More playing around with ActivityPub

I keep researching ActivityPub implementations, and I keep finding things like https://github.com/gazpachoteam/mini-activitypub and https://gitlab.com/acefed/strawberryfields-sinatra/-/blob/master/app.rb that make me think I could probably do what Tom MacWright did with ruby and something like SQLite rather than use typescript and a bunch of external resources.
