U-Hexen is a port of the popular 3D game, Hexen by Raven Software/Id Software, to the Simple Directmedia Layer library. It uses an SDL mixer for sound and music. Some new menus were added for easier configuration. It works on Linux, FreeBSD, OpenBSD, and Windows. On FreeBSD, the game can work on the console without X.
System Configuration Collector collects and classifies most of your Unix/Linux/BSD configuration data in flat files called snapshots. This allows changes in snapshots of consecutive runs to be detected. These changes are added to a logbook, which is helpful for administrators during troubleshooting and for auditors during audits. Snapshots and logbooks are also available in HTML format. All data can be send to an SCC server, where a Web interface provides access to summaries and supports comparing snapshots of different servers and searching of all data. A WMI-based Windows client is also available.
Roap is a text file processor. It scans a text file, extracts regions that match specified patterns, and processes these regions sequentially using specifed executables. Each executable reads the region as stdin, and their combined stdouts are written as the stdout of Roap. Patterns and executables are specified using XML.
McStas is a computer program (written in C) that enables you to model very precisely a neutron instrument described as a series of various components. A source component shoots each neutron randomly (Monte-Carlo), and the particle is then propagated through the different instrument components. These later act on the neutron characteristics (position, speed, direction, spin, etc.). Usually, one installs some detectors along the neutron path to monitor its characteristics and flux.
SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.
