  Movim - Decentralized social platform

  

Hi! Glad to see XMPP on the HN first page this morning :)

I'm working on a social-network and IM web platform (for 12 years already!), fully built on XMPP https://movim.eu/.

Thanks to its extensibility and the PubSub XMPP standard you can easily build social-network like features. The standard is pretty simple, it's Atom 1.0 transport within PubSub.

For those that likes RSS/Atom you can also easily publish Atom newsfeed to PubSub (see https://github.com/edhelas/atomtopubsub) and follow your favorite website using your XMPP account and with real-time pushed articles. Here is ArsTechnica as an example https://mov.im/?node/news.movim.eu/ArsTechnica

XMPP is not only for IM, but way more than that ;)

  Open-source XMPP client for Android

  

Depending on when you last tried xmpp you might have experienced the OTR hell, which was never really codified 100% and spawned subtle incompatibilities between clients leading to weird and nondescript errors that never got addressed. Nowadays the popular clients support omemo (https://conversations.im/omemo/), which makes encryption just work™ out of the box and without hassle. The only exception to this is xabber, who are apparently afraid of law enforcement destroying their lifes should they implement proper encryption and also feel no need to support it anyways: https://github.com/redsolution/xabber-android/issues/540

  XEP-0384: OMEMO Encryption for libpurple.

the omemo support in pidgin is just through a plugin, as with many recent XEPs. i think people tend to forget that pidgin's focus is being a multi-protocol messenger. it ships with XMPP support, but that mostly includes the base.

i wrote that omemo plugin and tbh I am pretty burned out. so many moving parts, it's hell to debug and i'm not even sure where to go next with it. (plus people keep talking badly about pidgin anyway and i am not sure if it's even worth continuing.) i am very thankful for all the contributions so far, especially the help with packaging it. sorry if someone feels let down.

i feel like this is the right moment to ask: if anyone reading has an idea how to improve the state of things, i'd be happy about some suggestions. the project page is https://github.com/gkdr/lurch

Yes, Quicky from the Conversations developer who bragged about copying main features of WhatsApp and Signal.

Another one is Kontalk, https://www.kontalk.org/.

Both XMPP clients require a phone number, and both present the phone number as a benefit in comparison with other XMPP clients without this requirement.

  Using cheap LoRa wireless modules to chat over long distances.

> then try to find your contacts again (which may be cached by your client or not)

You can save XMPP account IDs in any mobile address book.

> Finally, you have to convince "someone" that this is just you with another account on another server. There is also no verified E2EE anymore.

I'd pretty much just do a video call at that point.

> How is this different from "when Signal goes down one uses a completely different instant messaging system", apart from using another client?

You don't have to use another client software.

> Which means: If one of these hosting companies blocks XMPP traffic (e.g., if a rogue state starts censoring) or one of these XMPP servers goes down, a huge part of XMPP users is affected.

Equally applies to most messaging apps out there. Some XMPP apps have the benefit of also supporting using Tor and hidden services - Signal/WhatsApp/etc, don't.

Don't want to use the Internet at all? You can even go wild and do something like: https://github.com/ddamianus/Lora-Chat-Device - I realize this is something most people would not do, but XMPP's _flexibility_ allows this to be an option if it was something people wanted. Can't do Signal over LoRa.
