Fragnesia: New Linux Privilege Escalation Exploit https://lobste.rs/s/zz251k #linux #security
https://github.com/v12-security/pocs/tree/main/fragnesia

If this message is seen by anyone other than just myself, my snac2 instance (powered by the proverbial and figurative energy of a 68k Macintosh, if you will) has successfully made the not all too far move from Germany to Norway, as I continue to consolidate my self-hosted services and clean up the convoluted, multi-VPS and literal-hosted-from-home mess that I've created into something mildly more palatable.

And if not, well, then this was me shouting into the proverbial big void. Win-win either way?

hey everyone,

you may have guessed reading between the lines, but I lost my job in the recent tech layoffs…

also burnt out and realised I need to go back to working on stuff I care about.

I hope to gather enough small monthly sponsors to at least cover the bills, so I can:

- 🖥️ create beautiful apps for #Linux / #GNOME

- ✏️ provide free #design support to #OpenSource projects

if you like my work, please consider $1/month to make this possible?

thank you. :)

I've started running my own Luanti/Voxelibre server on a Raspberry Pi. I can join the server from my laptop, but after walking around, alas, there are no other players. I'm considering making it publicly accessible, so more players can join.
**Dear @ActuallyAutistic people in North America, would you be interested in joining a casual game of #Minecraft** (but it's #Luanti/#Voxelibre; is very similar, and it's free/#OpenSource, and runs even on low-spec hardware)? Note: the server is in Canada, it's in #NorthAmerica where you'll get low-enough latency.
The server would be themed to be geared to those with an actual diagnosis of #Autism (or you're confident you have it, but it's not formally diagnosed). #AuDHD and #ADHD people are also welcome!!
I promise I won't track you in any way! No ads, no spam, no viruses, no nothing like that.

I've overhauled my Patreon! I'm now focused on making CC0 software for Linux and Windows - free, open source, no strings attached. If you want to support the work, vote on what gets built next, or just follow along, the new tiers are live now. Everything I make will always be free for everyone, but if you believe in what I'm doing, this is the best way to help 🙂

Happy hacking!

It says something about how miserable working with Windows and MS Word is for me that I chose to work around a bug that SHOULD make #LibreOffice under #Linux impossible for my work rather than resort to the functional Windows 11 computer that sits 60 cm to my left.

Specifically, any typing in Korean input while tracking changes in Linux/LibreOffice Writer causes LO to crash, meaning I really can't and shouldn't use it for my current assignment which involves adding tracked changes in Korean. However, it's such a nightmare to use Windows/Word, which is theoretically fine for this work, I chose violence — specifically, to copy-and-paste text into LO with track changes on. Need to add just a single character? Can't type it directly into the document, need to go through the text editor and copy-paste. How could this be happening? Will it ever be fixed? Fuck if I know, I hate everything at this point but it seems I hate Microsoft products a tiny bit more than everything else.

Podman rootless containers and the Copy Fail exploit by @ggpsv https://lobste.rs/s/pdckk8 #linux #security
https://garrido.io/notes/podman-rootless-containers-copy-fail/

This one might be interesting to anyone interested in computer gaming history.

https://dec10.uknet.net

I spent the last couple of weeks finally finishing a project I started for Bletchley Park about 20 years ago. Recreating the original MUD and MIST on a mirror of the original Essex University system that finally closed in 1991.

Roy Trubshaw and Richard Bartle wrote the first online multi-user game (MUD) on Essex University's DECSystem-10 in 1978 and it ran till I closed it in 1991. I diligently backed everything up so I could potentially recover it one day, but as far as I can see, all the DECSystem-10's went to the great scrapyard in the sky, my backups were mostly stolen when my first museum was stolen, and I had huge issues recovering the Essex BCPL compiler to compile what I had left when I finally got a decent TOPS-10 emulator running on a VAX for Bletchley Park.

One good thing about being an unemployable whistleblower is free time, so I finally hunkered down to some 90 hour weeks and built a software replica of the Essex system I think reflects it well. It's running on a KS10 not a KL10 but I had to let some things slip.

I put the latest known versions of MUD and MIST on it, and miraculously found ROCK too.

So, to meander to the point, if you want to see and relive exactly what online multi user gaming was like from 1978 to 1991, you can go to:

https://dec10.uknet.net

Or:

telnet telnet.dec10.uknet.net

(Port 2653 is available for ISPs that block 23)

And then follow the terse instructions from there.

In those days, you were generally faced with a "." prompt and left mostly alone, so for authenticity, I will leave it at that.

I should note that although they were, in their day, wildly popular games with a relatively huge community, this is a museum peice in snapshot-form at the moment. But I will leave them up and running to see what happens and as a useful reference. I wasn't going to, but Richard seemed happy to have MUD running, and former MIST players wanted it back, so...

Pop this a share if you know folks who might be interested.

** Update: New web client that works better.

** Another update - I added a telnet client.

Historically, the telnet connection is much more true to the traditional experience, where you were connecting to a working machine that didn't care about the MUD Guests, so there were no pointers at all. Just rumour and hearsay :)

If any of you Unix/Security people notice I messed up something, please tell me. I left "^], !sh" open on the telnet link for about 2 minutes and nearly had a heart-attack once I spotted it :D

This upcoming Sunday I will be kickstarting LIVE #Linux classroom (URL below) guided by Linux Professional Institute LPIC-1 course 102.

This is a fresh start in 2026 and on top of my existing students line-up I hope to see new faces (in live chat) as well. I am looking forward to this knowledge exchange.

I will not mind if you boost this in search of people who can benefit. I do this entirely gratis, but I also welcome tips and thanks on https://ko-fi.com/darth

There is a subtle, almost sadistic pleasure in what I’m doing right now: I open boxes of brand-new ThinkCentre PCs, unpack them, hook them up to a monitor, keyboard, and network cable. I boot from USB and replace the preinstalled Windows 11 (never even started) with my Debian 13 golden image, using Clonezilla.

As of today, the setup is based on Debian 13, but I’m already working on a variant based on FreeBSD and jails.
