This document has moved!

It's now here, in The Programmer's Compendium. The content is the same as before, but being part of the compendium means that it's actively maintained.

The "vcr.rb" spec helper in this gist will create cassettes with readable filename structures. It aims to avoid extremely long filenames for cassets that can break Docker builds.

For example:

# spec/features/life/quotes_widget_spec.rb
describe 'Life quotes widget', :vcr do
  context 'when the user knows their coverage amount' do
    it 'redirects to the health navigator' do
 # ...

Things that programmers don't know but should

(A book that I might eventually write!)

I imagine each of these chapters being about 2,000 words, making the whole book about the size of a small novel. For comparison, articles in large papers like the New York Times average about 1,200 words. Each topic gets whatever level of detail I can fit into that space. For simple topics, that's a lot of space: I can probably walk through a very basic, but working, implementation of the IP protocol.

What object-oriented programming advice is this code violating?
