Ich erkläre im NET⫽SPLIT Podcast, wie man #Matrix als iterative Verbesserung von #XMPP hätte umsetzen können, statt das Rad neu zu erfinden. Noch mehr hot takes zu Matrix vs XMPP gibt es im Rest der Folge, die auf PeerTube oder in der Podcast-App eurer Wahl […] [Original post on gultsch.social]

Google Play review times keep getting longer and longer. I've been waiting three weeks for Google to release the latest version of #Conversations_im. It's not a security-critical release, but what if we ever need to publish something urgently? Luckily, with […] [Original post on gultsch.social]

Dass ein chronologischer Feed auch nicht neutral ist, ist auch nochmal eine interessante Ergänzung zur Algorithmus-vs.-Gatekeeper-Debatte, die Ückück (@ueckueck) und ich in der ersten Netsplit-Folge „Gibt es das Fediverse“ hatten. https://gultsch.video/w/kqhyU8g3ToUYYuKT3t7A4m

Selber Infrastruktur bereitzustellen war einmal vollkommen normal. Ückück und Daniel erzählen von früher. Die ganze Folge #2 von NET⫽SPLIT gibt es auf PeerTube oder in der Podcast-App eurer Wahl. 🎬 https://gultsch.video/w/pAoKnpBVCY3pRt6YhnV32h 🎧 […] [Original post on gultsch.social]

Ich habe einen neuen Podcast: NET⫽SPLIT Jetzt ist es offiziell, @daniel und ich haben zusammen einen #Podcast, @netsplit \o/ Geplant ist ein Laberpodcast rund um #OpenSource und Dezentralität, auch wenn die ganz genaue Ausrichtung noch nicht 100% fest steht […] [Original post on dresden.network]

Das Kind hat einen Namen. Ückück (@ueckueck) und ich machen jetzt den NET⫽SPLIT-Podcast zusammen. 😊 🌐 https://netsplit.fm 🎧 https://antennapod.org/deeplink/subscribe/?url=https://netsplit.fm/feed.xml #Netsplit #Podcast #PeerTube #Fediverse #DigitalSovereignty #DigitalIndependence #XMPP #Jabber

Gibt es gute #Messenger? NET⫽SPLIT Folge #2 Letzten Monat hat @daniel mir noch Fragen zum #Fediverse gestellt, diesen Monat geht es weiter mit einigen meiner Fragen zu (dezentralen) Messengern. In Folge zwei unseres neuen Podcasts @netsplit sprechen wir u.a. darüber, warum er sich ausgerechnet […]

Während ich im letzten Monat Ückück (@ueckueck) über das Fediverse ausgefragt habe, geht es in der zweiten Folge von NET⫽SPLIT um XMPP. Ückück fragt mich, wie ich zu XMPP gekommen bin, wie ich an neue Features herangehe und was ich von Matrix halte […]

Diese Woche sind coole Dinge™ passiert! Stay Tuned :D

Stay tuned!

The Fair Tech Summit is coming to an end. Shortly before closing, I gave a quick, two-minute lightning talk on Conversations. #FairTech #Conversations_im #XMPP #Jabber

A recording of the talk “Jabber/XMPP: 25 Years of Digital Independence” that I gave at Linux Days in Prague the other day is now available online. Learn why open source is necessary but not sufficient for digital sovereignty and why we need open standards like XMPP […]

Mastodon, Element and Conversations on the same slide? What is this, a crossover episode? https://super-stack.eu #Mastodon #Element #Matrix #XMPP #Conversations_im #Jabber #SuperStack

I’m in Luxembourg for the Fair Tech Summit and Open Source Conference Luxembourg. The Fair Tech Summit marks both the conclusion of the Mobifree project and the kickoff of the SuperStack project. Great to meet our partners and friends from F-Droid, /e/OS, UnifiedPush, Delta Chat, Phosh, Taler […]

If you are in Prague for Linux Days remember to come in early to catch my talk on Jabber/XMPP and 25 Years of Digital Independence. It's the first talk of the day at 10am in room 105. https://pretalx.linuxdays.cz/linuxdays-2026/talk/H7ANQQ/ #LinuxDays #LinuxDaysCZ #XMPP #Jabber […]

We've just finished setting up our XMPP stand at LinuxDays (@linuxdays) in Prague. If you are in the area make sure to visit us. We are here all day today and tomorrow (Sunday). We have stickers and buttons! #XMPP #Jabber #LinuxDays #LinuxDaysCZ

I just released an update to Conversations that fixes a regression in the accessibility of the attachment selection. Accessibility is important to me, and I apologize for any inconvenience caused by this. If you notice any accessibility problems, please let me know immediately. #XMPP […]

Google is raising the minimum SDK version for several core AndroidX libraries to 24 (Android 7). This means that even well-intentioned app developers will have a much harder time supporting Android 6. #Android #OpenSource #Fdroid #Google

RE: https://sciences.social/@annasdtc/117224123424001867 Not everyone can or should self-host, but the technology that enables it—federation, open standards, and vendor independence—also allows cooperatives, municipalities, and community groups to run their own infrastructure […]

Im Interesse der Dezentralität gibt es meinen Vortrag „Jabber/XMPP: 25 Jahre Digitale Souveränität“ von den Datenspuren letzte Woche übrigens auch auf meinem PeerTube. https://gultsch.video/w/hNgNdVEUxMDex9xqrcofD5 #Datenspuren #XMPP #Jabber #PeerTube #Fediverse

Ich hab bei meinem Interview mit Stephanie (@ueckueck) noch einiges darüber gelernt, wie Reichweite im Fediverse funktioniert und was die Vorteile großer Server sind. Schaut am Wochenende doch mal rein! Tipp: Funktioniert auch gut als Audio-only-Podcast. 🎧 […]

RE: https://gultsch.social/@daniel/117326565942500394 Now that Conversations is free on Google Play, it should be a lot easier to onboard friends and family onto Jabber/XMPP — the only truly independent messaging solution. Maybe give it a shot this weekend! #XMPP #Jabber #Conversations_im […]

RE: https://gultsch.social/@daniel/117280438824908947 Google finally managed to publish Conversations 2.20.2 last night, after apparently very thoroughly reviewing it for 16 days. The current version, which has been available on F-Droid for multiple days, is 2.20.3 😂 #FDroid #Conversations_im […]

RE: https://gultsch.social/@daniel/114550851233805523 It took me a moment to get back to writing long-form content, but I’m enjoying it a lot. My last three posts have been XMPP-adjacent, but I think I want to branch out a little bit with my writing. https://gultsch.de/posts/

F-Droid (@fdroidorg) is usually pretty quick with publishing updates these days, and both of my apps are built reproducibly—which means they are signed with my personal key. If you want an even more direct line to my apps, you can use my personal F-Droid […] [Original post on gultsch.social]

Conversations is now permanently available for free on Google Play. Google doesn’t deserve me and my money anymore. https://gultsch.de/posts/breaking-up-with-google-play/ #XMPP #Jabber #Conversations_im #Android #FOSS #OpenSource #Google #GooglePlay

„Klickwege die keinen Sinn ergeben“, @ueckueck hält nicht viel von Instagram. Unser komplettes Gespräch über die Alternativen zu Instagram, Twitter und Co findet ihr hier: https://gultsch.video/w/kqhyU8g3ToUYYuKT3t7A4m Oder für den Nachhauseweg in der […] [Original post on gultsch.social]

Vor vier Jahren habe ich mir einen Mastodon-Server aufgesetzt. Ganz verstanden hab ich das mit dem Fediverse aber noch nicht. Deshalb bin ich kurzerhand nach Dresden gefahren und habe mir das Ganze nochmal von ückück erklären lassen. Zwischendurch kam auch die Frage auf, ob es das #Fediverse […]

• A car hit a pedestrian • An LLM hacked a website • An XMPP client ordered a shipping container full of cocaine from Colombia I’m starting to see a pattern.

RE: https://fosstodon.org/@xmpp/117304079425733599 I’m going to be in Prague for #LinuxDays (@linuxdays). I’ll be giving a talk on Sunday at 10:00 about XMPP and 25 Years of Digital Independence. You can also find me at the #XMPP stand if you’d like to chat, ask questions, or grab some […]

Conversations 2.21.0 (releasing around Oct 20, 2026) will enable “Require channel binding” by default for new installs. If you run a public #XMPP server, please ensure it supports SCRAM-*-PLUS channel binding so new users can connect.

Die Aufzeichnung meines Vortrags „Jabber/XMPP: 25 Jahre Digitale Souveränität“ von den #Datenspuren ist schon online verfügbar. https://media.ccc.de/v/ds26-678-jabber-xmpp-25-jahre-digitale-souveranitat #XMPP #Jabber

This is unacceptable. The Google Play app review process now regularly takes longer than a week. I understand that the pipeline is clogged with AI slop, but #Google needs to prioritize #Android apps that have been around for 12+ years and push updates only once a month.

I’ll be speaking at the Open Source Conference Luxembourg on October 7th! Join me and @larma as we talk about Jabber/XMPP and 25 years of digital independence. https://pretalx.com/open-source-conference-luxembourg-2026/talk/Y3E9VJ/ #OSCL26 #Jabber #XMPP #OpenSource #DigitalSovereignty

A lot of my colleagues are concerned that #XMPP could kill all of humanity by the end of this decade. This is not a marketing stunt.

I wrote a blog post reflecting on Jabber/XMPP, whether it’s ready for wider adoption, and how we actually get there. https://gultsch.de/posts/how-do-we-gain-traction/

Currently doing research for another blog post, and I noticed that WhatsApp and Signal only gained the ability to edit messages in 2023, whereas Conversations has had it since 2016. To this day, both WhatsApp and Signal lack crucial features that […] [Original post on gultsch.social]

There used to be an urban legend that WhatsApp was listening to everything you said. In reality, it was mostly confirmation bias: if you talked to a friend about a dream vacation and later saw ads for it, chances were high you had already googled the destination. Anyway, Apple is now building […]

You know how it’s become impossible to buy anything on Amazon because you’re given the illusion of choice, but everything is just drop-shipped junk from China? I'm starting to have a similar feeling toward new open-source projects post-LLMs.

I promised an English version of my „Jabber/XMPP: 25 Years of Digital Independence“ talk, and it looks like I’m going to Prague for LinuxDays 2026 in October! https://pretalx.linuxdays.cz/linuxdays-2026/talk/H7ANQQ/ #XMPP #Jabber #DigitalSovereignty

I'm getting out the good streaming setup for today's 29th XMPP Summit. ☺️

RE: https://gultsch.social/@daniel/117195237916916162 If you are excited about my upcoming talk on #XMPP, I encourage you to read my essay, “Jabber/XMPP: 25 Years of Digital Independence” (if you haven’t already). The talk will be more technical in nature, but the essay hits on similar topics […]

I have been invited to the “Datenspuren” conference in Dresden to speak about Jabber/XMPP and 25 years of digital independence. The talk is going to be in German, but I've submitted an English version to other conferences. https://talks.datenspuren.de/ds26/talk/GF8KMU/

The Italian email, XMPP, and blog hosting provider Autistici/Inventati has been designated a “global terrorist” and put on a sanctions list by the US regime, which, among other things, will severely limit their access to financial systems. https://www.inventati.org/campaign/press #Jabber #XMPP […]

RE: https://gultsch.social/@daniel/117151276111833796 Something that bothers me about the push for digital sovereignty is that a lot of it seems to be motivated by nationalism and anti-American sentiment. That's why we need standards and federation, so instead of just switching to an instant […]

I wrote a blog post on Jabber/XMPP and 25 years of digital independence. https://gultsch.de/posts/25-years-of-digital-independence/ It shares a title with my upcoming talk and touches on similar themes around open standards, collective ownership, and avoiding vendor lock-in. However, it is an […]

After a full conference season of talking about #UnifiedPush, I’m now preparing a talk on XMPP again. I haven’t presented on XMPP in a while because I didn’t feel like a lot was happening. That’s changing now. #Jabber #XMPP

RE: https://fosstodon.org/@xmpp/117123487150836382 In addition to our regular summits in Brussels in January, we are doing an online-only summit this year. Our aim is to dramatically reduce the barrier to entry for international members of our community and anyone who would otherwise struggle […]

With Google closing down the #Android ecosystem more and more, I think there is a lesson to be learned about relying on something that is technically open source but largely controlled by a single company. That’s why I would be very careful building something on top of #Matrix.

RE: https://grapheneos.social/@GrapheneOS/117057099753905023 I used to have a lot of brand loyalty for Google smartphones. I started out with a Galaxy Nexus in 2011 and now use a Pixel 9 Pro. I guess I need to hold on to my current phone until postmarketOS becomes usable on Fairphones.
