The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say.

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better architecture long-term vision, more features and no license problems. It's called : Workout.cool (https://workout.cool). What it offers: 100% open-source, MIT-licensed - 1200+ exercises (with videos, attributes, translations) - Progress tracking - Multilingual-ready - Self-hostable I'm not doing this for money. I'm doing it because I believe in open fitness tools, and I’ve been passionate about strength training for 15+ years. If this resonates with you, feel free to: - Star the repo - Share with fitness/tech friends - Suggest features - Contribute code/design/docs Together, we can build the open-source fitness platform we all wanted to easily build a workout routine and get in shape Website: https://workout.cool GitHub: https://github.com/Snouzy/workout-cool

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!
