Converting libraries to Ember CLI addons

In this guide we will cover two main cases:

• Ember specific library
• vendor library

Ember library

The Ember library will assume that Ember has already ben loaded (higher in the loading order) and thus will assume it has access to the Ember API.

# Use `docker-cleanup -n` for a dry run to see what would be deleted.

Notes:

• Text in [[ ]] are the internal libuv function call.
• Text in {{ }} are the Node functions that are affected.
• Text in ( ) are notes about what is happening.
• While the Windows event loop has minor variations, I don't believe any of those affect Node.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers
