I've given this talk in a few places, but it was a privilege to deliver it again at OSCON! It's a very practical walk through using curl, Wireshark and Charles to work out what's going on at different levels of your application by inspecting the HTTP traffic.
An advanced git talk with a twist - you get to choose your own adventure through the talk content to work out what you want to see! This talk is fun because it's never the same twice.
No slides (sorry) because they only show the adventure - the actual git content is a combination of scripts (to get the repo into the correct state very, very quickly) and the rest is demo. This session wasn't recorded.
Keynote for Joomla! and Beyond. I doubt the slides make much sense but they do have some citations at the end. Mostly this talk is about community, karma, and responsibility.
Update: now with video!
This talk was given in very different ways on two consecutive weekends: first at DrupalCamp Scotland in Edinburgh, and then at phpDay in Verona. Two different crowds, different events, but the same message. Upgrade, FFS :)
A short talk at APIStrat in Amsterdam about the joind.in API.
