UFOClock draws an astronomical clock. From it you can read the time of day, phase of the lunar month, ratio of day to night, time until a solstice or equinox, and time until the end or beginning of twilight. The time of day depends on your location on the surface of the Earth, which you can enter on the command line or in a dotfile in your home directory. Location can be given as latitude/longitude or ZIP code. It is called UFO clock because it sort of looks like crop circles. It is based on Sundial by George Williams. It requires GLUT installed to run and the NOVAS library to build.

xseg (eXtented SErver Grapher) is a server monitoring tool. It can check whether your server's services are alive. Its output is written to an HTML file. xseg can check the services on both local and remote machines. xseg can also run user-defined shell commands and write the stdout of these commands to an output file. This makes xseg very flexible, since you can write your own shell scripts and xseg will run them and capture their output.
