A transparency-first community event

We believe that the community and the open-source models are well suited for our core values: learning, teaching and knowledge sharing. Our mission is to inspire other communities with the concept of open-source events.

We’re publishing all data about this conference, in full transparency. We are also available at any time for inquires and we’re really looking forward to sharing our knowledge about organizing international events. This way, whenever a community wants to start something similar, they can build on our knowledge.

    Talk: The code etymologist

    In ancient times, knowledge was passed down through word of mouth, like an endless game of telephone where details changed with each retelling. Without a written record, information was often distorted or lost. This talk draws a parallel to software teams that work without documentation. Just like etymology traces the origins of words, documentation preserves history, accuracy, and meaning in code, ensuring that everyone shares a common understanding.
