Quick first glance feedback on the page, take it or leave it:
a) "the easiest way to" lowercase start and then "Write your life story"
uppercase start. Seems weird to me. The other way around or both uppercase.
b) Top bar seems empty, maybe an actual logo (that adds some other
color/shade) would chance that.
c) "See an example" needs no-Javascript fallback. I assumed a video behind it.
Pleasant surprise to see something that finally showed me what it is all
about. I strongly suggest not hiding that. It is below the break for me and
adds a lot.
d) Ned Flanders takes away the credibility and earnesty the page build up so
far. Bad!
e) "private, secure, & friendlier", the comma after secure seems out of place
to me. I am not an english native but from what I know it would be more normal
without it. "friendlier" is not a word, is it? Also, how is it secure if you
do not tell me how you actually secure it (both for normalos and hackers
please)...?
f) entry is a bad empty word. I guess you already tried to find a better one.
Can't think of one myself. :-(
g) "a personal journal that you'll love to use" = you love the journal
"why you'll love us" = you love the company
h) "Oh snap, remember this?" same as Ned, does not fit the otherwise very
noble theme at all.
i) The open book has a weird shape. Does not feel right to me. Maybe if it was
taller?
x) No privacy policy (as a techie "only you can see your entries" screams for
encryption against YOU (and/or hackers, this is important)), no contact, no
nothing to make it human.
y) Privacy tainted by Google Analytics.

ugh
Re: e) (This is purely my personal opinion, but …) Anyone who uses the serial
comma [1] must be seriously insane. How can you? Doesn’t your brain explode?
(Calm down, calm down … [2] … there, better.)
Friendlier is indeed a word, the comparative of friendly.
Amazing idea, by the way, beautifully executed and immediately captured my
imagination.

I notice that a huge part of my daily life is recorded in email conversations
with other people -- it would be cool if I could forward a conversation to
[email protected] and it would automatically make it a part of my journal and
make it aesthetically pleasing at the same time.
Great job on the execution of this app. I have talked to others who have had
this same idea, but their execution was ugly/unexcting/etc. This is clean and
simple.

Taking your thought a step further, let's also save the comments you make on
others' blogs and bring them into your journal/blog as well.
At the end of the day, I don't need another blog or a slight variation on
blogging technology. I need something that basically blogs for me. If I can
add value to my site by adding comments like this one to other people's sites
(then pressing this "magic" button (maybe a bookmarket?) to automatically save
it as part of my blog), that'd be pure awesomeness.
Beyond saving boatloads of time for everyone who used it, it would create a
more connected blogosphere by allowing people to link their commenter accounts
(like HN, Reddit, etc) to their primary blog...effectively giving people more
ownership over the things they write on others blogs, increasing author
recognition, etc.
~~~

_I need something that basically blogs for me._
Tumblr is pretty close to doing this, but the problem is its just context-free
noise. It's echoes from a very, very noisy set of interactions that you
perform. I had a Tumblr blog that harvested photos, blog posts, Twitter,
last.fm etc etc. and it all meant absolutely nothing.
This isn't really blogging, it's journaling. Writing a diary is supposed to be
therapeutic because you're writing down the things you dare not talk about
with others (maybe not even your SO). It's not about what you do, it's about
how you feel.
That's why I would like to see encryption mentioned somewhere, and pushed
hard. I wrote one entry to see how it works, but I'm going to disable the
notifications until I know that my personal outpourings are not actually being
read by others.
------
sgupta
Hey HN - we made this in our spare time, just because it was something we
wanted to use. When we told some friends about the idea though they wanted to
use it too, so we decided to release it. Many thanks for checking it out.
~~~
evandavid
I love the idea. Love it. Like, really excited. However, I'm not prepared to
use a service like this in a hosted environment. Too many risks: you go out of
business, security, privacy, etc. Plus the information just feels to personal
to be sitting on someone else's server. I would love to see a quick daily
prompt like this added to Macjournal or similar software.
~~~
evandavid
That said, I'm sure there is a target market out there who will be more than
willing to use the product in its current format. I'm looking forward to
seeing where this idea goes.

Accept PGP-encrypted mail seamlessly and you won't need a privacy policy
except for those who like throwing their lifelog at random strangers. Be sure
to use PGP/MIME to include the old message in your mailing.
Of course, setting up PGP, let alone remembering the passphrase (gasp) is a
lot to ask of the typical user who needs to use his mail client as a text
editor.
Otherwise, it's a cute idea, really. Please excuse cynicism.

The design is beautiful, but why would I use this over WriteRoom? For years
now, I've been writing at least 500 words in WriteRoom every single weekday,
and I'm closing in on a year of doing it (and a bunch of other habits) without
missing a single day. It's not that hard, I know I'll probably never lose my
entries (time machine + dropbox backups), and my privacy is more assured. I'm
just not sure I see the advantage here...

First of all, fantastic design!
Is there any way to export posts - for example, if I wanted to share them with
a significant other or another family member?
Also, and this is mainly curiosity, how do you handle sending posts from the
past for the first few days where there really isn't much history?
~~~
sgupta
Thank you!
We don't have export yet, but we've definitely wanted to share some of our
entries with close friends and family too. We'll be brainstorming around this!
Regarding past history: For your first week, we just send you your entry from
the previous day. After you've been using it for a week though, and some
history has built up, we'll show you entries from a week ago (and then a month
ago, etc.).
Thanks for checking it out - really appreciate it!
------
thingie
It'd be nice to have some export feature. After few months, if I will use
this, you are going to have quite a lot of entries from me, and all of them
are important to me, I don't want to lose them, so I'd like to be able to
easily make backups to my own computer.

I like it, and I signed up. I don't want to get emailed at 8pm -- that's after
my internet cutoff, so I faked a timezone. But, it would be nice to just
choose a time.
Also, who did your webdesign? I like it!

We'll be adding the ability to change when the email is sent, and it should be
out by next week. Clever workaround though!
And thanks for the design compliment! We did it all in-house, so we really
appreciate the kind words.

pclark
This is really cool. I'm curious if _you_ can read the entries?

sgupta
Thanks for the kind words! We're currently working on encrypting the entries -
this is an MVP and we initially wanted to see if people like the idea.
~~~
martey
It does say on the home page that "Only you can see your entries." If they are
not currently encrypted, that would seem to be untrue.
~~~
colonelxc
Even if they do encrypt it, they will have to be able to decrypt them server
side to send you your month old posts. That means the owners are technically
capable of also reading all of your posts.
~~~
mbenjaminsmith
That's not entirely true. If this were purely a web-accessible blog, there's
no reason you couldn't encrypt/decrypt this in the client (sending and storing
encrypted text). You'd have to throw out email posting in that case though.
~~~

I think you're on to something. I look forward to the day when we are shocked
by unencrypted private data accessible on the server as we do un-hashed

How exactly is this service better than, say, a simple text file on my own
machine with a daily reminder set up through some other means?
Why would I want to use some third-party website for something so simple that
I might as well do it myself? I can see some pretty annoying downsides (need
to have a crypto layer because I don't want you to be able to read my journal,
need to export regularly the data to my own computer because I don't want you
to be able to lose my journal), but no real advantages (it's not even more
convenient!).
In any case, I believe that the two following statements, at least, are plain
wrong:
\- "The easiest way to write your life story": no, the easiest way is to fire
up a text editor and start writing.
\- "Only you can see your entries": should read "Only you and us can see your
entries".

I like the daily emails as I don't visit too many sites daily, apart from HN

how regularly I'll do this, but time will tell.

mini feedback on home page: The 'see example' link needs to scroll the page

I think the vertical spacing between the various components is too much. If
you could move things up a bit it would work real well. The colors, fonts, and

so much.

Additional info (from the e-mail I received) in case anybody cares:
"P.S. Please note that the reduced bandwidth rates shown above will also take
effect for Amazon EC2 and Amazon SQS. The bandwidth tier in which you will be
charged each month will be calculated based on your use of each of these
services separately, and could therefore vary across services."
------
yaacovtp
Can anyone tell me what bandwidth costs a month once you need over a terabyte
a month? How would you host a 5-10 mb movie that may be viewed millions of
times without using a 3rd party video host like youtube etc?
~~~
especkman
Lots of dedicated hosts will include a 2-5 TB of transfer a month for
$100-500. Media temple will sell 1TB chunks on shared hosting for $20/month.
I've seen dedicated hosts that price bandwidth above their included allotment
at $500 per TB. You can also buy based on peak bandwidth.
You'll see quite a range depending on business models, peak transfer caps,
etc. Mediatemple, for example, is clearly hoping that most people will never
need their full allotment, and when they do, they only need it occasionally.

I recently spoke to a few people who have worked on these large scale

projects. These projects have change orders alone worth well into the 10s of

get completed at all.
I don't find the choice of photos particularly inspiring, from an artistic
sense, but it is nice to have a peak into that world.

First photograph of light as both a particle and wave (2015) - ThomPete

"A clever technique and an ultrafast electron microscope have caught an image
of light behaving as both particle and wave at the same time. Here, the wave
nature is demonstrated in the wavy upper portion, while the particle behavior
is revealed below, in the outlines showing energy quantization."

deckar01
It took me a few reads for this to sink in.
Quantum interference causes standing waves. Electron-photon particle
collisions cause detectable energy release. The particle collisions occur in
an interference pattern.

EarthIsHome
Yes, and the colors describe the speeds of the particles as a result of tbe
electron-photon collisions.
It's not necessarily the particles we're seeing, just the particle behaviors
from their collisions.

~~~
leksak
Yeah, I don't know how to interpret it. It's not immediately obvious to me
that I'm looking at a wave and particles at the same time.
~~~
URSpider94
What the image represents is the energy loss/gain of a whole bunch of
electrons that interact one at a time with a light wave traveling along a tiny
metal wire (we call this kind of captive light wave a "phonon").
For each electron fired at the wire, it can either pass through unscathed, or
it can interact with an electron and scatter off with a different energy, like
two billiard balls hitting each other. The collision is fundamentally a
collision between two particles. However, the fact that the properties of the
collisions vary sinusoidally along the length of the wire imply that the
photon is also acting like a wave oscillating up and down the wire.
I disagree that this is the "first time" that we've observed simultaneous
wave-particle behavior, you can see the same thing by firing photons at two
narrowly-placed slits. This results in a diffraction pattern as if the photons
were interfering like waves, but we can confirm that we're detecting single
photons at the detector, and you can even confirm that each photon travels
through one slit or the other ... See [https://en.wikipedia.org/wiki/Double-
slit_experiment](https://en.wikipedia.org/wiki/Double-slit_experiment)
~~~
AnimalMuppet
One nit: A phonon is a vibration of a lattice, not light.
~~~
URSpider94
Yep, that should have said "plasmon". I messed up all of my comments on this
thread. A plasmon isn't technically light either, it's an oscillation of the
electric field in a conductor -- but it has wave/particle duality like a
photon.
------
emerongi
It's hard to grasp what was really captured on that image, but this still
doesn't rule out the pilot wave theory. I think it's misleading to call it a
photograph of light "as both a particle and wave".
------
amelius
I have a question about QM, which perhaps somebody here can answer: Is
quantization an inherent property of the photon, or is it a property of the
material (or of the interaction with it)?
~~~
URSpider94
The other answers posted here are not quite right. Light energy is indeed
inherently quantized, and a photon is one quantum of light. In other words,
you can't have a half-photon of light, only even multiples.
Einstein wrote the equation "E = h*(nu)", where h is the so-called "Planck's
constant", and nu is the frequency of light. Translated, this means that each
photon carries an amount of energy proportional to its frequency, higher-
frequency photons (IR -> red -> blue -> UV -> X-ray) carry more energy.
tl;dr: Quantization is an inherent property of light.
~~~
amelius
> E = h*(nu)
Yes, but the question is whether that is due to the material not being able to
produce non-quantized photons. Stated differently, suppose we had a different
way of generating photons, then could we theoretically create them in a non-
quantized way?
~~~
lisivka
Yep. They called "radiowaves".
~~~
amelius
Sounds logical, but then again, how fundamental is the "Q" in "QM"?
~~~
lisivka
Extremely. Broken quanta will release its energy. Check solitons (example:
[https://www.youtube.com/watch?v=JD32kkoFU3Y](https://www.youtube.com/watch?v=JD32kkoFU3Y)
). Soliton wave can cross ocean, but if you broke it pattern, you will have
regular waves, not a half of solition.
------
shshhdhs
This is really cool! What's the reason for the blue & violet colors to be
raised more than others in the wave?
Is it just the timing of the snapshot? As in, another picture might show
another color at the top of the wave? Or is the standing wave "stuck" in that
position?

Switch generic icon to negative feedback for non-https sites - diafygi
https://bugzilla.mozilla.org/show_bug.cgi?id=1041087
======
codezero
There have been a few times when I've got a legitimate red icon for bad
certificates and what not. Pushing this to the rest of the web will mean I'll
miss real errors through the noise because they happen so infrequently that
I'll just stop checking if every website has a red icon.
~~~
briansmith
Browsers completely stop the page from loading and show a full-page error for
a certificate error. There's a huge difference between that and a small icon
in the location bar. Plus, if the red icon that is suggested in that bug
report is too loud, a less loud indicator could be used instead.
There's a lot more to designing a UI for this than just changing the icon. For
example, when you type "foo.com" into the address bar, browsers generally
default to "[http://foo.com"](http://foo.com") instead of
"[https://foo.com."](https://foo.com.") And, consequently, browsers tend to
show "[http://foo.com"](http://foo.com") as "foo.com" to suggest that you
don't need to type the "[http://"](http://") part. All of that needs to change
to become a lot smarter in order for this type of idea to succeed. However, it
doesn't seem completely unreasonable to consider making all those changes. In
fact, I think these changes should be a high priority for browsers makers.
tl;dr: I suggest people brainstorm ways to improve upon the idea to make it
workable, instead of trying to shoot it down.
~~~
codezero
Honestly, I'd prefer a heuristic that could determine whether https was
significant on the current URL. Are there submitted values, cookies of
importance, get parameters? There are a lot of reasons https is important and
there are a lot of places where it's totally not important.
If you draw people's attention to something that isn't seriously important,
then those times when the whole screen sends a warning you go, "oh well, I had
that red warning going all along and it didn't matter, so why do I care?"
I am saying that by pushing a warning where it's not necessary, you diminish
the value of any warning.
~~~
briansmith
> There are a lot of places where it's totally not important.
See my other replies on this page for some reasons why I think there are no
pages where HTTPS is not important.
I agree with you regarding the UI issues and the potential to generate apathy
by crying wolf. That's why I think that the specifics of the linked-to
proposal won't work. But, I think the general idea is worth investigating. It
just requires some user research.
Also, the fact that browsers support a non-HTTPS mode at all is really the
bigger UI issue. Imagine if HTTPS was the only option. The biggest UI security
problems would instantly vanish! That's a big reason why a lot of people are
actively working so hard on finding ways to make HTTPS work for everybody on
every site.
------
mplewis
Putting a red icon on 90% of all websites means the meaning of the icon will
just saturate and people won't pay attention to the red icon any more.
~~~
briansmith
FWIW, ~33% of all pages are loaded over HTTPS already in Firefox, according to
the metrics collected by the browser. And, over 50% of all HTTP requests
(including subresources like images and scripts embedded on a page) are over
HTTPS, again according to the usage data collected by the browser.
~~~
scrollaway
I'd be willing to bet quite high all these HTTPS requests are all on the same
specific services (facebook, gmail, google would already take most of them).
------
danso
No.
Not all sites exchange data worth the SSL-layer...let's say, 30-50% of the
sites...that means for roughly half a user's non-email/social-networking web-
browsing, they're going to either be saturated with a warning message that, if
psychology research is to believed, is going to be promptly ignored like your
apartment's super-sensitive smoke detector or the boy watching out for wolves.
What's the actual reasoning in OP's mind here? That the average web user is
someone who, when the computer gives some warning sign that is disconnected
from any kind of discernable threat, that the user will automatically take it
seriously? That they'll demand to know why they're in danger, and then will
rise up and petition the Internet regulatory commission to make all sites do
what it takes to make that red icon go away, and the web will be more secure?
I don't want to be overtly negative towards well-intended idealism, but this
is such a bizarrely naive viewpoint that it must be openly challenged. That,
and it just blithely ignores all the research showing what happens when humans
are overloaded with impotent warning signs. This is the kind of idealism-
without-consequences that can end up causing more harm than good.

Not a bad strategy. Until the website owners take the path of least resistance

You're answering "why" instead of answering "why not" again. "Why should you

"but that'll never happen" retort to them.
Unfortunately, plaintext HTTP exists, so here we are, with me telling you that
the pro-gay rights piece you wrote on your static blog contains keywords that
make it be viewed as extremism/terrorism by Russia's automated monitoring
systems and anyone reading it gets immediately added to a watchlist.
Unfortunately, a few of your readers are from russia and six months later
those readers join a political protest against the killing of kittens or
something. Their government notices that and makes sure to "take action". And
to think HTTPS could have avoided that.

Locks come standard on every door, they don't expire after a given time and
every child knows how to use them. See how your comparison to acquiring,

> And to think HTTPS could have avoided that.
If the NSA tags people who look for info on TOR as extremists, an hypothetical
state might tag people who use HTTPS. And to think that HTTP could have
avoided that! I mean, if every argument is an hypothetical, anything is
possible.

If HTTPS is used globally, people can't be flagged for using it (or the flags

Which is better on Android: divide by 2 or shift by 1? - zdw
https://jakewharton.com/which-is-better-on-android-divide-by-two-or-shift-by-one/
======
anyfoo
Thorough work. Going back to the premise, I want to offer an alternative
viewpoint by asking whether, in the case of binary trees implemented by
arrays, “integer division by 2” of the array index is necessarily the best
interpretation of what you are trying to do here?
Instead, you can also see the array index as a bit string, where every bit
tells you which path to go down, left or right. In that case, “shifting right
by one bit” moves you up to the parent. “Shifting left” moves you down to the
left child. Flipping one bit flips you over to the other child. Bit wise
operations indeed seem more natural with that interpretation.
A lot of “power of 2” multiplication/division has similar interpretations. For
example, when walking page tables, you could see walking down the levels as
“dividing by the size of the granule”, or simply as “shifting right to select
the index on that level”.
No contest on anything where the power of 2 is coincidence, i.e. for non
“computery” things where there is no such underlying structure.
~~~
yiyus
I had a slightly similar experience at work. We deal a lot with angles and
binary angles are often the most efficient representation. Many colleagues
find it annoying because they insist on converting every binary angle to
radian or degrees, but if you actually interpret the bits as successive
divisions of a circumference, I actually find the binary representation way
more intuitive than a floating point number.
~~~
slavik81
That method is exactly equivalent to using revolutions as the unit with a
fixed-point numeric representation. Maybe your skeptical colleagues would find
that perspective more palatable?
~~~
yiyus
That's some good advice. Unfortunately, most of the people I work with do not
have a computer science background (they are materials scientists and
mechanical engineers), so they are not familiarized with fixed-point
arithmetic neither.

I appreciate the thorough exploration and resulting detail in this article.
Still, I find it a little sad that either the state of our toolchains or the

reduction will always happen, and developers need not worry about the cost of
expressing simple arithmetic operations in the clearest way.

I would go further in that many programmers don't understand the difference
between logical and arithmetic operations and why they exist.
I have had to puzzle over far too much code doing

I blame Java not having an unsigned type. There are apparently some weird
tricks you can do with arithmetic in Java that operate on things like an

Question from a perf noob: it seems like this in principle only shows that
there's no difference for a Pixel 3 because other Android machines could have
processors that have/lack an optimization for shift or divide. Couldn't a
different Android phone have different performance characteristics?
~~~
lgg
It is not that the processor that contains an optimization per se. The thing
to understand is that shift is fundamentally a simpler operation than
multiply... a shift can be implemented with a few transistors per bit and done
in a single cycle trivially. A multiply unit takes tons of transistors, and
often takes multiple cycles (this is a trade off you make when you design a
multiply unit, you can save space by making it work on smaller integers and
reusing it multiple times over several cycles to do multiplies of larger
integers, just you like you iteratively multiply digits one you do it on paper
by hand). Even on processors that have single cycle multipliers it takes a lot
more power to do a multiply than a shift because of all the extra hardware you
need to engage.
Since shifts are fundamentally simpler than multiplies it always makes sense
to do this transform. This is one of a number of transforms that are generally
called "strength reductions"
<[https://en.wikipedia.org/wiki/Strength_reduction>](https://en.wikipedia.org/wiki/Strength_reduction>),
converting for a more general expensive operation into a more constrained
cheaper operation. In this case it is the equivalent to knowing that if you
want to multiply a number by 10 you can just add a 0 at the beginning instead
of having to write all the work by hand.
The only reason not to do this transform would be if you had a CPU that
literally does not have a shift operation, but I cannot think of any such
part. Even if you did have such a part, the odds are you could emulate a shift
using other other instructions and still outperform the multiply.
This has been a standard optimization for half a century. The original C
compiler for the PDP-11 did these transforms even when you turned off
optimizations
<[http://c-faq.com/misc/shifts.html>](http://c-faq.com/misc/shifts.html>).
~~~
cogman10
> This has been a standard optimization for half a century. The original C

Consider this, a common easily applied optimization that compilers have been
doing for half a century MAY have made it's way into modern CPUs.
Transistors aren't nearly as power hungry as you paint them and CPUs aren't
nearly as bad at optimization. There is no reason to switch a multiply or
divide for a shift. The ONLY reason to make that switch is if you are dealing
with the simplest of processors (Such as a microwave processors). If you are
using anything developed in the last 10 years that consumes more than 1W of
power, chances are really high that the you aren't saving any power by using
shifts instead of multiples. It is the sort of micro-optimization that
fundamentally misunderstands how modern CPUs actually work and over estimates
how much power or space transistors actually need.
~~~
reitzensteinm
Since it's what I'm typing this on, let's look at Skylake.
Multiply: Latency 3, Throughput 1 Shift: Latency 1, Throughput 2
If the ALU contained an early out or fast path for simpler multiplies, the
latency would read 1-3. You can verify this by looking at div, which does
early out and has a latency of 35-88.
Any compiler that doesn't swap a multiply to a shift when it can is negligent.

I am really struggling to understand the benchmark output quoted.
Can anyone elaborate what does benchmark=3/4 ns mean, and the count? Is the
set-up part of the benchmark (test structure suggest not, but just to make
sure)?
The only way I can read it is that 4000 divisions takes 4ns, and 4000 shift-
rights takes 3ns, but that only has 1 digit of precision, which makes it
unusable for comparison, but even then suggests a 25%/33% difference, which is
not insignificant.
Also, the VM seems to optimise multiply out, so it must be doing it for a
reason.
~~~
thechao
It's definitely not 4000 divisions per 4ns — that'd imply a terahertz
computer. I think it's saying that the amortized cost of 4000 divisions is 4ns
per division. Small integer division is an "easy win" for a dedicated HW path,
so it doesn't surprise me that it's only a little slower than a shift-right.
Variable length right shifts aren't that fast.
~~~
bonzini
It's not small integer division that is being benchmarked, the JIT compiler
has reduced it to an addition, a conditional move and a right shift. This
sequence is then benchmarked against the right shift.

Everyone is talking about this microoptimization on the math of the access but
all I can think about is how the data structure you are building using this is
probably memory bandwidth limited and powers-of-two storage is almost
definitely going to cause some kind of cache line aliasing, so maybe you
should try something non-obvious like "division by 3" (after doing three key
comparisons instead of one) and see if it makes your algorithm much much
faster than messing around with a division by 2; there was even some good
analysis of this effect a while back I can reference.

There is no difference... because of the conversion.

Right: for now, in certain situations, on the tested toolchain.
Even ignoring those caveats, several commentators seem to have got the

These types of transformations are simple to detect, well known, and applied
by ~every compiler.
Unless you have evidence otherwise (ASM differences or benchmarks), there is
no use in manually transforming your arithmetic into something more complex
but faster. The compiler will do it for you.
~~~
sambe
I think that's a point which is bordering on religious - many people would
debate trusting the compiler, especially over time and more complex
situations.
I'd certainly tend to agree with you in general but more for the reason that
the compiler can abstract over hardware changes across time. I'd take that
benefit over the risk of the optimisation not being applied for most code I
write - non-optimisations would be considered bugs and probably/eventually
fixed.
I'd strongly disagree the code is more complex (in this case).
~~~
merlincorey
It especially seems religious to me because it's saying that somehow "/ 2" is
simpler than ">> 1" because it has one less character for the symbol, and
because division is a more commonly known operator to most people than bitwise
shifting.
It seems to me that they are equally simple if we assume that programmers
dealing with low level or performance intensive code know what a bitwise shift
is and ignore the extra character, then they are literally equivalently
complicated expressions with 1 symbol and 1 value applied to the symbol.
~~~
kadoban
Code does not happen in a vacuum. Which is more understandable/simple depends
on the domain of the code in question. Usually that's going to be the multiply
or the divide.

Right, but my statement was that the domain would be low level or performance
intensive code -- do you disagree that in that domain they are equally simple?

Isn't that the wrong direction for the optimization? I would assume you would
want to compile adding two numbers into shifting by one, not the other way
around.
(I know nothing about hardware, it just intuitively seems like moving a bunch
of bits over by 1 should be faster than dealing with xor and carries)
~~~
jcranmer
In hardware terms, adders are simpler than shifters. You can usually do both
in a single cycle, but it's going to be lower power to do the add instead of
the shift.
To put this in more concrete terms: an N-bit adder involves N 1-bit stages to
add each bit, and then a 1-bit carry network on top of that, which has N
stages in it. So overall, it's O(N) in terms of hardware. An N-bit shift unit
is going to use lg N N-bit muxes--or O(N lg N) in terms of hardware. Total
gate delay in both cases is O(lg N), but adders have O(N) hardware (and thus
energy consumption) while shifters have O(N lg N).
A secondary consequence of being larger area is that a superscalar
architecture may choose to have one execution unit that has an adder and a
shifter and a second that only has the adder. So an addition may schedule
better than a shift, since there are more things it can execute on.

O(N) adders cannot meet the latency demands of modern high-frequency CPUs. The
actual complexity of adders in real CPUs is usually O(N²).

Java is a hard-compiled language on Android since version 5.0.
ART, which replaced Dalvik on 5.0 (available as experimental on 4.4), was AOT
only up to version 7.0.
As it was proven that Android users lack the patience of a C++ developer when
updating their apps, Google adopted another approach with version 7.0.
A multi-tier compiler infrastructure, composed by a very fast interpreter hand
written in Assembly for fast startup, a JIT compiler for the first
optimization level, with gathering of PGO data, then the AOT compiler runs in
the background and when the device is idle gets that PGO data and just like a
C++ compiler with PGO data, outputs a clean AOT compiled binary for the usual
user workflow.
In case of an update or changes in the workflow that trigger the execution of
code that wasn't AOT compiled, the process restarts.
As means to reduce this kind of de-optimizations, since Android 10 those PGO
files are uploaded into the Play Store and when a user installs an application
that already has PGO data available, it is downloaded alongside the APK and
the AOT compiler can do its job right from the start.
In any case, he used _dex2aot_ which is the AOT compiler daemon on Android.
Microsoft has gone through similar process with .NET for UWP, with the main
difference that the AOT compiler lives on the Microsoft store and what gets
downloaded is already straight binary code.
Apparently mixing language capabilities with toolchains keeps being an issue.

How come the division is almost the same as the shifting? Is the CPU
pipelining the operations between iterations of the loop or something? There
is a direct data-dependency in those operations but not between iterations so

If it's signed int, unless you know the value is positive you can't just shift

Can't you do an arithmetic shift-right? That takes the sign into account.
~~~
jcranmer
No. An arithmetic shift right does a division that rounds down; an integer
division operation instead truncates (rounds to zero). The easiest example is
-1 / 2: -1 / 2 is 0, but -1 ashr 1 is -1.
To replace a signed division with ashr, you have to know that for all negative
inputs, the value of the bits shifted out are all 0.

compiler that generates PGO data as well, and an AOT PGO based optimizing
compiler capable of doing bounds check elision, de-virtualization, auto-

optimizations.
The PGO metadata files also get shared across devices via the Play Store as
means to steer the AOT compiler into the optimal level of optimization across
all users of the application.
I assume that at the current level of ongoing ART optimizations, the team
would consider that a compiler bug.

Yeah but you should also then understand what will yield real results, and >>1

e.g. continuous memory is more important than ever. You will not optimize a
lot by attempting micro techniques from 30 years ago.
Other random example: in some edge cases, integer division replacement by a
multiplication _can_ still be relevant today (depends on if its a constant,
the compiler, and if nothing optimized also on the exact processor, though,
because last models are already ultra-fast with the real integer divide
instructions), but I suspect in 15 years (maybe even 10) this will be
completely irrelevant, at least for high perf targets.

------
fefe23
A few points.
1\. Looking at the Java bytecode is practically meaningless, you would have to
look at the machine code the JIT is creating.
2\. A division by 2 is identical to a shift right by 1 only if the integer is
unsigned. Java integers are signed. Try this program in C to see for yourself:
int foo(int a) { return a/2; } int bar(int a) { return a>>1; }
Run gcc -S -O2 to get assembly output in text form.
Basically, the problem is this:
5/2 -> 2 (ok, rounds down)
5>>1 -> 2 (ok, same)
-5/2 -> -2 (ok, rounds down)
-5>>1 -> -3 (oops!)
3\. The question is really about the JIT backend for the target platform,
which means CPU platform, not OS platform. So "on Android" does not make much
sense here, as Android exists for x86 and ARM and those JIT backends might
behave differently.
~~~
anyfoo
All things directly addressed by the article.
------
devit
Honestly, it's hard to read this article and not question the author's mental
state or intelligence.
He literally presents x86 and ARM assembly dumps where shift right generates
one instruction, and divide generates that same instruction plus several
others.
Then, he feels the need to run an unnecessary benchmark (most likely screwing
it up somehow) and concludes there is no difference!
But how can there possibly be no performance difference, in general, between
the CPU running an ALU instruction and running that same instruction plus
several other ALU instructions?!?
It's almost unbelievable.
As to how he screwed up the benchmark, my guesses are that either he failed to
inline the function (and the CPU is really bad), or failed to prevent the
optimizer from optimizing the whole loop, or didn't run enough iterations, or
perhaps he ran the benchmark on a different VM than what produced the assembly
(or maybe somehow the CPU can extract instruction level parallelism in this
microbenchmark, but obviously that doesn't generalize to arbitrary code).

Let's take a moment here and wonder a "documentary team" in a country with the
kind of dictatorial control that North Korea has would have access to so much
American TV footage.
"Leaked"? You mean "released by the North Korean government"?

ChuckMcM
If you read the back story the translator believes exactly that, which is to
say that the DPRK created it for westerners. What is interesting is that the
website its on has completely bought into the message. They say things like
"And jesus, is it on the f&k*g money."
That suggests that it was targeted exactly to the sort of non-critical
thinker/reader that the site "superchief" represents, and by all indications
manages to hit on all of the sensitive spots. That is the point of propaganda,
and whether it is anti-Semitic white supremacist crap or DPRK crap it requires
that the person reading it check their assumptions at the door.

Dropbox: The hottest startup you've never heard of - slinky
http://tech.fortune.cnn.com/2011/03/16/cloud-computing-for-the-rest-of-us
======

I think this article is perfectly valid. What everyone here is forgetting is
that we are a pretty focused demographic of technical people. If you ask the
average CNN user what Dropbox is you'll probably get a blank stare. The fact
that an article like this is BEING written is just another sign of Dropbox's
success... it may be crossing the tipping point to main-stream media and
adoption outside of the tech community. I bet if you looked you would have
found something similar about Twitter at some point where social media savvy
people were going "WTF? I've used it forever"

I love Dropbox for not using this horrible term.
~~~
nbashaw
Horrible term? Just because it's the catch phrase du jour doesn't mean it's
totally meaningless. I get annoyed with the buzz and malapropism just as much
as the next guy, but like it or not, cloud computing is a major global
phenomenon.
~~~
iamdave
It IS a meaningless phrase in the sense that it's being used.
When I was studying network engineering, "the cloud" used to encompass the
broader network environment that INCLUDED the Internet as an extension of your
enterprise infrastructure. Now? It's a hyperbolic, singular phrase that is
limited to using the internet as an extension of your operating system without
fully explaining or at least detailing for the end user why it matters.
Especially in the case of those god.awful Microsoft commercials. In their
case, the way it's presented, the cloud is nothing less synonymous with social
networking. Change your Facebook status from Windows? That's the cloud. Upload
a picture to Flickr? That's the cloud. It's no better than that phase of 'web
2.0' that was nothing more than superficial design elements that included
shiny buttons, dropping vowels and slapping the term 'beta' on everything. The
web is cyclical and this is the latest cycle.
While that in and of itself isn't BAD per se, it's a phrase that's come
synonymous with "rockstar" and "ninja" when talking about hiring developers. A
total and complete non sequitur.
------
SwellJoe
I've been shocked at how often I see the Dropbox icon on friend's systems. I
no longer live in silicon valley, and so I am completely out of the echo
chamber (except what I read here at HN). These are not nerds, not techies, and
not people who follow TechCrunch. These are artists, musicians, old folks,
nomads, and all sorts of folks that just don't do technology. But, they get
Dropbox. Admittedly, my parents aren't using Dropbox, but my parents don't
read CNN.com, either, and I can't imagine what they would even use Dropbox
for. I can't even get them to use flickr for photos, despite buying them a
digital camera (my mom still uses a film camera when she travels because she's
afraid she'll lose or break the digital one).
If I could invest in Dropbox, I would. But, that wasn't always true. I met
Drew at a YC party before they had anything to show, and were still figuring
out the diffing/versioning problems, and all the underlying hard problems.
And, I came away thinking, "Well, that's been done before. A lot. And it never
went anywhere." I had even built a little web-based file manager and sharing
app as a RoR practice app, a couple weeks before. So, I thought I knew a
business that wouldn't go anywhere when I saw it. I thought highly of Drew,
but not much of the idea. I was obviously very wrong about the idea.
Anyway, my point is, Dropbox hasn't been something "you've never heard of" for
quite some time.

>> _"...And there's little to stop...Amazon (AMZN), with its own Amazon Web
Services, from making a greater push into Dropbox's territory...."_
Dropbox actually runs on AWS by using Amazon's S3 for storage. This is what
allowed them to get up and running quickly and cheaply without needing a lot
of venture funding.
I would not be surprised with Dropbox's continued growth, if they in the
future were to set up and manage their own data centers to avoid being
dependent on Amazon or anyone else's platform. This would be advantageous if
Amazon were to decide to compete directly with a similar product.
~~~
bradleyland
Someone questioned whether Dropbox could compete with Amazon at scale, but
decided to delete it. This is a really valid question. I recalled a while back
that Backblaze asked a similar question and came up with a really cool
solution.
[http://blog.backblaze.com/2009/09/01/petabytes-on-a-
budget-h...](http://blog.backblaze.com/2009/09/01/petabytes-on-a-budget-how-
to-build-cheap-cloud-storage/)
I see this as Dropbox's future. PaaS is good for getting started, but with
numbers like what's shown in that blog post, it's hard to argue that something
like S3 is really priced at commodity levels.
------

counterpoint: Dropbox is a great product, clever tech, insightful marketing
etc. Even the YC application was great. And I think there's a large market
(even its present size is more than enough to sate my own avarice), but... it
doesn't seem that it could become a truly _huge_ company (like Xerox, Google),
without launching a series of increasingly unrelated products. Though perhaps
that's true of many huge companies (e.g. Apple, Sony, HP - even Microsoft has
Office).
~~~
lemon_pie
possibly. that said, 100m in revenue 4 years after launch with a fairly
unbounded market (every consumer), looks like quite the promising start.

The mildest expression of profitability possible. Though I'm pretty sure
they're doing way better than >0.
From scanning many acquisitions, my feeling is of the order of $200 million.
Though I'm basing that mainly on business acquisition (e.g. by Oracle), so I
might be very off for consumer acquisitions (considering youtube, facebook,
twitter etc).

When we were trying to figure out if Dropbox would be a good sync tool for
Leanpub, Peter went in to a local coffee shop and asked a bunch of people if
they'd ever heard of Dropbox. All of the baristas and everyone else in their
20s had, and had accounts. About half of the people 30 or older had heard of
it, and most of them had accounts.
We were pretty impressed with the numbers, and we ended up going with Dropbox,
and we've never regretted it.

I love dropbox and we use it personally and for our company (we are paid
subscribers). But it seems to me that this space has fewer barriers to entry
than say Groupon. People argue that Groupon has little barriers to entry but
the fact is that it cost a lot to sell and get merchants on board. Dropbox is
a very unique and helpful product but what will stop the competition from
creating something similar and possibly better?

Now is maybe the really scary time for Dropbox - here come the "me too's"

Dropbox is awesome, I use it, I love it.
I had the same thought as SwellJoe around early 2008: That's been done, it
ain't gonna go anywhere big. Obviously failed prediction on my part.
So the question is, what made Dropbox successful? There are plenty of players
in this area (some of them are older than dropbox): box.net, mozy.com, Windows
Live mesh, backblaze.
Furthermore, techies can easily do backup to their own S3 account, but they
love Dropbox.
What's the success factors? YC? Being MIT graduates? The clever "Tell your
friends and get more space for free" email? The market is just HUGE?
I know that 1 of them is using Python. =)
------
orionlogic
I like Dropbox but i use it less often. What i am waiting for is the same
solution from Apple. Their cloud facility has been just finished and they will
probably offer similar service not later than this year. It might not start as
pure storage facility but will start by account and device activation from
cloud, iphoto & music backup and then after figuring out how this cloud thing
work will probably offer similar subscription fee based service. After all why
they still didn't buy Dropbox? Probably they are working on it.

Ask HN: Living as a hacker in the bay area. - dvcat
I will be moving to the bay area once I graduate in a few months. One of the big plus points for me to move to the bay area will be to try to interact and learn from a bunch of smart people by going to hacker dojos, user group meets and conferences (mainly in machine learning and other data related things). My day job will involve some travel (within the bay area) so I probably have to get a car. Keeping this in mind, can people comment on some good places where I should live, how much I can expect to pay each month in food, rent, utilities, insurance etc (I want to keep irrelevant expenses as low as possible just because I want to save some $$$ for a rainy day), things I should sign up for to get to know about hacker like events (apart from read HN)?<p>Thanks!
======
steventruong
Rent has gone up significantly in the past year or two. Especially in the city
(SF). If you're trying to keep expenses down, find as cheap as possible (while
livable) studio or room up with roommates. Otherwise rent can be quite
expensive if you never lived in this area. The best way you can see how much
rent costs for the conditions of the places is to just browse through
craigslist for a feel (it'll be better than any numbers I throw out here).
San Francisco: <http://sfbay.craigslist.org/sfc/apa/>
Peninsula which includes Silicon Valley:
<http://sfbay.craigslist.org/pen/apa/>
Best places to live are San Francisco or Palo Alto. If you can't afford
either, live in nearby cities. Mountain View is a great alternative to Palo
Alto that is more affordable.
Having said that, if you're willing to commute via public transit or by car,
it matters less. Just be aware rush hour can be brutal between SF and the
Valley.
There are a TON of events both in the valley and in SF. For language specific
events/meetups, most of the better ones are in the city i.e. python meetup,
php meetup, etc... For hacker mixers and various other speaking events, those
are more in the valley. There are usually some sort of event happening at
Microsoft and Google as well that you can look out for including GTUG at
Google.
The best way I find events outside of people sending me links or what not is
to join meetup groups via meetup.com, join the StartupDigest email list, join
Plancast and follow people/friends, and browse Eventbrite.
Once you're here, you'll be plugged into more private events and stuff as
well, that aren't found in the above.
Hope that helps.

Bringing improved PDF support to Google Chrome - jancona

> I wonder what impact this will have on scribd, at least the 'avoid pdf pain'

There's a way to answer that. What is their userbase like, and do they run
Chrome? If the primary browser is still IE (and it kind of seems to me like
'easing PDF pain' is incongruous with people who have total understanding and
control of their interaction with the internet) then scribd will be safe
for... how long did it IE6 last? Probably about that long.

There are plugins both in Chrome and FF where any PDF links automatically

loading. I just tried out this new integrated PDF on Chrome Dev channel

PDFs on the left hand corner, instead of center. Much much faster though.

------
616c
I am kind of disappointed that there is some baity qualities to this article,
specifically referencing how Linus chewed out a systemd developer. He did
that, but I recall it not being directly related to his work on systemd and it
negatively impacting the kernel. Kay Sievers is a well-known problem causer as
Linus is concerned, so this is not news.
Keep in mind if you find the mailing list thread referred to, Greg Hartmann
(gregkh), the release maintainer of the Linux kernel, arguably part of the
inner echelons, is responsible for the kdbus branch eventually getting merged
into the mainline kernel, that is the kernel driver that will internalize dbus
as a main (if not only) IPC of the kernel and reducing the overheard of using
dbus now (reducing 12 operations per dbus call to 3 inside the kdbus driver,
IIRC from Lennart's video). Again, this is the work of Lennart Poettering
pulseaudio fame, and now much more heated systemd fame. So to pretend the
Linux kernel is opposed systemd work is not truthful. Some core devs have
taken it on and are staking themselves on it. If this gregkh tidbit does not
make that obvious I do not know what does.
Can someone who knows more comment on what the substantive changes are thus
far? Is the kdbus work a prime motivator of this? I love systemd hate as much
as the next guy, but I was hoping we would get more facts from the HN crowd.
(EDIT: I know I will get downvoted, but I do use systemd and I am not its
biggest fan; I just used Arch and got used to it; everyone has a right to
choose their tools, and init systems ain't different.)

oxymoron
I'll concede that the analysis isn't completely without merit, but having
spent the last few years in ad tech, I sincerely hope that there won't be a
revival. It's a race to the bottom. Publishers are struggling and are
increasingly willing to accept ever more outrageous ad products. Advertisers
are desperate for advertising that actually works, but will mostly only do
what agencies tell them, and the agencies are only interested in maximizing
their own margins. In the middle we've got any number of middle men scrambling
for some pieces of the cake, sometimes but usually not providing some value,
leaving the publishers with a pathetic fraction of the advertiser spend.
So essentially we've got a whole bunch of companies with no growth desperately
vying for the attention of 23-year old media buyers who in turn are mostly
interested in getting someone to take them clothes shopping and picking up the
bill. These companies are doing it mostly by doing ever more intrusive things,
since advertisers can't accept that the reason their ads don't perform is that
nobody wants their stuff and keeps looking for a silver bullet.
I've come to believe that the only reasonable justification for most
advertising is that it's in some sense a way for other industries to subsidize
journalism. Since that's going away, I'm looking forward to the inevitable ad
tech carnage ahead, and if a potential next wave actually brings higher
quality advertising and better end user experiences I'll happily eat my shoes.

All of this, plus the vast amounts of bot traffic that no one wants to look
too closely at, because everyone except the advertiser is making money off of
it...
~~~
ec109685
Bot traffic is accounted for in the price advertisers pay for ads. Advertisers
don't run unprofitable ads.
~~~
simo7
Advertisers do run unprofitable ads and marketing campaigns all the times.
And they are fine with that too. That's the case of VC-backed startups: they
accept a negative ROI to get the chance to start making money one day.
Then you have the less consciuous ones, which might be big brands who want to
experiment a bit with new media/ad formats.
In any case, if you think about it, the real losers are...the honest
publishers. Because the money on the table is not increased by fraud, it's
just shared in a way that takes something away from good publishers to
bad/fake ones.
~~~
ec109685
I agree honest publishers are at a definite disadvantage. Advertisers aren't
because the roi calculation they come up with judges their campaigns based on
its performance, which incorporates good and bad clicks over time.

I don't see any mention of ad blockers. Are these seen as having a significant
effect on the online advertising industry? Are there any serious proposals to
deal with them other than continuing the ad-blocker-blocker-blocker... arms
race?
It seems that there's an increasing understanding among publishers that low-
quality and intrusive ads encourage their visitors to use ad blockers or
another site. Several relatively high-profile sites (like The New Yorker) have
stopped using networks like Outbrain and Taboola. (Obnoxious ads from the
latter, along with autoplaying video ads on numerous sites, resulted in me
finally installing an ad blocker after resisting for years.)
Adblock Plus offered a way forward with its "Acceptable Ads" program but it
seems like that has been roundly rejected by both advertisers and blocker
users. Maybe publishers and advertisers could work together to develop a
stricter set of advertising guidelines that show respect for users? I suppose
such a program is essentially doomed without cooperation from Google and
Facebook, and I don't know if they'd be willing to work with the little fish
(or each other).
It seems like an intractable problem. I'm not convinced technology (machine
learning! the solution to all problems!) is capable of providing the solution.
~~~
tomjen3
The problem is that most ads suck. Facebook knows more about me than I do, but
they can't come up with ads for things I want. What possible chance does a
random newspaper have?
~~~
pascalxus
I completely agree. 99.99% of the ads I see on facebook are for things I don't
want. They really need to get more AI and more information about the user for
better targeting. They may have world class targeting, but it still sucks
compared to advertisement that can read my mind (doesn't exist yet).
~~~
pdkl95
A common misconception is that targeting is about _your_ interests. An AI
won't select ads for things you want. Instead, it will use all of that
tracking data to select ads that are more effective at misleading you or
_changing_ your interests.
~~~
tomjen3
What is easiest? Sell me things that I already want but don't know about, or
changing my interests and then convince me to buy a particular product?
Incidentally 5 years after moving into an apartment I still need a good
curtain for the kitchen. If I see an ad for a place I can upload measurements
and get the results sent to me I would be very happy to pay.

_> The end of impressions and banners in favor of views and "publisher
rendered" (aka native) creative_
Native advertising, which I'd re-phrase as 'sponsored content' or 'content
placement', I can actually enjoy, if the sponsorship is made clear and the
topic is genuinely relevant to the audience. After all, who better to tell
what kinds of content readers want to see besides the publisher who puts it
out there? But it _has_ to fit -- out-of-place content will be painfully
obvious, and cause further user aversion for ads.
But the thing is: all of this can be accomplished without ad networks that
track your travels through the web. The client can engage the publisher
directly or through a broker. Where does that leave today's adtech?
~~~
andygates
That seems unduly optimistic. The content will be uploaded from the same old
terrible content farms, and be the same old rubbish only with a heavier local
server load.

Very interesting read, thanks OP! I've started using some platforms with
integrated ml, and it seems to be much better. Its difficult to get used to
starting a campaign, and instead of meticulously setting up targeting (males,
$50k income, denver, into football and skiing, etc) the ml lets you just ..
upload an ad and a web page. No targeting. Click GO and it will find your
customers. If Google or facebook can get into this space they'll succeed
greatly because they have so much data and users already trust them.
~~~
mars4rp
can you please name those platforms ???
~~~
soared
I'm at an agency and have access to some closed betas, but I've been pretty
impressed with StackAdapt for their native. They just added video and display
I believe but I haven't used them. You do a little bit of manual targeting but
their ml really does well.

White paper downloads for elderly people. For some reason their interface
underreports conversions though. But we've tied their traffic directly to
purchases! One note though.. like some other channels you're buying a mixed

make up for it.

keldaris
Since there's rarely any widely interpretable public data available, articles
like this and many others are my best gauge for noting that even the Internet
advertising industry itself recognizes that it's dying. This is very pleasant
to observe.
Personally, I can't remember the last ad I've seen while browsing. The
combination of AdBlock Origin (with a very generous combination of various
blocklists), Ghostery / Privacy Badger and NoScript effectively renders most
adtech useless. The few remnants that refuse to be blocked I happily skip
outright rather than enable. As far as I'm concerned, the only acceptable form
of advertising consists of things like hardware companies supplying free
samples to review sites without any preconditions and even there a slippery
slope exists, as evidenced by the sad state of the games "journalism"
industry, where corruption is endemic.
And the best part is that, unlike many political and social issues, users
really do have all the power here, and it's trivially easy to exercise it.
Install a few trusted browser extensions and you've helped hasten the demise
of a harmful parasite of an industry, and improved your own security at the
same time. And nowadays it's easy to persuade even non-technical users to do
this due to how disgusting and intrusive ads have become.
~~~

Congratulations! You are in the 10% of people who have adblock :) Within the
600B advertising industry. You get the point right? Normal people think
different. In addition, mobile is overtaking everything and adblocking there
is more tricky, thats why Facebook is generating 80%+ of their revenues via
mobile ads (fun fact, in 2010 it was 0%). You can ask your parents for
instance whether they know how to limit ad tracking.

I _feel_ like another piece missing from why these companies are "flat" year
over year is the fact that they are running into a wall of what people will
tolerate. I don't think that there will be a renaissance like the author
concludes. As a guy who worked in ad tech these tricks have been exhaustively
tried. I think right now the industry trend is to pay for premium content
rather then be inundated with Ads especially when it comes to games, video and
music. I imagine we will see this pattern continue especially with the mobile
gaming industry figuring out the key to everyone's wallet: in app purchases.

manigandham
This article is mostly bullshit.
AppNexus is one of the major SSPs (sell-side platforms) but they still have
major fraud and legacy tech issues. They are also one of the primary causes of
miserable user experiences across the web. They will not be part of any adtech
renaissance.
Google won't flinch if margins really do go down to single-digit margins.
They're already built for worse conditions than today and are just pacing the
market, as seen with the whole header bidding scenario. They also have Google
Cloud rapidly scaling and will likely be a bigger source of revenue than their
entire ads division in a few years.
Meanwhile AppNexus can barely survive on their current margins and will be out
of business if it hits single-digits. The disintermediation mentioned in this
article will also apply just as harshly to AppNexus.
The lame insights about machine learning and formats aren't anything special.
This is why Google and Facebook get all the money already, because they have a
much faster, cleaner, more relevant, and more effective ad experiences. The
renaissance is already here and it's getting increasingly harder to compete
with these data behemoths. It's not impossible though and there are several
niche focused ad startups, but there's no big sea change about to happen. This
is all just business as usual.

and what they do? Internet ad industry information is impossible to google
because it mostly turns up spam.....
~~~
wastedhours
I've tried to find a long form piece on it (ideally a physical book as
reference), but failed.
DSP: Demand Side Platform, is the tool agencies and advertisers use to buy the
ad spots automatically based on tracking profiles.
SSP: Supply Side Platform, is the tool publishers use to sell their ad spots
(publishers push an impression to an SSP, a DSP will evaluate it and an agency
will buy an ad on it - Google is main SSP and DSP [I think?] so people are
wary about them.)
DFP: DoubleClick for Publishers perhaps, as in, ad tech for media sites to
manage the display process (guess it could be called Google's SSP).
DBM: DoubleClick Bid Manager, is Google's DSP
ADX: guessing just an ad exchange, so a place advertisers and publishers do
the deal.
GDN: Google Display Network, posh AdSense where you can place your ads across
3rd party sites, not just the SERP.
Then we get into the world of Header Bidding (which, as far as I understand
it, is even more tech to bypass your usual SSP/DSP process to get the best
deal from different ad exchanges) and that whole murky world...
I've only been on the advertiser end, speccing a programmatic campaign through
a specialist agency. It makes me nervy as our only marketing attribution is
last touch and that rarely works with broad reach display. Retargeting is a
much more valuable one to explore.
If anyone would be interested in a guide, I can look to put one together with
definitions and a few anecdotes from some players? Username @ gmail.
~~~
ssharp
I think it's worth adding how DSPs and ADXs fit together. There are only a
handful of ad exchanges out there -- Google ADX, OpenX, AppNexus, etc. Some
brands and agencies are large enough to buy inventory directly through these
but for most brands and agencies, it's too expensive and cumbersome to do so.
This is where DSPs fit in. DSPs buy large batches of inventory from the ad
exchanges and resell them to brands and agencies and try to add value where
they can.
------
intrasight
I've come to believe that this isn't a technology problem. It's a people
problem - specifically a "publisher people are lazy" problem. That lazyness

I know it's not for everyone but I hope more publishers can work out a shift

Are your readers the sort of people advertisers want to connect with? Great!
Sell space and support to them. Or is your audience so diverse and ephemeral
that advertisers don't care? Move into publishing stuff that's useful to an
audience advertisers value, because when everyone else is slipping down the
ladder, it's a great time to try climbing it.

na85
>The internet needs an ad tech renaissance, one based on creating real value
for publishers and marketers,
Could not disagree more.
Advertising as a whole needs to die in ignominy. Obviously that'll never
happen, but we should be working towards ways to make advertising obsolete or
unprofitable, and we should be ostracizing people like the author who try to
or want to make things better for advertisers.
The promise of the internet was users as first-class citizens, not users as
mindless consumers of hostile advertising.
~~~
SerLava
Hostile advertising and advertising in general aren't the same thing.
I'd be the first to point out that advertising has motivated a wide array of
terrible things, especially in the last few years. But advertising at its
barest sense can be and usually is a net positive force.

To me, the second list comes off as more Mac themed. _Carbon_ is a set of Mac

nickname of the Power Mac G4.
As for the first list, OS X has a desktop picture of poppies and Expresso[sic]

This is amazing, I had never even connected the two points of data in such a
way as to realize that someone alive when Lincoln was president would still be
alive when TV is on the market.
Aside from the intense tobacco ads (the big banner and the participation
gift), I find it interesting that they were playing for the amount of $80.
Accounting for inflation, that's around $650 in today's dollars. Meanwhile
these days, game shows play for a top prize usually around $10k to $1mil per
episode. I guess in 1956, TV itself was enough to keep people entertained and
tuned in. I wonder if 50 years from now, they'll be playing for people's lives
or something equally crazy to keep jaded video audiences tuned in.
~~~
burgerbrain
Actually, there are still plenty of gameshows around where people play for
(generally) sub-thousand dollar prizes. Cash Cab
(<http://en.wikipedia.org/wiki/Cash_Cab>) comes to mind. $50 payouts on that
show are actually surprisingly common, although that is considered doing
poorly.
I suspect that the perception of the cash prize size is related to the
perceived commitment the contestant has to put forward. So they are fairly
large on shows the contestant has to go out of their way to be a part of, but
low on shows where the contestant just happens to "stumble upon" the contest.
~~~
JangoSteve
That's a very good point, and Cash Cab is sweet. Also, I was under the
impression that the people guessing in that gameshow were celebrities. Are
there any game-shows today that play for sub-thousand-dollar prizes with
celebrities?

I know this is what is referred to in Midnight in Paris as "Golden Age
Thinking," but I can't fight the feeling when I see television programs and
interviews in the 50s and 60s that the level of "popular" discourse was much
higher then than it is now. That is, interviewees of all ages are much more
well spoken, articulate, and informed. I can't imagine the panel of American
Idol judges (much less the audience) being able to drill down so quickly to a
historical event like that, or even care to take a serious crack at it. Am I
off?
Ex, a 60s era CBS documentary on rock--fair from and to both sides:

Did you notice the last word spoken by the host Garry Moore was "withal",
meaning "nevertheless". Can you imagine a game show host using the word today?
~~~
jerf
Yes. Or rather, the temporally-updated equivalent. Withal sounds erudite
because _now_ it's dead, and a sign of sophistication to know the word at all.
Much less so then, albeit perhaps not zero.
The problem with some modern game shows isn't vocabulary. It isn't even
necessarily spectacle _qua_ spectacle, because if they could have done it and
afforded it in the 50s their shows would have been bigger, too. Humans haven't
changed in the past 60 years. The problem with modern game shows is something
more like they have more resources than they know what to do with, competing
against ten other shows with the same "problem". I'm not convinced there's a
good argument for modern people being more relatively degenerate than people
of old... the set of which, I would remind you, _really does_ include actual,
factual people who considered combat to the death fit entertainment.

i'm currently reading _the master switch_ (<http://amzn.to/qvgGrx>) which
talks about how early radio and tv were forbidden to have commercials because
they were supposed to be public services, but that programs could be sponsored
like you see in the video. in early radio, companies weren't allowed to
directly mention their products, so for example, gillette's first radio ad was
a lecture on the history of beards.
after seeing that video, i much prefer commercials to that style of sponsored
programming. when a commercial comes on, you can get up and do something else,
change the channel, or mute it. with sponsored programs, everything is so

Wow, this is amazing. I can't help but want to ask him questions -- what was

Union troops make a lasting impact on DC? Did his family know people on both
sides of the war? Did he see any of the heroes from war later on in his life?
Attend a speech they made or a book-signing? Did he see Grant on any of his
famous carriage rides through the city? Know anybody who had personally spoken
with any of the presidents? (Back then you could just show up at the WH and
ask for an audience.) What did he think of the many civil war reunions and
joint parades that previous fighters from both sides participated in?
You know, there's a finite number of these questions, and they can be broken
down into an ontology and recorded. You could even make such and information

LLVM’s garbage collection facilities and SBCL’s generational GC - lispm

Great to see people acknowledge this. Garbage collection is full of tradeoffs;
be skeptical of any claims to the contrary.
I also like the way the author emphasizes the importance of inline bump
allocation in the nursery. In the fast path, allocation of memory doesn't need
to be any more than 5 or 6 instructions. This speed advantage is huge, and GC
schemes that throw it away need to have a _very_ good reason for doing so.

I have some experience writing garbage collectors and with the situations I
was targeting the handful of instructions quickly fades when multiple threads
come into the equation.
1\. Using atomics for bumping the pointer had some luck but contended atomics
on the platforms I was targeting meant that the low-instruction-count
allocation was still slow.
2\. Using locks (futex-style) was slow, as expected.
3\. The best results I found for my use case (precise garbage collector for a
runtime targeting video game consoles) resulted in per-thread nursery-type
allocation arenas, selected by TLS, with no locks in the fast-path. This was
slower than the ideal single-threaded fast path because of the TLS overhead.
~~~
pcwalton
Yeah, the canonical solution for multithreaded GC is the third option (TLABs).
The TLS overhead is annoying, but on some architectures you can get away with
burning a register to save the TLS load. It might well be worth it on AArch64,
with its 32 GPRs...
(TLABs are the recommended solution for multithreaded malloc implementations
like jemalloc and tcmalloc as well.)
~~~
cwzwarich
AArch64 has a dedicated register (TPIDR_EL0) for TLS.
~~~
pcwalton
Didn't know that, thanks!
------
eschew
At least two of the article's statements about LLVM are false. In particular:
1) LLVM doesn't place any restrictions on how a language runtime allocates
memory.
2) LLVM doesn't "expect" a stack map -- it provides infrastructure to compute
them if the front end wants to, but the front end is completely free to ignore
that infrastructure.
~~~
fao_
Are those corrections to the incorrect statements, or the incorrect statements
themselves? It's not very clear, I'm sorry.
~~~
sinistersnare
So I wouldnt say that LLVM places restrictions, but I will say a little of my
experience doing LLVM + BoehmGC
BoehmGC uses the stack for its root set (where it starts to find live memory).
With LLVM, you dont ever need to explicitly use the stack, you can use
registers for everything and make LLVM figure out if it should go on the stack
or not. If you want to use Boehm with LLVM, you are forced to explicitly
allocate everything on the stack, and not just on a register, so that Boehm is
guaranteed to find the memory.
So I wouldnt say restriction, but definitely you need to think about how LLVM
operates with the GC and other runtime components of your language.
------
twoodfin
I love the idea of a “liberal” GC that occasionally throws away bits of memory
still in use in the name of raw performance for restartable tasks.
~~~
johncolanduoni
How do you know when to restart the task? Or that your output isn’t the
product of an out of range memory access?
~~~
eslaught
You unmap the memory when you free it so that it causes a segfault if you
access it, and then if a segfault occurs you know something went wrong.
~~~
littlestymaar
> so that it causes a segfault if you access it
No, this is UB. It can cause a segfault, but it can also allow _bad things_ ™
to happen.
~~~
barrkel
Let's be clear on the difference between C and C++ undefined behaviour, and
machine behaviour that GCs and runtimes can use for implementation.
It is not unusual to rely on triggering a hardware exception in runtimes and
GCs, up to and including segfaults. For example, a check for safepoint might
be implemented by attempting to read a particular address. When the GC needs
to stop the world, it could change the protection bits on the page that
contains that address. This technique minimizes the amount of code in the
safepoint test and doesn't require any branching logic.
See e.g. [https://stackoverflow.com/questions/46394575/safepoints-
in-j...](https://stackoverflow.com/questions/46394575/safepoints-in-jvm)
Another technique: a runtime can support dynamic growth of the stack by
keeping an unmapped or protected page at the limit, and extending it when hit.
This is how stacks work on Windows, and it relies on help from codegen:
compilers targeting Windows need to generate code that performs a loop
touching every page in its stack frame allocation one at a time in allocation
order, if the stack frame is larger than the page size.
See e.g. [https://geidav.wordpress.com/tag/stack-
probing/](https://geidav.wordpress.com/tag/stack-probing/)

masklinn
> Another example where you want to keep for-GC bookkeeping overhead in

That's one of the common options in Erlang/Elixir: spawn a worker process for
each task with a `min_heap_size` high enough that most workloads would not
trigger a collection (the default is fairly low), let it die after it's
handled the request. More complex/memory intensive tasks will fall through to
normal GC-ing behaviour once they breach the `min_heap_size` limit.

Tarean

I have a basic understanding about card tables and promotion but couldn't find
anything about hole punching. Pretty sure I have heard the term before and was
just as confused, could someone point me into the right direction for this?
From context I'd guess that it means the gc doesn't copy unless x% of the
block is unused?
~~~
cracauer
I use the "punch holes" phrase in the following situation: \- GC is
copying/compacting \- GC is at least slightly conservative \- allocation is
fast/inline/increment-only \- that leaves you in a situation where you cannot
move/compact some part of the heap
You cannot move the possibly (conservatively) pointed to thing because you
cannot adjust the pointer to it (because it might be a non-pointer thing such
as an integer.
Now you have some GC unit worth of space occupied by one unmovable object,
otherwise it's empty space backed by physical pages. What do you do with the
rest of the space? In a C/malloc scheme you are aware of such holes and fill
them from new allocations. When you have a fast allocation scheme not
involving complex code to find holes you will keep these "hole" as long as the
conservative-pointer looking thing exists. You do wipe all the other
pointerish things in that GC area, though, so that they don't hold down
additional space. Still, now you "waste" a whole GC card worth of physical RAM
on a single object, the tradeoff being that you do not want to move to an
allocation scheme that spends time thinking about fragmentation.
You could use the empty space in those GC cards as a target for the next
moving GC, however that has drawbacks as you know continue to have to special-
treat such regular objects co-located with possibly conservatively pointed to
objects.
If there is a better term than "punching holes" for this I would be
interested.
ETA: now that I think about it, you could give back all physical pages in that
GC card that do not contain the held down object. This assumes that GC card
size is more than one VM page.

(author here) Just wanted to say that I have seen the comments and will

than I anticipated and I was busy yesterday and today. I wrote most of this in
summer 2017, so given the popularity I will also provide a refresh with
today's state of LLVM.
Please keep corrections to my post coming, the time to determine and influence
GC design restrictions in LLVM is now. Before a popular GCed language comes
along and then tramples whatever its current GC happens to be into the status
quo.

Among the bleeding edge tech community, Deezer and Spotify are considered the

Yep - the thing about these numbers are that they're obviously based on
_registered_ users, not active users. For example, which Spotify may have 33
million users, only 20 million of those are active. Pandora may have an
impressive 150 million registered users, but I imagine the drop off rate of
active users is relatively high given the increase in popularity of other
services.

yeah, and with these streaming services there's also free vs paid users.
And Pandora is not profitable. I believe Pandora loses money with each user-

Fantastic article. We need more deconstruction of "fads" (which I don't mean
in a pejorative sense) so that we can quickly understand them without
sacrificing tens of thousands of man-hours slowly coming to terms with each
one. It would be much better if we could reason about the exact differences
and benefits instead of getting bogged down in new terminology, etc.
More examples I've been thinking about:
\- Goroutines (fibers are equivalent to threads, but coroutines are different)
\- Safety and the unsafe keyword in Rust (not sure but the effective
difference seems to be default-allow versus default-deny)
~~~
pjmlp
Regarding those two examples, more than having explanations about them, it
would help if people cared about IT history and it was more accessible.
Coroutines are easily explained in Modula-2 literature.
Safe keyword in Rust goes back at very least to Ada and Modula-2. Also in
Oberon and its derivatives, Modula-3 (which inspired C#). The literature for
those systems also has lots of examples.
Being an old IT dog, that started when those technologies were new it is
sometimes hard to me to see how new generations fail to find such information,
even though it is available on the web. I guess the main cause is thatbone
needs to know what to search for.
~~~
pjc50
Tech is strangely ahistorical. Not just practitioners not reading the
literature, but it seemingly being forgotten entirely. Possibly this is a side
effect of so many of us being self-taught.

DOOM code should have been thread-safe.

wslh
I would say cyclical. Every day we read about a similar framework working in a
popular language when that solution already existed for long time.
But this happens in other areas outside computer science. For example, modern
medicine rediscovering old medicine "recipes".
The problem in our field is when people talk all day about Docker while
surpressing LXC from the discussion.
~~~
digi_owl
I think it happens for different reasons though.
With medicine it boils down to a dismissal of folk remedies as placebo.
But with computing its because the old ways were developed on mainframes and
minicomputers in an environment that current generation may only have heard
stories about.
This because the micro-computer era was pretty much a mental reboot for
computing, as little if any software crossed over (until fairly recently).

I am surprised nobody mentionned nix, nixos and guix.

~~~
davexunit
Nix and Guix are purely functional package managers, meaning that software
builds are treated like a mathematical function: Input the same source code +
dependencies and receive the same build as output. They have features such as
reproducibile (often bit identical) builds, transactional package upgrades and
rollbacks, and unprivileged package management. They solve the dynamic linking
problem by allowing each package to refer _precisely_ to the dependencies that
it was built with. With this mechanism in place, it becomes very easy to use
applications that require different versions of some C library, or a different
Ruby/Python interpreter, or whatever else. Furthermore, it can do this without
relying on a specific type of file system, and without requiring that
applications be run inside containers or virtual machines. This makes it very
composable and general-purpose.

The official images aren't fixed in time, assuming you're pulling using a tag
e.g redis:3.0. That image may be updated at any point and should be updated
with minor patches and security updates. Rather than manually apply patches,
just pull the image again to get the updates. If the image hasn't been
updated, complain loudly.
If you want your image to be "fixed in time", pull by digest instead.

Very interesting. I'm not convinced this captures the core value of containers
though. Or at least not the only core value. Calling containers an evolution
of configuration management tools seems like an oversimplification just to
make a point. This may be one aspect of building a micro-service driven
architecture that containers make easier, but there are other very important
ones. Portability comes to mind. It's not just that you can build your stack
once and save it, but that you can then run that stack anywhere, and it
becomes much easier to share/borrow bits and pieces of other people's stacks.

To a certain degree I don't _want_ to know what's in them. If I want to add

Shared libraries were considered a bad idea in Plan 9, and I really wish that
point of view had made it into commercial Unix and Linux.

Shared libraries are a fantastic idea. Static linking wastes system resources
and makes system-wide library updates problematic. Docker's approach to things
is essentially a higher level form of static linking, which is to say that
it's not a very good approach. It's papering over the package management
problem. We need general-purpose package management systems that allow for
different applications to use different versions of shared libraries without
interference. Luckily, the Nix and GNU Guix projects solve this problem very
well, if only they could get some more "mindshare."

Ideally, I want no dependencies between container and host, or container and
container. Or at least I want them kept to an absolute minimum.
Even more ideally, I want isolation to be so complete that I'd be able to run
my built stack 100 years from now and have it operate exactly the same as it
does today. That's a bit hyperbolic, of course.
Docker is not a linker; it is a system from which you build deployable code.
In fact, there's no reason why in theory you couldn't add support to deploy
Windows or BSD stacks (other than the fact that Windows and BSD kernels
haven't been added yet).
------
BurritoAlPastor
This is an interesting take, but it doesn't entirely make sense. Ierymenko's
'save your work' metaphor is a little misleading, since (I certainly hope)
nobody is creating docker images manually. But I like his idea that dockerfile
creation, by which you set up a stack in a way that's automatically
reproducible, is equivalent to the role of a linker in a compiled program.
Where he loses me is when he suggests that Puppet et al are closer to a 'pure'
linker. Configuration management systems are doing the _same thing_ as a
Dockerfile: instead of setting up your XYZ stack by hand, you write a Puppet
manifest that calls the modules for XYZ and sets them up the way you need.
Your final result isn't a server with the XYZ stack: it's an _abstracted
process_ that will _reproduce_ your XYZ stack. The main difference is the
implementation; Docker reproduces your stack in an isolated environment, and
configuration management tools reproduce your stack on an arbitrary platform.
But nobody thinks of Docker as a configuration management tool, and for the
most part I don't think people even think of Docker as a _competitor_ to
configuration management. Hell, Docker is a core component of many Puppet CI
workflows.
So there's something else going on here. What's the secret sauce? Is Docker
just two great things (config management + virtualization) glued together so
cohesively that it becomes greater than the sum of its parts?

That's a very clever metaphor for that aspect of Docker. I hadn't considered

According to this article, Docker is a way to save your work after configuring
your server. Can't I do that with
rsync -a /etc /whatever backupserver:/backups/server1
?
~~~
fragmede
First off,
rsync -a / backupserver:/backups/server1
would be a better comparison; full server state never properly stays in /etc.
Do you actually do that though? Multiple times a day? How easy is it to roll
back to a previous state?
Given Dockerfiles, a better comparison would be rsnapshot, since intermediate
steps are important, and maybe that last "yum upgrade/apt-get update/whatever"
broke something (on dev, of course) and you want to roll back.
How do you compare two related file system images? Is there something more
advanced than "diff -u"? How does that handle binaries? Will that map
backwards and say what command resulted in changed binaries? Can I submit a
code review for the changes between the two states like I could for a
Dockerfile which is plain text?
Docker isn't quite a configuration management system like Chef or Puppet, but
there's a lot of overlap.

It's more impressive when companies add people to their board who add a
perspective other than the entrenched (dare I say evil) mindset of their
competition. An example: Chipotle adding Bill Niman, an advocate against
factory farming, fast food and cheap meat. A good move for Groupon would be to

Do you need your system to be transaction-oriented (think ATMs and banking) or
analytic (for doing slice and dice reporting of data)? You'll do well to check
out normalization for the first and understand star schemas for the second.
It's awesome you are thinking about db design upfront, just think about what
your data will be, how it will be used, and how you will want to move it
around for your app. Don't discount not using a db at all (and I'm a db guy
for work) - for one of my current projects, I'm simply dumping small data
objects into individual JSON files. Easy to fetch with Ruby/Sinatra and easy
for the GUI part of the app to play with (Javascript eats up JSON on that
side). Not to discount Rails at all, but going with a minimal toolset like
Ruby/Sinatra/Sequel might be just the ticket for you roll simple web apps
really quickly.
Heck, this forum uses flat files for storing submissions, comments, and user
data.
~~~
bgnm2000
Thanks for the reply!
I'd say the data is definitely going to be analytical - but some parts will be
transaction oriented, if that makes sense (people will be able to pay for
greater functionality).
I don't think I know enough about flat file systems to code one up myself at
this point either (not that I know enough about DB's - but enough to create
something).
Any good resources for understanding star schemas?

tom_b
Sure, grab one of the data warehouse books from Kimball. Inmon is the other
big data warehouse author out there, but I'm not as familiar with his texts.
Kimball's stuff is an easy read and not platform focused in any way.
If you are aiming to do business visualizations with the data, you might want
to check out Stephen Few - he's written several books on business data
visualization (think Tufte distilled for charts and dashboards).

Does anyone have any good devil's advocate information on Facebook?
\- The company does not seem to have an appropriate ethics board (for the size
of company). There is some mention of an 'ethics AI board' but no real
governance over Ethical conduct and compliance. If there are internal review
boards
([https://www.theguardian.com/technology/2016/jun/17/facebook-...](https://www.theguardian.com/technology/2016/jun/17/facebook-
ethics-but-is-it-ethical)), then it appears that they are thoroughly
compromised, and not providing a level of accountability or serious thought
that anyone will take seriously.
\- There seems to be no intention or effort in achieving ISO standards (apart
from a single ISO:27001 certification for FB Workplace, which was arguably to
provide a 'feature' for the application rather than any ethical move).
Granted, the value of standards and frameworks will always be in dispute, but
these exist for a reason and are a neat 'package' that organizations use to
ensure they are not reinventing the wheel and acknowledging a list of
considerations.
\- Facebook do not seem to maintain an ethics page.
\- They do not seem to have an ethical voice - Nor do they appear to have
anyone even pretending to have an ethical voice. PR from facebook (usually)
manifests as 'We do what we do, and it's fine' rather than 'we will be
introspective about this'. It seems strange that there isn't even any
posturing here.
\- The two types of FB employee that seem to voice insight on public forums
are either a) discontent and being ignored by management or b) drinking the
koolaid and refusing to admit that their practice is unethical.
Ignoring Occam's razor for a moment - Surely there is something to cling on to
here, to provide the principle of charity for Facebook. FB sure are making it
hard for consumers to paint them in any reasonable light.

I'm sure the irony of reading these sorts of blog posts isn't lost on you all.
However, I do believe that some of these strategies and techniques can
actually work. I even wrote about it on the post 'how to make time for your
side-project'.
The key is not _just_ to break things down and to create tiny, regular
actions. It's also to _start_. Most of us like to talk and talk and not
actually do anything at all.
This procrastination and hyperbolic discounting means that we often go for the
quick fix rather than the ongoing journey to success. Starting and overcoming
our own psychology is often the hardest part.

Personally, I've found that the process of breaking down a task and writing it
down is incredibly useful. As I multitask throughout the day I forget where I
am in a particular task item, and having a list of things I'm supposed to do
all I need to do is go to the next list item and do that.
I also try to have high-level items for the day so that I know what I'm
focusing on. Anything that I need to do but can't do today I put on a list for
the next day.
It seems to be working out alright for me.
I currently just throw it all into OneNote, although it's not the greatest for
dealing with lists the way I use it, but the freeform writing surface and
search it provides makes up for it.

_I forget where I am in a particular task item_
Forgetting is my number one problem right now. I also noticed there's some
kind of unconscious filtering going on in your mind. Even if you write down
the tasks your mind prioritizes them on its own.
What I wish list software had was a way to push those less important tasks in
the background.
~~~
bentcorner
Be religious about writing down what you're doing, make a habit of referring
to this list when you find that you're bouncing around from task to task.
Sometimes I'll hit HN if I'm waiting for something to finish, and if I was in
the middle of something complex I've needed to write down what I was doing,
even if it was only for _literally_ a minute.
Also, when incrementally learning something it can help. Writing down in your
own words how something works can help you if you only have small chunks of
time to learn something.

I have always struggled with automating my life habits.
It's not that I don't have goals, I have them in plenty. I have problems with
the dehumanizing, machine-like feeling it puts on life.
Doing the same thing everyday at the same time sounds horrible. I don't want
to program myself. I want to live my life according to how I feel at the
moment.
But, as you can imagine, this has created problems. You don't keep jobs by
living for the moment or doing what you feel like doing.
I am not sure if I have a point, but I think there is more to life than
becoming a programmable robot.
Maybe balance is the key. Have good habits, but try to build some flexibility
into them.

Good article.
Ben Franklin's schedule shot was interesting. 8-6 workday with a two hour
lunch (so 8 hours of work). For some reason I always assumed people toiled
very long hours back in those day.
~~~
bhousel
Most people _did_ toil very long hours back then, but Franklin was one of the
first to make the jump from common class into pseudo-nobility. Class mobility
was a new thing back then.
The idea of "work" was considered very uncool at the time, especially to upper
class, or social climbers like Franklin who mixed with them. I heard somewhere
that this is why old school scientific publications have names like
"Observations concerning the Increase of Mankind, Peopling of Countries, &c."
Because we're not _working_ , we're just _observing_.
~~~
josephjrobison
A few counterpoints:
"These images are backward projections of modern work patterns. And they are
false. Before capitalism, most people did not work very long hours at all. The
tempo of life was slow, even leisurely; the pace of work relaxed. Our
ancestors may not have been rich, but they had an abundance of leisure. When
capitalism raised their incomes, it also took away their time. Indeed, there
is good reason to believe that working hours in the mid-nineteenth century
constitute the most prodigious work effort in the entire history of
humankind."[1]
But also:
"Based on the amount of work performed — for example, crops raised per worker
— Carr (1992) concludes that in the seventeenth-century Chesapeake region,
“for at least six months of the year, an eight to ten-hour day of hard labor
was necessary.” This does not account for other required tasks, which probably
took about three hours per day. This workday was considerably longer than for
English laborers, who at the time probably averaged closer to six hours of
heavy labor each day."[2]

derekp7
There's been posts about daily habits of other accomplished persons (not
necessarily programmers), and the conclusion from that discussion was that
although these techniques work for them, they would not really apply in
general. For example, some would have a glass of wine before starting work on
a project, whereas that would put me to sleep. Some athletes eat a big steak
dinner before a game, while with others it would hamper their performance.
My take on it, is that people that are good at what they do are good because
they are good, not because of any rituals.

12 things I learned from pitching VCs this past week - scrollinondubs
http://www.scrollinondubs.com/2007/12/12/lessons-from-vc-pitches/
======
dhouston
good stuff. sam altman told us the most important thing for him was to
remember #8 -- they need you as much as you need them. they _want_ to believe
that you're the next google; think of how much it would make their lives
easier if you were, and think of how hard it would be to spend your life
saying no 90+% of the time and telling people their babies are ugly. they want
to say yes.
i'd also say spend a lot of time coming up with a story and framing your
opportunity in the biggest possible way. this was something i really
underestimated -- initially we'd just show a list of features and expect
everyone to arrive at the vision we had in our heads, but really it's the
other way around -- the features drive a more important story and vision.
a story is also a lot easier for an investor to retell and get other people
excited about than a laundry list of "um, it does this, and this, and this..."
remember, VCs have to then turn around and sell their own general partnership
on the idea, so give them the ammo they need to do this effectively.
also -- practice your pitch until it becomes mechanical. not so much by
standing in front of a mirror (though that helps too) but rather by debugging
it with individual angels or mentors, so that by the time you pitch the
investors you really want you've already seen most of the universe of possible
objections and surprises and can handle them effectively.
~~~
scrollinondubs
dhouston- good call on having a big story. The VC's could literally care less
about the features of your product, they want to know how it's going to be
thing that will be a common-place word in 4 yrs and you have to paint that
picture vividly for them.
I would disagree on the pitching in front of a mirror thing. And actually i
should add this as #14- I recommend that you _don't_ have a scripted pitch.
Have a deck of slides that serves as a framework for the conversation but just
talk about it naturally. If you truly believe in it, this should become second
nature and they'll smell the candidness whereas a scripted pitch comes off as
brittle and less engaging. You want it to be anything but mechanical IMHO.

scrollinondubs
sure, in generic terms. Our lawyer was instrumental in getting 3 - we splurged
a bit and hired a very reputable firm in Palo Alto that is well-connected. We
paid more than we would have liked for the legal work a year ago but it's
paying dividends now in terms of introductions. The other intros came from
just random networking. We live in AZ but I drove my truck up to SF and couch
surfed the past month just going to events, shaking hands and meeting people.
I had a list of people I know through various user group involvement and
presence on listserv's so i contacted them and tried to have a different lunch
lined up everyday. I used Meetup, Upcoming and googled "Bay Area User Groups"
and tried to lineup a different event every night. I actively used Facebook
and my blog to solicit intros and tell people what I was doing, switching my
network to Silicon Valley temporarily and finding events via that. I met great
contacts at the Startup Weekend that was held in SF. And the whole time I was
writing a series of posts on my trip essentially live-blogging it to meet more
contacts. You can read those here if you're interested->
<http://www.scrollinondubs.com/tags/sfroadtrip>
There is no "typical intro" to describe - they happened in the most
unpredictable/serendipitous ways, but having the conversation-starter of "so I
drove here from Phoenix and have been sleeping on friends couches so i can be
in the mix for our startup" was a powerful lead-in to be able to talk with
people and get them to listen.
I know PG is a big fan of the idea you should really be in the Bay Area to
give your startup the best chance of success. We have our company in AZ right
now and moving wasn't an option so this was the next best thing we figured we
could do. Definitely very happy with the choice.

The wifey can complain when she is driving her new Bentley.
Sometimes business has to come before pleasure, I know my lady would wait in
the parking lot for 3 days if she knew it was important.
But if I was a VC, I would give everyone X amount of time, but have a plan B
to talk all day if things went well.
~~~
davidw
It would have cost him nothing (and he's the one with the money, in any case)
to say "hey, I'm running late, it's important, it'll be a while longer" rather
than simply not answering, as the article seems to say.
~~~
downer
Ah, but interrupting business for personal _looks bad_ ; and the thing about
(possibly most) women is they _want_ you to have something that's more
important than them. If you drop everything for them they won't respect you.
So he did the right thing from both perspectives. Which is probably why he's
rich and has a (presumably) hot wife.
(I know that sounds politically incorrect, but alas, reality often is. To be
fair, it probably works both ways: a man won't respect a woman who drops
everything for _him_ , either.)
~~~
davidw
I have a hot Italian wife, and would never leave her stewing like that.
It's not about dropping everything for the other person - I don't think anyone
can expect that. It's about picking up the phone and saying "sorry, got to
keep you waiting, it's important". Communicating and managing expectations.
It's a pretty minor quibble, I guess, but it just struck me as something rude.
~~~
scrollinondubs
guys, lemme clarify this- when i said "deferring calls from his wife," he was
politely saying "honey, gimme 15 more min" because he was so into it. It
really wasn't rude at all and perhaps I should have better explained it or
left that out altogether.

Show HN: Bon – programming language designed for simplicity, performance, safety - FBMachine

ngcc_hk
Have a quick look. Quite easy to read. Just not sure does it have an advantage
over swift which seems quite easy to read, cross 2 platform at least (linux
and macOS, the windows seems not on equal footing and five code not working),
target llvm.
The basic features of a new language is hard as you can see the posting what
expected. Macro (may not be lisp level but template), memory Managrment,
purpose (embedded, os, driver and application, ai library, CUDA, mobile app
etc.), library, platform, examples and q&a under stackoverflow etc.
... wonder what is the point of learning a new one.
------
ubertaco
This is really neat!
I'm a big fan of Crystal-lang, and I dig the similarity in the sense of "let's
start with Ruby-like syntax, and add more static structure". I can see the
difference here as being that Bon appears to _behave_ more like Haskell or
OCaml rather than like Ruby, which means that there's still a good niche here.
I hope this neat language finds success!

FBMachine
Thanks, I really appreciate it!

How is memory managed? I'm assuming some form of garbage collection. So this
can be used in any instance C or C++ can? Can it use C and C++ libraries
because it runs on clang?
Sorry if these are n00b questions. Bon seems like it could be a nice mix of
the wonderful syntax of a python or ruby, and the speed of a C or C++ (or at
least a compiled language)
~~~
FBMachine
Hi Chris, thanks for checking it out. The first code push for Bon was today,
so many things are of course rough around the edges.
Memory will be garbage collected, though I am aiming for zero-cost as much as
possible. At the moment it just leaks memory like a sieve as I work out the
semantics.
You can indeed import standard c library calls by using a cdef. You can find
examples in the stdlib, e.g.:
cdef sqrt(x:float) -> float
Thanks again for taking a look!
~~~
bendmorris
What is "zero-cost" garbage collection?
~~~
swiftcoder
I've seen both Rust's lifetimes/borrow-checker and Objective-C/Swift's
automatic reference counting described as "zero cost" (since the bulk of the
work is done at compile time).
~~~
m0th87
Rust's borrow checker is zero-cost because it's not doing runtime analysis.
But it's not a garbage collector, unless you're using Steve Klabnik's "static
garbage collector" terminology [1]. Reference counting is definitely not zero
cost. It reduces GC runtime latency for most workloads, but not to zero, and
it does so at the cost of reduced bandwidth.

orthoxerox
Having an stdlib, having a dependency manager and overall stability.

giancarlostoro
Yeah Rust and Go (and D) all have: decent standard libraries (Go exceeds the
other two, somewhat resembling Python), a package manager of sorts (Go needsa
improve in this aspect, but the strong standard library makes up for it for
now, and they are working on it atm), and they're all usually stable.
I think the biggest game changers for any new language is a highly competitive
standard library out of the box: web server of sorts that can somewhat scale
out of the box is usually a must, but at least a simple enough one is ok too,
file IO, crypto, etc are also useful, the less code I have to write the more
productive I feel.
Package management is a must too, even if primitive at first (Go's approach is
clean and decentralized to some degree, I love that).
------
charlesetc
It seems a bit premature to claim high performance without having a story for
memory. I'm sure ocaml, swift, and basically all languages that do any type of
runtime garbage collection would be significantly faster without it.
~~~
bunderbunder
It's complicated. The best runtime GC nowadays tends to take on some of the
performance characteristics of a stack, including that finding a new memory
slot is O(1). Heap allocation in many non-GC languages, by contrast, ends up
involving some sort of relatively gross search for free memory. The same
mechanisms also mean that, if you aren't doing anything in particular to
manage your memory layout, the GC language is likely to achieve better
locality of reference at run time.
This isn't to say that better performance isn't achievable in languages with
manual memory management, but doing so often requires a special effort that
just isn't going to happen most the time, for reasons of practicality.
That said, there are certain classes of program where the story is different:
[https://en.wikipedia.org/wiki/The_Computer_Language_Benchmar...](https://en.wikipedia.org/wiki/The_Computer_Language_Benchmarks_Game#Benchmark_programs)
~~~
zokier
I think the point was that you can make memory allocation _very fast_ if you
do not care about ever freeing memory, but obviously that is not exactly
sustainable strategy. So that is why making claims about performance before
figuring out memory management story is bit premature.

I'm curious about scoping. How come `main` in the typeclass.bon example gets
to call `norm()` unqualified? Do all the functions in all `impl` definitions
just get tossed in one global namespace? If `Norm` is a class, then why are
there no `Norm` objects?
~~~
perfunctory
This seems to be straight from Haskell. `class` here doesn't mean what it
means in oop languages.
~~~
FBMachine
Yeah, 'class' in Bon defines a typeclass. While I plan on adding x.norm() as
syntactic sugar for norm(x), typeclasses in general are a bit more flexible.
For example, while you can use it for polymorphic operator overloading [0],
you can also overload a function by changing the types of multiple parameters
[1] (as in multiple dispatch).

I would love if there was a language combining the strengths of Julia and
Swift.
Swift has: much nicer handling of optional values, static typing, better for
OOP, function calls via dot notation, zero-based indexing.
Julia has: better ecosystem for scientific computing, the standard library
makes lot of things easier, better REPL, working with arrays is easier.
(Just from the top of my head, there are other things.)
------
tropo
This is a terrible name conflict.
Bon, along with New B, was an immediate ancestor to C. The history gets more
confusing with another Bon showing up half a century later.
Bon was created for Multics by Ken Thompson. His wife Bonnie, like this other
person's mother, was the inspiration for the name.
Ken Thompson has naming priority.
~~~
chrislopez
Ken Thompson is a person, plain and simple. He is not a god. Naming priority
doesn't matter when most programmers haven't heard of old Bon. No one is going
to think that new Bon is old Bon if no one knows about old Bon. Maybe there
will confusion looking at the history if new Bon takes off, but when is there
not in computer science? A simple footnote could suffice to avoid confusion.

Looks nicely designed, but are lists really implemented as linked lists?
That's surely going to be very slow.

FBMachine
Thanks for checking it out. They are currently implemented similarly to OCaml,
so yes they are linked lists.
This was purely for simplicity (they can be implemented in a couple of lines
of code with algebraic data types). Simplicity of implementation is certainly
not my priority, just a short term drive, so it will be revisited in the near
future.
Thanks!

Americans Are Receiving Unordered Parcels from E-Criminals - monsieurpng

I had an interesting experience recently. I ordered a cheap $20 multimeter
from Amazon (which was highly rated on EEVblog), which was shipped from China.
Interestingly, the Chinese seller shipped me a single little worthless plastic
packet of heat-shrink remote control covers (which somewhat humorously I can
imagine totally being a thing in Asia, heat-shrink-wrapping all the remotes in
plastic, sort of like a couch in plastic). This was what the tracking number
package was for, and so I _immediately_ hit my bookmark to chat with an Amazon
rep to report fraud. I went through all the motions, they refunded me the
amount, I left a negative review. But then that night, I got an email from the
seller saying "That was your free gift, the multimeter should be there soon"
and indeed, the actual multimeter showed up _the next day_ , albeit with
another tracking number. The multimeter was definitely shipped from China the
same as the garbage package (via epacket, the subsidized, dirt cheap,
glacially slow shipping method), so the seller had to have shipped the stupid
garbage package at around the same time as the actual product I ordered. Other
reviews mentioned the exact same thing ("They sent me garbage, but I got the
thing in another package").
I've spent time thinking about what kind of fraud they're committing, because
it doesn't make sense to me why they would send the garbage package with the
tracking number from my order -- which _screams_ fraud -- but then _also_ send
me the _actual_ thing I ordered. They're sending two packages to the same
address, but it doesn't make sense why, since they're obviously not committing
the most straightforward kind of fraud ("We shipped the item, you can see the
tracking number", which incidentally, only works on eBay and not Amazon).
~~~
ggm
Well.. this story directly provides an answer (potentially) -they get an
additional marginal ranking benefit inside some market appraisal score because
they double their international successful completion count, for low marginal
cost of posting negligible weight content to you successfully. The benefit to
them is fraud, but not against you: its against the ranking engine inside some
digital marketplace like alibaba. You are an unrelated third party who
validates (by accepting) delivery. Since you don't know if the package is
shrinkwrap "free gift" or the $20 meter, you accept. Are you willing to monty-
hall reject the random package :-)
~~~
pyoung
So if I understand this right, they are creating a fake account on some other
site (aliexpress, etc...) with his address attached. And then they ship the
'gift' from the Amazon tracking number, so that he is more likely to accept
that package, and then ship the multimeter from the fake account tracking
number, allowing them to leave themselves a positive review on that site.
I always suspected something was going on with the aliexpress ratings. If you
look at the reviews it is a lot of one liners like 'i got the item as
described!' with a 5 star rating.
~~~
leggomylibro
This is the most convoluted thing I've had to think through in awhile.
Jeez. Honestly, I mostly ignore reviews on Chinese listing sites unless
they're low. It's all about two things:
1\. Is the price in line with other listings? From both directions?
2\. How many people have ordered it in the past 90 days?
Sometimes that does mean taking a risk with specialty items, or foregoing
them. But hey, if it's a critical application I'm not going to source it from
sketchy international cheap-o listings.

I wonder why we have the USPS Chinese subsidy? [1] Seems this makes the
shipping fraud too easy as it is low cost.
_It was a small epacket -- a special subsidized shipping option that the USPS
offers Chinese merchants, effectively enabling them to ship a parcel from
China to the U.S. for less than it costs to send that same parcel
domestically_
_Due to the unbalanced pricing policies of the United Postal Union and
subsidies from the U.S. Postal Service, it costs people in China virtually
nothing to ship small packages to the U.S._

I think a better solution would be to lower the outrageous prices charged by
the USPS to us.
If you want to send a 1oz 'package' to, for example, France, it will cost
$13.50. It used to cost closer to $3.40, and then they doubled it overnight to
$7, and now it is freakishly high.
Why is this? Because the USPS has a monopoly and is allowed to rob us!

If I wanted to send one to Canada, it would cost $2.29 for postage (because is
it a 'flat', so it is cheaper. If it was bulkier, it would cost $9.50).

It's the free shipping subsidy that's the underlying cause. It's the same

evincarofautumn
I don’t know if this’d work at all, but I’ve idly considered the possibility
of starting a grassroots “return to sender” campaign for junk mail.
As it is, the postal service is paid to deliver all of that spam—but maybe it
would no longer be cost-effective if everyone just said “nope, send it back”
whenever possible. As it is, I just recycle all of it, but it still probably
represents a sizable environmental impact in terms of materials, printing,
delivery, recycling, and landfills, which we could entirely do away with.

When a newspaper prints '{statement}, according to {source}' there's a reason:
they don't independently verify those facts. They're printing it in the hope
that it's useful, and giving you their source as a cop out or, if you're being
charitable, so that you can decide whether you want to believe it or not.
The statement "In 2012, USPS was paid only 94 cents on average for each piece
of Chinese ePacket mail, according to a February report from the Postal
Service’s inspector general’s office." is probably 100% accurate, in the same
sense that "Rahim is the best dad ever, according to his son" is true, could
be 100% accurate. You could stand by either statement. And both could be
accurate. But it doesn't mean they're not misleading (in that the fact being
discussed might not be true).
If you look for it, you'll see similar patterns scattered all over newspapers.
One of the most common examples: '{company} reported 4th quarter earnings of
{amount}'. There's a reason they don't simply say ''{company} earned {amount}
in Q4'.

Dumb question: Why are the vendors bothering to send anything?
~~~
nerdponx
So Alibaba doesn't figure out that it's fraud, probably.
~~~
captaindiego
Exactly. Often the shipping weight will be measured as it is shipped (likely
because most of these are coming by air). Alibaba and others pass this
shipping information on to the customer and would likely notice overly low
shipping weights.
Fraudulent sellers will also use a similar method in certain countries where
the delivery address is not tracked but weight and delivery status are. They
can send a nonsense package to the right country/state, have it appear in
China post tracking as delivered, but the fake package was actually went to a
random address with a roughly expected weight. If customers try to file claims
on sites like aliexpress they'll likely rule in the favor of the seller unless
you can somehow get your local post office to provide proof it was never
delivered to your specific address.

FiatLuxDave
It seems to me that the big issue with the SV venture model is the geographic
limitation of its current implementation. The reason that there is too much
money chasing too few deals is that the money is 'stuck' in certain places
(SF, NY, Boston, Austin). The assumption is that if you want to play the VC
game, you go where the money is. But not all good opportunities are in those
locations or are capable of moving there. And that is why we have mad
inflation in the money centers, while the rest of the country is living with
deflation.
I'm waiting for the next wave of VCs to figure out how to overcome this
geographic limitation and grab those opportunities which are currently being
ignored.

======
placebo
I usually don't respond to anything which I feel is just another "language
war" provocation, but whenever I see these type of reviews I'm mystified. I've
developed in many languages and frameworks, both well known and lesser known -
decades of client and server side of C/C++, Javascript, Lua, Java, Python,
PHP, Perl, Lisp. Pascal (just to name a few) in projects of all sizes, and not
once did I have the thought "this language sucks". I think there are a few
reasons for this: 1) Even after all these years, I'm still passionate and
excited at the ability to sculpt logic, regardless of the "material" I need to
use. 2) A "keep it simple" approach - no way to overemphasise this. Know the
advantages and limitations of the language and stick to what works. Keeping
things simple should be like a fractal - existing at all levels of
abstraction. 3) I'm very wary of hype. New, shiny and trendy does not
necessarily mean better, especially when the hype is in conflict with keeping
things simple. I find that when you understand the playing field, mark the
areas to avoid and keep things as simple as possible, the elegance of the
design and implementation usually makes the advantage of language X over Y
insignificant, and I feel that blaming failure on the language used is like
blaming a bad novel on the word processor used to write it.
~~~
astrobe_
> I feel that blaming failure on the language used is like blaming a bad novel

Sure. If you're a good novelist you can write something great even on a
keyboard with a broken 'e' key (btw, your 'I' key is about to break; you
should replace it asap).
But novelists don't have deadlines and when the novel is done, they usually
don't take reader requests to change this or that part of the story.
"The advantages and limitations", what works and what doesn't, "areas to
avoid" are precisely the point of that kind of review.
~~~
placebo
> (btw, your 'I' key is about to break; you should replace it asap).
haha - touché, point taken :-)
Deadlines seem like a great excuse for compromising quality. Sure, life is
complicated, the boss is demanding, the mortgage has to be paid, the children
need to be supported etc. etc. but compromising quality and enthusiasm (they
usually are correlated) because of the "terror" of a deadline will just leave
you at the mercy of the next "terror", only this time you'll even have even
less enthusiasm to fix the spaghetti. Doesn't sound like an enjoyable
existence.
Of course, very few people have the privilege of never having to compromise,
but it's never black or white and there are many more degrees of freedom to
choose the path with more quality than are implied.
>"The advantages and limitations", what works and what doesn't, "areas to
avoid" are precisely the point of that kind of review.
The "area to avoid" in the review is Node.js and considering that large and
impressive projects have been written in it, it seems that this is another
case of throwing the baby out with the bathwater.

beders
Now all of a sudden, having types and some standards to gather around doesn't
sound like a bad idea anymore ;)
I agree with one of the commenters: Lessons already learned by older engineers
(who went through similar woes with other languages/tools) are being re-
learned again and again.
The software industry is in a sorry state.
Unless you are a very disciplined team with a very strong sense of writing
modular code, don't use Node.js for any larger project. And even then, the
single-most useful function in an IDE 'Show Call Hierarchy' will never be
available when using a dynamically typed language.
That is not an issue for smaller projects. However, long before you even get
close to the the million lines of code project size, your tools will fail you.
Your debugging/refactoring times will explode and adding a new feature will
seem unsurmountable.
Instead, let's just re-write everything from scratch because the cool hipster
that wrote your backend a year ago has left for greener pastures...
I won't even try to guess the amount of technical debt produced with Node.js
and the likes each day in the bay area.
And, yes, I just used Node.js to write a Slack-bot. It was fun, took me two
hours and got me up and running quickly. That's the beauty of it. Just be
aware of the dangers.
~~~
encoderer
I've worked in three million+ loc codebases, in PHP, Python and Java. I don't
share your opinion that you need static types in these circumstances. You need
discipline, modularity, and most importantly you need to have been blessed

after a mess has already taken hold.

These types of articles make me laugh. Typically a dev with many many years
experience with one language, learned all it's quirks, standards, etc decides
to try Node.js because it's the "new hot fun toy", and expect it to work like
their old language, and realize that is not how it works, doesn't know where
to find what and fails real hard to realize that JavaScript in general is in a
huge influx of updating at this moment, which by nature propagates to Node.js.
The end result is they get frustrated and go back to their old language.

You should try to surround yourself with developers who don't have such
attitudes. I am a fan of JavaScript, I love Node.js and I will often times

languages. Just like any other language it has its strengths and weaknesses.
It's up to you to decide if it's the right choice for you.

Why? It seems like a reasonable statement - surround yourself with people who
think critically, not evangelically?
~~~
uptownJimmy
But I see your point as being precisely backwards: it's the JS crew who
constantly evangelize for their way of doing things, and that way of doing
things is completely inappropriate for anyone who isn't already expert.
"Choose your own tools" is advice for experts, and literally nobody else. It
smacks of the cowboy attitude, and that attitude is wildly unhelpful to almost
anybody doing professional work in software. Frameworks and coding standards
exist for a reason: not to be unreasonable strictures, but to provide guidance
and sanity in a staggeringly complex field of endeavor.
Many new devs and junior devs are flocking to the JavaScript ecosystem, and it
is one of the most troubled and chaotic ecosystems in all of software right
now. Anyone who is not a complete JS badass is simply not going to find Node
to be even a decent choice for learning best practices pertaining to the
larger world of application development. And I feel I'm stating that politely.
So: yet another JavaScript Pro tossing out the "choose your tools like a Pro"
advice-morsel is part of the problem, as I see it. I don't want to work with
people who toss the kids into the deep end and hope a few can learn to swim
real quick. I think people deserve a helping hand and a reasonable set of
expectations.
The JavaScript ecosystem has become self-parodying. Anyone who is oblivious to

Promises let you throw errors normally. They will propagate up the call stack
in a similar manner. With bluebird, you will also get full stack traces in
development mode and the performance penalty for that isn't too bad.

Promises are in ES6 (i don't think it gets more standard than that) and have
well defined semantics, including error handling, shared between libraries:
[https://promisesaplus.com/](https://promisesaplus.com/)
I know that Bluebird's promisifyAll might seem like a bit of a hack, but just
try it out. It works surprisingly well, and its really painstaikingly tuned
for near-zero performance loss. It will probably be both less painful to do
and more performant than any manual attempt to wrap a callback based API into
a promise one.

I gave a talk about handling errors in Node a few years ago:
[https://github.com/pjungwir/node-errors-
talk](https://github.com/pjungwir/node-errors-talk)
At the time the solution was "use domains", but I think domains are deprecated
now. It was painful enough that I have stuck with Rails since then. I'm glad
to hear that Promises are an improvement!
~~~
koolba
Domains have been deprecated since at least 0.10. As of yet there's no
replacement for them and all node apps should be using them. There's no other
way to catch " _But ... but ... that can 't happen!_" type errors.
~~~
spion
There is no replacement because they're a fundamentally broken idea. They
require the following to happen, in that order:
* V8 needs to optimize try-finally
* Node core needs to add try-finally at every single place where callbacks are invoked and make sure all state and resource cleanup is properly done to support domains
* Popular libraries need to also add try-finally handlers for the above.
As to why this is a problem in node and not so much in other languages, its
because with node callbacks, the call stack goes both ways. In other
languages, libraries mostly call their dependencies' code. In node's CPS
style, you call the library but the library also calls your closure code. The
semantics for the 2nd part aren't well defined in node - the loose law
basically says: I wont call you twice, I'll try not to call you synchronously,
and you wont throw (and if you do the behavior is undefined).
With promises there is a contract and its enforced by the promise
implementation. Since Promises actually have error semantics, you can build
resource management strategies on top of them. [http://promise-
nuggets.github.io/articles/21-context-manager...](http://promise-
nuggets.github.io/articles/21-context-managers-transactions.html) \- and
consequently there is no reason to crash your server on errors.

Domains are used for another reason: To emulate thread-local variables. I hope
that support is not going away, because it's really handy.

I agree with this article and find the Node.js community, and to a lesser
extent Javascript itself, exhausting. It seems like every 2 minutes there is a
"more" proper way to do something, which tells me that the architecture is not
yet mature, even though it's pretty old by now.
On a related note, it seems like every time you find something that doesn't
quite work correctly or conveniently in Node.js there is a "fix". Don't like
callbacks? Force Node.js to look more like other "normal" code and use
Promises. Having trouble getting Node.js to concentrate on one thing at a
time? Force Node.js to look more like other "normal" languages and use the
"async" library. And it just goes on and on and on. If I have to use all of
these other pieces and parts to be productive in Node.js I may as well just
use some other language.
I really wanted to like and use Node.js, but Javascript and the community are
holding it back.
~~~
eagsalazar2
Yes, the Javascript world is quickly evolving both on the front end and
backend, and of course that can be exhausting but I have to disagree with both
conclusions that (a) this means the tech is immature, and (b) the community's
readiness to make changes is "holding it back".
The js world is very unique in its ability to evolve quickly and things have
improved _massively_ over the last few years. Now, apart from the churn itself
and precisely because of that rapid evolution, front end and backend
development in javascript is amazing compared to most other options
(especially on the front end). So while you do have to be realistic about the
cost of the evolving ecosystem, it is just a tradeoff for rapid progress, not
a flaw.
If you crave stability, agreed, this rollercoaster probably isn't your ride.
But the evolution of node, the emergence of react/redux, es6, etc is amazing
and beautiful IMO and I'm totally enjoying every bit of it compared to the
staid mediocrity of my Rails, C/C++, and Java history.

programmarchy
Never had the problems with Node described in the article. Node forces
thinking about modularity and composition though, which I'd wager is what the
author is actually struggling with. Write functions that do one thing and
they're pretty easy to compose, even if they're asynchronous. It's really not
hard to debug what went wrong in the stack trace when you name your functions.
And I think exception handling is much worse than passing errors up through
callbacks. It forces you to think about edge cases. Not sure how python
handles this, but I can't tell you how many times I've seen Java or C# code
swallow exceptions which is much harder to debug IMO.
People really seem to have a problem with there not being "the one true path"
in Javascript, but it's not something that gives me much anxiety. Javascript
is incredibly moldable, which is part of what makes it so powerful.

Although couched as a criticism this is actually the community fixing itself.
The evolution from Grunt > Gulp > npm scripts is movement away from needless
complexity towards simplicity. Npm scripts are effectively just Bash commands
that build and manage your project, which sometimes employ small, unixy tools
written in Node.
This self correction was pretty quick, it happened within a few years.

Yes there is. It's called the Promises/A+ spec, and its built into ES6.

NPM scripts are just a different problem. See:

Already people are coming up with new "solutions" to this problem that looks
more like Grunt. It's a repetitive circle. Personally I just use Make.
~~~
Wintamute
So somebody found a project somewhere on the internet with an exceptionally
complicated build process, and you use it to say npm scripts are broken?
Sorry, that's absurd. Looking at that particular build process, I don't think
a Makefile could have been crafted to make it much simpler or smaller. In that
example, the problem lies with the complexity of what they're having to do,
not the tool.
Npm scripts are really just shell scripting, which means all the real progress
happens in the unixy Node tools that do the heavy lifting, where it should be.
It's a future proof and scalable approach for the vast majority of projects
imo.
~~~
Touche
It's an inflated example of what all npm script projects become, imo. First
you just have "test", then you add "build", then you separate your "test" into
one for the browser, one for Node, one for CI, then you need scripts that
combine those together; then you create different "start" versions depending
on environment... It blows up quickly.

That's fine, but you're missing critical features that Make provides; make
won't even rebuild a target if no files have changed.

Admittedly, my first 2 or 3 npm scripts based build processes did start to get
a bit ugly. But I'm much better at writing them now, so they stay pretty sane.

WebPack does this for me too. Also my ava tests don't rerun for files that
haven't changed while watching.
Genuinely curious, what scenarios precisely do you find this feature of Make
useful?
Also, Make isn't truly cross platform ... and since I sometimes work with
Windows devs this would be a problem.

kcorbitt
I've spent a lot of time writing Javascript on the front-end in the last year
using both React and React Native. I've found the React ecosystem to be a
sane, productive and enjoyable development environment.
Interested in sharing more model logic between our front- and backends, I also
investigated writing some new backend features using Node (we're currently
developing with Rails). But after days of research and playing around with the
available options, I came to a conclusion similar to Gavin's -- any reasonably
complex backend requires you to either roll your own everything, or try to
cobble together literally hundreds of tiny dependencies that weren't built to
go together, and then somehow keep track of all of their regressions and
breaking changes.
Node's fantastic performance and unique ability to share logic between client
and server are enticing, but I just don't trust the community and "best
practices" around it enough to bet the farm on it for now.
~~~
wrong_variable
The same problems you cite for node.js are the reasons why a lot of devs love
node.js.
Its much easier to do your own research and find the best module to solve a
particular problem you are having then to shoehorn into some larger monolithic
framework.
Also its a lot more fundamental then that - Node.js has prolly the fastest
iteration cycle for any platform out there since its so easy to create your
own module - it leads to some sort of Cambrian explosion of innovation and
experimentation.
EDIT:
Also OP seems to think callback hell and async programming is bad. The
important thing is those things are problems for python/.... too !
Its just that python doesn't have a good programming model to even begin to
address those concerns.
JavaScript at-least tries to say - "hey this is a problem we need to deal with
- concurrency is a issues we all face "
So when devs complain about callback hell - its just that they have never
tried to use python to do async in a neat way.
~~~
empthought
> python doesn't have a good programming model to even begin to address those

This isn't even close to true. Anything JavaScript has to express logic in the
face of asynchrony, Python has too. There are a half-dozen asynchronous web
servers written in Python.
There's not as much of a culture of writing APIs that way in Python because
it's generally a terrible way to program, and threads/OS processes are good
enough for basically everything except HTTP servers with absurd numbers of
concurrent connections.
~~~
wrong_variable
> There's not as much of a culture of writing APIs that way in Python because

I would love to see evidence for you making that statement. Almost every
programmer would put out their fav programming language as the 'right' way to
program.
> everything except HTTP servers with absurd numbers of concurrent connection
Once you introduce async operations in your code - you need to follow the
execution path through. http request can be async - but then what if the http
request results you doing a db lookup or some form of file handling ? you need
to make the whole thing event driven.
~~~
empthought
It's not like we didn't have cooperative multitasking for 50 years. Having
threads/processes and a scheduler is easier and safer, full stop. Potentially
long-running portions of the program don't need to be arbitrarily chopped up
to yield control back to the server, because they are pre-empted. Your system
is no longer at the mercy of the worst code within it.
Both nginx and Apache's event MPM handle HTTP connections with events while
the app backends are still using preemptive threads for running the HTTP
handler code, so it's clearly not the case that "you need to make the whole
thing event driven." You just need programmers who don't think, "well since
the browser doesn't expose threads to JavaScript programmers, clearly they are
useless."

narrator
I'm using NodeJS on a pretty big project.
Things I like:
* Async libraries make it easy to make things high performance.
* I like Sequelize as an ORM, once I figured out how the async everything works.
* The testing support is pretty good, both mocha and e2e testing using selenium
* The angular-fullstack generator was really helpful for getting started and setting up the deploy to Heroku.
* everything is open source. If I get confused with what a library is doing while I'm debugging I can just stick a print in the lib temporarily.
Things I don't like:
* "undefined is not a function". When something goes wrong. This is the error I get 80% of the time.
* async stuff silently swallows exceptions unless I put try{} catch(err) { console.trace(err) } everywhere
* There's a bit of a learning curve with promises.
* Needs a lot more automated testing than a really strongly typed language like Scala.
* Single Threaded. I know how to program using threads, so I view this as a disadvantage.
* No types. I have a lot of type checking asserts at the beginning of dao functions.
If I did it all again and my teammates would oblige, I would have probably
chosen Play/Scala. I actually reimplemnted things from a Play/Scala project I
did a while back (login/signup/forgot password/confirm account) and it took
less time in Play/Scala, even without passportJS and friends. I have about a
years worth of experience learning Scala before I started that project, so it
would probably take longer for a new Scala developer.

> async stuff silently swallows exceptions unless I put try{} catch(err) {

Huh? That's not how async errors work in Node. Try/Catch is not async, the
catch block will not magically transfer to your callback function.
You check for the error as the first parameter in your callback, that's the
standard way of error handling. Throwing errors in Node is considered by most
to be an anti-pattern.
~~~
narrator
That's nice in theory, but third party libraries may throw exceptions if
unexpected things happen at runtime. You'd still have to put the try catch
block there and call the callback in the catch block everywhere.
~~~
rhinoceraptor
That's only for non-async stuff, which is very rare. If you're using some
wacky 3rd party code which throws an Error instead of the accepted convention
of (err, response) callback arguments (or returning a promise), I suggest not
using it.

hard to CI, poor performance, memory leaks, huge docker base images due to

package management with NPM has been. We've just ditched it and gone back to
Python/Django/flask and ruby for the ops tooling.

silviogutierrez
Same experience as the author. Tons of reinventing the wheel, and hundreds of
dependencies.
The majority of established companies that say they use Node in production are
doing so as a fancy proxy. All the "serious" stuff is done on backend services
written in other languages.
Moreover, asynchrony is a concept far more advanced than most people think.
We will likely continue to leverage Node as a fancy proxy. Adding Typescript
will only help. But it's likely that as Node grows into a mature platform,
other platforms will continue to fill in the gaps that Node filled.
See for example Node constantly adding [foo]Sync versions of methods, while
Python adds first class sync support.
------
firasd
I've been on a similar learning curve with Node over the last year, and it has
certainly been a rougher incline than other languages I've used.
The whole async situation needs to settle down, it's completely unacceptable
to write code with callbacks, promises, etc. This is because they are not just
challenging to deal with, but intrinsically wrong in concept. I have to wait
for a database query to complete, then pass the next thing to do to the
callback of the query? That can't be right.

I find that JS often seems to tie programmers in the most extraordinary knots
just to implement even quite simple logic, because of the single-threaded
nature of the language.
In the programming model used by most other mainstream languages today, if
you've got some work to do that interacts with some external system and might
take a while, you'd probably start another thread for that task. You'd write
the required logic in the usual linear fashion, and just let the thread block
if and when it needs to. Modelling this using fork/join semantics and
techniques to co-ordinate access to shared resources from different threads
are reasonably well understood ideas.
Because there is no general support for concurrency and parallelism in JS, you
only get one thread, and so in most cases you can't afford to ever block it.
Consequently, you get this highly asynchronous style that feels like writing
everything manually in continuation passing style, just so you can carry on
with something else instead of waiting. That in turn leads to callback hell,
where you start to lose cohesion and locality in your code, even though
usually you're still just trying to represent a simple, linear sequence of
operations.
Async/await help to bring that cohesion and locality back by writing code in a
style that is closer to the natural linear behaviour it is modelling. However,
even those feel a bit like papering over the cracks in some cases. Async/await
kinda sorta give us some simple fork/join semantics, but as the blog post
linked from the parent shows, we have a lot of promise-based details remaining
underneath.
Fundamentally, the problem seems to be that JS is increasingly being used to
deal with concurrent behaviours, but it lacks an execution model and language
tools to describe that behaviour in a natural, systematic way as most other
widely used languages can. Being strictly single-threaded avoided all the
synchronisation problems in the early days, when the most you had to worry
about was a couple of different browser events firing close together and it
was helpful to know the handler for one would complete before anything else
started happening. I'm not sure it's still a plus point now that we're trying
to use JS for much more demanding concurrent systems, though.

Writing thread-safe code is anything but easy in languages that support
threads.
~~~
Silhouette
I respectfully disagree.
Dealing with _shared state_ is not always easy when you're working with
multiple threads. If you can't reasonably avoid that sharing because of the
nature of your problem, and if your choice of language and tools only provide
tools on the level of manual locking, then I agree that writing correct,
thread-safe code has its challenges.
However, there are plenty of scenarios where you don't need much if any state
to be shared between threads. That includes almost every example of JS
promises or async/await that I've seen this evening while reading this
discussion and the examples people are linking to.
There are also plenty of more sophisticated models for co-ordinating threads
that do need to interact, from message passing to software transactional
memory. These are hardly obscure ideas today, and I don't think anyone could
reasonably argue that for example message passing makes things complicated but
async/await/promises make things simple.

I have used Node.js in production for about 5 years now and I must agree with
the sentiment that JavaScript is "Easy to learn, impossible to master". Yes,
error handling is a little confusing at first but it stems from JavaScript's
asynchronous nature which is naturally complex for the linear mind.
My personal sentiment is to just use Promises, like everywhere. ES7
async/await will really help with this too.

I've been using Node in production for a few months now, having come from Ruby
(Rails & Sinatra) immediately before, but having used JavaEE and PHP before
that. I find it... fine.
For error handling, bluebird's typed error catching
([http://bluebirdjs.com/docs/api/catch.html](http://bluebirdjs.com/docs/api/catch.html))
is working well for me and I'm finding it analogous to my experiences with
Java and Ruby.
I'm rather used to using ORMs as well and I use Bookshelf
([http://bookshelfjs.org](http://bookshelfjs.org)) on top of Postgres for this
as well. It definitely has room to grow, but it's also fine.
I've also gained a dependency injection container (Bottle.js, see my write up
here: [https://blog.boldlisting.com/declarative-dependencies-for-
un...](https://blog.boldlisting.com/declarative-dependencies-for-unit-testing-
node-js-services-45542ceb5703#.gaf9om7zj)), which I sorely missed in my Rails
days and which gives a lot of structure to the application.
I think the biggest concerns on which I'd agree with the author are the pace
of the community and lack of agreement on things which are well-decided in
other, more well-established development environments.
That being said, there's huge potential with Node because of that. There are
more coders in the world than ever (I'm assuming) and Javascript is a great
low barrier to entry language that encourages people to explore various
runtimes. In 20+ years of coding, I've not seen this level of excitement and
engagement in a development environment. While it may be rocky for another few
years yet, I suspect we'll end up with a very productive platform, simply
because of the amount of involvement. Of course, it's totally understandable
to want to wait for that before jumping in. :)
As a relatively new Node developer, I'm much more concerned about the single-
threaded nature than the development environment, but so far even that hasn't
been a problem.

A lot of this is residual effects of the (slow) evolution of JavaScript. It
was thrust into the spotlight missing a lot of features and these features
have only recently been fixed by the language itself.
But Node has been around since 2009. 2009 JavaScript was missing _a lot_ of
features. It was basically a runtime only advanced users should use. The Node
maintainers had to make a lot of decisions that now conflict (to some degree)
with fixes that have come later to the language. They chose their callback
style; now we have Promises. They chose to throw in methods rather than return
an error in the callback (this makes it awkward to use fs with Promises
without a wrapper library). They chose to implement their version of CommonJS,
now we have the .mjs issue arise.

Been on Node and Mongo for 4 years now. Both have worked well for me.
JS has evolved a lot in the past few years, and with it came all the new shiny
tools that left us confused.
I think a year was too short for the author. Sounds like they were chasing
after every cool thing to make life easy.
Error handling is a pain yea, I've seen amateur folk try catch this and that,
I think that lends itself to being terrible.
One of the things I appreciate the most about JS is JSON. Crafting tens of
classes in Java irritates me. I find Python sometimes tricky also when dealing
with structs VA lists.
I've always stuck to the basics when I was learning how to JavaScript with
Node. I used only callbacks for 2 years until I understood what my code was
doing. Granted, I'd have spaghetti at the end of complex async queries, but I
understood what was going on. I moved to caolan::async and have been using
async whenever necessary. I barely use promises as I got confused by the early
adoption craze.
I learnt how to use Backbonejs, and a bit of Angular+React+Ember, but I found
myself comfortable using vanilla JavaScript. Only thing I use is Underscore
templates. I know I could benefit from shadow DOMs etc, but I'm content where
I am.
I think a good way to learn is to take things at bite sized chunks. I've
started using RxJS recently, and I'm loving it! I'll keep using JS as my
primary tool, but I'm slowly moving to Kotlin.

My recommendation is to just use songbird (which exposes the forthcoming

promises to be more confusing, because it obfuscates the callback in my mind,
and makes it look like ordinary function calls.
~~~
spriggan3
The advantage of promises is that you can return them as a type, you can't do
that with a callback. If you fetch something from a database , your data
access object can return a promise and let the client code deal with the
result. Promises are composable by nature, callbacks are not.
------

Really, just learn to use callbacks properly. Well, wait, actually, you should
skip that and start getting used to using promises instead--a big improvement.
Well, I mean, until next version is ready, and we can start using
async/await...until wasm makes better thought-out languages available.
Despite the sounds of this, I do like the idea of having an experimental
platform with which to gain experience using wildly different approaches to
the wildly changing world of web apps. I don't take it for granted that old
language concepts will turn out to be the most useful for the web platform.
So, I'm okay building a website for the PTA or ceramics club with this, and
I'm very interested in the experiences of others using a wide variety of

This article definitely matches with my experience. I did two not all too

easy that it completely convinced me to go with it. After a while I tried to
dig deeper and went to meetups to see whether I do things right as in a
community accepted way and if I use the right tools and so on. Since then I
refer to the Nodejs community as the most hipster programmer community I've
ever seen. As soon as a framework was getting near a 1.0 version nobody wanted
to use it anymore, experimental features were used in production code, it was
horrifying. For me that ended this endeavour, I just could not keep up with
the pace. I always wondered if it would be different if I would have worked

nodejs supports multiple CPUs.
nodejs is stable.
JavaScript is retarded fast, and it's not c or c++ or any Compiled language,
and shouldn't be compared to them because that's unhelpful as a measure.
it is the only language for the web which enables you to work in the same
language on both fronts.
frameworks aren't JavaScript.
nodejs isn't JavaScript.
JavaScript is so flexible that it can be changed to suit the needs of those
writing it, so much so that you get whole new dsl's like typescript.
there are more conversations on the internet about JavaScript than any other
language being used today.
oh and nothing scales if you don't know how to write scalable software, that's
on you, not the language.

Interesting analysis. I just finished a year of using Node for implementing an
HTTP API and a chat server, and found it to be actually pretty pleasant. I'm
not chasing the latest and greatest things, there's no ES6, no ORM, and I'm on
an older version of Node. But it works and has actually been quite stable! The
things I've missed are static type checking at compile time, and execution
speed (which is less of an issue when you're talking with databases all the
time). I'd be happy to write in more detail if anyone has any questions, but I
found I had the opposite experience of this author. The situation makes all
the difference though.

Most of the problems described in the articles can be solved by simply using
promises. Error handling is centralized in your chain and any function can
throw and just like Python or Ruby you can catch anywhere you want. As for
consistency between callbacks, promises and generators, just pick one. We
switched from callbacks to promises and it was a great move. Error handling
greatly improved and the code looks a lot nicer. No more callbacks hell. Ever.
We switched our backend from Python to Node almost 2 years ago now and it was
a great decision for us. If you handle a code base that deals with a lot of
async requests Node is definitely a top contender.
------

I think by reading the comments here and the article, its apparent that
Node.js just isn't as mature yet. If you know what you're doing, it can be
great, but for the noobs the right way to do things is not easily apparent.
Couple this with the huge choice in libraries and frameworks, makes Node.js
harder for now. I think the base is good though and given more time it will
become more easy to wield. This is typical of any new tool. And yes Node.js
has been around the block for a while, but it is still newish compared to
Python, Ruby, PHP, etc. So you're going to pay a new adopter tax still.

Can't fully agree with the article re: using nodejs in production. A couple of
years ago I decided to use nodejs for a rewrite of a web/database app that had
gotten to be complex and hard to maintain.
As so often said, it was true for me that the abundance of modules and choices
in node was at first very confusing.
I eventually figured out that keeping things as simple as possible was my best
approach. What I came up was a server relying on very few module dependencies
and written using consistent if not so elegant components. Sure it's kind of
verbose and far from totally DRY but fairly easy to understand, modify and
extend.
Key issue was node's "callback hell" style of async programming. Of course,
it's not just node, other languages (Scheme, FP, etc.) can be mind-bending in
a similar way.
The callback "inside-out" locality inversion was initially hard to grasp, but
once I caught on it was possible to get the server working the way I needed it
to. The more recent development of promises, etc., certainly provides
reasonable ways to reduce the high barriers implicated in using the nodejs
style of async programming.

Callbacks definitely become much, much less of a problem once you can turn
everything into promises.

In my opinion, JavaScript is a toy language. Looking at it, and the Node.js
ecosystem by-extension, that way has really helped me be effective with it.
Tooling has never been more important to my productivity with a language as it
has been with JS. I constantly search for tools to paper over the warts and
potholes.
------
gedrap
The only clear, objective advantage of using nodejs is that if your
application is I/O heavy (e.g. tons of sql queries which can be executed in
parallel), nodejs event system is helpful and everything you need is pretty
much out of the box. Other thing... it largely depends on personal taste and a
matter of convention.
Reading his "Why I’m switching from Python to Node.js", doesn't seem like he
was having an issue with that. And I don't really buy into the "same language
everywhere" argument because come on, how hard is it to learn python, ruby,
etc enough so that you can be productive? Not hard at all, unless you have
hundreds of cubicles filled with drones.
Anyway, it's good to see that he made some reasonable conclusions after the
experiment. That's a good sign :)
~~~
MichaelGG
Same language, in theory, is great. Reuse structure definitions. Reuse
rendering logic or even validation logic (perform checks on both, but make it
easy to get into client-side). In general, keeping things "in sync".
Also can make it easier to write in SPA style but offload rendering to the
server when you need it (particularly first-page or reloads).
Whether or not tooling is good enough to allow this (either with JS or
compilers) is another issue.
------
Clobbersmith
We use NodeJS pretty extensively at Yahoo for both front end and back end
services and it works well. While some of the complaints are valid, it's not
worth flipping tables over.
Promises are standard in ES6 and it is "the way" to handle errors. At least if
you want to stay sane.
------
btomar
Though I agree with what you all explained with the big issues with NodeJS,
you have to understand its not all of Javascript. Its only server side JS. The
creators have clarified, for heavy CPU intensive services, go away from
NodeJS. As far as frontend is concerned, AngularJS and React are just sugar
candy for user interaction and structure. Node filled the gap with an async
network application in pure JS without the heaviness of Python or traditional
languages. It is a hack as in every day people are finding new ways to use
NodeJS but I agree, there has to be best practices and less boilerplate (plus
less silly npm packages for trivial JS tasks).

I prefer to just use async
([https://github.com/caolan/async](https://github.com/caolan/async)) for all
control and error flow. Namely async.auto() can do almost any crazy flow.
------
dustinlakin
I think the switch to an async back-end can be more initial work than many
expect. It may take some time to feel as productive, but promises become
powerful and became a game changer for me over my previous work with
callbacks. Error handling also becomes manageable.
What I really enjoy is jumping into new community and getting to work with
tools that have built. Choosing the right ones can make or break an
experience. I personally enjoyed working with Express and Bookshelf.js/Knex.
I appreciate the authors perspective, but I also don't think this should deter
anyone from trying out Node. I personally have no overwhelming preference to
using a Python or Javascript stack.
~~~
xentronium
> Bookshelf.js/Knex
After ruby orms, Bookshelf felt very, very underdeveloped. Anything I tried to
do beyond "hello world" only brought me pain, especially dealing with
associations, but honestly just about everything. I guess I've been spoiled,
but getting anything done in express/bookshelf combo seemed like a chore.
------
billmalarky
Just FYI, the Koa framework makes node sane again.
Callback hell and error handling are no longer issues in node if you just
embrace generators or async/await.
We use Koa in production and serve billions of requests just fine.
If I had to go back to Express I'd say no.
------
velox_io
There's a very fine line between between removing too much essential
complexity, and leaving programmers with too many limitations. Or the other
end where the language overhead overshadows the original task at hand.
For instance multithreading should be handled by languages and frameworks
99.9% of the time. Take reading a file (something that should be handled by
the language/ framework). Read it asynchronously, structure any dependant code
clearly (which JavaScript does pretty well), if any problems are detected they
display/ log the appropriate error. You shouldn't be kneck-deep in callbacks.
------
spriggan3
The biggest problem is dealing with callbacks (and yes even promises use
callbacks , and generators need to be wrapped in a cor-routine framework in
order to work as cor-routines ).
I want to write a quick script doing some busy work , I now have to think
about synchronicity even though the script does not need to be non blocking.
Of course in these circumstances, I want to move back to Ruby or Python, which
actually let me code the thing I want to code without forcing callbacks on me.
So when you have to do 20 i/o operations in sequence, using nodejs becomes
really tedious.

Node is one of those platforms that makes me shudder every time I go looking
for solid best practices. It seems to change every 3 months. It's scary (and
cool) how fast things are changing.

peterashford
I think the basic problem is that JS is not the right solution for every task
but for the web, it's often the only tool available.
I had similar experiences to the OP. I had lots of code written in JS that I
was happy with to some extent, but all of it would have been easier / cleaner
/ more maintainable in a less crap language.
------
arisAlexis
Using babel without async await is a mistake IMO should solve almost all your
problems and errors. Also the main argument for using js in the back end is
that you have the same team working in the front-end too and in any case in
the same langage.
------
throwanem
tl;dr: "I really miss Python's bondage and discipline, so I'm going back to
it, and I'm going to hate on Node on my way out because I genuinely can't wrap
my head around the idea of a paradigm other than the one with which I'm
familiar and comfortable."
It's not even about Node. It's about anything that isn't Python, and doesn't
have the Python community's strong "there is exactly one way to do it"
tradition. I'm glad OP has realized that's what works for him. It's a shame he
lacks the perspective to understand that it's _about_ him.

A year ago one of the reasons to leave Python was poor MongoDB & JSON support,
12 months later the same author complains about the lack of a decent SQL ORM
library in js <scratching my head/>
while JS is far from perfect, his problem was he was a little bit ahead of
time- babel, standard promises & sequelize solve most of the problems. I think
Python is still superior for serverside, but JS isn't as bad as portrayed in
this post, if you slowdown for a couple of weeks to learn how to use it
properly (just like any other popular language or framework).

Small company ops guy here - a bit over a year ago, I used to joke with my

node?". More recently we've been experiencing dependency hell, which is
exacerbated by our small team not having enough time to upgrade to the latest
LTS release. Node is definitely a language that you have to _manage_. It
doesn't sit in the background and let you get on with writing stuff.
Is it the right tool for X or Y? I can't say, I'm not a dev. But it does
require a lot of hand-holding and keeping current with the zeitgeist.

Node.js, meteor, et al. is a great example of what happens when you let
inexperienced developers design a platform and run an ecosystem. Almost every
ounce of focus in this community goes to increasing developer productivity.
Operational concerns like scalability, security, monitoring, are given the
bare minimum of focus. In many years of programming in many languages on many
platforms I have never seen a worse platform and ecosystem than Node.js in a
very popular language (obviously some obscure languages hardly have anything
built around them at all).
I really think it is setting the programming world back a lot. Not to mention
what a thoroughly shitty language JavaScript is. Being able to code your web
app in one language is a neat trick, and the ability to talk back and forth
between client and server so seamlessly does kind of feel like magic, but
otherwise, this is a meaningfully worse language/platform that Visual Basic.
------
jondubois
\- The dependency instability can be avoided by specifying specific versions
of your dependencies inside your package.json.
\- The fact that the ecosystem is evolving quickly is a good thing. Node.js is
still one of the fastest growing software development platforms according to
Google trends so you should expect it to change faster than other ecosystems.
\- ORMs suck (in every language) - They always sucked; ORMs are a massive hack
intended to fix the impedence mismatch between relational DBs and RESTful
APIs. If you used a NoSQL DB with Node.js (such as RethinkDB), your life would
be much easier. Nobody in the Node.js community except your grandma cares
about ORMs because they're considered legacy technology. If you don't like it,
then you can stick to your COBOL and Oracle database.
\- Node.js lets you choose how you want to handle errors. JavaScript offers an
Error class which exposes a name property (which you can overwrite for each
error type) and you can also attach custom properties to Error objects (to
carry back more detailed info specific to each Error type). JavaScript is
really easy to serialize/deserialize so you can even design your error
handling system to be isomorphic (same error handling on the client/browser
and server). I really enjoy error handling in Node.js/JavaScript - You just
have to put some thought into it.
\- The way of writing async logic is changing. The fact that Node.js is
keeping up is a good thing. There is no single right way to handle async
logic. Most well-maintained libraries will keep slowly evolving to use the
newer features of the language but it's mostly backwards compatible (many
libraries support both callbacks and promises).
\- The standards are not bad; they're evolving and you can choose your own
styleguides for your projects. Most JS developers will adapt to new
styleguides as they move between companies/projects.

The actual information is less exciting:
_Laura Champine - Canaccord
Good morning. Thanks for taking my question. Your close rate performance was
impressive, how do you measure that?
Bob Hull - Chief Financial Officer
Laura, so a couple of different ways, so of late, we have been using satellite
imagery. So we take pictures of parking lots throughout the course of the
year. We max that up with actual transaction counts in stores. Of late we have
been actually using some technology that involves traffic counters in the
stores, which gives us close rate by day, by hour, which is going to further
allow Rick and the team to optimize labor going forward. We have tested both
methodologies for the same stores and got similar results. We are pretty
comfortable with the methodology. It allows us to forecast and see actual
improvement in close rates_

Is it creepy? They're only looking at car park occupancy in aggregate. They're

I don't get the creepy either. It seems like an ok plan to judge volume[1] of
traffic compared to sales. Might even do some analysis of what vehicle types
are going to the store.
1) I am with other posters and would have put up security cameras and done my
count that way
------
dmd
I'm puzzled why they would go to the expense of using real time satellite
imagery for this, versus mounting a camera on a light pole in the parking lot.
~~~
kfcm
This is the exact same thought I had when reading the story.
Not only would it be cheaper, but you could follow each vehicle through the
lot and figure out the traffic flow patterns better.
Plus, to tie in with this other front-page story (
[https://news.ycombinator.com/item?id=7346629](https://news.ycombinator.com/item?id=7346629)
), you could track the plates of the cars, and tie that in with retail
cellular tracking (
[https://news.ycombinator.com/item?id=5154089](https://news.ycombinator.com/item?id=5154089)
). Facial recognition still needs a couple of years. Over time, you could tie
the cellular phone, vehicle, and electronic payment (debit or credit card) to
an individual.
Continual tracking.
And all brought to you by technology. In the words of Pogo: "We have met the
enemy...and he is us."

Why not track how many times the entrance/exit doors open or close? Or add a

It doesn't sound like it would make sense to do this given that stores

How about if a hardware chain used satellite imagery to detect new structures

Isn't that a bit late in many respects though? The holy grail for a hardware
company would be knowing when a person was _thinking_ about building a new
shed, barn, etc, not when they've already bought all the wood and nails to
begin construction.
That said, we already know they're trying their damnedest to track just that.
~~~
vailripper
Isn't permitting info in the public domain? I wonder why they don't leverage
that?
~~~
TheCraiggers
A good question. My assumption is that even though it's considered public
knowledge, there is still a cost for it and it's not electronic.
For instance, in my state and/or township one can go to township office and
request a copy of all the property taxes for any piece of land, no matter who
owns it. It costs something like ten dollars and in return you get a hardcopy
with a bunch of numbers on it.
Assuming the process for getting copies of new permits is similar, the biggest
downside is cost for the information and paying for some intern or whatever to
type it in. Even if it's five dollars plus intern is decent chunk of money (I
have no idea what the profit margin is on lumber, etc). And then you have to
factor in the cost of the promotion which will eat into yet more profits.

Neat.
Satellite imagery isn't terribly expensive and Lowes has 1830 stores.
I'd bet it's a lot more efficient in the end to just buy a consistent set of

installation, maintenance of location specific concerns of cameras/sensors at
every store.

squigs25
really cool? yes. Impractical? probably?
Scanning earth using satellites is really cool. Maybe they're outsourcing this
to a central company, and paying a hundred bucks per store per month. fine.
But to be honest, there are some more effective low tech ways to catch these
numbers, for example by looking at the number of transactions, or installing
sensors on every entrance to count the number of people entering.
Seems like they're shooting a pigeon with a cannon.

The very same article goes on to state some numbers - 1% improvement vs 2%

If they can attribute it ALL to Satellite Tracking as opposed to say other
promotions/general economy & barring other accounting tricks, it is still too
little to be even attributable.

I don't understand why they don't correlate EPOS, door and aisle counters, put
it in their data warehouse, and have precise close rate based on 1) visits 2)

Still though, really cool that they have confidence that satellite imagery is
a good proxy for this.

IOS app store has created unrealistic pricing expectations - kgutteridge
http://appcubby.com/blog/5-is-the-new-10/
======
jeremymcanally
I think I prefer an open market with prices that have naturally fallen to this
point than something with artificially inflated prices. There are two things
at play here.
One, the competition in the app store right now is so voluminous and so fierce
that it's driving prices down. It's a natural phenomenon that will happen in
nearly any "free" market. To complain about it is to complain about the
essence of free market pricing.
Second, these lower prices allow for higher volume of sales. The prices have
settled here because this is what users see as the value of these apps. No
offense to these guys/gals, but I wouldn't pay $10 for something to track my
gas mileage. I'd find a free web app (if they exist) or just keep it in a
note. I get the value-add of IRS compliant reporting and such, but that's a
niche problem to solve. Charging $10 for that is fine, but don't expect mass
market appeal or uptake.
I think the biggest problem is that people who write niche apps like these
apps expect to see numbers like "Fart-O-Matic 9000" or "Angry Birds." You
won't. Accept that and then figure out what's going to make you the most
money. The trick is figuring out if pricing at $10 and making (x) sales is
more profitable than pricing at $1 and making (y) sales. For some developers,
pricing higher with lower volume is much, much better, and these developers
are typically niche applications (take a look at some of the "pro" audio apps
on iPad especially) that can handle the price difference because the people
seeking them REALLY need the value that they're offering.
An MPG tracking app that gives me nice Excel sheets might not be enough to
warrant $10 in the eyes of users, and I don't think that's necessarily Apple's
fault or the market's fault. Maybe it's just that the niche you're targeting
won't sustain the price you want, and unfortunately, that's the way the cookie
crumbles when selling software like this.
~~~
cageface
As an author of one semi-pro audio app, I can tell you that even the "pro"
apps are selling for as little as 1/10th of the price of a similar app on a
Mac. I really doubt the sales volumes compensate for that.
The big problem with the app store is that the people on the very high end of
the power distribution dictate a pricing structure for everyone that only
really works for those moving huge volumes. People now have a preconceived
idea of what an app should cost that often has nothing to do with how much it
must actually sell for in order to turn a profit.
~~~
technoslut
I'm assuming that you mean prosumer apps. I haven't seen these on iOS. The
only app that I've seen that is better on iOS is the official Twitter app.
Then again, I haven't seen traditionally big devs on the Mac release Acorn,
Flare, and Pixelmator on iOS.
~~~
cageface
For example, an excellent synth app like this would probably sell for at
_least_ $99 as a plugin for Mac/PC: <http://beepstreet.com/horizon>
I don't know for sure but I'd be very surprised if it's moving 20x the units
it would as a plugin. But if you price something like this above $10 you'll
get all kinds of user outrage because that's not what an "app" should cost.
~~~
technoslut
I'm listening to the link of the app and it is good but people have to be
aware of it. This is the third synth app I've seen. I've also seen Animoog
that was posted on The Verge.
The fault is that these apps need more advertisements. I'm willing to bet that
most don't know that they can create music with a low-priced app. Consumers
need to be made aware of this. There are YouTube videos destined to be made
with these kind of apps.
For example, I saw an Sprint iPhone ad yesterday (maybe you've seen it?) where
a guy is talking to his girlfriend while watching a game. All I gathered from
the commercial was that the iPhone was on Sprint. They didn't give me the app
or whether the game was live. The commercial became immediately insignificant.
~~~
cageface
I don't think marketing is the answer here. Every musician I know with an iOS
device knows about this app. The problem is that the potential audience for
something like this is never going to be big enough to make the Angry Birds
pricing model work.
~~~
technoslut
I've seen some that hate movies or TV but I've never seen anyone who doesn't
like music or wants ti create it, even on a superficial level.
Angry Birds is an outlier. Their success had as much to do with quiet
advertising than any blog could do.
At the end of the day, everyone wants to create – even it is something
different with an usual set of apps.
Some believe that iOS is only meant to consume. I don't believe that. Apple
has essentially released iWork and GarageBand in subsequent iPad releases.
------
MBCook
The kick the tires problem is a big one for me. I've downloaded enough free
apps that are junk. Downloading a paid app that has all sorts of problems is
very annoying, so I usually wait quite a while before buying something for
review to come in.
This makes me a little hesitant to try $ and $2 apps, even though
realistically that's a trivial amount of money. But if an app is $5 or $10,
then I really want a chance to try it first. Many apps don't have 'lite'
versions (since, IIRC, demos are forbidden).
Just having some kind of 2 hour return/refund policy would really help.
------
crazygringo
I think a lot of people may have a "mental budget" for apps -- e.g. spending
$5/mo. on apps seems reasonable to me, while spending $50/mo. is not.
So if apps were $10, I would buy 1 every couple months, instead of 2-3/mo like
I do now.
For example, I'll buy a $0.99 remote desktop connection app to connect to my
server from anywhere, that I will use maybe 3 times ever. But I will not buy
it for $10.
So I'm not convinced that higher app prices would necessarily translate into
higher revenue.
Also, remember that we can't compare piracy-free iPhone app pricing (ignoring
jailbreakers) with normal software pricing. Every purchased copy of Photoshop
"subsidizes" n other people who use it for free. So on any piracy-free
platform, you might expect prices to be lower.

This will fix itself -- _if_ he is correct that people _want_ iOS apps (read:
games) that reach parity with other handheld devices.
1\. Developers will start making simpler games to maintain profitability at
the $5 price point.
2\. Once the vast majority of iOS games are $5 and relatively shallow in
comparison with other devices, deeper more complex games will once again
contrast in value to the $5 games, allowing them to charge more money.
3\. Because of the "monthly budget" effect, I'm guessing the way this will
work is in-app purchases. X-Box has been very successful with this model. Sell
a full (but somewhat short) game for $5. Then allow the users to buy more
"content" for $2 per unit.
a $5 game That allows you to buy multiplayer content, additional story, or
other mods for a dollar or 2 at at time could easily get their average
lifetime sales per game up to 7 or 8 dollars. (and the big name games could
start at $10 and total 12 to 15)
__One more thing __
\--------------
I think it's worth pointing out that price decreases in the longer term don't
prove anything. This happens everywhere. Even on game consoles (Xbox, PS3,
wii, etc) where the games start out costing upwards to $40.
You can always to to a game store and find older games on sale for $15.

This article was written over 2 years ago, before Apple introduced in-app
purchasing. Downward price pressure is a lot worse now than then. It's more
accurate to say Freemium is the new $5. But bundling, and try and buy is now
available.

technoslut
From the post:
>Because of this, most developers I spoke with at WWDC (even the VERY
successful ones) were looking to spread risk among several small apps rather
than creating one amazing app.
This is their loss. This garbage of having 15 different apps to accomplish a
job that can be done with one will eventually be finished whether it is on the
iPhone or iPad.
Much of the App Store is about word of mouth and less about price. If you give
a comprehensive app that is worth the price and has proper dev support, the
payers will be there.
Today, I need an incredible amount of apps just to do what would take 5
minutes on Photoshop. An opening is left on iOS by Adobe to fill the solution.
Virtually no one is doing this.
Jobs' intention was not to hurt devs, but to kill piracy, reduce software
pricing and make it safe for people to get apps without worrying about
malware. Some devs may no longer exist because they can't adapt but that is
not his fault.
The main mistake Apple has made so far is not allowing a trial period for apps
or offering refunds within a certain window.
~~~
rogerchucker
I thought those "lite" versions are essentially the "trial period" apps.
Refund window is problematic as Google witnessed (and thus stopped it); but
then again, if your app cannot provide me long term value then may be you
deserve a refund.
~~~
jiaaro
What they really need is a way to link the demo and full version together in
the app store.
Apps with a "demo" version should have a seamless upgrade-to-paid-version
experience.
Some apps have done this with via in-app purchases (check out living language
for example [http://itunes.apple.com/us/app/living-language-spanish-
for/i...](http://itunes.apple.com/us/app/living-language-spanish-
for/id453341418?mt=8)) which does a great job of this and manages to get $15
out of you by demonstrating the value the app provides very effectively before
asking for money.
------
jyap
Firstly, as someone else pointed out, this was written over 2 years ago.
Pricing must also take into account the distribution power of the app store
and the actual usage medium.
iPad app prices are higher is a good example but then again this was written
pre-iPad.
------
PhuFighter
Bah. There are so many apps that I purchased that are complete junk, that,
IMO, paying a $0.99 for an app that I do use seems to even itself out. And
what about completely fraudulent apps (e.g. search for "blacklist" in the App
Store). How are they even getting in?
Given the huge amount of crap in the App store, the only real way of finding
things that are decent is to go to specialized aggregators. I go to
BoardGameGeek in order to find reviews of games. The detailed reviews there
mean more to me than the huge stinking pile of games in the App Store. There
needs to be a better way of sifting through the stuff in the App Store than
using the App Store Application itself.
~~~
drbarnard
Don't you see the problem there. The developers who build crap apps end up
being rewarded the same as those who build great apps. Essentially, you're
saying that you do pay $5 for a great app because you buy 5 and keep 1, but
the developer who built the app you like gets just $1. That sucks.
~~~
erichocean
That's the situation with "entertainment" content generally., e.g. all movies
at the theater cost the same.
And just like with movies, review sites, massive advertising to move units and
create awareness, and a general distrust of new things is where I'd expect the
App Store model to continue to go.
------
crazygringo
Also, I'd love to have a way to pay for apps _after_ I've been using them for
a while. For example, I would never have bought Instapaper in the first place
for $10, but now that I use it every day, I would be very happy to contribute
even $20.
It would be fascinating from a psychology standpoint to see what kinds of
results this might have.

At a large scale, it approaches $0/user.

It has nothing to do with pricing in itself and all with competition. Look at

because there is no real or very little competition in that area.

Show HN: Unskew My Search, a web extension for peaking into the Google black box - Unskew
https://www.unskewmysearch.com/
======
Unskew
Unskew My Search is an experimental browser extension that seeks to help you
discover how your personal search results are being skewed by Google
recommendation algorithms.
Problem: Google notoriously collects and leverages an immense amount of user
data to better improve ad targeting, click through rates, and ultimately their
bottom line. These algorithms are largely a black box, meaning we as users
don’t have insight into how our personal data is being leveraged within them.
Unskew is an attempt to identify how our search results are being impacted by
unique data associated with our accounts.
How it works: When a Google search is run with the extension installed, Unskew
takes the search term and sends it to our servers. From there, we use a
network of proxies to run the same search from a user agent with no connection
to you or your account. We scrape these unaffiliated results and return them
to your browser where the extension compares them to the results you yourself
received.
Hypothesis: By controlling for the variable of user identifying information
and removing it from the equation, disparities in search results represent
attempts by the recommendation algorithm to personally tailor results.
Identifying the extent to which this occurs is vitally important, given
Google’s near monopoly on the search space. Potential negative impacts could
involve users increasingly becoming encased in an echo chamber of their own
making in order to maximize click through rates, or could indicate the
willingness to engage in even wider scale manipulation of search results
across user accounts which are more difficult to detect.
Feedback: We hope to hear and engage with feedback regarding our methodology,
UX, and how this tech could be better leveraged to benefit users and the UX,
and answer any questions. Outside of our immediate peer network this is our
first attempt at gaining wider feedback.

My first guess would be “authoritative” ranking ignores $$profit$$ when

counting organic conscious traffic (clicks in subscription, search tab and
from external sources). TLDR it overlooks usual YT manipulation techniques
designed to make you keep clicking/watching ads. I wish I as a user could
manually trigger this hidden ranking on my search queries.

Maze62: a dense and speedy alphanumeric encoding for binary data - DenisM
http://blog.altudov.com/2011/05/16/maze62-a-dense-and-speedy-alphanumeric-encoding-for-binary-data/
======
andfarm
I'm having trouble thinking of any situations where you're free to use any
alphanumerics, but you absolutely can't use anything else. The closest thing
that comes to mind is DNS, and that's a 36-character set, not 62.
Ascii85 (<http://en.wikipedia.org/wiki/Base85>) uses a similar concept, but
using the majority of the printable ASCII characters. It gets a hard-to-beat
20% expansion on binary data (4 bytes in 5 chars) without requiring bigint
math.
~~~
deweller
I'm pretty sure the canonical use case for this would be for including complex
binary data in a URL. A URL shortener might be a good example.
~~~
DenisM
Another thing people don't talk much about is copy-paste. Double click on an
alphanumeric will select the entire thing, whereas other characters might
cause selection to end prematurely, and differently so in different text
editors.
------
waterhouse
I think this has the drawback that if you want to look up, say, bits n through
m, you'd need to process the whole string up to that point. Lookup would be
O(n) rather than O(1). Is that a problem? (I don't know, maybe people only use
base64-like encoding in places where they'd just read the data in once at the
beginning, convert it to a better internal representation, and never touch the
base64 version again.)
On the other hand, if it is a problem, how's this idea: Use strings of 129
base-62 digits to represent strings of 128 base-64 digits. I pick 128 because
it might be convenient, and 129/128 is close to optimal:
arc> (* 129 (log 62 64))
128.01522067331783
Or if decoding 128 digits at a time when you just want a couple is excessive,
you could use 17 base-62 digits for 16 base-64 digits (which has a space
inefficiency of 1/16th, or 6.25%), or 9 for 8 (inefficiency 12.5%), or
whatever.
~~~
DenisM
Random access was not a priority, yes. In fact it didn't even occur to me, not
even for a moment :)
As to your proposed algorithm, yes, it could work. It's discussed in passing a
bit earlier in this thread, here's direct link:
<http://news.ycombinator.com/item?id=2554726>
Not sure about comparative space efficiency of this vs Maze64, but we're
likely splitting hairs at this point :), it should be very close. Yes it could
work. Converting 128 characters from base64 to base62 would cost N^2 time,
where N is 128. Not sure if it's a big deal. Just another approach.
~~~
waterhouse
Hmm, and one could extend this chunking approach to Maze62. Consume 12 bits
(aka two base64 integers), but if the resulting number is in the range
[62^2=3844 to 64^2-1=4095] or [0 to 64^2-62^2-1=251], then add that extra
quotient bit to the next input (from which you'll consume only 11 bits). That
would make the worst case only take 12/11ths as long, or 109%, instead of
6/5ths as long, or 120%, as the best case (which would be the same as before).
One could extend it upwards as far as desired (probably approaching log_64(62)
worst-case and average-case space compared to base64[1]), though the integer
arithmetic would become a pain eventually. 12/11 or maybe 18/17 (105.8%) or
24/23 (104.3%) is probably good enough for most purposes. The relatively
hardcore might use 60/59 (101.7%), which x86_64 machines can still do with CPU
arithmetic (an integer multiply of two 64-bit integers stores the results in
two 64-bit registers, and you can then do an integer divide on that, which
stores the quotient and remainder in those registers).
[1] Average case: I analyze it like this. If you encode n base64 integers at a
time, then you'll encode 6n bits at a time, but 6n-1 bits if you're unlucky
and get a number in the ranges [62^n, 64^n - 1] or [0, 64^n - 62^n - 1]. These
two ranges, taken together, make 2 * (64^n - 62^n) numbers out of 64^n
possible n-digit base64 numbers. Thus, on average, you encode
6n - 1 * [2 * (64^n - 62^n)]/64^n
= 6n - 2 * (1 - (62/64)^n)
bits for every group of n characters, or
6 - 2/n * (1 - (62/64)^n)
bits per character. (Note that this analysis only applies while 62^n < 64^n <
2 * 62^n, so taking n -> ∞ gives misleading results.) The original Maze62
proposal has n = 1, and this yields 5.9375 bits per character on average,
which is pretty good. (Check this: 5 * 4/64 + 6 * 60/64 = 5.9375.) The next
few values are:
1 5.9375
2 5.9384765625
3 5.939432779947917
4 5.940369129180908
...
10 5.945595231334425
Theoretical limit:
6 * log_64(62) = 5.954196310386876
So I guess there's really not much to be gained for the average case by
increasing n. But someone pointed out that all-0 and all-1 sequences happen
frequently in real situations, so it may be worth it anyway.
~~~
DenisM
That's a great idea, and it will probably speed up possible native
implementations (though likely at the expense of scripting languages).
To deal with large runs of identical numbers (e.g. all zeroes) someone
suggested in my blog comments to XOR the input array with a result of a chosen
pseudo-random function. This will bring any dataset into the realm of average
(5.9375) except for the dataset that is specifically targeting the chosen
pseudo-random function. :)
------
jerf
Claiming this is dense, OK. That's just math. But how can you claim this is
"speedy" when you have an unpolished _Python_ implementation in hand? You need
to bench against best-of-breed Base64 implementations, not some pure-Python
comparison you may write up in the future, and for that you're going to need
to go at least C, and I wouldn't be surprised down to the assembler. Just
stick with "dense" and claim "speedy" when you've got some numbers.
(I suspect you won't beat or even tie Base64, but I'm prepared to accept that
you only got within X% of base64 but that X% is worth it in some scenario. And
maybe if you get clever enough you can prove me wrong.)
~~~
DenisM
It's speedy compared to base62.
See, the problem is that Base64 is linear is speed, but has large (non-
alphanumeric) charset, while base62 has small (alphanumeric) charset but is
quadratic in speed (at least in its straightforward implementation, the only
one I was able to find).
Maze62 is the encoding that is both constrained in charset and liner in speed.
Hence, the title.
Does it make sense?
~~~
jerf
OK, that's fair. Thanks.

If you don't mind using - and _ then the implementation is very simple. I

<http://en.wikipedia.org/wiki/Base64#URL_applications>
~~~
Acorn
Hmm, looking at python's base64.urlsafe_b64encode(s), padding is still used.
So it sounds like it doesn't fully implement the "modified Base64 for URL"
spec.
Base64 encoding also seems to result in quite long ascii strings compared to
what I threw together.
Or is there a way to use Base64 which would give results of a comparable
length?
~~~
DenisM
It's a lot longer because it doesn't know your have encoded your input data
in, essentially base-1. If you to convert it to base-256 (that is, and array
of bytes, instead or array of bits as you have now) it would produce the same
length. Yes, there is base64 implementation in pretty much any language,
though they usually use + and / for the two extra characters.
As wikipedia says, padding can be added or removed as a matter of taste: _From
a theoretical point of view the padding character is not needed, since the
number of missing bytes can be calculated from the number of base64 digits._
<http://en.wikipedia.org/wiki/Base64#Padding>
------
nkurz
My first impression is that this algorithm is going to be much slower than
Base64 due to all the branching. This probably won't be visible in Python, but
I don't think there's any way to make it really fly when optimized.
There are probably cases where this is acceptable, but I'm inclined to think
that Base32 is a better choice if larger size is acceptable, and that Base64
with domain appropriate characters is better where performance counts.
~~~
colomon
Really depends on what you want to do with it, doesn't it? He mentions
character limits in URLs as a motivation, and at reasonable lengths for that I
imagine Maze62 in Python will be plenty fast....
------
peterbotond
recently, i needed to encode/decode similar data, and base64 with a variable
64 chars seemed to work just as good. say, - or / are problem chars, then make
another set of 64 chars which would have a comma and a dot or alike and there
you go. keep the sets in a table or somehting and use the first 2 chars as
indicator which set of 64 to use for that data.
------
jtchang
Cool stuff. Can you post a few examples of the encoding?
------
andrewcooke
why is base62 quadratic?
~~~
dfox
Naive implementation certainly is, as it involves one multiplication (of
number whose size depends linearly depends on number of previously processed
bytes) for each input byte and one division for each output byte. But on the
other hand I have this feeling, that more effective implementation is possible
(and actually used by modern compression algorithms like RAR and LZMA).
~~~
andrewcooke
but couldn't you have a stream algorithm with modular arithmetic?
[edit: i thought i had a good demonstration of this. actually, two. but both
were wrong. so it does seem to be non-trivial...]
[edit 2: open stack overflow question:
[http://stackoverflow.com/questions/3545931/efficient-
algorit...](http://stackoverflow.com/questions/3545931/efficient-algorithm-
for-conversion-between-numeral-system) ]
~~~
DenisM
If we could, we wouldn't call it base62, as base62 normally means converting
the entire "bigint" (all bytes of input data as one big number) into base-62
representation. At least that's how baseXX has been used to far (I searched
the web before doing this), and I am in favor of sticking to that naming
convention. Agreed?
Now, whether we could come up with such streaming algorithm I'm not sure. I
tried solving this problem, and this is what I came up with. Maybe I haven't
tried hard enough to go the other route... I guess you could simply slice the
incoming stream into a set of chunks, each small enough to make bigin base62
conversion fast (which is square of the size of the chunk), and yet large
enough to obscure the occasional loss of space at the chunk boundaries... I
guess that would be an option...

I enjoy reading posts like these for the perspective they give me on how
differently some people do things. My wife and I by contrast are ridiculously
over-prepared. Dated for a year before moving in together, lived together for
two more years before deciding to get married, waited another two years to
have a kid, and then invested enough time into learning about childbirth that
every medical professional we talked to though the whole pregnancy and labor
assumed that we were both in the medical field (seriously, I know way more
about the anatomy of the female pelvic area than any other part of the human
body because of this).
She's a month old today (coincidentally also named Zoe).

sgoraya
Congratulations - The journey only gets better!
I've got a 8 month baby boy and wonderful wife that are the center of my
universe right now.
I got a chuckle about the time invested into the childbirth process; my wife
teased me about knowing more about having a baby than she did ;)
That said, I am spending less time on my business - whereas in the past after
coming home from the office I would take a break for dinner, the gym, then get
back to my desk at home and work into the night. That schedule has changed
drastically - I would rather spend the evening playing with my son and hanging
out with my wife than working. After the little one goes to sleep though, I
try to put in a couple hours of highly focused work.
Overall, I think I'm almost as productive (after the first 4 months) - when
you have a child, the need to maximize time and effort are amplified.

Getting a woman pregnant and fathering a child are two entirely different
things. I hope you have found the perfect balance between being a father and
running a startup.
Hint: the proper balance is heavily leaning towards the child.
~~~
tptacek
I upvoted you, since I've had the (apparently not so) unique experience of
having my first kid at the same time as my first "real" startup, and it was
fraught with peril. I agree that the preachiness of your comment is grating,
but the tone of the blog post you're commenting on kind of warrants it.
That said, the real risk in this scenario isn't to the child; the risk is that
you'll demolish your relationship with the other parent. The kid will be fine
for the first year or so. They're basically very smelly houseplants until they
get to crawling age. You're constantly terrified that they're going to
randomly die on you, but the rules for preventing that outcome are
straightforward and hard to forget.

_You're constantly terrified that they're going to randomly die on you, but
the rules for preventing that outcome are straightforward and hard to forget._
Changing the recommendation from sleeping face-down to sleeping on the back
has reduced the rate of SIDS (Sudden Infant Death Syndrome or something like
that) in Sweden by roughly 80% since 1992. There was a peak at 1.1 per 1000
live births in 1991, and it's now at 0.25 or less (in 2008 it was down to
0.13)[1].
Some babies sleep better face down, but I prefer somewhat uneasy sleep for six
to nine months (until they can turn over by themselves) to a tenfold higher
risk of death.

I've read some of the actual studies you've quoted (and others), and they seem
to indicate that infants that sleep on their backs fair slightly better in
statistics. Some also blame heavier blankets and "bumper pads" (the pads that
wrap around the bars at the base of the mattress).
As I mentioned elsewhere, my understanding is that it's merely a
recommendation based on statistics with no direct correlation.
My babies went on their backs, because even a %.001 difference is enough for
me to play the game, seeing as I don't know what I'd do if one of them passed
away.

_a recommendation based on statistics with no direct correlation_
"a recommendation based on statistics" usually means there is a correlation. I
think you mean that it may not imply causation, which is true of course.

If you didn't make the jump to the footnotes, I thought this was great:
"One of the Y Combinator questions asked you to name one non-computer system
that you’d hacked in some interesting way. My answer concerned a man-in-the-
middle attack I once did on Craigslist personals. I placed an ad as a woman
seeking a man, and as a man seeking a woman, and then simply crossed the email
streams by forwarding mail from one to the other, and vice versa. Most
Craigslist personals didn’t even have photos back then, so the switch went
undetected, even after the couples had met. I handed off the relationship by
telling one that the other’s email address had changed, from my fake one to
the real one, and likewise vice versa. For all I know, those couples are still
together and having kids. They probably don’t know to this day what happened
or what brought them together."

The most important thing you can do for your child is love their mom.

araneae
How could he possibly do that if he got her pregnant on the first date?
95% of the people I have gone on first dates with would have made disastrous
life partners. It's kind of a lot to ask of him.
~~~
my_account
He doesn't love the woman, you can sense it in the writing. Probably doesn't
even like her that much. I picture a scenario where he drifts toward his man-
cave aka start-up, when domesticity comes calling. Michael Lewis wrote a book
about his domestic situation, but one never doubts he puts wife and kids
first. That said, he and the wife were a little more conventinal given their
approach.
~~~
antongm
I won't comment on the love angle, other than to comment that our current
notion of love is a 19th century European invention that doesn't really exist
in most traditional societies. There's ways of getting along that don't
involve long courtship, touching poems, or passionate romance.
And it's funny you mention Lewis. The mother gave me that book as a present
last March. Great book. I should note, he didn't particularly love his
children at all at first...until the child was stricken ill and he had to care
for him.
~~~
araneae
Our "current notion" of love may certainly change, but the neurophysiological
fact of love does not (at least, not on the same timescale). I don't know what
the original commenter was referring to when he said love, but I rather think
he meant the emotional connection, not poetry (who think that has anything to
do with love nowadays anyway?)
~~~
dbrannan
Love has many meanings, yes. If love is a stretch for you (or does not come
naturally) at least try your best to respect their mother, treat her kindly,
speak well of her, support her the best you can, and encourage her. These
simple steps will do more for a child than you might realize - I don't care
what the media says, parenting is really a team effort.

leecarraher
this description of linear scan kNN may be a bit tedious for the hacker news
crowd. here's the gist (in python):
def knn(y,X,k):
d = len(y)
least = [(float('inf'),[float('inf')]*d) for i in xrange(k)]
for x in X:
d = 0.0
for i in xrange(len(x)):
d+=abs(x[i]-y[i])
if d < least[k-1][0]:
least[k-1] = (d,x)
least.sort()
return least
Sorting even for linear isn't the best idea but keeps the algorithm terse. A
data structure like a priority queue should probably be used instead of an
array.
and one should use a kd tree or ball tree for exact, and LSH-knn for inexact
in practice.

Automatic server hardening framework - dewey

allendoerfer
Seems like a nice and comfortable way to set sane defaults for nginx, Apache,
MySQL, PostgreSQL and some Unix stuff - but they really should have been set
by each software in the first place.
I like, the private touch the screencast and the developer-designed website
gives the project, even if part of a big company. This actually raises its
credibility.
~~~
ams6110
_they really should have been set by each software_
Yes, and it seems to me that distros (at least those intended for
"enterprise") should be hardened by default also. If I install RHEL or OEL and
then have to run a Chef or Puppet config to "harden" it, something is wrong.
~~~
jlawer
Well, thats been tried and rejected by the user base. If you harden too much
it becomes a real PITA to do anything productive (SELinux running in strict
mode).
RHEL aims to be secure, while also remaining fairly compatible with previous
versions.
Red Hat do have documentation on how to harden, but most users don't use it
and instead turn SELinux completely off as one of the first configuration
steps.

Very cool, but seems like it would be nice to have the hardening steps
documented outside of code too (for those of us with more exotic provisioning
tastes).

SimCity should do a galactic sim to design species - vtempest
After playing SimCity, I think: Why not go galactic? Imagine a version where you are the god-like consciousness of the universe. You input various characteristics of how you want the universe designed and the species that live on various planets. You watch them evolve (like Conway's game of life) and eventually they will contact each other and compete for planets. SimStar Wars. It's like Starcraft but you get to design the way planets and various species are structured, instead of playing for a side. Would a more Star Trek Borg-like species beat a logical Vulcan species? Ah what a video game that would be, the grandest of them all.

yareally
I not sure if the OP is being serious or not after reading his description and
realizing he does not mention spore once. EA is honestly not the company I
would want to make this kind of game though. I played Spore when it came out
and although it had a lot of potential, you could feel it was rushed and
limited to what was envisioned. Combined with the way EA has changed their
business model in recent years, I fear for what a reincarnation would look
like.
If I had to choose a AAA studio/publisher over alternatives, would go with
Firaxis, makers of Civilization. An Indie developer though would be the best
bet to getting a game that isn't made for just casual gamers.
Kerbal Space Program[1] has a some of what the OP might want, but with a more
narrow, realistic scope. Also allows modding for extending the game.
Also Civilization 4 had some great mods (including several Star Trek ones)[2].
They were good enough, you actually felt you were playing a turn based space
sim and not one on a planet. Not sure if any are out for Civ5 yet. I own it,
but I have not had time in a while to to play much.

New male contraceptive may be submitted for Indian approval this year - rihegher
https://www.bloomberg.com/news/features/2017-03-29/a-new-kind-of-male-birth-control-is-coming
======
WA
This is big. This is the future of contraception, because it works, it's
incredibly cheap, it has (almost?) no side effects. All current solutions are
a joke.
Hormone-based contraception feels like something from the middle ages. It has
serious side effects, it has "harmless" side effects that aren't even related
to the pill anymore after years of intake, but still an annoyance (migraine,
headaches, yeast infections, high blood pressure, ...)
Non-hormonal contraception has its own negative aspects:
\- Copper IUDs can cause a lot of pain, inserting them isn't that easy, they
are ethically troublesome (eggs can be fertilized after ovulation, but the
copper IUD prevents nidation)
\- Natural family planning methods are way safer than many people believe (the
sympto-thermal method), but don't allow unprotected sex during fertile days
\- Condoms are way safer than many people believe as well (as long as you use
the correct size) and won't go away because of STDs, but are a bit annoying in
relationships
And there really aren't any other alternatives right now. The state of
contraception in 2017 is incredibly sad and RISUG is the first attempt, which
truly can _disrupt_ (and I don't use this word lightly) the entire industry.
It will require some social shift. Men must be willing to take responsibility
for contraception, but it's already happening: Recently, the pill for men was
stopped because of side effects, but the men were disappointed. They WANT to
have alternatives to condoms.
~~~
jwdunne
Bang on.
Me and my partner were planning on me getting a vasectomy in a year, when her
implant runs out.
We've had to bring that forward a year because one side effect is also a
symptom of cancer or polyps.
After removal, she experienced a huge lift in energy levels and greater
stability of mood.
I have 2 children so a vasectomy isn't so bad an idea. Even still, it is an
invasive and permanent treatment and I'd prefer something less so. Nobody
likes the thought of a scalpel down there. Even a physician who wants to get
it done.

The tech in this article allow sperm through but damage the sperm. The
Parsemus tech seems to block the tubes entirely.

tgtweak
Untrue, actually they both use the same system (and almost identical
formulation). The difference being the focus on the FDA process and US market
that vaselgel is taking, you can see the cleverly worded non-answer on their
own FAQ, quoted below. They do "filter" the vasdeferentia and not block it.
This is actually preferential as it can alleviate a small chance of pain or
sperm granulomas after a vasectomy, also quoted below.
_Although Vasalgel and RISUG® are based on the same concept of using a
polymer gel injected into the vas deferens, the formulations are not the same.
And RISUG has been developed and tested in India over multiple decades, while
Vasalgel is being developed in the United States to conform to the latest FDA
and international codes of production and safety._
And
_only a small percentage of men who have had a vasectomy experience chronic
pain (1-2% according to the American Urological Association). Our current
understanding of Vasalgel is that fluids can pass through the gel, but sperm
cannot. This will likely reduce the incidence of back-pressure. Sperm
granulomas are formed when the vas deferens is severed in a vasectomy and
sperm leak into surrounding tissue. Since injection of Vasalgel does not
involve cutting the vas deferens, this should not be an issue._
Notice the non-answer below:
_Our understanding is that Vasalgel works by blocking or filtering out sperm.
In the past, RISUG (a different product) was described as working by shredding
sperm by an electrical charge process as they went past the contraceptive that
lined the walls of the vas deferens. Vasalgel makes no such claims._

I remember reading about this maybe 6 years ago. What was memorable was that
the gel was even cheaper than the syringe. It's sad how slow these things move
and that we're not going to have that in North-America for a good time.
~~~
Broken_Hippo
I wish it could go faster, but the truth is this is exactly the sort of thing
that should go slowly. It is much better for birth control to have a certain
effectiveness, after all. Since this is an injection, probably best to have
good tests with longevity as well. It isn't bad to go back every couple years
for this, but this is the sort of information one needs to know upfront.
Unfortunately, finding this initial stuff out takes time.
~~~
TheAdamAndChe
A problem in the US is that the company that wants to sell this is the company
that needs to pay for the studies required to make it legal. However because
it is so cheap, it's difficult for the company to make a profit. The same
thing can be found with many supplements. For example, N-acetylcysteine has
shown to be helpful in several forms of addiction and mood disorders, but
because it is so cheap, no company will front the money needed to make it a
medication. We need to change the system so that the research is paid for by
the government somehow, in my opinion.
~~~
aianus
> However because it is so cheap, it's difficult for the company to make a

Why does it have to be cheap for the consumer? They can charge $5k for this
(honestly a bargain) even if the gel and syringe cost $5 to make. Isn't that
what patents are for?
~~~
TheAdamAndChe
Many of these drugs are cheap because the patent has expired. Many times, it's
not until the patent has expired that they learn the new use for the drug, but
by that point, they can't make money off of it.
It shames me to think that we have a for-profit healthcare system.

I wonder how this would effect STD rates in areas with bad sex ed? I could see

relationships.
~~~
torrent-of-ions
I can't see how it would have a positive effect. HIV infection rates in the

Sounds like interesting option, but 98% efficiency seem pretty unreliable, so
I will still be at risk 2 times out of 100 intercourses when not counting
other factors.
Personally I consider immediately after having second child vasectomy, though
if wife would agree I would do it already now (one child is more than enough
for me) plus store sperm in bank just in case if changing mind, since I heard
reversing vasectomy ain't that successful. Seem safer with 0.15-1% failure
rate than this method.

Efficacy for contraceptives is almost always measured _per year_. That is, of
every 100 couples using this method for a year, two will become pregnant. As
the article says, this is about the same level as (perfect use of) condoms.
~~~
Markoff
seem very inaccurate since every couple has very different frequency of sex
per year, some couple can have 100 intercourses, other will have 20 and they
have same odds according some average couple?
~~~
scott_karana
The inaccuracy would depend on the sample size of the test groups. It might be
useful to get standard deviation, or maybe the methodology excludes outliers?

This seems quite perfect in theory. Not invasive, lasts for a long time, just
one shot and then you're done... I hope the clinical tests will bring good
news for that project, because this is something I would do if it comes on the

~~~
JshWright
While it is far _less_ invasive than some options, it is still an invasive
procedure, and not without risks.
Obviously, for many patients, the benefits will massively outweigh the risks
(assuming the clinical testing bears out the initial results).

Batro
Yeah, I spoke (or rather typed) too fast : it's still an injection, you're
right, but at least it's not a complete surgery operation.

Ericson2314
Technically I beleive the only efficient systems are those where it is known a

responsibility of one sex or both. I agree with you: both sexes may be
overkill but is the only fair option.
~~~
manmal
I don't get it - what does that kind of fairness buy you or society? If it's
enough when one side takes contraceptives, what logic argument is there that
the other side must do the same? Economically (time, resources, even

sea) this does not make sense.

Nope, that is not the reason.
The reason is that they don't know it exists. Condoms are OK, but for that
drunken one night stand, not necessarily good enough. Female birth control has
the problem that you have to trust your partner (spoiler: not everyone is

They will not give you a vasectomy in the US as a young childless man.
Something about 'changing your mind later'. It's very patronizing.

Definitely patronizing!
Not only that, but even when a woman is in obvious pain and having issues
which only a hysterectomy will solve (ovarian cysts) - if she is under 30 or
so, they won't give it to her.
My wife and I made the decision not to have children a long time ago. In the
meantime, she's had times where she went into the hospital ER for pain caused
by ovarian cysts. She attempted to inquire about a hysterectomy from her
doctor after these episode, only to be rebuffed about "what about having
children later", etc.
To this day she still has problems, but it has waned greatly now that she's
approaching menopause. She'd still like to do it just to stop having a period,
but it's no longer the crazy amount of pain that it was.
I found it frustrating for her that as an adult, she was being restricted from
making choices about her own body to improve her health and quality of life.

Stupid question but why would a hysterectomy (removal of the uterus) prevent
cysts from forming on the ovaries? The ovaries are the hormone producing
organs.

Testosterone will also do this. There are long release esters so you only need
an injection every few months. Even with a bimonthly shot, it costs about
$10/mo. (On mobile, but there was a study in China with T undecanoate showing
amazing effectiveness.)
Downside is that in the US, testosterone is, hilariously, Schedule III. But 5
minutes with Google should have you sorted. Can get OTC in other places.

... Obviously my comment was meant as a suggestion to look into things and
note the availability of a well known substance that already accomplished
birth control in men. It wasn't intended as a "read this comment and start

You're of course free to attempt to convince a doctor to prescribe. Or you can
buy the drugs and get a $100 blood test to verify it's real as well as do a
fertility test. It's just an affront to liberty to pay a gatekeeper to allow
you to change your own hormones.

Indeed, the cultural "importance" will be revealed in time. However, I fear

There used to be a time when we as a society valued things like self-control,
discipline, and tradition. No more.
What you are alluding to here is a world where we are ruled by our emotions
and our basest desires without the fear or potential for having to deal with
our actions. To divorce sex from children is to misunderstand intimacy, the
family, and the entire underpinning of our society.

What all have we lost due to birth control?
~~~
tlb
Before birth control, it was an accomplishment one could be proud of to have
children at the right time. It required stable relationships and self-control.
Your family and church would give you a lot of respect if you succeeded, and
contempt if you failed. It was a test that separated the virtuous from the
lazy, weak, and sinful.
When such hardships are made optional by technological or social progress,
most find new challenges to conquer but many regret their loss.
Birth control is old news in the Western world. But the cycle will repeat with
new technologies. Suppose you're serious about fitness, you spend hours every
week spinning and cross-fitting, and your abs are rippling. And tomorrow, a
pill is developed that lets everyone be perfectly fit with zero effort. What
do you get for all your hours at the gym? Can you imagine being bummed that
everyone else is getting for free what you worked so hard for? That might give
some idea what pre-birth-control nostalgia is like.

The problem with this lovely wheat-from-chaff heuristic is that "failure"
results in the introduction of a new human life into a world that may not be
prepared for it and will be strained ecologically for its existence. I would
much rather have a world where the lazy, weak, and sinful pop pills towards an
ecologically sustainable population than one where the virtuous are lauded for
bringing five or six new people into existence, but, you know, at the "right
time".
~~~
tlb
Me too. The failure mode of pre-contraceptive society (unwanted children) was
terrible. But human nature is what it is, and many people are willing to
accept terrible externalities in order to have a means to display their
comparative virtue. The recent attack on universal health care in the US is an
example. Many voters seem to desire a world where people who have their
financial shit together will live, and others will die.
For a clear-eyed view of these less inspiring aspects of human nature, read

There is a lot of social commentary on this thread.
Unanswered however is, "How will this affect relationships between men and
women"?
The "MGTOW" crowd laud this development, arguing that once control of
fertility is in the hands of men rather than women (a woman can always
"forget" to take the pill)... something good, as they define it, will happen.
(IANAMGTOW - I am not a MGTOW)
In terms of total fertility rate, what does this mean for a country/nation
when one population group greatly restricts having kids in terms of moral
suasion, societal acceptability, etc. while offering money to those who do
have kids? e.g. upper middle class (children discouraged, at least beyond 2
kids) vs. other classes in society (have a bunch of kids).
Living in the USA I have often heard complaints along the lines that we seem
to be "discouraging the smart and hard-working people from having kids, while
paying stupid people to have them".
~~~
SamBam
How is any of that different from the contraceptives that already exist?
Further, your notion of "Idiocracy" (believing that the "smart hardworking
people" have fewer kids) doesn't match at all with the fact that IQ keeps
rising in every generation in the US, and fewer people are poor or jobless
than they were in the 50s or before.
~~~
patrickg_zill
I would point out that you are relying on government statistics for your "poor
or jobless" point - and many have pointed out sources of bias that call those
stats into question; and also, you are assuming that the Flynn effect will be
ongoing rather than just reflecting a topping-up due to better nutrition and
more widespread education.
Others have calculated that USA/UK have lost as much as 14 IQ points since
Victorian times. see

~~~
SamBam
You quoted "USA/UK have lost as much as 14 IQ points since Victorian times"
and cited a tabloid article.
Presumably the reason that the parent commenter thought it appropriate to to
mention that it was a tabloid article was because it used the standard tabloid
technique of putting a sensational notion in a headline that is almost
entirely unsubstantiated in the text.
You offer as support several links, mostly just proving that people exist. But
your first link, with actual information, completely refutes your statement.
[1] It refers to the effect that IQ has risen by 3-10 points per decade for
several decades, and in the past few years it " _may_ " have leveled off, or
dropped by 1.5 points.
The actual author of the study has said that leveling off is to be expected,
and any "decline" is quite likely noise due to chance.
But _regardless_ of whether the 1.5 point decline in the past couple years is
true, the entire article the opposite of the claim that we have lost "14 IQ
points since Victorian times," since you cannot reconcile that with the Flynn
effect actually being discussed in the article.
Combing down through the tabloid article, almost every other study refers to a
decline of "about 1 point." Your headline claim is one single interesting
(though bizarre) study that uses reaction time to try to estimate IQ, and
tries to compare it to reaction times in studies from the Victorian era. [2]
As you can imagine, published responses to this article from other scientists
has been that of skepticism, to put it mildly. [3]

I covered this in my original statement with the comment about "topping up"
the Flynn effect.
The rest of your comment doesn't apply to my point, seeing as I was pointing
out that it was easy to find the actual people at the actual uni's quoted, via
simple Google searches, and that their published papers did in fact make the
various claims.
Thus the original response of "this is from a tabloid" added no value.

I think the only value it sought to add was to point out that the source cited

It doesn't even make sense. Women have the possibility to abort a pregnancy
while men have no say whatsoever (in regions where the big pharma companies
are coming from). So the argument that women would do more for male birth
control is somewhat strange considering they have all the power in their hands
right now.
~~~
colanderman
That's adversarial thinking. If the man and woman are in a trusting
relationship, the question changes from one of "power" to responsibility.
Today, most reversible contraceptive methods (pill, rhythm, IUD, abortion)
rely on the _woman_ owning responsibility (one which they may be unwilling or
unable to carry out). Male contraception relieves women of that burden.

able to unilaterally decide when a couple starts having offspring. (As if men
were not legally beholden to care for their offspring.)

\- I'm not paying money to have needle injecting chemicals with unexplored
potential (longterm) side effects into my private parts when the potential
success rate is that of a condom. Condoms kind of work.
\- "The pill" is a bit more than just a contraceptive. A variety of issues,
ranging from skin problems to hormonal imabalances are regulated through the
pill, which quite efficiently normalizes outliers in female hormone levels
alongside acting as a contraceptive.
The pill is rarely "just" a contraceptive. It reduces menstrual pain
significantly and allows women to forego the pleasure of planning for a week
of unnecessary discomfort every month.
Every woman I've been sufficiently intimate with to have such conversations
describes the daily pill as a small price to pay for all the benefits it comes
with.
A male vasectomy is 800 bucks and certainly reversible.
~~~
creepydata
Stop your patronizing bullshit!
I have taken the pill for years I feel like I am ruining my body. I have side
effects. I switched brands, I switched to the shot (that was much worse),
every one is awful. I put up with it because I won't risk unwanted pregnancy.
It's the less of two very evil evils.
You're also ignoring the large population of women who the pill is
contraindicated for. It also requires regular doctor visits and requires you
to to remember to take it.
I'm not saying it's great for some women, it certainly is. People also take it
for non contraceptive reason. Not great for everyone and not for me.

who avoided the pill because of its horrible side effects.

The Infinite Set: On '2001: A Space Odyssey' - prismatic
http://reverseshot.org/symposiums/entry/2013/space_odyssey
======
GuiA
What a great essay. Worth the read.
_" Upon reaching Jupiter, Bowman is guided into a wormhole, triggering
Trumbull’s bravura psychedelic sequence. On either side of a perpendicular
line dividing the screen, two vertical planes of brightly colored lights and
shapes emerge, rushing past and out of frame, giving the illusion that Bowman
(glimpsed in a juddering cutaway shot and then in paralytic stills) is racing
through a corridor of infinite dimensions at speed-of-light intensity. Modeled
in part after the avant-garde films of Jordan Belson (who later created
special effects for The Right Stuff) and fraternal animators James and John
Whitney (collaborators with Saul Bass on Vertigo’s title sequence), Trumbull
recreated screen space with his slit-scan technique, combining long exposures
of circuit board diagrams, Op Art prints, film negatives, and electron
microscope photographs for this sequence, which cleverly exploited the simple
x and y axis geometry of an ideally proportioned widescreen frame."_
That scene is probably my favorite movie scene of all times. My dad was a big
fan of _2001_ , and made me watch the movie when I was 13 or so- I missed a
lot of the subtleties, but that last part of the movie added a new layer to
existence that I could have never conceived of before. For a nerdy teenager
who was really into science and sci-fi, it was mind blowing to be exposed to
such an artistic depiction of the subjectivity of the human perception of time
and space, and the ambiguity of reality.
It's interesting to read the techniques that went into making it - it's a very
creative use of the medium. I can't help but feel that CGI has put special
effects designer into a box of vertices and polygons, resulting in special
effects that all look the same. I certainly can't think of a single movie that
has something as unique and distinctive as the wormhole scene in _2001_. I had
high hopes for _Interstellar_ , but it fell very flat (there are some groups
doing very cool work in more traditional animation however - I really like
Studio Laika, for instance).

So much of what Kubrick did here has never been replicated, few have even come

However, that's not to say the end result is particularly enjoyable for me to
watch. It's long runtime wears down on me and by the first hour I find myself
wanting to watch many scenes at 1.5x speed just to feel like I'm watching a

Films have been speeding up for a century, in two ways. Editorial geography
disappeared in the 1960s. Editorial geography example (not mine): Bogart gets
phone call. Bogart gets up, walks out door. Bogart walks out door of building,
gets into cab. Scene of Bogart in cab. Bogart gets out of cab, pays cabbie.
Bogart walks into apartment building lobby. Pushes elevator button. Shot of
elevator indicator coming down. Doors open. Bogart gets in. Shot of elevator
indicator going up. Elevator doors open. Bogart gets out, walks down hall,
rings doorbell. Lauren Bacall opens door. Bogart goes in. That's editorial
geography. At one time, it was felt that audiences would get lost without such
a sequence. Today, writers and directors would skip directly from the phone
call to an interior shot of the apartment. Jean-Luc Godard's "Breathless"
(1960) is said to have put an end to that.
Related to this is average shot length as a metric.[1][2] "2001" has an
average shot length of 13 seconds. At the other extreme are the Bourne movies,
which are now down to around 1.1 seconds per shot. James Bond movies have sped
up over the years, with "Dr. No" at 7 seconds and "Die Another Day (2002)" at
2.4 seconds. This is an industry-wide trend.
Trailers are insane. Trailers routinely break the 1 second barrier today.
So there's been a speedup in two dimensions - removal of unnecessary context,
and shorter shots. To a modern viewer, 2001 looks quite slow-paced.
With enough short shots, films can conceal the lack of a plot. (This is a
problem with effects-heavy movies. After you leave the theater, you realize
the plot made no sense. But it was a great effects demo reel.)

That's why I can watch trailers of new movies and feel like I've seen enough.
Usually you get the gist of the plot (or lack thereof) along with plenty of
spectacular scenes making the rest of the movie unnecessary.
~~~
taneq
The problem is that most trailers actually _don 't_ give you enough to really
understand the movie, and they're generally pretty good about not giving
spoilers... but they're produced to give you the _impression_ that you've
basically seen the whole movie. So it's really easy (I do it too) to dismiss
an entire movie based on a 15-second trailer.
Unless you're talking about the Tomb Raider movie. The trailer with the fight
between Lara Croft and the robot is basically the first 5 minutes of the movie
and you can stop watching after that. :P

As regards the wormhole sequence, one must appreciate the innovation in
technique, meticulous execution, groundbreaking visuals, and also the
incredible cinematic boldness in showing such a long, strange sequence in
theaters at the time. Truly impressive and meaningful work, which left an
indelible mark on cinema over the past 5 decades.
That said, a part of me has always wished this sequence gave more thought to
the physics and what it might be like to visualize the experience of traveling
through a gate/wormhole like this. I don't think the coloration, visual
patterns, or sequencing represents much understanding of the then-current
physics theory on what this sort of thing might possibly be like, and I'm not
sure it even captures it well in the abstract.
Amazing cinematic work which moved the industry forward in a positive
direction. I just always wished they'd somehow been able to go even further
and applied the same brilliance of vision and execution in technique to an
even more refined concept that incorporated some viable notions of the
possible/theoretical physics involved in traversing through space-time like
this.

'Interstellar' did some of that, and they had to hire Kip Thorne as a
consultant, and run a render farm to raytrace the relativistic effects.
I'm not sure the theory was quite at the same level in the '60s, and the
cinema technique was definitely not the same. It would have been a lot harder
to do any degree of realism.
~~~
erdevs
Yeah, Interstellar definitely scratched this itch for me, and I appreciated it
for doing so.
Certainly the theory has developed greatly since then. But being even somewhat
informed about the contemporary physical theory would've made the sequence
even more impactful and satisfying, for me personally.
I don't think technique would've necessarily required greater complexity or
difficulty. For example, one might have used the same planing technique, but
used different patterning and colorization, based on more mathematically
derived outputs. Not suggesting any kind of simulation or super-advancement.
Just using the same technique, but informing the visuals based on more
physical theory.
~~~
TheOtherHobbes
I think that would have been literally impossible in 1969.
Firstly there was no theory of wormholes back then. Black holes were
incredibly obscure mathematical abstractions in physics journals that weren't
accessible to most people.
Secondly, this was 1968, when the world's faster supercomputer ran at 36MHz.
Evans and Sutherland were just getting started when 2001 was being made. There
were no GPUs, no digital frame stores, and monochrome bitmapped displays were
still exotic.
It's easy to take computers for granted today. You can plot and animate almost
anything, and you can do it at home - or on your phone.
Not so in the late 1960s. Mathematically derived animations would have needed
a mountain of cash to pay for computer time just to get something very rough
and approximate.
~~~
erdevs
Why do you assume computers would've needed to be involved? One can plot
space-time warping by hand. Indeed, Einstein had no benefit of computer
assistance in developing his theories of relativity and gravity warping.
Why assume a complete theory of black holes or wormholes was necessary?
Clearly the _concept_ existed. Clearly we had General Relativity. One could
imagine a more speculative but still physics-based visualization of what might
happen in traveling through such a nexus of space-time.

The Alamo Drafthouse in Austin has a 70mm print of 2001, and I was lucky
enough to get a ticket to a viewing two summers ago. They even kept the
intermission in place for a 151 minute film, a length today that would barely
raise an eyebrow (LotR - The Two Towers is 179 minutes).
It really is a mind-blowing film. He changed the design language for space
from jump-suits and ray-guns to something cleaner and more logical. As well as
spaceship design, clothing and the space suits. And reinforced IBM's design
language as _the_ way a computer should look (even the non-homicidal ones).

The Big Book of Bitcoin - An introduction - alphydan
http://alvarofeito.com/articles/the-big-book-of-bitcoin/#.UUxY7MrTvGw.hackernews
======
willholloway
This is a great intro to bitcoin. It made me feel more optimistic about the
prospects of the currency.
It highlights many of the risks and benefits but misses out on what I think is
the Achilles' heel of bitcoin, the ability for sovereigns to shut down the
exchanges.
Without the ability to convert bitcoin to fiat easily, the currency loses its
usefulness as a proxy for fiat currency. Does anyone have a convincing
argument for how the exchanges are not vulnerable?
~~~
meta-coder
The situation is like the chicken-and-egg dilemma.
Definition 1: 'Good producer' is a producer that accepts bitcoins.
Definition 2: If all the good producers together produce all that you need,
then the number of producers is 'enough'.
Definition 3: 'Ideal state' is when enough good producers exist.
Theorem 1: A producer will accept bitcoins if either of the following is true:
i. Ideal state has been attained. ii. There exists exchanges that trade you
physical currency against bitcoins.
Observation: Once we are in the ideal state, we no longer need to have
bitcoins converted to physical currency. So we don't need the exchanges to
exist forever. We need exchanges only till enough producers have started
accepting bitcoins.
~~~
aneth4
Except the only ideal state is when you can buy anything in the world, not
just "enough."
The great thing about good currencies is they can be exchanged for almost any
currency and therefor can be used to purchase almost any good or service that
is for sale.

I'm a non-math guy who's trying to write a legal treatise on the use of
bitcoin, and I'd like to give some background on how it works to my readers.
Can anyone help?

"Bitcoin is obviously not the solution to these issues, nor will it be a key
enabler to crime. It is just a currency with some interesting features on top:
peer-to-peer, security, public transactions and potential anonymity."
Not a key enabler, but I think criminals would definitely appreciate a hardly
traceable and potentially anonymous currency, don't you think?
It's not an opinion unfortunately, there is already evidence floating around
that they are using it or that they are very interested about it.
Because of this I don't think bitcoin should replace a national currency
anytime soon, can you convince me otherwise?
~~~
alphydan
I can't. I think criminals will find their way with Bitcoin or without it.
It's easy to fall for the easy argument: "the standard banking/monetary system
is even worse, so bitcoin is ok". As a small example HSBC was considered too
big to jail (they laundered last year about twice the size of the Bitcoin
Economy, helping criminals, drug lords, etc), and only got a slap on the hand
(a $1.8bn fine). The powerful can launder their money, do tax evasion, use tax
havens ... now it's available to all technicaly skilled ones (good or bad?).
Drugs sold on silk road were evaluated (<http://arxiv.org/abs/1207.7139>) last
year to about $14m/year ... a good 20% - 30% of the bitcoin Economy, so yes
it's looking pretty tainted so far. I would however highlight one innovative
point: If you slip (leave any trace, don't use TOR, use a physical address,
leave your IP), the community can track you down! And I think it will happen.
Because ledgers are public, you can make algorithmic criminal enforcement
:)(for those criminals or corrupt politicians who are not careful enough)
~~~
gregpilling
Well said.
I also think criminals will avoid it like the plague. Bitcoin could
conceivably tell law enforcement everywhere you received money from and
everywhere you spent it. I realize it is one long number transacting with
another long number, but law enforcement have computers too, and they have
time on their side. Using bitcoins could be like leaving DNA on the scene of
the crime - probably not a good idea if you want to get away with whatever you
are doing.
~~~
gcv
If I understand the idea correctly, using a different key pair for every
transaction should help mask user histories. Not sure if this is easy in
practice.

I just got to wondering, how would charging for a monthly service work in
bitcoin? A user can't just give you an account number and say bill me $X every
month, right?
Any thoughts on how to design such a system?

melvinmt
Technical details aside, I don't want to be tied into paying for a service in
a currency that fluctuates 30-50% a month. I think that's by far the biggest
problem bitcoin currently has.

DavidSJ
A few minor issues: a b is a bit, a B is a byte.
A satoshi (not satochi) is 0.00000001 BTC, not 0.000000001 BTC.
Not sure where the $6,000/BTC comes from for $80b in annual transactions per
10m BTC, but consider velocity of money. A BTC can be spent multiple times in
one year. Also consider that monetary base (raw currency) is not the same as a
credit account, but you can spend either.
So in practice, you might only need 0.1 BTC per 1 BTC in annual transactions.
~~~
alphydan
Good points about velocity and monetary base. "satochi" spelling and decimals
corrected. Thanks. The $6000 is just an order of magnitude >>>(80/12)*1000.
Too many unknowns for anything beyond guesstimates: What percentage of the
currency is hoarded by then (1/2? 1/3? 3/4?). How many bitcoins are lost
forever? As you point out velocity, or even limits on transaction speed from
block-size ...
~~~
DavidSJ
Even for a wild guess I think you're off by at least an order of magnitude if
you don't take into account velocity (typical dollar is spent four times per
year; edit: and bitcoin, as a digital currency, is likely to have higher
velocity) and the different types of money (monetary base is maybe one fifth
of total money supply).
Note also that your math involves 12m BTC but your page says 10m.
~~~
alphydan
I may very well be off by a factor of 10. Agreed. But what is your estimate?
and what exactly would M2,M3 and M4 be?
Let's assume 12m has been mined, 1m has been lost forever, 8m are hoarded, and
a velocity of 10. You then have 30m bitcoins in transactions but 3m bitcoins
circulating. In this case my estimate is off by a factor of 2 - 2.5 (but it
could be 10, sure). But What if it doesn't take over half of paypal's
transactions, but rather 4 times all of paypal's transactions? That's why I
think any estimate is pretty hopeless. A good order of magnitude is ... if it
reaches paypal scale it will be in the thousands.
Since there is no fractional reserve banking (yet, anyway) in the bitcoin
economy, I don't see how the monetary base can be 1/5th of the money supply
(but I might be missing something).

xhrpost
Is the part about it costing $25,000 Million to "trick the network" true any
more, given the advent of ASICs into the mining arena? User 67117 on BTC Guild
is currently processing 6,348.98 GH/s, or roughly 10% of the entire mining
network. While not cheap, it appears it could be relatively affordable to hit
the 50% mark.
~~~
alphydan
As of today, you can't buy the ASICs because they don't exist, so I guess it's
true (plus minus a lot of millions as it is a rough estimate). But it will be
a lot cheaper very soon for a brief period of time before miners up the arms
race [-- see reply below for clarification --]
~~~
xhrpost
So how is this one user mining 10% of the network?

asicminer-now-at-2-ths/)
~~~
waterlesscloud
My understanding (and it could be wrong) is that ASICMiner has made their own
asics for their own use. They are not selling them.
Their business model is that they have a sub-pool in a larger mining pool, and
they financed their operation by selling shares (denominated in Bitcoin). The
shares pay out weekly dividends, based on the awards the mining pool provides
to them.
There's a couple (very, very tiny) bitcoin denominated stock exchanges, and on
some of them you can buy ASICMiner "passthroughs". These represent shares in
ASICMiner that are controlled in large blocks by an individual. That
individual passes through the dividends to the passthrough shareholders, minus
a small management fee.
It's an elaborate system, but I guess money finds a way, even when it's
bitcoin.
~~~
mrb
That is correct. ASICMINER went through an informal IPO, selling at the time
the equivalent of $200k or so of shares. With these funds plus the project's
creators own investments, they designed a custom 130nm ASIC.
<http://bitcoinmagazine.com/asicminer-starts-hashing/>

tmflannery
The article talks about crowd processing eliminating falsified balances, but
it doesn't go into some exchanges getting hacked. Hasn't that been a security
concern? Haven't people lost money that way? I know my credit card numbers can
get stolen, is that the right comparison? Do exchanges just make you whole?

D3 is awesome but I've always felt it is more suitable for complex
visualizations. For simple stuff like line graph etc. Existing graphing
libraries are pretty cool. Anyone using it for common visualizations like line
chart or pie chart?
~~~
louischatriot
What I like in d3 is that it leaves completely free to do whatever you want,
be it simple bar charts or complicated stuff. I don't like integrative
libraries that don't allow you to make your graphs evolve.
I used it to build animated line charts but those are a bit more complex (you
have to use SVG paths with Bezier curves which are a pain to calculate ...)
------
cdomigan
Pfft. I can Build An Animated Chart In 1 Line Of Code With
DoesEverythingForYou.js
~~~
louischatriot
Of course, but the point here is that d3.js really is not
"doeseverythingforyou.js" : it only takes care of the "boring" stuff
(manipulating DOM, binding data) and lets you do whatever you imagine. So it's
more like "build this chart writing only the 19 lines of javascript that
matter".

Rust 0.8 released - steveklabnik
https://mail.mozilla.org/pipermail/rust-dev/2013-September/005804.html
======
chrismorgan
If you were wanting to use Rust but also wanted to use HTTP (client _or_
server), I've got [https://github.com/chris-morgan/rust-
http](https://github.com/chris-morgan/rust-http) which has rapidly become the
_de facto_ HTTP library (although it started after Rust 0.7 was released).
It's far from complete—but that's an opportunity for you to join in, if you
want.
~~~
erkose
"far from complete" and "de facto HTTP library" doesn't say much for rust.
~~~
chrismorgan
It's good enough that the Servo team decided to use its client (and now do),
but the approach I've taken (implementing the HTTP spec thoroughly, putting
Rust's type system to good use) will take quite a long time before it's
_really_ polished (e.g. we must implement types for every type of header,
rather than just using strings and leaving it to users to interpret them
[often incorrectly]). It's still a little experimental, but it's the only
really serious HTTP library there is for Rust out there.
Just wait until it's done. It will be a _really great_ HTTP library.
~~~
chamakits
I haven't taken a look at your library, but as a developer that has always
wondered "Why use strings for these things that could be enums, contants, or
types?" in API's, I appreciate your effort and your thoroughness.
~~~
mbreese
The answer is because that's what's in the spec. For HTTP, it's probably a
mistake to hardcode header types. They are defined as key/value pairs of
strings in the spec. There are a few keys that are specified, but how they
actually work in practice (upper? lower? quoted?) is difficult to predict.
There are just too many variations. So you end up with proper types for the
most common ones, and then throw the extras into a separate "others" type.
Which is great, except that now you have two places to check for things.
In this case (HTTP), it's easier (and more correct) to just leave them as
stings. The general principle with network protocols is to be strict in what
you send, and forgiving in what you receive.
~~~
chrismorgan
The headers are data, not text. Somewhere along the way you'll need to
interpret them; doing a good job of that at the system boundary is the only
_sensible_ approach. (It's not the approach the majority of tools have taken,
but it _is_ the only sensible approach). If it gets into the system as text,
people will start pulling it apart in even worse and less consistent ways.
I agree with you that the parse behaviour for HTTP headers is poorly defined.
That's something I'll be wrestling with all the time.
Supported headers will be in one place and uncommon extension headers in
another. Such, alas, is life. But really, the only time when I would expect
this to cause any trouble at all is when new headers are added. Compare it
with things like the CGI standard and how it handles headers and you'll
realise it's not such a bad system.
I should make it quite clear that the specs are (unfortunately) only a
starting point for rust-http. Where there are deviations, more leniency may be
added. But it'll be added thoroughly and properly.
------
devx
If they make their next-gen browser using Rust, I hope they make it 64-bit-
_only_ , and optimize it as much as possible for x64 and ARMv8. None of that
"support back to Windows XP!" stuff. It wouldn't be necessary (will still have
Firefox a few years longer for that), and it would just hold them back in
terms development time, maintenance, performance and security.
Then it would be not just great PR for their "highly-optimized no legacy cruft
64-bit browser", but would also give people a reason to switch from _Firefox_
to it. It would also give Mozilla an excuse to not make a 64-bit Firefox
anymore.
I assume it's going to take them at least 2-3 years to do it (if they ever
plan to release it), and by then Microsoft will probably release a 64-bit only
Windows 9, iOS will be 64-only, too (probably not relevant to Mozilla, but
could be in the future), and at least half of all Android smartphone users
will have ARMv8-based devices.
Mozilla should take full advantage of this, and really push for performance
(and security), and they should only make it available from Android 5.0
(probably the first 64-bit Android version) and Windows 7 x64. Support for
Linux kernel should probably start with no lower than 3.10 LTS (contains all
the ARMv8 support).
~~~
marshray
Note that Windows XP 64 bit was a thing. :-)
Very few of today's apps actually benefit from having more than 3GB of address
space. Nothing on my desktop PC is using more than 300MB at the moment. All
else being equal, 32 bits will be more efficient, particularly on portable
devices which tend to have far less memory bandwidth.
~~~
jfb
All other things are not equal, however.
~~~
marshray
True, there can be address space fragmentation issues on large 32-bit
processes.
What else did you have in mind?
~~~
Tuna-Fish
The extra registers and other advancements in instruction sets help a lot.
x86 has some enchancements, but if you think that 64-bit is bad for mobile, I
strongly suggest looking at the A7 32 vs 64 benchmarks. (
[http://anandtech.com/show/7335/the-
iphone-5s-review/4](http://anandtech.com/show/7335/the-iphone-5s-review/4) )
Of course, the performance gains have really nothing to do with 64-bit
addressing alone, but ARM took the opportunity to almost completely redesign
the ISA, and A64 is in general a better and faster ISA than A32. So all else
is not equal.
~~~
sanxiyn
I actually find this 64-bit-has-better-ISA-than-32-bit situation annoying. I
would like to have better ISA, without making pointers larger. There is
x32([https://sites.google.com/site/x32abi/](https://sites.google.com/site/x32abi/)),
will there be something similar for ARM?
------
mcpherrinm
Remember that Rust is still a rapidly changing language, and releases have
very little connotation of stability, support, or any other guarantees.
They're released on a schedule, not by features. They're useful to be able to
refer to periods of time in Rust's rapidly changing lifetime, but not much
beyond that.
~~~
ternaryoperator
This! I so want to play with Rust. I want to explore it over programs that are
several thousand lines long, so I can get a real flavor for it. But the rate
of change especially to important elements of the language is still too great.
I don't want to rewrite the code to stay abreast of revs.
Not a critique by any means--I admire the language and the work being done.
More of a wish that the core language syntax would settle down soon.
~~~
steveklabnik
To be clear, the syntax changes in this release were very minor. It's mostly
the standard library and runtime that are changing at this time.
That doesn't mean that your sentiment is wrong; if you don't want to be
keeping up with the langauge's changes, certainly don't write projects in
Rust. That said, there are more libraries than you'd expect, including a few
that are several thousands of lines.

Yeah, _only_ the _entire_ for loop syntax changed. ;)

Rust is pretty good as a language but things are still changing a lot,
especially on the library side.
I did a project in Rust as a learning exercise. The language is easy to pick
and I was able to hit the ground running from the start. The major learning
hurdle I think is the memory model, which is different from most languages out
there.
Here's my first Rust project after two weeks of on and off hacking. It's a
Memcached client library implementing the Memcached protocols in pure Rust.

saosebastiao
1) I think I've had 4 different people try to explain lifetimes to me and I
still don't think I understand.
2) The use of pointer dereferencing in closures is still quite confusing to
me. For example, from the tutorial:
let square = |x: int| -> uint { (x * x) as uint };
no pointer dereferencing, yet:
[1, 2, 3].map(|x| if *x > max { max = *x });
uses pointer dereferencing. I can't figure out any rhyme or reason behind it.
3) How do you create traits that can be automatically derived? How do you
implement a default method?
4) How do you create and use macros, and in what situations are they the
appropriate solution over other forms? (I'm used to using macros in lispy
languages, but using them as pervasively in other languages seems to be a form
of code smell).
~~~
pitterpatter
Maybe this will be useful to understanding lifetimes: [http://static.rust-
lang.org/doc/0.8/tutorial-borrowed-ptr.ht...](http://static.rust-
lang.org/doc/0.8/tutorial-borrowed-ptr.html)
As for the pointer dereferencing, perhaps putting the type there will make it
clearer:
[1, 2, 3].map(|x: &int| if *x > max { max = *x });
Now you can see that x isn't actually an int but a reference to one.
As for automatically derived traits, those are actually slightly more powerful
macros implemented in the compiler itself. You can see it at
rust/src/libsyntax/ext/*.
For default methods, you just put the code you want in the trait itself. Like
so:
trait Animal {
fn sound(&self) -> ~str;
fn make_sound(&self) {
println(self.sound());
}
}
The make_sound method is what's called a default method. If you implemented
that trait, at the very least you would have to define the sound method and if
you wanted to, you could override the default make_sound method.
Macros are actually created with another macro called macro_rules. I'll defer
to the tutorial for them: [http://static.rust-lang.org/doc/0.8/tutorial-
macros.html](http://static.rust-lang.org/doc/0.8/tutorial-macros.html)

Is there an actively developed web framework for Rust, kind of like Revel for
Go?
I have a toy web project I'm starting. Would love to play with Rust.
~~~
steveklabnik
Not yet. As chrismorgan points out above, the http library is still being
developed, once it's more stable, web frameworks can be built on top of that.
~~~
zokier
Wouldn't web frameworks be using something like fastcgi rather than raw http?
~~~
chrismorgan
Why? FastCGI is slow. Controlling the entire HTTP stack is fast, and makes
deployment much easier (only one piece of software to configure, not two or
three).

portmanteaufu
Congrats on all the progress, guys! I'm really looking forward to getting to
work with Rust. I have a couple of questions:
Is the new fixed-stack FFI arrangement the end goal, or is it a stepping stone
to a different system? It seems as though always using a big, fixed stack
would cause performance/memory issues. Could the compiler detect which Rust
fn's call extern "C" functions so I don't have to write annotations? Thanks!
~~~
kibwen
Fixed-stack is not the end goal. The intent is to migrate back towards small,
growable stacks.
There were long discussions over how "smart" the extern stack-size strategy
should be. The current arrangement is, as ever, a compromise. In practice,
most people writing bindings to C from Rust will wrap the C call into a very
thin wrapper function whose job is to handle type conversions and managing the
necessary `unsafe` bits. The hope is that putting the annotation on these
wrapper functions won't be very onerous, with the result that any Rust code
that calls the wrapper functions won't ever have to bothered with remembering
the annotations.
~~~
portmanteaufu
Makes sense, thanks! As an outsider it can be tricky to know which things in
the release notes are "This feature is ready" vs "This is simply the present
state of things."
~~~
steveklabnik
Rust is basically entirely 'this is simply the present state of things.' :)
~~~
chrismorgan
Plus there's also rather a lot of non-codified knowledge about what's
happening and going to happen. But if you pay much attention to the mailing

Why I've built an alternative to Github - fnando
http://blog.codeplane.com/why-ive-built-an-alternative-to-github.html
======
mechanical_fish
I don't understand this use case:
_These projects are mainly side projects, or small freelance jobs I've done
through the years, and I want to save them for posterity; who knows when I'll
need them, right?_
My solution to this problem is called _tar_. Just clone the Git repos to /tmp,
tar up the results, and push the tarball to S3. Done. Archived for posterity
for a few cents per month.
This isn't SVN anymore: It doesn't take special voodoo to host a repo. If
nobody needs to push or pull from a repo, tar it up and archive it. If _one_
person needs to push and pull from a repo, store it on that person's local
hard drive (with backups, of course). If _two_ people need to push and pull
from a repo... Well, this is no longer an archive for posterity, this is an
active project, and can the team really not afford to pay Github something
like $5 per month per repo?
~~~
jpeterson
I imagine part of the use case is "quickly and easily getting back to a
snippet within one of those old files", in which case the tarball and archive
method won't really work.
~~~
bruceboughton
He's talking about tarring a local git repository. You can still use all the
git history stuff, you're just backing up using tar rather than via git
push/pull.

micheljansen
While I do agree that Github leaves space for a model like this, I think the
value of Github is that it offers a great community and awesome toolset
(online and offline). Then I read this:
"I also wanted to do almost everything from my terminal, so I built a CLI,
that you can use to manage repositories, public keys and collaborators. For
daily usage, you probably won't have to go to our web interface ever again,
and that's awesome!"
And I think "that's what I have with Gitosis on my VPS" (Gitosis uses git to
manage user accounts and keys, so it pretty much doesn't get simpler than
that). Companies pay for Github for the tools, developers who use CLI are
probably not that interested in forking $9 a month for something they already
have. Just my two cents, but I wish you the best of luck :)
~~~
fnando
Yeah! One can always set up the whole thing, but for small shops and
freelancers it makes no sense to manage something like this.
Maybe for hackers like us... ;)

I just use bitbucket.org + Mercurial. More than enough for personal projects,
or more, given that it's unlimited. The only limit is amount of users.
Switching to Hg was a bit of work, but I've actually learned to like it more
than Git. Really though, it's the same kind of thing and I just use both. So I
ended up at bitbucket for the same reasons OP built a new site.
My way was quicker though.
~~~
StavrosK
I use github for the network effects, but how does hg compare to git, speed-
wise? I switched to git from bzr because bzr felt awesomely slow, although git
is a real pain to use, even when you're familiar with it.
I understand that bzr and hg are almost identical, command-wise, but hg is
about as fast as git, is that correct? What my workflow consists of is
diffs/statuses/commits/pushes/pulls in projects with working trees of a few MB
at most.
~~~
eropple
Hg is marginally slower, but not so you'd really notice. If you're crunching
20,000-line files on a regular basis it might be a concern. On repos of that
size, I doubt you'd notice.
Git is a great tool for what it was built for and the group of users it was
intended for--that is, rapid, tons-of-merges-and-pulls development on a
gigantic codebase, for users for whom it is acceptable for man pages to serve
as reminders rather than instructions. However, I appreciate the additional
attention paid to tooling and user-friendliness in Mercurial-land that make it
more pleasant for me to use.
~~~
StavrosK
The fact that all the tools can push to github make it easy to switch, which I
just might do again. bzr was great, except for the fact that it just doesn't
have that much traction...
~~~
eropple
I found bzr to be much as you described it - like hg, but slower. Nothing
objectionable about the workflow (though the tools on Windows were very poor,
I wasn't using Windows much at the time), just the perf on a particularly
large chunk of code.

You can set something like this up on any VPS with gitolite
(<https://github.com/sitaramc/gitolite>) pretty easily. gitolite lets you set
up very fine-grained per-user/repo/branch permissions, manage your users' SSH
keys, and gives you nice clean [email protected]:repo-name access to your
remotes.
I've done this for myself with a $48/year VPS from prgmr.com specifically
because I needed more private repos than Github could offer (my setup
instructions are here: <https://gist.github.com/1035834>).
Granted, if codeplane.com existed six months ago I probably wouldn't have
bothered with gitolite. It appears they do nice things for you like backups.

Gitosis does not have as fine grained control as gitolite nor is it as well
documented (config file errors are hard to debug), but it works well within
its limitations. Both are now available as Debian/Ubuntu packages (gitolite
was not when I started using gitosis). The other obvious difference is that
gitolite is written in Perl and gitosis is written in Python. This should be a
superficial difference, but sometimes the world isn't rational.

Gitolite is a fork of Gitosis that has been both improved and actively
maintained. It even has a script to automate converting your old gitosis.conf
to the new format.

I run a services company. I am near my limit for 125 private projects with
mega plan.
I have 100+ private repositories,with about 100 collaborators(many are my
clients) and consume just 2.3 gb and pay 100$/month, about 15-20 of the
projects are live/active, others are projects which have been delivered or on
hold.
Organization as a concept was brought pretty recently on github, my account
dates 2008, charging double for just that is not attractive.
I love github, they are coming with awesome features, but in terms of certain
features many service firms need, a way to archive the project not counting
them for active projects. github is lacking. instead of doubling the service
plan every 6-9 months I am willing to give the competing git hosting services
a try
------

From another perspective, Heroku has unlimited free git hosting that happens

Github's pricing model really is a painpoint for little consulting shops. We
drive next to no traffic and storage on there, but we do a few projects every
quarter. Haven't quite outgrown our paid plan yet, but we will in a bit.
Just wish Github would revise their pricing to support peeps like us, I hate
to use different interfaces. May choose to just archive things to codeplane
until then, keeping things we are actively developing on github.
~~~
trustfundbaby
Try unfuddle, their hosting includes both svn and git ... doesn't have most of

Same feature set as <http://repositoryhosting.com> with a higher price point
(they're at $6/month now for 2GB). They don't have a CLI or anything as far as
I know but they do offer more storage space at $1/GB/month which is pretty
nice if you just need a little extra.

arturadib
I think CodePlane is very cool, but it seems to solve a different problem than
the one advertised on the blog.
To save my repos "for posterity" on Github without incurring a $100/month
bill, I simply create a master repo (say old-projects/) with all my unused
repos in it.
On the other hand CodePlane seems to be a great solution for collaborative
work on lots of private repos. This can save big bucks.
I love to see projects like this. I hope it gains some traction and forces
Github to change their business model to a more manageable per-GB price.
~~~
sant0sk1
The one-repo-for-old-projects solution works in some cases, but not really for
mine. As a contract developer I often have projects that are under active
development for a few months and then go into "maintenance mode". In this case
I want separate repos for when maintenance needs to happen. Otherwise that one
repo is a mess.
I believe this is the kind of problem that CodePlane solves. And I agree with
you that its great to see projects like this present competition and make
GitHub better in the long run.
~~~
arturadib
It's a hack of course, but if the changes are really that occasional, the pain
is negligible: all you need to do is to commit twice for every project change
(once for a sub-directory containing the project repo, once for the root
repo).
If a project becomes active again, simply take it out of the master repo and
push it as a new repo.
It's really not that bad. But then again, things change if you have
collaborators...

grandalf
This is a very desirable use case. For those who don't get it, I'd say the
following:
\- it's nice to use git for all the small side projects one creates, but
putting all of them on github is crazy expensive if you like keeping your
musings private (though not necessarily b/c you're committed to a closed
source ideology :)
\- the cost factor creates an incentive to misuse git (not using submodules
where appropriate) just to save money.
\- There are a lot of awesome Git UI programs that run locally on my laptop,
gitk is one.
\- FWIW his fills the niche between github and gist.

Private code sharing. You have to install something like gitolite (see my
other comment) to do private code sharing with git on a VPS, or you'd have to
create a system-level user for every person you want to share code with.
~~~

Webfaction actually allows you to create a git repo with web interface that
can be shared privately.
It is one of their "one-click" installations and I have been pretty happy with
it for my limited use.

xbryanx
I am currently frustrated with Github's private repository hosting plans. When
I switched from SVN to Git, what was initially one repository became six,
because of Git's "you can't checkout part of a repo" philosophy. So now, I
have to buy a fairly expensive plan even though my usage is pretty small.
Cheers, to you for adding some competition to the marketplace. I hope it
provides some pricing pressure on Github one of these days.

I find $12 a month to be really cheap.

The UI at Assembla is awkward to work with. I participated in a project that
used Assembla, and I kept getting a flood of emails attached to tasks and
revisions that I didn't want to follow.
~~~
Revisor
You can change the email notifications, BUT:
I couldn't find it for 5 minutes!
A similar thing happened to me a few weeks ago when I was looking for a way to
add more repositories to a project. Luckily I got an answer quickly on their
support forum (and yes, it was there).
So yes, the UI and information hierarchy is lacking, but ultimately it can do
a lot of things.
(For future reference, you can change the settings under Stream - Email
Notifications).

I hadn't gotten around to commenting, and I'm glad it took me a while, because
while I first went to Codeplane and set up a trial account, pushed my Github
private repos therem and downgraded my account from a paid to an unpaid
account — thereby netting myself a free cheap beer a month — I went on to read
some of the comments here, set up gitosis, and am now free of any sort of paid
git hosting fees beyond my existing Linode virtualized server — upgrading my
free monthly drink from a PBR to a Hendrick's martini.

I can say that's is pretty safe. Backup is not an issue: copies of all
repositories are stored on S3, CloudFiles and Linode's backup solution. People
can't access your repos, unless you allow them to.

flocial
I've always wondered about this. The real expenses are disk space and
bandwidth. I don't understand how they can't just provide a space-based plan
(oh yeah, that would cut into high margins).
It's a wonderful service and they've done so much to keep many open source
projects from stagnating. They outshine SourceForge and Google Code by a large
margin. Still, if BitBucket was git, I might migrate my stuff.
The thing is "social coding" isn't that big of a plus for your own private
stuff. I definitely see value in a service like this.

for updated-infrequently-if-ever repos, github's pricing doesn't make a lot of
sense. i have plenty of small, one-off repos i'd love to back up on github but
it doesn't make sense for me to upgrade plans for them.
i just back up to multiple boxes, but i can understand why someone would want
something centralized and specific.

I agree. My small company has many 1-2 week dev efforts that we'd like to have

The title of the page at www.codeplane.com is "Unlimited private Git hosting",
yet it appears that you are limited to 2GB of repositories for your $9/month.
How is this unlimited? Are there other plans that you can sign up for? If so
they seem impossible to find on the site.

jimktrains2
I think he's referring to the absence of a limit on the actual number of
repos, which is only bound by the space given. If you can git 1000 repos in
there, good for you, he doesn't care.
Granted, something like "2GB private git hosting" might be more accurate.

Fog Creek has a product called Kiln, which is like Github, but is based on

M1573RMU74710N
I don't think anybody is "complaining about GitHub's prices" per se...at least
not the way you are implying. That is, I don't think anyone is saying GitHub
is greedy, or not worth it ever or something like that....
However, the fact of the matter is they have a particular pricing plan, and
that pricing plan is such that for certain people it becomes not worth it.
When you go to a fast food place, they generally offer you varying sizes of
soda.
For most people that's fine....but for some people their needs may fall JUST
in between two sizes...for example they want more soda than a medium, but they
don't really need a large.
So they start buying a large...because that's a reasonable compromise.
Sure, the large may be a _very good deal_ , but that's completely besides the
point. It's more soda than they really need, and they are wasting money by
buying it.
When someone offers a size of soda that happens to fit their needs exactly,
there's no reason they shouldn't switch to that. If their needs change they
can always go back to their old size, or even a newer one.
Or to pick another soda analogy, imagine that the fast food place only charges
for the soda cup. It's a dollar a cup for everyone. This is a _GREAT_ deal for
most people...they come in pay a dollar and get a cup of soda, with free
refills. The fast food place does alright because it all balances out in the
end, the people who drink a little soda subsidize the ones who drink a lot.
Even people who only drink one cup of soda get a reasonable deal.
Now imagine you come in with 100 kids who only need a thimble-full of soda
each (for the sake of argument). You're paying 100$ for the amount of soda
everyone else is paying 1$ for! Overall, the pricing plan is reasonable...but
for certain people it falls apart.
Why should those people go with a deal that doesn't work for them? It's better
all around for them to find a better fit.
The fact that github is awesome and a great deal is completely irrelevant re
the issue at hand. The point is some people don't need all the github
awesomeness, they just want somewhere to stick their code.
If that's all you need, there's no reason at all not to go with a cheaper
option.
That's not to say that the cheaper option is this guy's service....it could be
any number of things. For some people this codeplane is a good fit, for
others...not.
~~~
cool-RR
_"Sure, the large may be a very good deal, but that's completely besides the
point. It's more soda than they really need, and they are wasting money by
buying it."_
You actually put your finger right on the fallacy. It _feels_ that you're
wasting money by buying a GitHub account with 100 private repos when your
repos are largely inactive. But the way to make smart economic decisions is
not by measuring hypothetical waste (i.e. how much of the account you are
using) but by comparing the options side by side. You pay more for GitHub,
yes, and you pay for stuff you might not use, but if it saves you a few hours
per month then it's a better choice than going for a service like CodePlane.
~~~
M1573RMU74710N
>, but if it saves you a few hours per month then it's a better choice than
going for a service like CodePlane.
...and that's the hole in your reasoning. That is not a forgone conclusion at
all...in fact it's a non-sequiter.
In the analogy these people aren't getting ANYTHING for paying the 1$ per cup
(vs paying 50 cents for the actual soda used)...there is a theoretical benefit
of free refills, or it being a reasonable price for the cup of soda...and for
the people who use it, it's great.
...but the __whole entire premise of this discussion __is that for some people
that's no benefit at all since they're not using it.
We've already eliminated all the people who are getting their money's worth
out of Github, that's the premise of the conversation....we're talking about a
service that is designed to cater to people for whom Github's pricing plan
doesn't work for their needs.
Additionally, to argue that these people don't exist is a specious argument. I
think it's an incredibly dubious proposition that there is _ANY_ service which
precisely fits the needs of it's entire target market.
>. But the way to make smart economic decisions is not by measuring
hypothetical waste (i.e. how much of the account you are using) but by
comparing the options side by side
Yes, precisely.
You make smart decision by weighing your own personal needs against your
options. Everyone has different needs, and while Github works for many people,
it does not work for everyone.
Again, I'm not prepared to say codeplane represents a solution for all these
people...many will simply go to bit-bucket, handle it themselves, etc... but I
think it works for at least some of them.
------

One plan, one price seems like a good tagline, but what if a user needs more

eventually will have more plans, or will charge per GB?

I configured a Git server on my EC2 micro-instance and just use that.

going back to GitHub, as I'm still a happy user of their free account. GitHub
rocks.
Sure, competition is good, but I don't get what codeplane.com is offering,

a hassle?
Assuming you have ssh access (compacted for clarity):

Am I missing something?
EDIT: mkdir superfluous

That doesn't handle the multi-user authentication/authorisation.

Yes it does, however it doesn't provide granularity for multiple users of the
same server, and unless you go for vanilla could be troublesome to customize
through something like pam. I simply commented on the non-issue with creating
private repositories.
A service like this is nice if you don't have the ability or time to setup
your own environments, but in my opinion could be risking a very slim user
scenario.

If your developers are spending more than 5 minutes a month managing,

Lawyer who argued for Internet sales taxes admits he doesn't pay them - gnicholas
https://medium.com/@nicklum/the-attorney-who-convinced-the-supreme-court-to-allow-internet-sales-taxes-just-admitted-that-hes-a7ef9ce8ae35
======
edbaskerville
I see this as a great argument for his side, actually. State governments need
to be able to enforce taxation at the time of the transaction, because it's
going to be impossible to collect otherwise. Without an effective collection
and enforcement mechanism, of course individuals won't go out of their way to
make extra payments! Even the tax lawyer arguing the case isn't going out of
his way to pay!
The question of whether states should be able to charge this tax in the first
place is another conversation. But if you accept that levying these taxes is
the right choice for society, there needs to be a viable collection mechanism.
~~~
gnicholas
Yeah good point, though probably one could make this point by showing
statistics about how much tax is due versus paid. I’m sure the numbers are
stark.
------
chrisbennet
While the implementation of the tax may be poor (expecting everyone selling
something on the internet to know the tax for 1000’s of addresses) it
certainly seems fair that the tax should be paid.
As a compromise, if the only the state tax was due, that would be something.
~~~
gnicholas
That does seem like a much fairer compromise. In the law at issue, a business
could be required to charge and remit taxes if they had just 200 transactions
with residents in the state. If this means compliance with dozens or hundreds
of county laws, that could be burdensome.
------
gnicholas
Note: I'm the author. I used to be a tax lawyer, before getting into the
startup life. Hopefully this piece appeals to non-lawyers and general-purpose
readers. Would love to hear comments from fellow HNers!

Reaching and re-engaging users on the mobile web - cjdulberger

This is pretty interesting. I remember some time ago Vox Media (who make The
Verge and Polygon along with Vox itself) declared that they were going web-
only:

It doesn't seem to have hurt them - but push notifications are probably the #1
feature that differentiates between webapps and native apps in a context like
this. I wonder if they'll take advantage.
(as with all things mobile web, this comes with the huge caveat that Apple
have no intention of doing this (despite having similar functionality on
desktop), and want to force everyone to use native apps, so it's unlikely to
be a complete solution any time soon)
~~~
sosborn
Personally I can't think of anything I want less than push notifications from
websites.
~~~
untog
Why, though? Or, put another way, why are push notifications from apps fine
when push notifications from web sites are not?
~~~
sosborn
Honestly the only notifications I care about are email, text messages and
phone calls. The rest can all go to hell. Again, this is just my personal
taste.
~~~
kinlan
I think that is fine. You can disable notifications and push completely, and
you can not accept the prompt if you don't want to go that far. We are trying
to be careful and make this opt-in only and clear to the user about the value
that they can get from it (if they choose it)
------
themodelplumber
This is cool to see. The other day a client with about zero technical
expertise told me she had won a grant to develop an app, then went on to
explain "it has to be a web app that can be used offline; it can't be a
regular app." I was pretty blown away and immediately offered to code it for
her, just because I'd much rather build and promote this kind of app. These
new Chromium features give me hope that it might be even easier to enhance web
apps across the board, in the future.
The downside (or frustrating side) with this project is that 1/4 of the grant
money is set aside for coding the web app, and while it's not a teeny sum, I'm
wondering just how much "app planning expertise" is being brought into the
game by whoever's getting the other 3/4.
~~~
karmelapple
You are part of that 3/4.
A proof of concept or mockup to verify that you've correctly captured
requirements? Sounds like planning to me.
Determining which technology stack is best, including building (to be clear, I
mean coding) some basic systems to test out if your assumptions about
performance and writing the pieces are correct? That's planning.
And so on.
Hours spent writing code are not mutually exclusive to hours spent planning
for the success of a software project.

It's kind of interesting to see Android, Chrome, and FirefoxOS all rushing
towards the same point, though from different directions.
Chrome is trying to "nativify" the browser, and making the browser a more
seamless part of navigating Android[0].
With FirefoxOS, the webapp is already native, and the goal is to browserify
the native OS (in other words, to make the operating system itself inside the
browser).
[0] I say Android specifically because this integration already goes much
deeper on Android than on iOS, simply because it can.

dublinben
It would be a significant step towards "reaching and re-engaging users" if
Google would make it possible to actually build a functional Chromium browser
for Android. Since they've completely abandoned the default AOSP browser in
favor of Chrome, there is no longer an up to date browser in AOSP.

My understanding is that there is a up to date Browser. The browser app has
always been built with a WebView and the latest WebView is pointing to almost
the tip of the development tree of Chromium.

Ask HN: How to prepare for an interview at a startup - mmackh
I've been contacted a few startups, who noticed the Open Source work I had done this year. They had requested to speak to me via phone to do an interview. What is the best way to prepare for such an interview?
Is there a resource that I could refer to?<p>The problem is that I have not had a formal CS education. I started coding ~1 year ago, and algorithms are not my strong suite. What kinds of questions do you like to ask and interviewee, what questions have you been asked?<p>Thanks!
======
nayefc
Here's what I've learned from talking to many startups:
1- First step would be a casual phone call to learn about each other. Make
sure you also learn about them and ask them tough questions about their
business. Both of you are interviewing each other: it's not just that they're
interviewing you. You don't want to suck up to a startup which you don't
believe in and end up signing an offer there.
2- If all goes well, most will schedule a Skype coding interview. You just
have to be prepared for those and that comes from experience (which you should
have from your open source experience). Don't pull an all-nighter learning
algorithms as they will almost certainly ask you a question that you couldn't
cover the night before. Hints: learn a dynamic interpreted and use it (Python,
Ruby etc...). I made the mistake of doing those in C in the beginning and got
stuck on the details / writing more code that they wanted in an hour long
interview. Some were impressed by my C skills, but that's not exactly what
they're testing here. Instead, most are looking at the bigger picture at this
point. i.e: they're seeing if you can you write a quick draft solution, and
optimize it later instead of seeing if you can properly allocate a struct in C
and place different struct types in one list. (Writing such an array takes
quite sometime --> they might be interested in how you'd design it instead of
actually doing it at this point).
3- Then comes the onsite interview. This is where you get to meet the team,
see the office, the location and experience a day at that startup. This is
very important. Your initial gut feeling is more important than you think. If
you don't feel comfortable, then do not sign an offer. You'll be at that
office at least 40 hours a week with the same people. You MUST be very
comfortable working with them.
Startups will often interview you for at least a few hours on different areas.
Design, coding, algorithms etc... Just do your best and the single thing that
they care about here is that you can actually write code that works and make
good decisions. It does not have to be perfect, but it has to work. They're
looking for someone who can build something roughly in a few hours, and then
explain the shortcomings (so that it can later be optimized). Someone who can
get things done, and perhaps become a leader later on. Since you've
contributed to open source, you should have absolutely no problem here.
Good luck!
------
relaunched
I'll let you in on a dirty little secret. While you find amazing brains at
startups, most of those guys spend 80%+ of their time writing non-sexy code.
As such, most startups are looking for people that can crank out well
organized, simple code, with outstanding test coverage and thorough
documentation.
The number of man-hours that are dedicated to the fancy stuff you read about
on HN is a very small percentage of the work that's being done. And, unless
you are brought in for your very specific expertise (which doesn't sound like
it's the case), you won't be getting to do the fancy stuff anyway; though,
you'll probably get an opportunity to learn from those who are.
Get a lot of sleep, make sure you keep in mind that they are looking for
someone who can work within a distributed code base and practice explaining
your thinking related to why you decided to do one thing over another. If you
do that, you'll be fine.
------
alphast0rm
If you have enough time I would highly recommend reading "Cracking the Coding
Interview" by Gayle Laakmann McDowell [1]. She does a very good job covering
all aspects of the interview process and the problems and solutions will most
definitely help you improve your algorithm and data structure skills.

I think you already have something to offer to them. That's why they contacted
you, so my suggestion would be to focus on what you have achieved until now
(open source projects). What you did, Why you did, what mistakes you made,
what you learned from them etc.

Show HN: Txr – Transfer files/directories to others with WebSocket streams - whatl3y
https://github.com/whatl3y/txr
======
cannedslime
Interresting but it really doesn't seem that simple. I usually just use rsync
whenever I need to move some stuff from one machine to the other.
I can't really take your word for it that you won't store any files,
furthermore that might not even be legal, depedending on your country you must
log transactions as a service provider.
What about SSL / encryption if you want to run the server your self, I took a
peek at the source code and it be nice if certificate was configurable through
the config files or ENV vars.
I think WebSockets should stay in the browser, but maybe that is just me being
pedantic.
~~~
whatl3y
Thanks for the feedback and recommendations. I agree I could add support for
an SSL cert to be used within the express server (today the Heroku dyno is
just using Let's Encrypt, which is abstracted from the app itself). I imagine
I could add this over a weekend that I have time in the near future.
> _Interresting but it really doesn 't seem that simple..._
Thanks for the feedback, but can you elaborate on how you feel it's not? I'm
not sure it could get any simpler to send files than `txr listen username` and
`txr send -u username -f filepath`, but I'm willing to listen. Maybe you mean
setting up the server isn't simple? Even that is as easy as `txr-server` from
the command line though with the package installed...
> _I can 't really take your word for it that you won't store any files..._
I appreciate this sentiment, but that's why the server component is included
in the package. If you don't trust the default server on Heroku (which is
primarily just for someone to quickly gain an understanding of how to use it,
not to actually use permanently moving forward), set up a server on your
machine or local network and use it instead :)
------
saganus
Interesting.
Would it make sense to pair this with WireGuard, to provide end-to-end
encrypted file transfer?
If we setup a WireGuard connections between two nodes, then run the server and
client through this link, it should work seamlessly, right?

Well fucking done. I wanted to build this ~5 years ago, but nodejs wasn't

Thanks! Yeah nodejs streams and async IO seemed like an ideal use case for
this type of tool, plus I wanted to have the easiest approach to passing files
between 2 people as possible (we use it at work all the time). Obv a lot has
happened in 5 years with nodejs, so I realize it was likely an order of
magnitude easier for me to get up-and-running in the last couple months with
this tool than it would've been for you 5 years ago haha.

Thanks for the heads up on the name clash (obviously never heard of the TXR

something that's easy to remember and makes sense (txr ~ transfer) and 2. the
NPM module name wasn't taken yet :)
I can change the name, but our projects are pretty much totally different and
I'm not trying to make any money off this tool so would prefer to just leave
it as is if it won't confuse too many people.
~~~
kazinator
> _obviously never heard_
In 2009, I didn't rely on what I heard of or hadn't heard of; I googled very
thoroughly before naming my project and its principal executable.
A name clash is a problem for any FOSS distro that builds both packages.
People don't directly choose and use everything that is installed in a distro.
A lot of is is pulled in by dependencies, for instance.

esthermun
The key to get _magic_ from Alexa long term will be get unsupervised learning
working on it, and then shared back across the entire Alexa user base. The
Brazilian real to USD is a great example. If by the 3rd try it gets the right
answer, it should notate that and equate the first 2 questions as similar
ones. I am surprised it couldn't catch the first 2. The word2vec output should
be fairly similar.
------

"In fact, I’ve had to avoid turning into ‘that guy’. I encourage my family to
use Alexa, but then I started admonishing them for not recalling the precise
sequence of words that unlocked the dusty tomb filled with knowledge of
exchange rates and types of currency."
Its interesting that in the last 30 years we've gone from unworkable text
adventure interfaces to the same unworkable interface in verbal form instead
of typed/read text. A lot of his story reads as a parody of an Infocom game
but spoken instead of typed.
------
jmcdonald-ut
I'll add my two cents on top of the author's. I have both the Amazon Echo and
the Amazon Tap. This article was spot on. I'm perhaps less forgiving than the
author. If Alexa can't answer a question on the first try I'll just give up.
When Alexa does answer a question or a request she usually does a phenomenal
job and it's just really cool. It really feels futuristic.
Echo is cool, it can be pretty useful, but it hasn't realized its full
potential yet.
I bought the Tap as a portable speaker to take with me on bike rides with
friends. Well I took it out the other day and the minute it lost WiFi
connection it just wouldn't work. I'm sure this was a problem on my end, but I
had already paired the devices and I wasn't going to spend time fiddling with
it while I was out with friends.
EDIT: Also it doesn't happen too often but Alexa has definitely accidentally
triggered. It even woke me up at 2 AM after the power went out temporarily to
tell me that it had no WiFi.
~~~
wccrawford
We've only had our Echo a couple weeks, but we've already found that
characters named Alexa in TV shows are a problem, and that at least once it
has responded to something that wasn't "Alexa" from the TV. So yeah, it
definitely has false positives.

Curious about OP's assertion on this as well. Only one I ever got was from a
company widely regarded as one of the best to work for in Atlanta (I ended up
not taking their offer so I can't say).
Unrelated to that -- one of my personal red flags is poor handling of the post
interview follow up. If a company drags their feet, gives conflicting signals
about next steps, etc., they probably are a mess.
~~~
pfooti
Speaking as someone with a cognitive science background (and yes, probably too
lazy to dig up specific references), I'll say that there exist a _lot_ of
poorly designed or poorly implemented tests of "intelligence". Even the
concept of intelligence is poorly defined, and lots of different measures are
just proxies. Even if the test is good and has some psychometric utility,
often giving the test is a giant pain to do well.
Even if the test is good, it's probably calibrated on WEIRD [0] subjects, so
is really only good as another kind of gatekeeper - you can probably use old-
school IQ tests as an excuse to reduce diversity. People who aren't WEIRD may
not do as well on these tests (even though they're just as "intelligent"
(parenthetically bracketing the ill-defined term for a moment)), so you have
your reason that you only hire white dudes. But that's a cynical extension of
logic there.
Most people, when approaching a psychometric test like one of intelligence or
personality make the first incorrect assumption that modern cognitive science
can actually form a construct like "personality type" or "intelligence" that's
stable across all cultures and norms, testable, and repeatable. That's just
not really true, and by and large what makes it to public consumption is
pseudo-science.
Diverting just a little bit here, but MBTI [1] is another good example of bad
use of psychometrics in business. There's about as much science supporting
Myers-Briggs tests as there is astrology, yet people still use MBTI for actual
decision making. Types aren't shown to be stable and they're not well-
clustered (meaning you can be a mix of introvert and extrovert, or show signs
of both depending on the day, context, mood). Zodiac Sign and MBTI Type should
only be used as pick-up lines in a bar. "Hey, babe, I'm an INTJ, so I'm not
going to say anything else."
There are good uses of psychometrics, but they're rare enough that I take any
reliance on any kind of psychometric during hiring as kind of a bad sign.

To be fair, I think that Raven's matrices probably get around this. If someone
explains the process to you, you don't actually need to be able to read to do
well on the test.
[https://en.wikipedia.org/wiki/Raven%27s_Progressive_Matrices](https://en.wikipedia.org/wiki/Raven%27s_Progressive_Matrices)
I do find it surprising that Raven's appears to be more susceptable to the
Flynn effect (people keep getting better at IQ tests, for an unknown reason).
Completely agreed on the MBTI, but its surprisingly difficult to convince
people that's its useful.
FWIW, I agree with most of what you said above, I was just pointing out a
counter-example. (Psychologist/psychometrician here).
~~~
pfooti
Yes, I agree that Raven's matrices are pretty good at measuring something in a
way that's not super-reliant on language. I'm not inherently opposed to the
notion of generalized intelligence as a construct either, I just think
measuring it is pretty tricky. The Flynn effect is another great example -
these instruments are nuanced, and it's important to really understand them in
order to interpret their results.
~~~
disgruntledphd2
Totally agree, I'm somewhat in sympathy with Shalizi's argument that g is just
the result of iterated factor analysis. That being said, done well, these
kinds of tests can provide useful data, especially if you're willing to
randomly hire to calibrate performance (which no one ever is, sadly).

salsakran
On some level, you never really know. People often behave differently when
interviewing (or trying to close you) than normally, let alone during
stressful periods.
The low hanging fruit here is:
* ALWAYS spend time with your future boss prior to accepting. Ideally try to spend as much time as you reasonably can. If this isn't possible push back pretty hard about why. Your direct manager is usually the biggest reason for your unhappiness at a job. "People don't leave jobs, they leave bosses" is a cliche for a reason.
* If people seem unhappy when you interview, don't assume it's just how they feel that day.
* Make sure you get a sense for the culture and whether you want to be part of it. If you're not into constant group activity, make sure you're not joining a hyper-intense "everyone hangs out with each other all the time" sort of place. Conversely if you're new in town, don't join a company where everyone is focused on working hyper efficiently and bouncing to go home to their families. Neither is right or wrong, but they can definitely be right or wrong for you.
* If you're connected, track down people who left the company and ask about your future boss. Were they hard to work with? Do people like them? If you have friends at the company (ideally, not reporting to your potential boss) ask about how your boss (and the department) is perceived by the rest of the company.
* Hit up linkedin and track down ex employees, ideally in the same job role. See where they ended up, and hit them up and ask why.
Good luck!
~~~
mundo
> ALWAYS spend time with your future boss prior to accepting.
Agreed, this is really effective albeit sadly not very common. You could say
something like, "Hey, I thought the interview went really well, but I'd like
to get together for an hour or so and just talk about software methodology and
about your company's products to see if we're on the same page," but what
you're really doing is interviewing your new boss. I don't think any good
hiring manager will turn down a request like this.

Homunculiheaded
Here's an interview question I always ask that has worked pretty well:
"If you could wave a wand and instantly change one thing about this
company/job/team, what would it be?"
This is similar to "what is wrong" but frames it in a positive light, so
people are more open and creative.
If the answer is anything about people "I wish communication was better", "It
would help if more people were on board for this project", "A change in
management wouldn't hurt, haha j/k" etc. That's a red flag.
If it's about non-people "I wish we didn't have so much legacy code", "I would
love it if we could get our testing setup better", "There are no good places
to get coffee around" that's a good sign that aren't major people problems.
If they can't think of one, that's a real cause for concern!
This is one of my favorite questions in general because what people wish for
tells a lot in many ways about the major problems, but without people begin
guarded. They're fantasizing not venting.

Can you explain why if it's anything about people, it's a red flag?
If anything, the social aspect of a job is equally or more important in my
search for a job.

Don't know wrt the OP, but I think people problems are much more difficult to
remedy than problems rooted in technology.

One basic way is to ask your interviewers what they like about their job.
You're going to get a positive response, but is it hand-wavy or specific? Is
it too specific, like they're just cherry-picking the one thing that keeps
them employed there? Is there light in their eyes or are they reading a
script?
Another way is to ask how decisions get made. Again, the specific answer is
going to probably be something pretty non-controversial, so look for the
subtleties.
Sometimes it's just obvious that it's too risky. I had one interview where the
hiring manager's boss managed to freeze him out of his own loop. I ran from
that one.
Also, you should be very skeptical if you felt like your interviews with
individual contributors were lukewarm or poor but you still get the offer.
That's very possibly a boss overriding flags from his team, or a team that's
deadened enough to not throw flags in the first place. If _you_ don't feel the
interview went well, trust your gut--might not be just your fault.
~~~
phonebanshee
Yes - and be very direct about this. Ask them "So why do you like this job?
Why is this a great place to work?" I've had someone pause, look at me and
tell me why it was a bad place and I should run away.
~~~
geoelectric
I had a hiring manager make me an attractive offer--and then in the next
breath tell me that he was planning on leaving the company, and I should run.
The gist was "my boss is watching so I have to make the offer, but he'll pop
into your office at 4PM and tell you you're working until 9PM on a regular
basis and otherwise interferes constantly. I've been unable to protect my team
from this. You can do better."
I sent him an explicit "thanks for the generous offer, but I've chosen to go
elsewhere after consideration" email so he had something to forward, thanked
him kindly privately, and ran like hell.
It's pretty amazing what you'll run into across a career. I've probably seen
more WTFs from the hiring side of the table than from the people I've
interviewed to hire.
------
throwawaytrain
I too have recently started a new job. I had a phone screen with the hiring
manager, then met with him for a two-hour 1-on-1 interview. Some time later I
was given the offer and accepted it.
I never met any of my future team members. I asked the hiring manager during
the interview to introduce me to the team, but he said this wasn't going to be
necessary.
Now, a few months into the job, I must say that I've never worked on any team
composed of such antisocial people. Pretty much no one here communicates
effectively. Cliques are demarcated along racial lines; there Chinese and
Indian groups don't really talk to each other, and don't "accept new members"
that don't speak their language.
This is the loneliest place I'd ever worked. What's surprising is that I never
thought I could be so lonely at work of all places.
So, lesson learned: if you aren't allowed to do a meet-and-greet with the team
before accepting an offer, don't even think about taking it!
~~~

This is pretty common among both racial groups.
And, if we're talking about the US, it was common across pretty much every
ethnic group that emigrated here.

In this context it's the fault of managers. Sure racial lines exist but such
hostility should not be allowed to exist by management.

Bosses can fall short in a lot of ways. While your intuitions might clue you
in to some failings, others are very difficult to spot. My advice would be:
\- Do the others on the team seem happy? Did you get to meet any during the
interview process? Do they seem to be happy to work there and comfortable in
the environment?
\- Does everyone seem to get quiet or smile officiously around the boss?
That's a big warning sign. It probably means the boss is a bit of a tyrant or
maintains an unhealthy power differential with the team. There is absolutely
no room for this kind of posturing in a startup.
\- Do you witness anyone coming to the boss for help with something? If so,
and if the boss responds in a positive way, it's a great sign. A good boss is
someone who is there to help everyone succeed and lend expertise when asked.
\- Does the boss say anything disparaging about the other team members during
the interview? Look out for indignant, judgy sorts of comments that indicate
that the boss feels shortchanged by the team he/she has (unless you are
explicitly being hired to single-handedly turn the team around).
\- Is the hiring manager, founder, etc., transparent about runway, the cap
table, and turnover rates? Playing it close to the vest about any of the three
is a very bad sign.
\- Do you see any VCs or investors stopping by uninvited and just hanging out?
If so that's a good sign and means there is transparency with investors (which
doesn't happen in all startups).
\- Are there "big company sounding" organizational titles like "Senior
Director", "Senior VP of x", "Senior Engineer", etc? If the company has fewer
than 200 employees, titles like these indicate a wide array of culture
problems, usually starting at the top.
~~~
HappyTypist
The last point can be unreliable, so use your own judgement. At my current
company people make up their own titles, so we have a "Vice President of
Engineering" and a "Chief Alcoholic".
~~~
grandalf
Those are fine, I'm referring to the minor gradations on each role, as in
Senior Manager Level 5, etc. Those are necessary in large, bureaucratic
organizations where working one's way up a predictable ladder is the goal. In
a startup, anyone who is more concerned with his/her title than with
experience and results is likely better suited for a large, bureaucratic
company where those HR-concocted titles are respected.

djloche
The best way is to interview your future boss in the interview process. Ask
about their management style. Ask about how many meetings they are in each
day, and the average meeting length. Ask about how they stay organized, ask
about what tools or systems they use. Ask about what recent technologies
they're excited about. Ask about the team and the individual team members.
When you are interviewing somewhere, treat it as if they are trying to
convince you and you need to ask a ton of questions to figure out if they are
a good fit or not.
Frame these questions in positive, generous light so you seem like you
genuinely want to work for them and are just trying to get all the details.
"What is the thing that most pleasantly surprised you when you started working
here?"

> _When you are interviewing somewhere, treat it as if they are trying to

As someone who interviews quite a lot of engineering candidates: we ARE trying
to convince you. That is no secret.
We want to know what kind of an engineer you are. If you're good enough, or
show aptitude to make up the lack of any otherwise expected skills, we are
interested. Even if we decide to pass, you _still_ deserve the same attention
as any other candidate. Treating a candidate poorly for any reason is bad PR,
and perhaps more importantly signals internal consent that it's okay to be
rude. That sets a bad example. (You do that once, don't get told off, and soon
enough others have picked up on it because who would want to spend any more
time on candidates we won't hire?)
When it comes to hiring, _everything is PR_.

noah__
I have about 12 years of exp. Have worked with all kinds of companies
startups\bluechips\valley\wall st etc.
Over time I have reduced paying attention to what they are dangling in front
of me, be it compensation or interesting stuff I want to work on.
I now mostly pay attention to the people. Specifically the quality AND loyalty
of people to the firm\manager\founder etc. The AND is critical. If its just
one or the other I walk. So for example, if its a 3 year old team and there is
no one "smart" who has lasted atleast 2 years its a good sign to walk. If its
a 6 year old firm and there is no one who has lasted atleast 2 years it's a
great sign to walk. If there are people who have lasted and aren't "quality"
its also not worth it. My definition of quality is they are smarter than me,
or have done something I have respect for.
If its a new company I don't work with them unless I personally know the
people involved.
Why these rules?
Cause if the people are "right" the interesting work and adequate compensation
follows. Doesn't matter if the project fails your time with such folk is never
wasted.

crispyambulance
No, No, No, NO, No (to all the tips and shortcuts)
Your first job out of college has a high probability of being a bad fit and
this is especially true if you're desperate to just get hired. So, it didn't
work out... happens a lot. The important thing to do is to figure out what YOU
want out of a job/workplace and to assess what that potential job can do for
your career.
I think its a waste of time to try to figure out some minimal set of "red
flags" to use for future interviews. Just look at the big picture, there's no
single red-flag that will tell you definitively that a place is miserable (nor
is there a single observation that signals an awesome place-- foozball and
snacks won't make up for asshole-driven management).
Perhaps even more important than what you observe during an interview is to
really examine your own needs and expectations. SOoooo many people are unhappy
WHEREVER they go and always blame it on management, co-workers, the industry
or whatever. This kind of serial discontent is a sign that the there's
something wrong with the individual rather than their workplace(s).
~~~
judahmeek
Do you have statistical evidence to support your claim regarding serial
discontentment?
~~~
crispyambulance
No. I don't know why anyone would even attempt such an experiment. These are
very subjective topics and it would be hard to even pose a testable
hypothesis. My claim is based strictly on life experience.
All I am saying is that people who take on one job after another and remain
unhappy would benefit from some serious introspection.
In other words, as important as it is to evaluate potential employers, it is
just as important to carefully examine one's expectations and career intent.
~~~

Your words: _" I think its a waste of time to try to figure out some minimal

tomtomAmazon
Lots of good advice here. I'd like to add a key phrase thrown around a lot,
'A-players'. As in, "we only hire A-Players for our team." Or "Our team is
made of only A-Players. If we hire anything less then the world ends." Beware
when managers/cofounders/leads/directors say this. Your bullshit detector
should be going off at this point in the process because what they're really
saying is that they only hire people like them, egotistical, shallow, puts
others down, don't ask for help since you're suppose to know everything,
expect them to talk about themselves ALL the time, expect a lot of bullshit (i
noticed that a lot of 'A-players' resemble the 'bro' attitude). It is
difficult on the first 'pass' to avoid such a situation especially without
experience. A company I worked for explicitly targeted young developers
because of the long hours, cheap labor (coder monkey?), the koolaid is easier
to drink without experience. good luck out there.

fapjacks
I always ask my go-to "red flag" question to all my interviewers. Remember
that _you_ are the one that determines what red flags even mean. This works on
everyone but the CEO:
"If you could change one thing without veto, what would it be?"
If the person describes a technical problem, that's usually a good sign. Long
silence is usually good (but can also be a very bad sign if they just can't
pick one thing). Trivial nitpicks are a good sign. _Any_ complaints about
communication are a very big red flag. Also any complaints about leadership.
Obviously, if the problem your interviewer describes is repeated by any other
interviewers, that is a big, red flag.
Piece of advice when firing this atomic weapon at your interviewer: Do not
fill the silence while they think with any talk. Let them think. Let the
silence hang. That makes people more likely to dig deep for something they
really don't like.
~~~
JoshTriplett
If you were the interviewer, how would you answer that question yourself?
~~~
fapjacks
I think I know where you're going, but the point of this question is that it
is unexpected, which demands honesty from people in most cases. You can't
trust a recruiter's answer, but if you're a programmer being interviewed by
programmers, you can usually trust the answers.
~~~
JoshTriplett
> I think I know where you're going
No, I was genuinely interested in the answer. I wanted to see examples of how
someone might answer the question.
> You can't trust a recruiter's answer, but if you're a programmer being
> interviewed by programmers, you can usually trust the answers.
I'd also be interested in the answer to that question from a first-line or
second-line manager. Whether they answered it honestly or not, the answer
would likely be helpful as part of the interview.
~~~
fapjacks
Oh! If someone asked me that question, I would describe the one change I would
like to implement the most! You're exactly right, there are a few things you
can measure with this question.
------
fma
I've read through most of the answers...and this is one of the few times I'll
say it but most of the responses are flat out wrong. Employees at a toxic
company will bullsh-t the answer. I know because I've been the one to
bullsh-t. The company sucked so bad, the turnover rate was high and the ones
left said anything to hire good employees to try to turn projects around. It
wasn't that the coworkers were bad, or the managers were bad. But it was
executives with unreasonable timelines.
So how do you prevent this from happening? I personally avoid a company where
I don't know someone in it, or know someone that knows someone.
Additionally, there's a nice hidden feature of LinkedIn. You can search for
people who used to work there. At one company I interviewed at, I searched and
found that those who used to work there...the majority left within a year. It
tells you something. I had a sense during the interview that the turnover was
high, and again they would BS me about their wonderful culture. Then I spoke
to someone who used to work there and he confirmed my thoughts. Oh yeah, the
fact they were going to throw a lot of money at me raised a red flag too (the
toxic company I was at threw a lot of money at people too).
Good luck.

Questions:
\- What do you hate about your job?
\- How unlimited is unlimited vacation?
\- What's the mean/median number of vacation days taken last year?
\- How have you shown that you value your employees?
\- How do you handle disagreements with potential hires?
\- If the team is split on a technical issue, how would this be resolved?
Company bullshit (bad signs):
\- "We want people who _want_ to work here. If salary is important we aren't
for you."
Uncomfortable answers to any of the questions, run!

techman9
The first one is especially important, I find. When I ask the question, "What
do you dislike most about your job?" or "If there was one thing you could
change about the work environment?", I expect an interviewer to have an
immediate answer prepared. If they don't, I assume that they either lack
critical thinking skills and are unable to independently drive change or are
expected to just follow orders. I don't have any desire to work at a company
where management does not respect input from employees and employees are not
encouraged to think about how things could be improved.
~~~
biot
Or management is very receptive and they have opportunities to point out what
does and doesn't work, and the things that don't work get addressed. Once
something is addressed, you tend to clear it from your mind unless the place
is filled with employees who really like to hold grudges, in which case being
able to instantly recall all the little wrong things might be a sign you could
end up with terrible coworkers.
Or having a canned answer means they've encountered this before and have an
acceptable response ready to go in order to cover up greater faults. If you
ask them and they immediately blurt out "Sometimes we work too hard" how
honest are they being? It's no different from interviewing a prospective
employee and they say "Sometimes I work too hard". Thus, an immediately
prepared answer is a very unreliable indicator. Just maybe they have that
answer prepared as experience has taught them to avoid being forthright about
the actual problems going on, because then they'd never hire anybody.
(Just playing devil's advocate. I really do think it could go either way,
dependent on their personality, how their mind works, how management operates,
etc.)
------
codingdave
Ask them directly -- don't phrase it "Hey, are you an asshole?", but ask them
questions that will help inform you of their approach to the organization:
1) What is your leadership style?
2) How do you resolve conflicts on the team?
3) Tell me about the communication style of the team.
If you get a chance to talk to team members without the boss being present,
ask similar questions - conflict resolution, communication, collaboration
styles, etc. This should give you enough information to judge for yourself if
it is a healthy team environment, or not.
------
BurningFrog
When I'm interviewing people, I won't come out and say what's bad about the
place, but when asked I will be honest with a future peer.
I think a lot of programmers are the same, so I'd ask the non managers
interviewing me what's the place is like to work at.
But... it's easy to "fight the last war" about things like this. So if for
your next job, you're 100% focused on finding a boss that's a decent human,
you'll probably succeed. But something other major will be wrong.

I previously left a company that I thought was great until I realized they
just wanted cheap work and a moldable individual for both emotion and
creativity.
I too just got out of college and tried to find my first job out of school and
took the first offer. These are the signs that I picked up on.
\- Arrived to interview to find that what I applied for was not what I was
interviewing for ... RUN! \- When trying to get a straight answer about
benefits or how long individual training may be and getting a lot of "I'll get
back to you" and no one does... RUN
\- When waiting for your interviewers and recruitment has to come in and ask
you if you have already spoken to your interviewers (i.e. their late or no
show) ... RUN either they are way to up their own ass or just terrible at time
management which if it's your future boss means they will have no time for you
\- Last one promise, when interviewing and you get asked questions that you
know the answer you gave to be 100% and they say it's wrong and tell you an
answer that isn't correct. Run!
That interviewer or interviewers indirectly just told you that they dont
follow or are going against what the documentation stateted.(in my case how
elasticsearch is configured)
I.e. you will work in an environment that will leave you with knowledge that
is incorrect and useless to use in another interview.

HelloNurse
Apart from egregious assholes and dysfunctional relationships (like the
mentioned husband and wife teams), there are milder and more "diffuse" kinds
of toxic environment.
For example: within the company, IT is a second class citizen compared to
production, so as a new developer you would start at the bottom of the bottom
with no valid career perspectives. Low budget, bad offices, low pay,
appearance of overwork are clear signs.
For example: aberrant company culture. Excessive secrecy and/or security
measures (who do they think they are?), extravagant recreational resources
(are they actually working?), excessive luxury (not bad by itself, but you
want them to spend that money on your salary), excessive conviviality, etc.
There is a meta-warning sign about company culture: refusal to show working
conditions and procedures to you because of conscious "discretion" and
subconscious shame. Also, you could like, accept as normal, or justify because
they make sense in context some of the bad attitudes you are aware of, failing
to see they are a problem.
------
MalcolmDiggs
When I walk into a company (for an interview), I try to get a good look at the
faces of the developers there, and gauge whether or not they seem happy. I
figure "In 6 months, my disposition is likely to be the average of the ones in
this room right now". So if the average person is happy, I'll probably be
happy too. If everyone is sleep-deprived, pissed off, and miserable, I'm
probably gonna be that way too.
I always try to go out of my way to meet the team and shake their hands (even
if the interviewer didn't plan for me to meet anyone). You can gauge a lot
from just a brief interaction with people.
------
woodcut
You're looking for personality flaws more than anything, it's hard it detect
them if they're charismatic enough to paper over their lies.
First off, protect yourself, ask to see the contract, guarantee any agreements
for future pay/bonuses are in there, the contract must specify working hours,
time off and notice period etc. Ask to see the resume's of the team you would
be working with.
Orange flags come to equipment, books, resources. A good company will give you
whatever you need.
Red flags are arrogance, delusion, recklessness, bullying.
Ask tough technical questions, see if they admit they don't know it or rubbish
the question.
Ask about ventures, projects things that went wrong, do they blame everyone
but themselves? How many people have left in the last 12 months? Ask to speak
to them.
How much runway do they have left? less than 3 months is a massive no. Has
anyone ever been paid late?
Honestly, if they're smart enough you can't tell until you're knee deep.

mrud
I think all your requests are good and can help identifying issues except the

unit91
I've had pretty decent success just being straight with people about my goals
and seeing what they say.
If I'm talking to other programmers and not management, I generally ask:
\- Are you happy here? Why?
\- Every job has little annoyances (important preface). What are some of the
things you wish you could change?
\- Do you believe your leadership is interested in your feedback?
I also REALLY try to observe the body language of the employees interacting
with each other. Even if I can't hear what's being said outside the interview
room, it can tell you a lot about the company culture.

trcollinson
So, what makes your boss such an "asshole" as you put it? I am not by any
means trying to prove whether or not your boss is actually an asshole, but
trying to find out why you think your boss is.
I have had bosses who I thought were horrible and many others around me liked
them. I have had bosses that I would go to the ends of the earth with and my
co-workers thought I was crazy. A lot of times it is personality and
confidence (in yourself and in your manager) which dictate how well you will
get along.
How to find the right match when you are interviewing? Well, how many dates
does it take for you to decide who you'd like to marry? Do you marry everyone
you date? In this business, I think it's best to not get too emotionally tied
down. You're going to move, and that's ok.
~~~
isuckatcoding
Ok so I can guarantee you this isn't all in my mind or some relativist
bullshit. This boss is the kind of person who walks into a meeting late, often
clueless about the topic of discussion, then yelling ensues because he's
confused or some feature wasn't implemented as he supposedly requested and
then he berates my team members in front of others and you can sense the vibe
of dog shittiness in the room by the utter silence that follows.
He is notorious at the company for being _the_ asshole boss. Just mention his
name once to employees (especially those who've been with the company for 2-3
years for instance) in other departments and while some won't say it out loud,
you can tell from their face they know and they feel for you.
I apologize for the swearing. In reality, I am actually the kind of person who
avoids swearing at all but this job is changing me in such terrible ways. Yes
I am angry and I am desperately searching for a decent company to give me an
opportunity where I can grow and contribute in a more positive environment. I
am not asking for a stress-free environment (stress doesn't signal the job is
bad necessarily) , I am asking for basic human courtesy and professionalism.
~~~
spinlock
Wow. Is there anyone ay the company you can talk to about changing teams?
Someone who's your boss's peer that you like and trust? Tell them it isn't
working out and ask if you can use them as a reference. You might be able to
change teams in the company but, if you can't, its always good to have a
reference.
~~~
isuckatcoding
This is going to sound like paranoia (and some part of it probably is). I've
thought about talking to perhaps HR or recruiting to see if I can move to
another department. However, I feel as long as this individual is at the
company, it will be difficult. This person is unpredictable. One day he is
happy. Another day, he is totally on edge and ready to shout. He might decide
that my lack of "loyalty" to him as a personal offence. He is close with upper
management (CEO, etc.) and he can easily influence them and potentially make
my life miserable.
You know its so funny. I love the company itself and the product. They truly
have some innovative technology (as cliche as that sounds).Though, I think the
lesson I've learned from all this is that I need to look at my manager(s) as
MUCH as (or more than) I look at the product or my salary.
~~~
spinlock
That sucks. Oh well, looks like you'll need to go outside of the company. Just
remember: don't badmouth your current company when you apply for jobs; just
say that your ready for a new challenge. No matter how unbearable your
position is, it never comes off well to gripe about it to the next person that
you're asking for a job.

For me, the _big one_ is whether or not the employer offers to give you a tour

is any refusal whatsoever, run away and don't look back.

YeGoblynQueenne
>> I am a pretty average developer
I don't have much advice to offer with your main question, after all I'm only
a few years out of uni so I'm barely a step or two ahead of you on the same
road. But I have this to say: you're not "pretty average"; you're just
starting out. You'll get a lot better and then things will get a lot better
for you.
I also valued myself pretty low when I started out so I ended up with jerks
for bosses a couple of times, but eventually I built up the skills to have a
bit more choice on the teams I was working for. At that point I found a team
with a senior engineer who became a true mentor to me and taught me a metric
ton of shit I'll be using to the end of my working days.
I think folks in this industry make the mistake of valuing innate talent above
hard work. It's true there's people who have that sort of magical talent and
godspeed to them. The vast majority of us though have to slog it out, and
learn as much as we can on the job and as we go. What "pretty average
engineer" really means is "bursting at the seams with potential to be a great
engineer with strong skills" a few years down the line.
Also: good luck out there. It gets better :)

When I interviewed for my current job, the whole (4 person) team did the
interview at once. Several times they talked smack to each other in the
interview - not mean, just having fun. Well, I can enjoy that, so I talked a
bit of smack to them during the interview. They hired my anyway.
When it's not done in malice, that can be an interesting indicator. It means
that the people on the team trust each other - trust that they can say such
things and have it received in the right spirit, and trust that the one saying
it isn't saying it in malice.
I wouldn't make this the only indicator, but it's an interesting data point...

hendler
Maybe interviewing elsewhere is only half of the solution.
We all end up in situations we don't expect. While bad leadership is hard to
overcome, it's a great learning opportunity. Now that you are there focus on
improving yourself.
\- improve your coding, on your own time or not
\- help your boss not be an asshole. or go above them. or manage them. That's
a skill too.
\- enjoy your paycheck, but save money
Hope that adds a slightly different perspective.

Just got hired myself. And I consider myself quite average too so here's my
experience.
My first job fresh out of uni was in a corporate environment and while I
appreciated the professionalism that came with it ("Keep an activity tracker"
etc ... might horrify some people but I love making lists haha) but in the end
I only stayed for 6 months. It got too corporate and suddenly I realised that
a lot of people were actually feigning cheeriness when underneath they were
under mighty pressure from politics. I decided quite firmly never to work for
corps (that activity tracker should have warned me after all) and for a few
months I freelanced until I got broke. I thought I'd give big organisations
another chance and I'm glad I did. When I had the interview, it was typically
based on a set of questions but the interviewers were relaxed and made warm-
but-not-wacky jokes. I also remember the time when I had a sudden mind blank
during a presentation and they were really amiable with it and said that it's
probably better if I spend a day with the team and see if we're a match. That
was probably the moment when I knew that this workplace could be a nice place
to work in, because they seemed to recognise and appreciate humanness and that
the interview is not just about testing _me_ but also vice versa. So if it's
possible, asking to meet your future team and seeing what the reaction to that
is like could be a nice indicator of the type of culture there. And of course
the actual team meeting.
I don't think there's a proper list of how to detect toxicity, so I guess you
just need to keep an open eye and ear on everything which is why it's
important to spend some time in the workplace. Keep alert but at the same time
keep an open mind. Interestingly, a week after I joined my new workplace, the
organisation did some ruthless restructuring, but which top management was
very organised and empathical about it, for example there was an emphasis that
we could talk about it, and comfort those who are leaving etc. It was
unpleasant and initially I panicked thinking that I picked the wrong workplace
again, but in the end it was educational - a couple of weeks later, the
emotional negativity dissipated. I'm still new but 1.5 months later and I'm
still chirpy ... well I'll take that as a good sign.

For me, over the years I spent a lot of time looking for the right atmosphere,
changing jobs once every one or two years. Then I noticed / worked towards a
change within myself and I think I am now better at recognizing a good match.
Unexpectedly, I am now also more open to more relationships in which I
wouldn't have engaged previously.
I know the ways in which I work best and I'm not afraid to let people know.
That confidence makes a big difference not only in who I choose to work with,
but also in how I work with others.
When gauging a new employer or coworker I decide mostly on feel. It's easy to
_recognize_ a matching relationship once you know yourself. That doesn't mean
it's easy to _find_ one.
It might not be true for everyone. In my experience, knowing myself helped a
ton, and I was the only one who could figure that out. I was always told this
growing up and had no idea what it meant. People telling me to "be yourself"
made little sense to me until I learned more about myself.

How do I learn about myself? (Serious question)
~~~
studentrob
Maybe try changing some things up and see if you're more happy or less happy
afterwards...
If I had a solid answer that worked for anyone I'd be rich! Many self-help
books try. 7 Habits (Covey) and How to Win Friends & Influence People
(Carnegie) are two I liked.
Ultimately the question is individual, so the answer is too. I'll just say,
when you know, you know. If you don't know, keep looking. So long as you're on
this earth you have a chance to answer that question and many interesting
others. When you do, you'll look back and be glad you tried.
I'd also say that it's a lifelong process and it seems equally possible to
lose yourself. For me I was not always aware of when I started slipping.
I started doing meditation recently and found it helps settle my thoughts and
become aware of when my brain was thinking things I didn't want it to. The
book Mindfulness in Plain English [1] was recommended to me, and I'm about
halfway through it. I'd recommend it to anyone interested in becoming more
aware of themselves and others.

Now that your know yourself better, are you more aware you slipping and take
preventive measures early on?

Q1: Covey would say there are some basic human needs. Physical health, money,
opportunity to be creative, challenge, social interaction. For me, absence of
creativity/challenge and onset of boredom has been a common theme. In the
future I'd guess I will be okay on that front and struggle with others.
Q2: Definitely. Some awareness comes from taking time to meditate, and some
comes from experience. I'm not going to argue I can anticipate everything or
that I've met all of life's challenges. That would be silly. But I do feel
more comfortable dealing with things day-to-day and feel less of a need to
plan/control the future.

Trust your gut.
No seriously, if you have a bad/weird/odd/sketchy feeling when interviewing,
that's all you need. Your subconscious picks up on WAY more than your
conscious does and it notifies you through that "gut feeling".
So don't listen to what others in this thread are saying. Their advice comes
from their experiences, which may not match yours. Only you truly know what
you want.
~~~
seeing
It's bad advice to say "don't listen to what others in this thread are
saying". Having more data is better than having less data.
It's good advice to trust your gut; but as Nobel prize winning psychologists
discovered, trust your gut as an additional parameter to your existing rubric
of tests.
Don't trust your gut while excluding everything else.

There are red flags to bad environments out in an interview, if the place is
really horrible. But looking very hard for problems in an employer during an
interview is a bit like looking very hard for problems in a candidate during
an interview: The more you have been around the block, the easier it is to let
those signals that aren't necessarily very strong to just take over, and that
leads to failure. The interviewer with the least red flags is probably the one
that is best at lying to you, or to himself.
So what I do, outside of tiny startups (where I'd not go regardless, as you
are in for years, and chances are you'll just be underpaid for the duration)
is to go look for former employees, and ask them why they left the place, what
sucks, what doesn't, and how generalized the problems are. People that have
left might overestimate how bad the place is, but better an overestimation
that you can temper than talking to someone that is still in love with the
place, right?
This mechanism has been pretty good for me, and you can show you are a well
prepared candidate by asking pointed questions about what the people that left
considered the place's most glaring weaknesses.
I have been fortunate enough to be able to do this a few times in my career:
In some cases, talking to my would be predecessor. It's helped me dodge big
bullets, either by avoiding employers altogether, or by letting me ask for a
different department/team in advance, avoiding terrible managers.

During an interview it's pretty hard to gauge whether the environment is a fit
for you. You're focused on performing well and you often brush aside things
that would irritate you otherwise. This is why I recommend "courting" the
company.
I've had ~10 jobs and 4 of them had intolerable environments. In the past few
years I started vetting the companies I wanted to work at by getting in touch
with current and past employees. This can give you some insight on how the
place functions. I also request to visit the headquarters/office. Most
companies will accommodate this. If they don't, I end the recruitment process
because it's a big red flag for me.
bpchaps's bullet list is pretty good too. I've run into each of the line items
in interviews. Particularly bad for me was Twilio, where the pre-screen phone
interview consisted of two developers asking me trivia questions about various
technologies. After the first 10 minutes I wanted to hang up. I was glad to
not get an onsite. Right before Digg went under I interviewed there. There was
no receptionist when I showed up, so the first interviewer (lead dev) didn't
even know I was there. We started the interview 15 minutes late, and the
interviewer took phone calls during the interview. I was extremely irritated,
but I kept my cool.
Just remember, if you are treated in a way you don't like during the
recruitment process, then you'll probably be treated in a similar manner if
you become an employee.

Here's my checklist:
\- If I'm asked a question, or asked to offer an opinion, do they seem really
interested in my response? Do they challenge politely/with an intent to gain
more info, or do they dismiss it?
\- Whats' the average tenure on the team? How long have people been there?
\- When asked the negatives or the challenges with the job, do they offer
substantive responses, or platitudes?
\- Are they interested in me as a person? Or is it just my skills and
background?
\- For the rest of the team, are they engaged? Do they seem to care about what
they're doing? Do their concerns/negatives about the job match what their boss
said?
\- What's the ratio of leadership to worker bees? Are there lots of VPs for no
apparent reason? Red flag.
It's largely qualitative, but I like to see consistency in temperament,
enthusiasm, understanding of the challenges.
Example: I interviewed at a company a number of years ago for an executive
leadership position. I met with four different execs, each of whom had a
different cagey answer as to why business wasn't doing as well as it could. I
opted not to join, as it "felt weird". Later I ran into someone I knew who
happened to have taken a job there who confirmed my suspicion that it was a
disorganized organization with a toxic atmosphere.
Trust your gut. If something feels wrong, it probably is, and don't let desire
to get the job override your instincts if you can avoid it.

I wrote up an article about probing for culture in the interview [0]. Here's
the tl;dr:
It's really hard to pull out the truth sometimes. Those that aren't looking
through rose-colored glasses are outright lying to you. No company sends
disgruntled employees to interview.
It's important to figure out if the company has a plan for you. If the plan
seems like "Change everything, but without any power to do it", book it outta
there. It's totally OK to ask folks what they think about management. Again,
rose glasses, but folks usually don't have a cached answer for this one so you
could catch them by surprise.
I find one of the biggest indicators of "Do I like this place" is how
disagreements are resolved. Ask about those. Press for details, don't take
sweeping statements for an answer. Actual examples are best.
Finally, lots of folks make bad decisions right out of college. I certainly
did. Very few folks will hold it against you if your first job is a short one
(~six months).
If you've got any further questions, contact info is in my profile. I can run
a mock interview if you're up for it. Hope I helped!

I have hired two to three dozen developers over the last 15 years for a fairly
boring developer job (finance) in a very big city (Atlanta). Here are a few
tips I had for making candidates feel comfortable.
1\. Find out as much about them as possible before they show up. Look them up
on Github, LinkedIn, etc.
2\. Target questions that are appropriate and related to the job. If the
candidate offers any sort personal info about interests follow-up with
questions and find out what they are really interested in, you should already
have a clue from point 1. If their primary love is talking about airplanes or
something else then writing code is not their first love.
3\. Make the candidate feel at ease as much as possible. Offer Water, coffee,
comfortable chair, etc.
4\. Have someone on their level take them to lunch. They can find out what
their potential future co-workers think of you and you can get some valuable
feed back from your devs.
If the person interviewing you doesn't do most of these things then you
probably want to run the other way. Remember your managers job is partially to
help you be successful and if he can't help you have a successful interview
then he most likely can't help you have a successful career. When you leave
the interview you should feel that this person has your back and will help you
out if you ever need it.

Everyone has different hangups in regards to how a company will treat them. My
personal tracer shots are always in regards to whether I can use the equipment
and tools and processes I want. Obviously the interviewer can give away that
the place might be bad to work with their questioning but I ask the questions
that matter to me to make sure they care about my productivity and autonomy
and if they don't I reject the job there and then.

I have never worked in an environment which might be called toxic or anything
that comes close. we don't do that this side of the ocean. however there are
still things to keep in mind.
-if they do scrum use jira have an open plan office or talk about estimates then those are big contra-indicators. if you get freedom about work times that's good.
-scrum is there to have better control over you aka big brother is watching you. same for an open plan office (especially if the entire team sits together). this makes for an environment where you feel watched all the time.
\- if they want you to come in at a specific time that's also because they
want to watch your entire work-day.
\- if they talk about estimates this often means a focus on efficiency and a
lot of pressure.
\- if they use jira then you won't have a say about what you will do and are
probably just a code monkey.
\- on the other hand, if they give everyone their own office, let people work
from home or give you more freedom about which time you come in then this
means they trust their employees and are a good choice.
\- if they ask you your opinion about things that matter then this is good too
(it means they are not just hiring you as a code monkey).

It's very hard to use black and white heuristics, because life is frequently
shades of gray. And there's a big difference between work as presented in
recruiting presentations, and what's it's really like. That's called Life, and
it's why we get paid.
2 things I've found that work:
1 - If it's a backfill for an existing role, find out if the person is still
is with the company.
1a - If the person who had it is still in the company, it's generally a good
sign, but ask to talk to them anyway. You may not get full information, but
you'll get some. (If they're just doing something else for the same boss, also
a good sign.)
1b - If the person who previously had the job left the company, reach out to
them and ask about the role. They'll usually be more honest.
2 - Find a friend, or a friend-of-a-friend who works there, and ask them. This
will get easier the more you work, as your network will expand. It's also a
good reason to keep in contact with everyone you meet. (LinkedIn helps a lot
on this, despite all the bad press that it receives)

I would add to other comments to watch out for people that believe their own
bullshit.
My current company I could tell that when the team lead talked about it being
Agile and using latest tech that he really believed it.
Because he believed it I joined, but now I realise he was willfully deluded.
So don't forget to watch out for this and verify what their practices are with
questions.

This is common in your first job, so don't feel bad for missing the signs!
Until you have been in the professional world it's hard to know what
environments are right for you.
The good news is that now you'll know what to look for when you interview at
new companies. Some things I look for: 1\. A well organized and well run
recruiting process. If they can't communicate, schedule and work with you
during recruiting it's unlikely they can do so when you work there. 2\. Great
employee retention. People don't stick around for a long while at companies
they hate. Look for places where people stay for the long haul (at least 3
years). 3\. Personal connections. Talk to the people you know in the industry
and learn about where they work. At this point I would have a hard time
joining a company where I didn't know anyone since there is so much risk
involved.
Good luck with your next adventure! It only gets better.

On the employers' side, a few studies showed very low correlation between
interviewer scores of candidates and employee performance ratings after
60-90-360 days. I suspect it's nearly as true in the other direction: that
interviews are little better than a coin toss in helping you know if this is a
great fit.
So this suggests a strategy to screen out obvious mismatches, sign on, then
abandon or confirm when you have enough information after a month or so. This
is one of the advantages of freelancing or starting under contract: both
parties have a chance to see how the other performs in the real world instead
of the artificial job interview setting.
So extract what clues you can from the hiring process but don't attach too
much confidence in their relevance to your ability to enjoy your work, to
perform well, or to advance your career.

One thing you can do is ask to see the space where developers are working. Do
developers there look generally happy? This is highly subjective and prone to
false-positives, but in general if everybody kind of looks like they'd rather
be somewhere else, take note of that.
Is there another developer in the interview besides the hiring manager? Do
they seem engaged and are trying to sell the job to you (a good sign), or are
they kind of disinterested (a bad sign)?
Are the interview questions adversarial? ("Solve this problem. Ha ha, that's
not right" \- bad) Or are they asking about you and your experiences and
trying to relate them to what you'll be working on. (good)
What specific aspects of your current workplace do you view as toxic?

Ask about the other employees. Executives, middle-managers, future co-workers.
What is their background? How long have they been working in their group? Do
they have significant prior experience working in a position such as this?
What is their day to day like?
Ask to talk to people in the group you're going to be working in. What do they
think of the company, their boss, team lead, other team members? Are they
often asked to do more than should be expected of them? Do they love their
position?
If they don't offer or won't let you meet with the future team, this indicates
they really don't care whether the team likes each other personally, OR that
they're so busy they have no time to meet you - which is not good either. It
should also be face to face; nobody gets to know someone over the phone.
Finally, you can use probing questions to see how your future boss reacts.
Make a joke and watch their body language. Ask them both professional and
personal questions. Ask them how they would handle different work scenarios -
would they throw a direct report under the bus, or try to cover for them? Do
they micro-manage or are they hands-off? How responsive are they to
communication, and in what forms? Do they work with many teams or just the
one? Are they customer-focused or task-focused? Is their primary motivation to
get ahead in the company, or merely to be helpful?
Sometimes there's no way to know if a boss is going to be a jerk. But 9 times
out of 10, either someone else working there has noticed it, or they'll act
like a jerk to you with the right prompting.

As a recruiter, I can tell you about the work environment but often times it's
only an overall view. If you have the opportunity to speak to employees that
is usually the best way to get information about the environment.
If speaking to other employees is not an option you will really have to lean
on the questions you ask during the interview. I would encourage you to have
standard questions for the people interviewing you, that way you have a
consistent way to rank a company or team.
Hope that helps! Lisa

The best way to detect this is to see the working conditions for current
developers. Then notice the vibe around the room.
Smiling people are a good sign. People that come to greet you and talk to you
(even if you are not yet hired) are also a good sign.
Refusal of that tour is a bad sign. People that seem grumpy, tired, or angry
is a bad sign as well.
You could also find a developer in the company cafeteria (or something
similar) after the interview finishes and ask him/her about the company

Some of the main things I've noticed:
\- Lazily using "full-stack development" for every position as a means of
avoiding the hard work of actually managing people, providing meaningful job
descriptions, and respecting specialties. A company with a huge army of
undifferentiated full-stack positions is a major red flag.
\- Unwillingness to negotiate regarding private offices or remote / work from
home options for people who are not compatible with the noise & productivity
loss caused by open-plan offices.
\- Hyper focus on your salary expectations early in the process without
reciprocal willingness to share the budgeted salary range. This extends to
hyper focus on relocation costs or other compensation items too.
\- Jobs that don't provide relocation. Sometimes there are good reasons, but
many times it's because of cliquish culture and/or extreme cheapness.
\- Paternalism: does the management act like your vacation time, your pay,
other forms of compensation, or other perks are "generous gifts" doled out by
the company? Do they act like the company "is a family" and have weird
workplace cultural norms about key management "principles"?
\- Are all of the recent Glassdoor reviews 5-stars with unrealistically
glowing reviews that sound like they were written by a PR firm, and all of the
bad reviews are buried at the end and sound like what an actual human would
write?
\- Any unreasonable demands for access to private data about you, such as
statements about past income or addresses, test results for things like IQ or
personality tests. I agree with other comments that even asking for test
results is a bad sign, but even if the test results were legitimately useful
for hiring (they aren't), there's still the issue of distrusting some random
company with private data about you, or being skeptical of their network
security.
\- If anyone tries to talk you out of your financial requirements with lame
excuses, it's a red flag. For example, when I've countered lowball offers
before, I've had HR reps debate with me exactly which apartment buildings and
locations nearby I could live in at the wage they countered with. Anybody
prying into your private life like that ("hey I know where you should choose
to afford to live") is nuts, and you should run away.

The simple answer is realize your more nervous than the person or group
interviewing you. You may not be completely yourself as your nervous, but they
are being themselves.
If they act aggitated, aggressive, nervous, rushed, etc... Thats most likely
either their true personality or a real problem of their workplace.
When you ask to meet your coworkers are they nervous or friendly. Does their
boss say anything nice about them... Etc...
------
hacknat
Ask straightforward questions. The way people answer them is more important
than what the content (mostly) of those answers are:
Examples:
1\. Do you like working here? You should get an impression that the person
genuinely likes working there. If you have to drag enthusiasm out of them
that's not a good sign.
2\. What's your management philosophy? They should have one, or at least be
able to sound like they've given it some thought.
3\. Tell me about a time you disagreed with your manager or somebody senior,
what did you do, what did they do? What ended up happening? What your looking
for is a manager who is willing to admit some degree of political prowess. You
DO NOT want to report to someone who cannot stand up to their seniors, it can
be just as bad or worse than the overly political managers (the overly
political managers at least get somewhere sometimes, you and your team will
get resources, project wins, etc).
More like this. Whatever question you'd like a direct answer on. Ask it, most
likely you'll never get the whole truth, but the way these questions get
answered matters.

Look around on the internet beforehand, since it's filled with sites where
employees can post experiences they've had at other companies. You mention
Glassdoor, but perhaps some of its alternatives might be useful as well:
Like Rate my Employer
([http://www.ratemyemployer.ca/Home](http://www.ratemyemployer.ca/Home)), Job
Advisor ([https://www.jobadvisor.com.au/](https://www.jobadvisor.com.au/)),
Kununu ([https://www.kununu.com/](https://www.kununu.com/)) and The Job Crowd
([http://www.thejobcrowd.com/](http://www.thejobcrowd.com/)). Yes, all these
sites can be gamed if the company is persistant enough and floods them with
fake or coerced reviews, but they can also give some impressions on what
working there might be like.
You should also check social media sites (LinkedIn and Twitter might be good
places to find people's opinions on this stuff), as well as general mentions
of the company's name in general. After all, if a bunch of articles start
talking about how terrible the environment is on Medium, then that's probably
a giant red flag right there.
If you can find out, knowing the general level of staff turnover might be a
useful metric too. Does the company often get people who work there for a
couple of months and then quickly move on? That's a pretty good sign it's not
a great place to work. If you see a bit of talk online about how a large
amount of the team quit at once, or that staff turnover is high in general, it
often means something has gone pretty wrong in recent weeks.
As for what to see in the interview... well, I guess pay attention to the
working environment, the behaviour of the staff, etc. If it looks chaotic or
the employees look utterly miserable, then those could be warning signs in of
themselves. Of course, you might not be able to tell this (if a company is
very careful about their interview process), but that's pretty rare for
startups and small businesses.
Hearing a lot about 'culture'or 'company fit' might be a warning too, given
how often it means 'acts like the boss/other staff and shares
views/background'. As might the usual complicated interview procedures,
suspiciously low pay, the office being in the middle of nowhere, etc. And

Just an additional note: If they start disparaging past employees,
competitors, etc., run. They will have the same attitudes about you.

From my experience, I was lucky to have good managers that seemed ok during
interview and even after I started working. What changed my situation for
worse was new manager, either replacing my direct manager or being put above
my direct manager due to merger,change-in-structure,etc.
Then my situation took a dive. New managers usually don't like non-super-star
employees already there when they are brought in from outside. They didn't
hire you themselves. And they are under pressure to do better. So if you are
an average worker, you have a big fat target on your back.
All points on this thread were great. But you never know about life, what will
happen tomorrow.
So don't feel too secure or cocky when things are going well. And don't feel
too down when everything seems to be going against you.

By the way Glassdoor is subject to subversion by a company's HR. Go to
Theranos' Glassdoor postings and ask yourself whether the glowing reports
sound like they were written by employees, and further, whether it is
reasonable that they coexist with some of the rotten ones.
------
laxatives
Ask for something a little outlandish and maybe unrealistic, like taking a
sabbatical/working remotely for a few months while you travel (this probably
only works at a startup without a formal hiring process). If they are willing
to at least entertain the idea, its a good sign.

Basically, you have to treat the interview as a two way process - they are
interviewing you, but you are also interviewing them. You need to look at how
the company has treated you from the moment you applied, and pick up on any
indicators that the organisation you're applying to is toxic.
I would look at the following:
(1) How has the company communicated with you since you applied to the
position? Has it been a single person communicating to you, or several, or an
automated process?
(2) How did you find it – personal or completely anonymous?
(3) Was there a telephone screening interview with HR?
(4) How were you tested technically? Were you sufficiently tested?
(5) Did you have to write code as part of your interview process? If not, this
is a major failing. If the company doesn’t know if you can code or not, what
is the point hiring you?
(6) How large was the interview panel? This is most visible way of assessing
how important a company views recruiting developers.
The interview itself:
(7) Were the questions asked relevant to the work you believe you will be
doing?
(8) Did the questions asked match the advertised job? If it doesn’t, it is
likely that the job advertised won’t be the job you will actually be doing.
(9) The interviewer’s personality and behaviour. Were you treated with
respect?
(10) Would you like to work with these people? Remember, in an interview,
people are on their best behaviour on both sides of the table. If you come out
of an interview thinking that one of the interviewers was a pain, then they
will be most likely be a complete bastard to work with. You need to trust your
gut instinct about people.
(11) How was the outcome communicated to you?

Simplest way I know is asking about the employee churn. "How many have quit in
last N years"? If it's uncomfortable to ask a manager or recruiter then find a
team member and ask.
This is culturally and geographically dependent though. In a tech hub kind if
area, holding a job less than a couple of years isn't strange, in my home town
where an average tech employee is 45 and not 25, I'd run if the average
employment was lower than 5 or 10 years. So it depends.
If a third of the team quits quit last year that's a pretty good sign that the
environment is toxic. And it becomes only more toxic since usually the talent
leaves first.
Oh: also if you have kids - the killer question is "does everyone in
management have kids"?

Some great answers and advice here. I'd add questions about behaviour when
things go wrong. For example, what happens when a deadline is missed? Who is
accountable (correct answer being "team", or "everyone")? How do lessons
learnt affect subsequent projects?
Took me a while to find a good formulation for these questions - during an
interview I now say something like "Facebook, Apple, Microsoft and the like
still miss deadlines, so it's a given that smaller outfits will, too. How do
you deal with missed deadlines, and how are teams affected by that?"
I look for more occurrences of "we" and "us", and fewer of "I", "he", "she"
and "you".

First, Now that you have an understanding of the type of boss you don't want,
I would suggest trying to understand the type of boss that fits you. A bad
boss to one might be motivating to another. Ask questions like: How do you
support your team to be successful? Tell me about a time when an employee
impressed you? I'm an average developer now but want to be great, can you help
me get there? How? How do you protect your team from outside distractions?
(most importantly) Why did you come to work here and what are you looking to
achieve?
Not that these questions will fully determine the quality of the boss, but you
can get a sense for the empathy previously mentioned by how they answer the
questions.

I'd probably recommend you use the same tricks a good interviewer does to
determine if you are a good culture fit.
1) know your requirements 2) use behavioral questions instead of hypothetical
3) trust your intuition 4) hold a high bar

I interviewed at one place where the manager who was supposed to see me turned
up an hour late, sweaty from a cycle ride and said I was too early. He
consistently got my name wrong during the remaining half hour, and poured
scorn on his current reports.
\- If during the interview, they ask you if you have 'firing skills' and how
you motivate unmotivated staff, that's a strong indicator also. The company
was based 20 seconds from the edge of a airport runway. Repeatedly during the
interview, we had to stop talking as the noise from jet engines wouldn't allow
normal conversation.

What do you mean by "asshole"?
During my first engineering job out of college, I had a crazy angry boss whom
you could hear yelling at people all the way across the building. I used to
dread having to meet with her (at least) once a week. I literally had to
remind myself that "no matter what, she cannot take my life". Yes, this was
ACTUALLY a recurring thought.
It didn't take long after I had already left that job, that I realized how
good she made me. Among my peers, I'm the top engineer, and she's the reason
for that.

Good luck!

I'd like to know the inverse. I accepted my current job because I really liked
and respected my boss (and still do) - enough that it obscured how
dysfunctional and mediocre the company was in general. I even turned down
another offer with more responsibility at another (name brand) place because
their hiring manager was such a dud by comparison.
I'm looking again to escape my current abyss but am just so paranoid that I'll
end up in another mess due to simply liking my boss & coworkers during
interviewing.

Always treat interviewing like dating, of-course sans the romance; especially
the one with your future manager/tech-lead.
How do you tell if the person you're "dating" is crappy/toxic? That judgment
is very subjective, by definition. e.g. I've had my fair share of people I've
found "crappy/toxic", that others have not. And vice-versa. You want to find
the person/manager that _you_ get along with.
The only way for you to truly tell, is to
1\. Spend more time with them _at the right time_ :
\- The best time to do so, is when the offer is made, but before you've
accepted it. That is your best time; most companies will do pretty much
everything they reasonably can, to keep you interested in that phase. Make use
of that time, to ask for more conversations with the potential manager/team.
I used to work in engineering at Box for several years. Box is very thoughtful
about their interview process. We used to invite candidates we liked, for
dinner with the team and multiple conversations with the manager. They were
also very selective about promoting people to management positions.
2\. Do backchannel references:
\- Hit up past employees on linked-in. Especially the ones who stayed at the
company for a long time. They'd likely know your potential manager and will be
able to correlate them with the culture.
Don't feel shy in doing so; it's routine. Of course, BNBR with their time.
Generally speaking, in interviews, you have to optimize for "fit" with "you".
Do the best you can in the time that you have, and then leave the rest to
chance. There are many good people and strong teams out there.
[I make these observations based on my past life as an early engineer at a
couple of companies, as engineer and Director of Engineering at Box and as
someone keenly interested in interviewing as a topic. These days, I pour
myself into running a bootcamp for technical interview preparation:
[http://Interviewkickstart.com](http://Interviewkickstart.com). We believe
that all good engineers deserve a chance to work for best companies of their
time, and interview preparation should not stand in their way]

As a recruiter, I would say the best way to judge a company is by what the
current employees say. It's not always possible to speak to employees and then
you have to lean on the responses to questions you ask during the interview.
Have a set of standard questions you ask so you have a consistent way of
ranking the responses.
Before you walk into an interview or even have a telephone interview decide
for yourself what kind of company, culture and environment you want to work in
for a lengthy period of time.

Adding to what most of people said: 1) look how hard the technical part of the
interview is, if you don’t get any challenging questions (technical and to
some extend behavioral); you are most likely not going to learn and grow that
much if you get the job.
2) how the interviewers treat you when you are trying hard to answer tough
questions? If you see sympathy, it is a good sign; if they play bad cop and
good cop, run.
3) if they don’t ask you any personal questions it means they will not care
about you.

I think this is the biggest factor when I take a job. Do I like the boss? I
say the beer test - would I enjoy hanging out with this boss socially. I'm not
saying I would, in fact I rarely have with my bosses, but someone who seems
like I could be friends with is someone I want to work for.
This has lead to me mostly working for bosses with good people skills which is
rare to find in tech. I hate working for socially obvlivious robot programmers
who can't solve people problems.

There's no foolproof way of detecting bad bosses and environments.
What you need to learn is:
(1) How to deal with difficult people. It's very likely that you'll have to
deal with personalities and egos like this at some point no matter how
carefully you attempt to situate yourself.
(2) How to make yourself marketable enough that you can easily walk from
uncomfortable workplace cultures. At some point you're going to work with a
colleague or in a company that you cannot stand, so be ready for this.

Well then, do better and don't look back.
There is no shame in taking a first job out of college and realizing it wasn't
meant to be.
Working at your age should be akin to dating...you should have no guilt or
issue with realizing you acted without having complete information and perhaps
jumped into something that wasn't, in the end, right for you.
Why not start actively shopping a resume and talking to colleagues your age to
see where you could possibly land next?
Good luck, and keep moving towards a better tomorrow.

What did your gut tell you? You said it was a great startup but what was vibe
from hiring manager? I'm willing to bet you didn't feel excellent about him or
her.
Its the best tool. I had a certain feeling about my curemt boss (like this,
don't like this) and its right on the money 4 months later. Just get a sense
from what they focus on (and what they gloss over), how they talk, their body
language, and more.
Next time ask how excited you are to join that person's team

Since this is your first job out of school, this tip won't help you
unfortunately. In any case, it's good to keep a buffer of 6-months spending
handy in savings (outside of retirement accounts, those should preferably
NEVER be touched outside of TRUE emergencies). Having a buffer-fund, you will
find, will keep your mind at ease and give you options to walk away from very
toxic environments. Good luck buddy!

Assuming you're doing a typical full day interview loop pay attention to the
first few interviewers, they're likely more of the junior employees. Ask them
lots of questions about the work environment, boss, etc. Obviously don't come

'what's the work/life balance like?'.

lnanek2
That happened to me recently. Everyone seemed great during the interview
process, but the company was a disaster.
Once I got in the door I found out all the code was originally produced from
outsourcing in Russia. So it had no comments and it had layer after layer
after layer of unneeded abstraction. So figuring out the behavior on an error
in the BLE back end communicating with a fitness tracker required tracing
through half a dozen unneeded classes like screen config beans, screen states,
the fragment state generators, to to error codes, to error messages, to
fragment subclasses, to flow subclasses, to activity subclasses. All with
if/else's for special conditions jammed everywhere even in things that should
be mindless DTOs and many parts never actually used and deep inheritance
hierarchies. It could all have been easily done with 40 classes instead of
120, with much simpler, more reliable code.
Lesson: ask the company about outsourcing history and plans.
Software engineering has known for a long time that abstraction over
composition really hurts maintainability and reliability, but clearly this
company never heard of that. Normally this sort of thing is fixable, but the
couple staff developers they had brought in tended to just write whatever they
thought would work, shove it into the app, then call it a day, not even smoke
testing, let alone writing unit tests. Developers frequently pushed code that
didn't even work in real testing on a device then left for vacation for a week
leaving others to deal with their mess. If you sent them an email with logs or
even fix commits, they'd call a meeting with management to try to discredit
you and block the fixes rather than working to fix the problems. And their
stuff simply didn't work on the devices, so there was no possible end goal to
their politics that would leave the app functional. It made no sense.
Even ignoring things that could be considered "style" they didn't have much
technical ability either. They thought changes to variables would be visible
on all threads as long as they used an Android Handler class on a background
Looper, but that's only true if both threads where it is read block on the
underlying event queue, which wasn't happening in their code. But they fought
the synchronization blocks that would make the value changes visible to their
UI logic despite logs proving their code was blowing by changed values without
seeing them.
Lesson: their developers will give you a technical interview, but be sure to
ask your own questions and determine their level as well.
OK, outsourcing, we can clean it up. Clueless junior developers, we can train
them and pair code with them and clean up up their messes. But management was
completely screwed up as well which kind of prevented any fixes. My manager
left at 4PM every day to go ride his bicycle and never came back. Meanwhile, I
took a 45 minute bicycle ride midday and worked until 8PM to finish a project
for the company during a month we were encouraged to exercise and be healthy -
he fought to get me in trouble for "long lunches".
Similarly, my wife drove two hours once to get me in without standing an hour
on the BART, so my back wouldn't hurt. She did everything properly, got a
guest badge, stayed out of restricted areas where we were working on
unreleased products, and got kicked out by the manager for talking quietly at
my desk with me and a coworker. He was panting heavily and claimed she was too
distracting for him to work. She left and never came back to the company ever
again, but he went right back to harassing me about her week after week,
talking about her and making up new rules despite the fact that she never came
back. Meanwhile he had reserved an entire conference room for his friend's
family to visit the entire day.
Lesson: not sure how to avoid this one.
The manager said all the right things during the interview, that management is
supposed to help employees get things done and get along with their team, but
he spent what little time he was on site harassing people. I guess because the
company had just IPO'ed the management was basically rich from their options
and didn't give a damn about actually working. I put in a transfer request
with HR who immediately fired me instead of looking into it. They claimed all
their managers were the same, which was a lie, since I walked around and
asked. So no clue of the right lesson for that one. Sometimes you just end up
with a bad company despite doing everything right.

Sometimes it's one small thing!
I had a senior member interviewing me not a manager ashe recently quit. at the
time I noticed he seemed annoyed and unimpressed. At the time I didn't think
much about it but after 3 months working there I realized I made a big
mistake.
There had been 5 others before me that lasted less than a year, some less than
6 months. This senior guy was a cranky, controlling, and micromanaged
everything I did. he was just a d$@k!
we finally got a manager at 6 months who seemed nice at first so I stayed in
hopes of change. after a month he started isolating individuals in the team.
he would start with one at a time and would start talking bad about them to
everyone in the dept. he would ignore them and isolate them from the team. he
then would start pulling work away and only give them boring tasks that was
well beyond their pay grade. one-by-one each individual would quit!
After 3 had left I was next in his hit-list. I took bullying and abuse for 6
months, I refused to let him win, and it was brutal. Isolating me from the
team by moving me to a corner section of the office. he would argue with me on
anything and would pull work away from me constantly. basically I was sitting
there with nothing to do, and if I did anything I would get in shit for not
asking for approval and if I did he would say no. unfortunately for him I was
well liked in the company and that seemed to Pisa him off more.
On my last 2 months I had enough and I would do whatever I wanted regardless
of what he said and he didn't know how to handle it! He would say "I told you
NO@ and I woild say "I'm tired of sitting there doing nothing all day so if
you have a problem with me working fire me!". it was so bad the HR manager
asked me why he has treating me like that for 6 months I told him he's a bully
and he's a terrible person. the HR guy agreed but said there was nothing he
could do but talk to a VP.. nothing happened.
One day, totally bored and miserable, I said to myself "why are you still
here?". I left, and I should of left at 3 months. they HR guy threw to a of
money at me to stay but I said there isn't enough money in the world to keep
me in this environment.
I keep I touch with a few individuals and he started bullying others and one-
by-one they left. actually one just asked me for a reference as he was
miserable and being isolated.
there are a lot of terrible people out there!

Strategy: Front S3 with a Caching Proxy - pbnaidu

jm4
I'm not sure this improves the situation much. In fact, it probably will only
make things worse since you've got an additional point of failure.
The proxy will keep your site up if S3 goes down, but if the proxy goes down
you're done. This strategy hinges on the assumption that your caching proxy is
going to be more fault tolerant than S3. The recent problems Amazon has been
having aside, that's not a gamble I'd be willing to make.
Nevermind the fact that even under the best circumstances this is only useful
for reads.

_Generally speaking, you want to fill up as much RAM as possible with
passenger processes without utilizing swap in order to maximize you
performance and throughput._
Uh, what?
On a single-app box with real traffic (as the article implies), look first to
CPU. If your average request spends 50% time in db/services and 50% time in
processing/render, using more than 2-3 passenger procs per core (i.e. 100%
core utilization) is less efficient and a waste of memory. Multiply by cores.
(Back off a bit for db on the same machine.)
You want plenty of spare memory for OS cache, to keep your code and static
files in memory -- that is, your disk reads should be zero.
And don't do swap, kids.
~~~
jnewland
Excellent point, Jeremy. This article didn't talk at all about the CPU/RAM
balance, which is a important to consider when scaling any application. In my
experience, a large number of Rails apps are more RAM bound than CPU bound due
to large gems/libraries/codebases.
Having additional Passenger processes available even when CPU bound will allow
for greater throughput (if at a less-than-ideal speed) than having requests
back up on the queue, however - especially if those requests spend a good
amount of time waiting on DB, memcached, or other external API calls.
~~~
jeremyw
If you're CPU-bound, you can't have greater throughput, by definition. Once
you calculate your non-cpu latency (50% in my example) ceil(1/latency%) is
your limit per core, before you start wasting resources.
~~~
jnewland
You can't gain any more cycles, of course, but you _can_ gain throughput by
adding processes to an already cpu-bound app by giving faster incoming
requests a place to go instead of sitting on the global queue while waiting
for other requests to process.

Made me think about backwards compatibility. Backwards compatibility often is
what allows a new platform to be successful (or to have a shot at success) and
yet it can hold it back from what it would have become without it.

Takipi – Java debugging reinvented - nivstein
http://www.takipi.com/
======
steve_barham
I want to test this product, and I'm in a position where I could spend real
money on a purchase or subscription to this service in the event that it does
what we need.
Unfortunately, as soon as I see that data is sent off-site, I immediately
discard this as a product which my organisation can use.
Reasons
1\. I am an engineer, working in a highly regulated environment. Regulated
environments excel at buying things, or subscribing to things - we have whole
teams of people that are delighted to spend money on our behalf. They also
tend to have immense amounts of process overhead, whenever you interact with
third parties on subjects relating to intellectual property or the
confidentiality of client data.
Your assurances on encryption, confidentiality, etc. are irrelevant to me; you
could have invented a perfect cryptosystem, but regulations would still
prohibit me from exporting data outside of our organisation.
2\. I don't want to build reliance on something which is outside of my
control. This might be the greatest tool ever built, but if I'm building
monitoring systems for production systems, I need to have confidence that they
are available, irrespective of your schedule for upgrading / supporting /
maintaining your product.
Why should a tool fail, just because the people that built the tool are no
longer around?
Short takeaway - my suggestion is that you consider those of us who are not
fortunate enough to work in unregulated industries, and produce a self-hosted
version of your application (as GitHub do) which can be run on our own
infrastructure. There's revenue there which is being ignored. You might feel
that centralising your service means that crackers can't steal your tool and
use it for free. I would argue that the people that actually care about
running this locally are the sort of people that will be paying you,
handsomely, for it.
~~~
nivstein
Hi Steve. These are some valid points you're making. We are currently
considering an on-premises solution for precisely this situation you are
describing.
------
DaveLond
This looks interesting, but the lack of any pricing information makes me
nervous - am I missing it?
~~~
nivstein
Takipi is in open beta, so it is currently free.
~~~
DaveLond
A not unattractive price point, I find. When are you planning to start
charging for it?
~~~
nivstein
Nothing is final, but we should remain in beta at least until the end of the
year.
~~~
hga
I'm afraid I have to agree with brazzy; you're asking people to invest a fair
amount of time, and potentially come to depend on a tool that they have no
idea if they will be able to afford once you start charging money.

farmdawgnation
This seems pretty legit. I really like the personality you gave the site with
its design.
Do you have any plans to support GitHub repositories as a location to pull
source from in the event we don't really want to deploy a jar with our source
in it?
~~~
nivstein
This is actually a feature which is currently under consideration.
------
namdnay
How well would this handle Spring code (in full autowired, horrible stack
trace glory)?
~~~
nivstein
When you install Takipi, you are asked to enter your top packages (e.g.
"com.mycompany;org.foobar.common"). Code outside of the filter will not be
shown to you when viewing stack traces. In addition, if, for an example, an
exception is thrown by Spring AND caught by Spring, you will not receive an
event for that case.
------
rsanders
Is anybody using this for Clojure? I'm very interested in how usable it is for
that.
Clojure runs on the JVM using JVM bytecodes, but that doesn't mean Takipi will
be able to show me anything but mangled gibberish.
~~~
nivstein
Takipi lets you attach your own source code to the project, so you will see
your original source code when viewing exceptions and other events, instead of
decompiled Java. Support for prettier stack traces is in the planning.
------
avisk
If I understand correctly does the takipi daemon, upload all the debug info.
collected from our server to the takipi server via Internet. Then I use
app.takipi.com to access the same?
~~~
nivstein
Takipi's agent records information which is relevant to the issues which are
detected (exceptions, latency problems, custom conditions set by the
developer). The data and source code are then encrypted with your secret
256-bit AES key and stored by Takipi. This data is in turn decrypted in your
browser and viewed by you at app.takipi.com.

I know it works on the JVM level, but we use Glassfish a lot in production and

buddym
What people sometimes fail to realize is that proper testing disciplines can
mitigate practically all bugs in production. I haven't seriously used a
debugger in 2 years, methinks. So giving developers "X-ray vision" to their
servers in production, however innovative, is not a real solution.
~~~
Uchikoma
As you are down voted I wonder: I have the same experience here. Very few
serious problems (1/year) that come from developer bugs. Others seem to have
much more, e.g. when people ask me if the devs here have pager duty (which
they haven't).
I also wonder if we test too much (ca. 85% path coverage, 15k unit tests (3x
rewritten), automatic selenium tests, explorative manual tests, automatic API
tests, developer acceptance tests).
~~~
lmm
It certainly sounds like you're testing too much.
The most efficient use of resources is almost always proportionate allocation
between code and other things. So if only a small proportion of your serious
problems are code errors then you're either testing too much or not doing
enough at other levels of the stack.
The real questions of course are whether your defect rate and the rate at
which you introduce new features are where you want them to be.

Ask HN: Do YC Startups Lack Spine? - villageidiot
By that I mean the kind of business instincts that are needed to really make a killing in the marketplace.<p>There seems to be an abundance of admirable nobility in the aims of YCers but not a lot of ruthlessness.<p>Maybe this is a function of the relative youth and inexperience of most of the groups that apply.<p>Would YC be more profitable if they were more open to older entrepreneurs that are ready to rumble?
======
pg
Textually this is a classic troll. But at least it's not an account newly
created for the purpose, so I'll give you the benefit of the doubt and play
along.
Let's start by clarifying your question. Did Larry & Sergey, when they
started, have these business instincts about making a killing in the
marketplace that you're referring to? Because if they did they seem to have
been well hidden. And if they didn't, these qualities don't seem to be worth
much.
Also, can you tell me more about the youth and inexperience of the people who
apply to YC? No one, as far as we know, sees the applications except us.
Your last question I can at least answer with certainty: no. It takes 4-5
years for a startup to achieve liquidity. No YC-funded startup is that old;
the median is only about 18 months old. Our profitability now is therefore
noise, which means no change in the applicants would have affected it
significantly.
~~~
villageidiot
I appreciate you treating the question in the good faith in which it was
intended. While the topic may be provocative, I felt it was relevant, based on
my observations of YC. However, because I can only provide anecdote as
evidence of my case, I asked the question to discover whether my observations
about YC are shared or whether I am suffering from a delusion. Textually this
may seem like trollish behavior but some of the responses to the question seem
to belie this suggestion.
As for your point about Google, some ideas are so powerful that they fall
outside the conventional expectations of business practice. The fact that
Google's founders have, until lately anyway, been unassertive in the manner of
Microsoft, does not indicate that Bill Gates' approach "is not worth much".
Absent some ground-shaking idea like Google's, I would argue the assertive
approach of Microsoft is the norm for a successful company and a key
ingredient missing in the YC environment.
~~~
mattmaroon
How "assertive" was Microsoft at first? It seems like they spent their first
decade toiling along at standardizing programming across the many different
OEMs and computer types of the day. It was probably another decade until they
did anything that anyone would consider "ruthless".
They started off trying to build something people want (Basic for the Altair)
just like any YC company. I wouldn't say that most YC startups display any
less ambition than building a Basic interpreter.
~~~
brandonkm
Mircosoft was VERY assertive at first. Without laying out a detailed history,
very early on gates had a keen business sense and was quite ruthless. They may
have been 'building something people want', but the seeds of what microsoft
would later become were without a doubt being planted.

mattmaroon

------
cabalamat
What is the optimum amount of ruthlessness for a startup to have?
I think this depends entirely on what industry sector a startup is targeting.
For example, a startup in the drug dealing, extortion, pimping or organised
crime sectors should probably be very ruthless and very "ready to rumble".
But for a website -- the sort of business most HN readers are more likely to
be in -- ruthlessness is much less likely to be effective. The thing you're
most likely to achieve with it is getting people to think you're an arsehole.

they've been too "ready to rumble".

Check back in a few years. We're only three years into observing the YC

login to e*trade and transfer it, or I'd write a check for it. Doesn't seem
worth giving up 6% for the cash, though if I were intent on striking out on my
own, I'd almost certainly talk to YC, to see if a "3% for $1 and

Sounds like the Bill Gates school of IT. The YC startup community has a
different set of social mores which emphasize usefulness of the product, a
certain trendiness with respect to what else is happening in the current web
2.0 world. We are not really the budding monopolist types. Yes, there is a
certain timidness in the YC community about the dark art of business. But
that's mainly because most of us have never worked :)

Well, I've worked in the business world. But I have no interest in
"assertively competitive business practices". Most of the managers I worked
for who were comfortable with that type of approach were exactly the reason I
wanted to escape into the startup world and never look back at corporate life
again. So, if you want to call that 'timid', go ahead. I'd rather do my own
thing, make a good product and try avoid "doing evil" as much as I can. This
probably sounds cliched or like I'm trying to win some brownie points but it's
actually how I think. It's not worth it for me to live in that kind of
"assertively competitive" way that I see my father and his colleagues living -
or working, I should say. That feels like the old way of doing things.

Responsible Disclosure Can Be Anything But - daeken
http://daeken.com/responsible-disclosure-can-be-anything-but
======
sriramk
I'm shocked he didn't even try to contact Onity. He's trying ascribe
motivations and possible behavior just based on his reading of the lock market
- we have no idea whether Onity would have acted in this way. Perhaps they'd
have scrambled to contact hotels? Or maybe they'd have disregarded it.
We have no way of knowing because he never attempted to do the right thing.
~~~
luu
Don't we have a good idea how they would have responded from how they've
actually responded? It took four months and a huge public backlash before they
acquiesced to demands for replacements.[1]
[1] [http://www.forbes.com/sites/andygreenberg/2012/12/06/lock-
fi...](http://www.forbes.com/sites/andygreenberg/2012/12/06/lock-firm-onity-
starts-to-shell-out-for-security-fixes-to-hotels-hackable-locks/)
~~~
fatbird
How they responded after public disclosure says little about how they would
have responded to notification with a deadline for public disclosure.
I understand the various incentives for Onity, and I think a great incentive
for them is, given six months to address the issue, knowing it'll be made
public, to take at least some proactive steps such as notifying large
customers or being ready upon public disclosure with a mitigation plan.
His whole blog entry is a lot of handwaving to cover up the fact that he never
even gave them a chance to do something anything like the right thing.
~~~
Firehed
He makes an important point though: security researchers have been used by
vendors as part of trying to go through the traditional process of responsible
disclosure. It could easily come off as blackmail[1]. Simply disclosing to the
public avoids that possibility, because the researcher was clearly not trying
to personally get something from the vendor.
That being said, I think this kind of thing should be covered by whistleblower
protection laws (I don't know if it's ever been tested)... although it seems
those are only enforced when it's convenient.
So while I think he may have reached the right conclusion, I don't think it
was for the right reasons. If sufficient protections for disclosers are in
place, this should be a relative non-issue (though it makes sense to adjust
the disclosure window based on the ease and risk of the vulnerability in order
to apply pressure for an expedited fix)
[1] Given there's no payout for the researcher other than having the
vulnerability fixed, it is conceivably not too hard to defend against. That
doesn't change the fact that they can be sued, which is expensive, time-
consuming, and stressful.
~~~
fatbird
The best protection for the discloser is simply to do so anonymously, which
shouldn't be difficult for someone like this.
Alternately, do so 'legal anonymously', perhaps by the EFF approaching the
company and saying "we have in our possession information on a security
vulnerability in your product. We want to give you information on it. In six
months this information will be made public. We ask for and want no
compensation or consideration at all."
That's it. There exist methods to do this safely; Daeken could have done it,
and didn't.
~~~
lawnchair_larry
No, the EFF doesn't offer this service, and given the volume of
vulnerabilities disclosed, it would be a huge waste of their resources.
I'm not paying a lawyer because you have broken software that I had nothing to

He missed an option: disclose privately to Onity's major customers, and give
them some time to assess the situation and deal with Onity.
~~~
daeken
Yeah, didn't consider that angle. However, that (much like Onity's original
approach to the problems) leaves the independent hotels in the cold.
Definitely a decent option, though.
------
paulgb
Where does US law stand on full disclosure? I'm aware of MBTA v. Anderson, but
are there still some grey areas?
------
gojomo
While fixing all the locks will be costly and time-consuming, perhaps a far
smaller number of specialized 'tripwire' fix boards can be sent to affected
hotels, boards which track (and perhaps report instantly by radio) attempts to
use the hack. For example, one such device could be added per floor.
Even if crooks only very occasionally trip the specialized replacements, they
would alert hotels to active exploitation, allowing either immediate
apprehension or timely review of security footage. Shifting the risk/reward
for criminals could buy time for a more complete but gradual fix.
~~~
daeken
Once you've already spent the time and money to pull the locks off the doors
and replace/add a circuit board, you may as well just drop in the fixed board.
That prevents the main vulnerability from functioning, though there's no fix
at all for the encryption flaw (but no one has exploited that, nor will they
in the near future, if I had to guess).
~~~
knowaveragejoe
Not only that, but seeing as the locks don't communicate in any way besides
the maintenance port, there's no way to know if they've been tripped without
reading them at some regular interval.
~~~
gojomo
The replacement board, in the hypothesized special 'tripwire' assembly, would
have added radio-reporting. You only need a few of these super-locks, randomly
added to the population of vulnerable locks, to catch any exploitation at
scale. That'd both curtail the losses and deter future copycats. ("While
you're rifling through the guest's belongings looking for valuables, security
is already on its way.")
------
kevingadd
Even if the risk for independent discovery was high, announcing it to the
public without contacting the vendor and giving them the opportunity to at
least prepare a response plan (even if you think the plan is inadequate)
ensured a thoroughly dramatic media response that made certain that anyone
with the slightest desire to break into hotel rooms now knew how.
EDIT: Yep, you're right. I don't know how I missed that given that I skimmed
the article twice. Sorry.
~~~
daeken
> The fact that 'contact Onity, then disclose publicly after a reasonable

That's the very first thing on the list. Quote: "The standard 'Responsible

ntoshev
I think practicing programming should be about:
1\. trying many new things
2\. in a very tight feedback loop
So, code little ideas, but make sure you start from the essence of the problem
- not the registration/login process, not the new API - start directly from
the part that's new and challenging and risky. In this way, when the idea
fails, you wouldn't have wasted time building support infrastructure for it.
Also, pick light and flexible tools for exploratory programming - dynamic

So, fair point. Keep up to date with technology, don’t become obsolete. Sure.
But I don't know about the metaphor. I mean, programmers do practice daily. If
you’re coding at work you’re practicing.
More to the point: if the author played in the NFL he’d want the cornerback to
do exceptionally well at game time, to practice daily, of course, AND to go
home at night and keep practicing to become a quarterback AND a coach because,
you know, got to keep up. My guess is that’s not what happens in the NFL.

Coding at work is certainly not optimized for practice.
NFL players do an exceptional amount of highly optimized training in addition
to their "work" of playing the game: [http://www.si.com/nfl/2014/12/10/tom-

No, you shouldn't _have_ to work a 40+ hour week and then go home and practice
to make a living as a software engineer. But if we want highly performant
programmers, we should figure out the best ways to practice (and probably
spend less--but more effective--time on production code to balance it all
out).

You're coming very close to identifying a major problem with our industry that
isn't likely to go away. Yes you absolutely do have to "go home and study" to
keep up as a software engineer/programmer. This is due to two reasons:
1\. Advancements in technology outpace us
2\. We're generally overloaded by management that doesn't understand what we
do.
As for #1 there isn't much we can do to change that, and who would want to?
But for #2 it's a major problem. In many cases our 40+ hours have to be filled
with coding because of the unrealistic deadlines that are posed on us from
managers who don't understand the work.
Most of us are managed by people who have no idea what we do. They want "more
more more" in terms of features and gizmos but haven't the slightest
understanding of what goes into it. Add in scope creep and wasted time with
meetings (that make them look busy) and that adds up to a long work week for a
developer. And when you ask for time to study or learn something new, the
response is "sure, when things aren't so busy".
This just reinforces my belief that you need passion to do this. You have to
love development so much you're willing to put up this stuff, work your ass
off and still want to go home and learn more.
~~~
kyllo
Yes and it's also because the projects you'll typically work on in a corporate
environment are like maintaining and adding features to boring CRUD apps and
your skills will atrophy if you don't actively seek interesting, challenging
work on your own time.

I would be interested to hear the opinions (or more accurately, experiences)
of developers regarding "practice." I'm beginning my career as a software
engineer this summer and I would like to become an "excellent" engineer.
Employable, of course, but also the go-to for knowledge in a subset of
computer science (let's say natural language processing, for example).
Given I have a very long life (hopefully) ahead of me, what would you say is
the best way to do this? Yes, coding is good, but is it the best way? I spend
a large amount of time doing side projects, but eventually I'll have a family
and other obligations, so I would need higher impact, less time consuming
practicing options.
An example of this I guess is how many expert violinists actually "practice"
for a surprisingly small amount of time because the practice is so deliberate.
What's the equivalent for us?
~~~
joe_the_user
I do martial arts and I program.
Nearly everything I do in martial arts is practice for the relatively few
times I might spar with someone.
I don't do any skills practice for programming. I've never met anyone who did
something equivalent to honing basic movement, practicing balance and similar
things.
Reading about the latest programming methods is a good thing and can increase
your repertoire but I don't think it's comparable to skills-practice in
martial arts or music or something similar. In practices like this, there are
fundamental skills that need to be in good shape to allow a person to anything
creative in the discipline (I have no idea why expert violinists wouldn't
spend significant periods practicing but I know little about that. I know that
most music requires significant practice of basic skills to achieve mastery).
My suspicious is that programming is an activity that is strongly connected to
the brain's language centers and so mastery of it on the skills-level is
simple and the problems with it appear on the judgment and understanding level
- which doesn't make it easy, rather gives it that extraordinarily hard
quality that we programmers are familiar with.
Also, most skills-practice disciplines are performance arts rather than
production processes. Machinist and auto-mechanics also have high skill levels
but like programmers they are obligated to show some significant
accomplishment for their entire time at work. We can contrast this with a
musician or other artist, who if they give an amazingly beautiful performance
once a month and have it recorded is considered remarkably successful. In
contrast, a programmer gets few accolades if she can just "be a great
programmer" for an hour a month - what is instead considered with programmers
is their entire output, which puts an entirely different series of pressures
and constraints on the programmer.
~~~
kyllo
Cool, what martial arts do you do?
Brown belt in Brazilian Jiu-Jitsu here. I love coding for some of the same
reasons I love training and sparring. It's endlessly complex, so you never run
out of new challenges.

This is good advice, but it's a bit hard to act on. How does one know when to
leverage their existing skills to build something vs spending time learning
something new and using it to build something (which might not pan out due to
lack of experience with that technology, and which will certainly take longer
than using what is familiar)? For me, the biggest investment is that of
time... and while he provides ideas for small things to do, in the end one
really needs to use a technology to grasp it (which he does say).
I'm a beginning programmer working on a small team. We won't be hiring anytime
soon so many of the things he suggests aren't options. I'm lucky in that I've
been able to learn a lot of things across the stack. However, our main
language is Perl, which isn't the most marketable language anymore.
I have an idea for a useful little site -- something that will look good on a
resume, but not something that I can imagine becoming a big money maker of any
sort. Do I use my main strengths, my familiar technologies (such as Perl and
SQL), to write the site? Or do I choose something that might be an up-and-
coming technology (like Node.js or Clojure) even if I can't really find any
jobs in my area for them?
I do love learning. I spend downtime at work learning new things, but my time
outside of work to actually build stuff is limited. I'm getting a bit burnt
out on learning new languages and frameworks... I've wandered between Perl,
Elixir, Haskell, Clojure, Racket, Javascript/Node, and any number of
frameworks for them. I just want to make something solid, but I'm worried that
using my Perl skillset will be more of a short term than a long term gain.
I know there's probably no easy answer to this question. But it seems to me
that it's better to have made something and launched it (even if it doesn't
use the sexiest tech) than to have something half-finished stagnate because I
don't have the time to learn the ins and outs of the quirks behind some new
tech. Does anyone have any insight into handling this? Thanks.
~~~
sleazebreeze
I've had the same quandary as you. Mainly work with Java and Javascript at
work, so I wanted to add a purely functional language. I flirted with Haskell,
Scala, Node, Scheme and Clojure and eventually settled on focusing on gaining
a better understanding of functional programming with Clojure because it has a
familiar platform (JVM), syntax I can understand (sorry Haskell and Scala) and
it seems like it's going places.
Last year, I maintained a focus on Java and JS because I'm still intermediate
level with those and didn't want to distract myself with other languages and
paradigms. That was a good choice.
For this year, I've made a commitment that any side projects I do, I do in
Clojure. I cheated and started in 2014, but I am liking this way of focusing
on a language for a year and doing everything in that.
Maybe once I have more familiarity with more languages, I will feel more
comfortable using the appropriate language to solve a particular problem.
However, isn't that part of learning? Using a hammer on nails, screws and
bolts and figuring out what the hammer is good at and what it isn't?
------
JeremyMorgan
Great article. This is something I've said pertaining to interviews for years.
There has to be advancement in the skills. Doing something every day is not an
indicator of improvement.
In fact, sometimes it can be worse. When someone says "Call this person now!
he/she has been writing C# for 10 years!". That's great and all but have they
been improving their craft over that 10 years, or getting enough work to not
get fired? There's an enormous difference. And many times I would run into
folks who sunk into a rut and did the same thing for 10 years basically
"coasting". They make small incremental changes in what they do every day, but
weren't out seeking ways to drastically improve.
Programming is different than many other fields simply because it requires
passion to survive. If you look at learning new things like "Ugh, I have to
learn ___", eventually you'll start slipping and end up hacking PHP Wordpress
installs somewhere for subpar wages if you're employed at all. If you seek out
new things to push yourself because it's enjoyable keeping up is intuitive and
easy. Even stuff you may never use for your job can teach you new ways of
thinking.
Now if you'll excuse me I need to go back to playing with RUST.
~~~
guelo
With the speed of technology changes I think it's pretty hard for programmers
to get stuck in the exact same rut for 10 years.
Using your example of C#, there has been huge changes in the last 10 years to
the point that it's barely the same language.
Even if you imagine the most staid company that refuses to upgrade their tech
stack, the last 10 years has seen so many changes in the web and mobile that
it's hard to imagine that there hasn't been some pressure on even the most
unmotivated programmer to learn new skills.
~~~
JeremyMorgan
That's why I mentioned iterative changes, such as the changes to C# over the
last 10 years. Just because they started using generics at some point doesn't
mean they've been learning anything to drastically improve their code.
It's very easy to sit at a company building calendar apps for ten years and
fall behind the rest of the world. I see it every day.
------
peterwwillis
This is a _very_ long way of saying: you should learn new skills, and practice
the skills that you think will be valuable by the time you need to get a new
job.
Practice isn't rocket science... heck, just practice different kinds of
programming. You'll naturally improve at everything because it all relates to
each other. To borrow from his football and music examples, even practicing
dance will make you a better football player, and so will playing the drums
for a cellist.

are in mentality and artistry. It's no wonder that I enjoy both :)

Almost all the big EC2 outages have been due to EBS, and you have to pay extra
for it as well. Netflix steers clear of it [1].

this new one) make using EBS mandatory?

~~~
crb
Two reasons come to mind:
* the failure rate of an EBS volume (assuming a bug-free EBS software stack!) _should_ be less than any one spinning disk
* these machines don't have disk space set aside for copying the root volumes to them from S3 to boot. (There's a 10GB limit, and to allow for this to be somewhere, you'd have to have another SSD, or partition the existing ones.)
There's a good blog post about it on Rightscale:
[http://blog.rightscale.com/2012/11/02/new-ec2-instance-
types...](http://blog.rightscale.com/2012/11/02/new-ec2-instance-types-and-
coordinated-failures-in-the-cloud/)
esh's "You Should Use EBS Boot Instances" also lays out a number of good
reasons to use EBS for boot: <http://alestic.com/2012/01/ec2-ebs-boot-
recommended>
You at least have two 120GB ephemeral SSDs to play with when you're running -
a luxury you don't have on the new M3 classes.
~~~
Dylan16807
It's not really the rate that's the issue here, it's correlation between
failures. The chance of losing a third or more of your machines at once is
enormously higher with EBS.
Partitioning a disk should take seconds; I don't see why it would be an
impediment. As it is, someone can do it themselves but now it'll be a custom
job and less reliable.

One way to scale Firebird Database is to put it on memory virtual disk or
ramfs
On linux i can mount a partition in memory (Install ubuntu/debian)
sudo mkdir /mnt/ram sudo mount -t ramfs -o size=200G ramfs /mnt/ram mount to
show you the partitions mounted
and then move your database into the ram partition
cp -rp /var/lib/firebird/2.5/data /mnt/ram
That large instance could help you with the Firebird cache settings also the
extra SSD could do wonders
Inspired by the stack overflow big fat server architecture

jacques_chester
Well, two things with that. Three really.
First, does AWS allow ramdisks? It's been a few years since I tried to mount a
ram disk on Xen, but it was not possible at the time.
Second, most databases are smart enough to shuffle stuff into RAM for you,
starting with indexes and commonly-accessed tables.
Third, the "D" in ACID stands for "Durable". If you want an in-memory store,
use an in-memory store. RDBMSes do sorta kinda rely on the assumption that
stuff written to disk is _actually written to a disk_.
~~~
mariuz
Yes it AWS allows ramdisks , here is the output from a machine
root@ip-amazon-ip:/home/ubuntu# mkdir /mnt/ram mount -t ramfs -o size=2G ramfs
/mnt/ram mount ramfs on /mnt/ram type ramfs (rw,size=2G)
There are the cache and memory settings Fore Firebird but is better to put the
main full database on the fastest storage and that is RAM for the moment
In Firebird we have a nifty feature called Shadow that creates a life
snapshots of the active database (Think of it as Replication in real time) so
you can activate it and keep a safe database on the SSD/HDD

RAM isn't a cure all for big data applications and presents its own set of
challenges. The largest issue is with traversal and data access latencies
simply because of the virtual memory management overhead that is required.

Some time ago (mid 2011), I was trying to use an AWS 64 GB machine for some
largish work and discovered that I couldn't actually allocate anywhere near
all of the 64 GB of RAM I was supposed to have access to. As I recall, writing
a simple C program to do binary search to pinpoint exactly what the max amount
of memory I could malloc was, it failed somewhere around 34 GB – so just over
half of the memory I was supposed to have access to. Makes me wonder how much
of this 244 GiB you can actually use when you spin up one of these machines.

The sad thing about the banker's bonuses is that if they honestly tried to

_lost_ money last year.

If Matt Taibbi wrote an article on a stick of poo and mailed it to me, I'd
still read every word.
~~~

I find the idea of Matt Taibbi writing articles made of poo to be
metaphorically appropriate.
It depresses me that these screeds find a place on this website. It should be
obvious, by the tone, polemical nature, and carefully arranged blindness of
the above article, that no valuable or contextually useful information could
be got out of it.
It further puzzles me that it has become trendy to attack the financial
market's most successful and profitable large institution. This proto-Marxist
sentiment has no place in a free society. The only people forced to trade with
Goldman were taxpayers financing the bailouts, and you know what happened to
them? They got all their money back _plus twenty-three percent interest_.
~~~
Snark7
Actually Matt Taibbi is, apparently, one of the very few members of the press
to have the intelligence, motivation, and opportunity to attack Goldman
repeatedly. Everyone else is on a 24-hour news cycle, and as far as I can
tell, Blankfein taking the $9 million bonus effectively defused the situation,
especially after it was leaked that his bonus could be $100 million. Setting
this up and getting the press to report the relatively low bonus was a
brilliant PR coup, and it appears to have worked.
That being said, I don't have any issue with his efforts at muckraking - I
believe in freedom of the press after all.
~~~
cynicalkane
That makes him a fanatic, but it doesn't say anything about his correctness.
The other thing is that, though I'm sure Goldman's decision was partially PR-
motivated, it's what they should be doing anyway.

rrhyne
Pulling back on Loyd's bonus was a substance-less ploy. They received over
tens of billion in bailouts, plus loans at 0% on MY dime, plus 100% in payouts
on 5.9b on a bankrupt company. Because if this, they posted 13b in profits and
paid out 16 billion in bonuses.
Do the math and they should be out of business. Instead our corporate
socialist state (fascism) paid those bonuses with my taxes.
