Hi Dan, You made me very happy when you made it to my talk on Thursday. It was impossible for me to present a new paradigm in less than 30 minutes, but I hope I triggered your curiosity. I think your best next step would be to read my article on the DCI Execution model http://fulloo.info/Documents/DCIExecutionModel-2.1.pdf (I hope you will put me right where I have misunderstood something.) The simplest possible example that illustrates the DCI concepts is /BB5BankTransfer/. You can run it and browse its code in my current DCI Squeak image http://fulloo.info/Downloads/BabyIDE-3.zip It would be great if we could do serious work on a realization of the Dynabook dream together. Pharo may be a good starting point because its community seems very open to new ideas. Cheers --Trygve PS. The BabyIDE is an application browser rather than a class browser. There is a kind of user manual embedded in this old article http://fulloo.info/Documents/200904commonsense.pdf PPS. I stick to a very old image because I cannot as yet file out DCI Contexts and role methods. Bootstrap to a better image is therefore impracticable.
