We are planning on building a Node.js service. Here's our evaluation of the current ORM landscape:

Objection.js
- http://vincit.github.io/objection.js/#introduction
- Bad: API is Promise based and bulky. This means people can forget to have an error handler due to not being error first
  - http://vincit.github.io/objection.js/#getting-started
- Good: Uses JSON schema for validation; this means content should be relatively reusable between server/browser

	# Unnecessary indexes slows down writes and consumes additional storage and memory.

	# Just paste this snippet in your Rails console (bundle exec rails c).
	# And it will print all redundant indexes that are already covered by another index on the table:
	# Table `pages`: index `site_idx` (site_id) already covered by `site_slug_idx` (site_id,slug)
	# Table `optins`: index `list_idx` (list_id) already covered by `list_active_idx` (list_id,active)


	ActiveRecord::Base.connection.tables.map do \|table\|
	indexes = ActiveRecord::Base.connection.indexes(table).select(&:valid).reject(&:where)

	# Hi all,
	# this is the Python code I used to make the visualization "Temperature circle"
	# (https://twitter.com/anttilip/status/892318734244884480).
	# Please be aware that originally I wrote this for my tests only so the
	# code was not ment to be published and is a mess and has no comments.
	# Feel free to improve, modify, do whatever you want with it. If you decide
	# to use the code, make an improved version of it, or it is useful for you
	# in some another way I would be happy to know about it. You can contact me
	# for example in Twitter (@anttilip). Unchecked demo data (no quarantees)

	# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env
	# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced
	# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start
	# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running.

	# Add the following to your shell init to set up gpg-agent automatically for every shell
	if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
