KNOPPIX is a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI devices, and other peripherals. It can be used as a Linux demo, educational CD, rescue system, etc. It is not necessary to install anything on a hard disk due to on-the-fly decompression.
GNUSTEP Live CD contains a lot of software for GNUstep, a free implementation of the OPENSTEP framework (which is also directly used in Mac OS X as Cocoa). It includes excellent applications for RAD (GORM and ProjectCenter). The CD is available for i486, AMD64, Apple Mac PowerPC, and Sun UltraSPARC computers.
Genmenu can generate menus for Blackbox, Fluxbox, Openbox, Window Maker, and Enlightenment based on the program binaries found installed on a system. The list of programs to search for are contained within the script. Users can, to a limited degree, customize their menus via a set of interactive questions.
wmweather displays your current local weather conditions. After supplying a 4-character METAR station identifier code (most major airports have one), it shows station ID, time of the last update, temperature, dew point, pressure, humidity, and wind speed. The various entries can be forced to display in a variety of different units.
Allin1 is a little dock applet for FluxBox and similar window managers. It monitors CPU load with a moving graph, memory and swap usage with histograms, battery and power status with histogram and icons, ethernet/PPP interfaces with icons and histograms (linear or logaritmic), filesystem space, and Seti@home progress.
The goal of the General Applet Interface Library is to give programmers a simple yet powerful applet interface. This library supports wmapplet/dockapps, GNOME 2 panel applets, and ROX panel applets. The applet programmer doesn't have to care about where the applet will be used, since the library handles that. Over 50% of the code in a dockapp and a GNOME 2 Panel applet does only one thing, setting up the applet window. With GAI, this can be reduced to just a few lines of code.
