I spent last week at Oracle's customer event, OpenWorld 2017, in San Francisco. When I wasn't drinking from an information fire hose, it was alternately fascinating and exhausting. There were major announcements in database, blockchain, artificial intelligence, cybersecurity, and other stuff I'm associated with only tangentially. For instance, my eyes glaze over when they start talking about bare metal servers and going serverless, so I'll limit my observations here to database and security, with a few dashes of other things.
