Blown to Bits: Your Life, Liberty, and Happiness After the Digital ExplosionAddison-Wesley Professional #ad - We can’t escape this explosion of digital information and few of us want to–the benefits are too seductive. But the same engineering marvels are shattering centuries-old assumptions about privacy, free expression, identity, and personal control as more and more details of our lives are captured as digital data.
Can you control who sees all that personal information about you? can email be truly confidential, when nothing seems to be private? Shouldn’t the Internet be censored the way radio and TV are? Is it really a federal crime to download music? When you use Google or Yahoo! to search for something, how do they decide which sites to show you? Do you still have free speech in the digital world? Do you have a voice in shaping government or corporate policies about any of this? Blown to Bits offers provocative answers to these questions and tells intriguing real-life stories.

This is the ebook of the printed book and may not include any media, website access codes, or print supplements that may come packaged with the bound book. Every day, tv shows, billions of photographs, phone calls, X-rays, news stories, songs, and emails are being scattered around the world as sequences of zeroes and ones: bits.
. This book is a wake-up call to the human consequences of the digital explosion.
For AP® Computer Science Principles, 2nd Edition - Computer Science Principles: The Foundational Concepts of Computer ScienceKevin P. Hare #ad - As a new field, computer science can seem intimidating, but it should not be scary to learn or difficult to understand. If you have ever turned on a phone or surfed the internet then you have used a computer and should have a basic understanding of what happens when you click the mouse or touch the screen—and how fast it happens! Computer Science Principles introduces the creative side of computing.
How do computers convert information into ones and zeros and send it thousands of miles in a blink of the eye? What is an IP address? What do TCP/IP, HTML, DNS, and CSS stand for? How can a hard drive store large movies and thousands of songs? How can secrets be sent in plain sight? These questions—and more—are answered in Computer Science Principles.
Algorithms Unlocked The MIT PressThe MIT Press #ad - In algorithms unlocked, with limited mathematics, Thomas Cormen—coauthor of the leading college textbook on the subject—provides a general explanation, of how algorithms enable computers to solve problems. Readers will learn what computer algorithms are, how to describe them, and how to evaluate them.
And how do these mathematical formulations translate themselves into your GPS, your laptop, or your smart phone? This book offers an engagingly written guide to the basics of computer algorithms. For anyone who has ever wondered how computers solve problems, an engagingly written guide for nonexperts to the basics of computer algorithms.
Algorithms Unlocked The MIT Press #ad - Have you ever wondered how your gps can find the fastest way to your destination, selecting one route from seemingly countless possibilities in mere seconds? How your credit card account number is protected when you make a purchase over the Internet? The answer is algorithms. They will discover simple ways to search for information in a computer; methods for rearranging information in a computer into a prescribed order “sorting”; how to solve basic problems that can be modeled in a computer with a mathematical structure called a “graph” useful for modeling road networks, dependencies among tasks, and financial relationships; how to solve problems that ask questions about strings of characters such as DNA structures; the basic principles behind cryptography; fundamentals of data compression; and even that there are some problems that no one has figured out how to solve on a computer in a reasonable amount of time.

Once Upon an Algorithm: How Stories Explain Computing The MIT PressThe MIT Press #ad - This simple daily routine solves a recurring problem through a series of well-defined steps. In computer science, such a routine is called an algorithm. Erwig illustrates a series of concepts in computing with examples from daily life and familiar stories. How hansel and gretel, harry potter, Sherlock Holmes, the movie Groundhog Day, and other familiar stories illustrate the concepts of computing.
Picture a computer scientist, staring at a screen and clicking away frantically on a keyboard, hacking into a system, or perhaps developing an app. Getting up in the morning, take a shower, get dressed, for example: You get up, eat breakfast. In once upon an algorithm, martin Erwig explains computation as something that takes place beyond electronic computers, and computer science as the study of systematic problem solving.
Along the way, erwig also discusses representations and different ways to organize data; “intractable” problems; language, syntax, and ambiguity; control structures, loops, and the halting problem; different forms of recursion; and rules for finding errors in algorithms. This engaging book explains computation accessibly and shows its relevance to daily life.
Once Upon an Algorithm: How Stories Explain Computing The MIT Press #ad - Something to think about next time we execute the algorithm of getting up in the morning. The movie groundhog day illustrates the problem of unsolvability; Sherlock Holmes manipulates data structures when solving a crime; the magic in Harry Potter's world is understood through types and abstraction; and Indiana Jones demonstrates the complexity of searching.
Hansel and gretel, for example, execute an algorithm to get home from the forest.
In Pursuit of the Unknown: 17 Equations That Changed the WorldBasic Books #ad - The seventeen equations that form the basis for life as we know itMost people are familiar with history's great equations: Newton's Law of Gravity, for instance, or Einstein's theory of relativity. In in pursuit of the unknown, celebrated mathematician Ian Stewart untangles the roots of our most important mathematical statements to show that equations have long been a driving force behind nearly every aspect of our lives.
Using seventeen of our most crucial equations--including the wave equation that allowed engineers to measure a building's response to earthquakes, and the Black-Scholes model, saving countless lives, used by bankers to track the price of financial derivatives over time--Stewart illustrates that many of the advances we now take for granted were made possible by mathematical discoveries.
In Pursuit of the Unknown: 17 Equations That Changed the World #ad - An approachable, in pursuit of the unknown is a penetrating exploration of how we have also used equations to make sense of, and informative guide to the mathematical building blocks of modern life, and in turn influence, lively, our world. But the way these mathematical breakthroughs have contributed to human progress is seldom appreciated.
Understanding the Digital World: What You Need to Know about Computers, the Internet, Privacy, and SecurityPrinceton University Press #ad - Through computers, governments and companies increasingly monitor what we do. It explains, precisely and carefully, not only how they operate but also how they influence our daily lives, in terms anyone can understand, no matter what their experience and knowledge of technology. Criminals have all-too-easy access to our data.
Some of them are highly visible, tablets, cell phones, in laptops, and smart watches. Social networks and advertisers know far more about us than we should be comfortable with, using information we freely give them. But most are invisible, power grids, cars, transportation systems, like those in appliances, medical equipment, and weapons.
This book also touches on fundamental ideas from computer science and some of the inherent limitations of computers. It includes numerous color illustrations, notes on sources for further exploration, and a glossary to explain technical terms and buzzwords. Understanding the digital World is a must-read for all who want to know more about computers and communications.
