Oh, that's a separate app, I wasn't aware of that, no. Interesting, thanks! I don't use Telegram anymore though.
Did you respond to the right comment? I mentioned Telegram specifically and I'm fairly certain OsmAnd can't do live location sharing.
The nice thing about Apple's Find My is that it runs in the background but only checks and sends your location when someone is actively looking at your location. Do these do that as well? I've tried Telegram's location sharing before and it drains battery like crazy because it keeps the GPS receiver always on.
Sounds like network namespaces.
Join the Matrix support channel if have any problems getting started! The documentation can be very scattered and NixOS throws a lot of new concepts at you :P
I hope it's an option you can toggle. I like the existing system which is essentially a list view where it reflows when you remove an icon. My desktop icons are set to work like this too.
I wonder how they've implemented this for iPads since there the way the layout behaves (list vs 2D grid) actually makes a difference when you rotate the screen.
You can absolutely copy the key, because the device has to give it up to the application during decryption. Or does the application send the encrypted file to the yubikey for it to decrypt it? In which case, that's a lot better and I'm wrong.
Yubikey is only really useful for authentication with a trusted party, and not decryption. You can technically use store a secret key on it but then its two biggest advantages are gone, namely that you can't copy the key and that it doesn't use the limited storage on the device.
IPv6. Just let the other network through the firewall, use direct connections, no overcomplicated tunnel setup needed.
