You can use the 3040 to build an AllStar node.

I would use point to point wireless links between the buildings. Then connect an access point to the link to provide WiFi to the building. Something like the Omada EAP211 should work well for the link.

Mumble supports text chat and images too. Right click on a channel or user and select send message. There is an insert image button in the message window. I wish they would make it so you could just drag and drop an image though.

Yes, that’s why they don’t care about copyrighted content outside of Russia.

There are USB NFC readers. Someone could add support for that to Klipper.

The biggest issue will be radiation. It degrades modern computer hardware pretty quickly.

Programs running on Wine still have access to all of the files that you do. They won’t be able to mess with system files unless they can find some sort of privilege escalation exploit in Wine though.

Anything that relies on an internet connection that should be unnecessary is a bad idea.

That hasn’t stopped the addresses from changing on any of the devices I’ve tried it on.

Android changes its IPv6 address daily. That makes it kinda hard to host anything on it. SLAAC would be fine too if it was a stable address.

Has anyone figured out how to make android use a static IPv6 address? If I have to run a reverse proxy on a real PC, I may as well just host the website from that PC.

That depends on what you are running on it. The Pi 5 will be one of the most energy efficient options, but it’s limited to USB and PCIe 2.0 x1 with an adapter for storage.

That would be the US military. These are Starshield satellites, not Starlink.

For email, you just pay for a host that will let you use your own domain. It’s usually a lot cheaper than getting a static IP and you can easily switch hosts while keeping your email address.

It’s not really even worth attempting to self host your own outbound email these days. It’s a lot of work getting the big email providers to accept your email and if someone has ever sent spam from your IP address, you are pretty much screwed.

The energy density of sodium-ion batteries keeps improving. They are getting pretty close to LiFePO4. Chinese EV manufacturers have started using them. Not everyone needs a super long range, especially in places where there are lots of charging stations available.

I think the future for EV batteries is going to be sodium-ion for quite a while. They are good enough for most people and the materials to make them are plentiful.

I’ve been using KeePassXC. I use Syncthing to keep the database synchronized between computers.

You can enable file versioning so deleted files will be kept for a set amount of time.

It’s a switch, there shouldn’t be anything to go obsolete.

The only thing they are good at doing is producing loads of RFI and pissing off every ham radio operator in the area.
