Recently, I had a staging database on Heroku that was running on the Ronin database (which was originally the lowest-sized DB you could get at Heroku). Since they added two new options, Crane and Kappa, we wanted to take advantage of the cost savings. Here's how you can migrate your Ronin DB to Crane (or any other plan).

The old database was named BROWN while the new one is CRIMSON. You can determine this by running:

heroku pg:info --app myapp-staging

Add Crane database

 heroku addons:add heroku-postgresql:crane --app myapp-staging

heroku pg:wait --app myapp-staging

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

install packages for vim, git
create user accounts, as specified in included JSON config files
install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

Backstory: I decided to crowdsource static site generator recommendations, so the following are actual real world suggested-to-me results. I then took those and sorted them by language/server and, just for a decent relative metric, their Github Watcher count. If you want a heap of other projects (including other languages like Haskell and Python) Nanoc has the mother of all site generator lists. If you recommend another one, by all means add a comment.

	# Multi-value hashes in Ruby

	# Any non-trivial project quickly finds itself needing data structures that are more exotic than simple arrays or maps. In my quest for multimap
	# nirvana, I first found references where every value-put call would need to be changed to look like this:

	h = {}
	(h[:key] \|\|= []) << "value 1"
	(h[:key] \|\|= []) << "value 2"
	puts h

	#!/usr/bin/env ruby

	# Runs rubocop on just the modified and new files in a repoistory. Handy for
	# checking your compliance before you commit. It only runs against files that
	# end in .rb. Maybe it should do more than that?
	#
	# Easy to run. In a dirty working directory:
