As a newcomer to Sphinx I learned about a general idea of it. As a Solr user I'd love to hear more about differences between both.
It's really a pity that you had to face technical issues (organizers weren't prepare properly).
Excellent presentation about the do and don't of sacred cows. Agreeing with Rowan, this talk should be seen more on PHP conferences.
Nice talk. Some great new ideas about packaging and dependencies.
Inspiring talk. In our daily coding we're focusing on a clean code and possibly the best coded solutions. Presentation shown me that creating technical debt is not always a bad thing.
Really recommend to listen to Greg if you have a chance. It's awesome how good presentation can be without slides when done by a good speaker.
