Small but mighty news for UNIX fans:
GNU ed 1.22 is out! Now you can filter specific line ranges through shell commands directly in ed, ex(1)-style:

1,10!sort
Just like in ex or sed, this filters addressed lines through your favorite shell tools a great upgrade for scripting and editing workflows.

Even better: Today’s batch of Slackware -current updates already includes ed 1.22. If you’re running -current and up to date, you already have the new version!

Just released: #swad v0.3!

https://github.com/Zirias/swad/releases/tag/v0.3

swad is the "Simple Web Authentication Daemon", your tiny, efficient and (almost) dependency-free solution to add #cookie + login #form #authentication to whatever your #reverse #proxy offers. It's written in pure #C, portable across #POSIX platforms. It's designed with #nginx' 'auth_request' in mind, example configurations are included.

This release brings a file-based credential checker in addition to the already existing one using #PAM. Also lots of improvements, see details in the release notes.

I finally added complete build instructions to the README.md:

https://github.com/Zirias/swad

And there's more documentation available: manpages as well as a fully commented example configuration file.

The DVD is a rewritable type, as indicated by the "DVD-RW" marking. The disc also has "1.4X" and "4.7" printed on it, likely referring to the disc's speed and capacity. The DVD is encased in a clear plastic holder, and the background has a red hue, possibly from lighting. The DVD shows signs of wear, with visible scratches and scuffs.

I've encountered an annoying problem

A critical shared Library that's used by FFMpeg and of course also used by MPlayer was not in the installation. It was an odd because even a remove reinstall of FFMpeg didn't fix the problem.

Since I'm in no mood to install a development environment from the command line to compile FFMpeg from scratch I just wiped the KDE distro and started all over.

While I was busy with the new installation so I was on the live ISO FFMPEG worked just fine and the library was there working perfectly.

You can already guess what happened when I booted into the new installation.

FFMPEG was installed by default by the distribution, since VLC is installed by default, but the shared library was missing!

¡WTF!

Then I encountered even more bugs, privilege escalation errors!

These bugs and errors have nothing to do with KDE!

They have to do with problems with the distribution from the perspective of my maintainer. It is my task to see if I can reproduce the problems after I fix them by hand if that does not take too much time and effort.

Sometimes micro migration failures bring blessings, I learned how to use

xfce4-screenshooter -S -d 2 --window -s "$HOME/Pictures/$(date +%Y-%m-%d_%H-%M-%S)_Screenshot2.png"

from the commandline because it started to fail to add the date to the screencaps after the migration on my main MX linux install which is XFce4 based

This sequence also opens a thunar window sorted to date with the screencap. Of course the sorting is previously configured in thunar

The next step was to config KDE connect in this KDE. Luckily I know that I need gufw to migrate my profile, from the xFce MX linux to this KDE MX linux.
It was a matter of installing gufw, which is not default in KDE distro, since it has its own nice interface. For me sticking with what I know is the easiest since I want to drive KDE on desktop again after so many decades, even though XFce is still going to be used most, due to shortcut muscle memory

Today, I implemented the #async / #await pattern (as known from #csharp and meanwhile quite some other languages) ...

... in good old #C! 😎

Well, at least sort of.

* It requires some standard library support, namely #POSIX user context switching with #getcontext and friends, which was deprecated in POSIX-1.2008. But it's still available on many systems, including #FreeBSD, #NetBSD, #Linux (with #glibc). It's NOT available e.g. on #OpenBSD, or Linux with some alternative libc.

* I can't do anything about the basic language syntax, so some boilerplate comes with using it.

* It has some overhead (room for extra stacks, even extra syscalls as getcontext unfortunately also always saves/restores the signal mask)

But then ... async/await in C! 🥳

Here are the docs:
https://zirias.github.io/poser/api/latest/class_p_s_c___async_task.html

I finally eliminated the need for a dedicated #thread controlling the pam helper #process in #swad. 🥳

The building block that was still missing from #poser was a way to await some async I/O task performed on the main thread from a worker thread. So I added a class to allow exactly that. The naive implementation just signals the main thread to carry out the requested task and then waits on a #semaphore for completion, which of course blocks the worker thread.

Turns out we can actually do better, reaching similar functionality like e.g. #async / #await in C#: Release the worker thread to do other jobs while waiting. The key to this is user context switching support like offered by #POSIX-1.2001 #getcontext and friends. Unfortunately it was deprecated in POSIX-1.2008 without an obvious replacement (the docs basically say "use threads", which doesn't work for my scenario), but still lots of systems provide it, e.g. #FreeBSD, #NetBSD, #Linux (with #glibc) ...

The posercore lib now offers both implementations, prefering to use user context switching if available. It comes at a price: Every thread job now needs its private stack space (I allocated 64kiB there for now), and of course the switching takes some time as well, but that's very likely better than leaving a task idle waiting. And there's a restriction, resuming must still happen on the same thread that called the "await", so if this thread is currently busy, we have to wait a little bit longer. I still think it's a very nice solution. 😎

In any case, the code for the PAM credential checker module looks much cleaner now (the await "magic" happens on line 174):

The subject is fonts and the section is point size. The monitors I use are not of a small resolution. In fact an ideal IPS LED panel layout for me would be an 8K panel two 4K panels flanking it and two 1080p ultra ultra wide panels at a left and right of those.

With such a setup I can monitor different machines at the glance and control them with ease.

Even on my 1080p Ultra Ultra wide panel the default Point sizes for fonts are too small. On a scratch KDE based MX Linux installation, the following problem was repeated twice in Konsole.

The first time I changed font point sizes, closed konsole. When I reopened konsole the fixed with font, was replaced with one that appended spaces behind every couple of letters.

This rendered konsole unusable for work.

Changing the fonts Point sizes to the defaults again did not fix the problem.
Sinds that installation was Vanilla and didn't have enough space for home and root on one partition to actually Play with KDE, I wiped it and started again.

This time I deliberately did not change the point sizes even though it was hard to read. I then copied over some configuration directories from my other installation to this One, none of them related to anything KDE wise or any fonts directory. When I rebooted that installation The problem occurred for the second Time.

As with the wallpaper issue, I immediately converted that energy of irritation to something positive. I troubleshooted the font problem for a short while and when I couldn't isolate it I did a simple thing. I created a couple of other accounts on the same KDE installation to see if I could repeat the error.

That reproduction step is vital before a bug report is created. The other accounts were also residing on my other xFace MX Linux installations, which means I could simply copy them over to the other home partition where KDE was looking at.

In the other accounts I could not repeat the error.

That means a bug report is worthless because repeatability is crucial. Since the usage of a terminal in the K Desktop Environment is important, I changed my strategy and simply installed the xFace Four terminal in KDE. In the end that was a nice move since I know all the keyboard shortcuts of the terminal by hand they are in muscle memory and they have been there for years.

As a bonus I also installed other good shells in MX KDE the hashtags tell you which.

Right now I have a KDE installation in which I can actually work based upon the MX Linux KDE variant

You can use these tips to do it with activities, because those are good to learn too in KDE

I have 16 desktops on multiple IPS LED panels so for me that's not an option

My next step was something unexpected.

In XFce4 my desktops all have different backgrounds per IPS Led Panel. Its a matter of context_menu_key (on my keyboard I have one) select background, then move the program to the next display beside it and repeat, then move it to the next desktop, display besides AD Infinitum

KDE says HELL NO to that ease.
I did some reasearch and saw that it was easy peasy in KDE 4.5.x then got replaced with activities in KDE Plasma 5.x
The simple command is now either kwin scripts or a lot of keystrokes and time.

Instead of getting pissed I went further and found that what the programmers replaced with activities (which are POWERFULL and versatile) and also usuable for wallpapers per VTop (Virtual desktop) was eased back (in 2022) with VallPaper

What I still need to do is find out again where I can configure custom shortcuts to quickly switch between desktops using the keyboard
