Not really. One of the reasons that chips are getting faster and faster is that they are getting smaller and smaller.
I'm probably using incorrect terms here, but you should be able to figure out what I mean: The longer a given trace is (distance from one transistor to another), the longer amount of time it will take to signal a state change (0-->1 or 1-->0). Now expand this single trace idea to all the traces on the chip, and you get a significant propogation delay.
This will most definately slow the chip down, and may not help the heat problem either. This assumes that you're using the same number and type of transistors... those are still going to be generating heat. Granted, it will be spread out further as you suggested, but thermal conduction will do that anyway.
If you don't care about bleeding edge performance, then just underclock existing chips.
Pardon my ignorance, but after poking around on a xvid site a bit (meaning that I read the FAQ), I learned that xvid is a video-only codec. What if sound is needed as well?
Is there anything that has both audio and video capabilities that uses the xvid codec for the video part?
I can't find mention of the underlying codebase for the "Access like" functionality. Does anyone know what DB code they are using?
From the article:
One noteworthy addition to this upcoming 2.0 OO.o release is the HSQL Embedded database engine a fast Java-based embedded database engine that once surprised everyone by beating IBM's Cloudscape (now also open sourced) and even C++ databases. Also included is a user friendly database application dubbed "OpenOffice Base" which allows you to effortlessly create both databases, queries and reports using helpful "wizards".
Or maybe it just took a while for NASA to figure out what spin to put on the story. You don't think they tell us about everything that goes wrong as soon as it happens, do you?
Speaking from indirect experience (two coworkers were laid off Sept 30), things aren't all that great in the Indianapolis Area. It's been 6 or 7 weeks, and they still haven't even gotten any (quality) interviews yet.
Cryptography - A Very Short Introduction is an good book to introduce concepts of crypto. It's not a detailed manual about how any specific ciphers work, just an introduction to concepts.
these lists will simply contain the hashes along with the addresses
According to the article, there is also a timestamp associated with each hashcash stamp. So a CD full of hashes along with addresses as you propose will only be of value for a limited time.
Of course, the list could be processed *again* and you would have a fresh list, also of value only for a limited time. This process can be repeated ad nauseam, but new lists require new work.
The article did not mention a timeframe in which a stamp would be valid (other than not in the future, and not too far in the past). One could infer that the length of time in the past could be shortened, thus shortening the lifespan of a given spam list, and consequently increasing the amount of work to keep it up to date. The number of bits could also be increased to make creating a spam list more expensive.
Also, each stamp is only good once. When a stamp is spent, it's rendered useless.
In summary, you make a good point that spammers share information. However, I think that the expense of creating these stamps on a continual basis is not negligible. The real question becomes whether the expense of creating the stamps exceeds the revenue generated by the spam.
Some acoustic physicist please explain to me: Why wouldn't earphones work better underwater? AFAIK sound is propagated through compression waves, so it should work fine underwater as the density is greater. Am I missing something?
IANAAP (acoustic physicist), but it's not really a matter of the sound transmission properties of water, more a matter of the physical structure of the earphones.
If they were designed to operate by oscillating against air, then trying to operate by oscillating against water (which is more dense, as you stated) won't work... at least not as well.
Yeah, in a perfect world nobody gains access to your box and jacks your files. But here in Real Life(tm), crap happens. Why not limit your exposure in case it does? CD burners and blanks are cheap.

You just turn them over. Really. Sort of like a left- or right-handed coffee mug... just rotate 180 degrees.

Shouldn't that be 1997-2005?
I think that "All your base..." guy called dibs.
Oh yeah, there's a Potter/Weasley/Snape version too:

I'm sure that Veggie Tales would do fine as well. Plus this seems to be their specialty, anyway... animated veggies, that is.
Not to not-pick, but it is in Beta. I would expect your ire were it directed at a "complete" and released product.

The only thing that they have in common with Swatch is geography.

Exactly. You don't have to outrun the bear. You just have to outrun the slowest camper.
Don't worry, though. The printer will be free, but the toner will cost you!

The developers only planned on 640k of cache. Bill said that's all they would need.

I originally meant to attach my reply to the McBride comment. After realizing what I had done, I thought that it was even funnier here.
Isn't he the president of the hair club for men? Sure looks like it!

What kind of fools do you take us for? Everyone knows the bikini scene is in ep VI.
You know, I didn't realize how big a nerd I was, until I just typed that.
You leave tax records on your hard drive? Ballsy.
