Over the years I have contributed via mailing lists, online forums and various development platforms (eg. Sourceforge) to the development of web standards such as RDF (an aspect of the semantic web), friend-of-a-friend (FOAF) and anything else that once looked like it might have been either useful or interesting.
Former webdev projects
Julia Users Group - Berlin a simple focal point for Julia users in Berlin.
Luebeck Social Community using Ning.com as a framework I created this social network for making friends in Luebeck.
British Mathematical Colloquium/Irish Mathematical Society conference, 2009 (I provided the backend which dealt with subscriptions and payments)
Statistics E-learning Site - Written in ~2004, this was a highly advanced e-learning website, developed in php, which incorporated a hand-written mathematical interpretter. Lecturers could formulate questions in a mathematical script, including a randomisation based on student ID, and students received individualised questions which were then graded automatically by the computer.
