# Elixir has lazily evaluated enumerable objects that allow you
# to work with enumerable objects like lists either only as needed
# or infinitely.

# Start up iex to play around
$ iex

# Typical enumeration is done eagerly where the result is computed ASAP
iex> Enum.map(1..10, fn i -> i * 2 end)

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

• XCode is installed (via the App Store)
• XCode command line tools are installed (xcode-select --install will prompt up a dialog)
• Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

5 entertaining things you can find with the GitHub Search API

Let's have some command-line fun with curl, [jq][1], and the [new GitHub Search API][2].

Today we're looking for:

• The hottest repositories created in the last week.
• The oldest user accounts with zero followers. (So sad.)
• Issue trends by language.
• Clojure projects defying convention.

	var os = require('os');

	if (os.type() == 'Darwin')

/**
 * Like, basically PERFECT scrollbars
 */

/* 
   It's pure CSS. 
   Since a quick google search will confirm people going crazy about Mac OS Lion scrollbars...
   this has no fade-out effect.
  
   In Mac OS Lion, the lowest common denominator is always showing scrollbars by a setting.

Setting Up Clojure on OS X

I spent a lot of time trying to find a pretty optimal (for me) setup for Clojure… at the same time I was trying to dive in and learn it. This is never optimal; you shouldn't be fighting the environment while trying to learn something.

I feel like I went through a lot of pain searching Google, StackOverflow, blogs, and other sites for random tidbits of information and instructions.

This is a comprehensive "what I learned and what I ended up doing" that will hopefully be of use to others and act as a journal for myself if I ever have to do it again. I want to be very step-by-step and explain what's happening (and why) at each step.

Step 1: Getting Clojure (1.3)
