Dexed is a FM Synth Plugin (https://github.com/asb2m10/dexed) offering a standalone version you can download from their git releases. Executing their pre-compiled binary on my Linux machine I got the following error:
~/Downloads/dexed-0.9.4.lnx % ./Dexed  29833 illegal hardware instruction (core dumped) ./Dexed
Building Dexed from source solved the problem :)
This is a quick guide how to build it your self using docker.

To use the volume keys on your keyboard on linux or with a raspberry pi in particular, you can use the triggerhappy package, which comes pre-installed with raspbian.
The trigger happy config has to be saved at `/etc/triggerhappy/triggers.d/*.conf. We first specify the key, followed by the corresponding action to take.
KEY_VOLUMEUP 1 /usr/bin/amixer -M set PCM 5%+ KEY_VOLUMEUP 2 /usr/bin/amixer -M set PCM 5%+ KEY_VOLUMEDOWN 1 /usr/bin/amixer -M set PCM 5%- KEY_VOLUMEDOWN 2 /usr/bin/amixer -M set PCM 5%- KEY_MIN_INTERESTING 1 /usr/bin/amixer set PCM 1+ toggle

No matter the settings in
/boot/config.txt i always got to a signal during boot, but "no signal" when the desktop was supposed to show up, or the monitor detected the wrong resolution ([email protected]).

There are a couple of good tutorials on how to set up your own OpenVPN server (e.g. here, here, or here). To route all traffic through VPN, you need to set up some iptables on the server, which is also well documented. This post is about a problem i encountered that was not described anywhere: on every reboot of your machine the iptables are reset.
To solve this, you want to save your iptables to a file and load them on the startup of the network interfaces.
Setup iptables as usual:
iptables -t nat -A POSTROUTING -s 10.8 …
Users of the lpf-spotify-client on fedora do not automatically have the media keys bound to the client. You can do that by sending dbus commands to the spotify process (dbus is already installed as a dependency of systemd)
Just bind the following commands to your media keys in system settings.
dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause
dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Stop
dbus-send --print-reply --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Next
