In-reply-to » You can explicitly use colors in manpages. I saw this in the apt manpage of Ubuntu recently, which, for some reason, uses blue text in one place:

Ah, so apparently they don’t like writing manpages anymore and instead use XML:

https://salsa.debian.org/apt-team/apt/-/blob/main/doc/apt.8.xml

And then they use XSLT on top and what not:

https://salsa.debian.org/apt-team/apt/-/blob/main/doc/manpage-style.xsl.cmake.in

It’s not even explicitly blue:

Makes little sense to me. I’m glad that most manpages don’t do this. I wouldn’t want unicorn vomit all over the place.

Using colors can be done using the low level commands \m and \M:

.TH foo_program 3
\m[blue]I'm blue\m[], da ba dee.
\m[red]\M[yellow]I'm red on yellow.\m[]\M[]
This is quite horrible.

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.

@kat@yarn.girlonthemoon.xyz On the one hand, all these programs have a very long history and the technology behind manpages is actually very powerful – you can use it to write books:

https://www.troff.org/pubs.html

I have two books from that list, for example “The UNIX programming environment”:

https://movq.de/v/c3dab75c97/upe.jpg

It’s a bit older, of course, but it looks and feels like a normal book, and it uses the same tech as manpages – which I think is really cool. 😎

It’s comparable to LaTeX (just harder/different to use) but much faster than LaTeX. You can also do stuff like render manpages as a PDF (man -Tpdf cp >cp.pdf) or as an HTML file (man -Thtml cp >cp.html). I think I once made slides for a talk this way.

On the other hand, traditional manpages (i.e., ones that are not written in mandoc) do not use semantic markup. They literally say, “this text is bold, that text over here is italics”, and so on.

So when you run man foo, it has no other choice but to show it in black, white, bold, underline – showing it in color would be wrong, because that’s not what the source code of that manpage says.

Colorizing them is a hack, to be honest. You’re not meant to do this. (The devs actually broke this by accident recently. They themselves aren’t really aware that people use colors.)

If mandoc and semantic markup was more commonly used, I think it would be easier to convince the devs to add proper customizable colors.

Since Fastly acquired and recently shut down glitch.com, some of my ancient webapps are no longer available, nor do I have any plans to make them available again - all had either zero, or very few monthly visits, used outdated libraries and would be a waste of money, to continue hosting and updating elsewhere.

All art archives remain unaffected and all projects shut down before 2025, were already permanently deleted, but if there’s someone out there, still relying on the recently discontinued projects, somehow - you can reach out and request their source code.

These requests will only be honoured, until the end of this year, when we plan to permanently delete, all of this data (both webapps and files only hosted on Amazons CDN).

Stuff that nobody needs:

systemctl uses ANSI escape codes to underline text (\e[4m) and then it also uses special escape codes – that Wikipedia classifies as “not in the standard”, but I haven’t looked it up – to change the color of the underline. That color change is barely noticeable in the first place.

Some terminals don’t support this and now my systemctl output is blinking because of that.

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

@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 😅

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.

@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.

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.

We finally got a caliper donated for this year’s scout flea market. We didn’t sell it, but kept it ourselves. It will come in very handy every now and then in our material store. For example, I missed having a caliper in the past when sorting our random assortment of screws or measuring the depth of a hole. It’s a wee bit banged up (probably happened during transport) and didn’t come with a box, but the latter is now solved.

The lid and bottom came from a wardrobe back panel I got from a mate, the sides were rocket sticks in their former lives. I found some scrap of felt in our material store and some hinges laying around in the drawers of my own workshop.

Unfortunately, the table saw teared up the plywood veneer fibres badly, even though I put tape around to prevent that. This is the first time it didn’t work. At. All. To cover that up, I painted the box with some decades old tinting paint (price tag says Deutsche Mark, not Euro!) from my paint cabinet. It’s awesome, works absolutely perfectly and doesn’t smell the slightest bit. I reckon, this caliper box is plenty good enough for occasional use at our scout material store.

Only figured this out yesterday:

pinentry, which is used to safely enter a password on Linux, has several frontends. There’s a GTK one, a Qt one, even an ncurses one, and so on.

GnuPG also uses pinentry. And you can configure your frontend of choice here in gpg-agent.conf.

But what happens when you don’t configure it? What’s the default?

Turns out, pinentry is a shellscript wrapper and it’s not even that long. Here it is in full:

#!/bin/bash

# Run user-defined and site-defined pre-exec hooks.
[[ -r "${XDG_CONFIG_HOME:-$HOME/.config}"/pinentry/preexec ]] && \
        . "${XDG_CONFIG_HOME:-$HOME/.config}"/pinentry/preexec
[[ -r /etc/pinentry/preexec ]] && . /etc/pinentry/preexec

# Guess preferred backend based on environment.
backends=(curses tty)
if [[ -n "$DISPLAY" || -n "$WAYLAND_DISPLAY" ]]; then
        case "$XDG_CURRENT_DESKTOP" in
        KDE|LXQT|LXQt)
                backends=(qt qt5 gnome3 gtk curses tty)
                ;;
        *)
                backends=(gnome3 gtk qt qt5 curses tty)
                ;;
        esac
fi

for backend in "${backends[@]}"
do
        lddout=$(ldd "/usr/bin/pinentry-$backend" 2>/dev/null) || continue
        [[ "$lddout" == *'not found'* ]] && continue
        exec "/usr/bin/pinentry-$backend" "$@"
done

exit 1

Preexec, okay, then some auto-detection to use a toolkit matching your desktop environment …

… and then it invokes ldd? To find out if all the required libraries are installed for the auto-detected frontend?

Oof. I was sitting here wondering why it would use pinentry-gtk on one machine and pinentry-gnome3 on another, when both machines had the exact same configs. Yeah, but different libraries were installed. One machine was missing gcr, which is needed for pinentry-gnome3, so that machine (and that one alone) spawned pinentry-gtk

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.

In-reply-to » @kat why does ffmpeg always freeze the video in the first five seconds after a cut lmfao

@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, it’s not a strong sandbox in jenny’s case, it could still read my SSH private key (in case of an exploit of some sort). But I still like it.

I think my main takeaway is this: Knowing that technologies like Landlock/pledge/unveil exist and knowing that they are very easy to use, will probably nudge me into writing software differently in the future.

jenny was never meant to be sandboxed, so it can’t make great use of it. Future software might be different.

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.

@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’ve been silently wondering all the time if this was possible, but never investigated: Keep doing X11 but use Wayland as a backend.

This uses XWayland’s “rootful” mode, which basically just gives you a normal Wayland window with all the X11 stuff happening inside of it:

https://www.phoronix.com/news/XWayland-Rootful-Useful

In other words, put such a window in fullscreen and you (more or less) have good old X11 running in a Wayland window.
