I've found the backlight and hard drive use far more power than the processor, regardless of the mode.
Wow, that isn't at all true with the Pentium-M. My T40 can run anywhere from about 5 hours down to 1:40, just by running a cpu hungry program. I run a daemon which scales the CPU MHz depending on the load, when you crank it up the fan comes on and you can feel the heat blowing out the side and (surprise!) the battery life prediction from 'apm' drops like a rock. Fortunately I can still play a movie while doing some word processing with the CPU stuck down at 600mhz.
The Pentium-M doesn't seem to be able to do much more computation with a given a mount of power than any other CPU; it just does a better job of scaling down power usage when you're not crunching.
As for the HLT instruction, I don't know that there's any OS that doesn't issue it, nor do I know whether it helps at all. You'd think it would be easy to make it so a CPU not doing anything wouldn't use (hardly) any power; apparently that's not true.
Seriously, some of the advocacy groups would rather we not solve the energy problem--or, they'd rather we solve it by means other than finding even a clean, abundant energy source.
Isn't "abundant" a relative term? If we find something cheap and clean, we'll just use more and more until either it's scarce (expensive) or wrecks the environment somehow.
This isn't solar power. Not because the energy didn't ultimately come from the sun, but because that's not what "solar power" means. If it was, then everything including petrolium would be solar power (except non-solar nuclear power, such as from geothermal or a nuke plant). And every power source I know of would be "nuclear power," including solar.
I doesn't give him credibility, just the opposite. It just highlights that what a company says can usually be safely ignored if they have a vested interest. (And yes, that includes RedHat, and no, "Open Source" and "Linux" are not companies).
...closely followed by Apple's AAC implementation and LAME MP3, which improved markably since last year thanks to further tunings of its VBR model done by Gabriel Bouvigne.
You see? The benchmarking has already resulted in better mp3 encoding, which is still compatible with all those devices people own. So even if mp3 can't be dethroned, these tests benefit everybody.
Yes, it makes a PDF of all the pages, but each page is just a picture. There's no way to search for text in the result.
There is no way you're going to solve that problem with one person and a couple hundred dollars.
I know there are Adobe archival systems that store the scanned image, along with whatever text they manage to recognize. You don't expect near 100% OCR accuracy from an old, largely handwritten sheaf of lecture notes and transparencies. But hopefully enough is recognized to be of some use.
How many me-too articles we'll be seeing thanks to Super Size Me (the movie about the guy who ate only at McDonalds for a month with bad results).
I don't see how this evaluation of energy drinks means anything, because he had more than one per sitting. Who's to say which one did what, or how they cross-reacted?

These comparisons of browsers today vs. yesteryear mean nothing, when the Web of today is totally different than it used to be. You can't even make sense of the web with mosaic any more.
Determine the pounds of documentation necessary to specify the set of "web standards" required to comfortably view the Web, now vs. 10 years ago. That includes Javascript, CSS, DHTML, if not flash and Java itself. HTML itself is a mere drop in the bucket!
And with the proliferation of broadband, pages are getting more and more content rich (aka bloated). Sure there were "inline images" back then, but if you were to plot the average number of images per page (or flash apps, or HTTP requests per page, etc) over the past several years, what would you find?
Are programmers really producing bloated and wasteful code? I'd argue the Web itself is more to blame.
People freak out about seti@home, but not about cpu-hogging screensavers (GLPipes, anyone?) or bandwidth-hogging animated doubleclick.net ads. Just an observation.
Look at it this way, do you think you throw away enough food every day to heat your home, take a warm shower, and drive your car to work and back? I sure don't.
I don't deem people in general responsible enough to carry loaded guns.
Cops are "people in general."
Those who trust government and distrust people have a serious problem... they don't realize government is just a bunch of regular people doing jobs - some well, some not so well, just like anywhere else.
I wish reviewers would start including a section on how much power the systems take. I'd like to replace my home server box and would like to minimze power consumption since it runs 24/7. I'd also like to replace my 'desktop' PC and would like to minimize fans because I like to listen to music on it.
The problem is distributing keys. This is an answer - distribute them with DNS.
Unfortunately many ISPs force all outgoing mail to go through them (including mine), which means filtering on the sending MTA is rather crude - e.g. you can either allow or disallow all mail from hotmail.com.
Re:Inflation (more data)

Out of Gas

· Score: 1
Here's another very interesting chart - historic gas prices adjusted for inflation.
What this chart shows is that gas prices are very high, even taking inflation into account! Not the highest they've ever been, but higher than in the "gas crisis" late 70s, higher in fact than every other period except the early 80s.
What's really stupid is saying, "don't worry, inflation-adjusted gas prices have been higher - just look at the early 80s" when you consider the miserable unemployment and staggering inflation of the US economy in the early 80s! Is that what we have to look forward to?
EU GDP: 11.50 trillion Pop: 454,900,000
US GDP: 10.40 trillion Pop: 290,343,000
Sure a trillion more is a lot in absolute terms, but it's only 10%.
Anyways in this case it might be more relavant to define a "software GDP," and for now I think the US would be #1 in that dept.
If the EU does resist software patents, it should be interesting to watch: will monetizing every little idea create more value for US companies and keep them in the lead, or will the increased freedom in the EU lead to products that integrate all the best features, leading to EU dominance? And does Microsoft even care, since they can easily buy any company with patents they want? Stay tuned...
The bikes weigh, what, 80 lbs? A Honda Civic is 2500 lbs, a Hummer H2 is 6400 lbs. Let's not begrudge the Chinese a vehicle that probably gets the equivalent of 100 mpg.
A lot of power for mobile devices these days is used for wireless communications. How much power it takes to broadcast a signal for a given distance, through walls and clouds, etc is a pretty well understood issue and there are not going to be any real breakthroughs. That videoconferencing wristwatch is going to need a powerful, tiny battery (unless maybe we put a relay station every few hundred feet!).
Well, what about heat? What the device does with the extra power isn't the battery's problem. Or if you like you can make a battery with the same old capacity but 1/4 the size, which would be great in itself.
There is no right in the copyright law to make backup copies of motion pictures, so the whole argument that people should have the right to make backup copies of DVDs has no legal support whatsoever.
A couple points:
first, why does it matter whether the right was previously in copyright law? Wouldn't the point of the new law be to do just that?
Second, what is not illegal is legal. It would be nice to have a law explicitly protecting copies for valid purposes, but I would settle for repealing the law that currently makes this a crime.
It's kind of a bizarre setup we have, let me see if I get this straight:
1) Copy music CDs for personal use: legal
2) Copy game CDs for personal use: illegal
2) Copy TV shows for personal use: legal
3) Copy DVDs for personal use: illegal
