Projects I'm involved in

www.arigora.com
A website framework I have developed. Arigora provides a skinning system which lets you design a single skin which works with MediaWiki, Wordpress and Arigora pages. Arigora optimises content delivery with caching and by reducing the number of HTTP requests. It provides a framework for cross browser compatibility. Ocf.co.nz is running under the Arigora framework.
Greenstone Digital Library Software
www.greenstone.org
Software for creating and distributing libraries digitally. My day job is working on Greenstone and the things around it like the source code management, bug tracking system, software installer and the Greenstone website.

sourceforge.net/projects/search4j
A little open source program I've written in c++ which locates java on a users computer and reports its location or uses it to run a jar. Works on Windows, Mac, and GNU/Linux.

envi.arigora.com
A multi-platform, open source tool I've created for running tasks in controlled environments. For example, use it to create a task which compiles a java program with an alternative JDK. Running `envi mytask` processes the task named "mytask" in its own special environment.
