It’s doesn’t seem like feddit.online is aware of the other community (forumlibre@jlai.lu), so it doesn’t have a copy of both posts, so it doesn’t know that they are cross-posts.

If you bring that community into feddit.online, then create a post with the same URL as a recent post (e.g. https://files.catbox.moe/pebvir.jpeg), then they’ll show up.

The picture (or whatever external resource a post is pointing to, like https://bbc.com/news/article.html)

The post you mentioned (‘melting is tough’) isn’t picked up as a cross-post on PieFed instances because the dates are too far apart. A restriction that Rimu wanted was that they should only be detected if they were within 7 days of one another.

However, if you take that URL (https://lemmy.world/pictrs/image/91f96cc8-a194-4cb8-abc6-505261e65420.jpeg), and make a new post with it, then the post you mentioned now shows that it has a cross-post.

A cross-post is just a post that links to the same URL as another post. The codeberg Issue that Blaze linked to mentions an exception, but other than that, there’s not a convenient button that copy-pastes a post’s title, body, and URL into a new ‘Create Post’ form. You can do it manually though, and everything that receives it will detect it as a cross-post, because everything is just looking for matching URLs.

Photon came up in this discussion amongst the Lemmy developers.

Maybe it was Neon Modem Overdrive, or this TUI app.

But, yeah - shell browsers like the ones you mentioned don’t support JavaScript, so won’t work with Lemmy (as it currently is - it might be different when they start using the leptos-based UI). There’s places where they’re not great with PieFed either (e.g. link2 -g can’t deal with WEBP images), but it’s completely theme-able, so a theme could easily be added by someone suitably invested to overwrite the existing HTML and provide a better experience.

If an admin bans a local user, they’re banned once, but if they ban a remote user, the way Lemmy currently handles it is to ban them from every community they’ve subscribed to. There’s an Issue about it because it’s a hacky and incomplete solution. As such, the ‘banned 20 times’ thing isn’t something that people should read too much into.

That link shows loads of apps I’ve never heard of, but visiting their repos suggests that they’re dead.

Since that site helpfully breaks down platforms by programming language, it might be best to target something familiar (or maybe something you want to learn).

This community is hosted by Lemmy (Rust), and most of the posts and replies will be made by people using that, but they’ll also be some by people using PieFed (python) or MBIN (PHP).

The 4K Blu-ray remux of Andor Season 1 is 230 GB. This new government might be shutting down the internet, but I doubt that they’re monsters, and so surely wouldn’t expect me to re-watch it in any lower quality. Fortunately, I’ve worked out that the Aldanhi arc and the last 2 episodes are 102 GB, so it should be manageable if some recaps are cut.

I assumed that was there because there are some sites (e.g. reuters.com) that make it difficult to automatically grab a thumbnail image to go with the article. So if you’re posting a link to somewhere like there, you’d find a relevant image manually, and use that field so the post you make will be more engaging.

I don’t think it’s for posts that are an image - in that case, the software can just use that to create a thumbnail, so it doesn’t need the extra help.

Is there a more modern alternative to embedding videos in plain HTML? It’s easy to use them for embeds from youtube and peertube, streamable, etc.

Ah, I see now, thanks. That makes more sense than my previous theory, that MBIN users were pathological liars or something. Also, now my previous comment makes me look like an idiot. Oh, well.

It’s interesting what MBIN does - making the user click a button gives it an extra chance to query the remote site, so it can render it correctly. That’s not the same as taking the markdown and rendering it as HTML, but the end result is nice.

Elsewhere (like on PieFed), Youtube embedding works well because the URL is in a nice dedicated field, so it’s easy to process, rather than parse through the text of a comment to find it. No idea what’s happening with Tesseract, but it’s just a front-end for Lemmy (albeit a sophisticated one), so my guess is that your link would fail, but since the comments aren’t there, it’s a bit moot.

I’d be surprised if that test worked on any platform in existence. You’re using the markdown to render a static image, and sticking a youtube URL in there. PieFed supports it if the URL ends in something like .mp4, but that’s only because Lemmy have fudged it, and so now people expect it. There’s meant to be a 1:1 relationship between markdown and HTML, metadata transformed into metadata - nothing should have to look at the actual contents to know what tags to produce.

As for ‘works for me embedded in mbin’ … eh? It looks like this in mbin:

That’s literally just a external link to youtube. It ‘works’ because it doesn’t - same as for the screenshot itself - instead of embedding it, it just coughs up the link to a remote site. Everything else is rendering it as it is - a broken link to an image that doesn’t exist.

(maybe ‘originallucifer’ has some fancy app that takes a youtube shorts URL, works out the embed code, and then puts it in an iframe … but like I say, I’d be surprised).

For the one rogue fuck, my Rogue One fuck would be:

A fair bit of Mastodon content doesn’t fit well on Lemmy. One mundane technical reason is that their posts don’t always split up well into the post title / post body that Lemmy expects. A cultural reason is that Mastodon users have a much higher tolerance for other users promoting things like their patreon than Lemmy users do. Even if the posts split well, and is content that Lemmy would like, bringing in the replies to it opens up a spam vector.

Lemmy let’s you impersonate other users. I used to do that with https://lemmy.world/c/[email protected], but stopped because the above-mentioned reasons made it tricky to automate (and because I got bored with it)

I think you’re remembering wrong. The communities that have moved so far have been a manual affair: a post on the old community with a “We’ve moved” post, locking that community, and starting up brand new somewhere else. It’s a fresh start - nothing is migrated. It’s very likely to be technically impossible to move communities in the way you’re imagining.

Skirt + poncho = double skirt
Denim skirt + denim poncho = double denim double skirt.

Oh wow - I never realised that lemm.ee had got so far behind. That problem seems to be in the past now, and posts will only be missing from there if they’re relying on world to send them.

As the post that Blaze linked mentions, LW is catching back up now (it’s only if the delay gets over 7 days that you need to worry about them being lost)

Hypothetically, sure: the info exists in one place - they’d just have to arrange a way to transfer it.

Votes themselves are a simple activity, but each one can cause a surprising increase in storage requirements (every vote has a user, every user has an instance, every instance has admins, and all these entities might have avatar and banner images associated with them). Most instances are run by one person as a hobby, and paying for DB and image storage seems to be the no. 1 reason for instances folding, so there’s generally a question of how much one instance should be an exact mirror of another one.

You’re correct in assuming that nothing is stuck in a queue.

Compared with other Fediverse platforms, a feature that Lemmy lacks is paginated outboxes. These would allow communities to list all the posts, because other instances could get them a page at a time (e.g. 20 for page 1, then the next 20 for page 2, and so on). Instead, they provide a non-paginated outbox with only the most recent 50 posts. An outbox for comments isn’t really feasible without pagination, which is probably why they don’t provide one at all. For votes, it’s even less practical, and irrespective of that, it would go against the familiar hang-up about votes being private.

So if you’re the first person to join a remote community, then 50 recent posts are brought in, but no older posts, no comments, and no votes. There’s no way to get the old votes. If your instance receives some activity that makes it realise that it’s missing something, then it will resolve it (e.g. it will often fetch an old post if it receives a reply to it, and fetch a comment if it receives a vote for it), but it will start that post or comment at score 0.

If you really wanted to be fully in-sync for comments, then you could script it to use the APIs for the remote and local instance. For the remote instance it would be something like: list the posts oldest to newest (limited by the amount you’re missing); get the ap_id for each one, then login to your instance and ask it to resolve it. Then do the same for the comments in each post. Everything it resolves would be a score 0 though, and it assumes that the author hasn’t deleted themselves in the meantime, or that their instance hasn’t disappeared. Given that, I don’t really see the point, other than trying to a completist about stuff.
