How "heavy" is self-hosting matrix really?

Hi. I’m kinda of a noob in the world of self-hosting and matrix, for that matter. But I was wondering how heavy is it to host a matrix server?

My understanding how matrix works is each participating server in the room stores the full history and then later some sort of merging happens or something like that.

How is that sustainable? Say in 5 years matrix becomes mainstream and 5 people join my server and each also join 3 different 10k+ people rooms with long histories. So now what I have to account for that or people have to be careful of joining larger rooms when they sign up in a smaller-ish server?

Or do I not understand how Matrix works? Thanks.

Its not “targeted at old school”, its an open, extensible protocol.

If devs focused on extending the protocol instead of building an app to handle things like this, it could do it.

Mucking about with dozens of extensions instead of just installing an app seems pretty old skool, lol, brings me back to bbs life

Digital "bulletin board" for tasks.

$$5051
https://lemmy.ca/u/Hozerkiller posted on Feb 27, 2026 18:21

Hi I’m looking for some recommendations on a digital version of a bulletin board for tasks. We use a bulletin board with sticky notes for tasks that can be described as “busy work,” think stuff like “organize bookcase of old licenses” or “replace thing that is probably gonna break soon so we don’t get a ticket.” More or less stuff we don’t actually care if it gets done so we dont want SLA timers. We have a ticketing system for important tasks but it is unfortunately built in house and is more mean to manage end user workflows rather than IT things and sadly doesn’t have what were looking for without adding tasks to programmers that have a several month long backlog. Our main reason for wanting a digital one is so we can do something like feed in a csv file and make multiple almost identical tasks think “do x in room 1” “do x in room 2” type thing.

If anyone has recommendations it would be massively appreciated.

There are a lot of these and I had no idea what they were even called before posting this. This one looks great thanks.

Everything was .md files on the backend, which was nice. Should make automation simple (but time consuming since you most likley have to create it yourself). The only reason I stopped using it was because I didn’t really need it.

Selfhosted, multiplayer, browser based games

Here are some cool examples I was looking at:

https://github.com/zardoy/minecraft-web-client — Minecraft in your browser, complete with connections to servers.

https://github.com/inolen/quakejs — quake 3 in your browser, has multiplayer as well.

Any other good examples? or good lists?

probably also selfhosted.

Here is a link do selfhosting it: https://github.com/TeamHypersomnia/Hypersomnia/blob/master/README_SERVER.md#docker-setup

How to self-host a Prosody XMPP server on Bazzite with Podman for Movim

$$2474
https://lemmy.world/u/Tattorack posted on Feb 22, 2026 09:59

Just to start off, know that I have zero experience with this. I’m only looking into doing this because I’m absolutely sick and tired of centralised services (in this case Discord) turning to shit, and want to start a Discord-like/alternative federation between my friends.

Prosody seems to be the easiest to set up, and has all the available capabilities for a server that allows Discord-like functionality (text, group voicecall, streaming). Movim is the client that makes use of all that.

But I don’t have a clue how to set up a Prosody server with Podman. I’ve never done this before. I started by downloading the Prosody image through Podman, then tried running it, which prompted the creation of a container. Kept everything at the defaults and tried running it, but it didn’t work.

What do I do from here?

I mean, difficulty is relative mate. I just said I couldn’t get Snikket working (after multiple tries, too) but I’ve spun up both matrix servers. So I’d personally say it’s harder.

I’d be interested in seeing that, or at least knowing which ejabberd container you chose and why.

Old Thin Clients - Which CPU is fine?

$$1701
https://sopuli.xyz/u/theorangeninja posted on Feb 20, 2026 16:47

I am currently looking for Thin Clients on ebay to use as my main server instead of the RPi 4 with an external USB drive.

I found decent offers for: - Dell Optiplex 3020M with i5-4590T 4GB RAM 120GB SSD - Dell Wyse 5070 with Celeron J4105 or Pentium Silver J5005 both with 8GB RAM 64GB SSD

Given the current prices of new hardware my questions are: - Should I go for 8GB RAM? - Or are 4GB RAM fine and I should take double the storage?

Things I want to run on this server: - Karakeep - FreshRSS - Paperless-NGX or Papra - Immich - Booklore

Because I plan to mostly use podman I tried to check for virtualization and all three suppoert Intels VT-x technolgy, will that be fine for my use case?

Advanced Vector Extensions instruction set; introduced with Sandy Bridge in 2011, but not included in Pentium/Celeron branded processors even after then for reasons best known only to Intel.

Mongo is the application that has most irritated me by requiring it, but I doubt it’s the only one.

Correct (which is why I mentioned Kata, as that’s a container runtime backed by microvms, sort of like how AWS uses firecracker to run lambdas and “serverless” container workloads)

For static sites, yes. To actually protect dynamic sites against my butt crawlers, Cloudflare has to do much more than just caching.

And besides that, Cloudflare is a huge single point of failure and highly privacy invasive.

Dynamic sites still get cached.

Cloudflare definitely is a huge single point of failure, and it is a huge problem imo - but what can we do? Their product is so widely used because of how comprehensive, good, and necessary it is.
