homological algebra - How to construct a ring with global dimension m and weak dimension n?

If $R$ is Noetherian then they are equal.

For $n=0$ one can use the fact that any Boolean ring has weak dimension $0$ (any module is flat), but a free Boolean ring on $aleph_n$ generators have global dimension $n+1$, see the last paragraph of this paper.

For any given pair of $(m,n)$ one can perhaps use polynomial rings over the examples for $n=0$ case (The global dimensions do go up properly, but the behavior of weak dimensions seem to be trickier, may be someone who is a real expert can confirm this?)
