As this was your first talk it was really good! But next time try a live demo that would be even better.
Maybe go into detail about the annotations as I think not everyone got that part at first.
Very interesting approach, and pleasant presentation style
A good overview on integrating SOLR search using apachesolr and related contrib modules. Showed all the basics and had some useful pointers to more advanced use (proximity and location aware search). And the live demo was good (though you prepared everything in advance taking the fun out of it for the audience :p).
This talk had a last minute change - covering javascript as a language - and it showed... Too much swearing - if you ever intend to go to the US or UK - and it was hard to follow at times. A major letdown, it might have been better to stick to the original topic (which most likely would have been more interesting).
A 2.5 (rounded down because we can't give 0.5 points) for the effort...
Great overview of mobile web development, mentioning the tools of the trade and giving sound advice : mobile first!
Good overview of how backbone.js works and how it is tied into Drupal 8. Everything you need to get started was covered.
Great talk on CMI and how it will work in Drupal 8. Really looking forwarded to this, because it will make deploying changes a lot easier! Really enjoyed seeing some good use of Symfony2 as well, keep moving ahead!
