Raspberry Pi from SD to USB

How to switch over from SD-card to USB-attached device (USB thumbstick, USB enclosed SSD or HDD, etc.) to have more durable storage option.

Steps

Connect USB device to your RPI
Make sure USB device visible by the system

Think twice before abandoning X11. Wayland breaks everything!

tl;dr: Wayland is not "the future", it is merely an incompatible alternative to the established standard with a different set of priorities and goals.

Wayland breaks everything! It is binary incompatible, provides no clear transition path with 1:1 replacements for everything in X11, and is even philosophically incompatible with X11. Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating e

Setup face recognition authentication on ArchLinux and KDE Plasma using howdy

This is surprisingly easy...basically following Arch Wiki:

After some investigation, here is step by step and preferences

Install `howdy`

Connecting to a Raspberry Pi through a VPS using a reverse SSH tunnel

SSH (Secure Shell) to a host existing in an internal network through a reverse-tunneled SSH connection to an externally accessible VPS (Virtual Private Server). This setup is described where the internal host is a Raspberry Pi, but can be generalized for any host on the internal network that runs an OpenSSH server.

	- BIOS of host machine also needs to be configured to allow hardware virtualization
	- Windows 10 Pro or otherwise is needed; Windows 10 Home Edition CANNOT get WSL
	- This gist WSLv2, but can use WSLv1 instead. I needed v1 as I run Windows 10 in a VM in Virtualbox.
	- WSLv2 has been giving me problems in Virtualbox 6.1, but WSLv1 works properly.
	- vbox has issues with the GUI settings when it comes to nested virtualization on certain systems,
	so run the following if needing to give a VM this enabled setting:

	VBoxManage modifyvm <vm-name> --nested-hw-virt on
