The “Chad” bug
This is remarkable. I always find it interesting when bugs like this occur.<p>It reminds me of a hackathon I attended where a food ordering startup (I forget the name, but they were chosen to feed us dinner that night) had a similar bug, which baffled me beyond belief. Without going into crazy detail about my password, it typically follows a certain pattern but is never the same across websites. For some reason, the website kept saying my password was invalid. It met all the password requirements that the website asked for (length, capital letter, etc.).<p>I forget the exact details, but it ended up being the exact location of a capital letter, the location of a number, or some combination of both. I could never figure out how a bug like that could even be coded up. My best guess is that it was some poorly-formed regex.<p>> Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems.
