It happened.

“Can you help me debug this program? I vibe coded it and I have no idea what’s going on. I had no choice – learning this new language and frameworks would have taken ages, and I have severe time constraints.”

Did I say “no”? Of course not, I’m a “nice guy”. So I’m at fault as well, because I endorsed this whole thing. The other guy is also guilty, because he didn’t communicate clearly to his boss what can be done and how much time it takes. And the boss and his bosses are guilty a lot, because they’re all pushing for “AI”.

The end result is garbage software.

This particular project is still relatively small, so it might be okay at the moment. But normalizing this will yield nothing but garbage. And actually, especially if this small project works out fine, this contributes to the shittiness because management will interpret this as “hey, AI works”, so they will keep asking for it in future projects.

How utterly frustrating. This is not what I want to do every day from now on.

I used to be able to sell my music anywhere in the world - and I have managed to send CDs to quite remote places, or kingdoms with nefarious regimes… but now, well, there is one country where I can not ship cassettes or CDs to: the USA 🇺🇸.

It’s not like I’m expecting any loss: I rarely sell music, and when I do it is rarely to the states (I don’t know why, I think my stuff ought to be way more popular! 😁). But still, it is disheartening to see there is now an effective wall, a country where I won’t be able to (directly) reach. Congratulations to everyone involved.

[PS: if you’re puzzled about what is this all about - a number of European countries, including Portugal, won’t be shipping stuff to the US due to legal uncertainty regarding Trump’s tariffs.]

After around 3 years, I managed to make my “smallest recognizable canine”, even smaller. So here’s the all new, smallest recognizable canine 2.0:

@lyse@lyse.isobeef.org Oh, huh, maybe it was just my GNOME 2 themes back then that didn’t show the icon. 🤔

I like the looks of your window manager. That’s using Wayland, right?

Oh, no. It’s still X11. All my recent Wayland comments resulted from me trying to switch, but I think it’s still too early. Being unable to use QEMU (because it can’t capture the mouse pointer) is a pretty big blocker for me. This is completely broken, it just happens to be unnoticeable with modern guest OSes, so it’s probably not a priority for devs.

(Not to mention that I would have to fork and substantially extend dwl in order to “replicate” my X11 WM. And then, after having done that, I’d have to follow upstream Wayland development, for which I don’t have the resources. Things would need to slow down before I can do that.)

all that wasted space of the windows not making use of the full screen!!!1

Heh. I’ve been using tiling WMs for ~15 years now, so it’s actually kind of refreshing to see something different for a change. 😅

Probably close to the older Windowses.

That particular theme is a ripoff of OS/2 Warp 3: https://movq.de/v/6c2a948882/s.png 😅

We ran some similar brownish color scheme (don’t recall its name) on Win95 or Win98

Oh god. Yeah, I wasn’t a fan of those, either. 🥴

@movq@www.uninformativ.de According to this screenshot, KDE still shows good old application icons: https://upload.wikimedia.org/wikipedia/commons/9/94/KDE_Plasma_5.21_Breeze_Twilight_screenshot.png

And GNOME used to have them, too: https://upload.wikimedia.org/wikipedia/commons/9/9f/Gnome-2-22_%284%29.png

I like the looks of your window manager. That’s using Wayland, right? The only thing on this screenshot to critique is all that wasted space of the windows not making use of the full screen!!!1 At least the file browser. 8-)

This drives me nuts when my workmates share their screens. I really don’t get it how people can work like that. You can’t even read the whole line in the IDE or log viewer with all the expanded side bars. And then there’s 200 pixels on the left and another 300 pixels on the right where the desktop wallpaper shows. Gnaa! There’s the other extreme end when somebody shares their ultra wide screen and I just have a “regularish” 16:10 monitor and don’t see shit, because it’s resized way too tiny to fit my width. Good times. :-D

Sorry for going off on a tangent here. :-) Back to your WM: It has the right mix of being subtle and still similar to motif. Probably close to the older Windowses. My memory doesn’t serve me well, but I think they actually got it fairly good in my opinion. Your purple active window title looks killer. It just fits so well. This brown one (https://www.uninformativ.de/blog/postings/2025-07-22/0/leafpads.png) gives me also classic vibes. Awww. We ran some similar brownish color scheme (don’t recall its name) on Win95 or Win98 for some time on the family computer. I remember other people visting us not liking these colors. :-D

@lyse@lyse.isobeef.org True, at least old versions of KDE had icons:

https://movq.de/v/0e4af6fea1/s.png

GNOME, on the other hand, didn’t, at least to my old screenshots from 2007:

https://www.uninformativ.de/desktop/2007%2D05%2D25%2D%2Dgnome2%2Dlaptop.png

I switched to Linux in 2007 and no window manager I used since then had icons, apparently. Crazy. An icon-less existence for 18 years. (But yeah, everything is keyboard-driven here as well and there are no buttons here, either.)

Anyway, my draft is making progress:

https://movq.de/v/5b7767f245/s.png

I do like this look. 😊

@movq@www.uninformativ.de I haven’t used KDE or GNOME for ages, but I’m sure KDE at least used to show application icons in the title bars. They proabably still do. But then, one could argue that KDE is mimicking Windows. I never thought like that, I always found KDE way superior, because I was able to configure it like a madman.

In i3, I don’t have any application icons. I remember missing them at the beginning. But I don’t even have the classical minimize, maximize and close buttons in the title bar either. Just the title. Being mostly keyboard driven and a tiling window manager, these buttons are not super useful, anyway.

I was drafting support for showing “application icons” in my window manager, i.e. the Firefox icon in the titlebar:

https://movq.de/v/0034cc1384/s.png

Then I realized: Wait a minute, lots of applications don’t set an icon? And lots of other window managers don’t show these icons, either? Openbox, pekwm, Xfce, fvwm, no icons.

Looks like macOS doesn’t show them, either?!

Has this grown out of fashion? Is this purely a Windows / OS/2 thing?

Since Wayland compositors handle input devices on a lower level than X11 window managers, every compositor has to figure out on their own what a “mouse wheel click” is:

• https://github.com/labwc/labwc/issues/1068
  
• https://github.com/labwc/labwc/pull/2933
  

(I think “Wayland compositor” is a misnomer. They are full-blown display servers that also do compositing, plus Wayland window management, plus X11 window management.)

One can only hope that all this eventually gets moved into the wlroots library. (I’m not sure if that’s possible, nor if people would want that.)

We covered quite some ground in the two and a half hours today. The weather was nice, mostly cloudy and just 23°C. That’s also why we decided to take a longer tour. We saw four deer in the wild, three of which I managed to just ban on film, quality could be better, though. My camera produced a hell lot of defocused photos this time. Not sure what’s going on with the autofocus. https://lyse.isobeef.org/waldspaziergang-2025-07-10/

@prologic@twtxt.net Yeah, this really could use a proper definition or a “manifest”. 😅 Many of these ideas are not very wide spread. And I haven’t come across similar projects in all these years.

Let’s take the farbfeld image format as an example again. I think this captures the “spirit” quite well, because this isn’t even about code.

This is the entire farbfeld spec:

farbfeld is a lossless image format which is easy to parse, pipe and compress. It has the following format:

╔════════╤═════════════════════════════════════════════════════════╗
║ Bytes  │ Description                                             ║
╠════════╪═════════════════════════════════════════════════════════╣
║ 8      │ "farbfeld" magic value                                  ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (width)                      ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4      │ 32-Bit BE unsigned integer (height)                     ║
╟────────┼─────────────────────────────────────────────────────────╢
║ [2222] │ 4x16-Bit BE unsigned integers [RGBA] / pixel, row-major ║
╚════════╧═════════════════════════════════════════════════════════╝

The RGB-data should be sRGB for best interoperability and not alpha-premultiplied.

(Now, I don’t know if your screen reader can work with this. Let me know if it doesn’t.)

I think these are some of the properties worth mentioning:

• The spec is extremely short. You can read this in under a minute and fully understand it. That alone is gold.
  
• There are no “knobs”: It’s just a single version, it’s not like there’s also an 8-bit color depth version and one for 16-bit and one for extra large images and one that supports layers and so on. This makes it much easier to implement a fully compliant program.
  
• Despite being so simple, it’s useful. I’ve used it in various programs, like my window manager, my status bars, some toy programs like “tuxeyes” (an Xeyes variant), or Advent of Code.
  
• The format does not include compression because it doesn’t need to. Just use something like bzip2 to get file sizes similar to PNG.
  
• It doesn’t cover every use case under the sun, but it does cover the most important ones (imho). They have discussed using something other than RGBA and decided it’s not worth the trouble.
  
• They refrained from adding extra baggage like metadata. It would have needlessly complicated things.

I didn’t manage to leave the house yesterday. But when I went into the woods this evening, activity first was 10% of what it had been the day before yesterday. By the end it got a lot busier, about 50% of last time I reckon. Around 500 fireflies I’d imagine. I might have been faster than the days before. When I left the forest, I was right in the fog, that was cool.

Shortly after, I saw another lightshow. Right behind the Wasserberghaus somewhere on the Swabian Alp there was very crazy heat lightning every 5-10 seconds. That looked absolutely amazing. :-)

“A coalition of determined open-source software (OSS) advocates and a handful of technology experts working in the European Commission set out in 2004 to end Microsoft’s monopoly. They almost succeeded. This article reveals how they managed to change the EU’s software policies, made Microsoft lobbyists work overtime - and in the end, and despite their best efforts, could not withstand the power of proprietary companies’ lobbying campaigns.

Drawing on the Multiple Streams Framework, the article explains the European Commission’s decision to promote OSS and open standards in 2004, and its puzzling decision to reverse course just a few years later, in 2010, despite its unchanged rhetoric about the benefits of openness. The analysis reveals three key factors that drove the changes in the EU’s policies.

In 2004, OSS advocates managed to frame the EU’s dependency on proprietary software as a problem – and the promotion of OSS and open standards as the solution.

In 2010, #Microsoft and other proprietary companies used their existing connections in Brussels to sow doubt about the maturity and cost of #OSS among #EU policymakers.”

Buying a TV these days, means trying to avoid endless enshitification:
-Spyware and adware
-Shitty AI upscaling/ frame interpolation
-HW that breaks after 2 - 3 years
-One off OS, dead on arrival
-Android OS, that starts lagging after the third update
-8 buttons worth of ads, on your remote

You probably have to make some kind of a compromise. I thought that was buying from some other brand like Hyundai, but that one also felt into some of those categories and just broke, after less than 3 years of use. At this point I’ll probably go back to LG and hope their HW is still reliable and the rest manageable… It has AI bullshit and knowing LG, probably some spyware you have to try your best to get rid of, can buy a remote with “only” 2 ads on it, some web-based OS shared between all their TVs, that usually gets 4 - 5 years worth of updates and works decently enough afterwards.

At this point, I’ll probably settle for anything that doesn’t literally fall apart, not even 3 years in, like the Hyundai did.

[$] Improving FUSE writeback performance
In a combined filesystem and memory-management session at
the 2025 Linux Storage, Filesystem, Memory

@@twtxt.net The fact that it has an SDK and process management is quite amazing g! 🤯

I visited a good mate after a day in the office and went for a stroll in the evening. It still was really hot, phew, about 24°C. Must have been the aftermath of the fire in the morning! For sure! The firealarm went off during a meeting and we all had to leave the building. Anyway, I only managed to take one lizard photo, all the other ones we came across immediately vanished in the brush or cracks in the vineyard walls. The kestrels were way more cooperative:

@bender@twtxt.net Well… I don’t believe it’s possible to prevent or avoid all system accidents. However, managing system safety and putting in control structures goes a long way 👌

@kat@yarn.girlonthemoon.xyz At the core, you need an ngircd.conf like this:

[Global]

    Ports = 6667

    AdminInfo1 = Well, me.
    AdminInfo2 = Over here!
    AdminEMail = forget.it@example.invalid

[Options]
    Ident = no
    PAM = no

[SSL]
    CertFile = /etc/ssl/acme/your.irc.server.com.fullchain.pem
    KeyFile = /etc/ssl/acme/private/your.irc.server.com.key
    DHFile = /etc/ngircd/dhparam.pem
    Ports = 6669

Start it and then you can connect on port 6667. (The SSL cert/key must be managed by an external tool, probably something like certbot or acme-client.)

[$] The problem of unnecessary readahead
The final session in the memory-management track of the 2025 Linux Storage,
Filesystem, Memory-Management, and BPF Summit was a brief, last-minute
addition run by Kalesh Singh. The kernel’s readahead mechanism is
generally good for performance; it ensures that data is present by the time
an application gets around to asking for it. Sometimes, though, readahead
can go a little too far. ⌘ Read more

Adding tracepoints to some kernel subsystems has been controversial—or

that may be changing. At the 2025 Linux Storage, Filesystem, Memory

whether the ABI concerns are outweighed by the utility of tracepoints for … ⌘ Read more

Even though I really do like the shell, I always use Dolphin to mount my digicam SD card and copy the photos onto my computer. I finally added a context menu item in Dolphin to create a forest stroll directory with the current date in order to save some typing:

Image

The following goes in ~/.local/share/kservices5/ServiceMenus/galmkdir.desktop:

[Desktop Entry]
Type=Service
X-KDE-ServiceTypes=KonqPopupMenu/Plugin,inode/directory
Actions=Waldspaziergang;

[Desktop Action Waldspaziergang]
Name=Heutigen Waldspaziergang anlegen…
Icon=folder-green
Exec=~/src/gelbariab/galmkdir "%f"

In order to update the KDE desktop cache and make this action menu item available in Dolphin, I ran:

kbuildsycoca5

The referenced galmkdir script looks like that:

#!/bin/sh
set -e

current_dir="$1"
if [ -z "$current_dir" ]; then
    echo "Usage: $0 DIRECTORY" >&2
    exit 1
fi

dir="$(kdialog \
    --geometry 350x50 \
    --title "Heutigen Waldspaziergang anlegen" \
    --inputbox "Neues Verzeichnis in „$current_dir“ anlegen:" \
    "waldspaziergang-$(date +%Y-%m-%d)")"
mkdir "$current_dir/$dir"
dolphin "$current_dir/$dir"

This solution is far from perfect, though. Ideally, I’d love to have it in the “Create New” menu instead of the “Actions” menu. But that doesn’t really work. I cannot define a default directory name, not to mention even a dynamic one with the current date. (I would have to update the .desktop file every day or so.) I also failed to create an empty directory. I somehow managed to create a directory with some other templates in it for some reason I do not really understand.

Let’s see how that works out in the next days. If I like it, I might define a few more default directory names.

my main itch with the DMs extensions is that these messages are intended to be private, not public information. That’s why other extensions make sense, but DMs are another kind of feature.
TwiXter, Mastodon, FB and some other services usually hide the DMs in another section, so they are not mixed with the public timeline.

I find the DM topic interesting, I even made an indie experiment for a centralized messaging system here https://github.com/eapl-gemugami/owl.
Although, as I’ve said a few times here, I’m not particularly interested in supporting it on microblogging, as I don’t use it that much. In the rare case I’ve used them, I don’t have to manage public and private keys, and finally none of my acquaintances use encrypted email.
Nothing personal against anyone, and although I like to debate and even fight, it’s not the case here. This proposal is the only one allowing DMs on twtxt, and if the community wants it, I’ll support it, with my personal input, of course.

A good approach I could find with a good compromise between compatibility with current clients and keeping these messages private is ‘hiding’ the DMs in comments. For example:
# 2025-04-13T11:02:12+02:00 !<dm-echo https://dm-echo.andros.dev/twtxt.txt> U2FsdGVkX1+QmwBNmk9Yu9jvazVRFPS2TGJRGle/BDDzFult6zCtxNhJrV0g+sx0EIKbjL2a9QpCT5C0Z2qWvw==

[$] Automatic tuning for weighted interleaving
It is common, on NUMA systems, to try to allocate all memory on the local
node, since it will be the fastest. That is not the only possible policy,
though; another is weighted interleaving,

the bandwidth utilization on each. Configuring such policies can be

[$] In search of a stable BPF verifier
BPF is, famously, not part of the kernel’s promises of user-space stability. New
