A bit basic, but on the other hand you can't dive into all in such a short time. Respect for the live coding, always tricky. Also showed some great use of phpstorm's (I'm a big fan) refactoring possibilities.
Interesting talk giving me some insights in questions I face daily when coding. I don't agree with you everywhere, but overall we're on the same page. I agree with Sven's comment below, the switch to disco was quite abrupt. For me you could have filled the other half with more theoretics and best practices. The disco part was more an tutorial of how to use disco, which is already perfectly documented on the project's readme.
