Great episodes to start the new year off.

Ahhhhhhhhhhhhh. I installed Ophcrack on my 8GB Cruzer and lost it at school this morning, luckily the Rainbow tables weren't installed but if they find out about Ophcrack and get it running and hack all of the school's passwords... And I'm a memory stick down

Otherwise a great episode; Ophcrack is a great program, is there a way to still use it and deny access to the files; a password or something.

Granted this may not be as glamorous as using Ophcrack, and maybe I'm missing something from having not used it myself. But if all you're after is a Windows password, you have physical access to the machine, and the system drive is not encrypted, why not just use this boot disk and be done with it. This is my preferred tool to help people who have forgotten their Windows passwords or reset the passwords on machines I buy at local auctions. It usually takes longer to boot the disk than it does to actually zero out the passwords.

Probably the best episode aired on revision3 yet! Great job guys. Keep it up.

Interesting article about a gpu cluster.
