xkcd Goodies: Regular Expressions Shirt

((?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{1-255})


This is the much-requested shirt based on xkcd's Comic #208. It warns everyone that you are not to be trifled with, that you have the situation well in hand, and that you can fix everything with a long jumble of indecipherable characters. (The expression on the front between the slashes is restrictive, but don't be greedy*?) On the back there is a hacker hero swinging in to save the day.

"/ Everybody stand back / I know regular expressions" on the front with a coding hero swinging in to save the day on the back of a black 100% cotton t-shirt.

*This product is imported.
