Ruby In A Nutshell

Publisher	O'Reilly
Author(s)	Yukihiro Matsumoto
ISBN	0596002149
Release Date	03 November 2001

Ruby is an absolutely pure object-oriented scripting language written in C and designed with Perl and Python capabilities in mind. While its roots are in Japan, Ruby is slowly but surely gaining ground in the US. The goal of Yukihiro Matsumoto, creator of Ruby and author of this book, is to incorporate the strengths of languages like Perl, Python, Lisp and Smalltalk. Ruby is a genuine attempt to combine the best of everything in the scripting world. Since 1993, Ruby mailing lists have been established, Web pages have formed, and a community has grown around it. The language itself is very good at text processing and is notable for its broad object orientation. Ruby is portable and runs under GNU/Linux (and other Unices) as well as DOS, MS Windows and Mac. With Ruby in a Nutshell, Matsumoto offers a practical reference to the features of this new language including the command-line options, syntax, built-in variables, functions, and many commonly used classes and modules. This guide covers the current stable version of Ruby (1.6), yet is applicable to the development version 1.7 and the next planned stable version 1.8. You will find a thorough description of Ruby's language syntax, and a description of the core functionality built into the standard Ruby interpreter, which has more than 800 built-in methods in 42 classes and modules. Ruby finds its power through its built-in libraries, and this handy volume take you through the many useful libraries that come with the standard Ruby distribution--from network access via HTTP and CGI programming, to data persistence using the DBM library. This book concludes with coverage of the unique tools that come with Ruby, including the debugger, profiler, and irb (or interactive ruby.) Find out how Ruby combines the strengths of other languages, and why it has captured the interest of so many open source programmers. As part of the successful "in a nutshell" series of books from O'Reilly & Associates, Ruby in a Nutshell is for readers who want a single desktop reference for all their needs.

Practical Ruby for System Administration (Expert’s Voice in Open Source)

Ruby has set the world on fire, proving itself a serious challenger to Perl and Python in all spheres. In particular, more and more people are discovering that Ruby’s flexibility, superb feature set, and gentle learning curve make it a natural choice for system administration tasks, from the humblest server to the largest enterprise deployment.

Within the pages of Practical Ruby for System Administration, you’ll learn the Ruby way to construct files, tap into clouds of data, build domain-specific languages, perform network traffic analysis, and more.

Based on author André Ben Hamou’s own experiences working as a system administrator, this book will help you pick up practical tips on Ruby coding style, learn how to analyze and improve script performance, and make use of no-nonsense advice on scripting workflow, including testing and documentation.

Above all, you’ll come to appreciate the sheer power of Ruby and the hundreds of benefits it offers for system administration.
This book places equal emphasis on fundamental Ruby concepts as well as practical how-tos.
It uses examples from other languages to ease the transition to Ruby.
The book is concise, entertaining, and informative–unlike many books aimed at system administrators, which can be overly long and stodgy.

Book Description: )
Are you a tester who spends more time manually creating complex test data than using it? A business analyst who seemingly went to college all those years so you can spend your days copying data from reports into spreadsheets? A programmer who can't finish each day's task without having to scan through version control system output, looking for the file you want?
If so, you're wasting that computer on your desk. Offload the drudgery to where it belongs, and free yourself to do what you should be doing: thinking. All you need is a scripting language (free!), this book (cheap!), and the dedication to work through the examples and exercises.
Everyday Scripting with Ruby is divided into four parts. In the first, you'll learn the basics of the Ruby scripting language. In the second, you'll see how to create scripts in a steady, controlled way using test-driven design. The third part is about finding, understanding, and using the work of others--and about preparing your scripts for others to use. The fourth part, more advanced, is about saving even more time by using application frameworks.
