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

Multiple MySQL versions on MacOS with Homebrew

At the time of writing (december 2018), there aren’t any up-to-date and easy to apply guides on how to switch between different MySQL version on a Mac using Homebrew . Or at least, I didn’t find any.

So I picked up a few things here and there and finally managed to connect all the pieces of the puzzle. I hope this guide can help you and the future me. If anyone knows of a better way to accomplish this, I do hope they will share their insight :)

The basic idea here is that you need to install all MySQL versions one at a time and assign each its own data directory.

I am using Homebrew 1.8.5. (brew -v)
