Hoy en día, los ingenieros de software necesitan saber no solo cómo programar eficazmente, sino también cómo desarrollar prácticas de ingeniería para que la base de código sea sostenible y funcione bien. Este libro hace hincapie en esta diferencia, entre la programacion y la ingenieria de software. ¿Como pueden gestionar los ingenieros de software una base de codigo viva que evoluciona y responde a requisitos y demandas cambiantes a lo largo de su vida?A partir de su experiencia en Google, los ingenieros de software Titus Winters y Hyrum Wright, junto con el escritor tecnico Tom Manshreck, presentan una mirada sincera y perspicaz sobre como construyen y mantienen el software algunos de los principales profesionales del mundo.Este libro trata de la cultura, los procesos y las herramientas de ingenieria exclusivas de Google, y de como estos aspectos contribuyen a la eficacia de una organizacion de ingenieria de software. Explorara tres principios fundamentales que las organizaciones de software deben tener en cuenta a la hora de diseñar, establecer la arquitectura, escribir y mantener el codigo: Como afecta el tiempo a la sostenibilidad del software y como hacer que su codigo resista el paso del tiempo. Como afecta la escala a la viabilidad de las practicas de software dentro de una organizacion de ingenieria de software. Que contrapartidas debe tener en cuenta el ingeniero de software al evaluar las decisiones de diseño y los desarrollos.

With a simple Pro Mini board and a few other components, projects that 20 or 30 years ago were unthinkable (or would have cost a small fortune) are realized easily and affordably in this book: From simple LED effects to a full battery charging and testing station that will put a rechargeable through its paces, theres something for everyone. All the projects are based on the ATmega328 microcontroller, which offers endless measuring, switching, and control options with its 20 input and output lines. For example, with a 7-segment display and a few resistors, you can build a voltmeter or an NTC-based thermometer. The Arduino platform offers the perfect development environment for programming this range of boards. Besides these very practical projects, the book also provides the necessary knowledge for you to create projects based on your own ideas. How to measure, and what? Which transistor is suitable for switching a certain load? When is it better to use an IC? How do you switch mains voltage? Even LilyPad-based battery-operated projects are discussed in detail, as well as many different motors, from simple DC motors to stepper motors. Sensors are another exciting topic: For example, a simple infrared receiver that can give disused remote controls a new lease on life controlling your home, and a tiny component that can actually measure the difference in air pressure between floor and table height!

How is the Web transforming the professional practice of archaeology? And as archaeologists accustomed to dealing with "deep time," how can we best understand the possibilities and limitations of the Web in meeting the specialized needs of professionals in this field? These are among the many questions posed and addressed in Archaeology 2.0: New Approaches to Communication and Collaboration, edited by Eric Kansa, Sarah Whitcher Kansa, and Ethan Watrall. With contributions from a range of experts in archaeology and technology, this volume is organized around four key topics that illuminate how the revolution in communications technology reverberates across the discipline: approaches to information retrieval and information access; practical and theoretical concerns inherent in design choices for archaeologys computing infrastructure; collaboration through the development of new technologies that connect field-based researchers and specialists within an international archaeological community and scholarly communications issues, with an emphasis on concerns over sustainability and preservation imperatives. This book not only describes practices that attempt to mitigate some of the problems associated with the Web, such as information overload and disinformation, it also presents compelling case studies of actual digital projects--many of which are rich in structured data and multimedia content or focused on generating content from the field "in real time," and all of which demonstrate how the Web can and is being used to transform archaeological communications into forms that are more open, inclusive, and participatory. Above all, this volume aims to share these experiences to provide useful guidance for other researchers interested in applying technology to archaeology.
