One of the most promising innovations in testing in the past year is the introduction and rapid growth of RSpec, a behavior-driven testing tool. Learn how RSpec can change the way you think about testing.http://www.developerhell.com/out/Registration_form_with_Merb_and_Datamapperhttp://www.developerhell.com/out/Registration_form_with_Merb_and_DatamapperHow to setup a semi-advanced registration form with Merb and Datamapper with validators and stuff.http://www.developerhell.com/out/Rails_Messaging_Tutorialhttp://www.developerhell.com/out/Rails_Messaging_TutorialThis guide aims to be a simple, logical tutorial showing how to develop a simple Rails messaging system with all of the trimmings with Ruby on Rails (v2.0.2). This tutorial is intended for beginner to intermediate Rails users. If you've never used Rails before, I suggest you check out any of the excellent introductions out there.http://www.developerhell.com/out/Merb_and_Datamapper_on_Ubuntu_with_XAMPPhttp://www.developerhell.com/out/Merb_and_Datamapper_on_Ubuntu_with_XAMPPBasic setup tutorial to get you started with Merb and Datamapper.http://www.developerhell.com/out/Adding_Type_Checking_to_Rubyhttp://www.developerhell.com/out/Adding_Type_Checking_to_RubyWhat’s the first thing you think of when you consider the Ruby Language? Dynamic types, right? Ruby is famous (infamous?) for its extremely flexible type system, and as a so-called “scripting language”, the core of this mechanism is a lack of type checking. This feature allows for some very concise expressions and a great deal of flexibility, but sometimes makes your code quite a bit harder to understand.http://www.developerhell.com/out/Ruby_Spin_up_Where_Did_That_Method_Come_Fromhttp://www.developerhell.com/out/Ruby_Spin_up_Where_Did_That_Method_Come_FromA tutorial that gives a nice background on some object-oriented thinking in Ruby, including classes, superclasses, modules, and singleton methods. It's a straightforward tutorial aimed at those who have gotten their feet wet in Ruby, but not the object-oriented aspects of Ruby.http://www.developerhell.com/out/Ruby_1_9_When_Will_It_be_Production_Readyhttp://www.developerhell.com/out/Ruby_1_9_When_Will_It_be_Production_ReadyRuby 1.9 was released on Christmas Day of 2007 as version 1.9.0, after undergoing a year or so as an experimental testbed for changes to the Ruby language and core class library.http://www.developerhell.com/out/Sorting_Data_with_List_and_Table_Widgets_pdfhttp://www.developerhell.com/out/Sorting_Data_with_List_and_Table_Widgets_pdfThe simple widgets that we learned about in the previous chapter primarily deal with a single value (if they have any real "value" associated with them at all). FXRuby also provides a number of more complicated widgets for dealing with collections of values.http://www.developerhell.com/out/Ruby_blocks_gotchashttp://www.developerhell.com/out/Ruby_blocks_gotchasThere's this thing they say about Ruby - everything is an object. It's true, with very few exceptions, one of them being the block. Well guess what, this little gem of an inconsistency came back to bite me when I was trying to do something involving dynamic redefinition of methods.http://www.developerhell.com/out/Configuring_ActionMailerhttp://www.developerhell.com/out/Configuring_ActionMailerConfiguring ActionMailer for the first time can be a little bit troublesome. You have to worry about the server, port, domain, authentication, address to send from and whether you're configuring smtp or sendmail. You have to set things up for both your production and development servers, and you have to make sure that everything's kosher so that your messages won't get knocked down by spam filters.http://www.developerhell.com/out/Rails_2_0_It_s_donehttp://www.developerhell.com/out/Rails_2_0_It_s_doneRails 2.0 is finally finished after about a year in the making. This is a fantastic release that's absolutely stuffed with great new features, loads of fixes, and an incredible amount of polish. We've even taken a fair bit of cruft out to make the whole package more coherent and lean.http://www.developerhell.com/out/Ruby_on_Rails_on_Oracle_A_Simple_Tutorialhttp://www.developerhell.com/out/Ruby_on_Rails_on_Oracle_A_Simple_TutorialThis article is not intended to be a booster piece for Rails nor is it an expose. It's simply an introduction to the technology. It contains both praise and criticism. At times the criticism might appear a bit heavy handed (especially to Rails enthusiasts), but don't be fooled. Using any Web application framework is going to be tricky, whether it's J2EE, ASP.NET, or PHP. In the long run, you can be a lot more productive with Rails than you can be with many other Web application development platforms, but it takes time to learn the ropes.http://www.developerhell.com/out/10_Reasons_to_Learn_Rubyhttp://www.developerhell.com/out/10_Reasons_to_Learn_RubyThere are plenty4 of introductions, tutorials, articles and essays of different sorts which aim to guide the novice and advise the guru on how to get the most out of Ruby. This article, however, is not one of them.http://www.developerhell.com/out/AIM_Bot_in_Rubyhttp://www.developerhell.com/out/AIM_Bot_in_RubyWas searching for how to do an AIM Bot in Ruby tonight. Screwed around a bit with ROscar and Raimbot. But the light at the end of the tunnel is here: Net::TOC.http://www.developerhell.com/out/Using_Ruby_on_Rails_for_Web_Development_on_Mac_OS_Xhttp://www.developerhell.com/out/Using_Ruby_on_Rails_for_Web_Development_on_Mac_OS_XIt should come as no surprise that Mac OS X is a favored platform for Rails development. Rails and its supporting cast of web servers and databases thrive on the rich Mac OS X environment. A popular text editor used by many Rails programmers is TextMate, a Cocoa application. And all members of the Rails core development team work with Macs.http://www.developerhell.com/out/Sinatra_similar_to_web_py_but_in_rubyhttp://www.developerhell.com/out/Sinatra_similar_to_web_py_but_in_rubyWeb development framework similar to web.pyhttp://www.developerhell.com/out/Simple_WxRuby_applicationhttp://www.developerhell.com/out/Simple_WxRuby_applicationThis is a real world example that demonstrates a how a small application that is using WxRuby and WxSugar for the display could work.http://www.developerhell.com/out/Using_script_aculo_us_in_Ruby_on_Railshttp://www.developerhell.com/out/Using_script_aculo_us_in_Ruby_on_RailsScript.aculo.us is indeed spectaculous. By writing a few lines of ROR code, you could create UI effects that reqiured great manipulation in javascript using DOM.http://www.developerhell.com/out/Object_relation_mapping_put_on_railshttp://www.developerhell.com/out/Object_relation_mapping_put_on_railsActive Record connects business objects and database tables to create a persistable domain model where logic and data are presented in one wrapping. It's an implementation of the object-relational mapping (ORM) pattern by the same name as described by Martin Fowlerhttp://www.developerhell.com/out/How_the_Ruby_heap_is_implementedhttp://www.developerhell.com/out/How_the_Ruby_heap_is_implementedIt's been a while since I've worked on Ruby's garbage collector, and my memory about it is getting dusty. At the time, I noticed that there's very little documentation about the Ruby interpreter implementation. There are little pieces of comments here and there, and a few slides and emails all over the Internet, but nothing comprehensive
