The aim of the PicoForge project (previously known as PicoLibre) is to provide a set of high level libre software applications that are well integrated in order to provide a collaborative "forge". It makes it easy to deploy a collaborative work platform for developing software or hosting other collaborative activities. Having started (as PicoLibre) in an educational context, PicoForge is now a quite generic platform, comparable (but sometimes less advanced) to other *-Forge software platforms. It groups several high-level applications like phpGroupware, Sympa, TWiki, Subversion, and CVS.
AbulÉdu is a Ubuntu-based distribution for primary schools. It is currently in French but most of the tools can be translated. An AbulÉdu server can handle Mac, Windows (samba), GNU/Linux and X terminal (with LTSP) clients. The server acts as a central gateway for Web, mail, and printing, and facilitates the management of classes, pupils, and teachers. Everybody can publish Web pages on an intranet using Apache and all administration tasks are performed using a browser. The result is that a teacher who is not a computer specialist can install and manage a school network.

Platform Independent Petri Net Editor (PIPE) creates and analyses Petri Nets quickly, efficiently, and effectively. A key design feature is the modular approach adopted for analysis, enabling new modules to be written easily and powerfully, using built-in data layer methods for standard calculations. Six analysis modules are provided, including Invariant Analysis, State-Space Analysis (deadlock, etc.), and Simulation Analysis and Classification. PIPE adheres to the XML Petri net standard (PNML). The file format for saving and loading Petri Nets is extensible through the use of XSLT, the default being PNML.

It also allows any data to be added to the packet. Checksums can be calculated automatically, but if you wish to send out wrong checksums, that is supported too.
Gpredict is a real time satellite tracking and orbit prediction program. Besides the general orbital data for satellites, gpredict can also calculate the footprint, visibility, doppler shift, signal loss, and signal delay for each satellite relative to one or more ground stations. The calculated data can be viewed in tables, on maps, or on polar graphs.
