The guy in the article does have some cred. He was a professor at UC Berkeley for 29 years where he was project leader on Ingres and led the creation of its follow up, Postgres.
His new database, VoltDB, based on the 'NewSQL' ideas touched on in the article, is Free Software licensed under the GPLv3.
