StoryText (formerly PyUseCase) is an unconventional GUI testing tool written in Python. It currently has mature support for PyGTK, beta status support for Java Swing, SWT/Eclipse RCP, and Tkinter, and very basic support for wxPython. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates it into the current GUI layout. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it, so as to use that as a baseline for text-based testing, using e.g. TextTest. Instead of requiring the tester to add "wait" statements by hand, it includes support for instrumenting code so that "waits" can be recorded.
BleachBit deletes junk to recover disk space and maintain privacy. It rids your system of old junk including cache, Internet history, temporary files, unused locale files (better than localepurge), logs, and cookies. Designed for Linux systems, it wipes clean 50 applications including Adobe Reader, Bash, Firefox, Flash, OpenOffice.org, Opera, Real Player, Skype, and more. It shreds files so that they cannot be recovered, and it wipes free disk space to hide insecurely deleted files. It offers both a simple PyGTK GUI and a command line interface for automation.

Omnitux aims to provide various educational activities based on multimedia elements (images, sounds, and text). Possible activity types are associations, puzzles, counting activities, etc. There is support for multiple languages and multiple screen resolutions (by using SVG vector graphic files and high quality bitmap files). Omnitux activities are described in XML files, so it is possible to create new activities without modifying the program.
