they implemented caps using packeteer to limit the dorms p2p to 20mbps download and 2mbps upload. They did this in reaction to the insane amount of usage, almost 40% of the campus bandwidth.
An interesting paper was written recently by a group in the CS Dept on content delivery systems. They monitored the campus network's border routers for 9 days. The result - Kazaa consumed almost 14TB outgoing and only 2TB incoming. This is in comparison to 3TB outgoing for web and 1.5TB incoming.
What surprised me the most was that more p2p content is leaving the dorms than coming in.
I for one would not trust this system with my credit card or atm card. The system can be quite easily fooled with some super-glue, a pcb board, and gelatin.
Bruce Schneier wrote an article about the process and which also has link to the presention given by the Japanese professor who came up with and tested the process.
The Simultaneous Multithreading technology was coined as hyperthreading by Intel. It was originally developed at the University of Washington by one of my professors and some of her colleagues. Check out the SMT page for a brief overview of how it works and links to many technical papers describing it in more detail.
There was an adapted short story based on "Unlocking the Sky" that was in MIT's tech review magazine this month. Here is the part I found most interesting (and related to ProfessorPuke's post above):
"For his part, Glenn Curtiss did receive a number of patents over his lifetime. But he always permitted further use of the principles underlying his inventions - a strategy that enormously benefited the emerging industry. Unlike the Wrights, Curtiss believed that invertions and products had to succeed or fail in the marketplace on their own merit. The goal, he said, ought to be simply to keep building better airplanes than anyone else."
It is too bad inventors these days (and the corporations that employ them) don't take this kind of view.
..."remind me again why i would have any good reason to run LinuxPPC?"
uhh.. how about speed. I ran MacOSX on my powerbook 400 with 192 mb ram and it was SLOW. Granted it is a beta version but it will never compare to wm, afterstep, blackbox or any other fast window manager.
Not everyone has the $$$ for an SMP box with gobs of ram.

Here is an article from Scientific American giving a good overview of the basics of quantum computing.
It's a bit dated (from 1998) but the principles are the same.
