Book Description

“Ruby on Rails™ 3 Tutorial: Learn Rails by Example by Michael Hartl has become a must read for developers learning how to build Rails apps.”
—Peter Cooper, Editor of Ruby Inside

Using Rails 3, developers can build web applications of exceptional elegance and power. Although its remarkable capabilities have made Ruby on Rails one of the world’s most popular web development frameworks, it can be challenging to learn and use. Ruby on Rails™ 3 Tutorial is the solution. Leading Rails developer Michael Hartl teaches Rails 3 by guiding you through the development of your own complete sample application using the latest techniques in Rails web development.

Drawing on his experience building RailsSpace, Insoshi, and other sophisticated Rails applications, Hartl illuminates all facets of design and implementation—including powerful new techniques that simplify and accelerate development.

You’ll find integrated tutorials not only for Rails, but also for the essential Ruby, HTML, CSS, JavaScript, and SQL skills you’ll need when developing web applications. Hartl explains how each new technique solves a real-world problem, and he demonstrates this with bite-sized code that’s simple enough to understand, yet novel enough to be useful. Whatever your previous web development experience, this book will guide you to true Rails mastery.

Book Description

Take advantage of Sinatra, the Ruby-based web application library and domain-specific language used by GitHub, LinkedIn, Engine Yard, and other prominent organizations. With this concise book, you will quickly gain working knowledge of Sinatra and its minimalist approach to building both standalone and modular web applications.

Sinatra serves as a lightweight wrapper around Rack middleware, with syntax that maps closely to functions exposed by HTTP verbs, which makes it ideal for web services and APIs. If you have experience building applications with Ruby, you’ll quickly learn language fundamentals and see under-the-hood techniques, with the help of several practical examples. Then you’ll get hands-on experience with Sinatra by building your own blog engine.

• Learn Sinatra’s core concepts, and get started by building a simple application
• Create views, manage sessions, and work with Sinatra route definitions
• Become familiar with the language’s internals, and take a closer look at Rack
• Use different subclass methods for building flexible and robust architectures
• Put Sinatra to work: build a blog that takes advantage of service hooks provided by the GitHub API

Book Description

The Ruby Programming Language is the authoritative guide to Ruby and provides comprehensive coverage of versions 1.8 and 1.9 of the language. It was written (and illustrated!) by an all-star team:

• David Flanagan, bestselling author of programming language “bibles” (including JavaScript: The Definitive Guide and Java in a Nutshell) and committer to the Ruby Subversion repository.
• Yukihiro “Matz” Matsumoto, creator, designer and lead developer of Ruby and author of Ruby in a Nutshell, which has been expanded and revised to become this book.
• why the lucky stiff, artist and Ruby programmer extraordinaire.

This book begins with a quick-start tutorial to the language, and then explains the language in detail from the bottom up: from lexical and syntactic structure to datatypes to expressions and statements and on through methods, blocks, lambdas, closures, classes and modules.

The book also includes a long and thorough introduction to the rich API of the Ruby platform, demonstrating — with heavily-commented example code — Ruby’s facilities for text processing, numeric manipulation, collections, input/output, networking, and concurrency. An entire chapter is devoted to Ruby’s metaprogramming capabilities.

The Ruby Programming Language documents the Ruby language definitively but without the formality of a language specification. It is written for experienced programmers who are new to Ruby, and for current Ruby programmers who want to challenge their understanding and increase their mastery of the language.

Ruby is famous for being easy to learn, but most users only scratch the surface of what it can do. While other books focus on Ruby’s trendier features, The Book of Ruby reveals the secret inner workings of one of the world’s most popular programming languages, teaching you to write clear, maintainable code.

You’ll start with the basics—types, data structures, and control flows—and progress to advanced features like blocks, mixins, metaclasses, and beyond. Rather than bog you down with a lot of theory, The Book of Ruby takes a hands-on approach and focuses on making you productive from day one. As you follow along, you’ll learn to:

• Leverage Ruby’s succinct and flexible syntax to maximize your productivity
• Balance Ruby’s functional, imperative, and object-oriented features
• Write self-modifying programs using dynamic programming techniques
• Create new fibers and threads to manage independent processes concurrently
• Catch and recover from execution errors with robust exception handling
• Develop powerful web applications with the Ruby on Rails framework

Each chapter includes a “Digging Deeper” section that shows you how Ruby works under the hood, so you’ll never be caught off guard by its deceptively simple scoping, multithreading features, or precedence rules.

Whether you’re new to programming or just new Ruby, The Book of Ruby is your guide to rapid, real-world software development with this unique and elegant language.

Book Description

It’s easy to write correct Ruby code, but to gain the fluency needed to write great Ruby code, you must go beyond syntax and absorb the “Ruby way” of thinking and problem solving. In Eloquent Ruby, Russ Olsen helps you write Ruby like true Rubyists do–so you can leverage its immense, surprising power.

Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the “Ah Ha!” moments when it suddenly becomes clear why Ruby works the way it does, and how you can take advantage of this language’s elegance and expressiveness.

Eloquent Ruby starts small, answering tactical questions focused on a single statement, method, test, or bug. You’ll learn how to write code that actually looks like Ruby (not Java or C#); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for.

Next, the book addresses bigger questions related to building methods and classes. You’ll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code–and why you’ll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages.

A part of the renowned Addison-Wesley Professional Ruby Series, Eloquent Ruby will help you “put on your Ruby-colored glasses” and get results that make you a true believer.

Review
“R>Eloquent Ruby is like programming in Ruby itself: fun, surprisingly deep, and you’ll find yourself wishing it was always done this way. Wherever you are in your Ruby experience from novice to Rails developer, this book is a must read.”–Ethan Roberts – Owner, Monkey Mind LLC

“Eloquent Ruby lives up to its name. It’s a smooth introduction to Ruby that’s both well organized and enjoyable to read, as it covers all the essential topics in the right order. This is the book I wish I’d learned Ruby from.”
–James Kebinger – Senior Software Engineer, PatientsLikeMe – www.monkeyatlarge.com

“Ruby’s syntactic and logical aesthetics represent the pinnacle for elegance and beauty in the ALGOL family of programming languages. Eloquent Ruby is the perfect book to highlight this masterful language and Russ’s blend of wit and wisdom is certain to entertain and inform.”
–Michael Fogus – Contributor to the Clojure programming language and author of The Joy of Clojure

Book Description

This book is directed at both industry practitioners and students interested in designing a pricing and risk management framework for financial derivatives using the Python programming language.

It is a practical book complete with working, tested code that guides the reader through the process of building a flexible, extensible pricing framework in Python. The pricing frameworks’ loosely coupled fundamental components have been designed to facilitate the quick development of new models. Concrete applications to real-world pricing problems are also provided.

Topics are introduced gradually, each building on the last. They include basic mathematical algorithms, common algorithms from numerical analysis, trade, market and event data model representations, lattice and simulation based pricing, and model development. The mathematics presented is kept simple and to the point.

The book also provides a host of information on practical technical topics such as C++/Python hybrid development (embedding and extending) and techniques for integrating Python based programs with Microsoft Excel.

The book is accompanied by a CD ROM containing a code library; and a companion website www.wiley.com/go/fletcher_python which will feature code-based updates relating to Python 3.0.

“Fletcher and Gardner have created a comprehensive resource that will be of interest not only to those working in the field of finance, but also to those using numerical methods in other fields such as engineering, physics, and actuarial mathematics. By showing how to combine the high-level elegance, accessibility, and flexibility of Python, with the low-level computational efficiency of C++, in the context of interesting financial modeling problems, they have provided an implementation template which will be useful to others seeking to jointly optimize the use of computational and human resources. They document all the necessary technical details required in order to make external numerical libraries available from within Python, and they contribute a useful library of their own, which will significantly reduce the start-up costs involved in building financial models. This book is a must read for all those with a need to apply numerical methods in the valuation of financial claims.”
–David Louton, Professor of Finance, Bryant University
