Ideally one would desire an indefinitely large memory capacity such that any particular...word would be immediately available... We are...forced to recognize the possibility of constructing a hierarchy of memories, each of which has greater capacity then the preceding but which is less quickly accessible.

One purpose of CRC cards [a design tool] is to fail early, to fail often, and to fail inexpensively. It is a lot cheaper to tear up a bunch of cards that it would be to reorganize a large amount of source code.

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil.

As soon as we started programming, we found to our surprise that it wasn't as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programmes.
