Chi siamo
The association guild42 organizes events in Bern on topics from the field of software development:
- Programming languages
- Frameworks and libraries
- Tools and platforms
- Patterns
- Methodologies
- Project management
- Application and software architecture
The focus is on the exchange of knowledge and experience among software developers and software development companies, but also on fostering personal connections.
Through this initiative, we hope to increase the attractiveness of Bern as a location for software developers and software development companies.

Free/Libre Software & Freedom, touching on how they relate to Machine Learning
Berner Fachhochschule Wirtschaft, Brückenstrasse 73, Bern, CHAbout the Event
Richard Stallman gives as an insight of is ideas and work on Free Software and it's impact on our every day live, becoming more and more digital.He will give an explanation of the issues of justice and injustice in distribution and running of software, and in use of computing services and dis-services, with discussion of how this relates to machine learning, including both Artificial
Intelligence and Pretend Intelligence.The talk will be held in English. There will be a small apéro after the talk.
If your interested in merchandise such as cool stickers please bring cash to support the Free Software Foundation!
Speaker
Richard Stallman is the founder of the Free Software Movement and a prominent advocate for software freedom. He has been a key figure in the development of free software and has influenced the technology landscape significantly through his work on the GNU Project and the Free Software Foundation.

Supply Chain Security
Aula at PROGR, Speichergasse 4, Aula, Bern, CHBuilt Fast, Poorly Protected? Supply Chain Security Between Container Convenience and the CRA (Cyber Resilience Act).
Abstract
Over the past few years, security efforts have focused primarily on cloud infrastructure and on preventing or remediating misconfigurations. In modern software development, however, the security of container images is often treated as a secondary concern, with speed of development and convenience taking precedence. Existing components, from libraries to base images, are reused and sourced through complex and opaque supply chains.
Following prominent security incidents such as Log4j and xz, supply chain security has increasingly moved into the spotlight. In 2025, supply chain failures ranked third for the first time in the OWASP Top 10 Critical Security Risks to Web Applications.
The EU’s Cyber Resilience Act (also applicable in Switzerland) will, starting in 2026, introduce binding requirements to promptly remediate actively exploitable vulnerabilities and to provide complete Software Bills of Materials (SBOMs).
In this session, we will explore solutions for making software supply chains more secure in the future while simultaneously meeting the requirements of the CRA.The talk will be held in German with some Bernese sprinkled in.

Java Strikes Back: Engineering the Agentic Era
Aula at PROGR, Speichergasse 4, Aula, Bern, CHAbstract
AI systems are moving beyond prompts to agents that plan, act and interact. And this time, Java is not catching up, it’s leading. Frameworks like LangChain4j and Embabel bring agentic capabilities with the strengths Java is built on: type safety, structure, reliability and testability.
Agents aren’t a passing hype. They are a necessary design pattern for robust AI systems, enforcing separation of concerns, controlled execution flows and human-in-the-loop checkpoints. They make complex AI interactions predictable, auditable and production ready.
This talk shows how the Java ecosystem is turning agentic design into a disciplined engineering approach, and how you can start replacing suitable parts of your processes using agents in a practical, production-ready way.The talk will be held in English!
Speaker bio
Lize Raes loves helping developers to bring AI into real-world applications. As Developer Advocate for Java + AI at Oracle and collaborator at LangChain4j, she’s invested into making cutting-edge tech accessible and useful for developers. Her path has taken her from cochlear implant research to advising the Belgian government during COVID-19, to bioinformatics for drug development. Lize likes her projects hands-on and slightly unconventional, especially when they help make the world a bit better. Outside of work, you’ll find her behind the piano or in her woodworking atelier.Sponsors ans patrons
