Personal Thanks
Special thanks to my son, a brilliant programmer, whose sharp critiques and insightful suggestions helped shape the structure, style, and sanity of this site. His encouragement (and cheerful mockery) pushed me to update old habits and adopt better practices. Thanks also to my daughter for her cute drawings and her keen eye for design.
