The controller pattern is awful, and other OO heresy (2013)
Almost a year ago now, Jack Diederich gave a talk entitled “Stop Writing Classes“, in which he implores Python programmers to stop creating classes just for the hell of it, and specifically calls out the common pattern of a class with only a constructor/initializer and a single method—which should, of course, just be…
