Let’s gather designers, frontend developers and WordPress users interested in free/libre workflows for building modern websites. We’ll discuss static front-ends, no-code visual builders, headless CMS, and how tools like Silex can fit into this ecosystem. The goal is to share experiences, compare approaches and connect people who want a more sustainable, maintainable and libre way to build websites
There is something between binary and quantum. Binary computing has reached the limits of scaling while Quantum computing needs a century more research to become practical available. Ternary computing is possible and exciting. We are enthusiastic on what we have done so far (motherboard, CPU in FGPA, communication via serial, an assembler, a deassembler, a compiler for a rust-like language, emulator, debugger and many plans.
Let's talk about ternary logic, gates, practical applications and what you'll need.

Free Software is a great way to share ideas, solutions and make the world a better place. We all know that already, but sometimes it is helpful to gather with like minded people in my own country, to drink something and have fun, while we think about how can we leverage free/open source for a better society.
This BoF is the place for gathering Portuguese and get to know each other. Also, a light overview about "Public Money? Public Code!" and "ANSOL - Associação Nacional para o Software Livre"
A collaborative working session on mapping, triaging, and coordinating 2038-class rollover remediation across the open source ecosystem — where the real problem isn’t ancient systems, but invisible dependencies.
The 2038 problem isn’t waiting in retired Unix servers. It’s 32-bit time_t assumptions still being baked into modern libraries, protocol implementations, and embedded toolchains shipping today. Many 64-bit systems depend on components that simply cannot represent time beyond 2038 — asbestos in the walls, not a single leaky pipe.
This BoF runs a collaborative thought experiment: if your government demanded a credible 2038 exposure assessment in 12 weeks, where would you actually start? What tooling exists? What’s missing? How do findings at the repository level roll up into something actionable?
To ground the discussion, we’ll introduce the 2038-Class Risk Exposure Matrix — a lightweight framework for comparing unlike risks across impact, uncertainty, remediation difficulty, and blast radius — along with a CC BY 4.0 workshop and full facilitation plan designed to help teams inventory their systems, surface unknowns, and translate technical findings into clear, decision-grade signals.
→ Here is the Matrix, with workshop and facilitation materials
Distro maintainers, embedded developers, and infrastructure engineers are invited to share inventories, swap remediation strategies, identify high-impact targets, and surface coordination gaps. We’ll map the technical landscape and connect the people already working on the problem.
Bring your war stories — your known-knowns and your known-unknowns.
Arch Linux is a lightweight and flexible rolling release Linux distribution that focuses on simplicity, modernity, pragmatism, user centrality and versatility.
Members of the Arch Linux staff have historically always attended FOSDEM. This BoF session will give a status update on the distribution, adjacent projects and future plans.
There will be a short presentation followed by a Q&A session with Arch Linux distribution maintainers and project developers.
Localization of free software is essential, yet often left in an unwell condition even in significant projects used by many. But it's what makes software truly yours! Come and share your experience with the localization process of your projects. Leave inspired. Let's chat about what you find important in localization, what makes you happy, and what complicates it for you. What do you want the best libre localization to have and provide to its users?
A space for the localization community where every hacker can share their experience and make FOSS localization better, not only confident speakers with selected talks.
Like each year, every person interested in localization is welcome! The Weblate team will be there. We will be gathering feedback, discussing collaboration within the community, Weblate plans, features, bugs, and more.
In this BoF teams from PenPot and KDE will come together to review:
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Since we don't have a booth this year, we want to take the opportunity for a more focused discussion about all the things you miss in Haiku, as a user or as a developer, to enjoy using it.
Hardware support, features, documentation, accessibility (there's a lot to do there too)… What's missing for Haiku as a daily driver to you?
As data rates continue to rise and electrical interconnects approach their physical limits, somehow interest in optical (photonic) technologies is gaining momentum. This BoF session will explore how community collaboration of software and hardware developers, hobbyists, physicists, engineers etc can contribute to next-generation optics (photonics) tools. We will discuss the current ecosystem of optical (photonic) tools, how newcomers can get started, the key challenges, and whether there is momentum to propse a dedicated devroom next year.
Sailfish OS has been providing daily-usable Linux on phones for over a decade, with its unique blend of gesture-based mobile interface, Android AppSupport and enthusiastic community. Join the Sailfish OS Community Birds of a Feather event to talk about Sailfish OS, meet the Sailfish community, share experiences and ask questions.
The Jolla Team will be present to answer your questions and share insights about future developments.
The Sailfish OS BoF has been running for many years at FOSDEM and always attracts an enthusiastic community. We look forward to seeing you there!
In this Birds of a Feather session, members of the OpenStack Community will have the opportunity to get together to discussion issues ranging from development to operations. It is also a goal of this session to welcome potential contributors and users who might want to learn more about the project and how they can get involved.
The OpenStack project is part of the OpenInfra Foundation. Code for the project is hosted at opendev.org
AI alignment is the effort to design Artificial Intelligence systems so their goals, behaviors, and decisions are consistent with human values and intentions, making them safe, helpful, and reliable. In the context of open source, this BoF will explore what it means for AI to be aligned with open source (what we have built, know, value, expect). Insights will inform work we're doing in the CHAOSS Community as part of AI in Open Source Working Group
AI doesn’t have to slop. OpenMates is aiming to not just be an open source AI agents web app, but an alternative to big tech AI platforms with both better usability, functionality, ethics, user interests first, privacy and provider independence. Focused on everyday users and everyday tasks, without requiring deep technical knowledge. While also being an awesome software, API and CLI to use for every developer. OpenMates can not only answer questions but use various apps to fulfill tasks, can consider personal infos if the user explicitly chooses that (while still focusing on data minimization and maximum user privacy), and has a general focus on educating and inspiring users. And this is only the early beginning.
After over a year of work and over 3000 commits, OpenMates is currently available in an alpha version as both a fully featured self hosting edition on GitHub & on OpenMates.org for those who don’t want to self host. Web app and REST API are usable, CLI is planned. OpenMates currently uses various existing APIs / LLM providers, and support for offline models via Ollama, LM Studio, etc. is planned for the months ahead.
Join the development meetup to learn more about OpenMates, shape its future and contribute.
