[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
A language that doesn't affect the way you think about programming is not worth knowing.
--Alan Perlis
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
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 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
I'm a programmer. I like programming. And the best way I've found to have a positive impact on code is to write it.
--Robert C. Martin
How do you expect to succeed if you do not know the rules?
--Anonymous
Simple things should be simple, complex things should be possible.
--Alan Kay
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
People who are really serious about software should make their own hardware
--Alan Kay
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
The big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
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
Happiness should be a function without any parameters.
--Pranshu Midha
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
What kind of programmer is so divorced from reality that she thinks she'll get complex software right the first time?
--James Alan Gardner
Know the rules well, so you can break them effectively
--Dalai Lama XIV
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 three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.
--perldoc perl
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
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
The best way to predict the future is to invent it
--Alan Kay
A change in perspective is worth 80 IQ points
--Alan Kay
Learning the art of programming, like most other disciplines, consists of first learning the rules and then learning when to break them.
--Joshua Bloch
If the steps become to big, they become walls...
--Herb Sutter
There ain't no rules around here. We are trying to accomplish something.
--Thomas Edison
...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
Programming is the art of thinking really hard about how to avoid having to think really hard.
--unknown
Programming isn't about what you know; it's about what you can figure out.
--Chris Pine
The most important property of a program is whether it accomplishes the intention of its user.
--C.A.R. Hoare
Some of the best programming is done on paper, really. Putting it into the computer is just a minor detail.
--Max Kanat-Alexander
What is a university/college when the students lose interest?
--Isaac Traxler
There is nothing good or bad about knowledge itself; morality lies in the application of knowledge.
--Jon Erickson
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.
I'm not a great programmer; I'm just a good programmer with great habits.
--Kent Beck
A university is what a college becomes when the faculty loses interest in students.
--John Ciardi
