Delivering good software today is often better than perfect software tomorrow, so finish things and ship.
--David Thomas
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
Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live
--John Woods
Simple things should be simple, complex things should be possible.
--Alan Kay
Know the rules well, so you can break them effectively
--Dalai Lama XIV
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 big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
I'm not a great programmer; I'm just a good programmer with great habits.
--Kent Beck
Happiness should be a function without any parameters.
--Pranshu Midha
[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
Some of the best programming is done on paper, really. Putting it into the computer is just a minor detail.
--Max Kanat-Alexander
If the steps become to big, they become walls...
--Herb Sutter
Perl – The only language that looks the same before and after RSA encryption.
--Keith Bostic
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 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
A language that doesn't affect the way you think about programming is not worth knowing.
--Alan Perlis
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
Not only is this incomprehensible, but the ink is ugly and the paper is from the wrong kind of tree.
--Professor W.
It's got to be the going not the getting there that's good.
--Hary Chapin
...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
The personal computer isn't "personal" because it's small and portable and yours to own. It's "personal" because you pour yourself into it - your thoughts, your programming.
--Audrey Watters
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
The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.
--perldoc perl
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
People who are really serious about software should make their own hardware
--Alan Kay
