Responsive Design with Media Queries

It is a multimedia world. People experience and interact with web content with a variety of media, ranging from large-screen projections of websites to hand-held devices. This presents specific challenges for web designers.

One of those challenges revolves around designing pages that are accessible, inviting, and functional at highly varying sizes. A page with centered content, sidebars on the left and the right, and text flowing around images may be inviting on a laptop, but a jumbled mess on an iPhone.

With the advent of HTML5 and CSS3, it is possible to design pages that detect the size of a viewing device (the viewport), and to present unique page layouts customized for that device. So, for example, you can create three alternative views of a page—one for smart phones, one for tablets, and one for full-sized monitors. The approach is referred to as responsive design. The CSS3 technique for implementing it is a Media Query.

In this article by David Karlins the author of Dreamweaver CS6 Mobile and Web Development with HTML5, CSS3, and jQuery Mobile, we'll learn to design pages in Dreamweaver that detect media viewports using Dreamweaver-generated Media Queries, and present appropriate page designs tailored to the visitor's viewing environment.

While doing that, we will:

• Use Dreamweaver's Multiscreen Preview window to preview how sites will look in different viewports

• Customize Multiscreen Preview for specific devices

• Create multiple styles for differently sized viewing devices with Dreamweaver's Media Queries

Atmosfall – Managing Game Progress with Coroutines

In this article by Nevin Flanagan, author of Corona SDK Hotshot, we look at managing information with the use of physics engine. If you're a long-time or low-level programmer, you may be accustomed to controlling the core of your game loop; if you're more used to recent game engines, you may have learned to juggle complex information about what actors in your game are doing at any given moment. In Corona, the combination of a separately-tracked physics engine and the versatility of Lua will, when used correctly, manage this information for you.

Using jQuery and jQueryUI Widget Factory plugins with RequireJS

This article by Greg Franko, the author of Instant Dependency Management with Require JS How-to, In this section we will demonstrate how to use jQuery and jQueryUI Widget Factory plugins with Require.js. In case you are not familiar, the jQueryUI Widget Factory provides a consistent API for building jQuery plugins and has become a popular tool for jQuery plugin authors.

Since more and more jQuery plugins use the jQueryUI Widget Factory, it is necessary to understand how to use these jQuery plugins with AMD loaders, such as Require.js.

Python Libraries for Geospatial Development

This article by Erik Westra the author of Python Geospatial Development - Second Edition, examines a number of libraries and other tools which can be used for geospatial development in Python.

More specifically, we will cover:

• Python libraries for reading and writing geospatial data

• Python libraries for dealing with map projections

• Libraries for analyzing and manipulating geospatial data directly within your Python programs

• Tools for visualizing geospatial data

Note that there are two types of geospatial tools which are not discussed in this article: geospatial databases and geospatial web toolkits. Both of these will be examined in detail later in this book.

An Introduction to Risk Analysis

Security is a process that requires the integration of security into business processes to ensure enterprise risk is minimized to an acceptable level. Security as a process is an approach that highlights the integration of security and business initiatives to reduce the security impact of implementations and changes to the enterprise environment. This article by Aaron Woody, author of Enterprise Security: A Data-Centric Approach to Securing the Enterprise, will introduce the concept of using risk analysis to drive security decisions.

Architecture of FreeSWITCH

Welcome to FreeSWITCH! If you are reading this, then undoubtedly you are interested in things like telecommunications and Voice over Internet Protocol (VoIP). FreeSWITCH is revolutionary software created during a telephony revolution. Before looking at the architecture of this powerful software, let's take a look at the colorful world of telecommunications. This will help to put FreeSWITCH into perspective. This article is written by

In this article by ,Anthony Minessale,Michael S Collins,Darren Schreiber,Raymond Chandler, authors of IBM Cognos Workspace Advanced we will cover:

• A telephony revolution

• Advantages of FreeSWITCH

• Endpoint and Dialplan modules

• How FreeSWITCH simplifies complex applications like voicemail

So, what is KineticJS?

In this article by Andrey Kovalenko, the author of the book, Instant KineticJS Starter, we will learn about the basics of KineticJS.

In order to understand what KineticJS is, you must be familiar with JavaScript development and should know the basics of HTML5 Canvas programming. KineticJS is a JavaScript library that helps us simplify the development of interactive HTML5 applications. In this case interactive applications are different 2D applications such as games, image editors, interactive maps, cartoons, and more (just turn on your imagination). From a technical point of view it is an extension to the HTML5 Canvas 2D context in the form of a JavaScript library. In addition, your application will work on all browsers that support HTML5, and even on mobile devices.
