The vulnerability was patched by Alex Peshkov. All Firebird binaries released with build numbers or lower and all snapshot builds before For more information, refer to this topic. This correction will impact code that called those functions on big-Endian hosts in Firebird 2.
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.

Leone, I don't know that I can help you all that much. It definitely sounds like a permissions problem. We have a "reviewboard" group that we put everyone that needs access to certain files into that group.
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. The important takeaway is that none of these modeling schools is "better" than its peers.
Each one can model essentially any problem. There are tradeoffs involved with each school, by definition — otherwise all but one would have disappeared by now.
Finding the sweet spot Sometimes it makes sense to use multiple modeling techniques in the same problem space. Choosing the right technique comes down to convenience. For any given real-world problem, one or two modeling schools are likely to be the most convenient approaches.Download-Theses Mercredi 10 juin Oct 20, · Note: Today's entry is a technical article: it isn't funny.
