Setting up and installing rbenv, ruby-build, rubies, rbenv-gemset, and bundler

This guide enables you to install (ruby-build) and use (rbenv) multiple versions of ruby, isolate project gems (gemsets and/or bundler), and automatically use appropriate combinations of rubies and gems.

TL;DR Demo

# Ensure system is in ship-shape.

aptitude install git zsh libssl-dev zlib1g-dev libreadline-dev libyaml-dev

Rainbow stripe mixin with SCSS + Compass

I'm trying to make a horizontal rainbow stripe background gradient mixin, but I feel like this is way too verbose. How can it be better?

Goals:

1. [check] Use variables for colors so they can be swapped out for different colors.
2. [check] The widths are hard coded for 8 colors. Can it be done smarter where it adjusts to the number of colors you add? Or is that asking too much?
3. [check] The colors are defined twice for the color starts and stops. Can this be done better?
4. [see below] Right now I define the colors as variables at the top level, then pass them in the mixin. Should they instead be created inside the mixin and then colors are brought in as arguments? Or does that matter?

Im Rubymotion and MacRuby you can use all the Ruby Lambda syntaxes that are:

block = lambda { |param|  ... }

Why should you care about ES6 (the next edition of JavaScript)? Won't you have to wait decades in order to be able to use it?

No, for three reasons.

Node.js

Node.js uses a relatively up-to-date version of v8, the JavaScript engine from Chrome. The Chrome team participates in TC39 (the committee that makes JavaScript) and is tracking the progress of ES6 very closely.

If you're using node.js, you can already start taking advantage of some parts of ES6, and will probably be able to use all of the ES6 features once it is standardized in 2013.
