Haskell symbols

When starting out with Haskell, I found it difficult to read a lot of the symbols. I made this document explaining the names of some symbols and how I read them.

x :: Int

// Only requirement: save all your .png files in 2x format. As this uses background-size, only IE9+ supported, but will look nice for both retina and non retina devices.
// Just because I like to use <span>s
.icon-sprite {
    display: inline-block;
}
// Compass automagically generate sprites
@import 'icon/*.png';
// Override the mixin Compass core uses to generate the width/height/position and include background-size
@mixin sprite-background-position($map, $sprite, $offset-x, $offset-y, $fifth) {
    $ypos: round(nth(sprite-position($map, $sprite), 2) / 2);

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

• rbenv
• ruby-build

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
