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
People who are really serious about software should make their own hardware
--Alan Kay
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Nartin Fowler
[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
Simple things should be simple, complex things should be possible.
--Alan Kay
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
It's got to be the going not the getting there that's good.
--Hary Chapin
Good programmers write code that humans can understand.
--Martin Fowler
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
A language that doesn't affect the way you think about programming is not worth knowing.
--Unix Fortune
First solve the problem. Then, write the code.
--Waseem Latif
The best way to predict the future is to invent it
--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.
Think twice, code once.
--Waseem Latif
Premature optimization is the root of all evil.
--Donald Knuth
I'm not a great programmer; I'm just a good programmer with great habits.
--Kent Beck
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 most important property of a program is whether it accomplishes the intention of its user.
--C.A.R. Hoare
A change in perspective is worth 80 IQ points
--Alan Kay
Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live
--John Woods
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
A language that doesn't affect the way you think about programming is not worth knowing.
--Alan Perlis
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
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
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
