This document provides tongue-in-cheek advice on how to behave like a "security jerk" as a developer, sysadmin, or end user. It suggests storing passwords in plain text, requiring outdated library versions, inventing one's own cryptographic algorithms, disabling security features like SELINUX, clicking on links without caution, and pasting passwords into pastebins. The document links to a previous edition that provides similar mock advice and links to a website with security-related content.
