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.
GtkEditor is a source code editor widget for GTK+. It is currently used, in one version or another, in several GTK+/GNOME applications, including gIDE, VDKBuilder, and GXEdit. The gtkeditor widget sub-classes the gtktext widget, and after initialization, the editor widget can be treated as the usual text widget, and all source-code editing features are taken care of by the widget itself. The behaviour of the editor is decided by dynamic libraries loaded during initialization of the widget. These libraries can be hand-coded or (in the future) created using tools supplied with GtkEditor.
