I know I posted already that I passed the B1 certification, but I wrote a short blog post about my journey to the exam (and beyond), nonetheless 😁✌️

My Journey to Passing the B1 Certification for Italian as a Foreign Language
Back in October, I took the official Italian B1 exam from Università Roma Tre. After waiting several weeks, the results arrived — and I passed with 90/100.

Today's #training was my usual #Friday #LongRun - tried to stay on pace and not to go off too fast.

Sono felice di condividere che ho superato la certificazione di italiano B1 dell’Università Roma Tre.
È stato un percorso intenso e molto formativo.
Questo risultato mi dà nuova motivazione per continuare a migliorare, giorno dopo giorno.

Today's #training (first #winter #maintenance #run) was a #progressive run from 5:45 to 5:05 in steps of two km. Managed to hold the pace also uphill 😎✌️

Today's #race was the last one for 2025. Took it easy and just enjoyed it - even the stairs up to the finish line. Bonus: My wife and daughter joined me to cheer me up!

During today's #training, I smashed every one of the 8 #intervals (target pace 4:55/km) 😎.

The rest of the week is free before Saturday's #race, which will conclude this year's running season.

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.

@microsoft.com just introduced Custom #Agents for #dorNET #Developers: C# Expert & WinForms Expert

I had a first look on the code of the C# agent - my rating: comprehensive starting point that is ready to be used. Go give it a try - so will I!

Just had a very intense session with #ChatGPT.

Several quirks occurred:
- saying to perform a task with the next message without actually doing it
- failing to get markdown formatting right
- repeating the same questions over and over again

At some point, I just had to stop using it.

Very interesting article on Spec-Driven Development in the #AI age.

While reading, I was able to relate to my personal experience in many ways. #SDD in AI is in its infancy, and it will be interesting to see its evolution in the future.

Today's #training with #Runna were #HillRepeats (15x 60s hard uphill, 30s rest, easy jog back down) - with stiff glutes from yesterday's #strength #workout

Did some extra stretching afterwards.
