No, the browser would still send YouTube.com as the host header. While yewtu.be could be configured to allow this to work, the TLS cert would not and the browser would get upset.
Also the alternator absolutely takes more power from the engine in proportion to how much energy it's putting out.
Jellyfin is very conveniently packaged in docker, so while it may seem daunting, I highly recommend at least trying that route.
Running an nfs mount, docker or not, should be perfectly fine. Jellyfin just uses normal storage so won't care if it's nfs. No real special considerations with proxmox either, especially without worrying about a dedicated GPU. Just spin up a Debian guest and go.
Fortunately that's not how it works when you have all the access points controlled centrally, like with unifi. Yes there is limited frequency space, but this is much less of an issue on 5ghz. There will also only be one ssid, and handoff between access points is pretty seamless.
3-4 is probably overkill, but the attenuation situation sounded pretty dire. I run two in my house for redundancy mostly, just standard American stud and drywall construction.
If you have the ability to easily add wires, I would go with a system that allows you to wire everything together, rather than depending on a purely wifi mesh. Personally I'm running unifi ceiling mounted access points for this. They run on power over Ethernet, so you just need to get one cable to each. You can control them with their free software controller if you are into that, or something like their dream router.
Run 3-4 of those access points placed throughout the house and you'll never have a weak signal again.
Why does this only work in Hondas? What about this cares about the car?
Sand, sand, and sand some more. When you think you are done sanding, sand some more.
I ran zoneminder for years, and while it worked, I never much liked how much of a pain it was to set up. I've since moved to frigate, which is better suited to run in docker. If you know how to connect to the cameras with VLC, that should be the same info you need to configure frigate. If you have a 6th gen or newer (iirc) Intel cpu with a built in GPU, that will run the object detection portion of frigate just fine in my experience as well.
One downside in frigate i miss from zoneminder/zmninja is having all cameras live streaming from the main feed, frigate just gives you a snapshot in that view. They do have the Birdseye view that shows all motion in real time though.
I used the paper plans from Chesapeake light craft, and was able to source most of the supplies locally. It's built from marine grade plywood, 4 mil thick, traced off the paper plans and cut out with a jig saw. It's then "stitched" together with copper wire and "glued" together with epoxy resin and the whole thing covered in fiberglass. That's an over simplification of the process, but it's really not too bad, just time consuming. Took me close to 6 months of nights and weekends off and on, probably about $800 all in.
Kayak is a clc shearwater sport that I built in my basement.
If a controller is still connected (Bluetooth?) it may be a controller order issue, you can try reordering them.
