(#lnzctjq) @lyse@lyse.isobeef.org They are optional dependencies and listed as such:

$ pacman -Qi pinentry
Name            : pinentry
Version         : 1.3.1-5
Description     : Collection of simple PIN or passphrase entry dialogs which
                  utilize the Assuan protocol
Optional Deps   : gcr: GNOME backend [installed]ā€Ø                      gtk3: GTK backend [installed]ā€Ø                      qt5-x11extras: Qt5 backend [installed]ā€Ø                      kwayland5: Qt5 backend
                  kguiaddons: Qt6 backend
                  kwindowsystem: Qt6 backend

And itā€™s probably a good thing that theyā€™re optional. I wouldnā€™t want to have all that installed all the time.

We finally got a caliper donated for this yearā€™s scout flea market. We didnā€™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. Itā€™s a wee bit banged up (probably happened during transport) and didnā€™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 didnā€™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. Itā€™s awesome, works absolutely perfectly and doesnā€™t smell the slightest bit. I reckon, this caliper box is plenty good enough for occasional use at our scout material store.

I was drafting support for showing ā€œapplication iconsā€ 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 donā€™t set an icon? And lots of other window managers donā€™t show these icons, either? Openbox, pekwm, Xfce, fvwm, no icons.

Looks like macOS doesnā€™t show them, either?!

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

(#euobsca) @lyse@lyse.isobeef.org @kat@yarn.girlonthemoon.xyz I spent so much time in the past figuring out if something is a dict or a list in YAML, for example.

What are the types in this example?

items:
- part_no:   A4786
  descrip:   Water Bucket (Filled)
  price:     1.47
  quantity:  4
- part_no:   E1628
  descrip:   High Heeled "Ruby" Slippers
  size:      8
  price:     133.7
  quantity:  1

items is a dict containing ā€¦ a list of two other dicts? Right?

It is quite hard for me to grasp the structure of YAML docs. šŸ˜¢

The big advantage of YAML (and JSON and TOML) is that itā€™s much easier to write code for those formats, than it is with XML. json.loads() and youā€™re done.

Only figured this out yesterday:

pinentry, which is used to safely enter a password on Linux, has several frontends. Thereā€™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 donā€™t configure it? Whatā€™s the default?

Turns out, pinentry is a shellscript wrapper and itā€™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 ā€¦

ā€¦ 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 ā€¦

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 itā€™s of this useless kind. Never thought that they ever actually will improve their Atom feeds. Thank you, much appreciated!

(#ijm24eq) @kat@yarn.girlonthemoon.xyz I have absolutely no idea, but I wouldnā€™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 ā€œfreezesā€ 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
ā†“
|......|.....|........|......|..
   ā†‘                      ā†‘
   Cut point      Cut point

Resulting video:

   ....|.....|........|....
   ā†‘ā†‘ā†‘ā†‘
   This is where it freezes

Could be complete bullshit, though. Wouldnā€™t be the first time that Iā€™m wrong. :-)

Iā€™m just curious, what exact command line do you use to cut the video?

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 ā€œmouse wheel clickā€ is:

(I think ā€œWayland compositorā€ 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. (Iā€™m not sure if thatā€™s possible, nor if people would want that.)

Xfce does one thing very right: It stores its settings in plain-text XML files. This allows me to easily read, track, and maybe even distribute these settings to other machines.

(Unlike GNOMEā€™s dconf, which uses some binary file format. Fun fact: The older and now deprecated gconf also used XML files.)

(#23mu5la) I think I understand now. Americans do not go camping, we do recreational activities. I donā€™t think campers are a thing here, but RVs (Recreational Vehicles) are. Thatā€™s why it would never cross my mind to get anything with fabric, that folds. No mate, we get a house on wheels, with a million miles engine. šŸ¤£

Other than that, it looks nice!
