  puts row
end

The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Most \d commands support additional param of __schema__.name__ and accept wildcards like *.*

If you have two days to learn the very basics of modelling, Domain-Driven Design, CQRS and Event Sourcing, here's what you should do:

In the evenings read the [Domain-Driven Design Quickly Minibook]{http://www.infoq.com/minibooks/domain-driven-design-quickly}. During the day watch following great videos (in this order):

	#
	# If this script exits with a non-zero status nothing will be pushed.

	# Steps to install, from the root directory of your repo...
	# 1. Copy the file into your repo at `.git/hooks/pre-push`
	# 2. Set executable permissions, run `chmod +x .git/hooks/pre-push`
