I am just a guy who is currently 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.
