I really enjoy when it when someone injects a dose of "wacky" into something that is taken more or less for granted (Raft) to challenge the standard way of thinking about it.

This article flipped my understanding of split-brain or network partitions on its head: You don't actually have to have a majority to ensure progress, you just have to design your quorum selection criteria in such a way that no other partition believes they are authoritative, and these finite projection planes are an interesting way of proving that (with caveats).
