There ain't no rules around here. We are trying to accomplish something.
--Thomas Edison
Programming is the art of thinking really hard about how to avoid having to think really hard.
--unknown
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
A change in perspective is worth 80 IQ points
--Alan Kay
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
First solve the problem. Then, write the code.
--Waseem Latif
[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
What is a university/college when the students lose interest?
--Isaac Traxler
The big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
I'm not a great programmer; I'm just a good programmer with great habits.
--Kent Beck
Delivering good software today is often better than perfect software tomorrow, so finish things and ship.
--David Thomas
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
Perl – The only language that looks the same before and after RSA encryption.
--Keith Bostic
Learning the art of programming, like most other disciplines, consists of first learning the rules and then learning when to break them.
--Joshua Bloch
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 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
It goes against the grain of modern education to teach children to program. What fun is there in making plans, acquiring discipline in organizing thoughts, devoting attention to detail and learning to be self-critical?
--Alan J. Perlis
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
You are not reading this book because a teacher assigned it to you, you are reading it because you have a desire to learn, and wanting to learn is the biggest advantage you can have.
--Cory Althoff
