[pchelpers] Re: News:Russians start selling Wi-Fi encryption cracker

Hi John,

Yes, it's been in the news, and I may even have first seen it in one
of your news postings from a couple of years ago. Modern video chips
are powerful general-purpose parallel processors (and I think each
generation jumps an order of magnitude). CPUs can do a few things at
the same time, while GPUs can do hundreds, thousands, or millions (I
don't recall how many) of certain types of operations at the same
time.

Good advice is like good paint- it only works if applied.
