Greats collections of "trips". This kind of talks where you say : "I know that… also that… that also", until the moment you fall like : "WTF? we can do this? OMG, coooool, i’ve waste so much time to do X the (wrong longer unreadable) way"
Overview of way to deploy apps. That was well explained.
Ryan is just a great speaker, even without slides the subject was entertaining. I've met the same enthusiasm you see when it merge you pull request.
Nothing weird in this tricks, they are just healthy thing, and not only for developers. Great talk, but will gain to be a little more dynamic.
Great to here about feature (toggle|flag|switch|whatever) at the Symfony level.

Spectacular
Slides hold too much explanation, that was a little bit difficult to keep concentrated. On the other side I were really waiting for things that will makes Varnish shine.
