  • Conflict of interest in open source and PostgreSQL replication

    Conflict of interest in open source and PostgreSQL replication

    Community open source is open source that is not owned by any particular company. Rather, ownership is shared among a large number of diverse stakeholders. Given the right (read: permissive) license, commercial companies can provide extensions to the community project, earning a living. Since such extensions are a unique selling point of these companies, one…

  • Open source is a business strategy not a business model

    Open source is a business strategy not a business model

    Following up on related discussions, another common confusion in my opinion is to think that “open source” is a business model. It is not.

  • Commercial, professional, and community open source: Resolving the naming confusion

    Commercial, professional, and community open source: Resolving the naming confusion

    As a researcher, imprecise naming bothers me. The general confusion around the terms commercial open source, professional open source, and community open source warrants closer analysis. First my proposal, then some litmus tests, followed by a bit of history. Commercial open source is software provided as open source where a single legal entity owns the…
