	3. Set an AUTH_KEY and AUTH_VALUE and the maintenancePageHtml (optionally)

Allow Docker Container Access to Host's Postgres Database on linux (ubuntu)

You have to do 2 things in order to allow your container to access your host's postgresql database

Make your postgresql listen to an external ip address
Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Make your postgresql listen to an external ip address

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf

Script to quickly scan the S.M.A.R.T. health status of all your hard drive devices in Linux (at least all the ones from /dev/sda to /dev/sdzz). You need smartctl installed on your system for this script to work, and your hard drives need to have S.M.A.R.T. capabilities (they probably do).

	#!/bin/bash

	# install the smartctl package first! (apt-get install smartctl)

Installing HP-107w on Linux (using HP's unified linux driver ULDLINUX_V1.00.39_00.12.zip)

	HP provides a downloadable "driver" for Linux for the HP 107w printer but there are NO reasonable install instructions provided, and following the "obvious" install process did not get the printer working.

	The closest I found to HP install instuctions once I knew more is https://support.hp.com/in-en/document/c05588857

	Since I found this annoying and wasted more time on getting this printer working under Linux, I'm sharing a summary of what did work (on Debian 10).

	1. Download the driver file from https://support.hp.com/us-en/drivers/selfservice/hp-laser-100-printer-series/24494339/model/24494342 from under the "Basic Drivers" menu for when the OS is set to Linux.

	The current version now is: "HP Laser 100 and HP Color Laser 150 Printer series Print Driver V1.00.39:00.12 5.9 MB Mar 20, 2019"
