Just remember that you will be required to remove any illegal content that people post. I certainly wouldn’t want to be responsible for that.

That’s what DNS is for.

You would have to specifically open a port in your firewall before anyone could access a device over IPv6 on your network from the internet. Just like you would have to forward a port on IPv4.

Enable file versioning in Syncthing. Then you will have a backup copy of every change for however long you set it to keep them.

HTTP works fine in Firefox unless you set it to HTTPS only. Even then, you only have to click off a warning to open an HTTP site.

Put a multi port NIC in your router PC and use a separate unmanaged switch for each network then.

I would just get a basic layer 2 managed switch and use VLANs. The 5 port and 8 port switches are super cheap these days.

It gets rid of most of the login attempts for me. I don’t use a popular port though. Pick a 5 digit port so they have to put in some effort to find it.

The SSH and VPN traffic is encrypted. Unless your private keys have been compromised, nobody can see what is going over the tunnel. They can log things like the IP addresses that are connecting to it and how much data is being transferred though.

Or self driving cars.

There’s always the option of using computer monitors or projectors.

Yeah, I definitely wouldn’t recommend putting something power hungry like a GPU in one of these. A NIC will be fine though.

They are not USB based, they just happen to use a USB 3 cable to carry the PCIe signals.

If you don’t want to risk modifying the slot, try one of the cheap PCIe risers on amazon and send it back if it doesn’t work. You will need a case with a couple of extra slots under the motherboard in order to fit the riser in there though.

It will run slower, but that probably won’t be an issue unless you plan to max out all 4 ports simultaneously.

Yes, a used PC can work great for a home server. Just don’t go too old or it will be power hungry. Obviously you will want one with an integrated GPU to save power too. If you want to run jellyfin, make sure it supports hardware video encoding, preferably AV1 or H.265.

Any Japanese made surround sound receiver and speakers than you can pick up from a thrift store or craigslist will sound way better than the modern junk. It will have a big, heavy power transformer and linear amplifiers. There will be no internet connected spyware either. If you find one from the 90’s, it will likely have a phono preamp for your record player too.

OCR makes a lot of mistakes, so unless someone bothered to go through and correct them, it’s only really useful for searching for keywords.

Zonemider is accessed through a web interface. Just enable HTTPS and put a lets encrypt certificate on the web server. Of course if you don’t have a publicly accessible IP address, things get more complicated since you will need a VPN or some sort of tunnel.

You could install ZoneMinder and set it up with your webcam. It will do recording and basic motion detection. You don’t have to mess with any docker stuff, it just needs a recent version of Debian or Ubuntu. If you want to access it from a phone, I would suggest using the zmNinja app since the web UI sucks on mobile.

Some actual CCTV IP cameras would be better than a webcam if you can still find any that provide an RTSP stream and don’t require any of that cloud crap.

I didn’t even know it was still around. I stopped using it when microsoft bought it.
