Hi. My name is Stefano De Vuono (he/him). I'm sometimes a San Francisco-based and sometimes Earth-based software engineer. I've often straddled the line between art and technology, design and code.

Wouter Tebbens is an industrial engineer born and raised in The Netherlands working from Barcelona. He works for a knowledge society based in human freedom, solidarity, care and regeneration through commons-cooperative networks. He has co-founded and participates in various cooperatives and social organisations.

In the 2000s he set up the Free/Libre and Open Source working group of the Internet Society Netherlands, co-founded the Free Knowledge Institute and coordinated two European Commission funded projects: the SELF project and the Free Technology Academy and participated in various others.
