Y2K UNIX style:
Forget the Mayans and their silly 2012 doomsday scenario. The real end of the world will happen because of that most venerable of operating systems: UNIX.
That's because next Friday, UNIX time will read 1234567890. Scary! And, it just so happens that this event will coincide with one of the more superstitious days on our calendar, Friday the 13th. Scarier!
