Exciting news; people are now working with DCI implementations in Ruby,
Python, Java, C++, Scala, Groovy , and Qi4J. A new mailing list for
implementors has been established:
object-composition - at - googlegroups.com
I have written a commentary on my Squeak implementation of the DCI part
of BabyIDE.
http://heim.ifi.uio.no/~trygver/2008/bb1implementation.pdf
The commentary builds on the "Common Sense" report and is written for
the systems programmer who is interested in the usually hidden innards
of BabyIDE.
Enjoy
