At this time of the year we always bring something special, when it's cold outside it'll be extra warm indoors! No excuses for this year! It will be fun, you can win stuff and you'll even learn something!

Your organizers; Chris, Jeroen and Johannes will close the year with a few awesome talks! Level23 ( will fully sponsor(thanks) this evening, so there will be enough finger-food and drinks for everybody. We'll have some music if you would like to dance a bit.

The Awesome Super Secret Talk - Johannes

Johannes will kick-off with something interesting, his mind is full of awesomeness. It'll be a soft-talk, check-in later for updates, we'll let you know in the comments.

Template Bridge - Jeroen

Have you ever been stuck in a frameworks (outdated) template engine you must use in your day-to-day job? Where you rather start using something fresh you really like? You would love to have a choice for twig, markdown or something else! The thing you run into all the time that it is a real PITA or (near) impossible because you'll need to replace all the existing template files. Who's gonna pay for that kind of change?

I'll share a working concept where you implement a Template Bridge with some simple(or advanced) rules and start using whatever you like. You can also mix template engines, for instance; markdown, twig, yaml, javascript, plain text and a fallback on the original engine. This way you can start working and only migrate files you are working on and leave other files untouched. It'll be awesome and will save you a lot of time.

The talk will be technical, we'll cover some existing implementations and how you could kick-off for your project.

Happy 2018 - Chris

"doe maar gewoon, dan doe je gek genoeg / laat je niet gek maken in 2018"

I'll share some insights in my life as developer, entrepreneur and dad. Choices I made over the last years and what it changed!

The talk will be in Dutch and non-tech but fun to watch and end the year with.
