Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

curl -L https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh | sh

and then you change your shell to zsh

chsh -s `which zsh`

and then restart

This is how I explain it… Ruby has Procs and Lambdas. Procs are created with Proc.new { }, lambdas are created with lambda {} and ->() {}.

In Ruby 1.8, proc {} creates lambda, and Ruby 1.9 it creates procs (don't ask).

Lambdas use method semantics when handling parameters, procs use assignment semantics when handling parameters.

This means lambdas, like methods, will raise an ArgumentError when called with fewer arguments than they were defined with. Procs will simply assign nil to variables for arguments that were not passed in.

	Get the Heroku db as detailed here:
	http://devcenter.heroku.com/articles/pgbackups#exporting_via_a_backup

	1. heroku pgbackups:capture
	2. heroku pgbackups:url <backup_num> #=>backup_url
	- get backup_num with cmd "heroku pgbackups"
	3. curl -o latest.dump <backup_url>

	Then locally do:
	$ pg_restore --verbose --clean --no-acl --no-owner -h localhost -U myuser -d mydb latest.dump
