The Automated Testing Summit (ATS) 2025, hosted by KernelCI, is a technical conference focused on the key challenges, tools, and infrastructure involved in testing and quality assurance for the Linux ecosystem — with an emphasis on upstream kernel development, embedded systems, cloud environments and CI integration.

Modern software stacks grow increasingly complex and heterogeneous. Ensuring their stability requires scalable, reproducible, and automated testing solutions that can operate across diverse hardware platforms, kernel versions, and integration layers. ATS brings together engineers working on KernelCI, test frameworks, lab automation, CI/CD pipelines, fuzzing, performance analysis, and more.

The event is a platform for in-depth technical talks, demos, and collaboration sessions that tackle real-world problems in automated testing. Topics range from designing interoperable systems for sharing test results, to debugging kernel regressions across distributed hardware labs.

ATS 2025 is where upstream meets infrastructure — and where collaboration across project and organizational boundaries is essential to advance quality at scale.

CHAOSS is a Linux Foundation project focused on creating metrics, metrics models, and software to better understand open source community health on a global scale. CHAOSS is an acronym for Community Health Analytics in Open Source Software. Open source software is critically important for both individuals and organizations. This importance raises questions about how we understand the health of the open-source projects we rely on. Unhealthy projects can have negative impacts on the community involved in the project as well as organizations that rely on such projects.

At CHAOSSCon, you will learn about open source project health metrics and tools used by open source projects, communities, engineering teams, OSPOs, Universities, and scientific / research software to track and analyze their open source work. This mini-conference will provide a venue for discussing open source project health, CHAOSS updates, use cases, and hands-on activities for developers, community managers, project managers, and anyone interested in measuring open source project health. We will also share insights about the activities happening across the CHAOSS project.

The travel retail industry is evolving to focus on delivering comprehensive experiences rather than just individual services. This shift necessitates enhanced interoperability among travel providers and retailers. Current protocols, rooted in standards from the 1960s, are outdated and insufficient for modern needs. The industry requires a new approach to handle travel offers as digital retail products. Addressing these challenges can unlock significant economic opportunities by automating travel arrangements and providing access to previously excluded suppliers. Following the success of employing open-source practices in solving similar issues, the LF Open Travel Foundation is being formed.
