When I first new about lemmy, lemm.ee was among the biggest and I created an account on it but didn't use it much and didn't knew that the instance was deleted until recently. So help me understand where content is stored:

  • When a post is created, is it only stored on the original instance, or copied to every other one?

  • Do all federated servers get a copy, or get posts from other server when user demands them?

  • When an instance shuts down, is its content gone forever, or do other instances keep copies?

  • If the original server is gone, what happens to edits or deletions?

  • Is there any kind of “shared” storage in the Fediverse, or network that store everything?

  • Could one still access all lemm.ee content now? Or post in it's communities?

So far no one has mentioned this, but typically images or other uploads only exist on the original server. When lemm.ee went down, all the content those users uploaded was lost.

The text content of posts and comments is copied across all the linked servers, but the images aren't. Some instances will proxy images from a short term cache, but it's far too expensive to store the images permanently.

When a post is created, is it only stored on the original instance, or copied to every other one?

Copied

  • Do all federated servers get a copy, or get posts from other server when user demands them?

They get copies of all posts from communities their users subscribe to.

  • When an instance shuts down, is its content gone forever, or do other instances keep copies?

The copies remain. But new comments or posts won't federate to other copies.

  • Is there any kind of “shared” storage in the Fediverse, or network that store everything?

No,

  • Could one still access all lemm.ee content now? Or post in it's communities?

Yes, as long as an instance that was around long enough to federate with it still exists. You can browse from SJW for example.

I’m new to this place…I still have no idea what’s going on and little idea of what an instance or my instance is.

…but I’m an OG internet user and what you’re describing sounds like ~~EchoNet~~ FidoNet?, or one of the various networked BBS systems pre-internet. BBSs, or groups of BBSs would frequently drop in and out of the networks, and the forums/threads from the absent BBSs would still be there…but in a “cleaved” state. Very confusing to a user who used multiple ‘Nets (which was everybody).

[-] can@sh.itjust.works 2 points 3 months ago

My explanations may not have been new user-friendly. So we're on the "threadiverse" as some of us call it. Lemmy is the biggest software that's compatible but there's also mbin, and piefed. You're signed up on a piefed server (instance). But you can still interact with Lemmy users, communities, etc. And vice-versa.

The only difference is your UI and admins.

Is there anything specific I can clarify?

[-] MyMindIsLikeAnOcean@piefed.world 5 points 3 months ago* (last edited 3 months ago)

Thank you.

I sort of get it. I get the concept. I don’t really understand what I have access to in addition to “Lemmy”. I get that my interface is different because I use Blorp…I get that whatever address a user is posting from comes with a set of admins that moderate their users and choose what instances they see. I guess I don’t get the scope of the whole thing or what I’m not seeing and why. I sort of understand that the “channels” are hosted on particular instances.

I’m a refugee from Reddit and instantly preferred this because I don’t get random automatic false positive warnings from the system, and there no mods harassing me and abusing the auto moderation system….so far. Maybe because everybody isn’t a bot and/or picking a fight with me.

[-] can@sh.itjust.works 4 points 3 months ago

Is Blorp an app? You're registered on a piefed instance which has some more features than Lemmy and a different website UI but we're still compatible. You can use this site to search for communities.

One of the best features in my opinion is the modlog.. If any mods are abusive we can see it and take action.

[-] MyMindIsLikeAnOcean@piefed.world 4 points 3 months ago

Yeah…it’s the app I use. It’s pretty slick.

Interesting…I’ll check both those out. 

[-] moseschrute@lemmy.ml 4 points 3 months ago

Blorp dev here. Thanks for using my app! Let me know if there is anything I can do that will make it even better for ya!

[-] MyMindIsLikeAnOcean@piefed.world 1 points 3 months ago* (last edited 3 months ago)

No complaints, and thank you very much for making it.

The only thing I can think of is when I open the app I’ll sometimes see a post I’m interested in…but the feed will refresh, and I can’t find the post again. It’s not common the first post is one I’m interested in, I just don’t always remember to not look before it refreshes - so it’s mildly annoying. Not a huge deal.

[-] can@sh.itjust.works 2 points 3 months ago

Another thing to keep in mind is votes are obscured, but not really private. Admins of federated instances can see them and there are tools too. Piefed might work a little differently. There's an option to not have your votes federate to other servers so only your admins can see it.

[-] MyMindIsLikeAnOcean@piefed.world 2 points 3 months ago

Thanks.

I never really paid attention to votes…not even on Reddit. I’m old and I just say what I say. I’ll hand them out to reward effort…but beyond that the count miss me.

[-] can@sh.itjust.works 2 points 3 months ago

I feel the same way. It was a relief when Lemmy didn't keep a "karma" count on my profile.

[-] moseschrute@lemmy.ml 3 points 3 months ago

I’m the developer behind Blorp. Initially it was a Lemmy client, but as I add support for more piefed specific features, I feel more confident saying we have 1st class support for Lemmy and PieFed. 

[-] can@sh.itjust.works 1 points 3 months ago

Nice! Keep it up.

[-] can@sh.itjust.works 2 points 3 months ago* (last edited 3 months ago)

Also, with regard to abusive mods. If you do notice anything, please let us all know !yepowertrippinbastards@lemmy.dbzer0.com

His instance and mine, "sh.itjust.works" was federated with lemm.ee

[-] can@sh.itjust.works 7 points 3 months ago

I missed one:

If the original server is gone, what happens to edits or deletions?

Edits or posts made after the server is gone? They don't federate out past your instance.

[-] cole@lemdro.id 14 points 3 months ago

please remove the AI sentence before the questions in your post

[-] Carl@hexbear.net 6 points 3 months ago* (last edited 3 months ago)

I don't know all the details, but it looks like every federated server will save its own copy of the now-deleted server's posts in its archives. Here's a post from lemm.ee that's still visible on Hexbear as an example. Given this knowledge, I bet you could recreate lemm.ee with a script that gets the data from all of the servers it was federated with.

Since I don’t understand whatever Asian text I accidentally pasted, I have no idea what these upvotes are for.

Sometimes deletions don’t federate to every instance, and this is one of those cases.

Edit to add: Apparently it’s Japanese for library.
I was trying to test out a little-known markdown-it-ruby feature: {図書館|としょかん}

[-] HiddenLayer555@lemmy.ml 5 points 3 months ago

Does the official Lemmy source code actually delete data when a delete activity comes in or does it just stop displaying it? Just curious.

[-] davel@lemmy.ml 6 points 3 months ago* (last edited 3 months ago)

We know they don’t get deleted because otherwise the undelete feature wouldn’t work.

[-] HiddenLayer555@lemmy.ml 2 points 3 months ago

Does editing the post overwrite the old contents or is it like a git repo and just creates a new version with the updated contents? Basically, does editing your comment before deleting even do anything privacy wise?

[-] davel@lemmy.ml 1 points 3 months ago

I don’t know and am too lazy to go read the code, but it probably overwrites because that’s the easiest and most efficient way, and there’s nothing to be gained by retaining the old versions in this case.

[-] SuperApples@lemmy.world 2 points 3 months ago

As someone regularly uses Japanese and sometimes uses node.js, this is a handy library to know about! Cheers!

[-] ahriboy@lemmygrad.ml 2 points 3 months ago

Instances should have given everyone 3 months to migrate before closure. This is very important for the microblogging part of Fedi, I faced a notice and then I migrated one of my headmates to kitsunet.net.

They are sold for LLM training sets.
