TikZ/PGF

TikZ is a graphics system for TeX and friends. It’s very powerful, and somewhat similar to PSTricks. I highly recommend TikZ (and its lower-level engine, PGF) for all your graphics needs when writing LaTeX documents. Here are some examples of things I’ve made with TikZ:

• A document describing stability behavior of linear differential equation systems near the origin. It’s basically copied out of Zill and Cullen, but my version is more complete and more colorful. Here’s the source file so you can see how I did it.
• The Borromean rings. The source is here.

KAIST Sage server

I maintain the KAIST Sage server(s). If you are interested in an account on the Memorial Day server, please email me. Otherwise, anyone can use the Groundhog Day server. (Read about the difference between the two servers.

SageTeX

I’m the main author of the SageTeX package, which allows you to easily pull the results of Sage computations and plots into your LaTeX document. Try it today. If you’re really curious, you can follow SageTeX development at bitbucket.
