Some of the best programming is done on paper, really. Putting it into the computer is just a minor detail.
--Max Kanat-Alexander
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
People who are really serious about software should make their own hardware
--Alan Kay
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Martin Fowler
I'm a programmer. I like programming. And the best way I've found to have a positive impact on code is to write it.
--Robert C. Martin
Happiness should be a function without any parameters.
--Pranshu Midha
Premature optimization is the root of all evil.
--Donald Knuth
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
Not only is this incomprehensible, but the ink is ugly and the paper is from the wrong kind of tree.
--Professor W.
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
Know the rules well, so you can break them effectively
--Dalai Lama XIV
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
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
The most disastrous thing that you can ever learn is your first programming language.
--Alan Kay
How do you expect to succeed if you do not know the rules?
--Anonymous
It's got to be the going not the getting there that's good.
--Hary Chapin
Perl – The only language that looks the same before and after RSA encryption.
--Keith Bostic
