    Through the worst years of the Great Depression as many as five thousand laborers toiled twenty-four hours a day, seven days a week, to erect the huge structure that would harness the Colorado River and transform the American West.Construction of the giant dam was a triumph of human ingenuity, yet the full story of this monumental endeavor has never been told. Now, in an engrossing, fast-paced narrative, Joseph E. Stevens recounts the gripping saga of Hoover Dam. Drawing on a wealth of material, including manuscript collections, government documents, contemporary newspaper and magazine accounts, and personal interviews and correspondence with men and women who were involved with the construction, he brings the Hoover Dam adventure to life.Described here in dramatic detail are the deadly hazards the work crews faced as they hacked and blasted the dam’s foundation out of solid rock; the bitter political battles and violent labor unrest that threatened to shut the job down; the deprivation and grinding hardship endured by the workers’ families; the dam builders’ gambling, drinking, and whoring sprees in nearby Las Vegas; and the stirring triumphs and searing moments of terror as the massive concrete wedge rose inexorably from the canyon floor.Here, too, is an unforgettable cast of characters: Henry Kaiser, Warren Bechtel, and Harry Morrison, the ambitious, headstrong construction executives who gambled fortune and fame on the Hoover Dam contract; Frank Crowe, the brilliant, obsessed field engineer who relentlessly drove the work force to finish the dam two and a half years ahead of schedule; Sims Ely, the irascible, teetotaling eccentric who ruled Boulder City, the straightlaced company town created for the dam workers by the federal government; and many more men and women whose courage and sacrifice, greed and frailty, made the dam’s construction a great human, as well as technological, adventure.Hoover Dam is a compelling, irresistible account of an extraordinary American epic.

    Millions fill 100,000-seat stadiums every Saturday; tens of millions more watch on television every weekend. The 2013 Discover BCS National Championship game between Notre Dame and Alabama had a viewership of 26.4 million people, second only to the Super Bowl. Billions of dollars from television deals now flow into the game; the average budget for a top-ten team is $80 million; top coaches make more than $3 million a year; the highest paid, more than $5 million.     But behind this glittering success are darker truths: “athlete-students” working essentially full-time jobs with no share in the oceans of money; players who often don’t graduate and end their careers with broken bodies; “janitors” who clean up player misconduct; football “hostesses” willing to do whatever it takes to land a top recruit; seven-figure black box recruiting slush funds. And this: Despite the millions of dollars pouring into the game, 90 percent of major athletic departments still lose money. Yet schools remain caught up in an ever-escalating “arms race”—at the expense of academic scholarships, facilities and faculty.     Celebrated investigative journalists Jeff Benedict and Armen Keteyian were granted unprecedented access during the 2012 season to programs at the highest levels across the country at a time of convulsive change in college football. Through dogged reporting, they explored every nook and cranny of this high-powered machine, and reveal how it operates from the inside out. The result: the system through the eyes of athletic directors and coaches, high-flying boosters and high-profile TV stars, five-star recruits and tireless NCAA investigators and the kids on whom the whole vast enterprise depends.     Both a celebration of the power and pageantry of NCAA football and a groundbreaking, thought-provoking critique of its excesses, The System is the definitive book on the college game.

    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

    The solution is to rein in the market, right? Radical Markets turns this thinking--and pretty much all conventional thinking about markets, both for and against--on its head. The book reveals bold new ways to organize markets for the good of everyone. It shows how the emancipatory force of genuinely open, free, and competitive markets can reawaken the dormant nineteenth-century spirit of liberal reform and lead to greater equality, prosperity, and cooperation.Eric Posner and Glen Weyl demonstrate why private property is inherently monopolistic, and how we would all be better off if private ownership were converted into a public auction for public benefit. They show how the principle of one person, one vote inhibits democracy, suggesting instead an ingenious way for voters to effectively influence the issues that matter most to them. They argue that every citizen of a host country should benefit from immigration--not just migrants and their capitalist employers. They propose leveraging antitrust laws to liberate markets from the grip of institutional investors and creating a data labor movement to force digital monopolies to compensate people for their electronic data.Only by radically expanding the scope of markets can we reduce inequality, restore robust economic growth, and resolve political conflicts. But to do that, we must replace our most sacred institutions with truly free and open competition--Radical Markets shows how.

    With humor and chutzpah, attorney, commentator, and popular radio host Michael Smerconish takes on today's oversensitive culture with a collection of entertaining, outlandish anecdotes about PC gone wild-stories that are hilarious, horrifying, and unbelievably true.Why are sports leagues handing out trophies to losers? Why are little old grandmas hired to guard 200-pound prisoners? Why are newborn babies and old men with walkers singled out at the airport while likely terrorists are ushered through security with ease?This book shows through these absurdities that today's atmosphere of censorship and multiculturalism is paving the way for serious threats to our cultural identity and national security: "It's one thing for the forces of political correctness to muzzle our day-to-day lives here at home in the US, quite another when that same cancer metastasizes into the war on terror."We must eradicate the PC disease. Our sanity-and our very lives-depend on it."Michael Smerconish talks the talk: If you say unpopular things, watch out! Using vivid examples of PC rubbish, "Muzzled" will lead you into a world that would terrify Rod Serling. An entertaining and provocative book." -Bill O'Reilly"Reads like fiction, too bad it's true." -Nelson DeMille, novelist, author of "Night Fall and The General's Daughter""The PC virus is out of control . . . and it's worse than you think! In this entertaining and important book, Michael Smerconish chronicles just how mindless things have gotten in politically correct America. He tells fascinating stories that will make you laugh . . . right up until the time they make you scream. Thanks to the PC crowd, we are all living in The United States of the Absurd." -Bernard Goldberg, journalist and author of "100 People Who Are Screwing Up America," "Arrogance," and "Bias""I really squirm whenever I find myself agreeing with Smerconish. (I know the feeling is mutual.) I did a lot of squirming while reading this provocative book. All true liberals and conservatives must agree with Smerconish that the PC muzzles must be removed so that people can decide based on the marketplace of ideas." -Alan Dershowitz, Felix Frankfurter Professor of Law, Harvard and author of "Preemption""I don't often find myself on the same side of the political barricades as Michael Smerconish. But "Muzzled" is a witty, provocative, and timely book. Even when Michael is wrong, which is often, he draws you in and keeps you reading." -Arianna Huffington, author of "Pigs at the Trough" and "Fanatics and Fools""In Muzzled, my American Blood Brother of status-quo-obliterating defiance, Michael Smerconish, once again smokes out the cockroaches of political correctness . . . "Muzzled" is a great title for a book that I am convinced every American school kid should read and be tested on. If a new generation doesn't grow some intellectual balls, our Once Great Nation will continue to repeat horrific mistakes and pay the price . . . Read it. Live it." -Ted Nugent, rock star, author, television personality, and hunter extraordinaire
