Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
[On identifying talented programmers] It’s just enthusiasm. You ask them what’s the most interesting program they worked on. And then you get them to describe it and its algorithms and what’s going on. If they can’t withstand my questioning on their program, then they’re not good. I’m asking them to describe something they’ve done that they’ve spent blood on. I’ve never met anybody who really did spend blood on something who wasn’t eager to describe what they’ve done and how they did it and why. I let them pick the subject. I don’t pick the subject, so I’m the amateur and they’re the professional in this subject. If they can’t stand an amateur asking them questions about their profession, then they don’t belong.
--Ken Thompson
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Nartin Fowler
The really good programmers spend a lot of time programming. I haven’t seen very good programmers who don’t spend a lot of time programming. If I don’t program for two or three days, I need to do it. And you get better at it—you get quicker at it. The side effect of writing all this other stuff is that when you get to doing ordinary problems, you can do them very quickly.
--Joe Armstrong
How do you expect to succeed if you do not know the rules?
--Anonymous
The issue of finding the best possible answer or achieving maximum efficiency usually arises in industry only after serious performance or legal troubles.
--Steven S. Skiena
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
There is nothing good or bad about knowledge itself; morality lies in the application of knowledge.
--Jon Erickson
The best way to predict the future is to invent it
--Alan Kay
People who are really serious about software should make their own hardware
--Alan Kay
If the steps become to big, they become walls...
--Herb Sutter
The most difficult thing in the world is to know how to do a thing and to watch someone else do it wrong without comment.
--Theodore H. White
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
It goes against the grain of modern education to teach children to program. What fun is there in making plans, acquiring discipline in organizing thoughts, devoting attention to detail and learning to be self-critical?
--Alan J. Perlis
Along every step of our journey through life, our mind is being programmed. If we are not programming it ourselves, someone else is doing it to us.
--Joseph Rain
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
When they first built the University of California at Irvine they just put the buildings in. They did not put any sidewalks, they just planted grass. The next year, they came back and put the sidewalks where the trails were in the grass. Perl is just that kind of language. It is not designed from first principles. Perl is those sidewalks in the grass.
--Larry Wall
The real nightmare, worse than the one in which the Big Machine wants to kill you, is the one in which it sees you as irrelevant, or not even as a discrete thing to know.
--Benjamin H Bratton
Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.
--Rick Cook
