Did exactly what it said on the tin. Good delivery, great pacing (i.e. covering the lower portion of the top 10 quickly, and then focusing on the more important ones).
Clear and interesting talk about decoupling
Quite a technical talk, but what I missed was a brief explenation of what some of these new features exactly are. Not everyone has a background in C or other language that has things like generators and closures, so if these get introduced in PHP, you should not assume everyone already knows what they are and it's used for (which doesn't always show from a small example).
Why can I not rate this 6??? Seriously, fantastic messages were conveyed through entertaining, witty and dry humour. Having seen Volker talk before I had really high expectations, and he totally smashed through them. Super awesome closing keynote!
A fascinating insight into how these compiler thingybobs actually work. My eyes usually gloss over when someone starts talking about these complicated things, but THIS was delivered really well, and I actually understood it, yay! Thank you for not making it overly complicated.
Interesting concept. You should totally write a book about this stuff!
If you ever want to learn about HHVM/Hack, what better person to hear it from than Sara. Energetic, amusing and informative - and importantly, inspirational. There was a lot of stuff covered!
Great keynote, it was a little short, but the message was delivered, and any longer probably would've just been rambling or padding anyway. Nice.
An issue which I think will resonate with varying degrees with everyone.
