RPM Delta Compression Virtual Update Repository is an experiment to explore the possibility of significantly reducing the bandwidth required to apply updates to a Fedora installation. This software includes a server which provides a virtual update repository to clients such as yum, up2date, or other update tools. It also includes a utility to create and maintain a RPM delta repository. The server will attempt to generate the update RPM from a small delta file applied to a locally stored RPM from the original distribution.
Gravit is a gravity simulator. It uses Newtonian physics using the Barnes-Hut N-body algorithm. Although the main goal of Gravit is to be as accurate as possible, it also creates beautiful looking gravity patterns. It records the history of each particle so that it can animate and display a path of its travels. At any stage you can rotate your view in 3D and zoom in and out. Gravit uses OpenGL, Lua, SDL, SDL_ttf, and SDL_image.
batsh programs perform part of the job in each run. Their exit code is arranged such that qmail-local (and other supervisors) will consider most of the time that batsh exits a temporary failure, and will try again shortly. As such, batsh programs can be restarted at any point without necessarily re-running earlier jobs in the list.
