Premature optimization is the root of all evil.
--Donald Knuth
The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.
--perldoc perl
When in doubt, do something.
--Harry Chapin
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
Delivering good software today is often better than perfect software tomorrow, so finish things and ship.
--David Thomas
The most important property of a program is whether it accomplishes the intention of its user.
--C.A.R. Hoare
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
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
Perl – The only language that looks the same before and after RSA encryption.
--Keith Bostic
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
'Martyrdom' is the only way a person can become famous without ability.
--George Bernard Shaw
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
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Nartin Fowler
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 university is what a college becomes when the faculty loses interest in students.
--John Ciardi
That's the thing about people who think they hate computers. What they really hate is lousy programmers.
--Larry Niven
Think twice, code once.
--Waseem Latif
First solve the problem. Then, write the code.
--Waseem Latif
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
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
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
People who are really serious about software should make their own hardware
--Alan Kay
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.
Some of the best programming is done on paper, really. Putting it into the computer is just a minor detail.
--Max Kanat-Alexander
Know the rules well, so you can break them effectively
--Dalai Lama XIV
What is a university/college when the students lose interest?
--Isaac Traxler
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
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
Simple things should be simple, complex things should be possible.
--Alan Kay
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
