Happy New Year! Even as 2016 was winding down, I found myself with a challenge dealing with time. And I thought I’d share some of my thoughts about a possible approach. Here’s the challenge: You have a database with transactional data, that is data where the rows are inserted, updated and deleted based on events. […]Continue Reading... 2 Comments.

Ever since Noah Salvaterra raised the possibility that Tableau could become self aware, I’ve been unable to sleep. The thought of sentient machines is unsettling.
