How to update a large network of computers | st3fan: Some other thoughts:You mention data changes. So what about sending just the changes?What is the real problem? That it takes a lot of time? Or that it requires bandwidth?If downloads are slow, are your central servers overloaded?
What about putting the data on a CDN or Amazon S3? |
How to update a large network of computers | bayareaguy: A friend of mine told me this was a Google interview question. Anyways, I'd recommend taking a look at this:The Frisbee server uses a custom multicast protocol to distribute highly-compressed disk images to consenting clients. The Frisbee client is a multi-threaded marvel that receives, decompresses, and smacks data down on your hard drive, really, really fast. Frisbee can be used to install complete disk images or single partition images.- http://www.cs.utah.edu/flux/papers/frisbee-usenix03- http://www.emulab.net/software.php3 |
What Mouse Do You Use/Suggest? | tortilla: I'm an Apple fanboy, but I use this MS Wireless Laser Mouse 8000 with my Macbook Pro:http://www.amazon.com/Microsoft-Wireless-Laser-Mouse-8000/dp...I like it because I can switch to my right and left hand (I'm right handed). I used to get the sore finger and shoulders, so I switch sides often (every hour).The Bluetooth works without using the USB dongle but it's a bit flaky connecting sometimes. So I use the dongle now and I rarely have any connection problems or lagging.The rechargeable cradle works great and stays out of the way.Since I'm on OSX, I have to use SteerMouse to be able to customize all the extra buttons.

What Mouse Do You Use/Suggest? | brianloveswords: I actually try very hard to do everything with the keyboard. I'm an emacs zombie, though I'm sure the vim-o-nauts would agree: mousing is just really inefficient.BUT! It depends on what you do. Occasionally I have to break out the graphic design “skills” and for that, I have my Mighty Mouse. I don't know that I would recommend it, it's pricey, some people like having a tactile right click (me, I just disable the shit because it's a fucking farce on the mighty mouse anyway, getting it to work reliably is impossible and I have no problem with holding down an extra key for context menus). It depends on what you plan on mousing around on. My advice is to just keep getting the cheap $7 Logitech opticals and try more keyboard, less mouse. |
What Mouse Do You Use/Suggest? | jonny_noog: For my main desktop PC, I have for some time now had a Logitech G5, which I love. Coupled with my fUnc Surface 1030 mouse pad, it's awesome. Super light buttons and super smooth movement.I also have a Logitech G15 keyboard to go with, which is equally as awesome, mainly due to the feel of the keys, they too are very light and easy to use.All these products were originally bought by me for gaming reasons, but I have not had time to game for a very long while now, and have found that these products, while billed as gaming centric (which they are), are also excellent for general purpose use. |
What Mouse Do You Use/Suggest? | ivank: I use both the new G5 and the G9, alternating when I get tired of one or the other. However, all the new Logitech mice have inferior rigid cords (non-plastic), and it's fairly hard to middle click on either mouse. |
What Mouse Do You Use/Suggest? | Zak: IBM Trackpoint. I'd use a Trackpoint keyboard with a desktop if I regularly used a desktop. |
What Mouse Do You Use/Suggest? | wenbert: I always prefer those wired optical mice. They light and very responsive. I never liked those wireless ones. SO heavy :-( |
What Mouse Do You Use/Suggest? | bjclark: Call me crazy but I like my bluetooth mighty mouse. |
What Mouse Do You Use/Suggest? | xlnt: razer diamondback mouse. on mac, the razer proclick mac drivers work for it.it's designed for gamers. i like the mousing accuracy. i used to have a cheap mouse. one can tell the difference; this is much nicer. |
What Mouse Do You Use/Suggest? | s_tec: My main computer three pointing devices, a mouse, a trackball, and a tablet. If my hand gets sore from using one device, I just switch to another one. This works pretty well, since all three devices need different hand positions and muscle motions. |
What Mouse Do You Use/Suggest? | wmeredith: I've used all three of the Logitech Revolution mice and I recommend them to anyone I meet who uses a computer. Simply put, they are badass. |
What Mouse Do You Use/Suggest? | silencio: I absolutely love my logitech MX Revolution, except it's for right handed mousers (I like using both). I use a razer copperhead for gaming.To be honest, I prefer my tablet or the touchpad on my laptop. Feels more natural and comfortable. |
What Mouse Do You Use/Suggest? | ihartley: I have a logitech vx revolution and I love it. The freespinning mouse wheel is pretty awesome, and it has a few configurable buttons. The logitech control center on OS X sucks really hard, though. I recommend SteerMouse to solve that problem. |
managing subdomains cookbook | senthil_rajasek: Are you asking how http://www.morbidkk.com points to http://morbidkk.weebly.com ?There are a couple of ways you can achieve this,I use CNAMEs, this would be done by someone who controls the source domain's DNS, morbidkk.com in the above case.The other way is to create a direct DNS A record which is not so flexible and probably not possible in this specific scenario since we are talking sub-domains, which are typically created as vhosts.I actually don't understand your travelogue websites question?? Can you please elaborate? |
managing subdomains cookbook | samt: have not run not such a site myself, so take this with a grain of salt. I assume that most use a database-backed DNS server like MyDNS, so adding/removing/etc subdomains is a simple db call. |
What Mouse Do You Use/Suggest? | timcederman: My 3M ergonomic mouse takes away 90% of my RSI pain. |
What Mouse Do You Use/Suggest? | elsewhen: i couldnt be happier with the logitech v470 laser bluetooth mouse. if you have a laptop with built in bluetooth, this little mouse is fantastic. excellent mouse features (back, forward, scroll, and middle click) and the batteries last for weeks even with heavy usage. it takes AA batteries, so you can just use rechargeables. |
What Mouse Do You Use/Suggest? | apu: I really love the Microsoft Intellimouse Explorer: http://www.newegg.com/Product/Product.aspx?Item=N82E16826105...It's a 5 button corded optical mouse. Some people don't like the symmetric extra buttons, but they're really awesome for web-browsing (forward and back), and in other applications too. It has great accuracy and the mouse wheel 'clicks' when scrolling (so you know how many increments you've scrolled).Your tastes may vary. |
What Mouse Do You Use/Suggest? | hs: How about trying to repair your mouse first?Just open it. Most of the time (microsoft wheel mouse in my case) the prism lens is not aligned to the LED. Securing these with ducktape solved the problemBut really, use keyboard more and just ditch the mouse (or use less) so that u don't worry about it -- the biggest advantage being able to survive in environment where mouse is unavailable (say dead batteries while using wireless mouse) |
managing subdomains cookbook | johns: Wildcard DNS entry. Create an entry for *.example.com that points to your service and let the code figure it out. |
What Mouse Do You Use/Suggest? | gizmo: Laser is a must. It's inexpensive and is that much more reliable. Less frustration => less wrist pain.I use a G5.(If the tendon of your index finger is an issue RSI is on the way. This might be one of those cure the problem not the symptom situations.) |
managing subdomains cookbook | kitt: Pointer: google for subdomain rewriteIf you are using apache, and mod_rewrite, you can set up rewrite rules for subdomains.http://www.webmasterworld.com/forum92/4640.htm suggests rewrite rules to redirect a subdomain to a page/app on the main domain.Then, use a domain wild card to point everything to your main www.example.com host (create an A record (HOST) to point * to your IP address).Now, all example.com subdomains (hosts) will go to the A record IP address, which will be redirected to the program/pages/urls you expect.Next, have the customer modify their DNS to point to your IP address. If you want, you can do the request yourself to their current ISP, to update the domain's DNS, if they're keeping their email with the ISP. If they don't, and you're controlling their email, too, go with Google's hosted email.Now, this unknown domain is coming to your IP address. If you're using apache, set up the domain to go to the redirected domain. Easy way to do that is to set up a server alias, or have a virtual host that answers for everything:<VirtualHost *:80>
</VirtualHost>One way to do it, at least. |
What Mouse Do You Use/Suggest? | ra: Kingston Expert Mouse :- The sturdiest, healthiest most hacker friendly, RSI defending pointing device ever built.Worth their weight in gold (and they're quite heavy). |
What Mouse Do You Use/Suggest? | patrocles: when life gives you lemons, make lemonade ;)http://www.nongnu.org/ratpoison/ |
managing subdomains cookbook | natch: Your examples lend themselves to confusing answers, so I am changing the examples to use my own examples, which are of course totally clear and correct.Here's how the record in your zone file should look:foo IN CNAME lalala.bigpipe.com.The above (from foo all the way to .com.) should all be on one line. Note the . at the end is required.Now let's say this is the zone file on your web site, googoogaga.com. Now after this record takes effect, people can point to:http://foo.googoogaga.com/and they will get files from lalala.bigpipe.com, but their browser address bar will continue to show them foo.googoogaga.com. Nice, huh?You do not need to have access to the zone file on bigpipe.com; you only need to have access to put your content files you are serving onto lalala.bigpipe.com. Well, that is, unless you are using their content files. |
What Mouse Do You Use/Suggest? | MaysonL: Contour Perfit Optical Mouse (5 sizes righty, 4 lefty) three finger buttons, thumb-op scrollwheel + 2 thumb-op buttons. |
What Mouse Do You Use/Suggest? | edu: I switched to a trackball a couple of months ago. I own the Logitech Cordless TrackMan Wheel: http://www.logitech.com/index.cfm/mice_pointers/trackballs/d...It's a pretty awesome piece of hardware, big and very comfortable and with a nice touch. It uses an optical sensor so almost no cleaning is needed. Being cordless, the battery is not a problem as you're not supposed to move it around. |
How to update a large network of computers | bayareaguy: Here's another useful tool I just remembered.http://saf.bio.caltech.edu/nettee.html |
What Mouse Do You Use/Suggest? | arthurk: MX510 + Steelpad QcK |
What Mouse Do You Use/Suggest? | mhb: Is there a way to keep crud from accumulating on the low-friction pads on the bottom of my mouse? I thought that getting a Wowpad would take care of this, but it hasn't. Maybe the Surface 1030 that was mentioned solves this? |
What Mouse Do You Use/Suggest? | cpr: I love the "IBM USB Optical Scroll Travel Wheel Mouse" (search ebay with those terms to see what I mean). $1-2 each (I buy them by the dozen and spread them around liberally to friends and family; when they wear out (scroll wheel gets sticky or clunky) I just throw them out like a used-up pencil).Wonderful, small, responsive mouse with smooth scrolling. Works on any machine. (I use them with Macs as I'm a fanboi.) |
Recommendation for a good UI/UX expert? | alaskamiller: Should leave your email or contact info.Also, good UI/UX experts would already be busy with ongoing projects, your solicitation barely registers anything on an excitement scale. Should divulge a bit more info about your project, or industry, or what you want to do. |
Recommendation for a good UI/UX expert? | swombat: I hear the guy who does Apple's products is pretty good. |
Recommendation for a good UI/UX expert? | nextmoveone: Hey man I need to find a good one too. Too bad Tony Wright isnt for hire! |
Recommendation for a good UI/UX expert? | boucher: The best way to find a designer is find something you personally think is beautiful and well designed (or, if you think you have no taste, substitute your opinion for someone's you trust).Contact those people and try to convince them to work with you. Be prepared to spend a lot (which is going to be worth it if they're good). |
Recommendation for a good UI/UX expert? | guy_davis: Kaaren Schulz at Practical Usability (http://www.practicalusability.com/)Disclaimer: She's my cousin. :) |
Recommendation for a good UI/UX expert? | tptacek: I'd say Blue Flavor --- http://www.blueflavor.com --- they wrote Blueprint. I liked them a lot; excellent consultants. They may be out of your price range though. For the shops that you've heard of, for projects that include IA and UX in addition to pushing pixels, a small project falls in the 10-20 range.It does not sound like you want UX --- it sounds like you want a designer. If you just want to look nice, that's a $1500-$4000 project. My advice, based on our experience: post to Craigslist and compare portfolios. |
Recommendation for a good UI/UX expert? | luxstyle: Are you looking for a designer or a developer? UI folks like myself tend to come in 2 flavors. One is skilled at the wireframes, architecture and look and feel and can do pretty mockups and prototypes. The other is a programmer whom is familiar with the latest AJAX, JSPs etc and implements the design created by the former person.Also if the company is important to you as it should be you might want to hire someone familiar with branding to do your branding. Having a UI person do your branding is like having a programmer do your UI. They might know a bit about it but are definitely not the expert.Lastly, if you're looking for someone with recommendations but don't know anyone personally try linkedin.com. Check out some profiles, look at their recommendations and check out their website. You can see my profile as a starting point.,Jose Benavides |
Recommendation for a good UI/UX expert? | luchandy: Amy Hoy. She's amazing. She made twistori and Color Wars among other things. She's spoken at lots of conferences, so you can see her thoughts about UI right out in the open via her slides. Aside from knowing UX/UI, she seems to be an accomplished hands-on Ruby programmer, Javascript programmer, and graphic designer. http://www.slash7.com |
Recommendation for a good UI/UX expert? | izak30: I have a guy.He did the UX for our CMS, and has just quit his day job to do Freelancing full time (and work for Servee)Check out http://demo.servee.com for some UX work and
http://kkellydesign.com for general Design(also highlandpr.com/portfolio for branding work) |
Recommendation for a good UI/UX expert? | boredguy8: "web-based research aggregation tool"I personally know of at least two other in-the-works tools like this. I'm interested to see what the competitive space looks like for this market in the next 6-18 months. |
What Mouse Do You Use/Suggest? | jacobroufa: I highly recommend Logitech's VX Nano. I've had mine for almost 6 months now still using the original batteries, and I use it every day! It's small which I thought would be a pain at first (remember Apple's infamous "hockey-puck" mouse?), but it really feels natural in my hand. Also, it is precise on any surface I use it on, using the laser sensor. I really like the dual scroll wheel (clicky until you press down and then it freesrolls through any doc in 2 seconds) and the forward/back buttons. Its receiver is so tiny I just keep it plugged into my laptop and never worry about it. I could go on and on and on, but you get the point. |
What criteria do you use to {up,down}mod submissions? | noodle: i upmod sparsely. there's only 3 reasons i'll upmod:1) a new Ask YC/HN type thread that pertains to my interests. i want to see more experienced people respond to it, so i'll upmod it.2) a thread that has an interesting discussion in which i want to see more responses. i'll upmod it to get more eyes and answers.3) a submission or discussion i want to save for later reference/use. |

How many of you willing to give gmail/yahoo info to expand the network | iamdave: http://www.codinghorror.com/blog/archives/001128.htmlI wouldn't.editIt's worth noting to answer one of your questions: I don't follow my friends around to every new site that pops up. Primarily because only 10% of my friends are technically savvy enough to the point where I would actually use the word "Twitter" around them. I've found this is becoming increasingly more and more the case, we're establishing connections with like minded people online, and isolating ourselves to a certain extent when it comes to who among our friends knows their two cents about social content.That said, if I create an account on a site "just to test it out", I'll probably use my dummy email account in the first place partially out of habit, and partially to gather any extraneous crap that may get dumped in the inbox anyway. |
How many of you willing to give gmail/yahoo info to expand the network | michael_dorfman: I'd never use a site that asked me for my gmail (or any other) username/password.I'm not the only one who feels this way. Take a look at this, for a start: http://www.codinghorror.com/blog/archives/001128.htmlIf your social networking idea depends on this, start again. |
How many of you willing to give gmail/yahoo info to expand the network | colinplamondon: Most people don't care, the privacy implications are only worried about by people who know enough to worry about the privacy implications.Despite the Facebook Beacon blowup in the blog echo chamber, very few users cared:http://www.sawickipedia.com/blog/2007/12/05/facebook-bites-t...So, sure! People who read CodingHorror are concerned about the security issues... but how many of your users even know what the hell CodingHorror is?If your social network is focused on people who might have heard of CodingHorror, you might want to have second thoughts. If not, keep it secure and be careful about your implementation. Personally, if I trust a site then I'll use the address book import if provided.EDIT: Like mentioned above, definitely use Google's actual tool to do the import:http://code.google.com/apis/contacts/ |
How many of you willing to give gmail/yahoo info to expand the network | IsaacSchlueter: OpenID: If they have a yahoo account, the user just has to remember "yahoo.com" and if you're supporting OpenID 2.0, it'll work. If they have almost any kind of blog or social networking profile these days, it's also an OpenID.Users remember their OpenIDs. Use the discovery mechanisms built into the spec to do the hard part for them.Check out the RESTful apis being built as part of the OpenSocial specification. If they can tell you what network they're a part of that supports OpenSocial (Google, MySpace, hi5, Plaxo, and soon, Yahoo) then you'll be able to kick off an OAuth process that ends in them giving you permission to fetch their friendlist.But their email username and password? Don't ever do it.We're past that stage now. It's no longer state of the art, and it's dangerous enough that it ought to be considered harmful by all responsible adults. |
How many of you willing to give gmail/yahoo info to expand the network | babul: This may be helpful http://news.ycombinator.com/item?id=209870 |
How many of you willing to give gmail/yahoo info to expand the network | elad: Personally, I never ever give my email credentials out. I totally agree with Jeff Atwood on that.However, while you're at it, why not ask people for their facebooks/myspace credentials? You'll find many more "friends" there than in my email contacts, plus facebook is far less sensitive privacy-wise. If someone got hold of my credentials, the maximum they could do is deface my profile and send some stupid messages to friends. If they got hold of my gmail account, they could access almost every other account that I have through "forgot your password" links...Not that I'd actually give you my facebook credentials though :) |
How many of you willing to give gmail/yahoo info to expand the network | xlnt: Don't ask for people's passwords. Ugh. Just because other sites are acting badly doesn't mean you should too.Those sites that want your passwords have not figured out a decent solution to the problem. That's an opportunity. Do something better. |
How many of you willing to give gmail/yahoo info to expand the network | PieSquared: I think OpenID may be a good choice, especially as more sites begin to support it. Take a look at ClickPass, it seems promising, though I suppose you should offer a normal sign up too. |
How many of you willing to give gmail/yahoo info to expand the network | cmars232: Won't use it. |
How would you implement a small-scale EBay? | olefoo: Implement some sort of secured cryptographic identity for members that is tied to a phone number and a personal presence at a given place and time (stop by any $foo to use our automated signup kiosk and receive your free picture ID membership card) this would vastly reduce opportunities for fraud. |
How would you implement a small-scale EBay? | babul: For a start I would actually try and do something different from eBay initially just to offer USP/differentiation.However, assuming you want to create an eBay for use in your own site/society/community and competing with eBay is a non-issue, I would do it in the tools that allow building as easily and quickly as possible.I would use python/django because of simplicity in code style and they are good opensource frameworks for building web apps that incorporate many good paradigms. Others may prefer what is in thier skillset e.g. RoR/.NET/PHP, but that is preference... the auctomatic guys started building in common lisp.My approach would be KISS, working on the core essence i.e. an auctioning engine, and building iteratively there upon. I would also initially start by looking at what is broken in eBay and what people generally complain about and try to incorporate the learning into my roadmap but still focusing on the core competencies first. |
I want to add SMS to my service, tips/help/advice? | jonknee: Unless you're huge you aren't going to connect directly in with the operators. There are too many and the implementation is hell. You connect into a middleman who has direct connections to all the majors.Search for premium SMS providers. There are quite a few. It's probably not going to be cheap, especially if you want a dedicated short code (they rake you over the coals for that). m-bill.net is one that came up for me and I've heard of them in the past. They have agreements in place internationally, which can be a really good thing. But they don't list prices, which can be a bad sign.Realistically you're probably looking at $1000 a month minimum. And giving up about half the revenue (I think a lot goes to the carrier, but you can't really find out the exact percentage because the providers work off volume and what not). |
I want to add SMS to my service, tips/help/advice? | gizmo: It's called reverse billing. Lots of information out there, and a lot of providers. Don't use SMS as your primary source of revenue. Use reverse-billing just for a "fun" feature and hope to break even on it. |
How would you implement a small-scale EBay? | ericb: I'd start by looking for an open source project that does what I need and has a permissive license, then modify that.If I was starting from scratch, I'd probably use rails, and the activescaffold plugin. |
I want to add SMS to my service, tips/help/advice? | ruslan: As for simple sending/receiving SMS messages, we at gtalk2voip.com use Clickatell's SMS service, which is very flexible, offers good technical support and providers a number of APIs including SMTP, SMPP and HTTP (we use SMTP). Among their cons: their rates are quite high unless you pre-pay for 1M messages a month and they don't want to provide you with a complete list of rates associated to mobile phone (DEF) prefixes, so reselling SMSes is close to impossible, cause you have no means to know how to account your own users in real time :-(.As for selling content over SMS, as far as I know there's no way for a small startup company to get into revenue sharing deals with mobile carriers, besides there are a lot many of them. Yet, there are some companies that provide paid content distribution service, which you can use to resell your mobile service, software or other content you have right for (some junk like ring-tones, pron, etc). They act as a proxy service and they take up to 70% of revenue. They usually have a small coverage of mobile carriers they work with. Also there is a very high rate of returns/chargebacks, as end-user is always right even if he completely abused your service or software :-(. We wanted to use such service to let our customers recharge their balances in our system with a single SMS sent. After I studied this subject (for Europe, have no ideas about US) we abandoned the idea as completely profitless. If you find out anything with better conditions, please let me know. |
How would you implement a small-scale EBay? | webwright: I would go to hotscripts.com or drupal.org and see if there is already something pretty close. |

How many of you willing to give gmail/yahoo info to expand the network | wumi: who is this product targeted at? many hackers don't give out their emails, import contacts, but if you've received email spam from your other friends, you probably know they will willingly do so ... |
How would you implement a small-scale EBay? | Zak: I did something very similar a couple years ago. Details are covered by an NDA, but the software stack consisted of SBCL, TBNL (now Hunchentoot), CLSQL, CL-WHO, PostgeSQL and a few other random libraries. The archetecture was informally MVC. |
I want to add SMS to my service, tips/help/advice? | phpdev: I recommend Zong.com - They specialise in this and have an API. |

E-mail invites to our closed alpha. How to gather? How to send? | ra: I've been using crm.zoho.com - it has a web-to-lead form, which adds the details as leads in the CRM. I can then contact them via the CRM, or extract them all using the REST APIedit: BTW: it's free |
I want to add SMS to my service, tips/help/advice? | bluelu: This is called premium sms. There are lots of providers out there offering a service for this. |
E-mail invites to our closed alpha. How to gather? How to send? | quellhorst: Why not be different and have an open alpha? |
I want to add SMS to my service, tips/help/advice? | iloveyouocean: How to go about this (generating revenue from Premium SMS transactions):1) Secure a 5 or 6 digit ShortCode from Neustar(the only seller of shortcodes, usshortcodes.com) This will take approximately 1 month and cost $1000/month billed in 3 month intervals. Premium messaging only works with a shortcode, so this is necessary.2) Secure a contract with an SMS provider. I strongly suggest m-Qube, which is now owned by Verisign. Their service is excellent in every way. Great APIs, superior uptime and performance, superior support, very competitive rates, excellent relationships with the carriers.3) Draft a 'Program Brief' following the carrier guidelines, that explains your application. These guidelines are very specific (things like how you offer the ability to opt-out, advertise your tariffs, etc.) and your application must conform to them perfectly before the carriers will approve it.4) Submit the Program Brief for carrier approval. This process takes between 1 to 3 months depending on the nature of the application, particular carrier, etc. The approval process may, and often does, include redoing some of your application to suit the carriers.5) Assuming all the carriers approve your Program Brief, you can then start charging users when you send them a response. (sending a message is the only event you can charge a premium tariff for).The carriers each have a specific revenue sharing breakdown that is dependent on volume, price point, etc. In the case of m-Qube, they also take a small cut. Negotiating directly with the carriers is another endeavor entirely that I dont have any expertise in. |
Digital Signal Processing | menloparkbum: I liked this bookhttp://www.amazon.com/Understanding-Digital-Signal-Processin...Also the 2nd volume of "Musimathics" by Gareth Loy has a good introduction to DSP in the context of music and audio.http://www.amazon.com/s/ref=nb_ss_b?url=search-alias%3Dstrip... |
How would you implement a small-scale EBay? | keefe: It seems that payment processing is the biggest issue here. People are very reluctant (rightfully so) to give up their financial information, so I think it is a good idea to start with an existing service like PayPal or amazon FPS. Next, I would select frameworks based on the development environment you're most familiar with. I might choose java/spring/hibernate/struts2 or even raw jdbc and servlets because I've spent so long in the java world, but many in this community would probably lean towards RoR or similar. I think it's almost always easier to go with what you know. |
What should I try to do while still in college? | izaidi: Get heavily involved in a campus organization that suits your interests. If such an organization doesn't exist, start one. |
What should I try to do while still in college? | spencerfry: My biggest regret from college is not getting more involved with the activities/groups my college offered. I was plenty active around campus socially, but I was only in one group my entire four years. (Well, two if you consider being a computer assistant a group.) You will gain a lot and not feel as if you missed out on what your college has to offer by participating -- not to mention all the friendships you'll build in the process. Get out there and join groups! |
What should I try to do while still in college? | wallflower: #1 regret (which I will probably make up, job quitting possibilities) - Not going abroad - Doesn't necessarily mean studying abroad but traveling for month+ outside your home country during inter-school summer vacations |
What should I try to do while still in college? | alaskamiller: What's your ADHD symptoms like?I remember a period of my life where I would have to spend hours on a single page of a book because I wasn't able to retain anything. I should have went to the doctors about it. |
What should I try to do while still in college? | slackerIII: If you want to do the startup thing, notice people who are smart and more ambitious than you and spend your time hanging around with them.If you want to have your pick of a quality corporate job and find your excitement elsewhere, build something tangible you can point to during an interview. It doesn't have to be complicated, it just has to indicate that you can accomplish something on your own.Remember that becoming an expert in anything takes 10 years, so assuming you are around 20, think about what you would like to be an expert at when you are 30 and start working on it regularly.Edit: One more thing -- college can be one of the last times in your life when it is trivial to make new friends. Make as many as you can, and try to hang onto the good ones after you graduate. |
What should I try to do while still in college? | dkokelley: I'm in the same boat you are, my friend. I'm taking two classes over the summer to start my Jr. year on time.While I can't give you advice from historical experience, I can tell you what I'm doing.Right now I'm using this time to save up some money. I know that I ultimately want to start a company, but I don't know what type (startup, lifestyle) or even in what industry. I do know that I like technology, but I don't think that I would be able to use my skills to compete in that industry, though I may be able to use my knowledge there to give myself an advantage somewhere else. Right now I'm doing what I can to see what my interests are, so that I have a plan after college.I see college as two things: A way to meet people and build my network, and a plan B should the "own my own business" plans fall through. |
What should I try to do while still in college? | boucher: If you're planning on a career in programming, I'd recommend trying to get an internship somewhere before you graduate. If you think you might want to start a startup, go that route, but it won't hurt to do an internship at a big company either (it's actually probably better than working at one after you graduate, but I wouldn't know first hand).If you want to go the startup route, I'd recommend just sending emails to a bunch of startups you like. Most of them probably aren't actively seeking interns, but would be at least intrigued by the opportunity. |
What should I try to do while still in college? | ctkrohn: See what else is out there. Computers might be fascinating, but until you learn about a bunch of other fields, you will never know if they're what fascinates you most. Take as many classes as you can in as many areas as you're interested in, and be sure to take lots of classes outside your major. Finish more than one major. Join a sports team or club where you'll meet people you wouldn't otherwise. Save the specialization for your senior thesis, grad school, or for your job. Try to meet people with a wide variety of interests, so you can make a truly informed decision between majors and career paths.Others may tell you to choose an field of study early on and become an expert. I definitely admire that goal, but I don't think college is the place. Most underclassmen have no idea what really interests them; I certainly didn't. |
What should I try to do while still in college? | Kevin_Johnson: First off, since your a sophomore, your plans will change. Bet money on it. Don't get caught up in specifics of where you want to be. Instead take advantage of the powerful abstractions where you can to work out what "axioms of life" you want to design your life with. That's your homework assignment in the unwritten curriculum of the university. The vast majority of people fail that lesson, good folks recognize it and get it partially right, the great people master this lesson, implement, and refine it for the rest of their lives.Always consider your personality. My regret may be exactly what you DON'T want to do. Having said that... Being a physics students at very good engineering school, and having participated in student design competitions my only regret is not having taken more pure mathematics. In science and engineering, if it works, there's your evidence. You have shown it can happen. Mathematics I viewed, at the time being so simple minded, as a set of neat tricks for solving physics problems (or engineering problems, which at the time I thought of simplistically as merely applied physics problems). The reason I regret not taking more pure math isn't the theorems or skills I missed getting, it was the mindset. Every profession and field looks at the world in a particularly special way. It's a more abstract version of the saying "If all you have is a hammer, every problem looks like a nail." I'm actually doing research in graduate school now in mathematics and I'm really glad for it. The perspective from being a bit physicist, a bit engineer, and now a bit mathematician really gives one a lot of versatility, and that's where the variety of experience in the "hard subjects" pays off. You see, everyone who has specialized to be only one thing, think university professors, are like shaft mines. The specialists dig deep to get at the really rich seams, but they pass by a lot of pretty good stuff following the very richest dig through their subject. Take a bit more breath in your studies and you will see lots of good stuff, and how it's connected together.Finally, have fun too. Every day of my undergraduate schooling was a cycle of learn, work, play, build, fight, drink, sleep, and repeat tomorrow. It's the best that could have happened in spite of being exhausting, all consuming, obsessive, and unrelenting. I loved it because to me that is fun.Best of luck to you. |
What should I try to do while still in college? | Ravenlock: Do as much extracurricular stuff as you can manage with as much time as you can give it, in whatever interests you. I was also a CS major, and my free time went to theatre. I actually ended up with two degrees, the second one being theatre, so I guess for me it was a little more than extracurricular, but the point stands. Now that I'm out of college and have a wife and job, I find it infinitely more difficult to find time to do any acting/directing/etc, and it's something I really miss and I'm very glad I did it in college while I had the chance.Might not be theatre for you, obviously. Might be music, might be hiking, might be journalism, might be Ultimate Frisbee playing, whatever. Find something that isn't related to what you'll end up doing 9-to-5 after you get out, and explore that thing.EDIT: slackerIII's point about making new friends is also spot-on. Luckily, extra-curriculars can make that easier so the two tips go hand-in-hand. ;) The social atmosphere of college is completely unique (at least in American society; I realize you may or may not be US-ian), so open yourself up to it and take advantage. |
What should I try to do while still in college? | gm: Do EVERYTHING you can that will not be economically feasible (travel for a month or three) or even possible (spend a summer at Cambridge University in England). You will live to regret not doign these things when, after you get a job, you get two measly weeks of vacation per year.Use it all up: take extra classes, join a club, make a friend from another race, etc... |
What should I try to do while still in college? | auston: I'm 21 myself, so I don't know if I qualify as an advice giver but...If you want to meet like minded people, you've started in the right place.With this in mind, depending on what metropolitan area you are in/near there should be events... like BarCamp [http://barcamp.org/] or Refresh [http://refreshingcities.org/].Traveling is definitely something I recommend as well. |
What should I try to do while still in college? | menloparkbum: Go out with as many women as possible. Once you join the startup life the women will be few and far between. |
How would you implement a small-scale EBay? | aneesh: More importantly, why do you want to create a small EBay? EBay works because of it's size & scale.The hardest part of this would be handling the actual payments. The rest of it can be done with whatever you like best.Edit: After I wrote this, I realize it's pretty similar to Keefe's recommenation |
What should I try to do while still in college? | sah: Travel while you can do it cheaply. Take as many electives as far outside your majors as you possibly can without graduating later; college is better at giving you exposure than skills anyway. Make friends that you want to have parties with. Meet people who do things you know nothing about; you'll have fewer chances to do that in the working world.Drop out if you know you have better things to do with your time, and you can spend time around a large group of people with varied interests anyway. |
What should I try to do while still in college? | tialys: Wow... you sound just like me. I have the same issues with working, and the same desire to work in startups or similar. Honestly, I think it helps a lot to know that I'm not alone.I actually just got this account as I only discovered this site a few days ago (and I love it!) so I don't know if there is an easy way to get in contact with you, but I think it would be interesting to get your name and maybe an AIM screen name or the like.My advice? Make friends, and do whatever whenever while you can. Also, I have an internship in a big business now, and I hate it. It's boring, slow and totally uninteresting. Still, I'm glad I did it. It's something worth experiencing and it's given me new motivation to get good at something and start a business. Find out what you want, and don't stop until you get it -- even if you hate it, the experience is good. |
What should I try to do while still in college? | Spyckie: College, after sophomore year, tends to be less about the classes and more about the people. Choose as many classes as you can solely based on the professor's character/infamy. Those people will inspire you and help you choose what is interesting.Also, try to see as much of the world as possible, and this doesn't just mean traveling. I'm thinking about people like this person at TED: http://www.ted.com/index.php/talks/view/id/233 - try to find these people and get connected with what they're doing. |
What should I try to do while still in college? | thomasswift: take art 101 or design 101 or calligraphy 101, something that forces you to learn the basics of design and composition. |
What should I try to do while still in college? | SCVirus: Smoke weed (or do tantric yoga) until you become conscious on a new level (you'll know when you have, if you have difficulties smoke more stronger weed, hash, oil, use a vapourizer or take it orally after extracting it with fat (bake < 300f) or alcohol).Take mush (of the psilocybin variety) until you understand the nature of the change in consciousness created by the mary jane.(you can try mescaline anytime after mush if you so wish, it will likely help you either understand the changes or find the connection, but would likely be counterproductive before mush is taken in a significant dose)Take LSD until you feel an unshakable connection to the universe (start with a massive dose, theres no time like the first, listen to The Beatles [anything after Help! is best] and The Doors for assistance 'breaking on through to the otherside').Then smoke DMT until you reach 'DMT hyperspace'. (Do not let fire touch the DMT, only touch the flame to the glass [and even then not /right/ under the DMT] take big hits you gotta take 3 big hits and hold them in before you become unable to smoke [mildly difficult]; keep trying.)At this point you will understand your consciousness in a way science could never teach you, and you won't have to ask us anything about what you should do, you will already
know. |
What should I try to do while still in college? | Prrometheus: Participate in the COMAP Mathematical Contest in Modeling. It was the 4 best days of my undergraduate career. I did problem B in 2005, here's a link to the problem set:http://www.comap.com/undergraduate/contests/mcm/contests/200... |
Avoiding carpal tunnel / repetitive stress injuries | adrianwaj: My solution was to place a standard building sized block of wood measured to the length of my standard keyboard under the keyboard so the nearest edge of the keyboard sits up on the block, and the furthest edge of the keyboard sits on the table as usual. This way, the wrists can rest on the flat upside section of the wood with the fingers then drooping over onto the angulated keyboard. It's meant to simulate how your arms and wrists feel when you hang them down freely - no flexion of the wrists up or down, and relaxed.Similarly, place a thick book near your mouse for your wrist to wrest upon, leaving your palm to drop onto the mouse which slides on the pad that sits on table. For me, smaller mice are better that can be moved with just the fingers and highly sensitized.This solved the RSI in my forearms.Note: The wood block must be the correct size so that the keyboard slants neither too high nor too low, and that the forearms do not touch.I use: '2x4 (pronounced "two by four"), but few people realize that the actual height and width of a 2x4 is really somewhere close to 1 1/2" x 3 1/2"'

Avoiding carpal tunnel / repetitive stress injuries | Stabback: I just went to a physiotherapist about this very issue, here's what I was told.First, I've been experiencing a dull pain shooting up the BACKS of my hands to my wrists, following the middle finger. This may or may not be what you have, and I recommend looking into this yourself. It cost me 80 CAD to visit a physiotherapist and it was worth every penny. If you are going to be typing for the next 5, 10 years or longer (here's hoping we get a better input system...) I urge you to visit at the first bit of pain.Onto the diagnoses. A primer on the human body: the nerves and blood vessels that get to your hands come from your spinal cord. To get there they must pass under the collarbone and above the first rib. My problem is that I have a slight posture problem (no one has ever noticed it) where my shoulders slouch forward a bit. This is very common for people that use the computer a lot, and it was compounded by my height (6'3''). As I am a tall person, I slouch while talking to people, inspecting things, pretty much whenever I do anything in a world built for the average sized guy.This posture problem results in a small constricting of the space between the collarbone and the first rib - putting pressure on the blood vessels and nerves going through there. This causes extra strain whenever you pull on these items (which you do while moving the fingers). To make matters worse I do not do a lot of upper body exercise. I run 3k a day and bike about an hour and a half, but none of these tasks work my back muscles. While typing for extended periods of time these muscles recognize they are not needed and 'shut off' to conserve energy. If they were used more they would not be shut off as quick. When they are shut off the shoulders slouch more.I was recommended a series of stretches to help the constricting of the blood vessels and nerves. I was also recommended to start swimming regularly to build muscle. I have also started using the program "instant boss" (quick and dirty program) to have a 10 and 2 schedule - 10 minutes on and 2 off. I follow it religiously.I'd define the stretches but my hands are hurting a bit and I need to stop typing. I do recommend seeing a physiotherapist yourself though to get customized stretches that fit your body type. Take breaks, really read up on ergonomics.Hope this helps. |
What should I try to do while still in college? | tlrobinson: Others have suggested great things to do outside of class, but I have some related to CS.Take a compiler course (or several). This really should be required, but unfortunately it wasn't at my school until after I graduated. Also, lots of algorithms and other "real" CS courses. Now is the time to learn that stuff.Avoid the "trendy" courses (Stanford Facebook application class, I'm looking at you) and go for the hardcore CS stuff. The rest you can easily learn on your own, but I found having a professor and structured course was invaluable for the CS topics.Of course everyone is different, but that's my opinion. |
Avoiding carpal tunnel / repetitive stress injuries | DenisM: 1. Ergonomoc evaluation by a specialist to set up your desk, monitor etc. Ask your employer, they should provide it.2. Inquire about work-place injury laws in your state. Your employer will likely have to pay the expenses.3. Record all expenses no matter who pays for them. If you become disabled reciepts may help to make employer shoulder part of the weight.4. Physical therapy. It's important to continue excersizing until, well, forever.5. If mouse is source of your problems try using two mouses alternating left and right hands. You'll get used to it.6. Carpal tunnel and RSI are two very different things. It's important to see specialist to tell one form the other. Carpal tunnel is actually quite rare, but consequences are severe. |
Avoiding carpal tunnel / repetitive stress injuries | tortilla: 1) Get a mouse that's flexible enough to use with either your left or right hand. It might feel weird at first, but switching sides every hour will reduce a lot the pain. Takes a bit to get used to but you'll eventually adjust.2) Try to use the keyboard as much as possible for everything. Go into your Keyboard & Mouse settings and enable full keyboard access (or ^fn F7 to toggle on/off)3) Use either Firefox/Camino for you main browsing because you can enable "find as you type" which you can use to navigate the links on a web page.4) Take regular/breaks. I use http://tech.inhelsinki.nl/antirsi/ to remind me at set intervals.5) Exercise regularly (running, walking, golf, something to get you away from you computer).6) Meditate, relax, listen to music. Whenever I feel like I'm tired or overstressed, I listen to this for about 20 minutes. I'll feel refreshed and much more focused.
