Rectifier

The diode bridge is the simplest rectifier I know.

Rectifier lets you share a directory with a docker container (just like $yourvm shared folders).

You don't have to install anything in your containers, and you only need to install diod in the host. diod is packaged on Ubuntu/Debian distros, and will automatically be apt-get install-ed if needed.

Since it uses diod to make a bridge, I called it rectifier. Yeah, that sucks, so if you have a better name, I'll steal it!

	# Version 1
	hash = Hash[hash.map { \|k, v\| [k.to_sym, v] }]

	# Version 2
	hash = hash.reduce({}) do \|memo, (k, v)\|
	memo.tap { \|m\| m[k.to_sym] = v }
	end
