Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

Use ESM yourself. (preferred)
Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
Stay on the existing version of the package until you can move to ESM.

Wireguard and iptables restrictions for multiple users

If you don't know what Wireguard is, well, you should. It's fast, easy to setup and highly configurable. We will configure Wireguard for multiple users with various restrictions using iptables.

Assumptions

This should fit most setups (not mine though 😉)

Compiling and installing `vlc` with Decklink support on Ubuntu 18.04 Server

Note that there are API changes in BlackMagic Design (BMD) SDK 11 onwards; so as of vlc-3.0.8, compile it with BMD SDK 10.11.4.
Also note that you need to disable UEFI Secure Boot in order to install BMD driver successfully.
Additional note: VLC may have stuttering sound when playing through DeckLink which is caused by commit 576b4da8d674d8a98dd493e9b343f1875efde047

TL;DR

ffmpeg

Converting Audio into Different Formats / Sample Rates

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

You can get the list of installed codecs with:
