Coding Fun: Exceptions for Control Flow
To start the day, I proposed a Coding Fun session: Only use exceptions for control flow. This is an anti pattern but it made the participants think outside their usual ways. (Slides)

Coding Fun: Named by Dices
To conclude a great day, I ran another Coding Fun session. This time we named everything but test methods using random dices. (Slides, Dice Namer application)

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.
