@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.

@ben @ianthetechie

I'm mainly using #Gajim by @gajim on #Debian desktop and #Dino by @dino on my #Mobian smartphone.

I don't run Android or iOS, but friends use #Conversations_im by @daniel on the former and #Monal by @Monal on the latter. Or their respective #Quicksy flavours, which are slightly easier to onboard for less tech-savvy people.

#Jabber

#XMPP Summit

Being an unconference, every participant will raise agenda points and then those will be prioritized by interest. The first topic is "XMPP 2.0".

@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!

Totgesagt? Keineswegs. Rund um Jabber (XMPP) gibt es nach wie vor eine erstaunlich engagierte Community. Der Digital Independence Day hat ordentlich Bewegung reingebracht: Innerhalb nur einer Woche entstanden Info-Folder in drei Sprachen – komplett layoutet von @digitalcourage. Deutsch und Englisch wurden noch rechtzeitig zur FOSDEM gedruckt, Französisch folgte als PDF. Ja, ein paar kleine Fehler sind noch drin – Version 2 kommt asap. Die Folder gibt’s im Digitalcourage-Shop: https://shop.digitalcourage.de

Mehrere gedruckte Faltblätter und Karten zum Thema **XMPP/Jabber** liegen aufgefächert in einer Schachtel. Überschriften wie „Wechselrezept XMPP-Messenger“, „Recipe for XMPP Messaging“ und „Enjoy Your Meal!“; farbiges Design (Gelb/Lila), Icons, kurze Erklärtexte und ein QR-Code.

The only relevant feature for any instant messaging app (or social app, for that matter) is: Are my friends using it? People will gladly overlook minor inconsistencies or missing features as long as they can communicate with their friends. We shouldn’t recommend #Signal as a stepping stone before Jabber/XMPP becomes "good enough," if goodness is defined by the number of people using it.

#Jabber #XMPP #Conversations_im

Aaaand it’s released! 🥳

Ejabberd 26.01 ships a new module `mod_invites` that lets you create invites to either make it easier for others to add you to their contact list or create new accounts. Or both!

Chatten geht auch ohne Werbung und auch ohne marktübliches Smartphone 😉 Ein Beispiel ist #XMPP / #Jabber - ein Internetstandard für Instant Messaging.
