  • Bayes sans equations and tears

    George Rebane This little monograph is the most recent in the series to explain Bayesian reasoning to the non-technical (but otherwise intelligent) reader, and will serve as a reference for future posts.  Some previous efforts in this direction can be found here and here.   In the sequel we repeat the exercise graphically without resorting to…

  • Still wrong about liberal arts majors

    George Rebane Political science major and entrepreneur David Kalt writes ‘Why I Was Wrong About Liberal-Arts Majors’ in the 1jun16 WSJ.  There he argues from his experience that it’s really the liberal arts majors –  philosophy, history, music, … – who have the best background to become what he knows as “computer programmers”.  Why?  Because…

  • Preventable Global Warming is a Tricky Business (updated 23sep15)

    George Rebane [Brian Hamilton, editor of The Union, emailed me that this piece was bit too long for their Other Voices columns, and invited me to shorten it.  I felt that a better alternative to abbreviation was to write them a letter-to-editor that cited Mr Paul Berger’s dismissal of my previous OV column, and which…

  • Scattershots – 22jun15 (updated 27jun15)

    George Rebane Economic development in Nevada County must address what many of us see as the three legs of the county’s existing economy – IT based industry, tourism, and retirees.  Absent public service employees, these are the three main cash importers.  There are initiatives in place to attract more IT companies through increased broadband availability…

  • …, and this too shall pass

    George Rebane Bet you thought I was going to wax eloquent on some deep philosophical or socio-political issue, a behavior for which I have a weakness as witnessed numerous times in these pages.  Fooled you.  In another life I am currently working on a couple of very intriguing technical projects involving uncertainty and algorithmics, the…
