How to setup Plex with Sonarr, Radarr, Jackett, Overseerr and qBitTorrent using Docker

Before continuing: This guide is currently outdated but I'm working on a new one with upgrading steps included. I'll link it here once it's finished :)

This is a guide that will show you how to setup Plex Media Server with Sonarr, Radarr, Jackett, Overseerr and qBitTorrent with Docker. It is written for Ubuntu 20.04 but should work on other Linux distributions as well (considering supported distributions by Docker). It is also written for people who have some experience with Linux and Docker. If you are new to Docker, I recommend you to read the Docker documentation, and if you are new to Linux, I recommend you to read the Ubuntu documentation.

Now, let's get started!

Please note: This guide was written without considering hardlinking for Sonarr/Radarr. If you want to use hardlinking refer to #Hardlinking

Boolean Algebra in a nutshell for JS/TS programmers

There are a lot of strategies that you will hear about in the Javascript community for keeping your conditionals from becoming a tangled mess. This isn't like them. This is someting different. MATH! Boolean Algebra to be exact. I use it all the time to simplify complex conditionals. There are two things that you need to know: de Morgan's Theorem, and Karnaugh (pronounced CAR-no) Maps. (Don't worry, there is no test)

de Morgan's Theorem

De Morgan's Theorem is great distributing nots (!), and for when you want to convert an && to an ||, or back. This is it:

 !(A && B) = !A || !B

Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work (NOT FOR QMK-BASED BOARDS)

Older Keychron keyboards (those not based on QMK) use the hid_apple driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.

The Rules of React

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.

What Functions Are "Pure"?

A number of methods in React are assumed to be "pure".

On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.
