You should know:
If you write a private post to someone else on #Mastodon, and you mention another user by their @, that user is added to the conversation and can see that post too!
For example, if you report someone harassing you to an administrator via private mention message, and you tag their account, they can see that!
Never treat private posts on Mastodon like a messenger!
Use actual chat software like #Matrix, #XMPP or #Signal for talking one-on-one, please.
Irmi Wutscher hat sich für #Matrix auf Ö1 bereits bestehende Alternativen zu den großen Plattformen mit dem Netzpolitik-Journalisten @markusreuter und dem Wissenschaftler @leonido angeschaut.
Mit deutlicher Kritik an #Bluesky und welche Vorteile dezentrale föderierte Netzwerke mit vielen Instanzen, wie das #Fediverse bieten. Und weshalb Hashtags wichtig sind für die langfristige Nutzung.
Ausserdem: die Forderungen von #Savesocial & die #Mastodon Instanz @uniinnsbruck
Matrix, criticism of criticism, negative
I'm fine with the criticism of #Matrix on Fediverse, I do that sometimes myself in private rooms or sometimes blog posts, but holy shit, I wish that criticism didn't have as much toxicity and misinformation in it as it currently have.
On one hand there are Matrix fans who unconditionally scream how great Matrix is and can solve all world problems, and on the other there are nostalgia gremlins praising IRC over high heavens as an alternative to commercial platforms like Discord for literally everyone because Matrix is "literally unusable" or something.
Both groups are delusional IMO.
Ich hab jetzt nen #Matrix-Account und habe vor, ihn einzusetzen. Gibts da irgendwie Communitys, wo sich die nerdig linksgrün-versiffte Bubble trifft? 
Having stopped using Fractal this week, and now having a #Matrix @element web tab open at all times in Firefox, appears to be quite problematic for laptop CPU temperatures and power consumption (on Linux, with Wayland).
My global system monitor (and about:performance in Firefox) tells me that the Element web client constantly eats 10-15% of one CPU vCore even when Element's tab is not focused, thus keeps waking the CPU, leading to high temperatures and crappy battery life 
ElementX is *so* much faster than the current stable versions of Element and its various soft forks (I'm currently using SchildiChat).
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.
Okay, what's the best #Discord alternative for a #chat platform, I want one for my #streamer / #vtuber community, currently using Discord but want to Own It and such. For real this time.
Is #element / #matrix still the biggest one? I guess there's #IRC, I want whatever I can get the largest non-zero number of people using. And voice chat ideally, video not necessary.
tech complainy
Who do I have to bribe to build a "mentions" menu into a #Matrix client? How is this still not a thing? Both Nheko and Element have issues for it from like 2 years ago.
Sabato 5 aprile parlerò ad una riunione didattica con il #NaLUG riguardo le piattaforme di #chat libere e #opensource, decentralizzate e private. Maggiori informazioni qui sulla riunione e su dove si terrà: https://www.nalug.tech/nalugunina-sabato-5-aprile-2025/.
and they lived happily ever after
(tranne l'agente smith che continuava ad agentesmittare in ogni momento)
@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 https://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: https://crypto.stackexchange.com/questions/9268/is-asynchronous-perfect-forward-secrecy-possible).
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.
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?
