An image showing a collection of playful, mock "Wanted" and "Have You Seen This Dog?" posters pinned to a dark bulletin board. The posters feature humorous text and drawings, including a "Wanted" poster for answering a beginner question patiently and another for a "big-ish reward" with a smiley face. The central poster shows a photo of a fluffy brown dog with text asking to let "Rosa know you saw her dog."

Another thing I'm fascinated about lately: Baarle-Hertog and Baarle-Nassau 🤣 en.wikipedia.org/wiki/Baarle-... en.wikipedia.org/wiki/Baarle-... "The border's complexity results from a number of medieval treaties, agreements, land-swaps and sales between the Lords of Breda and the Dukes of Brabant."

Attended a great presentation on Tidewave yesterday at @madridrb.com . Mochi was particularly interested, as tools like Tidewave make her job of doing my job much easier! 🐾

This was a pretty good year in sport/running for me 🎉🏃🏻‍♀️ the first time I followed a training plan to get faster! I really embraced being uncomfortable and loved the discipline of it 💪🏻🥰 PBed half marathon but didn't achieve my other fitness goals: 2 strict pull-ups and full front splits. For 2026!

My self-gift for Christmas this year was the clear/blank keyboard for my framework laptop frame.work/es/en/produc... I got the whole input kit because I also switched to ANSI from ISO. It looks so cool! I'm not as good at typing on it as in a regular labeled keyboard but close enough

I had a small running motivation crisis this year when I just couldn't mentally run more than 8 or 9 kms together, coming from an injury and basically no long runs in 2024. This has made the end of the year rather thrilling for me 🤣 (as thrilling as totally arbitrary goals go, that is)

Special thanks to @julianrubisch.at and a few other folks whose bsky handles I don't know, for their patience talking to me in German, and for the super interesting conversations! 🥰 In addition to that, Mochi did a lot of networking and got a bunch of attention, which she enjoys very much 🤣

I have the same setup with a standing desk, and the socket strip (obviously "ladrón" or "alargadera" is a much better term 🤣) has this cord. TBH I'm not a super tall person so it's not like it needs to extend a lot 😅😅

Well, I’ve come a long way since 2018! 4’22’’ / km! I didn’t think I’d be able to do below 4’30’’ in 6,2km 😊 obviously the parts downhill helped a lot 🤣 but there were a couple of tough uphill parts so… I’ll take it

One day, I'll write a guide about how to fly with your small pet (< 8kg) across Europe, applying to the EU + Switzerland and Norway, but not the UK. It's the question I get asked the most when I travel with Mochi and it took some time and some mistakes to figure out all the quirks
