Ich bin kein großer Fan davon, im Internet ge’tracked zu werden. Bisher dachte ich, Cookies löschen und Pi-Hole wären schon eine recht gute Lösung. — Dass aber noch direkt am Telefonanbieter auch noch ein Unternehmen steckt und cookieless track’ed, hat mich dann doch sehr überrascht.

How to migrate Gmail to another Provider without Breaking the Mail History
This is a practical how-to on moving email from Gmail to another provider.
The main challenge is Gmail’s label system: one email can have multiple labels and all mails also appear in “All Mail”. Most other providers use folders instead, where an email can only exist in one place. If you migrate without taking this into account, you will most likely end up with duplicated mails or a messy folder structure.

How to fix: Windows automatically goes to Dark Mode (after Oct 16th 2025)
Problem: Windows automatically goes to dark or light mode, no matter what is set in the system settings. Even worse: when you change the mode in the system settings, windows switches back after a few seconds.

How to get RSS feeds for Releases / Tags on GitHub
With growing amount of running selfhosted services, it becomes a bit tedious to keep track of new software releases.
Luckily, GitHub offers RSS Streams for Releases and Tags (and some more). By adding those streams to the RSS reader, I see it in my RSS feeds when I have to take action.

Farewell to my 11.5-Year-Old RaspberryPi Weather Station
Eleven and a half years ago, I built my first RaspberryPi weather station using sensors from Tinkerforge. Today, I shut it down for good. Not because it failed — but because its job is done. It’s been replaced by a Netatmo setup, and unfortunately, I don’t need it anymore. But admitting that a project’s lifespan is over always takes some effort — well, to me at least.

How to get the ‘<‘, ‘>’ and ‘|’ keys on a Dell Latitude 5300
Since a while I am using a refurbed Dell Latitude 5300. I’m pretty happy with it. Just recently I was doing some stuff via SSH on my RaspberryPIs when I noticed that the Dell’s keyboard does not contain the ‘<‘ key. Not a big deal usually – just Linux Shell working is quite uncool without the ‘>’ and the pipe ‘|’ characters.

How to solve weird Docker Errors on Ubuntu
After being so happy about all the services that I brought up last weekend, I forgot to do one thing: rebooting. Today I rebooted for some reason and the containers didn’t came up again.

How to Use a Lenovo ThinkCentre M910q as a Powerful Home Server
As an IT enthusiast, I’ve long been (and still are!) a fan of the #RaspberryPi mini computers. My main Pi already runs multiple services like #PiHole, #Navidrome and #Jellyfin – which often pushes it near its limits. Well, recently I found myself wanting to add even more services to my local network. Unfortunately, my NAS can’t host Docker containers, so expanding compute power became necessary.

How to batch migrate Repos from Bitbucket to Codeberg
When I was browsing through my code archive, I noticed that I was missing some projects and wondered where I had left them after my recent re-install. Just then I noticed that I still had some private repos at Bitbucket. As I just needed a place to back up the code, I decided that I could move it to Codeberg.
Codeberg describes itself as “[…] a non-profit, community-led effort that provides Git hosting and other services for free and open source projects.”. Codeberg e.V. itself is a registered non-profit association based in Berlin, Germany.

How to check the Email Security Level of your Provider
If you’ve ever wondered which security protocols your email-provider supports, there is an easy way that I found via Mastodon:
The European Commision provides My Email Communications Security Assessment (MECSA) (https://mecsa.jrc.ec.europa.eu/) with which you can quickly check, which of the protocols your provider supports (StartTLS, x509 Ceerts, SPF, DKIM, DMARC, DANE, DNSSEC).
