1) Disable all plugins and add-ons, and re-enable 1-by-1 until you find the one that leaks.
2) about:memory (will likely show not much as it's almost certainly a plugin/add-on that leaks)
3) Make sure that General->Advanced->Submit performance data is enabled, so if it's really a leak in Firefox, it can be tracked down.

If you still see 1.6G memory usage even with all add-ons and plugins disabled, be sure to report a bug. (I'm assuming you don't have hundreds of tabs open or anything which would otherwise explain that)
Scottish wind turbine explodes in storm
I used water cooling. With 5970 it do not adds too much to price, but helps keep cards cool in tight environment. Specifically, I had microATX case with two 5970 at 850 Mhz (it could handle more, but just wanted to feel safer). GPUs were staying at 55-65 C. I bet you can do better if you route separate water tubes to each card (which I did not because of tight environment and being lazy :))

Before adding water cooling - it would lock after 30 minutes of mining at standard 725 Mhz.

This system worked very well for ~4 months (and then I sold it to guy from Alaska, since it became too hot in Texas :))

I agree with what you said. We should not be mad that he hasn't done it, we should be mad when a presidential candidate makes the ridiculous claim that he could do anything in the first place.

I love candidates like Ron Paul, but even he is dishonest when he says he could "drain the swamp" and cut $1 trillion from the budget. No President has that kind of power.

I Know What You Downloaded on BitTorrent…
Blergh, this isn't a GET if you're doing this.

GET is for retrieving a resource, which is like a fixed representation of data. In your example, you're trying to do a function call, an RPC, and badly mapping it to HTTP semantics.

That's what POST is for.

You could maybe do something like this:

GET /orders/432544 HTTP/1.1
Host: www.example.com
Accept: application/json;bsaunder=1.0;calories

And, of course, technically, you CAN pass a body with your GET. The spec does not disallow bodies on GETs. Roy Fielding, however, would disapprove:

More importantly, the project descriptions, like bundler's Gemfile, is a local decryption of the dependencies. And this allows you to have project scope libs, instead of system scope libs.
This is the same individualistic fallacy that comes up over and over again. Yes, individual actions matter for your own personal integrity, but focusing on those as a solution to what is essentially a systemic problem ignores root causes.

Society is a system that's just waiting to be hacked, if you're willing to start seeing it that way.

I think both interpretations can be defended. Though if you're playing with the Accept: header it's important to correctly set Vary: as well.

> But in my experience, requiring Accept manipulation outside of .json versus .xml makes your service less usable by clients, which often don't expose anything besides the url.

Browsers have that limitation (and numerous others), but if a programmatic HTTP library does not expose this, you need to throw it out. The Accept header is not part of the "immutable" headers of XHR either.
I can't find anything named Microsoft AMP. However, it sounds like you're talking about DirectCompute, the compute API for DirectX.

AMD will support DirectCompute because its the native API on Windows, the same way they continue to support Direct3D. This doesn't mean that Direct3D is more viable of an API than OpenGL, but it means its popular on one platform.

Silicon Valley’s Latest Debate Is Portfolio vs Persistence
I don't buy the first point. Maybe my friends don't share everything sad, but some do share hardships and from experience, Facebook friends can sometimes become and additional support group. For example, when our baby was having cardiac surgery, my wife and I decided to share some of our experience and the positive is that you can keep your friends informed and get a lot of moral support when you most need it. It was awesome. Some of that support translated in real life too. It doesn't replace family or close friends that are present in your real life during these times, but it can be a valuable addition.

Same thing for the third point. Wether with Twitter or Facebook, we've had many real life impromptu meet ups we would never had before these tools because of status updates.

Social networks are tools. What matters is how you and your friends are using these. Of course, some friends only use these for self promotion or self gratification but you tend to notice and behaviors and filter out those updates that never lead to mean something.

On the other hand, if your life is miserable in the first place, I can see cases where Facebook could make your life more miserable. Again, it all depends on how your use it, your attitude and what you make of it.

Firefox existed before Google funded it through the deal. If anyone, Netscape made Firefox. Heck, they actually made it, with no ones help and they actually created one of the first successful, fully open browser.
They're also the reason you have even Chrome today. Let's not change history too much.

Now that's true Firefox today is sustained by Google's money primarily (but I'm sure it would be fine with Bing's money - its all about money for corporations, and Firefox still has a large user base).

I also doubt they hate Firefox. But Chrome's advertisement budget alone is 20 times higher than what they pay to Firefox. That's quite a bit.

Certainly there are interests in Firefox's demise for Chrome (and for IE). You'll notice IE's marketing study was _exactly_ the same at Chrome's one.

Put IE on top, Chrome behind (it would be make the study looks too fake if they're all put too low and Chrome is the cool kid right now), then Firefox last, and no one cares for Opera, Safari, etc.

Why? Because it has nothing to do with technical details. It has everything to do with advertisement (or FUD, like we called it back in the days.)
> GET is for retrieving a resource, which is like a fixed representation of data. In your example, you're trying to do a function call, an RPC, and badly mapping it to HTTP semantics.

I don't really agree with that: he wants to retrieve a subset of a resource, that's a resource in itself. Using a more standard selection language, his query could be rewritten:

GET /orders/432544?path=%2Ftoppings%2Fcalories HTTP/1.1

and would be perfectly sensible.
One S2050 has four M2050s, not two (I inferred this assumption from your 6.5 multiple).

I'd like more information on the CPUs and CPU/GPU bus of this FASTRA II. CPUs are really gaining back a lot of their performance relative to GPUs - an M2090 is only about 5-10x faster than the newer Intel Xeons in a properly multithreaded program that pays attention to the NUMA nodes. This is efficient enough that for large simulations which do not fit on one GPU, running portions of the simulation on CPU easily overcomes the CPU/GPU communication overhead in terms of performance.

The whole concept reminds me a bit of the "bagel guy" in Freakonomics. If I remember correctly, he had an ~85% payment rate when it was strictly on the honour system.

I'd be curious to know their payment rate. On one hand you'd expect it to go up since they actually have the name and e-mail address of the buyer (the bagel guy had nothing). But on the other hand, the whole impersonal nature of the internet might increase fraud. Could go either way.

(for those who haven't read Freakonomics, the "bagel" guy would drop off a box of bagels in an office and pick up the remaining bagels and the proceeds at the end of the day)

I'm not totally sure this is really written for the HN audience, but since its self-submitted I'm going to speak my mind.

Everyone with any chops in silicon valley already knows this. It's established conventional wisdom at this point. Yes, there are still a lot of people who need to hear it (I sit next to them on airplanes sometimes), but around here this is preaching to the choir in the most fundamental sense. Furthermore, debating the nuance of such a proclamation is masturbatory. Yes reality is nuanced, you can always find a counter-example, but frankly an intellectual understanding of the relative importance of "ideas" (whatever that really means in a knowledge economy) is probably one of the most useless forms of wisdom you can aspire to as an entrepreneur.

Yes, but the Avalanche effect does not mean it is not invertible. It is possible to design a one way hash function with remarkable avalanche (50% of flipped bits on average after 1 bit change in input) effect but that is easily invertible.

The simplest would be an hash function that outputs an N-bit hash where M bits are a pseudo-random sequence of bits (depending on the input, let's say SHA1(input)) that are used to key a stream cipher, and the rest N-M bits are the XOR between the stream cipher output and part of the input of the hash function.

Perfect Avalanche effect, but the function is invertible.

I haven't used Android (aside from on my Kindle Fire) enough to form an educated position on it. The Kindle Fire's UI is both (a) gratuitously animated and (b) laggy, but I tend to assume that if the UI were more utilitarian it would be less laggy. If this is not the case, then Android is simply broken.

It still seems to me that there are different routes to implementing UI elements in Android and some work better than others. E.g. some aspects of the Kindle Fire's UI are consistently inconsistent as it were, while others seem to be perfectly solid. If I were in charge of Android I would focus on getting the basics right and forget about the eye candy. It's not that Android can _never_ compete with iOS (or whatever) in the eye candy department, but that you should crawl before you walk etc.

My impression of Linux from my various encounters with it (including trying to live with Ubuntu as my primary OS for a couple of months) is that it fails both as a utilitarian OS and an aesthetically pleasing one. (And yes, I'm sure there are plenty of suggestions for alternate UI systems from KDE to flux box that will somehow not have whatever issue I find.)

If you don't think an app you start writing today will still be being used in 10 years time, you're being short-sighted in my opinion. That kind of attitude is the reason so many companies are still stuck on IE6 (which came out just over ten years ago) due to poorly written intranet apps.

The official GNU grep used to be absurdly slow at UTF-8. Linux distributors very quickly noticed this and fixed it when they switched to UTF-8 by default. But GNU grep maintenance was essentially dormant for years and these patches were only integrated in 2010.

For an old, unpatched GNU grep a 2000x slowdown is quite believable.

Who has been saying this "for so long"?

That original position was to not care about it for your production code - keep on doing your thing, but keep an eye on 3.x enough that you know what's going on and can make the switch when ready.

Definitely true. I think, unfortunately, that it seems like the hacker mentality also lends itself more to cynicism, and the end result is that the hacker mentality lends itself more to a bit of fatalism when it comes to the government. That, combined with the (less pronounced, perhaps) tendency of the hacker mentality to dovetail with introversion, makes it harder for the hacker community to get involved in that sense.

That sounds cynical, of course. I do think we can get better :) And I think SOPA for one was a great example of the community going “hang on just a second here…”

As far as I know, grep uses Boyer-Moore for string matching when possible. Giving a variable char size encoding such as UTF8, plain Boyer-Moore isn't possible, but it is the asymptotically faster algorithm known.

Hence even perfect versions of grep will slower by arbitrarily large factors, depending on the input.

So while there may be problems, expecting no difference or no significant difference between encodings is not correct either
