I suspect this isn't so much about power as it is about temperature. With a dual-core chip, you expect both cores to contribute 50% to the heat load. If one core's throttled back, you can overdrive the other core without the chip overheating.
The other transition, where the chip workload increases & voltage/frequency are limited to keep within a power envelope, is called "throttling" and is much disliked in the user community.
Who cares, when you won't notice the throttling since the throttled core was sitting idle anyway? They're not slowing down the core you're using.
FTS: A new study shows that presence of the US, Asia, and Western European countries on the web is strongly declining.
No it's not, the % of total traffic that goes to these countries is declining. Harrison's page says nothing about the total amount of traffic over the period examined, so it's entirely possible that the absolute amount of traffic to these sites has risen.
Harrison's 'research', or at least the presentation thereof, stinks. He's playing with percentages to make the change seem more dramatic. The numbers on the front page don't add up, either.
Not the error itself, but the fact NASA was able to figure out what happened in such detail, when the spacecraft it happened to is not giving any diagnostic information and cannot be examined directly.
High-end and pro sound 'cards' often have a PCI board that handles the interface to the computer, plus AD/DA converters in a separate, shielded box to keep the analog circuits away from the computer's EM fields.
Oh please. You're making it sound as if Tiger will stop working on 1-May-07 and you'll be without a computer for 4 months. Tiger's still a perfectly serviceable OS. Get some perspective.
They've released 10.1-10.4 on time, and pulled off the Intel transition months ahead of schedule.
And let's be honest, it's not as if Tiger doesn't stack up favorably to Vista, and Apple desperately needs Leopard to convince people to switch.
TFA says they increase the surface area without increasing the dimensions of the panel. But that's not enough. Let's say that the 3D panel has 10 times the surface area of a flat panel, with the same dimensions. It still receives the same 1400 W/sq m as a flat solar panel, so the amount of solar power going into each sq cm of the panel has to drop to 1/10. It seems to me that the 3D panel wouldn't produce any more power than the flat design. So there has to be a second effect at work. Let's see if we can find a better article than the information-starved FA? this article claims that the efficiency is increased due to reflections, i.e. each photon has more than one chance of being caught by a PN junction. Ah.
I wonder if this would work on macro scale, by placing two panels at a 45 degree angle to the sun, and 90 degrees to each other, like this \/. That would double the efficiency of both panels, without the drawback of using nanoscale structures. The panels would have to track the sun for this to work, though.
I had the same question. Google dug up this answer. You won't like it. Summary: we're being saddled with yet another boneheaded 'standard' by penny-pinching, buzzword-driven morons.

I know some people who have glasses with a coating that reacts to the amount of light. Even indoors, those glasses are always slightly tinted (maybe 10%). You probably get used to that, but it seems to me that sometimes that 10% is too much. This electrochromatic coating better be completely transparent.
Oh, and what about failure modes? If the battery dies, will the glasses go dark or transparent?
I first read about this idea several years ago, but haven't been able to find out what happened after those first experiments with a motorbike. Attaching the system to a bus is a stroke of genius.
I don't think so. With these glasses you're just filtering out certain frequencies. What you would need to help colourblind people would be glasses that can frequency-shift incoming information. That is doable, but currently the rigs to do this (IR goggles) are quite bulky, and monochromatic.
The examples offered are no easier to remember than a numerical code, and have the added hassle of having to convert it back to numbers before you enter it. (not owning a Wii, IDK how the code is entered: if it's a 0-9 keypad with the letters also printed on the keys (like a phone) the conversion isn't necessary).
To me, it seems the problem is more fundamental. Why did Nintendo assign random 16-digit numbers instead of allowing users to choose their own 'friend code'? My name (if needed, with a 3-digit number attached to prevent namespace collisions) is much more memorable than any code Nintendo can come up with.
Aren't there yellow glasses for people with bad night vision that reduce glare?
Yup. I've got a pair of those. AFAIK my night vision is okay, but headlight glare annoys me; driving with these glasses is a lot less tiring. I also use them during dusk/dawn and in bad weather: they decrease contrast, making dark areas more visible.
In an age where people understand such development principles like Moore's Law, you would think that people would have a little more imagination when it comes to the future of resource exploration in the next century or so.
Wait, you think that Moore's Law applies to anything besides semiconductor production? Do you know how rare it is to see such a quantum leap in performance, let alone have an industry keep this up for 20-30 years? Uranium isn't going to drop out of the sky on its own accord, it'll have to be mined, and the mining industry is subject to the same economic realities as the rest of the world (with semiconductor production as the sole exception).
Yup, same here. Except I stopped bothering with printers 10 years ago, when I got out of college. With no more papers to hand in in dead tree format, I found I rarely printed anything anymore. If the information is in a computer, I prefer viewing it on screen to printing it. I kept the printer I had then for a few more years, but it just sat gathering dust so I tossed it eventually. Same with another printer I got for free with a second-hand computer. So I haven't had a printer at home for about 5 years now, and good riddance. For the ~5 letters I write in a year, I just use a laser printer at the office.
If you print at two-week intervals, yes. If the interval gets longer, there comes a point where no amount of cleaning fluids will unclog the heads. I've ruined an Epson printer and several HP cartridges by not using them for 4 months. I tried cleaning with increasingly aggressive materials (water, alcohol, paint thinner iirc) without success.

At 750 Mb, it won't be DVD quality, let alone the quality expected when you say 'HD'. It may be 720p, but it'll be compressed all to hell.

Yup. Evidence.
So that's the first OLED. Truly, there's nothing new under the sun.
Pfft. Any material (semiconductor or otherwise) can be made to emit smoke. It's just a matter of applying enough power.

Once they introduce a version that can be added as a coating to regular glasses, that is. It's got to be better than using clip-ons.

this will lead to renewed interest in breeder reactors. Recycling nuclear waste is a good thing.
