alt Hacker News> (Alternatively, I would consider getting rid of numerical ids altogether and relying on name alone. Internet Archive does it at e.g. archive.org/details/leroy-lettering-sets, but that has some serious limitations that are not hard to imagine.)
I could try to imagine these limitations and how the Internet Archive overcomes them, but I'd prefer reading about it.
I'm always surprised that archive.org's URL scheme is still used. To this day uploads will have URLs like `/details/hey` and IIRC the only thing to distinguish them from other submissions with matching names is the auto appending of a digit. It feels like `New Folder (1)` for URLs.
Edit: I misremembered. They append the date to the URL to avoid name conflicts, like `/details/hey_20260122`.
I think Youtube got it right early. Make it short enough but random, so users won't be tempted to manually type it out and make mistakes but if they really do need to manually type it the length is reasonable. It also made sharing via SMS/Twitter limits more feasible.
