I write about my technical adventures, such as developing my own blogging software, and other topics that interest me as a software developer. However, I also enjoy documenting my life, from bike tours to everyday moments that I want to share.

Some time ago I posted about my experience blocking one country and some ASNs directly via iptables from my mail server. It seems like there’s an even better source of IPs and networks to block. The Spamhaus “Don’t Route Or Peer Lists...
Why spend 80 € on a simple cap? Because it fits my big head perfectly, is very comfortable, offers good sun protection, is high-quality, and also keeps me from being blinded by the sun. With this cap and my hat, my collection of summer...
I am currently in the process of migrating to a new mailserver setup that is integrated into my normal hosting setup on a new VPS at netcup. This time, the setup is based on the Docker images and configuration from a project called...
We recently had a test photo shooting with our wedding photographer. The photos that came out of this session are beautiful. I took the chance to finally update my profile picture (the last one was from 2022) with a cropped version of...
For the regular planning workshop at work (my second since I started), I have to be in Schwäbisch Hall from Monday to Wednesday. As train tickets are cheaper on Saturday than on Sunday and I was eager to explore the city anyway, I...
As I told you, I recently switched to mainly using NetBird instead of Tailscale. NetBird released their “Bring your own proxy” functionality on the cloud-hosted version today. That gave me the perfect reason to finally try a VPS at...
I have a couple of restic backup containers running across my servers, all based on the resticker image. It’s a basic part of every server configuration I use. Backups are executed on cron schedules. But until today, I had no visibility...
I took my bike out for a short ride again yesterday. The last days it was rainy and stormy, but yesterday, there was a bit of sun again. Also wind, but I took it relaxed. Nature also really calmed me down. I haven’t really realized...
Many news sites, including a few German ones, are now trying to get you to add them as a preferred source on Google. This can be annoying. Why should I do this? And why do you try to remind me on every visit? And why do you even assume I...
And just like that, another month has flown by. Time for my usual look back. The month started with my longest single-day bike tour ever: 136 km from Braunschweig to Gifhorn, Celle, and back. It was pretty exhausting, but that didn’t...
Regarding my last post: While I spent plenty of thoughts on the whole implementation, most of the coding work was actually done by DeepSeek V4 Flash and Pro, and I just supervised and criticized it. While I mainly used Amp Free in the...
The moment when you finally deploy a change on which you worked over some days, trying to think through every possible use case and scenario, and you just hope it’s working flawlessly. 🙏 Such a moment was just now for me! I finally and...
As I wrote, I had planned a bikepacking trip covering a total of 224 km. Well, things didn’t quite go as planned. Shortly after my post, I changed the route due to a lack of good camping options along the way. I read some bad reviews...
I planned a bikepacking trip for the coming weekend, but I am not really sure if I overestimate my power, if I will eat enough, and if I will be able to put up the tent on my own. 😅 I watched so many YouTube videos on bikepacking in the...
Bad news about Bitwarden. Apparently their CEO changed, and everything looks like they are preparing for a sale. Bitwarden has also stopped listing “Inclusion” and “Transparency” as tentpole values on its careers page. On his LinkedIn...
