Jeff was around today, and so we went for a ride at 9. It's a beautiful day, not too cold, either. The air is still full of Sahara dust, so the light is different.

The whole day looked somewhat strange. No clouds, but not sunny, either, and the sky wasn't blue. Around lunch, I thought it all reminded me of some of the photos from Mars rovers.
Turns out we have a lot of dust in the air from the Sahara over in Africa.
Well, that explains it.

A thing I equally like and hate about ADHD is this thing where I come to some conclusion that I think is important, tell somebody in my surroundings about it, and they're like "didn't you say that 2 weeks ago?"
I shall call it "repeat epiphanies" from now on.
Good, bcs having an epiphany feels good. Bad, bcs the realisation that I forget them again is sad and disheartening.

Can I ask a question re Jetpack Compose Navigation 3, please?
I am using a `NavDisplay` inside a "global" `Scaffold` with a `TopAppBar`, because that allows me to have an app-wide menu.
But I would also like the `TopAppBar` to display a different title depending on the navigation backstack.
How do I do that?

Very clear sky, so we were able to see Mont Blanc from the Fourvière hill in Lyon.

Oh, forgot to post my Sunday ride!
I woke up at 8.30, decided to turn around just for _one_ minute, woke up again at 11, then decided that with the kids at mine, it was too late for a ride. Rats.
They left at 6, so I took the eeb and left, too.
It was pretty dark when I arrived at the bottom of the Blauen.

On the way to town this morning, the Sun was just coming up on my right, I noticed a smudge of red on the left, like a red pillar.
A second later, it started to look like an arc! I turned my head and saw a second arc further south, also red.
That's when I started thinking it looked like a rainbow, just red.
30s later, the arc was clearly visible.
