Book Description
'A gripping new drama in science ... if you want to understand how the concept of life is changing, read this' Professor Andrew Briggs, University of Oxford When Darwin set out to explain the origin of species, he made no attempt to answer the deeper question: what is life? For generations, scientists have struggled to make sense of this fundamental question. Life really does look like magic: even a humble bacterium accomplishes things so dazzling that no human engineer can match it. And yet, huge advances in molecular biology over the past few decades have served only to deepen the mystery. So can life be explained by known physics and chemistry, or do we need something fundamentally new? In this penetrating and wide-ranging new analysis, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it lacks a name, a domain where computing, chemistry, quantum physics and nanotechnology intersect. At the heart of these diverse fields, Davies explains, is the concept of information: a quantity with the power to unify biology with physics, transform technology and medicine, and even to illuminate the age-old question of whether we are alone in the universe. From life's murky origins to the microscopic engines that run the cells of our bodies, The Demon in the Machine is a breath-taking journey across the landscape of physics, biology, logic and computing. Weaving together cancer and consciousness, two-headed worms and bird navigation, Davies reveals how biological organisms garner and process information to conjure order out of chaos, opening a window on the secret of life itself.

Book Description
This book tells the story of the early modern astronomer Johannes Kepler’s Somnium, which has been regarded by science historians and literary critics alike as the first true example of science fiction. Kepler began writing his complex and heavily-footnoted tale of a fictional Icelandic astronomer as an undergraduate and added to it throughout his life. The Somnium fuses supernatural and scientific models of the cosmos through a satirical defense of Copernicanism that features witches, lunar inhabitants, and a daemon who speaks in the empirical language of modern science. Swinford’s looks at the ways that Kepler’s Somnium is influenced by the cosmic dream, a literary genre that enjoyed considerable popularity among medieval authors, including Geoffrey Chaucer, Dante, John of Salisbury, Macrobius, and Alan of Lille. He examines the generic conventions of the cosmic dream, also studying the poetic and theological sensibilities underlying the categories of dreams formulated by Macrobius and Artemidorus that were widely used to interpret specific symbols in dreams and to assess their overall reliability. Swinford develops a key claim about the form of the Somnium as it relates to early science: Kepler relies on a genre that is closely connected to a Ptolemaic, or earth-centered, model of the cosmos as a way of explaining and justifying a model of the cosmos that does not posit the same connections between the individual and the divine that are so important for the Ptolemaic model. In effect, Kepler uses the cosmic dream to describe a universe that cannot lay claim to the same correspondences between an individual’s dream and the order of the cosmos understood within the rules of the genre itself. To that end, Kepler’s Somnium is the first example of science fiction, but the last example of Neoplatonic allegory.

Book Description
Daniel Suarez’s New York Times bestselling debut high-tech thriller is “so frightening even the government has taken note” (Entertainment Weekly). Daemons: computer programs that silently run in the background, waiting for a specific event or time to execute. They power almost every service. They make our networked world possible. But they also make it vulnerable... When the obituary of legendary computer game architect Matthew Sobol appears online, a previously dormant daemon activates, initiating a chain of events that begins to unravel our interconnected world. This daemon reads news headlines, recruits human followers, and orders assassinations. With Sobol’s secrets buried with him, and as new layers of his daemon are unleashed, it’s up to Detective Peter Sebeck to stop a self-replicating virtual killer before it achieves its ultimate purpose—one that goes far beyond anything Sebeck could have imagined...

Book Description
A Guide to Kernel Exploitation: Attacking the Core discusses the theoretical techniques and approaches needed to develop reliable and effective kernel-level exploits, and applies them to different operating systems, namely, UNIX derivatives, Mac OS X, and Windows. Concepts and tactics are presented categorically so that even when a specifically detailed vulnerability has been patched, the foundational information provided will help hackers in writing a newer, better attack; or help pen testers, auditors, and the like develop a more concrete design and defensive structure.The book is organized into four parts. Part I introduces the kernel and sets out the theoretical basis on which to build the rest of the book. Part II focuses on different operating systems and describes exploits for them that target various bug classes. Part III on remote kernel exploitation analyzes the effects of the remote scenario and presents new techniques to target remote issues. It includes a step-by-step analysis of the development of a reliable, one-shot, remote exploit for a real vulnerabilitya bug affecting the SCTP subsystem found in the Linux kernel. Finally, Part IV wraps up the analysis on kernel exploitation and looks at what the future may hold. - Covers a range of operating system families — UNIX derivatives, Mac OS X, Windows - Details common scenarios such as generic memory corruption (stack overflow, heap overflow, etc.) issues, logical bugs and race conditions - Delivers the reader from user-land exploitation to the world of kernel-land (OS) exploits/attacks, with a particular focus on the steps that lead to the creation of successful techniques, in order to give to the reader something more than just a set of tricks

Book Description
Parallel Virtual Machine (PVM) and Message Passing Interface (MPI) are the most frequently used tools for programming according to the message passing paradigm, which is considered one of the best ways to develop parallel appli- tions. This volume comprises 50 revised contributions presented at the Eighth - ropean PVM/MPI Users’ Group Meeting, which was held on Santorini (Thera), Greece,23–26September2001.TheconferencewasorganizedbytheDepartment of Informatics and Telecommunications, University of Athens, Greece. This conference has been previously held in Balatofured, ̈ Hungary (2000), Barcelona, Spain (1999), Liverpool, UK (1998), and Krakow, Poland (1997). The ?rst three conferences were devoted to PVM and were held at the TU Munich, Germany (1996), the ENS Lyon, France (1995), and the University of Rome (1994). This conference has become a forum for users and developers of PVM, MPI, and other message passing environments. Interaction between these groups has proved to be very useful for developing new ideas in parallel computing and for applying some of those already existent to new practical ?elds. The main topics of the meeting were evaluation and performance of PVM and MPI, extensions and improvements to PVM and MPI, algorithms using the message passing paradigm,andapplicationsinscienceandengineeringbasedonmessagepassing. The conference included one tutorial on MPI and 9 invited talks on advances in MPI, cluster computing, network computing, Grid computing, and parallel programming and programming systems. These proceedings contain papers on the 46 oral presentations together with 4 poster presentations.
