All shared files (e.g. Audio or Video files) are directly visible and can be played using your favorite media player. djmount is written in C for the Linux operating system. It is free software, licensed under the terms of the GNU General Public License (GNU GPL).

dvdbackup is a tool to rip video DVDs from the command line. It has the advantages of being small, fast, and easy to use.

The dvdisaster project: dvdisaster provides a margin of safety against data loss on CD and DVD media caused by aging or scratches. * dvdisaster creates error correction data to compensate read errors which are not correctable in the CD/DVD drive. * dvdisaster tries to read as much data as possible from defective media. Afterwards unreadable sectors are recovered using the previously created error correction data. The maximum error correction capacity is user-selectable. * dvdisaster operates at the image level and does not depend on the file system. If you create the error correction data in time and keep it at a safe place, you have a good chance of recovering the medium contents from typical read errors and to transfer your complete data onto a new medium.

CPU is an LDAP user management tool written in C and loosely based on FreeBSD's pw(8). The goal of CPU is to be a suitable replacement of the useradd/usermod/userdel utilities for administrators using an LDAP backend and wishing to have a suite of command line tools for doing the administration.

The cpulimit program throttles back a process's CPU usage. This allows the user to slow down jobs that would otherwise choke the processor. It is also helpful on laptops where we want to avoid generating a lot of heat.
