Programming Elixir

You want to explore functional programming, but are put off by the academic feel (tell me about monads just one more time).

Elixir’s pragmatic syntax and built-in support for metaprogramming will make you productive and keep you interested for the long haul. This book is the introduction to Elixir for experienced programmers.

Fire in the Valley

In the 1970s, while their contemporaries were protesting the computer as a tool of dehumanization and oppression, a motley collection of college dropouts, hippies, and electronics fanatics were engaged in something much more subversive. Obsessed with the idea of getting computer power into their own hands, they launched from their garages a hobbyist movement that grew into an industry, and ultimately a social and technological revolution. What they did was invent the personal computer: not just a new device, but a watershed in the relationship between man and machine. This is their story.
