Here's what programmers today are saying: "I love Awk." "Awk is amazing." "It is just so damn good." "Awk is just right." "Awk is awesome." "Awk has always been a language that I loved."

It's easy: "Simple, fast and lightweight." "Absolutely efficient to learn because there isn't much to learn." "3-4 hours to learn the language from start to finish." "I can teach it to new engineers in less than 2 hours."

It's productive: "Whenever I need to do a complex analysis of a semi-structured text file in less than a minute, Awk is my tool." "Learning Awk was the best bang for buck investment of time in my entire career." "Designed to chew through lines of text files with ease, with great defaults that minimize the amount of code you actually have to write to do anything."

It's always available: "AWK runs everywhere." "A reliable Swiss Army knife that is always there when you need it." "Many systems lack Perl or Python, but include Awk."

An engrossing origin story for the personal computer—showing how the Apple II’s software helped a machine transcend from hobbyists’ plaything to essential home appliance.  Skip the iPhone, the iPod, and the Macintosh. If you want to understand how Apple Inc. became an industry behemoth, look no further than the 1977 Apple II. Designed by the brilliant engineer Steve Wozniak and hustled into the marketplace by his Apple cofounder Steve Jobs, the Apple II became one of the most prominent personal computers of this dawning industry.  The Apple II was a versatile piece of hardware, but its most compelling story isn’t found in the feat of its engineering, the personalities of Apple’s founders, or the way it set the stage for the company’s multibillion-dollar future. Instead, historian Laine Nooney shows, what made the Apple II iconic was its software. In software, we discover the material reasons people bought computers. Not to hack, but to play. Not to code, but to calculate. Not to program, but to print. The story of personal computing in the United States is not about the evolution of hackers—it’s about the rise of everyday users.  Recounting a constellation of software creation stories, Nooney offers a new understanding of how the hobbyists’ microcomputers of the 1970s became the personal computer we know today. From iconic software products like VisiCalc and The Print Shop to historic games like Mystery House and Snooper Troops to long-forgotten disk-cracking utilities, The Apple II Age offers an unprecedented look at the people, the industry, and the money that built the microcomputing milieu—and why so much of it converged around the pioneering Apple II.
