This Samsung ML-85G printer driver can print at the full resolution of 600x600 dpi, and at the maximum speed (about two times faster than the driver supplied by the manufacturer under Windows). It needs Ghostscript to convert your PostScript files into PBM images, piping the output directly to the driver. The driver runs in user space, but calls iopl(), so it should be set suid root to execute transparently.
Rpm2tar is a utility for converting the contents of a binary RPM package into a gzipped tar archive. Rpm2tar attempts to preserve file ownership, groups, and permissions as they are stored in the RPM package. Rpm2tar handles files only; it does not handle pre- or post-install scripts, triggers, '%config' tags, or any other fancy features of RPM.
rproxy is an extension to HTTP which allows transferring of differences between a web server and client, using an algorithm similar to rsync's. This works particularly well for dynamically-generated sites, where the pages are often similar but not the same on each visit. Transferring just the difference reduces network traffic and therefore loading time.
REXEC is a secure, decentralized remote execution system for running parallel and sequential jobs on a cluster of computers. It provides high availability, scalability, transparent remote execution, dynamic cluster configuration, decoupled node discovery and selection, a well-defined failure and cleanup model, parallel and distributed program support, and strong authentication and encryption.
