R is the world's most popular language for developing statistical software: Archaeologists use it to track the spread of ancient civilizations, drug companies use it to discover which medications are safe and effective, and actuaries use it to assess financial risks and keep economies running smoothly. The Art of R Programming takes you on a guided tour of software development with R, from basic types and data structures to advanced topics like closures, recursion, and anonymous functions. No statistical knowledge is required, and your programming skills can range from hobbyist to pro. Along the way, you'll learn about functional and object-oriented programming, running mathematical simulations, and rearranging complex data into simpler, more useful formats. You'll also learn to: * Create artful graphs to visualize complex data sets and functions * Write more efficient code using parallel R and vectorization * Interface R with C/C++ and Python for increased speed or functionality * Find new R packages for text analysis, image manipulation, and more * Squash annoying bugs with advanced debugging techniques Whether you're designing aircraft, forecasting the weather, or you just need to tame your data, The Art of R Programming is your guide to harnessing the power of statistical computing.

DevOps for Developers delivers a practical, thorough introduction to approaches, processes and tools to foster collaboration between software development and operations. Efforts of Agile software development often end at the transition phase from development to operations. This book covers the delivery of software, this means the last mile, with lean practices for shipping the software to production and making it available to the end users, together with the integration of operations with earlier project phases (elaboration, construction, transition).DevOps for Developers describes how to streamline the software delivery process and improve the cycle time (that is the time from inception to delivery). It will enable you to deliver software faster, in better quality and more aligned with individual requirements and basic conditions. And above all, work that is aligned with the DevOps approach makes even more fun!- Provides patterns and toolchains to integrate software development and operations.- Delivers an one-stop shop for kick-starting with DevOps.- Provides guidance how to streamline the software delivery process.

A vast amount of biological information about a wide range of species has become available in recent years as technological advances have significantly reduced the time it takes to sequence a genome or determine a novel protein structure. This text describes how bioinformatics can be used as a powerful set of tools for retrieving and analysing this biological data, and how bioinformatics can be applied to a wide range of disciplines such as molecular biology, medicine, biotechnology, forensic science and anthropology.Fully revised and updated, the fourth edition of Introduction to Bioinformatics contains two new chapters, with significantly increased coverage of metabolic pathways, and gene expression and regulation. This reflects the recent growth of interest in these areas in the field of bioinformatics.Written primarily for a biological audience without a detailed prior knowledge of programming, this book is the perfect introduction to the field of bioinformatics, providing friendly guidance and advice on how to use various methods and techniques. Furthermore, frequent examples, self-test questions, problems, and exercises are incorporated throughout the text to encourage self-directed learning.

Design, deploy, and maintain your own private or public Infrastructure as a Service (IaaS), using the open source OpenStack platform. In this practical guide, experienced developers and OpenStack contributors show you how to build clouds based on reference architectures, as well as how to perform daily administration tasks.Designed for horizontal scalability, OpenStack lets you build a cloud by integrating several technologies. This approach provides flexibility, but knowing which options to use can be bewildering. Once you complete this book, youll know the right questions to ask while you organize compute, storage, and networking resources. If you already know how to manage multiple Ubuntu machines and maintain MySQL, youre ready to:- Set up automated deployment and configuration- Design a single-node cloud controller- Use metrics to improve scalability- Explore compute nodes, network design, and storage- Install OpenStack packages- Use an example architecture to help simplify decision-making- Build a working environment to explore an IaaS cloud- Manage users, projects, and quotas- Tackle maintenance, debugging, and network troubleshooting- Monitor, log, backup, and restore

Ya ha pasado mucho tiempo desde la primera versión de ADO.NET Entity Framework, así como de la primera edición de esta obra, la cual supuso el primer libro editado sobre esta tecnología en el mundo. Esta nueva entrega, ademas de una revision profunda de los distintos conceptos explicados anteriormente, cubre tambien las nuevas funcionalidades de EF 4.0 y EF 4.1.Para apoyar a este libro y a los distintos recursos de ejemplos que lo acompañan, se ha incorporado una completa aplicacion de referencia en .NET 4.0 en la que se pueden ver muchas de las tecnicas y patrones explicados. Esta aplicacion -alojada en Codeplex- incorpora tambien elementos adicionales como WCF, WPF, Silverlight, MVC...La actual edicion de este libro se divide en seis capitulos principales mas una serie de apendices para ampliar algunos elementos.El texto comienza con un capitulo de introduccion tanto a la tecnologia EF 4.1 como a diferentes conceptos importantes que seran manejados a lo largo del resto de libro. Los siguientes capitulos introducen paulatinamente al lector en las distintas posibilidades que la tecnologia ofrece para consultar y actualizar los datos de un modelo conceptual. Todo ello se hace de una forma ordenada, tal y como se concibieron los distintos subsistemas que componen Entity Framework, y explicando las ventajas e inconvenientes de cada uno de ellos. Se desarrolla un ejercicio de aplicacion en el mundo real, apoyandose en la mencionada aplicacion de ejemplo que el usuario puede descargar y probar en Codeplex.Finalmente hay un capitulo entero de casi 100 paginas dedicado a la nueva caracteristica de EF 4.1: Code First.Dado que se profundiza conceptualmente en todos los temas, aparte de ser una herramienta fundamental de aprendizaje, este libro es tambien un manual de referencia que siempre querra tener a mano.

Se conoce como Big Data el tratamiento y análisis de grandes cantidades de datos, cuyo tamaño hace imposible manejarlos con las herramientas de bases de datos y analíticas convencionales. La proliferacion de paginas web, aplicaciones de imagen y video, redes sociales, dispositivos moviles, apps, sensores y otros dispositivos modernos capaces de generar enormes cantidades de datos han hecho necesario el desarrollo de herramientas de Big Data para su analisis. Hablamos de un entorno absolutamente relevante para muchos aspectos, desde el analisis de fenomenos naturales como el clima o de datos sismograficos, hasta entornos como salud, seguridad o, por supuesto, el ambito empresarial.En cuanto a las herramientas de Big Data se observa un desarrollo creciente. Oracle utiliza Exadata para estos propositos, SAS utiliza Visual Analytics y otras herramientas, Microsoft utiliza Windows Azure y en codigo abierto destaca Hadoop, un framework sumamente popular en este campo que permite a las aplicaciones trabajar con enormes repositorios de datos y miles de nodos inspirado en herramientas de Google como MapReduce o Google File System. IBM utiliza Power System e IBM SPSS Modeler.

Good game design happens when you view your game from as many perspectives as possible.Written by one of the world''s top game designers, The Art of Game Design presents 100+ sets of questions, or different lenses, for viewing a games design, encompassing diverse fields such as psychology, architecture, music, visual design, film, software engineering, theme park design, mathematics, puzzle design, and anthropology. This Second Edition of a Game Developer Front Line Award winner:- Describes the deepest and most fundamental principles of game design.- Demonstrates how tactics used in board, card, and athletic games also work in top-quality video games.- Contains valuable insight from Jesse Schell, the former chair of the International Game Developers Association and award-winning designer of Disney online games.The Art of Game Design, Second Edition gives readers useful perspectives on how to make better game designs faster. It provides practical instruction on creating world-class games that will be played again and again.
