I'm the author of Effective Perl Programming.
I was also known in the mid 1970s as a child prodigy and a survivor of childhood acute lymphoblastic leukemia.
I currently live in the San Francisco Bay Area. In the past, I've lived in Fairbanks, Alaska, Chandler, Arizona (near Phoenix), the Philadelphia area, Nashville, the Research Triangle area, and the Appalachian Mountains in northwestern North Carolina. I've experienced temperatures of 122 degrees Fahrenheit in Chandler and minus 55 Fahrenheit in Fairbanks - a 177 degree range!
