This question has been asked a while ago [1] so I wanted to ask again, what's the best codebase you've worked in or seen? Could be a work codebase, open-source or just your friend's side project.<p>[1] https://news.ycombinator.com/item?id=20556336
The Linux Kernel, by far. Once you understand The Way the Kernel developers writes code, you can understand a lot of code you've never read before because they use the same patterns. I've worked with a lot of open source stuff and none is as neat as the Kernel.
An internal framework for mobile apps that the CTO of a previous company had built. Very simple and very flexible surface that hid a lot of complexity of persistence, offline state syncing and conflict resolution.
