Bit unfair of someone to give a 1 star review with no comment. I'd rate this 3-4 stars but I want to balance some negativity and help out.
Your topic is super important and I liked the way you were passionate about it. The laugh exercise at the start was fun audience involvement at the end of a day of conference. You're presenting in what I guess is a second language and at times it was hard to understand - if you slowed down talking a bit I think it'd be easier. The sociology research was super interesting - I'd have liked more time on that and less on SBF (because it's far easier for us to do wrong without realising it compared to true criminality). Good answers to questions. Well done and do this more!
Really nice talk about all the things that can go wrong with other languages or countries. I gained some new insights
An Ideal overview of this topic and well demonstrated with a live demo. Would have been interesting to see an actual comparison with memory values, especially from the Doctrine perspective.
Nice talk about why contributing to open source is something you (or your company) should do, especially when you use open source projects on a daily basis. It inspired me to talk to my team and manager about contributing to open source.
Too fast and quite chaotic
Nice talk with tips about where to start with a legacy project. And when is it useful to refactor code. Useful for me in my day-to-day work.
Nice and good explanation of generators and iterators. Would loved to see the actual numbers that proof the improvements.
