I was wondering what was going on with that post. I’m glad it resonated with people across the fediverse. Cool!

Now I’ve got to figure out how to log into Mastadon with my Lemmy account. I didn’t even realize this was a thing.

[–] anafabula@social.anafabula.de 52 points 9 months ago (1 children)

@maxprime@lemmy.ml You can't log into other Fediverse services using your Lemmy account. It's a Lemmy account for your specific Lemmy instance and doesn't work anywhere else.

What you can do is talk to people on other Fediverse services with your Lemmy account on your instance in the same way you are communicating with people from other Lemmy instances.

For example, the op you are replying to is using Friendica, you are using Lemmy and I am using Firefish right now.

I like to explain it like email or even phone providers. You can call someone on Verizon even if you're on ATT but you can't pay Verizon for your ATT bill

I wish Lemmy would make instance agnostic post and comment links. With the current system it's impossible, as every instance assigns its own number. Instead, links could be in the form https://your instance/comment/number@hostinstance

[–] Die4Ever@programming.dev 23 points 9 months ago (1 children)

The GitHub issue is here, you could put a thumbs up reaction on it, and also subscribe to the issue to get updates about it

https://github.com/LemmyNet/lemmy/issues/2987

[–] TWeaK@lemm.ee 11 points 9 months ago* (last edited 9 months ago)

Done. I hadn't seen that issue before, not that I really dig into github all that much.

However the issue is somewhat outdated. We do have instance agnostic links for communities and users now, and we have since I joined, which was less than 2 weeks after this issue was posted. We may need a new updated issue that focuses on posts and comments specifically.

[–] Masimatutu@mander.xyz 10 points 9 months ago* (last edited 9 months ago) (1 children)

While I completely agree, a partial solution is to use clients that open fediverse links locally. I use Eternity which does it nicely.

[–] otter@lemmy.ca 9 points 9 months ago (1 children)

That works for a Lemmy user, but it doesn't help for sharing on other platforms or for users discovering content elsewhere

[–] Masimatutu@mander.xyz 1 points 9 months ago (1 children)

Yeah. I really hope someone writes a Firefox extension or something which automatically redirects all Fediverse links to one's preferred instances. Enforcing a standard across a giant decentralised network is difficult.

[–] otter@lemmy.ca 5 points 9 months ago

There are a few extensions, but I don't think there's one extension to rule them all yet:

[–] Dave@lemmy.nz 4 points 9 months ago (3 children)

It could just be a GUID. The community's host instance assigns a GUID (which by definition is unique in all GUIDs) and then when sending the post or comment out to federate to other servers it includes the GUID for the other instances to use.

[–] Knusper@feddit.de 9 points 9 months ago

I'm a massive fan of GUIDs, too, but you'd have no protection from rogue instances reusing GUIDs of existing posts...

[–] BeefPiano@lemmy.world 6 points 9 months ago

But I still need a host to know where to retrieve the comment from. A GUID on its own doesn’t help if my instance hasn’t seen that comment. So if there’s a host already on the comment id, why bother with an ugly long GUID?

[–] TWeaK@lemm.ee 5 points 9 months ago (1 children)

I don't think there's a need for a GUID, in fact it would be quite difficult - every instance would have to check with every other instance to ensure that the ID's are unique. Meanwhile, if we just have the federated host picking a number, then every other host uses that number followed by @hostinstance, we don't need cross-checking but still have unique ID's for everything.

For example, https://lemm.ee/comment/123456 would be a different comment to https://lemmy.nz/comment/123456 (as it is currently also), but the first comment could be found on the 2nd instance as https://lemmy.nz/comment/123456@lemm.ee.

[–] Dave@lemmy.nz 3 points 9 months ago (1 children)

every instance would have to check with every other instance to ensure that the ID’s are unique.

No they wouldn't, that's the point of a GUID - they are globally unique.

However, I've changed my mind. For the nice-URL factor, having @instance is better and provides extra info.

[–] TWeaK@lemm.ee 2 points 9 months ago (1 children)

But they can only be globally unique if each instance has its own range of unique ID's, otherwise they'll have to check with the other instances to make sure the GUID they want to use hasn't already been used. With new instances spinning up all the time you can't really manage this.

I agree that the @instance provides a little more info, and it fits nicely in line with how user profile and community URLs are handled.

There was also a github issue report about putting the title in the URL, like reddit does, but I think this goes too far - lemmy has the ability to change the title and putting the title in the URL would just confuse things or lead to exploits (eg you put naughty words in the title then change it afterwards, but the URL still has the original title).

[–] Dave@lemmy.nz 4 points 9 months ago (1 children)

GUIDs are globally unique because of maths and clocks not because of checking. When you generate a GUID you can be confident no GUID the same has ever been generated using that algorithm, ever, anywhere, and you don't have to check.

However, someone pointed out you could run a malicious instance that copies GUIDs from other instances and federates them out to deliberately cause issues, so this idea is out.

[–] TWeaK@lemm.ee 2 points 9 months ago

Ah fair, I guess I misunderstood GUID's.

[–] Yamainwitch@lemmy.world 27 points 9 months ago (1 children)

This is so wholesome, the world needs to support teachers like this!

[–] Zoomboingding@lemmy.world 11 points 9 months ago (1 children)

Just echoing a class I had in high school.

My social studies teacher ran the whole year as "micro community." There were three different classes per year, and each class was a community. Each student had a role within the community, and performed actual job duties necessary to keep things functioning. For example, I was a banker and had to cash checks. After tests, we got checks based on test scores, so you got (fake) money to spend on stuff. We had to pay a utility bill or he would turn off the lights and not use the projector for notes. The kid running the power company would collect that money.

The best part was the stock market. Each community was also a company whose share value depended on overall test scores. So you could invest in whichever class you thought would score the highest.

[–] Yamainwitch@lemmy.world 5 points 9 months ago

Wow! That is so creative and thoughtful. I wish everyone has a teacher like that who truly loves the profession and respects the impact they have on their students' lives.

[–] kamen@lemmy.world 19 points 9 months ago

I hope this is real; and if it is, I hope there are more teachers like this.

[–] therealjcdenton@lemmy.zip 15 points 9 months ago

That's the most intricate way I've ever heard of someone trying to find a meme they once saved and can't find it

[–] Masimatutu@mander.xyz 12 points 9 months ago (1 children)

Update: I'm on Universeodon, which has comparatively modest numbers compared to mastodon.social. Mastodon.social has registered 249 boosts as of now! Favourites are difficult to measure but based on upvotes registered on lemmy.ml minus the ones registered by mander.xyz it'll be around 400. Way to go, Fediverse!

[–] steven@infosec.pub 3 points 9 months ago (1 children)

Is this how stats will be reported on the Fediverse?

[–] Corkyskog@sh.itjust.works 3 points 9 months ago

Somehow I hope not, and so, at the same time...

[–] sexeducation@fanaticus.social 11 points 9 months ago (1 children)
[–] scubbo@lemmy.ml 21 points 9 months ago

Mastodon is to Twitter as Lemmy is to Reddit.

[–] otl@lemmy.srcbeat.com 8 points 9 months ago (1 children)

Way to make me feel silly for having both an account on both a Mastodon server and a Lemmy server! ;)

[–] masimatutu@nerdica.net 23 points 9 months ago (5 children)

I love both Mastodon and Lemmy, but they usually don't federate very well with each other, so one cannot replace the other: Lemmy users cannot see microblog posts which aren't connected to any community and Mastodon doesn't show the body of Lemmy posts. Currently trying out Friendica, which manages all parts of the Fediverse reasonably well.

[–] otl@lemmy.srcbeat.com 5 points 9 months ago

Interesting - will look into Friendica. I just hacked up the latest stable release of Lemmy to run on OpenBSD but it’s not something I think I want to maintain long-term. Looking for something that will last a while, kinda like email but maybe not that long!

[–] Bebo@literature.cafe 3 points 9 months ago (1 children)

Is it possible to migrate from Mastodon to friendica? And how are the mobile apps?

[–] masimatutu@nerdica.net 2 points 9 months ago (1 children)

@Bebo
You can always migrate, but sadly there is no way to import your profile directly from Mastodon. The two best apps, Fedilab and Relatica, are fine but rather limited in functionality, so I often end up using the web version.

[–] Bebo@literature.cafe 2 points 9 months ago (2 children)

Oh I hope there is more development in the future since friendica sounds promising.

[–] maegul@hachyderm.io 3 points 9 months ago

@Bebo @masimatutu

Friendica definitely is one of the underrated fediverse platforms.

Many bounce off of it because it seems a bit slow and its UI is dated. But in terms of the general ideas about what the fediverse can be and the functionality it’s implemented, it’s very interesting and it would be awesome for it to seem more love.

@masimatutu

Yea. Generally a good demonstration of how the promise of the fediverse isn’t really there yet.

Lemmy does groups and mastodon does users with neither really understanding the other.

I think there’s more scope for lemmy to cover the user side of social media than mastodon the groups side. Kbin is an example of a continuing effort to do that.

If some keen devs got involved, I’d suspect lemmy could add some good user based functionality.The core devs have recognised it’d be good.

[–] Grant_M@lemmy.ca 2 points 9 months ago

Lemmy + Mastodon is a pretty great combo :)
