photos will never be pngs unless someone intentionally converts them to that format, as pngs are much worse than jpgs for storing this type of image. pngs are much better for computer generated images, such as screenshots, drawings, etc. you can also losslessly compress pngs with tools like pngcrush without converting them to jpg.
it’s like @[email protected] described. old content does not get federated unless there is new activity on it and someone on your instance is subscribed to the community it happens in.
this isn’t anyone’s fault, it’s just a matter of the instance not being around that long that some historic content will be missing.
this isn’t true. it was incorrectly stated in the upgrade guide but has been removed a while ago. it was supposed to be a recommendation due to some issues with postgres 15. there is no postgres upgrade required between 0.19 releases.
for sure, but they’re neither mentioned on https://join-lemmy.org/docs/users/02-media.html nor on the linked CommonMark tutorial.
It’s not even just that. It seems that the extra acts as a separator, so you can’t even autocomplete e.g. @threelonmusketeers@sh as that’ll try to autocomplete @sh instead of taking the instance domain as part of the mention.
I’ve raised a GitHub issue for this now: https://github.com/LemmyNet/lemmy-ui/issues/2652
on firefox, if i type @gedal and click or press tab once it replaces the text with [.world](https://lemmy.world/u/gedaliyah) .
the behavior is the same whether i hit tab, enter or click the text.
just as great as lemmy-ui
it does, but only if you use the autocomplete feature. it’s also a bit delayed without any indicator that it’s loading.
if you type @gedal and wait a moment it’ll load @[email protected] to be selected:
| if | you | want | to | get | fancy |
|---|---|---|---|---|---|
| you | can | even | use | undocumented | tables |
Except it wasn’t created on lemmy.ml, it was created on lemmy.world.
lemmy.world then informed lemmy.ml that it is intended to be published in the community that it was created for.
It doesn’t say “crossposted from lemmy.world” but “crossposted from canonical_post_url”. This is not wrong in any way, although it might be a bit confusing and could likely be improved by including a reference to the community. The instance domain should for the most part just be a technical detail there.
It should also be noted that this format of crossposting is an implementation detail of Lemmy-UI and other clients may handle it differently (if they’re implementing crossposting in the first place).
I’m not saying it’s technically impossible, although it would likely be a bit challenging to integrate on the technical level, as the community instance has no authority to modify the post itself other than removing it from the community at this point.
The existing fedilink is already present for technical reasons anyway, so this is currently only showing existing data.
Why would you want a lemmy.ml link though? On Lemmy you’re typically intending to stay on your own instance, which many third party apps already implement. For Lemmy UI there is already a feature request to implement this, although it might still take some time to get done. If you have the canonical link to an object (which will always point to the users instance) Lemmy can look up which post/comment you’re referring to in its db without any network calls when it already knows about the entry. If you were linking to the lemmy.ml version of that post then the instance would first have to do a network request to resolve that and then it would realize it’s actually the lemmy.world version that it may or may not know about already.
it doesn’t matter whether you consider it reasonable, as it’s this way for technical reasons.
when a post or comment are created they are created on the users instance. the users instance then tells the community instance about the new post/comment and the community instance relays (announces) this to other instances that have community subscribers.
the fedilink is an id and reference to the original item. this unique id is known to all servers that know about this comment and it is what is used when updates to the post are distributed. except for the reference to the item on the originating instance, no instance stores information about where to find a specific post/comment on a random other instance.
The “fediverse link” on a post always points to the instance of the person who posted it, not the community instance. When posting from a lemmy.world account this means the fedilink is always the lemmy.world post link.
It is only shown for content coming from remote instances in Lemmy UI 0.19.3, although a later version changed that to always show.
It should be noted that the (visibility of) community bans are a result of better enforcement of site bans in 0.19.4, which for now is implemented by sending out community bans for local communities when a user gets instance banned: https://github.com/LemmyNet/lemmy/pull/4464
Prior to this, when a user got instance banned from .ml, they were also implicitly banned from .ml communities, but this was only known to the instance they were banned on. As a result, users were still able to post, comment, and vote on those communities, but it would be visible only on that user’s instance, not federated anywhere else. Visibility of this ban was exclusively on the banning instance’s modlog.
I’m not familiar with n8n but it’s fairly straightforward on the API side.
You’ll need a session token, also known as JWT, which you can get from logging in.
You typically don’t want to do a login for every post, so you’ll want to store that as a persistent value.
For authentication, you can pass the header
authorization: Bearer {jwt}, with{jwt}being the session token.https://join-lemmy.org/api/classes/LemmyHttp.html contains the API documentation.
You’ll need to figure out the id of the community that you want to post to.
If you need to look it up, you can use getCommunity to fetch its details. Afterwards you can use createPost to submit it.
The
formlinks for the methods explain the request body json values that should be provided.
