Go with CAT6 and you should be fine if the total length of all 3 cables is less than 100m. CAT5 will work for the TV but CAT6 will work for more uses in the future and shouldn't be too much more expensive unless your electrician has a bunch of CAT5 that they are trying to get rid of.
Edit: Also if you are thinking of wiring more locations the ideal solution is to bring all of the cables to a single location where you can connect to an Ethernet switch.
You may want to try hotter too if you haven't yet. Printing faster can sometimes require a bit of extra heat and too low can cause a different kind of stringing.
The plastic and wire twist ties that come on cables would work too.
The expression syntax for the GNU find command is very powerful. I would expect that it is up to the task. If you don't have the GNU find command with it's extensions I could see how it's would be difficult.
QEMU supports either spice, vnc or sdl graphics output. If you want to copy/paste you need to use spice and install the spice agent on the VM.
If you want an automated system that can protect against ransomware your backups need to be hosted in some way where the backup server has control of the retention and not the client (NAS, local disk, etc are not sufficient). If your NAS supports automated snapshots that can't be deleted by the backup user it can mostly fill this gap but may need to be checked for how it handles snapshots when the disk fills.
For self-hosted solutions I've used BURP, Amanda, and Borg backup in the past but have switched to Proxmox backup server as my VMs all run in Proxmox. You still need to consider full disaster recovery scenarios where both your primary and backup system fail. For this PBS sports both tape and remote server replication.
There are also many cloud solutions that do this automatically. For cloud I would always use them in tandem with some kind of local backup.
For all of these they should have an admin account that has strong protection and doesn't share credentials with any of the primary systems.
My steam deck also unlinks family libraries with almost every os update. It might be an issue of overzealous hardware validation but it could also just be a bug.
It's very likely that your disk is failing.
dd if=/path/to/file.mkv of=/new/file/path.mkv conv=noerror,sync bs=4k
Should give you a file with just the damaged bits missing.
PTSD from the days long ago when X11 error log would fill up the disk when certain applications were used.
The underutilized ~~post~~ pre increment operator.
Are they on a local disk? Thunar doesn't render any thumbnails for remote storage by default.
I've had a system in the late 90s with a 3dfx voodoo card. Also had a laptop with a SIS card from the early 2000 era.
The voodoo card was THE card to have it it's day (mine was an older second hand system though). The SIS card... for some reason they decided that standard VESA mode probing wasn't a thing they supported and would hardware crash when that API was used. I eventually got it working in Linux after patching xfree86 to not attempt probing when loading the VESA driver.
