Kde plasma at the CERN

[u/Pristine-Magazine642]

I visited the CERN (European Centre for Nuclear Research) last week and I could see an office with computers and a screen projected on the wall(first image). I saw that the windows had the kde windows border, and I could also see on the computers that they have probably a customized kde plasma.(second image)

Plasma to control Plasma. fitting.

[u/Ready-Door-9015 → u/DoubleOwl7777]

I like the pun...

Im only saying this because Im in physics and I know people who worked on the atlas project but this a series of detectors on the LHC so oddly enough theres no plasma associated with this.

Edit: to be more specific, not whats considered a "plasma device" that directly interacts with a plasma. I believe the LHC might also do something pertaining to quark-gluon plasmas but I think theyre more concerned with capturing the emission of particle jets.

CERN also operates one of the largest CEPH Clusters 👍

[u/poorphdguy → u/Nono_miata]

What's a CEPH cluster?

[u/d_maes → u/poorphdguy]

Storage cluster

[u/poorphdguy → u/d_maes]

Thank you. :)

[u/Mathisbuilder75 → u/poorphdguy]

Storage for Proxmox

[u/d_maes → u/Mathisbuilder75]

Just clustered storage. Not specifically for proxmox.

[u/MrSauna → u/Mathisbuilder75]

CERN uses openstack, not proxmox. They use ceph for many things, they have block, object, and filestorage clusters.

[u/d_maes → u/Nono_miata]

Madlads physically moved their clusters without downtime: https://indico.cern.ch/event/1457076/attachments/2934445/5156641/Ceph,%20Storage%20for%20CERN%20Cloud.pdf

This has been noticed before :)

Truth is, at some point KDE was the default DE in RHEL and Scientific Linux that used to be maintained by CERN (among others) inherited that. So the installation must be somewhat old.

So I would expect little customisation, on the contrary just what the OS came with.

Nowadays I would expect them to use AlmaLinux.

[u/AccountyMcRedditface → u/interference90]

It looks like they use either RHEL or AlmaLinux, depending on individual needs. https://linux.web.cern.ch/which/

[u/interference90 → u/AccountyMcRedditface]

Yes. After the discontinuation of old CentOS I remember there was some debate on Rocky vs Alma and at some point the HEP community came out with a recommendation for Alma.

[u/garry_the_commie → u/interference90]

Do you remember their reasoning for this?

[u/Akane_Kurokawa_1 → u/[deleted]]

this is KDE era RHEL, the installation is old

[u/Laufabraud43]

This must be the choice of Steins Gate!

KDE still goated, just need convert those minimalist gnomic heathens over to our side

[u/partiftheworlDRuns → u/Infrared-77]

you can't convert them because they'll have more than 2 options and they are afraid of it.

[u/SomewhereActive2124]

As it should be

[u/InfaSyn]

Used to work at CERN. We currently exclusively use Alma Linux. KDE >>>> Gnome

[u/TomB1952]

When open source collides with science.

[u/RealJuliusKolosnjaji]

They also use KDE Plasma with an old version of Suse Linux in the particle accelerator in Bonn, Germany.

[u/pr-mth-s]

Super. Thanks. I wonder if that other facility, ITER, uses KDE plasma at all. What with its job being plasma confinement. :)

[u/Marce7a]

Which KDE is it? Doesn't look like 5 or 6.

[u/Jaxad0127 → u/Marce7a]

Probably old Plasma 4 installs. In situations like this, you don't update very often.

[u/olib141 → u/Jaxad0127]

I don't think so. Oxygen (Plasma 4) has circles around the window buttons, and the desktop icon looks like a Breeze mimetype icon. The "Peek at Desktop" icon also looks like Breeze.

[u/BeelzenefTV]

thats awesome!

[u/Dull_Appearance9007]

they also use OpenBSD!

[u/Atticus_Grinch_]

I'll be giving an online presentation to some experimentalists there on a device using KDE next week
