You live your delusion of purpose, I live mine of zero fucks given, nobody's appearance matters in the cosmic joke anyway.
Be whatever self you scrape together, I don't care, looks mean shit to me when bad mindsets breed harm.
I'm not mad, I'm not lost, I just don't care about looks but do care about mindset, so be happy and be you.
Btw, afaiac I'd love to swap KDE out for Cosmic. But the window rules (or current absence of it) is preventing me from doing it. Like a Kwin for Cosmic, that would be cool. But what the Cosmic team has achieved so far is really impressive. I wouldn't be surprised if this becomes the default DE for Ubuntu.

Am I reading "Being and Nothingness" by Jean-Paul Sartre?
Yes. Because everyone dies. You, me, everyone, and everything we ever cared about. So why should you lose sleep over what happens or what anyone thinks, when the ending is already written?
When nothing has inherent meaning, I might as well understand why.

Protip: if you decide to fuck around with COSMIC on openSUSE, it will swap out kwallet for gnome-keychain, and you'll thereafter get moaning on Plasma session start about your login keyring not being unlocked. Nuke COSMIC gnome-keychain and reinstall the kwallet PAM stack to get things back to normal.

I tried the Fedora Atomic Cosmic Desktop iso and it was very impressive. Cosmic is the most responsive UI I’ve used that isn’t called Workbench. Sadly, Steam had some issues with controllers and while it seemed solvable, it didn’t seem like a clean solution. I’m going to miss Cosmic and will definitely check it out again once it is really done because it is super cool. Now, Bazzite is installing away.
"Astronomers have made a truly mind-boggling discovery using the James Webb Space Telescope (JWST): a runaway black hole 10 million times larger than the sun, rocketing through space at a staggering 2.2 million miles per hour (1,000 kilometers per second).
That not only makes this the first confirmed runaway supermassive black hole, but this object is also one of the fastest-moving bodies ever detected..."
I just upgraded to #popos #cosmic beta, and it mostly just worked! It's also the first DE I've used in a long time that felt like a big step forward - when they get the remaining bugs ironed out I think it'll be great!

Geometric Interpretation of the Redshift Evolution of H_0(z)
Seokcheon Lee
https://arxiv.org/abs/2511.07454 https://arxiv.org/pdf/2511.07454 https://arxiv.org/html/2511.07454
arXiv:2511.07454v1 Announce Type: new
Abstract: Recent analyses of the Master Type Ia supernova (SN Ia) sample have revealed a mild redshift dependence in the inferred local Hubble parameter, often expressed as tilde{H}_0(z) = H_0 (1 z)^{-\alpha}, where \alpha quantifies possible departures from the standard cosmological time dilation relation. In this work, we show that such an empirical scaling can be interpreted as a purely geometric effect arising from a small, gauge-dependent normalization of cosmic time within the Robertson-Walker metric. This interpretation naturally unifies the observed redshift evolution of tilde{H}_0(z) and the corresponding deviation in SN Ia light-curve durations under a single geometric time-normalization framework. We demonstrate that this mapping leaves all background distances--linked to the Hubble radius in the general-relativistic frame--unchanged, while the apparent evolution in SN Ia luminosity distances arises from the redshift dependence of the Chandrasekhar mass. The result provides a unified and observationally consistent explanation of the mild Hubble-tension trend as a manifestation of the geometric structure of cosmic time rather than a modification of the expansion dynamics.

Universe is another word for Cosmos, hence Universix as the name for the bootc Cosmic image I've cooked today. And it worked out very well. More on that tomorrow. Back home an updated MangoWC on Slackware waited for me! Great diversions from a shiite day at the races.

That was a pretty uneventful affair, which is good. The Cosmic liveslak I tried worked well, a much better experience than before. Furthermore very much up to date, the first patch to version 1 already included. Had only to install grub (included, but not activated) and uninstall some standard liveslak packages. But that goes with every Slackware install, so no biggie. Cosmic-greeter behaves a bit quirky also, but that goes for all Cosmic installs. Next week: tweaking.

That FreeBSD Mango setup is coming along nicely. But now I got myself in trouble... Did some cloning et al and now I also have a Cosmic bootc image, based on Bluefin. Took me less than an hour and it's pretty close. So, I'll be at work tomorrow, but you can find me in my git repo 😜

5. Slackware Flatbrew, a KDE QT6 experimental iso, with Brew and Flatpaks (thnx @… 😉)
All working superbly.

The serenity that sets in when you have Slackware Tilers (with Mangowc and Sway), Gentoo with KDE and VoidLinux with dwm configured. And all running equally good and reliable
That's the triumvirate for 2026.
Then we have Slackware Cosmic to test drive for at least a month.
And that Thinkpad for all intermediate urges, like AerynOS, Chimera or Bluefin.
Done and dusted.
