@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.

@thecanine@twtxt.net That’s cute. 😃 (Why Clippy, though? 😅)

@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.

Should I go on a tour with these hot air balloons some day? Not sure if it’s scary as hell. 😂

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 Aww, yeah. 😍 (Reminds me, I haven’t paid attention to the sunset in quite a while …)

@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.

Here’s an interesting thought/angle on this topic:

A further check showed that all the network blocks are owned by one organization—Tencent [4]. I’m seriously thinking that the CCP (Chinese Communist Party) encourage this with maybe the hope of externalizing the cost of the Great Firewall [5] to the rest of the world.

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! 😅)

@lyse@lyse.isobeef.org @prologic@twtxt.net It’s too real, isn’t it? 🤣

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 …

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:

@kat@yarn.girlonthemoon.xyz Oh no. 😨 Backups! We need more backups!

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.

@bender@twtxt.net This should be a core feature, no configuration required. 🤔

@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.

@arne@uplegger.eu lol 😅

@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

Speaking of manpages:

“Man pages are great, man readers are the problem”

https://whynothugo.nl/journal/2025/04/09/man-pages-are-great-man-readers-are-the-problem/

mandoc is nicer to read/write than the man macro package and, most importantly, it’s semantic markup.

HTML output is a bit broken in GNU groff, though (OpenBSD on the left, GNU on the right):

Still, I’m inclined to convert my manpages to mandoc.

@kiwu@twtxt.net Hello. 😅

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.)

I wasn’t really aware until recently that programs can’t choose their own window’s position on Wayland. This is very weird to me, because this was not an issue on X11 to begin with: X11 programs can request a certain position and size, but the X11 WM ultimately decides if that request is being honored or not. And users can configure that.

But apparently, this whole thing is a heated debate in the Wayland world. 🤔
