Relationship between SciPy and NumPy
... contain nothing but the array data type and
the most basic operations: indexing, sorting, reshaping, basic
elementwise functions, et cetera. All numerical code would reside in
SciPy. However, one of NumPy’s important goals is compatibility, so NumPy
tries to retain all features supported...

Is there a way to instantiate objects from a string holding their class name?
...ble: http://www.boost.org/doc/libs/1_54_0/libs/functional/factory/doc/html/index.html
My preference though is to generate wrapper classes which hide the mapping and object creation mechanism. The common scenario I encounter is the need to map different derived classes of some base class to keys, wh...
List or IList [closed]
... that can be addressed the same way as a linear array T[] using an integer index. When you specify IList<T> as the type of the method's argument, you only specify that you need certain capabilities of the container.
For example, the interface specification does not enforce a specific data st...
Why Func instead of Predicate?
...;T>, Func<T, int, bool>)
That allows you to filter based on the index of the entry as well. That's nice and consistent, whereas:
Where<T>(IEnumerable<T>, Predicate<T>)
Where<T>(IEnumerable<T>, Func<T, int, bool>)
wouldn't be.

Under what circumstances are linked lists useful?
...hash and nodes of chains are kept in it. There is also a free pointer - an index into the array - that follows deletes. ;-) So - believe it or not - the FORTRAN technique still lives on. (...and nowhere else, than in one of the most commonly used .NET data structures ;-).
