But if code isn´t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn´t have to be that way. Noted software expert Robert C. Martin presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship . Martin has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code ´´on the fly´´ into a book that will instill within you the values of a software craftsman and make you a better programmer-but only if you work at it. What kind of work will you be doing? You´ll be reading code-lots of code. And you will be challenged to think about what´s right about that code, and what´s wrong with it. More importantly, you will be challenged to reassess your professional values and your commitment to your craft. Clean Code is divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study is an exercise in cleaning up code-of transforming a code base that has some problems into one that is sound and efficient. The third part is the payoff: a single chapter containing a list of heuristics and ´´smells´´ gathered while creating the case studies. The result is a knowledge base that describes the way we think when we write, read, and clean code. Readers will come away from this book understanding How to tell the difference between good and bad code How to write good code and how to transform bad code into good code How to create good names, good functions, good objects, and good classes How to format code for maximum readability How to implement complete error handling without obscuring code logic How to unit test and practice test-driven development This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.
Facebook´s algorithms shaping the news. Uber´s cars flocking the streets. Revolution on Twitter and romance on Tinder. We live in a world constructed of computer code. Coders - software programmers - are the people who built it for us. And yet their worlds and minds are little known to outsiders. In Coders , Wired columnist Clive Thompson presents a brilliantly original anthropological reckoning with the most influential tribe in today´s world, interrogating who they are, how they think, what they value, what qualifies as greatness in their world, and what should give us pause. One of the most prominent journalists writing on technology today, Clive Thompson takes us into the minds of coders, the most quietly influential people on the planet, in a journey into the heart of the machine - and the men and women who made it.
Hello, world. Facebook´s algorithms shaping the news. Self-driving cars roaming the streets. Revolution on Twitter and romance on Tinder. We live in a world constructed of code--and coders are the ones who built it for us. From acclaimed tech writer Clive Thompson comes a brilliant anthropological reckoning with the most powerful tribe in the world today, computer programmers, in a book that interrogates who they are, how they think, what qualifies as greatness in their world, and what should give us pause. They are the most quietly influential people on the planet, and Coders shines a light on their culture. In pop culture and media, the people who create the code that rules our world are regularly portrayed in hackneyed, simplified terms, as ciphers in hoodies. Thompson goes far deeper, dramatizing the psychology of the invisible architects of the culture, exploring their passions and their values, as well as their messy history. In nuanced portraits, Coders takes us close to some of the great programmers of our time, including the creators of Facebook´s News Feed, Instagram, Google´s cutting-edge AI, and more. Speaking to everyone from revered ´´10X´´ elites to neophytes, back-end engineers and front-end designers, Thompson explores the distinctive psychology of this vocation--which combines a love of logic, an obsession with efficiency, the joy of puzzle-solving, and a superhuman tolerance for mind-bending frustration. Along the way, Coders thoughtfully ponders the morality and politics of code, including its implications for civic life and the economy. Programmers shape our everyday behavior: When they make something easy to do, we do more of it. When they make it hard or impossible, we do less of it. Thompson wrestles with the major controversies of our era, from the ´´disruption´´ fetish of Silicon Valley to the struggle for inclusion by marginalized groups. In his accessible, erudite style, Thompson unpacks the surprising history of the field, beginning with the first coders -- brilliant and pioneering women, who, despite crafting some of the earliest personal computers and programming languages, were later written out of history. Coders introduces modern crypto-hackers fighting for your privacy, AI engineers building eerie new forms of machine cognition, teenage girls losing sleep at 24/7 hackathons, and unemployed Kentucky coal-miners learning a new career. At the same time, the book deftly illustrates how programming has become a marvelous new art form--a source of delight and creativity, not merely danger. To get as close to his subject as possible, Thompson picks up the thread of his own long-abandoned coding skills as he reckons, in his signature, highly personal style, with what superb programming looks like. To understand the world today, we need to understand code and its consequences. With Coders, Thompson gives a definitive look into the heart of the machine.

Change your daily routine, transform your health. Circadian rhythms are biological processes or clocks that exist in each one of our cells. Programmed to turn genes on or off at different times of the day or night, they influence every aspect of our health from weight and energy levels through to resistance to disease and infection, and how well we sleep. Now, in The Circadian Code , this new science is revealed, showing that the timings of our day (when we eat, sleep, exercise, work) are more crucial than we ever thought before. And that, most importantly, if your daily schedule is out of sync with your circadian rhythms, you can fix it! Whether you are a shift worker, a frustrated dieter, someone suffering from sleep problems or chronic illness, whatever your health concern, The Circadian Code is the key to unlocking your health.

In ancient, pre-literate cultures across the globe, tribal elders had encyclopedic memories. They could name all the animals and plants across a landscape, identify the stars in the sky and recite the history of their people. Yet today, most of us struggle to memorize more than a short poem. Using traditional Aboriginal Australian song lines as a starting point, Lynne Kelly has since identified the powerful memory technique used by our ancestors and indigenous people around the world. In turn, she has then discovered that this ancient memory technique is the secret purpose behind the great prehistoric monuments like Stonehenge, which have puzzled archaeologists for so long. The stone circles across Britain and northern Europe, the elaborate stone houses of New Mexico, huge animal shapes in Peru, the statues of Easter Island - these all serve as the most effective memory system ever invented by humans. They allowed people in non-literate cultures to memorize the vast amounts of information they needed to survive. But how? For the first time, Lynne Kelly reveals the purpose of these monuments and their uses as ´memory places´, and shows how we can use this ancient technique to train our minds.
