Since these have not been mentioned already: * Brian Bagnall trilogy on the history of Commodore/Amiga: http://variantpress.com * Severo Ornstein's "Computing in the Middle Ages", about how it used to be a professional programmer back in the early days. You can find his CHM oral history interview at https://www.youtube.com/watch?v=q243lfVdQ9E. * "Stan Veit's History of the Personal Computer". A candid view about how the PC industry unfolded. * "Introduction to Algorithms" by Udi Manber. IMHO one of the best books about how to approach problems with a programmer's mindset.
