Create DNS-over-TLS bridge with Pi-hole, unbound and stubby on Ubuntu Server

Few months ago, I've made a similar work but I wanted something a little more easier to manage. Please have a look at here for my previous work.

This time, I'm gonna do pretty much the same thing but using Pi-hole as base then modify it to include unbound and stubby.

This way, I can use the power of Pi-hole with some additional security layers:

Recursive DNS check (unbound)
DNS-over-TLS (stubby)

Backup/Image

Make sure the if value is correct! If doing this over SSH then open a TMUX session first... or else...

dd if=/dev/YOUR-DEVICE conv=sync,noerror bs=64K | gzip -c  > /home/portaj/macbook.img.gz

NOTE: You might not want to compress the image. It just means you have to uncompress it later to mount it. If you're planning to access the data soon, or frequently, don't compress it.

Saving a copy of the drive geometry

Save it in the same directory as the compressed image so later on if you decide you want to mount or extract data from the image you can see the partition structure without having to decompress the whole image. There might be some other ways to mount a compressed image.

Building and using mesa for development and testing

This explains how to build mesa from source, and how to use the custom built mesa to run some apps and games, without needing to replace the mesa libraries that your operating system runs on.

Let's assume that you are using an x86_64 system.

	10-Bit H.264

	For all those who haven’t heard of it already, here’s a quick rundown about the
	newest trend in making our encodes unplayable on even more systems: So-called
	high-bit-depth H.264. So, why another format, and what makes this stuff
	different from what you know already?

	First off: What is bit depth?
	In short, bit depth is the level of precision that’s available for storing color
	information. The encodes you’re used to have a precision of 8 bits (256 levels)
