Evolution and history of 35 years of hardcore/gabber music [XXL edition]
Elger "Stitch" Jonker

This talk is a "no clip" deep dive through a genre of music. We'll start in 1990 and discover the genre as it was discovered by its creators. While traveling through time we'll try to answer the question: what is hardcore?
There will clips and mixes of revolutions and sub-genres. We'll learn how it's made and how to win the loudness war. Hardcore spawned a youth culture with lasting international adoption. From art to cheese, we'll cover it all. We'll learn the dance and end with a live set.

How we made the Netherlands more secure and accessible using transparency
Elger "Stitch" Jonker

It started with a simple idea in 2016: make the state of security of our government transparent/public. The simple idea has become national government policy. Using transparency we've helped fix tons of security issues, reduce costs and increased control on IT. This year we've rolled out in Belgium and started measuring accessibility of websites in the same fashion. Learn how we've achieved extreme impact with a minimal budget and keep on doing so. Security and accessibility must be commodities.

Yearn for a better future
