My favorite static site generator, Spacebook, wouldn't build any of my websites ever since I got an M1 Mac with the new Apple chip. I did some digging; it took a couple of weeks of occasional work in my free time, but eventually I diagnosed where the problem was. As soon as I fixed it, I issued a pull request with a fix to the project.
I've benefited so much from that software over the years, that it's good to give back and contribute to open source.
