Hi spec
# I know what you are saying about the composition.
# I know that this simple example doesn't represent the
# composability that you probably trying to do.
# But this is how I would do what you want.
# You already know all this so I'm wasting your time actually.
# =>
# hi!
# hi!
# hello!

Lunch Spec
# RSpec really does have an identity crisis. It's not quite ruby and it's
# not quite English. But what if we really made our tests complicated
# with shared_examples that behave like mixins sorta? How bad would this be?
# rspec --format doc lunch_spec.rb
shared_examples "charge" do
let(:cash_register) { "ding!" }
it "charges a price" do

Sometimes Things Have Their Own Purpose
Guy at coffee shop. I'm playing with my adafruit goggles, trying to make a part list.
Guy: What's that.
Me: LED Goggles.
Guy: Do they let you see in 3D.
Me: No.
Guy: Do they let you ride your bike at night?
Me: They aren't that bright.
Guy: Do they let you read better.
Me: Actually they sort of blind you.

postgres is pretty sweet

Postgres is pretty awesome

blog post draft

Basics

Get up and running. Install it. I'm sure you know how. But then maybe you are used to mysql>? Where is the database? How do I even start?

  1. sudo -u postgres -i - This is your system account that pg runs as. Switch to it and we'll create a sandbox database.
  2. createuser name - Where "name" is your normal user account you use.
  3. createdb name -O name - Where "name" is your normal user account you use.
