Gspy retrieves images from a video4linux device and processes these into a daily MPEG movie on the disk drive. Each image is recorded with a time stamp to ensure accurate real-world correlation. Special motion detection algorithms are used to reduce the size of the daily movies by eliminating pictures with similar content as well as the normal compression obtained by the mpeg process. The result is a time lapse video per day with nonlinear time compression using only the images of interest.
Gstring is yet another guitar tuning application. It requires a soundcard, a microphone, the FFTW package, and if you want a GUI, the Gtk+ toolkit and a new Gtk+ widget called GtkDatabox. A non- Gui version called "string" is included in version 1.0.0 and dynamically linked binaries (for i386 machines) are included as well.
gsysinfo is a GNOME panel applet, modeled after the "xsysinfo" monitor. It displays system load, CPU usage (broken down by system/user/nice/idle), memory usage (normal/kernel cache/available), and swap space usage. Each of the gauges can be turned on or off, and the colours can be configured as desired.
