  • ... I'm still not totall clear about this roles nonsense :-) :-)

    • I knew someone would bring that up :)

      Roles are shared behavior with methods which can't conflict. It's tough to get any simpler than that.

      • I'm partially kidding :-)

        I don't really buy your law though. It was tough for me to "get" roles for various reasons. It was tough for me to get declarative Prolog-ish languages when I first encountered them. I know a bunch of people who took a hell of a time to understand OO. I know a bunch of folk who don't really "get" TDD, XP or Scrum.

        Yes - there are nice sound bites for all of them. But they don't really "explain". The concepts are often deep - even if they have a simple container.

        • The actual law should read (and I knew this when I posted my rather hyperbolic comment): "the more difficult it is to explain a technology which aims to "improve" software, the more likely it is that that this technology fails in its goals. Not quite as catchy, though :)

          See Aspect-oriented programming [wikipedia.org] for a great example. What's a "pointcut"? What's a "join point"? What's "advice"? Why is "advice" described as "additional behavior"? "Advice", to me, reads "optional behavior". And does AOP require spe

            Aspect-oriented programming is used to concisely implement cross-cutting concerns across a high number of classes and methods that would otherwise require immense quantities of hard-to-maintain code spread out over your whole application.

            Examples of cross-cutting concerns which are very amenable to Aspect techniques include logging, debugging and performance monitoring.

            • So what's a "pointcut"? What's a "join point"? Do you really need a custom IDE to use AOP or not? (I've heard both ways)
