Caching on the edge
Great tutorial, very interesting content and a very good explanation of the mechanisms. I did learn quite a few things! IMHO, I think the talk could've been improved in 1 of 2 ways, either remove the whole interactive time, and just make it a presentation or make the interactive time larger. I did not really like the interactive time, after all the info was given we only had a few minutes to just "play around" with it. I think It would be nicer if we had less explanation beforehand, then some more interactive time to figure out things for ourself and try to get stuff to work. Then after that, the 'solutions' could've been shown and/or explained. Also, I liked Silex.

Isolation for your tests
Since the "Caching on the Edge" tutorial finished early, I stepped in on this tutorial at the end (last hour). I was able to grasp some of the concepts, not all was new to me but it did give me a few new pointers in writing tests, especially when dealing with parts of the software that are external. I had a difficult time understanding what was said due to the accent of the speaker, this in combination with the very very high speed made it almost impossible to understand any information presented. I noticed the following: when Giorgio asked if there were any question, there were pretty much none. I do not think this was because the information was so clear, but because because most people had no clue what he was talking about and wanted to "get it over with". Perhaps not everyone shares this opinion but I have talked to a few people that attended the whole presentation and definitely agreed on it. A possible improvement would be a slower pace for the information presented, it would give the attendees time to "translate" the spoken information and then digest the actual content of that information. My rating below is about the content and the way of presentting the information (using slides & flip-over, enthusiasm of speaker, etc.). I did not take the above problems into consideration for the rating.

Advanced OO Patterns
Great talk, good content and a good reminder on that Design Patterns are not the holy grail.

Making the new everyday things
Excellent! One of the best presentations I've seen. This had a lot to do with the humor in the presentation. If somehow, the software world doesn't work out for you, you could still do stand-up comedy. Not a technically hot topic, but very inspiring.

Searching with Solr - Why, When and How
It was an okay overview of Solr but I it could use some more in-depth information it seemed more like a business perspective of Solr. Perhaps my expectations were incorrect. The presentation could use more energy. I heard that the speaker DOES have that energy, it just did not work out so well this time. So Paul, take not of some tips in all these comments but do not feel too bad about any negativity. You can do it :)!

Developing & Deploying High Performance PHP Applications
The talk was pretty much Sales focussed, it did not belong with the great talks I heard this weekend. Most information I heard could've probably been read in the FEATURE list on the Oracle website. I did see a few code lines in the slides, but they seemed to be in there just to make the presentation appear technical. Improvements: The speaker could have selected 1 or 2 great new oracle products and then show us how they can be used in the real world (code examples, some cool features and how they work). It would still be a way to promote the use of those 2 oracle products, but the technical details would keep the crowd happy.

How XHP Revolutionized Frontend Development at Facebook
Interesting talk, nice to see some "under the hood" information on Facebook and very well presented. Also the level of technical details was good. 4 thumbs up! I can imagine that implementing XHP was a LOT of work, but I could not help but just seeing a polished SMARTY templating engine.... but perhaps that is just me?

The missing link between IDE and webserver
Sounded interesting, but I felt it was just a VM image available for download. The VM can easily be implemented by anybody with some common sense, a little imagination and an IQ of 750 :). But seriously it just sounded like a very well implemented VM image if it were more than that, then the point did not come across. Presentation was very good.

Why Google Maps sucks
Interesting project, I had never heard of it. Honestly, I do not think it really belonged in the DPC Uncon. I actually did like the way of presenting it. It was chaotic but very energetic and fun to listen to which made up for the chaos. 1 thumb for the contents, 4 for the presentation.

PHPSpec - BDD for PHP
Very interesting, I agree with Stefan there should be more attention to this. I have a vague idea that perhaps the Behavior-driven approach works better than TDD to sell "testing" to managers and customers... It somehow sounds more real to non-technical people to show them a report that shows that the application indeed behaves the way it should. HINT HINT: I would like to see more of this in a future conference :).

Advanced OO patterns
Good talk, great content. Although too much info which made the presenter rush through the material. I agree finding more ways to help keep the audience awake besides the hand-raising. But to me it was not a real annoyance, perhaps I am more patient ... or just as boring :). I missed the reason as to why Singletons are bad, I think the presenter said he would explain this, but I don't believe he did... did I fall asleep?

DPC Conference Social
Music was way too loud for the social, difficult talking to one another but the drinks were great :)! The location was pretty good, very accessible by public transport. It was great to see my old Ibuildings-colleagues again and I also met a lot of new very nice people. I do think that the social is something to keep for each DPC. It is a great way to meet other developers, both big- and small names in the PHP world and talk about both tech and non-tech stuff. PHP Developers are great, they almost seem like real people :)

Building an application with Sencha Touch 2
It was a nice session and we've got a very good introduction on the possibilities of Sencha Touch 2. Which was easy to follow even if you did not have any experience with Sencha (like me). Unfortunately most attendees did not prepare for the talk and did not download the SDK and tools so we wasted a lot of time waiting for everyone. This in effect forced Tommy to pick up the pace of the talk so we did not really have time to try all the examples he gave. Perhaps next time having a few USB sticks ready with the installs for various OS might help?

PHP in the Dark - shell scripts, daemons & parallel processing
Great talk, I too was missing a bit more hands on, since it was a tutorial. At the start of the talk it was too simple, but the rest of the talk gave me quite a few new insights, especially on parallel processing and such. I also like the live demos. The speaker seemed a bit nervous, no need, you did a great job!

SPL in the Wild
Content of talk was great, learned a few new things about SPL. I agreed the scrolling was not helpfull and the anchor-tip would be nice to use. Personally I was not interested much to see real-life-examples of the SPL implementations, any example of an implementation would've been fine. Also, they would make code examples shorter and faster & easier to read by the audience, which helps if you only have little time for the talk. And, yes, I need to use SPL more. Thank you for reminding us. On a non-related note: I missed the "Iterator"-drinking game at the social ... oh well, perhaps next year.

Designing Beautiful Software
Great talk, but expected it to be a bit more advanced, but that might cause (like others mentioned) it to lose what the talk was all about "improving code for extensibility and maintainability". Nevertheless well presented.

Coupling Cohesion and more SUDO science
Well presented, and easy to follow and nice to listen to, I do have some feedback on the contents though. The talk seemed more like an overview of the different types of coupling and cohesion that one can have in his application and less about which way(s) are better. It would have been nice to see some bad solutions in terms of cohesion and then show how to make them better in a few different steps. It would get the point across better on where you should focus your efforts when designing your solutions.

Let's build a parser!
As expected, very well done Boy. Thank you for reminding me of some of the stuff I've learned during my education, never expected to use it anymore. You told me it was going to be heavy stuff, and yes it indeed was. It took me a bit of effort to follow along especially since I did not know a lot of the terminology that was used heavily throughout the talk. Not sure how this could be improved because you explained them thoroughly beforehand. You did a great job talking about a difficult a subject and making it understandable (for the most part) I will surely delve into this a bit more to improve some previously made parsing solutions (that were built using regexes) with a more robust solution.

HTML5: All about Web Forms
Great talk on HTML5. I did not know that it is actually useable already, which is the only reason I stayed away from it ... till now. Thanks for pointing that out to me (and the coolness of HTML5 ofcourse). The informal way of talking, cursing about browsers (especially IE) made it a lot of fun to listen to. Keep up the good work and have fun at your talk in New Zealand.

Beyond Testing
I am sorry to say but I found it really hard to follow the story due to the accent of the speaker (my lack of sleep after the social the night before did not help either). Fortunately the slides were clear enough to understand the concepts.

Machine Learning - Support Vector Machines
Awesome talk, simple explanation of a complex subject. More depth would've been nice but there was not enough time for that I think.
