Using Underscore.js with Collections

In this article Alex Pop , the author of the book, Learning Underscore.js , we will explore Underscore functionality for collections using more in-depth examples. Some of the more advanced concepts related to Underscore functions such as scope resolution and execution context will be explained. The topics of the article are as follows: Key Underscore functions revisited Searching and filtering This article assumes that you are familiar with JavaScript fundamentals such as prototypical inheritance and the built-in data types. The source code for the examples from this article is hosted online at, and you can execute the examples using the Cloud9 IDE at the address from the collections folder.

Storing and Generating Graphs of the Stored Data

In this article by Matthijs Kooijman , the author of the book Building Wireless Sensor Networks Using Arduino , we will explore some of the ways to persistently store the collected sensor data and visualize the data using convenient graphs. First, you will see how to connect your coordinator to the Internet and send its data to the Beebotte cloud platform. You will learn how to create a custom dashboard in this platform that can show you the collected data in a convenient graph format. Second, you will see how you can collect and visualize the data on your own computer instead of sending it to the Internet directly.

Apps for Different Platforms

In this article by Hoc Phan , the author of the book Ionic Cookbook , we will cover tasks related to building and publishing apps, such as: Building and publishing an app for iOS Building and publishing an app for Android Using PhoneGap Build for cross–platform

Deploying on your own server

In this article by Jack Stouffer , the author of the book Mastering Flask , you will learn how to deploy and host your application on the different options available, and the advantages and disadvantages related to them. The most common way to deploy any web app is to run it on a server that you have control over. Control in this case means access to the terminal on the server with an administrator account. This type of deployment gives you the most amount of freedom out of the other choices as it allows you to install any program or tool you wish. This is in contrast to other hosting solutions where the web server and database are chosen for you. This type of deployment also happens to be the least expensive option. The downside to this freedom is that you take the responsibility of keeping the server up, backing up user data, keeping the software on the server up to date to avoid security issues, and so on. Entire books have been written on good server management, so if this is not a responsibility that you believe you or your company can handle, it would be best if you choose one of the other deployment options. This section will be based on a Debian Linux-based server, as Linux is far and away the most popular OS for running web servers, and Debian is the most popular Linux distro (a particular combination of software and the Linux kernel released as a package). Any OS with Bash and a program called SSH (which will be introduced in the next section) will work for this article, the only differences will be the command-line programs to install software on the server.

Overview of Physics Bodies and Physics Materials

In this article by Katax Emperor and Devin Sherry , author of the book Unreal Engine Physics Essentials , we will take a deeper look at Physics Bodies in Unreal Engine 4. We will also look at some of the detailed properties available to these assets. In addition, we will discuss the following topics: Physical materials – an overview For the purposes of this article, we will continue to work with Unreal Engine 4 and the Unreal_PhyProject . Let's begin by discussing Physics Bodies in Unreal Engine 4.

Collaboration Using the GitHub Workflow

In this article by Achilleas Pipinellis , the author of the book GitHub Essentials , has come up with a workflow based on the features it provides and the power of Git. It has named it the GitHub workflow ( In this article, we will learn how to work with branches and pull requests , which is the most powerful feature of GitHub.

Lights and Effects

 In this article by Matt Smith and Chico Queiroz , authors of Unity 5.x Cookbook , we will cover the following topics: Using lights and cookie textures to simulate a cloudy day Adding a custom Reflection map to a scene Creating a laser aim with Projector and Line Renderer Reflecting surrounding objects with Reflection Probes Setting up an environment with Procedural Skybox and Directional Light

Data Around Us

 In this article by Gergely Daróczi , author of the book Mastering Data Analysis with R we will discuss Spatial data, also known as geospatial data, which identifies geographic locations, such as natural or constructed features around us. Although all observations have some spatial content, such as the location of the observation, but this is out of most data analysis tools' range due to the complex nature of spatial information; alternatively, the spatiality might not be that interesting (at first sight) in the given research topic. On the other hand, analyzing spatial data can reveal some very important underlying structures of the data, and it is well worth spending time visualizing the differences and similarities between close or far data points. In this article, we are going to help with this and will use a variety of R packages to: Retrieve geospatial information from the Internet Visualize points and polygons on a map

Designing and Building a vRealize Automation 6.2 Infrastructure

 In this article by J. Powell , the author of the book Mastering vRealize Automation 6.2 , we put together a design and build vRealize Automation 6.2 from POC to production. With the knowledge gained from this article, you should feel comfortable installing and configuring vRA. In this article, we will be covering the following topics: Proving the technology Proof of Concept Proof of Technology Pilot Designing the vRealize Automation architecture

Oracle API Management Implementation 12c

 This article by Luis Augusto Weir , the author of the book, Oracle API Management 12c Implementation , gives you a gist of what is covered in the book. At present, the digital transformation is essential for any business strategy, regardless of the industry they belong to an organization.

Writing SOLID JavaScript code with TypeScript

In this article by Remo H. Jansen , author of the book Learning TypeScript , explains that in the early days of software development, developers used to write code with procedural programing languages. In procedural programming languages, the programs follow a top to bottom approach and the logic is wrapped with functions. New styles of computer programming like modular programming or structured programming emerged when developers realized that procedural computer programs could not provide them with the desired level of abstraction, maintainability and reusability. The development community created a series of recommended practices and design patterns to improve the level of abstraction and reusability of procedural programming languages but some of these guidelines required certain level of expertise. In order to facilitate the adherence to these guidelines, a new style of computer programming known as object-oriented programming ( OOP ) was created.

Creating TFS Scheduled Jobs

In this article by Gordon Beeming , the author of the book, Team Foundation Server 2015 Customization , we are going to cover TFS scheduled jobs. The topics that we are going to cover include: Writing a TFS Job Deploying a TFS Job Removing a TFS Job You would want to write a scheduled job for any logic that needs to be run at specific times, whether it is at certain increments or at specific times of the day. A scheduled job is not the place to put logic that you would like to run as soon as some other event, such as a check-in or a work item change, occurs. It will automatically link change sets to work items based on the comments.
