I follow the folks over at 100 rabbits (https://100r.co) and I think they’ve sort of developed yak shaving into a lifestyle.
I don’t want to go too far into it cause the website is a treasure trove and exciting to explore on your own but if you follow some of their latest stuff, they’ve built a stack based virtual machine, and a whole set of software around it and it truly feels like they are just exploring every avenue that interests them without rushing themselves. Truly the embodiment of my grow a beard and learn Haskell dreams.
