Joa Ebert


Joa Ebert is a non-blocking lock-free greedy coloring humanoid, specializing in technology hacks of the metaverse.

Started programming at the age of 8 and a FutureSplash developer since 96, Joa continuously honed his skills in founding and failing startups. Since he spent more than 71.4% of his lifetime as a coder he came to the conclusion that technology and writing code is a mess but is stuck in an infinite recursion until the universe stack overflows.

With an interest in the deep understanding of things, he (tries to) works on virtual machines and programming languages in his spare time. Sometimes he is pursuing the mastery of puff pastry.

Joa co-founded defrac in 2013 and has been working 169 hours a week ever since.


Improved Technology

While Joa has been struggling with the performance of the Flash Platform he developed Apparat - a framework to optimize and analyze Flash content. A simple idea developed into a complex project with the ambitious goal of an open Flash Player implementation.

Follow Joa on his journey and learn how to use Apparat in your daily workflow. He will illustrate the polyglott implementation of JITB; the open source Flash Player written in Java and Scala.

We will also have a look at how to hack Apparat and use it for WebGL development.
