I have two pieces of advice for snowboarders. First, I have very wide feet and I have found that Ride makes a boot called the Orion that I've found very comfortable. Second, don't buy Lamar bindings with plastic latches - mine lasted two seasons and then the tabs broke. Right now, I'm trying "Flow" bindings, and I like them so far. They're very fast to pop on and off, but I have had a little bit of trouble setting them too tight.

I work at ATI (a subsidiary of AMD) in the Workstation ISV Engineering group, helping ISVs and customers use OpenGL and workstation graphics GPU features.

My experience includes 3D graphics, both interactive and high-quality offline rendering, and Linux/UNIX-like systems as well as Windows. In particular, I have expertise in using OpenGL in applications and middleware, and in writing tests and benchmarks for OpenGL drivers in Windows and XFree86. My resume in PDF format is available for your review.

Engineering

• I'm the proprietor and system administrator for my community server Plunk.Org. (It's in my basement.)
• A long time ago, a bunch of friends and I ported BSD UNIX to the Mac II. We called it "MacBSD". Our code formed the basis for the mac68k port of NetBSD.

• In my spare time many years ago, I built a tristripping API called ACTC, which is being used by Lawrence Livermore in a visualization system and by Digital Anvil in game authoring tools, among other projects. Before that, I wrote a less flexible tristripping API called Meshifier, used by Ubisoft to create models for their game Ultimate Golf; ACTC fixes several problems in Meshifier and provides a better API.

• Lawrence Kesteloot and I worked for many years on a Z80 homebrew computer that we called the Alice II. We created some web pages documenting our adventures.

Out and About

• I appeared briefly in the movie "Revolution OS" playing Richard Stallman's "Open Software Song" (ugh) with "The Gnu Stallmans". I have an entry on IMDB, the Internet Movie Database .
• Back in college, my friend Lawrence and I competed with each other to write the shortest program that would ray-trace shaded spheres and provide an ASCII art image of the result. He made a web page describing our competition. The programs are very ugly and illustrate some things you may not know can be done in the C programming language.
• I organized and moderated a panel called "When Will Ray-Tracing Replace Rasterization?" at SIGGRAPH 2002 Interactive ray-tracing remains a hobby of mine, and it continues to make inroads on rasterization with the inevitability of the planets moving through the sky.
• I joined Dave Shreiner and our friends in courses at SIGGRAPH 2002, 2003, and 2004 on "Performance OpenGL".
• Neal Tringham fixed my old Meshifier triangle stripping code and used it to create an online optimization tool. Models in Ultimate Golf by Ubi Soft were processed with that tool. (I recommend using my ACTC package, mentioned above.)
• I presented part of and wrote part of the course notes for the SIGGRAPH '97, '98, '99, and '00 full day course called Advanced Graphics Programming Techniques with OpenGL, and also the SIGGRAPH '99 Lighting and Shading Techniques for Interactive Applications course.
