Russian Spam and Profanities Are Now Plaguing the Arch Linux AUR
The Arch Linux User Repository “AUR” is facing another issue just days after more than 1,500 packages were found carrying malware. According to Phoronix, over 70 AUR packages have reportedly been modified to insert Russian spam and profane messages into users’ shell configuration files. From the report: Nicolas Boichat with his AI/LLM detection bot … ⌘ Read more

Every now and then, I think that I have carefully proof-read my message enough times and hit the “Add message” button in tt. But then, in the message tree, I spot another missed typo. My process is then to go to my twtxt.txt and fix it by hand. However, I still have to clean up tt’s cache. This is rather tidious:

1. Recall the sqlitebrowser ~/.local/share/twtxt/tt2.sqlite from my shell history.
   
2. Switch to the “Browse data” tab.
   
3. Go to the messages table and wait a second or two until it’s loaded.
   
4. Sort by the created_at column twice, so that I get descending order.
   
5. Select the first message, which is typically the one in question.
   
6. Find the “Remove currently selected row” button in the tool bar.
   
7. Commit the changes.
   
8. Close sqlitebrowser.
   

So, I finally implemented the removal of messages from the cache in tt. I can now hit d and confirm the removal. Bam! Should have done that ages ago!

Next up is the search, I think.

I went to check on the fireflies this season. But I didn’t see any. Instead lots of moths. At first, I thought it might have been still too light, but it was already dark enough for me to miss and destroy a snail shell. Bummer. Maybe it was too wet tonight. Although, it’s probably just another or two weeks until my glowing friends will finally show up.

In the beginning, I passed two beautiful deer on the edge of the forest. They were just ten meters away, but didn’t run off, really cool. :-) I kept on walking. Before I eventually left the woodland, a frog or toad crossed my path. It was very dark by then, though, so all I could see was a black blob.

Back in town, the street lamps on the first third were all turned off for some reason. I was already glad that I will reach home without getting blinded this time, but unfortunately, the other lamps were all operational.

@movq@www.uninformativ.de Ah, I see. Oh, so not even make, just a shell script. :-)

@lyse@lyse.isobeef.org Ah, I almost thought so (that you wrote it by hand), but then I looked at the source code and saw the TOC and I was like: “Naah, probably not. I would be way too lazy to do that manually.” 😅 And indeed … ha.

Oh god, yeah, that’s a lot of <span>. 🤔 Can’t really avoid that, I guess, especially if you want to do syntax highlighting of code blocks.

You wrote your own site generator, didn’t you?

In parts. I write everything in Markdown (it’s online, even: https://movq.de/blog/postings/2026-05-29/0/POSTING-en.md), plus a few Vim shortcuts (to generate thumbnails, for example), and then python-markdown renders it: https://pypi.org/project/Markdown/ This process is wrapped in a shell script, like “re-render every page if the .md file is newer than the .html file” and that’s mostly it. And the Atom feed generator is completely custom. 🤔

Okay, I had heard of “River” before but I was not aware of this:

https://codeberg.org/river/river

River defers all window management policy to a separate window manager implementing the river-window-management-v1 protocol. This includes window position/size, pointer/keyboard bindings, focus management, window decorations, desktop shell graphics, and more.

This sounds promising and it follows the old X11 model. River does all the nasty Wayland work and I can make just the WM? 🤔🤯

I’ve got a prototype of my hardcopy simulator going. I’m typing on the keyboard and the “display” goes to the printer:

https://movq.de/v/235c1eabac/MVI_8810.MOV.mp4

The biiiiiiiiiig problem is that the print head and plastic cover make it impossible to see what’s currently being printed, because this is not a typewriter. This means: In order to see what I just entered, I have to feed the paper back and forth and back and forth … it’s not ideal.

I got that idea of moving back/forth from Drew DeVault, who – as it turned out – did something similar a few years back. (I tried hard to read as little as possible of his blog post, because figuring things out myself is more fun. But that could mean I missed a great idea here or there.)

But hey, at least this is running on my Pentium 133 on SuSE Linux 6.4, printer connected with a parallel cable. 😍

(Also, yes, you can see the printouts of earlier tests and, yes, I used ed(1) wrong at one point. 🤪 And ls insisted on using colors …)

Something happened with the frame rate of terminal emulators lately. It looks like there’s a trend to run at a high framerate now? I’m not sure exactly. This can be seen in VTE-based terminals like my xiate or XTerm on Wayland. foot and st, on the other hand, are fine.

My shell prompt and cursor look like this:

$ █

When I keep Enter pressed, I expect to see several lines like so:

$
$
$
$
$
$
$ █

With the affected terminal emulators, the lines actually show up in the following sequence. First, we have the original line:

$ █

Pressing Enter yields this as the next frame:

$
█

And then eventually this:

$
$ █

In other words, you can see the cursor jumping around very quickly, all the time.

Another example: Vim actually shows which key you just pressed in the bottom right corner. Keeping j pressed to scroll through a file means I get to see a j flashing rapidly now.

(I have no idea yet, why exactly XTerm in X11 is fine but flickering in Wayland.)

The WM_CLASS Property is used on X11 to assign rules to certain windows, e.g. “this is a GIMP window, it should appear on workspace number 16.” It consists of two fields, name and class.

Wayland (or rather, the XDG shell protocol – core Wayland knows nothing about this) only has a single field called app_id.

When you run X11 programs under Wayland, you use XWayland, which is baked into most compositors. Then you have to deal with all three fields.

Some compositors map name to app_id, others map class to app_id, and even others directly expose the original name and class.

Apparently, there is no consensus.

Just discovered how easy it is to recall my last arg in shell and my brain went 🤯 How come I’ve never learned about this before!? I wonder how many other QOL shortcuts I’m missing on 🥲
