You can watch the video on YouTube, or here in the embedded player.
The video is published as 1080P so be sure to open the video in full screen to get the best quality.
I recorded the video with ScreenFlow and used my portable Roland R05 audio recorder to record the audio. I put the R05 on the podium next to my laptop during the talk, and aimed it up at me. The audio came out amazingly well, proving just how good this little device is. In a room of well over 100 people, with constant noise and echo, the R05 picked up my voice quite nicely without the noise.
In addition to the video recording, you can get the Keynote slides and source code on my Github repository. If you don’t have Keynote, though, you can see the slides in my SpeakerDeck account as well.
