  • BIND9 Adopts the MPL 2.0 License with BIND 9.11.0

In December we announced we were changing the license for our Kea DHCP server to the modern and widely-used Mozilla Public License (MPL 2.0).

  • Resolve to become more of a contributor, less of a free-loader, in 2016

    Do you work for an open-source Freeloader? This week is a great time to assess what open source your organization uses, and make sure you are doing ‘your share’ to support these community resources.
