- Ruby/Pcap extension library
- Libnet documentation
- Search for RFCs
Linux clock timings
These show some measurements I have take on the Linux 2.4 kernel clock using gettimeofday(). This returns results with microsecond precision, so I wanted to make sure that this precision was significant. These graphs show that both the millisecond and microsecond parts give fairly uniform results.

A mathematical theory of communication
I've uploaded this famous paper by C.E. Shannon to http://berlin.ccc.de/~cc/shannon-a_mathematical_theory_of_communication.pdf.
You may download it, if you're interested.
