Letsencrypt (for WordPress sites)

Note: This setup assumes you are running Ubuntu 16.04 OS with Apache 2.4.23, older versions of Ubuntu (i.e. 14.04) require minor configuration changes in order for this setup to work.

Setup

Follow the install instructions for certbot (letsencrypt's SSL manager) on https://certbot.eff.org/, making sure to select the correct server OS version.

Note: You only need to complete the Install section, then return to this README in order to setup your SSL

gRPC SSL/TLS cert rotation

Generate a couple key pairs:

openssl req -x509 -newkey rsa:2048 -keyout key1.pem -out cert1.pem -days 42 -nodes
openssl req -x509 -newkey rsa:2048 -keyout key2.pem -out cert2.pem -days 42 -nodes
ln -s key1.pem key.pem
ln -s cert1.pem cert.pem

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int
