From Drupal and Moodle, right through to a Git versioning system and Perl modules on CPAN, we contribute back to over 175 community open source projects. This list is in order of the number of projects contributed to.
iRATE radio (http://irate.sourceforge.net)
iRATE radio provides users with a powerful new way to find and download free, legal music online. Users rate tracks based on their tastes. The iRATE server then selects other tracks to send to the user from a database of over 50,000 freely downloadable songs by correlating the user's ratings with other users', and finding people with similar tastes. Unlike streaming audio, iRATE saves the tracks to the user's hard drive. This means that playback is smoother, without the typical problems associated with streaming media, such as high bandwidth usage.
jQuery plugin for doing animated title sequences (eg: like movie credits)
jQuery plugin to make elements of a web page/app draggable by mouse or touch.
JRobin is a 100% pure java implementation of RRDTool's functionality. It follows the same logic and uses the same data sources, archive types and definitions as RRDTool does. JRobin supports all standard operations on Round Robin Database (RRD) files: CREATE, UPDATE, FETCH, LAST, DUMP, XPORT and GRAPH. JRobin's API is made for those who are familiar with RRDTool's concepts and logic, but prefer to work with pure java. If you provide the same data to RRDTool and JRobin, you will get exactly the same results and graphs. JRobin is made from the scratch and it uses very limited portions of RRDTool's original source code. JRobin does not use native functions and libraries, has no Runtime.exec() calls and does not require RRDTool to be present.
Kannel is an open source WAP gateway. It attempts to provide this essential part of the WAP infrastructure freely to everyone so that the market potential for WAP services, both from wireless operators and specialized service providers, will be realized as efficiently as possible. Kannel also works as an SMS gateway for GSM networks. Almost all GSM phones can send and receive SMS messages, so this is a way to serve many more clients than just those using a new WAP phone.
