Upgrade at GeeCON 2022Coding Dojo exploring Property Based Testing
A local Coding Dojo run together with my friend Paul Rohorzka with an exercise focusing on finding properties of a geometric problem as part of a Property Based Testing approach. (Code)
Coding Dojo @ Softwerkskammer Vienna, Vienna.

Pre-Conference Hackathon
To warm up for the main conference, I facilitated a pre-conference evening event, a challenge to find a solution for a specific problem provided by Trayport, the main sponsor. Unlike classic Coding Dojos, this hackathon did focus on speed rather than learning. Still, if your solution did not have tests and did not work in the end, you did not win the challenge.
