- Build a Web spider on Linux by M. Tim Jones - [Clicks: 9]
Web spiders are software agents that traverse the Internet gathering, filtering, and potentially aggregating information for a user. Using common scripting languages and their collection of Web modules, you can easily develop Web spiders. This article shows you how to build spiders and scrapers for Linux to crawl a Web site and gather information, stock data, in this case.

Statically typed languages, such as the Java language and C, bind a method call to their implementation at compile time. This strategy lets these languages perform a wide variety of syntax and type checks, giving them more stability -- and often better performance -- than dynamically typed languages that have no such compile-time checks. But static typing comes with a serious limitation: early binding. Some dynamic languages -- such as Ruby, Smalltalk, and Self -- allow delayed binding, which enables another level of programming features.

It's fairly easy to prevent errors in code from occurring and reoccurring; unit tests are an effective strategy to prevent regressions. What about the example code in your documentation? Errors there can frustrate and thwart readers and learners. Fortunately, it's possible to test your documentation almost as effectively. Leonard Richardson, co-author of the Ruby Cookbook, demonstrates how he kept his code examples correct.

Dynamic languages are the up-and-coming competitors to Java. Expanding their scope beyond glue code and Web GUIs into the heavy-duty challenges once faced only with a compiler, languages such as Python, PHP, Groovy, and Ruby have rapidly gained popularity among programmers. Ruby in particular has attracted attention, with a big boost from the Ruby on Rails Web framework. Java programmers who appreciate the value of Ruby still need a way to get it to play nicely with the huge installed base of Java software. The JRuby interpreter provides the solution. Like the Jython interpreter and the Python language, JRuby executes Ruby code and allows Ruby objects to call Java code, and vice versa. In this article, Joshua Fox introduces Java programmers to Ruby, focusing on the similarities, differences, and connectivity between the two languages.

The Java community has used JavaServer Pages (JSP) technology through most of the last decade, but signs of rust are starting to show. Longstanding conventions inhibit Java programmers from using Java code within Web pages now, and extending even simple components is a chore. Frameworks that take Java Web development beyond JSP programming have emerged, but they fall short of dynamic languages' capabilities. This article shows you Ruby's Web page development strategy and touches on Seaside's radical approach.

There's a whole world of language features that we sometimes miss out on as Rubyists, such as pattern matching, S-expressions, and external domain-specific languages. But the good news is that we can have them, too, as long as we're not afraid to steal a few things first.

http://www.devx.com/enterprise/Article/30917 - Mar, 2006 - Creating DSLs with Ruby by Jim Freeze - [Clicks: 11]
Broadly speaking, there are two ways to create a DSL. One is to invent a syntax from scratch, and build an interpreter or compiler. The other is to tailor an existing general-purpose language by adding or changing methods, operators, and default actions. This article explores using the latter method to build a DSL on top of Ruby.

- Everyday Scripting with Ruby: For Technologists, Testers, and You
by Brian Marick - [Clicks: 23]
Are you a tester who doesn't get enough time to actually test? Do you spend your time configuring machines, wrestling with bug-reporting systems, manually creating complex test data, and repeating the same manual tests you've run a hundred times before? 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.
Pragmatic Bookshelf, Paperback - Dec, 2006 - Ruby Way, Second Edition, The: Solutions and Techniques in Ruby Programming, 2nd Edition
by Hal Fulton - [Clicks: 16]

Its popularity has grown tremendously in the five years since the first edition of this book. The Ruby Way takes a “how-to” approach to Ruby programming with the bulk of the material consisting of more than 400 examples arranged by topic. Each example answers the question “How do I do this in Ruby?” Working along with the author, you are presented with the task description and a discussion of the technical constraints. This is followed by a step-by-step presentation of one good solution. Along the way, the author provides detailed commentary and explanations to aid your understanding.

O'Reilly Media, Inc., Paperback - Sep, 2006 - From Java to Ruby. Things Every Manager Should Know
by Bruce Tate - [Clicks: 10]
If you're trying to adopt Ruby in your organization and need some help, this is the book for you. Based on a decision tree (a concept familiar to managers and executives) Java to Ruby stays above the low-level technical debate to examine the real benefits and risks to adoption. Java to Ruby is packed with interviews of Ruby customers and developers, so you can see what types of projects are likely to succeed, and which ones are likely to fail. Ruby and Rails may be the answer, but first, you need to be sure you're asking the right question. By addressing risk and fitness of purpose, Java to Ruby makes sure you're asking the right questions first. Because technology adoption is only the beginning, Java to Ruby walks you through the whole lifecycle of prototype, ramp up, and production and deployment.
