I went on a short stroll in the woods and came across two great spotted woodpeckers. They were busy with their courtship display, I reckon, so it took them a while to notice me and escape into thicker parts out of sight. That was really awesome. There are a lot of apples and sloes now, looking really good. The cam issues still persist, though, I wish the photos were sharper. Also, I got the error that the function wheel was not adjusted correctly and alledgedly pointed between two options numerous times. And no, it was bang on a setting. https://lyse.isobeef.org/waldspaziergang-2025-10-07/

Hiring in high-growth firms: Exploring the timing of organizational changes
High-growth firms (HGFs) refer to businesses that achieve rapid growth in terms of employees or revenue. Based on the established definition, HGFs are businesses with at least 10 employees and annual growth rates of 20% or more, observed over a period of three years. This three-year span is considered the high-growth (HG) period of the company. Even though this growth is often short-lived and difficult to sustain, it plays … ⌘ Read more

Thank you, @alexonit@twtxt.alessandrocutolo.it! It’s not sealed at all. If you were pouring in a liquid, it would run out on all four corners. It’s just folded over and carefully hammered shut as best as possible. 03 is a bit blurred, but you can see the tab from the right (the short side) tucking in on the left (the long side). The hem on top clamps it in place fairly decently.

I decided against blind rivets, because they leave ugly looking and sharp backsides, which can also interfer with the contents of the box. However, they would be an easy solution to make the corners more rigid and prevent any movement from the short sides.

Unfortunately, I can’t weld or solder, so that’s not an option. It would be the by far best solution. I wanna learn it one day, though.

Yes, Ken is a really great dude. He’s the reason I gave this a shot in the first place. :-)

Here’s an example of X11/Xlib being old and archaic.

X11 knows the data type “cardinal”. For example, the window property _NET_WM_ICON (which holds image data for icons) is an array of “cardinal”. I am already not really familiar with that word and I’m assuming that it comes from mathematics:

https://en.wikipedia.org/wiki/Cardinal_number

(It could also be a bird, but probably not: https://en.wikipedia.org/wiki/Cardinalidae)

We would probably call this an “integer” today.

EWMH says that icons are arrays of cardinals and that they’re 32-bit numbers:

https://specifications.freedesktop.org/wm-spec/latest-single/#id-1.6.13

So it’s something like 0x11223344 with 0x11 being the alpha channel, 0x22 is red, and so on.

You would assume that, when you retrieve such an array from the X11 server, you’d get an array of uint32_t, right?

Nope.

Xlib is so old, they use char for 8-bit stuff, short int for 16-bit, and long int for 32-bit:

https://x.org/releases/current/doc/libX11/libX11/libX11.html#Obtaining_and_Changing_Window_Properties

That is congruent with the general C data types, so it does make sense:

https://en.wikipedia.org/wiki/C_data_types

Now the funny thing is, on modern x86_64, the type long int is actually 64 bits wide.

The result is that every pixel in a Pixmap, for example, is twice as large in memory as it would need to be. Just because Xlib uses long int, because uint32_t didn’t exist, yet.

And this is something that I wouldn’t know how to fix without breaking clients.

I have a Python script that transforms the original YouTube channel Atom feed into a more useful Atom feed by removing the spam description and replacing it with the video duration, filtering out videos by title, duration, etc. I just updated it to exclude the damn Shorts garbage more efficiently. Finally, YouTube updated their Atom feed generation, so that the video URL contains /short/ if it’s of this useless kind. Never thought that they ever actually will improve their Atom feeds. Thank you, much appreciated!

Morning, computer! Spending my days off trying to figure things out.
Some of them will occur in this post. I think best when I’m writing,
after all.

I’m back from a short vacation since a couple of weeks. I’m still
going to take a few days off every week for a while. I need the break.
It’s been way too many 12-16 hour workdays. I’m nominally working 80%
(~6 hour days), so I figure I’ve been working a lot for free.

Yeah, well, I like the TKey project to succeed. The ideas behind it

Open Sauce is nearly here!! ⌘ Read more

@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.

10 Iconic “Temporary” Structures That Still Stand Today
