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.

Este libro corresponde a un curso de introducción a la programación. Se desarrolla en el contexto del lenguaje C++, pero en lugar de guiarse por el lenguaje, se desarrolla estudiando los fundamentos de la programacion estructurada. Para ello, se evitan los aspectos de mas bajo nivel, creando soluciones basadas en los tipos basicos de la STL.Este planteamiento novedoso nos permite presentar un curso basado en un lenguaje complejo como es C++, pero que queda al alcance de un estudiante sin ningun conocimiento de programacion.Los contenidos abarcan temas que van desde los tipos simples y las sentencias basicas del lenguaje hasta la creacion de proyectos de multiples archivos, incluyendo tipos compuestos y gestion de E/S con archivos de texto.Como resultado, el lector tendra una idea clara de cuales son los fundamentos de la programacion, pero tambien tendra una base solida para poder abordar cursos mas avanzados, ya sea en este lenguaje o en otro.Este enfoque docente permite usar este libro en muchos contextos, no solo en las titulaciones de ingenieria informatica, sino en otras ingenierias, en estudios medios e incluso de forma autodidacta.

Swift 2 for Absolute Beginners is perfect for those with no programming background, those with some programming experience but no object-oriented experience, or those that have a great idea for an app but havent programmed since school, and it is now updated for Swift 2.Gary Bennett and Brad Lees are full-time professional iOS developers and have developed a broad spectrum of apps for Fortune 500 companies. The authors have taken their combined 12 years of writing apps, teaching online iOS courses, the experience from their first three iOS books, along with their online instruction and free online forum at XcelMe.com to create an excellent training book.Many people have a difficult time believing they can learn to write iOS apps or just staying motivated through learning the process. This book, along with the free, live online training sessions, helps students stay motivated and overcome obstacles while they learn to be great iOS developers.- Using Swift Playgrounds to learn iOS development quickly.- What is Object Oriented Programming.- What are Swift classes, properties, and functions.- Proper user interface and user experience design.- Swift data types: integers, floats, strings, booleans.- How to use Swift data collections: arrays and dictionaries.- Boolean logic, comparing data, and flow control.- Writing iPhone and Watch apps from scratch.- Introduction to HealthKit.

Sams Teach Yourself Visual Basic in 24 Hours is perfect for students new to programming, as well as those moving from another language to Visual Basic. It focuses on programming principles. Throughout this book, students will learn to build an application a Picture Viewer, complete with file browsing, printing, basic graphics drawing, menus, toolbars, and more.As mentioned above, many of the changes wont directly affect the beginner-level material presented in this book. There are changes to the design environment that will be integrated into the existing material appropriately. The Barnes and Noble edition will include two bonus chapters. The author will swap the bonus chapter on printing with the chapter on controlling other applications using Automation. Other changes worth noting:Updated screenshotsRefined example material (for instance, the author plans to add a zoom feature to the Picture Viewer project in the chapter on Graphics).Change to current hour 24 (a 10,000 foot overview) to an appendix, and create a new chapter on sending emails. The new TOC reflects this recommendation. Note that the old hour 23 (deploying solutions) was made hour 24, and the new email chapter is hour 23.If the sales reps ask, coverage of the new 2015 features that will be woven into the appropriate chapters are outlined below:Code Editor UI and Editing (Roslyn) Light Bulbs are the new home for all quick actions you take in the Visual Studio Editor, including fixes to common code issues and refactoring code. There are two new core refactoring operations: Inline temporary variable and Introduce local. Refactoring support for Visual Basic has been added for the first time, and has also been moved to the Light Bulb. Renaming has also been improved; now it highlights all the instances of the identifier you want to rename, letting you type the new name to all instances at once directly in the editor. The expression evaluator for C# and Visual Basic has been rewritten. Nameof() provides a refactoring-safe way of getting the name of e.g. a parameter, member or type as a string. Using null-conditional operators you can get a built-in null check while accessing and invoking members and indexers. String interpolation: String interpolation provides a concise way of describing string templates that insert expressions into format strings (C# only at Preview, both VB and C# at RTM). View Call Hierarchy. Find all References. Multi-line strings. References Node is now in solution explorer. Custom Windows Layouts.Debugging Conditional statements break only when conditions you specify are met. Think of this as adding an if statement to your code and placing the breakpoint inside the if statement so it is only hit when the conditions you entered are true. Hit counts break only after the breakpoint has been hit a certain number of times. These are useful in situations where code is called multiple times, and you either know the exactly when it is failing, or have a general idea that it fails after at least a certain number of times. Filters break when the breakpoint is hit on a specific thread, process, or machine and are useful for debugging code running in parallel. Tracepoints print a message to the output window and are capable of automatically resuming execution. These are useful for doing temporary logging when you need to trace something and dont want to have to break and manually track values.

Learn the Root Causes of Software Vulnerabilities and How to Avoid Them.Commonly exploited software vulnerabilities are usually caused by avoidable software defects. Having analyzed tens of thousands of vulnerability reports since 1988, CERT has determined that a relatively small number of root causes account for most of the vulnerabilities.Secure Coding in C and C++, Second Edition, identifies and explains these root causes and shows the steps that can be taken to prevent exploitation. Moreover, this book encourages programmers to adopt security best practices and to develop a security mindset that can help protect software from tomorrows attacks, not just todays. Drawing on the CERTs reports and conclusions, Robert C. Seacord systematically identifies the program errors most likely to lead to security breaches, shows how they can be exploited, reviews the potential consequences, and presents secure alternatives.Coverage includes technical detail on how to- Improve the overall security of any C or C++ application.- Thwart buffer overflows, stack-smashing, and return-oriented programming attacks that exploit insecure string manipulation logic.- Avoid vulnerabilities and security flaws resulting from the incorrect use of dynamic memory management functions.- Eliminate integer-related problems resulting from signed integer overflows, unsigned integer wrapping, and truncation errors.- Perform secure I/O, avoiding file system vulnerabilities.- Correctly use formatted output functions without introducing format-string vulnerabilities.- Avoid race conditions and other exploitable vulnerabilities while developing concurrent code.Secure Coding in C and C++, Second Edition, presents hundreds of examples of secure code, insecure code, and exploits, implemented for Windows and Linux. If youre responsible for creating secure C or C++ softwareor for keeping it safeno other book offers you this much detailed, expert assistance.
