Foreign Key to multiple tables
...
You have a few options, all varying in "correctness" and ease of use. As always, the right design depends on your needs.
You could simply create two columns in Ticket, OwnedByUserId and OwnedByGroupId, and have nullable Foreign Keys to each table....
Passing a std::array of unknown size to a function
...way to make this work, as one would with plain C-style arrays?
No. You really cannot do that unless you make your function a function template (or use another sort of container, like an std::vector, as suggested in the comments to the question):
template<std::size_t SIZE>
void mulArray(std:...
How can I pass selected row to commandLink inside dataTable or ui:repeat?
...e by @ViewScoped.
Use Application#evaluateExpressionGet() to programmatically evaluate the current #{item}.
public void insert() {
FacesContext context = FacesContext.getCurrentInstance();
Item item = context.getApplication().evaluateExpressionGet(context, "#{item}", Item.class);

Understanding the difference between Object.create() and new SomeFunction()
...
The object used in Object.create actually forms the prototype of the new object, where as in the new Function() form the declared properties/functions do not form the prototype.
Yes, Object.create builds an object that inherits directly from the one passed as ...
Is there a way to instantiate objects from a string holding their class name?
...initializing or assigning to it. Have a look at its documentation here. Finally, the use of a raw function pointer is also a bit oldish. Modern C++ code should be decoupled from specific functions / types. You may want to look into Boost.Function to look for a better way. It would look like this the...

What is the advantage of using forwarding references in range-based for loops?
...or<bool> v(10);
for (auto&& e : v)
e = true;
}
All that being said, I wouldn't code this way unless you knew you needed to satisfy such a use case. I.e. I wouldn't do this gratuitously because it does cause people to wonder what you're up to. And if I did do it, it woul...
What is the “owning side” in an ORM mapping?
...d in the association table PERSON_ID_DOCUMENTS.
On the other hand, if we call idDocument.setPerson(person), we change the foreign key person_id on table ID_DOCUMENTS. Hibernate is creating two unidirectional (foreign key) relations on the database, to implement one bidirectional object relation.
