So I gave a talk at San Diego Drupal Camp (SANDCamp) and Midwest Drupal Camp (MidCamp) 2015. It was called 'PHP Code Analysis Through Unit Testing.'
The MidCamp page is here: http://2015.midcamp.org/session-proposal/php-code-analysis-through-unit-...
It has a link to the video recording: https://youtu.be/ebygSeVz5vQ
And there's also a link to a joind.in page for the talk, where people can rate and write reviews: https://joind.in/talk/view/13801 At first I was a little nervous about the joind.in part but apparently people liked it. We do tend to like tools that tell us we're doing well, don't we?
The SANDCamp page is here: https://sandcamp.org/session/drupal-8-php-code-analysis-through-unit-tes...
You can see the evolution of the talk description in the two weeks after SANDCamp.
I also gave the Composer talk at SANDCamp: https://sandcamp.org/session/enough-composer-be-dangerous
It's basically the same information as my 'blog post here of the same name: http://mile23.com/content/enough-composer-be-dangerous
