Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

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

	Installing on a newer PC with GFI requires a little differen't partitioning. When you open up gparted or your favorite command line partition tool, you need to do the following:

	Create a partition scheme that is GPT. Then create the first partition as FAT32 and make it 200 mb or larger, set the flags to boot and esp. Then create your main partition and if you want, a home partition and swap partition.

	Next step is to partition the main os partition:
	mkfs.ext4 -L nixos /dev/sda1

	Mount the partition:
	mount /dev/disk/by-label/nixos /mnt

	# Assuming an Ubuntu Docker image
	$ docker run -it <image> /bin/bash
