It would be nice if we could at least undo downvotes if an undo for both is out of the question. I think everyone has accidentally clicked the wrong one at least once and downvote is the one that does the most damage.
There are countless flaws in this comparison, but the one that stands out to me is the simple buying vs renting issue. They sourced screws that would be permanently installed into something. They rented a couple hours on a server.

Renting is always cheaper than owning. That's a pretty universal rule. Complain about the red tape all you want, I have also felt the burn of the "approved supplier" list. That doesn't excuse an extremely faulty comparison, however. It just clouds the issue.

I understand coming up with a better comparison would be a little more work than the immediate but completely faulty on-hand cost of the server instance they spun up, but I know the cost of the computer I own and the cost of a server I rent and I wouldn't use them to make a comparison just because I'm too bothered to come up with a real comparison.

There is also the issue of the fact that the $2000 number was pulled out of seemingly thin air, the possibility that they use approved suppliers to avoid the issue of counterfeit or sub-standard parts, which have killed people when installed into regular things like bleachers that stay on the Earth. It's the freaking Canadarm, god forbid we splurge now so we don't waste millions later fixing it or kill someone. When the end result of the materialized idea is it's going to be launched into space, the costs probably aren't so black and white.

Interesting story, but with so many variables unaccounted for I have a hard time gleaning any sort of lesson from it. Other than the fact that building a piece of equipment that will be launched into space involves a fair bit of red tape, which I was already aware of and am honestly kind of thankful for.

I keep coming back to this essay called "Can a Biologist Fix a Radio?": http://protein.bio.msu.ru/biokhimiya/contents/v69/pdf/bcm_14...

The thing that keeps coming to mind is that it's easy to hand-wave pseudo-understanding of systems using enough jargon and vague diagrams. And if you use enough jargon and cloak things behind complex methodologies (the mechanisms to even begin investigating how cellular machinery works are enormously complex) it's easy to hide a lack of understanding. And I can't help think a similar sort of problem exists in software. The tools and terminology we have for explaining and understanding software systems leaves a lot to be desired, and one of the ways that is revealed is in the diagrams we use for describing systems. At a fairly fine grain we can use UML diagrams, but these tell us almost nothing and in complex systems simply become a giant hairball. Typically we end up describing a system as a series of layers, or as an interconnected set of services, but I can't shake the notion that such diagrams are too much like Figure 3a in the essay above than like 3b, they are the crudest sketch of a system, they don't touch on the nature or interrelation of the components.
I would strongly recommend tmux over screen to anyone, if it is available on your platform.

Screen's development is basically dead. Tmux is under active development, and the developers are responsive and intelligent.

Tmux is sudo safe, where screen is not.

Tmux lacks screen's ability to connect to serial devices, which is used by some sysadmins and router monkeys like myself, but that's okay.

Tmux also sucks for tee-ing it's output to a log file, which screen does nicely, but this will probably be fixed some day.
my thoughts exactly.. most of the traffic i care about i can already monitor with chrome's network tab.
Whilst I applaud the efforts of PyPy, I've always been disappointed with the performance benefit it's given me with real world code.

Specifically:

* PyPy Dict performance is very slow (slower than Cpython). A lot of the code I need to write that is cpu-intensive python code processes data (from stuff like logs) into various data structures that use dicts. Pypy is rarely more than 10% faster and sometimes slower.

* The memory management/GC can be bad. I've seen the same code that runs fine on cpython end up using excessive amounts of memory (and causing out of memory issues etc) with PyPy. Again - this is normally involving complicated data-structures.

On about 10 occasions now I've had CPU bound Python tasks, then I've tried to use with PyPy and never had > 20% performance improvements. Which is a big contrast with the benchmarks.

Is it just me? Or have other people had similar experiences?

I can't really agree with you that every other car in this price range (a huge $90k for the performance edition) is mediocre. There are a lot of simply amazing cars available if you are willing to spend that kind of money on one. Hell, there are amazing cars available for way less than that.

I don't know if it's related to the larger trend, but I do find myself frustrated when the speaker lineup is finalized late. No doubt, there's logistical reasons for this, but for me, the quality of the talks is often very hit and miss, even when I do know who is attending. The Hacker News brand alone isn't enough to draw me and I'm not much of a mingler, so I rely on the speaker lineup to see if I'll go.
This is more poetic, but I think the submission does a better job of describing depression.
Is it really that good or does it just have a huge benefit because its electric ?
As a car, i dont believe its better than a similar specced 5 Series BMW or E class Merc. Yes its electric and has amazing performance, but it will also not take you very far which imo is a big issue for a GT class car.
Indeed.. but $70 is a hard pill to swallow for a pretty file comparison utility. I was thinking somewhere more around $30.

This hits home. I've been there for about 14 or 15 years. Not so long ago I realized that this was a form of implicit emotional blackmail, which is a very hard situation, because, while it certainly works indistinguishably from standard emotional blackmail, it's not done knowingly or maliciously. I've ended up feeling like I don't own my life... again, not a good situation to be in.

I got the opposite lesson out of skating since we had to negotiate with cops all the time.

It's 3 in the morning, you want to skate some plaza, and the only thing stopping you is the cop on his beat. As soon as I found the cop, I'd go ask him if skating here was fine, or if somewhere else was better.

The cop that gets stuck with a city beat at zero dark thirty is either the n00b or did something stupid and isn't super happy with Authority. On top of that, the only people awake at this hour are drunks, bums, and skaters. Given a reasonable skater, which one would you prefer to talk with?

I knew that if I was the least irritating of the options, I had good chances at being cut some slack. So, there's no way I would front some attitude or do anything that would deviate from the "nice kid who happens to be on a skateboard" image.

Filters are the opposite of useful since they drop so many people who could make a positive impact if you structured the encounter properly.

You shouldn't feel guilty about the dice thing. I think us who live at developing countries on average have it easier when it comes to depression. Our problems are easier to identify and we sometimes even use them to explain our other unrelated problems. Besides we know that developed countries have managed to fix them so there is hope that we might be able to, too, giving us some lofty-looking goals to achieve.

That statement is a far cry from saying that every other car in this price range is mediocre. Generally, $90k cars are pretty great. The Model S might just be slightly better due to, say, the battery pack helping weight distribution.

This is also just one review. It's not like this is suddenly the world's universal judgment of the Model S.

Psycopg2 - Well, it's just a client library - surely you will be making sure your client matches your server's version (whether that's local or a clust or whatever)? Sure your system will likely need Postgres headers installed, but why is that an issue? Actually, let me just check that. e: Yeah, you need libpq-dev installed, but I fail to see the point here? You need to make sure you have python-dev and a correct version of Python installed, too.

Stop whining about .io being a "hipster" TLD. Hipster is just a slanderous term for someone whose interests aren't exactly aligned with yours. Live with it.

.io is great because it has not been polluted by squatters and excessive usage over the past 20 years. The price of .io hopefully discourages wasteful registration, and it's a TLD used mostly by the tech savvy community, so it won't get polluted too soon. If you're in the tech community and you want a nice domain name, go for .io.

What's New in Scratch 2.0
I love the new ST3. The speed improvements are really compelling. I use it as my default editor for simple text and HTML editing. The stability seems great, so I would not let the beta tag put you off trying the new version. I keep ST2 handy for the more complex tasks.

The main hurdle before I complete the switch is to see all the plugins available for ST3. At the moment using Package Control it is still too much guesswork to figure which plugins are ST3 compatible or not, and many plugins (including Package Control) have to be installed manually. For me the following plugins are still broken (errors on loading the scripts at startup):
Http Requester, Tag, SublimeCodeIntel, BracketHighlighter, SublimeLinter, FileDiffs, Alignment, Theme - Soda

ST3 itself is great, I just hope the 3rd party plugins get on board quickly.

True. My worry is that this is just the v0.1 and it is the shape of things to come. Desktop CNC milling machines are also getting better rapidly and can make metal parts. ( http://www.kickstarter.com/projects/otherfab/the-othermill-c... ).

Designing this gun was clearly an asshole move, but how do you prohibit it now? Cory Doctrow said something along the lines of DRM is "allowing a general-purpose computer to run any program except for the ones that I don't like". (http://boingboing.net/2012/08/23/civilwar.html )

A 3d printer or cnc mill that can make anything "except for the shapes that I don't like" is equally laughable.
yes. "eventually consistent" is not "consistent" in cap terms.
That's a different issue. Smuggling a small bullet past any security has got to be way easier than an entire gun.

consider the network of nodes separating (partitioning) into two groups - each internally. connected, but unconnected from each other. then messages from one group never reach the other group.

so partitioning still has the sense of "splitting" - it's just that the explanation focuses on messages rather than the network.
Weird piece.

It says things like "[punishment] would send a confusing message to Youtube uploaders everywhere, so it will be interesting to see how the German courts approach this matter." In Germany there is the so called "Recht am eigenen Bild" which means you cannot just film random people and share the images or even exploit them for money. This is a law specific to Germany. Its application does not mean much for "Youtubers everywhere".

I strongly support this as a matter of privacy. Gawking is creepy.

Actually, yes.

The transaction is stored, and fowarded later. It's a variant on the Card Number + Impression that used to be common place 20 years ago, and Card Number + CCV that is still common place in locations with intermittent/no connectivity.

The prime example of this being done electronically is on planes, they have been accepting credit cards a large number of years before connectivity was possible.
I'm not aware of a direct comparison of Perl and PyPy. However, for a paper I co-authored, we put together an experiment with various languages and VMs, using the language shootout plus a few other benchmarks:

http://tratt.net/laurie/research/pubs/files/metatracing_vms/

Cross-langauge benchmarks are inevitably synthetic, and synthetic benchmarks can only tell you so much. It's important not to over-interpret them. But they can give you a rough idea of what's going on, at least in some circumstances. If someone wanted to add Perl to the experiment set, I'd gladly accept a patch to the benchmarking suite.
Adolescent 17-year-old here, it is actually my greatest fear. But I do not have the healthiest mental state.
That's not true for Cassandra. Cassandra allows for stronger consistency, if you only wish to trade some performance for it. If R + W > RF, you are guaranteed to get at least the latest successfully written value. There may be only a temporary inconsistency: during the write some nodes may see the old value, but some other may already see the new value.

Being an introvert is a vastly different thing from what OP described.
Extrovert enjoy social interaction and need it as part of their "energy", while introverted people will see the same kind of interaction take a toll and thus need time alone. Carl Kingdom explains very will what introversion is about [1]. Also, remember that introversion / extroversion isn't a binary trait but a whole spectrum of behaviours.
If OP lacks empathy and feels the need to exploit other people to his own benefit, then chances are that he has psychopathic traits. That doesn't mean he's a serial killer or that it should be taken as an insult. Of course he can have more information by consulting a licensed practitioner.
