lwresd was present long ago in Debian 4, acompanied by the libc library plugin libnss_lwres. It was intended to be a simpler cache than a standard name server, but it never gained wide adoption. Because it offered no significant advantages over using a DNS server like named directly. It was removed from BIND9 after version 9.11.

I have a few ideas on how to use it over Unix domain sockets to unlock new features. With some significant modifications to the original concept, it may make sense to revive the lwresd daemon.

In this session I'll share some challenges we faced at Wikimedia Deutschland with partially translated pages. We have some interesting example cases such as sentences which are partly left-to-right and partly right-to-left. I'd like to open up for discussion so we can share insights on how to approach such cases to get the best outcomes, and how to balance tradeoffs to avoid very confusing text.

“Privacy-invasive cloud services,” “isolated users” and “small, disconnected instances” are what comes to mind when we think of self-hosting. It gives users control, but it also isolates them, with each server becoming a separate island.

Cloudillo changes this. It is a self-hosted application platform that makes collaboration extensible, privacy-preserving, and organic - letting groups and organizations collaborate freely across different installations without relying on any centralizing infrastructure, while keeping their data private and under their control.

At its core, Cloudillo provides all the building blocks of a modern collaboration suite: file storage, real-time database, live editing, social interactions, and user identity.

But what's the kicker with Cloudillo? It is that these are not closed features, but open APIs developers can use to build new applications that integrate seamlessly into the platform. A built-in DNS + PKI-based identity layer enables people and organizations to connect securely, exchange data, and seamlessly share both content and applications across independently hosted Cloudillo instances - without any third-party coordination service.

Cloudillo's entire backend is delivered as a single 30MB Rust binary, with no external dependencies. It emphasizes simplicity, performance, and security. Developers can deploy it in minutes, extend it in Rust, or build applications in TypeScript, then immediately gain access to a global framework for distributed collaboration.

This short talk introduces the concept behind Cloudillo, explains its technical foundations, and demonstrates how developers can create their own apps - apps that reach beyond a single server, thanks to Cloudillo - the platform that aims to make privacy-first collaboration not just possible, but convenient and open for innovation.

Join me for a fast-paced tour of OpenProject's most impactful updates over the past year-from powerful portfolio management enhancements to much requested service management features, such as internal work package notes.

This session will also spotlight our long-term tech strategy to bring real-time text collaboration to every corner of the platform, enabling teams to co-create work packages, meeting notes, and other project management artifacts with ease. Discover how we're leveraging and extending BlockNote, the rich-text editor already powering applications like openDesk's Notes and Mijn Bureau's Docs, to bridge the gap between quick te sketches and fully-fledged project plans. We'll also invite developers to explore our BlockNote extensions, making it easier than ever to integrate work and task management into their own platforms.

Further, I will give an outlook on our strategy to help project teams to migration from Jira Data Center and Confluence to OpenProject and XWiki respectively.

Whether you're a user, contributor, or developer, this talk will inspire you to reimagine collaboration in open-source project management.

Given a large enough network of distributed nameservers, updating their configs and keeping all of them in sync becomes a highly error-prone activity. The problems multiply when multiple sysadmins and different operating systems are involved. We have created a low-complexity solution for syncing the NS configuration and keeping all servers aware of the current shape of the network.

As a developer, how do you add an automated check for software updates to your application? You could use DNS! DNS is lightweight, provides redundancy, responses are cacheable, and going through your network resolver gives you some privacy.

But, making DNS changes as part of a software release is not ideal, I've done it. Can we automate this? We can for Go applications! Gopherwatch.org is a free service that monitors the Go sumdb, a transparency log (like certificate transparency) containing all Go "modules" (libraries/applications) and their published versions. Gopherwatch.org provides a DNS interface for querying the latest version for all Go applications/libraries, and the latest Go toolchains.

We'll look at how the Gopherwatch DNS interface works and discuss limitations and possible future improvements. If there's time, we'll also look at how the DNS interface is used to provide one-click or even fully automated software updates for Go services.

Digital Workplaces increasingly consolidate collaborative tools, yet telephony often remains isolated and difficult to integrate. User needs show that a unified interface, including VoIP, simplifies the user experience while reducing vendors and costs. Once treated as a silo, telephony is now starting to become a central component of collaborative platforms.

This presentation will cover the key technical integration points for adding a a softphone application and a VoIP calling service to a Digital Workplace: embedding a web-based calling client into an existing interface, managing SSO and account provisioning, unifying call histories and presence information, ensuring interoperability between system notifications and platform notifications, and adapting the user interface.

We will illustrate these points with a concrete example using the SIP client Linphone and the SIP server Flexisip, demonstrating how an open source VoIP solution can be technically integrated into a collaborative platform: adapting WebRTC to SIP, handling push notifications for incoming calls, retrieving call logs via an API, and more.

The goal is to show how telephony can become a modular building block for collaboration rather than an isolated tool, and why this approach is essential for open source Digital Workplaces like Nextcloud, OpenDesk, or eXo Platform to offer a complete solution. It is only by combining the strengths of different specialized open-source software editors that it may be possible to compete with major players in the collaborative-software market, such as Microsoft 365.

In 2020, a group of friends and I started a Luanti minigames server called "A.E.S.". One of the aspects that fascinated us about Luanti was being able to provide translated content according to the language set on the client - even for online servers. What we didn't know was that, we can't really ask translators to learn git if they want to contribute. Having a tailor-made translation format didn't help either. Fast forward of a few years and, thanks to Codeberg staff, we migrate to Weblate; which is when the boom of translations happened. A.E.S. now features 14 languages and, with Luanti switching to an industry standard (.pot/.po files), life becomes even easier. People can now play their favourite games without having to struggle with a language they might not know -so as to focus on the game itself.

The new Collabora Office brings a beautiful, ergonomic suite, based on LibreOffice to the desktop. Come hear why, in 2026 we're creating a native local application. Hear about the limitations of Web APIs, and checkout some of the metrics we have gathered around how people collaborate on-line, and the engineering decisions that flow from that. Hear about our new approaches to handle collaboration, off-line, conflicts, and forthcoming protocol to negotiate transitions between co-editing, sharing, on-line and off-line. Finally catch up with the latest in UX research, interoperabiltiy and feature improvements as well as seeing how to get involved with the project.
