joyd is a very flexible program that allows you to execute commands via a joystick or joypad attached to your computer. One simple possibility would be to reboot when your keyboard is hung. It can use any device supported by the Linux Joystick Driver. Helper applications allow you to test the joystick status in your own shell scripts.
whatsnewfm is a filter for the daily freshmeat newsletter. It shows only news items that you haven't seen before (so you don't have to read about every update of applications that you aren't interested in). You can also set up a list of "interesting" applications where you want to be informed of every update.
p0rn-comfort consists of several support programs for browsing image-gallery sites. It includes a proxy which enables blacklisting of thumbnail sites on-the-fly. It also supports queueing of entire pages for download and fetching them at a later time. Queuing can either be done manually (directly from your browser) or by an automated download script which can also follow links between different galleries.
Could be done with BitTorrent alone
Instead of mixing HTTP, FTP and Torrents, one could just use Torrents to get the listed benefits: Torrents let you address multiple trackers, so there is no single point of failure at that point. Instead of having 5 HTTP or FTP Mirrors, you can deploy 5 "always on" seeds for your data on different hosts. That way, everyone has the chance to always reach a 100% seed. I don't see why HTTP and FTP should be added to the mix, they just make things more complicated IMHO.
freshmeat ][ newsletter format
whatsnewfm 0.4.0 is needed to parse the new freshmeat ][ newsletter format. You can download it from my homepage (http://www.cgarbs.de/whatsnewfm.en.html). As soon as the stable branch shows up, it'll also be added to this project page.
