Exactly this. I have a couple of small projects that are MIT licensed specifically because I don’t care how people use them or what they use them for. If someone finds it useful then they’re welcome to do whatever they want with it.

This idea that I’m being somehow hoodwinked or taken advantage of because the thing that I explicitly said could be used freely is being used in a way that doesn’t align with the values of some other completely uninvolved third party is beyond absurd.

There are a few options there.

As someone else mentioned if you’re using IPv6 then it doesn’t matter, you’re already routing internally even if you’re using the public DNS name, no extra work required.

All the rest are for IPv4.

If you’re not behind CGNAT some routers/gateways are also smart enough with their routing to recognise when they need to route back to their own external IP and will loop back locally instead of making any hops out to the internet. Again, if this is the case for you then no additional work is required other than perhaps running a traceroute to confirm.

Another option is to add a local DNS entry for the name you’re using to resolve to a local IP address instead of your public address. The complexity (or even possibility) of this is going to vary considerably with your setup. If you’re running your own local DNS e.g. pihole or similar then it’s trivial. This is how mine is set up.

If all your clients are going to be on PCs (or devices you have more than the typical manufacturer allowed modicum of control over) then you can do something kind of like the previous, just with all your local hosts files.

If none of the above are options, then you’ll unfortunately have to fall back on using a local name/address, which means a slightly different client setup for devices you use exclusively in your home versus ones you might use elsewhere.

Traffic for a local Jellyfin server should definitely not be going over the internet. Also any reasonably modern client should be able to direct play most media without transcoding.

As for my own Jellyfin setup, one TV has an Nvidia shield plugged in and is using the standard Android TV client. The other is a Samsung smart TV onto which I have side-loaded the Jellyfin Tizen app.

A temporary one that you’re expected to remove as soon as you’ve created the admin user(s) you need, but yes. It should only be there during initial setup and ideally removed before the server is ever exposed to the internet.

But that’s just more business!

Same setup here, two USB drives dangling from my NUC. One of them is even notably slow for a USB drive. Still not an issue at all for home use. I’d probably need a dozen or more people all watching different things on Jellyfin at the same time before it even approached being a problem.

…and installing Steam is the route you want to use to do that?

If you want to be able to tear down your environment and rebuild it or use something else yourself that’s great. I don’t want that taken away from you.

It absolutely should not be in the chain of possible effects from trying to install a common piece of desktop software with a broad target audience.

Counterpoint: Installing widely used software and following common instructions to do so should not ever put you one confirmation away from destroying your desktop environment, no matter how explicit that confirmation is.

The difference between building your own car and designing your own internal combustion engine.

First edition Pathfinder was very close to 3.5. Many people called it 3.75e.

While some of the D&D bones are still there, Second edition Pathfinder is very much its own thing.

That tracks with my experience as well. Literally every single Seagate drive I’ve owned has died, while I have decade old WDs that are still trucking along with zero errors. I decided a while back that I was never touching Seagate again.
