I took advantage of the last sunny, but also 25°C hot day and hiked in the woods. It was so much more pleasant in the forest than out in the sun. The wind could have been a long stronger with that heat. I was completely soaked.

At one point I thought I better grab my camera out of my backpack, so whenever something comes up, I’m ready. But I was too lazy and thought, well, I just wait until there is a nice subject and keep going instead. No joke, ten meters further I came across two squirrels. A red and a brown one, sitting on a tree at just one and three meters height two meters away from me. If I only had unpacked my bloody cam a few seconds ago! I just watched them sit on the tree and then tried to slowly strip my backpack and grad the cam. It was still booting up when they decided it was enough sitting around and climbed higher. What a silly move on my end, damn.

I tried to improvise some Lyse Street View, but felt really uncomfortable to photograph other people’s houses. Somehow my cam produced sooo many blurred shots on the way up still away from the village, it’s unbelievable. I scrapped nearly the entire project. Only very few survived. There were heaps of people on the mountain summit, so I quickly left again.

Looking forward to next week’s rain and temperature drop to 16°C or even 8°C.

@lyse@lyse.isobeef.org It’s probably better for them if they’re shy. 😅 But yeah, if they’re used to humans, they won’t run away so easily. At least the ducks won’t – the rails/moorhens do. đŸ€”

Ahh, I remember those Asperg shots. 😅👍

That whole area with the tunnels and basins is probably some sort of “retention basin” (RegenrĂŒckhaltebecken), with several levels to reduce the flow. There’s almost never a lot of water in there, though. Not sure if this structure just isn’t used anymore or if it’s too dry. There’s also this “pole”, it’s a bit hard to see, though:

Looks like they’re trying to measure the water height (Pegelstand)? The pole is super high and I doubt that any rainfall will ever reach the top of it. đŸ€”

In-reply-to » After a bug in the Open Watcom OS/2 resource compiler has been fixed (imagine that – they still fix bugs related to OS/2! đŸ€ŻđŸ’š), I was able to make some more progress with the OS/2 GUI version of my little disk usage tool. It now has a menu bar and a dialog to open another directory:

There you go, multithreading. đŸ„ł

I tested this in QEMU, which luckily supports throttling disk I/O, so I can make sure that scanning the disk actually takes a while.

(Still boggles my mind a bit. When OS/2 2.x came out, DOS was still the norm for us and I didn’t even know what multithreading was. I really didn’t appreciate this operating system enough back then – only now.)
