"Writer's Workshop & The Work of Making Things: Patterns, Poetry" by Richard P. Gabriel

If you are a programmer, attending a writer’s workshop may not be an event on your list of things to do, as you probably do not consider yourself a writer. And yet, if you are a developer on a widely used piece of software, the consequences of what you write may be seen by more people than read the material of all but the most popular of authors. Furthermore, despite all efforts to quantify and qualify software development as a branch of engineering, it remains a creative act, and the code of the best developers is similar to poetry. It reads like a great sonnet, with a rhythm and flow that impresses and teaches you.
