Can someone explain to me what is the link between Mastodon and Lemmy? From the Wikipedia chart, it looks like ActivityPub links them together in some fashion; I just don't get how.

@pankkake @ubergeek77 I'll actually use this as a an opportunity to test something - I copied your comment's link into mastodon and am replying to it with my mastodon account. I can see the thread in mastodon, and in theory, this reply should show up properly in Lemmy too.
It looks no different than any of the other comments to me. Though I haven't been here for even a day, so... :))
Yeah so it seems to work! Pretty cool that I can do that.
Do you have any idea how upvotes/downvotes get mapped to boosts and vice versa? I "followed" a couple of lemmy subs and I can see that they are boosting certain comments on posts in my mastodon feed.
In theory, Lemmy and Mastodon are compatible with one another, as they both use ActivityPub.
In practice:
Mastodon users can only see Lemmy posts as Boosts ("retweets"), and from what I hear, it's fairly annoying and not a good experience
Lemmy users can't see anything on Mastodon at all, Lemmy doesn't have a way to federate with Mastodon instances yet.
This is the first time Lemmy has seen this many users ever, so I'm confident both of these issues will be fixed sooner or later. When they are, you'll be able to see Lemmy posts on Mastodon as if they were posts ("tweets"), and you'll be able to see Mastodon posts on Lemmy as some kind of post (not sure if the format has been decided yet).
Just to clarify, Mastodon users can already make posts to Lemmy communities, just not the other way around yet.
Definitely agree it's not a good experience yet though.
It'll be great when fediverse will become interconnected open ecosystem
I'm really interested in the idea of these different kinds of websites being interoperable because of ActivityPub. Like the different websites are basically different frontends for people who prefer link aggregators or micro-blogs or other kinds of websites. It's a really cool idea!
Okay, so it's not really implemented yet. Can't wait until federation is more profoundly implemented then!
Thanks
@ubergeek77 @pankkake you can comment and make lemmy posts from Mastodon and others. I'm on Friendica for example and made this comment from my Friendica profile.
How did you find this post ?
It's all a little arbitrary. When you create a new service (like Lemmy, or Mastodon), you can have them link with anything, in any fashion you like. The defaults are mostly sensible.
For example, I've just made a mastodon post asking /r/casual a question. Once that synchronizes across, you'll see the topic over there.
I would like to add to your picture yggdrasil and matrix based messengers, as this will help infrastructure to be more robust and expand
The only problem with federation is duplicate communities, and I donβt even see that as being necessarily a bad thing. Iβll subscribe to multiple communities for the same thing and if, over time, I end up getting annoyed with some of them Iβll just unsubscribe.
Yeah, I think it has a certain charm. However I fully agree, without it being addressed this will lead to issues and setbacks in the future trying to build communities. For now I'm subbing to all and trusting the process that creases will eventually iron themselves.
I think, kept this way, instances should be more clear what kind of 'country' they want to form. For example a group that has tech as the primary interest, should go about starting the instance as such, and setting ground rules for communities therein. Tech related, even if loosely, and differentiated from the masses. Or a better example would be, a European - English Instance could require a suffix like EU or UK like newsUK or photographyUK simply to attract the more locally relevant audiences.
A more involved solution could be to tag your community like Twitter into topics it wants to show up in feeds for (as well as tags that exclude it).. like 'technews' tagged in the 'news' and 'technology' but excluded from 'politics' and 'finance' and 'onion'
Another one could be to allow communities to federate with one another. If a news community spots some large news audiences in other instances, the moderators for each community could federate with one another and create a supercommunity (like a multi on Reddit), allowing the super to operate on both instances but share hosting of something along those lines.
You could also have moderators agree to join forces by migrating one community over to the larger server and closing up shop. This may happen naturally with time.
We have to solve the content curation problem IMO. If we all love lemmy.world or sh.itjust.works and post 1000's of hours of content to either and one of them just "shutters" the server then all that content is GONE. Or, am I missing something about how all this works?
If we want to "join" servers we need some type of content migration tool that allows the user to determine where their content is actually "hosted".
We may see individual servers for heavy content creators as they'll want some way to ensure that all of the federated servers can continue to access their content right?
Yeah good point actually. Independent servers is a strength but not future proof. Allowing larger servers to store back ups that other instances can link to in the event of down time, or allowing themselves to be absorbed if they shut down would keep the place running, there would just need to be a system in place where an instance can nominate another instance to hold a spare set of keys, so that duplicates don't start fracturing the system.
It's fractured by design. There are good things about being fractured. What we actually need is a "fractured" system with an aggregator to ensure the best user experience. You've heard of a system like this before: Cryptocurrencies are by nature 'fractured' but they use the term 'decentralized' and it's what brings safety and security to digital assets. What we need is a "Coinbase" or a "Binance" who "aggregates" all of the "coins" so that a user can just go to the exchange and see ALL of the digital currencies without having to know each of their names and server addresses in advance.
It's not necessarily a bad thing, but especially with the amount of news users (and subs) migrating from Reddit there is a certain potential for chaos for sure.
However, for me the pros of this approach still outweigh the cons as, like you said, it also provides more choice with which community you want to interact.
Like chess, but are a bit tired of googling en passant? Just find a community, that is more focused on the game on a different instance.
I mean reddit had tons of duplicate communities already. How many gaming subs were there?
Create a username on some other instance then search for the intsnace on lemmy.ml and just subscribe and post and comment. So much easiter. When i started yesterday i started with lemmy.ml but was like why is it so slow. realized that it just goes up and down so i created a username and lemmy.world and haven't looked back
So can you use the same username on a different instance, or do they have to be globally unique? I decided to be polite and pick a small server to sign up on, but it seems to have limited connection to other instances.
I believe the names have to be unique on the instance-level, but not on the federal-level. So test@lemmy.world and test@lemmy.ml are two different and valid usernames.
I did the same. Started on .ml then moved to .world to spread the load. Also heard some things about the mods on .ml
All those users who were told "Please move from lemmy.ml to somewhere else. It'll crash. Please spread out" are now seeing why :))
I saw a reddit post about alternatives and lemmy was what stuck out the most, and then there was another about how it works (not that indepth) and from there I got to lemmy.world and been here since yesterday
Agreed! I was intimidated by it at first but it's fast, I love how decentralized it is (although finding THE sub-lemmy you want will take some hunting) but I think it's pretty brilliant. I'm proud and excited for all our communities who are taking control of their own destiny!
Can you tell me how I can search for a sub-lemmy? There are a few I think have been started, but I don't know how to search for them without knowing what instance they are on.
If you haven't figured this problem out yet, you want to go to your home instance, click on the communities tab, and then search for a topic or community name that you want. The results should include all instances that your home instance is federated with, and you'll often have communities from multiple instances to choose from
Thanks for responding. That is how I was searching, but there was a problem with the indexing across instances.
Could you have been searching for communities on defederated instances?
I'm honestly surprised at how useable Lemmy is as a whole. Mastodon shit itself during the Twitter migration. Idk if it's just a lower volume of users or what.
Mastodon is written in RoR, whereas Lemmy's backend is in Rust. It's an order of magnitude faster just by being a compiled language with lighter-weight middleware.
I haven't used Ruby/RoR in half a decade but even in the early 2010's it was memingly slow compared to many alternatives.
Federation was very hard for me to comprehend at the beginning, but it all clicked once I read a little of the documentation.
For me it clicked instantly after reading e-mail analogy.
I'd love to hear this e-mail analogy.
This is the one that clicked for me credit to Matthieu@piaille.fr
You can think of it like emails.
A lemmy community is like an automated mailbox that sends everything they receive to all subscribers.
You can host a mailing list/community on gmail.
Then you can subscribe to the mailing list from outlook.
Then a user can send a post to the mailing list from yahoo.
The automated mailbox at gmail will receive the message from yahoo and send it to outlook and all other subscribers.
Likewise, it was feeling a little dry here today and I finally figured out the same thing you did. Being able to subscribe across many servers is wicked sick, and having an instance sitting "in front" of them the way we're using it makes it slick as heck when those other instances are unavailable or spotty.
It would be great if the instance kept a pulse on how federation to other instances is going and showed a health check in the app sidebar and near instance names to temper user expectations.
