comment Using a weak password on a truecrypt volume
@drjimbob : I agree with you, if you know about security. For any person that who knows about security and how to deal with it, the more security you have, the better, and 0,5 is more than 0. I just got tired of finding people using a login password in the Windows and thinking that the computer was secure, just to show them that with a linux boot cd I could copy any file I wanted. User's fault? Maybe, but no message warns that it just provides a very weak protection. And, as I said, in general we deal with users, and users... are users.

Just please remember that "delete" an archive isn't enough, you should overwrite it...

comment Would it make sense to use Bcrypt and PBKDF2 together?
Protect from a broken hash: if all are working ok, brute-force would spend x times in the first hash and y time in the second hash, with a total of x+y. If any is fully compromised, the attacker will spend the total of 1+y or x+1, and the order didn't matter.

comment What is the most reliable way to transfer emails without specific recipient support?
Don't want to prevent discussion, ideas, etc., but in other words you're asking "We know email wasn't built to be that secure, but it's still used. We know there's a lot of research about it, but all solutions need some change in the current model. Is there a magic solution to solve all those weakness in it's design without any change?"

comment Are there sensors/devices to be used for reading magnetic bits of hard disk
You could try to use a SEM microscope. for example, if you really want to know how each bit looks like.
