Great story, lots of good takeaways
a good point of view foreach framework
+1 to Stefan's comment.
Interesting story. I had expected more information on Redis as it had quite a prominent place in the title. Nevertheless, an interesting timeline of (startup) tech problems
Good presentation on vagrant and pupet. Maybe more symfony examples.
Entertaining and expressing principles (such as composition vs. inheritance) in a concise and new way. From an object-oriented point of view, it could improve its cohesion as there were lots of topics for a single session :)
This is not very good topic to talk about, because all can be summarized in few lines of NEWS file. And 1h is way too much for it. Thus bad choice for Keynote. But this is more relevant to organizers than Julien.
About presentation itself. I would like to see more examples or some notes on what was planned for PHP5.5, but did not make it and if it will be part of 5.6.
More code examples or more 'this worked and this did not' would be useful.
Good talk, great presentation
