quick heads up. Our impressions: #matrix is going strong with public sector entities, and it's where most dynamics happened at the conf.
We are rather focused on private and resilient messaging where servers don't play a big role; as we want #chatmail relays to be dirt cheap to operate, no pro version needed. Our focus is on informal usage, groups, family, friends, affinity or interest groups, whereas matrix is increasingly focusing on corporate/ organizational use cases. YMMV
☁️The recent AWS outage showed how fragile “cloud-based security” can be.
When one datacenter faltered, global communication tools — including Signal — went dark 🌑
🕸️Matrix-based messaging systems kept running because they don’t rely on a single provider.
Resilience = decentralization
Let's invest in open, federated platforms.

Hey, did you know that Movim allows you to link your #Discord, #Telegram, #WhatsApp and #Matrix accounts to your main XMPP one and chat with all your contacts in one integrated platform? 🤩
We are working hard with @nicoco to ensure a perfect integration with the Slidge gateways project slidge.im/ 🥸🤝🥸
Message synchronization, reactions, stickers, GIFs, chatrooms, invitations, file transfer... you can now find all those exciting features fully working across all your linked accounts in Movim ✨.
Now you can move to #XMPP while staying in contact with all your friends. 👌
Try it out on mov.im/ or by deploying your own instance 😸!
Venue clean, all remaining items packed. Good-bye Kaleidoscoop, thanks a lot to all volunteers, the @matrix foundation, our sponsors, our speakers and my friends @thibaultamartin and @HarHarLinks for rocking the #MatrixConf2025.
Se y'all on #39c3 !
Important message from my talk!
Exclude Insecure Devices is coming!
After April 2026 (or maybe even sooner), if your Matrix device is unverified, you will not be able to talk to someone who is using Element!
Or any other client complying with MSC4153
@TheDailyBurble, happy to help.
Another cool feature of #XMPP are "gateways" that make it relatively easy to connect with other IMs.
e.g.
#Libervia to #ActivityPub and #email (CC @Goffi )
nlnet.nl/project/Libervia
libervia.org
#Slidge to all sorts of other IM like #Matrix, #Mattermost, #Steam, #Discord, #Whatsapp, FB … (CC @nicoco )
Slidge is a chat gateway library for XMPP built in Python, and a set of gateways for other networks.slidge.im
Not related to the outage, really, this morning I found myself searching for federated IM protocols, ideally end-to-end encrypted. I know we have @matrix but was looking for something more DM-oriented like Signal, but federated.
Looked into XMPP, but E2E encryption relies on add-ons. It seems the closest we have to that is actually #Matrix.

Exhausted, happy and looking forwards for next year's conference.
Time to travel home. Thank you all for attending and making the #MatrixConf2025 possible. It was an honor to organize this conference for you !

We had an amazing after show gathering with the activists from @hackstub after a successful last evening of the #MatrixConf2025. It was an interesting exchange, we learned a lot about your work and it was super pleasant to network with other hackers sharing our vision and values we bear as the ecosystem.
Now time to catch some sleep before rocking the last conference day.
Good night & see you tomorrow !
After fixing some issues, migrating my #matrix media off #matrix-media-repo and onto #synapse was surpisingly straightforward.
I've written a short step-by-step list on what to do and put it here for now:

My talks at #MatrixConf2025 are tomorrow 14:00 CET and 16:00 CET. I am talking about our progress on "Invisible Crypto" and agreeing a shared terminology to talk about Matrix encryption. Watch live at conference.matrix.org/watch/ . Recordings will be available later too.

Special thanks to the Matrix.org Foundation @matrix for developing the #Matrix protocol and @element for the Element software suite!

La Contre-Voie lance un nouveau service de messagerie instantanée, qui incorpore également une plateforme de visioconférence ! 🎉
Basé sur le logiciel Element, développé par la fondation #Matrix, ce service constitue une alternative à Microsoft Teams ou Slack ✨

Beeindruckend finde ich den lebendigen und vielfältigen Austausch in den #Matrix Räumen von @librechurch@kirche.social auf synod.im
Von Fragen und Ideen zu digital souveränen Tools, die auf dem Marktplatz diskutiert werden bis zu Erfahrungen und Herausforderungen immer kleiner werdender christlicher Gemeinden im Raum Glauben teilen.
Anyone using #Tammy as a #Matrix messenger client?
What do you think about it? Why do you use it? How much do you use it? On which device type is it installed? What features do you miss?
You're invited to talk on Matrix. If you don't already have a client this link will help you pick one, and join the conversation. If you already have one, this link will help you join the conversationmatrix.to
I would not underestimate the value of having a go-to home server free of charge for people new to #matrix. In the end, it is the members of the foundation to decide whether they agree with the use of the budget they contribute. Are you also a member?

Regarding the more general accusation on #Matrix being just another VC-backed one-company-product, I'd like to refer to another recent post from the foundation, and only quote from its final paragraph:
> … triggered some defensive reaction with other European players in the market. It is a shame that small European players feel the need to fight one another rather than collaborate via open source software against the bigger non-European and proprietary players.

Matrix, the open protocol for secure decentralised communicationsRobin Riley (matrix.org)
The Matrix Foundation now has some volunteer working groups, and a formal process for creating new ones;
matrix.org/foundation/working-…
For example, there's a WG for documenting moderation issues; reducing spam, easier handling of trolls, griefers and grifters.
If you're keen to get involved in keeping the Matrix protocol network fully decentralised, surveillance-free, and non-corporate, this could be a good way.
@matrix Is there a place the Matrix community can discuss protocol-level issues that isn't GritHub? If not, it really is about time to set one up. Lemmy and PieFed are options for an official threadiverse instance, and both Discourse and NodeBB now have some level of ActivityPub support.
This could even be an opportunity to dogfood adding Matrix protocol support to a forum package.
#TIL that Mattermost is now offering its own bridge to Matrix, which depends on a Synapse instance running alongside the MM server;
mattermost.com/marketplace/mat…
This is what RocketChat were doing since about 2022. Although their documentation suggests they are working on full Matrix support inside the RC server itself, due sometime this month;
Woah! Only now did we discover a great blog post from @wq who discusses the progression from hosting a #Matrix , a #Snikket and a #SimpleX server, to now running a #chatmail relay runtimeterror.dev/self-hosted-…
It's an excellent read, with lots of good advise, including having a public "hello" profile and another unpublished chat profile for private chatting. #deltachat apps have pervasive multi-profile support (and multi-device support) so it's pretty easy to establish such a two-profile setup.
Shit happens! No one should be judged.
But, can one do better?
Maybe there could be a better user guiding for new registrations in #Matrix #Apps (#Element, #ElementX) to give a better choise for #Homeservers instead to lead people always to matrix.org.

Everyone is now realizing that WhatsApp is evolving towards its latest form (archive.md/L3W74). If you value secure messaging, you may want to check out @signalapp or @matrix (wich is #federated). EPFL also has its own Matrix instance at matrix.epfl.ch (use @element as a client).

Well fuck. If a room in #Matrix is on Homeserver A, and an admin on Homeserver B runs /upgraderoom, then the room is moved to Homeserver B. It does not stay on Homeserver A.
I uhh... do not want the unofficial Slackware matrix server on my homeserver.
Edit: omfg sidegrading it does not move it back
EDIT EDIT: FINALLY
