wait, so if you federate with another instance through one community, you won't get to see the rest of the feeds from that instance?

would subscribing to the domain directly (like kbin allows, maybe lemmy could in the future) reduce the number of actions to 700^2?

This would increase server load and traffic by a huge amount though, and would the benefit really be that big?

There are already quite good places to find communities for stuff you're interested in, and less niche stuff will be federated "automatically" by these rules unless you're on a small instance.

Good community lists:

Sorry! My bad, numbers are incorrrect but I'm not sure how to calculate correct numbers lol. Wouldn't it be 700x699 or 699x699 because instance wouldn't have to federate with itself?

oh yeah, it is n * (n - 1)

bc ~700 bots need to do ~700 minus 1 actions

a continue inside an if statement checking if the bot domain is the same as the subscribing one would suffice


edit: or use a search algorithm to pop the domain from the stack before starting the loop, that would be more efficient

edit2: even better: assuming all bot names are the same, you just iterate over the stack (constant), and pop each domain (new stack minus popped domain) and feed it to the 2nd loop.

edit3: SCRATCH EVERYTHING. The bot names don't even have to be the same, you just iterate over a constant stack of botname@domain entries and pop the iteration from it... feed the new stack to the second loop (nested) and done. Why did I take so long to reach this?
