This Thursday (February 11th, 14:00 UTC), Seppo Jaakola & Alex Yurchenko will talk about MySQL Galera Multi-Master Replication. Galera provides synchronous multi-master replication and uses a certification-based replication method for replicating transaction write sets in a DBMS cluster. The replication method requires close co-operation with database transaction processing and DMBS must support a specific replication API to be compatible with Galera. Codership has integrated Galera replication in the InnoDB storage engine, and the resulting MySQL/Galera cluster product has been published as a production-ready GA release in December 2009. The MySQL/Galera release 0.7 is available on the Codership and …

One of the issues I have with the Free Software approach is that advocates have habit of throwing the baby out with the bathwater when discussing issues that they see as in any way negative to free software.

I was reminded of this while reading Bradley M. Kuhn’s criticism of Mark Shuttleworth’s reported views on copyright assignment.

Having read the original interview with Mark, and then Bradley’s response, it is pretty clear that the two have very different perspectives on copyright assignment: Mark is speaking from the perspective of a commercial business, Bradley form that of a non-profit foundation.

The two entities have very different reasons for enforcing copyright assignment …
