It is hard to sustainably support #OpenSource as government - after all, the public sector's subsidy programs tend to be short term focused, fragmented. They are sadly doing little to shift the billions now spent on proprietary US SaaS solutions towards sovereign open source, and have little staying power and permanence.

I'd argue the public sector should work with existing communities that have managed a sustainable financial model, commit to deploy these & shift real procurement money rather than be distracted by subsidies.

I will keep my argument short - and leave the time for discussion!

CryptPad is a collaborative office-suite that is end-to-end encrypted and fully open-source. The project has been operating for over 10 years and is used to collaborate on millions of documents each month on the flagship instance cryptpad.fr. In this talk we will introduce the product and its suite of applications. We will highlight some recent achievements from the last year including

We will also recap the financial situation of the project, and our plans looking ahead towards sustainability.

In the last few years, we've revived the idea of a student wiki at MFF CUNI, where the last attempt had languished for years. We'll talk about the technical side – choosing a platform, the problems we encountered, and our extensive modifications – as well as the organisational side, from getting institutional backing for our project to actually getting student contributions.

Through a combination of automated migrations and follow-up manual edits, we've consolidated a number of older, semi-abandoned platforms at the faculty to the new wiki. The entire software stack is FLOSS while also allowing integration with other university systems.

You can see the current state of the wiki at https://wiki.matfyz.cz, and our source code at https://gitlab.mff.cuni.cz/matfyzak/wiki/

Collabora Online introduced a new feature that lets users start a slideshow for everyone who has joined the presentation. This feature can be used during meetings where, instead of sharing the screen to present something, the user can now just start the slideshow inside the presentation document.

Isn't monitoring DNS queries a really bad idea? If the monitoring crosses the line to surveillance, we agree. Monitoring for bad actors is still needed and valuable for cybersecurity. Building such a platform in Open Source and running it as a non-profit is much better than letting commercial actors consume this data without making it an open data commons. For sure many won't protect the user's privacy the way we do.

This is the story about the DNS TAPIR Open Source project - the reason we started it, our core principles and the architecture .

Localization is often seen as a purely technical task, but for many contributors, translation work is deeply personal. It is about cultural identity, community belonging and keeping a language alive in fast-moving technical ecosystems. Working with the Spanish localization team for OpenTelemetry, I discovered that what brings people back is not only the desire for accurate terminology, but the joy of building something meaningful with others who share the same language. Contributing to localization OpenTelemetry motivated me to start a new Romanian localization group and inspire contributors who had never participated in open source before. This talk explores why localization communities thrive, what motivates contributors beyond the mechanics of translation and how language-driven belonging can open the door to new contributors in cloud native and open source projects. I will share practical lessons, common challenges, and strategies for creating or sustaining localization groups that make both software and humans better.

Taiga is a Spanish open-source project management software that was created in 2014. After achieving success with over 20 million users, a rewrite is started in 2021 in order to modernise the application. However, this soon came to a halt: the original team is no longer able to continue the project. So, after 10 years of development and with many users eagerly awaiting this sequel, is this the end?

Thanks to the magic of open source, the story continues. A French cooperative that was also working on Taiga, took the project under its wing, ready to start afresh.

Join us to discover the origins of Tenzu (formerly Taiga-Next), find out where we are now, and learn about our future plans.

With a live demo I will show how I distribute my (mostly long-form) content (POSSE) from Drupal (CMS) to multiple Nostr relays. After this demo I will explain the technicals details how this works (using the Nostr-PHP library https://nostr-php.dev and used Drupal modules, https://www.drupal.org/project/nostr\_content\_nip23, which I maintain).

As enterprises and service providers transition to virtualized and cloud-native infrastructures, the need for scalable, high-performance security becomes critical. FD.io's Vector Packet Processing (VPP) platform has emerged as a leading open-source framework for fast packet processing, but how well does it handle modern IPsec workloads in Virtual Network Functions (VNFs) and Cloud-Native Network Functions (CNFs)?

In this talk, we dive deep into the architecture and implementation of IPsec within FD.io VPP. We'll explore real-world performance benchmarks, discuss recent improvements, and present best practices for deploying secure, high-throughput IPsec tunnels in containerized and virtualized environments. Attendees will see how VPP's modular pipeline enables flexible integration with orchestration systems, and how it can be tuned for different network function scenarios-from high-density edge sites to large-scale data centers.

Whether you're building secure SD-WAN, 5G core, or edge networking solutions, this session will provide actionable insights on leveraging open-source VPP to deliver robust, scalable, and efficient IPsec-powered VNFs and CNFs.

Key Takeaways: - How FD.io VPP implements and accelerates IPsec for virtualized and cloud-native deployments - Tuning and scaling techniques for maximizing IPsec throughput and minimizing latency - Integration patterns for orchestration and real-world deployment considerations - Lessons learned from operational use cases and performance testing

Join us to learn how open-source innovation is redefining secure, high-performance networking for the next generation of infrastructure!
