Already gathered some presentations from the speakers by mail, but here they all are.. Unfortunaly not the sample codes. Sheets are in English so don't mind the "Netherlands" in the url.

I wrote a report (6 pages) with a quick walkthrough of the sessions I followed, if you would like to receive it, mail me (Dutch article!).
