This issue of Hacker Monthly features two articles on Bitcoin — one is an informative piece on understanding Bitcoin, and the other is a technical overview of how to launder Bitcoin (entertainment purposes only).  In addition, you’ll find an array of fun and useful articles on programming and startups such as “Things I Wish Someone Had Told Me When I Was Learning How To Code,” and “An Engineer’s Emergency Kit Business Card.”  Also included in this issue are the following additional stories:

• A Testament to X11 Backwards Compatibility
• An Engineer’s Guide to Stock Options
• Debugging a Live Saturn V
• On Hacking MicroSD Cards
• Why I Wrote PGP

Every month, we select from the top voted articles on Hacker News and curate them in magazine format. The submission guidelines for Hacker Monthly state that content can be “anything that gratifies one’s intellectual curiosity.”
