trend is a general-purpose, efficient trend graph for "live" data. Data is read in ASCII format from a file or continuously from a FIFO, and is played in real-time into a multi-pass trend (much like a CRT oscilloscope or a strip chart). trend can be used as a rapid analysis tool for progressive or time-based data series together with trivial scripting.
ThinLinc is a fast and versatile remote desktop solution. It is based on open source software such as TigerVNC, SSH, and PulseAudio. The ThinLinc server software can be used to publish Linux/Unix desktops and applications to thin clients. The system also supports Windows Remote Desktop Services and VirtualBox. ThinLinc supports redirection of sound, serial ports, disk drives, local printers, and Smart Card readers. Clients are available for a wide variety of platforms. When used with the VirtualGL software, ThinLinc can deliver high performance graphics with OpenGL applications in a thin client environment.
ioquake3 (or ioq3 for short) builds upon id Software's Quake 3 source code release. It cleans it up, fixes bugs, and adds features. Its goal is to be the Quake 3 distribution upon which people base their games and projects. Its design goals include optimizing the engine for playing Quake 3: Arena, Team Arena, and all popular mods. This distribution of the engine has been ported to many new platforms. While it doesn't have PunkBuster (and never will), it does provide more security for servers and clients by way of various bugfixes which aren't in id's client.
pyFormex is a tool for generating, manipulating, and transforming large geometrical models of 3D structures by sequences of mathematical transformations. Thanks to a powerful (Python based) scripting language, it is very well suited for the automated design of spatial frame structures. It provides a wide range of operations on surface meshes, like STL type triangulated surfaces. There are provisions to import medical scan images. pyFormex can also be used as a pre- and post-processor for Finite Element analysis programs. Finally, it might be used just for creating some nice graphics.
HantekDSO is USB oscilloscope software for Hantek/Voltcraft/Darkwire/Protek/Acetech/etc. DSO-2090/2150/2250/5200A/etc. oscilloscopes. It is based on the libusb and Qt/OpenGL libraries. The project includes a firmware extraction utility and udev rules file for loading firmware under Linux/Unix.
