I’m supporting incremental SQLite schema changes to just upgrade from an older database version to whatever the current software version supports. In the past, I already noticed that this is quite expensive in unit tests when each test case runs through the entire schema patches and applies them one by one.

To speed up test execution I now decided that I finally go through the troubles of maintaining both a set of incremental patches and a full schema setup in one go. A unit test verifies that both ways end up with the same structure. This gives me a set of SQLs to check the structures:

SELECT type, name, tbl_name, sql
FROM sqlite_schema
ORDER BY type, name, tbl_name

Unfortunately, the resulting CREATE TABLE SQL queries are formatted differently, depending on whether the full schema was set up in one big step or the structure had been modified with ALTER TABLE. Mainly, added columns are not on their own lines but appended in one physical line. That’s why I wanted an SQL formatting tool. Since I didn’t find one that works decently, I’m now doing some simple string manipulation. Joining consecutive whitespace into a single space character, removing spaces before commas and closing parentheses and spaces after opening parentheses. This works surpringly good enough. Of course, if it fails, the “diff” is absolutely horrendous.

Now for the cool part, my test execution dropped from around 5:05 minutes to just 1:32 minutes! I call that a win.

I just stumbled across PRAGMA table_info('tablename') https://sqlite.org/pragma.html#pragma_table_info, PRAGMA foreign_key_list('tablename') and friends. I guess, I have to play with that, now. It’s probably much better to use than the SQL text approach.

@lyse@lyse.isobeef.org 😂 Pretty cool remix(?)!

@rdlmda@rdlmda.me it is called, in Spanish, “the mother”. It is created through a bit (not by much) effort, and kept as a starting point. Just like Asian cuisine has dishes that never cool, always cooking leaving always a base on it.

@movq@www.uninformativ.de oh yeah, we have heard plenty. The re-entry boom of the shuttles (when they were in service) and, more recently, of the SpaceX rockets boosters. Depending on weather conditions we might hear a lot, or nothing at all.

I will try capturing a “regular” launch as I see it from home one of these days. It is a curved white, blueish line in the sky, with a big, incandescent tip (the actual rocket burners, and boosters). Pretty cool sight.

ARCTIC Cooling Publishes ARCTIC Fan Controller Driver For Linux
A Linux driver has been published for the ARCTIC Fan Controller to be able to read fan speeds under Linux as well as setting the PWM fan speed for each of the ten fans supported by this controller. Making this driver all the more exciting is that ARCTIC Cooling is directly working on this driver rather than just being a community/third-party creation.

It’s raining and raining and raining and raining. I had hoped my mate canceled the hike today. But he didn’t. He showed up. So, off we went to the Staufeneck Castle Ruin after having a lunch first. The rain drizzling on the umbrella was very nice and I was very glad that he dragged me outside.

It was super wet, though. Entire creeks were coming down on some path sections. A slippery, muddy mess on others. Our boots were already soaked a few kilometers in the trip. The important part was that the feet were warm, though, despite being wet. We barely met anybody in this lousy weather. So we had basically everything for us alone. That’s always great.

Visibility was poor the higher we got. At 13 a low hanging cloud was moving in, 14 is the result just three minutes later. We couldn’t see the castle 300 meters away anymore. No chance. It was really funny, because the houses in town at two kilometers distance were still visible. Poorly, but you could clearly make out the town. Not the castle, there was just a white wall of cloud :-)

On the way back, we warmed up with tea I brought along. After I dropped off my mate at the train station, I bumped into a fellow scout, so my wet feet cooled off completely in these 15 minutes we talked. The rainjacket mostly held up with the protection of the umbrella, just the sleeves were down. My rain trousers, on the other hand, leaked a little bit a the lower ends. I was glad when I could strip all the wet stuff. I would do it again, though. :-) Now, I’m swapping the newspaper in my boots every half an hour to absorb all the moisture.

@movq@www.uninformativ.de I’ve got the same problem that you had the other day: finding past temperature data. But yeah, it looked much warmer than it actually was. Maybe 5°C? Possibly less when I found myself in the snow- and rainstorm in the end.

With the wind, my fingers were frozen. I should have worn gloves. Without them, I could only put my hands in the pockets of my jacket. That didn’t help much, though, because I frequently stopped to take yet another photo, so they cooled off again right away. :-D

Balancing the big/long, closed umbrella under my arm while I had my hands burried was also a little tricky.

First world problems. :-)

@abucci@anthony.buc.ci coined the term “failscene”:

https://buc.ci/abucci/p/1771250567.039684

I wonder about using “failscene” to describe the current slate of AI tools and demos. In contrast with the demoscene, which is about getting very low powered computers to do cool things you wouldn’t expect them to be able to do, the failscene is about getting very high powered computers to fail at doing boring things we already know how to do without them. Plus you can stylize it fAIlscene if you’re inclined to.

I love it.

There was an endless coming and going of sun, clouds and rain. Not to forget about the wind. I called it quits a bit earlier and went into the woods.

Towards the end I was completeley surrounded by rain curtains in all directions. This looked super cool. I thought I might make it home just in time without having to use my umbrella, but the rain clouds were way quicker than I anticipated. Just after the rain hit me, I met an acquaintance who just started his walk. The wind picked up hard and rain hammered down, mixed with snow. Holding the umbrella was a workout. Shortly after I returned, the rain stopped again.

I didn’t notice the kestrel sitting on the tree when I took the last photo. That was a nice surprise when I sorted through the nearly 300 pics.

@movq@www.uninformativ.de I see. Yeah, if you gotta have to tediously plow through, it feels deeper. And sometimes it actually is.

We had super thick fog this morning. It rolled in extremely quickly, maybe 15 minutes at most. Visibility was below 50 meters. Looked cool from inside.

What a beautiful, beautiful 0°C Sunday arvo and evening! The weather forecast delayed the snow by the minute. An hour or so after it finally started very, very lightly, I headed off for the woods to check out the lake again. Unfortunately, with the fresh snow layer, the crazy wild surface texture of the ice sheet wasn’t visible anymore. But it brought some other nice views and photo opportunities.

I initially thought that I just go for a quick turn. However, with the snowfall a wee bit increasing I was hooked and kept going. Visibility was poor, but the snow blankets just looked too stunning. The road surfaces were quite slippery, so I often just walked alongside the pathways. On downhill slopes I had some good fun sliding down the road on my feet. With varying success. Luckily, I managed not to fall.

On the summit of the mountain the twigs had those absolutely magnificently looking windblown crystal coverings. Awwwwwww! They never get old. It was already getting dark, so the camera was tired and wanted to sleep. The snow program then made use of the flash and I’m quite pleased with how these shots turned out.

Two deer crossed the road in front of me and ran into the woods, that was sight for sore eyes. Although I felt bad that they had to flee from me in this white terrain. By the time I got home, the snow had accumulated around eight centimeters in height, even in town down in the valley. Walking on this fresh snow is just amazing. And I love the sound it makes. Today, the snow consistency must have been just right, because the crushing sound was really loud.

I cannot recall that I had frozen hair and beard before, but today, there was a thick ice buildup. In case I had, it was definitely never this much. Felt really cool.

Enough of this preliminary skirmishing, there ya go: https://lyse.isobeef.org/waldspaziergang-2026-01-25/

@movq@www.uninformativ.de Cool, cool, cool! Happy hacking. :-)

Another project where I’m going to use my terminal widget toolkit is a hex editor. This is still very young, obviously, and there’s a lot of work to do (both in the toolkit and this particular application), but I’m making some progress:

https://movq.de/v/2bae14ed16/vid-1769283187.mp4

Since this program is UTF-8 clean (I hope), you can do things like enter multi-byte UTF-8 sequences or paste them from the system clipboard (another hex editor I just tried failed to do this correctly):

https://movq.de/v/e9241034c1/vid-1769283755.mp4

Under the hood, I’m using mmap() with MAP_PRIVATE, which is really cool: I get the entire file as a byte array, no matter how large it is, no need to actually read it upfront; and MAP_PRIVATE means that I can write to this area however I like without changing the underlying file. The kernel does copy-on-write for me. Only when you hit Save, it will write to the filesystem. And it’s just a couple lines of code. The kernel does all the magic. 🥳

Scrolling widgets appears to work now. This is (mostly) Unicode-aware: Note how emojis like “😅” are double-width “characters” and the widget system knows this. It doesn’t try to place a “😅” in a location where there’s only one cell available.

Same goes for that weird “ä” thingie, which is actually “a” followed by U+0308 (a combining diacritic). Python itself thinks of this as two “characters”, but they only occupy one cell on the screen. (Assuming your terminal supports this …)

This library does the heavy Unicode lifting: https://github.com/jquast/wcwidth (Take a look at its implementation to learn how horrible Unicode and human languages are.)

The program itself looks like this, it’s a proper widget hierarchy:

(There is no input handling yet, hence some things are hardwired for the moment.)
