Mark Watson wrote to me about an announcement he made today on his blog:
I ... got back to my Common Lisp “roots” last week when I was enjoying playing with the mocl Common Lisp system for Android and iOS development. I wrote an AI book using Common Lisp for Springer-Verlag in the 1980s, which was lots of fun, and in 2007 I put together a very short PDF free “book” called “Loving Lisp, or the Savvy Programmer’s Secret Weapon” with the help of many people in the Common Lisp community who offered corrections and suggestions. A few years ago I spent a weekend correcting and adding material to “Loving Lisp, or the Savvy Programmer’s Secret Weapon” but I never published the new material. I just decided last night to spend some of my free time updating this book adding more material on: accessing PostgreSQL, MongoDB and CouchDB; writing web apps; a native Common Lisp SPARQL client and some ideas for using SPARQL endpoints in Common Lisp applications, and some general material on information gathering. Basically, supporting an old language like Common Lisp with some fun modern application examples.
