How to integrate social media with your WordPress website

In this article by Karol Krol , the author of the WordPress 4.x Complete , we will look at how we can integrate our website with social media.

Bang Bang – Let's Make It Explode

In this article by Justin Plowman , author of the book 3D Game Design with Unreal Engine 4 and Blender , We started with a basic level that, when it comes right down to it, is simply two rooms connected by a hallway with a simple crate. From humble beginnings our game has grown, as have our skills. Our simple cargo ship leads the player to a larger space station level. This level includes scripted events to move the story along and a game asset that looks great and animates. However, we are not done. How do we end our journey? We blow things up, that's how! In this article we will cover the following topics: Using class blueprints to bring it all together Creating an explosion using sound effects Adding particle effects

Visualizations Using CCC

In this article by  Miguel Gaspar  the author of the book  Learning Pentaho CTools  you will learn about the  Charts Component Library  in detail. The Charts Components Library is not really a Pentaho plugin, but instead is a Chart library that Webdetails created some years ago and that Pentaho started to use on the Analyzer visualizations. It allows a great level of customization by changing the properties that are applied to the charts and perfectly integrates with CDF, CDE, and CDA.

Virtualizing Hosts and Applications

In this article by Jay LaCroix , the author of the book Mastering Ubuntu Server , you will learn how there have been a great number of advancements in the IT space in the last several decades, and a few technologies have come along that have truly revolutionized the technology industry. The author is sure few would argue that the Internet itself is by far the most revolutionary technology to come around, but another technology that has created a paradigm shift in IT is virtualization. It evolved the way we maintain our data centers, allowing us to segregate workloads into many smaller machines being run from a single server or hypervisor. Since Ubuntu features the latest advancements of the Linux kernel, virtualization is actually built right in. After installing just a few packages, we can create virtual machines on our Ubuntu Server installation without the need for a pricey license agreement or support contract. In this article, Jay will walk you through creating, running, and managing Docker containers.

Exploring Scala Performance

In this article by Michael Diamant and Vincent Theron , author of the book Scala High Performance Programming , we look at how Scala features get compiled with bytecode.

First Person Shooter Part 1 – Creating Exterior Environments

In this article by John P. Doran , the author of the book Unity 5.x Game Development Blueprints , we will be creating a first-person shooter; however, instead of shooting a gun to damage our enemies, we will be shooting a picture in a survival horror environment, similar to the Fatal Frame series of games and the recent indie title DreadOut . To get started on our project, we're first going to look at creating our level or, in this case, our environments starting with the exterior. In the game industry, there are two main roles in level creation: an environment artist and a level designer. An environment artist is a person who builds the assets that go into the environment. He/she uses tools such as 3Ds Max or Maya to create the model and then uses other tools such as Photoshop to create textures and normal maps. The level designer is responsible for taking the assets that the environment artist created and assembling them in an environment for players to enjoy. He/she designs the gameplay elements, creates the scripted events, and tests the gameplay. Typically, a level designer will create environments through a combination of scripting and using a tool that may or may not be in development as the game is being made. In our case, that tool is Unity. One important thing to note is that most companies have their own definition for different roles. In some companies, a level designer may need to create assets and an environment artist may need to create a level layout. There are also some places that hire someone to just do lighting or just to place meshes (called a mesher) because they're so good at it.

Gradle with the Java Plugin

In this article by Hubert Klein Ikkink , author of the book  Gradle Effective Implementations Guide, Second Edition , we will discuss the Java plugin provides a lot of useful tasks and properties that we can use for building a Java application or library. If we follow the convention-over-configuration support of the plugin, we don't have to write a lot of code in our Gradle build file to use it. If we want to, we can still add extra configuration options to override the default conventions defined by the plugin.
