I can't believe my brother does this stuff...

Look at this link for a story about DEF CON, a hacking convention that is attended by professional hackers. It's not a "black hat" hacker convention (i.e., it's not supposed to be for malicious hackers as far as I know) but is attended by computer people who know a lot about hacking. My brother is a computer network security specialist and is attending it this year (as he did the year before). It's amazing and scary how much can be done with technology, and how easy it is to manipulate it. Anyway, not only does my brother attend these things, he's actually won a competition in hacking at one of them. Remind me not to piss him off ;o)
