As both a sponsor and active participant in the Adoptium Working Group, OpenElements demonstrates how even small teams can make a meaningful impact on open source sustainability.
The conference focuses on presenting new and unique results in the field of mobility simulation and modelling using openly available tools and data. We expect a large variety of research topics and usage approaches. Possible areas of interest include (but are not limited to):
The TheiaCon 2025 keynote provides a comprehensive update on a breakthrough year for the Eclipse Theia ecosystem, including major AI, platform, and architecture enhancements. A great overview for anyone interested in modern, open, AI-native tooling. The recording is now available!
Running a successful open source project requires investment, clear goals, and adherence to core principles like transparency, openness, and meritocracy.
Code editors are up for grabs, and the Eclipse Foundation is supporting this innovation and choice.
For the Theia community, this is a meaningful milestone. It confirms something many of us already felt simply by watching adoption: this project is becoming one of the most exciting developments in the open source dev tooling landscape!
The “Open Source Stewards and the Cyber Resilience Act” white paper explores a new role introduced by the EU Cyber Resilience Act (CRA): the open source steward. This is a newly introduced actor that doesn’t fit neatly into the existing categories of manufacturers or distributors but still carries specific obligations under the CRA.
