ONE OF THE YEAR'S BEST BOOKS The Wall Street Journal • Slate • Kansas City Star • Flavorwire • Policy Mic • Buzzfeed “Necessary Errors is a very good novel, an enviably good one, and to read it is to relive all the anxieties and illusions and grand projects of one’s own youth.”—James Wood, The New Yorker The exquisite debut novel by the author of Overthrow that brilliantly captures the lives and romances of young expatriates in newly democratic Prague It’s October 1990. Jacob Putnam is young and full of ideas. He’s arrived a year too late to witness Czechoslovakia’s revolution, but he still hopes to find its spirit, somehow. He discovers a country at a crossroads between communism and capitalism, and a picturesque city overflowing with a vibrant, searching sense of possibility. As the men and women Jacob meets begin to fall in love with one another, no one turns out to be quite the same as the idea Jacob has of them—including Jacob himself. Necessary Errors is the long-awaited first novel from literary critic and journalist Caleb Crain. Shimmering and expansive, Crain’s prose richly captures the turbulent feelings and discoveries of youth as it stretches toward adulthood—the chance encounters that grow into lasting, unforgettable experiences and the surprises of our first ventures into a foreign world—and the treasure of living in Prague during an era of historic change.

The Future of Numerical Computing Written by one of the foremost experts in high-performance computing and the inventor of Gustafson’s Law, The End of Error: Unum Computing explains a new approach to computer arithmetic: the universal number (unum). The unum encompasses all IEEE floating-point formats as well as fixed-point and exact integer arithmetic. This new number type obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power. A Complete Revamp of Computer Arithmetic from the Ground Up Richly illustrated in color, this groundbreaking book represents a fundamental change in how to perform calculations automatically. It illustrates how this novel approach can solve problems that have vexed engineers and scientists for decades, including problems that have been historically limited to serial processing. Suitable for Anyone Using Computers for Calculations The book is accessible to anyone who uses computers for technical calculations, with much of the book only requiring high school math. The author makes the mathematics interesting through numerous analogies. He clearly defines jargon and uses color-coded boxes for mathematical formulas, computer code, important descriptions, and exercises.

This 1991 book is a major theoretical integration of several previously isolated literatures looking at human error in major accidents.
