The Christmas List. Der Weihnachtswunsch, englische Ausgabe Simon & Schuster UK

Książki / Literatura obcojęzyczna

A heartwarming and inspirational Christmas novel in the tradition of The Christmas Box, Grace, The Gift , and Finding Noel . The New York Times bestselling author of The Christmas Box and The Walk series returns with a holiday novel of hope, love, and redemption.§Dear Reader, §When I was in seventh grade, my English teacher, Mrs. Johnson, gave our class the intriguing (if somewhat macabre) assignment of writing our own obituaries. Oddly, I don't remember much of what I wrote about my life, but I do remember how I died: in first place on the final lap of the Daytona 500. At the time, I hadn't considered writing as an occupation, a field with a remarkably low on-the-job casualty rate. §What intrigues me most about Mrs. Johnson's assignment is the opportunity she gave us to confront our own legacy. How do we want to be remembered? That question has motivated our species since the beginning of time: from building pyramids to putting our names on skyscrapers. §As I began to write this book, I had two objectives: First, I wanted to explore what could happen if someone read their obituary before they died and saw, firsthand, what the world really thought of them. Their legacy. §Second, I wanted to write a Christmas story of true redemption. One of my family's holiday traditions is to see a local production of Charles Dickens's A Christmas Carol . I don't know how many times I've seen it (perhaps a dozen), but it still thrills me to see the change that comes over Ebenezer Scrooge as he transforms from a dull, tight-fisted miser into a penitent, "giddy-as-aschoolboy" man with love in his heart. I always leave the show with a smile on my face and a resolve to be a better person. That's what I wanted to share with you, my dear readers, this Christmas -- a holiday tale to warm your season, your homes, and your hearts. §Merry Christmas

Literatura faktu

'Only with the greatest of simplifications, for the sake of convenience, can we say Africa. In reality, except as a geographical term, Africa doesn't exist'. Ryszard Kapuscinski has been writing about the people of Africa throughout his career. In a study that avoids the official routes, palaces and big politics, he sets out to create an account of post-colonial Africa seen at once as a whole and as a location that wholly defies generalised explanations. It is both a sustained meditation on the mosaic of peoples and practises we call 'Africa', and an impassioned attempt to come to terms with humanity itself as it struggles to escape from foreign domination, from the intoxications of freedom, from war and from politics as theft. The Beginning: Collision, Ghana 1958 More than anything, one is struck by the light. Light everywhere. Brightness everywhere. Everywhere, the sun. Just yesterday, an autumnal London was drenched in rain. The airplane drenched in rain. A cold, wind, darkness. But here, from the morning

Distributed network protocols for anonymous stations in cooperative and noncooperative settings - 2619308978

Distributed network protocols for anonymous stations in cooperative and noncooperative settings Politechnika Gdańska

INFORMATYKA

This work studies the effects of station anonymity and/or noncooperative (selfish) station behavior upon the design and performance of selected distributed network protocols. A set of stations interconnected by a computer network are assumed to be engaged in a collective activity for which some inter-station consistency is required. The considered protocols relate to group communication (where message delivery in agreed order is required), random multiple access over a single channel (where collision avoidance is required), and packet forwarding (where maintenance of end-to-end paths is required). Design of distributed protocols for anonymous stations permits to dispense with costly authentication mechanisms, and provides a "security lower bound" for systems in which station identities are relied upon. Modeling of noncooperative settings (where stations are allowed to behave selfishly) is justified in view of the increased autonomy and user configurability of today's network components; at the same time, as a departure from the traditional engineering paradigm, it opens up interesting areas of networking research. In Chapter 2, two agreed order multicast protocols are proposed for anonymous stations in a cooperative setting. Both are LAN-oriented i.e., designed to yield high group throughput by exploiting the natural synchronism of single-broadcast transmission media. A faulty communication environment is assumed with occasional reception misses - failures by one or more stations to receive a message. The Distributed Precedence Graph (DPG) protocol is network-independent in that multicast and reception primitives clearly define a protocol-to-network interface, and missed message recovery is separated from message ordering. In contrast, the Jamming Protocol (JP) is network-dependent and exploits in a novel way the "ideal synchronism" of LAN broadcast to couple missed message recovery and message ordering. Both proposed protocols are insensitive to membership control mechanisms and do without the knowledge of station identities. Even so, they compare favorably with existing agreed order multicast protocols like LANSIS or TOTEM, as demonstrated by the analysis of logicaltime properties and simulation of stochastic performance. Chapters 3 through 5 are devoted to game-theoretic analysis of random access MAC-layer protocols in a noncooperative setting. Chapter 3 deals with CSMA/CA, the multiple access mechanism of the IEEE 802.11 MAC protocol. It is argued that in an ad hoc wireless LAN, CSMA/CA is vulnerable to a selfish backoff attack consisting in systematic selection of short backoff times. Network performance under a backoff attack is evaluated via extension of Bianchi's Markovian approximation, as well as using more accurate models. A sufficient condition of solvability is given and a game-theoretic analysis is carried out with stations' bandwidth shares regarded as payoffs. Launching a backoff attack is established as a strictly dominating action, the payoff structure of the resulting one-shot CSMA/CA game being similar to a multiplayer Prisoners' Dilemma (with a unique and Pareto non-optmal Nash equilibrium). The notion of a Nash capacity is introduced to show that selfish station behavior reduces the achievable bandwidth utilization roughly by half compared with a cooperative setting. Incentive-based discouragement of backoff attacks is proposed in Chapter 4 using the concept of a repeated CSMA/CA game, where a station is allowed to reconfigure its CSMA/CA mechanism based upon past payoffs. Assuming that most stations are interested in enforcing cooperative behavior of the other stations, a satisfactory equilibrium play is shown possible. In particular, a selfish station can be expected to incline to honest play for fear of the other stations inclining to selfish play. This idea is elaborated upon and gives rise to two proposed strategies of playing the repeated CSMA/CA game, called Cooperation via Randomized Inclination to Selfish Play (CRISP) and Selfish Play to Elicit Live-and-Let-live (SPELL). By exploiting another property of the one-shot CSMA/CA game, called coarse profile observability, CRISP and SPELL are shown to asymptotically achieve Pareto optimality and the related Nash equilibrium becomes subgame perfect. It is shown how to extend the proposed strategies if some stations disengage the CSMA/CA backoff scheme. Chapter 4 concludeswith a discussion of QoS-sensitive station behavior, in which case the CSMA/CA game may change from a Prisoners' Dilemma into a form of a queuing game. Selfish behavior of CSMA/CA stations studied in Chapters 3 and 4 only affects specific protocol parameters, leaving the very principle of contention unchanged. In Chapter 5 we look at a slightly more general model of single-channel contention. In the proposed framework, the MAC protocol proceeds in cycles, each of which accommodates the stations' requests to transmit. This subsumes various existing random token-like protocols e.g., CSMA/CA, Random Token, slotted ALOHA, and HIPERLAN/1. A selection configuration determines how the requests are placed, whereas a winner policy decides the winner of a contention. It is argued that while the winner policy must be agreed upon by all the stations, the selection configuration is entirely within a station's discretion. For a wide class of winner policies, called Random Token with Extraneous Collision Detection (RT/ECD), the notions of verifiability and viability are introduced to factor out brute-force selfish behavior, and shown to lead to two interesting winner policies, RT/ECD-0 and RT/ECD--. The resulting games are found to be a multiplayer Prisoners' Dilemma and an anti-coordination game, respectively. Related repeated games are again found to potentially lead to cooperative behavior. In Chapter 6, selfishness considerations are extended to the network layer of a mobile ad hoc network (MANET). Each MANET station generates source packets and also is supposed to forward transit packets for pairs of stations currently out of each other's reception range. It is argued that forwarding transit packets becomes a dual liability: it shortens the station's battery life "in exchange for" sacrificing a portion of the channel bandwidth that could be used for source packets. Under the introduced packet anonymity model (no packet reveals its source station except at destination), undetectable selfish manipulation of the local congestion controls is possible. The issue is addressed in a noncooperative game-theoretic framework: each MANET station selects its own strategy (congestion control settings) at will, so as to maximize some defined payoff (a combination of source packet throughput and a reputation measure). For a class of Drop-and-Throttle (D&T) congestion control mechanisms, a generic model is formulated, whereby a station adjusts its D&T threshold in response to the other stations' adjusted thresholds; this model is subsequently translated into a simple extensive-form game. Types of reachable Nash equilibria are discussed and the notion of robustness of a Nash equilibrium is introduced. Finally, a novel packet forwarding protocol called Fair Forwarding with Forced Transmissions (F3T) is presented, which, if properly configured, leads to a desirable type of Nash equilibrium.

Nightmares of Terror Resource Publications (CA)

Książki / Literatura obcojęzyczna

Nightmares of Terror, continuing the saga that began in Days of Purgatory, is set in and around Dodge City in 1882. Several characters are having their sleep disturbed by dreams that are flares from the past or harbingers of the future. Deacon Coburn, flint-eyed and tenderhearted, aids others and comes to terms with hardscrabble troubles by applying gritty faith. An outlaw is on the rampage; his life has been violent and he's realizing that hell is a real place. A former prostitute is seeking a new life, while a teenager stretches her wings. One strong man is having a crisis of faith; another is in a mess of troubles not of his making. Two women are expecting and due at roughly the same time. A Texas cattleman arrives in the Queen of the Cowtowns to conclude a business deal, which unbeknownst to him, forces a onetime slave to come face to face with a seedy episode from bygone days. All these threads are woven together in a compelling narrative in which the supernatural is commonplace and real. An overarching theme is voiced by Eliza Weitzel: ""Faith is all about having confidence that whatever will be will be, and by God's grace we have the hope that he sustains and supports us no matter what."" ""As a youngster, I grew up toward the end of an era of classic Westerns and remember being mesmerized by such heroes as Matt Dillon (Gunsmoke), Lucas McCain (The Rifleman), and Jim Crown (Cimarron Strip). Abell adds one more to this list of emulate-able heroes by taking us back to the frontier trails and streets of the 19th century, and introducing us to Deacon Coburn. With a heart toward heaven and boots firmly grounded in the dust of the Old West, Coburn is a light of hope and redemption to troubled souls, even while haunted by his past. Picking up where Echoes of Evil leaves off, Nightmares of Terror wrestles with the questions of faith that many feel, yet most are afraid to ask."" --Timothy W. Fisher, author of Where Heaven Meets Earth ""There are no signs of flagging or fatigue in the fourth installment of the Deacon Coburn series. Nightmares of Terror continues Abell's starkly real examination of spirituality and mysticism meeting at the crossroads of faith in the unknowable. Each character who is plagued by the titular nightmares must face their deepest fears, and these supernatural touchstones are often premonitions or omens of calamity. Upheaval and change are abundant as character arcs and plotlines conclude only to reveal new beginnings. A tautly-paced tale that had me tearing through the final forty pages in breathless anticipation and fearful wonder."" --William D. Hastings, author of Behind Prison Walls Ken R. Abell resides in New Mexico with his wife, Anita. They serve the Overcomers Program at Navajo BIC Mission. Among other projects, he is writing the fifth installment of this western epic. His work can be found at www.wantedman.org or www.danceswithcorn.com.
