 Meine Freizeit verbringe ich gerne am Computer. Dort programmiere ich entweder kleine Dinge für mich ([siehe GitHub](https://github.com/michivonah)), wie diese Website, oder hoste neue Software auf meiner Infrastruktur. Ebenfalls gehe ich gerne Spazieren und höre dabei Musik oder Podcasts zu. Zudem bin ich ein grosser Fan des Europa-Park und besuche diesen regelmässig. Um meinen Tag dort optimal zu gestalten, habe ich sogar einen Bot gebaut, welchen mich jeweils per Push-Benachrichtung auf mein Smartphone über die aktuellen Wartezeiten informiert ([hier die Details auf GitHub](https://github.com/michivonah/themepark-alerts)). Ausserdem fliege ich gerne mit meiner Drohne oder mache Fotos mit meinem Smartphone. Und manchmal backe ich auch einen Kuchen.

 I like to spend my free time at the computer. I either code little things for myself ([see GitHub](https://github.com/michivonah)), like this website, or host new software on my infrastructure. I also enjoy going for walks and listening to music or podcasts. I'm also a big fan of Europa-Park and visit it regularly. To optimise my day there, I even built a bot that informs me about the current waiting times via push notification on my smartphone ([here are the details on GitHub](https://github.com/michivonah/themepark-alerts)). I also like to fly my drone or take photos with my smartphone. And sometimes I bake a cake.
