The proof is by reductio ad absurdum, and reductio ad absurdum, which Euclid loved so much, is one of a mathematician’s finest weapons. It is a far finer gambit than any chess gambit: a chess player may offer the sacrifice of a pawn or even a piece, but a mathematician offers the game. -- G. H. Hardy

The good thing about reinventing the wheel is that you get a round one. -- Douglas Crockford (Author of JSON and JsLint)

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

Have you ever noticed that when you sit down to write something, half the ideas that end up in it are ones you thought of while writing it? The same thing happens with software. Working to implement one idea gives you more ideas. -- Paul Graham, The other road ahead.

A tail call allows a function to return the result of another function without leaving an entry on the stack. Tail recursion is a specific case of tail calling. -- ASPN : Python Cookbook : Explicit Tail Call

I don’t want to get to the end of my life and find that I lived just the length of it. I want to have lived the width of it as well. ~Diane Ackerman

I attribute my success to this: I never gave or took any excuse. –Florence Nightingale

The battles that count aren't the ones for gold medals. The struggles within yourself--the invisible battles inside all of us--that's where it's at. –Jesse Owens

You may be disappointed if you fail, but you are doomed if you don't try. –Beverly Sills
