Good fun talk from an enthusiastic speaker. (Thanks for Xdebug)
Well presented but didn't feel relevant (with chef/puppet/composer etc). Also an introduction to yum probably wasn't needed. Still, I learnt about yum history!
Very enjoyable and a good introduction on how and why to contribute to open source.
Good solid talk on scaling websites but not much Symfony 2 content.
Very enjoyable and well written given the fact that Davey must have submitted before 5.6 features were released. Some features look really interesting (the debug magic method and variadics), and discussion on HHVM is always interesting.
Shamefully I actually thought that a firehose was something else, but I really enjoyed seeing that PHP can be used at the firehose scale.
Wow - I had no idea that the Intl extension was so extensive. Many thanks for a super-informative talk.
