Code is written for people: Knuth, Guido and the Hitchhiker's Guide on readability

Donald Knuth explains in two conversations why he writes programs as literature through literate programming, Guido van Rossum describes programs as recipes written for two audiences and digs into code readability, and The Hitchhiker's Guide to Python devotes its core chapters to writing and reading great code. Treating the human reader as the main audience changes how programmers name, structure and explain their work, and makes code easier to maintain.
