I love reading through a codebase liberally annotated with comments noting ideas and techniques cribbed from blog posts, textbooks, research papers, personal correspondence.
I feel like a lot of that ends up in pull requests instead of codebase comments now. That's not necessarily a bad thing, except that pull requests tend to be locked inside walled gardens while git repos move the history durably and fluidly.
Anyhow. Just something I really enjoy. Thanks to those who do that. Love it. ❤️
