““Programming is not all the same. Normal written languages have different rhythms and idioms, right? Well, so do programming languages. The language called C is all harsh imperatives, almost raw computer-speak. The language called Lisp is like one long, looping sentence, full of subclauses, so long in fact that you usually forget what it was even about in the first place. The language called Erlang is just like it sounds: eccentric and Scandinavia. I cannot program in any of these languages because they're all too hard. But Ruby, my language of choice, was invented by a cheerful Japanese programmer, and it reads like friendly, accessible poetry. Billy Collins by way of Bill Gates.””
