Retrieving the value of pos0 is straight forward:
Retrieving an element of the map is harder. The position of an element in the map is calculated with:
This means to retrieve the storage on pos1["0x391694e7e0b0cce554cb130d723a9d27458f9298"] we need to calculate the position with:
The geth console which comes with the web3 library can be used to make the calculation:

The sign method calculates an Ethereum specific signature with: sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))).
By adding a prefix to the message makes the calculated signature recognisable as an Ethereum specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.
Note the address to sign with must be unlocked.
