Sunday Times bestselling author Sean Smith tells the extraordinary story of a modern cultural icon: Harry Styles.

"Leading technologists, historians, and journalists reveal the stories behind the computer coding that touches all aspects of life-for better or worse. Few of us give much thought to computer code or how it comes to be. The very word "code" makes it sound immutable or even inevitable. "You Are Not Expected to Understand This" demonstrates that, far from being preordained, computer code is the result of very human decisions, ones we all live with when we use social media, take photos, drive our cars, and engage in a host of other activities. Everything from law enforcement to space exploration relies on code written by people who, at the time, made choices and assumptions that would have long-lasting, profound implications for society. Torie Bosch brings together many of today's leading technology experts to provide new perspectives on the codes that shape our lives. Contributors discuss a host of topics, such as how university databases were programmed long ago to accept only two genders, what the person who programmed the very first pop-up ad was thinking at the time, the first computer worm, the Bitcoin white paper, and perhaps the most famous seven words in Unix history: "You are not expected to understand this." This compelling book tells the human stories behind programming, enabling those of us who don't think much about code to recognize its importance, and those who work with it every day to better understand the long-term effects of the decisions they make.

To be a top performer in the digital economyto become truly future readyyou need a playbook. Now you have one.It seems like almost every company you can think ofincluding your ownhas embarked on a digital transformation journey. The problem is, many companies start down the road without a good sense of where they are going or a clear idea of how they will create and capture digital value. Not surprisingly, this leads to problems: failure to realize the value from digital in their bottom lines, wasted resources and effort, added complexity and dysfunction.This compact, no-nonsense book provides a solution. In their years of working with senior executives around the world, MIT research scientists Stephanie Woerner, Peter Weill, and Ina Sebastian noticed that these leaders knew they had to transform their businesses, but lacked a coherent framework and a common languagea playbookto guide and motivate their employees and keep everyone focused on a common goal.Future Ready is that playbook. Based on years of rigorous research with data from more than a thousand companiesBBVA, CEMEX, DBS, Fidelity, Maersk, and many othersthe book provides a powerful, field-tested four pathways framework that offers insights into the important dimensions at which a firm must excel in order to be competitive, as well as the organizational disruptions that every firm must manage as part of the transformation journey.The book includes instructive examples, sharp analyses, assessments to help companies benchmark themselves against top performers, and many illuminating visuals to help crystallize the data and ideas.Woerner, Weill, and Sebastian show that the goal isn't digital transformation but rather a profound business transformation. Future Ready is your essential guide for becoming a top performer in the digital economy.

How a new breed of dictators holds power by manipulating information and faking democracyHitler, Stalin, and Mao ruled through violence, fear, and ideology. But in recent decades a new breed of media-savvy strongmen has been redesigning authoritarian rule for a more sophisticated, globally connected world. In place of overt, mass repression, rulers such as Vladimir Putin, Recep Tayyip Erdogan, and Viktor Orban control their citizens by distorting information and simulating democratic procedures. Like spin doctors in democracies, they spin the news to engineer support. Uncovering this new brand of authoritarianism, Sergei Guriev and Daniel Treisman explain the rise of such "e;spin dictators,"e; describing how they emerge and operate, the new threats they pose, and how democracies should respond.Spin Dictators traces how leaders such as Singapore's Lee Kuan Yew and Peru's Alberto Fujimori pioneered less violent, more covert, and more effective methods of monopolizing power. They cultivated an image of competence, concealed censorship, and used democratic institutions to undermine democracy, all while increasing international engagement for financial and reputational benefits. The book reveals why most of today's authoritarians are spin dictators-and how they differ from the remaining "e;fear dictators"e; such as Kim Jong-un and Bashar al-Assad, as well as from masters of high-tech repression like Xi Jinping.Offering incisive portraits of today's authoritarian leaders, Spin Dictators explains some of the great political puzzles of our time-from how dictators can survive in an age of growing modernity to the disturbing convergence and mutual sympathy between dictators and populists like Donald Trump.

Brought to you by Penguin. How can we be confident about making plans? How might we feel secure despite the future being unknown? How do we learn to feel at peace with the unexpected?When we think about the future it can be difficult to feel that we have any control. We aren't confident that we can take actions and make decisions that help determine what happens next. We want to feel prepared, hopeful and equipped, and to face the future with optimism. Or, better yet, change the future. But how do we map out our lives when it feels impossible to predict what the world will be like next week, let alone next year?Jane McGonigal, a renowned future forecaster, reveals that 'unimaginable' events aren't unimaginable before they happen. It is possible to see them coming and it's a mindset that can be learned by engaging with tools, games and ideas that will allow you to dive into the future before you live it. By learning to think the unthinkable and imagine the unimaginable you can better plan for a future you'd like to see. And by seeing what's coming faster, you can adapt to new challenges, reduce anxiety, and build hope and resilience.

An accessible yet rigorous crash course on recursive programming using Python and JavaScript examples.Recursion has an intimidating reputation: it's considered to be an advanced computer science topic frequently brought up in coding interviews. But there's nothing magical about recursion. The Recursive Book of Recursion uses Python and JavaScript examples to teach the basics of recursion, exposing the ways that it's often poorly taught and clarifying the fundamental principles of all recursive algorithms. You'll learn when to use recursive functions (and, most importantly, when not to use them), how to implement the classic recursive algorithms often brought up in job interviews, and how recursive techniques can help solve countless problems involving tree traversal, combinatorics, and other tricky topics. This project-based guide contains complete, runnable programs to help you learn: How recursive functions make use of the call stack, a critical data structure almost never discussed in lessons on recursionHow the head-tail and "leap of faith" techniques can simplify writing recursive functionsHow to use recursion to write custom search scripts for your filesystem, draw fractal art, create mazes, and moreHow optimization and memoization make recursive algorithms more efficient Al Sweigart has built a career explaining programming concepts in a fun, approachable manner. If you've shied away from learning recursion but want to add this technique to your programming toolkit, or if you're racing to prepare for your next job interview, this book is for you.
