Open Source Community Governance the Apache Way (Drost-Fromm & Tompkins, IEEE Computer Column)

I’m happy to report that the 14th article in the Open Source Expanded column of IEEE Computer has been published.

TitleOpen Source Community Governance the Apache Way
KeywordsOpen Source Software, Distributed Computing, Documentation
AuthorsIsabel Drost-Fromm, Apache Software Foundation
Rob Tompkins, Apache Software Foundation
PublicationComputer vol. 54, no. 4 (April 2021), pp. 70-75

Abstract: An open source project without the people is a dead project—or at least one that is fairly deep asleep. While all successful open source projects understand that they need to build a community around their project, the exact options for doing so differ.

Research-to-Startup for Postdocs (5min. Video for DAAD PRIME Workshop)

This 5min. video discusses basics of turning your research into a startup. It focuses on public funding. The video was created for the March 2021 DAAD PRIME workshop, but is not restricted to a postdoc audience. Indeed, it works for anyone with a good idea and ideally a team who is willing to move to Germany to benefit from its rich ecosystem for public funding of startups.

Abstract: Free, open source software (FOSS) has a long history, beginning with the origins of software itself, when the terms free software and open source software were not yet defined. Learning about the milestones of this history may help to understand FOSS today.

Interview with GSO on Academia and Entrepreneurship

The German Scholars Organization (GSO) just published an interview with me on how to create startups from research in Germany

How can you spin your research into a startup? We asked Dirk Riehle, professor of Computer Science and advocate for founders with an academic background, for insights and advice. Before becoming a professor, Dirk has worked in industry, always in close connection with startups. His passion for entrepreneurship has become a big part of his professorship and Dirk has been developing, guiding, and supporting startups from research.

Two Types of Open Source Communities

tl;dr The communities that form around community open source are very different from those that form around commercial open source; confuse them at your own risk.


The recent announcement by Elastic to relicense their software away from open source licenses to commercial and source-available licenses only has triggered the debate about rights and expectations of open source communities again (local copy 1, 2, 3).

Legally speaking, I assume that this is fully within Elastic’s rights. I assume they either outright own all copyright to the relicensed code or collected copyrights by way of contributor license agreements from anyone whose code they accepted into their code base.
