  • Mini PC for Jellyfin

    Jump

  • No, they're almost entirely unrelated. Almost all CPUs will idle close to 0 W (with correctly working drivers). The main idle power contribution comes from the mainboard and other devices (e.g. disks). The Mini PCs you mentioned should have a very low total idle power, probably below 10W.

    Check out Wolfgang on YouTube, he has some great videos on the topic: https://youtu.be/Ppo6C_JhDHM

  • Switching from a Media Drive to my first self-build NAS

    Jump

  • I've also recently built my own NAS and I've gone through similar considerations. One of my mayor decisions was not to use btrfs because it's not recommended for Raid Z1/Raid 5. With that, I landed on ZFS and TrueNAS Scale. Note that RAID expansion should be landing in both very soon.

    Things with TrueNAS were pretty easy, very quick, and everything worked nicely. However, I noticed that it was constantly accessing the disks and preventing them from spinning down. I really wanted to keep the power consumption low (<20 W idle), so I eventually decided to just go with Vanilla Debian + ZFS. I can recommend that if you want to tinker with things yourself. Otherwise, I'd recommend TrueNAS Scale.

    As for migration, you might be able to create a degraded pool initially, copy over the data, and add the parity disk last. Raid expansion would ofc also help there...

  • See-Through Windows Make Clean Electricity From Raindrops

    Jump

  • What kind of junk energy is there to harvest from a car (in meaningful amounts)? I guess breaking is the obvious answer, but that's already covered by regenerative breaking. Most car-based energy harvesting systems seem to employ speedbumps that clearly take useful (kinetic) energy away from the car (probably at a very poor efficiency).

  • See-Through Windows Make Clean Electricity From Raindrops

    Jump

  • How would a turbine that takes energy from the air current generated by a passing car decrease the energy of the car?

    Not sure where you got that idea from, but how would that generate a meaningful amount of energy? It seems very unlikely that such a system would ever recover the energy spent on its construction.

  • See-Through Windows Make Clean Electricity From Raindrops

    Jump

  • Sure, but those are completely different approaches. Dams have the advantage that they have a much larger capture area for water and that they can accelerate the water beyond the 10 m/s terminal velocity of raindrops.

  • Did you perform a full shutdown of Windows (Windows doesn't fully release the partition on a normal shutdown)?

  • RPM to APT distros correspondence

    Jump

  • Edit: adding some context. I am planning to setup a dev machine that I will connect to remotely and would like to babysit very little while having stable and fresh packages. In the Ubuntu world we would go to an LTS release but on the RPM/Dnf world is there any other distro apart from CentOS Stream? And also is CentOS Stream comparable to an LTS release at all considering that they do not have release number?

    Wanting both stable and fresh packages is unfortunately somewhat difficult in my experience. I think the primary choice within the Fedora ecosystem is if you want to have fresh packages (Fedora) or if you prefer a slower update cycle and more stable packages (RHEL/Alma/Rocky). In the second case you can also choose if you wish to pay Red Hat for support (RHEL) or not (Alma or Rocky).

    One thing that's quite different in RHEL vs Ubuntu/Debian ist that it gets minor releases that include substantial new features. For example you'll get new compilers, python versions, drivers, ... CentOS Stream gets those slightly ahead of RHEL/Alma/Rocky (a cynical person might say that CentOS Stream is a rolling beta for RHEL). But, IMHO that's not really a strong reason to use CentOS Stream.

    If you'd go with an Ubuntu LTS release, then I'd look into RHEL/Alma/Rocky.

  • Installing CH340 drivers in Linux Mint running 5.15.0-88 kernel

  • How to exclude flatpaks from TimeShift?

    Jump

  • You can make this work using ext and Timeshift rsync. I have also opted to exclude /var/lib/flatpak/ because it's quite large. With that, my 5 snapshots currently take up about 34 GB.

    However, I would recommend backing up your deb applications/packages (typically installed under/usr), as those can be critical for your system.

  • New Open Source law in Switzerland

    Jump

  • This "new law" was passed more than a year ago... But, it's still a step in the right direction.

  • Good luck :)

  • It says "UNSUPPORTED: VSYNC is not available on the Linux platform." and runs at a stuttery 133 fps. This test shows 144 Hz: https://fpstest.org/refresh-rate-test/ The Nvidia settings app shows 144 Hz + VRR are active and I can see that the cursor is rendered at >70 fps.

  • fixed with cinnamon gum.

    Jump

  • I'm pretty sure that my desktop is drawn at 144 Hz (on the primary display) and xrandr also tells me that that's the active mode. 🤷‍♂️

    Edit: This is with Nvidia (proprietary drivers) and VRR monitors.

  • fixed with cinnamon gum.

    Jump

  • Is that generally an issue on Linux Mint / Cinnamon X11? I have a 144 Hz and a 70 Hz monitor and they seem to work fine....

  • Generate document from templates and database

    Jump

  • One way to do it is have a small Python (or any other scripting language really) script that performs text replacements in the Latex source file. This is much easier in Latex because it's plain text. I don't know of a solution that doesn't involve writing your own code (apart from LO/Word serial letters).

  • Generate document from templates and database

    Jump

  • Is using Latex an option? I've done that and it works quite nicely. You can easily populate a template e.g. using Python.

  • Don't dare to question Gnome

    Jump

  • I'm not sure I follow... Did the Fedora Council actually take a decision?

  • Don't dare to question Gnome

    Jump

  • I understood Matthew's position as "this should be discussed in the Workstation WG first", not as a "no":

    in favor of the process outlined above (tl;dr: talk to the Workstation WG, and if that does not come to a satisfying outcome, file a Council ticket for next possibilities).

    Post

    It also seemed more likely that they would promote KDE without demoting Gnome.

    But was there a follow-up on that (e.g. in the Workstation WG)?
