Compilers

I'm the primary author of the LLVM Compiler Infrastructure, an ambitious project to build a system of reusable compiler components that let you build all kinds of tools: compilers, debuggers, JIT systems, optimizers, static analysis systems, etc. In its current form, LLVM is most often used as an aggressive optimizer for C and C++, which can produce machine code for X86, ARM, PowerPC, Sparc, Alpha, and several other targets. LLVM is being extended and enhanced in a tremendous number of directions to support new optimizations, new targets, new domains, and to get new features. We hope to make it the future of open source compiler development. If you're interested, please join us!

Travel

I enjoy traveling, and have seen most of the lower 49 states. Beyond that, I've had the opportunity to do some sightseeing outside the US. Here are some pictures from my more picturesque trips:

Operating Systems
  1. Operating Systems Resource Center - Huge collection of information, useful if you're writing an operating system or device driver.

Graphics
  1. Raytracer Page - Graphical fun, including photon mapping, procedural texturing, many primitives, etc...
  2. The GRAS Robotics Simulator - A 3d graphical robotics program writen in Java.
  3. GraphPro Articles - Bare metal graphics programming tutorials for DOS.
  4. Spiffy Pilot - A project from high-school. (OLD)
Other technical stuff
  1. Projects page - An obsolete list of projects I've worked on.
  2. MagicStats Home - A free software, automated web statistics application.
  3. Java Programming - Random toys, including a robotics simulator.
  4. A DFA driven Lexer, written in Haskell.
  5. Miscellaneous documentation mirrored here.
