Initialization of all elements of an array to one default value in C++?
... C++, to set them all to -1, you can use something like std::fill_n (from <algorithm>):
std::fill_n(array, 100, -1);
In portable C, you have to roll your own loop. There are compiler-extensions or you can depend on implementation-defined behavior as a shortcut if that's acceptable.

C# Lambda expressions: Why should I use them?
...executed. An API just has to make a delegate parameter into an Expression<T> parameter and the compiler will generate an expression tree from a lambda instead of an anonymous delegate:
void Example(Predicate<int> aDelegate);

How to identify numpy types in python?
...
Use the builtin type function to get the type, then you can use the __module__ property to find out where it was defined:
>>> import numpy as np
a = np.array([1, 2, 3])
>>> type(a)
<type 'numpy.ndarray'>
>>...
Func vs. Action vs. Predicate [duplicate]
...- for example in projections:
list.Select(x => x.SomeProperty)
or filtering:
list.Where(x => x.SomeValue == someOtherValue)
or key selection:
list.Join(otherList, x => x.FirstKey, y => y.SecondKey, ...)
Action is more commonly used for things like List<T>.ForEach: execu...
