Looks like we've got an ultimate evidence for a recent discussion of what a Slashdotter needs to read before posting a comment - a headline, that is. I'm all for carving this one in a stone as a memorial for future generations of Slashdotters...
That's not a problem, I did set up some public school terminals recently, with every user having their account. The terminals are netbooted with a read-only rootfs (NFSv3), home directories are mounted read-write trough a PPPoE tunnel authenticated with the users's login and password (= only the active users's home directory is mounted), and, the most important thing, the system is equpped with full grsecurity framework, ACLs, TPE (Trusted Path Execution, simply the user is unable to run anything that I didn't allow him to), restricted scripting languages and a few more simple tricks. That, and KDE running with some kiosk options turned on, makes an unbreakable system, at least as long as the users are not Mitnicks - and, in the least likely case of a break-in, even every single exec() is logged off-site, just waiting to print it and hand over to the headmaster (or, had it been a company, the boss). Of course, the system won't even run when there's no connection with the external logging daemon, so unplugging it for a few minutes to hide something won't do.
As a few people said, GPU could be used for some heavy-duty data processing, especially vector and matrix math. And what to use for output? DVI. It's digital. So you just put the data into AGP, make GPU process it and get the result as three-channel data stream (RGB).

...the Talibs put a "No entry" traffic sign on a supply route?

I wonder, did they already ask the Slashdot team to not link them? They're *always* down after being linked here...

Wow, an astonishing piece of news - there's atmosphere on the Moon!
It's very simple and elegant, supports e-mail and Jabber notifications and is a snap to set up. http://flyspray.rocks.cc/

You see, I am *technically* able to run IE on my system, wine does its job pretty well - but M$'s EULA forbids me. What do I do now?
