I'm working to finish George Dyson's "Turing's Cathedral" but it is tough sledding. The author, rather than telling the story of the development of the computer at the Institute for Advanced Study in Princeton, diverges into the type of brick used in the computer building, the professions of the parents of the scientists who worked there, the design considerations of capacitive memory versus 'tank memory' and a thousand other minutae I couldn't care less about. This is what happens when a person who loves researching a book works without a deadline.
