    It’s about the greatest pirate in history, the most powerful executive in the music business, a revolutionary invention and an illegal website four times the size of the iTunes Music Store. Journalist Stephen Witt traces the secret history of digital music piracy, from the German audio engineers who invented the mp3, to a North Carolina compact-disc manufacturing plant where factory worker Dell Glover leaked nearly two thousand albums over the course of a decade, to the high-rises of midtown Manhattan where music executive Doug Morris cornered the global market on rap, and, finally, into the darkest recesses of the Internet.Through these interwoven narratives, Witt has written a thrilling book that depicts the moment in history when ordinary life became forever entwined with the world online — when, suddenly, all the music ever recorded was available for free. In the page-turning tradition of writers like Michael Lewis and Lawrence Wright, Witt’s deeply-reported first book introduces the unforgettable characters—inventors, executives, factory workers, and smugglers—who revolutionized an entire artform, and reveals for the first time the secret underworld of media pirates that transformed our digital lives.An irresistible never-before-told story of greed, cunning, genius, and deceit, How Music Got Free isn’t just a story of the music industry—it’s a must-read history of the Internet itself.

     Once one of Silicon Valley’s greatest success stories, Facebook has been under constant fire for the past five years, roiled by controversies and crises. It turns out that while the tech giant was connecting the world, they were also mishandling users’ data, spreading fake news, and amplifying dangerous, polarizing hate speech. The company, many said, had simply lost its way. But the truth is far more complex. Leadership decisions enabled, and then attempted to deflect attention from, the crises. Time after time, Facebook’s engineers were instructed to create tools that encouraged people to spend as much time on the platform as possible, even as those same tools boosted inflammatory rhetoric, conspiracy theories, and partisan filter bubbles. And while consumers and lawmakers focused their outrage on privacy breaches and misinformation, Facebook solidified its role as the world’s most voracious data-mining machine, posting record profits, and shoring up its dominance via aggressive lobbying efforts. Drawing on their unrivaled sources, Sheera Frenkel and Cecilia Kang take readers inside the complex court politics, alliances and rivalries within the company to shine a light on the fatal cracks in the architecture of the tech behemoth. Their explosive, exclusive reporting led them to a shocking conclusion: The missteps of the last five years were not an anomaly but an inevitability—this is how Facebook was built to perform. In a period of great upheaval, growth has remained the one constant under the leadership of Mark Zuckerberg and Sheryl Sandberg. Both have been held up as archetypes of uniquely 21st century executives—he the tech “boy genius” turned billionaire, she the ultimate woman in business, an inspiration to millions through her books and speeches. But sealed off in tight circles of advisers and hobbled by their own ambition and hubris, each has stood by as their technology is coopted by hate-mongers, criminals and corrupt political regimes across the globe, with devastating consequences. In An Ugly Truth, they are at last held accountable.

    The tycoon had close ties to the U.S. government, and he soon asked Elizebeth to apply her language skills to an exciting new venture: code-breaking. There she met the man who would become her husband, groundbreaking cryptologist William Friedman. In The Woman Who Smashed Codes, Jason Fagone chronicles the life of Elizebeth Smith who played an integral role in our nation's history for forty years. After World War I, Smith used her talents to catch gangsters and smugglers during Prohibition, then accepted a covert mission to discover and expose Nazi spy rings that were spreading like wildfire across South America, advancing ever closer to the United States. As World War II raged, Elizebeth fought a highly classified battle of wits against Hitler's Reich, cracking multiple versions of the Enigma machine used by German spies. Meanwhile, inside an Army vault in Washington, William worked furiously to break Purple, the Japanese version of Enigma--and eventually succeeded, at a terrible cost to his personal life.Fagone unveils America's code-breaking history through the prism of Smith's life, bringing into focus the unforgettable events and colorful personalities that would help shape modern intelligence.

    These are today's sins of science—as deplorable as mistaken past ideas about advocating racial purity or using lobotomies as a cure for mental illness. These unwitting errors add up to seven lessons both cautionary and profound, narrated by renowned author and speaker Paul A. Offit. Offit uses these lessons to investigate how we can separate good science from bad, using some of today's most controversial creations—e-cigarettes, GMOs, drug treatments for ADHD—as case studies. For every "Aha!" moment that should have been an "Oh no," this book is an engrossing account of how science has been misused disastrously—and how we can learn to use its power for good.

    But the president insisted there was nothing to worry about.Fortunately, we are still a nation of skeptics. Fortunately, there are those among us who study pandemics and are willing to look unflinchingly at worst-case scenarios. Michael Lewis’s taut and brilliant nonfiction thriller pits a band of medical visionaries against the wall of ignorance that was the official response of the Trump administration to the outbreak of COVID-19.The characters you will meet in these pages are as fascinating as they are unexpected. A thirteen-year-old girl’s science project on transmission of an airborne pathogen develops into a very grown-up model of disease control. A local public-health officer uses her worm’s-eye view to see what the CDC misses, and reveals great truths about American society. A secret team of dissenting doctors, nicknamed the Wolverines, has everything necessary to fight the pandemic: brilliant backgrounds, world-class labs, prior experience with the pandemic scares of bird flu and swine flu…everything, that is, except official permission to implement their work.Michael Lewis is not shy about calling these people heroes for their refusal to follow directives that they know to be based on misinformation and bad science. Even the internet, as crucial as it is to their exchange of ideas, poses a risk to them. They never know for sure who else might be listening in.

    He relies on phrases like, “fake news,” “build the wall,” and continues to spread the divisive mentality of us-vs.-them. He lies constantly, has no conscience, never admits when he is wrong, and projects all of his shortcomings on to others. He has become more authoritarian, more outrageous, and yet many of his followers remain blindly devoted. Scott Adams, the creator of Dilbert and a major Trump supporter, calls him one of the most persuasive people living. His need to squash alternate information and his insistence of constant ego stroking are all characteristics of other famous leaders—cult leaders. In The Cult of Trump, mind-control and licensed mental health expert Steven Hassan draws parallels between our current president and people like Jim Jones, David Koresh, Ron Hubbard and Sun Myung Moon, arguing that this presidency is in many ways like a destructive cult. He specifically details the ways in which people are influenced through an array of social psychology methods and how they become fiercely loyal and obedient. Hassan was a former “Moonie” himself, and he draws on his forty years of personal and professional experience studying hypnosis and destructive cults, working as a deprogrammer, and a strategic communications interventionist. He emphasizes why it’s crucial that we recognize ways to identify and protect ourselves and our loved ones. The Cult of Trump is an accessible and in-depth analysis of the president, showing that under the right circumstances, even sane, rational, well-adjusted people can be persuaded to believe the most outrageous ideas. Hassan’s book is essential reading for anyone wanting to understand the Trump phenomenon and looking for a way forward.

    Tens of millions of people over several states are affected. For those without access to a generator, there is no running water, no sewage, no refrigeration or light. Food and medical supplies are dwindling. Devices we rely on have gone dark. Banks no longer function, looting is widespread, and law and order are being tested as never before.  It isn’t just a scenario. A well-designed attack on just one of the nation’s three electric power grids could cripple much of our infrastructure—and in the age of cyberwarfare, a laptop has become the only necessary weapon. Several nations hostile to the United States could launch such an assault at any time. In fact, as a former chief scientist of the NSA reveals, China and Russia have already penetrated the grid. And a cybersecurity advisor to President Obama believes that independent actors—from “hacktivists” to terrorists—have the capability as well. “It’s not a question of if,” says Centcom Commander General Lloyd Austin, “it’s a question of when.”  And yet, as Koppel makes clear, the federal government, while well prepared for natural disasters, has no plan for the aftermath of an attack on the power grid.  The current Secretary of Homeland Security suggests keeping a battery-powered radio.In the absence of a government plan, some individuals and communities have taken matters into their own hands. Among the nation’s estimated three million “preppers,” we meet one whose doomsday retreat includes a newly excavated three-acre lake, stocked with fish, and a Wyoming homesteader so self-sufficient that he crafted the thousands of adobe bricks in his house by hand. We also see the unrivaled disaster preparedness of the Mormon church, with its enormous storehouses, high-tech dairies, orchards, and proprietary trucking company – the fruits of a long tradition of anticipating the worst. But how, Koppel asks, will ordinary civilians survive?With urgency and authority, one of our most renowned journalists examines a threat unique to our time and evaluates potential ways to prepare for a catastrophe that is all but inevitable.

      Working in a secretive organization known as Section T, a team of physicists, engineers, and everyday Joes and Janes took on a devilish challenge. To help the Allies knock airplanes out of the air, they created one of the world’s first “smart weapons.” Against overwhelming odds and in a race against time, mustering every scrap of resource, ingenuity, and insight, the scientists of Section T would eventually save countless lives, rescue the city of London from the onslaught of a Nazi superweapon, and help bring about the Axis defeat. A holy grail sought after by Allied and Axis powers alike, their unlikely innovation ranks with the atomic bomb as one of the most revolutionary technologies of the Second World War. Until now, their tale was largely untold.   For fans of Erik Larson and Ben Macintyre, set amidst the fog of espionage, dueling spies, and the dawn of an age when science would determine the fate of the world, 12 Seconds of Silence is a tribute to the extraordinary wartime mobilization of American science and the ultimate can-do story.

    A full Rails application probably has less total code than the XML you'd need to configure the same application in other frameworks. With this book you'll learn how to use "ActiveRecord" to connect business objects and database tables. No more painful object-relational mapping. Just create your business objects and let Rails do the rest. You'll learn how to use the "Action Pack" framework to route incoming requests and render pages using easy-to-write templates and components. See how to exploit the Rails service frameworks to send emails, implement web services, and create dynamic, user-centric web-pages using built-in Javascript and Ajax support. There are extensive chapters on testing, deployment, and scaling. You'll see how easy it is to install Rails using your web server of choice (such as Apache or lighttpd) or using its own included web server. You'll be writing applications that work with your favorite database (MySQL, Oracle, Postgres, and more) in no time at all. You'll create a complete online store application in the extended tutorial section, so you'll see how a full Rails application is developed---iteratively and rapidly. Rails strives to honor the Pragmatic Programmer's "DRY Principle" by avoiding the extra work of configuration files and code annotations. You can develop in real-time: make a change, and watch it work immediately. Forget XML. Everything in Rails, from templates to control flow to business logic, is written in Ruby, the language of choice for programmers who like to get the job done well (and leave work ontime for a change). Rails is the framework of choice for the new generation of Web 2.0 developers. Agile Web Development with Rails is the book for that generation, written by Dave Thomas (Pragmatic Programmer and author of Programming Ruby) and David Heinemeier Hansson, who created Rails.
