> It is not unusual —although a mistake— to consider the programmer's task to be the production of programs. (One finds terms such as "software manufacturing", proposals to measure programmer productivity by the number of lines of code produced per month etc., although I have never seen the suggestion to measure composer productivity by the number of notes, monthly scribbled on his score!).
47 years later, a lot of people still measure programming productivity by LOCs. Hell, even major freelance marketplaces try to track your every billed second by taking screenshots of your desktop or webcam "just to make sure you're working".
