It seems that Donald Knuth had his bank accounts attacked not once but three times using his checking account number off of checks he sent out for bounties for flaws in his books and software, and is thus ending a practice of nearly 40 years. Rather sad. I mark this as another milestone in the slow destruction of the idea that it is okay for an account number to be the secret used to effect payment in a transaction system. http://www-cs-faculty.stanford.edu/~knuth/news08.html Perry -- Perry E.
