Fast-track your Web apps with Ruby on Rails
Ruby on Rails is a recent entry into the world of Web application development that is rapidly gaining mindshare, even while still in beta versions. Rails succeeds by automating the creation of the most common types of Web applications while not straightjacketing you if you want to add custom or atypical requirements. Moreover, compared to many Free Software libraries that perform individual aspects of a Web application, Rails contains a nicely integrated set of tools for all aspects. 		Articles 14 Jun 2005

Sockets programming in Ruby
This tutorial shows how to develop sockets-based networking applications using the Ruby language. You learn Ruby basics as well as the most important classes for sockets programming, and then look at a working chat application that illustrates these fundamentals. The tutorial finishes by exploring the higher-level classes that make it easy to build dynamic Web servers, mail servers and clients, and other application-layer protocols.

Test-first Ruby programming
This tutorial will build a simple Ruby application following Test First principles. It will start with an overview of the Test::Unit library that ships with Ruby then move on to writing tests from a specification and writing code to fulfill those test. It will touch on tools like ZenTest and unit_diff, and on the process of refactoring. The tutorial will be built around a single programming example. 		Tutorials 24 May 2005  
 
Charming Python: Hatch Python eggs with setuptools
David takes a look at the setuptools framework, a side project of the Python Enterprise Application Kit (PEAK). setuptools replaces the standard distutils library and adds versioned package and dependency management to Python. Perl users will be familiar with CPAN, and Ruby users with Gems; the tool ez_setup that bootstraps setuptools and the expanded easy_install that comes with it act in conjunction with "Cheeseshop" (the Python Package Index, also called "PyPI") to achieve the same thing. Moreover, setuptools lets you package your libraries in a single-file archive called an "egg," which is a lot like a Java JAR file, but for Python. 		Articles 24 Oct 2006  
 
Monitor home energy with AMEE
Electricity is invisible. To understand how people use it, you need to make it visible. This tutorial will show you how easy it is to build a Web-based energy monitoring system yourself, using a Current Cost real-time energy monitor and AMEE, a neutral Web-based API for energy data, combined with some XML, Ruby, Rails, and Ajax.

Developing software on an open source stack
Web developers are enjoying a renaissance. After spending much of the previous decade toiling on server-centric code, programmers are now putting code front-and-center, turning the Web browser into its own computing platform. Much of the renaissance must be attributed to ingenuity. The newest generation of tools and application frameworks automate and simplify the drudgery of building, deploying, and maintaining a Web site. There are also more tools than ever, and all the most innovative tools are open source. This tutorial provides an expansive survey of the free software available to developers to create and deploy Web applications. 		Tutorials 19 Aug 2008
