AlmaLinux provides some "Live" images with various desktop environments. I installed the KDE "spin" and found out that there is a crap load of useless / unwanted packages. Here are my notes to disable them.
Packages that I don't need:
$ sudo dnf remove kmines kmahjongg kolourpaint kruler akregator kmail konversation dragon juk kamoso kaddressbook korganizer plasma-discover flatpak* sssd* java-11-openjdk-headless oddjob
You may want to keep sssd and oddjob if your workstation has membership to an Active Directory. You may also want to keep plasma-discover if you want a GUI to search for packages and have software updates notifications.
Softwares that can be a security issue on a workstation (they may listen for connections or allow unwanted remote access):
$ sudo dnf remove cockpit* krfb krdc hyperv* mariadb* open-vm-tools qemu-guest-agent spice-vdagent tcpdump openssh-server
It's a shame that AlmaLinux and RockyLinux do not provide a "minimal" KDE Live image, or a clear documentation to install a minimal set of packages. Let's hope that KDE gets more attention from Red Hat for the next major release!
I've been using NVIDIA Broadcast for years, a magic tool that helps me to record my voice by removing static / white / ambient noise and even nullifying the reverberation in my room. This software requires of course Microsoft Windows AND an NVIDIA card.
The result was quite impressive but I needed an alternative since I don't use Windows any longer neither an NVIDIA card. That's when I found out rnnoise which is a free software compatible with Linux.
Note: I will explaine how use rnnoise to convert a raw or wav file. I don't know how to use it to filter out audio on a live stream. I assume it's possible since rnnoise is a library that can be used as a plugin for obs-studio or pipewire but I just didn't try that part.

Mon profil : bientôt quarantenaire, j'ai commencé le gaming dans les années 90 sous DOS, j'ai connu la transition de la 2D vers la 3D, les LAN party, l'avènement du dématérialisé, la disparition des supports physiques. Je suis un pur gamer solo et le multijoueurs en ligne ne m'intéresse pas du tout. Autant dire qu'en 2024 je fais partie de la minorité de joueurs qui ne rapporte pas d'argent aux éditeurs.

We had that crazy situation where a Zabbix Proxy was down (VM stopped) and we had no idea about it.
That was quite the surprise because "Well, we should have had a crapload of 'No data' alerts from every host that report to that proxy". Spoiler alert: No, we didn't. We lost monitoring over hundreds of hosts for 24+ hours and everything was fine in Zabbix UI. In fact I realized that situation when the network engineer asked me why his Zabbix dashboards were empty.

Petite curiosité, j'ai reçu ce matin un SMS m'informant que "ma carte vitale va expirer" avec un lien totalement bidon. Alors que j'étais en train de le signaler au 33700, j'ai remarqué que mon iphone m'affichait un aperçu du fameux site, qui n'était autre que mediapart.fr. Diantre, pourquoi un SMS d'anarque contiendrait-il un lien vers mediapart ? Quel est le but ?
