Book Description
Data in all domains is getting bigger. How can you work with it efficiently? Recently updated for Spark 1.3, this book introduces Apache Spark, the open source cluster computing system that makes data analytics fast to write and fast to run. With Spark, you can tackle big datasets quickly through simple APIs in Python, Java, and Scala. This edition includes new information on Spark SQL, Spark Streaming, setup, and Maven coordinates. Written by the developers of Spark, this book will have data scientists and engineers up and running in no time. You’ll learn how to express parallel jobs with just a few lines of code, and cover applications from simple batch jobs to stream processing and machine learning. Quickly dive into Spark capabilities such as distributed datasets, in-memory caching, and the interactive shell Leverage Spark’s powerful built-in libraries, including Spark SQL, Spark Streaming, and MLlib Use one programming paradigm instead of mixing and matching tools like Hive, Hadoop, Mahout, and Storm Learn how to deploy interactive, batch, and streaming applications Connect to data sources including HDFS, Hive, JSON, and S3 Master advanced topics like data partitioning and shared variables

Book Description
Fishing for Lightning gathers together acclaimed poet and critic Sarah Holland-Batt's celebrated columns on contemporary Australian poetry. In fifty illuminating and lively short essays on fifty poets, Holland-Batt offers a masterclass in how to read and love poetry, opening up the music of language, form, and poetic technique in her casual and conversational yet deeply intelligent style. From the villanelle to the verse novel, the readymade and the remix to the sonnet, Holland-Batt's essays range across the breadth of contemporary poetry, but also delve into the richness of poetic and literary history, connecting the contemporary to the ancient. Dazzling in its erudition, but always accessible and entertaining, Fishing for Lightning convinces us of the power of poetry to change our lives.

Book Description
A fresh look at electricity and its powerful role in life on Earth When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices—or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical. The story of how we came to understand electricity’s essential role in all life is rooted in our observations of its influences on the body—influences governed by the body’s central nervous system. Spark explains the science of electricity from this fresh, biological perspective. Through vivid tales of scientists and individuals—from Benjamin Franklin to Elon Musk—Timothy Jorgensen shows how our views of electricity and the nervous system evolved in tandem, and how progress in one area enabled advancements in the other. He explains how these developments have allowed us to understand—and replicate—the ways electricity enables the body’s essential functions of sight, hearing, touch, and movement itself. Throughout, Jorgensen examines our fascination with electricity and how it can help or harm us. He explores a broad range of topics and events, including the Nobel Prize–winning discoveries of the electron and neuron, the history of experimentation involving electricity’s effects on the body, and recent breakthroughs in the use of electricity to treat disease. Filled with gripping adventures in scientific exploration, Spark offers an indispensable look at electricity, how it works, and how it animates our lives from within and without.

Book Description
This "utterly spectacular" book weighs the impact modern medical technology has had on the author's life against the social and environmental costs inevitably incurred by the mining that makes such innovation possible (Rachel Louise Snyder, author of No Visible Bruises). What if a lifesaving medical device causes loss of life along its supply chain? That's the question Katherine E. Standefer finds herself asking one night after being suddenly shocked by her implanted cardiac defibrillator. In this gripping, intimate memoir about health, illness, and the invisible reverberating effects of our medical system, Standefer recounts the astonishing true story of the rare diagnosis that upended her rugged life in the mountains of Wyoming and sent her tumbling into a fraught maze of cardiology units, dramatic surgeries, and slow, painful recoveries. As her life increasingly comes to revolve around the internal defibrillator freshly wired into her heart, she becomes consumed with questions about the supply chain that allows such an ostensibly miraculous device to exist. So she sets out to trace its materials back to their roots. From the sterile labs of a medical device manufacturer in southern California to the tantalum and tin mines seized by armed groups in the Democratic Republic of the Congo to a nickel and cobalt mine carved out of endemic Madagascar jungle, Lightning Flowers takes us on a global reckoning with the social and environmental costs of a technology that promises to be lifesaving but is, in fact, much more complicated. Deeply personal and sharply reported, Lightning Flowers takes a hard look at technological mythos, healthcare, and our cultural relationship to medical technology, raising important questions about our obligations to one another, and the cost of saving one life.
