"Hacker Monthly is a print magazine version of Hacker News — a social news website wildly popular among programmers and startup founders. The submission guidelines state that content can be “anything that gratifies one’s intellectual curiosity.” Every month, we select from the top voted articles on Hacker News and print them in magazine format."
