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 …)

@prologic@twtxt.net @moveq@twtxt.net I think it’s mostly the serious lack of competition. All the Android phone manufacturers just use the Google version of Android, bundle in piles of Google bloatware and do whatever Google tells them to. If some of them installed Lineage, or any other versions, with their own stores and rules, or even just offer a less Googly version of their phones, as an option, for more experienced users, Google wouldn’t be able, to push everyone around.

@dce@hashnix.club I don’t use Gemini, but I follow you on the good, old, HTTP(S)! :-)

@movq@www.uninformativ.de @prologic@twtxt.net this is extremely concerning and I hope there is enough push back to stop this! The ability to modify apps, is one of the two biggest reasons, I’m still using Android. If they remove that option, I’ll be forced to switch to one of the de-Googled forks.

That might not be a good solution either, because I need banking and identity verification apps on my main device and already had to get a second device for work, which has tighter sideloading restrictions and I would very much not like to be forced into using three Android phones simultaneously, to do what should be possible, with just one.

@prologic@twtxt.net Anything above a couple hundred Euros. 😅 The current Epson LX-350 appears to be not that pricey, though. 🤔

I mean, what do you want to do with it? If you want to use this as an actual printer for daily use, I’d get a laser printer instead, because they’re very reliable and the print quality is top notch.

I got my dot matrix printer mostly for experiments and nostalgia, so I wouldn’t want to pay something like 300-400€ for it.

@prologic@twtxt.net Yeah, those POS thingies are similar. There’s “ESC/POS” as a variant of “ESC/P”, if I’m not mistaken.

All I can say is, when I go to big stores like Amazon, then I have trouble finding “traditional” dot matrix printers for use at home. 😅 Epson still sells them, but they’re more expensive than my laser printer was. So yeah, they still exist, just expensive, by the looks of it.

@prologic@twtxt.net Hmm, good question. I haven’t checked the market, I got mine from someone I know. But to be honest, I’d suspect that buying a used one is actually your best shot, because there is virtually no market for these devices anymore, meaning new ones are very, very expensive. 🫤

FWIW, I have an OKI Microline 3390eco. Good thing is, you can still buy new cartridges for it.

If you want to buy a new device, check if it supports the “ESC/P” standard. That’s very widely supported.

This is why I love tech from that era.

Write bytes to a parallel port and stuff happens. If it’s just ASCII bytes, then it will print ASCII text. Even the simplest programs can use a printer this way.

With a little bit of ESC/P, you can print images and other fancy stuff. That’s what I did this morning – never worked with ESC/P before, now I can print images. It’s not that hard.

Hayes-compatible modems are similar: Write some AT commands to the serial port and the modem does things. This isn’t even arcane knowledge, it’s explained in the printed manual.

Maybe I’m wearing rose-tinted glasses here, but I think with all this old stuff, you get useful results very quickly and the manuals are usually actually helpful. It’s so much easier to get started and to use this hardware to the full extent. Much less complexity than what we have today, not a ton of libraries and dependencies and SDKs and cloud services and what not.

@lyse@lyse.isobeef.org When/if I can pull it off, there will be videos! 😅

I never used hardcopy terminals, either. We did have a dotmatrix printer, but that was just used as a regular printer.

Inkjets, I don’t know. They were pretty fascinating and cool when they came out. A lot faster than dotmatrix and obviously quiter. They never gave me much trouble, actually. But I switched to a laser printer long before crap like DRM’ed ink cartridges became a thing.

@movq@www.uninformativ.de Heck yeah, have fun! :-) We never had a matrix printer, started off with a cathode ray tube and an inkjet pisser.

I’m happy to see you compose your first twtxt message using ed on your new output device. We definitely need video proof of that! ;-)

Sooooooooo, things happened, and I now have a dot matrix printer again. 😍😂

(One of the end goals is to simulate a hardcopy terminal on my old box. I’m waiting for another cable to arrive, I don’t have USB there. And then use ed(1) like it was meant to be used! 😅)

The GPG signatures of my software tarballs have been wrong for years (because I’ve been using rsync wrong, funny enough, it wasn’t a GPG issue) and nobody ever noticed. (They still are wrong at the moment, because I haven’t pushed the fix, yet.)

This confirms that this is just a total waste of time. Nobody ever checks this. Maybe this matters if you’re a distro, but why even bother as a single person …

@movq@www.uninformativ.de Ucycling just rocks to hard!

@lyse@lyse.isobeef.org ooooh! I wish I had that mallet here at work today. So many uses come to mind! 😂

@lyse@lyse.isobeef.org that’s so cool! I had to do some research, as I thought all pallets were made using cheap pine wood (which is quite soft), but, boy, as I erring big time! Oak it is also used, which is hardwood, and quite durable.

I use Headscale. Love it!

@movq@www.uninformativ.de Oh yeah, once in the quarter to the office is absolutely amazing and luxurious. Thank you teammates and employer! Though, I would already have been on site when these things happened earlier.

Today is my last day of holiday. Back to work again tomorrow. Not looking forward, vacation is just great. So easy to get used to.

Today I finally got rid of my /29 IPv4 subnet with my ISP used to power my ingress. No longer.

@movq@www.uninformativ.de having to go to a gopher proxy to see a text document better served on readily available web servers… 🤭, but I digress. Verbatim text:

What's Missing from "Retro"
~softwarepagan
------------------------------------------------------------------
You know, often, when I say I miss older ways of computing or
connecting online, people tell me "there's nothing stopping you
from doing that now!" and they are technicay correct in most cases
(though I can't, for example, chat with friends on MSN ever
again...) However, let me explain that while this type of thing can
*sort of* fill that hole in my heart, it isn't *the same.*

Say, for example, I wanted to connect with others over a BBS. This
wouldn't offer the same types of connections it used to. While
there are BBSes around with active users, they're no longer there
to discuss movies, Star Trek, D&D, games, etc. They're there to
discuss *BBSes.* The same can be said for Gopher, old-school forums
and all sorts of revival projects (such as Escargot, Spacehey,
etc.) Retrocomputing enthusiasts, while they have a variety of
interests, are often in these spaces to discuss the medium itself
and not other topics. This exists at a stark contrast from how
things were in the past, where a non-tech-inclined person may learn
the tech to connect with likeminded others (as I did as a
Zelda-obsessed kid.)

The same can be said of old media. People will say "well, nobody is
stopping you from watching old shows/movies now!" Again, they are
technically correct. I can go home right now and watch *Star Trek:
The Next Generation* to my heart's content. It will never again,
however, be current, or new. When something is new, it serves as a
shared cultural experience. Remember how "Game of Thrones* felt in
the mid-to-late 2010s? Yeah, that.

It's sad. I sustain myself on a mixed diet of old things, new
things, and new things intended for old millenials like me who like
old things. It can be bittersweet. 

We did an experiment at work today: Do I even need to lock my laptop when I’m gone or is nobody able to use it anyway?

It went as expected. 🤣

@kat@yarn.girlonthemoon.xyz If you’re willing to ignore that it’s proprietary software, then Windows used to be pretty good. Like, 25 years ago. After Windows 2000 (or maybe XP) it went downhill fast. Kind of makes me sad, actually. 😂

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:

https://salsa.debian.org/apt-team/apt/-/blob/main/doc/apt.ent?ref_type=heads#L17

Abstractions upon abstractions upon abstractions.

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:

https://movq.de/v/de5ab72016/s.png

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.

https://movq.de/v/394282ec75/s.png

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.

@kat@yarn.girlonthemoon.xyz Here’s the full config I use.

@lyse@lyse.isobeef.org @kat@yarn.girlonthemoon.xyz Colorized manpages have been a thing for a very long time:

https://movq.de/v/81219d7f7a/s.png

Problem is, hardly anybody knows this, because you configure this by … drumroll … overwriting TERMCAP entries of less in your ~/.bashrc:

export LESS_TERMCAP_md=$'\e[38;5;3m'      # Bold
    export LESS_TERMCAP_me=$'\e[0m'           # End Bold
export LESS_TERMCAP_us=$'\e[4;38;5;6m'    # Underline
    export LESS_TERMCAP_ue=$'\e[0m'           # End Underline
export GROFF_NO_SGR=1                     # Needed since groff 1.23

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).

@prologic@twtxt.net I’d expect a custom build like that to cost at least 50’000€ here in Europe. Used campers with 100’000 - 200’000 km already on their clock are 20-40k€, apparently. 😆

@prologic@twtxt.net Cool! What program do you use to draw this up?

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.

@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 😅

We ran some similar brownish color scheme (don’t recall its name) on Win95 or Win98

Oh god. Yeah, I wasn’t a fan of those, either. 🥴

@movq@www.uninformativ.de According to this screenshot, KDE still shows good old application icons: https://upload.wikimedia.org/wikipedia/commons/9/94/KDE_Plasma_5.21_Breeze_Twilight_screenshot.png

And GNOME used to have them, too: https://upload.wikimedia.org/wikipedia/commons/9/9f/Gnome-2-22_%284%29.png

I like the looks of your window manager. That’s using Wayland, right? The only thing on this screenshot to critique is all that wasted space of the windows not making use of the full screen!!!1 At least the file browser. 8-)

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. This brown one (https://www.uninformativ.de/blog/postings/2025-07-22/0/leafpads.png) gives me also classic vibes. Awww. We ran some similar brownish color scheme (don’t recall its name) on Win95 or Win98 for some time on the family computer. I remember other people visting us not liking these colors. :-D

@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:

https://movq.de/v/5b7767f245/s.png

I do like this look. 😊

@kat@yarn.girlonthemoon.xyz Cool! I just got an idea for work tomorrow: Use dmenu to quickly start different SSH tunnels I routinely need.

@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.

@movq@www.uninformativ.de @kat@yarn.girlonthemoon.xyz I’m just used to it because I deal with such things all the time. :-)

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. Thank you, much appreciated!

@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?

@lyse@lyse.isobeef.org yesss it’s not my idea but it’s sooo fun here ngl like i should use it more!!

@kat@yarn.girlonthemoon.xyz Nice use of dmenu.

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 GNOME’s dconf, which uses some binary file format. Fun fact: The older and now deprecated gconf also used XML files.)
