It's very sad to see #rsync getting polluted with LLM slop now.
Even more sad, given who is doing it.
People are talking angrily about "the maintainer" and suggesting "this guy" [should have his commit bit revoked] etc. apparently not realising that "this guy" is Tridge, both the original author of rsync and creator of samba. His PhD thesis "Efficient Sorting & Synchronization Algorithms" describes the original rsync algorithm. Still worth a read, even now.
