The Open Source Journey

• Amanda Brock (OpenUK)

Room: 503/1-001 - Council Chamber This talk will be a brief exploration of what open source is, why has it gained such phenomenal success in the last decade and what does this mean for open source? Why do both the private and public sector turn to it in our digitalised environments? In a world of AI, geopolitics and Sovereignty what are the challenges and where does open source fit? The audience will leave with a better understanding of open source today and the challenges it faces. --- OpenUK CEO and Executive Producer State of Open Con, Amanda’s 25 years’ legal experience includes being instrumental in shaping open source’s legal frameworks and internet law in 2000’s.

Investing in the infrastructure of the 21st century

• Adriana Groh (Sovereign Tech Agency)

Room: 503/1-001 - Council Chamber Every modern digital technology—from AI to quantum computing—is built on open source software. When you send an encrypted email, collaborate on a document, or run a Python script, you're using foundational open source components. While open technologies have become the backbone of our digital infrastructure, these essential building blocks do not receive adequate support, investment, or even recognition. The Sovereign Tech Agency addresses this through strategic public investment in the digital infrastructure of the 21st century. We focus on the essential building blocks that enable all software creation: programming language libraries, package managers, open communication protocols, developer tools, and encryption. This talk will introduce the Sovereign Tech Agency and the programs it has developed to support these critical technologies: the Sovereign Tech Fund, which commissions work on critical open source components; the Sovereign Tech Fellowship, which provides effective support to essential maintainers; and the Sovereign Tech Resilience program, which takes a holistic approach to the security and stability of foundational technologies. These efforts ensure that individuals, organizations, companies, and governments have real choice and technological autonomy in an increasingly digital world.

Empowering Public Sector Digital Sovereignty with Open Source

• Leonhard Kugler (ZenDiS)

Room: 503/1-001 - Council Chamber ZenDiS - the German Centre for Digital Sovereignty - supports the public sector in building digital sovereignty through open-source solutions. This talk outlines how the openCode platform enables collaborative software development and sharing across public institutions, while openDesk provides an open, flexible workspace solution based on that shared code. Together, these initiatives demonstrate how coordinated open-source development can strengthen secure software supply chains, ensuring reliability and trust in the digital tools used by governments.
