The Happy Hacker offers you the secrets and tools to become an Überhacker and Cyberwarrior, and even how to build a railgun. But who is this Happy Hacker? Though other folks are now involved with the website, Carolyn P. Meinel is the primary face of The Happy Hacker. She is a long-time computer hacker, going back to getting unapproved access to the PLATO system (previously). She started Happy Hacker because "all sorts of guys were begging me, 'teach me how to hack'." Her webpage gained attention, getting mentioned in The Happy Mutant Handbook, and being invited to speak at Defcon. But there are people who doubt her credentials, and others who are a lot more harsh. Regardless of the backlash, and the appearance that the peak of The Happy Hacker has passed, her articles are still being published.
