Today I start coding on undo/redo for DrGenius, this will bring lot of side effect as scriptability and even using Corba for a distance manipulation of a figure. At mid-day I stop hacking on that thing and try to work on the AI course. It's incredible how in one sheet of paper they can introduce you 10th of new symbols, 10th of definitions and it tooks you one hour to start to figure out these things. This course can make me feel asleep even on the morning, so i let you imagine after a lunch. Finaly I decide I better hacking on drgenius instead of sleeping...
