It’s honestly the same as with Windows - search engines and manuals.
When you get stuck explain what you want to do, what you’ve tried and what guides/manuals you’ve used and you’ll get good responses from most of the linux communities.

I know both ASRock and MSI released bios updates for AM4 boards, ASUS didn’t. All three released updates for AM5 with the new 2023 CA certs.

Nah, but there should be a BIOS/UEFI firmware update available and those are always nice to keep up with.
If Secure Boot is the security guard at the entrance then updating the BIOS/UEFI gives him the latest rulebook and will make the process simpler if you decide you want Secure Boot in the future.
The update can also have other fixes that you want.

Only thing I can think of is to remove your default account from the sudoers file and have an account with a frustratingly long password written on physical paper hold the keys to the kingdom. That will make a whole lot of other things a hurdle too though.

You can think of Secure Boot as a security guard at an entrance. The security guard checks the ID badge of the software that wants in to verify it’s signed by a trusted company.
All ID badges are now being updated, the old seal of trust from 2011 will no longer be accepted and they must use the new seal from 2023.
The Security Guard will enforce this 2026-06-17.

An easy first step is to check BIOS and see if you can simply increase your fan speeds there for an immediate gain.
Another easy quick fix is to add a normal desktop fan placed so it pushes air towards your intake fans.
Third cheap way is to check what fans your case has today and what fits in it. Even the cheap 120mm fans from Arctic or Thermalright can increase airflow and lower temperatures.

Eaton works well with https://wiki.debian.org/nut and I think the 5SC1000 fits your power needs.

Must it be an APC or does any brand of UPS work?

You could try installing the flatpak version of Loupe and set it as your default program for .heic. Should solve it for you on Fedora Silverblue.

I would probably split into the new one being your prod machine that runs everything important and use the old one for experimenting and labbing.

“So just to make it really clear: If you found a bug using AI tools, the chances are somebody else found it too. If you actually want to add value, read the documentation, create a patch too, and add some real value on top of what the AI did. Don’t be the drive-by ‘send a random report with no real understanding’ kind of person. OK?”

Makes sense to me, most of the time the AI output need to be used as input for a human who can then deliver the real value, or at least verify the correctness of the AI output.

I only have a vague understanding of btrfs and its subvolume structure.
It sounds to me like Snapper + Borg / BorgUI would give you better btrfs snapshots with the built in grub menu entries and better backups than Timeshift alone.

As someone with more of a legacy workflow where I simply put backups of my machine on my NAS regularly can you describe what differs between Snapper and Timeshift? Can’t you use Snapper as a replacement?

I’m not really into video guides myself but a quick search landed me on one that seems to be helpful for setting up debian13 with btrfs and timeshift. I can understand your frustration considering how much work it requires.

I’ve only had a quick look at OpenSUSE Tumbleweed but as you say it seems a better fit if you want btrfs and snapshot rollback working straight out of the package.

Found this older thread on the fedora forums
https://discussion.fedoraproject.org/t/hp-printer-stopped-printing/87174/72

If your friend has no other printer then it might be worthwhile to remove the printer if it exists, then remove ipp-usb and hplip, reboot and finally reinstall the hplip packages from dnf again.
sudo dnf remove ipp-usb
sudo dnf remove hplip
reboot
sudo dnf install hplip hplip-gui

Personally I haven’t had the displeasure of touching a hp printer in a long time so my tip is based on the thread not experience.

Welcome to the losing side, I guess. At least an ancient egyptian would enjoy the fact that we’ve regressed to using hieroglyphs instead of proper written words in our menu systems.

“Press the hamburger menu in the upper corner” “the what now?” “Press the three horizontal lines in the upper corner and then look for the cogwheel” compared to “Press “File” in the upper corner and then choose “Settings””.

If making design and aesthetics easier in multiple languages means regressing to hieroglyphs that change meaning depending on context, then I rather have a menu that grows a bit unseemly when using a language with longer words than English.

I think I prefer having to tile my windows with Super+Arrow keys to be honest. I doubt Hyprland will know what I run in the different terminal windows and therefore can’t automagically tile them in the quarters I want them.
But I haven’t tried it, been too satisfied with KDE Plasma to look further at Wayland desktops.

I imagine that they don’t care for the small segment of users that can install another OS. Even if they stay at Windows we probably hamper and sabotage the telemetry/adware parts of the OS and become less profitable.

When looking at their Q4 earnings the Windows and Devices and Advertisement revenue should be high enough to warrant some effort. That effort is probably to increase the Advertisement revenue though.

The stream detector addon often makes it easy to grab the media.

After user outrage Fedora settled on opt-in telemetry instead of opt-out. So unless you actively choose to send telemetry you’re not gonna do it with Fedora.
