Regular expressions can be used with NSPredicate that is part of Core Data, available since Mac OS X 10.4 and officially announced for iPhone OS 3.0. Cocoa's WebView and the equivalent UIWebView in Cocoa Touch both support JavaScript with regular expressions. So there sure is regular expressions available on the platforms, but how do you make it available for your own code?

Throughout this tutorial, we'll create a simple shoutbox application in CodeIgniter, and then port it over to Ruby on Rails. We'll be comparing the code between the two applications to see where they are similar, and where they differ. Learning Rails is much easier if you are already familiar with an MVC (Model, View, Controller) framework structure.

As I was checking out some flash sites for inspiration, I ran across a couple websites that had some nice navigation effects. I’m not a huge fan of wildly animated navs, but these had simple and elegant roll over effects that I liked. I decided to imitate the effect with CSS and jQuery, and would like to share this technique today.

Browsers fail to give users effective feedback when the user submits a form. Users respond by clicking the submit button over and over. The problem compounds when users find out they’ve been charged 5 times or when you receive 5 contact submissions. Bummer. The solution is to replace the submit button with a friendly message letting the user know the form is working.

The ability to drag and drop content on a page and have it save the order can make for a great user interface and is actually relatively easy to execute with a few lines of jQuery. You’ll need to include the jQuery user interface library which you can find here: Jquery Google API. All the files needed to get this up and running are in the download at the bottom of this post.

jQuery has became so powerful in reducing the number of codes required that makes me wanted to try how well this can be done using it. Personally, i wanted to check out how easy it is to create a grey out screen with a pop out box at the center of the screen. This is purely for the sake of exploring and experiencing how simple can a grey out screen be done in jQuery.
