I just got to edit and upload the slides and screencast of my talk at campusparty europe, so here you go:

Campusparty are live streaming and recording the talks. Here is mine but sadly enough there is quite a chunk of audio missing and it seems To be out of sync later on.

I also recorded my own screencast on YouTube with audio that is a bit on the loud side so turn down your headphones:

The slides are available on SlideShare:

There is also a slide version with notes available on Slideshare.
