What makes an operating system modern? According to author Andrew Tanenbaum, it is the awareness of high-demand computer applications--primarily in the areas of multimedia, parallel and distributed computing, and security. The development of faster and more advanced hardware has driven progress in software, including enhancements to the operating system. It is one thing to run an old operating system on current hardware, and another to effectively leverage current hardware to best serve modern software applications. If you don't believe it, install Windows 3.0 on a modern PC and try surfing the Internet or burning a CD. Readers familiar with Tanenbaum's previous text, Operating Systems, know the author is a great proponent of simple design and hands-on experimentation. His earlier book came bundled with the source code for an operating system called Minux, a simple variant of Unix and the platform used by Linus Torvalds to develop Linux. Although this book does not come with any source code, he illustrates many of his points with code fragments (C, usually with Unix system calls). The first half of Modern Operating Systems focuses on traditional operating systems concepts: processes, deadlocks, memory management, I/O, and file systems. There is nothing groundbreaking in these early chapters, but all topics are well covered, each including sections on current research and a set of student problems. It is enlightening to read Tanenbaum's explanations of the design decisions made by past operating systems gurus, including his view that additional research on the problem of deadlocks is impractical except for "keeping otherwise unemployed graph theorists off the streets." It is the second half of the book that differentiates itself from older operating systems texts. Here, each chapter describes an element of what constitutes a modern operating system--awareness of multimedia applications, multiple processors, computer networks, and a high level of security. The chapter on multimedia functionality focuses on such features as handling massive files and providing video-on-demand. Included in the discussion on multiprocessor platforms are clustered computers and distributed computing. Finally, the importance of security is discussed--a lively enumeration of the scores of ways operating systems can be vulnerable to attack, from password security to computer viruses and Internet worms. Included at the end of the book are case studies of two popular operating systems: Unix/Linux and Windows 2000. There is a bias toward the Unix/Linux approach, not surprising given the author's experience and academic bent, but this bias does not detract from Tanenbaum's analysis. Both operating systems are dissected, describing how each implements processes, file systems, memory management, and other operating system fundamentals. Tanenbaum's mantra is simple, accessible operating system design. Given that modern operating systems have extensive features, he is forced to reconcile physical size with simplicity. Toward this end, he makes frequent references to the Frederick Brooks classic The Mythical Man-Month for wisdom on managing large, complex software development projects. He finds both Windows 2000 and Unix/Linux guilty of being too complicated--with a particular skewering of Windows 2000 and its "mammoth Win32 API." A primary culprit is the attempt to make operating systems more "user-friendly," which Tanenbaum views as an excuse for bloated code. The solution is to have smart people, the smallest possible team, and well-defined interactions between various operating systems components. Future operating system design will benefit if the advice in this book is taken to heart. --Pete Ostenson

    But things didn't turn out that way. For a start, we turned out to have far fewer genes than originally thought - just over 20,000, the same sort of number as a fruit fly or worm. What's more, the proportionof DNA consisting of genes coding for proteins was a mere 2%. So, was the rest of the genome accumulated 'junk'?Things have changed since those early heady days of the Human Genome Project. But the emerging picture is if anything far more exciting. In this book, John Parrington explains the key features that are coming to light - some, such as the results of the international ENCODE programme, still much debated and controversial in their scope. He gives an outline of the deeper genome, involving layers of regulatory elements controlling and coordinating the switching on and off of genes; the impact ofits 3D geometry; the discovery of a variety of new RNAs playing critical roles; the epigenetic changes influenced by the environment and life experiences that can make identical twins different and be passed on to the next generation; and the clues coming out of comparisons with the genomes ofNeanderthals as well as that of chimps about the development our species. We are learning more about ourselves, and about the genetic aspects of many diseases. But in its complexity, flexibility, and ability to respond to environmental cues, the human genome is proving to be far more subtle than we ever imagined.

    At just two years old, Nic experienced a searing pain that signaled the awakening of a new and deadly disease, one that would hurl Nic and his family up against the limits of modern medicine. For years, through false starts and failed cures, Nic holds on to life, buoyed up by his mother’s fierce drive to get him the care he needs. But when even the world’s experts are stumped by Nic’s illness, his doctors come up with a radical, long-shot plan: a step into the unknown. The next major scientific frontier, following the completion of the Human Genome Project, was to figure out how to use our new knowledge to save lives—to bring genomic or personalized medicine into reality. It’s a quest that is undertaken by researchers around the world. But it is only when geneticist Howard Jacob hears about young Nic that the finish line finally comes into sight: It’s no longer a race to make history. It’s a race to save this boy’s life. One in a Billion is an unforgettable tale of the lives that converged to launch a medical revolution. As pioneering geneticist Mary-Claire King pronounced upon learning Nic’s story: “It was as if one had heard about Case Zero of AIDS and the cure, all at once.”

    Yet despite a century of medical progress, viral and bacterial disasters continue to take us by surprise, inciting panic and dominating news cycles. From the Spanish flu to the 1924 outbreak of pneumonic plague in Los Angeles to the 1930 “parrot fever” pandemic, through the more recent SARS, Ebola, and Zika epidemics, the last one hundred years have been marked by a succession of unanticipated pandemic alarms.In The Pandemic Century, a lively account of scares both infamous and less known, Mark Honigsbaum combines reportage with the history of science and medical sociology to artfully reconstruct epidemiological mysteries and the ecology of infectious diseases. We meet dedicated disease detectives, obstructive or incompetent public health officials, and brilliant scientists often blinded by their own knowledge of bacteria and viruses. We also see how fear of disease often exacerbates racial, religious, and ethnic tensions—even though, as the epidemiologists Malik Peiris and Yi Guan write, “‘nature’ remains the greatest bioterrorist threat of all.”Like man-eating sharks, predatory pathogens are always present in nature, waiting to strike; when one is seemingly vanquished, others appear in its place. These pandemics remind us of the limits of scientific knowledge, as well as the role that human behavior and technologies play in the emergence and spread of microbial diseases.

    An epic, first-of-its-kind book, entwining leading-edge scientific discovery with the intimate stories of four individual lives, by the Pulitzer Prize–winning New York Times journalist.A terminal cancer patient rises from the grave. A medical marvel defies HIV. Two women with autoimmunity discover their own bodies have turned against them. Matt Richtel's An Elegant Defense uniquely entwines these intimate stories with science’s centuries-long quest to unlock the mysteries of sickness and health, and illuminates the immune system as never before.The immune system is our body’s essential defense network, a guardian vigilantly fighting illness, healing wounds, maintaining order and balance, and keeping us alive. Its legion of microscopic foot soldiers—from T cells to “natural killers”—patrols our body, linked by a nearly instantaneous communications grid. It has been honed by evolution over millennia to face an almost infinite array of threats.For all its astonishing complexity, however, the immune system can be easily compromised by fatigue, stress, toxins, advanced age, and poor nutrition—hallmarks of modern life—and even by excessive hygiene. Paradoxically, it is a fragile wonder weapon that can turn on our own bodies with startling results, leading today to epidemic levels of autoimmune disorders.Richtel effortlessly guides readers on a scientific detective tale winding from the Black Plague to twentieth-century breakthroughs in vaccination and antibiotics, to the cutting-edge laboratories that are revolutionizing immunology—perhaps the most extraordinary and consequential medical story of our time. The foundation that Richtel builds makes accessible revelations about cancer immunotherapy, the microbiome, and autoimmune treatments that are changing millions of lives. An Elegant Defense also captures in vivid detail how these powerful therapies, along with our behavior and environment, interact with the immune system, often for the good but always on a razor’s edge that can throw this remarkable system out of balance.Drawing on his groundbreaking reporting for the New York Times and based on extensive new interviews with dozens of world-renowned scientists, Matt Richtel has produced a landmark book, equally an investigation into the deepest riddles of survival and a profoundly human tale that is movingly brought to life through the eyes of his four main characters, each of whom illuminates an essential facet of our “elegant defense.”

    But if we are supposedly evolution’s greatest creation, why do we have such bad knees? Why do we catch head colds so often—two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there’s been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them.   A rollicking, deeply informative tour of humans’ four billion year long evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.
