I'm a huge fan of his guides for their readability and straightforward delivery. I'm always on the lookout for more authors like him - have you come across any similar authors?

Recently came across this nice guide on Git pull request workflow: https://github.com/susam/gitpr

All the important stuff is in the first 4 pages. I have the PDF version on my desktop. Also printed pages 3 and 4 and stuck it to my cubicle wall.

This got me started with socket programming back in 2000 or whenever, and I still refer to it occasionally. :D
