A pattern for testing class methods in ruby with rspec explicit subjects
# RSpec's subject method, both implicitly and explicitly set, is useful for
# declaratively setting up the context of the object under test. If you provide a
# class for your describe block, subject will implicitly be set to a new instance
# of this class (with no arguments passed to the constructor). If you want
# something more complex done, such as setting arguments, you can use the
# explicit subject setter, which takes a block.
describe Person do
context "born 19 years ago" do
subject { Person.new(:birthdate => 19.years.ago }
it { should be_eligible_to_vote }

Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Below are simple styles to "flatten" bootstrap. I didn't go through every control and widget that bootstrap offers, only what was required for https://commando.io, so your milage may vary.

a simple git branching model

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.
