This is a basic implementation of the Atari Pong game, but it's missing a few things intentionally and they're left as further exploration for the reader.

On OS/X Sierra, after recently running a brew update I started receiving the error message Sorry, you can't use byebug without Readline when trying to run some rake tasks in my ruby project folder. I observed this in projects and gems that include byebug or pry in their Gemfile or gem.spec. I've found in my googling that many begin encountering this error message after running a brew update but there are other triggering conditions as well.

WARN: Unresolved specs during Gem::Specification.reset:

Please report a bug if this causes problems.
Sorry, you can't use byebug without Readline. To solve this, you need to

Sinatra Flash is an awesome gem that allows you to pop up little messages alerting your users of important things, via some simple code in your server.rb file. This is very useful for things like displaying error messages if the user has filled out a form wrong, or displaying "success" messages if the user did something successfully like sign in, sign out, or submit a form.
This also gives you a great chance to implement Foundation's beautiful alerts. Here's how to set it up!
gem install sinatra-flash in your terminal.require 'sinatra/flash'
| # Basic example | |
| siege -t60s -c20 -d10 'http://robertomurray.co.uk/' | |
| # Basic auth; | |
| auth=$(echo -n 'username:password' | openssl base64) | |
| siege -t60s -c20 -d10 --header="Authorization:Basic $auth" 'https://staging.a-hostname.co.uk/' |
Command Line
pry -r ./config/app_init_file.rb - load your app into a pry session (look at the file loaded by config.ru)pry -r ./config/environment.rb - load your rails into a pry sessionDebugger
