Dutch PHP Conference 2015
25 - 27 Jun 2015 at RAI Amsterdam

Finally, an introduction to Event Sourcing that I understood and was able to follow. Good attitude from the speaker too, he was very friendly and approachable after the talk.

Great presentation skills and also really good, well thought out content. One of the best sessions I have seen at this conference.

Good talk about defensive programming. It was a bit basic, but that's to be expected given it was a beginner talk ;)

I think it's nice that you looked forward to PHP 7 but also gave some solutions for the mean time.

Applying the SOLID principles to your code will make it easier to cope with change. This was (unintentionally) demonstrated by Scato when he not only had to switch rooms but also had to use a different laptop in the last minute.

While most people will know the SOLID principles by now, Scato demonstrated them with some real life examples, while refactoring the application (live) at the same time. This made the talk interesting, not just for people who are new to the SOLID principles.

A bit disappointing, had expected a great talk but the talk in general was kind of 'down', sadly told, sometimes with humor but most of the time on a negative side... But the general message should be clear: respect people and especially appreciate the work that some people do, and don't react in a negative way on things you would have done otherwise or features you are missing in the software. You can give advice on what to do better or what to add, and on the same time give the creator a good feeling...it should not all be negative.

Nice talk, I enjoyed it very much.

One improvement: Stick to the most important subject (State!) and don't mention stuff that doesn't matter like PhpStorm tricks or JavaScript code. The checkout code was more than clear to me.

Hope to see more talks from you!

A good talk from some points of view, but not an excellent one. Or maybe I didn't find it practical enough. For example - ok, you can use an array, but why and when it is useful? What about performance and memory?

Also, I hoped to hear about PostgreSQL JSON output, and the ability to write procedures in JavaScript.

A very good explanation for people who don't know network protocols, or their latest versions. I had the opportunity to hear about several practical hints.

I'm not sure if this talk was for beginners or for advanced users. Beginners (if any) probably had a hard time while trying to understand the big amount of staff mentioned during the talk. And advanced users want to see something more: examples, benchmarks, etc.

For example: Sys Schema. I'm happy to hear that it exists, but what does it? Also, it is built upon information_schema and performance_schema. But then, I cannot accept statements like "its overhead is 2-5%", this is simply impossible, because p_s can be MUCH slower than 5%, and i_s acquires a lot of metadata locks.

I was really excited when I entered the room to attend the talk, but... I'm sorry to say that I expected much more.

Great opening keynote. A wave of enthusiasm that got everyone awake.
