CODESH (COllaborative DEvelopment SHell) is an automatic persistent logbook for sessions of personal command line work. It records what and how is being done, for private use/reuse and for sharing selected parts with collaborators. It is an intelligent shell that automatically logs user's shell sessions. Sessions are uniquely tagged and stored in local or distributed backend repositories (ASCII flat file or Subversion or CVS based) and can be extracted and reproduced at any time by the user who created the session or by collaborators located anywhere in the world.
UDPCast allows to send data simultaneously to many destinations on a local net. This can for instance be used to install entire classrooms of PCs at once. The advantage over using other methods (nfs, ftp, whatever) is that udpcast uses Ethernet's multicast abilities: it won't take longer to install 15 machines than it would to install 2. The tool comes with a busybox bootdisk for easy loading of the tool. However, udpcast can also be started from the command line of an already installed system, and can be used for other purposes than just system installation.
