Excellent introduction to Symfony2 as a component framework. The speaker is clearly well-versed in the subject, and presented it in a clear and concise manner. Well done!
Really enjoyed the keynote. Liked that description of php as "frictionless".
Very good general introduction to a number of libraries available for PHP. The libraries and examples of their usage were well chosen, though I think it could have been improved by including a slide with the library's repo/website and a short bullet-list of it's most compelling features.
Great talk on REST. I have to agree with Stefan, the intro/beginning was a bit long. The talk gives a great view on how people should be structuring the APIs that are pretty much self documenting/linking.
Not the liveliest talk but Michelangelo (not a Microsoft employee) had a well prepared presentation (really liked the video tour) and shared his professional experience with Azure. Not highly technical (ie no code). Recommended for anyone sitting on the fence or leery about Azure and/or Microsoft in general.
Excellent overview of LESS.
Awesome talk illustrates how annotations work.
A good keynote.
I felt it took a round about way to get to the points a couple of times, but I did like the final outcome.
