Julien gave an excellent overview of how memory management works in PHP, and was clear and concise with his explanations. I have a much deeper understanding of memory use in PHP now, and it was easy information to digest.
Good view behind the scenes. There could be more tips for devs, how to write memory friendly code
This was a great talk about the problems inherent with most dashboards and monitoring systems, and how to overcome them. Lorenzo did an excellent job of tying our cognitive biases into strategies for building useful dashboards. The talk was well organized and well presented - great work!
Good presentation. Interesting details about how composer works. More about satis would have been nice
The portion of this talk that actually went over the new features of PHP 5.5 and when/how to use them felt pretty small. I would have liked to see more real life use cases instead of trivial examples. It gave a decent broad overview but without much depth.
Great talk, it could have been even better if you had given an example of how to fix dependency issues (because they will occur eventually). Learned some new little features as well (probably because I haven't read the docs recently :p). One minor note though : afaik you can actually update a single dependency (or just a few you wish to update), using composer update vendor/package (I got the impression you mentioned that that was not possible).
Better and more examples of the new features please
Great talk, though you rushed a bit through it. You gave lots of pointers, using libs that already have been tried & tested (a major plus), and even covered ACL integration (a -very- small overview of how the acl support works would have been handy for those who don't use it yet though).
A small live demo - demoing the source code you presented in action - would have received a 5 thumbs up.
