This testing collects the application performance and stability data in different scenarios, and is used for analyzing this data in order to scale the application for better performance.http://www.developerhell.com/out/Scraping_and_Converting_Data_with_Hpricot_and_JSON_in_Rubyhttp://www.developerhell.com/out/Scraping_and_Converting_Data_with_Hpricot_and_JSON_in_RubyWe're retrieving information from a HTML document with Hpricot, no regular expressions needed.http://www.developerhell.com/out/Autocomplete_in_WxRuby_s_Scintilla3691http://www.developerhell.com/out/Autocomplete_in_WxRuby_s_Scintilla3691How to accomplish autocompletion when you write your own editor.http://www.developerhell.com/out/AUI_in_WxRubyhttp://www.developerhell.com/out/AUI_in_WxRubyAdvanced User Interface to create all the coolness you need in your desktop application.http://www.developerhell.com/out/The_basics_of_how_to_work_the_Scintilla_component_in_WxRubyhttp://www.developerhell.com/out/The_basics_of_how_to_work_the_Scintilla_component_in_WxRubyThe basics of how to work the Scintilla component in WxRuby.http://www.developerhell.com/out/Project_browser_in_WxRubyhttp://www.developerhell.com/out/Project_browser_in_WxRubyAdvanced TreeCtrl tutorialhttp://www.developerhell.com/out/CSS_Star_Rating_Systemhttp://www.developerhell.com/out/CSS_Star_Rating_SystemRecently I had to create a Star Rating system for a client so I thought I'd share with you the techniques I used to accomplish this. If you are not familiar with a Star Rating System, it's simply a method of voting using (usually) 5 stars in a row, which will change colour as you hover over them indicating the level at which to rate something.http://www.developerhell.com/out/More_Scintilla_in_WxRubyhttp://www.developerhell.com/out/More_Scintilla_in_WxRubyA discussion on custom key commands and custom behavior.http://www.developerhell.com/out/A_Lightweight_Approach_to_Aspect_Oriented_Programming_in_Pythonhttp://www.developerhell.com/out/A_Lightweight_Approach_to_Aspect_Oriented_Programming_in_Pythonaspects.py library provides means to intercept function calls. Functions and methods (also in Python standard library and third party code) can be wrapped so that when they are called, the wrap is invoked first. Depending on the wrap, the execution of the original function can be omitted, or the function can be called arbitrarily many times. Wraps are able to modify the arguments and the return value of the original function. In the terminology of aspect-oriented programming, the library allows applying advices (wraps) to call join points of methods and functions in around fashion.http://www.developerhell.com/out/Behavior_driven_Testing_with_RSpechttp://www.developerhell.com/out/Behavior_driven_Testing_with_RSpecTesting fever has infected the Ruby programming community, and the infection is spreading. 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/Using_Pyke_the_Python_knowledge_enginehttp://www.developerhell.com/out/Using_Pyke_the_Python_knowledge_engineThis describes how to use pyke from within your python program.http://www.developerhell.com/out/Storing_User_Profileshttp://www.developerhell.com/out/Storing_User_ProfilesUser Profiles - The profile feature in ASP.NET 2.0 allows you to define and store per-user settings to be used throughout your application.

I have a good understanding of Python but, same as I had with JavaScript, I have little experience doing projects from the ground up in it. Before diving into the project I decided to take a look at a few Python video lectures to learn language idioms and features which I might have not heard of.http://www.developerhell.com/out/The_state_of_Python_profilers_in_two_words_Use_cProfilehttp://www.developerhell.com/out/The_state_of_Python_profilers_in_two_words_Use_cProfileThis is for people who still wonder what they should use every time. cProfile was added in Python 2.5 after much discussion about the downsides of existing profilers.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).
