Database version control without pain
Very interesting and clear presentation. Also some nice solutions given, although i think he forgot the solutions to name his patchfiles after source control revision numbers.

Regex clinic
Nice talk, starting from scratch and going to expert in 1 hour. I knew how to write some basic regexes, but after this talk, I knew a lot of features i didn't know about, and learned to to improve efficiency. The only feedback point is, give some quick samples and explenation in the introduction. A friend of mine, sitting next to me, didn't knew about regexes, and then the introduction is vague. He got it by the end of the talk though :)

There is a PHP Library for That!
I liked the description/functionality/example 'drive-by' showing what and how. I've seen some interesting libraries that I didn't knew yet, thanks for that!

You thought Composer couldn’t do that?
I used the basics before this talk. Learning custom repositories are possible, and how to configure them, was a nice addition to that :) Thanks!

Continuous Inspection: Fight back the 7 deadly sins of a developer!
Nice feature set demonstration of Sonor. Also, the deadly sins list, recognisable, I'll keep it in mind :) Thanks!

Scaling your development team
Interesting to see the workflow of a facebook developer. I also like how Phabricator looks like! I'm definitly going to check that out! Sometimes, a few words, I couldn't understand because of the 'speed/accent' being spoken. But i could follow the total talk fine though. I think it's when the speaker gets excited about a topic to explain about, that that can kick in. :) Nevertheless an inspiring talk about large development/operational teams needing to work together. Thanks!

Raffles & Closing
Nice lottery! As a first year visitor, it was unclear to me what numbers where being picked though. At first i was checking out the namecard, but I didn't spot any number on that. Then i thought you needed to register for this lottery, only after that, realizing the ticket was inside the goodiebag (which i probably didn't see when i got it, and at that moment, was in my cars trunk). I didn't mind that much, it was just unclear, and i think that's where a lot of false tickets could come from. (If it was in the keynote, forget this feedback, i missed the first 20 minutes of the keynote, unfortunately). I liked the ending, enthousiasm, and general spirit though! Keep up the good work! I'd love to come back again next year!

Filesystem Abstraction with Flysystem
Nice talk going back to basics with 'What is a filesystem in essence?'. Going into the real problem people don't recognise necessarily, about working with remote filesystems, and providing abstract thinking for it. I loved the fact that you provided a story relating to problems you had to face in the past, which your library provided a solution for. In the future, you could even turn that to the idea of not having to know the remote filesystem while working on most of the application. That you can postpone the decision on a filesystem, while not creating a risk on the project deadline. As pure feedback, you have a stopgap (stopwoordje) 'Basically'. It wasn't really a problem, but just something i noticed. Something I think you also didn't notice, was that you made a nice pun, 'On the fly'. Which i think you could incorporate more consciously in your talk ;-) All and all, I really enjoyed it! Thank you for that :)

Getting Started with Ansible
Nice introduction talk into ansible, the comparison with jargon of other confmgmt-tools like Puppet and Chef made a good comparison to the audience when they already know those tools, to see the differences. Live demo's are always cursed, but these went fine and showed just how the tool worked and 'felt', which i think was a real addition for the audience to 'click' with the information on the slides. The cat-slides were a nice distraction from 'just the information' to keep it light and have humor :)

Introducing Particle\Validator
Nice talk going through existing solutions and explaining why those solutions didn't meet the desired standard. By doing this, Berry made the audience understand the reasons why he made 'yet another' validation library (with good reasons). The roadmap of this project got me excited, and I will definitly look into it to see how it can help me in the future.

Clean Code == Pure Conscience
This talk was a nice overview of how to write clean code. I like how you summarised your 'path' of learning, wanting to share that information with the rest of the world, giving people all the keywords that they should 'google for'. :) Although I think for somebody not familiar with all the topics, this might be an overwhelming flow of 'jargon', and that you're showing people solutions without them really able to match those to certain problems. So I really like the subjects, I just think you're doing too much at a time. Maybe think about breaking it up into several talks where you show examples of problems, and how those solutions can solve that problem. People can relate to those problems more, and you guide them through the subjects by example (a bit like you did with the value objects, but more in-depth. Storify going from this problem to this solution). Also, don't assume people know something ;-) I've noticed that a few times during your talk, even if most people in the audience are familiar with it, please summarise it in a sentence or two. People won't raise their hands to show they don't know something, especially if nobody else does ;-) I hope this feedback helps! I enjoyed the talk!

Building Open Source Communities
Great keynote to spark some though. While I do not fully agree on all points made, It does encourage placing yourself in the person on the other side of the internet (the contributors). Huge +1 on trying to get rid of ego. And thanks for making me rethink about open source licenses.

Making Embedded Domain-Specific Languages a Practical Reality
Really liked the different look on programming languages from the developer perspective, by trying to better error messages. The talk to me was a bit theoretical, which required me to pay full attention the whole time. One of the reasons for that, was me not being familiar with the language and concepts. Even though, the speaker did try to make the concepts clear for everybody. Big plus for that! A point of improval would be to add some more 'breaks', like a quick summary of few extra jokes in between. Other then that, excellent talk!

Bees & Sensors
I loved watching this talk. It really shows you how technology can have impact on the real world, and our understanding of it. I learned a lot about bees ;-) I really liked the excitement of the speaker, it was really contagious, and I could feel that through the room. It worked both ways I think, and amplified both the speaker and the audience's enthusiasm.

Abusing Phones to Make the Internet of Things
Awesome keynote showing how the world will connect, and how thinking outside the box can be extremely fun. Very inspiring! I loved how browsers will play a role, and with which you can make full use of all the sensors in your phone, something that almost everyone carries.

Introduction to Angular using EcmaScript 6
Great tutorial! I learned a lot of new stuff. I also love the URLs in between, for when you want to dive deeper into the subject (later on). A point of feedback, try to use less shortcuts, or leave a bit more time between switching different files. You did leave files open when helping people, so it wasn't a real problem, but when you're typing along, it can be just a bit too fast :)
