Nitrous is a powerful IDE (integrated development environment) for building and previewing web applications. With a live console, text editor (with syntax highlighting), and server with preview options, it has everything you need to develop for Bloc Courses.
Creating an account is simple. Go to nitrous.io and enter in a username, password and email. You can even use your Github account to login if you're wary of creating another account for a singular purpose.
SSH to the vagrant OS command line.
Terminal $> vagrant ssh
Login to postgres database as vagrant user with the psql client:
vagrant@rails-dev-box: psql -U vagrant postgres
Rails changed the default behavior for WEBrick somewhere around version 4. Instead of binding to 0.0.0.0, it will now default to localhost.
This makes life difficult when you're running Rails inside a VM like Vagrant, mostly because it won't work. ;)
Fortunately, you can force Rails back into the old universal address with the following snippet
# config/boot.rb
# ... end of existing file
| if Rails.env.development? | |
| Rails.application.assets.logger = Logger.new('/dev/null') | |
| Rails::Rack::Logger.class_eval do | |
| def call_with_quiet_assets(env) | |
| previous_level = Rails.logger.level | |
| Rails.logger.level = Logger::ERROR if env['PATH_INFO'] =~ %r{^/assets/} | |
| call_without_quiet_assets(env) | |
| ensure |
| # 1. Add rack-rewrite to your Gemfile and run 'bundle install': | |
| # gem 'rack-rewrite' | |
| # | |
| # 2. Create a file with the contents below in config/initializers/asset_server_middleware.rb | |
| # | |
| # 3. Rename 'YourApp' below | |
| # | |
| # 4. In config/environments/production.rb and config/environments/test.rb, set: | |
| # config.serve_static_assets = true | |
| # config.assets.compile = false |
| #!/bin/sh | |
| # Create this file in the bin/ directory of your | |
| # Rails app. | |
| # Run this script to deploy the app to Heroku. | |
| set -e | |
| # Push changes to Heroku |
| # Copy NaiveHash (end of this file) and rename to RubyHash. | |
| # | |
| # Try using RubyHash in irb/pry and store some data in it | |
| # and notice it has problems with remembering all of your data due | |
| # to RubyHash not handling hash collisions: | |
| # | |
| # require_relative 'ruby_hash' | |
| # h = RubyHash.new | |
| # ('a'..'z').each do |char| | |
| # h[char] = char.upcase |

Expect some false positives here, but hopefully most of these are open source Rails apps that use (or once used) AngularJS.
If you'd like to help update the list, please comment below with any of these apps you discover do not use AngularJS and include my username (@eliotsykes) in your message.
