Optimizing for Vertical Search : Mobile, Video & Multimedia Search

Mobile search optimization is a growing market. Outside the United States, where mobile device usage has a much higher level of penetration, this discipline is already very important. Within the United States, mobile device usage is growing rapidly, so it is in the process of becoming very important there as well.

Programming WCF Services : Data Contracts - Collections (part 2) - The CollectionDataContract Attribute & Dictionaries

A dictionary is a special type of collection that maps one data instance to another. As such, dictionaries do not marshal well either as arrays or as lists. Not surprisingly, dictionaries get their own representation in WCF.

Programming WCF Services : Data Contracts - Collections (part 1) - Concrete Collections & Custom Collections

All of the built-in collections in .NET, such as the array, the list, and the stack, support these interfaces. A data contract can include a collection as a data member, and a service contract can define operations that interact with a collection directly.

iPhone Programming : The Image Picker View Controller - Adding the Image Picker to the City Guide Application

In this section, we’ll continue to build on our City Guide application. Either of the two versions of the application we now have will do, as all of the changes we’re going to make will be confined to the AddCityController class.

iPhone Programming : Other View Controllers - Modal View Controllers

You’ll have seen a modal controller in action many times when using your iPhone. A view slides in from the bottom of the screen and is usually dismissed with a Done button at the top of the screen

jQuery 1.3 : DOM Manipulation - Inserting new elements

jQuery has two methods for inserting elements before other elements: .insertBefore() and .before(). These two methods have the same function; their difference lies only in how they are chained to other methods.

jQuery 1.3 : DOM Manipulation - Manipulating attributes

The class attribute is only one of several attributes that we may need to access or change: for example, id and rel and href. For manipulating these attributes, jQuery provides the .attr() and .removeAttr() methods

DirectX 10 Game Programming : Adding the DirectX Libraries

You have all the code you need to create your first DirectX application. Before you can compile and run this, you have to do one more thing: link in the DirectX libraries.

jQuery 1.3 : AJAX - Additional options

The AJAX toolbox provided by jQuery is well-stocked. We've covered several of the available options, but we've just scratched the surface. While there are too many variants to cover here, we will give an overview of some of the more prominent ways to customize AJAX communications.

jQuery 1.3 : AJAX and events & Security limitations

For all its utility in crafting dynamic web applications, XMLHttpRequest (the underlying browser technology behind jQuery's AJAX implementation) is subject to strict boundaries.

jQuery 1.3 : AJAX - Keeping an eye on the request

Sending data to the server often involves the user filling out forms. Rather than relying on the normal form submission mechanism, which will load the response in the entire browser window, we can use jQuery's AJAX toolkit to submit the form asynchronously and place the response inside the current page.

jQuery 1.3 : AJAX - Passing data to the server

iPhone Programming : Other View Controllers - Tab Bar Applications

If you need to provide a number of different views on the same data set, or separately present a number of different tasks relating to your application, Apple recommends using a tab bar application

iPhone Programming : Other View Controllers - Utility Applications

The Xcode Utility Application template implements the main view and gives the user access to a flipside view. It is one of the most extensive templates in Xcode and it implements a fully working utility application, which is fortunate as the documentation Apple provides regarding this type of application is otherwise somewhat lacking in details.

iPhone Programming : Table-View-Based Applications - Adding a City View

You might have a nice navigation bar, but it doesn’t do any navigation yet, and after backing out of the changes you made to the tableView:didSelectRowAtIndexPath: method to present a pop up, the code doesn’t tell you about the selected city anymore.

iPhone Programming : Table-View-Based Applications - Adding Navigation Controls to the Application

This means we have to add a UINavigationController to the application. If you’ve used many iPhone apps, you’ll be familiar with this interface; it’s one of the most commonly used iPhone design interface patterns

iPad SDK : Popovers - Popover Preparations

So far, Dudel serves as a nice demo of a few features, but it's extremely limited in comparison to the vector-drawing applications that have been around for decades.

iPad SDK : Preparing Dudel for a New Tool (part 5) - Rendering Multiple Styles

At this point, lacking a standard GUI widget that gives us anything like a WYSIWYG display while editing the text, there's no really nice way to enter rich text as you can in a word processor, with buttons to change fonts or set colors.

iPad SDK : Preparing Dudel for a New Tool (part 4) - Creating a New Drawable Class

You may recognize some pieces of the draw method. We create an attributed string and set its color, use it to create a CTFramesetterRef, and then use that to create a CTFrameRef.

jQuery 1.3 : AJAX - Loading data on demand (part 3) - Loading an XML document

XML is part of the acronym AJAX, but we haven't actually loaded any XML yet. Doing so is straightforward, and mirrors the JSON technique fairly closely

jQuery 1.3 : AJAX - Loading data on demand (part 2) - Working with JavaScript objects

Pulling in fully-formed HTML on demand is very convenient, but there are times when we want our script to be able to do some processing of the data before it is displayed.

jQuery 1.3 : AJAX - Loading data on demand (part 1) - Appending HTML

AJAX applications are often no more than a request for a chunk of HTML. This technique, sometimes referred to as AHAH (Asynchronous HTTP and HTML), is almost trivial to implement with jQuery.

Coding JavaScript for Mobile Browsers (part 13) - Zoom and rotate gestures

The swipe (also known as flip) gesture is a touch-based browser technique typically used for going forward and backward. For example, it is used in many photo galleries to change the currently displayed image, and in presentations to move from slide to slide

Coding JavaScript for Mobile Browsers (part 12) - Swipe gesture

Coding JavaScript for Mobile Browsers (part 11)

Key events—onkeypress, onkeyup, and onkeydown—allow us to detect keypresses over the whole page (body) or in one element (generally, a text input).

Coding JavaScript for Mobile Browsers (part 10) - Event Handling

One of the most frequently used features of JavaScript is event handling, whether we define it inside the HTML document or by using code.

iPad SDK : Preparing Dudel for a New Tool (part 3) - Creating the Text Tool

With that in place, we can now create the TextTool class itself. This class is a lot like the RectangleTool class, but with an extra twist: When the user finishes drawing a rectangle, this tool switches into text-editing mode by placing a UITextView at the location where the rectangle was drawn

iPad SDK : Preparing Dudel for a New Tool (part 2) - Implementing Changes to the Controller Class

Those are all the changes our controller class needs in order to handle the new tool. Next, let's update the ToolDelegate protocol to match the new bit of functionality in the controller

Coding JavaScript for Mobile Browsers (part 9) - Scripting Styles

Changing content with JavaScript is useful, but sometimes it’s easier to use styles from JavaScript to make things appear and disappear and change their appearance.

Coding JavaScript for Mobile Browsers (part 8) - DOM

The Document Object Model is an increasingly common part of mobile development.
