Book Synopsis Modernizing Legacy Systems by : Robert C. Seacord
Download or read book Modernizing Legacy Systems written by Robert C. Seacord and published by Addison-Wesley Professional. This book was released on 2003 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most organizations rely on complex enterprise information systems (EISs) to codify their business practices and collect, process, and analyze business data. These EISs are large, heterogeneous, distributed, constantly evolving, dynamic, long-lived, and mission critical. In other words, they are a complicated system of systems. As features are added to an EIS, new technologies and components are selected and integrated. In many ways, these information systems are to an enterprise what a brain is to the higher species--a complex, poorly understood mass upon which the organism relies for its very existence. To optimize business value, these large, complex systems must be modernized--but where does one begin? This book uses an extensive real-world case study (based on the modernization of a thirty year old retail system) to show how modernizing legacy systems can deliver significant business value to any organization.

Book Synopsis A Legacy for Living Systems by : Jesper Hoffmeyer
Download or read book A Legacy for Living Systems written by Jesper Hoffmeyer and published by Springer Science & Business Media. This book was released on 2008-02-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gregory Bateson’s contribution to 20th century thinking has appealed to scholars from a wide range of fields dealing in one way or another with aspects of communication and epistemology. A number of his insights were taken up and developed further in anthropology, psychology, evolutionary biology and communication theory. But the large, trans-disciplinary synthesis that, in his own mind, was his major contribution to science received little attention from the mainstream scientific communities. This book represents a major attempt to revise this deficiency. Scholars from ecology, biochemistry, evolutionary biology, cognitive science, anthropology and philosophy discuss how Bateson's thinking might lead to a fruitful reframing of central problems in modern science. Most important perhaps, Bateson's bioanthropology is shown to play a key role in developing the set of ideas explored in the new field of biosemiotics. The idea that organismic life is indeed basically semiotic or communicative lies at the heart of the biosemiotic approach to the study of life. The only book of its kind, this volume provides a key resource for the quickly-growing substratum of scholars in the biosciences, philosophy and medicine who are seeking an elegant new approach to exploring highly complex systems.
Book Synopsis Beyond Legacy Code by : David Scott Bernstein
Download or read book Beyond Legacy Code written by David Scott Bernstein and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We're losing tens of billions of dollars a year on broken software, and great new ideas such as agile development and Scrum don't always pay off. But there's hope. The nine software development practices in Beyond Legacy Code are designed to solve the problems facing our industry. Discover why these practices work, not just how they work, and dramatically increase the quality and maintainability of any software project. These nine practices could save the software industry. Beyond Legacy Code is filled with practical, hands-on advice and a common-sense exploration of why technical practices such as refactoring and test-first development are critical to building maintainable software. Discover how to avoid the pitfalls teams encounter when adopting these practices, and how to dramatically reduce the risk associated with building software--realizing significant savings in both the short and long term. With a deeper understanding of the principles behind the practices, you'll build software that's easier and less costly to maintain and extend. By adopting these nine key technical practices, you'll learn to say what, why, and for whom before how; build in small batches; integrate continuously; collaborate; create CLEAN code; write the test first; specify behaviors with tests; implement the design last; and refactor legacy code. Software developers will find hands-on, pragmatic advice for writing higher quality, more maintainable, and bug-free code. Managers, customers, and product owners will gain deeper insight into vital processes. By moving beyond the old-fashioned procedural thinking of the Industrial Revolution, and working together to embrace standards and practices that will advance software development, we can turn the legacy code crisis into a true Information Revolution.

Book Synopsis The Legacy System by : Anthony Gibson
Download or read book The Legacy System written by Anthony Gibson and published by . This book was released on 2020-07-19 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Legacy horse racing system is a selection method devised by full time professional gambler and author Anthony Gibson. The book contains a detailed look at an area of horseracing that must be totally overlooked by the majority of punters otherwise the prices of the winners to date and the level stakes profits made would not be so great. Our source for the selections could be backed blindly and good profits achieved but adding elements of form and a common sense approach cuts down the number of runners to look at each day as possible bets, once a horse qualifies for selection they can be backed with great confidence either to win the race outright or to be placed. No other method I have ever looked at comes close to making the profits achieved in this book, this is a priceless piece of work and my final publication

Book excerpt: Legacy of Ash is an unmissable fantasy debut--an epic tale of intrigue and revolution, soldiers and assassins, ancient magic and the eternal clash of empires. A shadow has fallen over the Tressian Republic. Ruling families -- once protectors of justice and democracy -- now plot against one another with sharp words and sharper knives. Blinded by ambition, they remain heedless of the threat posed by the invading armies of the Hadari Empire. Yet as Tressia falls, heroes rise. Viktor Akadra is the Republic's champion. A warrior without equal, he hides a secret that would see him burned as a heretic. Josiri Trelanis Viktor's sworn enemy. A political prisoner, he dreams of reigniting his mother's failed rebellion. And yet Calenne Trelan, Josiri's sister, seeks only to break free of their tarnished legacy; to escape the expectation and prejudice that haunts the family name. As war spreads across the Republic, these three must set aside their differences in order to save their home. Yet decades of bad blood are not easily set aside. And victory -- if it comes at all -- will demand a darker price than any of them could have imagined.

Book Synopsis The Legacy of Division by : Ferenc Laczó
Download or read book The Legacy of Division written by Ferenc Laczó and published by Central European University Press. This book was released on 2020-10-15 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume examines the legacy of the East–West divide since the implosion of the communist regimes in Europe. The ideals of 1989 have largely been frustrated by the crises and turmoil of the past decade. The liberal consensus was first challenged as early as the mid-2000s. In Eastern Europe, grievances were directed against the prevailing narratives of transition and ever sharper ethnic-racial antipathies surfaced in opposition to a supposedly postnational and multicultural West. In Western Europe, voices regretting the European Union's supposedly careless and premature expansion eastward began to appear on both sides of the left–right and liberal–conservative divides. The possibility of convergence between Europe's two halves has been reconceived as a threat to the European project. In a series of original essays and conversations, thirty-three contributors from the fields of European and global history, politics and culture address questions fundamental to our understanding of Europe today: How have perceptions and misperceptions between the two halves of the continent changed over the last three decades? Can one speak of a new East–West split? If so, what characterizes it and why has it reemerged? The contributions demonstrate a great variety of approaches, perspectives, emphases, and arguments in addressing the daunting dilemma of Europe's assumed East–West divide.
