I had a taste of Prolog in college and always wanted to learn more, especially after reading this Dr. Dobb's article about using it for a vaccine scheduling app: http://www.drdobbs.com/database/building-a-custom-rule-engine-with-prolo/184405583 http://www.drdobbs.com/database/building-a-custom-rule-engin... With all the interest these days in DSLs, I feel like knowing when/how to embed Prolog into larger applications could be a great tool in my toolbox.
