Yeah, I’ve written some custom css to get some better wrapping of libraries and such.
There’s also the community themes worth looking into.

The space inefficiency is definitely there.
I find that clients, such as Jellyfin, Moonlight and Signal, works just fine as flatpaks but with those three apps my /var/lib/flatpak/ lands on 6.4GB.
When I temporarily had Discord installed it grew to 6.7GB, so the inefficiency is frontloaded and lessens the more of them you use.

Just played a bunch of episodes on Fedora KDE (Flatpak from flathub, Jellyfin client v.1.11.1, Jellyfin server v.10.10.6) without any trouble.

I would go for a reverse proxy to get ssl running.

Handling users with forgotten passwords is, sadly, a manual chore for the administrator.

Ah, if you’re allergic to flatpaks and can’t convince your distribution to include it in their repository then you can always build it yourself - https://github.com/jellyfin/jellyfin-media-player
Or just use their web based client with a browser of your choice. :)

As I was curious, Findroid gives you an android client that allows offline mode and downloading/playing/removing movies from the client.
Seems Infuse Pro (paid) version also has support for it if you’re an iPhone user.
edit: I see the discussion regarding filesizes and I believe that Findroid is downloading the raw file in the background, so for those that wish for smaller transcoded versions in the cache it isn’t a solution. I don’t own any apple devices so can’t tell how Infuse handles it.

The default Jellyfin client isn’t great for audiobooks.
For Apple iOS you might wanna look at https://github.com/LeoKlaus/plappa
For Android I would look at https://github.com/advplyr/audiobookshelf
Personally I just download the audiobooks from Jellyfin and play it in https://f-droid.org/packages/com.prangesoftwaresolutions.audioanchor/

They too put a whole lot behind their subscription though

I mean, except for Tizen OS isn’t most available? You can find the client for Android, Android TV, Windows, Linux (Flatpak), macos, apple ios, and more.

I didn’t enjoy using Jellyfin for audiobooks, on my android I use the Jellyfin client to download the book I wanna listen to and then I use AudioAnchor for listening to it.

I haven’t used Plex myself but Jellyfin doesn’t create any kind of meta files in the library folders. If that is true for Plex as well then I don’t see why it would be a problem to point them at the same shared library.

As a result I imagine more users will look at other offerings such as Jellyfin.

Router: opnsense/pfsense
Switch: I guess look at something like Open vSwitch After some more reading I would go for a proprietary managed switch here. WiFi/Mesh network: OpenWrt with 802.11r setup - https://openwrt.org/docs/guide-user/network/wifi/roaming
Server: Proxmox or Debian Bookworm with KVM/Qemu
Docker/Kubernetes: Portainer CE version as a VM in Proxmox - https://github.com/portainer/portainer
Collab software: https://github.com/nextcloud/server
Server Backup: Proxmox backup server or Borg backup/Restic
Client backup: Borg backup/Restic

Most of my data are on 2x16TB HDDs running an mdraid1 and then I backup it all to a usb drive with Borg Backup.
The os.qcow2 files live on my m.2 NVMe and are manually backuped to the mdraid1 before running the borg backup.
I should automate the borg backup but currently I just do it manually a few times a month.
Would also like to have two usb drives and keep one offline in another part of the house but that’s another future project.

Open them up with a screwdriver and then either smash the disks inside or continue dissassembling it for fun before destroying the disks.

Interesting, gonna check out the selfhosted bookwyrm later.
I’m not much interested in sharing book reviews and the like so I will probably stick to https://calibre-ebook.com/ though.

I went for a tiny Ryzen 7600 (no X), so it comes at the cost of a worse cpu and worse gpu. :)

My server has a gaming vm with gpu passthrough (6650 XT). With my vm powered on and idle the whole server draws about 60w-65w. Monitor not included.

That’s true, if there’s no load then the difference isn’t much money.
I’m running a NAS, some game servers, a forgejo instance and a jellyfin server and more on my machine so it’s never truly idle and I forgot to think about that metric.

Ah right, that rings a bell. Proxmox and Ceph sounds like a perfect experiment for OPs hardware. :)
