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.

@kat@yarn.girlonthemoon.xyz Uuhh, a rooftop concert! That sounds sick. I first learned about this in Electric Callboy’s tour report. They played the same location last year.

Heck yeah, you managed to be in the front rows. :-) I never heard about Rilo Kiley before, but the two songs I just listened to are good. Something to relax to.

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: 😅

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:

Image

And GNOME used to have them, too:

Image

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 (

Image

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

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

Image

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:

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:

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/

When the sun came out, colors were just beautiful:

@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. :-)
