I take rsync for granted. It's just the best way to keep stuff out there
up to date with stuff over here, and vice versa. And lately, I've been
using it to supplant my usage of
scp. And it works. Brilliantly. And until
recently, I hadn't stopped to realize: Hey, you know, this thing somehow works
out differences between files out there and over here long before
what's here gets there. I know, duh, but I just hadn't considered it.
Well, Paul Holbrook reminded me of this tonight, with links to Andrew Tridgell's paper on the algorithm, among other things. Damn, things like this remind me that I'm supposed to be getting my butt back into school...
