My first program taught me a lot about the errors that I was going to be making in the future, and also about how to find errors. That's sort of the story of my life, making errors and trying to recover from them. I try to get things correct. I probably obsess about not making too many mistakes.
Interpretation
Learning from mistakes is essential for growth and improvement.
In this quote, Donald Knuth reflects on the importance of errors in the process of learning and personal development. He emphasizes that making mistakes is a natural part of life and that the true value lies in understanding how to identify and correct them, which contributes to overall improvement and mastery in any field, particularly in programming and life itself.
In practice
In a presentation about embracing failure in tech startups, this quote emphasizes the learning process.
Computer programming is an art, because it applies accumulated knowledge to the world, because it requires skill and ingenuity, and especially because it produces objects of beauty. A programmer who subconsciously views himself as an artist will enjoy what he does and will do it better.
The hardest thing is to go to sleep at night, when there are so many urgent things needing to be done. A huge gap exists between what we know is possible with today's machines and what we have so far been able to finish.
An algorithm must be seen to be believed.
The process of preparing programs for a digital computer is especially attractive, not only because it can economically and scientifically rewarding, but also because it can be an aesthetic experience much like composing poetry or music.
People who are more than casually interested in computers should have at least some idea of what the underlying hardware is like. Otherwise the programs they write will be pretty weird.
Everyday life is like programming, I guess. If you love something you can put beauty into it.
You expect far too much of a first sentence. Think of it as analagous to a good country breakfast: what we want is something simple, but nourishing to the imagination. Hold the philosophy, hold the adjectives, just give us a plain subject and verb and perhaps a wholesome, nonfattening adverb or two.
Actually if a writer needs a dictionary he should not write. He should have read the dictionary at least three times from beginning to end and then have loaned it to someone who needs it. There are only certain words which are valid and similes (bring me my dictionary) are like defective ammunition (the lowest thing I can think of at this time).
Good teaching must be slow enough so that it is not confusing, and fast enough so that it is not boring.
To educate a man in mind and not in morals is to educate a menace to society.
My family was well off but not rich. I spent the four years I was an undergraduate working on the beach. And it wasn't because I was lazy; it was because my freshman class would go to a hundred different employers and wouldn't get a nibble. That was a disequilibrium system. I realized that the ordinary old-fashioned Euclidean geometry didn't apply.
The world is rated R, and no one is checking IDs. Do not try to make it G by imagining the shadows away. Do not try to hide your children from the world forever, but do not pretend there is no danger . Train them. Give them sharp eyes and bellies full of laughter. Make them dangerous. Make them yeast, and when they’ve grown, they will pollute the shadows.
