I've been using Zellij for 2 days, and I love it so much, wow. This adds to my subjective impression that all cool things these days are written in Rust 😆 Also, instant-GitHub-sponsor from me 🙇🏻♀️

Every time I come to Belgium 🇧🇪 I end up with some kind of annual pass that's just too great a value to overlook, even if I'm here for roughly a month, and that feeds into my dream of moving here on a permanent basis 🥹😆 So far, I've had spin/HIIT classes, museums, public bicycles, and now trains

Today I ran Brussels half marathon and it was 21.1km of pure joy! 🥰 My favourite ever. I took it easier as it was hilly and just wanted to enjoy one of my favorite cities in the world. It was awesome. Perfect weather (not so much for the full marathon, as the rain started later) and gorgeous course

I'm moving back to Android after ~6 years on iOS. The reason is that I can't stand iOS 26. I tried, but I dislike it so much. The only thing preventing me from moving was my Apple Watch, which, after 3 years, was still working well, but its screen conveniently died last week 😅🤷🏻♀️

The half marathon finally happened today, under heavy rain for the most part, and I ran it after having arrived the previous evening from Whistler, BC, Canada, so after ~22h or so of travel 😆 But the training really paid off! PB at 1:48:44! Not quite the 1h45 I was aiming for, but I'm super happy!
I just completed week 16/18 of my current half-marathon training. It's the first time I do a training focused on getting faster and it's been really hard for me. But I managed to follow it to the t, even during the Ruby Triathlon. Doing the speed workouts (2 per week) while travelling was tough!

Well I just discovered I’ve been using an invented German word since forever, “gleichweis”, to mean “likewise”, and that multiple people have invented the same word and used it, some also for years: www.reddit.com/r/German/com...

Obviously, I already have a ticket. Plus, I checked that the hotel is dog-friendly 🥹🐕 Does this mean I need to start finding a toga in XXXXXS and 4-leg size?

More museums in Madrid now allow dogs (with no special restrictions, just any well-behaved dog can enter). One I just found about: Museo del Ferrocarril (train museum), a very cool one 🚋🚂🚆❤️ They didn't allow them in the past, so I'm happy to see that changing! 🥹
