                Minimal DevStack in a VirtualBox VM for Keystone
              
          
    Minimal DevStack VirtualBox setup

This is a very concise quickstart guide to setup an OpenStack DevStack limited to Keystone in a VirtualBox VM using Ubuntu Server LTS as the guest operating system.
By limiting the DevStack to primarily deploy Keystone only, installation is quick and the machine does not take up much resources.
As the time of writing it uses up about 11 GB of disk space and 1 GB of RAM running Keystone.
This is meant for testing authentication and IDM-related things with OpenStack Keystone while disregarding other components.
It can easily be extended by further components by adjusting the local.conf accordingly.

                Discord lagging during long calls on Linux
              
          
    My discord was lagging increasingly during long calls on my Manjaro installation. I searched a bit on the Wiki but the fix shared there didn't work for.
What worked for me is this answer on the Discord support forum, that I will detail a bit here. Start by moving to the right folder:
cd ~/.config/discord/<your_version>/modules/discord_desktop_core

Then, depending on whether you are a javascript developer or not, you may need to install the npm package of your distribution.
On Arch/Manjaro, yay -S npm will do. Once this is done, unpack the core.asar file with
npx asar extract core.asar core
