Flyfoto: Ny tjeneste lar brukerne plassere flyfoto på kartet
Du kan plassere flyfoto på kartet! Flyfoto er fotografier som er tatt i lav høyde fra småfly av landskap, bygninger, natur, bygd og by.

Norway sucks for programmers. It's not what you think.
The country code completely breaks the official YAML 1.1 spec.
NO evaluates into Boolean false...regardless of case.
This can cause cryptic, hard to debug errors; especially in YAML-heavy environments like Kubernetes.

Ring 0 is a highly-privileged state on CPUs.
Negative Ring Levels have even *higher* privilege. You just haven’t heard of them.
For X86, Ring -1 is Hardware Virtualization, Ring -2 is System Management Mode, Ring -3 is Intel ME / AMD PSP.
Arm get's even weirder:

In 1994, a math professor discovered that Intel's Pentium chip sometimes gave the wrong answer when dividing. Fixing this "FDIV" bug cost Intel $475 million. I analyzed the Pentium chip and found the bug. 1/N

I highly recommend the Valhalla talk by @briangoetz.bsky.social at #Devoxx (www.youtube.com/watch?v=eL1y...). Not only because it gives an excellent view on what is coming in Java, but also because Brian clearly explains why it is important to spend much thinking into crucial language features.

I remain skeptical on the notion of modular monoliths. Sure, compartmentalize your code base into cohesive units, loosely coupled. But you hit limits eventually and I just don't see it for large multi-team projects, due the downsides: build complexities (and time), need to align on runtimes and...

how do you all remember every UUID? I find it really hard. so I wrote them all down on every uuid dot com
the list has fast search across all 2^122 values (so you can find your favorites) - hoping to add some social features like "trending UUIDs" soon!

In case you missed it: Bluesky runs on-prem. They migrated off of AWS months back.
So yeah, they DO need to put orders in for servers! (Good luck to the dev team!)

The more I dig into Bluesky, and more importantly the AT Protocol, the more I get that feeling I had when I first got involved with the Kubernetes project.
You can run nearly every part yourself. You can host your own account (PDS server), run your own moderation tooling (labeler), your own feeds, your own clients, and if you insist your own appview (what the app talks to) and relay (shared CDN-like service)
