We control complexity by building abstractions that hide details when appropriate. We control complexity by establishing conventional interfaces that enable us to construct systems by combining standard, well-understood pieces in a ``mix and match'' way. We control complexity by establishing new languages for describing a design, each of which emphasizes particular aspects of the design and deemphasizes others. -- Alan J. Perlis
The lesson of the story might appear to be that self-interested and ambitious people in power are often the cause of wastefulness in developing countries. But self-interested and ambitious people are in positions of power, great and small, all over the world. In many places, they are restrained by the law, the press, and democratic opposition. Cameroon's tragedy is that there is nothing to hold self-interest in check. -- Tim Harford
The venerable master Qc Na was walking with his student, Anton. Hoping to prompt the master into a discussion, Anton said "Master, I have heard that objects are a very good thing - is this true?" Qc Na looked pityingly at his student and replied, "Foolish pupil - objects are merely a poor man's closures." Chastised, Anton took his leave from his master and returned to his cell, intent on studying closures. He carefully read the entire "Lambda: The Ultimate..." series of papers and its cousins, and implemented a small Scheme interpreter with a closure-based object system. He learned much, and looked forward to informing his master of his progress. On his next walk with Qc Na, Anton attempted to impress his master by saying "Master, I have diligently studied the matter, and now understand that objects are truly a poor man's closures." Qc Na responded by hitting Anton with his stick, saying "When will you learn? Closures are a poor man's object." At that moment, Anton became enlightened. -- Anton van Straaten (Na = Norman Adams, Qa = Christian Queinnec)
In order to understand what another person is saying, you must assume that it is true and try to find out what it could be true of. -- George Miller
I think it is wise, and only honest, to warn you that my goal is immodest. It is not my purpose to "transfer knowledge" to you that, subsequently, you can forget again. My purpose is no less than to effectuate in each of you a noticeable, irreversable change. I want you to gain, for the rest of your lives, the insight that beautiful proofs are not "found" by trial anf error but are the result of a consciously applied design discipline. I want you to raise your quality standards. I mean, if 10 years from now, when you are doing something quick and dirty, you suddenly visualize that I am looking over your shoulders and say to yourself "Dijkstra would not have liked this", well, that would be enough immortality for me. -- E. W. Dijkstra
Every man prefers belief to the exercise of judgment. -- Seneca
Most of the important things in the world have been accomplished by people who have kept on trying when there seemed to be no help at all. ~Dale Carnegie
If you want to achieve excellence, you can get there today. As of this second, quit doing less-than-excellent work. ~Thomas J. Watson
Education costs money. But then so does ignorance. –Sir Claus Moser
How wonderful it is that nobody need wait a single moment before starting to improve the world. –Anne Frank
