Severe but funny burn-ins on my TFT again:

Now everything looks like it has that silly slogan as a background image:

Working on a project that does Augmented Reality and computer vision object detection and QR code and image recognition inside a Web application. Pretty neat what can be done today with a few thousand lines of JavaScript.

The image needs to be an absolute URL, and some tags are missing. Almost there!

@movq@www.uninformativ.de Interesting, yes. I didn’t know that.

No AI being used is really great. However, the same clips shown over and over again and some images being mirrored was quite annoying to me. Also, there were some quite terrible computer animations and sometimes the narration and picture didn’t match at all. Talking about the medieval period and then showing an image from the 18th hundred or so. What the heck?

These production issues made me sceptical pretty much early on. So I quickly crosschecked Wikipedia. But it seems spot on from what I’ve read. Very good. Also, the narrator’s voice was really nice to listen to.

Eels are fascinating creatures. :-)

@eric@itsericwoodward.com Hmm, the images are all 404ing. Also, I reckon that lots of code blocks are broken, too.

@movq@www.uninformativ.de Hahaha, great idea! :-D I never saw the Epson Image Scan logo before.

This is something that @kat@yarn.girlonthemoon.xyz might enjoy:

Recreating the “EPSON Image Scan!” logo with one of my Tux plushies. 😅

@prologic@twtxt.net It’s quite similar to how escape sequences work in a terminal. ASCII text is printed as ASCII text and then an escape sequence can make it bold or underline and so on. Other escape sequences allow you to say “the following $n bytes are part of a bitmap image”, and then this gets printed at whatever the current position is (somewhat similar to SIXEL in a terminal).

It’s just that the units are a bit weird, because this is all done in bloody inch. 😅

This is why I love tech from that era.

Write bytes to a parallel port and stuff happens. If it’s just ASCII bytes, then it will print ASCII text. Even the simplest programs can use a printer this way.

With a little bit of ESC/P, you can print images and other fancy stuff. That’s what I did this morning – never worked with ESC/P before, now I can print images. It’s not that hard.

Hayes-compatible modems are similar: Write some AT commands to the serial port and the modem does things. This isn’t even arcane knowledge, it’s explained in the printed manual.

Maybe I’m wearing rose-tinted glasses here, but I think with all this old stuff, you get useful results very quickly and the manuals are usually actually helpful. It’s so much easier to get started and to use this hardware to the full extent. Much less complexity than what we have today, not a ton of libraries and dependencies and SDKs and cloud services and what not.

@movq@www.uninformativ.de Thanks, glad you like it, but sadly I’m not sure, if there’s still a way, for this particular project, to continue.

Reducing 38 pixels (previous smallest) to 27, inside of a 7x7 square canvas, is a result I’m really happy with. Now it seems I can only shave off single pixels and get a lot worse looking results - to the point it doesn’t even look like my mascot, to me.

There doesn’t seem to be a hard cap for drawing tiny dogs. It’s possible to arrange 5 pixels, in a way someone recognizes them, as some kind of a dog. The record for cats, is currently a single orange pixel: https://youtu.be/gzeK8NKuzmg

The only way to beat that, is either a monitor, with just a single red diode lit, inside one of its pixels, or an image file that’s broken and empty, on purpose.

Distrobox is pretty handy and kind of amazed I haven’t played with it before now. I wanted to quickly try out Proton’s Authenticator they just released, but they only had binaries for Ubuntu and Fedora (naturally), but I’m on Void Linux on this laptop.

Installed the latest basic Fedora image with Distrobox, used dnf to install the downloaded rpm file within it, and presto, running the app within Void like I’d just downloaded it though the normal repos.

YAYYY TY @prologic@twtxt.net NOW I HAVE IMAGE & YOUTUBE EMBEDS ON MY YARN POD 🎉🎉🎉

There is a missing feature I’ve been intending to add to though, which is that any link that looks like a URL that might be an image, for example, ends with .png or .jpg or whatever, we should just render that as an image and not expect users to wrap it in Markdown image links ![](...)

@kat@yarn.girlonthemoon.xyz Ahh what do you mean by images don’t embed? They definitely should! By default however all domains are blocked, so you might want to either allow some domains or just put in a .* entry to allow all/any domsins. Screenshot attached

on my yarn pod nothing really embeds (not even images) so i’m looking at the embed rules part of the mod settings and i’m like… i don’t know how to do any of this 😭😭😭

@thecanine@twtxt.net image is so real lol literally me

@kat@yarn.girlonthemoon.xyz I BELIEVE IN U!!! Making it fun helps! Maybe like put images in the docs so it’s cuter to look at! I did that, but with physical journaling. Except instead of pics it was receipts & leaves & dried flowers lol

@lyse@lyse.isobeef.org To be fair, I did first notice this a while ago. But no monitor I ever had showed burn-ins like this (be it TFT or CRT), so I didn’t know that I should have sent it back. And then it got worse over time and now I see ghost images after 20-30 minutes. :(

wrote a script to make epic aesthetic half tone images and i was impressed with myself how fast i did it but to be fair i already had the commands noted down and i just had to script it lmfao

Do I buy a new monitor or do I live with the burn-ins all the time? It’s getting annoying. When I edit images in GIMP, I have to double check if something is a pixel or a burn-in.

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.

@kat@yarn.girlonthemoon.xyz I have absolutely no idea, but I wouldn’t be surprised if it uses the closest full image after your cut point and not the one before. Hence, the deltas between the two full images have nothing to really refer to. So, the video player just shows the first full image it finds and “freezes” the image until the video stream actually hits it.

Let me try to visualize it, | represent full images, . just subsequent deltas:

Original start of video
↓
|......|.....|........|......|..
   ↑                      ↑
   Cut point      Cut point

Resulting video:

   ....|.....|........|....
   ↑↑↑↑
   This is where it freezes         

Could be complete bullshit, though. Wouldn’t be the first time that I’m wrong. :-)

I’m just curious, what exact command line do you use to cut the video?

@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.
