There is nothing good or bad about knowledge itself; morality lies in the application of knowledge.
--Jon Erickson
[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
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
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
The three principal virtues of a programmer are Laziness, Impatience, and Hubris. See the Camel Book for why.
--perldoc perl
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 best way to predict the future is to invent it
--Alan Kay
Simple things should be simple, complex things should be possible.
--Alan Kay
Premature optimization is the root of all evil.
--Donald Knuth
If the steps become to big, they become walls...
--Herb Sutter
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
...I’m not saying simple code takes less time to write. You’d think it would since you end up with less total code, but a good solution isn’t an accretion of code, it’s a distillation of it.
--Robert Nystrom
Programming isn't about what you know; it's about what you can figure out.
--Chris Pine
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
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
Programming is the art of thinking really hard about how to avoid having to think really hard.
--unknown
Good programmers write code that humans can understand.
--Martin Fowler
Know the rules well, so you can break them effectively
--Dalai Lama XIV
Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.
--Rick Cook
People who are really serious about software should make their own hardware
--Alan Kay
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
A change in perspective is worth 80 IQ points
--Alan Kay
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Nartin Fowler
When in doubt, do something.
--Harry Chapin
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
The big optimizations come from refining the high-level design, not the individual routines.
--Steve McConnell
The most difficult thing in the world is to know how to do a thing and to watch someone else do it wrong without comment.
--Theodore H. White
Learn the rules like a pro, so you can break them like an artist
--Pablo Picasso
