The above image is the drawings that I fed to Claude Code and the resulting working watchface for a Pebble Watch that was produced after 5 sessions (each one lasting until i burned through my tokens which was about 20 minutes a session).
People are bad talking “vibe coding”, but quite honestly “agentic coding” is so empowering! Read on for more details of the adventure!
I have another post about the wild flowers at the magical Ermita de San Antonio but have begun noticing other wildflowers that are at higher elevations or maybe just have not yet seen them there, so I will start a new reference note to the flowers I discover on my walks around Cercedilla.
Today, the first day of Spring of 2026, was unfortunately cloudy and raining all day, but fortunately this afternoon there was a pause in the rain and we were able to take a walk to the Ermita de San Antonio. Possibly due to the sky being grey and our attention not bound to the horizon, we noticed that all the rocks are cover in splotches of all sorts of different colors. My wife commented that it was because the rocks in the the Sierra around Madrid have a lot of granite (correct) and I said I thought that it was due to lichen (also correct). Read on for what I learned once we got home and I began investigating!
That was exciting! Yesterday morning I was having saturday morning coffee in bed doing a bit of prompt driven development to add weather predictions to my Remarkable sleep screen when suddenly weird things started happing on Ersa, a Raspberry Pi 4 Model B that hosts everything in my house including this blog. By weird I mean I was trying to create a new file but said it was a read only file system. I figured I had run out of space, but was not the case, so I opted for a “windows” solution: reboot. And that was all she wrote and Ersa did not come backup. The picture above is the open heart intervention on Ersa trying to figure out what was going on. Read on for the frantic recovery actions and a incident postmortem retrospective to ensure this learning experience leads to improvements!

When I started the field note series I would not have imagined that one of the posts would be about “wind” but I have had an intense last 7 days thanks to the wind in Cercedilla and not for the first time so I thought it is a legitimate post from the field.
Last Monday (February 16th), as we can witness in the picture above, there were burst of winds (“Racha”) up tp 91 km/h (56 mph). I got a call from a kind neighbor (thanks Fernando!) to let me know a tree from my property had fallen and was resting on the communities telecommunication cables (fortunately not electric):
Read on for all the fun that ensued and for last years wind problems as well!
