Interesting article on TCP/IP network security.
Its a bit esoteric, but it reviews how the random sequence numbers are generated for various operating systems and network devices. Lots of them aren't so random, so the underlying OS or device(s) are not so secure, either.

The graphs also show the beauty of mathematics.

All the major news stations suck. I planned to boycott TV today, but a PBS special last night changed my mind. They highlighted how Canadians supported all the stranded air travelers that were grounded for the days following the 9.11.01 attack. PBS is cool.
