For the people who prefer to bikeshed around gender issues and don't know their history of programming languages: this is not just a pun on that book, but also on the essay "Real Programmers Don't Use Pascal" published in Datamation magazine in 1983. Which is by the way correct in pointing out that Real Men use neither Vi nor Emacs, but TECO. Oh yeah, and Real Man is a gender-neutral title in this context, like "fireman".
