Most my fun has been on the non-tech side. To get a break from the computer last year, I ran the length of Japan (around 3,447 km). And now I've been helping my partner edit the videos and stick them on YouTube:

On the tech side: I've spent the past few months working on little projects mostly coded via LLMs. Used it to build my own little AI agent in python attempting to keep it stdlib-only, and a little blog engine with MFA. Things I would never have previously been able to do as a sysadmin/infrastructure but not developer. It's been an interesting learning experience, but have spent months not getting anything to a fit state to share with the world.
