Conway's game of life isn't a very realistic use case, a large bit-array with lots of sequential reads/writes. It's always going to be a CPU-bound task, no matter what optimization it gets
More interesting and realistic are the graphical demos, which show off Canvas. The ones which draw something in Canvas and then do nothing more are probably the most realistic real-world-like demos, and they shouldn't cripple anything.
This is an example, and it's an impressively large grid running at decent speeds.
Bram Cohen (bittorrent guy) had a JavaScript game of life on his page at one point, which used tables instead of Canvas, and it was much, much slower on a much, much smaller grid. (I can't find a link for comparison now though)
JS engines aren't currently designed for it, but this is what Canvas (and a lot of HTML5) is all about..
If you prefer think of this as Processing on Canvas, rather than Processing on JavaScript, because Canvas is the enabling technology here.
And I don't know where you get off calling it a "polished turd". (Makes me want to poke around your homepage-vertisement, and see if you have a right to make those judgements)
The Java requirement was always a pain to deal with before, and this "polished turd" removes that and makes visualizations much more portable and easier to play around with.
Also the moving visualizations have always been CPU intensive, that's the nature of what they are; they're supposed to be easy to create visualizations of data, it's not a video game. It was like this on Java too.
Note that the static practical visualizations, which take dynamic data, draw the visualization and then end, need much less CPU than dynamic ones like you might see in a flashy demo.
This is a very good thing, and a very welcome surprise; Processing really does offer something that's pretty unique, and I look forward to seeing more of it. Kudos Resig
It's not clear from the article that they're referring only to persistent connections which remain open but which don't have much activity. The one they analyze is Windows Live Messenger.
They talk about 30% savings in these applications, but also give 59bn kWh as the figure for total power usage for all data centers, the majority of which probably wouldn't benefit from tweaks suited to persistent connections.
You're very unlikely to have to pay a settlement. The cost of paying a settlement is (Chance of being sued)*(Average cost of settlement), if that is less than the cost of the game it's a sound "gamble" to download the game instead of paying.
This is just looking at the "it will cost you" argument, I'm not making any comment on the ethics.
There are also some disadvantages, but the only one that matters is this: It's way more expensive.
If you're upper-middle-class and don't want to feel guilty about global warming then your own solar panel may be a fine power source (and a worthwhile thing to do, nothing to sneeze at), but because it's so expensive it won't come close to being a complete solution.
Power generation is always something that is the most efficient at large scales, and efficient use of efficiently generated power, as the article suggests, is even better of course.
For a cost-efficient, carbon-efficient, scalable, green power source nuclear seems to be the clearest choice
Signatories to the NPT are allowed to enrich Uranium as part of a civilian program. That's right, the question that the IAEA are asking is "had Iran already nullified the treaty by starting their enrichment program in secret?"
The Iranians say "We had bought some cylinders but hadn't started any enrichment yet; we were going to inform you about our program but then it was discovered first"
The IAEA says "Well we checked the buildings and found traces of isotopes from the enrichment process"
The Iranians say "We bought the cylinders from the Indian guy who sold the bomb to Pakistan; the cylinders came with the traces of radiation, that wasn't us"
The Indians, who have the nuclear salesman under house arrest, are reluctant to cooperate in setting up interviews between him and the IAEA, because the nuclear salesman (I forget his name) still has a lot of local support for bringing the technology to India.
The room where the radiation was found was locked up and filled with storage materials, in what may have been an attempt by the Iranians to have that building looked over. The Iranians initially said they developed the centrifuge tech themselves, but eventually backed down on this when the IAEA pointed out the blatantly obvious similarities between the design which the nuclear salesman stole (and the fact that these things take a lot of R&D).
So there's a lot of deception coming from the Iranians on this. They aren't as innocent as you make out, but aren't as clearly headed towards nuking Israel as some media outlets make them out to be either. There are sound economic reasons why Iran would want to pursue nuclear power, but if they only intended to go for civilian nuclear power they certainly approached the problem via needlessly shady and secretive means.
Mahmoud's national image of sticking a middle finger up at the West and putting Iran on the world stage is also probably at play in this affair. Some Iranians joke that if the US wasn't opposed Mahmoud would drop enrichment.
Wow, what is it about Ruby and bitterness/euphoria? In one ear I'm hearing how stupid I am for using PHP and that I could write all the code I've ever written in one line of RoR, in the other ear I'm hearing disillusioned RoR users who are on the brink of suicide over some grievance (and are offering to pay to rent a boxing ring in which to fight me, wow).
Is this a house of cards collapsing under its own hype or.. or what? (I can't help but feel some schadenfreude after the smug "RoR vs PHP/Perl/etc" videos and attitude coming from the ever obnoxious evangelists)

I always found the lesson Spiderman teaches a little weird; if you get bitten by a spider and start stumbling around and seeing everything blurred don't tell a soul, pretend like nothing happened, and go up to your room to sleep.
Agreed, but this issue is pretty much over since someone came up with a plugin for Pidgin that makes the text-area bigger, so the people who would want to use the fork can simply use the plugin.
This fork was a threat by someone who wanted their feature, and won't go anywhere.
I use Pidgin and the static text-box always annoyed me (it has for all IM clients), and the new dynamic one seems like a fine solution. I just don't get why people don't like it..
I also agree that allowing every little thing to be configured is always a bad idea.
I like the feature; before the text-box would be too large or too small, now the space grows as you type. Having a way to customize every little thing is also a waste of space, chances are some user decided he didn't like it and didn't give himself a chance to get used to it.
I just wish they sorted out the crashes on Windows; it's the only choice if you don't like the ads on Live Messenger, but it's really unstable.
I don't know anyone that still watches TV like people used to in the 90s. I haven't rtfa'd yet, but if he's saying that those hours will be put to good use now that we're not watching sitcoms I'm not so hopeful; it's not like you can't waste time on the net, that's all a lot of people (most?) use it for.
Somewhere in a parallel universe people in/. are berating Take Two for trying to turn GTA4 into something new and parting with the tried and tested formula everyone liked the first 3 times.
You have to feel bad for Take Two though; a leak after all the hype and so much care, and all the kids that would have camped out to get it first but now know they're seeing it last because they don't know how to pirate games. That'd be a bummer.
And their model was ALWAYS to sell multiple computers to the same people, through planned obsolescence in 2 years. My 3 year old Dell Inspiron 2200 is still running just as well as when I first bought it, after 3 years of more or less constant use.
Support needed to make a house call once to replace the mobo, and I upgraded with some extra 3rd party RAM, but it's still here and feels as solid as when it was new.
For comparison if I had bought an Apple notebook at the same time I'd be on a G4 iBook at the moment, and probably wouldn't be any more reluctant to update than I am on this machine.
Also I think the GP was saying Apple should look at Dell as an example of what it shouldn't do, so there's no need to reply with the annoying caps-lock emphasis
They always start with the "lowest of the low" precisely because they know no one will object to it. But they NEVER stop there. The next step is "Well, since you gave us information on these really bad guys, you can't object to giving us info on these *sorta* bad guys" which snowballs to the point where the government eventually just has its own monitoring room at your facility to watch *everyone*. Are you saying Google shouldn't do everything it can to wipe this evil from our planet? Pedophile!! Burn the witch!
That's right! First they'll take laser pointers from stupid vandals, then they'll take away our right to free speech, then they'll enslave us and treat us like beasts of burden!

At least I think I'm in Liberty City.. Damn these graphics are good.

Also Shuttleworth paid a lot to get into space, this could just as easily be a philanthropy/brand exposure thing as a real plan to make big profits.
I'm pretty sure more people have heard of Canonical and Shuttleworth now than before he released a Linux distro.
It seems you are confusing the end of support with the end of retail and big brand OEM availibility.
People from Northern Europe don't have much facial hair, but a lot of good coders come from there
