" if the nonce range is small enough (I think less than 2^248?), it is trivial to derive a solution for the private key"

how we can derive a solution for the private key in this example? I have no idea

I wrote some equations for the private key which you can view here. In particular, the first one which calculates the private key from r, s, and z (in the post it's called h) will be useful.

What is the range of the nonce used in your example, since if the nonce range is small enough (I think less than 2^248?), it is trivial to derive a solution for the private key.
