Going deep on UUIDs and ULIDs
Not too long ago the Honeybadger team was debating between ULID vs UUID choice for primary keys. Ben, our dev-ops master, mentioned that he wished he'd used ULIDs instead of UUIDs for a particular system we built. Like any seasoned engineer in software development, my initial reaction was to mumble something non-committal and then sneak over to Google to try to figure out what the hell a ULID is. UUIDs are a bit more common, but I hadn't even heard of ULIDs.
