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)?
How is it over there and is there much lag in getting messages from other federated servers?
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?
