Let me try to get this straight: Lisp is a language for describing algorithms. This was JohnMcCarthy's original purpose, anyway: to build something more convenient than a Turing machine. Lisp is not about file, socket or GUI programming - Lisp is about expressive power. (For example, you can design multiple object systems for Lisp, in Lisp. Or implement the now-fashionable AOP. Or do arbitrary transformations on parsed source code.) If you don't value expressive power, Lisp ain't for you. I, personally, would prefer Lisp to not become mainstream: this would necessarily involve a dumbing down. -- VladimirSlepnev

When you’ve got the code all ripped apart, it’s like a car that’s all disassembled. You’ve got all the parts tying all over your garage and you have to replace the broken part or the car will never run. It’s not fun until the code gets back to the baseline again. -- Gary Kildall (inventor of CP/M, one of the first OS for the micro).

In general, we can think of data as defined by some collection of selectors and constructors, together with specified conditions that these procedures must fulfill in order to be a valid representation. -- SICP, What is meant by data?

If you tell the truth, you don't have to remember anything. -- Mark Twain

A non negative binary integer value x is a power of 2 iff (x & (x-1)) is 0 using 2's complement arithmetic. -- [fact]

Life moves pretty fast. If you don't stop and look around once in a while, you could miss it. -- Ferris Bueller

Opportunities don’t happen, you create them. ~Chris Grosser

Whatever you can do, or dream you can, begin it. Boldness has genius, power and magic in it. –Johann Wolfgang von Goethe

You can’t connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something - your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life. ~Steve Jobs

A person who never made a mistake never tried anything new. – Albert Einstein
