For example- URL: http://www.imdb.com Keywords: search, movies, movie-index, reviews The keywords themselves are not restricted by number.

I have just read an article about the Curiously Recurring Template Pattern. And you can use it simulate virtual function with templates. For example: template<class T> struct A { void func() { static_cast<T*>(this)->func(); } }; struct B : public A<B> { void func() { cout << "B" << endl; } };` However, if we have many subcla...

Some of my classes should be treated differently. Which solution is better: Introduce new interface to my class hierarchy and check whether the class implements it or not, using RTTI (runtime time identification) Add a method which returns boolean value that indicates whether this class should be treated normally or deserves special tr...
I have the following problem in a Visual C++ 9 program. There's a huge object that logically contains several subobjects. I can either store the subobjects inside the object or store pointers to subobjects allocated separately. The key point here is that there's always one instance of suboject of each type in one outer object - it is al...
As time goes on people are finding smaller, more efficient ways to do things. I'm really impressed at some of the amazing things people have made that are so incredibly simple. Our quest for "a better wheel" has lead to things like a 3Kb javascript framework, a 1kB ORM, a tweet sized framework & DI container, an entire forum in 1kb, a 9...

I am not as familiar with Java's exception packages as with those of .NET. I'm in a situation where, if programming in C#, I would throw a System.InvalidOperationException. Before creating my own java.lang.RuntimeException subclass, I need to know if there is a similar exception type I should throw in Java. The exact scenario is: My ...
Fluent APIs are very common these days. Lately, I'm finding them in almost every system I work with. Mostly, they enhance readability but sometimes they lock me in to inflexible specifications, making understanding the runtime behavior of the specification that they build almost impossible. Is there a consensus on how to create a good fl...
