Install OS X 10.10 Yosemite in VirtualBox

(based on this pastebin i've found via Google, markdownified and adjusted to work with the official Yosemite release)

Yosemite's first developer preview was released right after Monday's WWDC opening keynote. For the general public, an open beta will be available to download later this summer. However, for those who want a sneak peek at the new hotness, there is a way to safely install it without risking your machine, using the free and powerful VirtualBox application from Oracle.

(LEGAL DISCLAIMER: This guide aims to explain how to create a virtual machine on a regularly purchased Apple computer, running a genuine Mac OS X operating system, for testing purposes only.)

Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

	do shell script "xcode-select --install"
	do shell script "sleep 1"

	tell application "System Events"
	tell process "Install Command Line Developer Tools"
	keystroke return
	click button "Agree" of window "License Agreement"
	end tell
	end tell

	#!/bin/sh
	OSX_VERS=$(sw_vers -productVersion \| awk -F "." '{print $2}')

	# Get Xcode CLI tools
	# https://devimages.apple.com.edgekey.net/downloads/xcode/simulators/index-3905972D-B609-49CE-8D06-51ADC78E07BC.dvtdownloadableindex
	TOOLS=clitools.dmg
	if [ ! -f "$TOOLS" ]; then
	if [ "$OSX_VERS" -eq 7 ]; then
	DMGURL=http://devimages.apple.com/downloads/xcode/command_line_tools_for_xcode_os_x_lion_april_2013.dmg
	elif [ "$OSX_VERS" -eq 8 ]; then

	source 'https://rubygems.org'

	gem 'rails', '4.0.2'
	gem "redis-rails", "~> 4.0.0"
	gem 'puma'
	gem 'unicorn'

	# Use sqlite3 as the database for Active Record
	gem 'sqlite3'

	# be sure to comment out the require 'capistrano/deploy' line in your Capfile!

	# config valid only for Capistrano 3.1
	lock '3.2.1'

	set :application, 'my-cool-application'

	# the base docker repo reference
	set :name, "johns-stuff/#{fetch(:application)}"
