax=1&delete=' + $(this).attr('id'), success: function() { parent.fadeOut(300,function() { parent.remove(); }); } }); }); $('.delete').confirm({ }); }); </script>

My question is why delete.php is not executing? It's in the same folder, do I need type absolure url to this file? But the best of it is that row in table is deleting, but php file is not executing. And second question is why this code is not working without this line:

 $('.delete').confirm({ });

In php file i got this to know is it executed:

<script> alert('aaaa'); </script>

Or even I had change it on echo 'something'; but still not working

You're expressing a real-world constraint in code. Your examples here don't actually show that buying you anything here, so going on the evidence I'd wonder whether it's redundant to express it, or irrelevant to any situation that will actually arise. But if you're ever going to have different kinds of shaders for different kinds of vertex datasets, I'd say you've hit on exactly the right way to express this here.

This problem is actually caused by HTML behaving differently then JQuery. In HTML, spaces and extra lines don't matter.

In HTML, these 2 examples are visually the same when rendered to the page:

<div id="vendor">Barracuda</div>

and

<div id="vendor"> Barracuda </div>

However when you use JQuery's .Text() method, they yield different results.

<div id="vendor">Barracuda</div> $('#vendor').text() // equals "Barracuda"

But this is very different:

<div id="vendor"> Barracuda </div> $('#vendor').text() // equals " Barracuda "

Thus the need to .trim() the results if you can't tailor the HTML, or just want to play it safe.

var thisText = $.trim($(this).text());

30847396 0 RawSourceWaveStream volume control and playback time estimation with Naudio

I'm using Naudio to play audio samples from memory.

 private RawSourceWaveStream waveStream; private MemoryStream ms; private int sampleRate = 48000; private IWavePlayer wavePlayer; //generate sine wave signal short[] buffer = new short[(int)Math.Round(sampleRate * 10.00)]; double amplitude = 0.25 * short.MaxValue; double frequency = 1000; for (int n = 0; n < buffer.Length; n++) { buffer[n] = (short)(amplitude * Math.Sin((2 * Math.PI * n * frequency) / sampleRate)); } byte[] byteBuffer = new byte[buffer.Length * sizeof(short)]; Buffer.BlockCopy(buffer, 0, byteBuffer, 0, byteBuffer.Length); //create audio player to play samples from memory ms = new MemoryStream(byteBuffer); waveStream = new RawSourceWaveStream(ms, new WaveFormat(sampleRate, 16, 1)); //wavePlayer = new WaveOutEvent(); wavePlayer = new DirectSoundOut(); wavePlayer.Init(waveStream); wavePlayer.PlaybackStopped += wavePlayer_PlaybackStopped;

I want to control the Volume of RawSourceWaveStream for each stream separately. (I will play multiple streams).

1) It's enough to use wavePlayer.Volume = volumeSlider1.Volume;? It is deprecated.

2) I see that AudioFileReader make use of SampleChannel for Volume control. If i rewrite Read method for RawSourceWaveStream and add Volume Property should this be a good solution?

3) I want playback time estimation as best as possible (at millisecond level). I saw that the time resolution of WaveOutEvent is about hundred of milliseconds. The time resolution of DirectSoundOut is better, but still not enough.

Thank you in advance!

You can't do assignment in an if statement. It looks as though you are trying to do comparison, however, which uses == rather than =.

In Your CSS Style Sheet

.Textbox { min-width:100%; }

In Your *.aspx

<asp:TextBox CssClass="TextboxStyle" placeholder="Enter the Title" runat="server" ID="TextBox1"></asp:TextBox>

This will update your text box

I think I found the answer. The bcp format spec doesn't work properly! It seems that even for numeric or datetime import fields, you have to specify "SQLCHAR" as the datatype in the .fmt file. Any attempt to use the actual .fmt file generated by "bcp format" is hopeless -- if it gives you SQLINT or SQLDATE lines back, you have to replace those with SQLCHAR for the thing to work, even if the db columns are in fact numeric or date/datetime types.

What a crock!

I am using org.jboss.soa.esb.actions.soap.SOAPClient in my ESB. And i am trying to get the HTTP status code or any exception if SOAPClient fails to send request. Here , there may be plenty of reasons for unsuccesful delivary ex :--404,500 etc.... My requirment is to catch any error or exception (can be soap fault exception) or http status code in ESB so that i do some bussiness logic based on Exception . I tried to use below code but unable to receive any exception.

22190456 0 "accessorize" method - Ruby, Rack or Sinatra?

I've seen the following idiom, and wonder what does accessorize mean and where does it come from - Ruby, Rack or Sinatra?

use Rack::Flash, accessorize: [:error, :success]

You can do that! Just create some non-queried parameters for the report and set the value of each textbox to:

=Parameters!ParameterName.Value

...where ParameterName is the actual name of the parameter, as you defined for the report.

34586214 0 Load Earlier Messages in listview like whats app

When i Click load earlier messages the earlier messages get loaded from database but list view scrolls to the top which is not be done , the message should only loaded at the top of list view without its scroll.

Here is my code for main Activity

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.private_group_chat); Intent i = getIntent(); btnLoadMore = new Button(this); btnLoadMore.setText("Load Earlier Messages"); lsvChat = (ListView) findViewById(R.id.lv_messsages); lsvChat.addHeaderView(btnLoadMore); chatModel = new ArrayList<ChatModel>(); db = new Database3(getApplicationContext()); chatModel = db.getSelectedIncidentDetails(getApplicationContext(), groupId, count); chatAdapter = new ChatAdapterGroup(getApplicationContext(), chatModel); lsvChat.setAdapter(chatAdapter); discoverModel = new ArrayList<DiscoverModel>(); dm = new DiscoverModel(); }

here is my base adapter......

public class ChatAdapterGroup extends BaseAdapter { private Context context; private LayoutInflater inflater; int count = 0; private ArrayList<ChatModel> list; public ChatAdapterGroup(Context context, ArrayList<ChatModel> list) { this.context = context; this.list = list; inflater = (LayoutInflater) context .getSystemService(context.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { return list.size(); } @Override public Object getItem(int position) { return list.get(position); } @Override public long getItemId(int position) { return position; } private class ViewHolder { TextView txt_left; TextView txt_right; TextView tv_fromName; RelativeLayout rl_left; RelativeLayout rl_right; } @Override public View getView(final int position, View v, ViewGroup arg2) { final ViewHolder holder; if (v == null) { holder = new ViewHolder(); v = inflater.inflate(R.layout.chat_adapter, null); holder.txt_left = (TextView) v.findViewById(R.id.txt_left); holder.txt_right = (TextView) v.findViewById(R.id.txt_right); holder.tv_fromName = (TextView) v.findViewById(R.id.tv_fromName); holder.rl_left = (RelativeLayout) v.findViewById(R.id.rl_left); holder.rl_right = (RelativeLayout) v.findViewById(R.id.rl_right); v.setTag(holder); } else { holder = (ViewHolder) v.getTag(); } if (list.get(position) != null) { if (list.get(position).getGroup_cordinate() .equalsIgnoreCase("left")) { holder.txt_left.setText("" + list.get(position).getGroup_messages_recive()); holder.tv_fromName.setText("" + list.get(position).getFrom_name_recive()); holder.txt_left.setTextColor(Color.parseColor("#000000")); holder.rl_right.setVisibility(View.GONE); holder.rl_left.setVisibility(View.VISIBLE); } else { holder.txt_right.setText("" + list.get(position).getGroup_messages_recive()); holder.rl_left.setVisibility(View.GONE); holder.rl_right.setVisibility(View.VISIBLE); } } v.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub // notifyDataSetChanged(); } }); return v; } }

Go check these styles:

.nivo-controlNav a h1 { color: #E4007B; font: bold 15px/20px Arial; text-transform: none; }

and add these after:

.nivo-controlNav a.active h1 { color: #000; }

This should work.

26511016 0 relative width and height in storyboard?

I've been developing an ios app and the layout is driving me absolutely mad. So i have a CollectionViewCell, in this collectionviewcell i have 2 UIViews. What i want to know is how can i set width and height of my views relative to their parent container.

I've already attempted this

NSLayoutConstraint *c = [NSLayoutConstraint constraintWithItem:bottomView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:topView multiplier:1.5 constant:0];

from the other stack post but it does nothing.

Ive tried to set the height of one of the containers programaticaly but that also doesnt work. Here is the code that sets the layout of the collectionviewCell which is the super view and works.

 CGFloat screenWidth = screenRect.size.width; CGFloat screenHeight = screenRect.size.height; CGFloat marginWidth = 10.f; CGFloat itemWidth = (screenWidth / 2.0f) - (1.5f * marginWidth); [self layout].itemSize = CGSizeMake(itemWidth, itemWidth * 1.3f);

Ive tried to set the height of the view relative to the collectionviewcell with the code below

 CGFloat height = (((itemWidth * 1.3f)/3)*2); CGRect imageFrame = self.imagePanel.frame; imageFrame.size.width = (screenWidth / 2.0f); imageFrame.size.height = height; [self.imagePanel setFrame:imageFrame];

But again this doesnt work :( How can i achieve this? Is there any way to do this through the storyboard?

Try to use:

jQuery(document).ready(function(){ var target = jQuery('.product-image'); target.mouseenter(function(){ jQuery(this).find('.popUpPrice button').show(); }); });

Also target is already a jQuery object. You can just use target.mouseenter instead of jQuery(target).mouseenter

What I have tried:

clear, rebuild, recreate project
change compile version of java to 1.7
enable multiDexEnabled with big memory size allocation for multidex configuration
delete appcompat and support dependencies
changed version of stickerfactory to latest (":+")

Nothing works.

The analogic problem is with quickblox jar libraries also! (all jar libs are taken from quickblox chat sample (jars directory))

40665833 0 Siddhi logical pattern AND only works for a pair of events

I have been doing some tests using WSO2 Siddhi language and I came across something that I did no fully understand. It seems like a bug/limitation but I would like to hear your opinion/recommendations.

Creating a chain of events using logical pattern. I tried to create a chain of 3 events connected by AND operator. Below is a very simple query I created:
```
from ea=event_a[ea.status == 1] and eb=event_b[eb.status == 2] and ec=event_c[ec.status == 3] select 'And_Test' as ID insert into outputStream; 
```

When I try to test it using Siddhi Try it, it shows the following error message:

You have an error in your SiddhiQL at line 10:1, extraneous input 'and' expecting {'[', '->', '#', SELECT, INSERT, DELETE, UPDATE, RETURN, OUTPUT, WITHIN}

However, if I remove the third event from my query, it works fine. Below is the query that works fine:

from ea=event_a[ea.status == 1] and eb=event_b[eb.status == 2] select 'And_Test' as ID insert into outputStream;

It seems that I can only use AND for a pair of events. As I mentioned before, it seems like a bug/limitation. I tested it on both WSO2 CEP 4.1.0 and WSO2 CEP 4.2.0.

2949221 0 How to find unmapped properties in a NHibernate mapped class?

I just had a NHibernate related problem where I forgot to map one property of a class.

A very simplified example:

public class MyClass { public virtual int ID { get; set; } public virtual string SomeText { get; set; } public virtual int SomeNumber { get; set; } }

...and the mapping file:

<?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="MyAssembly" namespace="MyAssembly.MyNamespace"> <class name="MyClass" table="SomeTable"> <property name="ID" /> <property name="SomeText" /> </class> </hibernate-mapping>

In this simple example, you can see the problem at once:
there is a property named "SomeNumber" in the class, but not in the mapping file.
So NHibernate will not map it and it will always be zero.

The real class had a lot more properties, so the problem was not as easy to see and it took me quite some time to figure out why SomeNumber always returned zero even though I was 100% sure that the value in the database was != zero.

So, here is my question:

Is there some simple way to find this out via NHibernate?
Like a compiler warning when a class is mapped, but some of its properties are not.
Or some query that I can run that shows me unmapped properties in mapped classes...you get the idea.

(Plus, it would be nice if I could exclude some legacy columns that I really don't want mapped.)

EDIT:
Okay, I looked at everything you proposed and decided to go with the meta-data API...that looks the easiest to understand for me.
Now that I know what to search for, I found some examples which helped me to get started.
So far, I have this:

Type type = typeof(MyClass); IClassMetadata meta = MySessionFactory.GetClassMetadata(type); PropertyInfo[] infos = type.GetProperties(); foreach (PropertyInfo info in infos) { if (meta.PropertyNames.Contains(info.Name)) { Console.WriteLine("{0} is mapped!", info.Name); } else { Console.WriteLine("{0} is not mapped!", info.Name); } }

It nearly works, except one thing: IClassMetadata.PropertyNames returns the names of all the properties except the ID.
To get the ID, I have to use IClassMetadata.IdentifierPropertyName.

Yes, I could save .PropertyNames in a new array, add .IdentifierPropertyName to it and search that array.
But this looks strange to me.
Is there no better way to get all mapped properties including the ID?

30372135 0 Add buttons to UINavigationController subclass

I'm trying to create reusable subclass of UINavigationController. So here's my code :

 @interface MainNavigationController : UINavigationController ... - (void)viewDidLoad { [super viewDidLoad]; self.navigationBar.barTintColor = primaryOrange; self.navigationBar.tintColor = white; self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"search"] style:UIBarButtonItemStylePlain target:self action:nil]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"menu"] style:UIBarButtonItemStylePlain target:self action:nil]; }

So the problem that the color of navigation bar is changing but the buttons they doesn't appears.
What's I've missed here ?

Update I want to have the same NavigationController (button and color ...) for the NavigationController in my image : enter image description here

Update So I've subclasse my navugationController unn this way :

-(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{ viewController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"search"] style:UIBarButtonItemStylePlain target:self action:nil]; viewController.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"menu"] style:UIBarButtonItemStylePlain target:self action:@selector(showMainMenu)]; } - (id)initWithRootViewController:(UIViewController *)rootViewController { self = [super initWithRootViewController:rootViewController]; if (self) { rootViewController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"search"] style:UIBarButtonItemStylePlain target:self action:nil]; rootViewController.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"menu"] style:UIBarButtonItemStylePlain target:self action:@selector(showMainMenu)]; } return self; }

This work's but the only problem is that when I push a view instead of having back button on left I get Always the search icon, how to fix it (I want to have search button for parent on left , and back button for child view ) ?

16481613 0 BootBox JS for Twitter Bootstrap - how to pass data into the callback function?

JS/JQuery newbie here. I'm using BootBox for Twitter Bootstrap, and I'm trying to pass the value of the id attribute of an a element into the callback function:

<a class="confirmdel" id="<?= $folioid ?>" href="#"> Delete</a> <script> $(document).on("click", ".confirmdel", function(e) { var folioid = ($(this).attr('id')); bootbox.dialog("Do you really want to delete this folio entry?", [{ "label" : "Yes", "class" : "btn-danger", "icon" : "icon-trash", "callback": function() { window.location.replace("deletefolio.php?folioid="+$folioid); } }, { "label" : "No", "class" : "btn", }]); }); </script>

It seems i can't use $(this) inside the callback function because in there it doesn't refer to the a element but to the window instead, and I have no idea how to pass the variable into the callback from outside.

Maybe I'm thinking about it the wrong way entirely.

Any suggestions greatly appreciated!

Use super() as the first line inside your constructor for the reason as shared in an SO-answer here - why-does-this-and-super-have-to-be-the-first-statement-in-a-constructor and you can change your existing code as -

public Car(String name, int modelNo, int seatCap) { super(name, modelNo); this.seatCap = seatCap; }

7404685 0 Packaging JVM with Application While Maintaining an Automated and Repeatable Build Process

I'm currently working on a project that requires us to package a JRE with our application. I'm normally against this as it makes keeping the JRE patched quite difficult, but in this case it is necessary.

What are the best practices for packaging a JRE with an application as part of an automated build process?
Where do you normally store the JRE files so that they can be picked up by your build process? Shared file server? What about making it an artifact in your maven repo?

Just trying to get a feel for what people do in this situation.

Hello I'd like to use flowplayer on a website but I experienced that it is not relieable with my configurations yet.

Using firefox I sometimes got the error 200 stream not found. It seemed as if the url of the clip has not been passed to the player.

using seamonkey the video was played with the configuration in the example bellow all the time propperly.

using epiphany i only get a black screen which might depend on my css.

but now the real problem and question: why do I get the 200 stream not found problem on firefox and how to get rid of it 100% do you have it too?

here is a demo page: http://lehrer-beraten-eltern.de/debug

Personally I would always run some form of sanitation on the data first as you can never trust user input, however when using placeholders / parameter binding the inputted data is sent to the server separately to the sql statement and then binded together. The key here is that this binds the provided data to a specific type and a specific use and eliminates any opportunity to change the logic of the SQL statement.

This is valid Python syntax when it is located in a module, but in the interactive interpreter you need to separate blocks of code with a blank line.

The handy rule of thumb here is that you can't start a new block with if, def, class, for, while, with, or try unless you have the >>> prompt.

23842990 0 APEX: How to link application log-in credentials to a table in back-end database

I have made a database and now I am trying to make a front-end application using oracle apex 4(default with oracle-xe 11g). I have included the following table for user credentials in my database.

Manager(managerid{PK},name,username,password)

I know I can create many end-user accounts from the apex for an application. But, users of application will be managers only and I have a table for them in database so it would be illogical to create separate accounts and information when I have them already in database.

My question is, how can I link the authorization of front-end application with the above table?

I think it's unlikely that this is possible using only client-side Flash. In theory maybe it would be possible to simulate playback speed of video by doing manual seeking, but that wouldn't provide for audio. Using Flash 10+, it is now possible to manipulate audio data manually, though that doesn't mean it's possible to manipulate in context of a audio/video stream . (Example: http://www.kelvinluck.com/2008/11/first-steps-with-flash-10-audio-programming/)

If the Google Video player you provided a screen shot of was Flash based, then I think it's very likely they were using a media server to handle playback speed changes. (Just FYI, google at one time had multiple video players available, and not all were Flash based.) Recent versions of Flash Media Server supposedly also support playback speed adjustment. (I couldn't find anything authoritative though, and I don't know if handling of audio is included.)

One other thought, just FWIW, HTML5 video includes support for speed adjustment the playbackRate property. Perhaps that will eventually be an option for you.

I had this same issue. Turns out I needed to traverse the subview tree like so:

var subView = alertController.view.subviews.first as! UIView var contentView = subView.subviews.first as! UIView contentView.backgroundColor = UIColor(red: 233.0/255.0, green: 133.0/255.0, blue: 49.0/255.0, alpha: 1.0)

38499772 0 VS2015 - Referencing .so files in Android project

I have an Android project composed of a Java layer for the UI, and a C++ layer for the core of the application that contains most of the code.

These two layers are two separate Visual Studio 2015 projects/solutions, the "UI" project being a "Basic Application (Android, Gradle)" project, and the "Core" project being a "Dynamic Shared Library (Android)" generating a .so which is loaded by the Java on startup.

I would like my "UI" project to reference the "Core" project without making the C++ code accessible when openning the "UI" project.

What I have thought so far :

Adding a reference to the "Core" project in the "UI" project, which seems to be the clean way to do this, but which also makes the C++ code accessible, which I don't want to be possible.
Not creating a reference to the "Core" project in the "UI" project but simply "referencing" the .so generated by the "Core" project into the "UI" project. However I don't know how to do that. And because there will not be an actual reference to the "Core" project, compiling the "UI" project will not automatically recompile the "Core" project if a modification was made to it, forcing me to do it manually.

Is there a clean way to do what I want to do ? Thank you.

String supports only + and +=. All other arithmetic and compound statements are invalid at compile time itself.

From String docs

The Java language provides special support for the string concatenation operator ( + ), and for conversion of other objects to strings.

That doesn't mean it support all other operations.

To substract or to make parts of string, there are other methods like substring, split etc.

Here are some examples to substring, from docs

 String c = "abc".substring(2,3);

34915524 0 Thread 1:EXC_BAD_INSTRUCTION error when calling "addObjectsFromArray"method for NSMutableArray

I have created a program where it calculates the borders of certain countries based on a Custom Object being inputed into a function. This function returns an array of custom objects. I keep getting this error when trying to add this array to a NSMutableArray. The error is called "Thread 1: EXC_BAD_INSTRUCTION(code=EXC_1386_INVOP, subcode=0x0)".

Here is my adding code:

@IBOutlet var Label: UILabel! @IBOutlet var imageView: UIImageView! override func viewDidLoad() { //Afganistan Afghanistan.name = "Afghanistan" Afghanistan.borders.addObjectsFromArray(relate(Afghanistan)) Label.text = String((Afghanistan.borders[0] as! develop).name) }

Here is the relate method along with the group dictionary:

func relate(X : develop) -> Array<develop>{ var A : [develop] = [] for (_, value) in groups { for y in value { if y.name == X.name { for i in value { if i.name != X.name { A.append(i) } } } } } return A } //Groups var groups = [ "one": [Afghanistan] ]

28674171 0 Having problems splitting a long string with preg_match_all

I have a variable (text) and it is updated with sentences every time there is an update. When i display this array it turns into 1 long sentence, and i want to break this up in single sentences for readability.

<?php $pattern = '~\\d+-\\d+-\\d{4} // \\w+: ~ '; $subject = '01-02-2015 // john: info text goes here 10-12-2015 // peter: some more info '; $matches = array(); $result = preg_match_all ($pattern, $subject, $matches); ?>

Which gives this output:

$matches: array ( 0 => array ( 0 => '01-02-2015 // john: ', 1 => '10-12-2015 // peter: ', ), )

I'd like the output to be:

$matches: array ( 0 => array ( 0 => '01-02-2015 // john: info text goes here', 1 => '10-12-2015 // peter: some more info', ), )

I need the output to be like this so i can use a foreach loop to print each sentence.

ps. I'd like to try to get it to work this way first, because otherwise i'd need to change a lot of entries in the database.

pps. I'm also not a hero with regex as you can see, so i hope someone can help me out!

While this will work, it's probably best (from a readability and performance standpoint) to use a dedicated event library. If you don't want to do that, this is a neater way to do it.

jQuery allows creation of documentFragments, which just live in memory as an object. It isn't added to your page, and events can only be triggered on it by using the returned value (here stored in window.events).

window.events = $('<div>'); events.on('changeSettings',function(e,param1){ // do something }); events.trigger('changeSettings', ['value']);

fiddle

Here's an example using radio.js, which does events and nothing else.

radio('changeSettings').subscribe(function(data1, data2) { //do something with data1 and data2 }); radio('changeSettings').broadcast(data1, data2);

You could also do something like this, which allows refactoring and minification.

var events = {changeSettings: radio('changeSettings')}; events.changeSettings.subscribe(function(data1, data2) { //do something with data1 and data2 }); events.changeSettings.broadcast(data1, data2);

21810145 0 Paypal checkout opens on a separate tab - how to change this?

I have found that the Paypal generated buttons is a very good solution for my wife's website. However, whenever someone presses on the "add to cart" button, he/she is taken to a separate Internet Explorer tab. That's fine. However, if they chose to "continue shopping", IE tries to close the Paypal tab and asks the user's permission to do so. This is not really ideal from the user experience point of view.

Can I force the Paypal Checkout to open in the same IE tab as the main website?

Thank you.

As you .inline append to DOM dynamically, so ordinary binding will not work here. You need delegate event handler to perform like following:

$('#selectResult').on('hover', '.inline', function(e) { if(e.type == "mouseenter") { alert('In'); } else { alert('Out'); } });

.on() method for delegate event handler need to use as following:

$(container).on(eventName, target, handlerFunction);

Here, container points to the element that is Static-element i.e. belongs to DOM at page load, not append dynamically. Try to avoid document or body as container reference.

21452934 0 What is the easiest way to push a very messy local git repo to a remote git repo, chunk by chunk?

I have forked and then cloned a git repo that my research group is working on a while ago. I was (and still am) new to git, but I happily created a few branches, occasionally merging them with the changes from the remote source. I have also pushed my changes every now and again to my remote forked version of the repo, but I never pushed much to the original repo, because my work was undone and nobody demanded it.

Here is the situation: I have a whole load of changes committed and pushed to my remote repo. Almost none of it made it to the original remote repo that the rest of the group is working on. Just doing one big diff is out of the question, because there is still way too much scruffy unfinished work that nobody besides me might need. How do I start pushing selected changes (as in, selected manually, by hand) to the remote repo, chunk by chunk?

I am not fluent in git, and I wonder if I have to make a clean clone and start from there. Is there a smarter way of approaching my situation?

Thank you.

You don't instantiate ConfigParser when you assign it to the self.scfgs or self.cfg attributes; so when you then call read on it, you're calling an unbound method via the class, rather than a method on the instance.

It should be:

self.cfg = ConfigParser()

etc

31138279 0 Standard output strange behavior

I have an issue using Eclipse cdt and I am facing a strange behavior:

cout << "Hello world" << endl; aFunction(); // The output here is Hello world // END

When I take off the endl the output is nothing

cout << "Hello world"; aFunction(); // No output // END

and when I put the endl later it works fine :

cout << "Hello world"; aFunction(); cout << endl; // output is Hello world // END

Now, I can't provide the function code, because it will take me a thousand of lines.

However, I tried this with a function that does nothing void toto(){} and there was not this strange thing .

cout << "Hello world"; toto(); // Gives me Hello world // END

What I want to know is what can cause this ??

EDIT : The tests with foo are tested alone (no other instructions), In the other tests, I initialize a structure that I give as a parameter to aFunction. The function uses some metaprogramming and there is a lot of code i need to show so you understand it.

You could use the property accessor, like the assignment.

var f = function() { console.log("Hello! " + f.x); } f.x = "Whoohoo"; console.log(f.x); f();

For stable access, you could use a named function

var f = function foo() { console.log("Hello! " + foo.x); } // ^^^ >>>>>>>>>>>>>>>>>>>>>>>>>>> ^^^ f.x = "Whoohoo"; console.log(f.x); f();

in the above sample how can I make a generic RetryOperation class which can take any function and call it 3 or 4 times with an interval before informing the user that the operation cannot be completed.

I'm hoping it's possible to make a generic method rather than have duplicate code in all the service call functions

any samples in C# or vb.net will be really appreciated.

You question isn't clear. Frequency has nothing to do with getting signal strength. Signal strength is calculated by the WiFi client upon receiving of frame. If you want to get every channel signal strength, you need to do WiFi scanning. Scanning is defined in 802.11 (WiFi) protocol and is done every n time units without user intervention.

Middleware recommendation

The answer by @miro is very good but can be improved as in the following middleware in a separate file (as @ebohlman suggests).

The middleware

module.exports = { configure: function(app, i18n, config) { app.locals.i18n = config; i18n.configure(config); }, init: function(req, res, next) { var rxLocale = /^\/(\w\w)/i; if (rxLocale.test(req.url)){ var locale = rxLocale.exec(req.url)[1]; if (req.app.locals.i18n.locales.indexOf(locale) >= 0) req.setLocale(locale); } //else // no need to set the already default next(); }, url: function(app, url) { var locales = app.locals.i18n.locales; var urls = []; for (var i = 0; i < locales.length; i++) urls[i] = '/' + locales[i] + url; urls[i] = url; return urls; } };

Also in sample project in github.

Explanation

The middleware has three functions. The first is a small helper that configures i18n-node and also saves the settings in app.locals (haven't figured out how to access the settings from i18n-node itself).

The main one is the second, which takes the locale from the url and sets it in the request object.

The last one is a helper which, for a given url, returns an array with all possible locales. Eg calling it with '/about' we would get ['/en/about', ..., '/about'].

How to use

In app.js:

// include var i18n = require('i18n'); var services = require('./services'); // configure services.i18nUrls.configure(app, i18n, { locales: ['el', 'en'], defaultLocale: 'el' }); // add middleware after static app.use(services.i18nUrls.init); // router app.use(services.i18nUrls.url(app, '/'), routes);

Github link

The locale can be accessed from eg any controller with i18n-node's req.getLocale().

RFC

What @josh3736 recommends is surely compliant with RFC etc. Nevertheless, this is a quite common requirement for many i18n web sites and apps, and even Google respects same resources localised and served under different urls (can verify this in webmaster tools). What I would recommended though is to have the same alias after the lang code, eg /en/home, /de/home etc.

#include <iostream> class A { public: enum class B { val1, val2 }; typedef B InnerEnum; static void f(InnerEnum val) { std::cout << static_cast<int>(val); } }; template <typename T1> void f(typename T1::InnerEnum val) { T1::f(val); } int main() { A::InnerEnum v = A::InnerEnum::val1; f(v); return 0; }

Yes, it was a bug in the control, it could not start document processing/calculating while it is invisible (or is placed in an invisible container). This bug is fixed in the context of this ticket: https://www.devexpress.com/Support/Center/Question/Details/T198005.

The hotfix is already requested and I believe it will be available in the nearest days.

The abstract operation that converts to a boolean is called ToBoolean:

Undefined: false
Null: false
Boolean: The result equals the input argument (no conversion).
Number: The result is false if the argument is +0, −0, or NaN; otherwise the result is true.
String: The result is false if the argument is the empty String (its length is zero); otherwise the result is true.
Object: true.

However, this operation is internal and not available.

But there are some workaround to use it:

Logical NOT Operator ( ! )
```
!!variable; 
```
Conditional Operator ( ? : )
```
variable ? true : false; 
```
Boolean
```
Boolean(variable) 
```

You need to use something like Rollup, Webpack, or Browserify. This statement import FormComponent from './FormComponent.js'; doesn't mean anything on the client. No browser natively supports it so you need something like the tools mentioned above to turn it into something the browser can actually use.

Without them you just have to load the files in your index.html.

Too much recursion means that something is looping over and over again, possibly infinitely. The reason that's happening with your current code is because <a> is a parent of <img>, so any click event on <img> bubble up to the parent <a> (search for "event bubbling" in Google). So your code is basically saying "when someone clicks on <a>, trigger a click on <img> and then <a> (because of event bubbling)" -- which of course causes the code to run again.

If the JavaScript plugin already has binded events to clicks on the image, I don't see why you need to bind a click event to the parent <a> that simply clicks on the image. What do you need to happen that isn't already happening when the user clicks on the <img> -- without including your jQuery code?

41041344 0 Retrieve Google Analytics quotas consumption via API

i want to be able to fetch all the quotas status related to the google analytics API consumption. One part of it seems to be available via IAM:

First, accessing to these data through an API would be nice..is it possible with the IAM API ?? If so, can i get a sample ?

Next, i need one more data: the google analytics quota consumption PER VIEW (which is limited to 10.000 queries per view per day)..is it also possible to fetch this data, one way or another ?

Cheers,

8835956 0 Make CVDisplayLink + Automatic Reference Counting play well together

I recently switched from using NSTimer to CVDisplayLink to redraw my OpenGL animation, but i've got a little problem making it work with ARC switched on:

/* * This is the renderer output callback function. */ static CVReturn displayLinkCallback(CVDisplayLinkRef displayLink, const CVTimeStamp* now, const CVTimeStamp* outputTime, CVOptionFlags flagsIn, CVOptionFlags* flagsOut, void* displayLinkContext) { // now is the time to render the scene [((__bridge BDOpenGLView*)displayLinkContext) setNeedsDisplay:YES]; // always succeeds, because we don't actually do anything here anyway return kCVReturnSuccess; }

The display link callback function has to be written in C, to be used as a parameter for

// set the renderer output callback function CVDisplayLinkSetOutputCallback(displayLink, &displayLinkCallback, (__bridge void*)self);

So i can't use self within in the callback, but using ((__bridge BDOpenGLView*) displayLinkContext) produces a memory leak:

objc[29390]: Object 0x1001b01f0 of class NSConcreteMapTable autoreleased with no pool in place - just leaking - break on objc_autoreleaseNoPool() to debug

I read, that i have to set up an NSAutoreleasePool myself, but i can't with ARC switched on.

Am i missing something?

There are several techiniques for removing outliers or refining matches:

Cross check
Ratio test
RANSAC+Homography for planar shapes

I usually apply the last two ones.

RATIO TEST:

BFMatchermatcher(CV_L2); vector<vector<DMatch>>nearest_neighbors; matcher.radiusMatch( right_points_to_find_flat, right_features_flat, nearest_neighbors, 2.0f); // Check that the found neighbors are unique (throw away neighbors // that are too close together, as they may be confusing) std::set<int>found_in_right_points; // for duplicate prevention for(inti=0;i<nearest_neighbors.size();i++) { DMatch _m; if(nearest_neighbors[i].size()==1) { _m = nearest_neighbors[i][0]; // only one neighbor } else if(nearest_neighbors[i].size()>1) { // 2 neighbors – check how close they are double ratio = nearest_neighbors[i][0].distance / nearest_neighbors[i][1].distance; if(ratio < 0.7) { // not too close // take the closest (first) one _m = nearest_neighbors[i][0]; } else { // too close – we cannot tell which is better continue; // did not pass ratio test – throw away } } else { continue; // no neighbors... :( }

RANSAC+Homography:

std::vector<Point2f> object; std::vector<Point2f> scene; for( int i = 0; i < good_matches.size(); i++ ) { //-- Get the keypoints from the good matches object.push_back( keypoints_object[ good_matches[i].queryIdx ].pt ); scene.push_back( keypoints_scene[ good_matches[i].trainIdx ].pt ); } Mat H = findHomography( object, scene, CV_RANSAC, status ); //draw only the matches considered inliers by RANSAC => status=1 for(i=0;i=object.size();i++){ if(status[i]) { } }

20594029 1 How do you order what websites reply in Skype4Py?

I use Skype4Py for my Skype Bot I've been working on.
I was wondering how I could order what the APIs respond.
For example, if I wanted to get the weather, I'd type !weather
and it would respond with:

Gathering weather information. Please wait...
Weather: { "data": { "current_condition": [ {"cloudcover": "0", "humidity": "39", "observation_time": "11:33 AM", "precipMM": "0.0", "pressure": "1023", "temp_C": "11", "temp_F": "51", "visibility": "16", "weatherCode": "113", "weatherDesc": [ {"value": "Clear" } ], "weatherIconUrl": [ {"value": "http://cdn.worldweatheronline.net/images/wsymbols01_png_64/wsymbol_0008_clear_sky_night.png" } ], "winddir16Point": "N", "winddirDegree": "0", "windspeedKmph": "0", "windspeedMiles": "0" } ], "request": [ {"query": "90210", "type": "Zipcode" } ] }}

and I would like to have it be more like:

Weather:
Current Temp: 51 F | 22 C
Humidity: 39%
Wind Speed: 0 MPH

or something cleanly ordered out like that.
That way it looks less ugly in Skype, and looks more professional.

I should've added the code:

 def weather(zip): try: return urllib2.urlopen('http://api.worldweatheronline.com/free/v1/weather.ashx?q='+zip+'&format=json&num_of_days=1&fx=no&cc=yes&key=r8nkqkdsrgskdqa9spp8s4hx' ).read() except: return False

That is my functions.py

This is my commands.py:

 elif msg.startswith('!weather '): debug.action('!weather command executed.') send(self.nick + 'Gathering weather information. Please wait...') zip = msg.replace('!weather ', '', 1); current = functions.weather(zip) if 4 > 2: send('Weather: ' + current) else: send('Weather: ' + current)

Like I stated, I'm using Skype4Py, and yeah.

14386487 0 Bootstrap progress bar using $.get

I realize there are a good number of progress bar related questions already present on SO. I browsed through many of them and was unable to get things working.

Simply put, I am developing a page in JSP and I want to use an animated progress bar within bootstrap to display while the calls are being made for the data.

HTML:

<div class="row-fluid"> <div class="span12 progress progress-striped active"> <div id="searchAnimation" class="bar" hidden="true"></div> </div> </div>

Servlet (Not sure if this part is relevant, but better safe than sorry):

@Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { //String that gets returned as HTML StringBuilder returnAsHTML = new StringBuilder(); //See if the class is closed, has a lab, or is just a regular class for(ClassInfo classes : springClassListings) { //Class is full, style accordingly if(classes.getSectionMeetingInfo().contentEquals("LEC") && classes.getSectionEnrolled().contentEquals("0")) { returnAsHTML.append(closedClass(classes)); } else if(classes.getSectionMeetingInfo().contentEquals("LAB")) //These are labs, style accordingly { returnAsHTML.append(labClass(classes)); } else //These are normal classes without lab components { returnAsHTML.append(openClass(classes)); } } response.setContentType("text/html"); response.setCharacterEncoding("UTF-8"); response.getWriter().write(returnAsHTML.toString()); }

And my scripting:

//Serves up the data $('#btnData').click(function() { //THIS IS THE PROGRESS BAR $("#searchAnimation").show(); $.get('daoServlet', function(responseText) { $('#dataDisp').html(responseText); }); });

I get the idea, % the width of the progress bar by a where the $.get call is at in terms of getting the data. I just don't understand how to do it.

PS - I know my for/if in the doGet is a nasty anti pattern, I just haven't figured out a way around it yet.

original = raw_input("Please type in a word: ") firstLetter = original[0] print firstLetter if firstLetter == "a" or "e" or "i" or "o" or "u": print "vowel" else: print "consonant"

In fact, it doesn't matter what the boolean is in the if statement... if it is == or != , it is still return "vowel". Why?

Qt does not include a compiler. On Windows you're probably either compiling with mingw or Visual C++. Either way, the issue is that you're calling a function that expects a wide character string but you're trying to hand it an 8-bit character string.

For compatibility reasons, Win32 uses a different set of API functions if you have _UNICODE defined. In your case, you do have _UNICODE defined. You can continue using the 8-bit std::string but simply change the method from LoadImage() to LoadImageA(). Or if you don't mind changing your Bitmap class, you could switch from std::string to std::wstring to take advantage of Windows' Unicode features.

But perhaps the larger question is why use Win32 to load bitmaps and std::string if you're using Qt? Qt's QImage class and QString class provide a full-featured, cross-platform strings and image loaders. Like any comprehensive framework, Qt works best if you only use external features on an as-needed basis.

39814785 0 Acknowledgements in socket.io when using mongoose

I use socket.io to communicate between server and client.

On the server, I have

socket.on('new object', (id, object) => { Model.findByIdAndUpdate(id, { $addToSet: { objects: object } }, { new: true }).then(model => { io.sockets.emit('new object', object); }).catch(err => { console.log(err); }); });

So when a new object is created, I broadcast it to all sockets (including the sender).

What I want is to tell the client who started this process from the client if everything was successful.

I have found http://socket.io/docs/#sending-and-getting-data-(acknowledgements), but I don't know exactly how to do it.

I guess I should do something like

socket.on('new object', (id, object, callbackFunction) => { Model.findByIdAndUpdate(id, { $addToSet: { objects: object } }, { new: true }).then(model => { callbackFunction('success'); io.sockets.emit('new object', object); }).catch(err => { callbackFunction('error'); }); });

and on the client have

socket.emit('new object', id, object, function (msg) { alert(msg); });

but is this correct? I guess there will be a problem of calling callbackFunction inside then and catch.

Is there a way in SQL code to make it so if DOG..DOGID is invalid use DOG2..DOGID?

What you might be seeing is that until the alert box is dismissed, the code afterwards is not executed. The alert command is a blocking one.

Perhaps you can use console.log() for debugging purposes of this feature. This will not block your code and it will be executed on the keydown event.

My intention is to send this crash log (if exists) to a server so that we can analyse the log without user intervention. There are several crash reporting services (e.g. bugsense, crashlytics) that are able to do this, so I assume a custom implementation should be possible?

33312748 0 why dont IDE's offer built in code timing like break points?

I find timing my code for performance to be a bit of a headache and I have to assume this is a common problem for folks.

Adding in a bunch of code to time my loops is great but often there is more overhead in adding the timing checks than adding a parallel task. making a loop parallel can take seconds whereas adding in timing chunks requires several lines of code and be dangerous if forgotten.

So... My question is why dont IDE's include this ability to time chunks of code like a break point? Something like i mark a section of code and tell it to dump the timing output to a console with some options to make it more readable. averages and such.

I know break points can seriously hamper performance but there must be an easier way to time specific chunks of code then to write all my own timing routines for each chunk of code i want to check.

After you initialize the PDO object try setting the error mode higher.

The default is PDO::ERRMODE_SILENT which will output no warnings/errors. With this default setting, you have to poll errorInfo() to see error details.

3528311 0 Simple Transactions

I have 2 linq 2 SQL statements I'd like to be in a transaction (the SQL server is remote, outside firewalls etc) all other communication works but when I wrap these 2 statements in a TransactionScope() I begin having to configure MSDTC which we did, but then there are firewall issues (I think) is there a simpler way?

the basics of what I want to do boil down to this: (both are stored procs under the hood)

using (var transactionScope = new TransactionScope()) { Repository.DataContext.SubmitChanges(); Repository.DataContext.spDoFinalStuff(tempID, ref finalId); transactionScope.Complete(); }

What is the simplest way to achieve this?

EDIT:
first I got this: The transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D024) On our servers I followed the instructions here to correct this. However the instructions don't seem to apply to windows 7 (my dev box) see my comment on above answer.

after correcting the issue (on the non win7 boxes) I get this: The transaction has already been implicitly or explicitly committed or aborted (Exception from HRESULT: 0x8004D00E) which some googling suggested may be firewall issue.

EDIT
I just discovered the remote DB is SQL 2000

Here's my solution:

var items = [ { id: 1, name: 'bill' }, { id: 2, name: 'sam' }, { id: 3, name: 'mary' }, { id: 4, name: 'jane' } ]; var order = [ { id: 1, sortindex: 4 }, { id: 2, sortindex: 2 }, { id: 3, sortindex: 1 }, { id: 4, sortindex: 3 } ]; _(items) .indexBy('id') .at(_.pluck(_.sortBy(order, 'sortindex'), 'id')) .pluck('name') .value(); // → [ 'mary', 'sam', 'jane', 'bill' ]

Here's what's going on:

The indexBy() function transforms items into an object, where the id values are the keys.
The at() function gets values from the object, in order, of the passed in keys.
The sortBy() function sorts order by the sortindex key.
The pluck() function gets the sorted id array.

If you're gathering facts, you can access hostvars via the normal jinja2 + variable lookup:

e.g.

- hosts: serverA.example.org gather_facts: True ... tasks: - set_fact: taco_tuesday: False

and then, if this has run, on another host:

- hosts: serverB.example.org ... tasks: - debug: var="{{ hostvars['serverA.example.org']['ansible_memtotal_mb'] }}" - debug: var="{{ hostvars['serverA.example.org']['taco_tuesday'] }}"

Keep in mind that if you have multiple Ansible control machines (where you call ansible and ansible-playbook from), you should take advantage of the fact that Ansible can store its facts/variables in a cache (currently Redis and json), that way the control machines are less likely to have different hostvars. With this, you could set your control machines to use a file in a shared folder (which has its risks -- what if two control machines are running on the same host at the same time?), or set/get facts from a Redis server.

For my uses of Amazon data, I prefer to just fetch the resource each time using a tag/metadata lookup. I wrote an Ansible plugin that allows me to do this a little more easily as I prefer this to thinking about hostvars and run ordering (but your mileage may vary).

Your solution will almost definitely end up involving ssh in some capacity.

You may want something to help manage the execution of commands on multiple servers; ansible is a great choice for something like this.

For example, if I want to install libvirt on a bunch of servers and make sure libvirtd is running, I might pass a configuration like this to ansible-playbook:

- hosts: all tasks: - yum: name: libvirt state: installed - service: name: libvirtd state: running enabled: true

This would ssh to all of the servers in my "inventory" (a file -- or command -- that provides ansible with a list of servers), install the libvirt package, start libvirtd, and then arrange for the service to start automatically at boot.

Alternatively, if I want to run puppet apply on a bunch of servers, I could just use the ansible command to run an ad-hoc command without requiring a configuration file:

ansible all -m command -a 'puppet apply'

When I build the service, the generated WSDL places all of these classes at the top level, without specifying any delineation by sub-namespace. Therefore, it will define two versions of "Customer". Curiously, it doesn't complain during the build process.

When I host the service and try to reference it with a browser, I get the following error:

The top XML element 'Customer' from namespace 'RE: http://...' references distinct types MyRoot.Sub1.Customer and MyRoot.Sub2.Customer. Use XML attributes to specify another XML name or namespace for the element or types.

I looks like I could use XmlTypeAttribute TypeName to provide an unique class name, but this makes documentation quite a hassle, as everything's going to have two names. Considering the differentiation is already specified by the namespaces, is there any way to utilize that information? I haven't tried using TypeName="Sub1.Customer", etc., but none of the examples that I've seen use this notation, so I'm skeptical.

Is there something else obvious that I'm missing?

This is why we have the REST (and SOAP) protocols.

The desktop makes RESTful requests to your web application. Your web application receives the REST requests and does the real work.

Your code exists in exactly one place -- the web.

33480864 0 How to make the parent view to handle all the OnClick events?

I have a Layout that has a button that shows another view, but only for 1 time, I mean, you click the button, it dissapear and the other view is shown, the second time you should click the parent view of that button and the other view (the one that was shown) should dissapear and the button should appear again. I am trying with clickable:false and focusable:false but it is not working. How can I achieve that?

Since your function is going to return a vector, you will have to make a new vector (i.e. copy elements) in any case. In which case, std::remove_copy_if is fine, but you should use it correctly:

#include <iostream> #include <vector> #include <set> #include <iterator> #include <algorithm> #include <functional> std::vector<int> filter(const std::vector<int>& all, const std::set<int>& bad) { std::vector<int> result; remove_copy_if(all.begin(), all.end(), back_inserter(result), [&bad](int i){return bad.count(i)==1;}); return result; } int main() { std::vector<int> all_items = {4,5,2,3,4,8,7,56,4,2,2,2,3}; std::set<int> bad_items = {2,8,4}; std::vector<int> filtered_items = filter(all_items, bad_items); copy(filtered_items.begin(), filtered_items.end(), std::ostream_iterator<int>(std::cout, " ")); std::cout << std::endl; }

To do this in C++98, I guess you could use mem_fun_ref and bind1st to turn set::count into a functor in-line, but there are issues with that (which resulted in deprecation of bind1st in C++0x) which means depending on your compiler, you might end up using std::tr1::bind anyway:

remove_copy_if(all.begin(), all.end(), back_inserter(result), bind(&std::set<int>::count, bad, std::tr1::placeholders::_1)); // or std::placeholders in C++0x

and in any case, an explicit function object would be more readable, I think:

struct IsMemberOf { const std::set<int>& bad; IsMemberOf(const std::set<int>& b) : bad(b) {} bool operator()(int i) const { return bad.count(i)==1;} }; std::vector<int> filter(const std::vector<int>& all, const std::set<int>& bad) { std::vector<int> result; remove_copy_if(all.begin(), all.end(), back_inserter(result), IsMemberOf(bad)); return result; }

If you slice a string with a negative number, Python counts backward from the end.

complement = {'A': 'T', 'C': 'G', 'G': 'C', 'T': 'A'} s = "AAAAAAAAAACCCCCCCCCCTTTTTTTTTTGGGGGGGGGG" "".join(complement[c] for c in s[-20:-10])

EDIT:

Your edit looks about right to me, yes. I am very bad at checking for fencepost errors, but you're better placed to see those than I am anyway!

I've rewritten your code to be more Pythonic, but not changed anything substantial.

bc = {'A': 'T', 'C': 'G', 'G': 'C', 'T': 'A', 'N':'N'} f = open('chr22.fa') l = ''.join(line.strip() for line in f) f.seek(0) for line in f: fields = line.split('\t') gene_ID, chr, strand = fields[:2] start = int(fields[3]) end = int(fields[4]) if strand == '-': start, end = -(start + 1), -(end + 1) geneseq = ''.join(bc[base.upper()] for base in l[start:end])

Alternatively, you could also use Apache Ruta, either with the workbench (recommended to get started) or with java code.

For the latter, I created an example project at https://github.com/renaud/annotate_ruta_example. The main parts are:

a list of names in src/main/resources/ruta/resources/names.txt (a plain text file)

Mark John Rabbit Owl Curry ATH-MX50 CC234

a Ruta script in src/main/resources/ruta/scripts/Example.ruta

PACKAGE example.annotate; // optional package def WORDLIST MyNames = 'names.txt'; // declare dictionary location DECLARE Name; // declare an annotation Document{-> MARKFAST(Name, MyNames)}; // annotate document

and some java boilerplate code to launch the annotator:

JCas jCas = JCasFactory.createJCas(); // the sample text to annotate jCas.setDocumentText("Mark wants to buy CC234."); // configure the engine with scripts and resources AnalysisEngine rutaEngine = AnalysisEngineFactory.createEngine( RutaEngine.class, // RutaEngine.PARAM_RESOURCE_PATHS, "src/main/resources/ruta/resources",// RutaEngine.PARAM_SCRIPT_PATHS, "src/main/resources/ruta/scripts", RutaEngine.PARAM_MAIN_SCRIPT, "Example"); // run the script. instead of a jCas, you could also provide a UIMA collection reader to process many documents SimplePipeline.runPipeline(jCas, rutaEngine); // a simple select to print the matched Names for (Name name : JCasUtil.select(jCas, Name.class)) { System.out.println(name.getCoveredText()); }

there is also some UIMA type (annotation) definitions, check src/main/resources/desc/type/ExampleTypes.xml, src/main/resources/META-INF/org.apache.uima.fit/types.txt and src/main/java/example/annotate.

how to test it

The behavior you so beautifully demonstrated is by design (or lack of, if you will). You are right in part, the crazy_linker does resolve some of such issues (but not all of them). There is an easy but ugly workaround. Build a dummy libfcn_defined.so which only has T someMethod in its nm. Use it to link libfnc_undefined.so, using LD_LIBS. NDK will show a warning, but that's OK. LAoad the real libfcn_defined.so in your Java.

2686876 0 How does the same origin policy apply to IP addresses

I have a server on our company intranet that runs JBoss. I want to send API calls to this server from my machine, also on the intranet, and get the resulting XML responses using JQuery.

I read the entry on Wikipedia but am confused how that applies to my situation, since our machines only have IP addresses, not domain names.

I have

server URL: 10.2.200.3:8001/serviceroot/service
client IP address: 10.2.201.217

My questions are:

As far as I understand these are different domains, right? So I have to use a proxy to issue JQuery.ajax calls to the server
If I want to avoid doing (2), can I install Apache on the server and server the page with JS code form there? But then the JS will be from 10.2.200.3 and the server is at 10.2.200.3:8001. Aren't these considered different domains according to policy?

Thanks!

35317573 0 counts iteration in a nest for-loop

Here is the pseudo code:

for i=1 to n for j=1 to n for k=1 to j x = x+1

and I have to calculate these two thing (i) count it precisely (ii) find it big-O

in (i), my final answer is n^4+2n^3+5n^2+4n+2. in (ii), because there are three loop, so it's O(n^3);

It seem that there must be an error either (i) or (ii) since (i) raise to the power 4, and the big-O is just 3.

Here is my step when counting the iteration:

for(i=1; i <=n; i++)

count as 1+(n+1)+n which is (2n+2).

So, (2n+2)+n(2n+2)+n(4+6+8+...+2n+2)+n^2(1+2+3+...+n)(2) which finally come out with n^4(see the last term, sum of AS * n).

This $dbh is unset so it becomes $this->null->beginTransaction().
beginTransaction() returns a bool so $stmt becomes bool not PDOStatement

$stmt=$this->$dbh->beginTransaction();

Should probably be something like

$this->dbh->beginTransaction(); $sql = ... $stmt = $this->dbh->prepare($sql);

Replace ... with your insert query.

You don't need transactions for just one query.

You could have Previous/Next buttons quite easily. I would place them outside the TabControl (so you're not duplicating them) and then have their handlers simply increment or decrement the SelectedIndex property of the TabControl.

EDIT: Are you aware that you can make tabs not look like tabs? You can set the Appearance property to TabAppearance.Buttons, for instance, and the "tabs" will instead be rendered as buttons, which would make the tab row look more like a breadcrumb control.

You can also use Panels overlapped on the Form, and call the BringToFront() method of the Panel representing the Page you want.

24300429 0

You can use .closest() to find parent then check its length

29265555 0 managed_file form element doesn't render correctly

I have a simple managed file form element that is the only element in my form. It looks like this:

$form['upload'] = array( '#type' => 'managed_file', '#title' => t('Select a YML file'), '#progress_message' => t('Please wait...'), '#progress_indicator' => 'bar', '#description' => t('Click "Browse..." to select a file to upload.'), '#required' => TRUE, '#upload_validators' => array('file_validate_extensions' => array('yml txt docx')), '#upload_location' => $upload_dest, );

When I render the form using the drupal_get_form callback in hook_menu I get a perfectly formed managed_file upload field with the browse and upload buttons. Things change when I decide I want to add a table of information underneath the form. This requires building a table using theme functions then adding that to the form by rendering the form and appending the table. I create my table and add it to the form:

$rows = array(); foreach($yml_files as $yml_file){ $rows[] = array($yml_file->uri, $yml_file->filename); } $output = drupal_render($form['upload']); $output .= theme('table', array('header'=>$header, 'rows'=>$rows)); return $output;

When I generate the form using drupal_render, I get the nice help text, but no upload form. The table renders fine in both scenarios and I'm not seeing any errors.

If Drupal uses drupal_render to render its forms why would the form look different in the second scnenario? Is there a way to get the entire form? I've tried a variety of ways of passing the form and using dpm to print the form at various stages and I'm not sure where to go from here.

Standard file upload fields render correctly as do other form elements. It seems to be limited to the managed_file element.

To unit test a code, that piece of code needs to be testable.

To unit test a method, what we do is pass in some known input and check it is returning expected result or if we are having correct side effect.

Now if you directly take your input inside your method, it is not very testable. It has two parts, reading the input and processing it. If the assert in your test fails, you don't know which step failed. Unit test should be aimed towards testing a unit or single responsibilty of a code.

To make it testable, read the input in main method and pass it to another method for processing (also common notion of object oriented programming), and test the second method with known parameters.

Yes, it does. The javadoc says:

Closes this input stream and releases any system resources associated with the stream.

And the wrapped stream is definitely such a system resource.

Moreover, GZIPInputStream is a FilterInputStream, and the FilterInputStream javadoc says:

Closes this input stream and releases any system resources associated with the stream. This method simply performs in.close().

A quick google search shows a long record of problems.

They did however made good impression at first but now we're simply not sure - they don't seem to be stable!

22764343 0 Javascript not drawing on canvas

Over here, I am trying to paint image on a canvas (the image is a tile sheet). However, I have checked, the loop works just fine, the code is being executed, the cases are correct (I tested it by logging text to console) however, nothing is being painted on the console.

I think your approach is fine, it gets the job done.

I'm not too sure what you're asking by saying how should you loop the two output statements, followed by if it should be in the main method. From what I understand, and by looking at your code, running this input loop is perfectly fine from the main class. The do-while is fine although I'd move the first 'introductory' output outside the loop so you don't see it every time the loop reiterates. Also, I notice you're not actually calling/instantiating the Store class in your main method, there's no data being added to the Store class for when it iterates through the accounts ArrayList.

As far as the answer that stated a more "modern" approach, I think the for loop you used is fine. I think the person was referring to the for-each loop. It doesn't really matter how you loop through it with the little amount of data you have.

There's some error in the logic for that loop. The getHighestCustomerTotal() is referencing an empty accounts ArrayList. You declared an ArrayList within the Store class and tried to loop through it but it's empty unless you called the addAccount() method from your main method at some point, so you'd need some error checking on that.

31406320 0 Modal window with Angular (UI-Router / Directive)

I have spent some time now looking into a generic way of controlling a modal window with AngularJS and none of the proposed options are anywhere near 'good' solution.

The Directive Solution

I found this demo, however the downside of that is you have to manually manage and store the state of the modal and cross-scope update it:

scope.$parent[attrs.visible] = true;

Also if you had to add more functionality like actually adding an item with a popup that would involve even more ugly code on the parent page scope.

The UI-Router Solution

This is the official guide on how to use modals with ui router.

This however is using ui.bootstrap.modal

My question is, is there any simple and elegant solution to what is quite frankly a very simple problem...

Something like this for example:

.state('popup', { url: '/item/add/', views: { 'popupView': { templateUrl: "/myPopup.html", controller: "myPopupController" } }, type: 'modal' })

And things like close, redirect, submit, all are handled in the myPopupController.

I am not seeking an explanation of why the examples are above are as they are, or how I should be using them. I am simply looking if anyone has come up with a better solution.

marcos is right, but you have a couple other options as well. First of all, there is an either/or:

assertThat(result, either(is(1)).or(is(2)));

but if you have more than two items it would probably get unwieldy. Plus, the typechecker gets weird on stuff like that sometimes. For your case, you could do:

assertThat(result, isOneOf(1, 2, 3))

or if you already have your options in an array/Collection:

assertThat(result, isIn(theCollection))

No

Is the simple answer, you have to extend CIs functionality and use a library from a third party to provide these features for you. CI doesn't focus on the aesthetics of the "front-end". Its primary focus was "back-end".

Your Options:

look into Phil Sturgeons template library, and CI Sprinkles library first is for layout/theme/partials management, second is for asset management js/css minification and caching.

Phil's Template Library: http://philsturgeon.co.uk/demos/codeigniter-template/user_guide/

Sprinkles Library: https://github.com/edmundask/Sprinkle

Or build your own basic template library

This is a great intro video how to do such. I have used this in the past, before i got into using Sparks. http://www.youtube.com/watch?v=gvGymDhY49E

you can use Sparks to make lib management a bit easier

In 2.1 sparks aren't included however it is in the dev builds of CI so im sure at a later date it will be merged in with the base code. FOr now you can use this site to install Sparks to help you manage third party libraries.

$a == $b Equal TRUE if $a is equal to $b after type juggling. $a === $b Identical TRUE if $a is equal to $b, and they are of the same type.

it looks that

if you check 0 against a string with == then PHP returns true:

php -r 'var_dump(0 == "statuses");' -> returns TRUE

but not if your string has a number at the beginning:

php -r 'var_dump(0 == "2statuses");' -> returns FALSE

from the specs I get it that it attempts a conversion - in this case the string to number.

so better use ===

 [AllowAnonymous] public ActionResult ForgotPassword(string id) { var model = new ForgotPasswordViewModel(); if (!string.IsNullOrEmpty(id)) { #region Process Reset Password Key try { var forgotPasswordEvent = AppModel.ForgotPasswordEvents.SingleOrDefault(x => x.UIDHash == id); if (forgotPasswordEvent != null) { var stringToHash = string.Format("{0}---{1}---{2}", forgotPasswordEvent.UID.ToString(), forgotPasswordEvent.UserId.ToString(), forgotPasswordEvent.Created.ToString()); var readyHash = SecurityHelper.GetHashString(stringToHash); if (id == readyHash) { var forgotPasswordEventUserId = forgotPasswordEvent.UserId.ToString(); var realUser = AppModel.AspNetUsers.SingleOrDefault(x => x.Id == forgotPasswordEventUserId); if (realUser != null) { var resetPasswordViewModel = new ResetPasswordViewModel(); resetPasswordViewModel.ResetPasswordData = id; resetPasswordViewModel.UserName = realUser.UserName; return RedirectToAction("ResetPassword", "Account", resetPasswordViewModel); // ResetPassword(resetPasswordViewModel); } } } else { return RedirectToAction("Index", "Home"); } } catch (Exception) { } #endregion } #region Check if the user is logged in and fill out fileds for him. var sessionManager = SessionWrapper.GetFromSession<SessionManager>("_SessionManager"); if (sessionManager != null) { var clientId = sessionManager.AppUser.ClientId; if (clientId != null) { model.Email = sessionManager.AppUser.EmailID; model.UserName = sessionManager.AppUser.UserName; model.IsLoggedInUser = true; } } #endregion return View(model); } [HttpPost] [AllowAnonymous] public ActionResult ForgotPassword(ForgotPasswordViewModel model, FormCollection formCollection) { if (ModelState.IsValid) { try { #region Check user input var user = AppModel.AspNetUsers.SingleOrDefault(x => x.UserName == model.UserName); var areErrors = false; if (user == null) { ModelState.AddModelError("UserDoesnotExist", DLMModelEntities.Properties.Resource.UserDoesNotExist); areErrors = true; } if (user.EmailID != model.Email) { ModelState.AddModelError("EmailIsWrong", DLMModelEntities.Properties.Resource.EmailIsWrong); areErrors = true; } if (areErrors) return View(model); #endregion #region Send Email and inform user try { var forgotPasswordEvent = new ForgotPasswordEvent(); var resetPasswordEmailUserState = new ResetPasswordEmailUserState(); resetPasswordEmailUserState.ForgotPasswordEventId = Guid.NewGuid(); resetPasswordEmailUserState.UserId = Guid.Parse(user.Id); resetPasswordEmailUserState.Created = DateTime.Now; forgotPasswordEvent.UID = resetPasswordEmailUserState.ForgotPasswordEventId; forgotPasswordEvent.UserId = resetPasswordEmailUserState.UserId; forgotPasswordEvent.IsSent = false; forgotPasswordEvent.Created = resetPasswordEmailUserState.Created; var stringToHash = string.Format("{0}---{1}---{2}", resetPasswordEmailUserState.ForgotPasswordEventId.ToString(), resetPasswordEmailUserState.UserId.ToString(), resetPasswordEmailUserState.Created.ToString()); forgotPasswordEvent.UIDHash = SecurityHelper.GetHashString(stringToHash); AppModel.ForgotPasswordEvents.Add(forgotPasswordEvent); AppModel.SaveChanges(); var smtp = (SmtpSection)ConfigurationManager.GetSection("system.net/mailSettings/smtp"); // Set the MailerModel properties that will be passed to the MvcMailer object. var m = new MailerModel(); m.UserName = user.UserName; m.ResetPasswordLink = string.Format("{0}/{1}", Request.Url.AbsoluteUri, forgotPasswordEvent.UIDHash); m.FromEmail = smtp.From; m.Subject = AppConfiguration.ResetEmailSubject; m.ToEmail = model.Email; var client = new SmtpClientWrapper(); client.SendCompleted += (sender, e) => { if (e.Error != null || e.Cancelled) { // Handle Error } else { try { var forgotPasswordEventsToUpdate = AppModel.ForgotPasswordEvents.SingleOrDefault(x => x.UID == resetPasswordEmailUserState.ForgotPasswordEventId); if (forgotPasswordEventsToUpdate != null) { forgotPasswordEventsToUpdate.IsSent = true; AppModel.SaveChanges(); } } catch (Exception ex) { ModelState.AddModelError("EmailEx", ex.Message); } } }; Mailer.PasswordReset(m).SendAsync(resetPasswordEmailUserState, client); model.IsResetEMailSent = true; } catch (Exception ex) { ModelState.AddModelError("EmailEx", ex.Message); } #endregion } catch (Exception ex) { ModelState.AddModelError("EmailEx", ex.Message); } } return View(model); }

assuming you are using rake to apply an active record migration. The file path will be relative to where you started rake which I'm sure will be the projects root.

The file path would be:

content = File.read("app/views/layouts/application.html.erb")

Let's say you want to keep track of a collection of stuff. Said collections must support a bunch of things, like adding and removing items, and checking if an item is in the collection.

You could then specify an interface ICollection with the methods add(), remove() and contains().

Code that doesn't need to know what kind of collection (List, Array, Hash-table, Red-black tree, etc) could accept objects that implemented the interface and work with them without knowing their actual type.

18645609 0 Can't get eclipse to start after a computer crash

I am running eclipse in a virtual machine. The vm ran out of memory so it had to shut down. Now when I try to start eclipse, nothing happens. A process starts in the task manager but it hardly is holding any memory and no windows pop up, simply nothing happens. Here is the log file in .metadata

Log: !ENTRY org.eclipse.core.resources 2 10035 2013-09-05 14:49:58.989 !MESSAGE The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes. !ENTRY org.eclipse.egit.ui 2 0 2013-09-05 14:50:14.848 !SESSION 2013-09-05 15:03:21.108 ----------------------------------------------- eclipse.buildId=M20130204-1200 java.version=1.6.0_45 java.vendor=Sun Microsystems Inc.

If you have a populated select widget, for example:

<select> <option value="1">one</option> <option value="2" selected="selected">two</option> <option value="3">three</option> ...

you will want to convince select2 to restore the originally selected value on reset, similar to how a native form works. To achieve this, first reset the native form and then update select2:

$('button[type="reset"]').click(function(event) { // Make sure we reset the native form first event.preventDefault(); $(this).closest('form').get(0).reset(); // And then update select2 to match $('#d').select2('val', $('#d').find(':selected').val()); }

You haven't put the shared library in a location where the loader can find it. look inside the /usr/local/opencv and /usr/local/opencv2 folders and see if either of them contains any shared libraries (files beginning in lib and usually ending in .so). when you find them, create a file called /etc/ld.so.conf.d/opencv.conf and write to it the paths to the folders where the libraries are stored, one per line. Then run

sudo ldconfig -v

for example, if the libraries were stored under /usr/local/opencv/libopencv_core.so.2.4 then I would write this to my opencv.conf file:

/usr/local/opencv/

If you can't find the libraries, try running

sudo updatedb && locate libopencv_core.so.2.4

in a shell. You don't need to run updatedb if you've rebooted since compiling OpenCV.

It sounds like you've defined the copy constructor without defining any other constructor.

Once you declare an constructor explicitly, the compiler no longer provides a default constructor for you. Consequently, you no longer have a mechanism to construct an object of the class in the first place (and therefore wouldn't be able to copy it).

Other answers pointing to the fact that Strings are immutable are accurate.

But if you want to have the functionality of "clearing a String", you can use a StringBuffer instead and call this on it:

stringBuffer.delete(0, stringBuffer.length());

By using this package https://sublime.wbond.net/packages/RegReplace you can create regex patterns and bind them to shortcuts.

Also if there are multiple occurrences of one word, you can put cursor on whatever part of the word and press CTRL+D multiple times. One CTRL+D press will select the word under the cursor, every other press will select next occurrence of the word.

You could also use https://sublime.wbond.net/packages/Expand%20Selection%20to%20Whitespace to expand the selection to whitespace if your word contain some random characters, and then press CTDL+D to select next occurrences of the word.

Edit: With the package regex shortcuts indeed you have to create regexes before binding them. But the CTRL+D does work without it. I don't see a problem with using "Expand selection to whitespace" and than doing the CTRL+D as I wrote in the answer.

I've checked the usage of visual as you wrote in the question and this solution seems much faster to do. You don't have to place cursor in the beggining of the word as It can be whereever in the word and no find/replace is needed, since you'll multiselect all occurrences by holding CTRL+D for a sec and You'll be free to edit it.

You can also use https://sublime.wbond.net/packages/Expand%20Selection%20to%20Quotes to select text inside quote and combine it with CTRL+D if standard CTRL+D doesn't work with some text, or if select to whitespace selects too much text.

When you open the exported data file directly with Excel, all formats are set as General. In General format, Excel applies formatting to what it recognizes as numbers and dates. So, to be clear, the issue is not with your export, but rather with how Excel is reading your data by default. Try the following to get around this issue.

Export to CSV. Then, rather than opening the CSV in Excel, use Excel's 'Get External Data From Text' tool to import the data into an empty workbook. Here you can specify to treat this field as TEXT rather than as GENERAL.

Note that once Excel applies number (or date) format to a cell, the data in the cell has been changed. No application of a new format will bring back your desired data. For this reason you must specify the format before Excel opens the file.

28779170 0 Writing jQuery in separte files to support concatenation in production

For now I have written my .js files as followed because I think, this is simple for maintenance.

//main.js $(function() { //declare variables, functions }); //page1.js $(function() { //whatever for page1 }); //page2.js $(function() { //whatever for page2 });

In .html I just have to specify which .js files to load, this is working so far because the individual .html is assigned with the right .js files

<!-- page1.html --> <script src="main.js"> <script src="page1.js"> <!-- page2.html --> <script src="main.js"> <script src="page2.js">

If I plan to concatenate all .js files into one single .js file for production purpose, how should i restructure my .js files to support concatenation so in each .html i can only use <script src="all.js">

Please guide what to do. Thanks.

I believe aerospike would serves your purpose, you can configure it for hybrid storage at namespace(i.e. DB) level in aerospike.conf which is present at /etc/aerospike/aerospike.conf

Not sue why you would need to do this but you can use identical to do the comparison. However, since identical only compares two arguments, you will have to loop over your list, preferably using lapply...

lapply( a , function(x) identical( substitute(1 + 2) , x ) ) #[[1]] #[1] TRUE #[[2]] #[1] FALSE

Or similarly you can still use ==. Inspection of substitute(1 + 2) reveals it to be a language object of length 3, whilst your list a is obviously of length 2, hence the warning on vector recycling. Therefore you just need to loop over the elements in your list which you can do thus:

lapply( a , `==` , substitute(1 + 2) ) #[[1]] #[1] TRUE #[[2]] #[1] FALSE

13409129 0 Which loops and which co-ordinate system can I use to automate this example of a truss structure

I am completely new to matlab and can't seem to get an if loop to work. For example if Ln > k , plot point i(n-1) to i(n). How would I automatically assign the correct row or column vectors to i(n)?

Here is a diagram of what I'm wanting

enter image description here

What I want to achieve is connect i(0) to i(1) to ... i(n-1) to i(n).

I also am a bit confused at which co-ordinate system to use? I thought it would be easy to use a polar co-ordinate system. Defining a distance and angle from point i(o) and then doing the same from point i(1) but from what I could find, it is necessary to convert back to a cartesian co-ordinate system.

Once I am comfortable with this section I am confident I can take on the next steps, and develop a full solution to my problem. If you are interested in what I am trying to achieve, here's a link

[PLEASE NOTE] In that question I linked to, I was told I made a mess of it. I'm sorry if this question is also not clear. I really have spent the time to make it as clear as possible. I find it hard to express myself sometimes.

743094 0 App_Data/ASPNETDB.MDF to Sql Server 2005 (or 08)

I've been developing an ASP.NET WebForms app that needed account login functionality (e.g. register new users, change passwords, recover passwords, profiles, roles, etc). To do this, I used FormsAuthentication with the default data store, which, to my surprise, is an MDF file in App_Data. When it comes time to actually deploy this app. live on the web, I'm going to use some shared hosting like GoDaddy or another cheap company.

For efficiency, I'd like to switch over from this MDF to actual SQL Server 2005 or 2008 (who in their right mind uses flat files?). With shared hosting, however, I'm not going to be able to run any programs like aspnet_regsql.exe. I'll just have a single login and password to a SQL Server database, and an FTP account into the domain root. No MSTSC remote desktop, no console access, no tinkering in IIS, etc.

I won't need to transfer any user accounts from ASPNETDB.MDF (site will be starting with zero users), but how am I suppose to:

1) Easily create the tables, procedures, etc. that Visual Studio automatically created in ASPNETDB.MDF when I used Web Site Administration Tool to get started with FormsAuthentication?

2) Have the SQL membership provider use a connection string I give it instead of using whatever it is now to connect to this ASPNETDB.MDF. Hell, I don't even see any connection string to this MDF in the web.config; how the hell is my app. even finding it? Machine.config? That would be a poor decision if that's the case. This behind-the-scenes crap drives me nuts.

Any help from someone who has been through this migration would be very, very much appreciated!

20477511 0 createjs load local files loadqueue

Im have been working on a project with the createjs library and I have used Brackets with Live preview where everything works perfectly, but if I just open the file in a browser I get the following error message in chrome.

XMLHttpRequest cannot load file:///C:/Users/Maskinen/Docuemnts/fail.fail. Cross origin requests are only supported for HTTP.

I have read that if I set loadqueue(false) I wouldnt get problems with loading local files. I therefore thought that when it was working in live preview in brackets everything was fine. Is it possible to run chrome or firefox as Brackets in live preview or similar? The project is part of an assignment and it isnt possible to use a webserver :(

10727481 0 Determine Cobol coding style

I'm developing an application that parses Cobol programs. In these programs some respect the traditional coding style (programm text from column 8 to 72), and some are newer and don't follow this style.

In my application I need to determine the coding style in order to know if I should parse content after column 72.

I've been able to determine if the program start at column 1 or 8, but prog that start at column 1 can also follow the rule of comments after column 72.

So I'm trying to find rules that will allow me to determine if texts after column 72 are comments or valid code.

I've find some but it's hard to tell if it will work everytime :

dot after column 72, determine the end of sentence but I fear that dot can be in comments too
find the close character of a statement after column 72 : " ' ) }
look for char at columns 71 - 72 - 73, if there is not space then find the whole word, and check if it's a key word or a var. Problem, it can be a var from a COPY or a replacement etc...

I'd like to know what do you think of these rules and if you have any ideas to help me determine the coding style of a Cobol program.

I don't need an API or something just solid rules that I will be able to rely on.

Isn't what you want to implement the scanl1 function? I'm a beginner too, but from what I understood, it goes like this:

scanl1 :: (a -> a -> a) -> [a] -> [a] scanl1 f (x:xs) = scanl f x xs scanl1 _ [] = []

The scanl function. which scanl1 uses, goes like this:

scanl :: (b -> a -> b) -> b -> [a] -> [b] scanl = scanlGo where scanlGo :: (b -> a -> b) -> b -> [a] -> [b] scanlGo f q ls = q : (case ls of [] -> [] x:xs -> scanlGo f (f q x) xs)

Here's what hackage has to say about scanl:

scanl :: (b -> a -> b) -> b -> [a] -> [b] Source

scanl is similar to foldl, but returns a list of successive reduced values from the left:

scanl f z [x1, x2, ...] == [z, z `f` x1, (z `f` x1) `f` x2, ...]

Note that

last (scanl f z xs) == foldl f z xs.

So, I guess the flow of execution goes like this:

scanl1 (+) [2, 4, 1, 1] scanl (+) 2 [4, 1, 1] scanlGo (+) 2 [4, 1, 1] 2 : scanlGo (+) (+ 2 4) [1, 1] 2 : 6 : scanlGo (+) (+ 6 1] [1] 2 : 6 : 7 : scanlGo (+) (+ 7 1) [] 2 : 6 : 7 : 8 : scanlGo [] 2 : 6 : 7 : 8 : [] [2, 6, 7, 8]

The same thing happens with the (*) and the max functions that you mentioned. Hope this helps.

At the very end, all my code in the callback is working on the ajax added images itself. I need to calculate the height of the inner div but i always get '0' because the images haven't been added yet. How do it do that?

You have to do this with values() but restrict fields that you want to group by

Core.objects.values('age_id', 'cat_id').filter(state='ABC').annotate(Max('date'), Count('age_id', 'cat_id'))

25567424 0

The maxElements could be a limit for the list. You can use x.size() > 0 check if you want x.get(0).

ArrayList<Points> x = new ArrayList<>(); for (int i = 0; i < maxElements; i++) { x.add(new Point(0, 0)); } Points p; if (x.size() > 0) p = x.get(0);

I would go with a different approach (though yours is not wrong in any way but I think is less common):

Let the status be part of HTTP header with an HTTP return code (200, 201, ..., 400, 404, ..., etc.) and in the case you mentioned, an JSON array instead of the result field: [{...}, ...]

A simple example:

Request:

GET /api/v1/users HTTP/1.1

Response:

200 OK Content-Type: application/json Date: Sun, 07 Sep 2014 15:24:04 GMT Content-Length: 261 .... [ { "username": ..., "email": ..., "firstName": ..., "lastName": ..., "password": ..., ... }, { "username": ..., "email": ..., "firstName": ..., "lastName": ..., "password": ..., ... } ]

As @user488074 said, your controller must have an argument that it is looking for when you create an instance of it. Go to that controller and look at what it is looking for in the contstruct function. If you don't want to pass an argument all the time for this controller then add something like this to the construct function argument

public function foo($argument = NULL){ }

so it has a default value if you don't want to pass something.

The question is a bit old, but maybe this can be useful for someone with the same issue.

Here is a simple example from the code I used:

On my controller, I generate a markers array with this structure:

 var markers = new Array(); for(var i = 0; i < someData.length; i++ ){ var newMarker = { id: parseInt(i), latitude: parseFloat(someData[i].latitude), longitude: parseFloat(someData[i].longitude), showWindow: false, title: "Marker"+i, } newMarker.onClicked = function () { alert(newMarker.id); } markers.push(newMarker); } $scope.markers = markers;

Then on the view:

<google-map center="map.center" draggable="true" options=map.options zoom="map.zoom"> <markers models="markers" coords="'self'" doCluster=true click="'onClicked'"> </markers> </google-map>

Okay, given the DCOS template, the LaunchConfiguration for the slaves looks like this: (I've shortened it somewhat)

"MasterLaunchConfig": { "Type": "AWS::AutoScaling::LaunchConfiguration", "Properties": { "IamInstanceProfile": { "Ref": "MasterInstanceProfile" }, "SecurityGroups": [ ... ], "ImageId": { ... }, "InstanceType": { ... }, "KeyName": { "Ref": "KeyName" }, "UserData": { ... } } }

To get started, all you need to do is add the SpotPrice property in there. The value of SpotPrice is, obviously, the maximum price you want to pay. You'll probably need to do more work around autoscaling, especially with alarms and time of day. So here's your new LaunchConfiguration with a spot price of $1.00 per hour:

"MasterLaunchConfig": { "Type": "AWS::AutoScaling::LaunchConfiguration", "Properties": { "IamInstanceProfile": { "Ref": "MasterInstanceProfile" }, "SecurityGroups": [ ... ], "ImageId": { ... }, "InstanceType": { ... }, "KeyName": { "Ref": "KeyName" }, "UserData": { ... }, "SpotPrice": 1.00 } }

You should to init needed layout messages through Mage_Core_Controller_Varien_Action::_initLayoutMessages()

Example:

public function resultAction() { $this->_title($this->__('Printer Applicable Products')); $this ->loadLayout() ->_initLayoutMessages('checkout/session') ->_initLayoutMessages('catalog/session') $this->renderLayout(); }

You need to init a session model that contains needed messages.

Also keep in mind that printer/finder/result.phtml should contain

$this->getMessagesBlock()->getGroupedHtml()

206751 0 MySQL autoincrement column jumps by 10- why?

I have a couple tables in which I created an object ID as either an Int or Bigint, and in both cases, they seem to autoincrement by 10 (ie, the first insert is object ID 1, the second is object ID 11, the third is object ID 21, etc). Two questions:

Why does it do that?
Is that a problem?

Okay, so first of all you will need to implement the MouseListener interface. You can either have your main class implement MouseListener, or attach a generic implementation to a JPanel via addMouseListener(). The latter method is described below:

public class MyPanel extends JPanel { public MyPanel() { // ... this.addMouseListener(new MouseListener() { @Override public void mouseClicked(MouseEvent e) { if (e.getButton() == MouseEvent.BUTTON1) { // Handle left-click } else if (e.getButton() == MouseEvent.BUTTON2) { // Handle right-click } } }); } }

You can also check e.isShiftDown() to see if the Shift key is being held.

10925210 0 How can I conditionally suppress logging in Express (or Connect)?

When using the logger middleware which is part of Connect (as well as Express), I would like to be able to disable logging on certain requests, say by setting a flag on the response or something.

I managed to do it by saying:

res.doNotLog = true;

and then, deep in logger.js (part of the Connect module), I put

if(res.doNotLog) return;

in the right place. But of course I don't want to be modifying code in the module itself. Is there any way I can cause the same to happen without having to hack the module?

Edit:

This worked:

var app = _express.createServer(); // set 'hello' routing...note that this is before middleware // so it won't be logged app.get('/sayhello', function(req, res) {res.send("hey");}); // configure middleware: logging, static file serving app.configure(function() { app.use(_express.logger()); app.use(_express.static(__dirname + '/www')); }); // set 'goodbye' routing...note that this is after middleware // so it will be logged app.get('/saygoodbye', function(req, res) {res.send("later...");});

Add the namespace to your class file. using System.Net.Mail;
Provide arguments when you call the function (SendMailMessage).
Make class SendMail as a static class, SendMailMessage as static function.

Tom,

I too have been experiencing issues with Sql CE and the Entity Framework. BUT, I may be able to explain the post that you are referencing because I am versed in using it now that I have fought my way through it.

For starters, that blog entry was for the MVCScaffolding NuGet package. Not sure if you know what this package does but it basically adds a reference to the Scaffolder that Scott & Company created to dynamically generate CRUD for you once you have built your models.

My understanding is that once you create a model, build your project, you can run the following command in the Package Manager Console and it will create the CRUD that I mentioned above.

Scaffold Controller [WhateverYourModelNameIs]

Now, once this process is complete, it generates a Context class for your application under the Models folder. If you see above in your code (for SQLCEEntityFramework.cs) in the Start method, it mentions that you need to uncomment the last line of the method in order for it to create the db if it does not exist.

Lastly, once you execute your application, a SQL CE database "should" be created and if you click on the App_Data folder and choose to 'Show All Files' at the top of the Solution Explorer and hit the Refresh icon, you should see your database.

UPDATE:

So sorry, after testing this, Tom, you are correct. Only way the database is created is if you execute one of the views that were created by the Scaffolder.

I was wondering what the equivalent of this is for .NET (Unity uses .NET 2.0)?

I know it's possible to call functions in an Objective-C++ file from unity but I need a way to do this on any platform not just iOS.

Youd need to pad your data with at least order n zeros; then you could set stride[n]==-stride[m] to achieve the intended effect, and avoid allocating order n*m zeros.

But something tells me there must be a more elegant solution to your problem, if you take a bigger-picture view.

The issue is that your app does not have a module named uwsgi. You change the directory to /home/user/appname but it looks like the actual module would be appname.uwsgi since the uwsgi.py file lives within /home/user/appname/appname/uwsgi.py.

Typically though, you don't need to specify both --wsgi-file and --module so I would either do

uwsgi --http :9010 --chdir /home/user/appname --wsgi-file /home/user/appname/appname/wsgi.py

uwsgi --http :9010 --chdir /home/user/appname --module appname.uwsgi

I personally prefer the second.

20890855 0 Adding a ContactsContract.CommonDataKinds.Event to Android contacts, does not show up

I'm trying to add a birthday event to contacts but the event doesn't show up when displaying the contact in the People app. When going into 'Edit' mode of the contact, an event DOES show up, but no selected date (see attached screenshot) as if the format is wrong.

When inspecting the contacts2.db in an sqlite viewer, it seems that the date are formatted just fine, like other events/birthdays that are properly showing (see attached image. First row is a manually entered birthday through the app, and the second row, was added by my app and doesn't show)

Here is the code I am using, which follows the SampleSyncAdapter from the $ANDROID_HOME sdk

public ContactOperations addBirthday(Date date) { mValues.clear(); if(date!=null) { mValues.put(ContactsContract.CommonDataKinds.Event.TYPE, ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY); mValues.put(ContactsContract.CommonDataKinds.Event.START_DATE, BIRTHDATE_FORMATTER.format(date)); mValues.put(ContactsContract.CommonDataKinds.Event.MIMETYPE, ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE); addInsertOp(); } return this; } private void addInsertOp() { if (!mIsNewContact) { mValues.put(ContactsContract.CommonDataKinds.Phone.RAW_CONTACT_ID, mRawContactId); } ContentProviderOperation.Builder builder = newInsertCpo(ContactsContract.Data.CONTENT_URI, mIsSyncOperation, mIsYieldAllowed); builder.withValues(mValues); if (mIsNewContact) { builder.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, mBackReference); } mIsYieldAllowed = false; mBatchOperation.add(builder.build()); }

how about that:

value = value > 0 ? value: ~value + 1

its based on the fact that negative numbers are stored as 2's complement to there positive equivalent, and that one can build the 2's complement by first building the 1's complement and adding 1, so

 5 -> 0000 0101b -5 -> (1111 1010b) + 1 -> 1111 1011b

what I did was basically to reverse this, so

-5 -> 1111 1011b 5 -> (0000 0100b) + 1 -> 0000 0101b

I know it's a bit late but just had the same issue and landed here, hope this helps.

In front i have shown record is deleted.

But if he want to add the record with that deleted id. Primary key voilation error from my database.when he insert the record.

Thanks

When you define operators like operator- inside your class as member functions, then when you use it

C3 = C1 + C2;

The compiler is actually calling your member function like

C3 = C1.operator+(C2);

From this you should be able to figure out that operators as member functions only takes one argument, and that the first object in the operator is the this object.

For stand-alone (non-member) functions they need two arguments.

You might want to check e.g. this reference on operator overloading.

21709561 0 How get Admin credentials? I am the Admin already

My new computer have Windows 8.1 64-bit Spanish version; the previous one had Windows XP and I never messed before with Credentials, Privileges, etc. In my computer there is just one user account that is marked as Administrator: "They have access to all files and programs stored in the computer". However, if I open a command-line window and execute chkdsk I get this:

Microsoft Windows [Versión 6.2.9200] (c) 2012 Microsoft Corporation. Todos los derechos reservados. C:\Users\Antonio> chkdsk Acceso denegado porque no tiene privilegios suficientes. Invoque esta utilidad ejecutándola en modo elevado.

That is: "Access denied because you have not enough privileges. Invoke this utility executing it in elevated mode". I tried to use runas command, but I don't understand what parameters I must give.

I get the same result when I execute fsutil with these options:

C:\Users\Antonio> fsutil fsinfo ntfsInfo C: Error: Acceso denegado.

How can I execute these programs in my computer? TIA

If you can't find a method, you can build one using ruby's include? method.

Official documentation: http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-include-3F

Usage:

array = [1, 2, 3, 4] array.include? 3 #=> true

Then, you can do a loop:

def array_includes_all?( array, comparision_array ) contains = true for i in comparision_array do unless array.include? i contains = false end end return contains end array_includes_all?( [1,2,3,2], [1,2,2] ) #=> true

If you only need to find direct members, you can use Attribute Scope Query (ASQ). This requires domain/forest functional level of 2003 (forgot domain or forest).

DirectoryEntry groupEntry = new DirectoryEntry("LDAP://<server>/<group DN>", "user", "pwd"); DirectorySearcher searcher = new DirectorySearcher(groupEntry); searcher.SearchScope = SearchScope.Base; searcher.AttributeScopeQuery = "member"; searcher.Filter = "(&(objectCategory=person)(objectClass=user))"; searcher.PropertiesToLoad.Clear(); searcher.PropertiesToLoad.Add("name"); searcher.PropertiesToLoad.Add("mail"); searcher.PropertiesToLoad.Add("displayName"); foreach (SearchResult result in searcher.FindAll()) { Console.WriteLine(result.Path); }

For nested group members, you may use the LDAP_MATCHING_RULE_IN_CHAIN matching rule. This requires domain/forest functional level of 2008 R2 (again, forgot domain or forest).

DirectoryEntry rootEntry = new DirectoryEntry("GC://<server>", "user", "pwd"); DirectorySearcher searcher = new DirectorySearcher(rootEntry); searcher.SearchScope = SearchScope.Subtree; searcher.Filter = "(&(objectCategory=person)(objectClass=user)(memberOf:1.2.840.113556.1.4.1941:=<group DN>))"; searcher.PropertiesToLoad.Clear(); searcher.PropertiesToLoad.Add("name"); searcher.PropertiesToLoad.Add("mail"); searcher.PropertiesToLoad.Add("displayName"); foreach (SearchResult result in searcher.FindAll()) { Console.WriteLine(result.Path); }

Limitations:

Both methods don't handle primary group membership
ASQ don't work across domain, an exception will be thrown if member from another domain is found. So normally you can only perform this for global groups.

33733533 0 How configure fsync for specific command in redis

I try to find about custom AOF configuration. I found only that:

There are three options:

fsync every time a new command is appended to the AOF. Very very slow, very safe.

fsync every second. Fast enough (in 2.4 likely to be as fast as snapshotting), and you can lose 1 second of data if there is a disaster.

Never fsync, just put your data in the hands of the Operating System. The faster and less safe method.

Can I configure fsync which every time append a command to the AOF only for specific command (INCR)? Is it possible ?

Windows Azure machines are yours for the using so if you want a different time zone, go right ahead and set it.

The easiest approach is to create a very simple startup task and use tzutil, the Windows Time Zone Utility. We use the following:

tzutil /s "GMT Standard Time"

This is installed by default only on the Windows Server 2008 R2 or Windows Server 2012 images.

I have identified a workaround.

I'm using a tuple for the constraint and handling it myself in the didApplyConstraints handler.

The format for the custom constraint assumes that the range begins at the first value and travels counter clockwise until the second value. It makes no allowances for constraint values above PI or below -PI. This solution also doesn't deal with total ranges greater than 2*PI.

Ranges that do not cross the +/- PI boundary are "normal" and can be handled normally.

Ranges that DO cross the +/- PI boundary are "goofy" and must be handled as a special case (if possible).

A solution to the special case seems impossible unless you are tracking angular velocity with an SKPhysicsBody (or manually). This value is required to identify which boundary the node likely "crossed" and should thus be constrained to.

// constraint = (CGFloat(M_PI/2), -CGFloat(M_PI/2)) override func didApplyConstraints() { var r = rotationSprite.zRotation if constraint.0 < constraint.1 { // regular constraint, easy to handle. rotationSprite.zRotation = min(max(r, constraint.0),constraint.1) } else // "goofy" constraint that crosses PI boundary { if r < constraint.0 && r > constraint.1 { if rotationSprite.physicsBody?.angularVelocity < 0 { // clockwise, crossed first value (so long as absolute angular vel is < 2PI rotationSprite.zRotation = constraint.0 } else if rotationSprite.physicsBody?.angularVelocity > 0 // counter clockwise, crossed second value (so long as absolute angular vel is < 2PI { rotationSprite.zRotation = constraint.1 } else { // If 0 velocity (or no velocity), no way to find out which boundary was crossed. rotationSprite.zRotation = constraint.0 // Probably better to default to closest angle } rotationSprite.physicsBody?.angularVelocity = 0 // Alternately, multiply by a negative restitution factor. } } }

40054710 0 Run Breeze Entity Manager in Node

How is everyone else testing their breeze client-side entity functions?

I have entity Ticket that has Tags navigation property with hundreds of Tags.

Each Tag has many boolean properties IsChanged, IsTagged, IsReplaced, etc

Each tag also has an Item navigation property. The Item has ItemType (ItemType is another entity with properties like TestFrequency), IsCondemened, etc

I have functions on the Ticket and Tag and Item entities, that filter, map, and reduce over all the related entities, to summarize all the tags and items for each Ticket.

I need to test these functions, and I'm finding that to create all these objects by hand for my tests is a ton of duplication of code.

If I could just have a json file on disk with some sample entities straight from the database, then not only would it eliminate a bunch of boilerplate factory code, but I could be sure that whenever my data schema changes in EF on server side, my json would also change to reflect that.

Here's where I'm scratching my head:

I need to be able to run breeze-client in node so my npm script can grab the data and save it to disk with one command.

I cannot find ONE complete solution ANYWHERE for using breeze-client in node.

There is another question that asks about it 3 years ago, and no definitive working answer was ever given.

Also this github issue last year, with one comment coming really close to a full answer, but the actual implementation of the adapter was never shared.

With the vast number of people who use the breeze library, I feel like I'm doing something wrong when the only way I can see to reliably test my entities is to run breeze-client in node, and NO ONE ELSE seems interested in running breeze-client in node.

I was trying to figure out how to create an ajaxAdapter myself for node, but I keep striking out.

Please can someone either give me a clue for how to make a node ajaxAdapter, or tell me a better way to be testing my business logic on my breeze entities?

1487194 0 Subclasses causing unexpected behavior in superclasses — OO design question

Although I'm coding in ObjC, This question is intentionally language-agnostic - it should apply to most OO languages

Let's say I have an "Collection" class, and I want to create a "FilteredCollection" that inherits from "Collection". Filters will be set up at object-creation time, and from them on, the class will behave like a "Collection" with the filters applied to its contents.

I do things the obvious way and subclass Collection. I override all the accessors, and think I've done a pretty neat job - my FilteredCollection looks like it should behave just like a Collection, but with objects that are 'in' it that correspond to my filters being filtered out to users. I think I can happily create FilteredCollections and pass them around my program as Collections.

But I come to testing and - oh no - it's not working. Delving into the debugger, I find that it's because the Collection implementation of some methods is calling the overridden FilteredCollection methods (say, for example, there's a "count" method that Collection relies upon when iterating its objects, but now it's getting the filtered count, because I overrode the count method to give the correct external behaviour).

What's wrong here? Why does it feel like some important principles are being violated despite the fact that it also feels like OO 'should' work this way? What's a general solution to this issue? Is there one?

I know, by the way, that a good 'solution' to this problem in particular would be to filter the objects before I put them into the collection, and not have to change Collection at all, but I'm asking a more general question than that - this is just an example. The more general issue is methods in an opaque superclass that rely on the behaviour of other methods that could be changed by subclasses, and what to do in the case that you want to subclass an object to change behaviour like this.

It is a very clear algorithm and seems you got it right. So for changing the way of accessing the characters, why didn't you use the String#charAt method?

Also you may want to change the return type of the method from String "YES" or "NO" to true or false of type boolean:

static boolean isValidBracketString(String string) { Stack<Character> stack = new Stack<>(); for(int i=0; i< string.length(); i++){ if(string.charAt(i) == '{' || string.charAt(i) == '[' || string.charAt(i) == '('){ stack.push(string.charAt(i)); } else if(string.charAt(i) == '}' || string.charAt(i) == '}' || string.charAt(i) == ')') { if(stack.size() == 0) return false; switch(stack.pop()){ case '(': if(string.charAt(i) != ')') return false; break; case '[': if(string.charAt(i) != ']') return false; break; case '{': if(string.charAt(i) != '}') return false; break; } } } return stack.size() == 0; }

23315169 0 How to add NSDictionary to NSArray to use it in tableview

NSDictionary *recipe = arrayOfPlist[i];

that I use it in a for loop

and in a if statement I added this dictionary to an NSArray results= [recipe allValues]; like this

and I segue it like this

 destViewController.filteredContent=results;

I checked it the results array is not null but when I compile it and try to go to a PageView with selected array I'm having this exception

 *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<__NSCFString 0x109268e40> valueForUndefinedKey:]: this class is not key value coding-compliant for the key recipeName.'

RecipeName is a key from my Dictionary which I use it to write to cell.

I couldn't see the problem so I came here.

It turned out that s not my real problem. The crash happened at the next view controller which is a pageViewController. I passed the results array and it should only have 1 elements in it but when i checked it it says the count 8= number of keys in my dictionaries. It added all of the keys as a unique array element and thats where the problem happened. There is really not a recipeName ...

how can i fix this??

<plist version="1.0"> <array> <dict> <key>category</key> <string>desert</string> <key>numberOfPerson</key> <string>3</string> <key>recipeImage</key> <string>asdd.jpg</string> <key>time</key> <string>15</string> <key>recipeName</key> <string>Puding</string> <key>recipeDetail</key>

the count is 8 for this reason. It consider each key as an array element.

This is C not C++ (eventhough C++ brings enough C compatibility to make that code valid using a conforming C++ compiler with #include <stdio.h>).
The specifier %c is for characters. You're reading and writing int.

Thus, you should use %i.

int a; int b; printf("a"); scanf("%i", &a); printf("b"); scanf("%i", &b); a=a+b; printf("%i", a);

Output

a5 b7 12

Because you are using strings rather than parameters, your example is vulnerable to SQL injection. It's best to avoid pg_ functions. In your case there are two things you need to take into account:

Learn the Drupal API (considering you are using Drupal this would be the best for code consistency

Use stored procedures
Use a library like PDO or pg_query_params which takes care of parameterized queries

Normally you use stored procedures in addition to PDO, unfortunately sometimes this is not manageable because you have too much code. My advice is to use as much stored procedures as possible.

15043393 0 Unexplained heroku timeouts

I have a rails 3.2.11 app deployed on Heroku that has been fairly stable over time. In the last 24 hours, pingdom has been reporting Timeouts which I can't find any "H1X" related errors in the logs at the same time.

I am occassionally able to reproduce the timeouts in google chrome. where I would get this message after about 30 seconds of requesting any page:

Chrome browser error No data received Unable to load the webpage because the server sent no data. Here are some suggestions: Reload this webpage later. Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

The app will then begin serving requests normally until it happens again.

I know this is not enough info, but I can't find anything useful yet in newrelic or scanning the logs that correlates to when the error occured.

In one instance, i was reproducing the error in the browser while viewing the heroku logs and when the timeout occurred, there was no evidence of the request showing up in the logs. Its like the failed requests never make it into the app.

I have a service that renders a report from SSRS which works perfectly fine with one page, however when I tried to change the code to render multiple pages separately I can't seem to get it to work as expected.

I used a guide on the MSDN blogs (http://blogs.msdn.com/b/bryanke/archive/2004/02/11/71491.aspx#code) to try and achieve this, but my StreamIDs doesn't seem to be working as I expected.

Here's my code from the Render() method onwards (the rest seems to be okay, but I can provide on request):

 var firstPage = rsExec.Render(format.ToString(), deviceInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs); var numberOfPages = streamIDs.Length + 1; results = new Byte[numberOfPages][]; results[0] = firstPage; if (numberOfPages > 1) { for (int i = 1; i < numberOfPages; i++) { deviceInfo = $@" <DeviceInfo> <OutputFormat>JPEG</OutputFormat> <StartPage>{i + 1}</StartPage> </DeviceInfo>"; results[i] = rsExec.Render(format.ToString(), deviceInfo, out extension, out encoding, out mimeType, out warnings, out streamIDs); } }

you could also add it directly in your page-template (this is called 'inline styling'):

a couple of lines below your opening body tag you'll find

<div> <a href="http://forum.banaisbul.com"><img src="http://forum.banaisbul.com/wp-content/uploads/2014/09/banaisbulsiyah.jpg" border="0" alt="Link to this page"></a> </div>

and you need to change it to

<div style="background-color:#404040"> <a href="http://forum.banaisbul.com"><img src="http://forum.banaisbul.com/wp-content/uploads/2014/09/banaisbulsiyah.jpg" border="0" alt="Link to this page"></a> </div>

<Edit> Although one object can access private properties of all objects of the same class, you cannot access protected methods of an object from other class even if the protected method is defined in a common super class.

So while this code compiles:

public class Test { private int x; private void change(Test test) { test.x = test.x + 1; } public static void main() { Test test1 = new Test(); Test test2 = new Test(); test1.change(test2); } }

The following code will not compile:

public class Test2 { public static void main() { Test1 test1 = new Test1(); test1.clone(); // The method clone() from the type Object is not visible } }

</Edit>

Being able to call toString(), equals(Object), hashCode() and getClass() on all objects makes things a lot easier.

 clone() and finalize() are protected. So in order to be able to call them from the outside the subclass has to increase the visibility. And that is obviously a design decision.

To be honest, i have no idea why Sun decided that all object are "locks" and have notify(), notifyAll(), wait(long), wait(long, int). From my point of view those method should not be in Object at all but in a specialized Lock-class. But I guess there was a good reason to have them there in the very early days and it cannot be changed nowadays without breaking compatibility.

Hide the Prelude's (!!) operator and you can define your own (!!) operator:

You can even make a type class for your new (!!) operator if you prefer.

If you can modify the configuration file on the server here's what you can do to get the exception information through the service.

You need to add a service behavior section to the server's config.

<behaviors> <serviceBehaviors> <behavior name="serviceNameBehavior"> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> </behaviors>

Then associate the service with that behavior.

<service name="serviceName" behaviorConfiguration="serviceNameBehavior" ...

The problem is that you are loading the lang file from inside a function, which means that $lang does not get placed into the global scope but rather the local function scope.

Minimum required change to make it work (but not a good idea)

Assuming you want $lang to be placed inside the global scope, you could do so explicitly:

public function lang($file, $language){ require 'languages/'.$language.'/'. $file . '.php'; $GLOBALS['lang'] = $lang; // "export" to global scope }

A much better idea

There are several things that can be improved:

The function above writes the contents of the global variable $lang "behind the caller's back" -- that's not good design, and it makes the code harder to maintain
As it stands, it loads the language file from scratch every time you call it

You can kill both birds with one stone by storing the language file contents inside a static local variable and returning it from the function: there is no more writing to the global scope, and the variable keeps its contents so you don't have to reload the language file every time. It would look like this:

public function lang($file, $language){ static $cache = array(); if (empty($cache[$language][$file])) { // load language files on demand require 'languages/'.$language.'/'. $file . '.php'; $cache[$language][$file] = $lang; } return $lang; // return requested data, which is now definitely cached }

And to use it, you would do:

$lang = $this->lang('global', 'en');

Dumping raw variables into the global scope like this is not always the best idea, but depending on the circumstances (small projects) it might be OK.

There is never a guarantee that you will not get stuck in a local optimum, sadly. Unless you can prove certain properties about the function you are trying to optimize, local optima exist and hill-climbing methods will fall prey to them. (And typically, if you can prove the things you need to prove, you can also select a better tool than a neural network.)

One classic technique is to gradually reduce the learning rate, then increase it and slowly draw it down, again, several times. Raising the learning rate reduces the stability of the algorithm, but gives the algorithm the ability to jump out of a local optimum. This is closely related to simulated annealing.

I am surprised that Google has not helped you, here, as this is a topic with many published papers: Try terms like, "local minima" and "local minima problem" in conjunction with neural networks and backpropagation. You should see many references to improved backprop methods.

18634136 1 Why do I get IndexError: list index out of range?

Now, the output is:

0 cross tick Traceback (most recent call last): File "C:\Users\Michele2\Desktop\Arcrate\MyCASH\Python Code\Scraping\Scraping1.3(clean)TEST.py", line 246, in <module> "; " + MAIN_list[10][x]) IndexError: list index out of range

I know that you'd usually get this error for variables outside the actual length of the list, but here I get the right output when I call it singularly (ie. row 3 of the output) but not when I try to print the list as a whole. Any though would be welcome.

Thanks

First, to specify E explictly, you could use the more verbose lambda syntax. This would look like this:

myObservable.handleError { it : IOException -> it.printStackTrace() }

Alternativly, you could add an additional parameter to help the compiler infer the type. This could look something like this:

public inline fun <reified E : Throwable, R> Observable<R>.handleError( typeHint: (E) -> Unit, crossinline handler: (E) -> Unit ) = onErrorResumeNext f@{ return@f when (e) { is E -> { handler(e); Observable.empty() } else -> Observable.error(e) } } fun <T> of() : (T) -> Unit = {}

Usage:

myObservable.handleError(of<IOException>()) { it.printStackTrace() }

36841914 0 How do I get the column count of a table when there are cells with rowspan/colspan?

How do I get the column count of a table when there are cells with rowspan/colspan?

UPDATE: In this question I mean the classical (as far as I know) use of tables, when it's necessary to use the colspan, though it's not required by the specification (and table will look ugly but it will be valid).

I need JavaScript/jQuery to get 11 for the following table (as 11 is the maximum number of columns for this table):

<table border="1"> <thead> <tr> <th rowspan="3">Lorem</th> <th rowspan="3">ipsum</th> <th rowspan="3">dolor</th> <th colspan="4">sit</th> <th colspan="4">amet</th> </tr> <tr> <th colspan="3">consectetur</th> <th rowspan="2">adipisicing</th> <th rowspan="2">elit</th> <th rowspan="2">sed</th> <th rowspan="2">do</th> <th rowspan="2">eiusmod</th> </tr> <tr> <th>tempor</th> <th>incididunt</th> <th>ut</th> </tr> </thead> <tbody></tbody> </table>

https://jsfiddle.net/toahb3a3/

My personal solution is:

$(function(){ var max = 0; $('tr').each(function(){ var current = 0; $(this).find('th').each(function(){ var colspan = $(this).attr('colspan'); current += Number(colspan ? colspan : 1); }); max = Math.max(current, max); }); console.log(max); });

https://jsfiddle.net/mt7qhbqd/

UPDATE: To solve this problem we need the sum of th elements plus their colspan in the very first row of thead. Thanks to Andy for his code, it's really compact and it gave me the thought that I need only the first row. Also, thanks to Quentin who pointed me to the case when colspan is not necessarily used, so Andy's alogrithm won't work (but Quentin's will). Also thanks to Quentin for helping me with the title, as my English isn't good enough.

Using the list monad would let you structure the computation like a tree, but it would lose the source information. At the end, you would have a list of results, but you would not know where each individual result came from.

If this is all you care about, the list monad is perfect. Let's imagine you have a non-deterministic step function:

step :: State -> [State]

if we want to just step it through a bunch of times, we could write something like:

startState >>= step >>= step >>= step

this will give us all the possible results after 3 steps. If we wanted to generalize this to any number, we could write a simple helper function by using the monadic composition operator (<=<) from Control.Monad. This works just like ., except for function of the form a -> m b instead of normal functions (a -> b). It could look something like this:

stepN :: Int -> (State -> [State]) -> State -> [State] stepN n f = foldr (<=<) return (replicate n f)

Now to get three non-deterministic steps, we can just write stepN 3 step. (You'll probably want to come up with better names for the functions :P.)

In summary: using the list monad, the computation itself is shaped like a tree, but you only get to look at the results at the end. This should be clear from the types involved: at the end, you get a [State], which is by its very nature flat. However, the function State -> [State] branches, so the computation to arrive to the end has to look like a tree.

For things like that, the list type is very convenient to use.

22771957 1 python subprocess sends backslash before a quote

I have a string, which is a framed command that should be executed by in command line

cmdToExecute = "TRAPTOOL -a STRING "ABC" -o STRING 'XYZ'"

I am considering the string to have the entire command that should be triggered from command prompt. If you take a closer look at the string cmdToExecute, you can see the option o with value XYZ enclosed in SINGLE QUOTE. There is a reason that this needs to be given in single quote orelse my tool TRAPTOOL will not be able to process the command.

I am using subprocess.Popen to execute the entire command. Before executing my command in a shell, I am printing the content

print "Cmd to be exectued: %r" % cmdToExecute myProcess = subprocess.Popen(cmdToExecute, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=False) (stdOut, stdErr) = myProcess.communicate()

The output of the above command is, Cmd to be executed: TRAPTOOL -a STRING "ABC" -o \'XYZ\'.

You can see that the output shows a BACKWARD SLASH added automatically while printing. Actually, the \ is not there in the string, which I tested using a regex. But, when the script is run on my box, the TRAPTOOL truncates the part of the string XYZ on the receiving server. I manually copy pasted the print output and tried sending it, I saw the same error on the receiving server. However, when I removed the backward slash, it sent the trap without any truncation.

Can anyone say why this happens?
Is there anyway where we can see what command is actually executed in subprocess.Popen?
Is there any other way I can execute my command other that subprocess.Popen that might solve this problem?

I am trying to fix an bug found in a mature program for Fujitsu MB90F543. The program works for nearly 10 years so far, but it was discovered, that under some special circumstances it fails to do two things at it's very beginning. One of them is crucial.

After low and high level initialization (ports, pins, peripherials, IRQ handlers) configuration data is read over SPI from EEPROM and status LEDs are turned on for a moment (to turn them a data is send over SPI to a LED driver). When those special circumstances occur first and only first function invoking just a few EEPROM reads fails and additionally a few of the LEDs that should, don't turn on.

The program is written in C and compiled using Softune v30L32. Surprisingly it is sufficient to add single __asm(" NOP ") in low level hardware init to make the program work as expected under mentioned circumstances. It is sufficient to turn off 'Control optimization of pointer aliasing' in Optimization settings. Adding just a few lines of code in various places helps too.

I have compared (DIFFed) ASM listings of compiled program for a version with and without __asm(" NOP ") and with both aforementioned optimizer settings and they all look just fine.

The only warning Softune compiler has been printing for years during compilation is as follows:

*** W1372L: The section is placed outside the RAM area or the I/O area (IOXTND)

I do realize it's rather general question, but maybe someone who has a bigger picture will be able to point out possible cause.

Have you got an idea what may cause such a weird behaviour? How to locate the bug and fix it?

During the initialization a few long (about 20ms) delay loops are used. They don't help although they were increased from about 2ms, yet single NOP in any line of the hardware initialization function and even before or after the function helps.

Both the wait loops works. I have checked it using an oscilloscope. (I have added LED turn on before and off after).

I have checked timming hypothesis by slowing down SPI clock from 1MHz to 500kHz. It does not change anything. Slowing down to 250kHz makes watchdog resets, as some parts of the code execute too long (>25ms).

One more thing. I have observed that adding local variables in any source file sometimes makes the problem disappear or reappear. The same concerns initializing uninitialized local variables. Adding a few extra lines of a code in any of the files helps or reveals the problem.

void main(void) { watchdog_init(); // waiting for power supply to stabilize wait; // about 45ms hardware_init(); clear_watchdog(); application_init(); clear_watchdog(); wait; // about 20ms test_LED(); {...} } void hardware_init (void) { __asm("NOP"); // how it comes it helps? - it may be in any line of the function io_init(); // ports initialization clk_init(); timer_init(); adc_init(); spi_init(); LED_init(); spi_start(); key_driver_init(); can_init(); irq_init(); // set IRQ priorities and global IRQ enable }

1108442 0 Problem with ModelAndView and ModelMap in AnnotationController, Springframework

I have a question that is a point difference between ModelAndView and ModelMap.

I want to maintain modelAndView when requestMethod is "GET" and requestMethod is "POST". My modelAndView saved others.

So I made modelAndView return type to "GET", "POST" methods.

But, Request lost commandObject, form:errors..., if request return showForm on "POST" because request validation failed.

example)

private ModelAndView modelAndView; public ControllerTest{ this.modelAndView = new ModelAndView(); } @RequestMapping(method = RequestMethod.GET) public ModelAndView showForm(ModelMap model) { EntityObject entityObject = new EntityObject(); CommandObject commandObject = new CommandObject(); commandObject.setEntityObject(entityObject); model.addAttribute("commandObject", commandObject); this.modelAndView.addObject("id", "GET"); this.modelAndView.setViewName("registerForm"); return this.modelAndView; } @RequestMapping(method = RequestMethod.POST) public ModelAndView submit(@ModelAttribute("commandObject") CommandObject commandObject, BindingResult result, SessionStatus status) { this.commandValidator.validate(commandObject, result); if (result.hasErrors()) { this.modelAndView.addObject("id", "POST"); this.modelAndView.setViewName("registerForm"); return this.modelAndView; } else { this.modelAndView.addObject("id", "after POST"); this.modelAndView.setViewName("success"); } status.setComplete(); return this.modelAndView; }

If you follow this tutorial it should work:

http://sfmlcoder.wordpress.com/2011/08/16/building-sfml-2-0-with-make-for-gcc/

then put the sfml 2 folder with all the dependencies inside of your /usr/include/ folder and compile with g++ main.o -o main -lsfml-graphics -lsfml-window -lsfml-system and run with with ./main it should work perfectly. I actually setup a key mapping in vim that compiles using that command and then runs it and its works flawlessly for me.

Linq was build with an functional style in mind. Using it the imperative way would not end up in elegant code. So don't transform after the query but in the query - put the logic in the projection section (select). (Much like Anthony's answer)

var str = (from i in Regex.Split("TheQuickBrownFox", "") select Regex.IsMatch(i, "[A-Z]") ? " " + i : i) .Aggregate((str1, str2) => str1 + str2); Console.WriteLine(str);

The exact value of the float is 1.100000000000000088817841970012523233890533447265625. Python isn't somehow keeping track of the original string. When Python stringifies it with str, it truncates to 12 digits.

>>> x = 1.0/9 >>> print decimal.Decimal(x) # prints exact value 0.111111111111111104943205418749130330979824066162109375 >>> print x # truncated 0.111111111111

Even with repr, Python uses the shortest string that will round to the original float when parsed with float.

>>> print repr(x) 0.1111111111111111

If you want to parse JSON and get Decimal instances instead of float, you can pass a parse_float argument to the load(s) function:

>>> json.loads('{"foo": 1.234567890123456789}', parse_float=decimal.Decimal) {u'foo': Decimal('1.234567890123456789')}

The above call causes decimal.Decimal to be called to parse numbers in the JSON string, bypassing the rounding that would occur with intermediate float or str calls. You'll get exactly the number specified in the JSON.

Note that the API distinguishes between the functions used to parse things that look like floats, things that look like ints, and things that look like Infinity, -Infinity, or NaN. This can be a bit inconvenient if you want all 3 categories to be handled the same way:

>>> json.loads('{"foo": 1.234567890123456789}', ... parse_float=decimal.Decimal, ... parse_int=decimal.Decimal, ... parse_constant=decimal.Decimal) {u'foo': Decimal('1.234567890123456789')}

I would define a question class that has a list of answers and return that.

public class Answer { public string AnswerText {get; set;} } public class Question { public List<Answer> Answers {get; set; } }

In your class that calls getQuestion, you should return the question object you're looking for that contains its answers.

public class MainClass { public List<Question> Questions {get; set;} public Question GetQuestion(/* some criteria, like question number or something */) { var selectedQuestion = // get the question from Questions based on some criteria return selectedQuestion; } }

And then do whatever you need to do in the presentation layer for the end-user to show them the question and answers.

What you'll typically do in such a scenario is first create an interface, like ITableStorage and then create an implementation (AzureTableStorage for example) that wraps around the Azure specific stuff.

This makes it easy to replace the actual implementation with a mock/stub during your unit tests. You can take a look at the Windows Azure Helpers for an example of such an interface and a wrapper implementation: Windows Azure Helpers.

This is a good blog post about unit testing and Windows Azure: http://blogs.southworks.net/fboerr/2010/07/23/windows-azure-storage-tdd-and-mocks/

And to answer your question, yes you can use this with MSTest.

Like @CL was saying you can't have 2 records with the same PRIMARY KEY

this Table should be built with 3 columns.

A_ID PRIMARY KEY AUTO INCREMENT NOT NULL
time DATETIME (probably NOT NULL as well
data REAL

in other words, Never set the Primary key in your code, let the database auto increment it for you, or use a GUID.

this line

data=(1,2)

is the only thing that is being inserted into your database. so the only record in the database will be the one you insert, which is 1,2

1464664 0 Changing the colour of Aero glass for my window?

I'm using DwmExtendFrameIntoClientArea in my WPF application to get the glass effect. This is working fine. What I'd like to do is change the colour used for the glass -- I'm writing a countdown timer, and I'd like the window to be the normal glass colour most of the time, and then to go red (but still with glass) when the time runs out.

I found this question, which talks about how to apply a gradient glass, and that works fine when picking a different colour. Unfortunately, the borders are not coloured appropriately.

When I turn off the borders by using ResizeMode="NoResize", then I end up with square corners. I'd like to keep the rounded corners.

I looked at creating an irregularly-shaped window, by using AllowTransparency="True" and that works fine, but doesn't look like an Aero glass window. It looks a bit flat.

So: my question: how do I create a window in WPF that looks like Aero glass transparency, but uses a different colour?

If you want to do it with DSC, here's a sample: https://github.com/bmoore-msft/AzureRM-Samples/tree/master/VMDSCInstallFile. Ed's answer might be a simpler approach though. The key here is getting the credentials to the VM to be able to pull from storage. That means whether you're using DSC or a custom script, you need to get the location/uri and a sasToken to the script (unless the files are unsecured). The DSC sample above will give you a way to pass the uri/token that will work in either workflow. Look at the PS script in the root to see how the uri & token are created and passed to the template deployment.

I have this code in doInBackground method of an AsyncTask:

Every object has an internal property, [[Prototype]], linking it to another object:

object [[Prototype]] -> anotherObject

Some environments expose that property as __proto__:

anObject.__proto__ === anotherObject

You create the [[Prototype]] link when creating an object:

var object = Object.create( anotherObject ) // imagine: // object.__proto__ = anotherObject

In traditional javascript, the linked object is the prototype property of a function:

object [[Prototype]] -> aFunction.prototype

and you create the [[Prototype]] link with new (but this isn't obvious):

var object = new aFunction; // imagine: // object.__proto__ = aFunction.prototype;

Remember:

Every object has a link, [[Prototype]], sometimes exposed as __proto__.
Every function has a prototype property. It may be a source of values shared with other objects, or it may go unused.

Here is a stab at a solution. It needs a bit of cleanup but should give you everything you need.

Create a custom ActionFilter, and then decorate your methods with it.

[ManagerIdAuthentication] public ActionResult Details(int id) { // Gets executed if the filter allows it to go through. }

The next class can be created in a separate library so you can include it in all your actions that require this validation.

public class ManagerIdAuthentication : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { // the next line needs improvement, only works on an httpGet since retrieves // the id from the url. Improve this line to obtain the id regardless of // the method (GET, POST, etc.) var id = filterContext.HttpContext.Request.QueryString["id"]; var employee = employeeRepository.Get(id); var user = filterContext.HttpContext.User.Identity; if (employee.managerId == user.managerId) { var res = filterContext.HttpContext.Response; res.StatusCode = 402; res.End(); filterContext.Result = new EmptyResult(); //may use content result if want to provide additional info in the error message. } else { // OK, let it through. } } }

Even if you look up the method in both cases (i.e. before 2nd and 3rd loop), the first lookup takes way less time than the second lookup, which should have been the other way around and less than a regular method call on my machine.

Neverthless, if you use the 2nd loop with method lookup, and System.out.println statement, I get this:

regular call : 740 ms look up(2nd loop) : 640 ms look up ( 3rd loop) : 800 ms

Without System.out.println statement, I get:

regular call : 78 ms look up (2nd) : 37 ms look up (3rd ) : 112 ms

Turns out only the captures, not the args get passed down the chain.

According to the doc:

$c->visit( $action [, \@captures, \@arguments ] )

So I was able to have success by doing the following:

$c->visit('/assets/widget',[$arg],[$arg])

The first array of args hits the first action and stops, but the second array travels all the way down the chain like I wanted.

I expected $c->visit('/assets/widget',[],[$arg]) to work, but it does not.

However, after all that I realized I can't just grab the body response that way, which was the ultimate goal. Either way, hopefully my goose chase was helpful to someone.

This seems to be a problem on Ubuntu (perhaps other Debian-based distros) with the Java CACerts keystore. For some reason this does not always include the full list of entries.

To solve this, try the following:

Delete the cacerts file

sudo rm /etc/ssl/certs/java/cacerts
Re-build the cacerts file using the dpkg postinstall script:

sudo /var/lib/dpkg/info/ca-certificates-java.postinst configure

This should re-generate the cacerts file and the problem should be resolved.

If you have some form of session identifier you can increment a count of times that request has been made. This isn't bullet proof however, clearing out session cookies will allow that request to be made again.

You will need some form of login to prevent someone clearing their cookies, or even a cURL script looping.

Edit:

As a stop-gap measure, you could add a form of CSRF protection, a one-time-use hash would need to be applied to each request to make it valid.

One way would be to put project B in a new repository, but this would lose the history of previous code. Is there a way to retain the history?

Though I would have preferred a single code base, it is too difficult to add conditional statements to separate these.

Is it good I a idea to use command line instead of GUI?

Yes.

And is it normal to compare every file I modified to the old ones with WinMerge after every time I modified them?

Yes.

You must use the Double.IsInfinity() and Double.IsNaN() methods.

if (Double.IsInfinity(SampleInterval)) { //TODO } if (Double.IsNaN(SampleInterval)) { //TODO }

Don't compare directly to Double.NaN, it will always return false.

20838609 0 Want to know the raw sql query when user other than superuser logs in the system

I have an application which involves large number of users. among those, some are staff members.

My problem

When a user from a certain group let say A logs in, it takes 5 minute to see the admin screen (index page). I want to fix this problem.So the question is , What is the sql query when a user from a certain group logs in the admin of the project.

I know how to see query

str(MyModel.objects.filter(name="my name").query)

but again not getting how to generate the query for that case

17313558 1 Form for multiple models

Suppose I have two models:

class Topic(models.Model): title = models.CharField() # other stuff class Post(models.Model): topic = models.ForeignKey(Topic) body = models.TextField() # other stuff

And I want to create a form contains two fields: Topic.title and Post.body. Of course, I can create the following form:

class TopicForm(Form): title = forms.CharField() body = forms.TextField() # and so on

But I don't want to duplicate code, since I already have title and body in models. I'm looking for something like this:

class TopicForm(MagicForm): class Meta: models = (Topic, Post) fields = { Topic: ('title', ), Post: ('body', ) } # and so on

Also, I want to use it in class based views. I mean, I would like to write view as:

class TopicCreate(CreateView): form_class = TopicForm # ... def form_valid(self, form): # some things before creating objects

As suggested in comments, I could use two forms. But I don't see any simple way to use two forms in my TopicCreate view - I should reimplement all methods belongs to getting form(at least).

So, my question is:

Is there something already implemented in Django for my requirements? Or is there a better(simpler) way?

Do you know a simple way with using two forms in class based view? If so, tell me, it could solve my issue too.

There is mistake in the Parcelable implementation.

First of all parcelable implementation states that: the fields passed in News(Parcel in) Constructor should be written in the same sequence in writeToParcel() method. Thats called Marshalling and Unmarshalling.

Corrections:

Drawable cannot be passed a parameter in Parcelable.
News Parcelable implementation.

Missed some of the fields its just for your understanding.

public class News implements Parcelable { public static final String TAG = "model_news"; private JSONObject object; private int id; private String type; private String title; private Boolean comment_disabled; private String category_name; private String url; private Image images; private Date date; private Boolean is_video; protected News(Parcel in) { id = in.readInt(); type = in.readString(); title = in.readString(); category_name = in.readString(); url = in.readString(); } public static final Creator<News> CREATOR = new Creator<News>() { @Override public News createFromParcel(Parcel in) { return new News(in); } @Override public News[] newArray(int size) { return new News[size]; } }; @Override public int describeContents() { return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest.writeInt(id); dest.writeString(type); dest.writeString(title); dest.writeString(category_name); dest.writeString(url); } } public class Image implements Parcelable { public static final String TAG = "model_image"; private JSONObject imageObj; private JSONObject original; private String source; private int width; private Drawable image; protected Image(Parcel in) { source = in.readString(); width = in.readInt(); } public static final Creator<Image> CREATOR = new Creator<Image>() { @Override public Image createFromParcel(Parcel in) { return new Image(in); } @Override public Image[] newArray(int size) { return new Image[size]; } }; @Override public int describeContents() { return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest.writeString(source); dest.writeInt(width); } }

All the qt widget classes can be styled via stylesheets, depending where create your popup (designer, or in code) assign it a stylesheet with the look that you want it to have. You can test stylesheets in designer by assigning a style to a widget using the context menu of the widget

After further review, the QSystemTrayIcon::showMessage() call puts up a system notification. Which I don't know if it can be styled. The qsystemtrayicon_win.cpp file in the qt distribution shows a workaround and shows a way of how to find the location of the icon in the tray (see QSystemTrayIconSys::findIconGeometry). Once you have the location you could pop up your own window at that location. I did not look to deep, I don't know if you can get to the location for the icon with the information that you have on the public side of Qt. You might have to go all windows with that.

You'd have to cast to decimal for smaller numbers

 select cast(power(cast(101 as float),50) as decimal(38,0)) % 221

 select power(cast(101 as decimal(38,0)),50) % 221

This fails though with such a large number

But then it makes no sense anyway for larger numbers.

float is accurate to 15 signficant figures.
101 ^ 50 = 1.64463182184388E+100
the margin of error (float approximation) is about 82 orders of magnitude (1E+82) higher than your modulo 221

Any answer from the modulo is utter rubbish

Edit:

Decimal goes to around 10^38

Take a float number at 10^39, or 1E+39, then you are accurate to around 1E24 (15 signficant figures).

Your modulo is 221 = 2.2E+2

You margin of error ie 1E+24/2.2E+2 = 4.4E+21

Just to be 100% clear, your accuracy is 4,400,000,000,000,000,000,000,000 times greater than your modulo.

It isn't even approximate: it's rubbish

For future reference,

You should be using a WebService (ASMX) file to process and return your JSON. Remember that the javascript success block will only be called with a returned http 200 status code.

If you ever get to using the MVC framework its even easier by just returning a JSON result type.

If you wanted to keep the aspx hack, you can call the following to remove the HTML

response.clear(); response.write(yourJSON); response.end();

But again i would discourage from doing this and recommend the dedicated service.

39642325 0 Sox cannot determine type of file

I'm using node js and express with sox node bindings. I have a temporary uploaded file that I need to identify, but since the file does not have an extension, SoX gives me this error:

sox.identify(file, function(err, info) { if (err) { console.log(err) throw(err) } });

sox FAIL formats: can't determine type of file C:\Users\User\Documents\Project\Media\temp\riqDeq15151sf14FWa

I'm using multer for saving the uploaded file temporarily. Is there anyway to have SoX identify the file even though it doesn't have an extension?

Correct...and to launch you even further, check out this modification.

http://jsfiddle.net/Fv27b/2/

Here, you'll see that not only are we combining the options, but we're creating our own binding entirely...which results in a much more portable extension of not just this view model, but any view model you may have in your project...so you'll only need to write this one once!

ko.bindingHandlers.colorAndTrans = { update: function(element, valAccessor) { var valdata = valAccessor(); var cssString = valdata.color(); if (valdata.transValue() < 10) cssString += " translucent"; element.className = cssString; } }

To invoke this, you just use it as a new data-bind property and can include as many (or as few) options as possible. Under this specific condition, I might have just provided $data, however if you're wanting a reusable option you need to be more specific as to what data types you need as parameters and not all view models may have the same properties.

data-bind="colorAndTrans: { color: color, transValue: number }"

Hope this does more than answer your question!

In Excel, you can do it using an array formula to search for the next frequency which is in range:-

=MATCH(1,(B2:B$10>=49)*(B2:B$10<=51),0)-1

if your frequencies start in B2.

Must be entered in C2 with CtrlShiftEnter

Here is a modified version which allows for the case where the last frequency is out of range, assuming there are no blanks between frequency values and one or more blanks at the end:-

=MATCH(1,(B2:B$10>=49)*(B2:B$10<=51)+(B2:B$10=""),0)-1

Options 1, 2, and 5 seems OK. I don't see how the 3rd option could work because the browser does not need to store changes in field values.

So unless you go the single-page-web-application way, like AngularJS, and avoid your navigation problem by not navigating to another page, you need to deal with the browse cache problem. The user could also have clicked a bookmark which is different but similar to the back button problem.

Additionally, not a very strong argument, but if you look at Stack Overflow you can see it uses Cache-Control and ajax requests.

UserDefaults - Gives you a new object, each object is allocated a different memory and deallocated when object scope is finished.

UserDefaults.standard - Gives you the singleton object by using the class method standard the object received by this method is allocated single memory throughout the application.

And the usage of them if you´re interesedted in that:

// Set UserDefaults.standard.set("YOUR STRING", forKey: "key") UserDefaults().set("YOUR STRING", forKey: "key") // Get UserDefaults.standard.string(forKey: "key") UserDefaults().string(forKey: "key")

If you want to specify a literal color value in a geom_segment, you should not include it in the aes(). For example using this test data

DF_for_plotting <- data.frame( variable=rep("StrpCnCor",4), value=c(0, 50.79330935, 81.127731, 100) )

you can do

ggplot() + geom_segment(data=DF_for_plotting, aes(x=value[1], xend=value[2]-0.001, y=1, yend=1), colour="green", size=10) + geom_segment(data=DF_for_plotting, aes(x=value[2], xend=value[3]-0.001, y=1, yend=1), colour="blue", size=10) + geom_segment(data=DF_for_plotting, aes(x=value[3], xend=value[4]-0.001, y=1, yend=1), colour="red", size=10)

enter image description here

or with hex colors

ggplot() + geom_segment(data=DF_for_plotting, aes(x=value[1], xend=value[2]-0.001, y=1, yend=1), colour="#9999CC", size=10) + geom_segment(data=DF_for_plotting, aes(x=value[2], xend=value[3]-0.001, y=1, yend=1), colour="#66CC99", size=10) + geom_segment(data=DF_for_plotting, aes(x=value[3], xend=value[4]-0.001, y=1, yend=1), colour="#CC6666", size=10)

enter image description here

Although because you're not mapping anything to the color aesthetic, no legend will be provided.

When you put it in the aes(), you're not specifying a literal value, you are just specifying a literal value to associate with a color it doesn't matter if you use aes(color="red") or aes(color="determination"); it just treats it as a literal character value and will use it's own color palate to assign a color to that character value. You can specify your own colors with scale_fill_manual For example

ggplot() + geom_segment(data=DF_for_plotting, aes(x=value[1], xend=value[2]-0.001, y=1, yend=1, colour="a"), , size=10) + geom_segment(data=DF_for_plotting, aes(x=value[2], xend=value[3]-0.001, y=1, yend=1, colour="b"), , size=10) + geom_segment(data=DF_for_plotting, aes(x=value[3], xend=value[4]-0.001, y=1, yend=1, colour="c"), size=10) + scale_color_manual(values=c(a="green",b="blue",c="red"))

enter image description here

ggplot() + geom_segment(data=DF_for_plotting, aes(x=value[1], xend=value[2]-0.001, y=1, yend=1, colour="a"), , size=10) + geom_segment(data=DF_for_plotting, aes(x=value[2], xend=value[3]-0.001, y=1, yend=1, colour="b"), , size=10) + geom_segment(data=DF_for_plotting, aes(x=value[3], xend=value[4]-0.001, y=1, yend=1, colour="c"), size=10) + scale_color_manual(values=c(a="#9999CC",b="#66CC99",c="#CC6666"))

enter image description here

Here i called the three groups "a", "b", and "c" but you could also call then "green","blue","red" if you want -- it just seems odd to have a legend that tells you what color is green.

How do I read json with bash?

You can use jq for that. First thing you have to do is extract the list of hostnames and save it to a bash array. Running a loop on that array you would then run again a query for each hostname to extract each element based on them and save the data through redirection with the filename based on them as well.

So apparently, you can't just take any temporary key and sign the APPX with it. In particular the certificate subject lines must match(the "publisher name"). I do not know of a better way of determining what the subject line much actually be so bare with me. First, try to use signtool and sign the APPX file with any temporary key. Now go to Event Viewer. Then to Applications and Services and then Microsoft and then Windows and then AppxPackaging and finally Microsoft-Windows-AppxPackages/Operational. There should be an error event that just happened from that build. Check it. It should say something like

Error 0x800700B: The app manifest publisher name (CN=random-hex-number) must match the subject name of the signing certificate (CN=MyWrongName)

So, now make sure to hang on to that random-hex-number. That needs to be the subject line of the certificate and is the cause of the error. To generate a working certificate:

makecert.exe mycert.cer -r -n "CN=random-hex-number" -$ individual -sv private.pkv -pe -cy end pvk2pfx -pvk private.pkv -spc mycert.cer -pfx mytemporarykey.pfx

Now finally, you should have a temporary key that will work with signtool!

Hopefully this answers serves other people well.

Arrays are only meant to store numeric indices, you can create members like Nom but these will in no way react like a normal numeric index.*

Either use an object, or push objects into your array.

var personnes=[]; personnes.push({ "Nom" : "Julie", "Age" : 100 }); personnes[0].Nom // -> Julie

var personnes={}; personnes["Julie"] = 100; // equal to: personnes.Julie = 100;

var personnes={}; personnes["Julie"] = {"age":100 /*,"more attributes":"here"*/}

However, the last two notations assume that the names are unique!

*You can do the following:

var ar = []; ar.attr = 5; ar.attr; // -> 5 ar.length; // -> 0, since attr is not enumerable // also all other regular array operation won't affect attr

Did you use DialogFragments ? The missing part will be the setStyle call then. You have to do this before the Fragment gets shown.

@NonNull public static SlowConnectionDialogFragment newInstance(final String errorText) { final Bundle bundle = BundleArgs.create(errorText); final SlowConnectionDialogFragment instance = new SlowConnectionDialogFragment(); instance.setStyle(STYLE_NO_TITLE, android.R.style.Theme_DeviceDefault_Light_Dialog); instance.setArguments(bundle); return instance; }

For Dialogs are some kind of other Styling properties needed, to get the floating window back. So you should consider creating another theme for Dialogs.

Do you see this behavior when you start Emacs without your init file (emacs -Q)? I doubt it. If not, then recursively bisect your init file to find out what is causing the problem.

The minibuffer uses its own keymaps, which are local and which therefore take precedence over global keymap bindings.

However, any minor-mode keymaps take precedence over local keymaps. So if, for example, you have a (global) minor mode turned on that binds <tab> then that will override any binding for that key in the minibuffer keymaps.

Another thing you can do is simply bind whatever command you want to <tab> in the minibuffer keymaps. But again, you should not need to do that, if you want the usual <tab> behavior for the minibuffer.

[Another possible confusion: Some things, such as Isearch, which you might think use the minibuffer do not use it. Isearch uses its own keymap, isearch-mode-map.]

UPDATE after your comment:

Assigning a key in the global map, as you have done, should not affect what that key does in the minibuffer, provided it has a different binding in the minibuffer keymaps. TAB is typically bound in all of the minibuffer completion keymaps (but not in the non-completion minibuffer keymaps).

See the Elisp manual, nodes Completion Commands and Text from Minibuffer for information about the minibuffer keymaps.

To see what the current bindings are for a keymap that is associated with a variable (such as minibuffer-local-completion-map), load library help-fns+.el and use C-h M-k followed by the keymap variable's name. (See Help+ for more information about the library.)

If you do not want TAB to use your global command binding in the non-completion minibuffer maps (minibuffer-local-map, minibuffer-local-ns-map), then just bind it in those maps to whatever command you like. But for the completion maps you should not need to do anything - TAB should already be bound there.

Did you try emacs -Q, to see if something in your init file is interfering? If not, do that first.

13954594 0 building website using webservice and SOAP in ASP.NET

I am new in web application. I don't know much about web services and SOAP. I am studying. Trying to understand what they are?

in parallel i wanted to make a simple demonstration using web service and SOAP protocol. I have a form(default.aspx) in my localhost. Here is the picture:

enter image description here

on clicking submit button, data will be passed to another page say, "welcome.aspx". I think this process can be done through a web service and following SOAP protocol.

I know, this can be done using nothing and following nothing, but to get a simple concept, i want the simplest practical example to be done.

any direction will be great, no code may be needed. Just let me know, at this point, how should i use web services and SOAP.

This is a job for merge:

KEYS <- data.frame(A = AList, B = BList) merge(DATA, KEYS) # A B Value # 1 1 6 9 # 2 3 8 2

Edit: after the OP expressed his preference for a logical vector in the comments below, I would suggest one of the following.

Use merge:

df.in.df <- function(x, y) { common.names <- intersect(names(x), names(y)) idx <- seq_len(nrow(x)) x <- x[common.names] y <- y[common.names] x <- transform(x, .row.idx = idx) idx %in% merge(x, y)$.row.idx }

or interaction:

df.in.df <- function(x, y) { common.names <- intersect(names(x), names(y)) interaction(x[common.names]) %in% interaction(y[common.names]) }

In both cases:

df.in.df(DATA, KEYS) # [1] TRUE FALSE TRUE FALSE FALSE FALSE

Are you using sizeof(*h) to determine the number of List elements in an array?

sizeof(*h) returns the size of List. Since tostring() only get's a pointer to a List, it has no way of knowing how many elements are pointed to.

In any case, it appears you are then writing a string to a character array of this size. What does the size of List have to do with the number of elements in the array? What are you trying to do?

2413408 0 WebOrb - Serializing an object as a string

We have an Adobe Flex client talking to a .NET server using WebORB. Simplifying things, on the .NET side of things we have a struct that wraps a ulong like this:

public struct MyStruct { private ulong _val; public override string ToString() { return _val.ToString("x16"); } // Parse method }

And a class:

public class MyClass { public MyStruct Info { get; set; } }

I want the Flex client to treat MyStruct as a string. So that for the following server method:

public void DoStuff(int i, MyClass b);

It can call it as (C# here as I don't know Flex)

MyClass c = new MyClass(); c.Info = "1234567890ABCDEF" DoStuff(1, c)

I've tried playing with custom WebORB serializers, but the documentation is a bit scarce. Is this possible? If so how?

I think I can work out how to serialize it, but not the other way. Do I need to write a Custom Serializer on the the Flex end as well?

From the install steps you've listed it sounds like you're missing a few steps.

Definitely revisit the Haystack setup instructions with a particular eye to looking at the Create a Search Site and Creating Indexes sections.

The long and short is you seem to be missing an indexes file. Haystack registers a bunch of stuff from your indexes when it is first included, so that explains why you're getting errors from haystack.__init__

Add a file called 'search_indexes.py' to your application directory. This file contains a list of the indexes you want to generate for different models. A simple example would be:

from haystack.indexes import * from haystack import site from myapp.models import MyModel class MyModelIndex(SearchIndex): text = CharField(document=True, use_template=True) def prepare(self, obj): self.prepared_data = super(MyModelIndex, self).prepare(obj) self.prepared_data['text'] = obj.my_field site.register(MyModel, MyModelIndex)

This will add a free text search field called 'text' to your index. When you search for free text without a field to search specified, haystack will search this field by default. The property my_field from the model MyModel is added to this text field and is made searchable. This could, for example, be the name of the model or some appropriate text field. The example is a little naive, but it will do for now to help you get something up and running, and you can then read up a bit and expand it.

The call site.register registers this index against the model MyModel so haystack can discover it.

You'll also need a file called search_sites.py (Name as per your settings) in your project directory to point to the index files you've just made. Adding the following will make it look through your apps and auto-discover any indexes you've registered.

import haystack haystack.autodiscover()

6939243 0 TFS Integration Platform: How to map users with the SVN adapter?

I want to migrate sourcecode from SVN to TFS2010 using the TFS Integration Platform.

I am using the Codeplex Release from March 25th of the TFS Integration Platform.

The SVN Adapter basically works. I can get the sourcecode from the SVN repository into TFS, including the full history (all revisions from SVN).

However all the checkins into TFS are done as the user that is running the TFS Integration Platform Shell.

I was wondering how I can configure a mapping of SVN users to TFS users. My SVN users are not ActiveDirectory of configured as Windows users.

I would just like to specify an explicit mapping for each SVN user to an existing TFS user.

On the web I found several hints at using a <UserMappings> element or a <ValueMap name="UserMap"> or an <AliasMappings> ... but there seems no concrete example how to configure that with the SVN adapter. All my experiments are failing...

Is this supposed to work with the SVN adapter?

Could somebody give me a hint or a pointer how to configure this mapping?

If you are using:

<%= render 'form', locals: {record: @record} %>

then, you will need to use variable record instead of @record in your _form.html.erb as:

<% unless record.nil? %>

Description:

locals: {record: @record} means, @record's value will be accessible by using record in the partial being rendered.

12550659 0 Make awk interpret one line at a time from variable

I'm a completely new to shell scripting and bash. My question is how do I get awk to interpret a variable which contains linebreaks the same way as awk interpret the data from stdin?

Example:

fileData=`cat /path/to/file` echo $fileData | awk '{print $1}'

The code above results in the following error message: awk: program limit exceeded: maximum number of fields size=32767 which obviously means that awk interprets all the lines in $fileData at the same time and not one line at a time.

I currrently try to run Docx4j in WebLogic Server 12c. WebLogic Server 12c comes with EclipseLink 2.3.2.

There is a similar Post describing the situation which unfortunately yield no answer.

Docx4j does not work with the JAXB (MOXy) implementation which is part of EclipseLink 2.3.2. I got Docx4j running standalone with EclipseLink 2.5. So I am very confident that using EclipseLink 2.5 with Weblogic Server 12c will solve the issue with Docx4j.

How can I replace the EclipseLink Vesion 2.3.2 the WebLogic Server 12c is running on with EclipseLink Version 2.5?

18353167 0 App design to MVC pattern

The answer on this question Swing: how to get container bind to JRadioButton? made me think of MVC in a simple app design. I describe the general idea of an app and my thoughts on MVC pattern for this case.

Small app description:

This app lets user to add simple records that consist of name and description. After pressing "add" button, they are added to the panel as two labels and radio button to let edit the record. User can save his list in a profile (serialize to xml, properties or somewhere else).

My thoughts on how to apply MVC here:

Model

Record with name and description fields
Profile with serialization mechanism

View

Panel that contains multiple panels (records list) - one for each record (radio button + 2 labels for name and description data)

Controller

2 text boxes with labels and a button to add record
button to edit a record

At the moment there's no code samples (I'll provide them a little bit later). I don't want to hurry, I want to understand whether I go in a right MVC direction or something should be changed before implementation.

Updated

It seems that your TFS Build Service account has no required permission to access the signingKey.pfx on build agent machine. Make sure you have this file on build agent machine first.

Then follow below steps:

Log on the build agent as your local build service account (Better have Administrator permission)
Open a visual studio command prompt and navigate to the directory the key is stored in
Type command sn –i signingKey.pfx VS_KEY_EFCA4C5B6DFD4B4F(Ensure that you use the key name appearing in the error message)
When prompted for a password type the password for the pfx file
Then rebuild it

Note: If you are not running Visual Studio as an Administrator try doing that as well.

More details you can reference the answer from Brandon Manchester Cannot import the keyfile 'blah.pfx' - error 'The keyfile may be password protected'

An important thing to notice: strcpy's behavior is undefined (see C99 7.23.2.3:2) when provided with overlapping source and destination. So what you're doing, no matter how the output looks, is basically not guaranteed to work unless your C implementation's documentation states otherwise.

Use memmove when moving data within a string.

You should also be very careful in how you declare your string. The code you provided is correct:

char string[] = "foo";

The string is an array of characters, initialized to contain four elements: 'f', 'o', 'o', '\0'.

But, very similar code would be incorrect:

char * string = "foo";

What this code does is initializes a char pointer to the address of a constant string literal "foo". A correct version would be:

const char * string = "foo";

If you tried to modify such a string, the compiler would rightly complain.

I presume when you say it hides the right answer button is when the answer is "2", since by your giveHint function it will remove index 1 from answers array which is "2".

Change your giveHint removeAtIndex will do the trick.

Instructions to Remote Debug MS SQL Stored Procedures within Visual Studio 2005

Launch Visual Studio (If you're running from Vista, Run As Administrator)
Within Visual Studio 2005 click View->Server Explorer, which you'll notice brings up a panel with a Data Connections element.
Right click on Data Connections and select Add Connection
Ensure the Data Source is set to SqlClient.
Fill out the Server connection information, filling in the database name where the stored procedure that you wish to debug lives.
Once a successful connection is made you'll notice the a tree for the database is populated that gives you the list of Tables, Views, Stored Procedures, Functions, etc.
Expand Stored Procedures, finding the one you wish to debug and right click on it and select Step Into Stored Procedure.
If the stored procedure has parameters a dialog will come up and you can specify what those parameters are.
At this point, depending on your firewall settings and what not, you maybe be prompted to make modifications to your firewall to allow for the necessary ports to be opened up. However, Visual Studio seems to handle this for you.
Once completed, Visual Studio should place you at the beginning of the stored procedure so you can starting the act of debugging!

Happy Debugging!

Firstly, I agree with the previous answer that you should be using the strict equality operator. Secondly, you are using incorrect syntax - where you have data-bind should be ko, i.e.:

<!-- ko if: header.current_collection.url_type === 'stories' --> <p>text</p> <!-- /ko -->

15394450 0 onDraw() not being called

I am working on fixing someone's Android app. It was originally made for 2.1 and I am trying to get it work to 4.0+. Unfortunately the person who made the app is not around so I am stuck with his code.

The app implements custom sliders, a horizontal and vertical. I got the vertical slider fixed, but I cannot get the horizontal slider to work. It is not calling onDraw(): When the view loads, onDraw() gets called and I see both of my sliders initialized, then when I move my horizontal slider it moves and calls onDraw() once, but never again will it call it, unlike the vertical slider which does call it.

Here is the code:

8982416 0 How to publish Actions to Facebook Graph API with parameters in call URL

To begin, Ive spent several hours looking for an answer and have come CLOSE but havent found a full answer.

So Im trying to publish actions using Facebook's Graph API and want to send parameters in the URL when initially calling it with the Facebook Javascript SDK.

Here is a call that WORKS:

 function postNewAction() { passString = '&object=http://mysite.com/appnamespace/object.php'; FB.api('/me/APP_NAMESPACE:ACTION' + passString,'post', function(response) { if (!response || response.error) { alert(response.error.message); } else { alert('Post was successful! Action ID: ' + response.id); } } ); }

With object.php looking like so:

 <head xmlns:enemysearch="http://apps.facebook.com/APP_NAMESPACE/ns#"> <meta property="fb:app_id" content="APP_ID" /> <meta property="og:type" content="APP_NAMESPACE:object" /> <meta property="og:title" content="some title" /> <meta property="og:description" content="some description"/> <meta property="og:locale" content="en_US" /> <meta property="og:url" content="http://www.mysite.com/appnamespace/object.php"/> </head>

So obviously the above will post some sort of action to Facebook that will be the same every time object.php is called.

This is not ideal for my purposes.

So I took a look at this thread and it helped but as you will see, doesnt answer everything.

So if I change object.php to include dynamically generated meta tags by using content from either GET or POST and use the Object Debugger with a matching URL format to the one provided in og:url, the debugger shows everything as working as I would expect with now warnings. Here is what the dynamically generated object.php looks like:

 <?php if(count($_GET) > 0) { $userName = (int)$_GET['userName']; } else { $userName = (int)$_POST['userName']; } ?> <head xmlns:enemysearch="http://apps.facebook.com/APP_NAMESPACE/ns#"> <meta property="fb:app_id" content="APP_ID" /> <meta property="og:type" content="APP_NAMESPACE:object" /> <meta property="og:title" content=" <?php echo $userName; ?>" /> <meta property="og:description" content="Click to view more from <?php echo $userName; ?>"/> <meta property="og:locale" content="en_US" /> <meta property="og:url" content="http://mysite.com/appnamespace/object.php?userName=<?php echo $userName; ?>"/> </head>

SO, what I need to know is how to send url parameters in the initial call. If I use the debugger and enter something to the effect of http://mysite.com/appnamespace/object.php?userName=Brad everything works fine and the meta tags return content with that name inside of them. However if I try to pass the same url in the Javascript Call, it returns an error saying that my meta property og:type needs to be 'APP_NAMESPACE:object' (which as you see above, is what I have) instead of 'website' (which as you can see above, is something I am not using). Here is what that broken call would look like:

 function postNewAction(userName) { passString = '&object=http://mysite.com/appnamespace/object.php?userName=' + userName; FB.api('/me/APP_NAMESPACE:ACTION' + passString,'post', function(response) { if (!response || response.error) { alert(response.error.message); } else { alert('Post was successful! Action ID: ' + response.id); } } ); }

To be clear, the userName variable is only for example.

Any thoughts?

Absurd over-generalization:

Every Traversable instance supports a horrible hack implementing reverse. There may be a cleaner or more efficient way to do this; I'm not sure.

10263001 0 jquery form validation using groups

I have an order form, one part of the form is the address. It contains Company, Street-Address, ZIP, Town, Country with a simple jquery form validation with every field required, and ZIP validated for number. Now what I want is to group them and only have one field showing "valid address" on success, or "address wrong" on error.

This is a part of my js code:

$("#pageform").validate( { messages: { company_from: addressError, //addressError is a JS var for the error message street_from: addressError, zip_from: addressError, town_from: addressError, country_from: addressError }, groups: { from: "company_from street_from zip_from town_from country_from" }, errorPlacement: function(error, element) { if (element.attr("name") == "company_from" || element.attr("name") == "street_from" || element.attr("name") == "zip_from" || element.attr("name") == "town_from" || element.attr("name") == "country_from" ) { $("#error_from").append(error); } }, success: function(label) { var attribute = $(label[0]).attr("for"); $(".err-ok-" + attribute + " .ok").css("display", "block").css("visibility", "visible"); } } );

This is a part of the corresponding HTML code:

<input type="text" name="company_from" id="company_from" class="required default input-s8" maxlength="255" /> <input type="text" name="street_from" id="street_from" class="required default input-s8" maxlength="255" /> <input type="text" name="zip_from" id="zip_from" class="required digits default input-s8" maxlength="5" onblur="checkCalculation()" /> <input type="text" name="town_from" id="town_from" class="required default input-s8" maxlength="255" /> <!-- and a select list for the country -->

You do not need to take a closer look on how I show the error and so on, my problem is, that I do not know when to show the error label and when the success label. When I enter a letter for the ZIP code, my errorPlacement function and the success function is called (and the errorPlacement first), so I guess it's always calling the success if there is at least one field correct.

Please ask if there are any questions, and I am pretty sure there are... :-)

public interface NullCheckable { boolean areAllPropertiesNull(); }

Then each class you want to be able to check implements this interface with the appropriate method e.g.

public class Class1 implements NullCheckable { private Object property1; public Object getProperty1() { return property1; } @Override public boolean areAllPropertiesNull() { return property1 == null; } }

I found the quickest solution was to create a sql database with different tables for each type( Vehicles, Lookups etc.). When I just loaded all the data in and queried with a bunch of joins it took over a minute. But by creating foreign key references, indexes and adding primary keys to the table I got it down to less than a second. So I create the query from my c# Code and get back an object that contains all the information I need from each table.

Can it be simply because call to rate_limit_status.json also counts? What if you do

client.search("baeza") client.search("baeza") client.search("baeza") puts Twitter::REST::Request.new(client, :get, 'https://api.twitter.com/1.1/application/rate_limit_status.json', resources: "search").perform

Will it return 176?

Update - call to rate_limit_status should not affect limits, but would be interesting to see the outcome of the suggested calls anyway.

Update 2

Gem fetches only first page by default, no matter of results count. Getting next page(s) is under your control. See here - fetch_next_page is private method, called by "each" method of enumerator here - so if you start iterating over search results and pass through all first page results. When you just made a request (called search) - it only fetches first page (one query).

Also, gem sets count parameter for API search request to 100 (max allowed) if not specified by default - here for constant and here for setting it

Make the first function call the next one and add this to your HTML :

 <input> type=button onclick="validateForm(); return false;" </input>

Putting 'return false' will prevent redirection and will give time for your function to execute.

function validateForm(){ var email = document.forms["form"]["Email"].value; if(email == null || email == ""){ alert("Email must be filled out"); return false; } else redirect(); }

Additionally, I'd recommend to abstain from putting any code in your HTML. It is considered a "bad practice". However, if you still want to put your code, it'll be more appropriate to put it in the form as an "onsubmit" action:

<form onsubmit="validateForm()">

If you want the function to execute when the submit button is clicked, you can just add an event listener in your script and an id to your button, like this:

var button = document.getElementById("submit"); button.onclick = function validateForm() { /*same code as above..*/ };

Hope it helps!

22920020 0 Dojo ToggleButton Check Icon doesn't update

I am defining a toggle button in HTML and then updating it's checked state in JavaScript based on another toggle button.

Toggle Button: <input type="checkbox" dojoType="dijit.form.ToggleButton" iconClass="dijitCheckBoxIcon" label="Assigned Work" id="AssignedWork" >

When the app runs I want this toggle button to be un-checked.

I can successfully call the checked property like this:

Registry.byId("AssignedWork").checked = true;

However my toggle button's icon isn't updating to indicate the "Check". When my mouse cursor hovers over the toggle button the button refreshes and shows the check mark. Is there a way to get the check icon to turn on with the .checked property?

3914280 0 Is there a way to make Netbeans file uploads not fail on a single error?

Is there a way to make Netbeans's FTP uploads less error sensitive(reconnect and retry on error)?

It is simply unable to handle large amounts of files. If I upload 1000 files and there is some sort of failure at the 400th file, it will fail for the rest of the files, and it will not record the files that failed. So I will have to upload ALL the files again, even the ones that uploaded successfully on the previous attempt, but it will fail agan again and again.

20535653 0 Resuse of Async task code in my various file

I want to create an class file for Async task operation and from creating the object of that class file i want to access these method of async task with no of different class files with different parameters.

Methods of Async task include:-

OnPreExecute()-Want to start progress dialog same for each class.

doInbackground()-Want to perform background operation(like getting data from server) means passing parameter different for each class.

onPostExecute()-Dismiss the progress dialog and update the UI differnt for each class.

Nw i m writing the async task in my every class as inner class like following:-

class loaddata extends AsyncTask<String, String, String> { @Override protected void onPreExecute() { super.onPreExecute(); pDialog = new ProgressDialog(AddNewLineitem.this); pDialog.setMessage("Loading Data. Please wait..."); pDialog.setIndeterminate(false); pDialog.setCancelable(true); pDialog.setOnCancelListener(new OnCancelListener() { @Override public void onCancel(DialogInterface dialog) { } }); pDialog.show(); } @Override protected String doInBackground(String... params) { try { List<NameValuePair> params1 = new ArrayList<NameValuePair>(); JSONObject json = jparser.makeHttpRequest(url_foralldropdowns, "GET", params1); compoment = json.getJSONArray(COMPONENT_CODE); for (int i = 1; i < compoment.length(); i++) { JSONObject c = compoment.getJSONObject(i); String code = c.getString(CODE); list_compoment.add(code); } } catch (Exception e) { e.printStackTrace(); } return null; } protected void onPostExecute(String file_url) { loadSpinnerData(); pDialog.dismiss(); } }

And JSON parser class is as follows:-

public class JSONParser { static InputStream is = null; static JSONObject jObj = null; static String json = ""; // constructor public JSONParser() { } // function get json from url // by making HTTP POST or GET mehtod public JSONObject makeHttpRequest(String url, String method, List<NameValuePair> params) { // Making HTTP request try { // check for request method if (method == "POST") { // request method is POST // defaultHttpClient DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); httpPost.setEntity(new UrlEncodedFormEntity(params)); HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); is = httpEntity.getContent(); } else if (method == "GET") { // request method is GET DefaultHttpClient httpClient = new DefaultHttpClient(); String paramString = URLEncodedUtils.format(params, "utf-8"); url += "?" + paramString; HttpGet httpGet = new HttpGet(url); HttpResponse httpResponse = httpClient.execute(httpGet); HttpEntity httpEntity = httpResponse.getEntity(); is = httpEntity.getContent(); } } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } try { BufferedReader reader = new BufferedReader(new InputStreamReader( is, "iso-8859-1"), 8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); json = sb.toString(); } catch (Exception e) { Log.e("Buffer Error", "Error converting result " + e.toString()); } // try parse the string to a JSON object try { jObj = new JSONObject(json); } catch (JSONException e) { Log.e("JSON Parser", "Error parsing data " + e.toString()); } // return JSON String return jObj; } }

And in oncreate() i call this and it works fine:-

new loaddata().execute();

Please Help yourself..Thanks in advance

Those are macros declarations.

Whenever you have lowByte(0x1234) in your code, it will be replaced with the right part of the macro, substituting arguments with their values, that is ((uint8_t) ((0x1234) & 0xff)).

This step is performed by the preprocessor prior to compilation.

9611595 0 Why is += valid temporaries in standard library?

When I attempt to compile the following on ideone:

class X { public: friend X& operator+=(X& x, const X& y); }; X& operator+=(X& x, const X& y) { return x; } int main() { X() += X(); }

As expected, this throws a compile error, because you can't pass a temporary to a non const reference.

However, the following compiles successfully on ideone:

std::string() += std::string();

Shouldn't this error like my example above?

Edit:

If std::string() defines += as a member operation, why does it do this when such usage allows the left hand side to be a temporary? Why not define it as I have above and avoid the reference to temporary issues?

You could use sf::SoundBuffer with loadFromSamples (see the documentation).

The representation of a sound in memory is basically a large array of integers that gives the amplitude of the signal at a given time. You can provide your own array to a sf::SoundBuffer with the correct parameters, and that would give you your programmatically generated sound.

For manipulation of sound, volume etc I can't help you though, you'll have to search for the maths behind signal processing and such.

20941128 0 How to feed a custom ImageSource to Image in XAML

One way to set an ImageSource for Image in XAML is like this:

<Image Width="75" Height="75"> <Image.Source> <BitmapImage UriSource={Binding Uri} DecodePixelWidth="75" DecodePixelHeight="75" /> <Image.Source> </Image>

This code contains a nice optimization, since a potentially large bitmap will be decoded to 75x75 pixels.

I'd like to be able to replace BitmapImage with my custom class like this:

<Image Width="75" Height="75"> <Image.Source> <custom:PictureBitmap Picture={Binding Picture} Width="75" Height="75" /> <Image.Source> </Image>

My application implements the Picture class, which maps to a database table. Picture class has everything I need to create an instance of BitmapImage. So PictureBitmap is essentially an adapter for the BitmapImage.

Here is how I started:

public class PictureBitmap : BitmapSource { // TODO: create Picture Dependency Property // TODO: create a BitmapImage from Picture // TODO: implement abstract methods by delegating calls to BitmapImage }

Although BitmapSource is abstract, the API reference doesn't explain how to implement it.

Does anyone know how to feed a custom object to Image.Source?

My app supports Windows Phone Mango (7.5) and up.

Thanks!

A jdbc statement is one single sql instruction.

Here you try to run multiple sql instructions in one statement. You must split your sql on ; and create an execute one statement for each instruction.

Call the function and save the result in a variable:

$result = GetProductsByCategory($categoryID);

then inside the function:

$productsResult = $conn->query($sql); return $productsResult;

then your while loop should use this returned result (i.e., $result):

while ($row = $result->fetch_assoc()) { ... }

Observations,

Count_List() should count each element on list, your version only counts starting at the second item on the list. And it should always return an int,

int Count_List(Library *Head) { int count = 0; Library *Tmp = Head; if(!Tmp) return(count); while(Tmp != NULL) { count++; Tmp = Tmp->next; } return(count); }

Inside Read_File() you call Create_List(Entry,Head), but your function signature for Create_List(Head,Entry); which do you intend? Probably (Head,Entry). Use fgets and sscanf to Read_File,

Library * Read_File(FILE *fp) { Library *Head, *Entry; Head = Entry = NULL; char genre[100], band[100], album[100]; float rating; char line[100]; while(fgets(line,sizeof(line),fp) { sscanf(line,"%s %s %s %f", genre, band, album, &rating); Entry = Create_Album(genre, band, album, rating); Head = Create_List(Head,Entry); } return Head; }

Looking at Create_List(), you seem to be implementing the List as a stack (push Entry onto head of list),

Library * Create_List(Library *Head, Library *Entry) { if(!Head) return Entry; Entry->next = Head; return Entry; }

Create_Album() needs to check for successful malloc before assigning values to member variables,

 Library *Entry=NULL; if( !(Entry=(Library*)malloc(sizeof(Library))) ) { printf("error creating album\n");fflush(stdout); return Entry; }

Speaking of Library struct, you declare the members genre, band, album as pointers, but you need space to copy memory, example,

typedef struct library { char genre[50]; char band[50]; char album[50]; float rating; struct library *next; }Library;

My suggestion would be to build constructor and destructor functions LibraryNew, LibraryDel.

Check for (argc<2) arguments (your message says not enough, instead of need 2,

 if(argc < 2) { printf("Not enough arguments.\n"); return 0; }

And that fixes the biggest problems,

./library music.x 2 line:Rock Antrax Party 1.2 Rock,Antrax,Party,1.200000 Rock,Antrax,Party,1.200000 added: Rock,Antrax,Party,1.200000 Rock Antrax Party 1.20 Rock Antrax Party 1.20 Which genre would you like to delete?

With Java 7, it's as simple as:

final String EoL = System.getProperty("line.separator"); List<String> lines = Files.readAllLines(Paths.get(fileName), Charset.defaultCharset()); StringBuilder sb = new StringBuilder(); for (String line : lines) { sb.append(line).append(EoL); } final String content = sb.toString();

However, it does havea few minor caveats (like handling files that does not fit into the memory).

I would suggest taking a look on corresponding section in the official Java tutorial (that's also the case if you have a prior Java).

As others pointed out, you might find sime 3rd party libraries useful (like Apache commons I/O or Guava).

Here is a working version with some changes from your original code. As pointed out in the other answer, there are a few errors in your code. In addition, I changed textOutput to htmlOutput. In server.R, I put all code inside the observeEvent environment.

In general, your method in your R script needs to return something suitable for process in server.R. For example, in this case, it returns a string, which server.R renders as text, and ui.R in turn renders as HTML.

Any variable/data that is accessible in server.R (including any files that it source) can be displayed in the ui. What you need is (1) a suitable render method to render this data in server.R (2) a suitable output container to hold the output display in ui.R

ui.R

library(shiny) shinyUI(fluidPage( headerPanel("Inputting from Interface to Script"), sidebarPanel( #'a' input numericInput(inputId = "a", label = h4("Enter a:"), value = 3), numericInput(inputId = "b", label = h4("Enter b:"), value = 4), actionButton(inputId = "input_action", label = "Show Inputs")), mainPanel( h2("Input Elements"), htmlOutput("td")), # use dataTableOuput to display the result of renderDataTable. Just like the render methods, there are many output methods available for different kind of outputs. See Shiny documentation. dataTableOutput("table") ))

server.R

library(shiny) source("mathops.R") shinyServer(function(input, output) { observeEvent(input$input_action, { a = input$a b = input$b output$td <- renderText({ mathops(a,b) }) }) # Use renderDataTable to convert mat2 to a displayable object. There are many other render methods for different kind of data and output, you can find them in Shiny documentation output$table <- renderDataTable(data.frame(mat2)) })

mathops.R

mathops <- function(a,b) { return(paste0("Addition of two number is: ", a+b, br(), "Multiplication of two number is: ", a*b)) } mat1 <- matrix(sample(1:16), ncol=4) mat2 <- matrix(sample(1:25), ncol=5)

So after two days of research I cant find a proper solution to this issue i managed to bypass it by setting the cell frame in layoutAttributesForElementsInRect like this:

 UICollectionViewCell* cell = [self.collectionView cellForItemAtIndexPath:[NSIndexPath indexPathForItem:[attributesForElementsInRect indexOfObject:attributes] inSection:0]]; if (!CGRectEqualToRect(cell.frame, refAttributes.frame)) cell.frame = refAttributes.frame;

this is the complete function

- (NSArray *)layoutAttributesForElementsInRect:(CGRect)rect { NSArray* attributesForElementsInRect = [super layoutAttributesForElementsInRect:rect]; NSMutableArray* newAttributesForElementsInRect = [[NSMutableArray alloc] init]; // use a value to keep track of left margin CGFloat leftMargin = 0.0; for (id attributes in attributesForElementsInRect) { UICollectionViewLayoutAttributes* refAttributes = attributes; // assign value if next row if (refAttributes.frame.origin.x == self.sectionInset.left) { leftMargin = self.sectionInset.left; } else { // set x position of attributes to current margin CGRect newLeftAlignedFrame = refAttributes.frame; newLeftAlignedFrame.origin.x = leftMargin; refAttributes.frame = newLeftAlignedFrame; } // calculate new value for current margin leftMargin += refAttributes.frame.size.width + 8; [newAttributesForElementsInRect addObject:refAttributes]; UICollectionViewCell* cell = [self.collectionView cellForItemAtIndexPath:[NSIndexPath indexPathForItem:[attributesForElementsInRect indexOfObject:attributes] inSection:0]]; if (!CGRectEqualToRect(cell.frame, refAttributes.frame)) cell.frame = refAttributes.frame; } }

Hope this will help somebody or someone have a better solution

Edited after reading Frans Bouma's answer, since my answer has been accepted and therefore moved to the top. Thanks, Frans.

GUIDs do make a good unique value, however due to their complex nature they're not really human-readable, which can make support difficult. If you're going to use GUIDs you might want to consider doing some performance analysis on bulk data operations before you make your choice. Take into account that if your primary key is "clustered" then GUIDs are not appropriate.

This is because a clustered index causes the rows to be physically re-ordered in the table on inserts/updates. Since GUIDs are random, every insert would require actual rows in the table to be moved to make way for the new row.

Personally I like to have two "keys" on my data:

1) Primary key
Unique, numeric values with a clustered primary key. This is my system's internal ID for each row, and is used to uniquely identify a row and in foreign keys.

Identity can cause trouble if you're using database replication (SQL Server will add a "rowguid" column automatically for merge-replicated tables) because the identity seed is maintained per server instance, and you'd get duplicates.

2) External Key/External ID/Business ID
Often it is also preferable to have the additional concept of an "external ID". This is often a character field with a unique constraint (possibly including another column e.g. customer identifier).

This would be the value used by external interfaces and would be exposed to customers (who do not recognise your internal values). This "business ID" allows customers to refer to your data using values that mean something to them.

20955706 0 JCL ICEMAN how many sort files are needed?

I am working with JCL and there is what is called an ICEMAN which is which is invoked when the IBM SORT utility DFSORT is used. DFSORT can be used to SORT, COPY or MERGE files, amongst other things. In the example below there the output is from a SORT. My question is how many sortwork (//SORTWK01 DD UNIT=SYSDA,SPACE=(CYL,30)) files are needed. They seem to me to always vary in number when I see them in JCL. Is there a formula for this to figure the size of how many SORTWKnns are needed?

38000800 0 NodeJS, Passport & Passport-Local

So I'm running into an issue authenticating using a local strategy. If I pass invalid credentials or anything unsuccessful, I get the appropriate error. However, if they authentication is successful, then I'm presented with a 404 error.

I've dug around, and the best idea I ran across was dropping the session storage (which is where it seems to be happening, while serializing the user). Anyone encounter an issue like this?

Here's some of the code, if you need any other sections of code, let me know I'll gladly provide it.

My Passport configuration:

var passport = require('passport'), User = require('mongoose').model('User'); module.exports = function () { passport.serializeUser(function (user, done) { done(null, user.id); }); passport.deserializeUser(function (id, done) { User.findOne({ _id: id }, '-password -salt -__v', function (err, user) { done(err, user); }); }); require('./strategies/local')(); };

My Local Strategy configuration:

var passport = require('passport'), LocalStrategy = require('passport-local').Strategy, User = require('mongoose').model('User'); module.exports = function () { passport.use(new LocalStrategy({ usernameField: 'email' }, function (email, password, done) { User.findOne({email: email}, function (err, user) { if (err) { return done(err); } if(!user || !user.active || !user.authenticate(password)) { return done(null, false, { message: 'Authentication Failed'}); } return done(null, user); }); })); };

All other methods work, I can query the DB to find the user, I have stepped through matching the hashed password with the provided password, it all seems to happen fine and I get a user at the end of the LocalStrategy (I make it to the final done(null, user). In the serializeUser() done(null, user.id) something happens. I've tried stepping through it, but what I end up getting into seems fairly obfuscated (or I'm too dumb to understand it) so I can't tell what's actually happening.

None of those are even remotely good ideas, although the first one is passable with some modifications. reinterpret_cast doesn't work the way you think it does, and I'm not sure what exactly you're trying to achieve with placement new. Store a smart pointer of some sort in the first one to avoid the obvious issues with lifetime, and the first option isn't bad.

There is a fourth option: just store the data in a struct, and provide whatever encapsulated access you desire.

struct data { data(int i_) : i(i_) { } int i; }; struct s { s(int i_) : i(i_) { } data i; };

Rereading your question, it appears as though maybe your intent is for this struct to be an internal detail of some larger object. In that case, the lifetime issues with the first solution are likely taken care of, so storing a raw pointer is less of a bad idea. Absent additional details, though, I still recommend the fourth option.

Your logic seams correct to me. But I wonder about a possible problem with registering for a UIKeyboardWillHideNotification every time your viewWillAppear. Try to register only once in viewDidLoad and unsubscribe in dealloc. I am thinking that maybe when you register again after you dismiss the modal view the Notification Center sends you an old notification. If you register once for a notification you will not get it more then it is posted.

34280807 0 My executable ruby gems don't work as expected

I followed this tutorial http://guides.rubygems.org/make-your-own-gem to figure out how to create ruby gems but I'm having trouble figuring out how to create an executable.

I originally thought I was making a mistake in my own code but the actual gem created with the tutorial itself doesn't seem to work as I expected. So I'll base my question around the actual gem from the tutorial itself.

If you bundle the exact gem from the tutorial (the gem is named hola) into a rails application and try to use the executable command hola, all you get are error messages:

$ rails hola spanish # => Error: Command 'hola' not recognized $ ruby hola spanish # => ruby: No such file or directory -- hola (LoadError) $ hola spanish # => -bash: hola: command not found

Even if I attempt to execute the command this way it doesn't seem to work:

$ ruby -Ilib ./bin/hola spanish # => ruby: No such file or directory -- ./bin/hola (LoadError)

The only time this seems to execute anything is when I'm inside the actual gem directory recreated by hand in the tutorial and type this:

$ ruby -Ilib ./bin/hola spanish # => hola mundo

But this is useless because the whole point of creating an executable is to be able to execute it within an actual project not the gem directory (ie: someone downloading your gem and being able to use it with a single executable keyword, like rake routes which then does something).

Can I bundle the hola gem from this official rubygems.org tutorial and use it as an executable in the way I was expecting to execute it, like this:

$ hola spanish # => hola mundo

If this is possible, how is it done?

There are a few of things I can see to improve this

Before looping, check if the substring is 0 length, if so return false (dont check every iteration)
Remove ALL == true's its basically comparing a boolean against a boolean
Use IndexOf to find the first character of your substring (return false if result of indexOf is -1) and then use this index as the starting value for i
I believe instead of the j variable you can just increment i but I've not tested this
```
if (FoundMatch) return true;

34894570 0 Pure virtual function which must set variable

recently i have read some about pure virtual function concept in c++ and i wonder, given following code:

class First { public: virtual void init() = 0; protected: bool initialized; }; class Second : public First { public: void init() { ((*someting*) ? (initialized=true) : (initialized=false)); };

if creator of First class wanted to ensure the implementation of init() MUST set initialized variable either true or false how can they do that? Is there an option to enforce implementation of pure virtual function to set any variable inherited from base class?

If you are using Chrome, you should use the "Timeline" to record the memory usage. Launch the timeline, then wait for the page to refresh a few times, and then stop the timeline and have a look at the results. If you see the line keeping increasing, that means your objects in memory (or the DOM nodes) are never released and garbage collected.

I have never used document.open/write myself so I do not know if that can cause issues with garbage collection, but I suspect it does.

If your detect clearly a memory lak using the Timeline, then open the "Profiles" tab and take a Heat snapshot before and after a page reload, then use "comparison" to see what have changed and how much bigger your memory impact is. If for instance your old compiled code (or obejct references) is still there, plus the new one, then it explains your leak.

You should not place the outlet in the Application Delegate. Your app should contain a root view controller (created automatically if you're using a single view application template), which should handle anything related to the application's initial view. Once you have one, open the storyboard in the editor. Open an assistant editor using the buttons along the top, and use the drop-down menu at the top of the assistant editor to open up the header file of the controller. Select the scroll view, and control-drag from it into the controller's interface. Xcode will prompt you to make an outlet, allowing you to change the name. Let's use scrollView for the name. Select weak for the memory management, since it's already being retained by its superview. Xcode should automatically synthesize accessors, and now you can access the property using self.scrollView from within the controller's instance methods. Alternatively, you can select the scroll view and set its tag in the attributes inspector to any unique number, like 4. Then, you can use [self.view viewWithTag:4] to get a reference to it.

3390711 0 Start new activity from onClickListener

I have an EditText area that is not showing due to the keyboard covering it when the focus is on the EditText area. What I want to do is use a button to call an activity that will display a editable text area that overlays the main display and returns the value to the main activity which stores it in a separate class variable.

I added the activity to the main manifest xml.

I added an onClickListener to a button.

Here is some code:

TextEntryActivity class:

public class TextEntryActivity extends Activity{ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.text_entry); EditText edit = (EditText)findViewById(R.id.editable); getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND, WindowManager.LayoutParams.FLAG_BLUR_BEHIND); }

}

I have a separate XML file for the layout of the blurr.

Originally I had an onClickListerner for an onSave button that stored all the info:

 private View.OnClickListener onSave = new View.OnClickListener() { @Override public void onClick(View v) { Log.d(DEB_TAG, "INSIDE ONCLICK"); mCurrent = new Restaurant(); mCurrent.setName(mName.getText().toString()); mCurrent.setAddr(mAddr.getText().toString()); mCurrent.setDate(mDateDisplay.getText().toString()); mCurrent.setNotes(mNotes.getText().toString()); switch (mTypes.getCheckedRadioButtonId()){ case R.id.fast_food: mCurrent.setType("fast_food"); break;.........

The new activity is to provide a different view to add a "note"

Does this make sense? I am fairly new to this and know what I want to do in my head, but describing it can be a challenge.

Manu,

You can use VBScript templates (thought it is a good idea to start moving off this platform anyway) in your CMS backend and 64-bit on the front end, if your front end is .NET or Java.

What you cannot do is use COM on the Front-end (even if being called from .NET) and be on 64 bit, since the Tridion COM-based linking API is 32 bit only.

The .NET linking libraries and the Java linking libraries are 32 and 64 bit compatible, but not the COM libraries.

Hope this helps

656674 0 How efficient are IFrames?

If I built a page that consisted of IFrames on the order of hundreds, would this be incredibly slow, or would it behave similar to having a hundred divs?

The reason I ask is I'm looking for a nice recursive way to build a web page, where I can load sub-elements of a page as if they were complete pages of their own, with their own urls.

Thoughts? Opinions? Am I totally crazy to even be thinking it?

Edit: I just realized this would probably absolutely shred the network connection because it would have to make separate requests for each embedded frame, wouldn't it? And everything I've learned on making web pages more efficient to load is to reduce the number of http requests it needs to make.

Its very simple,

Suppose your Boolean field name is active,

create a method named status like

def status self.active ? "Yes" : "No" end

Use the status as a normal field in active admin show or index.

Logic depends as per your need and current DB structure. some possible solution could be
-If your path is fix, just store image name. and while creating full path join +
-If path is no fixed and storing path in DB, you can create one column more column and store unique id(any integer or alpanumeric as per logic but unique value) and use that unique value to replace path

I looked up in several places and concluded that one option for fixing this issue was to call this action only from a hyperlink and include target="_self". I can still add a ng-click attribute on the hyperlink and call code in my angular controller. This is not quite what I wanted to do because I wanted to make the call from my angular controller instead of from the hyperlink, but it will work.

The code I used is as follows:

using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm" })) { @Html.AntiForgeryToken() <ul data-ng-controller="accountController as acctCtrl"> <li><a data-ng-click="acctCtrl.logout()" href="javascript:document.getElementById('logoutForm').submit()" target="_self">Log off</a></li> </ul> }

Looks like there is no solution to this problem. The bug is aknowleged by microsoft, but its still not fixed in SSRS2008.

From the KB article (http://support.microsoft.com/kb/938943)

This behavior occurs because the Subreport control has an implicit KeepTogether property. By design, the KeepTogether property tries to keep content of a subreport on one page. Because of this behavior, the report engine creates blank space on the main report if the subreport does not fit on the same page as the main report. Then, the report engine creates the subreport on a new page.

The work around that they list is essentially 'don't use subreports'

If you're load-balancing, you're going to want the additional license to be the for the same platform as your existing license, because the point of load-balancers is to divide the work between multiple identical systems.

If you don't already have dependence on other Magento Enterprise Edition features, I would recommend against getting an Enterprise license if you are considering load-balancing. Because of the way Magento is licensed, you would require an additional Enterprise Edition license for each installation of Magento, and that includes each instance behind a load-balancer.

If you are considering expanding your infrastructure to include multiple instances of Magento, it is probably best to contact a Magento sales rep, as they will have more-specific information about licensing restrictions, and may be able to negotiate a package which suits your specific needs.

re.sub(r'^-+|-+$', lambda m: ' '*len(m.group()), '---ab---c-def--')

Explanation: the pattern matches 1 or more leading or trailing dashes; the substitution is best performed by a callable, which receives each match object -- so m.group() is the matched substring -- and returns the string that must replace it (as many spaces as there were characters in said substring, in this case).

12403797 0 IIS ARR (edge) cache (reverse proxy) - Upstream connection timeout issue

I am looking to use the IIS Application Request Routing as a reverse proxy cache. I've looked at several different options and come to the conclusion that it fits my needs the best. However, I've run into a sort of a dead end and could really use some input from someone who has more experience with the ARR module.

I have the following setup:

IIS ARR cache proxying requests to an internal server farm (weighted round robin loadbalancing to use the nearest origin server).
Keep alive is disabled in the IIS proxies.
The server farm consists of nginx webservers.
The IIS servers have RAM disk caches.

The use case is such that the edge servers will receive byte range requests and as it serves the content to the end user it will cache it (first 60 sec in memory cache, then write it to the RAM disk). So far everything is working correctly but when the next end user starts requesting the same byte ranges (that are now in the cache) I'm starting so see some weird behaviour between the IIS edges and the nginx origins: Upon the first byte range request (by the second end user) the IIS server opens a connection to the nginx origin which it does not use because it already has the requested segments in the cache. Since the connection isn't being used it's eventually closed by nginx due to a timeout (60 seconds). In the mean time the second end user is still requesting segments of the file that are in the cache. Then, and this is where the issue occurs, the second end user gets to a point in the file which is not in the cache. The behaviour I would expect from IIS here (being that keep-alive is disabled) is that it would open up a new connection to the origin and start fetching the part of the file that isn't in the cache. The behaviour I'm seeing however is that IIS tries to reuse the same connection it opened up in the beginning of the request (without realizing that it's been dropped by the origin). I've used the "Failed request tracing" to verify this as well and the result of that is that the IIS doesn't get an expected reply from the origin (since the connection no longer exists) and then, in turn, returns a 502.3 to the end user.

I've verified that increasing the connection timeout on the origins will "solve" the problem, but that is not really a viable solution as I would basically have to set an infinite timeout which may cause a whole new set of problems on the origin side. Is there any way of controlling how IIS handles this upstream connection (i.e. force it to open a new connection when it actually needs data from the origin, or to have it realize that the origin closed the connection)?

9093419 0 Accessing a variable from a file through a file that is required in said first file

I have an osCommerce-shop where I need to access a variable from inside an included php-file. For the sake of simplicity here is a short example of what I am talking about without anything related to osCommerce:

The file inside.php shows a picture and is only displayed on the homepage by being somehow required in index.php. Depending on what language has been selected it should show either picture 1 or 2. Currently only the first picture is displayed because I have no way of knowing which one should be used. Normally there is a $language_id variable which I can check if it is either 1 (english) or 2 (german). Unfortunately $language_id in inside.php is empty (or at least it looks like it) so I need a way to access the variable from index.php. Is there a way to do this without passing this variable or something like that? (Since it is a osCommerce-shop I am not sure how I could to that)

I hope what I tried to explain is somewhat understandable, if not, please ask and I'll try to clarify.

You either want to use union all or cross join. Use union all to get the results in two rows. Use cross join to get the results in two columns on the same row.

Here is an example for the cross join:

select sumcep, sumcepout from (SELECT SUM(tutar) as sumcep FROM cepbank WHERE tarih >= DATE(NOW()) ) t cross join (SELECT SUM(tutar) as sumcepout FROM cepbank_out WHERE tarih >= DATE(NOW()) ) t2

if you executing this query from your SSMS it means this other server is a linked server. then it should be no different to execute it from SSRS.

Yes it is right you can only add one server to your data source of your dataset whether its a shared data source or embedded.

But for instance if you have a data source pointing to say Server A when you executing queries which will be pulling data from Server A and also from server B you will Use fully Qualified name for the Objects from server B and two part name from server A.

something like this ...

SELECT * FROM Schema.Table_Name A INNER JOIN [ServerNameB].DataBase.Schema.TableName B ON A.ColumnA = B.ColumnA

obviously ServerB has to be a Linked Server.

Well, focus on this:

not re.match("c", "cat")

Here re.match("c", "cat") will return the "location of the object in memory", as you said. That's something not False.

So now, not re.match("c", "cat") will result in:

not not False

which results to:

False

Of course, this kind of thinking can be applied to logical conditions too, like a condition of an if statement.

I created the following one line solution avoiding multiple grep commands.

mysql -e "show databases;" | grep -Ev "Database|DatabaseToExclude1|DatabaseToExclude2" | xargs mysqldump --databases >mysql_dump_filename.sql

The -E in grep enables extended regex support which allowed to provide different matches separated by the pipe symbol "|". More options can be added to the mysqldump command. But only before the "--databases" parameter.

Little side note, i like to define the filename for the dump like this ...

... >mysql_dump_$(hostname)_$(date +%Y-%m-%d_%H-%M).sql

This will automatically ad the host name, date and time to the filename. :)

$array = array ( array ("Apple", 10), array("Ball", 5) ); $newarray = array(); foreach($array as $key => $val){ $tmparray = null; for($i = 1; $i <= $val[1]; $i++){ $tmparray[$i] = $val[0]; } $newarray[] = $tmparray; } print_r($newarray);

output:

Array ( [0] => Array ( [1] => Apple [2] => Apple [3] => Apple [4] => Apple [5] => Apple [6] => Apple [7] => Apple [8] => Apple [9] => Apple [10] => Apple ) [1] => Array ( [1] => Ball [2] => Ball [3] => Ball [4] => Ball [5] => Ball ) )

I need to switch on E_ALL and get the in the title mentioned warning, when I am exploding the $_GET string:

$input = explode( '/', $_GET['string'] );

Where does that come from? Is it the missing 3rd parameter (limit) for explode ? I want all entries.

Keep your code in a named function say - changeSize and call it in document.ready and window.resize as below:

DEMO

function changeSize(){ var fontSize = parseInt($("#container").width()/4)+"px"; $("#container span").css('font-size', fontSize); } $(document).ready(function() { changeSize(); $(window).resize(changeSize); });

or just once in document.ready() as below:

$(document).ready(function() { $(window).resize(changeSize).trigger('resize'); });

22753351 0 Comparisons with "Comparable" type variables in java?

I'm working on a University assignment, and I have to store elements in an array of the "Comparable" type. Eg:

protected Comparable storage[];

The elements that will be stored in this array are going to be either all integers, or all strings, but they're obviously created with the "Comparable" type as opposed to being created as int, or String.

What I'm having problems doing is comparing these values. At any given point, say the array is filled with "Comparable" elements that are actually integers, how can I compare them? I get that I have to use the compareTo() method, but what would the implementation look like? I've looked at the Java document online, and it has simply confused me even more.

Just to summarize, at any given point, the array might have "Comparable" type elements that are actually all integers, or all the elements will be Strings that were also made with the "Comparable" type. There's no mixing and matching of the integer and Strings in the array, it's just one or the other. I want to know how I would make the compareTo() method so that I can easily compare two elements in the array, or any two "Comparable" elements for that matter, and return say a 1, -1, or 0 if one is greater/less than the other

Would appreciate any help. I'm completely lost.

I agree with Gumbo, but here's how you can do it:

1.. Get the rewriterule to work in httpd.conf

As is clearly stated in the manual:

By default, mod_rewrite configuration settings from the main server context are not inherited by virtual hosts. To make the main server settings apply to virtual hosts, you must place the following directives in each section:
RewriteEngine On RewriteOptions Inherit 

2.. Detect if HTTPS is on, and if it is and the is is a secure page, rewrite to ...

This can be done by looking at %{HTTP_HOST}:

RewriteCond %{HTTPS} !=on RewriteRule /jquery\.min\.js$ https://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js [NC,R=permanent] RewriteCond %{HTTPS} =on RewriteRule /jquery\.min\.js$ http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js [NC,R=permanent]

You should also escape the dots and teh RewriteCond you use is unnecessary; you can do it in the RewriteRule.

3.. Each individual domain will still have it's own custom mod-rewrite rules. Which rules take precedence - global or per-domain? Do they combine? Is it ok if I have the "RewriteEngine On" directive in the global httpd.conf and then again in the vhost.conf?

It will be prepended to the virtual host's mod_rewrite configuration.

10821762 0 Using GDB for debugging netlink communication

I have a multi-threaded application that communicates with a kernel module using netlink sockets. One of the threads in user mode application works as a server and kernel module works as a client. Roughly the kernel code is as follows:

timeout = 3500; netlink_unicast(); wait: __set_current_state(TASK_INTERRUPTIBLE); timeout = schedule_timeout(timeout); __set_current_state(TASK_RUNNING); if (!timeout) { printk(KERN_ERR "No response received\n"); return -1; } if (message_status != UPDATED) { printk(KERN_ERR "Somebody woke us up before we got a reply. Time left %d\n", timeout); __set_current_state(TASK_INTERRUPTIBLE); goto wait; }

The message_status variable is updated in the netlink callback when the user mode application replies to this message. So basically the idea is to send a message and then wait at max timeout jiffies for the reply.

Now, using gdb, if I add a break point in any function that is called by netlink server thread in user mode, the break point is never hit and the kernel log is flooded with messages like

Somebody woke us up before we got a reply. Time left 3499

Somebody woke us up before we got a reply. Time left 3499

Somebody woke us up before we got a reply. Time left 3499

Somebody woke us up before we got a reply. Time left 3499

..

..

Somebody woke us up before we got a reply. Time left 3498

Until I finally get

No response received

What is causing the kernel thread to wake up from the timeout and how should I debug the user mode code?

32744717 0 How can I modify this to have a Google-like paging?

My controller class contains

var Paged = new PaginatedList<Products>(SideBar, page ?? 0, pageSize); if (Request.IsAjaxRequest()) { return PartialView("~/Views/Shared/_Grid.cshtml", Paged); } return View(Paged);

the PaginatedList is

public class PaginatedList<T> : List<T> { public int PageIndex { get; private set; } public int PageSize { get; private set; } public int TotalCount { get; private set; } public int TotalPages { get; private set; } public PaginatedList(IQueryable<T> source, int pageIndex, int pageSize) { PageIndex = pageIndex; PageSize = pageSize; TotalCount = source.Count(); TotalPages = (int)Math.Ceiling(TotalCount / (double)PageSize); this.AddRange(source.Skip(PageIndex * PageSize).Take(PageSize)); } public bool HasPreviousPage { get { return (PageIndex > 0); } } public bool HasNextPage { get { return (PageIndex + 1 < TotalPages); } } }

And my view is

<div class="pagination-container"> <nav class="pagination"> <ul> @for (int i = 0; i < Model.TotalPages; i++) { <li><a href="@Url.Action("Index", "Home", new { page = i})" class="@(i == Model.PageIndex ? "current-page" : "")">@(i + 1)</a></li> } </ul> </nav> <nav class="pagination-next-prev"> <ul> @if (Model.HasPreviousPage) { <li><a href="@Url.Action("Index", "Home", new { page = (Model.PageIndex - 1) })" class="prev"></a></li> } @if (Model.HasNextPage) { <li><a href="@Url.Action("Index", "Home", new { page = (Model.PageIndex + 1) })" class="next"></a></li> } </ul> </nav> <div> Page @(Model.PageIndex + 1) of @Model.TotalPages </div> </div>

One problem with the view above, is that it creates numeric pages equal to the page sizes within model. If the model has 6 pages the result is

What will happen if i have 100 Model.Pages ?

You can put ftplugin directory with filetype-specific settings inside .vim directory

.vim └── ftplugin └── ruby.vim └── markdown.vim

And keep your settings there. The are applied when file with corresponding filetype is opened.

Also, you might need to have filetype detection(if not detected properly). You can put this to your .vimrc

autocmd BufNewFile,BufRead *.markdown,*.md,*.mdown,*.mkd,*.mkdn set ft=markdown

Or, put it into ftdetect directory

.vim └── ftdetect └── markdown.vim

9787934 0 Firewall blocking/unblocking a port

I have an app installed on a server with windows 2008 R2 OS and hosted it on port 8080 (used apache tomcat for this).. I'm able to access the app through the URL..

Now, the problem is that I'm unable to access the URL (I mean app) from any other LAN connected machines.

After some exploration, I turned off the firewall of that server and I was able to access the app from other LAN connected machines..

I came to know the problem i.e Firewall is blocking that port 8080..

I can turn off the firewall, but it is not recommended right.. my requirement is to turn on the firewall and make this app accessible from any other LAN connected machine... I think I need to make that port open/something like that, but I don't have any idea regarding this.. no network admin is available as of now, so had to do it myself :( Kindly help me regarding this...

Thanks in advance!! :)

PS: I cannot download/install any other software's on that server, please suggest some way which can happen via command prompt/some settings to access that port from other LAN connected machines

P stands for package and E for Entity. So you can use regular expressions (like me in the extracting function) to extract the data you want.

 proc get_dependency_list_of_entity { lib entity } { set vdir_data [ vdir -lib $lib -prop dpnd $entity ] set match [extracting $vdir_data "^ *Depends on: (.+)"] ... } ... }

On the irony side, I am currently updating the SCSF documentation for ClickOnce deployment for .NET 4.0, and now I know exactly what the problem it.

First, you want to publish to a disk location, not directly to the webserver. So do that, and then copy the dll's you want to add to the deployment into the version folder with the application manifest (.manifest). Rename them yourself -- just add .deploy on the end.

Bring up MageUI and open the application manifest in that folder, then uncheck the box that says "add .deploy to the file names". Click "populate".

Then remove the deployment manifest from the list; it's called something like appname.application. You don't want it to be included in the manifest's list of files.

Now you can save and sign the application manifest. Then without exiting mageUI, open the deployment manifest that is in the root folder (NOT the one in the version folder). Click on "Application Reference", then click Select Manifest. Dig down to the application manifest in the version folder that you just signed and select it. Then just save and sign the deployment manifest. It puts a relative path in there, so if you modify the .application file in the version folder, it won't work right when deployed.

Now take that .application file from the root folder and copy it into the version folder (replacing the one that's there) so you have the right copy for that version in case you need it later.

Now copy the whole shebang out to the webserver. it should work.

When doing remote development, I use screen which provides multiple virtual remote terminals available at the press of a couple of keys. This is indispensable for me. Not only does it provide virtual terminals, but your session is preserved on the server if your connection drops for any reason.

See the GNU Screen Survival Guide question for more information about getting started with screen.

I usually have one terminal open for source control operations, one for editing, one for compiling (I just have to switch to it and hit UpArrow+Enter), and one for debugging. Depending on the environment and application I'm working on, I may have more or fewer than this, but that's the general layout.

28834992 0 setOnClickFillInIntent Error Handling

I have made an appWidget with a collection view. And in order to handle a click event on each view of the collection view, I used 'setPendingIntentTemplate' and 'setOnClickFillInIntent'. It is working fine in a normal case. It opens up the target activity by sending the intent upon click. But if an invalid uri (it is just not a valid uri for the target activity, but in syntax, it is a valid uri.) is injected to the intent for it, the widget just simply doesn't handle the click event. It doesn't throw any exception or return any error.

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(link); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); view.setOnClickFillInIntent(R.id.image, intent);

Is there any way to catch this error (the click event is not being handled due to the intent with an invalid uri)? - So that, I can switch to different code to handle the situation.

You could do it either inside the controller itself:

public function update(Request $request) { // Get the current users IP address and add it to the request $request->merge(['ip_address' => $_SERVER['REMOTE_ADDR']]); // Validate the IP address contained inside the request $this->validate($request, [ 'ip_address' => 'required|ip' ]); }

The $request->merge() method will allow you to add items to the form request, and then you can just make a simple validate request on the IP only.

Alternatively, you could move all this to it's own Request class and inject that into the method.

Answer can be found in the documentation for Proxy class: https://docs.oracle.com/javase/7/docs/api/java/lang/reflect/Proxy.html

An invocation of the hashCode, equals, or toString methods declared in java.lang.Object on a proxy instance will be encoded and dispatched to the invocation handler's invoke method in the same manner as interface method invocations are encoded and dispatched, as described above. The declaring class of the Method object passed to invoke will be java.lang.Object. Other public methods of a proxy instance inherited from java.lang.Object are not overridden by a proxy class, so invocations of those methods behave like they do for instances of java.lang.Object.

Also, I think it has something to do with the fact that the toString() method has a default definition:

public String toString() { return getClass().getName() + "@" + Integer.toHexString(hashCode()); }

While getClass() (and wait(), notify() etc.) are defined as:

public final native Class<?> getClass();

So, to differentiate between which methods will not be proxied you can look fo presence of final native in the method definition.

However I would still expect the compiler to have enough information to compile the above piece of code.

No it doesn't. Because you didn't gave the compiler enough information.

You are using a raw type Wrapper in your code, in which case, all the generic type information is not available to the compiler. So, the compiler sees ArrayList<Wrapper> as just ArrayList, and that is why when you iterate over it, you'll get back Object type values and not Wrapper type.

See JLS § 4.8 - Raw Types for more details:

The type of a constructor (§8.8), instance method (§8.4, §9.4), or non-static field (§8.3) M of a raw type C that is not inherited from its superclasses or superinterfaces is the raw type that corresponds to the erasure of its type in the generic declaration corresponding to C.

Also See:

What is a raw type and why shouldn't we use it?

Reto Koradi already mentioned copy semantics. Another thing to keep in mind is that OpenGL allows context sharing, i.e. some objects are shared between the OpenGL contexts and deleting in one context deletes it from all contexts. Objects transcending shared contexts are

textures
buffer objects that are bound using glBindBuffer
render buffers

among the objects not transcending shared contexts are

framebuffer objects
vertex array objects

31329158 1 Manipulating validated data in Colander SchemaNode

I have a set of Colander SchemaNodes used with Pyramid/Cornice in an API. For some querystring args, a range is passed (ie time=X-Y means a time range from X to Y where X and Y are integers representing epochs). I currently validate this with a RegEx() validator to ensure an epoch or epoch range is passed in:

class TimeOrRange(SchemaNode): schema_type = String location = "querystring" description = 'Time (or range) in epochs: ssssssssss(-ssssssssss)' validator = Regex("^[0-9]{10}\-{0,1}[0-9]{0,10}$")

I then use this in a MappingSchema which is then tied to my Cornice view with @view(schema=TimedThingGet):

class TimedThingGet(MappingSchema): time = TimeOrRange(missing=drop)

What I would like to do is update the return value in my TimeOrRange SchemaNode code so time in TimedThingGet is a tuple of time ranges. In other words, if time=X-Y is passed in to a TimedThingGet instance, then time=(x, y) is returned in the validated data. Similarly, if only X is passed in, then I want Y to be set to the epoch of now().

It looks like set_value() is the way to go, and here's where the problem get's some extra credit:

Does set_value get called before or after validation?
Does set_value have access to the validator such that a RegEx validator which creates regex groups could then be used to set my tuple: time=(validated.match.group[1], validated.match.group[2])?

First of all, for capabilities, if it's a fixed list of capabilities you're working with, you're probably better off with having a number of booleans on the roles table, e.g. can_create_projects, can_create_users, etc., which encode the abilities of each role.

Then your CanCan Ability class might have something like the following,

class Ability include CanCan::Ability def initialize(user) can(:create, Project) do |project| user.roles.any?(&:can_create_projects) end end end

It should be a tab with the content "Testing", but the tab is empty.

What you are seeing is not that the tab is empty, but instead no tab is selected. Since you removed all existing tabs, no remaining tab can keep the selection. So when the underlying collection is changed again to add another tab, that tab does not get selected automatically. If you click on the tab though to select it, the content is still there. You can actually see this by the way the tab header looks when it’s not selected.

Further note, that all your Tabs instances share the single TestText list you created in your MainWindow. So when you change the content in any tab, you are automatically changing the content in all tabs that exist, or will exist in the future, since all instances always get the same ObservableList instance passed.

Well, your migration obviously did not complete successfully, based on the traceback. So I would focus on figuring out why it failed, rather than working around things like the broken RAMCache which are likely a result of the migration not having run.

The traceback indicates that it broke while trying to abort the transaction...so you'll probably need to do some debugging to determine what caused it to try to abort, since that's not indicated in the logs you pasted.

How is it possible to do this?

If I do a normal

You're probably getting that error because you are calling the theme file directly

because you aren't incuding the header and footer of the page.

Easy Solve:

Make sure the page loads as wanted. If you dont want to include the header and all that junk, you can load a fragment with jQuery doing something like this:

 .load('wp-content/themes/theme/reloadhomeposts.php #postWrapper', function() { $(this).removeClass('loading') });

23793046 0 Pixelate images when hovering over parent div using javascript

Searching around for ways to do this, I found a couple good explanations out there, and ended up combining them. I had everything working fine when I was just doing the hover effect when mousing over the image itself, but when trying to make it work when hovering over the "profile" div seems to have caused some problems. Currently, it will sometimes also be pixelated when not over the div, so it remains somewhere between the mouseover and mouseout states.

HTML

In the HTML, I'm creating a filterable directory of people using isotope that contains a bunch of blocks like this:

<div class="item profile p-1 undergrad research"> <div class="profile-image"> <img src="img.jpg"> </div> <div class="profile-text"> <h1>Name</h1> <h2>Position</h2> <p> Email:email@gmail.com<br> Phone: 123.345.6567<br> Office: 2818 </p> </div> </div>

Javascript

I'm using javascript to handle the pixelation stuff right now, but to be honest I'm a lot more familiar and comfortable with Jquery, so this has been a struggle and learning experience. Below is the whole code, but I'll explain what I changed that started my issues.

Originally, "items" in setup was taking .profile-image objects, and I changed that to .profile objects so I could use the ".profile" div as the object with the mouseover event listener. At this point I introduced "block", which i switched the event listeners to from "element".

Caching large objects in NoSQL stores is generally not a good idea, because it is expensive in term of memory and network bandwidth. I don't think NoSQL solutions shine when it comes to storing large objects. Redis, memcached, and most other key/value stores are clearly not designed for this.

If you want to store large objects in NoSQL products, you need to cut them in small pieces, and store the pieces as independent objects. This is the approach retained by 10gen for gridfs (which is part of the standard MongoDB distribution):

See http://docs.mongodb.org/manual/applications/gridfs/

To store large objects, I would rather look at distributed filesystems such as:

These systems are scalable, highly available, and provide both file and object interfaces (you probably need an object interface). You can also refer to the following SO question to choose a distributed filesystem.

Best distributed filesystem for commodity linux storage farm

Up to you to implement a cache on top of these scalable storage solutions.

14252678 0 Backbone.js per attribute rendering (multiple small views vs multiple templates per view )

I have a model and a view. The view displays attributes of a model and allows the user to manipulate these attributes. The problem is that when an attribute is modified it re-renders the whole view which causes a lot of problems for me.

Example blur event on a text input saves the new input to an attribute and thus fires render. Which means that if the user clicked from that text input straight to a button on the same view that event will never fire as the first event that fires will be blur causing the whole view to re-render and thus losing the button click event.

I have two ideas:

Have a single view where every attribute is in a separate template. Then I bind to a particular attribute change event and in render I update only the html of the changed attribute. This seems like a hack, as there is a lot of work to force the view to update only the changed attribute. It will add a lot of unnecessary complexity to an already complex view.
Create a master view which consists of views, where each of them represents a model's attribute. This will create a lot of views, with nearly no functionality.

I seem to prefer the 2. option. What do you think? What are the best practices? Is there any better way to handle this?

You can store a reference to the previously opened paragraph and hide it before displaying a new one. This has the advantage of being quicker if you have lots of paragraphs.

// My function to open and close the p tag var para = null var evtDelegation = function(evt){ var target = evtUtility.getTarget(evt); if(target.nodeName.toLowerCase() === 'h1'){ if(para !== null) { para.style.display = 'none'; } para = evtUtility.nextSiblings(target); para.style.display = 'block'; }; }; evtUtility.addEvent(document, 'click', evtDelegation);

36652205 0 Take let variable out of temporal dead zone

See this code:

<script> let {foo} = null; // TypeError </script> <script> // Here I want to assign some some value to foo </script>

The first script attempts to let-declare foo via a destructuring assignment. However, null can't be destructured, so the assignment throws a TypeError.

The problem is that then the foo variable is declared but uninitialized, so if in the 2nd script I attempt to reference foo, it throws:

foo = 123; // ReferenceError: can't access lexical declaration `foo' before initialization

And let variables can't be redeclared:

let foo = 123; // SyntaxError: redeclaration of let foo

Is there any way to take it out of the TDZ, so that I can assign values and read them?

I doubt that's actually a hash. It looks like base64 to me, which is an encoding. It's a slight technicality, but encoding's can be reversed easily, hash's can't.

EDIT: Running it through a base64 decoder, it's binary data (if it is infact a base64 encoded string). I believe it is though, the '=' on the end is a giveaway, and the rest of the string conforms to base64 too.

Adding my solution as answer, per halfer's advice: Solved this one, because I was passing the content to Zend_Pdf as a string, i should have been using Zend_Pdf::parse($new_pdf);, as it very likely says in the manual. (oops)

Further; I solved pretty much ALL of my problems with digitally signing PDFs of various versions and form constituents by moving to TCPDF, as several of the articles here suggest. A similar caveat was met with TCPDF though, when using strings, ensure that you are using TCPDF's 'writeHTMLCell' instead of 'writeHTML'. And watch for PHPs 'magic_quotes', errant whitespace, encoding, and goblins.

According to K&R,

A.8.4 Enumeration

...

The identifiers in an enumerator list are declared as constants of type int, and may appear wherever constants are required. If no enumerations with = appear, then the values of the corresponding constants begin at 0 and increase by 1 as the declaration is read from left to right. An enumerator with = gives the associated identifier the value specified; subsequent identifiers continue the progression from the assigned value

So mes_foo=5, mes_bar=6 and mes_joe=7. You don't need to do anything at compile time to know these values. Their values are fixed.

32375282 0 Getting Null Pointer Excetion While Populating data into listview

Please go through the following code and help me out. The data from the url is getting parsed but I am unable to populate in to the list view.

public class HomeFragment extends Fragment { View rootView = null; private ListView myListView; private String[] strListView; private String[] categ; private TextView catName; private CustomAdapter myAdapter; private DownloadJson downloadJson; private int i; private AsyncTask task; private Thread thread; public HomeFragment() { } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setHasOptionsMenu(true); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { rootView = inflater.inflate(R.layout.fragment_home, container, false); myListView = (ListView) rootView.findViewById(R.id.listview); new DownloadJson().execute(); // Inflate the layout for this fragment return rootView; }

This is my customAdapter which extends base adapter:

public class CustomAdapter extends BaseAdapter { private Context context; public CustomAdapter(Context context) { this.context = context; } @Override public int getCount() { return strListView.length; } @Override public Object getItem(int i) { return strListView[i]; } @Override public long getItemId(int i) { return i; } @Override public View getView(int i, View convertview, ViewGroup viewGroup) { View row= null; if(convertview == null) { LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); row = inflater.inflate(R.layout.list_item, viewGroup, false); } else{ row= convertview; } catName=(TextView) row.findViewById(R.id.Category); catName.setText(categ[i]); return row; } public String[] getValues() { return strListView; } }

These are my Xml files:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="info.androidhive.materialdesign.activity.HomeFragment"> <ListView android:id="@+id/listview" android:layout_width="wrap_content" android:layout_height="wrap_content"> </ListView> </RelativeLayout>

This is other xml:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="10dp" android:paddingLeft="10dp" android:paddingRight="10dp"> <TextView android:id="@+id/Category" android:layout_width="50dp" android:layout_height="50dp" android:gravity="center_horizontal" android:textStyle="bold"/> </LinearLayout>

And this was the error that I am getting:

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object android.content.Context.getSystemService(java.lang.String)' on a null object reference at info.androidhive.materialdesign.activity.HomeFragment$CustomAdapter.getView(HomeFragment.java:248)

See the documentation of Math.log : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/log

For further help you should ask your math teacher or someone who knows about algorithms ;-P

maybe you should see the part: ((b*c-a*d)/(c*c)*(Math.log(Math.abs(c*Xp+d)))) Maye you want to have the braces done like (x/(z*y)) or ((x*y)/z).

10815126 0 How to make black background and red color for drawing?

I have been developing the application for drawing. I have following code for main activity:

@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); Display display = getWindow().getWindowManager().getDefaultDisplay(); mMainView = new MyView(this, display.getWidth(), display.getHeight()); setContentView(mMainView); mPaint = new Paint(); mPaint.setAntiAlias(true); mPaint.setDither(true); mPaint.setColor(0xFFFF0000); mPaint.setStyle(Paint.Style.STROKE); mPaint.setStrokeJoin(Paint.Join.ROUND); mPaint.setStrokeCap(Paint.Cap.ROUND); mPaint.setStrokeWidth(12); mEmboss = new EmbossMaskFilter(new float[] { 1, 1, 1 }, 0.4f, 6, 3.5f); mBlur = new BlurMaskFilter(8, BlurMaskFilter.Blur.NORMAL); }

And code for my custom view for drawing:

public class MyView extends View { private static final float TOUCH_TOLERANCE = 4; private static final float MINP = 0.25f; private static final float MAXP = 0.75f; private Bitmap mBitmap; private Canvas mCanvas; private Path mPath; private Paint mBitmapPaint; private float mX, mY; public MyView(Context context, int width, int height) { super(context); this.setDrawingCacheEnabled(true); mBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888); mCanvas = new Canvas(mBitmap); mPath = new Path(); mBitmapPaint = new Paint(Paint.DITHER_FLAG); } @Override protected void onSizeChanged(int w, int h, int oldw, int oldh) { super.onSizeChanged(w, h, oldw, oldh); } @Override protected void onDraw(Canvas canvas) { canvas.drawColor(0xFF000000); canvas.drawBitmap(mBitmap, 0, 0, mBitmapPaint); canvas.drawPath(mPath, mPaint); } public void clearView() { mBitmap.eraseColor(Color.TRANSPARENT); } public Bitmap getState() { return mBitmap; } private void touchStart(float x, float y) { mPath.reset(); mPath.moveTo(x, y); mX = x; mY = y; } private void touchMove(float x, float y) { float dx = Math.abs(x - mX); float dy = Math.abs(y - mY); if (dx >= TOUCH_TOLERANCE || dy >= TOUCH_TOLERANCE) { mPath.quadTo(mX, mY, (x + mX) / 2, (y + mY) / 2); mX = x; mY = y; } } private void touchUp() { mPath.lineTo(mX, mY); // commit the path to our offscreen mCanvas.drawPath(mPath, mPaint); // kill this so we don't double draw mPath.reset(); } @Override public boolean onTouchEvent(MotionEvent event) { float x = event.getX(); float y = event.getY(); switch (event.getAction()) { case MotionEvent.ACTION_DOWN: touchStart(x, y); invalidate(); break; case MotionEvent.ACTION_MOVE: touchMove(x, y); invalidate(); break; case MotionEvent.ACTION_UP: touchUp(); invalidate(); break; } return true; } }

So, because if I try to save resulted bitmap as jpeg file using bitmap compress then all is good, but if I try to save as png file I will get file with transparent background (white) and red picture. I need that I can save using JPEG/PNG with black background and red picture. Code for saving is good, don't worry. Thank you.

34956492 0 using pusher npm in reactnative app

Did install the module to the project with:

npm install pusher --save

As soon as I add to a react component following line of code

var Pusher = require('pusher');

the xcode project stops compiling with following stack trace:

What am I doing wrong? Is pusher npm only meant to work in react.js web apps? Can I not use pusher npm as is in ractnative app? I know, maybe naive questions, but I'm very new to reactnative and the whole JS, Node, npm business.

To overcome the "ERROR: query has no destination for result data" error you don't need dynamic SQL.

You can select into a variable directly:

select parentid into parent from account where childid = child_id;

But you can simplify your function by using a recursive CTE and a SQL function. That will perform a lot better especially with a large number of levels:

create or replace function build_mp(child_id text) returns text[] language sql as $$ with recursive all_levels (childid, parentid, level) as ( select childid, parentid, 1 from account where childid = child_id union all select c.childid, c.parentid, p.level + 1 from account c join all_levels p on p.parentid = c.childid ) select array_agg(childid order by level) from all_levels; $$;

This is called "hoisting" SlowVariabele out of the loop.

The compiler can do it only if it can prove that the value of SlowVariabele is the same every time, and that evaluating SlowVariabele has no side-effects.

So for example consider the following code (I assume for the sake of example that accessing through a pointer is "slow" for some reason):

void foo1(int *SlowVariabele, int *result) { for (int i = 0; i < *SlowVariabele; ++i) { --*result; } }

The compiler cannot (in general) hoist, because for all it knows it will be called with result == SlowVariabele, and so the value of *SlowVariabele is changing during the loop.

On the other hand:

void foo2(int *result) { int val = 12; int *SlowVariabele = &val; for (int i = 0; i < *SlowVariabele; ++i) { --*result; } }

Now at least in principle, the compiler can know that val never changes in the loop, and so it can hoist. Whether it actually does so is a matter of how aggressive the optimizer is and how good its analysis of the function is, but I'd expect any serious compiler to be capable of it.

Similarly, if foo1 was called with pointers that the compiler can determine (at the call site) are non-equal, and if the call is inlined, then the compiler could hoist. That's what restrict is for:

void foo3(int *restrict SlowVariabele, int *restrict result) { for (int i = 0; i < *SlowVariabele; ++i) { --*result; } }

restrict (introduced in C99) means "you must not call this function with result == SlowVariabele", and allows the compiler to hoist.

Similarly:

void foo4(int *SlowVariabele, float *result) { for (int i = 0; i < *SlowVariabele; ++i) { --*result; } }

The strict aliasing rules mean that SlowVariable and result must not refer to the same location (or the program has undefined behaviour anyway), and so again the compiler can hoist.

You can set a birthdate to a contact (through the Contacts app) with only a month/day. The year is then set to 1604, it's just not shown. If before you do your ABRecordSetValue(), you set the year to 1604, the birthdate will show as just "May 5" when viewing the contact in the Contacts app. It appears as though this is the way Apple specifies 'no year'. You will have to manually check the date later if you plan on showing it otherwise you will display the 1604 year.

It largely depends on your overall technology stack. If you're already set up with nHibernate and there's no external motivating factor (business reason, etc), then there's no true need to move over to EF4. However, if you're almost exclusively using the MS technology stack, then moving to EF4 will further that effort.

That said, Spring.NET and nHibernate have a great, mature history of interoperability, and it's tough to fix what isn't broken. I'm in the process of building up a Domain Model using POCOs with EF4 and Spring.NET and can attest there are a lot of learning opportunities and instances of "OK, how am I going to do THAT?". But it's certainly doable and while there aren't many resources out there specifically of using EF4 and Spring.NET, there is good guidance in the general realm of EF4 and DDD.

Dunno if that helped at all, but it's my two cents on the topic.

SPOOL is a SQLPlus command, so you can not use it in a PlSQL block dynamically.

One way could be creating at runtime a second script, dynamically built based on your query, and then run it to do the job. For example:

conn ... set serveroutput on set feedback off variable fullpath varchar2(20); variable filename varchar2(10); variable extension varchar2(5); variable sep varchar2(1); /* spool to a fixed file, that will contain your dynamic script */ spool d:\secondScript.sql begin select 'filename', 'd:\', 'txt', '|' into :filename, :fullpath, :extension, :sep from dual; /* write the second script */ dbms_output.put_line('set colsep ' || :sep); dbms_output.put_line('spool ' || :fullpath || :filename || '.' || :extension); dbms_output.put_line('select 1, 2, 3 from dual;'); dbms_output.put_line('spool off'); end; / spool off /* run the second script */ @d:\secondscript.sql

This gives:

SQL> sta C:\firstScript.sql Connected. set colsep | spool d:\filename.txt select 1, 2, 3 from dual; 1| 2| 3 ----------|----------|---------- 1| 2| 3

d:\filename.txt:

1487275 0 Programmatically switch the ID generator in NH mapping file

So I'm currently attempting to do a promotion of objects from one database to another in my app. Basically I want to allow the user to click a button and promote changes from staging to production, as it were.

To do this, I really want to keep the IDs the same in order to help with debugging. So for example if the object has an ID of 6 in the staging db, I want it to have that same ID on production. To do this, we turned off identity on our production db and just made those primary key columns with non-null integers.

In my staging mapping file, my IDs are mapped using the "identity" generator, but for production I want them to be "assigned". Is it possible to programmatically change this, perhaps using an interceptor or something similar?

Thanks in advance!

You are not referencing the $id variable, but rather a string text id which breaks the query statement. Add a dollar sign to reference the variable, and if it's anything but an integer, wrap it in single quotes, too.

$query = "UPDATE utilizatori SET username = '$username', {...}, ip = '$ip' where id= '$id' ";

<div id="menu"> <?php if (isset($secondary_menu)) { ?><?php print theme('links', $secondary_menu, array('class' => 'links', 'id' => 'subnavlist')); ?><?php } ?> <?php if (isset($main_menu)) { ?><?php print theme('links', $main_menu, array('class' => 'links', 'id' => 'navlist')) ?><?php } ?> </div>

For more information on how to convert a drupal 6 theme to drupal 7 I would recommend going through this tutorial:

https://drupal.org/node/254940#menus

public void run(){ try { //do something try{Thread.sleep(3000);}catch(Exception e){} //do something }catch(Exception e){} }

19117076 0 Animate control with respecting parents/container

I have a control that I move with help of animation from the bottom to the final position. My problem is now that I want to change the behaviour of the animation, so that it respects the outer container (DarkGray).

The orange Ractangle should only be visible on the white background and not on the darkgray Grid!

Code:

MainWindow.xaml:

<Grid Background="DarkGray"> <Grid Margin="50" Background="White"> <Rectangle x:Name="objectToMove" VerticalAlignment="Bottom" Fill="Orange" Height="50" Width="50"/> <Button Height="20" Width="40" Margin="20" Content="Move" Click="Button_Click" VerticalAlignment="Top"/> </Grid> </Grid>

MainWindow.xaml.cs:

private void Button_Click(object sender, RoutedEventArgs e) { var target = objectToMove; var heightOfControl = target.ActualHeight; var trans = new TranslateTransform(); target.RenderTransform = trans; var myAnimation = new DoubleAnimation(heightOfControl, 0, TimeSpan.FromMilliseconds(600)); trans.BeginAnimation(TranslateTransform.YProperty, myAnimation); }

You can try this XPath to get text node after <a> element :

nodeValue = hd.DocumentNode .SelectSingleNode("//div[@class='resum_card']/p/a/following-sibling::text()");

Note: simply use single slash (/) instead of double (//) to select element that is direct child of current element. It is better performance wise.

27127242 0 seekg, fail on large files

I have a very large (950GB) binary file in which I store 1billion of sequences of float points.

A small example of the type of file I have with sequences of length 3 could be:

-3.456 -2.981 1.244 2.453 1.234 0.11 3.45 13.452 1.245 -0.234 -1.983 -2.453

Now, I want to read a particular sequence (let's say the sequence with index=2, therefore the 3rd sequence in my file) so I use the following code:

#include <iostream> #include <fstream> #include <stdlib.h> using namespace std; int main (int argc, char** argv){ if(argc < 4){ cout << "usage: " << argv[0] << " <input_file> <length> <ts_index>" << endl; exit(EXIT_FAILURE); } ifstream in (argv[1], ios::binary); int length = atoi(argv[2]); int index = atoi(argv[3]); float* ts = new float [length]; in.clear(); **in.seekg(index*length*sizeof(float), in.beg);** if(in.bad()) cout << "Errore\n"; **// for(int i=0; i<index+1; i++){** in.read(reinterpret_cast<char*> (ts), sizeof(float)*length); **// }** for(int i=0; i<length; i++){ cout << ts[i] << " "; } cout << endl; in.close(); delete [] ts; return 0; }

The problem is that when I use seekg this read fails for some indexes and I get a wrong result. If I read the file in a sequential manner (without using seekg) and print out the wanted sequence instead, I always get the correct result.

At the beginning I thought about an overflow in seekg (since the number of bytes can be very big), but I saw seekg takes in input a streamoff type which is huge (billions of billions).

Two simple options would be to either provide your user with some dictionary where they can register type mappings, or alternatively just provide them with a container interface that provides all of the services you think you're likely to require and allow users to supply their own wrapped containers. Apologies if these don't quite fit your scenario, I primarily use Unity, so I don't know if Ninject, etc. do fancy things Unity doesn't.

Possibly not the most relevant answer to your original question but since I got redirected to this page while looking for a way to control the formatting of DateTime properties in the serialisation someone else might find it useful.

I found that by adding the following to your app.config/web.config instructs the .NET serialisation to format DateTime properties consistently:

 <system.xml.serialization> <dateTimeSerialization mode="Local" /> </system.xml.serialization>

If you're testing for a property to be in an array, you can use the Contains extension method on IEnumerable, which is probably preferable to building a string. Try this:

Before I got here i used the following code to remove those columns that had no values at all or some NA's.

 rem = NULL for(col.nr in 1:dim(E.3)[2]){ if(sum(is.na(E.3[, col.nr]) > 0 | all(is.na(E.3[,col.nr])))){ rem = c(rem, col.nr) } } E.4 <- E.3[, -rem]

Now I need to remove the "date" column but not based on its column name, rather based on the fact that it's a character string.

I've seen here (remove an entire column from a data.frame in R) already how to simply set it to NULL and other options but I want to use a different argument.

I do not know which packages and data I need to reproduce your example but you can use a sequence of daily dates, the merge function and the NA filler in the zoo package to create the daily data frame:

library(zoo) # Date range sd = as.Date("1970-01-01") ed = Sys.Date() # Create daily and monthly data frame daily.df = data.frame(date = seq(sd, ed, "days")) monthly.df = data.frame(date = seq(sd, ed, "months")) # Add some variable to the monthly data frame monthly.df$v = rnorm(nrow(monthly.df)) # Merge df = merge(daily.df, monthly.df, by = "date", all = TRUE) # Fill up NA's df = transform(df, v = na.locf(v))

This might not be the fastest way to obtain the data frame but it should work.

It's because you use http://underscorejs.org/#without, which creates a copy of the array instead of just removing the item. When you remove an item a new array will be linked to the scope, and the new array is not linked with array in the isolate scope.

To solve this problem you can use splice instead, which removes the item from the original array:

$scope.removeSkill = function() { $scope.profile.skills.splice(_.indexOf($scope.profile.skills, this.skill),1); };

...

$scope.removeItem = function() { $scope.list.splice(_.indexOf($scope.list, this.item),1); };

28616911 0 How to set an ImageView to match_parent and horizontally scale accordingly?

I have a RelativeLayout in a section of my activity that includes a button and an ImageView. The size of the RelativeLayout is ListPreferredItemHeight and what I would like to do is have the ImageView span from top to bottom of that layout and be scaled accordingly.

Currently, without implementing any scaling attributes, I have this image:

enter image description here

I achieve this with the following xml code:

<RelativeLayout android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1"> <Button android:id="@+id/newPrescription_Medication" android:gravity="center" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" android:layout_toLeftOf="@+id/newPrescription_AddMedication" android:layout_toStartOf="@id/newPrescription_AddMedication" android:text="@string/select_medication"/> <ImageView android:id="@+id/newPrescription_AddMedication" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_alignParentRight="true" android:layout_alignParentEnd="true" android:src="@drawable/add_icon"/> </RelativeLayout>

Now, to try and fill the space with the button, I added the following to the ImageView tag:

android:adjustViewBounds="true" android:scaleType="centerInside"

enter image description here

How can I get the entire image to appear, while maintaining its position on the right side of the layout and filling the rest with the button?

This error means that Rails.application isn't initialized. I didn't actually know that, I cheated.

So that then begs the question: how did you set up this application?

Perhaps this application doesn't contain a config/application.rb file that defines a class that inherits from Rails::Application and therefore is causing this problem. In my application here, I've got this one you could use as an example.

By submitting the form in HTML you basically tell the browser to generate a normal HTTP request, usually POST or GET, for an URL defined in tag with form fields attached according to the specified method either appended to the URL or included in the request data.

There is nothing really special or different from a "normal" HTTP request, in fact you can manually "submit a form" by appending form keys and values to the URL in your browser and navigating to it in case of GET method.

Summarizing:

1) Yes, you are right.

2) From what I've just read (never used REST personally) a REST application is implemented by a servlet mechanism and uses HTTP protocol, so it should be possible to write a REST application for processing HTML forms if the form points to this application's URL.

Technically the copy constructor gets invoked in the following cases:

explicit copy construction
call by value
return by value

The assignment operator is implemented to obliterate an exiting instance's old contents with new ones. As you showcase an example:

myClass newInstant; newInstant = oldInstant;//assignment operator

Keep in mind that they work differently. Copy-swap involves in the assignment operator.

Regarding your last question, modern compilers apply copy constructor elision to elide unnecessary copy constructor call.

I had this issue recently with another group of plugins recently. One wouldn't allow me to disable it because it dependeded on the other, but the other was disabled and wouldn't allow me to enable it because of the dependency.

All you have to do to fix this is go to your jenkins installation, and under the plugins directory look for the plugin_name.jpi file. For the disabled plugin, you should see a file called plugin_name.jpi.disabled. Just delete the disabled file and then you should be able to enable / disable the plugins through the UI.

Note: you can also manually disable plugins by creating a disabled plugin file using the naming convention above.

Thanks for the heads up about the bug report and fix. I feel the need to give an answer to this question though, just in case you haven't ditched PHP and Slim framework altogether. Hopefully, it will be of help to someone else.

My approach to this would be:

<?php use Slim\Http\Request; use Slim\Http\Response; class AuthenticationMiddleware { public function isAuthenticated($userid, $authorization) { //do data validation here return false; } public function createErrorResponse($code, $msg, Response $response) { return $response->withStatus($code) ->withHeader('Content-Type', 'application/json;charset=utf-8') ->withJson($msg); } public function __invoke(Request $request, Response $response, $next) { $userid = $request->getHeaderLine('userid'); $authorization = $request->getHeaderLine('Authorization'); if(!$this->isAuthenticated($userid, $authorization)) { $msg = 'You are unauthenticated. Please login again'; $code = 400; $this->createErrorResponse($code, $msg, $response); } else { $response = $next($request, $response); } return $response; } }

Let me just say this. I would abstract a few stuff here in this code so I don't end up repeating myself. I see you repeating:

public function createErrorResponse($code, $msg, Response $response) { return $response->withStatus($code) ->withHeader('Content-Type', 'application/json;charset=utf-8') ->withJson($msg); }

In all your middleware and perhaps, in your routes. Hope this sets someone on the right track.

The div with the class `.number. must be flexible, its content is variable.
The content in the .text div gets clipped based on the content in the number div (widths cannot be fixed as the content in the number div is dynamically generated)

You can use the ANSI colour codes. Here's an example program:

#include <stdio.h> int main(int argc, char *argv[]) { printf("%c[1;31mHello, world!\n", 27); // red printf("%c[1;32mHello, world!\n", 27); // green printf("%c[1;33mHello, world!\n", 27); // yellow printf("%c[1;34mHello, world!\n", 27); // blue return 0; }

The 27 is the escape character. You can use \e if you prefer.

There are lists of all the codes all over the web. Here is one.

The issue is the static variable item is initialized to 0 when the class loads. Once you change it by reading in the user inputted value, you don't allocate properly sized arrays for your static variables. You can fix this by doing so after reading in the value:

public static void addItem() { Console.WriteLine("\nAmount of items to add"); item = Convert.ToInt32(Console.ReadLine()); // initialize static vars to correct size, now that we have #items product = new string[item]; code = new string[item]; price = new string[item]; unit = new string[item]; Console.WriteLine("Insert the items."); for (int i = 0; i < item; i++) { Console.WriteLine("\nItem[" + i + "]: "); Console.Write("Product[" + i + "]: "); product[i] = Console.ReadLine(); Console.Write("Code[" + i + "]: "); code[i] = Console.ReadLine(); Console.Write("Price[" + i + "]: "); price[i] = Console.ReadLine(); Console.Write("Unit[" + i + "]: "); unit[i] = Console.ReadLine(); } }

also i was trying to send url of file saved on S3, so instead of that i need to read that file from url and then send it as attachment

 require "open-uri" def send_refer_pt_request(params, attachment) if attachment.present? mime_type = MIME::Types.type_for(attachment).first url_data = open(attachment).read() attachments["#{attachment.split('/').last}"] = { mime_type: mime_type, content: url_data } end mail( to: <some_email>, subject: "Refer Request", tag: "refer_request") end

First, you should not use find('list') since it returns key/value pairs, you want to use (e.g.):

$types = $this->Types->find()->select(['id','name','color'])->toArray();

Then in your view, you want to be able to store the color attributes, so e.g.:

// Convert your $types array to something we can send to `select` $options = array_map(function ($e) { return [ 'value' => $e->id, 'text' => $e->name, 'templateVars' => [ 'color' => $e->color ] ]; }, $types); // Use a custom template for the `option` element to store the color as a data- attribute $this->Form->templates([ 'option' => '<option value="{{value}}" data-color="{{color}}"{{attrs}}>{{text}}</option>' ]); // Create the select element echo $this->Form->select('type', $options, [ 'empty'=>'Types', 'class' => 'form-control', 'id' => 'types' ]);

See the cookbook if you don' t know what are additional template variables (templateVars ) - You need CakePHP 3.1+ to use templateVars.

You will get something like:

<select name="type" class="form-control form-control" id="types"> <option value="" data-color="">Types</option> <option value="1" data-color="ff0000">Red</option> <option value="2" data-color="0000ff">Blue</option> <option value="3" data-color="00ff00">Green</option> </select>

For the following, I am assuming you have an element with id="color-preview" in which you want to set the background color, e.g.:

<div id="color-preview"></div>

Here is what the javascript code would look like (with jQuery):

$('#types').on('change', function () { var opt = $(this).find(':selected'); var col = ''; if (opt.data('color')) { col = '#' + opt.data('color'); } $('#color-preview').css({background: col}); });

Without jQuery (modern browser only):

var previewDiv = document.getElementById('color-preview'); document.getElementById('types').addEventListener('change', function () { var opt = this.options[this.selectedIndex]; var col = ''; if (opt.dataset.color) { col = '#' + opt.dataset.color; } previewDiv.style.background = col; });

jQueryUI extends the animate class for this reason specifically. You can leave off the original parameter to append a new class to your object.

17396528 0 Warning: Attempt to dismiss from view controller while a presentation or dismiss is in progress

I almost broke my brain on this one

Here is the error: Trying to show status page at the login page 2013-06-30 20:47:53.422 MyProgram[489:907] Warning: Attempt to dismiss from view controller while a presentation or dismiss is in progress!

I have the following code in SCAppDelegate.m

- (void)showStatusViewController { MLStatusViewController* statusViewController = [[MLStatusViewController alloc] initWithNibName:@"MLStatusViewController" bundle:nil]; UIViewController *topViewCntrller = [self.navController topViewController]; [topViewCntrller presentModalViewController:statusViewController animated:NO]; }

Then I have another view controller where when a user saves data I want to move to another (status) view controller. I don't see how I can add another controller on top so my understanding is if I disband the current one and go back to SCAppDelegate method above that it should show that status page.

This is the code in that view controller that is trying to disband/show status view controller.enter code here

[self dismissViewControllerAnimated:YES completion:^{ SCAppDelegate* appDelegate = [UIApplication sharedApplication].delegate; [appDelegate showStatusViewController]; }];

I know this comes from the lack of understanding how view controllers work and I read the guide, but still can't seem to figure this out.

I am using Facebook API to login into the app, which is adding some complexity in how to manage view controllers.

Any ideas will be super welcome :D

Thank you!

How are you hosting your service?

If your service is hosted in IIS, it is possible that the application was recycled between the 2 calls. In this case the app domain is recreated and the static members loose their values.

I'm going to hazard a guess that your statement that the code is "slightly modified to work" means that this code:

newlistitem.Value = options[j][valuefield].ToString() + ((options[j]["pdprice"].ToString().Length > 0 ) ? "/" + options[j]["pdprice"].ToString() : "" );

actually looked like this:

newlistitem.Value = options[j][valuefield].ToString() + options[j]["pdprice"].ToString().Length > 0 ? "/" + options[j]["pdprice"].ToString() : "";

(note the missing parenthesis)

The reason that this code will produce this error is that due to operator precedence, what will get evaluated is this:

String a = options[j][valuefield].ToString(); Int32 b = options[j]["pdprice"].ToString().Length; String c = a + b; Boolean d = c > 0; String e = "/" + options[j]["pdprice"].ToString(); String f = ""; newlistitem.value = d ? e : f;

With this way of looking at it, a+b will produce a new string, since adding something to a string will convert that something to a string for concatenation. Basically, "xyz" + 3 gives "xyz3".

By adding the parenthesis, your "slight modification", you've essentially rewritten the code to do this:

String a = options[j][valuefield].ToString(); String b = options[j]["pdprice"].ToString().Length; Boolean c = b > 0; <-- this is different String d = "/" + options[j]["pdprice"].ToString(); String e = ""; String f = c ? d : e; String g = a + f; <-- and this newlistitem.value = g;

Notice the difference between d in the first code and c in the second code. You've moved the concatenation of the string out where it belongs, together with the other strings.

So your slight modification works since it is the correct way of doing it, if you want to keep those expressions.

The accepted answer is a much better alternative. My goal was to give you an explanation as to the reason of the exception.

27722636 0 node.js mongodb projection ignored when there is a criterion

I am writing a node.js application using express, mongodb, and monk.

When I do a find with criteria only or with projections only, I get the expected result, but when I do a find with both, the full documents are returned, i.e., the projection is not performed. My code looks like this:

var collection = db.get('myDB'); collection.find({field1: "value"},{field2: 1, _id: 0},function(e,docs) { ...do stuff with docs... });

It returns not just field2 but all fields of all the docs matching the criterion on field1. I can get field2 from this, but I don't like the inefficiency of it.

Is there a way to use both criteria and projections?

The Canvas element is essentially a drawing canvas that can be painted on programmatically; a sort of scriptable bitmap drawing tool for the web.

I suppose the "amazing" thing about it, apart from the fact that we can now all create web-based MS Paint clones with ease, is that you have a much richer, completely free-form area for creating complex graphics client-side and on-the-fly. You can draw pretty graphs, or do things with photos. Allegedly, you can also do animation!

Mozilla's Developer Center has a reasonable tutorial if you want to try it out.

You should take it as more of a symptom than part of the actual problem when you are stuck in system all the time.

Memory fragmentation and paging out is the usual suspect, but it could be a myriad of things.

In my experience performance problems are seldom something obvious like you are calling something specifically. Optimizing like commonly suggested is usually useless at a really low level. It catches things that amount to bugs that are correct but usually unintended like allocating something and deleting it over and over but for things like this you often need to have a deep understanding of everything happening to figure out exactly where the issue is (but like I said, surprisingly often it's memory management related if you are stuck in system calls a lot).

26850634 0 Applying multiple IF functions to every row

I need to apply the following IF functions to every row in columns J, L, and S so that the correct date value is printed in the corresponding cell in row T. For example, cell T2 will have a date printed in it based on the outcome of running these IF functions on J2, L2, and S2; cell T3 will have a date printed in it based on the outcome of running these IF functions on J3, L3, and S3; and so on. Here's what I have got:

Sub Test1() Set firstDate = Range("S2") If Range("J2") = "GS/CA/SL/GW" Then If Range("L2") = "1" Or "2" Or "3" Then Range("T2") = DateAdd("ww", 52, firstDate) End If If Range("L2") = "4" Or "5" Or "6" Then Range("T2") = DateAdd("ww", 104, firstDate) End If If Range("L2") = "7" Or "8" Or "9" Then Range("T2") = DateAdd("ww", 156, firstDate) End If End If End Sub

It works on one set of cells at a time if I just redefine all the ranges, but I thought there must be an easier way than pasting and editing the code ~3500 times for all the rows I have to run it on. Any help would be appreciated!

As an additional idea, the problem of GarethD's method is, that it requires more or an equal number of rows in the second table as in the first table.

So you can just do a cross join of the second table with the first one, and limit the results to the number of rows in the first table.

WITH PatientCTE AS ( SELECT PatientID ,pat_FirstName ,pat_LastName ,pat_StreetName ,pat_PostalCode ,pat_City ,pat_DateOfBirth ,rn = ROW_NUMBER() OVER(ORDER BY NEWID()) FROM Patients ) , SampleData AS ( SELECT TOP (SELECT COUNT(*) FROM PatientCTE ) GivenName ,SurName ,StreetAddress ,ZipCode ,City ,Birthday ,rn = ROW_NUMBER() OVER(ORDER BY NEWID()) FROM FakeNameGenerator CROSS JOIN PatientCTE ) UPDATE p SET p.pat_FirstName = fn.GivenName ,p.pat_LastName = fn.SurName ,p.pat_StreetName = fn.StreetAddress ,p.pat_PostalCode = fn.ZipCode ,p.pat_City = fn.City ,p.pat_DateOfBirth = fn.BirthDay FROM PatientCTE AS p INNER JOIN SampleData AS fn ON fn.rn = p.rn

This function could probably be improved upon. Tip of the hat to @thelatemail.

lm.3Trans = function(y, x1, x2, transformations = c(log,sqrt,pwer)){ pwer = function(x, p = 2) poly(x,p) res = lapply(transformations, function(f) lm(y ~ f(x1) + x2)) res }

This will output your models into a list to which you could then do something like:

lapply(lm.3Trans(y,x,x1), summary)

To get more detailed summaries

It might be worth expanding this function to take a formula, and perhaps another arguement to identify which predictor should be transformed. Please let me know if that is useful.

Two things makes this Class very useful:

Application class is instantiated before any other Activity.
It holds the Application Context

Context brings a host of resources for us: we can figure out some device properties, load some resources, initiate a SQLite database etc, etc.

All of this happens before any Activity loads, and all of this is globally available to the Activities.

Simple example of what I mean:

public class App extends Application{ private static Resources sResources; //--I want to load strings resources from anywhere-- public static String loadStringResource(int resID) { return sResources.getString(resID); } @Override public void onCreate() { super.onCreate(); sResources = getResources(); //---I want to load all preferences when my app starts--- PreferenceManager.setDefaultValues(this,R.xml.prefs,false); } }

I think I see what's going on here. It's actually impossible for the Fragment to be duplicated with only one view container.

I suspect that the items in your ListFragment are getting duplicated due to the call to populateList() in onActivityCreated().

BecauseonActivityCreated() is called every time you click the back button to return to ColorListFragment from SaturationListFragment, it is calling populateList() every time. See documentation here

In order to fix your issue, just move the call to populateList() to onCreate(), which is only called the first time the ListFragment is initialized:

public class ColorListFragment extends ListFragment { private List<ColorGD> mDrawableList = null; private ColorAdapter mAdapter = null; //add the onCreate() override @Override public void onCreate(Bundle savedInstance){ super.onCreate(savedInstance); populateList(); //add this here } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_color_list, container, false); } @Override public void onActivityCreated(Bundle savedInstanceState){ super.onActivityCreated(savedInstanceState); //populateList(); //remove this //..................

To go back to original app you can use telprompt:// instead of tel:// - The tell prompt will prompt the user first, but when the call is finished it will go back to your app:

A generic approach:

:%s/\(<string name="\)\(\u\)\([^" ]\+\) \([^" ]\+\)/\1\l\2\e\3_\4/

This replaces every string @name that

starts with an upper case character (\u) and
consists of two space-separated words ($[^" ]\+$ $[^" ]\+$) and
replaces it with the corresponding lower-case character (\l\2\e).
It also replaces the space with an underscore.

To make everything in @name lower-case, this could be simplified:

:%s/\(<string name="\)\([^" ]\+\) \([^" ]\+\)/\1\l\2_\3_\e/

To get rid of multiple spaces, do two steps. First, make the attribute value lower-case:

:%s/\(<string name="\)\([^"]\+\)/\1\l\2\e/

then, replace every space in the attribute value with an underscore

:%s/\(<string name="[^"]*\)\@<= /_/g

Note that the \@<= is vim's way of expressing a positive look-behind assertion.

20572875 0 DataGridView CellContentClick event missed if SelectionChanged event handled?

I'm using C++/CLI .NET 4.5 on Win7. I develop a control with a DataGridView. The cells are not editable by the user neither it is possible to add rows manually.

I need to catch/handle the SelectionChanged event, so I added a handler for it. I also need to catch/handle the CellContentClick event, so I added too the handler for it. If I click on the content of a cell, of course the selection is changed but I would like to catch the event for the click too. The handler for CellContentClick is never called.

If I remove the SelectionChanged handler, the CellContentClick is catched as wanted.
If I put a return as the first line of my SelectionChanged handler, the CellContentClick is never catched neither.

It looks like if the handler for the Selection forbids the event for the click to be fired????

Any idea? Let me know if you need more info about the settings of my DataGridView.

Thanks!

I'm still not sure I understand the question. However, I do know for sure that the C# code you posted won't show anything, because the Rectangle object's width and height are both their default value of 0. An empty rectangle won't draw anything.

And then I declare MainWindow like this:

public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); Rectangle rect = new Rectangle { VerticalAlignment = VerticalAlignment.Center, HorizontalAlignment = HorizontalAlignment.Center, Fill = (Brush)FindResource("Alcanc"), Width = 200, Height = 150 }; canvas1.Children.Add(rect); } }

Your graphic is drawn correctly. Well, it's drawn…I don't actually know what size you wanted it. But the key is, you need to specify a size.

22097029 0 Nested Dictionary in R

I'm more used to a python environment. Is there a way to produce a dictionary/list that is fully dynamic. I.e. that I could create flexible data structures say that relate to a particular number such as

[1:["var_a":6, "var_b":3],2:[..]]

Where I will not know how may elements in each list. Is there a way to do this?

I figured I'd elaborate on my comment. I'd just have some bitwise fun.

char string[] = "123456" byte1 = ((unsigned char)string[0] << 4) | (unsigned char)string[1]; byte2 = ((unsigned char)string[2] << 4) | (unsigned char)string[3]; byte3 = ((unsigned char)string[4] << 4) | (unsigned char)string[5];

I was battling this for a few hours as well and came up with a solution. In my project i am using angular to control the actual view switching. so what i did was to define two separate route groups in L4, one that returns actual pages directly from laravel's routing system and another that returns HTML fragments for angulars routing system.

Here is an example of my routing

//Laravel pages and API routes Route::get('/', function() { return View::make('hello'); }); Route::get('/register',function(){ return View::make('registration'); }); //Angular SPA routes(HTML fragments for angulars routing system) Route::get('/getstarted', function(){ return View::make('getStarted'); }); Route::get('/terms',function(){ return View::make('terms'); });

So in this scenario, laravel sends your home page when you call "/", and the ng-view asks for "/getstarted" by ajax which returns your html fragment. Hope this helps :)

I know for sure that the C++ version supports merging two channels, so you can use it. Have you tried passing two input images and NULL for the rest?

7488838 0 Gradient Backgrounds in internet explorer version <=8

I need to have gradient backgrounds on my website for internet explorer. I know there is some kind of proprietry way of doing this:

filter: progid:DXImageTransform.Microsoft.gradient(startColorStr='#20799d', EndColorStr='#5cb9df');

But this doesn't grok with border-radius (supported by IE8, at least), which my site uses all over the place.

How should I solve this? (Other than just not having gradient backgrounds on old versions of IE, I mean.)

28223574 0 Try to move UIImageView in screen with touchesMoved

I try to move 2 UIImageView.

Only one picture is supposed to move when I drag.

What I trying to accomplish is move UIImageView when I touch and drag the UIImageView.

This Is my viewDidLoad :

-(void)viewDidLoad { [super viewDidLoad]; myImageView = [[UIImageView alloc]initWithFrame:CGRectMake(100, 100, 200, 100)]; [myImageView setImage:[UIImage imageNamed:@"image1.png"]]; [self.view addSubview:myImageView]; myImageView1 = [[UIImageView alloc]initWithFrame:CGRectMake(100, 200, 200,100)]; [myImageView1 setImage:[UIImage imageNamed:@"image2"]]; [self.view addSubview:myImageView1]; }

This Is my touchesMoved method :

 - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { // get touch event UITouch *touch = [[event allTouches] anyObject]; CGPoint touchLocation = [touch locationInView:self.view]; for (UIImageView *image in [self.view subviews]) { if ([touch view] == image) { // move the image view image.center = touchLocation; } } }

In this line I don't get the images view

for (UIImageView *image in [self.view subviews])

It is possible to get the current touched UIIamgeView ?

You might also consider using Packer to create VirtualBox images for developers to use.

Rather than sharing the Vagrantfile which developers each use to build and run their VM, you would have a packer template (json) which is used to create a VM image. Developers download or copy the image and run it locally, directly in VB, without having to build it themselves.

Many of the publicly shared Vagrant base boxes are created with Packer.

I used the (penultimate) code in Robert McKee's solution, however, had to adapt it to get it to compile and display correctly in the view:

public ActionResult Create() { ViewBag.AllSystems = new MultiSelectList(db.dbSystem.Select(x=>new { Name=x.systemName, Value=x.systemId }),"Value","Name"); return View(); }

etc....

Create a List<TextBox> for each group:

 List<TextBox> list01 = new List<TextBox>() { tbPlay0, tbPlay1, ....}; List<TextBox> list02 = new List<TextBox>() { ..., ... , ....}; // .. }

And pass such a group to the function:

private void convertBasetoDrawn(List<TextBox> list, string numBase, string reference) { string[] texts = new string[8] { "000", "500", "050", "005", "550", "505", "055", "555" }; for (int t = 0; t < list.Count; t++) list[t].Text = texts[t]; list[0].ForeColor = Color.Red; list[7].ForeColor = Color.Red; }

Assuming the texts will always look like that. If they depend on, maybe numbase you can construct them dynamically as well, as long as you know the rules.. Maybe even a simple replacement will do the job?

You didn't use reference, btw..

Now, I'm just guessig here, but maybe this is the pattern for your texts..:

 string[] texts = new string[8] { "nnn", "dnn", "ndn", "nnd", "ddn", "dnd", "ndd", "ddd" }; for (int s = 0; s < texts.Length; s++) texts[s] = texts[s].Replace("d", numBase).Replace("n", reference);

Now you can call it like this:

convertBasetoDrawn(list01, "0","5");

Update: For the rules as I understand them now you could do:

string newText = ""; for (int s = 0; s < texts.Length; s++) { newText = ""; for (int i = 0; i < 3; i++) { if (texts[s][i] == 'n') newText += numBase[i]; else newText += (Convert.ToByte(numBase[i].ToString()) + Convert.ToByte(reference[0].ToString()) ).ToString("0"); } texts[s] = newText; }

and call it like this:

 convertBasetoDrawn(list01, "001", "5");

 convertBasetoDrawn(list02, "000", "1");

Note: no carry over here.. You'd have to define rules for that and code it yourself..
