Resume

This site is mostly a collection of projects I’ve worked on in my spare time over the years. Some of my recent and active projects include:

• JWM
  A window manager for X11 written in C. This is perhaps the oldest project I still maintain (started in 2003).

• ScalaCad
  Constructive solid geometry in Scala for creating 3D models to be printed.

• Maze Generators
  Maze generator implementations in lots of programming languages.

• The Q2 Computer
  A single-board discrete transistor computer.

Some other things I’ve worked on in the past that may be of interest:

• TI-83/83+ Assembly Programs
  A collection of TI-83 and TI-83+ programs I wrote in z80 assembly language while in high school, including the Ion shell and several games.

• The Q1 Computer
  A computer built almost entirely out of about 3000 discrete bipolar transistors.

• Altair 680 on an FPGA
  A complete implementation of the Altair 680 computer system in Verilog capable of running a version of BASIC from 1978.

• ScalaStan
  An open-source project I created while working at CiBO Technologies ScalaStan is a wrapper and DSL in Scala for the Stan probabilistic programming language.

My GitHub has some more projects.
