I recently presented a talk at the Debian miniconf in Cambridge. This was a new talk explaining what goes on in a web browser to get a web page on screen.
The presentation was filmed and my slides are also available. I think it went over pretty well despite the venues lighting adding a strobe ambiance to part of proceedings.
I thought the conference was a great success overall and enjoyed participating. I should like to thank Cosworth for allowing me time to attend and for providing some sponsorship.
