Know the rules well, so you can break them effectively
--Dalai Lama XIV
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
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
[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
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 disastrous thing that you can ever learn is your first programming language.
--Alan Kay
There is nothing good or bad about knowledge itself; morality lies in the application of knowledge.
--Jon Erickson
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.
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
The best way to predict the future is to invent it
--Alan Kay
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
That's the thing about people who think they hate computers. What they really hate is lousy programmers.
--Larry Niven
Premature optimization is the root of all evil.
--Donald Knuth
First solve the problem. Then, write the code.
--Waseem Latif
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
College is a waystation - the last convenience store on the road to life-long responsibility.
--Dennis Miller
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
A university is what a college becomes when the faculty loses interest in students.
--John Ciardi
Programming is the art of thinking really hard about how to avoid having to think really hard.
--unknown
People who are really serious about software should make their own hardware
--Alan Kay
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
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.
The big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
When in doubt, do something.
--Harry Chapin
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
