How long will it take to guess your password?

I came across Bruce Schneier’s article on choosing secure passwords some time ago but just reread it again. I find the description of the efforts that AccessData’s PRTK goes through to guess a password fascinating. Once of the things they teach in security classes is that brute force attacks will always work; the only protection is in the amount of time it will take to succeed. Throw a little intelligence into the guessing and that amount of time can get very short!
