BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
columbus is useful when you use your machine in different networks (it's great for laptop users). It uses ARP pings to look for known MAC-IP address correspondences, and can do this even when no IP address has been assigned yet. columbus can be hooked up to your network script. It can also be hooked up to your apmd and be told to re-check the network each time the computer wakes up. It also has a modified version of one of Donald Becker's link check tools to check your network when your network cable is plugged back in and if necessary, execute all synchronisation steps.
KBACKUP is intended for handling of backups no matter whether they reside on disk or tape or even in files. As most other backup programs available today are either confusing the user with lots of long command line options, or user friendly but not powerful at all, the aim behind writing KBACKUP was to provide a user friendly yet powerful backup program. It is also intended to be kept compatible to existing and well proven archive formats, so you can restore your archives even if you should not have KBACKUP around anymore.
The MirBSD Korn Shell (mksh) is an actively developed successor of pdksh (the Public Domain Korn Shell), aimed at producing a shell good for interactive use, but with the primary focus on scripting. It is intended to be portable to most *nix-like operating systems as long as they're not too obscure. mksh incorporates improvements from OpenBSD and Debian, as well as bugfixes and enhancements developed for the MirOS, FreeWRT, and MidnightBSD projects and Android. The emacs command line editing mode is UTF-8 capable, and Byte Order Marks are ignored in scripts. The shell supports large files, as well as all pdksh and some csh, AT&T ksh, zsh, and GNU bash features, is compatible with the Bourne shell and POSIX (within limits), has no limit on array sizes, and incorporates some other useful builtins and features. While being already fast and small (without losing functionality), flags to make it even smaller can be given at compile time. An interactive shell reads "~/.mkshrc" on startup.
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.
TVEz is a browser-based system to manage movies, shows, and clips stored on local or remote file systems. It is also a front end to the XINE video player that makes the control of the player possible from the Web browser. It retrieves information about movies, including an image of the cover, from IMDB, and stores that information in a MySQL database. The database entries are fully searchable by director, writers, actors, titles, etc. It includes a rating system for movies by which movies can be sorted such that your most favorite ones appear on top of the list. The Web-based configuration is generic enough so that any kind of show can easily be added to the shows listing. The playlist is fully manageable.
