Twts matching #linux

I’ve got a prototype of my hardcopy simulator going. I’m typing on the keyboard and the “display” 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 what’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 … it’s not ideal.

I got that idea of moving back/forth from Drew DeVault, who – as it turned out – 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. 😍

(Also, yes, you can see the printouts of earlier tests and, yes, I used ed(1) wrong at one point. 🤪 And ls insisted on using colors …)

In-reply-to » i'm helping someone get a reverse proxy going on windows and my god this operating system is dogshit

@kat@yarn.girlonthemoon.xyz yeah it’s pretty terrible these days. Most recent trouble I had was something as simple as installing and setting up the Tailscale client. On literally all my other devices (Linux and Android) that was a cinch, but on Windows…. ohh boy, I had to mess around with reg edits and all sorts of crap and eventually bludgeoned it into working, but it was a bloody pain.

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.

In 1996, they came up with the X11 “SECURITY” extension:

https://www.reddit.com/r/linux/comments/4w548u/what_is_up_with_the_x11_security_extension/

This is what could have (eventually) solved the security issues that we’re currently seeing with X11. Those issues are cited as one of the reasons for switching to Wayland.

That extension never took off. The person on reddit wonders why – I think it’s simple: Containers and sandboxes weren’t a thing in 1996. It hardly mattered if X11 was “insecure”. If you could run an X11 client, you probably already had access to the machine and could just do all kinds of other nasty things.

Today, sandboxing is a thing. Today, this matters.

I’ve heard so many times that “X11 is beyond fixable, it’s hopeless.” I don’t believe that. I believe that these problems are solveable with X11 and some devs have said “yeah, we could have kept working on it”. It’s that people don’t want to do it:

Why not extend the X server?

Because for the first time we have a realistic chance of not having to do that.

https://wayland.freedesktop.org/faq.html

I’m not in a position to judge the devs. Maybe the X.Org code really is so bad that you want to run away, screaming in horror. I don’t know.

But all this was a choice. I don’t buy the argument that we never would have gotten rid of things like core fonts.

All the toolkits and programs had to be ported to Wayland. A huge, still unfinished effort. If that was an acceptable thing to do, then it would have been acceptable to make an “X12” that keeps all the good things about X11, remains compatible where feasible, eliminates the problems, and requires some clients to be adjusted. (You could have still made “X11X12” like “XWayland” for actual legacy programs.)

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 True, at least old versions of KDE had icons:

https://movq.de/v/0e4af6fea1/s.png

GNOME, on the other hand, didn’t, at least to my old screenshots from 2007:

https://www.uninformativ.de/desktop/2007%2D05%2D25%2D%2Dgnome2%2Dlaptop.png

I switched to Linux in 2007 and no window manager I used since then had icons, apparently. Crazy. An icon-less existence for 18 years. (But yeah, everything is keyboard-driven here as well and there are no buttons here, either.)

Anyway, my draft is making progress:

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

This is it, boys and girls! The year of the Linux Desktop is this! I can smell it! :-D

For the first time, Linux has officially broken the 5% desktop market share barrier in the United States of America! It’s a huge milestone for open-source and our fantastic Linux community.

In-reply-to » I bought the “remastered” versions of Grim Fandango and Forsaken on GOG, because they’re super cheap at the moment. Both have native Linux versions.

In all fairness, GOG says that Forsaken is only supported on Ubuntu 16.04 – not current Arch Linux. If you ask me, this just goes to show that Linux is not a good platform for proprietary binary software.

Is it free software, do you have the source code? Then you’re good to go, things can be patched/updated (that can still be a lot of work). But proprietary binary blobs? Very bad idea.

I bought the “remastered” versions of Grim Fandango and Forsaken on GOG, because they’re super cheap at the moment. Both have native Linux versions.

And both these Linux version crap their pants. 🫤 The bundled SDL2 of Forsaken says it “can’t find a matching GLX visual” and I couldn’t figure out how to fix that. I didn’t spend a lot of time on Grim Fandango.

Both work great in Wine. 🤦

(I do have the original version of Grim Fandango from the 1990ies, but that one does not work so well in Wine. I figured, if it’s so cheap, why not. And I now get to play the english version. 😃 The german dub is pretty damn good, actually, but I always prefer the original these days.)

Speaking of Wine, Arch Linux completely fucked up Wine for me with the latest update.

  • 16-bit support is gone.
  • Performance of 3D games is horrible and unplayable.

Arch is shipping a WoW64 build now, which is not yet ready for prime time.

And then I realized that there’s actually only one stable Wine release per year but Arch has been shipping development releases all the time. That’s quite unusual. I’m used to Arch only shipping stable packages … huh.

Hopefully things will improve again. I’m not eager to build Wine from source. I’d rather ditch it and resort to my real Windows XP box for the little (retro)gaming that I do … 🫤

OpenBSD has the wonderful pledge() and unveil() syscalls:

https://www.youtube.com/watch?v=bXO6nelFt-E

Not only are they super useful (the program itself can drop privileges – like, it can initialize itself, read some files, whatever, and then tell the kernel that it will never do anything like that again; if it does, e.g. by being exploited through a bug, it gets killed by the kernel), but they are also extremely easy to use.

Imagine a server program with a connected socket in file descriptor 0. Before reading any data from the client, the program can do this:

unveil("/var/www/whatever", "r");
unveil(NULL, NULL);
pledge("stdio rpath", NULL);

Done. It’s now limited to reading files from that directory, communicating with the existing socket, stuff like that. But it cannot ever read any other files or exec() into something else.

I can’t wait for the day when we have something like this on Linux. There have been some attempts, but it’s not that easy. And it’s certainly not mainstream, yet.

I need to have a closer look at Linux’s Landlock soon (“soon”), but this is considerably more complicated than pledge()/unveil():

In-reply-to » Nobody want to be a shitty programmer. The question is: Do you do anything not to not be one? Reading blogs or social media and watching YouTube videos is fun. After them, your code may be a little better, of course. But you need a lot. You need to study! Read good books and study the code of other programmers, for example. Maybe work with a new language, architectures and paradigms. You need break the routine.

@andros@twtxt.andros.dev

You need break the routine.

I haven’t really done that lately. 🤔 Maybe have another go at Rust (given its increasing importance in the Linux kernel)? Or Elixir, yes, I only had some very, very brief contact with it. 🤔

I just came across an old forum posting of mine about Prolog. That brought up some memories. Prolog is pretty alien, but I do miss stuff like that because it’s so different.

Just thinking out loud here. 😅

@movq@www.uninformativ.de @kat@yarn.girlonthemoon.xyz @quark@ferengi.one In 2014 one person created protocol ii. Later it forked in IDEC. Why i said this? Because it’s simple “federated” forum-like protocol where from your station fetch another every 5-10 minutes. Stations has topic-based channels like idec.talks, linux.16, haiku.os, zx.spectrum. In short it’s FIDO but.. more modern? Documentation: https://github.com/idec-net/new-docs (mostly Russian, but you can use translator, also protocol already translated to english)

Confession:

I’ve never found microblogging like twtxt or the Fediverse or any other “modern” social media to be truly fulfilling/satisfying.

The reason is that it is focused so much on people. You follow this or that person, everybody spends time making a nice profile page, the posts are all very “ego-centric”. Seriously, it feels like everybody is on an ego-trip all the time (this is much worse on the Fediverse, not so much here on twtxt).

I miss the days of topic-based forums/groups. A Linux forum here, a forum about programming there, another one about a certain game. Stuff like that. That was really great – and it didn’t even suffer from the need to federate.

Sadly, most of these forums are dead now. Especially the nerds spend a lot of time on the Fediverse now and have abandoned forums almost completely.

On Mastodon, you can follow hashtags, which somewhat emulates a topic-based experience. But it’s not that great and the protocol isn’t meant to be used that way (just read the snac2 docs on this issue). And the concept of “likes” has eliminated lots of the actual user interaction. ☹️

The wonderful world of Linux package managers
One of the strong points of Linux has always been how solid the experience of installing and managing software is.

In-reply-to » @movq i tried ngircd but couldn't figure it out T__T i left it at the web client and bouncer for now but i might toy with an IRC server another time!

@kat@yarn.girlonthemoon.xyz At the core, you need an ngircd.conf like this:

[Global]
    Name = your.irc.server.com
    Password = yourfancypassword
    Listen = 0.0.0.0
    Ports = 6667

    AdminInfo1 = Well, me.
    AdminInfo2 = Over here!
    AdminEMail = forget.it@example.invalid

[Options]
    Ident = no
    PAM = no

[SSL]
    CertFile = /etc/ssl/acme/your.irc.server.com.fullchain.pem
    KeyFile = /etc/ssl/acme/private/your.irc.server.com.key
    DHFile = /etc/ngircd/dhparam.pem
    Ports = 6669

Start it and then you can connect on port 6667. (The SSL cert/key must be managed by an external tool, probably something like certbot or acme-client.)

I’m assuming OpenBSD here. Haven’t tried it on Linux lately, let alone Docker. 😅

@prologic@twtxt.net Since you have to check and double check everything it spits out (without providing sources), I don’t find any of this helpful. It’s like someone’s in the room with you and that person is saying random stuff that might or might not be correct. At best, it might spark some new idea in your head and then you follow that idea the traditional way.

Information published on the internet (or anywhere, for that matter) was never guaranteed to be correct. But at least you had a “frame of reference”: “Ah, I read this information about Linux on a blog that usually posts about Windows, so this one single Linux post might not necessarily be correct.” That is completely lost with LLMs. It’s literally all mushed together. 🤷
