Trying DeepSeek V4 with OpenCode
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.

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 drastically improved image optimization with GoBlog. Responsive images and AVIF support. Using imgproxy.
Part two of this major refactoring will be to find a way to map every image “optimized” using the old implementation to its original image. Just by comparing all files, as there was no database for it.
But until then, enjoy this image from Scotland last year!

As I wrote, I had planned a bikepacking trip covering a total of 224 km. Well, things didn’t quite go as planned.
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 recent years that I really need to try a multi-day trip (just two days for now, lol) with a tent on my own.
Two years ago, I went from Kassel to Braunschweig (215 km) in three days but slept in cozy hotels and reached the day’s destination already by noon. This year will be harder with more than 100 km per day (224 km in total). And just in case something goes wrong, there will always be train stops nearby.
Theoretically, I could also just take the train home overnight and continue my route on the next day. But that would destroy the adventure…
If you have any tips, feel free to tell me. 😊
Bad news about Bitwarden. Apparently their CEO changed, and everything looks like they are preparing for a sale.
Almost two months ago, I switched back to Ubuntu as my primary operating system. While I still have a Windows 11 VM, I never really use it. Ubuntu 26.04 fits all my needs I had since switching to it. While I installed it during the beta, the final LTS version has also been released since then.
It is now almost half a year in my new job, and I think it was the right move. It feels like the time since I started has flown by, as if I had only started yesterday. Every day, I learn something new, both technical and regarding the topic of certificate management, while also contributing what I already know.
I’ve been a Tailscale user for almost five years. Today, I stumbled across NetBird again and largely replaced Tailscale with it.
Now I am 26 + 1 years old. My better half made me this delicious cake and gave me these beautiful flowers and some cool presents!

Upgrading the valves on my bike to Clik valves is a real game changer. Straightforward to use and fixes a few annoying issues with the previous Presta valves (for example, accidentally unscrewing the valve while removing the pump). Another cool thing: there are conversion kits from Schwalbe available for both Presta and Dunlop valves, so I can also upgrade my other bike and my fiancé’s bike. Inflating tires is now a piece of cake!
