More importantly, this book provides a framework for thinking about computer organization and design that will enable the reader to continue the lifetime of learning necessary for staying at the forefront of this competitive discipline. --John Crawford Intel Fellow Director of Microprocessor Architecture, Intel The performance of software systems is dramatically affected by how well software designers understand the basic hardware technologies at work in a system. Similarly, hardware designers must understand the far reaching effects their design decisions have on software applications. For readers in either category, this classic introduction to the field provides a deep look into the computer. It demonstrates the relationship between the software and hardware and focuses on the foundational concepts that are the basis for current computer design. Using a distinctive learning by evolution approach the authors present each idea from its first principles, guiding readers through a series of worked examples that incrementally add more complex instructions until they ha

    The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

    In 1997, she wroteClose to the Machine, the now classic and still definitive account of life as a coder at the birth of what would be a sweeping technological, cultural, and financial revolution.The intervening twenty years has seen, among other things, the rise of the Internet, the ubiquity of once unimaginably powerful computers, and the thorough transformation of our economy and society—as Ullman’s clique of socially awkward West Coast geeks became our new elite, elevated for and insulated by a technical mastery that few could achieve.In Life in Code, Ullman presents a series of essays that unlock and explain—and don’t necessarily celebrate—how we got to now, as only she can, with a fluency and expertise that’s unusual in someone with her humanistic worldview, and with the sharp insight and brilliant prose that are uniquely her own. Life in Code is an essential text toward our understanding of the last twenty years—and the next twenty.

    To its adherents, it is an elegant statement about learning from experience. To its opponents, it is subjectivity run amok.In the first-ever account of Bayes' rule for general readers, Sharon Bertsch McGrayne explores this controversial theorem and the human obsessions surrounding it. She traces its discovery by an amateur mathematician in the 1740s through its development into roughly its modern form by French scientist Pierre Simon Laplace. She reveals why respected statisticians rendered it professionally taboo for 150 years—at the same time that practitioners relied on it to solve crises involving great uncertainty and scanty information (Alan Turing's role in breaking Germany's Enigma code during World War II), and explains how the advent of off-the-shelf computer technology in the 1980s proved to be a game-changer. Today, Bayes' rule is used everywhere from DNA de-coding to Homeland Security.Drawing on primary source material and interviews with statisticians and other scientists, The Theory That Would Not Die is the riveting account of how a seemingly simple theorem ignited one of the greatest controversies of all time.

    As suddenly as they gained popularity, they were made obsolete by the next big thing - a newfangled system called the Internet. Commodork: Sordid Tales from a BBS Junkie takes its readers on an exciting journey through the BBS era. Through the author's personal tales and adventures, readers will discover more about these amazing times and what it was like to grow up online. With tales of copyfests, BBS parties and random acts of online debauchery, those who were there will find themselves reminiscing, while those who weren't will enjoy learning about life ""before the 'net."" You know, back when we used to modem uphill, both ways in the snow.

    Increasingly, the decisions that affect our lives--where we go to school, whether we can get a job or a loan, how much we pay for health insurance--are being made not by humans, but by machines. In theory, this should lead to greater fairness: Everyone is judged according to the same rules.But as mathematician and data scientist Cathy O'Neil reveals, the mathematical models being used today are unregulated and uncontestable, even when they're wrong. Most troubling, they reinforce discrimination--propping up the lucky, punishing the downtrodden, and undermining our democracy in the process.

    The exam is designed to ensure that someone who is handling computer security in a company has a standardized body of knowledge. The book is composed of 10 domains of the Common Body of Knowledge. In each section, it defines each domain. It also provides tips on how to prepare for the exam and take the exam. It also contains CISSP practice quizzes to test ones knowledge. The first domain provides information about risk analysis and mitigation. It also discusses security governance. The second domain discusses different techniques for access control, which is the basis for all the security disciplines. The third domain explains the concepts behind cryptography, which is a secure way of communicating that is understood only by certain recipients. Domain 5 discusses security system design, which is fundamental for operating the system and software security components. Domain 6 is a critical domain in the Common Body of Knowledge, the Business Continuity Planning, and Disaster Recovery Planning. It is the final control against extreme events such as injury, loss of life, or failure of an organization. Domains 7, 8, and 9 discuss telecommunications and network security, application development security, and the operations domain, respectively. Domain 10 focuses on the major legal systems that provide a framework in determining the laws about information system.

    The book is short - around an hour of reading - and details everything from when I first decided naturism appealed to me, to my thoughts after the holiday.

    We never think it’s going to happen to us. We never think it will happen today. But it does, and it happened to Christy. In an effort to find solace, Christy tried Googling, “What do I do when my baby dies?” Unfortunately, there just aren’t many good resources out there—at least not any that are truly honest, not sugar-coated with clichés. “Almost a Mother: Love, Loss, and Finding Your People When Your Baby Dies” is Christy’s way of reaching out to those who have experienced a horrible loss of any kind, of any magnitude, in the hopes of building a community of support and love. And, in her words, “I just wanted to know that I wasn’t crazy because I wanted to punch the pregnant lady at Target in the face.”

    His guitarist is trying to get them all killed. Fans are stealing his things. Mechanics are rebuking his lifestyle. Even his own fragile, uptight psyche is antagonizing him.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.

    Digital technologies—with hardware, software, and networks at their core—will in the near future diagnose diseases more accurately than doctors can, apply enormous data sets to transform retailing, and accomplish many tasks once considered uniquely human.In The Second Machine Age MIT’s Erik Brynjolfsson and Andrew McAfee—two thinkers at the forefront of their field—reveal the forces driving the reinvention of our lives and our economy. As the full impact of digital technologies is felt, we will realize immense bounty in the form of dazzling personal technology, advanced infrastructure, and near-boundless access to the cultural items that enrich our lives.Amid this bounty will also be wrenching change. Professions of all kinds—from lawyers to truck drivers—will be forever upended. Companies will be forced to transform or die. Recent economic indicators reflect this shift: fewer people are working, and wages are falling even as productivity and profits soar.Drawing on years of research and up-to-the-minute trends, Brynjolfsson and McAfee identify the best strategies for survival and offer a new path to prosperity. These include revamping education so that it prepares people for the next economy instead of the last one, designing new collaborations that pair brute processing power with human ingenuity, and embracing policies that make sense in a radically transformed landscape.A fundamentally optimistic book, The Second Machine Age alters how we think about issues of technological, societal, and economic progress.
