Webplay creates, from a collection of MP3s and Ogg Vorbis files (indexed from a directory or MySQL/PostgreSQL database), a Web-based jukebox with support for multiple independent streams. If Lame/oggenc are available, it can change the bitrate or codec of a file in real time to a selectable value. Each user controls their stream via a Web interface and can skip back, forward, or to a specific track; increment or decrement the bitrate; and check the current playlist, song, or bitrate. Playlists can be looped, randomized, played locally on the webserver, edited, deleted, reused, or renamed.
Raja (RAy tracer in JAva) is a complete, object oriented ray tracer written in Java. It fully supports transparency, intersection, union, complement, mirroring, basic anti-aliasing, and exact acne correction. We aim to do a complete, easy to use and distributed renderer to do images or movies over a network of heterogeneous computers.
Grok is a library of Java components for performing various natural language tasks. These include several preprocessing tasks, chart parsing, a large categorial grammar for English (induced from the Penn treebank), and some knowledge representation components (basic coreference, salience tracking, etc.). The library also has a companion kit which provides a GUI interface to the components, several of which are implementations of interfaces in the Quipu OpenNLP API.
