Today is the 81st Anniversary of the 479th Fighter Group attack on the German held airfield at Nancy-Essey aerodrome in Eastern France. Gun camera footage are from my Dad's P-38. Artist's rendition, "Scat Attack", based on this same footage features Dad's fried, Robin Olds.

I'm teaching Refactoring and SOLID Design for Embedded C++ this week, including a rare business trip (travel for me basically died 5 years ago). Being with people will be fun. One of the themes of the course includes the First Law of Holes. When you find yourself in a hole,

I had a good turn out for my Embedded online Conference Keynote. I got some people to join me admitting, "I am a programmer and I write bugs". Will you admit it?. #EOC2025
