# Due to a bug in Go, you can't `go get` a private Bitbucket repository
# (issue #5375, linked below). This means you can't `go get ./...` ANY project
# that might depend on a private Bitbucket repository.
#
# This script works around it by detecting Bitbucket imports and using
# `git` directly to clone into it. This will not work if you use private
# Mercurial repositories on Bitbucket.

Chapter 1

Every programming community quickly converges on a style, an accepted set of idioms. Programming is all about communication and knowing those idioms are key to being a successful programmer in that community.

Ruby style of programming:

• Code should be crystal clear, it should shout its intent
• Good code is also concise

Ruby indentation convention:

fnichol

##
# on each backend/non-routable cluster node
#

user_account "adminuser" do
  ssh_keygen true
  # other attributes perhaps?
end

# put the code in a ruby block so that it gets run in execution phase,
