The lack of suckless-like simple, hackable software these days is appalling.

@prologic@twtxt.net Yeah, this really could use a proper definition or a “manifest”. 😅 Many of these ideas are not very wide spread. And I haven’t come across similar projects in all these years.
Let’s take the farbfeld image format as an example again. I think this captures the “spirit” quite well, because this isn’t even about code.
This is the entire farbfeld spec:
farbfeld is a lossless image format which is easy to parse, pipe and compress. It has the following format:
╔════════╤═════════════════════════════════════════════════════════╗
║ Bytes │ Description ║
╠════════╪═════════════════════════════════════════════════════════╣
║ 8 │ "farbfeld" magic value ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4 │ 32-Bit BE unsigned integer (width) ║
╟────────┼─────────────────────────────────────────────────────────╢
║ 4 │ 32-Bit BE unsigned integer (height) ║
╟────────┼─────────────────────────────────────────────────────────╢
║ [2222] │ 4x16-Bit BE unsigned integers [RGBA] / pixel, row-major ║
╚════════╧═════════════════════════════════════════════════════════╝
The RGB-data should be sRGB for best interoperability and not alpha-premultiplied.
(Now, I don’t know if your screen reader can work with this. Let me know if it doesn’t.)
I think these are some of the properties worth mentioning:
- The spec is extremely short. You can read this in under a minute and fully understand it. That alone is gold.
- There are no “knobs”: It’s just a single version, it’s not like there’s also an 8-bit color depth version and one for 16-bit and one for extra large images and one that supports layers and so on. This makes it much easier to implement a fully compliant program.
- Despite being so simple, it’s useful. I’ve used it in various programs, like my window manager, my status bars, some toy programs like “tuxeyes” (an Xeyes variant), or Advent of Code.
- The format does not include compression because it doesn’t need to. Just use something like bzip2 to get file sizes similar to PNG.
- It doesn’t cover every use case under the sun, but it does cover the most important ones (imho). They have discussed using something other than RGBA and decided it’s not worth the trouble.
- They refrained from adding extra baggage like metadata. It would have needlessly complicated things.

OH, FUCK ME DEAD! On the way home from today's walk I saw easily 800 fireflies! Yes, over eight hundred! That was absolutely amazing. First time this year and already this many. Crazy! They were just fricking everywhere in the entire forest. I counted to one hundred and then stopped. The darker it got, the more fireflies came out and glowed around. :-) There were spots where in under ten seconds I counted 20 glowworms. Super sick. Soooo beautiful. <3

I didn’t manage to leave the house yesterday. But when I went into the woods this evening, activity first was 10% of what it had been the day before yesterday. By the end it got a lot busier, about 50% of last time I reckon. Around 500 fireflies I’d imagine. I might have been faster than the days before. When I left the forest, I was right in the fog, that was cool.
Shortly after, I saw another lightshow. Right behind the Wasserberghaus somewhere on the Swabian Alp there was very crazy heat lightning every 5-10 seconds. That looked absolutely amazing. :-)

“A coalition of determined open-source software (OSS) advocates and a handful of technology experts working in the European Commission set out in 2004 to end Microsoft’s monopoly. They almost succeeded. This article reveals how they managed to change the EU’s software policies, made Microsoft lobbyists work overtime - and in the end, and despite their best efforts, could not withstand the power of proprietary companies’ lobbying campaigns.
Drawing on the Multiple Streams Framework, the article explains the European Commission’s decision to promote OSS and open standards in 2004, and its puzzling decision to reverse course just a few years later, in 2010, despite its unchanged rhetoric about the benefits of openness. The analysis reveals three key factors that drove the changes in the EU’s policies.
In 2004, OSS advocates managed to frame the EU’s dependency on proprietary software as a problem – and the promotion of OSS and open standards as the solution.
In 2010, #Microsoft and other proprietary companies used their existing connections in Brussels to sow doubt about the maturity and cost of #OSS among #EU policymakers.”

Buying a TV these days, means trying to avoid endless enshitification:
-Spyware and adware
-Shitty AI upscaling/ frame interpolation
-HW that breaks after 2 - 3 years
-One off OS, dead on arrival
-Android OS, that starts lagging after the third update
-8 buttons worth of ads, on your remote
You probably have to make some kind of a compromise. I thought that was buying from some other brand like Hyundai, but that one also felt into some of those categories and just broke, after less than 3 years of use. At this point I’ll probably go back to LG and hope their HW is still reliable and the rest manageable… It has AI bullshit and knowing LG, probably some spyware you have to try your best to get rid of, can buy a remote with “only” 2 ads on it, some web-based OS shared between all their TVs, that usually gets 4 - 5 years worth of updates and works decently enough afterwards.
At this point, I’ll probably settle for anything that doesn’t literally fall apart, not even 3 years in, like the Hyundai did.

@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. 😅

[$] The problem of unnecessary readahead
The final session in the memory-management track of the 2025 Linux Storage,
Filesystem, Memory-Management, and BPF Summit was a brief, last-minute
addition run by Kalesh Singh. The kernel’s readahead mechanism is
generally good for performance; it ensures that data is present by the time
an application gets around to asking for it. Sometimes, though, readahead
can go a little too far. ⌘ Read more
[$] Tracepoints for the VFS?
Adding tracepoints to some kernel subsystems has been controversial—or
disallowed—due to concerns about the user-space\
ABI that they might create. The virtual filesystem (VFS) layer has
long been one of the subsystems that has not allowed any tracepoints, but
that may be changing. At the 2025 Linux Storage, Filesystem, Memory
Management, and BPF Summit (LSFMM+BPF), Ted Ts’o led a discussion about
whether the ABI concerns are outweighed by the utility of tracepoints for … ⌘ Read more
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:
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.
[$] What’s new in APT 3.0
Debian’s Advanced Package Tool (APT) is the suite of utilities that handle package
management on Debian and Debian-derived operating systems. APT recently received a
major upgrade to 3.0 just in time for inclusion in Debian 13
(“trixie”), which is planned for release sometime in 2025. The version bump is
warranted; the latest APT has user-interface improvements, switches to [Sequoia](https://sequoia-pgp.org/pr … ⌘ Read more
[$] Parallel directory operations
Allowing directories to be modified in parallel was the topic of Jeff
Layton’s filesystem-track session at the 2025 Linux Storage, Filesystem,
Memory Management, and BPF Summit (LSFMM+BPF). There are certain use
cases, including for the NFS and Lustre filesystems, as mentioned in a patch set
referenced in the topic\
proposal, where contention in cre … ⌘ Read more

[$] Improvements for the contiguous memory allocator
As a system runs, its memory becomes fragmented; it does not take long
before the allocation of large, physically contiguous memory ranges becomes
difficult or impossible. The contiguous memory\
allocator (CMA) is a kernel subsystem that attempts to address this
problem, but it has never worked as well as some would like. Two sessions
in the memory-management track at the 2025 Linux Storage, Filesystem,
Memory-Management, and BPF Summit looked at … ⌘ Read more
