[$] Cache awareness for the CPU scheduler
The kernel’s CPU scheduler has to balance a wide range of objectives. The
tasks in the system must be scheduled fairly, with latency for any given
task kept within bounds. All of the CPUs in the system should be kept busy
if there is enough work to do, but unneeded CPUs should be shut down to
reduce power consumption. A task should also run on the CPU that is most
likely to have cached the memory that task is using. [This patch\

Why performance optimization is hard work
Comments ⌘ Read more

@prologic@twtxt.net Yesterday Spain, Portugal, maybe Morocco, were without electricity for 12 hours. I could not work. My home server was down, my feed and pages were online because of that 😂

@movq@www.uninformativ.de Agreed, finding the right motivation can be tricky. You sometimes have to torture yourself in order to later then realize, yeah, that was actually totally worth it. It’s often hard.

I think if you find a project or goal in general that these kids want to achieve, that is the best and maybe only choice with a good chance of positive outcome. I don’t know, like building a price scraper, a weather station or whatever. Yeah, these are already too advanced if they never programmed, but you get the idea. If they have something they want to build for themselves for their private life, that can be a great motivator I’ve experienced. Or you could assign ‘em the task to build their own twtxt client if they don’t have any own suitable ideas. :-)

Showing them that you do a lot of your daily work in the shell can maybe also help to get them interested in text-based boring stuff. Or at least break the ice. Lead by example. The more I think about it, the more I believe this to be very important. That’s how I still learn and improve from my favorite workmate today in general. Which I’m very thankful of.

We’re all old farts. When we started, there weren’t a lot of options. But today? I’d be completely overwhelmed, I think.

Hence, I’d recommend to start programming with a console program. As for the language, not sure. But Python is probably a good choice

That’s what I usually do (when we have young people at work who never really programmed before), but it doesn’t really “hit” them. They’ve seen so much, crazy graphics, web pages, it’s all fancy. Just some text output is utterly boring these days. ☹️ And that’s my problem: I have no idea how I could possibly spark some interest in things like pointers or something “low-level” like that. And I truly believe that you need to understand things like pointers in order to program, in general.

@news-minimalist@feeds.twtxt.net so many “good news”, we are “winning” big time. I listen to NPR on my way to work, and they were talking about the foot depletion. You could hear the desperation of the people they put on, so incredibly sad. 😢

I had Chick-fil-A breakfast today (sausage, egg, and cheese biscuit, hash browns, coffee, and orange juice). Then at lunch my work place offered hot dogs. I had two (kosher, if that matters), plus a coke, a macadamia nuts cookie, and a small chocolate brownie.

So, here I am, at home, feeling hungry but guilty and refusing to eat anything else for the rest of the day. To top it off, I have only clocked 4,000 steps today (and I don’t feel like walking). I am going to hell, am I?

My Hypothesis for why registries didn’t work and why they still won’t really work today is because the bend the rules of “true” decentralization a bit. Users have to pick one or more registries to “register” to. Why would they want to do this? What is their incentive to do so? Then on the other hand, users need a client that has registry support, but now which registry or sets of registries do you choose?

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:

Image

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.

We had some nice 22°C today. But after work, it got rather windy and cloudy, temps rapidly dropped so just 14°C. Still a nice stroll to our backyard mountain. https://lyse.isobeef.org/waldspaziergang-2025-04-16/

and i felt SO BAD because i worried i was straining their service or something so i disabled my 4 tunnels (they were serving little SSH games and services) and got back to them.

but i just woke up to THE NICEST EMAIL EVER reassuring me that i was actually using it as intended, it was just my script that was having problems, and they even said that if it was intended to work that way it was fine and they just wanted to let me know!

so i restarted the tunnels but have since added lockfiles as safeguards so that when the script is run it’ll check if it’s already running :D

[$] Using large folios for text areas
Quite a bit of work has been done in recent years to allow the kernel to
make more use of large folios. That progress has not yet reached the
handling of text (executable code) areas, though. During the
memory-management track of the 2025 Linux Storage, Filesystem,
Memory-Management, and BPF Summit, Ryan Roberts ran a session on how that
situation might be improved. It would be a relatively small and contained
operation, but can give a measurable performance improvement. ⌘ Read more

[$] Per-CPU memory for user space
The kernel makes extensive use of per-CPU data as a way to avoid contention
between processors and improve scalability. Using the same technique in
user space is harder, though, since there is little control over which CPU
a process may be running on at any given time. That hasn’t stopped Mathieu
Desnoyers from trying, though; in the memory-management track of the 2025
Linux Storage, Filesystem, Memory-Management, and BPF Summit, he presented
a proposal for how user-space per-CPU memory could work. ⌘ Read more

Sometimes, we spend months stuck in inertia, distracted by screens and routine. So I’d like to give you a simple reminder: creating-in whatever form-is what makes you feel alive.

The beauty of working on projects is not in their ‘success’, but in the simple act of working on them. Whether it’s writing, cooking, programming or redecorating the house: play with ideas without pressure, engage in an activity to test, fail and discover without judgement.

In the end, what remains is not a perfect product, but the satisfaction of completion and valuable lessons.

Find a project, no matter how small, and let it take you without expectations.
