I am just somebody living in Sydney, Australia.
Sometimes I talk at conferences or meetups. When I do I put an entry on the talks page, with links to slides & code.
You'll notice at the bottom of the page a link to Some rights reserved. I strongly believe that content we (all humans) create should first and foremost be usable to encourage further creation. As such I license my content under a creative commons "Attribution-NonCommercial-ShareAlike 2.0" license, and most photographs (on flickr) from 2007 onwards under an creative commons Attribution 2.5 licence - feel free to use it. Code is, where possible, given away under a BSD-style license.
