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.

Naomi Klein, author of era-defining bestsellers, The Shock Doctrine, This Changes Everything and No Logo, is back with her most compulsive and personal book yet: a revelatory journey into the mirror world of our polarised age

When Naomi Klein discovered that a woman who shared her first name, but had radically different, harmful views, was getting chronically mistaken for her, it seemed too ridiculous to take seriously. Then suddenly it wasn't. She started to find herself grappling with a distorted sense of reality, becoming obsessed with reading the threats on social media, the endlessly scrolling insults from the followers of her doppelganger. Why had her shadowy other gone down such an extreme path? Why was identity - all we have to meet the world - so unstable?

To find out, Klein decided to follow her double into a bizarre, uncanny mirror world: one of conspiracy theories, anti-vaxxers and demagogue hucksters, where soft-focus wellness influencers make common cause with fire-breathing far right propagandists (all in the name of protecting 'the children'). In doing so, she lifts the lid on our own culture during this surreal moment in history, as we turn ourselves into polished virtual brands, publicly shame our enemies, watch as deep fakes proliferate and whole nations flip from democracy to something far more sinister.

This is a book for our age and for all of us; a deadly serious dark comedy which invites us to view our reflections in the looking glass. It's for anyone who has lost hours down an internet rabbit hole, who wonders why our politics has become so fatally warped, and who wants a way out of our collective vertigo and back to fighting for what really matters.

The gripping, behind-the scenes story of one of the most sophisticated surveillance weapons ever created, which is threatening democracy and human rights.

Pegasus is widely regarded as the most powerful cyber-surveillance system on the market – available to any government that can afford its multimillion-dollar price tag. The system’s creator, the NSO group, a private corporation headquartered in Israel, boasts about its ability to thwart terrorists and criminals: ‘Thousands of people in Europe owe their lives to hundreds of our company employees’, they declared in 2019. That may be true – but the Pegasus system doesn’t just catch bad guys.

Pegasus has been used by repressive regimes to spy on thousands of innocent people around the world: heads of state, diplomats, human rights defenders, lawyers, political opponents, and journalists. Virtually undetectable, the system can track a person’s daily movement in real time, gain control of the device’s microphones and cameras at will, and capture all videos, photos, emails, texts, and passwords – encrypted or not. Its full reach is not even known.

This is the gripping story of how Pegasus was uncovered, written by Laurent Richard and Sandrine Rigaud, the two intrepid reporters who revealed the scandal in collaboration with an international consortium of journalists. They received a leaked list of 50,000 mobile phone numbers, but they needed to prove NSO’s involvement. After a dangerous and secretive investigation spanning the globe, their findings shook the world. Tense and compelling, Pegasus reveals how thousands of lives have been turned upside down by this unprecedented threat, and exposes the chilling new ways governments and corporations are laying waste to human rights – and silencing innocent citizens.

The Business Analysts completely dissolves the perception that the IT industry dictates to businesses what IT systems they will use and dispels the myth that business users and IT technicians are from different planets. It suggests how to create an environment in which everybody works together in an exciting and refreshing way – a paradigm shift in the way business analysis projects are done.

The IT industry has to move to a point where it realises that the users of IT systems and the technical personnel are both equally responsible for getting the system to work. The users of the IT system should be an integral part of the team when the system is being put together. This, unfortunately, is not the norm within the industry. It is the business analyst’s responsibility, among others, to make sure that communication flows freely between all the parties involved.

This book gives the business analyst the tools and techniques to find out what the business users of IT systems really need and to guide the project to meet those needs.

From the boardrooms to the court rooms, this is the gripping story of how Apple became the world's most valuable company, and of the lawmakers and entrepreneurs determined to knock it off its pedestal.

Since the invention of the iPhone and App Store, Apple has built a near unassailable market power, controlling not only commerce, but also culture, and - increasingly - the flow of ideas.

In response, a loose rebel alliance of tech entrepreneurs has formed to lay siege to Apple, bringing together Epic Games' Tim Sweeney, Spotify's Daniel Ek, X's Elon Musk and WeChat's Pony Ma. In the trenches of popular opinion and now in the courtrooms of Europe and the United States, this rebellion aims to tear down Apple's walls and dismantle its alleged monopoly.

iWar weaves together the story of Apple's rise and reign with the political and international forces arrayed against it in the fight over control of the global digital economy. The stakes couldn't be higher.
