Eigtl. wollte ich nur einen kleinen Text auf einer "versteckten" Unterseite um sie auf einer anderen Seite zu verlinken. Dann ist es dank Schlaflosigkeit mehr geworden und dann dacht ich, mach ich einfach nen Beitrag draus.

Comparing #XMPP against #email protocols is too limited. What sets #deltachat apart is *vertical integration* and being driven by UI/UX considerations. Cross-platform Apps and Bots use the Rust core library which connects with #chatmail relays and classic email servers based on a higher level API -- abstracting over SMTP, MIME, #OpenPGP etc. See https://chatmail.at
#webxdc apps in turn use an even higher level stable API abstracting over email/xmpp/... see https://webxdc.org/docs/
Hi @delta 
I am making updates to https://delightful.coding.social/delightful_activitypub_development and bumped into this interesting #SMTP to #ActivityPub proof of concept. Just a heads-up to make you aware, in case it is interesting for #DeltaChat in some way or other.
@pixelschubsi #webxdc in #DeltaChat doesn't use #webrtc for real-time channels, please, I recommend you to read and try out things before spreading fake information
for your information webxdc uses #iroh for #p2p in DeltaChat
The point is that DeltaChat didn't invent a new protocol, start something from scratch and write the software for it from the first line. As there is a saying:
Good programmers write programs from scratch. Great programmers find an already existing program and use it as a base.
#DeltaChat didn't invent #Email, #PGP, #autocrypt or new technology for #webxdc. Even WebXDC's real time channels don't use a technology invented by DC.
Considering that both #XMPP and #Matrix re-invented #decentralized communication while #email was already there, makes #deltachat more interesting.
The fact that DC didn't invent a new protocol for #InstantMessaging and just used the protocol which was already there, and also that how far has it gone, is mind blowing.
At first when I was chatting with @treefit, I already was developing a Matrix client(#chooj) for #KaiOS and it was the only decentralized IM which I was using and investing resources into. I was skeptical but then I thought it would be a good idea to invest into DeltaChat, as well as Matrix. His argument, of course, wasn't good. He was arguing that we need multiple options in the case one of decentralized IMs fail. However this convinced me to give DC a try.
But now, I see that DC has very unique advantages no other messenger has. Their moto is "playing the long term" game. Unlike Matrix which suddenly exploded, DC moves very slowly. As an advantage, DC is much more consistent, hassle free, has less bugs(in my experience) and has better UI/UX than many Matrix clients. But it has got several disadvantages. Matrix has tons more features which DC hasn't got or has added them just recently such as editing messages and reactions. And it is not yet suitable for public groups, like the ones we've got in the Matrix network.
Overall, if you want secure chat with friends or family or other people you trust, DeltaChat is a very good option and the experience is very good. And I haven't seen something like #webxdc in any other IM. However if you want something like #Discord guilds for a community, Matrix is the way to go.
BTW, DC currently lacks funding, thanks to what #Trump did with #OpenTechnologyFund(#OTF). If you can help in anyway, financial or otherwise, it will be extra valuable at this point.
Edit:
BTW, here are websites of webxdc and DC:
Whatsapp -> Meta -> 
Telegram -> IA d'Elon Musk ->
Signal -> servidors AWS Amazon ->
#DeltaChat -> 
our friends over at @rpgp just published a monster milestone, humbly tagged 0.16 
with
- streaming decryption and encryption
- post-quantum-cryptography
- API streamlining.
#rPGP is a full Rust implementation of #openpgp which counts among the fastest and most compliant implementations today, and includes security audits. Note: #deltachat uses a restricted subset of OpenPGP, and follows best practices (eg using the same ed25519 keys implementation as #signal) https://github.com/rpgp/rpgp/

De una conversación tecnológica:¿Da WhatsApp (WA) información a la policía?
El entendimiento general es que WA no da contenido de comunicaciones a la policía.
Da metadatos de comunicaciones a la policía, y los metadatos que da son sustanciales, ya que cosas como el nombre del grupo, descripción e icono son considerados «metadatos» por WA (no por Signal), e incluso contenidos de su agenda (y las agendas de sus contactos) se consideran metadatos.
Les defensoras de Signal señalarán que Signal no considera «metadatos» cosas como el nombre de grupo, la descripción o el contenido de la agenda.
La gente acostumbrada a servicios decentes como los de riseup, autistici/inventati, nadir, sinodminio, disroot o aktivix, siempre preferirán protocolos descentralizados donde cualquiera puede configurar su propio servidor federado, como delta.chat o xmpp; son los mejores.
Idealmente hospedados por colectivos decentes.

GPN23@tanja yes, there is a pre-discussed concept for sealed sender maybe along with sealed recipients while we are at it. Base idea is to use fixed-format alias chatmail addresses for recipients and allow unauthenticated sending from noreply@chatmailserver to such fixed-format alias addresses (which #deltachat devices learn about through chatting).
@delta thank you so much for responding :3
Are there any plans for something like sealed-sender?
I imagine that'd be rather difficult with existing mail standards.
At least for me, Signals sealed-sender has never failed me yet (apart from the first message in new conversations), at least the sealed-sender icon appears in every message I've sent in the info screen.
(How) could this be implemented in #deltachat ?
When I send a message using @delta, can people in control of the chat server see who sent it?
Can people in control of the chat server know what group I'm sending to, if it's a group chat?
As far as I'm aware, @signalapp prevents at least the first one, and has mitigations for correlation attacks (where one user sends a message, and the same 5 others happen to receive one at the exact same time, every time). Does #deltachat have that?
Am I missing something here? 
@rohden Heh, you caught it :) Indeed bots running some LLM for audio transcription or image generation exist. But they are not part of the UI/UX of #deltachat itself, or of its #chatmail core Rust library. Bots and #webxdc apps are behind extension points where we intentionally don't control or even know what people use.
@vascorsd I had something similar to that happen to me recently as well. I'm using a #prosody server, and I have my:
archive_expires_after = "5w"
... set in /etc/prosody/prosody.cfg.lua
Messages should be archived for 5 weeks.
Then messages sent in Gajim on one linux laptop were lost, when a second #Linux laptop who was subscribed to the same group, was turned off (absent from receiving messages) for 3 weeks. 2.75 of the 3 weeks worth of the group messages (where the laptop was turned off) silently never showed up, when #Gajim was re-opened on the second laptop.
This bodes very badly for me recommending XMPP to others. I now consider #DeltaChat to be a secondary choice, should something happen to #Signal (which is currently my privacy-respecting Messaging app goto).
Other clients who chatted in that same group, BTW: the latest stable #Monal in #iPadOS, and #Conversations in #Android
Prosody version is 13.0.0-1~bpo12+1, backend is sqlite, Gajim is 2.1.1. It was a private MUC, and OMEMO was used as much as possible.
By design, end-to-end-encrypting #deltachat and #webxdc apps only need ephemeral transport. It's a big deal. Let's compare:
- #matrix home servers maintain a cryptographic forever-chain of cleartext social-graph metadata.
- #WhatsApp servers maintain cleartext metadata visible to Meta.
- #Signal keeps encrypted metadata, hosted at GAFAM
#chatmail relays do not persist any social graph state, also not in encrypted form. A key goal of our designs: chatmail operators can sleep well at night :)
@delta is there any advantage for me using a selfhosted chatmail relay instead of my selfhosted docker mailserver when using #deltachat ?
I just plan to use deltachat in a family context where everthing would happen on my own mail server.
@bjoern @chfkch @delta well it shows that the #deltachat core library can run inside of a home assistant add-on. the same core library is also used for writing bots.
So should be possible, but I don't know #HomeAssistant development enough to say for sure. Like can I expose actions from an add-on, that you can trigger from the home assistant UI, or would I need to extend home assistant itself for that?
Hat irgendjemand schon mal versucht #deltachat für Benachrichtigungen aus Smarthomesystemen wie Nodered, Homeassistant etc zu nutzen? Oder gibt es ggf einen CLI Client mit ner API die man aus solchen Systemen raus aufrufen kann. Dementsprechende Bist könnte Delta Chat zu einer coolen Alternative zu Telegram machen.

The last two days saw the number of push notifications spike. Sometimes 80K Google Play push notifications happened per hour, while the baseline was more around 10-20K. These spikes probably indicate Internet availability. #deltachat is offline-first: you can write messages and attach media, create groups, use #webxdc apps, setup a second device etc. all without any Internet. Once it returns queued messages are sent out and cause push notifications. #OfflineFirst is crucial for resiliency.
