Last of the Matrix series at the Decentralisation Communication devroom: what does it take to bring MLS to decentralised environments? Hubert tells us so!
Very nice talks at the #Decentralised #Communication room in @fosdem involving @matrix, and @EPFL is on the map! Join us at matrix.epfl.ch

I didn’t get a chance to ask the question during the panel, so I’ll ask it out-loud here :)
I tend to have a mental model of behaviour that I think about on social media: interaction level and collective level.
If you want to moderate interaction level content, then that’s things like “is this image problematic” or “is this person harassing someone else” and so on. That seems to be what the DSA mostly addresses? Which is great! We need more protection there
But the collective level is something I’m curious about: what happens when attacks are designed to be “harmless” or “not violating” at the interaction-level, yet deeply harmful at the collective level? How does one defend against a synthetic threat carefully designed to target a vulnerable collective in a way that no interaction level defense is really capable of handeling?
Do we have regulations around this yet? Is it a problem we’re trying to address at the governance level? (I know the tooling is nearly non existent, but slowly starting to emerge. It would be encouraging to see similar momentum in governance)

How hard can it be to develop a good software stack when you give it away for free?
Neil covers how Element has been faring and what the future holds to keep the world open and decentralised
#XMPP Community
XMPP is listed at the ‘Digital Independence Day’ (DIDAY) as an alternative chat option and the community created switch recipes to enable users to migrate to independent messaging.

The German initiative ‘Digital Independence Day’ (DI.DAY) has been kicked off this year to enable users to migrate to open-source software alternatives in various contexts. Beside others XMPP is listed as an alternative chat option and …xmpp.org
What if we used Decentralised Communication backends for more than instant messaging and calls?
Robin, Timo and Valère walk us through how they hooked a Godot game into a Matrix widget
Currently in the Decentralised Communication devroom: Florian and Dave telling us about their plans to make @element Web lighter and faster
Don't forget to visit the @xmpp booth and to attend the "Decentralized Communication" talks tomorrow:

Now in the Decentralised Communication devroom: @cassidy and Anne presenting how Roost helps orgs mutualise their Trust & Safety efforts to keep people safe
I caught the last few minutes of your speech.
This is one of the best communities connecting disabled users and software/hardware engineers
Currently in the devroom: Travis giving us on update on Trust & Safety in Matrix, and policyserver
Come by, meet XMPP enthusiasts and grab some merch at the XMPP #Realtime Lounge!

To understand how we can replace Google push notifications (FCM) with something open source and decentralized, we need to understand how they work and why they are needed in the first place. This talk explains the mechanics of push notifications and why, despite their potentially bad reputation, they are a more elegant solution than having every app maintain its own persistent server connection.
While open-source tools like microG can remove proprietary Google software from your Android phone, the actual notifications are still sent via Google's servers (Firebase Cloud Messaging).
UnifiedPush is a framework that allows push notifications to be delivered in a decentralized manner or through self-hosted servers. Numerous open-source Android apps already support UnifiedPush, including Tusky, Ltt.rs, Fedilab, DAVx⁵, Fennec, Element, and many more.
The presentation ends with a short demo on how to use UnifiedPush on Android.

I proposed an approach where #FOSDEM can provide better support for #accessibility

I will try to demo it in my session later today, but speech to text isn't that hard to add in these days. We should be encouraging text transcripts.
We should explore adopting or integrating the MidCamp Live Captioning project as part of FOSDEM’s accessibility efforts. https://github.com/MidCamp/live-captioning?tab=readme-ov-file#live-captionin...mgifford (GitHub)
I would like the @fosdem community to embrace #accessibility
In effort of that goal I've started by recording some problems and possible solutions for the website:

This is a lot of work that together, as a community, we need to address. #FOSDEM needs to be more inclusive for people with disabilities.
25% of the population has disabilities & the are part of our community.
25% of the population has a disability. 100% of the population has temporary or situational barriers which needlessly stop them from accessing information on the web. The FOSDEM community isn't doi...mgifford (GitHub)
A very nice first day at FOSDEM. I spent time at the @matrix booth and met overwhelmingly enthusiastic people, then left it to our fabulous team of volunteers.
I’ve met Allan and @jsparber at the @gnome booth, got one of those fabulous systemd T-shirts, said hi to the @postmarketOS gang, got a T-shirt and brainstormed with @pabloyoyoista, got to thank Proxmox and OpenTofu for the great tools they provide.
#FOSDEM is where internet friends materialize.
