Shrinking XenServer VDI VM Disk

XenServer doesn't allow us to do this kinda shrinking so we better recreate the vm copying all the files and recreating grub (boot) files.

1. Prepare the new disk

• Create a Virtual Disk with the final desired size (eg our running vm disk has currently 100G and we want to shrinkg it to 80G so this new disk is gonna be 80G)
• Attach the new disk to the running VM. (For this we'll need to shutdown the vm for a brief moment and power up it back again)
• Under the VM terminal we format the new disk:

fdisk /dev/xvdb #(n, p, ...) DON'T FORGET TO CREATE THE SWAPP PARTITION!!!
mkfs.ext4 /dev/xvdb1

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
