After reading Code Climate's Rails' Insecure Defaults I realized I was guilty of breaking rule 3. Versioned Secret Tokens. Here's how I fixed it.
Use dotenv in development and test environments:
# Gemfile
gem 'dotenv-rails', groups: [:development, :test]
| #!/usr/bin/env ruby | |
| require 'mail' # gem install mail --no-document | |
| # Credit to : | |
| # http://stackoverflow.com/questions/12884711/how-to-send-email-via-smtp-with-rubys-mail-gem | |
| def ask question | |
| print "#{question} ? : " | |
| $stdin.gets.chomp! | |
| end |
| #!/usr/bin/env ruby | |
| require 'nokogiri' # gem install nokogiri --no-document | |
| require 'net/http' | |
| require 'json' | |
| require 'cgi' | |

| # $ ruby howdoi.rb format date bash | |
| # > DATE=`date +%Y-%m-%d` |
| $ gem list --verbose -r | |
