This article by Aaron Martinez and Enrique Fernández, authors of the book Learning ROS for Robotics Programming, talks about configuring your robot to use it in the navigation stack. Now, in this article, you will learn something that is probably one of the most powerful features in ROS, something that will let you move your robot autonomously.
Thanks to the community and the shared code, ROS has many algorithms that can be used for navigation.
First of all, in this chapter, you will learn all the necessary ways to configure the navigation stack with your robot. In particular, we will cover the following items in this article:
- Introduction to the navigation stacks and their powerful capabilities—clearly one of the greatest pieces of software that comes with ROS.
- The TF is explained in order to show how to transform from the frame of one physical element to the other; for example, the data received using a sensor or the command for the desired position of an actuator.
- We will see how to create a laser driver or simulate it.
- We will learn how the odometry is computed and published, and how Gazebo provides it.
- A base controller will be presented, including a detailed description of how to create one for your robot.
- We will see how to execute SLAM with ROS. That is, we will show you how you can build a map from the environment with your robot as it moves through it.
- Finally, you will be able to localize your robot in the map using the localization algorithms of the navigation stack.

In this article, by Willie L. Pritchett, author of the book Kali Linux Cookbook, we will learn about the various wireless attacks. These days, wireless networks are everywhere. With users being on the go like never before, having to remain stationary because of having to plug into an Ethernet cable to gain Internet access is not feasible. For this convenience, there is a price to be paid; wireless connections are not as secure as Ethernet connections. In this article, we will explore various methods for manipulating radio network traffic including mobile phones and wireless networks.
We will cover the following topics in this article:
- Wireless network WEP cracking
- Wireless network WPA/WPA2 cracking
- Automating wireless network cracking
- Accessing clients using a fake AP
- URL traffic manipulation
- Port redirection
- Sniffing network traffic
For those people who get sweaty palms just thinking of the word script, wipe your hands and relax. In this article, written by Terry Norton, author of the book Learning C# by Developing Games with Unity 3D, terms that are already familiar to you will be used to introduce the building blocks of programming.
A programming language such as C# can appear to be very complicated at first but in reality, there are two parts that form its foundation. These parts are variables and methods. Therefore, understanding these critical parts is a prerequisite for learning any of the other features of C#. Being as critical as they are, they are very simple concepts to understand. Using these variable and method foundation pieces, we'll be introduced to the C# building blocks used to create Unity scripts.
- Using variables in a script
- Using methods in a script
- The class which is a container for variables and methods
- Turning a script into a Component
- Components communicating using the Dot Syntax
Let's have a look at these primary concepts.Read Introducing the Building Blocks for Unity Scripts in full
SproutCore has actually been around for quite a long time in terms of the web, having been created by entrepreneur Charles Jolley, back in 2007. Charles created SproutCore to build a mail client, but was soon hired by Apple to grow the framework further and develop several even larger scale applications. Indeed you will likely recognize some of these web applications and may even remember the amazement when people first saw SproutCore apps such as mobileMe delivering a native-like look and feel in the browser without the use of plug-ins.
Until then, the Web 2.0 movement had largely failed to deliver on its promise of replacing the software of the desktop. Of course there are exceptions, but overall, the slew of web 2 apps that appeared were slow and clunky and lacked a lot of the basic features and refinement we had expected in the software. Oddly enough as mobile has gained in popularity, the advancement of web apps has actually slowed down. For instance, compared to the desktop, the network latency for mobile is horrendous and the type of web apps that are delivered a page at a time from a server are almost unusable.
As an open source framework, SproutCore gains experience in real world deployments and grows as professionals contribute that experience back into the source for us to use. That is why we're here and that is why whether you're building a new multi-platform social app or replacing an outdated internal management tool, now is the best time to learn about SproutCore.
In this article by Tyler Keating, the author of the article SproutCore Web Application Development, we will cover the following:
- Understanding the SproutCore approach
- Knowing when SproutCore is the right choice
- Building your first SproutCore application:
- Installing SproutCore
- Creating a project
- Adding an app to the project
- Designing your user interface
- Modeling your data
- Connecting it all together
- Working with user input

This article by Paolo Ciccone, author of the book The Complete Guide to DAZ Studio 4, introduces you to morphs.
A morph is a modification of a geometric model that alters its original shape. Using morphs, we can change any character into something completely different. Studio makes this operation as simple as moving sliders on the screen.
In this article we will have a look at the following topics:
- Applying morphs
- Mixing morphs to create new characters
- Saving morph presets for future use
