What precisely do you gain by having a narrow focus? What do you lose by having this story on the front page for half a day?

What is essentially wrong with being off-topic?

Honestly, I think this place would be awful if it only had the focus you intend. The advertising nature of posts about this new project or that startup frequently crosses the line between informative and irritating.

This is hacking in the old jargon file sense (http://www.catb.org/jargon/html/H/hack.html) or the MIT IHTFP sense (http://hacks.mit.edu/).

Automation, spoofing and security breaking tools are improving all the time. It's important that it's security researchers (and students) who are driving the arms race, not the criminal element.
I more or less agree with this take. Windows 7 was good enough that a lot of people won't have a reason to upgrade, but as Windows 8 tablets become more common I think we'll see a "halo effect" on desktops. Having seen it running for a few months, there are a lot of nice things about 8, and once you get over the Start menu there aren't many negatives.

And new computers will come with 8 installed, so that's some pretty significant adoption right there.
I really wish this was an as-shipped feature with OpenSSH. Even if it is the config file being able to have multiple Hostnames to try for a Host.

That way I can just specify two hostnames/IP addresses to try and ssh can automagically do the right to to get to an internal machine depending if I am at home or work.

The reason everyone asumes HTML5 apps can't work on mobile is because how awful UIWebView is on iOS. Apple really need to explain how limiting JavaScript speed in WebView makes it anymore more secure.
Wow, this compiles fast. And the Flex and Bison files are there. This seems hackable. Nice work!

My only questions are (they are always the same with any purported sed/awk "replacement"):

1. what was the problem you were trying to solve where sed and awk failed you, and

2. does this program operate line by line or does it read entire files into memory?

I had to deal with some JSON a while ago and threw together some sed like this just so I could read it:

sed '
s/,/&\
/g;
/^$/d;
s/^[{][^}]/\
&/g;
/\"/s/,/<##eol##>/g;
s/ *//;
' |tr '\012' '\040' |sed '
s/<##eol##>/\
/g;
s/\[/\
&\
/;
s/\]/\
&\
/;
s/, /, /g;
'

But any difficuly I have dealing with JSON I attribute to the pervasive use of JSON, not sed.

I don't really understand why people are so excited about 3D printers when CNC mills are cheaper, more precise, and work with any material from balsa wood to granite (including metals and plastics). (I also don't understand why 3D printers are a "revolution", when computerized production has been around for decades and everything you own had a CNC mill involved at some point in the production process.)

I've used a 3D printer before. It was fun and it didn't produce a mess, which was nice, but all I have to show for it is some ugly chunks of ABS that look kind of like a child just had some fun with very melty crayons. One time when I was 5, I made a snowman out of hot glue. That's still beyond the range of $1000 3D printers.

The only reason Windows XP "suddenly" became popular is because the next version of Windows that came out was so bad that everyone finally capitulated.
I know that.

In the US, a market economy applied to healthcare limits the demand. Yet a lot of money gets spent uselessly in healthcare- and this happens even in government run programs.

People want more of everything, but there are physical limits about what is possible.

Even if each person get less per dollar than in other countries, for some reason I don't fully understand there is a high demand of healthcare, and also more distrust of an expert run system (like QALY evaluation in the UK)

It's not just an inelastic demand - it is more like a weird moral hazard scenario, or as if healthcare had increasing marginal returns for people utility function.

In this situation, replacing the market system by a government program might cost less in the short run - I fully agree - but much much more in the long run if demand is liberated.

That's because healthcare is not just like any usual good where you have reducing marginal returns, and it will be made worse especially after it has been "shown" that the endless money supply of the government can provide healthcare to anyone! ("shown" not as a valid proof, but as "noticed" by people who can cast a vote)

In the long run, I believe it will end up costing much more by this self perpetrating demand, up to the point it actually damages the economy.

A dollar spent on healthcare is not "productive" - healthcare is an investment with a negative interest rate. You can only put more money to try to keep your capital - but in the end you still die (maybe that's the reason for the increasing marginal returns - you need more and more of it).

It's bad enough when a country make debts not for investment but for consumption, yet it's much worse to make debts to "invest" in something like healthcare - with a negative interest rate

European countries are in for a bad day when they won't be able to patch the system anymore. In France IIRC the social deficit was around 100 billions in 2008 - much more than the government budget - with a 10 billions deficit just for healthcare. Now it's 160 billions in 2012 - http://online.wsj.com/article/BT-CO-20121001-707300.html]

Almost doubling in 5 years - let's round that to 60 billions per 4 years for a country of 60 millions persons.

Let's make some quick calculations.

Do you have any reason to think than, in a country with 5 times more people, and spending 16% of its GDP on healthcare instead of 9% in France (not sure about the precise %, but it's around 33% more), all others things being equal it won't create at least a 6051.33 ~ 400 billions deficit in 4 years?

(and that's a baseline scenario with an identical efficiency - with the highest cost of healthcare in the US, which can't be slashed in a day, I'd expect something at least like a 1000 trillion/5 years - and that won't be a stimulus, except for increasing demand)
Surface might make less money than an OEM license for RT would have, but there's no way another company could drive the tablet sales that Surface will.

With the increased adoption, their cut from Windows Store software sales should make up for some initial shortfalls.
JavaScript execution speed is no longer a major limiting factor on mobile. In terms of UI JavaScript execution speed will help you if you're using jQuery (or any naive animator) to animate 2d CSS properties. The DOM, 3d transforms, etc are the real pain points.

As bad as UIWebView is, it somehow manages to be the best webview out of any mobile OS.[1]

[1] as for BB10, I'll believe it when I see it.
Having worked at Salesforce I can say they take _forever_ to move on anything. When I left the company two years ago they were just starting to talk about Postgresql as a option to replace Oracle..
Don't like the title, should probably be more like "Be flexible with your consistency"

You can't be inconsistent and learn say a language (programming or otherwise), or even learn how to be a good entrepreneur, you got to be consistent and keep at it, just be flexible with the information that you receive and be willing to change your ways if you need to.

Exactly. Car industry used this naming scheme for a while now. E.g. BMW 528: 5-series with 2.8 L engine. And then you specify a model year.

Do you think that perhaps the recent "craze" to become a developer is not founded on solid group? Are people wasting their time and money? Definitely feel there is some merit to Peter Norvig's comments.
Growing up I was one of five kids and my parents could do this if they wanted, as we were aged 4-16. I think I'm a few years from this being possible as my 5 year old daughter is in a jealousy stage with my 2 year old son, so any time together alone turns into an issue every time.
I used hacking in the exact same sense. I applaud their initiative and hacker mentality.

But, it still doesn't change my opinion that it's cheating, and as user nthitz said, it's just a case of students being sore losers.
All this energy to figure out what people will think on a particular day. And so much energy spent trying to manipulate their opinion as that day approaches. We should be figuring out how to make the system better respond to what people think all the time, just as entrepreneurs do in any industry.

Yes, people try to influence us when we are at decision points. But many things are about long term relationships and trust. Shouldn't we be striving for that?

Its a bit absurd that we cannot change our minds later. Wouldn't having that ability make politicians more honest?

I'd prefer to see proportional representation in both the legislative and executive branches (Switzerland does it) PLUS the ability to change who represents me whenever I want. We have much better technology now, so shouldn't we use it to make our electoral decisions more effectively?

Yeah. Enterprise users are going to buy Windows 7 tablets instead.

Sarcasm aside, (some) enterprise users are going to buy tablets, and they're going to have Windows RT. Whether they adopt 8 on the desktop is a separate question, but if there's good uptake of RT that will give it a kick.
So basically you live like a leech or a hobo, bumming on other peoples couches. How "Zen" of you, "dude".
Changing your mind and being inconsistent are not the same thing. Stupid article.
Concur. I lived out of a suitcase for years. It was quite handy back when I was a student and moving from place to place every 4 months.

But then I moved in with a girl after school and all that went away, we needed to buy kitchen shit, dvd shit, bedroom shit, shit to hang on the walls, stuffed animals from thinkgeek that look like sushi, etc.

I know I'm going off on a tangent but I'd be weary on putting anything on a Belarus domain name. If you're not selling to or dealing with Belorussians directly, you're most likely not affected by it but a country that can do this – http://www.bbc.co.uk/news/world-europe-16407235 – should be treated with caution.
What about profits from the app store and accessories?
I recently visited Microsoft innovation labs in Mountain View and they were really touting how cool Windows 8 would be on desktops and tablets. I've actually been using the release candidate version on a dual boot laptop with Ubuntu for the past couple of months and have not been impressed or greatly inconvenience. I did ask the presenter, a Microsoft developer, how I could easily shutdown my computer as the shutdown button is now not easily accessible as in Windows 7. His answer annoyed me as he gave me three options on how to do it but didn't address the "easily" part of my question. This may be a pattern with Microsoft, lots of feature but limited simplicity.

One's ability to use simple words to describe complex concepts is a function of not just understanding of the concept itself, but also mastery of the language. Consider that many (most?) of the research papers you've read were written by non-native English speakers. In my experience, people who are native English speakers have an easier time being both precise and concise.
I thought this was going to be about Surface.
I'm of the opinion this is always newsworthy. Its completely outrageous how huge multinationals earning hundred of millions in profit can get away with paying less tax than mom and pop businesses. I don't see how "the practice has been known and used for many years" means that that means its case closed. Maybe there is a minority of people who want to discuss whether this makes sense in the current context and in the constantly changing fabric of business ethics. If this is not interesting to you, then fine, ignore it. But please be assured that some people do find it interesting.
To this day, a large fraction of companies has ignored Windows Vista and 7, and is still running Windows XP. The upgrade to Windows XP went smooth by comparison.

I think one major reason why XP succeeded was that it actually made a lot of difference. Compared to Windows 98: Way less crashing, way more stability, and a much better platform to make serious software on - thanks to a modern 32-bit kernel with proper segregation between userspace programs, which finally became widely available and tested.

What does Windows 8 bring over Windows 7 that justifies an upgrade? Small incremental updates don't count, Windows 7 has those too (over XP), yet it's still far from universally adopted after over 3 years.

(Now my lens may be colored with my view that convergence between laptops and tablets is a stupid idea, so I don't really consider that as an actual advantage of Windows 8.)

I have been thinking about this issue a lot recently. Sometimes clutter seems unavoidable, such as when you want to learn or do something new. When I first got into photography, I started off with one DSLR and one lens. Then I kept adding lenses. Turns out I also need to clean the sensor since dust accumulates when you change lenses, so I ended up getting lens cleaning kit. Next, I had to upgrade my camera, because it was not sufficient for photoshoots (got invited to a few events non-professionally). Then you got to pay for websites, online storage, this and that. And then you get a bag, a tripod and the list is endless (I have been postponing buying the tripod). There was also a ripple effect. My laptop display was not only short for image editing, but it was displaying colors incorrectly. So I had to get a new monitor, and I had to spend extra time researching whether the colors will display correctly or not. All these add up. Sometimes I just want to sell everything and get one camera and one prime lens, but I am afraid of "missing out". May be thats not true. I haven't found the alternative. But for what its worth, I have had a good journey so far.

If one wants to reach a higher level than an amateur, it looks like extra items are unavoidable. Similar arguments go with say learning oil painting or say charcoal sketching. When you are a programmer, would you prefer to work with a single laptop or with an external keyboard+mouse+large monitor?

Shouldn't the last sentence, "The benefits of telling the truth far outweigh the cost of lies" read "the ratio of benefit to cost of telling the truth far outweigh the same ratio for lying"? Weighing the benefit of one thing against the cost of another seems like a non-sequitur.
What a ridiculous article. So there was negativity about XP that turned out to be wrong. What about the negativity about Vista that turned out to be right?

And how about considering each case on its own merits? Even aside from the product itself which changes, the competitive landscape is nowhere near what it was in XP or Vista days. A failure (Vista) back then was a minor inconvenience. A failure today would be different.
XP was great. There were so many worse versions of Windows. Think about Vista, and ME.
i think that's the clearest answer i've seen. really, it's pretty much equivalent to the other answers, but at least for me it's by far the easiest to grasp. although i guess that may be because the idea is simply becoming familiar after reading the others.

the best "high level" explanation, i think, is that you are compressing the sorted numbers, which are therefore not random, and so concerns about the incompressibility of random streams are completely irrelevant.
I've gone the other way - done away with TV and collecting things so that I can spend more time being social. I have more money and time to spend on going out for dinner and drinks with friends, time to play online video games (social to a very fine degree I guess, but better than passively watching something on TV), and time to take my dog to the park every night (rain, hail or shine) where I talk to other doggy people and my dog gets some Doggie Facebook time in (sniffing other dogs behinds).

To me, being social is a huge driver of happiness and contentment. If you want to escape the pursuit of owning things - turn off your TV for starters.
it is amazing you think of it as cheating. if these guys really wanted to cheat we would just max out the extra 25 gigs and get it. We had already gotten 15 gigs legitimately. We aren't insulting the goodwill of Dropbox, we just think its fun to be atop the list despite having a student body of a 5th of what the other universities have. It is also classic tongue in cheek that Ben Bitdiddle and Alyssa Hacker were atop the list. This was a benign prank and was done mostly to amuse. More than the hack itself it was just the timing that makes this hack memorable. It was hardly a non-trivial hack. MIT was leading the space race a few days ago, and then we exhausted our student body and i find it more amusing than desperate to come back in the lead like this. And you know what, somewhere in the offices of dropbox drew and arash are probably smiling profusely and proud of their alma mater.
Because that will probably impact certain politicians and other "important" stake holders who benefit from these tax laws as well.

In my opinion, every democratic country should make the following change to their laws: Politicians cannot own, or have a stake in, any commercial enterprise. Needs to be a bit refined but you get the idea.
The $499 price means Microsoft will not make any real margin on the Surface.

So Apple is making a killing selling the iPad for $499 but Microsoft is making no margin on the Surface RT at the same price? Is Apple's supply chain really that much more efficient? If Microsoft can't even make money at price parity with Apple what chance do they have in this market?
This article dodges (willfully ignores) the every-other good-bad release schedule that has tended to be the pattern of Microsoft (and Star Trek movies).

The original point of P2P was that those costs are both sunk and not your problem.
I think the main point there was that unless you check 'promises' given to you from other APIs and applications you can't rely on them conforming to the spec.

As authors of Promises/A-consuming libraries, we would like to assume ... that something that is "thenable" actually behaves as a Promises/A promise, with all the power that entails.

If you can make this assumption, you can write very extensive libraries that are entirely agnostic to the implementation of the promises they accept! Whether they be from Q, when.js, or even WinJS, you can use the simple composition rules of the Promises/A spec to build on promise behavior...

Unfortunately, libraries like jQuery break this. This necessitates ugly hacks to detect the presence of objects masquerading as promises, and who call themselves in their API documentation promises, but aren't really Promises/A promises. If the consumers of your API start trying to pass you jQuery promises, you have two choices: fail in mysterious and hard-to-decipher ways when your compositional techniques fail, or fail up-front and block them from using your library entirely. This sucks.

Re: "new computers will come with 8 installed, so that's some pretty significant adoption right there."

I don't know a single corporate IT department in the Bay Area that has committed to a full-scale Windows 8 Deployment in 2013. My estimate is that 75%+ of new computer sold to enterprises (everywhere) in the First Half of 2013 will ship with Windows 7, not Windows 8.
In fairness the negativity of Vista was also wrong.
Tom Ptacek certainly made a good case that Google's politics (more precisely, the politics of a few individuals on the relevant team) are informing their search results on occasion:

http://news.ycombinator.com/item?id=3426570
The biggest risk that Windows 8 brings is that it's not just a no brainer upgrade. It requires training, it requires consideration of the costs and benefits. And once you are on that road then you are on a road that could easily lead you to non-windows alternatives. iOS or android tablets, linux workstations, etc.

And all of this because MS was too cocky and decided to go all in on metro instead of trying for a smoother, more gradual transition.
Ask 10 random users how they shutdown their iPad. I suspect that 9 of 10 will tell you they close their cover on the screen. Press them and say, "no, how do you actually shut it down". I suspect you'll get blank stares.

Most people never need to turn off their devices. Most people probably turn off their machine when there is no need.
