Especially the second talk was close to my heart as I think it is high time us developers take back HTML5 from the marketing people. HTML5 is the evolution of our web technologies, not another flashy add-on to already badly used outdated practices.
You can find the Slides of the talk on Slideshare:
The audio recording of the talk is also available on archive.org.
The organisers promised that the video of the talks is available soon.
I am also going to write a detailed post on Mozilla once the video is available.
