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);

Raspberry Pi setup

Just wanted a quick start guide for myself so that I wouldn't have to keep rooting through Google to remember all this stuff. Hopefully it helps other people.

If you had other ideas or suggestions please leave a comment.

Useful things to own before you buy a Pi

The first time I bought a Pi I was enormously frustrated with myself because I didn't own all of this stuff. Kept having to order things off of Amazon and wait to get started... very irritating. This is all good stuff to have laying around anyway:

var app = require(process.cwd() + '/app');
var winston = require('winston');
var _ = require('lodash');

// Set up logger
var customColors = {
  trace: 'white',
  debug: 'green',
  info: 'green',
  warn: 'yellow',

lsbom -f -l -s -pf /var/db/receipts/org.nodejs.pkg.bom | while read f; do  sudo rm /usr/local/${f}; done
sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*

# To recap, the best way (I've found) to completely uninstall node + npm is to do the following:

# go to /usr/local/lib and delete any node and node_modules
cd /usr/local/lib
sudo rm -rf node*
