List of features that are supported by Opera 12 but not by Opera 15 due to the switch to Blink/Chromium:

• xhr.responseType = 'json' fixed as of August 19, 2013
• Link HTTP header
• Link HTTP header for stylesheets specifically
• Pressing Enter when an element with tabindex has focus should trigger a click
• Fragment identifiers in data: URIs should be handled correctly
• CSS gradients with transparency
• Accurate SVG rendering
• [`` where foo.svg is an SVG file that contains text looks terrible](https://code.google.com/p/chromium/issues/detail?id=33

First, you install ruby-build and chruby. ruby-build is a program that knows how to download and build different ruby versions. chruby manages $PATH to control which ruby gets invoked in your shell. They work completely independently.

sudo su
cd /usr/src

git clone https://github.com/sstephenson/ruby-build.git
cd ruby-build
./install.sh
cd -

# Usage: move this file to ~/bin/ and create a link ~/bin/psa-full -> psa.
# `psa STRING` will show you the output clipped to current number of columns in
# the terminal, `psa-full STRING` will give the full output.
# Tested on OS X 10.9-10.10.

if [[ "`basename "$0"`" == *-full ]]; then
	COLS=10000
