How I Got Node.js Talking on EC2's Port 80

The Problem

Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.)

The temptingly easy but ultimately wrong solution:

Alter the port the script talks to from 8000 to 80:

}).listen(80);

A list of free email provider domains. Some of these are probably not around anymore. I've combined a dozen lists from around the web. Current "major providers" should all be in here as of the date this is created.

Installing node and npm on a Django AWS ElasticBeanstalk
# This specifies the deployment process on AWS ElasticBeanstalk for a Django app using npm and Postgres.
#
# The target environment should have access to a Postgres Database through environment variables.
# The environment can be setup using `eb create --database.engine=postgres`
# The necessary environment variables to access the database will be automatically defined on the
# instances of that environment.
#
# In addition, the target environment should define environment variables (django secret key ...).
# They can be manually defined using the AWS ElasticBeanstalk interface on the web.
# They can also be specified when creating the environment from command line, for example:
