using Ansible command line:

ansible-playbook --connection=local 127.0.0.1 playbook.yml

using inventory:

127.0.0.1 ansible_connection=local

A monad is a fancy word for a generic type of the form MyMonad<T> (a generic type of arity 1).

A monad is special because it adds 'special powers' to the T that it wraps. These 'special powers' won't sound very special to an imperative programmer, so you have to squint to see them but bear with me.

IEnumerable<T> is a monad that gives values of type T the special power of nondeterminism, or the ability to 'be' multiple values at once.
Nullable<T> is a monad that gives values of type T the special power of nullability, or the ability to be absent.
Task<T> is a monad that gives values of type T the special power of asynchronicity, or the ability to be used before they are computed.

The trick with monads comes when you want to play with the T values, because they are inside another type. C# introduced language changes to make dealing with values inside these monads easier:

Typing vagrant from the command line will display a list of all available commands.

Be sure that you are in the same directory as the Vagrantfile when running these commands!

Creating a VM

vagrant init -- Initialize Vagrant with a Vagrantfile and ./.vagrant directory, using no specified base image. Before you can do vagrant up, you'll need to specify a base image in the Vagrantfile.
vagrant init <boxpath> -- Initialize Vagrant with a specific box. To find a box, go to the public Vagrant box catalog. When you find one you like, just replace it's name with boxpath. For example, vagrant init ubuntu/trusty64.

Starting a VM

vagrant up -- starts vagrant environment (also provisions only on the FIRST vagrant up)
