The power curve
Besides being a software developer and photographer, I take a deep interest in spaceflight and love reading about the history and development of air- and spacecraft, with a special focus on early space program development.
A few books I've read in the past couple years have gone beyond being interesting just for their historic content—they gave me a lot of ideas to reflect on in relation to my approach to software development, especially what I'd term 'professional' software development (vs. hacking something together for fun, or churning out brochureware sites or cookie-cutter apps).
One book in particular, Failure is Not an Option (by Gene Kranz, director of Mission Control during NASA's early days into the Apollo era), illustrates high-performing teams operating well under pressure and with high stakes.
