The data at Top500 shows a linear increase (on a semi-log plot) for the entire time from 1993 to today. Every seven years, the performance increases by a factor of 100, but Moore's Law predicts an increase of 2^(7/1.5) = 25, meaning that the supercomputer market is besting Moore's Law by a factor of 4.
And if you read the attached DOJ report you find that it calls the statistic that guns prevented 1.5 million crimes "absurd" and questions the validity of that number (page 9).
Faraday cages block EM waves by having holes that are smaller than the wavelength of the wave. (This is why your microwave can have little holes that allow you to see in, but keep the radiation from leaking out.) By packing waves into an even smaller space, they would be able to pass straight through a Faraday cage.
It depends on why they're vegan. If it is to stop animal cruelty, then vat-o-meat should be fine. If it for health reasons, then vat-o-meat will have just as much fat and cholesterol as the real stuff.
I'm continually amazed that the CS majors at my major US accredited university can't program using pointers, object oriented techniques, or parallelism. I think that there is an attitude among the professors that this material is difficult, so it shouldn't be worth a lot of points. As a result, the students don't bother to learn it.
I work in another department and sadly, without formal CS experience, I'm a better programmer than many (if not most) of the CS department's graduates. I don't think, however, that this problem is unique to my school. I've visited other US universities where the situation is very similar.
In fact, I recently took an informal survey of about a dozen CS seniors and found that none (yes, none) of them knew what K&R, the "white book", or the "Art of Computer Programming" were.
This is a perfect example of Slashdot. The top story is about how owning a cat lowers your risk of a heart attack and stroke, with a comment that correlation does not imply causation, and three stories down is a piece about bad science journalism. =-)
Before we claim that the Standard Model is the end all of particle physics, lets see if we can find the Higgs Boson. Afterall, Fermilab has come very, very close, so the LHC should be able to seal the deal.
I had the unique experience to go to Japan two years ago as part of an NSF funded research project. When I got there, I was shocked to find that my 15.4" laptop was the biggest in the room. Out of 30 or so people, about a third had Apples, and the other two-thirds had Windows machines, but they were small.
It wasn't unusual to see the participants carrying their laptops through the halls with the display open, holding it one-handed by a corner, and continuing to type as they went.
While American laptops tend to be "full fat" beasts (see the 17" one at ZaReason.com, or the 21" mammoth at Dell), the Japanese have embraced smaller, more portable laptops (like the Kojinsha).
Of course, the Japanese machines weren't as underpowered as the Eee PC is, but I think the Eee PC is a very good first step in getting Americans to let go of their bigger-is-better attitude when it comes to laptops.
One last comment - my 15.4" laptop is too big to open when I fly coach. The front to back distance is such that it ends up jabbing me in the stomach. My next machine will definitely be 13" or less, no matter what.
I did notice the Kaffeine icon on the desktop in one of the shots. Forgetting the keyboard for a moment, the whole thing looks like a big brick. And the "virtual display" is nothing new... I had a Pentium 166 laptop running Windows 95 that did the same thing.
Technically speaking, the poster/article should say 'human-provided' energy. After, if switchgrass took in X amount of energy and produced 540% of X in output, that would break the laws of thermodynamics.
Also of consideration is what is the energy yield per acre? Of course, corn at 24% would be a total loser ($1 of energy provides $.24 of energy), but even at 540%, switch grass might not be the most economical method based on land used. Consider if you supply an acre of switch grass with 1 watt of power and it produces 5.4 watts - that's definitely not worth it.
I happen to be in an area where I have two and only two options for high speed Internet: Comcast and ATT.
Right now, I have Comcast and am paying through the nose for it. I'm thinking of switching to ATT, which will cut my monthly bill in about half.
But price aside, I'm curious what the Slashdot crowd thinks of the choice between ATT and Comcast simply from a moral ground. Which company, in your view, is "better"? And I don't mean which company makes it easier to pirate materials, but which company behaves more ethically?
The inverse square law only applies to an isotropic source - a light that's being emitted in every direction (like a candle). This is why lasers stay bright at a distance.
All that matters here is light output divided by the square inches of the screen. Assuming that this screen has a 4:3 aspect ratio and produces a 50" diagonal image, that means it produces 1200 sq in of image. This gives 10 lumens / 1200 sq in =.008 lumen / sq in.
I have no idea though if that's a lot or a little.
I'm a long haul trucker and I have to say these things are a life-saver. Instead of nodding off at the wheel like I used to, now I can watch a handful of movies as I drive between Chicago and LA.
I read somewhere that the anticipated price of the boxes will be around $50. If that's true, then $10 out of pocket is not bad/unreasonable. However, looking at BestBuy.com right now, the only dtv converter they have retails for $180. There's no way I'm spending $180-$40=$140x2=$280 to continue watching TV on my two sets. The whole point of over-the-air transmissions is to save a little money.
Has anyone heard if these converters will require another remote? Or will they remap the digital channels onto the analog ones so that you can use your TV's analog tuner to change channels? Another reason I don't have cable or satellite is that I don't like having to use two remotes to watch TV. One for volume and one to change channels is a real pain to me. (And yes, I have heard about universal remote controls.)
Did you notice how they listed that it doesn't run Mac or Windows software as a drawback? Vista doesn't run Mac, Linux, and some XP software, but you never see that listed in the reviews. To take a $200 computer and review it compared to one costing twice as much (or more), it should be obvious which one is superior.
Isn't it amazing that 25 years after the release of the CD, we're excited to finally have a way to buy DRM free, lossless, digital music? If this happens, we'll be back inline with 1982 technology.
The big thing on Wikipedia right now is marking up articles for not quoting their sources. But for a theorem, the proof is the source. If you don't include the proof, then no one has any way of knowing the validity of your claim.
Also, slight changes in wording can drastically change the content of a theorem. By supplying a proof, it becomes very clear if the theorem has been stated correctly or not.

Well, then mine excess H20 so that you have enough oxygen. It's not that big of a deal to expel waste H2 into space.

The trade-off of course is having to submit to a serial number inspection upon every loading of the game.

Oh no! Socialized television! We're a bunch of dirty red commies!
Where's McCarthy when you need him... =)
I've been using Tyan Thunders for the last five years. I've been very happy and had very few problems with them.
I hadn't seen the specs for this device until now, but it sports a 800x480 screen - the same as the EeePc.
