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);

Synopsis

At the top of the file there should be a short introduction and/ or overview that explains what the project is. This description should match descriptions added for package managers (Gemspec, package.json, etc.)

Code Example

Show what the library does as concisely as possible, developers should be able to figure out how your project solves their problem by looking at the code example. Make sure the API you are showing off is obvious, and that your code is short and concise.

Motivation

The script below is triggered every day from my Mac. I use Hazel to move the tar.gz to an external hard disk once it's finished. This happens every day without me noticing. You can exclude folders if you want to. You probably want to exclude giant cache folders.

You should have a similar script.

	// iOS6 suffers from a bug that kills timers that are created while a page is scrolling.
	// This library fixes that problem by recreating timers after scrolling finishes (with interval correction).
	// This code is released in the public domain. Do with it what you want, without limitations. I do not promise
