The scale of modern display tech is absurd.
That's a MicroLED on the right: 15×30 micrometers.
Smaller than a dust particle.
Thousands fit where one standard LED used to go.
Wild what's possible with modern manufacturing

Sad to see it go, but so much respect for the maintainers who poured years of work into it.

I just wrote my first blog/Medium post. I know I’m at least five years late, but I’d really appreciate it if someone could take a look, critique it, and maybe suggest ideas for future posts

Bought 6x Server with AMD Ryzen 9 7950X3D CPUs, Boostclock is 5.7ghz. They are so fast compared to random cloud vm server cpus (2-2.5ghz) . Should have switched sooner

I'm playing org Mode again
I still can't estimate the number of hours I will waste

I still don't fully understand business networking events

that can't be the purpose of it

I'm at the point again where I have a kubernetes operator that automatically creates resources in keycloak
This time in a tenth of the time as last time 😁

I already regret switching from bare metal / vms to a managed kubernetes service from a big cloud provider
If you know how to deploy applications on Linux/containers/self managed k8s you should stick with it
I will also switch back in the next few months

The animations here feel a bit slow
Is this normal?

Another hackathon
and again I didn't get anywhere near what I wanted to do
