Here's a guide to the programs I've written and put on GitHub. I've excluded repositories that I don't think will be generally useful, such as task code for my research and forks with trivial changes.
My favorite programming language is Perl, but I use R for data analysis and Python for many miscellaneous purposes. I only release software under free licenses, usually the GPL.
- Daylight: Software for doing open-notebook science in Org-mode. I use it for all sorts of documents, including much of this website.
- Citematic: Scrapes and formats citations to journal articles and books. The formatting code is leveraged by Daylight.
- mturk: A command-line interface to Mechanical Turk (distributed as part of boto; see
- Tversky: A Perl module for running psychology experiments on the Web, especially on Mechanical Turk.
- SchizoidPy: A Python module that wraps PsychoPy. The design is somewhat similar to Tversky, but SchizoidPy is for running experiments on a laboratory computer whereas Tversky runs on a web server.
- Clock-Calc: A calculator for working with times of day.
- Oatmeal: A window manager–agnostic workspace switcher with textual previews.
- mt_repl: A Lua REPL for Minetest.
- Polaris: A game about navigation.
