Here are 4 JavaScript Tutorials at syger.it. All the scripts in these JavaScript tutorials are available for download as two compressed archives Scripts.zip and AspScripts.zip. These JavaScript tutorials are designed to provide an overview, with coding examples, of the some of the power of the JavaScript programming/scripting language. They are not just aimed at the developer who works on code for the browser or client side, the tutorials contain presentations to classic ASP developers, in an attempt to move them away from VBScript and towards JavaScript, for web application development.


JavaScript Introspection
This JavaScript tutorial introduces you to JavaScript introspection. In computing, type introspection is a capability of some object-oriented programming languages to determine the type of an object at runtime. Being able to interrogate an object to discover its properties can be a great help when debugging.
 - The Namespace
 - The typeOf Function
 - The exists Function
 - The introspect Function
 - Using the Code


JavaScript Inheritance
This JavaScript tutorial discusses JavaScript inheritance. However, since JavaScript is a class free programming language, the mechanism used is prototypal, rather than classical. For this tutorial, you will be shown how to add functions to the String object.
 - The Extensions Code
 - Using the Code


JavaScript Closures
This JavaScript tutorial takes a look at JavaScript closures, which is an extremely powerful property of the language. In JavaScript, this means that an inner function always has access to the variables and parameters of its outer function, even after the outer function has returned.
 - The Problem
 - The Solution
 - The Closure Code
 - Using the Code


XML generator JavaScript Library
This final JavaScript tutorial explains the XML generator JavaScript library. This library is designed to produce XML. This is by far the largest of the tutorials, so it is split into three sections as below:
 - JavaScript Library Design
 - JavaScript Library Code
 - JavaScript Library Example

Here are 2 Ruby Tutorials and 3 Ruby on Rails Tutorials located at the LUG Villafranca Programming Course website. These Ruby and Ruby On Railes tutorials give you an excellent grounding and understanding on using Ruby and Ruby On Rails to build web applications. Ruby On Rails is an open source Ruby framework for developing database-backed web applications. You will need to download and install the Ruby Interpreter, and you will also need to install Ruby on Rails. In addition, these tutorials use RMagick version 2.0.2, which is explained in this FAQ, and  SQLite 3.1.2.1, which is explained in this How-to. Windows users will need both the .exe and .dll versions of SQLite. The Ruby on Rails Wiki page also gives helpful information for SQLite. Source code is provided for all of these tutorials. Also, the whole programming course, which includes JavaScript tutorials, can be downloaded as pdf which is 2.28 Mb and explained in 125 pages.


Ruby Full Immersion
This lesson will give a very brief overview of the language, noting important differences from JavaScript where necessary. The first, and probably most important difference from JavaScript, is that Ruby runs on the operating system itself, rather than within a browser.


Ruby and Ajax
Now we can start using Ruby to create our first web application. We previously used the Prototype and script.aculo.us libraries to dynamically modify an XHTML page, now we'll use Ajax via the script.aculo.us Ajax.Autocompleter to 'talk' to a simple Ruby web application. This lesson will introduce you to WEBrick, the Ruby web server, HTML forms, the ERB templating system, and Ajax.


Review of Ruby, Overview of Ruby on Rails
The last two lessons presented a whirlwind guide to Ruby, demonstrating a simple command line program, and a simple web application. That was a lot of material to digest, so in this lesson we'll make a short review of the important things we learned, and explain iterators and code blocks in a little more detail, since they caused some problems for some of the students. As we still have much ground to cover, half of this week's lesson is also dedicated to an overview of the Ruby on Rails framework, which we'll be using in the next two lessons to construct a more complicated web application.


Ruby on Rails, Part 1
This lesson starts us on a two part adventure building a web application using Ruby and the Ruby on Rails framework. We will build a web application for multiple users which allows them to upload images into albums. The complete source files for this lesson can be found at LUGPC9.zip
 - The WebAlbum Application
 - Reality Check
 - Using Rails Generators
 - Our First User
 - Pause for Thought
 - The Master Layout Template
 - Controllers and Helpers
 - First Release


Ruby on Rails, Part 2
This lesson concludes the two part adventure building a web application using Ruby and the Ruby on Rails framework. The next step will be to create another two classes that make up our data model, namely albums and pictures. The complete source files for this lesson can be found at LUGPC10.zip
 - Creating the Albums and Pictures
 - The Album Controller
 - The Album Views
 - The Album Model
 - The First (and Second) Album
 - Let's Add Some Pictures
 - The Picture Controller
 - Picture Controller and RMagick
 - The Picture Views
 - Finally, Some Configuration
 - Adding Some Spice with Lightbox
 - The Results
