This is already happening (accidentally). Scientists believe that global warming would be much worse right now if it wasn't for the large ammount of light which gets reflected by airplane contrails and particulate matter which we have introduced into the atmosphere.
[snip]
It's possible that as we remove contaminants from our existing emissions, it could actually make the situation worse by accelerating the rate at which global warming takes place...
It's worse than that. Global dimming causes its own set of weather changes. There is evidence that the Ethiopian Famine of the 1970's and 1980's was the result of changes in the monsoon patterns over the Sahel region of sub-Saharan Africa, causing drought and crop failure.
If scientists seriously think that they can use global dimming to neutralize global warming, then we're setting ourselves up for disaster. Maybe not the exact same disaster that would result from global warming alone, but disaster nonetheless.
Perhaps the W3C standard should require that this block of code appear on the home pages of all W3C-compliant websites:
<script language="Javascript" type="text/javascript"> <!-- if ( navigator.appName == "Microsoft Internet Explorer") {
document.write("<p>Your web browser does not comply with current W3C standards. For the best viewing experience, <a href=\"http://www.mozilla.com\">get Mozilla Firefox</a> or any other standards-compliant web browser.</p>") } --> </script>
That would depend to a great extent on where you live. I live in a part of the northern San Fransisco Bay Area that's too sparsely populated for it to be profitable for a grocery store to stay open 24 hours.
Getting back on topic, if someone comes up with an online grocery store where I can get the same level of fresh produce as I can find at my local farmer's market, then I'll be interested.
Many Universities require you to own a PC these days. WHen I went to school 5 years ago, the percentage of people who didn't own their own PC or laptop was vanishingly small- under 10%. The computer labs were only used for special software (say a CAD program), alternative OSes (Unix), and people who wanted to check their email between classes.
Hopefully with Apple's transition to the Intel chip, this requirement will become irrelevant. In fact, I saw an article in BusinessWeek in which the author (can't his name right now) is now recommending the Intel-based Macintoshes to all students entering college, since it can do what 99% of students need out of the box, and the remaining 1% could run Windows alongside MacOS X using either Boot Camp or the just-released Parallels Workstation.
In my case, I own a MacBook Pro and two PC's, but both PC's run Linux, and the MacBook Pro only runs MacOS X. I don't use Windows at all, except when forced to in a computer lab. Then again, I'm a computer science student, so running Linux at home isn't quite to unusual (although not running Windows at all is unusual).
Why not encrypt the disk and put the key on a ROM chip that has a small explosive embedded in it? I would think that ROM chips can be made so small now that they should be easy to obliterate using small explosives that wouldn't put the rest of the system at risk.
Unless, of course, you're worried about the encryption scheme being broken in the near term.

I took a biology class with a professor who had been considering banning laptops from his classes, as he was worried about students playing games instead of paying attention to the lecture. Ultimately, he decided not to ban laptops because I was able to use my laptop on more than a few occasions to look up information relevant to the discussion. A few examples I remember off the top of my head:
* What foods other than fish contain omega-3 fatty acids? (walnuts, flax, and several others listed in the "Omega-3 fatty acids" article on Wikipedia) * What is the root of the word "parthenogenesis"? (from Greek, "parthenos" = virgin, "genesis" = birth) * Is rain expected on the day of our next field trip?
Furthermore, I find that I can take notes more quickly when typing on a keyboard than when writing with a pencil, so the notes I get tend to be more thorough, and I don't have to look down for as long when I'm taking notes. That said, perhaps this is not true for everyone. Maybe for other people the temptation of switching from a word processor to a game is too great, or the bright, shiny display distracts them from what the professor says and does. I don't know enough students who use laptops in-class to make any kind of generalization.
Bottom line: laptop computers can be misused in a classroom environment (one could play "World of Warcraft" on a laptop during a lecture), but the same is true for almost any other tool (one could just as easily play "Pac-Man" on a graphing calculator during a lecture). A tool should not be banned simply because it could be misused.

Why not submerge the board in palm kernel oil? It's liquid at room temperature, and because it's a saturated fat, it won't go rancid nearly as fast as vegetable oil. If you're still worried about it going rancid, try building an airtight computer case; as long as there is no oxygen in contact with the oil, the oil will probably outlast the computer.
And for those of you who read the labels on processed foods and wondered why so many contain palm kernel oil, it's the fact that it's saturated (and therefore has an very long shelf life) that leads so many commercial food processors to use it in places where someone cooking at home would prefer an unsaturated oil.
I once heard a comment from an employee for a certain well-known special effects company in the northern San Francisco bay area that he'd be thrilled to be able to use water-cooled rackmount servers in their render farm. As it stands now with their hundreds (literally!) of high-density servers, all of which are air-cooled, the amount of air conditioning needed to keep them cool is probably high enough to justify the risk of the occasional server failure due to a leak in the water-cooling (a single server in a render farm is NOT mission-critical).
When LinuxWorld came to San Francisco, I mentioned this to a few of the vendors who were showing off loud racks of 1U servers. In every case where they didn't just rattle off the well-known dangers of water-cooling, it almost seemed as if the idea of water-cooling a 1U rack had never crossed their minds.
However, I don't work for any of these companies, so there could be a reason for the seeming non-existence of water-cooled racks that I don't know about.
They all are very similar (hot water, flour, salt, cream of tartar, oil, food coloring) but differ slightly in the proportions of each ingredient. And since the Wikipedia article states that "real" Play-Doh uses a petroleum distillate, I doubt any of these (or any other recipe you'll find on Google) is the authentic recipe.
If nothing else, this means that one could save quite a bit of cash when trying to fool a fingerprint scanner...
