This tutorial is a step by step guide on how to use the javascript QR Code scanner on a webcam video stream in browser. Some people reported experiencing problems including it in their own projets so I guess a tutorial might help others.

Dell OS Recovery Tool Under Linux Mini-HOWTO

Since I was unable to find a specific answer to how can one create a Dell recovery disk from within Linux, I decided to write the steps here.

If you write the CD image directly to the USB drive (or create a new partition and write it there), the laptop will not boot. You need your USB media to be in FAT32 format with the contents of the recovery ISO.

Download the recovery ISO from the support section of Dell website.
Insert a USB Drive with enough capacity to hold the contents of the ISO image.
Format the drive and create a filesystem where $USB_DEVICE is your USB drive (check with fdisk -l, it may be

SchemaSpy is a neat tool to produce visual diagrams for most relational databases.

Here's how to use it to generate schema relationship diagrams for PostgreSQL databases:

Download the jar file from here (the current version is v6.1.0)
Get the PostgreSQL JDBC driver (unless your installed version of java is really old, use the latest JDBC4 jar file)
Run the command against an existing database. For most databases, the schema (-s option) we are interested in is the public one:

	# Place this file in ~/.config/pipewire/pipewire.conf.d/
	# Then reload pipewire sudo systemctl reload --user pipewire.service

	# Use pw-link --input and pw-link --output to find the name of the output and input device.
	# The list will contain one line per port, but you will need the name of the device node.
	# The format is <name of the device node>:<name of the port>.

	# We need to configure two loopback modules. One for the sink and one of the source
