Radicle: A better, peer-to-peer, home for Open Source

Sat 21 Nov 2026 • 12:20 (CET) • Basic
Auditorium

Open Source Software (OSS) may have taken over the world, but did someone take control of OSS itself in the process, locking it into a proprietary platform, controlled by a single vendor? Is this still a sustainable path today, in the time of trade wars, volatile tariffs, GenAI mandates and countries fighting for data sovereignty? The future of OSS as a global public good is at risk. The need for a resilient, community-owned alternative has never been more urgent.

This talk will introduce you to Radicle, a new, decentralized code forge that’s built on a peer-to-peer architecture.
We’ll explore how Radicle works and how it extends Git to create a secure and resilient network for code collaboration. We’ll cover its peer-to-peer replication protocol, its decentralized identity system, and its novel approach to code discovery.

This talk is for developers of all levels interested in the future of Open Source. You’ll leave with a better understanding of the challenges involved in designing and running distributed, peer-to-peer systems. You’ll also learn how you can start mirroring / migrating your code to the Radicle network, so you can #FreeYourCode !

Embracing Chaos: Harnessing the Power of Chaos Testing for Resilient Systems

  • Testing is essential to ensure that your software application performs as expected. No doubt about it. But even if your application runs smoothly in a testing environment, unexpected incidents can occur in production, such as a crashed database or a lost connection to a third-party service. To ensure your application can handle such incidents and minimize their impact, you need to incorporate chaos testing into your delivery process. In this workshop, we will start with a brief introduction to k6 for backend performance testing and we’ll explore how to implement chaos testing using k6 for two backend services, to help you ensure the resilience of your application.

Liberate your data using Redis Stream and Go

  • Redis is an in-memory database popular for many use cases, such as content caching, session stores, real-time analytics, message broker and data stream needs. Since version 5.0 of Redis a new data structure, Redis Streams, dedicated to managing streams has been introduced. Using Redis Streams, anyone can do a lot more than what was possible with Pub/Sub, Lists or Sorted Sets in the data stream domain. In this all-hands session, we’ll walk you through the basics of how to use Redis Streams, how consumer groups work, and finally show a working application using Go that uses Redis Streams.
