I certainly don't really need an introduction lol 🤣.
But for the ones who don't know me, my name is Stuart but you can call me Stu.
I am a very big fan of technology and music.
I also love fishing and playing golf ⛳.
I like all decentralized platforms and open source platforms.
These are some #'s I'm interested in:
I'm trying to add "genric" #signal handling to #poser. Ultimate goal is to provide a way for #swad to handle #SIGHUP, although signal handling must be done in poser's main event loop (signals are only ever unblocked while waiting for file descriptor events).
Okay, I could just add explicit handling for SIGHUP. But a generic solution would be nicer. Just for example, a consumer might be interested in #SIGINFO which doesn't even exist on all platforms ... 🤔
Now, #POSIX specs basically just say signal constants are "integer values". Not too helpful here. Is it safe to assume an upper bound for signal numbers on "real world" OS implementations, e.g. 64 like on #Linux? Should I check #NSIG and, if not defined, just define it to 64? 🙈
I use Zip Bombs to Protect my #Linux and #Unix Server from AI and other stupid bots https://idiallo.com/blog/zipbomb-protection
@annaleen I use Zathura for viewing PDFs, which is available at least on Linux on Mac.
Besides not bundling AI, there's no toolbar: All you see is the PDF.
There are some intuitive key commands for basic functions like page up, page down. Because it's minimal, launches very quickly and makes the most of smaller screens, like laptops.

Big thanks to Stefano Marinelli (@stefano@bsd.cafe),
our dedicated admin keeping BSD.cafe running smoothly.
Stefano is always such a positive presence, and his work
is the foundation of our feedverse home.
And a huge shoutout to The Real Grunfink (@grunfink@comam.es),
creator of the excellent #snac #ActivityPub server.
Snac truly embodies the KISS and minimalist principles – simple,
efficient, and powerful software that makes the Fediverse better.
These two contribute significantly to our online space.
If you value their efforts and the spirit of their work,
consider supporting them financially.
Every bit helps keep these vital parts of the decentralized web thriving.
Thank you, Stefano and Grunfink!

I wrote a book on Linux Memory Management, published by @nostarch - it's a comprehensive 1300 page exploration of Linux 6.0's memory management code, depth-first, diving into the code and REALLY explaining how things work.
The idea is to avoid hand waving as much as possible and literally explore what the kernel _actually_ does.
It's full of diagrams and careful explanations of logic including a ton of stuff you just can't find anywhere else.
It's currently available in its entirety in draft form via early access when you pre-order.
It's available at https://nostarch.com/linux-memory-manager

And yet it seems to be common practice nowadays to ask google how to do something, find a shell command on some arbitrary web site, and copy/paste it onto the local machine without ever understanding what it does.
If you're on a unix box and need to access the terminal (for any reason whatsoever) but don't know the basics of a shell (sh/bash/zsh/etc), you have a problem.
As for LLM, the only concern I would have is whether the `tmuxai` command can be assured to run the command it says it's running. I don't see any issue with `rm -i ./logs/debug-*.log`, especially with the `-i` flag present.
would you give LLM (AI) to run commands on your macOS, Linux, FreeBSD or Unix machine? Fuck no. I survived this long without this crap and I will be fine. Do not want. Go away.

Revisiting #async / #await in #POSIX C, trying to "add some #security" 🙈
Recap: Consider a classic #reactor-style service in C with a #threadpool attached to run the individual request handlers. When such a handler needs to do some I/O, it'll have to wait for its completion, and doing so is kind of straight forward by just blocking the worker thread executing the job until whatever I/O was needed completes.
Now, blocking a thread is never a great thing to do and I recently tooted about an interesting alternative I found: Make use of the (unfortunately deprecated) POSIX user context switching to enable releasing the worker thread while waiting. In a nutshell, you create a context with #makecontext that has its own private #stack, and then you can use #swapcontext to get off the thread, and later again to get back on the thread. A minor issue is: It must be the *same* thread ... so you might have to wait until it completes something else before you can resume your job. But then, that's probably okayish, you can make sure in your job scheduling to only use worker threads with awaited tasks attached when no other thread is available.
In my first implementation, I just used #malloc to create a 64kiB private stack for each thread job. That's perfectly fine if you can guarantee your job will never consume more stack space, AND it won't have any vulnerabilities allowing some attacker to mess with the stack. But in practice, especially for a library offering this async/await implementation, it's nothing but a wild #CVE generator.
So, I now improved on that:
* Allocate a much larger stack of now 2MiB. That alone makes issues at least less likely. And on a sane modern OS, we can still assume pages will only be mapped "on demand".
* Only allocate the stack directly before running the thread job, and delegate allocation to some internal "stack manager" that keeps track of all allocated stacks and reuses them, only freeing them on exit. This should avoid most of the allocation overhead.
* If MAP_ANON / MAP_ANONYMOUS is available, use #mmap for allocating the stack. That at least gives a chance to stay away from other allocations ....
* But finally, if MAP_STACK is available, use this flag! From my research, #FreeBSD, #OpenBSD and #NetBSD will for example make sure there's at least one "guard page" below a stack mapped with this flag, so a stack overflow consistently takes the SIGSEGV emergency exit 😆. #Linux knows this flag as well, but doesn't seem to implement such protection at this time ... 🤔

Schönen Tag Linux interessierte!
Ich fange an Videos über #Linux und #opensource zu erstellen. Diese sollen vor allem für Einsteiger gedacht sein. Allgemeine Themen werden auch mal drankommen. Vier Videos auf meinem #PeerTube und #YouTube Kanal gibt es schon, schaut dort gerne mal vorbei. Auf #Mastodon bin ich jetzt auch vertreten.

I would love to see more Linux desktop users, but people (mostly kids or gamers) who watch PewDiePie will not dump Windows because they want those AAA game titles and apps from Adobe and others unavailable on #Linux. Apps are the problem. I’ve been using Linux since the early days, and it is ready for many use cases, especially when privacy is your major concern. Otherwise, you should have the willpower to accept and learn alternative apps.
Regardless of PewDiePie’s personal #politics (which clearly, at the very least are problematic), it is fairly well known by anyone who has been following him for any number of years that the vast majority of his fan base are enthusiastic fascists.
Now #PewDiePie , who’s content centers around PC gaming and Windows, has decided to switch to #Linux and published a video encouraging his followers to do the same. This means a very large number of his #fascist fan base is going to be switching to Linux.
Now many Linux communities are going to be forced to more explicitly choose their politics. Like the parable of the Nazi bar, if the community remains politically neutral, it will become fascist in short order.
A few things to be wary of:
- People asking you not to be “too political” or to “focus on the technology, not the politics” is a classic and highly effective fascist ruse to get moderators to lighten up on fascist elements posting in their community.
- People complaining about free speech rights. The #Internet and the #Fediverse is already a domain where people can speak freely about their politics by running their own server and building their own community with few to no government constraints. You don’t need to compromise on whether fascists have the right to free speech in your community.
- Arguments over your code of conduct (CC) and “safe spaces.” Keep them up-to-date. Research other people’s CCs, learn about the history of why these CCs came to be, learn about what the function of each clause of the code is included and phrased the way it is. These were usually designed to make explicit the fact that a community wants to be a safe space where underprivileged people can feel comfortable expressing themselves, and it is very easy to make people afraid to express themselves. Fascists understand these CCs and the concept of “safe spaces” were explicitly designed to exclude them, and often attack these ideas.

Continuing on the topic of Nextcloud, this time I talk about generating TLS certificates with the use of Tailscale. This allows me to have a proper HTTPS connection when accessing Nextcloud with Tailscale. No more browsers complaining that the connection is insecure.

@BoxyBSD was always for BSD based systems only. I focussed to push the whole BSD community and to encourage people to try BSD based systems (such like #FreeBSD. #NetBSD, #OpenBSD, etc.) but I'm not sure if it might provide more value to the whole #opensource community by also supporting #Linux systems (such like #Debian, #Ubuntu, #RockyLinux, #SuSe and more).
I'm not sure if the #BoxyBSD project still provides a value for the community right, now.

Torvalds states the obvious: file systems should be case-sensitive
Apparently, the Bcachefs people are having problems with case-folding, and Linus Torvalds himself is not happy about it. Torvalds holds the only right opinion in this matter, which is that filesystems should obviously be case-sensitive.
Case-insensitive names are horribly wrong, and you shouldn't have d

Can I install it parallel to macOS ? In dual boot or so?
What do I have to be aware of? WIFI, WebCam, …drivers?

🌟 Introducing BSD.cafe 🌟
Excited to present the first building block of the BSD Cafe project! When I registered this domain months ago, I envisioned a themed bar where we can casually chat about *BSD systems, Linux, and Open-Source technology among friends, acquaintances, and patrons. But like any bar, discussions can cover a wide range of topics while respecting everyone.
BSD.cafe will be a hub for various tools and services, powered by *BSD.
The first brick is a new Mastodon instance, a gateway to the Fediverse. Registration is open, and the server will be moderated under clear guidelines promoting good behavior and zero tolerance for hate towards anyone. Inclusivity, respect, and constructive dialogue are the key values of this new instance.
The main server is currently hosted in Finland on a small VM, based on #FreeBSD. Services are divided into VNET jails, connected in a LAN via a local bridge. A VPN system is also present and have been able to move individual jails to different, more powerful, machines.
Multimedia data and cache are hosted on another physical server (FreeBSD, within a jail), with Cloudflare in front. The aim is to cache and geodistribute data, reducing network traffic on the main VPS.
Reverse proxy (frontend), mail server, media server, and the instance itself are reachable via #ipv6.
The instance started empty. No unnecessary content was pre-loaded; I want it to grow organically based on users' interests and following. There won't be any preemptive blocks at this stage. Users are encouraged to promptly report anything they find worth flagging.
Join us at https://mastodon.bsd.cafe to build a constructive and inclusive community—a safe and relaxing space for everyone.
Our wiki, located at https://wiki.bsd.cafe, features essential links and articles related to the BSD world. It provides an overview of the tools, services, rules, uptime, and more information about the BSD Cafe Services.
A Matrix server, a Miniflux RSS Reader, the Wiki itself, and the BlendIT Lemmy instance are all part of the BSD Cafe services, with more to come.

Strong suspicion I could swap out #macOS for #Linux, do better with #Minecraft and most everything else, and not do much worse at macOS-specific stuff like #GarageBand and Messages under #OSXKVM (https://github.com/kholia/OSX-KVM).

Grazer Linuxtage
nun sind es schon zwei Amazon-Fire-TV Geräte, die hier ausgemustert rumliegen.
eines ca. 11 Jahre alt, ein Fire-TV Kasterl der zweiten Generation (glaube ich, noch mit LAN-Buchse), und ein ca. 9 oder 8 Jahre alter TV-Stick.
Ob das noch lohnt, die zu Jailbreaken und ein natives #Android oder anderes #Linux drauf zu packen? #amazon #firetv
Mein Papa (ü 80) nutzt ja jetzt #Linux und ist bisher positiv überrascht, wie leicht die Umstellung war. Jetzt fragte er mich, weshalb das nicht mehr Leute machen. Nunja...das fragen wir uns auch. :D
Würde mich nicht wundern, wenn er jetzt anfängt Leute zu bekehren. In der Familie aber auch in seinen zahlreichen Ehrenämtern.
Ist ja auch ne gute Werbung, wenn ein unverkennbarer nicht digital-native sagt, dass es ihm keinerlei Probleme bereitet hat und er deshalb sein altes Gerät kostengünstig und nachhaltig weiter nutzen kann.
Ich hab sogar den Verdacht, dass die Umstellung auf Linux Mint kleiner war, als es die von Win10 auf 11 gewesen wäre.
Edit: Weil ich jetzt schon mehrfach gefragt wurde: Hier ist eine grafisch hübsch gemachte und einfache Erklärung zu Linux. Was, warum, wie und erste Schritte. Gut zum verschenken. ;) https://shop.digitalcourage.de/digitalcourage-buecher-und-broschueren/kum/kurzmundig-einfach-linux-1071.html

The screencap showcases a VLC video player interface on an Android with a video titled "Two decades of Git: A conversation with creator Linus..." The video is currently at 4:40 out of a total duration of 41:49. The video features a man Linus Torvalds sitting in a chair, wearing a gray long-sleeve shirt with a small logo on the left side, and dark pants. He is seated in front of a large window with a view of greenery outside. There are two glasses of water on a small table to his left. The background includes a wooden wall and a large window, suggesting an indoor setting with natural light. The video player interface includes standard controls such as play, pause, and volume adjustment, along with a progress bar indicating the current playback position.
