π₯ Seven Ineffective Coding Habits of Many Programmers by Kevlin Henney (text summary). I’m surprised I haven’t published it before. A great conference talk about how humans read code, and so how to make your code a bit easier to read and understand.
This talk is what inspired me to create flake8-length that keeps line length short without compromising readability of messages, and flake8-comments that tries to catch useless comments.
