David Cramer joined the show to talk about the recent license change of Sentry to the Business Source License from a BSD 3-clause license. We talk about the details that triggered this change, the specifics of the BSL license and its required parameters, the threat to commercial open source products like Sentry, his concerns for the “open core” model, and what the future of open source might look like in light of protections-oriented source-available licenses like the BSL becoming more common.

Robert C. Martin, aka Uncle Bob, joined the show to talk about the practices of Agile. Bob has written a series of books in order to pass down the wisdom he’s gained over his 50 year software career — books like Clean Architecture, Clean Code, The Clean Coder, The Software Craftsman, and finally Clean Agile — which is the focus of today’s discussion. We cover the origins of his “Uncle Bob” nickname, the Agile Manifesto, why Agile is best suited for developing software, how it applies today, communication patterns for teams, co-location vs distributed, and more importantly Bob shares his “why” for writing this book.
