(person years now) I cannot find the message at the moment (TUHS mail archive search is not = working anymore?), but I recall that Doug McIlroy mentioned on this list = that 1973 was a miracle year, where Ken & Dennis wrote and debugged over = 100,000 lines of code between them. In software, =E2=80=9Cman year=E2=80=9D= is an elastic yardstick... There is also this anecdote by Andy Herzfeld: =3D=3D=3D Quickdraw, the amazing graphics package written entirely by Bill = Atkinson, was at the heart of both Lisa and Macintosh. "How many = man-years did it take to write QuickDraw?", the Byte magazine reporter = asked Steve [Jobs]. Steve turned to look at Bill. "Bill, how long did you spend writing = Quickdraw?" "Well, I worked on it on and off for four years", Bill replied. Steve paused for a beat and then turned back to the Byte reporter. = "Twenty-four man-years. We invested twenty-four man-years in QuickDraw." Obviously, Steve figured that one Atkinson year equaled six man years, = which may have been a modest estimate. =3D=3D=3D There is also another anecdote involving Atkinson. At some point all = Apple programmers had to file a weekly report with how many lines of = code they wrote that week. After a productive week of refactoring and = optimising, he filed a report saying =E2=80=9Cminus 2,000 lines=E2=80=9D.
