Installing Graphite on OS X Lion

This is a general overview (from memory) of the steps I used to install graphite (http://graphite.wikidot.com) on OS X Lion. I think the steps are in order but YMMV. Please fork and fix if you find an error.

Install Python 2.7.2

brew install python

Check your env

$ python --version

True and False vs. "Truthy" and "Falsey" (or "Falsy") in Ruby, Python, and JavaScript

true and false vs. "truthy" and "falsey" (or "falsy") in Ruby, Python, and JavaScript

Many programming languages, including Ruby, have native boolean (true and false) data types. In Ruby they're called true and false. In Python, for example, they're written as True and False. But oftentimes we want to use a non-boolean value (integers, strings, arrays, etc.) in a boolean context (if statement, &&, ||, etc.).

This outlines how this works in Ruby, with some basic examples from Python and JavaScript, too. The idea is much more general than any of these specific languages, though. It's really a question of how the people designing a programming language wants booleans and conditionals to work.
