Be the change you want to see in the world. -- Mahatma Gandhi

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

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

It’s a problem if the design doesn’t let you add features at a later date. If you have to redo a program, the hours you spend can cause you to lose your competitive edge. A flexible program demonstrates the difference between a good designer and someone who is just getting a piece of code out. -- Gary Kildall (inventor of CP/M, one of the first OS for the micro).

Well, if you talk about programming to a group of programmers who use the same language, they can become almost evangelistic about the language. They form a tight-knit community, hold to certain beliefs, and follow certain rules in their programming. It’s like a church with a programming language for a Bible. -- Gary Kildall (inventor of CP/M, one of the first OS for the micro).

Things which matter most must never be at the mercy of things which matter least. -- Johann Wolfgang Von Goethe (1749-1832)

We become what we think about. –Earl Nightingale

Great minds discuss ideas; average minds discuss events; small minds discuss people. ~Eleanor Roosevelt

If you genuinely want something, don’t wait for it — teach yourself to be impatient. ~Gurbaksh Chahal

I’ve learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel. –Maya Angelou
