We have a new partner and a special recommendation for you: The Software Engineering Camp (SWEC) is an open space conference on all things software engineering and craftship! 🤩

Since 2016 the @swec provides the opportunity to learn, socialize and grow with a diverse community of techies and nerds. They want to make the world a better place. They SWEC to differ, because code does not make a difference – but we all do!

@tisba Great feedback, thanks for taking time to share and ask! 🙏🏻 We'll definitely improve this formulation. We meant to refer to last year's edition, aka 2025. Registration for #osco26 is planned to open in July 2026, we'll announce it in time here. Hope to see you there! [lisi]
