Marko is a simple toolset that allows you to create markov chain databases of a corpus (or two) of text and then allows you to compare unknown texts to these databases. For any two marko databases you can calculate the probability that the unknown body is related to one over the other. Possible applications include intelligent mail filtering, plagiarism detection, and historical research.
Axis runner is a 3D game inspired by the Apple II game "Lode Runner". It features a built-in graphics engine and runs fine without hardware acceleration. All direction is relative as characters climb up on the walls and ceiling, reminiscent of the fighting scenes in movies such as "The Matrix".
Conntrack Viewer is a Perl script to view masqueraded connections using 2.4 Linux kernels. In 2.2, it was extremely easy to view this information using 'netstat -M' or 'netstat -- masquerade', but this is no longer supported. This program interprets information in /proc/net/ip_conntrack and presents it in a legible format.
WBL is a really simple tool that can be used in a .qmail file for managing a white/black list of email addresses. It serves as a pre-filter to allow known-good friends and associates bypass the usual gauntlet of filters. Note that WBL is not intended to be a spam filter, it is simply an easy-to-use whitelist/blacklist management tool that serves to keep email that you really want to see out of your normal filters.
