Strypey<p>ElementX is *so* much faster than the current stable versions of Element and its various soft forks (I'm currently using SchildiChat).</p><p>As I've said before, I'm guessing it will take another 6-12 months for all the Matrix 2.0 upgrades to be rolled out and fully stabilized in the various app and server software. But if ElementX performance is anything to go by, the new and improved Matrix ecosystem will be well worth an open-minded test.</p><p><a href="https://mastodon.nzoss.nz/tags/Matrix" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Matrix</span></a> <a href="https://mastodon.nzoss.nz/tags/Matrix2" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Matrix2</span></a> <a href="https://mastodon.nzoss.nz/tags/Element" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Element</span></a> <a href="https://mastodon.nzoss.nz/tags/ElementX" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ElementX</span></a> <a href="https://mastodon.nzoss.nz/tags/SchildiChat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SchildiChat</span></a></p>

Markus Göllnitz<p>I've always had a small list of features I've deemed important for easing switching to Matrix (e.g. third-party identifier resolution like finding contacts by phone number).

@Xeniax Totally nerdsniped :D I'd love to be a part of the study.

I don't think that #KeyServers are dead. I think they evolved into Verifying Key Servers (VKS), like the one run by a few folks from the OpenPGP ecosystem at keys.openpgp.org/about . More generally, I believe that #PGP / #GPG / #OpenPGP retains important use-cases where accountability is prioritized, as contrasted with ecosystems (like #Matrix, #SignalMessenger) where deniability (and Perfect Forward Secrecy generally) is prioritized. Further, PGP can still serve to bootstrap those other ecosystems by way of signature notations (see the #KeyOxide project).

Ultimately, the needs of asynchronous and synchronous cryptographic systems are, at certain design points, mutually exclusive (in my amateur estimation, anyway). I don't think that implies that email encryption is somehow a dead-end or pointless. Email merely, by virtue of being an asynchronous protocol, cannot meaningfully offer PFS (or can it? Some smart people over at crypto.stackexchange.com seem to think there might be papers floating around that can get at it: crypto.stackexchange.com/quest).

To me, the killer feature of PGP is actually not encryption per se. It's certification, signatures, and authentication/authorization. I'm more concerned with "so-and-so definitely said/attested to this" than "i need to keep what so-and-so said strictly private/confidential forever and ever." What smaller countries like Croatia have done with #PKI leaves me green with envy.

@quinta ho sentito il tuo intervento a 2024. Sull'uso in azienda di #Nextcloud e #matrix: in ditta abbiamo provato NC, ma stiamo passando a MS😩 a causa delle problematiche di NC. Diverse app sono di qualità alpha e non sono a conoscenza di un provider che ti gestisca il servizio, curandosi di tenerlo up. Sei tu che devi accorgerti di problemi e aprire ticket. Qui sta la grande differenza con i colossi cloud. Anche la collaborazione va in crisi con tot persone, corruzione di dati.

It feels good in the curent situation to be fully free of any proprietary solution.

#Linux #Debian #FreeBSD on all systems only, own #public #DNS servers on own systems including management.

#Mastodon, #Matrix , #Bridges , #Email , #SOGo #Nextcloud #Owncloud #UnifiedPush #ntfy #HomeAssistant #WebSites mostly done with #Hugo, and far more all self hosted on own systems in the basement or in our housing rack.

I said it before on Mastodon. I'm reposting this again. Comparing #DeltaChat and #Matrix together, if you want hassle free and consistent messenger for private #E2EE chats, don't go for Matrix. DeltaChat is way better.

However, if you want something like a public forum, or a public chatroom, don't go for DeltaChat. Matrix is way better suited for that. And DeltaChat does not support public groups at all. In DeltaChat groups, there is no admin or moderator and everyone have got permission to remove or add the others.

I think I have to write a longer post on my personal blog about these two, comparing them together.

PS: Another Matrix encryption bug few minutes ago triggered repost of this.

Okay, so here's a #matrix / #synapse question that I am far too tired to find the answer to:

If i have more than one user on my server, and they both go to a room, do I store duplicates of t hat room, one for each user? Or is it stored on my homeserver in such a way that both can grab it and decrypt it?
