Matrix

Hey Lemmy!

Exactly as the title says.

I'm a user, not a server admin, so this is about deleting messages I've sent rather than cleaning old messages on a server. Ideally I'm looking for a script which I can run on a timer once a day, and each time it runs, it will delete all my messages, or my messages in some specified rooms, that are older than say two weeks. Basically an automated finger that presses the delete button repeatedly.

I know about m.room.retention but I don't want to have to set it for every room. And it doesn't seem to be reliable; it doesn't work in a matrix.org test room I set up with one minute retention. Even when I cleared the cache.

The closest I've found is this branch, but as this issue mentioned, it purges all messages rather than only messages older than X time.

If no one has a better script, I'll write one myself or fork the above script. But in case anyone here's already gone to the trouble... I won't have to learn the Matrix API :)

Edit 1:

I did make the script, but it's slow; each message deletion sent to matrix.org has to wait about 4 seconds due to rate limiting. I send a lot of messages per day, so it's barely an acceptable solution.

The whole concept also feels awkwardly inefficient because I have to send a request for each message, rather than the server and clients running their own timers.

I moved to Delta Chat for now, for its disappearing messages.

I found some nice comparison tables of instant messaging services that could be of use:

• https://en.m.wikipedia.org/wiki/Comparison_of_cross-platform_instant_messaging_clients
• https://www.securemessagingapps.com/
• https://eylenburg.github.io/im_comparison.htm

I set up a Cinny instance. If I link users directly to the Cinny instance it prompts them to create an account on my Matrix server but then they have to manually search for the space to join. If I grab the link directly to my space from Cinny, it links to matrix.to as an intermediary, which will prompt them to sign up with the matrix.org instance, which I DO NOT WANT. Is there no way to send an invite directly from/to my Cinny instance/space? You can only send invites via matrix.to?

id like to just hang out. like on mumble. but I'm using matrix now... anyone know of an active room or willing to join one?

Hi, folks! I've already create my own server for Matrix, and now I'm trying to set up Cinny for anyone can use my server from a browser.

But Cinny writes me:

Failed to connect. Homeserver configuration found with my homeserver name appears unusable.

When I'm trying to choose my server from a list.

Here's the config file of Cinny:

{
  "defaultHomeserver": 2,
  "homeserverList": [
    "my.server.org",
    "matrix.org"
  ],
  "allowCustomHomeservers": true,

  "featuredCommunities": {
    "openAsDefault": false,
    "spaces": [
      "#cinny-space:matrix.org",
      "#community:matrix.org"
    ],
    "rooms": [
      "#cinny:matrix.org"
    ],
    "servers": ["my.server.org", "matrix.org"]
  },

  "hashRouter": {
    "enabled": true,
    "basename": "/"
  }
}

But when I'm trying to use Cinny from it website - everything works fine. But when I'm trying to use this from my self-hosted variant - I gets this error.

So, what do I do wrong, people? 🤔

For a while, I was running a conduwuit server. Conduwuit has been abandoned, and I wanted to migrate my server to upstream Conduit.

Has anyone done this before? I'm using Docker Compose for Conduwuit.

tried searching but came up short... anyone know what's their message retention policy i.e. how long is chat history available for private, 1on1 chats?

Reminder to all Homeserver admins!

More info can be found in the TWIM post from this week(as well as last week): https://matrix.org/blog/2025/03/21/this-week-in-matrix-2025-03-21/

Personally, I've successfully setup the backend and frontend for my own HS which works great, meaning we're fully independent from the Matrix.org server. Documentation for the process is much improved compared to a few months ago.

Signal has a "Note to Self" option which basically lets you send texts to yourself for reminders, etc. Is there a way to do this with any of the various Matrix clients, and if so how?

New Matrix user, eager to dive in. What is your preferred method/website for finding interesting servers and rooms?

I am facing a really weird issue with Element Call on my Matrix Dendrite server. It seems that only the person initiating the call can unmute and use videochat. The recipient of the call cannot talk even when unmuted or show video when enabled.

Nothing in the Dendrite container logs shows anything out of the oridinary.

I am using a machine that is running Ubuntu 20.04 with Docker and CasaoOS. I use Cloudflare Tunnels for my Matrix server. The client devices are both Google Pixel 8s running GrapheneOS. All of the proper settings for the app should be enabled (unrestricted battery).

Here is a picture of what the recipient of the call's video looks like to the person who initialized the call again no audio is present from the recipient either.

On very rare occasions have I gotten audio and video to work for both memebers of the call. It is very inconsistent. I am curious if this issue is in anyway related to the push notification issue I am also having.

Thank you so much for your help and time!

I was able to finally get sliding sync up and running with my dendrite server!

Element X and Schildichat next allow me to sign in with no "this server does not support sliding sync" error.

However these clients do not show my chats or rooms. If I try to create a room it will work but if I bavk out it will show a blank chat page.

If I go to the regular element client I can see the newly created chats from element x/schildi.

Any help would be appreciated!

Edit: sliding sync now works it was an error in my compose file for the url! I needed it to be set to my matrix url and not my sliding sync url.

I am hosting a Dendrite homeserver. However, I'm not happy with the pace of development of the software and I'd like to switch to Synapse.
Is there a documented way to migrate the data (rooms, chat history, users) from Dendrite to Synapse? I've used matrix-docker-ansible-deploy to set it up.

I'm currently trying to set up my own matrix instance, and most of it is working, except for the federation. Due to technical reasons the only way to host anything is over Cloudflared. I know it's not perfect but it is what it is. So now here's my problem. I'm currently trying to get federation working, but I'm a bit confused about the documentation. Also, I'm using the apt version, so for some reason most of the Directories are also different... If anyone did this before and could help me with this, i would be really thankful.

firstly happy new year for all.

I need to start use Matrix to talk with my biggest friends and colleagues of my university, but i read is good not create an account on matrix.org and create an account in others public servers , to not centralize the matrix protocol. My question is if anyone has a good experience with others public servers, besides matrix.org. Any tip or advice?

I found this servers on joinmatrix with longstanding: https://tchncs.de/en/matrix | https://syscom.utwente.io/info/matrix/homeserver/ | https://matrix-help.envs.net/ | https://tedomum.net/service/matrix/ | https://rollenspiel.chat/ ...

Which one should i choose, any tip?
