Sirix is a versioned tree-based storage system. It provides Snapshot Isolation through MVCC and is best suited for flash-based storage. The tree encoding is suited for heavy update operations. It provides diffing algorithms either to import diffs between currently shredded (imported) XML documents to update a tree structure or to get the differences between versions of a tree structure. A GUI provides several visualizations for comparing imported tree structures.
PIMF (Php Is My Framework) is a micro framework for PHP that emphasises minimalism and simplicity.

JsonRpcPhp is a class that sends HTTP requests to a given JSON RPC server to call a specified function, passing any additional parameters. It can also send multiple JSON RPC requests and return the results of all calls. Another class can process server requests by registering a given object of service class and dispatching requests to be handled by that object.
EZDM (ezdungeonmaster) is a simple set of tools for dungeon managers, targeting AD&D 2nd edition rules. It's not an RPG game, but some helper tools for people DM-ing real games, and is designed not to get in the way of roleplay and storytelling, but simply help do the math during encounters and leveling. Dice rolling can be done by the computer, or the tools can be set for manual dice, in which case you simply enter the results of the roll. All game data, charts, and character sheets are stored in JSON format. The EZDM kit defaults to using a simple dialog-based GUI which requires easygui, but a console interface is also available.
WaldScan is a PHP class which recursively scans a given directory for a list of selected file types. It has many uses for any Web page which serves files over HTTP/HTTPS, for a CLI program which does batch processing of files, or in cron jobs for caching file data for faster access.
