Clusters and server farms often have many nodes and very little hardware support for locating and diagnosing problems, especially if the problem involves the network interface. Helpme is a small stand-alone program that allows a node to use the standard PC speaker, both to signal that a problem has been detected and to render arbitrary alphanumeric text using either Morse code or the NATO phonetic alphabet. The input syntax allows repeating messages and more.
OBLISK (Open Binary Linux Install System Kit) aims to make any package install on any modern GNU/Linux system. OBLISK packages are sent in an appdir-like package and can be run entirely in place, but also have an installer, which makes it possible for them to be installed to /usr or any other path.
