Stress-Free Deployment
I like the constant references to real-world examples, and how Rob himself uses the tools for deployment. Interaction with audience was good, quality responses were given to questions posed.

Simplify the access to the cloud computing services with Zend_Cloud
This was interesting to see how applications can easily be extended to make use of the available public cloud services, and how Zend Framework managed to abstract these services for easy implementation. A very nice demo, which showed Amazon's EC2 in interaction with ZF's Cloud extensions.

Mastering Namespaces
Spot on. All aspects of namespaces were covered, and explained well. Included with examples & references, I really learned a lot about a feature within PHP that is (at date) hardly used, but is needed in the future. For feedback; keep the intro about yourself a little shorter. While important, namespaces are more so. :-)

HipHop For PHP
Always interesting to hear a Facebooker speak, it's always with passion and interest. This talk was no different. Hearing about these large-scale deployments and difficulties they face, always presents nice uses cases which he managed to use to keep the audience interested.

Varnish, the high performance valhalla?
I liked the reference to the client case, and real-life config/code examples on how to implement this further.

PHP Through The Eyes Of A Hoster
A presentation that, from a hoster POV, covers just about every aspect. It's kind of awareness that is needed to educate PHP developers of their impact on server-side configurations. The presenter made it a very informal presentation (small room, all in Dutch) with good audience interaction.

PHP in the dark
Very informative. I had forking/daemonizing experience, but this talk explained the fine-grained details I kept missing. A lot of information about forking etc. is scattered over the internet, this is a very nice summary. The speaker showed knowledge in his area and was calm & informative throughout the talk. /me like!

Building scalable Web on Open Source technologies
All points were valid, but the speaker was mumbling and speaking very softly. Shame, could have been a lot more motivating.

Linux Containers
Good overview, at times the room knew more than the presenter :) Still looks a bit like beta to me.

Single sign-on with Kerberos and LDAP
Very deep techdive into kerberos, ldap was mostly skipped. Clean demo with quick debugging. Wouter's debian knowledge amazes every time :)

Puppet for dummies
This was a very good talk: you gave a thourough introduction to Puppet, explained the different components and the workings. The live demo (without problems!) showed it all very well. As a positive comment: you may want to emphasize the initial configuration of puppet (master/agent) a bit more, as it all seemed to go too smoothly on your test set-up. :-)

Powering Your Website with Realtime Data
The concept and reasoning behind XMPP are interesting, and your (recorded) demo's definitely showed this. For future talks: try to be more spontaneous. It's ok to prepare talks, but don't just read the text from a laptop. Interact with your audience. You obviously know a lot about XMPP as the Q&A showed afterwards, try to show some of that passion in your presentation by talking more "loosely" about the subject. :-)

Estimation or, “How to Dig you own Grave”
Obviously you are a well experienced speaker, you have a way to talk while keeping you audience motivated. Great points in the presentation, I learned a lot!

VIM + *nix Toolchain == PHP IDE
Holy crap, so much new stuff! Shame you ran out of time near the end and had to run over it, but very interresting stuff.

Doctrine 2: An Introduction
At times a bit hard to follow due to the speed of your voice. But you gave the talk with great motivation and gave compelling arguments to use ORM. I'll give it a go based on your talk. :-)

Designing MongoDB schemas
It's frustrating to be on the end where EAV and 6NF have been discussed in detail, only to hear that MongoDB is the perfect solution for those use cases. :-) I've thoroughly enjoyed the talk and learned a lot, I liked to practical examples and pitfalls you mentioned and the general overview on MongoDB with extra slides on the scaling/sharding part. Very good presentation on a very interesting topic!

Choosing the right tool for the job. When (not) to invent the wheel
I'm a numbers-guy, so I appreciated the pricing comparisons and charts you used to prove a point. The idea of playing 2 "stereotype" developers against each other is also interesting. Since it's a rather die-hard PHP crowd, I would change parts of the presentation to be more "to the point" and as already stated by the other commenters, to include more real-world examples.

“Small Data” Machine Learning
You managed to explain complex formulas on screen in understandable terms. It was an interesting problem and solution you presented, very enjoyable!

Symfony Content Management Framework
I think I had the wrong expectations for this talk, so my rating may be ill-placed. Your talk presented a thourough overview of the CMF, but perhaps lacked some proper code examples (after all, we're developers, this was more of a GUI runthrough). How to extend it, how to implement, ... If you're giving this talk again, please consider updating it with a more developer hands-on approach, instead of the user-oriented approach. :)

Process any amounts of data. Any time
I enjoyed the talk, the clear code examples showed a good reference to before/after scenarios. I'm sure you already know this, but you speak very quickly - it may be usefull to breath once in a while in between slides. :-) I'd love to see a follow-up talk with more code examples and perhaps some benchmarking (file_get_contents() vs. fread() in memory/CPU consumption).

Gearman and ZeroMQ, two different animals
This was a pretty detailed talk about Gearman vs. ZeroMQ. The good build-up of first explaining the key terms and then matching them together payed off. Very informative! As was already mentioned above, more code examples would be appreciated (perhaps real-life ones from ZeroMQ as used in a project instead of the theoretical examples from the site).

Scaling your development team
You're obviously an experienced speaker, it shows in the fluency of your talk the way the presentation builds up (and the presentation-design-team surely helped, I'm sure :)). However, I was expecting a different kind of talk based on the title. This was a very good guideline on the tools used to scale, but it didn't really show the painpoints in scaling a developer team, what went wrong and what went right. At what point did you first start splitting teams? When did the need for self-written internal tools exceed the availability of tools out there? Nonetheless, this was informative and funny, I'd love to see more of these kind of talks. :-)

Javascript fundamentals for PHP developers
I've had the pleasure of seeing the talk evolve and must say I was impressed with how little Javascript I actually knew (despite my thoughts on it). You've made a clear comparison between PHP and Javascript, you were understandable and took your time to explain complex matters such as SEFP and Closures. For a next talk, it may be worth checking into if you can highlight the "scope" in Javascript a bit more clearly (highlighted boxes around scope areas?) to show easily where closures start and end. Overall: nice one Chris!

Ruby for PHP developers
Hi Joren, You've made a very good effort on covering nearly all grounds, from syntax to classes, from dependency management and unit testing, ... a very solid base. For future talks, I would advice talking your time to sit next a PHP guy and have a side-by-side comparison (especially if it's a "ruby for PHP" talk) to show where the matches and differences are. I'm thinking Gemfile vs. Composer, unit testing comparisons, ... You were understandable, you didn't appear nervous and took your time to explain things (instead of rushing through it). :-)

Introduction to Docker
Great preparations, everyone was up-and-running in 5-10 minutes. Kudos to that, as a lot of other tutorials have spent 1h+ on prep. Your vagrant boxes were a good example of how it should be done. As for the content: for me, it was just perfect! I was fast-paced, highly technical, explained enough of the gotcha's to protect and left enough questions open for me to investigate further afterwards. 3 hours well spent on learning docker!

Low-Level PHP, Getting Things done with Go
I liked the presentation, it covered a practical scenario with code examples and comparisons to the PHP world. I'll remember the quote "Go is like programming in PHP4" as a reference to more functional programming (especially since I came from the PHP4 world). Clear talk, good instructions. Go is still on my todo-list. Thanks for taking the time to put together a presentation and share your code!

Getting Started with Continuous Integration
I was expecting a talk about how to tie all those tools (phpunit, codesniffer, mess detector, phing, ... ) together, make a strategy for actual CI and how to implement it. Instead, it gave the building blocks with the solution still to be built. Maybe I misread the introduction or was interpreting the title differently. It wasn't for me, but that isn't to say it was a bad talk. For someone unknown to those tools, it was a really good introduction.

Advanced package development
I don't maintain PHP packages, so for me everything you described was fairly new. That said, I learned a lot. The obvious hints are worth repeating (from the PHP checklist) and the tips on Composer and the helpful tools like construct and studio gave the talk meaningful value to me. I can imagine for a seasoned PHP developer there may not be a lot of new content in this talk for them, but if that's not your target audience - and you're aiming for starting/intermediate PHP developers - this is a very well designed talk with plenty of useful content and tips.

Kunstmaan bundles for Symfony 2
The dangers of talks like these is that they may end up looking like a sales pitch. :-) It's not always easy to find the balance, but I think you managed to do OK. The talk was very well designed, which is always pleasing to the eye. It gave a thorough overview of the features and tools included in the Kunstmaan bundles, they obviously offer a very nice CLI client that help speed things up. I did not have a use for it myself, but I do appreciate the value it brings. The many questions that were asked during and after the talk prove that there is value in both the bundles and the presentation, for getting it known. Ps; live coding is always dangerous, if I can offer any kind of advice, it's to prepare the live coding as much as possible and have a back-up plan (screencast). :-)

Taking Care of Backups With Laravel
Beautifully designed slides, excellent topic and a good speaker. You come of as a very relaxed speaker with good knowledge of PHP. Briefly explaining the different open source packages was also a nice touch, as it was a good 5-minute intro that the audience can further investigate on its own.

Embrace Chatops, Stop Installing Deployment Software
Really nicely designed slides for a fun topic! A good overview of the technologies you can use and how to set it up. If you want to give the talk again, I would really like to see more examples of typing everything together: show some more real life code perhaps, of what triggers/code you use? The current examples gave enough of a tease to make me want to look into it!

Modern Frontend UI with Vue.JS
I loved this talk! The speaker has a great passion for its project and explained (highly technical) concepts clearly, so I as a non-developer can easily understand it. Great flow to the talk with the different paths VueJS is taking and how the reasoning is behind projects like vuex.

Making the Most Out of MySQL
Loved it! Clear examples for the differences between 5.6 and 5.7, the pitfalls and new powerful features you can use. Nicely explained difference between stored vs virtual columns too, it really stuck with me!

Curing The Common Loop (With Collection Pipelines)
Loved the live coding examples where you walked through the thinking process of refactoring "ugly loops", it really made the examples on the slides you showed earlier much easier to understand. Very nice work!
