• when adding new entries to .env for a docker-compose.yml .. make sure you put them also into the environment: section of your service to actually make use of them. Was searching for quite some time why my Minio didn’t properly made use of Prometheus …
• Set up a playground for Homeassistent and ESPhome. Nice thing about ESPhome is, that it’s got readymade firmware for many microcontroller boards and one can just flash them via the Browser.
• Mattermost has finally release their Mobile app in Version 2.x. Most notable feature is the support for multiple Mattermost servers. This is very important as the self-hosted Slack-alternative grew rather popular the last years and the likelihood that you have to use multiple is increasing.
• tried out the new 7.51 firmware from the FritzLab for my ancient Fritz!Box 7490. Seems to have wifi issues with my setup. So I switched back after about 1 day

Sport

• on track with running 2x per week
• trying to get more rowing done if time permits
• swimming in the lake at 1.5ºC water temp on Sunday

Sightseeing

• visited the Museum Barberini in Postdam. Nice collection of famous impressionist pictures
• stunning that most of the pictures didn’t even had protective glas. You could really see all the great details of the pictures. There were watch guards in every room though.
• we used the VIP treatment and were able to get right into museum with the car.

• on thursday I had to pick up my daughter somewhere in Neukölln. The usual route was blocked due to some blockage on the Ringbahn so I had to travel the U1 and U8 route in Neukölln. Quite a different world from Friedrichshain. There are so many small shops of different purposes. I wonder how they thrive at this size in this economy.

Product Management

• one very important question for product managers to decide the priority of a certain feature is: “Whats the business value of this feature?”
• It can be further specified with questions like “How exactly does this make our product better?”, “Which problem does it solve?”
• If you don’t have a very clear answer to these questions, then you’ll have a problem with the delivery of that feature.

Books

• finished reading “The Dark forest” and started the third volume of the trilogy “Death’s end”
• This one is on my wishlist now: Kat Menschiks und des Psychiaters Doctor medicinae Jakob Hein Illustrirtes Kompendium der psychoaktiven Pflanzen

Weather

• finally some snow. at least for one day
