↳ In-reply-to » @zvava @lyse I also think a location based reference might be better.

Here is just a small list of thingsā„¢ that Iā€™m aware will break, some quite badly, others in minor ways:

  1. Link rot & migrations: domain changes, path reshuffles, CDN/mirror use, or moving from txt ā†’ jsonfeed will orphan replies unless every reader implements perfect 301/410 history, which they wonā€™t.
  2. Duplication & forks: mirrors/relays produce multiple valid locations for the same post; readers see several ā€œparentsā€ and split the thread.
  3. Verification & spam-resistance: content addressing lets you dedupe and verify youā€™re pointing at exactly the post you meant (hash matches bytes). Location anchors can be replayed or spoofed more easily unless you add signing and canonicalization.
  4. Offline/cached reading: without the original URL being reachable, readers canā€™t resolve anchors; with hashes they can match against local caches/archives.
  5. Ecosystem churn: all existing clients, archives, and tools that assume content-derived IDs need migrations, mapping layers, and fallback logic. Expect long-lived threads to fracture across implementations.

ok so i have found a genuine twt hash collision. what do i do.

internally, bbycll relies on a post lookup table with post hashes as keys, this is really fast but i knew iā€™d inevitably run into this issue (just not so soon) so now i have to either:
Ā Ā 1) pick the newer post over the other
Ā Ā 2) break from specification and not lowercase hashes
Ā Ā 3) secretly associate canonical urls or additional entropy with post hashes in the backend without a sizeable performance impact somehow

Hmm, gnu.org is slow as heck. Shorter HTML pages load in about ten seconds. This complete AWK manual all in one large HTML page took a full minute: https://www.gnu.org/software/gawk/manual/gawk.html Is there maybe some anti AI shenanigans going on?

In any case, I find the user guide super interesting. My AWK skills are basically non-existent, so I finally decided to change that. This document is incredibly well written and makes it really fun to keep reading and learning. Iā€™m very impressed. So far, I made it to section 1.6, happy to continue.

Iā€™ve got a prototype of my hardcopy simulator going. Iā€™m typing on the keyboard and the ā€œdisplayā€ goes to the printer:

https://movq.de/v/56feb53912/s.png

https://movq.de/v/235c1eabac/MVI_8810.MOV.mp4

The biiiiiiiiiig problem is that the print head and plastic cover make it impossible to see whatā€™s currently being printed, because this is not a typewriter. This means: In order to see what I just entered, I have to feed the paper back and forth and back and forth ā€¦ itā€™s not ideal.

I got that idea of moving back/forth from Drew DeVault, who ā€“ as it turned out ā€“ did something similar a few years back. (I tried hard to read as little as possible of his blog post, because figuring things out myself is more fun. But that could mean I missed a great idea here or there.)

But hey, at least this is running on my Pentium 133 on SuSE Linux 6.4, printer connected with a parallel cable. šŸ˜

(Also, yes, you can see the printouts of earlier tests and, yes, I used ed(1) wrong at one point. šŸ¤Ŗ And ls insisted on using colors ā€¦)

@lyse@lyse.isobeef.org Oh, huh, maybe it was just my GNOME 2 themes back then that didnā€™t show the icon. šŸ¤”

I like the looks of your window manager. Thatā€™s using Wayland, right?

Oh, no. Itā€™s still X11. All my recent Wayland comments resulted from me trying to switch, but I think itā€™s still too early. Being unable to use QEMU (because it canā€™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 itā€™s probably not a priority for devs.

(Not to mention that I would have to fork and substantially extend dwl in order to ā€œreplicateā€ my X11 WM. And then, after having done that, Iā€™d have to follow upstream Wayland development, for which I donā€™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. Iā€™ve been using tiling WMs for ~15 years now, so itā€™s actually kind of refreshing to see something different for a change. šŸ˜…

Probably close to the older Windowses.

That particular theme is a ripoff of OS/2 Warp 3: https://movq.de/v/6c2a948882/s.png šŸ˜…

This drives me nuts when my workmates share their screens. I really donā€™t get it how people can work like that. You canā€™t even read the whole line in the IDE or log viewer with all the expanded side bars. And then thereā€™s 200 pixels on the left and another 300 pixels on the right where the desktop wallpaper shows. Gnaa! Thereā€™s the other extreme end when somebody shares their ultra wide screen and I just have a ā€œregularishā€ 16:10 monitor and donā€™t see shit, because itā€™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 doesnā€™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.

Hereā€™s an example of X11/Xlib being old and archaic.

X11 knows the data type ā€œcardinalā€. For example, the window property _NET_WM_ICON (which holds image data for icons) is an array of ā€œcardinalā€. I am already not really familiar with that word and Iā€™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 ā€œintegerā€ today.

EWMH says that icons are arrays of cardinals and that theyā€™re 32-bit numbers:

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

So itā€™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, youā€™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 didnā€™t exist, yet.

And this is something that I wouldnā€™t know how to fix without breaking clients.

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€¦
