There is something about Ruby that makes me completely incapable of finding anything in a Ruby on Rails code base. Firstly, everything is arranged with according to conventions I don't know. Not my preference, but that I could learn or look up. But then there's also vast amount of stuff that just appears out of nowhere.

For instance, currently I suspect there's a mismatch between the url sent by @[email protected] in a Mention tag on an activitypub activity, and the result of calling short``account``url on a Mastodon account model for a remote account. But... there is no function called short``account``url in the Mastodon code base, it doesn't seem to be one of the standard Rails Router helper methods, it just... gets called in a bunch of places and ✨️magic✨️ occurs.
