  • There’s a page explaining it in more detail, but basically, all servers need to verify the complete chain of state events in order to trust data and messages about the room. This is because otherwise malicious servers could make bogus state events and messages that are not valid, like scam messages and unauthorized room setting changes.

    In matrix, when you create a new room, or edit room settings, a state event is made. The same is true for changes in user permissions like who is admin, and for settings related to who can join the room.

    The last one is key, because this means that in order for servers to trust other servers’ messages, they need to verify if the user that sent the message joined the room in a legit way.

    In order to do this, when a user joins a room it must cause a state event. However, this makes it easy for people to abuse, by joining a room with a ton of accounts, it spams state events to all connected servers, which bogs them all down because they are required to process all state events in order for chain of trust to function.

    Even for rooms with non-malicious usage, servers can still be bogged down if the room is very big, which might be what happened with you or your friend joining a big public room.

    Basically, in my opinion, Matrix cannot be used with public rooms as it stands today.



  • Using an old Netgear Readynas R102 with 4.5 TB of usable storage in RAID 0.

    I used to run all kinds of services on the nas itself via the ssh access, but I’ve since moved those to separate raspberry pis. The pis use the nas as a networked storage.

    I run a webserver, music server, matrix server and torrent client seeding ubuntu images.

    I want to make a storage cluster using Ceph in the future, but I’ve not found any suitable small computers that I could use with that.
