Welcome to The Craft of Open Source, hosted by Ben Rometsch, Co-Founder and CEO of Flagsmith. This bi-weekly show is focused on the ins and outs of the Open Source Software Community. Join Ben as he speaks with the brightest minds that have brought us some of the most adopted technologies on earth. Each episode is an interview with creators, maintainers, entrepreneurs, and key contributors to the open source community.
We will cover critical topics for open source developers, contributors and entrepreneurs such as: Which open source licenses are best if you want to start a business at some point? How did people start their projects? What was the first commit? Did people start their projects for business or a different reason? How can you build an organic community around new projects? How can you create a business and still be open source? Where is open source headed?
The technologies that we plan to profile will range from huge projects like React.js, Ansible, Git, PHP, Kafka, GitHub, Java, Python, Javascript, Redis, Kubernetes, VisualStudio, TensorFlow, Android, Apache, Spinnaker, Azure, and many more.
The types of licenses that we plan to profile will include: GNU General Public License (GPL), The Apache License, Microsoft Public License (Ms-Pl), Berkeley Software Distribution (BSD), Common Development and Distribution License (CDDL), Eclipse Public License (EPL), and MIT License.
