Creating an Animated Gauge with CSS3

In web application development, gauges can be useful for showing complicated or dynamic data in a visual or intuitive way. In this article by Sandro Paganotti, author of  Designing Next Generation Web Projects with CSS3, we'll learn how to create a fully customizable animated gauge that can respond to real-time changes. We'll also discuss techniques to port this type of widget for support in older web browsers. We'll start by learning about a cool SASS enhancement called Compass; this is another way to deal with CSS3 experimental prefixes. The following is the list of the topics we'll discuss:

• A basic gauge structure

• Using Compass

• Using rem

• Moving the arrow

• Animating the arrow

• Dealing with older browsers

Parallel Dimensions – Branching with Git

Cheap branching and merging are the two most well known and applauded features of Git. In this article by Ravishankar Somasundaram, author of Git: Version Control for Everyone Beginner's Guide, we shall see what branching is, why you need a branch, and when you need a branch. Also we shall see how to merge branches when needed.

All these are explored from an organization's point of view. We will also learn and practice methods to simplify our work by:

• Creating simple alias for frequently used lengthy commands

• Chaining of multiple commands for frequently used workflows

Remotely Preview and test mobile web pages on actual devices with Adobe Edge Inspect

Mobile web testing is currently a really time consuming and cumbersome process as there are no direct debugging tools available with mobile web browsers. Since mobile devices vary so much it is important to ensure that your web page looks as intended across the multiple mobile devices that you are targeting for your audience. Adobe Edge Inspect is a perfect tool for frontend web developers and designers who are developing for mobile devices, allowing them to simultaneously test on numerous devices in real time as they develop without learning anything new.

With Adobe Edge Inspect you can pair multiple mobile devices with your computer and browse in Google Chrome on your computer and all the paired mobile devices stay in sync. This means that any page you open in Chrome either from your local HTTP web server (via localhost) or a production server, that same page is opened synchronously in all the paired mobile devices. After that you can target any mobile device for inspection and start remote testing, make changes to the HTML markup, CSS style rules, and JavaScript, and instantly see the changes in the targeted mobile devices.

In this article by Joseph Khan, author of Instant Adobe Edge Inspect Starter, we will talk on the most important feature of Adobe Edge Inspect, that is, how we can remotely preview, inspect, and debug a mobile web page. So let's get started.

Inter-process Communication

In this article by Mark Nelson and Tanya Williams, the authors of Oracle BPM Suite 11g: Advanced BPMN Topics , you will learn to convert a video into any of the formats needed for HTML5 Video playback.

Inter-process Communication introduces us to the theory of how processes can communicate with each other and with other components. A number of topics are covered such as: conversations—what they are, and the default conversation.

Welcome to our exploration of some of the advanced topics in BPMN. When we set out to write this book, we chose the areas where we see the most confusion and difficulty in understanding how to use BPMN. We will present theory and also build practical exercises together so that you can see how the theory is applied. Let's start our journey by building an understanding of inter-process communication.

Titanium Best Practices

With the release of Titanium 2.0, a lot of new features and APIs were introduced, though the biggest change is the fully loaded integration of CommonJS. CommonJS started to appear at the end of 2011 and has meant a complete rewrite of the best practices and the application structure. Best practices are always open to interpretation; they are a good starting point but not a definitive solution.

With so many computer programming languages around, people are always trying to find better means to improve the way developers write code and come up with a standard set of practices. Some companies take this policy to a level where they define a complete set of standards. However, for most developers there are no predefined rules laid out or enforced, so they work out their own.

Not following a set of standards or best practices has various consequences, ranging from bad code layout (not a crime, unless you meet the next person to modify the code) to badly performing applications. To define these standards for Titanium we have to start with CommonJS, as it plays a major role in the whole framework. This article by Boydlee Pollentine and Trevor Ward, authors of Appcelerator Titanium: Patterns and Best Practices, looks at best practices directly as they relate to the Titanium Mobile API itself, before diving into writing Titanium applications using CommonJS.

Getting started with using Chef

Now that you have a functioning Chef Server running and the tools needed to interact with it, we will discuss the steps involved in setting up nodes that talk to the Chef service and will use the information provided to install software and set up the server.

This article by John Ewart, author of Instant Chef Starter will take you through the process of using Chef to provision a new Ubuntu 12.10 server and set it up as a LAMP (Linux, Apache, MySQL, and PHP) server as this is a very simple and quite common server configuration at the moment. The basic steps will be as follows:

1. Setting up the server.

2. Downloading and examining cookbooks.

3. Uploading cookbooks into your Chef Server.

4. Creating and assigning roles to the node.

5. Completing the process by applying changes to the node.

Wireshark: Working with Packet Streams

As you start to use Wireshark, you will realize that there are a wide variety of things that you can do with it. This article by Abhinav Singh, author of Instant Wireshark Starter [Instant], will teach you all about working with packet streams, the most commonly performed tasks and most commonly used feature in Wireshark.
