Not much else needs to be said tbh. Fuck Spez. // Edit: Not sure why imgur marked the album as NSFW, but there’s nothing NSFW in it other than the name of one of the mods including the word “removed”
Personal comment: the critter isn’t even dead but the vultures are already flying in circles around it. I certainly do not envy their situation, I bet that the users will treat them like shit.
That doesn’t work with posts or comments, as each instance assigns a different number.
I wonder how much work it would be to make that a hash and make it so that it’s the same across instances
I could see a system being both easy, and hard to implement; Without thinking about it too much, it’d require a hash table filled with every single already-used key that is always perfectly synced with every other instance regardless of each instance’s chosen federated instances.
Best bet might be to just have a non-linear, randomly chosen, hash with a fixed key-length backed by a very large keyspace. This could effectively defeat the need for perfect syncing due to a greatly decreased chance of collision over short periods of time (statistically covering any minute-or-two long desyncs).
They could just go with UUIDs. Assuming all servers choose actually random UUIDs, the probability of a collision is astronomically low. Even if a server tries to maliciously “claim” UUIDs, that server could be defederated from, and the number of UUIDs it’d be able to eat is similarly tiny in comparison.
Yeah, I mean the goal would be to link the IDs across all instances. Rather than having different numbers and running a calculation into a table that links the IDs, you could just have a table, or better yet just have the same ID.
The issue probably lies in creation of new IDs. Different instances may have to be allocated a block of IDs, so that they can create new IDs without conflicting with any other instance.
If youvwant that you’d be using public key cryptography and having the user hold a private key
