Most of my writing is about software engineering, although I began life with a PhD in organic chemistry (okay, I really began as a small child). I've written many articles and 13 books on software, project management, product design, consulting, a memoir of life lessons, and even a forensic mystery novel, The Reconstruction. My lates book is Software Development Pearls, with 60 lessons I've learned about software since I began programming in college in 1970. Guitars, recording songs, wine, military history, and volunteering fill in the time between books and articles.
