Software applications have taken over our lives. We use and are used by software many times a day. Nevertheless, we know very little about the invisibly ubiquitous workers who write software. Who are they and how do they perceive their own practice? How does that shape the ways in which they collaborate to build the myriad of apps that we use every day? Coderspeak provides a critical approach to the digital transformation of our world through an engaging and thoughtful analysis of the people who write software. It is a focused and in-depth look at one programming language and its community – Ruby - based on ethnographic research at a London company and conversations with members of the wider Ruby community in Europe, the Americas and Japan. This book shows that the place people write code, the language they write it in and the stories shared by that community are crucial in questioning and unpacking what it means to be a ‘coder’. Understanding this social group is essential if we are to grasp a future (and a present) in which computer programming increasingly dominates our lives. Praise for Coderspeak 'Heurich perfectly captures the generous camaraderie, quirky spirit and intellectual curiosity at the heart of the Ruby world. Packed with tidbits of Ruby history, code snippets, and fascinating conversations, this book has something to teach every Rubyist.' Jemma Issroff, Ruby Core Team
Code
The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock! Chapter 21: The Arithmetic Logic Unit Chapter 22: Registers and Busses Chapter 23: CPU Control Signals Chapter 24: Jumps, Loops, and Calls Chapter 28: The World Brain From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.

From the dots and dashes of Morse code to the 0s and 1s of computer programming, "Code" describes the ingenious ways humans have adapted language systems--code--to invent the machinery of the modern age. Petzold uses everyday household objects and readily recognizable codes such as Braille and Morse to build a context for understanding how computers work.
