@bigtechbreakup @untrusted

Wenn Du Zeit und Lust hast, probiere mal #Quicksy aus. Ist eine supereinfache Einstiegsdroge in #Jabber/#XMPP, ideal für nicht so technik-affine Leute. Ist für Android und iOS, auf dem Desktop kannst Du dann irgendeinen Client nehmen, z.B. #Dino von @dino.

@bigtechbreakup ich bin bei #XMPP gelandet. S.a. https://imday.de/de/

@arcanechat

I voted "no", but not because I'ld dislike the feature. To the contrary, it would be very nice!

Still, I would not switch, because other features, which I use everyday in #Jabber/#XMPP are still missing, e.g. gateways to IRC, Matrix, and SMS. Also: I'm using Jabber since 12 years and convinced most friends and family to use it. Can't migrate them again.

But please go for it! Even as a Jabber fanperson: Everything that makes free and federated chat better, gets my applause!

#XMPP groups are centralized depending on a single server, if server dies the group is gone, server stores group metadata

#Matrix servers store a lot of group metadata across servers

with #DeltaChat the server stores ZERO group metadata/state you don't depend on any server and can easily migrate your profile keeping group state and history in your devices

if Delta Chat had "super groups" with admin/moderation for public rooms, would you switch?

@Peppaplanta

Ich vermute, daß #Jabber/#XMPP in #Syrien funktioniert, insbesondere, wenn man einen Server nimmt, der über Port 443 erreichbar ist. Es funktioniert jedenfalls in einigen Ländern, die ansonsten ziemlich abgeschottet sind.

Vielleicht mal https://quicksy.im/ ausprobieren? Oder noch besser: https://conversations.im/ Beide laufen auf Port 443.

Es braucht #OX in einem sehr wichtigen #XMPP Client, dann könnten wir auch mehr PGPen. :)

@kuketzblog

Sehr schön differenziert dargestellt.

Wer Signal deswegen nicht nutzen möchte, kann mit #DeltaChat auf eigener Mailserver-Architektur arbeiten. Aber #Signal kann wesentlich mehr als DeltaChat.

Oder #Conversations auf #XMPP Architektur. Dort ist aber die Handhabung von Schlüsseln schlecht gemacht, führt ggf. zu einer Inflation von Schlüsselpaaren.

Daher bleiben wir bei Signal, wobei wir DeltaChat als Fallback haben.

@kris

Using Thunderbird for #Jabber is what I call a #BadIdea™ nowadays 🙂

Please try a modern client, e.g. #Gajim by @gajim, #Dino by @dino, #Conversations_im by @daniel, or #Monal by @Monal.

Note, that I have most of my non-technical friends and family on #XMPP, and it works pretty well.

I did a new try with #xmpp it was worst than expected.

I remember xmpp or jabber was an instant message system that works well.

I accepted a new test in the hope that I could accept it and why not use it.

But it simple does not work. I understand now why nobody use it exept geek people who like to dive in the cryptography or like command like. xmpp is not a tool for every body

At work I have to solve every day problem I don't want to do the same at home I want something I click and it works

My client was #thunderbird

If the client know that my client is OMEMIO encrypted why not sending it normale and readable ?

Nach einem Ejabberd-Update und -Neustart haben die Familienmitglieder nun teilweise Probleme mit der OMEMO-Verschlüsselung.

Jetzt debugge das mal halbwegs mit lauter nicht-Technikern, die einfach nur ihre Ruhe und einen funktionierenden Familienchat haben wollen und zig bis hunderte Kilometer voneinander entfernt leben.

Hasse gerade alles.

Wieso muss mit jedem Ejabberd Neustart irgendwas kaputt sein? Meistens sind es nur S2S Verbindungen, die sich mit weiteren Neustarts wieder einrenken. Aber diesmal ist es echt ein Problem.

Habe _echt_ keine Zeit für sowas :(

Gotta love how there’s a single nice, modern XMPP client for desktop and its encryption scheme is incompatible with every other XMPP client. Nice things just weren’t meant to be had, were they?

@ErikDerBezwinger @maexchen1

Ich bin sehr für "dezentrale Lösungen, die alle miteinander reden können."

Das ist mit freien, dezentralen Technologien, wie IRC, #Jabber/#XMPP, Matrix usw. möglich bzw. implementiert, als bridges oder gateways.

Mit Signal und Threema sehe ich wenig Chancen. Es geht nur als "puppetering gateway", was #slidge z.B. für Jabber mit Signal macht. Nichts gegen Signal oder Threema, aber man sollte es nicht #digitaleSouveränität nennen.

You like Signal for it's outstanding #confidentiality? Fine!

You like Threema, since it's safe, it's from #Switzerland, and #ElsbethSigmund as #Heidi was your #childhoodCrush? Great!

You like Whatsapp, because your friends are there? I don't blame you!

But 𝐩𝐥𝐞𝐚𝐬𝐞 don't claim, that any of those #centralServices would support #digitalAutonomy, #digitalIndependence, #digitalSovereignty. They have their merits, but they still are #walledGardens.

@ianthetechie

I don't have any experience with #selfHosting Matrix. From what I heard, it can be difficult, if users join huge rooms. But it should be just fine, if not.

I do #selfHost some #Jabber/#XMPP servers, though, both #ejabberd by @ejabberd and #prosody by @prosodyim and that's pretty easy.

From what I heard #snikket by @snikket_im, a dockerized prosody, is even more easy, but never tried it.

Maybe give both Matrix and Jabber a try and report here on your experience? I'm curious!

@ianthetechie @ben

ATM, pidgin and adium cannot be recommended, because they are outdated regarding current #Jabber/#XMPP usage and standards, but there is work going on to solve that.
