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
Programming isn't about what you know; it's about what you can figure out.
--Chris Pine
[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
That's the thing about people who think they hate computers. What they really hate is lousy programmers.
--Larry Niven
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 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
A change in perspective is worth 80 IQ points
--Alan Kay
Some of the best programming is done on paper, really. Putting it into the computer is just a minor detail.
--Max Kanat-Alexander
Our consciousness is programmed. We see things a certain way from a young age - we're programmed to keep doing them that way. Then you have to spend adulthood learning how to overcome it, to read out the programs. Try to create. I want to tell people to create. Just start by creating your day. Then create your life.
--Prince
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
Think twice, code once.
--Waseem Latif
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
What is a university/college when the students lose interest?
--Isaac Traxler
Learn the rules like a pro, so you can break them like an artist
--Pablo Picasso
Not only is this incomprehensible, but the ink is ugly and the paper is from the wrong kind of tree.
--Professor W.
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
The most important property of a program is whether it accomplishes the intention of its user.
--C.A.R. Hoare
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
Perl – The only language that looks the same before and after RSA encryption.
--Keith Bostic
The best way to predict the future is to invent it
--Alan Kay
