If you write a lot of programs, and you're used to squeezing them all the time, you find that it's easy to write a program that's simple. A lot of it is having a clear sense of what you want to say — writing the proof by choosing what to prove, and being clear about that. In programming, a lot of simplicity comes from knowing what matters and what doesn't matter.

You see, some people have a talent for programming. At ten to thirteen years old, typically, they're fascinated, and if they use a program, they want to know: “How does it do this?” But when they ask the teacher, if it's proprietary, the teacher has to say: “I'm sorry, it's a secret, we can't find out.” Which means education is forbidden. A proprietary program is the enemy of the spirit of education. It's knowledge withheld, so it should not be tolerated in a school, even though there may be plenty of people in the school who don't care about programming, don't want to learn this. Still, because it's the enemy of the spirit of education, it shouldn't be there in the school.
But if the program is free, the teacher can explain what he knows, and then give out copies of the source code, saying: “Read it and you'll understand everything.” And those who are really fascinated, they will read it! And this gives them an opportunity to start to learn how to be good programmers.
To learn to be a good programmer, you'll need to recognize that certain ways of writing code, even if they make sense to you and they are correct, they're not good because other people will have trouble understanding them. Good code is clear code that others will have an easy time working on when they need to make further changes.
How do you learn to write good clear code? You do it by reading lots of code, and writing lots of code. Well, only free software offers the chance to read the code of large programs that we really use. And then you have to write lots of code, which means you have to write changes in large programs.
How do you learn to write good code for the large programs? You have to start small, which does not mean small program, oh no! The challenges of the code for large programs don't even begin to appear in small programs. So the way you start small at writing code for large programs is by writing small changes in large programs. And only free software gives you the chance to do that.

"Much of my work has come from being lazy. I didn't like writing programs, and so, when I was working on the IBM 701 (an early computer), writing programs for computing missile trajectories, I started work on a programming system to make it easier to write programs."

 

John Backus

 

So today, let's write a program simply. But let's also realize that tomorrow, we're going to make it more complex, because tomorrow it's going to do more. So we'll take that simplicity and we'll lose some of it. But tomorrow, hopefully tomorrow's program is as simple as possible for tomorrow's needs. Hopefully we'll preserve simplicity as the program grows.

Nine-tenths of the value of a sense of humor in writing is not in the things it makes one write but in the things it keeps one from writing. It is especially valuable in this respect in serious writing, and no one without a sense of humor should ever write seriously. For without knowing what is funny, one is constantly in danger of being funny without knowing it.

 

Robert Benchley

 

[As a screenwriter] I have a sense of exile from thought, a nostalgia of the quiet room and balanced mind. I am a writer, and there comes a time when that which I write has to belong to me, has to be written alone and in silence, with no one looking over my shoulder, no one telling me a better way to write it. It doesn't have to be great writing, it doesn't even have to be terribly good. It just has to be mine.
