random n00by question: say that i have a key card and already determined that it's not NFC. what's the easiest way to figure out what protocol it is using? assuming it is passive RFID, is there a DIY way to read it (like with an SDR)?
Mastodon's federation introduces UX challenges.
One that worries me a lot is about message forgery. Anyone can forge a twoot, even cross-server.
Whereas Twitter Inc might be trustworthy enough to not forge transcripts. Anyone can run a Mastodon server and might want to abuse it to influence people (see Russian troll campaigns).
Should Mastodon "home servers" cryptographically sign updates? Should there be end-to-end signatures? Anyone has thoughts on this?
