Welcome to the home of Subsentient. My noteworthy open source projects:

Volition, my ever-expanding pet project RAT, used for administrating many machines at once. Allows loading multithreaded (yes, multithreaded) Lua scripts capable of utilizing libffi.

The Epoch Init System, init system for Linux, designed for user control, unintrusiveness, and efficiency.

Bricktick, Arkanoid/Breakout/brick attack implementation for ncurses written in ANSI C.

WZBlue, GTK+ lobby monitor for Warzone 2100. Written in C, runs on Linux, Unix, Windows, etc.

Warzone 2100, a multiplatform FOSS RTS. I play a LOT of this, like at least once a day, and I'm a code contributor.
