Newbery medalist Jerry Spinelli has penned his early autobiography with all the warmth, humor, and drama of his best-selling fiction. And don't miss the author's highly anticipated new novel, Dead Wednesday! "A master of those embarrassing, gloppy, painful, and suddenly wonderful things that happen on the razor's edge between childhood and full-fledged adolescence" --The Washington Post From first memories through high school, including first kiss, first punch, first trip to the principal's office, and first humiliating sports experience, this is not merely an account of a highly unusual childhood. Rather, like Spinelli's fiction, its appeal lies in the accessibility and universality of his life. Entertaining and fast-paced, this is a highly readable memoir-- a must-have for Spinelli fans of all ages.
The World of DJs and the Turntable Culture

(Book). Step behind the wheels of steel and into the world of professional DJs. The World of DJs and the Turntable Culture is the only book that clearly and thoroughly teaches the tools, technologies and techniques of contemporary DJing. It also goes further, exploring the culture, history and aesthetics of hip-hop, dance music and turntablism. Souvignier traces the turntable's evolution from consumer playback device into a professional musical instrument, right up to the latest CD scratching decks. He also traces the evolution of the DJ from selector and record announcer to producer/performer. This book features exclusive interviews with GrandWizzard Theodore (the inventor of scratching) and other superstars including DJ QBert, Rob Swift (X-ecutioners), Armand Van Helden and mash-up maven The Freelance Hellraiser. The wide ranging topics covered include a mechanical history of turntables and a DJ technology roundup; Alan Freed, Dick Clark and payola; John Cage's Cartridge Music; Grandmaster Flash; Jamaican sound systems; the rise and fall of disco; house, techno and garage music; a dictionary of scratches; and developing DJ skills. The World of DJs and the Turntable Culture includes hands-on chapters that explain the basic tools DJs use, teaches the fundamental techniques, and explores the creative possibilities for DJs. There is a special focus on state-of-the-art gear, spotlighting the most exciting, cutting-edge features.
Essential Logic for Computer Science

An introduction to applying predicate logic to testing and verification of software and digital circuits that focuses on applications rather than theory. Computer scientists use logic for testing and verification of software and digital circuits, but many computer science students study logic only in the context of traditional mathematics, encountering the subject in a few lectures and a handful of problem sets in a discrete math course. This book offers a more substantive and rigorous approach to logic that focuses on applications in computer science. Topics covered include predicate logic, equation-based software, automated testing and theorem proving, and large-scale computation. Formalism is emphasized, and the book employs three formal notations: traditional algebraic formulas of propositional and predicate logic; digital circuit diagrams; and the widely used partially automated theorem prover, ACL2, which provides an accessible introduction to mechanized formalism. For readers who want to see formalization in action, the text presents examples using Proof Pad, a lightweight ACL2 environment. Readers will not become ALC2 experts, but will learn how mechanized logic can benefit software and hardware engineers. In addition, 180 exercises, some of them extremely challenging, offer opportunities for problem solving. There are no prerequisites beyond high school algebra. Programming experience is not required to understand the book's equation-based approach. The book can be used in undergraduate courses in logic for computer science and introduction to computer science and in math courses for computer science students.
