What started as “let’s add some OpenTelemetry to a Python game” for my talk…
…turned into a microservice refactor, clear service boundaries, and CI/CD everywhere.
AI-assisted dev speed was wild. Dashboards, traces & metrics weren’t just visibility - they fueled the refactoring. Massive learnings 🤯

Wir sehen bei der kleinen (8) große Fortschritte, wenn Couchsurfer da sind, kann sie zwar nicht reden aber verstehen.
Alles mit Maß und Ziel, ich kanns auch mit Sport übertreiben, streaks, etc. haben wir am Anfang gekonnt ausgeklammert und es war nur auf den Eltern Geräten installiert

So the night train adventure starts...
Sidenote: that's what you get for traveling by night train to most conferences -> kids who also want to ride the night train. To be honest I am really looking forward to this adventure with the kids.

Some tools force you to learn a complicated API and require constant maintenance.
Other tools... just work, and that's why it's easy to overlook them.
@openfeature.dev is one of those tools.
Do I use it daily? Yes.
Do I ever have to think about it? No.

That was the whole trip from the karnischen Höhenweg we did.
We had to skip the last down climb. My knee did not want to do that anymore.
