Kevlin Henney - Paradigms Lost, Paradigms Regained: Programming with Objects and Functions and More

It is very easy to get stuck in one way of doing things. This is as true of programming as it is of life. Although a programming paradigm represents a set of stylistic choices, it is much more than this: programming also represents a way of thinking. Having only one way to think about problems is too limiting. A programming paradigm represents a set of patterns of problem framing and solving and contains the ingredients of software architecture. As Émile Auguste Chartier noted, there is nothing more dangerous than an idea when you have only one idea.

Perhaps even more problematic than being stuck with a narrow view of paradigms is being stuck with a dysfunctional view of each paradigm. For instance, many developers working in languages and frameworks that support object orientation have a strong idea of the principles of interaction, data abstraction, and granularity that support an effective view of OO, and instead surround themselves with manager objects, singletons, and DTOs.

During the day we will explore the strengths and weaknesses of different programming styles, patterns, paradigms, languages, etc., with examples and opportunities for discussion.
