PLWM (The Pointless Window Manager) is a highly modularised window manager written in Python. It has no configuration files; instead, you combine Python classes to make the perfect window manager for yourself. This is not a window manager for non-programmers. The feature list includes point-to-focus and sloppy-focus, outline move, resizing, deiconifying, views (extremely powerful workspaces), and multihead support. PLWM is controlled completely from the keyboard.
Narval is a framework dedicated to the setting up of intelligent personal assistants (IPAs). It includes a language, an interpreter, and a GUI/IDE. It is based on artificial intelligence and agent technologies. It executes recipes (sequences of actions) to perform tasks. It is easy to specify new actions using XML and to implement them using Python. Recipes can be constructed graphically (without programming) by linking blocks representing the actions.
Python-mcrypt is a comprehensive Python interface to the mcrypt library, which provides a uniform interface to several symmetric encryption algorithms. It is intended to have a simple interface to access encryption algorithms in ofb, cbc, cfb, ecb, and stream modes. It supports algorithms like DES, 3DES, RIJNDAEL, Twofish, IDEA, GOST, CAST-256, ARCFOUR, SERPENT, SAFER+, and more.
pyos-chess (Python chess module) does not know how to play chess, but does understand the rules enough that it can watch moves and verify that they are correct. It features high abstraction, understands various notations (including algebraic, long algebraic, and standard algebraic notation), does disambiguation, and supports saving and loading the state of a game.
MPy3 is a full-featured, modular, configurable MP3 player system aimed at jukeboxes or car MP3 systems. It can play MP3s via rxaudio or mpg123, take input from a keyboard (tty), LIRC, or joystick. It does output through a CrystalFontz LCD directly, or through any LCD that LCDProc supports, or even through X. It features playlist support and support for controlling the mixer (using aumix). All of the inputs, outputs, and other functions are controlled via a number of modular libraries which can be used in other projects as well.
NuxUserGroups is a Zope product that adds the notion of groups of users. Groups provide a level of indirection in the user -> roles mapping, which provides greater flexibility. The groups are defined and managed in the User Folder. They are then used at the local roles level, where you can define an additional mapping of groups -> roles, thus giving the users who belong to these groups additionnal local roles. A workgroup can be defined simply and managed in a centralized manner.
