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.
This week we talk with Manish Jain about Dgraph, graph databases, and licensing and re-licensing woes. Manish is the creator and founder Dgraph and we talked through all the details. We covered what a graph database is, the uses of a graph database, and how and when to choose a graph database over a relational database. We also talked through the hard subject of licensing/re-licensing. In this case, Dgraph has had to change their license a few times to maintain their focus on adoption while respecting the core ideas around what open source really means to developers.
