Thanks for both hints, i am going to bear them in mind the next time :-)
I enjoyed this talk, stories are a good way to keep people interested in what's happening on stage and not on their laptops. The speaker was energetic, the slides were pretty, and most importantly, the topic interesting and communicated well. I didn't like that he kept talking to his friends(?) in the audience, and that he didn't repeat questions from the audience when asked without a microphone.
All in all, at the end of this talk I felt like I had learned something, and I was eager to try out some new stuff.
very complex subject. it was hard for me to follow. maybe more code examples would explain the stuff better.
This presentation gave me a lot of things to look up, and reminded me how interesting this topic is! I do think some of it would have been better backed up with illustrations, there were a lot of numbers and concepts, and personally I grasp things better when I see a picture how it works. I still remember parts of the talk, and what I will use the information for - and it's been days since the presentation, so good job:).
