During WWDC week I talked at NSConference MINI, a one-day conference organised by Scotty and the MDN. The videos are now available: free to attendees, or $50 for all 10 for non-attendees.
My own talk was on extending the Clang static analyser, to perform your own tests on your code. I’m pleased with the amount I managed to get in, and I like how the talk managed to fit well with the general software-engineering theme of the conference. There’s stuff on bit-level manipulation, eXtreme Programming, continuous integration, product management and more. I’d fully recommend downloading the whole shebang.
