Programming is the art of thinking really hard about how to avoid having to think really hard.

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
Einstein repeatedly argued that there must be simplified explanations of nature, because God is not capricious or arbitrary. No such faith comforts the software engineer.
--Frederick P. Brooks Jr.
The big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
A change in perspective is worth 80 IQ points
--Alan Kay
People who are really serious about software should make their own hardware
--Alan Kay
But while you can always write 'spaghetti code' in a procedural language, object-oriented languages used poorly can add meatballs to your spaghetti.
--Andrew Hunt
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
A language that doesn't affect the way you think about programming is not worth knowing.
--Alan Perlis
The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.
--perldoc perl
Happiness should be a function without any parameters.
--Pranshu Midha
The most important property of a program is whether it accomplishes the intention of its user.
--C.A.R. Hoare
There ain't no rules around here. We are trying to accomplish something.
--Thomas Edison
You are not reading this book because a teacher assigned it to you, you are reading it because you have a desire to learn, and wanting to learn is the biggest advantage you can have.
--Cory Althoff
That's the thing about people who think they hate computers. What they really hate is lousy programmers.
--Larry Niven
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
First solve the problem. Then, write the code.
--Waseem Latif
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
I'm not a great programmer; I'm just a good programmer with great habits.
--Kent Beck
With software there are only two possibilites: either the users control the programme or the programme controls the users. If the programme controls the users, and the developer controls the programme, then the programme is an instrument of unjust power.
--Richard Stallman
College is a waystation - the last convenience store on the road to life-long responsibility.
--Dennis Miller
Think twice, code once.
--Waseem Latif
