although its a nice novelty to have a solar-backpack, the real good news is that this trend will eventually bring down solar panel prices and make them avaliable to a wider audience. the biggest obstacle today to a solar panel on every roof is cost and installation, for they are already highly efficient (they can capture something like 30% of all energy to that hits a certain surface).

its a community rebuild of Redhat Enterprise 2/3. Many (admittedly mostly non-critical) machines at the lab I work at are being converted to CentOS machines. The rest that need support are being Suse-fied. What really needs to happen is someone to scare redhat by exposing an open source world that can survive without redhat.
The United States, at least since WW2, has never produced enough engineers and scientists to meet its own demand; the best and brightest have traditionally gone on to business or law school. (This is very evident in the immigratation patterns over the past 60 or so years. The US has been tremendously agressive in importing scientists, engineers, medical doctors and other technically skilled persons.) In the mean time, developing countries such as India and South Korea have been investing heavily in the technical fields (out of which IIT was born). Thats why Stanford, Berkeley, MIT, and other top research universities have disproportioniate numbers of 1st and 2nd generation immigrants.
For example I work at an Accelerator Physics Laboratory; among the dozen or so PhD's in my divison, 8 of them are immigrants from less fortunate countries.
there's this intersection near a secluded freeway entrance, controlled by lights. it seems that unless you're car is at a specific spot, the entrance to the freeway doesn't turn green.
We've outsourced US work oversea so much that now, since people are willing to work for such low wages (combined with more advanced forms of telecommuting), we soon may be able to insource work. That would be an interesting trend.
leaving on a 300 watt computer for use as a phone is over kill. there's got to be some sort of stand-alone solution that basically replaces the phone altogether.
there are plenty of tiny implementations of either. if I were you I'd use a higher level parser/lexical analyzer generator than lex/flex/yacc/bison.
also check out the 'Introduction to Compiler Construction With Unix' from prentice hall, sadly out of print, and 'Compilers' by Aho.
Solar panels can capture maybe 30% efficiency (thats very good), and with wind mills and sometimes water wheels, alternative energy can potentially support a household with a running refrigerator, a couple of computers, and all the other modern conviniences, and still have energy to share.
The two main problems:
1) Cost. A full set of solar panels can cost in the tens of thousands. At Berkeley recently, they invented cells that are paper thin (and consequently cheap) but they have yet to hit the market (that I know of). Wind mills aren't cheap either, and neither are the batteries to store all that juice.
2) Complexity: Setting up and maintaining an alternative energy source system is not a trivial matter. Not only does it require some electrical knowledge, but set-up also needs substantial physical labor. Most people are not willing/unable to do so.
in order for these technologies to succeed, it simply needs to get cheaper, simpler, and more importantly there needs to be businesses specifically supporting installation and maintanance.
First off, I seriously doubt many highschools are teaching parallel computing as part of their computer science curriculum. Second, a decent cluster of 8 nodes or so can be had for less than 10k, well within academic research budgets. Third, I never said anything was wrong with it; I'm just saying its not something thats practical.
I'd just like to point out that the point of a cluster is not to link together a bunch of cheap machines to save money; the time and energy required to write paralleled programs far exceed the cost of hardware. Rather, the point is to gather the highest end commodity machines you can afford and attain mainframe-level performance.

do any of us actually have 80 GB of music we would want to listen to? I don't.
- IE4
then BEA, now Google. ???just what we need, more linux distributions :-).
only $565 million? just sneak into his house and scavenge his couch for change that slipped out his pockets.
Why aren't more distros offering DVD isos? it would be so much more tidy, not to mention more torrent-friendly.

those are the folks who don't accept evolution, right?

suing whoever the hell worte outlook. oh wait..
until we can replace all military personnel Microsoft Certified robots, are we going to outsource to india?
"Could this be it?" no, it's not "it". "it" is a mass produced, 2 gram piece of latex that is designed to fit around your woodrow. use it.

is why is Badnarik and Cobb the only two making noise? Kerry and the democratic party leadership should be demanding a recount more than anyone.

Please tell me this isn't a Windows-only service.
Didn't you here what Ashcroft said in his resignation? The threat of terrorism is over! Let the good times roll.

So that one paragraph about how Dick Cheney turns into the Hulk when he gets angry was just childish vandalism?! Hmph!
there are tapes that can also store hundreds of gigabytes. what I'm concerned about is how fast you can get that info off of the disc.

anything that chips away from oracle is good news.
