Fast overview of some of the new PHP 5.5 features. Learned that as of PHP 5.5, APC will be dead (PHP 5.4 will still be supported though, for a while). Let's hope opcache works a bit better regarding execution of stale code (so that you don't have to fiddle with config flags to make it work correctly).
More real case studies will be usefull.
Interesting and informative, covering some somewhat more advanced features and inner workings of composer. The talk was well organized and presented. Perhaps the speaker could have been a bit more enthusiastic. :)
Usefull talk for every php developer.
Unfortunatelly, didn't cover anything you can't learn from the summary of new features on php.net. Talk was also too slow.
Good talk with great content information
Bad presentation in terrible english :(
Very good talk on ZendMM, and more generally on PHP internals memory management. Always good to know what happens under the hood. Clear and detailed, I got quite a few bits from this talk.
