That’s what I’m using right now, while my own client is still in the making.

A simple bash script to write a post in a mktemp file then clean it with regex.
I don’t even bother to hash the replies, I just open https://twtxt.net and copy the hash by hand since I’m checking the new posts from there anyway (temporarily, as I might end up DoS-ing everyone’s feed in my client right now).

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 …

Just discovered how easy it is to recall my last arg in shell and my brain went 🤯 How come I’ve never learned about this before!? I wonder how many other QOL shortcuts I’m missing on 🥲

Even though I really do like the shell, I always use Dolphin to mount my digicam SD card and copy the photos onto my computer. I finally added a context menu item in Dolphin to create a forest stroll directory with the current date in order to save some typing:

Image

The following goes in ~/.local/share/kservices5/ServiceMenus/galmkdir.desktop:

[Desktop Entry]
Type=Service
X-KDE-ServiceTypes=KonqPopupMenu/Plugin,inode/directory
Actions=Waldspaziergang;

[Desktop Action Waldspaziergang]
Name=Heutigen Waldspaziergang anlegen…
Icon=folder-green
Exec=~/src/gelbariab/galmkdir "%f"

In order to update the KDE desktop cache and make this action menu item available in Dolphin, I ran:

kbuildsycoca5

The referenced galmkdir script looks like that:

#!/bin/sh
set -e

current_dir="$1"
if [ -z "$current_dir" ]; then
    echo "Usage: $0 DIRECTORY" >&2
    exit 1
fi

dir="$(kdialog \
    --geometry 350x50 \
    --title "Heutigen Waldspaziergang anlegen" \
    --inputbox "Neues Verzeichnis in „$current_dir“ anlegen:" \
    "waldspaziergang-$(date +%Y-%m-%d)")"
mkdir "$current_dir/$dir"
dolphin "$current_dir/$dir"

This solution is far from perfect, though. Ideally, I’d love to have it in the “Create New” menu instead of the “Actions” menu. But that doesn’t really work. I cannot define a default directory name, not to mention even a dynamic one with the current date. (I would have to update the .desktop file every day or so.) I also failed to create an empty directory. I somehow managed to create a directory with some other templates in it for some reason I do not really understand.

Let’s see how that works out in the next days. If I like it, I might define a few more default directory names.

AI problems, top to bottom:

1: Open AI nerds, believe fine tuning a language model algorithm, will eventually produce an AGI god.

2: Subpar artists and techbros who can’t code, convinced AI image bashing and vibe coding, will help convince the dumber parts of Internet, they are a real deal.

3: Parasites, using AI to scam people, because they just want passive income, selling crap, made by an automated process.

Side: Adobe&co, killing Flash/old web, pricing new artists and developers out, to face learning curves of free tools, or use AI, peddled as solution.

Then I cleaned up my shell history of all of the invocations I ever made of dkv rm ... to make sure I never ever have this so easily accessible in my shell history (^R):

  /^#/ { ts = $0; next }
  /^dkv rm/ { next }
  { if (ts) print ts; ts=""; print }
' ~/.bash_history > ~/.bash_history.tmp && mv ~/.bash_history.tmp ~/.bash_history && history -r

My previous post included a video. I made that video with OBS which outputs .mkv video files.

My hypothesis about that thing breaking my twts is that it might have something to do with the parenthesis surrounding the root twt hash in the replay twt-A when I replay to it with fork-twt-B; I imagine elisp interpreting those as a s-expression thus breaking the generation precess of hash (#twt-A) before prepending it to for-twt-B … but then I’m too ignorant to figure out how to test my theory (heck I couldn’t even recalculate the hashes myself correctly in bash xD). I’ll keep trying tho.

@aelaraji@aelaraji.com this is the little script I am using on my publish_command:

#!/usr/bin/env bash

twtxt2html -t "Quark's twtxt feed" /var/www/sites/ferengi.one/twtxt.txt > /var/www/sites/ferengi.one/index.html

I named it twtxtit. :-)

@bender@twtxt.net It’s just a simple twtxt2html and scp … it goes like:

twtxt2html $HOME/path/to/local_twtxt_dir/twtxt.txt > $HOME/path/to/local_twtxt_dir/log.html && \
scp $HOME/path/to/local_twtxt_dir/log.html user@remotehost:/path/to/static_files_dir/

I’ve been lazy to add it to my publish_command script, now I can just copy/pasta from the twt 😅

@movq@www.uninformativ.de Variable names used with -eq in [[ ]] are automatically expanded even without $ as explained in the “ARITHMETIC EVALUATION” section of the bash man page. Interesting. Trying this on OpenBSD’s ksh, it seems “set -u” doesn’t affect that substitution.

I love shell scripts because they’re so pragmatic and often allow me to get jobs done really quickly.

But sadly they’re full of pitfalls. Pitfalls everywhere you look.

Today, a coworker – who’s highly skilled, not a newbie by any means – ran into this:

$ bash -c 'set -u; foo=bar; if [[ "$foo" -eq "bar" ]]; then echo it matches; fi'
bash: line 1: bar: unbound variable

Why’s that happening? I know the answer. Do you? 😂

Stuff like that made me stop using shell scripts at work, unless they’re just 4 or 5 lines of absolutely trivial code. It’s now Python instead, even though the code is often much longer and clunkier, but at least people will understand it more easily and not trip over it when they make a tiny change.

Since I have these simple, yet effective bash shell commands, which allow me to edit notes, plans, todos and statuses from the terminal, I feel liberated from overly complex software - everything is just text files and applications which come preinstalled on every Linux system.

@prologic@twtxt.net I’ve even added the twthash message hash to my Twtxt bash CLI script so I can properly answer here.

@mdosch@mdosch.de Apple refuses to ship GPLv3 software. bash has security bugs that Apple doesn’t want to backport. So they’ve switched default shells again, this time to zsh. (bash and the previous default, tcsh, still ship with the OS.)

Interestingly enough, Visual Studio Code keeps running bash as its preferred shell, even though it isn’t the login shell anymore.
