brainbench Design Patterns certification ...

Hello all,

I was trying to score in the Design Patterns brainbench certification
just to make sure I got all concepts OK but unfortunately I underscored
because despite I had strong knowlege of the GoF patterns (all GoF
patterns answered correctly) but not so the "language-specific patterns"
.... for which I did not know almost any ... is there any exhaustive
reference
of language-specific design patterns e.g.

- "Null Object Design Pattern"
- "Immutable Pattern" => Read-Only Pattern

Is this becoming an uncontrolled exploding born of Patterns?
who guarantees that all are correct? are all these emerging
patterns standarized? controlled? tested? de-duplicated?
so everyone know them and can refer to them univocally?

I just have a new pattern in mind the "Pluggable Obj" in C++
where can new Design Patterns be unambiguously registered?

Best Regards,
Giovanni

I agree.

I feel the move from building desktop apps (where gof has a predominant
impact) to enterprise level apps is yeilding to new areas in patterns.

I think there has been lot of work on Enterprise level patterns which
in turn (might use a mix of gof patterns)... For example, the J2EE
servlet filter design pattern ( to manipulate a HTTP response ) is a
gof decorator pattern....

Not to my knowledge.

There are lots of books with titles like _XXX_Design_Patterns_, _Design_
_Patterns_in_XXX_, and _Design_Patterns_for_XXX_. Some of them might even be
good :-).

I'm not familiar with the "brainbench certification" test that you described
previously. If it's an industry certification, I would expect the testing
company to tell you what material you should study.

I don't think that the field is "exploding," but people certainly have
published a lot of work about patterns since the GoF book.

Nobody guarantees that patterns are "correct," "standardized," or "controlled."
Perhaps I should say that, to the extent that any of these things are done, it
is the community that does them. One would also hope that the community
ensures that patterns are "tested" --- part of the identification of a pattern
is documenting previous known uses --- and "de-duplicated."

Giovanni> I just have a new pattern in mind the "Pluggable Obj" in C++

There is no such registry. If you want feedback from the community, you might
consider participating in one of the many PLoP conferences.

Best wishes ---
