Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches.
--Paul Graham
If the steps become to big, they become walls...
--Herb Sutter
Everyday life is like programming, I guess. If you love something you can put beauty into it.
--Donald Knuth
Good programmers write code that humans can understand.
--Martin Fowler
But while you can always write 'spaghetti code' in a procedural language, object-oriented languages used poorly can add meatballs to your spaghetti.
--Andrew Hunt
Simple things should be simple, complex things should be possible.
--Alan Kay
The best way to predict the future is to invent it
--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
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
Walking on water and developing software from a specification are easy if both are frozen.
--Edward V. Berard
How do you expect to succeed if you do not know the rules?
--Anonymous
Know the rules well, so you can break them effectively
--Dalai Lama XIV
I'm not a great programmer; I'm just a good programmer with great habits.
--Kent Beck
What is a university/college when the students lose interest?
--Isaac Traxler
Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.
--Edsger W. Dijkstra
What kind of programmer is so divorced from reality that she thinks she'll get complex software right the first time?
--James Alan Gardner
Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live
--John Woods
Premature optimization is the root of all evil.
--Donald Knuth
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
[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
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
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
--Nartin Fowler
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
A change in perspective is worth 80 IQ points
--Alan Kay
Programming is the art of thinking really hard about how to avoid having to think really hard.
--unknown
Delivering good software today is often better than perfect software tomorrow, so finish things and ship.
--David Thomas
How do you expect to succeed if you do not know the rules?
--Anonymous
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
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
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
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
