For clarity, it’s not Lemmy that uses ‘Article’. I can’t remember what does, friendica maybe?
Lemmy uses ‘Page’ for posts, and ‘Note’ for comments.
Mastodon uses ‘Note’ for both, with ‘inReplyTo’ used to distinguish whether Lemmy would call it a ‘Page’. It uses ‘Question’ for polls.
Pixelfed also uses ‘Note’, with an ‘Image’ type attachment (I thinks Loops is similar, just with a ‘Video’ type attachment).
PeerTube uses ‘Video’.
Funkwhale uses ‘Album’ and ‘Playlist’
CastoPod uses ‘PodcastEpisode’

There’s no one universal ActivityPub server because the Fediverse is based on a broken promise: i.e. that you should be able to use whatever service, to interact with whatever other one. You very often can’t, because ActivityPub hasn’t been implemented by each platform as some universal thing, it’s been co-opted by each to serve it’s own purposes. Lemmy best federates with other Lemmy instances, following Lemmy’s way of doing stuff, but a good chuck of the Fediverse follows a different model, and is receiving their activity and quietly discarding it because it doesn’t know what to do with it. If all the Lemmy instances suddenly chose to use a different protocol than ActivityPub, most people wouldn’t notice the difference.

Garbage in, garbage out. If you look up ‘hansenerd’, they’re at https://shoddy.site/@cg - where it shows they joined in 2042.

Lemmy’s backend should probably be the one to sanitise it rather than each app.

Hmmm. I’d imagine that’s essential for cloudflare to work. You can get their IP addresses if you have a server that is federated with them and you look in your nginx logs (so that ‘if’ is a big IF).

Just matrix.org, like some kind of pleb.

I only have an account so I could join in one room, and that’s the server that the room was on, so I decided to keep things simple.

Ah, great, thank you. It’s been added as an Issue for PF now, with a link to this post, so that’ll be handy.

(I was likely misusing the term ‘regex’).

There was a post relating to this the other day: Some explicitly single-user ActivityPub software to check out

How does Piefed handle image attachments, btw?

For comments: not at all. If a Mastodon user tried to do what I did, with the inline image, nothing would show.

We could do what I think you’ve done, and regex the details of the attachment into ! [] () Markdown and add it to the text. There’s also a DB relationship between comments and images that isn’t used, but could be, I suppose.

I’ve never actually seen a Mastodon user try to add an image to something that ended up as a Lemmy comment, tbh, so it’s not something I’ve thought too much about.

I just tried with Masto - maybe there’s different versions, but it didn’t work with the one I tried.

Screenshot:

It’s probably for the best that this PR doesn’t also convert inline Markdown into an attachment to send out for Mastodon’s benefit, because then there would be the danger of apps that understand both showing two images. It’d be better if Mastodon did the translation when receiving stuff, but Mastodon doesn’t seem as good as MBIN when it comes to co-operating with Lemmy.

(edit: how that screenshot shows on MBIN is a bit disappointing though - at least looking at on the web)

Do they work the other way around btw? If someone on Lemmy uses the Markdown for an inline image do they show up on MBIN? I don’t they do on Mastodon.

https://literature.cafe/ is still running.

FWIW: that post is not for 2 communities - it’s for one community (/c/test at sh.itjust.works) and one user (/u/test at lemmy.ml) - I’m guessing that it’s autocompleted to a thing that was different from your intentions.

(edit: the webfinger response from lemmy.ml for ‘test’ returns both a Person and a Group, which Lemmy can deal with, but Mastodon probably can’t, so it just grabbed the first one it saw)

Last time that happened to me, it was because the ‘name’ I was using was too long (I removed some characters and it worked). There isn’t the same limitation for the ‘display name’ field though.

There used to be one - https://lemmings.world/u/communitylinkfixer

It looks like it was de-activated 3 months ago.

If you make a new one, please consider limiting it to just this community (and maybe communitypromo), and to not translating a link if the OP has also already provided a ! one, and to not translating links inside code blocks.

Drive-by bots can seem easy to make, but the problem is that they can be a bit too easy, and then end up as yet another annoying one.

Well, there’s the The 90-9-1 Rule for Participation Inequality in Social Media and Online Communities, which suggests:

Summary: In most online communities, 90% of users are lurkers who never contribute, 9% of users contribute a little, and 1% of users account for almost all the action.

So whatever number you’re looking for, it’s 1% of that. Not that subscriber count means much, especially for older communities that have 10’s of thousands of subscribers who aren’t even using the platform any more.

That comment chain demonstrates a real appeal of Reddit. Even for something like a post-episode TV discussion, a critical mass of people means that not only can you have the discussion in the first place, but there might be some extra info from someone who worked on the set, or attended an audience taping.

You can click to see the rest of the comments to see plenty wrong with Reddit too, but it’s not like there’s any particular drive to prevent the elements of Reddit culture that I find annoying from coming to Lemmy too.

I’d be surprised if there’s ever a critical mass of people on a federated app though. If there is, it’s more likely to be on something with the proper funding, that hides the details from regular users (e.g
it’ll be BlueSky, not Mastodon). On Reddit, Lemmy has a reputation for being too complicated, for the mundane reason that is. Too much stuff that should happen doesn’t, and the answer to why are the stuff that ‘normies’ don’t want to hear (LW and PD instances are both a bit unstable atm), or they’re so unintuitive that that they’ll need answering forever (e.g everything around discussion languages, instance blocks, newly-discovered communities , etc etc).

I’ve just seen a user accidentally submit the same post to the same community multiple times (the worst I’ve seen is 4 times). Preventing that is some real ‘web dev 101’ shit. Federated apps can be an interesting hobby for inexperienced devs (like me), and mildly diverting for anyone who wants to use them as a user, but a critical mass of users?! Forget about it.

Nope. Just tried on moist.catsweat.com and it says “Please select an item in the list” for the “Select Magazine” box if you try to post something and leave that empty.

I’m assuming that this is about your earlier post that ended up in LW’s technology community. Microblog posts like that seem to be more intended for whoever is following you as a user. If MBIN insists that you also have to choose a ‘sub’ then I think it’d be best to put it in whatever it considers a dumping ground (ideally something that doesn’t federate out), so the ‘random’ magazine sounds about right to me.

The communities aren’t super-active because the idea is that they’re remote-only, but that means they don’t get the benefit that comes from local users browsing their local feed.
