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. Download Now »

Book Description

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.

Book Description

“Hellmann’s writing has become an indispensable resource for me and many others as it fills a critical gap in Python Documentation with examples.”
— Jesse Noller, Python Core Developer and PSF Board Member

Master the Powerful Python Standard Library through Real Code Examples

The Python Standard Library contains hundreds of modules for interacting with the operating system, interpreter, and Internet—all extensively tested and ready to jump-start your application development. The Python Standard Library by Example introduces virtually every important area of the Python 2.7 library through concise, stand-alone source code/output examples, designed for easy learning and reuse.

Building on his popular Python Module of the Week blog series, author and Python expert Doug Hellmann focuses on “showing” not “telling.” He explains code behavior through downloadable examples that fully demonstrate each feature.

You’ll find practical code for working with text, data types, algorithms, math, file systems, networking, the Internet, XML, email, cryptography, concurrency, runtime and language services, and much more. Each section fully covers one module, and links to valuable additional resources, making this book an ideal tutorial and reference. Coverage includes

Book Description

Your work demands results, and you don’t have time for tedious, repetitive mathematical tasks. Sage is a free, open-source software package that automates symbolic and numerical calculations with the power of the Python programming language, so you can focus on the analytical and creative aspects of your work or studies.

Sage Beginner’s Guide shows you how to do calculations with Sage. Each concept is illustrated with a complete example that you can use as a starting point for your own work. You will learn how to use many of the functions that are built in to Sage, and how to use Python to write sophisticated programs that utilize the power of Sage.

This book starts by showing you how to download and install Sage, and introduces the command-line interface and the graphical notebook interface. It also includes an introduction to Python so you can start programming in Sage. Every major concept is illustrated with a practical example.

After learning the fundamentals of variables and functions in Sage, you will learn how to symbolically simplify expressions, solve equations, perform integrals and derivatives, and manipulate vectors and matrices. You will learn how Sage can produce numerous kinds of plots and graphics. The book will demonstrate numerical methods in Sage, and explain how to use object-oriented programming to improve your code.

Sage Beginner’s Guide will give you the tools you need to unlock the full potential of Sage for simplifying and automating mathematical computing. Download Now »
