I used to work as the system administrator for the Systems and Networking research group in the computer science department of UCSD.

Now I am a researcher and technical specialist with the Abagyan Lab at UCSD. My main work web site is here and my lab web site is here.

Personal Gentoo Installation Notes
Gentoo is a Do-It-Yourself operating system. I'm a DIY kind of guy and this is how I do Gentoo. This contains some bash optimizations over the normal install procedure. The idea is to segregate interactive time from wait time so you can go to bed during compiles.

Simplified MySQL Reference
Here are my personal notes on MySQL. This covers the basics of getting a database setup and doing things. It is designed to help with infrequent things that are done when a project is started or modified (creating tables, adding a field, etc).

Beginner's Python Tutorial
At first Python seemed kind of werid to me. But I decided to get to know it and wow! I can't believe I ever accomplished anything without it! What's the big deal about Python? Well, you have to use it a bit to find out. To do that, you need to learn a bit about it. If you'd like to do that, then start here.

Regular Expression Tutorial
I am an expert in the use of "regular expressions". I developed this tutorial for my students and anyone interested in taking advantage of the power of regular expressions.

Simplified Tk Reference
Most information about Tk is either too incomplete or too comprehensive (i.e. the man pages). This collection of notes attempts to provide a typical look at what each Tk widget does and how it does it.

Perl CGI Security Notes
I gave a talk a the San Diego Supercomputer Center about Perl CGI security issues. This explains how to write secure CGI programs and insecure things to avoid. Perl CGI security is as easy as choosing good passwords, but like with passwords, you need a bit of knowledge and you need to actually follow through.

Perl Reference Demos
This collection of extremely simple but illustrative Perl programs serves as a reference for fundamental Perl topics. It was compiled from fragments of code that I have developed for actual use and also from purely illustrative examples for Perl lessons I have given. It is a good place for beginners to be reminded how various important mechanisms work in Perl.

Linux Stuff
My answers to Linux questions and some helpful notes that I have created.

Interesting C/C++ Topics
Somehow I can't seem to write a C/C++ program without dredging up some very obscure or bizarre topic. These are notes that explain and provide examples of these topics.

Authentication
My PGP/GPG Public Key.

Engineering Work
Information about manufacturing engineering work I've done.
