Junior Ruby Developer


Many books have been written about Silicon Valley and the collection of geniuses, eccentrics, and mavericks who launched the "Digital Revolution"; Robert X. Cringely's Accidental Empires and Michael A. Hiltzik's Dealers of Lightning are just two excellent accounts of the unprecedented explosion of tech entrepreneurs and their game-changing success.

But Walter Isaacson goes them one better: The Innovators, his follow-up to the massive (in both sales and size) Steve Jobs, is probably the widest-ranging and most comprehensive narrative of them all. Don't let the scope or page-count deter you: while Isaacson builds the story from the 19th century--innovator by innovator, just as the players themselves stood atop the achievements of their predecessors--his discipline and era-based structure allows readers to dip in and out of digital history, from Charles Babbage's Difference Engine, to Alan Turing.
