HOWTO Update Portainer

I’ve set up my Portainer servers slightly differently than the official docs. They map to port 9443 and I map to port 9000. No big whoop, but it will stop me dead.

user@docker:~$ sudo docker stop portainer
portainer
user@docker:~$ sudo docker rm portainer
portainer
user@docker:~$ sudo docker pull portainer/portainer-ce:latest

Further Adventures with Music on Raspberry Pi

I have a Raspberry Pi 3B (not the Plus version) with a HiFiBerry Digi+ DAC HAT attached. This is connected to my old school Sony receiver via TOSLINK fiber. I also have a 10.1″ touchscreen attached.
