Lemmy Support

I'm currently on lemm.ee and I'd like to migrate to lemmy.eco.br, both are using the 0.19.5 backend version.

I remember reading some discussions in the past about being able to migrate instances, is it already possible? Is it being developed? How's the status of this feature?

Posts not appearing in communities when other group actors are mentioned.

Tried making a post (link below) to a lemmy community while also mentioning two other groups. My post never appeared in the Lemmy community.
This seems like a bug, when I tried posting to two lemmy communities at once the first went through, the second did not.

Does anyone know what's up with this?

@lemmy_support

Hello,

I'm new to setting up a lemmy instance. Followed the guide using docker compose. I have everything running for the most part, but I'm noticing this error in the logs.

lemmy-pictrs    | 2024-10-28T01:58:48.048727Z  WARN pict_rs::tmp_file: TmpFolder - Blocking remove of directory "/tmp/pict-rs/0192d0d8-e3ec-7dcd-be4e-d1ef1cc09fca/0192d0d8-e3ed-71d6-a5dc-5dc150e868f1"

Any help on how to go about debugging this would be helpful! As I understand the pictrs container isn't able to access the volume for postgres. But not sure why.

I try to get comment data for my posts via API from my Lemmy instance, but whatever I try on using the GetComments endpoint it delivers an empty array.

For example ... GET https://programming.dev/api/v3/comment/list?post_id=20878811 leads to:

{
  "comments": []
}

I want to ask here, before creating an issue. Has someone a hint?

Is there a nice guide somewhere? I'm imagining it'll ultimately amount to a CSS file.

I am thinking more relating to how on Reddit you can "message the mods"; is there any function like this on Lemmy, or do I have to message mods individually?

Whenever I try and upload an image, it does not work.

Somebody reminded me recently that if you resize the image and make the file size smaller, it will work.

I'm wondering if anybody knows what the actual file size is as a maximum that I can upload?

Rather than just wing it, I would like to create a script that will create the appropriate file size.

I don't want to be greedy and use up heaps of resources, but I'd like to find what the happy balance is and make sure it works within the limits of the system.

Thank you so much.

I recently blocked X instance, as I didn't like the users and content from there.

But to my surprise, X instance was still able to send me a comment?

Is this a bug? What can I do?

I know the issue has been answered before, but does anyone know if there exists some kind of work-around until the actual disable-image-upload is implemented in Lemmy?

Hey y'all,

I have a problem: sometimes I find a cool video on Youtube and I want to post it in a community I moderate. So I create a post, put the Youtube link in the URL field, and several options get added to the form:

• Copy suggested title:
• archive.org archive link
• ghostarchive.org archive link
• archive.today archive link

I click on the first one to copy the title, no problem. And usually that's it: I post, the post's preview shows a snapshot from the video and clicking on it sends me to the Youtube video. Great!

Now here's my problem: I would prefer not to link to Youtube directly So I tried replacing the direct link with any of the 3 proposed links, and it doesn't go all that well:

• The archive.org link seemingly never works
• The ghostarchive.org link works but no preview image is generated, which makes the post a bit boring
• The archive.today link redirects to a archive.ph link which is account-walled

Does anybody know how to create a post with a preview image that links to a Youtube video archived someplace else?

And yes, I'm aware that I could also report the video on my PeerTube. The problem is, SDF only has limited resources and I'd rather not upload huge videos there. They don't need the burden.

a user is getting all sorts of block and unblock notifications from a bunch of servers and communities.

I've heard that the standard Lemmy UI is not under active development because the Lemmy UI developers are working on a rewrite. I looked at it for a while though, and I thought that, aside from some missing features and polish, it was fine.

I'm trying Photon right now, and it is also fine, and a little more feature-complete, but it is visibly janky in some respects. Maybe it is my biases, but I also much prefer the model of clicking on things and getting a new page over a single-page app that you interact with via controls.

What was so terrible about the vanilla Lemmy UI? Do people really have a strong level of dislike for it? It seems to me like it just needs some love to smooth down the rough edges and awkward spots, but the core doesn't seem in any way terrible such that it would need to be abandoned.

One thing I liked (and sometimes disliked) about Reddit was that my feed was a mix of posts in communities I'd joined and a few suggestions of posts from subs The Algorithm™ thought I might like.

On Lemmy I'm realizing I'm starting to fall into a bit of an echo chamber situation because I basically only see stuff I'm already a member of, unless I explicitly go to All or scroll the list of communities.

Are there less involved (lazy) ways of discovering new stuff and broadening my horizons a bit?

Hi all,

How would I go about identifying why all these 400 (and some 499) errors are popping up in my server's logs?

I don't see a way to get Lemmy server to spit out any helpful info. I've tried setting RUST_LOG=verbose in the env, but no luck, still no log output.

No matter which Top sorting method I select in my profile, the result will always be all of my my all-time top posts instead of a selection based on the selected time frame from the drop down menu. All Top (x) selections seem to only show the uncurtailed Top All Time results while sorting by Old, New or Controversial seems to work as intended.

I am browsing the default lemmy website interface from a Firefox web browser.

External images could be linked and displayed using:

• ![](external url)

Then Lemmy images could be resized which I think also shrinks the file size; hence faster display time, save internet data, and save screen space; by adding &thumbnail=:

• ![](https://lemmy. .../pictrs/image/... .webp?format=webp&thumbnail=320)

So, is it possible to do similar but for any external image? Or at least generate thumbnails of many external images? Thanks in advance.

@lemmy_support hello. How long do I need to wait for the e-mail to verify it? waiting 8h now...

Given that instances can disable downvoting altogether, it led me to wondering...

Inb4 "analytics" is a bad word in the fediverse, understandably so, but I ask because for one of the communities that I moderate, I noticed the banner image and icon image were nearly 20 MB each, so I replaced them with smaller versions (<1 MB each). On desktop w/ a fast wired connection, it's no biggie, but it's good practice anyway to minimize page weight, if for no other reason than to make the site more usable for people on slow or cellular connections.

I tried searching for traffic data about Lemmy, and the best I could find is this page on similarweb.com, which shows traffic broken out by country and referrals, among other things, but a breakout of mobile vs desktop appears to be locked behind a paywall.

Do we have any analytics on mobile vs desktop traffic for Lemmy?

Hi, I'm relatively new to Lemmy, but I have been posting a lot in the last few weeks.

One thing I see when I post certain website articles is the above message. The post still works, but it is missing a lot of information that other posts have.

Does someone have a link to documentation of what Lemmy is looking for when it builds a post? I would like to be able to contact the web admins of the problem website, and ask them to modify their code so that it is more "Lemmy-friendly".

Thanks for any help you can send my way.

I'm new to Lemmy and trying to understand how the All feed works. Doing some reading it looks like it is populated by communities that people on the instance I'm apart of have join. Is that correct?

Hello, I wanted to ask what you have to do to be added to the join-lemmy.org page? Is there an email to call? The documentation only reads that you have to meet certain criteria, but is it then added automatically at some point?

I have just started using Lemmy and I love it.

I have had good results sending Lemmy posts to Masto, and vice-versa. One exception has been the above group shown in the title. In Masto, send/receive posts works fine, but the Lemmy version seems cut off from the rest of the Fediverse.

Could someone look into that? Thanks.

Am I doing the lemmy image compression and removal of old proxied images correctly? Here's my docker service for lemmy:

pictrs:

    # this needs to match the pictrs url in lemmy.hjson
    hostname: pictrs
