I design software, and I write books about software design. My software helps power pretty much every Internet-aware device you use daily - smartphones, ATMs, browsers. My books tend to have consequences and stay interesting for a long time. What I try to do is inquire deeply into timeless design patterns and the mindset that makes for great software When I'm not writing code or books, I'm a science fiction fan, a martial artist, a firearms instructor, and a championship-level strategy gamer. I like Szechuan food, cats, and redheads. I live in Malvern, Pennsylvania with a redheaded wife and a ginger cat. You can read my personal blog at: http://esr.ibiblio.org
