Book Description
Upgrade your programming language to more effectively handle high-frequency data Machine Learning and Big Data with KDB+/Q offers quants, programmers and algorithmic traders a practical entry into the powerful but non-intuitive kdb+ database and q programming language. Ideally designed to handle the speed and volume of high-frequency financial data at sell- and buy-side institutions, these tools have become the de facto standard; this book provides the foundational knowledge practitioners need to work effectively with this rapidly-evolving approach to analytical trading. The discussion follows the natural progression of working strategy development to allow hands-on learning in a familiar sphere, illustrating the contrast of efficiency and capability between the q language and other programming approaches. Rather than an all-encompassing “bible”-type reference, this book is designed with a focus on real-world practicality to help you quickly get up to speed and become productive with the language. Understand why kdb+/q is the ideal solution for high-frequency data Delve into “meat” of q programming to solve practical economic problems Perform everyday operations including basic regressions, cointegration, volatility estimation, modelling and more Learn advanced techniques from market impact and microstructure analyses to machine learning techniques including neural networks The kdb+ database and its underlying programming language q offer unprecedented speed and capability. As trading algorithms and financial models grow ever more complex against the markets they seek to predict, they encompass an ever-larger swath of data – more variables, more metrics, more responsiveness and altogether more “moving parts.” Traditional programming languages are increasingly failing to accommodate the growing speed and volume of data, and lack the necessary flexibility that cutting-edge financial modelling demands. Machine Learning and Big Data with KDB+/Q opens up the technology and flattens the learning curve to help you quickly adopt a more effective set of tools.

Book Description
AN INSTANT NEW YORK TIMES BESTSELLER "Provocative and appealing . . . well worth your extremely limited time." —Barbara Spindel, The Wall Street Journal The average human lifespan is absurdly, insultingly brief. Assuming you live to be eighty, you have just over four thousand weeks. Nobody needs telling there isn’t enough time. We’re obsessed with our lengthening to-do lists, our overfilled inboxes, work-life balance, and the ceaseless battle against distraction; and we’re deluged with advice on becoming more productive and efficient, and “life hacks” to optimize our days. But such techniques often end up making things worse. The sense of anxious hurry grows more intense, and still the most meaningful parts of life seem to lie just beyond the horizon. Still, we rarely make the connection between our daily struggles with time and the ultimate time management problem: the challenge of how best to use our four thousand weeks. Drawing on the insights of both ancient and contemporary philosophers, psychologists, and spiritual teachers, Oliver Burkeman delivers an entertaining, humorous, practical, and ultimately profound guide to time and time management. Rejecting the futile modern fixation on “getting everything done,” Four Thousand Weeks introduces readers to tools for constructing a meaningful life by embracing finitude, showing how many of the unhelpful ways we’ve come to think about time aren’t inescapable, unchanging truths, but choices we’ve made as individuals and as a society—and that we could do things differently.

Book Description
All of the medical, technological, and psychological advances of the twentieth century challenge “mere mortals” in Terese Svoboda's third book of poetry. In “Faust,” a mini-epic in five acts, the eponymous character of literary legend appears in the form of a woman, who redefines what being mortal means in light of the politics of the Third World, and gender. In contrast “Ptolemy's Rules for High School Reunions” explores what happens when you do without a pact with the devil. The gods—Greek and otherwise—also make appearances as a TV announcer in “Philomela,” in the basement with the plumber in “The Smell of Burning Pennies,” and in the dyslexic confusion between “Dog/God.” But it is not only the divine that charges the poems in Mere Mortals—sex also suffuses and reinvents key relationships. Readers of such wittily probing poems as “The Root of Father is Fat” and “Brassiere: Prison or Showcase?” will know why Philip Levine has described Svoboda as “one light-year from being the polite, loverly, workshop poet. ”Mere Mortals' poems first appeared in such magazines as the New Yorker, New York Times Magazine, Paris Review, and the American Poetry Review.

Book Description
NAMED A BEST BOOK OF THE YEAR BY ESQUIRE, THE IRISH TIMES AND THE TIMES LITERARY SUPPLEMENT A provocative history of men who were worshipped as gods that illuminates the connection between power and religion and the role of divinity in a secular age Ever since 1492, when Christopher Columbus made landfall in the New World and was hailed as a heavenly being, the accidental god has haunted the modern age. From Haile Selassie, acclaimed as the Living God in Jamaica, to Britain’s Prince Philip, who became the unlikely center of a new religion on a South Pacific island, men made divine—always men—have appeared on every continent. And because these deifications always emerge at moments of turbulence—civil wars, imperial conquest, revolutions—they have much to teach us. In a revelatory history spanning five centuries, a cast of surprising deities helps to shed light on the thorny questions of how our modern concept of “religion” was invented; why religion and politics are perpetually entangled in our supposedly secular age; and how the power to call someone divine has been used and abused by both oppressors and the oppressed. From nationalist uprisings in India to Nigerien spirit possession cults, Anna Della Subin explores how deification has been a means of defiance for colonized peoples. Conversely, we see how Columbus, Cortés, and other white explorers amplified stories of their godhood to justify their dominion over native peoples, setting into motion the currents of racism and exclusion that have plagued the New World ever since they touched its shores. At once deeply learned and delightfully antic, Accidental Gods offers an unusual keyhole through which to observe the creation of our modern world. It is that rare thing: a lyrical, entertaining work of ideas, one that marks the debut of a remarkable literary career.

Book Description
"Zade Holder has always been a free-spirited young woman, from a long dynasty of tarot-card readers, fortunetellers, and practitioners of magick. Growing up in a small town and never quite fitting in, Zade is determined to forge her own path. She leaves her home in Tennessee to break free from her overprotective mother Dela, the local resident spellcaster and fortuneteller. Zade travels to Las Vegas and uses supernatural powers to become part of a premiere magic show led by the infamous magician Charles Spellman. Zade fits right in with his troupe of artists and misfits. After all, when everyone is slightly eccentric, appearing 'normal' is much less important. Behind the scenes of this multimillion-dollar production, Zade finds herself caught in a love triangle with Mac, the show's good-looking but rough-around-the-edges technical director and Jackson, the tall, dark, handsome and charming bandleader. Zade's secrets and the struggle to choose between Mac or Jackson creates reckless tension during the grand finale of the show. Using Chaos magick, which is known for being unpredictable, she tests her abilities as a spellcaster farther than she's ever tried and finds herself at death's door. Her fate is left in the hands of a mortal who does not believe in a world of real magick, a fortuneteller who knew one day Zade would put herself in danger and a dagger with mystical powers"--Amazon.com
