And a trip to my backyard mountain again. It was very windy, so the 16°C felt even cooler than that. But it will be back in the twenties tomorrow when I visit a mate for a hike, oof.

Farewell ISDN, Ham Radio & Old Network Drivers: Linus Torvalds Merges 138k L.O.C. Removal
Linus Torvalds did it! He merged the pull request to rid the Linux kernel of the old Integrated Services Digital Network (ISDN) subsystem and various other old network drivers largely for PCMCIA era network adapters. This was the code suggested for removal given the recent influx of AI/LLM-generated bug reports against this dated code that likely has no active upstream users remaining… ⌘ Read more

My mate and I hiked some 16-18 kilometers to the Wasserberg. The 22°C sun was beating down hard on us. There were quite a bunch of clouds all around, but none of them casted the tiniest shade on us. Only in the second half we got a little bit luckier in that regard. Still, we were soaked before we even left town. Hardly any breeze.

Unfortunately, I left my camera at home and found it hidden behind the cettle in the kitchen after searching the entire house for some 15 odd minutes. However, a greenfinch paid me a visit this morning and I got it on camera. The sunset was crazy colored, too:

The weathermen just cannot be right with their 20°C today, it must have been more. It was awfully hot, the light breeze was not enough and even absent most of the time. In the shade, it was alright. Other than that, the walk to the dairy farm and back was really beautiful. Very lovely scenery.

Somebody spilled their paintbox at sunset. Unfortunately, I missed to reinsert the SD card into my camera, so I could not take more photos of Azabache and his new mate. They quickly disappeared. He even landed right next to my window, so that would have been a killer shot.

We cleaned up the forest today with the scouts at absolute dream weather. Blue sky, no clouds, 19°C sunshine. In the morning it was still quite chilly and windy, though. We didn’t find anything spectacular, maybe a rubber dinghy, three car tires and a broken ratchet strap are the most outstanding things to me apart from all the general rubbish, cigarettes, glass, wet wipes, etc. Still, a very fun activity. In the end we had bockwurst, grilled cheese and lye buns on the camp fire.

I then went for a quick stroll with my mate. It’s crazy how quickly the clouds moved in, 30-45 minutes tops. There will be rain in an hour. And the coming days only reach half the temps. I’m glad I took advantage of the great spring day. Haven’t seen Azabache yet and with the rain on deck, the odds are against him and me.

@lyse@lyse.isobeef.org AI result ahead, feel free to ignore.

I “asked” the AI at work the same question out of morbid curiousity. It “said” that SQLite converts that integer to floating point internally on overflows and then, when converting back, the x86 instruction cvttsd2si will turn it into 0x8000000000000000, even if the actual floating point value is outside of that range. So, yes, it allegedly actually saturates, as a side effect of the type conversion.

I couldn’t find anything about that automatic conversion in SQLite’s manual, yet, but an experiment looks like it might be true:

sqlite> select typeof(1 << 63);
╭─────────────────╮
│ typeof(1 << 63) │
╞═════════════════╡
│ integer         │
╰─────────────────╯

sqlite> select typeof((1 << 63) - 1);
╭──────────────────────╮
│ typeof((1 << 63) ... │
╞══════════════════════╡
│ real                 │
╰──────────────────────╯

As for cvttsd2si, this source confirms the handling of 0x8000000000000000 on range errors: https://www.felixcloutier.com/x86/cvttsd2si

The following C program also confirms it (run through gdb to see cvttsd2si in action):

<a href="https://we.loveprivacy.club/search?q=%23include">#include</a> <stdint.h>
<a href="https://we.loveprivacy.club/search?q=%23include">#include</a> <stdio.h>

int
main()
{
    int64_t i;
    double d;

    /* -3000 instead of -1, because `double` can’t represent a
     * difference of -1 at this scale. */
    d = -9223372036854775808.0 - 3000;

    i = d;
    printf("%lf, 0x%lx, %ld\n", d, i, i);

    return 0;
}

(Remark about AI usage: Fine, I got an answer and maybe it’s even correct. But doing this completely ruined it for me. It would have been much more satisfying to figure this out myself. I actually suspected some floating point stuff going on here, but instead of verifying this myself I reached for the unethical tool and denied myself a little bit of fun at the weekend. Won’t do that again.)

I called it quits a bit earlier and enjoyed the sunny 19°C blue sky in nature. I just sat an entire hour on a bench (12) near a habitat (07) and enjoyed the sun rays and singing birds around me. When I returned, the batteries were almost drained. The sunset finished them off, so that I could not record Azabache’s concert shortly after. However, I saw that amazing bird this morning and got him on film. Enjoy!

Thank you, @bender@twtxt.net!

My mate and I took advantage of the public holiday and went on a hike. At first, the 14°C and only slight wind weren’t all that terrible, especially since there were only a few clouds. Later, the sun got covered more and more and also the wind picked up. I was really glad that I brought my jacket along. In the beginning I was contemplating about leaving it at home, but then still wore it and stripped it a few minutes into the trip. It was very windy at the summit, so for our second lunch break wearing it was an absolute must. It was a very beautiful trip and I enjoyed my mate’s company.

Finally, Azabache showed up, too. I didn’t bother videoing with all the wind. Didn’t feel like fixing the audio. Maybe tomorrow.

https://lyse.isobeef.org/waldspaziergang-2026-04-03/

Azabache returned just a few minutes later when the sparrow or great/blue tit was gone. Next time I will use a tripod to record the video. Also sorry about the sound, I used all my Audacity skills to remove the noise, but somehow, combining the video and audio track in kdenlive somehow messed up the sound. There’s some horrible sqealing towards the beginning.

The sun was out and tricked everybody to believe it’s nice and warm. However, with the wind, the 11°C felt way colder. Still, super nice out there, I enjoyed it a lot. The quick trip to the dairy farm took me more than double the regular time, because I took close to 400 photos. Oh boy, Lyse is such an idiot!

b) Most of the time, as is. But I’ve tried once: adding in a couple of diced strawberries that have been sitting in granulated sugar for a couple of minutes, until they’d released enough syrup, and I think I might’ve caught a new addiction on top of the original one.
