Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live
--John Woods
A language that doesn't affect the way you think about programming is not worth knowing.
--Alan Perlis
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
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
Good programmers write code that humans can understand.
--Martin Fowler
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Martin Fowler
'Martyrdom' is the only way a person can become famous without ability.
--George Bernard Shaw
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
Some of the best programming is done on paper, really. Putting it into the computer is just a minor detail.
--Max Kanat-Alexander
When in doubt, do something.
--Harry Chapin
That's the thing about people who think they hate computers. What they really hate is lousy programmers.
--Larry Niven
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Nartin Fowler
Programming is the art of thinking really hard about how to avoid having to think really hard.
--unknown
Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
How do you expect to succeed if you do not know the rules?
--Anonymous
Happiness should be a function without any parameters.
--Pranshu Midha
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
Know the rules well, so you can break them effectively
--Dalai Lama XIV
It's got to be the going not the getting there that's good.
--Hary Chapin
Everyday life is like programming, I guess. If you love something you can put beauty into it.
--Donald Knuth
With software there are only two possibilites: either the users control the programme or the programme controls the users. If the programme controls the users, and the developer controls the programme, then the programme is an instrument of unjust power.
--Richard Stallman
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
Without requirements and design, programming is the art of adding bugs to an empty text file.
--Louis Srygley
Twenty hours at the keyboard can save you two hours of planning.
--Isaac Traxler
What kind of programmer is so divorced from reality that she thinks she'll get complex software right the first time?
--James Alan Gardner
There ain't no rules around here. We are trying to accomplish something.
--Thomas Edison
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
...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
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
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
