This sounds like a good idea, but can someone with some knowledge in thermal dynamics shed some light into how the effectiveness of these micro pumps? I mean, come on, can those thin layers of liquid weighing less than a few grams actually cool a 20W device? If so, how fast must the pump be running?
I've seen research done on speeding up XML queries with Xilinx FPGA. An opteron 8xx costs about $2000 a piece, so if one of those little sucker can give you at least 3x the performance of an opteron doing SQL query, I say we have a good contender in database applications!
China's Linux policy is part of their strategic growth plan. A nationally funded company develops a flavor of Linux that's very suitable for Chinese gov't use. Microsoft is an American Company, and there's no reason not to believe that they will never help the American government to spy on Chinese government. Linus provides a level-plane playing field for the Chinese government to have control over their own software. Given that Chinese state controlled companies and governments are the largest buyer of legal software, a 27% increase is very reasonable.
I doubt that you will see MS sales increase by that much, though. MS has been trying for year to crack China's market, but they are not successful. The main reason is that MS generate most of the revenue from OEM-bundled OS sales, and most CHinese people still buy white-box PC and get pirated OS. Even with brand-name PC's you can get them with Linux pre-installed, and go home and wipe it clean with a pirated Windows.
Thanks for elaborating my point. What you said precisely explains my point: branch instructions are not slow in nature, but misprediction of branches carries big penalties when you have deep pipelines and slow instruction decoding.
Floating point ops are still slow. They are just faster compared to 10 years ago. An integer op still takes much less time than a floating point op. Thanks to OOOE, the speed of floating point ops can sometimes be masked away from users.
Mod the parent up! Anyone who has been educated in computer architecture would agree with the parent and know that grandparent knows nothing about it. Thank you for posting, parent, I was going to post a very similar comment but you beat me to it.
Just one addition, branch instrucctions don't hold up processors, memory load and floating point instructions do. The problem with the branch instructions is that the branch decision may come too late, and the penalty depends on the depth of the pipeline.
'Paul Ryan, Done Right's chief executive officer, says the missive wasn't sent to him or to his executives -- it landed in a general corporate email inbox,'
I didn't RTFA, but this makes me wonder...did the email happen to be of an Nigerian origin?
Besides- what the hell could we make here to sell to India that China can't make for 1/100th the labor cost?
Everything that is not labor-intensive: airplines (commercial and military), cars, steel-forging technologies, supercomputers, nuclear power plants, advance medical imaging equipments, latest CPUs, to name a few.
China is willing to trade 800 million t-shirts with USA to buy one Boeing 747. Who do you think benefits more from this trade?
For refilling, if there's a will, there will be a way to refill the cartridges (like the HP ink cartridges). The 3lbs weight is a problem to me. I have a Dell 700M with a removable bay, but the laptop itself is only 4 pounds. There's a reason why people stay away from desktop-replacments. On the other hand, I can imagine a battery-renting business at the airport or converntion centers. You won't have to carry it or buy it, just rent it for 5 bucks to wait for your much-delayed flight. (Now a even better excuse for airlines delays!)
I'm guessing it would simiar to lighter/light fluids. You will be allowed to carry up to 1 cartridge with you, but if you need more, you'll have to buy it at destination.
In theory, this will also make them run much faster than is possible today (especially in Xen's case).
These are your original words, and I am saying you are wrong that it will improve Xen's performance. It won't. It will only make xen easier to install and more compatible. It will, however, allow VMware to run faster. I'm not against Xen. In fact I like Xen for its performance. I just don't want your comments to mislead people.
The grandparent is right. These CPU's equipped with Vanderpool or Pacifica are likely to be the new dual-core CPU's. You are also wrong that the virtualization technology is in Xen's favor. It is not. Rather, it's designed to help VMware, whose performance is lower than Xen because the way hardware devices are virtualized in VMware.
I doubt that the naval listening devices can be used at all. These devices are made to capture sounds generated at 300-400m depth (maximum diving depth of most subs). The OBS are used at 3500-4000m depth on the ocean floor.
I was invoking the original meaning of "calculus," not differential and integral. Wikipedia has the following definition:
The word "calculus" stems from the nascent development of mathematics: the early Greeks used pebbles arranged in patterns to learn arithmetic and geometry, and the Latin word for "pebble" is "calculus", a diminutive of calx (genitive calcis) meaning "limestone".
It is true. Back when I was in elementary school in China (1980s), the 4th grade math was exclusively about abacus calculus. The teacher would hit students with a long abacus if she/he caught a mistake in your numbering.
In fact, up till highschool you are not allowed to use any form of calculator; it's considered cheating. All calculation regarding trigonometry and logrithmics are to look up from tables. I am not kidding. I came out that education system and am very proud when I can do the calcuations without a calculator!
DI was nice when 196Kbps streams were available for free, and it was sad in 2003 to see them pulling the plug on free high bitrate streams. I still love di, but only listen to it when http://bluefm.net/ is down.

You took this wrong, mate. The author is a genius and he's giving you a preview of how annoying the Vista UAC is going to be through a web simulation!
Why not take the step a bit further by opensourcing the entire chip design? I bet that will attract a lot of attentions

Well...good thing /. won't let you mod your own comments, even for modding down...

You mean like a /kernel_traffic/.? I bet ReiserFSv4 will get -5 Flame...
Actually, China is one the frontend of adopting IPv6. On the other hand, USA is behind, since the cost of upgrading the entire infrastructure is huge.
China has already implemented this internet, and the url in the OP is hosted on it! That's why I'm getting access denied!
