… The book the National Security Agency wanted never to be published." –Wired Magazine "…monumental… fascinating… comprehensive… the definitive work on cryptography for computer programmers…" –Dr. Dobb's Journal"…easily ranks as one of the most authoritative in its field." —PC Magazine"…the bible of code hackers." –The Millennium Whole Earth CatalogThis new edition of the cryptography classic provides you with a comprehensive survey of modern cryptography. The book details how programmers and electronic communications professionals can use cryptography—the technique of enciphering and deciphering messages-to maintain the privacy of computer data. It describes dozens of cryptography algorithms, gives practical advice on how to implement them into cryptographic software, and shows how they can be used to solve security problems. Covering the latest developments in practical cryptographic techniques, this new edition shows programmers who design computer applications, networks, and storage systems how they can build security into their software and systems. What's new in the Second Edition? * New information on the Clipper Chip, including ways to defeat the key escrow mechanism * New encryption algorithms, including algorithms from the former Soviet Union and South Africa, and the RC4 stream cipher * The latest protocols for digital signatures, authentication, secure elections, digital cash, and more * More detailed information on key management and cryptographic implementations

    When Nick opens the door to his attic room, he's hit in the head by a toaster. That's just the beginning of his weird experiences with the old junk stored up there. After getting rid of the odd antiques in a garage sale, Nick befriends some local kids-Mitch, Caitlin, and Vincent-and they discover that all of the objects have extraordinary properties. What's more, Nick figures out that the attic is a strange magnetic vortex, which attracts all sorts of trouble. It's as if the attic itself has an intelligence . . . and a purpose.Ultimately Nick learns that the genius Nikola Tesla placed the items-his last inventions-in the attic as part of a larger plan that he mathematically predicted. Nick and his new friends must retrieve everything that was sold at the garage sale and keep it safe. But the task is fraught with peril-in addition to the dangers inherent in Tesla's mysterious and powerful creations, a secret society of physicists, the Accelerati, is determined to stop Nick and alter destiny to achieve its own devious ends. It's a lot for a guy to handle, especially when he'd much rather fly under the radar as the new kid in town.

    Full of insights, arguments and philosophical perspectives, the book covers an amazing array of topics. Beginning in antiquity with Democritus, it progresses through logic and set theory, computability and complexity theory, quantum computing, cryptography, the information content of quantum states and the interpretation of quantum mechanics. There are also extended discussions about time travel, Newcomb's Paradox, the anthropic principle and the views of Roger Penrose. Aaronson's informal style makes this fascinating book accessible to readers with scientific backgrounds, as well as students and researchers working in physics, computer science, mathematics and philosophy.

    With this hands-on guide, you'll learn how to write effective, idiomatic Python code by leveraging its best and possibly most neglected features. Author Luciano Ramalho takes you through Python's core language features and libraries, and shows you how to make your code shorter, faster, and more readable at the same time.Many experienced programmers try to bend Python to fit patterns they learned from other languages, and never discover Python features outside of their experience. With this book, those Python programmers will thoroughly learn how to become proficient in Python 3.This book covers:Python data model: understand how special methods are the key to the consistent behavior of objectsData structures: take full advantage of built-in types, and understand the text vs bytes duality in the Unicode ageFunctions as objects: view Python functions as first-class objects, and understand how this affects popular design patternsObject-oriented idioms: build classes by learning about references, mutability, interfaces, operator overloading, and multiple inheritanceControl flow: leverage context managers, generators, coroutines, and concurrency with the concurrent.futures and asyncio packagesMetaprogramming: understand how properties, attribute descriptors, class decorators, and metaclasses work"

    Medium looks. Medium grades. Medium parents who barely notice him. With a list of phobias that could make anyone crazy, Mack never would have guessed that he is destined for a more-than-medium life.And then, one day, something incredibly strange happens to Mack. A three-thousand-year-old man named Grimluk appears in the boys' bathroom to deliver some startling news: Mack is one of the Magnificent Twelve, called the Magnifica in ancient times, whatever that means. An evil force is on its way, and it's up to Mack to track down eleven other twelve-year-olds in order to stop it. He must travel across the world to battle the wicked Pale Queen's dangerous daughter, Ereskigal--also known as Risky. But Risky sounds a little scary, and Mack doesn't want to be a hero. Will he answer the call?A laugh-out-loud story filled with excitement and magic, "The Magnificent Twelve: The Call" is the first book in bestselling author Michael Grant's hilarious new fantasy adventure series.

    We have Mindstorms to thank for that. In this book, pioneering computer scientist Seymour Papert uses the invention of LOGO, the first child-friendly programming language, to make the case for the value of teaching children with computers. Papert argues that children are more than capable of mastering computers, and that teaching computational processes like de-bugging in the classroom can change the way we learn everything else. He also shows that schools saturated with technology can actually improve socialization and interaction among students and between students and teachers.
