TkCVS is a cross-platform, Tcl/Tk-based GUI for the CVS and Subversion configuration management systems. It displays the status of the files in the current working directory, and provides buttons and menus to execute CVS, Subversion, or RCS commands on the selected files. The Log Browser displays a branch diagram of the revision history. The Module Browser extends CVS with facilities for a user-friendly listing of modules in the repository. TkDiff is included for browsing and merging your changes.
Tux Paint is a simple and entertaining drawing program geared towards young children. It has a simple interface, sound effects, and a cartoon character (Tux, the Linux penguin). Along with drawing brush strokes, lines and shapes, you can also enter text and place "rubber stamp" (or "sticker") images on the picture. Tux Paint is extensible, and could be useful in an educational environment (such as a grammar, elementary, or grade school). It's portable across numerous platforms, and runs well even on slower systems like the Pentium 133MHz.

GNU VPE creates a virtual ethernet by creating host-to-host tunnels between multiple endpoints. Unlike other virtual private "network" solutions which merely create a single tunnel, it creates a real network with multiple endpoints. It is designed to be conceptually simple and straightforward to setup (assuming prior IP routing knowledge) without sacrificing flexibility. It is designed to sit on the gateway machines of company branches to connect them, but it can also be used to tunnel into a VPN with a variety of protocols (RAW IP, ICMP, UDP, TCP, HTTPS-Proxy, DNS).
The VideoLAN Server (VLS) can stream MPEG-1, MPEG-2, and MPEG-4 files, DVDs, digital satellite channels, digital terrestial television channels, and live videos on a network in unicast or multicast. A VideoLAN Client (VLC) or a set top box can receive the stream, decode, and display it.
libelf lets you read, modify or create ELF files in an architecture-independent way. The library takes care of size and endian issues. For example, you can process a file for SPARC processors on an Intel-based system. This library is a clean-room rewrite of the System V Release 4 library, and is supposed to be source code compatible with it. It was meant primarily for porting SVR4 applications to other operating systems, but can also be used as the basis for new applications (and as a light-weight alternative to libbfd).
