I'm not a great programmer; I'm just a good programmer with great habits.
--Kent Beck
Learning the art of programming, like most other disciplines, consists of first learning the rules and then learning when to break them.
--Joshua Bloch
What kind of programmer is so divorced from reality that she thinks she'll get complex software right the first time?
--James Alan Gardner
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
First solve the problem. Then, write the code.
--Waseem Latif
What is a university/college when the students lose interest?
--Isaac Traxler
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
A change in perspective is worth 80 IQ points
--Alan Kay
Good programmers write code that humans can understand.
--Martin Fowler
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
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
The most important property of a program is whether it accomplishes the intention of its user.
--C.A.R. Hoare
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 ain't no rules around here. We are trying to accomplish something.
--Thomas Edison
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
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.
Our consciousness is programmed. We see things a certain way from a young age - we're programmed to keep doing them that way. Then you have to spend adulthood learning how to overcome it, to read out the programs. Try to create. I want to tell people to create. Just start by creating your day. Then create your life.
--Prince
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
One knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?
--Brian Kernighan
People who are really serious about software should make their own hardware
--Alan Kay
A language that doesn't affect the way you think about programming is not worth knowing.
--Unix Fortune
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
Learn the rules like a pro, so you can break them like an artist
--Pablo Picasso
So if an algorithm is an idealized recipe, a program is the detailed set of instructions for a cooking robot preparing a month of meals for an army while under enemy attack
--Kernighan Brian
The best way to predict the future is to invent it
--Alan Kay
Happiness should be a function without any parameters.
--Pranshu Midha
There is nothing good or bad about knowledge itself; morality lies in the application of knowledge.
--Jon Erickson
...I’m not saying simple code takes less time to write. You’d think it would since you end up with less total code, but a good solution isn’t an accretion of code, it’s a distillation of it.
--Robert Nystrom
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
[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
That's the thing about people who think they hate computers. What they really hate is lousy programmers.
--Larry Niven
The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.
--perldoc perl
Managers of programming projects aren’t always aware that certain programming issues are matters of religion. If you’re a manager and you try to require compliance with certain programming practices, you’re inviting your programmers’ ire. Here’s a list of religious issues:
■ Programming language
■ Indentation style
■ Placing of braces
■ Choice of IDE
■ Commenting style
■ Efficiency vs. readability tradeoffs
■ Choice of methodology—for example, Scrum vs. Extreme Programming vs. evolutionary delivery ■ Programming utilities
■ Naming conventions
■ Use of gotos
■ Use of global variables
■ Measurements, especially productivity measures such as lines of code per day
--Steve McConnell
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
