  • UNIX is simple. But it just needs a genius to understand its simplicity. (Dennis Ritchie).
  • Good judgment comes from experience, and experience comes from bad judgment. (Fred Brooks).
  • Theory is when you know something, but it doesn’t work. Practice is when something works, but you don’t know why it works. Programmers combine theory and practice: Nothing works and they don’t know why.
  • It’s hard enough to find an error in your code when you’re looking for it; it’s even harder when you’ve assumed your code is error-free. (Steve McConnell)
  • The Six Phases of a Project:
    • Enthusiasm.
    • Disillusionment.
    • Panic.
    • Search for the Guilty.
    • Punishment of the Innocent.
    • Praise for non-participants.
  • Good code is its own best documentation. As you’re about to add a comment, ask yourself, ‘How can I improve the code so that this comment isn’t needed?’ Improve the code and then document it to make it even clearer. (Steve McConnell)
  • The trouble with the world is that the stupid are cocksure and the intelligent are full of doubt. (Bertrand Russell)
  • No matter how slick (efficient) the demo is in rehearsal, when you do it in front of a live audience the probability of a flawless presentation is inversely proportional to the number of people watching, raised to the power of the amount of money involved.
  • One of the main causes of the fall of the Roman Empire was that, lacking zero, they had no way to indicate successful termination of their C programs. (Robert Firth)
  • Fifty years of programming language research, and we end up with C++? (Richard A. O’Keefe)
  • C programmers never die. They are just cast into void.
  • If debugging is the process of removing bugs, then programming must be the process of putting them in. (Edsger Dijkstra)
  • There are two ways to write error-free programs; only the third works. (Alan J. Perlis)
  • Measuring programming progress by lines of code is like measuring aircraft building progress by weight. (Bill Gates)
  • Before software can be reusable, it first has to be usable. (Ralph Johnson)
  • Programmers are in a race with the Universe to create bigger and better idiot-proof programs, while the Universe is trying to create bigger and better idiots. So far the Universe is winning. (Anon)
  • As soon as we started programming, we found to our surprise that it wasn’t as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs. (Maurice Wilkes)
  • I did say something along the lines of “C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows your whole leg off.” (Bjarne Stroustrup)
  • Computers are useless. They can only give you answers. (Pablo Picasso)
  • Simplicity is prerequisite for reliability. (Edsger W.Dijkstra)
  • I’ve finally learned what “upward compatible” means. It means we get to keep all our old mistakes. (Dennie van Tassel)
  • Rules of Optimization:
    • Rule 1: Don’t do it.
    • Rule 2 (for experts only): Don’t do it yet. (M.A. Jackson)
  • Every program has (at least) two purposes: the one for which it was written, and another for which it wasn’t. (Alan J. Perlis)
  • Technology is dominated by two types of people: Those who understand what they do not manage. Those who manage what they do not understand. (Putt’s Law)
  • Copy and paste is a design error  (David Parnas)
  • Any code of your own that you haven’t looked at for six or more months might as well have been written by someone else.  (Eagleson’s law)
