Submission + - Securing a PC when others have physical access?

An anonymous reader writes: I will be going to college next year and I am concerned about room-mates and other random people having physical access to my computer and viewing/copying my data or putting remote access trojans on it while I am away. I am running Windows XP for software development purposes (and lets be honest, games :-)) and I know that running Windows is a problem but at this point I don't think it can be avoided. I will of course have anti-virus and firewall software but what is the next step? Thank you for reading!

Submission + - Quantum Computer to launch next week

judgecorp writes: "D-Wave Systems of British Columbia is all set to demonstrate a quantum computer. Simple devices have been built in the lab before, and this is still a prototype, but it is a commercial project which aims to get quantum devices into computer rooms, solving tricky problems — and cracking all our codes. Most quantum computers have to be isolated from the outside world (look at them and they stop working). This one is an "adiabatic" quantum computer — which means (in theory, says D-Wave) it can live with thermal noise and give results without having to be isolated. There's a description of it here — and pretty pictures too."
