The latest Dr. Dobb's issue (May 2002 - Algorithms) has a nice article about "Good Hash Tables & Multiple Hash Functions" written by Michael Mitzenmacher (who also teaches 'Algorithms and Data Structures' at the Extension School -- a very good follow-up course to this course). The April issue also had an article by him about how to extract more randomness from a biased source. Hash functions will be introduced in the April 17 lecture.
