Sergey Brin Fools Them All On a Quiz Show Back In 2000
We are just now tapping on the spatial dimension of wireless channels; up to now we have just used frequency, time, and polarization for orthogonality. Spatial processing allows theoretically unlimited (bounded by computation, solved by Moore) channel capacity. At the same time, we are beginning to use the available channel resources more efficiently with cognitive radios, which allows much better spectrum utilization. Today, with statically allocated spectrum use, I'd guess that less than 10% of allocated spectrum and time is in active use at any time.

However, this system also blunts such 'radical edges' as civil unions, equalizing the age of consent, reform of drug laws and large infrastructure reforms.
Interesting to see this being done on a more "normal" amount of tabs. That depends from user to user but IMO a ~50 tab for a power user.

Also it's hard to write good documentation and lots of hackers probably won't have the necessary skill set. However documentation is important and the more you work at it the better and easier it gets.
Nah, it's just the conversion of the video signal to digital packets and back again that's not allowed...because. Perfectly rational!
It makes me a bit suspicious that a Canary build of Chrome is used. I understand that when a new feature is highlighted in a nightly build of Firefox, it's right to show it off - but why not do so against the latest version of Chrome - or even a Dev build? At least those two have been tested first ;)
As an outsider, I think RubyonRails.org is doing a pretty good job.

The install instructions are pretty good, links to documentation and books are good, the screencasts are kept up to date and are IMHO awesome, the blog is active.

What else could you want? I mean, yeah, the Rails Guides could use some more effort as I found them lacking, but it's a lot better than nothing at all (as it used to be).
I used haXe a while back when implementing a concept SCUMM interpreter which worked in Javascript & Flash. It fitted the gap nicely... i could literally use the same code when compiling for flash and javascript.

My only big problem with it was the standalone "neko" target used a bizarre hack which meant integers were limited to 31 bits. This became incredibly problematic when implementing code (e.g. drawing, file loading, interpreting bytecodes) which relied on the assumption that integers were at least 32 bits in size.

There was an official workaround which used an "Int32" class. This effectively meant if you built for "neko" you had to rewrite half your code to use Int32. Bizarrely haXe had no in-built abstraction for transparently handling 32bit integer types in this case.
Notch defends his previous statement calling Euclideon a scam
I stumbled about articles in big German media about this, however nothing on Hacker News and other "non-institutional" sources about hacking! How comes? Is it some propaganda using the media to create a new enemy and prepare a new cyber war? Are there any details what exploits have been used to achieve this?

I would like to know more about it from hacker fellows.

How would you implement a new control structure that way? I think it won't be possible unless you write a parser for the whole language.
Take clojures "or" for example, it's just a macro. The language has only very few primitives [1] and that's the language, everything else is built out of that.

user=> (macroexpand '(or true false))

(let* [or__3470__auto__ true] (if or__3470__auto__ or__3470__auto__ (clojure.core/or false)))

Also, I don't think that lisp "syntax" is unreadable, on the contrary.

Performance is the side-effect, not the cause. The cause is the fact that chrome uses separate processes both for security, and so if one tab crashes, you don't lose them all.

The fact that it uses more memory is a design tradeoff (although with shared text pages it's not as bad as one might think). The real question is whether you would ever have that many tabs open, and how much memory do you have on your desktop?
Ask HN: What happens when a country defaults on it's  debt?
With so many countries seemingly in a crisis ― I am curious as to what happens when a country defaults on it's debt? Does it have to sell it's assets such as Govt. owned companies/factories/resources to the creditor?
They both go very much hand-in-hand. Not saying they should be a single entity, but when you are at-least designing a website you should be aware of what "SEO" tricks are good and bad for the site.

SEO is so bad anyway in my opinion - should be more about User Experience and Usability
Isn't tying ones self worth to others opinion a bit dangerous. There's always going to be people who don't like you/think you provide value etc. It's surely not healthy to rely on others for your self esteem, or to define who you are. This is only a small point from the article but I thought it important to question.
This has been what I've experienced for more than just the latest versions. In personal usage the crossover between Chrome and Firefox has always been in the neighborhood of 20-30 tabs. Past that. Chrome has always seemed more sluggish (and less usable, given how tiny the tabs get).
I can't believe we're still coding this stuff by hand in the 21st century.

Free PSN Codes
The Playstation system card is produced to satisfy a very same really want but also ended up with above all more positive aspects. It was foremost meant in painless means to add over the internet funds into your Playstation store plan with no getting a credit card. I thought this was exceedingly simple for teens who also didn't have the credit cards and / or whose father and mother had been unwilling to enter ones own information and facts via the internet.
too much "ron burgundy"
Firefox compartment memory as well. Using a separate process it the easy way, using thread is the hard way. Each has pro and cons I guess. Even Firefox is getting a multiprocess model for testing.

But for example you can't completely isolate a thread if it crashes. But you can forbid it to access other memory areas for security, that's what Firefox does.

Since Firefox 4 each tab has it's own separate garbage collector.
Also, the other checks, like sockets support X amperes, are much more likely to be satisfied accidentally even though they didn't read the contract carefully.
Absolutely not. You should never sign such a 1-sided contract. It can only hurt you.

Besides which, most of those things are covered by the law, anyhow, and the ones that aren't are questionably legal.

IANAL

We should have some way of the public identifying "extraordinary" issues (e.g. online petitions) and then having periodic referendums where the public can vote directly on these topics.

Otherwise, as you point out, there are many topics that will simply be ignored.

I have spent almost 9640 hours programming...

I started programming when I was in school... But I have been involved in professional programming (working in a firm) for 3 years now... I'm between Intermediate and Senior level... And calculating the time I've spent programming in the firm (only) it would be almost equal to 9640 hours!! :D
What I've always hated about that is there is a sense of an immutable judgement going forward if at some point you perform poorly. Surely it's obvious that that idea is merely an approximation and life is somewhat more complex?

Isn't it the case that if past performance is an indicator of future performance then there is no hope of improving anything?

I really think there is quite serious denial of the possibility of bad things happening to people which effects their performance and it not being their fault, often with very serious consequences for them.

I have a friend who had a family crisis occur during his A-levels; the impact on his future prospects was huge and he has had to struggle to stand a chance at getting a decent job. I personally had a family crisis during my degree which several impacted my performance and has destroyed my confidence, something which still impacts me today (though I did manage to get a 2:1 despite it all),
does that mean I cannot perform well in the future?

I understand what you're saying about there being an overall correlation but I really do think you have to be careful about it - on the whole, it may be true, but it's the individual edge cases that matter, and adopting that position as if it was some immutable fact is dangerous.

Great. Kudus for Microsoft for ending the need for bitmanipulation.

What I always wonder is, how do you commonly go ahead, once you build a successful prototype? Say you want to produce something like 10,000 devices. The Arduino or here the Gadgeteer, is a bit expensive for that. Do you have to start from scratch again, with something like a TI MSP?

I "got it" after reading a bulk of SICP and watching some buddy-lectures at http://academicearth.org/courses/the-structure-and-interpret... (I've also started SICM: it's awesome how they use Scheme.[1]) Nevertheless there's still a level I have yet to reach that I hope to achieve with Clojure (which has recently jumped to the top of my list of languages to learn). While Lisp (Scheme in particular, though CL is nice too) is near my heart, my brain still thinks in Python, Python makes me Happy, and that hinders my speed and concentration when I do stuff in Lisp. I liken it to my experience trying to (unsuccessfully) master Dvorak. The layout was easy to memorize so I could touch-type, I could easily see the benefits, and if I ever get spasms in my hands I'm going to force myself to switch over, but dropping from 80-100wpm down to 10-30wpm was too much loss that I didn't let my finger-muscles relearn and so I'm still with QWERTY.

[1] Even though it's trivial I still adore this simple example:

guile> (define D derivative)
guile> (define f (literal-function 'f))
guile> (define f^2 (expt f 2))
guile> (pe ((D f^2) 't))
(* 2 (f t) ((D f) t))

Add in the little things like being able to have boolean-returning-functions ending with '?', Lisp is very free.

This is exactly it.

I know I'm a loudmouth playing with his megaphone here, but my intentions are good and I'm pointing to things that, I believe, people would like to fix, if only they had the spotlight for a bit. If I can help that process without greatly offending anyone, I'll use my megaphone. I gain nothing from pissing people off without reason.

I didn't get in touch with anyone because I don't have the diplomatic skills to negotiate significant changes to the site, and small patches won't fix the systemic problems with the site (How much negotiation would it take even just to have the official blog posts written properly by a third party? And I already do it anyway, on my own site.) I readily admit I'm a unilateralist who tries to be in charge at most opportunities. This makes me a reasonable entrepreneur, but definitely not the ideal candidate to work in a team to update a community site :-)

Thanks for reminding me of the localized versions. I was aware of their presence but had/have little idea of what they're doing. I can't say I support the idea of an EU-like 20 way translation for every change but that's just my opinion, and I have the utmost respect for local teams trying their best to maintain the site in their own language.
Fios isn't that much of a crap shoot. And it's available in much of lower Manhattan.

I also know for a fact that many unassuming buildings have gigabit ethernet drops that connect directly or semi-directly to 60 Hudson or 111 8th Ave. Probably wouldn't be able to get access without some serious contacts, though.

Most of the co-working spaces I've worked out of have horribly inept people in charge of their network allocation. They use older WiFi routers that have trouble with packet collisions. They provision a 768k DSL line to serve 20 coworking spots.

As recently as two weeks ago, about 16 people overloaded the internet at a coworking space I was visiting. Someone else (not affiliated with the space; the space employee didn't know how to do this) mentioned that they'd initiated a dhcp reset and a couple minutes later everything was back. When I asked him how he knew the router password, he said: "Oh.. they were just using the factory defaults." TBH, I wouldn't want to conduct business over a wifi network whose router was using the default admin password.
I know an anecdote isn't data, but here we go:
I often have >100 tabs open. I also sometimes have to restart my mac, and reopen those tabs. While Chrome then struggles for a few minutes, it doesn't take half an hour, like this article suggests, to open 100+ tabs.
And I did switch to Chrome from Firefox, as it seems to handle a lot of open tabs a lot better.
I don't think legalised is the same thing as decriminalised.

This headline is misleading.

As far as I can tell, this is in fact a draft of a bill which would decriminalise marijuana.

It has not been passed, and even if it eventually is passed (likely in a changed form), it will not make possession and sale legal.
Yeah, the orbital elevators are multipurpose (i.e., to provide a more convenient launching point for spacecraft), but one of their primary goals is to provide electricity. And thus they are closely guarded by the 3 main power blocs (the Union, AEU, and Jinkakuren). Without energy, they are nothing, as can be seen from the countries that aren't a part of one of them and thus live in great poverty.
IMHO no, but I dare say that'll be the minority opinion. People don't like being reminded that they're replaceable.
LLVM is designed to be able to do this.
A few off the top of my head: Square (payments), Tumblr (blogging), Blip.tv (web series destination & distribution platform - disclosure, I work here), Admeld (remnant ad inventory yield optimization for high volume sites), Doubleclick (bought by GOOG a couple years ago), Indaba (music remix platform), a range of creative services (rga and mrm and the like eat souls, though).

There's a lot more here than finance, if you know where to look.
My take is that you should just ignore their request; you're obviously required to return equipment and confidential items when leaving any employ, so you don't need to sign a contract for that - it's dumb for them to ask. The other requests are stupid and pointless - so don't get into it with them.

HR departments are almost always useless SOBs; hell, if they were any good they would figured out how to stop you from leaving in the first place...
There's one noticeable difference for me: I can use it, living outside the US.

Swedish Man Attempts To Build Nuclear Reactor In His Kitchen
Rewrite without deep understanding is bad. alexeiz claimed that the original implementation was bad, but still tried to work on it and decided to rewrite it, in the end, to something he considers clean, and as such, a good work base. The next guy did not even try to work with it, even though alexeiz seemed to have clear ideas on how to implement it on his system (which is, two years later, quite a good indicator of the sanity of the thing). You did not read that carefully, did you ?
Why Google? Why not Apple?

The ultimate cross platform language for me will be one that runs on Android, iOS, Windows, MacOSX and Linux without any change in code. From the article it doesn't look like haxe is trying to do that. But it will be great to have such a language.

P.S. I think Javascript, HTML and CSS is a good combination but not what most people want.
Http://knowita.webs.com/
The 'grid' element is very neat. Basically, it's <table>s, but in CSS, which is where they should be.

Also interesting is that Adobe is taking a front-and-centre role in the new CSS. Forward thinking of them to see the writing on the wall.
Likewise. I typically keep open a large number of tabs, opening a pile of links at once and then going through them during the working day. At any one time, I tend to have a hundred-odd tabs open.

Although to be fair, firefox isn't too happy with that workflow, either - but I blame that partially on flash and javascript.
Cross Application Scripting vulnerability in Android browser
Nope, because you have to understand in depth the existing work in order to rewrite it properly. Then only good rewrite is when you understand the existing stuff enough to see what is wrong with it. You can't rewrite something if you don't know what it does.
If you don't understand it, how do you know what to write?

>Compact, terse, expressive

Does 'Compact' mean that you originally did:

if( foo ) while( foo ){ do something }

all on one line and the boss split them up into multiple lines?

I ask because I worked a job where statements were combined on single lines for ease or reading and it was a nightmare.
> Simple example are many famous artists. They used to be considered quacks, people who are a waste of canvas, but ended up being very influental and quite an important part of our culture.

Performance and public perception are not the same thing. One is much more steady and less susceptible to wild and capricious swings than the other.

Most people have a fairly stable level of performance over time, except when dramatic or destructive events or behaviour interfere (such as drug abuse, stock market crashes, etc.) The millions of people who are stably employed and have been for years are clear evidence of this. If past performance was not an indicator of future performance, then work experience, resumes, and criminal histories are all meaningless.

Past performance is evidence for the consistency of present behaviour.
Experience and learning are programming your brain to predict the future. To maximize your chance of success by action.
Correlation with the past depends on how unpredictable inputs may influence the computation of your future actions.
This has been the main reason why I have not totally committed to Chrome. While I do not usually have 100 tabs open there are times when I do have 30 - 40 open. In Firefox the browser slows down but not horribly so. In Chrome the browser is still usable but it is noticeably slower than Firefox.

I love everything else about Chrome and while I realize that the degraded tab performance is a trade off, it still bugs me enough to not do a full and complete switch. That is why when I am casually browsing the web I will use Firefox. But when I am using a web app or working, I will use Chrome.
I think he wants more than examples. Your examples may be exceptions to the rule. Do you have any numbers?
Are all venues as professional as you appear to be?
I agree with what I think your unstated point is (namely this is basically raytracing). I think the detail here is that this is essentially a sorting/data-organisational solution rather than a geometrically calculated solution. Ray tracing generally takes into account more than one atom (often at complex geometric angles to the directly visible surface) to create a pixel. This claims not to (but to look really good I would have thought it will eventually have to).

So yes. This is a kind of raytracing but I think that the implementation is radically different to the commonly used raytracing implementaions.
