[$] Using dma-bufs for read and write operations

The kernel's dma-buf subsystem provides a way for drivers to share memory buffers, usually in order to support efficient device-to-device I/O. At the 2026 Linux Storage, Filesyste [...]

Interesting. It seems like there are way more Linux users here than I expected.

So, let’s do a little roll call:

What are you using?

Linux?
Windows?
macOS?
BSD?
Something beautifully weird?

I’m curious 👀

Security updates for Monday

https://lwn.net/Articles/1072301/ #LWN #Linux #security

If anyone wants to recruit a senior R&D code monkey with multiple degrees for a job that will involve neither "AI" bullshit nor "blockchain" bullshit nor "HFT" bullshit nor killing people nor destroying the planet just for the heck of it ... I get cheaper and cheaper by the minute as things descend deeper and deeper into nutty "More cloud and more AI will fix it!!" chaos around me. Located in Germany. Will only work remote as we're tied to this place due to aging parental units. Strong preference for something related to actual green technology such as solar. #FediHire #FediHired #Systems #Storage #ProgrammingLanguages #Compilers #GreenTech #Solar #Linux #BSD #Academia #Teaching #noAI #BoostsWelcome

So. After deleting and rebuilding my `ESP`partition I don't even know how many times and trying out so many different ways of setting up either #rEFind or #GRUB and messing with the `mkinitcpio.d/linux.preset` files, I finally got my original #Arch partition and new #Artix partition booting.

I could not, for the life of me, figure out how to segregate the Arch and Artix boot loaders and initramfs. But since they appear to be the same, both being Arch under the hood...

#Linux

It'd be great if #GTK & #libadwaita's About dialogs had a property for "Months of support per version", which would check the app's running version against its "date" field in the AppData metainfo.xml and hide the "Website" & "Report an Issue" buttons if it's too old.

Thus upstream devs could avoid being the externalized cost of free "LTS" distros (users reporting issues about ancient versions) without being accused of being anti #FLOSS (like in https://gitlab.com/linuxmint/pins/mint/gnome-calendar/-/work_items/1)

@DJDarren yes, it's true, Linux is not an operating system designed for the masses. Personally I would go with MS Windows. I like not having to know anything.

Linux is only good if you are doing software #development, or other types of boring work. Then it's your go-to system. If you need the #BASH terminal all the time, use it. If you almost never need it, use #Windows.

The worst thing about #Linux is that it doesn't have #MSPaint and #Notepad.

Do you hate yourself and despise convenience?

Then why not try Linux?

Episode 16 of Dark Blue Weekly released

Until now I've never bothered to look into the internals of keyboard software support and whatnot, but for a long time I somehow put up with #Alpine #Linux (or maybe it was a #KDE / #Wayland issue?) not enabling by default key repeat - or however you call holding a button and have it register as continuous holding instead of a single press.

Lo and behold, on #OpenBSD that just works (I just passed by the conf where key repeat is explicitly defined, so you know real people put real effort into this system). On the other hand, changing the language on my keyboard when using cwm instead of something like KDE?...

setxkbmap -layout ro does not output an error, but still doesn't mean it actually switched me to Romanian (however, something like French actually just works). wsconsctl keyboard.encoding=ro outputs the error that ro is not a valid encoding. According to the documentation, encodings are apparently listed in /usr/include/dev/wscons/wsksymdef.h - and indeed, there seems to be no "ro" in there. Changing locale didn't seem to help either.

Then I took a deep dive into the man page of wsconsctl(8). There it says: "The current mapping can be printed with wsconsctl keyboard.map. The value for each keycode specifies the keysym that is output when each of Key, Shift + Key, AltGr + Key, or Shift + AltGr + Key is pressed" A magic thing then happens... I test wsconsctl keyboard.map+="keycode 15 = l L at" - afterwards, I see in the keyboard mapping "l L at at"; the output is a Polish l=L with slash. I decide to test AltGr with every other key on my keyboard...

I burst into laughter when I realized that I do have now Romanian characters: they were hidden in plain sight, usable with AltGr as modifier. I can't seem to spot them in keyboard.map, where according to the documentation all keysyms should be specified. Maybe setxbkmap did the magic on top? At least I am grateful I can type ăâșîț and not have to copy paste the characters.

The update/reboot operation via Software is the same operation as the update/upgrade operation in the #Terminal.

You can tell because the prompt to update/reboot disappears if you apt update/upgrade instead.

(Or at least, that's what it does in Debian.

Neato.

I just noticed something in #Linux that is, I'm sure, totally obvious to experts but that I didn't know.

If you sudo apt update/upgrade, then you don't have do updates in the Software centre that require a reboot.
