for something like this in rails model

...  
validates :points, :numericality => {:greater_than_or_equal_to => 0}, :allow_nil => true
...

test can be :

it { should validate_numericality_of(:points) }

it { should_not allow_value(-1).for(:points) }

Your class can be no longer than 100 lines of code.
Your methods can be no longer than five lines of code.
You can pass no more than four parameters and you can’t just make it one big hash.
When a call comes into your Rails controller, you can only instantiate one object to do whatever it is that needs to be done. And your view can only know about one instance variable.

You can break these rules if you can talk your pair into agreeing with you.

Domain-Driven Desire: The Talk from Øredev 2016

Thanks for watching my talk, Domain-Driven Desire at Øredev 2016. Here's a list of resources that inspired me, and will hopefully inspire you:

	cd /tmp
	wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm
	rpm -Uhv rpmforge-release*.rf.i386.rpm
	yum install readline-dev htop

	Background

	Raise.com is built on top of Spree. We have in-lined spree, and have decorators
	on the models to beat the band. We want to move away from Spree altogeher.
	This involves taking the models from Spree, moving them to the Raise
	base app. This merge has the potential to create lots of big classes. Big classes
	are difficult to maintain. One of the first steps towards returning classes/models to
	being "right sized." is splitting the business logic and the persistence.

	What I did

	# Integer vs Float div by zero gotchas

	#
	1 / 0 = [answer]
	1.0 / 0 = [answer]
	1 / 0.0 = [answer]
	0 / 0.0 = [answer]

	# String concatenation vs interpolation
	x = 5
