If none of the styles are hidden and at least one of them is not none, then narrow borders are discarded in favor of wider ones. […]
If border styles differ only in color, […]

URL encoding the space character: + or %20?
...reats them as %20.

C# Interfaces. Implicit implementation versus Explicit implementation
...situation (rather more common) that requires explicit implementation of at least one interface member is implementing multiple interfaces that have members with the same signature but different return types. This can happen because of interface inheritance, as it does with IEnumerator<T>.Curr...
Simple proof that GUID is not unique [closed]
...If you generate a sequence of n GUIDs randomly, then the probability of at least one collision is approximately p(n) = 1 - exp(-n^2 / 2 * 2^128) (this is the birthday problem with the number of possible birthdays being 2^128).
