Recently I got asked about my @BoxyBSD@bsd.cafe project, which offers free VPS instances of vary #BSD based systems for learning and educational purposes and I'm happy to share that this projects remains available. Several things could finally be clarified to continue this service to make sure people can learn and practice on real #FreeBSD, #OpenBSD, #NetBSD systems to #RUNBSD. Also, BoxyBSD starts moving over to #Sylve on #bhyve.

But not only that! We could also get some more new resources and locations to scale and this also brings up another new project for #free Linux #VPS instances at https://boxedtux.com (Fedi: @BoxedTux@mastodon.social) where people will be able to learn and practice on different #Linux based distributions (e.g., #Debian, #Ubuntu, #Rocky,...). BoxedTux utilizes #Proxmox clusters as a foundation.

Hope you like this small update... Over & out!

I spent the last couple of days examining the source code and understanding the Copy.Fail vulnerability in detail. This vulnerability happens on the shoulders of 4 key components:

- Page cache
- AF_ALG
- algif_aead
- splice()

In this video, I talk about these components and demonstrate how the CVE-2026-31431 vulnerability allows attackers to gain root access by modifying the “su” entry in the page cache.

systemd-boot: wtf is this dreck?

It works, but like lilo back in the '90s. Actually, that's probably not fair to lilo.

Now I understand why most distros configure it to not display and make you press/hold space to access the menu at boot time. The less we see it the better.

How to Install OpenBSD (2027 Edition)

#OpenBSD #Linux #Install #MemeVideo

Just about every consumer facing operating system, search engine and service is using AI now to some extent. I’ve seen folks switching to #openbsd from Linux/Mac/Windows…but what about other services? Proton has AI, and damn near every internet search engine has AI, even the ones that claim to be private and secure. I’d be interested in hearing some realistic tech stacks and workflows that don’t involve tools with AI in them or created with the help of AI. If you are willing to share please comment.

👩‍💻​ My So Called Sudo Life - day 500: still a newbie edition 🆕​

Dear Fedi friends,

Today marks the 500th day of my self-hosting adventures and I'm celebrating it with... a slice of humble pie:

🔗​: https://blog.elenarossini.com/my-so-called-sudo-life/my-so-called-sudo-life-day-500-still-a-newbie-edition/

Also: please remember to update your Linux system to patch the critical vulnerability that has been found.

#Linux #CopyPaste #security #MySoCalledSudoLife #SelfHosting #YunoHost

Oh, and @zeitkapsl have a #Linux desktop app and one for the command line!

(The desktop app only works as flatpak for me, the RPM has conflicts on my Fedora install).

(EDIT: Problem solved! With this reply https://techhub.social/@konform/116490565176455678)

Librewolf keeps opening the tabs that were opened last, even though I have this tickbox unchecked. I want a fresh session all the time. I never want it to restore anything ever - even if it crashed.

I was able to get this behaviour in my last setup, but I forgot what I did (recently I wiped my hard drive and did a fresh linux install).

Does anyone know how to get this behaviour?

#TIL You can copy or rename files without retyping the path:

❯ cp /your/long/path/config.toml{,.bak}

This expands to:

cp /your/long/path/config.toml /your/long/path/config.bak

Works also with `echo` (nice for testing).

Thanks to @irom for recently pointing me in this direction. 👍️

So you read about #CopyFail, and are like… owww, shit. But then you see that it was responsibly disclosed after being fixed in main, we had releases since, they went stable in #Gentoo (over other #security fixes), so we should be good, right?

Except that it turns out that after it has been fixed in mainline, nobody bothered actually backporting the fix to all the LTS branches. And it doesn't apply cleanly (https://social.treehouse.systems/@thesamesam/116490971618284574). What a shitshow!

(And we've been only talking how 5.x don't get vulnerability fixes in time — but it turns out that anything but the latest is insecure to use!)

#Gentoo #Linux

#KDE #Linux #KDEConnect #computers #software

The exploit includes cpu-specific shell code (ELF). I have the toolchain working to build working shell code and the exploit binary on both Linux/86 and Linux/ARM, but the exploit doesn't work out of the box on ARM.

Anyone got further details if this vulnerability is only valid for x86?

#arm #copyfail #linux #exploit #x86

Holy. Fucking. Fuckballs.

This exploit is... insane.

Right, question for Linux users - I'm getting some surprise money and I'm thinking I'll invest in a colour printer so that I can make my own art prints at home.

I had an Epson Eco-Tank in South Africa but was having a hell of a time calibrating the colours.

Suggestions for printers that work well on Linux (I know Brother are good), that are good for colour art prints?

BLUG, Bergen 2026-05-28: Social anarchic, mad, and misbehaving agents collaboratively solving tasks v/Bjarte Johansen

#bergen #linux #agents #development #programming

@projectanchorage I would look at multiple options.
- If you're strictly stuck with i386 (not even i486) that means #NetBSD is propably the only choice.
- Depending on your goals, you may want to consider #OpenBSD or #386BSD (today's #FreeBSD).
- Not shure if #OpenSolaris / #illumos supported anything beyond #SPARC(v9 / SPARC64) & #amd64.

The question to me is whether or not old #BSD versions emcan even be built with midern toolchains and if choosing them isn't going to bite one in the ass down the line.
- The reason I choose #Linux for @OS1337 is because it's mature toolchain, drivers and hardware support.
- Tho you may rightfully argue that #OS1337 is just taking the #toybox / #musl + linux "distro" #mkroot and basically tries to make something out of it.
