What do you notice about the comments on this post? https://piefed.social/post/555259
The post was made in the news@lemmy.world community and other posts linking to the same news article were made in technology@lemmy.world and in askusa@discuss.online. 3 different posts in 3 different communities.
PieFed de-duplicates them and only shows the post once in the timeline and when viewing the post all the comments on those 3 posts are shown in one place.
The fragmentation problem is solved.
What happens when three different users post libks to the same article? Or when the test is different? Basically how do you match these posts?
They are matched by the url of where the post links to. So this only works for posts that have a url, not discussion or image posts.
Ok so exactly how mbin spots cross posts at the moment. But combining the comment sections is a cool idea. Obviously requires your server to be subscribed to the different communities, but still cool 👍
Yes we had a lot of inspiration from Mbin for this one.
So that’s why cross-post won’t be available everywhere ? Only certain use case ?
Yes, url is the only reliable way I could think of to match posts.
For image posts we could use a hash of the image data. But image cross-posts are not common so it doesn’t seem urgent.
You could add linking to the same post, eg crossposting, to the criteria.
The urge to switch my server to piefed grows bigger every day.
Okay, thank a lot i understand better. Perfect. :)
We use crosspost for english meme however a multi-meme community will solve it. If we regroup them in a topic, we won’t need crosspost.
I wanted to use it for Peertube. The only problem i see is that [comment on a crosspost] won’t post comment on the peertube video.
And if we comment their video, that would solve peertube problem : they have no comments on their video.
what happens when there’s 2 different posts in the same community with the same URL, example:
https://programming.dev/post/8880813
https://programming.dev/post/1721399
(I can’t find a more recent example right now)
Those comments get merged into one tree. I think, didn’t actually test that.
This is or at least was a problem with cross-posts in the same community in Lemmy as well. I think now Lemmy just prevents posts with the same URL to be counted as crossposts when they are in the same community.
