Welcome to my personal web site. It includes my blog, a catalog of useful web sites I've collected over the years, photos I've taken on various trips, links to talks I've given and software I've written, etc.

When I registered this domain in the previous millenium, it was already hard to find a good domain name. I chose speechcode.com because of the speech code in the novels of Adam Hall, one of my favorite spy authors. Since then, another meaning of the term has become common. I certainly didn't, and don't, intend any association with that idea.

My favorite programming language is Scheme, which is a dialect of Lisp. It's simple, elegant, and powerful, and there are several excellent implementations of it, including Chez Scheme, Chibi, GNU Guile, MIT/GNU Scheme, Racket, and Scsh. I am editor of SRFI, the Scheme Requests for Implementation, a standards process for Scheme that started in 1998.

For the sake of nostalgia, I'm hosting an old version of the Jargon File.

Thank you for visiting.
