ThoughtPad is a simple multi-document editor for taking and organizing notes quickly. You can edit in the text area. Switching to another file is just one menu action. Save, Save As, Rename, and Delete do pretty much what you'd expect. Options allow customizing the colors and fonts.
fnkdat is a C header and source file that may be statically linked to a binary. It provides a platform independent interface for determining common directory names (e.g. "user directory", "config directory", etc...). It's particularly well suited for games, but by no means limited to that use.
Hot Potato Online is a fast paced arena sport game where players try to explode the opposition using a short-fused potato bomb. The generated environment can be used to bounce, corner, and surprise foes. Up to 4 players can confront each other in detailed customized matches. It's similar to dodgeball with a grenade.
PasswordNotify was written to solve a long-standing need of ActiveDirectory and OpenLDAP administrators. It simply queries your LDAP server once a day and notifies a user when their password is about to expire. It is highly customizable, and runs as either a Unix cron job or a Windows service.
Csound is a powerful and yet easy to use musical synthesis package. Csound was constructed in the tradition of so-called music-N languages, among which the best-known is Music V. It consists of an orchestra- and score-driven executable, written in C for portability. Since Csound is a computational language, it is highly flexible and efficient; complexity is gained only at the expense of computation power. Basically, Csound reads some files and creates the result as a sound file on disk or, on faster machines, in real time through a DAC.
