Premature optimization is the root of all evil.
--Donald Knuth
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
One knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?
--Brian Kernighan
Some of the best programming is done on paper, really. Putting it into the computer is just a minor detail.
--Max Kanat-Alexander
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Martin Fowler
College is a waystation - the last convenience store on the road to life-long responsibility.
--Dennis Miller
A university is what a college becomes when the faculty loses interest in students.
--John Ciardi
Everyday life is like programming, I guess. If you love something you can put beauty into it.

Perl – The only language that looks the same before and after RSA encryption.
--Keith Bostic
That's the thing about people who think they hate computers. What they really hate is lousy programmers.
--Larry Niven
Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live
--John Woods
A language that doesn't affect the way you think about programming is not worth knowing.
--Unix Fortune
Learn the rules like a pro, so you can break them like an artist
--Pablo Picasso
People who are really serious about software should make their own hardware
--Alan Kay
What kind of programmer is so divorced from reality that she thinks she'll get complex software right the first time?
--James Alan Gardner
If the steps become to big, they become walls...
--Herb Sutter
[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
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
Learning the art of programming, like most other disciplines, consists of first learning the rules and then learning when to break them.
--Joshua Bloch
What is a university/college when the students lose interest?
--Isaac Traxler
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
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.
Delivering good software today is often better than perfect software tomorrow, so finish things and ship.
--David Thomas
How do you expect to succeed if you do not know the rules?
--Anonymous
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
The most disastrous thing that you can ever learn is your first programming language.
--Alan Kay
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
The big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
