Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus

What

A lot of times you are developing a web application on your own laptop or home computer and would like to demo it to the public. Most of those times you are behind a router/firewall and you don't have a public IP address. Instead of configuring routers (often not possible), this solution gives you a public URL that's reverse tunnelled via ssh to your laptop.

Because of the relaxation of the sshd setup, it's best used on a dedicated virtual machine just for this (an Amazon micro instance for example).

	* tiny_IRremote
	* Version 0.2 July, 2016
	* Christian D'Abrera
	* Fixed what was originally rather broken code from http://www.gammon.com.au/Arduino/
	* ...itself based on work by Ken Shirriff.
	*
	* This code was tested for both sending and receiving IR on an ATtiny85 DIP-8 chip.
	* IMPORTANT: IRsend only works from PB4 ("pin 4" according to Arduino). You will need to
	* determine which physical pin this corresponds to for your chip, and connect your transmitter
