This practical guide shows how Apache ZooKeeper helps you manage distributed systems, so you can focus mainly on application logic. Even with ZooKeeper, implementing coordination tasks is not trivial, but this book provides good practices to give you a head start, and points out caveats that developers and administrators alike need to watch for along the way.In three separate sections, ZooKeeper contributors Flavio Junqueira and Benjamin Reed introduce the principles of distributed systems, provide ZooKeeper programming techniques, and include the information you need to administer this service.Learn how ZooKeeper solves common coordination tasksExplore the ZooKeeper API’s Java and C implementations and how they differUse methods to track and react to ZooKeeper state changesHandle failures of the network, application processes, and ZooKeeper itselfLearn about ZooKeeper’s trickier aspects dealing with concurrency, ordering, and configurationUse the Curator high-level interface for connection managementBecome familiar with ZooKeeper internals and administration tools

    Landing on the Moon presented an ideal goal all on its own, but the government’s urgency in designing the Apollo program was actually brought about by the Soviet Union, which spent much of the 1950s leaving the United States in its dust (and rocket fuel). In 1957, at a time when people were concerned about communism and nuclear war, many Americans were dismayed by news that the Soviet Union was successfully launching satellites into orbit. Among those concerned was President Dwight D. Eisenhower, whose space program was clearly lagging a few years behind the Soviets’ space program. From 1959-1963, the United States worked toward putting satellites and humans into orbit via the Mercury program, but Eisenhower’s administration was already designing plans for the Apollo program by 1960, a year before the first Russian orbited the Earth and two years before John Glenn became the first American to orbit the Earth. On May 25, 1961, President John F. Kennedy addressed Congress and asked the nation to “commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth.” Given America’s inability to even put a man in orbit yet, this seemed like an overly ambitious goal, and it isn’t even clear that Kennedy himself believed it possible; after all, he was reluctant to meet NASA Administrator James E. Webb’s initial funding requests. As Apollo 11’s name suggests, there were actually a number of Apollo missions that came before, many of which included testing the rockets and different orbital and lunar modules in orbit. In fact, it wasn’t until Apollo 8 that a manned vehicle was sent towards the Moon and back, and before that mission, the most famous Apollo mission was Apollo 1, albeit for all the wrong reasons. Over the decade, NASA would spend tens of billions on the Apollo missions, the most expensive peacetime program in American history to that point, and even though Apollo 11 was only one of almost 20 Apollo missions, it was certainly the crown jewel. only one of nearly 20 Apollo missions conducted by NASA. And to make Apollo 11 a success, it would take nearly a decade of planning by government officials, hard work by NASA scientists, intense training by the astronauts, and several missions preceding Apollo 11. It also cost over $20 billion, making the Apollo program the most expensive peacetime program in American history at the time. Apollo 12 successfully landed astronauts on the Moon just a few months after Apollo 11’s successful mission. Apollo 12 was actually more successful than Apollo 11 from the standpoint of fulfilling the mission objectives, but it was naturally overshadowed since it did not come first. Another reason Apollo 12 is mostly forgotten today can be credited to the dramatic and fateful Apollo 13 mission, which took twists and turns nobody could have predicted when it launched on April 11, 1970. Apollo 13’s mission was to land on the Moon near the Fra Mauro highlands, which were hills that had somehow formed in the middle of a huge crater tens of miles wide. The mission was supposed to test for seismic activity and take samples to analyze the crater and try to find an explanation for the formation of the hills.

    Among the many modern marvels that gave the North an advantage was the telegraph, which Lincoln used to stay connected to the forces in the field in almost real time.No leader in history had ever possessed such a powerful tool to gain control over a fractious situation. An eager student of technology, Lincoln (the only president to hold a patent) had to learn to use the power of electronic messages. Without precedent to guide him, Lincoln began by reading the telegraph traffic among his generals. Then he used the telegraph to supplement his preferred form of communication—meetings and letters. He did not replace those face-to-face interactions. Through this experience, Lincoln crafted the best way to guide, reprimand, praise, reward, and encourage his commanders in the field.Mr. Lincoln's T-Mails tells a big story within a small compass. By paying close attention to Lincoln's "lightning messages," we see a great leader adapt to a new medium. No reader of this work of history will be able to miss the contemporary parallels. Watching Lincoln carefully word his messages—and follow up on those words with the right actions—offers a striking example for those who spend their days tapping out notes on computers and BlackBerrys.An elegant work of history, Mr. Lincoln's T-Mails is an instructive example of timeless leadership lessons.

    Adam Neumann, an immigrant determined to make his fortune in the United States, landed on the idea of repurposing surplus New York office space for the burgeoning freelance class. Over the course of ten years, WeWork attracted billions of dollars from some of the most sought-after investors in the world, while spending it to build a global real estate empire that he insisted was much more than that: an organization that aspired to nothing less than "elevating the world's consciousness."Moving between New York real estate, Silicon Valley venture capital, and the very specific force field of spirituality and ambition erected by Adam Neumann himself, Billion Dollar Loser lays bare the internal drama inside WeWork. Based on more than two hundred interviews, this book chronicles the breakneck speed at which WeWork’s CEO built and grew his company along with Neumann’s relationship to a world of investors, including Masayoshi Son of Softbank, who fueled its chaotic expansion into everything from apartment buildings to elementary schools.Culminating in a day-by-day account of the five weeks leading up to WeWork’s botched IPO and Neumann’s dramatic ouster, Wiedeman exposes the story of the company’s desperate attempt to secure the funding it needed in the final moments of a decade defined by excess. Billion Dollar Loser is the first book to indelibly capture the highly leveraged, all-blue-sky world of American business in President Trump’s first term, and also offers a sober reckoning with its fallout as a new era begins.

    Even all by themselves, the titles of Patricia Lockwood's poems reveal the sort of surreal, enigmatic, rhetorically-elongated world her sensibility inhabits effortlessly: "When We Move Away From Here, You'll See A Clean Square of Paper Where His Picture Hung," "The Cartoon's Mother Builds a House in Hammerspace," "The Front Half and the Back Half of a Horse in Conversation," "Children With Lamps Pouring Out of Their Foreheads," and the inimitable "Killed With an Apple Corer, She Asks What Does That Make Me."

    His profound and poetic speeches are famous around the world, evidence of the greatness of American’s most beloved leader. But did you know that the sixteenth president of the United States was also a backwoods hillbilly from America’s western frontier, with a Kentucky accent so thick you could cut it? Or that he liked wrestling matches, dirty jokes, and had a reputation for telling hilarious, R-rated stories that weren’t suitable for mixed company? From his childhood working as a virtual slave for an abusive father, to sailing a river raft to New Orleans, to the Illinois General Assembly, Congress, and the White House, the story of Abraham Lincoln’s life is the story of America. He mourned the deaths of almost everyone he loved, endured marriage to a wife whose mental health issues made her a domestic abuser, and lost more elections than he won. But Abraham Lincoln believed in one thing above all: that everyone deserved a fair shot at the American dream. Why did John Wilkes Booth really shoot Abraham Lincoln? The truth is as shocking now as it was in 1865.

    A friend refers her to the mysterious Mr. Highground, who introduces her to four successful people. They show her how they transformed their businesses and their lives by determining how others view them and how they view themselves as both human beings and businesspeople. Each of the four represents a "type" in this schema - from the "relational/business" type who puts the relationship first but thinks strategically when the talk turns to business, to the "business/business" type, who avoids relationships unless they work to a business advantage. Templeton shows how understanding one's type allows one to showcase strengths while improving weak areas in this simple, easy-to-use guide to success in business and in life.

    Right?! Machine Learning is a branch of computer science that wants to stop programming computers using a detailed list of commands to follow blindly. Instead, their aim is to implement high-level routines that teach computers how to approach new and unknown problems – these are called algorithms. In practice, they want to give computers the ability to Learn and to Adapt. We can use these algorithms to obtain insights, recognize patterns and make predictions from data, images, sounds or videos we have never seen before – or even knew existed. Unfortunately, the true power and applications of today’s Machine Learning Algorithms remain deeply misunderstood by most people. Through this book I want fix this confusion, I want to shed light on the most relevant Machine Learning Algorithms used in the industry. I will show you exactly how each algorithm works, why it works and when you should use it.
