This is Dave Edstrom's personal blog called Photons and Electrons. This blog is about technology, as well as some of my personal interests. I am the CEO/CTO of Virtual Photons Electrons. I was the CTO for MEMEX for three years, the President and Chairman of the Board for the MTConnect Institute from May 2010 to January 2014 and prior to that I spent 23 years at Sun Microsystems.
