Soul of a New Machine was one of the first books that got me interested in the tech industry, computers, etc. Reading it as a teen probably contributed substantially to the direction of my career up to the present day.
I would second the black bar for Kidder -- The Soul of a New Machine constitutes the literary foundation of our craft: it is our Odyssey. Speaking personally, I have spoken and written about Soul many times ([0][1][2]) -- and I know that its impact from me is far from unique.
RIP Tracy Kidder -- and thank you for giving us all permission to feel passion for the machine.
RIP Mr. Kidder.
Black bar?
