The Big "Why Equal doesn't Equal Quiz"
Although this quizz wasn't any good for my self confidence, it sure pointed out once again to me what problems loose types can cause in validation. Very interesting to attend, and good to see the facts again.

Integrating symfony and Zend Framework
A very interesting presentation, up to now I've only been using Zend Framework as a component library and didn't even knew that Symfony had the same option. Thanks to Stefan's excellent explaination and the heaps of code in the presentation everything became clear pretty fast. It definitly caught my attention to go and look what Symfony components can do for me.

Role of a PHP user group
I really love the usergroup meetings, keeps me sharp, interested and driven to 'do the right thing'. I see people around me who feel like they have it all, and it's always fun to confront them with the things I've been again reminded on or learned from the community. I wish I could also give back to the community, 2 things that keep me from being very active is uncertainty (will a certain subject be interesting enough? Do I know enough about a certain subject?) and time.

Passing the Joel Test in the PHP World
Great talk, but also very interesting for managers. And I love the humor. I think it is also very insightfull for many people who get involved in the development process.

PHPillow & CouchDB & PHP
Very nice talk, I still really like the idea behind CouchDB and now my PHP is at the right version I will definitly have a look. Although as an improvement I could recommend using more real life examples of PHPillow and CouchDB so people will see how it works, what it does and how they can benefit from it.

PHP applications/environments monitoring: APM & Pinba
Although I do have lots of trust in APM and Pinba and also know these guys could give a demo that raises some oooohh's and aaahh's this time it was different. I'm sorry to say but I had hoped to see it all in action.

Get the most out of Solr search with PHP
Very interesting talk, I really need to get into the subject when I have time. Paul definitly looked like the expert on the subject, but it also was a bit much for a complete Solr n00bie like me. It still feels like implementing Solr will be costy on my dev-time.

Living with Legacy Code
Never saw Rowan speaking but he made a superb graphical presentation, funny slides and code samples (all Frankenstein-style), and also clearly explains them all. There wasn't much news on the horizon, except for one thing; I will finally get the order of steps and priorities right next time. And I bet that was the main goal of the presentation. Many developers will feel more comfortable after seeing this session because there will ALWAYS be legacy code.

Generating dynamic PDFs using Zend Framework and JavaBridge
Although Eric wasn't able to attend due to the bad weather it was really nice to see that a web-presentation at a conference can work out really well. The only 2 things missing was interaction with the facial emotions or raising hands (as mentioned on a slide *LOL*), and asking questions was a bit harder but not impossible. The talk itself started of with some Zend talk, but I can't blame Eric for that, Zend is still the company that made it all possible for us. And even though the talk was aimed at PDF and Zend Framework, the Java Bridging was the most interesting. Never knew it could be that easy! To get into the generating PDF part much more knowledge is needed on that, and I don't see myself going through that in the near future. But I still keep the possibility in mind and might have a second look at this presentation then.

Zend Framework Application Patterns - Part 1
Very interesting talk, some things are already well known but I get new usage inspirations from the examples. Zend_Navigation was definitly the highlight of this morning. The speakers are explaining really well, not much questions arise during this session. + Clear explaination + Nice examples +/- Loose examples, not a full application which brings everything together, but you can make it up yourself

Zend Framework Application Patterns - Part 2
The second part showed me a lot of things I haven't seen before. Especially the part about unit testing controllers was total awesomeness. And exactly what I needed to do next week. The live code demo was a great sub-session, I love these real life examples. A very large thanks for Matthew and Rob, they have shown me how to become a better ZF user, now all I need to do is apply this information.

Designing for Reusability
After seeing Derick talk a few times in the past I had very high expectations of this talk. And I wish I hadn't most parts of the talk were already pretty well known and didn't go into much depth. The part about traits was pretty interesting, but we're not able to use it yet. And maybe some more info about PHP 5.3's namespaces would've fit in quite well. All in all a decent talk which needs a little more structuring and some more in-depth info on the subject.

Technical Debt
This was really a very nice talk, the fast pace, the simple but useful information was really good. And although everyone keeps fighting against 'the ties' about this subject, the tool to express technical debt in money was absolutely ground-breaking for developers dealing with this convincing issue!

Graphics with Cairo
At the last minute I decided I wanted to see something else than just the architecture and QA sessions so I just walked into Michael's talk. It was pretty impressive to see that Cairo was so much faster than already known libraries like GD and ImageMagick. These are the kind of slides that convince me to look further into it. And although the rest of the presentation was mainly an explanation of the classes and methods it sure helps to get started quickly.

Database version control without pain
Harrie definitely showed us that database schema's can be controlled, the talk had a nice build-up. It started with fairly simple solutions and as the talk continued you got the picture how these can become more advanced life savers. All the questions that came in mind got answered while the talk progressed, and at the end I got the whole picture without asking a single question.

Bayesian Filtering For Twitter
Now this is one of those talks I really love, practical example, good interaction with the crowd and really some nice stuff to think about. It was nice to look into existing code, the structure and ofcourse to learn something about the bayesian filter which is applied in many anti-spam solutions.

Crash! Burn! Recover!
Cal knew how to steal the show again, and although this session had nothing to do with PHP it was great to see an application getting build up from the ground in Flex. But I'm sorry to say that I still don't see a large future for me in building these myself.

Security-Centered Design: Exploring the Impact of Human Behavior
This was the best keynote I have ever seen. Although it wasn't technical at all, it showed us all something that we surely need to know but just don't come up with between the UML'ing and programming. Although I was working on my own presentation I listened carefully and sometimes even looked up because I actually didn't want to miss this one.

APC & Memcache the High Performance Duo
This is without a doubt one of the best main-track sessions I've seen. It started off with the basics and for a moment I was scared that that would be it. But just about halfway the session all the good stuff came which made this talk a must-see for everyone no matter if you're into caching or not.

Technical Writing 101
Woohoo the crap throwing session with inflatable shit! This was great fun, and also had a core of very useful information. It really got me all warmed up to start writing again soon. But first I have to do my homework before I put it out there. Great fun, great info, great session!

Reviewing PHP Code
Sebastian is really the quality king out there, and he has showed us again in this session. Although many of the given info was already known to me it still had lots of little things which I keep forgetting or just didn't know yet. I really enjoyed this session and it was over before I even had the idea that we got started. Time flies when you're having fun.

Panel: The Future of PHP
A nice little chat with some well known speakers. Although it was much speculation and trying to find out what Scott is actually doing, I really appreciated this welcome cool-down after days of learning and information consuming.

97 Things Every Programmer Should Know
This was a fun session to start with, and although 97 tips wouldn't fit into the schedule it would be nice to spend less time per item and present more tips. Don't see this as something negative though, wanting more after seeing this is actually a good thing.

Building web services with Zend Framework
Jonas proved to be a very talented speaker. Building up his story from zero to all inclusive was great. I was very interested in his zf way of implementing services. Only 2 small notices, try to speak a bit louder when there is no microphone. And unfortunatly there wasn't enough time for the last few slides which looked very interesting.

Testing Untestable Code
This was one of my favorites, first I was looking at the most nasty tricks out there to test legacy code which you wouldn't want to touch. But the disclaimer in the end to always write good code made my day. These are no measures to take when you write your own code, but when you get into a situation where you have to inherit someone else's dirt these tricks do come in handy!

Developing search applications with Apache Solr & PHP
Very nice tutorial, as part of the crew I didn't get all of it because I still had work to do. But I caught just enough to get a Solr installation running and find the GUI to look for the things Paul teached us from there on out.

Seeing PHP through a blue azure sky
I really like that Microsoft knows it's place in web development and reaches out for that. I'm still a little awkward about it as well. But sponsoring a php conference, reaching out to the PHP community with examples like these and some more things which weren't presented at this session makes me feel that they deserve a chance!

Harness The Power Of Sed And Awk
This was a refreshing talk, while the tools have their specific goal they can be very powerful indeed. I'm one of those people who'd like to see more tools in one session (maybe in a bit less detail), so the powers of UNIX will become more clear to developers. But I must admit Joshua is a very good speaker with a good balance between fun and knowledge. I bet we'll be hearing a lot more from him.

Improving Code Quality with Continuous Integration
Let's be silly and rate my own talk from my point of view; I really liked the audience interacting and even teaching me a thing or two which I've never ran into. I felt the tech-love in the room! :) It scared me a little at first, and being tired and all also influenced my talk a bit. But it's no excuse, next time I will bring a big pile of chocolate-chip-cookies-feeling and be more fit. This feedback is actually very good since I didn't know if anyone noticed. I got that chocolate-chip-cookies feeling all over!

Advanced CouchDB
After seeing Kore Nordmann's talk about CouchDB I was very interested in someone else's view since I still didn't have the time to check it out. And Sander really has a very good talk to make things even more clear. Especially the pace of it was very good, and it was very well balanced between using CouchDB and combining it with PHP. The only thing missing was the right contrast on the slides to actually read the code. But I bet that won't be a problem anymore next time this talk is given.

How To Build Customizable Multitenant Web Applications
After seeing Stephan's first talk I was very curious what more he could teach me. And again I was amazed by his creativity on this subject. I had a pretty hard time following because of being worn out myself. But I got the good parts I bet, I do not always agree with the given solutions but they sure gave me something to think out and refine, if possible at all.

Chocolate Chip Cookies and Open Source Communities
aaawwww we got all mushy! What a very cute but also informational talk about what a community is. I also learned that I never ever want to go to jail, had some very disturbing images passing by through my head at that point! But it was a great way to put our minds at rest and leave the conference with a "feel good"-attitude :)

Joel test: how we do it
Very nice talk to see so many good ideas, the pace was a little too fast. But that was mostly due to the timeslot of 30 minutes. Also when doing this talk for a larger audience I would prefer the "You should"-way instead of the "We do"-way. Overall a very great talk and with a little work this can be conference worthy and lead to great discussion among developers!

Using Phing
Very good talk in which many of Phings power is covered, I loved to see the live examples. And just like DragonBe said, keep the examples small and DRY. It definitly got me interested to run Phing sometime soon instead of Ant. The less packages on my server the happier I feel, so if I won't need Java I can save myself a few updates of server software :)

Database version control without pain
This was the second time I saw this talk, but this time I was mostly sober. And maybe due to that fact or the fact that my memory had left me I still picked up a thing or two again (Doctrine and Phing features). It was also great to see the talk in Dutch this time. And Harrie definitely knows how to make the subject live among the crowd with great visuals and some good jokes.

Redis for the everyday developer
A very entertaining talk which gives a great introduction to Redis, adding a bit more images to the slides with just a term (if at all possible) would spice it up even more. But Ross is definitely ready for the big conferencing work!

Let's build a parser
This is the kind of hardcore talk I really miss at many conferences these days. But because it's so hardcore I'd suggest to put less text and more images in the slides. Next to that it would be better to have code snippets in the slides (maybe with the classname as the slide title) instead of showing it right from the IDE. Also I'd like to see the workings of the PDepend parser. With those additions this talk will be more than awesome!

Easy Mobile Development: Appcelerator Titanium
I was only able to join at the start of the tutorial, but Pratik did a great job, he helped people with getting the setup right in a very fast and efficient way. The prepared Voterlab code is something which I will use as a reference for a long time to see how to get things done. Also the pace of the tutorial was great, it started of playing with components and moved to events, so you get to learn things step by step.

Selectors, gradients and animations
Estelle wasn't actually doing a tutorial, but she stood up when one of the tutorials was being cancelled (KLM wasn't really helping...). And because the subject was a whole lot different not many people attended. But I got a surprise... THEY SHOULD HAVE!!! This was awesome stuff! Estelle gathered materials from her talks and did superb job! I have a background as a PHP developer, and since I'm using Sencha Touch I'm a bit more into CSS, but Estelle also showed that CSS selectors aren't just meant for CSS tasks only. You can use them in jQuery or even drop jQuery and use all this great info directly in Javascript. The second part about gradients was fun, I'm not someone who does a whole lot of visual stuff, but knowing what kills performance is something which really helps me in my day to day job. The theme of the talk was also about making things ugly. Sorry for chuckling when I made the table-cloth example really ugly by turning it to yellow. The third part just blew my mind, it's amazing how powerfull CSS is when it comes to making animations. I probably won't be a CSS-superstar like Estelle, but I really learned a lot how to put this to good use.

Mobile Performance Considerations
This talk really helped me to see what I was doing wrong, I already discovered many of the stuff mentioned myself during a project which needed a lot of optimization. But still, it took me 2 weeks at that time, while I could've just attend this session and learn it in 45 minutes! If you're doing mobile development you really need to watch this talk sometime when you have the chance.

Sencha Touch 2
Ed started the session by saying it was going to be chaos, but it turned out to be a great talk! Ed showed all the stuff Sencha Touch 2 is capable of and even though it was very high level (I'm very comfortable with ST2 myself) it was a very nice recap which got me thinking about the way I am sometimes using it.

The Future of the Mobile Web
Ed was doing a great job to open the second conference day, he mentioned a couple of things I am still struggling with today as being solved recently (so definitely will look into that), and showed us which challenges are ahead. I think he predicted the future in a very truthful way.

User-Centered Design for Mobile – Guerrilla Style!
I really liked this talk as the subject was completely new to me. It was also refreshing to have 2 speakers on the stage doing the talk. Although the subject was not in the line of my day to day job, it was very insightful to see how things in the processes close to me work, and to discover why I get certain demands from my PM. One thing I'd also like to mention is that the design of the slides was really really nice!

Progressive enhancement for Android web apps
This talk was very interesting, when I think of progressive enhancement I think in terms of CSS and Javascript. But it turned out to be an awesome talk about how you enhance a website to an app on Android. I really loved the punch line saying that what Chiu-Ki told us was actually how Phonegap works internally. What I always did for Android was just copy over all the Phonegap stuff and configure my project, but this really gave me insight in how I can bend things to use it for the better. And that is very useful when it comes to creating real apps, in present day you still can't do everything without doing some native stuff.

Future Friendly is being Device Agnostic
I missed this talk on the first day so I was glad I could attend most of it on day 2 of the conference. Joe really has awesome slides and the way he speaks about creating mobile applications really gives me the energy to do an even better job next time. Going through all the technologies was really cool, and using SOA's is definitely the way to go. I can't wait for all the other devices which will adopt mobile technologies. That's what's making my job fun and challenging!

TBA
Although the talk was short it didn't quite matter, there was a soccer match to be played that night! :) But Joe showed exactly where we are going to, people spend a lot of time and money on mobile devices. And to target each and every consumer the best way to go is using SOA's and do the consuming of them in all the great technologies we have available. This talk confirmed the way I look at present day and the future of development myself.

Tools of the PHP Trade
Even though I did a talk on Continuous Integration and the tools involved, it has been a while that I updated myself with the latest developments. So I decided to visit Lorna's tutorial. Lorna did an excellent job in telling the people who just started out how all of the tools work, and she also took the time to give a good answer to the more advanced questions, which is excellent! Even though many of the tools were a recap for me, I learned some new stuff as well like XHProf which is amazing! I'm very satisfied and I returned back to my hotel as a more enriched and confident developer!

Password Storage and Hashing
This talk was extremely useful, Anthony showed us the different types of encrypting passwords and how easy it can be to brute force them. The numbers were real eye-openers and PHP 5.5 will have some awesome features to create ways of securing passwords. I'm looking forward to seeing the full talk, it's the kind of hardcore stuff we developers love to work with.

FirefoxOS - Boot to Gecko
It's too bad I didn't get my actual message across, we're all already mainly web application developers. So the things we do can be ported to an actual device with a minimum of effort. And yes... the API's are nice, expect to have an increasingly lot more data once the WebAPI's are getting standardized (that was actually my second message). But the feedback helps; I concluded that if I do this talk in a PHP setting that I need to focus on the possibilities behind the platform, not the actual platform.
