What does principal end of an association means in 1:1 relationship in Entity framework
...is. I've come to find out that EF to this day has never implemented unique indexes. As a result, the only way available to map a one-to-one is to use the primary key of the principal end as the primary key of the dependent end, because a primary key is by nature unique. In other words, they half-imp...

Differences between Agda and Idris
...the easiest example is associativity of vector concatenation. Given length-indexed lists called vectors defined thusly:
data Vect : Nat -> Type -> Type where
Nil : Vect 0 a
(::) : a -> Vect n a -> Vect (S n) a
and concatenation with the following type:
(++) : Vect n a -> Vect...
Python : List of dict, if exists increment a dict value, if not append a new dict
...really have to store the visited urls as a LIST?
If you sort it as a dict, indexed by url string, for example, it would be way cleaner:
urls = {'http://www.google.fr/': dict(url='http://www.google.fr/', nbr=1)}

if url in urls:
urls[url]['nbr'] += 1
else:

Views are "pseudo-set-like", in that they don't support indexing, so what you can do with them is test for membership and iterate over them (because keys are hashable and unique, the keys and items views are more "set-like" in that they don't contain duplicates).
You can store the...

Therefore, it is not necessary to declare a method virtual in order for that method to implement an interface method - the global interface m...
