Introduction

I'm trying to make this page have to do with everything I do related to the field of computer science. My favorite endeavor is to share as much unclassified information as I can so that others can leapfrog over my achievements and makes some new and innovative advances. I have spent a great deal of time searching for information on particular topics, only to find a dearth of explanation and derivation. Although I'm also not perfect in this regard, yet I believe I may be an improvement. Most of my work to date is graphics and game related, and not exactly complex, however I know that complex programs are typically composed of many simpler components.

Recommendable Books on Programming

The books I suggest are those that I have read a considerable amount from (more than 50 pages) and have enjoyed completely.

Class Handouts

Every once in awhile I have the opportunity to teach. I believe that the ability to convey information to others is just as important as learning it yourself. To this end, I typically try to make detailed and lucid material to help students grasp the concepts and facts I'm supposed to be teaching or helping to teach them. My attempts to this end are given below.

CS61A Handouts - The product of TAing the Structure and Interpretation of Computer Programs course at UC Berkeley for three semesters in row. The book they use is excellent, however it does tend to loose students with its approach of teaching the subject. I tried to give the students an optional resource for learning what we were trying to teach them. (Spring 1998, Summer 1998, Fall 1998)
CS61C Handouts - What I was able to do in one semester of TAing the Computer Architecture & Design course at UC Berkeley. This happened to be a very turbulent semester at Berkeley, and having only had one semester to create handouts, I simply did my best in the time I had available.

Experiences to Share

Whatever experiences of slightly technical nature I care to let people know about. Usually something really bad or superb in nature.

History: Learning to Program - A description of how I learned to program with links to some of my oldest available code.
My general views and thoughts about MUDs. (Old, a 1995 or 1996 product)
Incomplete C Lessons - My first attempt at sharing knowledge on-line.
