  only admins can set communities to hidden currently. this is also not exposed via lemmy-ui, it has to be done via API.

• ⁨Comment⁩ on ⁨[sh.it.post] We're #5! We're #5!⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  based on the creation date advertised by the instance, lemmy.ml exists since 2019-04-20. lemmy.world exists since 2023-06-01.

• ⁨Comment⁩ on ⁨are we federating with dot world? how to check federation status?⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  fwiw, the estimate number only states the max amount of activities behind. the real number can be lower, but not higher (unless sending is entirely broken on the instance being checked).

  each activity being sent has a numeric id in the database. lemmy has an api that returns the id of the last activity that was either successfully sent to an instance or skipped when it didn’t need to get sent (e.g. pm to a user on a different instance). there may also be holes in activity ids due to postgres implementation details for auto-incrementing sequence ids.

  for determining the highest known activity id to compare it with the last activity id sent to a specific instance, you can just go through the successfully sent ids for all instances in the response and find the highest number across them all. then you can calculate the difference between the highest number and the number for the specific instance.

  depending on the lemmy version and timing of the action, it can take up to 30 seconds for the activity queue to deal with new activities, so on a somewhat busy instance the delta is likely rarely going to be zero.

• ⁨Comment⁩ on ⁨Seems .world and .ee federation are broken⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  it’s not just lemmy.world.

  of the larger instances, the following have trouble sending activities to lemm.ee currently:

  • lemmynsfw.com -> lemm.ee: 2.81d behind
  • sh.itjust.works -> lemm.ee: 1.04d behind
  • lemmy.world -> lemm.ee: 22.5h behind

  i pinged @sunaurus@lemm.ee on matrix about 30h ago already about the issues with federation from lemmynsfw.com, as it was the first one i noticed, but I haven’t heard back yet.

• ⁨Comment⁩ on ⁨Defederation issues between Lemm.ee and Lemmy.ml⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  this doesn’t just affect lemmy.ml.

  it seems that lemmy.ml -> lemm.ee was somehow fixed yesterday, but there are several other instances that also have issues sending to lemm.ee:

  • hexbear.net: was broken since 2024-10-23, fixed since 2024-10-25
  • lemmy.blahaj.zone: broken since 2024-10-24
  • lemmy.ml: was broken since 2024-11-01, seems fixed since 2024-11-16
  • startrek.website: broken since 2024-11-15
• ⁨Comment⁩ on ⁨Is it possible to get back a username of the account I deleted?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  this is the important part.

  when an account is deleted the associated private key used for signing activities is deleted as well. the activitypub protocol does not really define how software is supposed to deal with deleted and recreated actors (which includes users), so some software has been built with the assumption that any change of encryption keys for a user means it’s an invalid signature and will prevent activities involving that user to federate to that software.

• ⁨Comment⁩ on ⁨Defederation issues between Lemm.ee and Lemmy.ml⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  this seems more of a federation issue than a defederation issue ;)

• ⁨Comment⁩ on ⁨Feedback about our name: someone's concerns on sharing⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:

  I think most (especially mobile) clients simply don’t have this option and will always copy/share the “fedi link” - the url where the content is canonically hosted. all other URLs are simply cached representations of the original content.
