A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

[SOLVED] Why is my Lemmy instance not finding other instances' communities? (lemmy.world)

Edit: YOOOOOOOO YOU CAN EDIT TITLES HERE

Anyway, you have to first search for the community in the format [!whatever@where.ever](/c/whatever@where.ever). It doesn't show up the first time but if you mash Enter for a while it will...

Also, this FAQ linked by @Wistful@discuss.technics.de is pretty helpful and covers some of the pitfalls of being the first (or only!) person in an instance to subscribe to a community: https://lemm.ee/post/37715

Edit 2: Found https://github.com/LemmyNet/lemmy/issues/3055 requesting better support for discovering federated communities. Please consider upvoting that issue if you have a github account and think it would be helpful!

I made myself a lemmy: https://tortoisewrath.com

You may notice I am not writing to you from said lemmy... because https://tortoisewrath.com/c/selfhosted@lemmy.world is a 404. In fact, though it appears to have federated itself with a bunch of other servers, it only appears to be able to see two communities. These were among the first few communities I tried to access (technology@beehaw.org didn't work but those two did) - since adding those two, I haven't been able to see any others, even on lemmy.ml where the first two were.

Is this normal? Do I just need to be more patient and it'll figure it out on its own, or is there some switch I need to flip to make it do the thing?

(Apologies if this is obvious to those who understand the fediverse but I have no idea what I'm doing)

Oh interesting. I could selfhost and then have access to any of the instances? Would I be able to access an instance that's defederated? Seems like Beehaw has a ton of activity and now it's defederating. It's almost sus bc if I was trying to discredit the fediverse and Lemmy in general, I would get as many people on my instance as possible and then cut it off completely.

It depends. If they are choosing only to defederate specific instances, yes. If they are choosing only to federate with specific instances that leaves it up to you getting on the list by talking to those instance admins or something. If they are not federating at all then of course you're just out of luck.

Re. Beehaw: It's impossible to guess their intentions at this point. They appear to be (and say they are) only defederating specific instances and they are doing so for specific reasons. As I said to someone else talking about this just as it happened:

(Originally comparing this to some of the instance blocking that happened back when I ran a Mastodon server)

Insular communities gonna insulate. Defederation has collateral damage, but among some communities that is acceptable because they view intolerance and the toleration of intolerance as close enough to warrant blanket handling. (See that “Nazi bar” story that’s often cited)

(Then talking about how that relates to Lemmy)

IMO moderation necessarily has to exist two places in a federated environement. Yes, the community (hosting instance) always has to do moderation, but so does the federating instance. If the federating instance does not have policies in place to handle bad actors who go to other servers and break their rules and it is a large enough problem this action could make sense even well into the future. Unfortunately Lemmy is in a quite early state so I don’t think the tooling to do such work well even really exists. Something like only allowing confirmed posters from federated instance[s] or requiring someone to be subscribed for an amount of time before posting could do wonders. Yes, this is the nuclear option, but their choices at the moment are a butter knife or a nuke.

I sincerely hope this gets better as Lemmy matures.
