Botteling – Pepermeibock
Beer at last taken out of the cooling unit. Cooling temperature was not perfect, need to fix some things in my brewing computer 🙂
Above the brewfather app. The transition from Brouwhulp to brewfather was big, but it is a great online tool, with perfect integration of tools like ispindel, or DIY tools!

2022 Lab upgrades, old servers removed
A fresh start
Add packages to a pre-existing docker image
A little test building a custom docker image, for a friend.
Q: I have a Node-red docker, but without ffmpeg binary
Using below code, i’ve added a overlay with ffmpeg.
Podman command’s should be working for docker command also.
(Note: When adding multiple packages OR other commands, try to use a single commandline, Every RUN command adds a overlay.
mkdir noderedbuild
cd noderedbuild
vi DockerfileFROM nodered/node-red
LABEL description="Custom Nodered Build"
MAINTAINER haanstoot <fash@fash.nu>
USER root
RUN apk add --no-cache ffmpeg
EXPOSE 1880Below builds a local image named nodered:v1
NOTE: docker run command may be incomplete for Node-Red, this was just a example to add packages
podman build -t nodered:v1 .
podman images

LS120 app android
May 2020 i’ve bought a Youless LS120, to monitor my electricity and gas, today i found out there is a android app .. Duh 🙂
Audio switcher
Doing my work from home via Jitsi (Jabra headset) and Listening to music on my speakers. Sometimes i want to switch output. For example spotify on my headset.
Using below code, i can easily switch between output sinks.
#!/bin/bash
if [ -z "$1" ]; then
echo "DEVICE"
pactl list sinks | egrep "^Sink|Description" | sed 'N;s/\n/,/' |sed -e 's/\t/ /g' | cut -f2,5- -d" "
echo "APPLICATIONS"
pactl list sink-inputs | egrep -ie "^Sink|application.name" | grep -v "\-application-name" | sed 'N;s/\n/,/' | sed -e 's/\t/ /g' | sed -e 's/ / /g' | cut -f3,6- -d" "
echo "Usage: $0 APPID DEVICEID" >&2
exit 1
fi
pactl move-sink-input $1 $2It shows output devices, and applications which are using audio sinks.
Just match them up.
