“Of course, the test difficulty depends on what you're doing, and on how you're doing it. I'm constantly asking "How much would I have to screw this up to write an incorrect function that passes these simple tests?" Occasionally the answer is "Not much," so I'll throw the code away and start over. It was probably perfect code, but that's not good enough.”

“Sure, when you're in the midst of your own suffering, it's easy to convince yourself that you're no good—but we are all tested in this life… The measure of a man is not how much he suffers in the test, but how he comes out at the end.”

Neal Shusterman (1962) American novelist

“The true test of intelligence is not how much we know how to do, but how we behave when we don't know what to do”

John Holt book How Children Fail

How Children Fail (1964).

“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.”

“What should I write?
What can I say?
How can I tell you how much I miss you?
The weather here has been as nice as it can be,
Although it doesn't really matter much to me.
For all the fun I'll have while you're so far away,
It might as well rain until September.”

Carole King (1942) Nasa

“I find if you're targeting Windows, Linux, and Mac OS X right from the start, your code will probably work anywhere else that you might try it later… Writing code that is cross-platform from the start requires more discipline, but I find it is worth the effort.”

“And so, what we've done all of these years is very simple, is use the little tool, which is ask three whys in a row. Because the first why you always have a good answer for. The second why, it starts getting difficult. By the third why, you don't really know why you're doing what you're doing.”

“I'm safe,
Up high.
Nothing can touch me.
But why do I feel this party's over?
No pain,
Inside.
You're like protection.
How do I feel this good sober?”
