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
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
Premature optimization is the root of all evil.
--Donald Knuth
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
How do you expect to succeed if you do not know the rules?

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
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Martin Fowler
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
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.
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Nartin Fowler
When they first built the University of California at Irvine they just put the buildings in. They did not put any sidewalks, they just planted grass. The next year, they came back and put the sidewalks where the trails were in the grass. Perl is just that kind of language. It is not designed from first principles. Perl is those sidewalks in the grass.
--Larry Wall
[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
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 big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
If the steps become to big, they become walls...
--Herb Sutter
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.
