gollark: https://github.com/awesome-selfhosted/awesome-selfhosted#photo-and-video-galleries has some things which apparently have AIish features.
gollark: I've never used it so it might be bad.
gollark: You *can* do that locally. There's software for it.
gollark: I vaguely remember reading that people just got rid of drives with bad sectors, since usually they would soon develop more bad sectors.
gollark: Why do you *have* 11 copies of the same data on disks in the same place, anyway? Weird way to do backups.
