Cdarts is a low level implementation of a computer darts player. It can be used as an opponent against a human in the game, or it can be used as a simulator for fun. It currently supports only two different game types (301 and 501), but can be extended to support more games. It supports three different levels: beginner, hobbyist, and professional. Each level tries to simulate a human at that level as well as possible.

Fido is a multi-threaded file watcher which searches files in real time for user-defined patterns. When it locates a match, it runs a user-defined program. It is useful for monitoring log files for issues and responding to them. It was designed to recognize log file rotation and start monitoring from the beginning of the new file.
GNU GLOBAL source code tag system is a source code tagging system which works the same way across diverse environments (Emacs, vi, less, bash, Web browser, etc.). It can locate objects in source files and move there easily. It is useful for hacking a large project containing many subdirectories, many #ifdefs, and many main() functions. It is similar to ctags or etags, but is independent of any editor.
GNU libmicrohttpd is a small C library for embedding HTTP server functionality into other applications. It is reentrant, fast, supports HTTP 1.1, and permits listening on multiple ports. The API is simple and still powerful enough to allow programmers to use the entire HTTP feature set. SSL/TLS support is available as an option.
