Gif of the livestream. (where I lost)
I went to a Meetup that was from the people of NLHTML5 and because CSSDAY was the day after, they made a pre-conference. It was very informative and alot of cool stuff.
This pre-conference was well organized and really laid back! There was a Talk about machine learning and a talk about Browser API's WOAH. Well.. you just need to read my article!
