GTK+ Recent Files Scrubber is a compact, lightweight Python script which uses GTK's RecentManager to watch for updates to all globally-available "Recently Used" lists (the ones which appear in Open dialogs and the like) and filter out anything in the folders you blacklist. Blacklist entries are hashed to make reading the blacklist not worth the effort.
GTKMathplot is an interactive plotting program based on GTK+ and the Cairo graphics library. It can display bidimensional curves, tridimensional curves, and surfaces from Cartesian or parametric equations describing the mathematical objects you would like to visualize. It is designed to be intuitive for high school students with good mathematical knowledge. University students of engineering, physics, mathematics, or natural sciences should need no explanation at all to start using it proficiently.
Grab Downloading Flash Video is a Bash script designed to be called via a Linux GNOME Desktop custom shortcut key while a Flash video is playing in your Firefox or Chrome browser. The script attempts to find the file being downloaded, waits for the download to finish, and then copies it to a configured directory. Prior to Flash 10.2, it was easy to find the file yourself in the /tmp directory. But starting with version 10.2, this script is more useful because the file is deleted but internally still open. Note that this is not a universal solution. Some sites, such as YouTube, make it easy to find the URL of the Flash video file. In those cases you may have better success using a download utility such as 'youtube-dl'.
