Allan Crossman calls parapsychology the control group for science.

I hope to offer a different and richer perspective here. With luck, this article might even help begin the process making the Properties Pattern somewhat fashionable again. I should point out that none of these techniques is tied to "static typing" or "dynamic typing" per se.

Each of these modeling techniques can be used with or without static checking. The modeling problem is orthogonal to static typing, so regardless of your feelings about static checking, you should recognize the intrinsic value in each of these techniques.

Class Modeling You know all about this one. Class-based OO design is the pound gorilla of domain modeling these days.

It can take a little practice at first, but for most people class modeling quickly becomes second nature. This is because OO design has no real mathematical foundation to support it — at least, not until someone comes along and creates a formal model for side effects.

The concepts of OOP stem not from mathematics but from fuzzy intuition. This in some sense explains its popularity, and it also explains why OOP has so many subtly different flavors in practice: Industry folks can never quite agree on what OOP is, but we love it all the same.

Relational Modeling Relational database modeling is a bit harder and takes more practice, because its strength stems from its mathematical foundation. Relational modeling can be intuitive, depending on the problem domain, but most people would agree that it is not necessarily so: Object modeling and relational modeling produce very different designs, each with its strengths and weaknesses, and one of the trickiest problems we face in our industry has always been the object-relational mapping ORM problem.

Those who know better know just how hard ORM is in real-world production schemas and systems. Usually XML is used to model data, but it can also be used to model code. I mention this not to start a fight, but only to illustrate that XML is a third modeling technique in its own right.

It has both natural resonances and surfaces of friction with both relational design and OO design, as one might expect. Two other obvious candidates are Functional modeling in the sense of Functional Programming, with roots in the lambda calculus and Prolog-style logical modeling.

Both are mature problem-modeling strategies, each with its pros and cons, and each having varying degrees of overlap with other strategies. And there are still other schools, perhaps dozens of them.Chris Becke • March 15, AM.

The man in the middle attack should be simple enough to mitigate if the two channel authentication is used.

I mean, some client side java could treat the SMS value as a secret value that now the bank, and customer knows, but the attacker does not.

If some of the weirder psi suppression theories are right, psi should actually be easier to study by conducting personal experiments than by trying to study or do public science, especially if you precommit yourself to not telling anyone about the results.
