The 'Crisis of Noosphere'
The ‘crisis of noosphere’ as a limiting factor to achieve the point of technological singularity Rafael Lahoz-Beltra Department of Applied Mathematics (Biomathematics). Faculty of Biological Sciences. Complutense University of Madrid. 28040 Madrid, Spain. [email protected] 1. Introduction One of the most significant developments in the history of human being is the invention of a way of keeping records of human knowledge, thoughts and ideas. The storage of knowledge is a sign of civilization, which has its origins in ancient visual languages e.g. in the cuneiform scripts and hieroglyphs until the achievement of phonetic languages with the invention of Gutenberg press. In 1926, the work of several thinkers such as Edouard Le Roy, Vladimir Ver- nadsky and Teilhard de Chardin led to the concept of noosphere, thus the idea that human cognition and knowledge transforms the biosphere coming to be something like the planet’s thinking layer. At present, is commonly accepted by some thinkers that the Internet is the medium that brings life to noosphere. Hereinafter, this essay will assume that the words Internet and noosphere refer to the same concept, analogy which will be justified later. 2 In 2005 Ray Kurzweil published the book The Singularity Is Near: When Humans Transcend Biology predicting an exponential increase of computers and also an exponential progress in different disciplines such as genetics, nanotechnology, robotics and artificial intelligence. The exponential evolution of these technologies is what is called Kurzweil’s “Law of Accelerating Returns”. The result of this rapid progress will lead to human beings what is known as tech- nological singularity. -

Mitigating Javascript's Overhead with Webassembly
Samuli Ylenius Mitigating JavaScript’s overhead with WebAssembly Faculty of Information Technology and Communication Sciences M. Sc. thesis March 2020 ABSTRACT Samuli Ylenius: Mitigating JavaScript’s overhead with WebAssembly M. Sc. thesis Tampere University Master’s Degree Programme in Software Development March 2020 The web and web development have evolved considerably during its short history. As a result, complex applications aren’t limited to desktop applications anymore, but many of them have found themselves in the web. While JavaScript can meet the requirements of most web applications, its performance has been deemed to be inconsistent in applications that require top performance. There have been multiple attempts to bring native speed to the web, and the most recent promising one has been the open standard, WebAssembly. In this thesis, the target was to examine WebAssembly, its design, features, background, relationship with JavaScript, and evaluate the current status of Web- Assembly, and its future. Furthermore, to evaluate the overhead differences between JavaScript and WebAssembly, a Game of Life sample application was implemented in three splits, fully in JavaScript, mix of JavaScript and WebAssembly, and fully in WebAssembly. This allowed to not only compare the performance differences between JavaScript and WebAssembly but also evaluate the performance differences between different implementation splits. Based on the results, WebAssembly came ahead of JavaScript especially in terms of pure execution times, although, similar benefits were gained from asm.js, a predecessor to WebAssembly. However, WebAssembly outperformed asm.js in size and load times. In addition, there was minimal additional benefit from doing a WebAssembly-only implementation, as just porting bottleneck functions from JavaScript to WebAssembly had similar performance benefits. -

Winner of the Wolfson History Prize 2017 Announced
PRESS RELEASE For immediate release Monday 15 May 2017 WINNER OF THE WOLFSON HISTORY PRIZE 2017 ANNOUNCED The winner of this year’s Wolfson History Prize, awarded for excellence in accessible and scholarly history, has been announced as Dr Christopher de Hamel for his book Meetings with Remarkable Manuscripts. De Hamel, who receives the £40,000 prize, is Fellow and former librarian of Corpus Christi College, Cambridge. He was one of six authors shortlisted for the Prize earlier this year. Awarded annually by the Wolfson Foundation for over forty years, the Wolfson History Prize has become synonymous with celebrating outstanding history. Established in 1972, it has awarded more than £1.1 million in recognition of the best historical writing being produced in the UK, reflecting qualities of both readability and excellence in writing and research. Sir David Cannadine, Chair of the Prize Judges, said: “Christopher de Hamel's outstanding and original book pushes the boundaries of what it is and what it means to write history. By framing each manuscript of which he writes as the story of his own personal encounter with it, he leads the reader on many unforgettable journeys of discovery and learning. Deeply imaginative, beautifully written, and unfailingly humane, Meetings with Remarkable Manuscripts distils a lifelong love of these astonishing historical treasures, which the author brings so vividly to life. It is a masterpiece.” About the Prize-winning book: Part travel book, part detective story, part conversation with the reader, Meetings with Remarkable Manuscripts conveys the fascination and excitement of encountering some of the greatest works of art in our culture which, in the originals, are to most people completely inaccessible. -

2012 Nw Boks n World History Harvard University Press New DENG XIAOPING AND THE TRANSFORMATION OF CHINA EZRA F. VOGEL ★ A New York Times Book Review Editors’ Choice ★ A Washington Post Best Book of the Year ★ An Economist Best Book of the Year ★ A Wall Street Journal Book of the Year No one in the twentieth century had a greater impact on world history than Deng Xiaoping. And no scholar is better qualified than Ezra Vogel to disentangle the contradictions embodied in the life and legacy of China’s boldest strategist—the pragmatic, disciplined force behind China’s radical economic, technological, and social transformation. “Vogel has gone to enormous lengths to document his subject…Vogel’s painstaking research provides plenty of fascinating detail…On the ways through which Deng set about the enormous task of rebuild - ing the gutted economy, shattered by decades of turmoil under Mao Zedong, Vogel is exhaustive.” —SIMON ELEGANT, TIME “Deng led a long and remarkable life, packed with drama and global significance, one that deserves to be dissected in detail…There’s no question that Vogel has gone farther than anyone else to date in telling Deng’s story. For that he is to be applauded; there is a whole hoard of valuable material here that we probably would not have gained otherwise.” —CHRISTIAN CARYL, FOREIGN POLICY “Ezra Vogel’s encyclopedic Deng Xiaoping and the Transformation of China is the most exhaustive English retelling of Deng’s life. Vogel…seems to have interviewed or found the memoirs of nearly every person who spoke with Deng, and has painstakingly re-created a detailed and intimate chronology of Deng’s roller-coaster career.” —JOSHUA KURLANTZICK, THE NATION “From arguably the most important scholar of East Asia, this is an important book on the force behind China’s transformation in the late twentieth century, whose full fruits are visible only today.
