Optimizing JavaScript for iOS Hybrid Apps

In this article by Chad R. Adams , author of the book, Mastering JavaScript High Performance , we are going to take a look at the process of optimizing JavaScript for iOS web apps (also known as hybrid apps). We will take a look at some common ways of debugging and optimizing JavaScript and page performance, both in a device's web browser and a standalone app's web view. Also, we'll take a look at the Apple Web Inspector and see how to use it for iOS development. Finally, we will also gain a bit of understanding about building a hybrid app and learn the tools that help to better build JavaScript-focused apps for iOS. Moreover, we'll learn about a class that might help us further in this. We are going to learn about the following topics in the article: Getting ready for iOS development iOS hybrid development

Dealing with Legacy Code

In this article by Arun Ravindran , author of the book Django Best Practices and Design Patterns , we will discuss the following topics: Reading a Django code base Discovering relevant documentation Incremental changes versus full rewrites Writing tests before changing code Legacy database integration

Getting Started

In this article by Mark Dunkerley , author of the book  Learning AirWatch , you will get a full understanding of all the tools included in Enterprise Mobility Management ( EMM ) with AirWatch by VMware's mobile management suite. We will go through each of the toolsets available to ensure that you understand what is available and how to set up and configure each of them. The intention of this book is not to dive into extreme detail of AirWatch's EMM but to give you the knowledge needed to understand, represent, and set up the configurations. Understand that the mobile space is an extremely fast-growing market and some of the information might have already been updated. The information presented in this book is current as of AirWatch 7.3. In this article, we will take a look at what is needed to get started with AirWatch; we will explore the different licensing options and what hosting methods are available with support. We will also look at the different types of devices that are supported along with the different profile options to manage the devices. The following will be covered in this article: An overview of AirWatch Management suite options Hosting options Support options Learning and deployment services Supported devices Device ownership

Securing your Elastix System

Getting Started with Intel Galileo

In this article by Onur Dundar , author of the book Home Automation with Intel Galileo , we will see how to develop home automation examples using the Intel Galileo development board along with the existing home automation sensors and devices. In the book, a good review of Intel Galileo will be provided, which will teach you to develop native C/C++ applications for Intel Galileo. After a good introduction to Intel Galileo, we will review home automation's history, concepts, technology, and current trends. When we have an understanding of home automation and the supporting technologies, we will develop some examples on two main concepts of home automation: energy management and security. We will build some examples under energy management using electrical switches, light bulbs and switches, as well as temperature sensors. For security, we will use motion, water leak sensors, and a camera to create some examples. For all the examples, we will develop simple applications with C and C++. Finally, when we are done building good and working examples, we will work on supporting software and technologies to create more user friendly home automation software. In this article, we will take a look at the Intel Galileo development board, which will be the device that we will use to build all our applications; also, we will configure our host PC environment for software development. The following are the prerequisites for this article: A Linux PC for development purposes. All our work has been done on an Ubuntu 12.04 host computer, for this article and others as well. (If you use newer versions of Ubuntu, you might encounter problems with some things in this article.) An Intel Galileo (Gen 2) development board with its power adapter. A USB-to-TTL serial UART converter cable; the suggested cable is TTL-232R-3V3 to connect to the Intel Galileo Gen 2 board and your host system. You can see an example of a USB-to-TTL serial UART cable at If you are going to use Intel Galileo Gen 1, you will need a 3.5 mm jack-to-UART cable. You can see the mentioned cable at An Ethernet cable connected to your modem or switch in order to connect Intel Galileo to the local network of your workplace. A microSD card. Intel Galileo supports microSD cards up to 32 GB storage.

PostgreSQL – New Features

In this article, Jayadevan Maymala , author of the book, PostgreSQL for Data Architects , you will see how to troubleshoot the initial hiccups faced by people who are new to PostgreSQL. We will look at a few useful, but not commonly used data types. We will also cover pgbadger, a nifty third-party tool that can run through a PostgreSQL log. This tool can tell us a lot about what is happening in the cluster. Also, we will look at a few key features that are part of PostgreSQL 9.4 release. We will cover a couple of useful extensions.

PostgreSQL Cookbook - High Availability and Replication

In this article by Chitij Chauhan , author of the book PostgreSQL Cookbook , we will talk about various high availability and replication solutions, including some popular third-party replication tools such as Slony-I and Londiste. In this article, we will cover the following recipes: Setting up hot streaming replication Replication using Slony-I Replication using Londiste
