Alan Burns – författare

Ada is the only ISO-standard, object-oriented, concurrent, real-time programming language. It is intended for use in large, long-lived applications where reliability and efficiency are essential, particularly real-time and embedded systems. In this book, Alan Burns and Andy Wellings give a thorough, self-contained account of how the Ada tasking model can be used to construct a wide range of concurrent and real-time systems. This is the only book that focuses on an in-depth discussion of the Ada tasking model. Following on from the authors' earlier title Concurrency in Ada, this book brings the discussion up to date to include the new Ada 2005 language and the recent advances in real-time programming techniques. It will be of value to software professionals and advanced students of programming alike: indeed every Ada programmer will find it essential reading and a primary reference work that will sit alongside the language reference manual.

Dreamerika!, Alan Burns’s fourth novel, first published in 1972, provides a satirical look at the Kennedy political dynasty, serving up an idiosyncratic hotch-potch of history that gives an old tragedy new meaning. For this book, Burns collected newspaper clippings, headlines, cartoons and photographs, cut them up, filed them and then interspersed them throughout his text to create a collage of contrasting effects.Presented in a fragmented form that reflects society’s disintegration, Dreamerika! fuses fact and dream, resulting in a surreal biography, an alternate history which lays bare the corruption and excesses of capitalism just as the heady idealism of the 1960s has begun to fade.

Babel, Alan Burns’s fourth critically acclaimed novel, contains all the hallmarks of the aleatoric style he helped to define – shot through with seemingly random newspaper headlines, poems, snatches of conversation and anecdote, which both heighten and undermine meaning, and characterized by extreme contrasts of mood and style and startling surrealist juxtapositions of images and ideas.By turns comic and tragic, tender and brutal, religious and blasphemous, the narrative rockets from London to the United States to Vietnam to interstellar space, familiar events are constantly fragmented and reset into new patterns, and ultimately Babel becomes a cautionary tale about the tragedy arising from attempting to build Utopia.

Ada* is unquestionably one of the most significant programming languages to emerge in the last decade. The manner of its inception and support by the US Department of Defense (DoD) ensures that it will be used extensively for the indefinite future in programming large and complex systems. The growing availability of compilers means that many organisations are already committed to using the language for sizable and significant applications. As a perhaps inevitable result of its design goals, Ada is a "large" language. It has Pascal-like control and type constructs; a mechanism for exception handling; a package structure for information hiding, decomposition and separate compilation; facilities for low-level programming; and a tasking model of concurrency. It is perhaps this last area that has generated most debate, criticism and disagreement. The purpose of this book is to review the tasking model in the light of the extensive analysis and comment which has appeared in the literature. The review is necessarily wide-ranging, including discussion of - Ada as a general purpose concurrent programming language, - Ada as a language for embedded and distributed systems, - implementation issues, with particular reference to distributed systems, - formal semantics, specification and verification, - proposed language modifications. By consolidating this discussion within the confines of a single review, potential users of the tasking facility are enabled to familiarise themselves with all the factors which may impinge upon the performance, reliability and correctness of their software. The book also provides a focus for any debate on modifications to the Ada language, or developments from it.
