Doing real code which works in less than an hour is really challenging. Good example of "from scratch" app development with promising ZF2 framework.
Volker's talk was one of my favourite, engaging and inspiring.
A lot of useful hints; good presentation
A lot of good tips and optimization tools
The problem is not the talk but PHP 5.5.
Best talk of PhpDay 2013
Next time please avoid Live Coding
Good talk. Next time go in depth with Apache+Php memory issues.
Really enthusiast of Windows Azure presentation. Come on, don't blame MS, we wouldn't be here without its vision of a computer on everyone's desk. I use Ubuntu, I develop in PHP and I'll give a try to Azure which seems to very promising technology without the complexity of Amazon's Services.
