Talk comments

Very interesting in depth talk. I can imagine that without a little bit of knowledge on PHP's internals and C one could have gotten lost quite fast. Still it is very good to have more advanced topics on conferences.

As I am used from Rafael by now, a very good talk. Pretty slides, high-information density, a nice pace and structure. I can only say I really think annotations should not be used for anything else but configuration, but that's an opinion :)

Pleasant keynote, nice to hear the grumpy irl for once. I got lost a litte during the cold-war references but otherwise it was very much enjoyable.

Good presentation with some good insights in big data processing. One side note: please talk a bit slower to bring more calmness into your presentation.

Very good talk about SOLID principles. Enjoyed it.

A real good introduction to machine learning. Too me the best talk of the conference.

Good talk with a good emphasis on lesser known new functionalities

You don't need many slides but it would be beneficial to both you and your audience to visualise in one diagram what you'll be speaking about and how different components are working together. Jumping from one to another screen makes it harder to follow, especially if you are sitting far away from the presentation.

Very interesting session. I never got around to writing tests or to research them in any way. This session provided clear info about the different types of testing (unit, integration, regression, ...) and had a small intro into TDD. Overall very high quality session, only too short :(
