No coins, no chains, no big machinery but plain, efficient and scalable decentralization, leveraging the largest open internet messaging network ever created by humans ... made safe, fast and resource efficient with #chatmail servers using strong and audited #interoperable #cryptography. It just works (tm) in many places where Signal and WhatsApp fail today. It's time to reclaim "decentralization" from techbros, insist on real-life #resilience and trust this cute figure from @xeniax ⏚ :)

Despite not having a lot of money we are yearly subscribed to give 300eur to the #foss #forgejo platform of @Codeberg who are currently suffering sustained network and abuse attacks

Codeberg (@Codeberg@social.anoxinon.de)

We are currently suffering from a network-level DDoS attack. Or maybe just a single actor. Anyway, our downlink is jammed.

Some of our #webxdc developments takes place on Codeberg. Thanks for persevering! #hugops

Interested to take a little tour through how #deltachat apps and the #rustlang core library are wired together? @treefit and @npub1g9ps...jy26 provide a deep-dive into the history of apps migrating from a C-Foreign-Function-Interface to a #Rust based JSON-RPC mechanism, with entertaining horror stories like how an iOS release some years ago could delete profiles without the user intending it 😬 The post also highlights a few areas where folks interested to help could start ...

The #chatmail #fosdem talk from @npub1xgy7...s8pa is public. It goes into topics such as - why chatmail servers? - how to setup a server with your child - (avoiding) spam filtering - metadata and guaranteed end to end encryption in #deltachat - #cryptographic #interoperability for email message routing Thanks to attendees for the great energy even if was the last talk on the day and also for questions and conversations afterwards!

Delta Chat is since some years gaining usage by people forced to flee. Several of our contributors themselves migrated and others fear they might soon have to. Our technical designs and social approaches rest on a #RightToExit on virtually all levels. No walled gardens. No presidents. It's true that #deltachat is a money-poor project compared to mainstream messengers ... But the question at hand in 2025 is: which messaging system will persevere when corporate platforms get corrupted and break?

Six times so far ... is how often important parts of #deltachat were independently #security audited and analyzed. Thanks to IncludeSecurity, Cure53, Applied Crypto Team at ETH Zuerich and Radical Open Security. Last audit is from December 2024 covering @npub1f5gx...3gr2 , the minimal #OpenPGP Rust library that is gaining traction with others projects as well. Shout-out to dignifiedquire and @npub18sqs...29ap for their excellent maintenance! For more info on Delta Chat related security audits:

The ecosystem is moving ... away from corporate centralization and mindsets. Billionaires are out, federated and multi-player systems are in, if we gather the many chats, gossips and happenings around #fosdem correctly. Dispersing ourselves around Bruxelles the last couple of days was very enjoyable (thanks Sun!) and helpful to orient in convivial directions in this otherwise extraordinarily stupid 2025 timeline ... thanks to the many people we enjoyed conversations and hang outs with! ❤️

Today #fosdem at 6pm there are sessions about #chatmail and #deltachat and #webxdc ... Modern email devroom k.4.601 ... Happy global switch day :)
