Object Conversions in Type Hierarchies (Presentation)
Here are the slides from a short presentation, longer "chaulk talk" and then discussion session that I did at Santa Fe Institute. For most, this topic is probably a real snoozer. But I've been interested in this every since I used to teach a course for Rational Software and one of the lessons was on the "cost of metamorphasis" as it applies to software (not insects!). You can view and download the slides [here].
