TinyIB is a lightweight PHP image board which emulates the functionality of 4chan. If you use MySQL or SQLite, you can use it to create an efficient setup able to handle large amounts of traffic. If you don't use a database, it can store posts as text files for a portable setup capable of running on virtually any PHP host.
TorrentWatch-X is a Web-based tool to automate BitTorrent downloads. This is a fork of the torrentwatch project, now also with NMT support. It is meant to run on Linux and Mac OS X with different BitTorrent clients (for now, only Transmission is supported directly) and make it work in all Web browsers. It supports RSS feeds from a few torrent sites that offer TV shows. It can save torrent files in any folder, so any torrent client can pick it up. It can tell Transmission to save data in any folder. It can tell Transmission to stop when a certain ratio is reached. Authentication with Transmission is supported. Your own RSS feed can be added.
The Exquisite `df' (xdf) is a souped-up version of df(1) rewritten from scratch and focused on flexibility of field selection and output format. It offers HTML and CSV outputs, besides the traditional text-based console output. It is fit for system administrators who are tired of post-processing df(1) output through shell or Perl scripts in order to avoid broken lines or to get a simple total/summary line.
