Bonfire: Diff Two Arrays - I had stuck here and finally figured out, pick up the right solution!

ruby Colon access operator explained with example
# Double Colon (::) is namespace resolution. It can also call Class Level Constants. So when you do this:
MyModule::MyClass::MySubClass
MyModule::MyClass::MySubClass::CONSTANT
# it is calling the name space of:
module MyModule
class MyClass
class MySubClass
CONSTANT = 'test'

Start Ruby on Rails and Ruby Sinatra app on Cloud9!

Run Ruby on Rails/Sinatra app on Cloud9 IDE

##Problem:

I spent hours trying to run up a Ruby web server using Sinatra on Cloud 9. The cloud9 IDE instructions on the Output screen say:

Your code is running at http://<project-name>.<username>.c9.io'.
Important: use 'ruby app.rb -p $PORT -b $IP' to run your server apps!

In fact, these are the instructions for a Rails application, and the -b switch is invalid for Sinatra applications, which I discovered when using the Terminal window!!!
