Quotes on Computer Language

If you stay up late and you have another hour of work to do, you can just stay up another hour later without running into a wall and having to stop. Whereas it might take three or four hours if you start over, you might finish if you just work that extra hour. If you're a morning person, the day always intrudes a fixed amount of time in the future. So it's much less efficient. Which is why I think computer people tend to be night people - because a machine doesn't get sleepy.

The tools we use have a profound and devious influence on our thinking habits, and therefore on our thinking abilities.

A most important, but also most elusive, aspect of any tool is its influence on the habits of those who train themselves in its use. If the tool is a programming language this influence is, whether we like it or not, an influence on our thinking habits.... A programming language is a tool that has profound influence on our thinking habits.

A good programming language is a conceptual universe for thinking about programming.

Simple things should be simple and complex things should be possible.

Awaken people's curiosity. It is enough to open minds, do not overload them. Put there just a spark.

In those days [batch processing] programmers never even documented their programs, because it was assumed that nobody else would ever use them. Now, however, time-sharing had made exchanging software trivial: you just stored one copy in the public repository and therby effectively gave it to the world. Immediately people began to document their programs and to think of them as being usable by others. They started to build on each other's work.

We think only through the medium of words. Languages are true analytical methods. Algebra, which is adapted to its purpose in every species of expression, in the most simple, most exact, and best manner possible, is at the same time a language and an analytical method. The art of reasoning is nothing more than a language well arranged.

I can only think that the book is read because it deals with the difficulties of schooling, which do not change. Please note: the difficulties, not the problems. Problems are solved or disappear with the revolving times. Difficulities remain. It will always be difficult to teach well, to learn accurately; to read, write, and count readily and competently; to acquire a sense of history and start one's education or anothers.

First, we want to establish the idea that a computer language is not just a way of getting a computer to perform operations but rather that it is a novel formal medium for expressing ideas about methodology. Thus, programs must be written for people to read, and only incidentally for machines to execute.

The ability to simplify means to eliminate the unnecessary so that the necessary may speak.

If you want truly to understand something, try to change it.

A ship in port is safe, but that's not what ships are built for.

An excellent plumber is infinitely more admirable than an incompetent philosopher.

If you're as clever as you can be when you write it, how will you ever debug it?

The programmer, like the poet, works only slightly removed from pure thought-stuff. He builds his castles in the air, from air, creating by exertion of the imagination. Few media of creation are so flexible, so easy to polish and rework, so readily capable of realizing grand conceptual structures.

It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration.

Make everything as simple as possible, but not simpler.

A programming language is like a natural, human language in that it favors certain methaphors, images, and ways of thinking.

When certain concepts of TeX are introduced informally, general rules will be stated; afterwards you will find that the rules aren't strictly true. In general, the later chapters contain more reliable information than the earlier ones do. The author feels that this technique of deliberate lying will actually make it easier for you to learn the ideas. Once you understand a simple but false rule, it will not be hard to supplement that rule with its exceptions.
