Since I hadn't learned anything about recursive decent parsing before, it was quite useful for me. I definitely learned new things which might become useful to me at a later moment.
I have a few suggestions though (speaker + DPC orgs)
1. The talk was quite short and you could elaborate more on this topic I guess. There is a lot more to learn! What are other parsers you could use (php-parser or phpphp)?
2. The talk was rated for an expert level, but you could dive into it even more. For me it was certainly useful, but I couldn't hear my brains crack yet. For these kinds op topics it allowed ;)
3. Only "v1" showed the code how to parse "Array()" but all next parts didn't return to this point. I think it makes the talk more concise when you show how the new methods are used to get the new parsing rules to work. A little bit more php code, esp how you could use your parsing api, will help a lot.
For the organizers: the speaker from the adjacent room could be heard during Boy's talk. His microphone was probably too loud and I sat almost at the front row, but it was sometimes distracting. Perhaps this could be improved next time.
Impressive how casual she goes through the dungeons of GIT like it's an afternoon stroll. First time demo style she says but I find it hard to believe :) Well prepared and smooth.
loved the new format and the way you handled the crowd. even as an experienced git user I picked up a few new tips. great job.
Inspiring and fun talk, Evan's advice about site projects is certainly true!
Very disappointing speach. It was more about security issues as actual html5/messaging.
Funny guy with a nice store.
Liked the new "live demo" approach. Keep up the great work!
Nice presentation !
Sorry there was so little time! Very insightful and live demo'ing went perfect. Loved the "text adventure" bit as well
