TL;DR: This book presents the nature and characteristics of modern-day operating systems clearly and completely, and serves as both a basic reference and an up-to-date survey of the state of the art.
Abstract: Serving as both a basic reference and an up-to-date survey of the state of the art, this book covers the concepts, structure, and mechanisms of operating systems. Stallings presents the nature and characteristics of modern-day operating systems clearly and completely. Updated treatment of Windows as a case study to cover Windows Vista. Online animations with references incorporated throughout. A new chapter on Embedded Operating Systems. Part Six (Distributed Systems and Security) moved online, reducing the cost and size of the book without loss of content. Expanded coverage of security. New figures added, with many existing figures updated to enhance clarity. A useful reference for programmers, systems engineers, network designers and others involved in the design of computer products, information system and computer system personnel.

TL;DR: In this article, a comprehensive introduction to parallel computing is provided, discussing theoretical issues such as the fundamentals of concurrent processes, models of parallel and distributed computing, and metrics for evaluating and comparing parallel algorithms, as well as practical issues, including methods of designing and implementing shared-and distributed-memory programs, and standards for parallel program implementation.
Abstract: The constantly increasing demand for more computing power can seem impossible to keep up with. However, multicore processors capable of performing computations in parallel allow computers to tackle ever larger problems in a wide variety of applications. This book provides a comprehensive introduction to parallel computing, discussing theoretical issues such as the fundamentals of concurrent processes, models of parallel and distributed computing, and metrics for evaluating and comparing parallel algorithms, as well as practical issues, including methods of designing and implementing shared- and distributed-memory programs, and standards for parallel program implementation, in particular MPI and OpenMP interfaces. Each chapter presents the basics in one place followed by advanced topics, allowing novices and experienced practitioners to quickly find what they need. A glossary and more than 80 exercises with selected solutions aid comprehension. The book is recommended as a text for advanced undergraduate or graduate students and as a reference for practitioners.

TL;DR: The authors argue that in order to understand the successes of software platforms, the authors must first understand their role as a technological meeting ground where application developers and end users converge, and recommend firms that recognize the transformative power unleashed by this new revolution.
Abstract: Winner of the Business, Management & Accounting category in the 2006 Professional/Scholarly Publishing Annual Awards Competition presented by the Association of American Publishers, Inc. Software platforms are the invisible engines that have created, touched, or transformed nearly every major industry for the past quarter century. They power everything from mobile phones and automobile navigation systems to search engines and web portals. They have been the source of enormous value to consumers and helped some entrepreneurs build great fortunes. And they are likely to drive change that will dwarf the business and technology revolution we have seen to this point. Invisible Engines examines the business dynamics and strategies used by firms that recognize the transformative power unleashed by this new revolutiona revolution that will change both new and old industries. The authors argue that in order to understand the successes of software platforms, we must first understand their role as a technological meeting ground where application developers and end users converge. Apple, Microsoft, and Google, for example, charge developers little or nothing for using their platforms and make most of their money from end users; Sony PlayStation and other game consoles, by contrast, subsidize users and make more money from developers, who pay royalties for access to the code they need to write games. More applications attract more users, and more users attract more applications. And more applications and more users lead to more profits. Invisible Engines explores this story through the lens of the companies that have mastered this platform-balancing act. It offers detailed studies of the personal computer, video game console, personal digital assistant, smart mobile phone, and digital media software platform industries, focusing on the business decisions made by industry players to drive profits and stay a step ahead of the competition. Shorter discussions of Internet-based software platforms provide an important glimpse into a future in which the way we buy, pay, watch, listen, learn, and communicate will change forever.

TL;DR: This paper reviews the computational architecture of HAMMER (Hierarchical Attentive Multiple Models for Execution and Recognition), where the motor control systems of a robot are organised in a hierarchical, distributed manner, and demonstrates that such an arrangement can provide a principled method for the top-down control of attention during action perception.

TL;DR: Differences in ribosomes across species reveal that rRNA expansion segments have been added to rRNAs without perturbing the preexisting core, and provides insight to the structure of pre-last universal common ancestor r RNAs and the subsequent expansions that shaped the peptidyl transferase center and the conserved core.
Abstract: The origins and evolution of the ribosome, 3–4 billion years ago, remain imprinted in the biochemistry of extant life and in the structure of the ribosome. Processes of ribosomal RNA (rRNA) expansion can be “observed” by comparing 3D rRNA structures of bacteria (small), yeast (medium), and metazoans (large). rRNA size correlates well with species complexity. Differences in ribosomes across species reveal that rRNA expansion segments have been added to rRNAs without perturbing the preexisting core. Here we show that rRNA growth occurs by a limited number of processes that include inserting a branch helix onto a preexisting trunk helix and elongation of a helix. rRNA expansions can leave distinctive atomic resolution fingerprints, which we call “insertion fingerprints.” Observation of insertion fingerprints in the ribosomal common core allows identification of probable ancestral expansion segments. Conceptually reversing these expansions allows extrapolation backward in time to generate models of primordial ribosomes. The approach presented here provides insight to the structure of pre-last universal common ancestor rRNAs and the subsequent expansions that shaped the peptidyl transferase center and the conserved core. We infer distinct phases of ribosomal evolution through which ribosomal particles evolve, acquiring coding and translocation, and extending and elaborating the exit tunnel.
