La conférence
Paradoxes and theorems every developer should knowWhat do german tanks, your birthday and quantum physics have to do with our daily development work? It turns out, quite a lot! During this presentation, I will explain a series of mathematical theorems and paradoxes that we encounter every day during development, but we often fail to recognize. By using these theorems, we can create better code, find more secure and efficient solutions to our problems, and it even helps you out communicating with clients and project owners. |
You are the author of a book on PHP’s SPL, what did you learn from that experience?
Writing a book is hard but grateful work. Knowing things and actually putting it on paper is not easy, just like presenting a talk about a subject. You need to completely understand your subject in order to be able explain it to others. I was always afraid that I added things in the book that didn’t were right but fortunately there was a team of proof-readers and technical experts who have found most of my mistakes 🙂
Besides the SPL book, I’ve written a few more books about the Symfony project, and even a book about starting with Python from a PHP developer’s perspective which are available on leanpub.
You created the Transphpile project, a PHP 7 to 5.6 transpiler. Why did you start this project? What did you learn along the way?
The project started out as a fun project on the PHP benelux conference a year ago. Transpiling code is quite common in other languages like javascript, but nothing of the same has been done with PHP. We took a library that parses PHP into an Abstract Syntax Tree (AST) so we could modify it in any we we liked. We took the (main) features from PHP 7 and tried to see if we can create a « php5 » alternative for them. It turns out that this was by itself a bit harder than originally expected, but we managed to implement many php7 features. Since the project started out as mere fun and experimental, we never continued with implementing everything and it should not be used in real situations, but it might be a good read for everybody who is interested in working with AST’s.
Can you tell us more about the PHP community in the netherlands?
The PHP community in the Netherlands is the most thriving one I’ve ever saw. We probably have over 20 different usergroups for PHP alone, and considering how small the Netherlands is, this is a large number. Every week there is probably a usergroup in a nearby area. This causes problems too: there is as always a speaker shortage, but on the other hand, it gives beginners a good platform to start speaking and rehearsing their talks.
