## 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);

Can't share the complete code because the app's closed source and still in stealth mode, but here's how I'm using React Router and Redux in a large app with server rendering and code splitting on routes.

Server

1. Wildcard Express route configures a Redux store for each request and makes an addReducers() callback available to the getComponents() method of each React Router route. Each route is responsible for adding any Redux reducers it needs when it's loaded. (This isn't really necessary on the

parse & render SVG file with penplot

This might be handy if you have an SVG file that you want to use as, say, a mask for a generative algorithm.

Place the SVG file in the same directory that you are running penplot from.
