The 26°C humidity was through the roof and we just barely escaped the thunderstorm on our stroll. Only the adjacent rain hit us hard. Black clouds caught up on us and we decided to take cover at a barn. Not even a minute later it started to rain cats and dogs for ten minutes straight. Holy crap, that was cool to watch. :-) Also, the smell of rain was just beautiful.

We then decided to continue our return in the light drizzle. But it then got much heavier again and we got completely soaked. With the wet t-shirt and the wind it actually felt rather cold. I anticipated to get rained on, so I left my camera at home. Plenty of paths turned into brook landscapes, several centimeter deep creeks ran down the hilly trails. Quite fascinating. :-)

The sunset a few minutes ago wasn’t too bad:

Oh, this is interesting! Reading the Crafting Interpreters book, I came across a table of exit codes in FreeBSD.

I didn’t know that a command line usage error is supposed to report exit code 64. In the past I either simply exited with 1 or sometimes each exit statement got its own dedicated number. The latter came in useful for debugging shell scripts. I exactly knew which branch was executed. That was handy when the error messages were similar or even the same.

I was always wondering if there is some kind of a standard, but I never did my reasearch. Looking at other people’s code, it always seemed to me that everybody just did wantever they wanted to in regards to exit codes. I just looked up what else is out there and systemd also defines heaps of errors. It even references the FreeBSD one and links to the Linux Standard Base specification, too. Cool, cool!

Do you guys know of these conventions and make use of them?

Hell yeah! Thanks to @movq@www.uninformativ.de’s asciiworld I was able to to just spot the ISS. And the coolest thing ever was a small shooting star that came down right in front of the ISS when it just passed Ursa Major! :-) Holy cow, how fucking cool is that!? Mega awesome! Thanks mate for this brilliant program! Absolutely worth every minute you spent on it! Thank you sooo much! :-) I’m super hyped right now. I really gotta go to bed now, though.

In comparison to the last times, today’s firefly hunt was rather mediocre. Just 14 specimens. However, even ten females sitting in the bushes and only four flying males. Certainly a female record, thus, can’t complain. I also came across five, six toads. And I heard a deer escaping into the woods. Couldn’t see anything, but it sounded like hoofs on the asphalt in front of me.

The rain finally got me, it was forecast to arrive later. Oh well.

Loud music from town blasted uphill into the forest. And fireworks reverbed with loud bangs over the hills in the middle of nature, holy crap!

Went on a great 20km hike to the Wäscherschloss (lit. Launderer Castle) with my mate. Unfortunately, the castle was closed (only opens on Sundays and public holidays), so we had to peek under the door with our cameras.

Wäscherschloss

Sunny and a few clouds, very windy, my hat blew off a few times, perfect 20°C hiking weather. Could have been a few degrees less, though. We walked through some beautiful scenery, especially when it is lit up by the sun. Really gorgeous views and paths. I should go over there more often. Last time was almost exactly two years ago.

The one steep foot path in the forest had 60cm deep canyons from the flood two weeks ago. Absolutely crazy! The burried post cable caution tape even was revealed. That path didn’t look like a path anymore at all.

At home I had to remove a tick. Those fucking bastards!

In-reply-to » Couple of days ago I made a small patch to yarnd (this pod effectively runs main) that filtered out "inactive users", hard-coded to be LastSeenAt > 90 days and not bother fetching feeds for anything they follow. This has had a dramatic impact on the resources used by this pod (twtxt.net) -- See screenshtos.

Duplicates everywhere! Sigh.

These 24°C were brutal. The cow in 03 was standing in the bog, not sure why she liked this brackish water. It sounded “tchlk, schlk” when she moved around in that mud (what do you call that?). Some of these canyons, like 14, are over 30cm deep. Wow. In 15 at a height of two meters, a torn rag hangs in the tree in the creek bed. It’s crazy to see how high the flood came in 16 with all the washed up stuff in the hedge.

Between Friday 8am and Monday 8am it rained 161 liters per square meter. Our weatherman in town measured alone 40 liters on Sunday between 22:30 and 23:45. On average we get 92 liters in total in the entire May and 96 liters in June. It was a lot, but i didn’t think it was actually that much. Wow!

Down in the town a lot of houses have been flooded. The municipality provided containers for all the garbage. From what I read it was the smaller creek, not the larger river that went absolutely berserk.

I’m on a hill, far away from the river, but with all that rain and soaked ground the water finally came into the basement where the cables enter the house over night. Luckily, just 15 mm high, so it didn’t jump the doorsill into other rooms. And it was all clear, no muddy mess, all nicely filtered through the earth, gravel and sand. My shop vac is also designed to work as a wet vacuum cleaner, so that was really helpful.

Hmm, when I join all my eight incremental database schema changes into just a single one (basically drop support for migration of old databases), my test execution time drops from about 1:10 minutes to just 33 seconds. I might consider doing exactly that. I’m the only one who runs that software anyway.

Just haven’t figured out where exactly the speedup comes from. I suspected that the column recreation is kind of expensive, but it doesn’t really appear to that obvious. More testing is needed.

Regarding https://www.uninformativ.de/blog/postings/2024-05-23/0/POSTING-en.html: I remember using Star $Something back in the days. I don’t remember the exact name anymore and none of the screenshots of StarOffice look familiar. Hmm. I have a green UI in mind. Not sure if I completely hallucinate it or whether that was actually the case. It was a commercial software, not freeware, we had to buy it, I think.

My first LaTeX distribution was MiKTeX with – if I remember correctly – the TeXNicCenter. A bit later on Linux I used Kile as my LaTeX editor. LaTeX produces the worst error messages I’ve ever come across. So compile early and often. But the results are amazing.

I know people who never make use of headings and the like to this day. Bold, italics, underline etc. is all they use. Despite writing larger documents. Admittedly, it took me a while to figure out and appreciate all the advantages of actually marking up the document structure properly.

These days I rarely reach for LaTeX or LibreOffice to craft new stuff in my private life. Simple text files is usually it. RST and Markdown if it has to be more fancy.

Oh dear, I got plenty of spam – if not even worse – on one of my jabber IDs. One sender JID was on exploit.net or exploit.im or something like that (I already forgot).

Two mates and I went on a 25km hike yesterday to the Wasserberg (lit. Water Mountain) and Fuchseck (lit. Fox Corner) on the edge of the Swabian Alb. They arrived by train and of course it was delayed by half an hour, “due to limited availability of tracks”. That was a first one, I never heard that reason before. Another train had a breakdown in a train station and later my mates’ train had to be rebooted, too. That restart alone took 10 minutes. O_o Software problem, it can’t be helped.

It rained the whole day before, so a lot of foot paths had turned into small creeks. Also, the mud levels were much higher than usual. We also took one or the other shortcut which were even messier. And also reeaalllly steep (see 07 and 08). It didn’t help that my guiding abilities also sucked a bit and I took the wrong turn twice. Oh well, we just explored new paths I’ve never been on. That’s a win in my book. :-)

After a rest at the Wasserberghaus with a Spezi, we then decided to also visit the Fuchseck, since we’re just around the corner. It took a bit longer that I remembered and after enyoing the view and eating homemade waffles with apple sauce, we then made our way home.

About 100 meters in front of the train station it began to rain. The thunderstorm caught up on us. We just made it in time, a couple of minutes later, the train was supposed to show up. I quickly walked home and was a bit soaked when I unlocked the front door.

It was great fun, it was a nice stroll for me, my mates were absolutely exhausted. Well, I admit, my feet hurt, too. :-)

Here’s a nice view on the Three Emperor-Mountains in the distance. From left to right: Hohenstaufen, Rechberg and Stuifen, the left one is my backyard mountain:

In-reply-to » QOTD: How large is your shell history? No history, 500 lines, 10'000, 100'000, something else?

@movq@www.uninformativ.de wc -l .zsh_history gives me 7100. That’s surprisingly a bit more than I thought. I used to regularly clear new stuff by hand and keep important commands to about twenty-something. I don’t recall the numbers anymore.
