Miru is a set of web-based tools for media editing. In this talk, I'll present the video editing features that we're developing, and our journey to intuitive collaboration with offline support using CRDTs. I'll outline some similarities and differences between a video editing timeline and a rich text document, the CRDT libraries we evaluated, and what approaches did and didn't work for our editor.

PouchDB and CouchDB have been an absolute Local-First Dream Team since 2013. In this workshop, we'll show you why. Join us for hands-on time with PouchDB itself, a look at a fleshed out demo app to see how the Open Source projects PouchDB, CouchDB and app state fit together, and a quick glance at a convenient Open-Source way to easily host your own CouchDB.

We'll cover:

We'll also share a bit about why we believe it is important to build on Open Source projects with a clear governance structure, so you can rely on it for the long-term.

Time permitting, we'll share some of the extraordinary projects we have built with PouchDB & CouchDB:

We introduce Peergos, a peer-to-peer protocol for end-to-end encrypted storage, social networking, and application hosting built on top of libp2p. Peergos combines cryptographic identity, content addressing, and decentralized access control into a unified protocol where users fully control their data, identity, and applications without relying on trusted servers.

Instead of treating encryption as an add-on, Peergos integrates cryptographic capabilities directly into its data model: files, directories, social data, and application state are all encrypted and access-controlled by default. We will explain the design of Peergos' capability-based access control, how key rotation and sharing work in practice, and how identity portability is achieved without central authorities.

We will also introduce the Peergos application sandbox, which allows untrusted applications to operate over private user data without exposing plaintext or keys. This enables privacy-preserving apps such as social feeds, collaborative editing, and backups to run directly on encrypted storage.

The talk will include live demos and a discussion of performance trade-offs, limitations, and open problems in decentralized encrypted systems, including search, discovery, and offline access.

This talk is a call-to-action to join our campaign to convince the European Union that, in order to secure its digital future, it should invest in open source maintenance via an EU Sovereign Tech Fund (EU-STF).

Right now, the EU is negotiating its multi-year budget for the period of 2028-2034. Traditionally, the EU budget has been focused on regional development and agriculture, but more and more policymakers are realizing that investment in our digital infrastructure is just as important as maintaining physical roads and bridges. Last year at FOSDEM, we discussed with you what an EU fund for open source maintenance should look like. A lot has happened since then: We have conducted an in-depth study into the political, legal and economic feasibility of an EU-STF, building on the successful example of the German Sovereign Tech Agency. We assembled a coalition of supporters from industry and civil society, and we have presented our proposal to the European Parliament and Member States.

Now it's time to take the campaign to the next level and we need your support to make it happen. The goal of this session is to present the findings of the feasibility study for the EU-STF and demonstrate why mission-driven investment, coordinated by the public sector, is important for the diversification of Europe's funding landscape. It will demonstrate concretely how such a proposal can directly improve the sustainability and health of the open source community globally, and why this is so important for Europe in achieving its digital future.

OCapN (Object Capability Network) is a secure messaging protocol designed for the next generation of distributed applications. It leverages the capability security model (if you don't have it, you can't use it) to provide secure, peer-to-peer functionality with ergonomics that resemble ordinary programming. It has a rich set of features including promise pipelining, network transport agnosticism, error handling across networks, distributed acyclic garbage collection, and third-party handoffs providing powerful ways to share references with any peer. This talk will provide a tour of the protocol and show how it makes distributed, peer-to-peer development easier.

In recent decades, the internet has increasingly become centralized, shifting from its hacker-driven origins into a cartel of advertising companies. It won't get better if we allow these same companies to drive the design of the web browsers and their protocols.

Within hacker communities, many solutions have been developed to mitigate centralization, but their adoption has been limited, often because they require specialized expertise to be operated safely.

In this talk I'll introduce you to a new open-source project that aims to provide an accessible alternative by building a web browser that is able to fetch web content using the BitTorrent protocol in tandem with the Tor network.

We will dive into the ethical, security, and privacy trade-offs at play when designing such an alternative web.

The IvI Project: https://ivi.eco

Historically, peer-to-peer communication has been at the heart of the internet since its early days, reaching its peak in the late 90s when the web truly became a platform for sharing knowledge and art. For a moment it felt like we could exchange freely with anyone else. Unfortunately, that did not last long: legal restrictions, centralization and the emergence of commercial streaming services did eventually reshape the internet.

But the peer-to-peer spirit did not die. Over times many tools have been developed to try to keep the web decentralized and open. They are all contributing to forge a vision in which the internet network must be owned and operated by its users.

The project "IvI" that I'm introducing to you tries to bring those pieces together in a way that makes it accessible to anyone: a web browser that streams web content using BitTorrent while guarding privacy using the Tor network. It allows people in different parts of the world to help each other access content freely, even when local internet providers or policies impose restrictions on torrenting.

Rebuilding the web using this model allow us to mitigate the risks of mass surveillance and censorship by design. Though seeding activity is public, the decentralized nature of the network makes it difficult to trace who is accessing what, or from where. It also builds solidarity into the web itself: users helping users across borders through open technology... but it does also raise complex ethical questions.

When users set up their "Akoopa" browser, they will have the choice to operate under a public or private (cloaked) profile.

By choosing a public profile, the node will communicate with the BitTorrent mainline DHT, it participates as an active node in traditional BitTorrent swarms. But here's the twist: a public node also exposes itself using an onion service which is only advertised to peers running the IvI stack. On the other hand, all the HTTP browsing traffic goes through Tor, effectively preventing websites (or their advertisers) from correlating the torrenting activity.

Alternatively, by choosing a private profile, all communications will go through Tor. This means that the node can not directly communicate with BitTorrent mainline DHT. Instead, it relies on the overlay network of public IvI nodes to proxy its requests. In such situation it can participate only passively with the traditional BitTorrent nodes, but it is actively supported by the other IvI nodes in the swarm.

With this design in mind, and a carefully hardened BitTorrent client implementation which is respectful of Tor bandwidth and exit policies, we should be able to work around the issues traditionally encountered when torrenting with Tor.

This initiative is not commercial, not governmental; it is just a community effort to reclaim the web's original spirit. It's a simple idea that poses this question: What if we delivered the web itself through torrents? The technology exists; now it's about putting it together and doing so collectively to figure out how to make it work for everyone.

Embedded products are at the core of the Cyber Resilience Act, yet they face unique compliance challenges. Hardware vendors ship heavily patched BSPs, software modules often diverge from upstream, and reliable identification of modified components is still far from solved. For teams building products on top of these layers, translating CRA requirements into daily engineering practice is not straightforward.

This talk provides a practical overview of where CRA compliance currently stands for embedded devices, using Yocto Project–based workflows as a representative example. We will explore what is already achievable today with existing tooling (SBOM generation, vulnerability scanning, provenance capture), and highlight the gaps that still require industry-wide definitions - from consistent software identification to handling vendor modifications and long-tail dependencies.

Participants will gain a grounded, realistic understanding of how CRA obligations map to actual embedded development, what can be implemented now, and where the ecosystem still needs collective work to reach a "working" state.

Power saving has always been a major preoccupation in embedded systems, as by definition, they could have energy constraints. As embedded systems become increasingly pervasive, from IoT devices to industrial controllers, power efficiency is more critical than ever. This talk is aimed at developers, system integrators, and Linux enthusiasts. Whether you're optimizing a battery-powered board or a power sensitive industrial board, you'll walk away with practical insights and actionable tools. This talk will explore how to reduce electrical consumption on an embedded Linux system by leveraging software techniques such as kernel low power state (Suspend-To-RAM, Suspend-To-Disk), devices management. We'll cover how to disable unused peripherals or scale CPU frequencies
