I informed a customer yesterday that it was not possible to name his new server “BOB_BOB” because, for technical reasons, Microsoft operating systems do not allow for the use of palindromic names with an odd number of characters.

    ”This is why,” I told him, “you have never seen a Microsoft Exchange server named ‘MADAMIMADAM’.”
        ”It would be better,” I continued, “to name the server ‘BOBBOB’, as this is an even number of characters and would not result in the irrevocable loss of all your business data.”
