That means you can't tap into the full power of Rails unless you master the Ruby language. ""Ruby for Rails,"" written by Ruby expert David Black (with a forward by David Heinemeier Hansson), helps Rails developers achieve Ruby mastery. Each chapter deepens your Ruby knowledge and shows you how it connects to Rails. You'll gain confidence working with objects and classes and learn how to leverage Ruby's elegant, expressive syntax for Rails application power. And you'll become a better Rails developer through a deep understanding of the design of Rails itself and how to take advantage of it.Newcomers to Ruby will find a Rails-oriented Ruby introduction that's easy to read and that includes dynamic programming techniques, an exploration of Ruby objects, classes, and data structures, and many neat examples of Ruby and Rails code in action. ""Ruby for Rails"": the Ruby guide for Rails developers!What's Inside Classes, modules, and objects Collection handling and filtering String and regular expression manipulation Exploration of the Rails source code Ruby dynamics Many more programming concepts and techniques!

    You will be able to look over the shoulder of major coding and design experts to see problems through their eyes.This is not simply another design patterns book, or another software engineering treatise on the right and wrong way to do things. The authors think aloud as they work through their project's architecture, the tradeoffs made in its construction, and when it was important to break rules. Beautiful Code is an opportunity for master coders to tell their story. All author royalties will be donated to Amnesty International.

    The text is divided into four parts: circuits, electronics, digital systems, and electromagnetics. Although it delves in depth into each of these topics, the text represents more than your basic survey of the basics of electrical engineering. A solid understanding of the fundamental principles on which modern electrical engineering is based is also provided. This edition includes a chapter on circuit analysis software SPICE, with a detailed discussion of the PC version known as PSPICE (from MicroSim Corp.). Numerous drill exercises have been added to this new edition, reinforcing ideas presented in the examples. There are over 1,000 end-of-chapter problems. This text is suitable for a variety of electrical engineering courses. It can be used as a text for an introduction to electrical engineering for both majors and non-majors or both, or can be split and the various chapters utilized for an introduction to circuits course, a first electronics course, or for a course on digital electronics and logic design.

    The result: more than thirty-five residences in fifteen countries -- and nearly every conceivable natural environment -- designed by a combination of star architects and heretofore unknown practitioners.Six different climactic zones are presented in The Green House -- waterfront, forest and mountain, tropical, desert, suburban, and urban; there is also a section on mobile dwellings. Each chapter features a series of homes that show the diversity and possibility of sustainable design. Projects are presented with large color images, plans, drawings, and an accompanying text that describes their green features and explains how they work with and in the environment.Architects included: Santiago Calatrava, Shigeru Ban, Miller/Hull, Rick Joy, Lake Flato, Kengo Kuma, Glenn Murcutt, Pugh & Scarpa, Werner Sobek, and many others.The Green House is not only a beautiful object in its own right, but is sure to be an indispensable reference for anyone building or interested in sustainable design -- and if you ask us, that should be everyone.

    Russ Olsen has done a great job of selecting classic patterns and augmenting these with newer patterns that have special relevance for Ruby. He clearly explains each idea, making a wealth of experience available to Ruby developers for their own daily work."--Steve Metsker, Managing Consultant with Dominion Digital, Inc."This book provides a great demonstration of the key 'Gang of Four' design patterns without resorting to overly technical explanations. Written in a precise, yet almost informal style, this book covers enough ground that even those without prior exposure to design patterns will soon feel confident applying them using Ruby. Olsen has done a great job to make a book about a classically 'dry' subject into such an engaging and even occasionally humorous read."--Peter Cooper"This book renewed my interest in understanding patterns after a decade of good intentions. Russ picked the most useful patterns for Ruby and introduced them in a straightforward and logical manner, going beyond the GoF's patterns. This book has improved my use of Ruby, and encouraged me to blow off the dust covering the GoF book."--Mike Stok" Design Patterns in Ruby is a great way for programmers from statically typed objectoriented languages to learn how design patterns appear in a more dynamic, flexible language like Ruby."--Rob Sanheim, Ruby Ninja, RelevanceMost design pattern books are based on C++ and Java. But Ruby is different--and the language's unique qualities make design patterns easier to implement and use. In this book, Russ Olsen demonstrates how to combine Ruby's power and elegance with patterns, and write more sophisticated, effective software with far fewer lines of code.After reviewing the history, concepts, and goals of design patterns, Olsen offers a quick tour of the Ruby language--enough to allow any experienced software developer to immediately utilize patterns with Ruby. The book especially calls attention to Ruby features that simplify the use of patterns, including dynamic typing, code closures, and "mixins" for easier code reuse.Fourteen of the classic "Gang of Four" patterns are considered from the Ruby point of view, explaining what problems each pattern solves, discussing whether traditional implementations make sense in the Ruby environment, and introducing Ruby-specific improvements. You'll discover opportunities to implement patterns in just one or two lines of code, instead of the endlessly repeated boilerplate that conventional languages often require. Design Patterns in Ruby also identifies innovative new patterns that have emerged from the Ruby community. These include ways to create custom objects with metaprogramming, as well as the ambitious Rails-based "Convention Over Configuration" pattern, designed to help integrate entire applications and frameworks.Engaging, practical, and accessible, Design Patterns in Ruby will help you build better software while making your Ruby programming experience more rewarding.

    Seeking to address the various challenges of off-camera lighting, professional photographers and advanced amateurs alike will find a range of confidence-building instruction, beginning with basic how’s and why’s of lighting for creative effect, the types of equipment available and instruction about their proper use, clear definitions of various technical concepts such as managing shutter speed and controlling flash exposure, using ambient light as well as natural sunlight during a shoot, and incorporating off-camera flash into a portrait session. Concluding this lesson plan is a look at five different real-life photo sessions, each employing a different flash technique. Here, photographers get a deeper understanding of each concept put into practice, marrying the elements of lighting with the natural elements presented by the shoot.
