I’ve finished the Main Composition module of the Lead Essentials course and reached the White Belt (4th stripe). This one will have a big impact on how I approach app composition, modularization and testing.

Today I went out for the last #run before the #holidays (because I have some medical treatments which don't allow me to go out for a run in the next two weeks).

Woke up and learned my #Claude account got banned without any further notice. That comes only after trying to connect #ClaudeCode to some of my #GitHub repos, where I had some problems. That sucks. Waiting for the result of my appeal. 🤯🤬😖

Just finished planning and registering my 2026 #running season's main #races:

- Zürich Half Marathon (2026-04-12)
- Greifenseelauf (2026-09-19)
- Rome Half Marathon (2026-10-18)

My goal is to finish all three of them under 2 hours at least, but target time is 1:50h.
