These pages contain the notes and some other materials for courses I taught for UCSD Extension.

Presence and Telepresence was a one-day seminar on virtual reality I gave in 1992 and 1993. C Programming was a one-quarter course I wrote in 1995 and taught for several quarters after that. I wrote Introduction to Programming in 1995 as an introduction to the C course. For a couple of years I taught both courses, then I taught only Intro until 2002.
