Pro Data Mashup for Power BI
This book provides all you need to find data from external sources and load and transform that data into Power BI where you can mine it for business insights and a competitive edge. This ranges from connecting to corporate databases such as Azure SQL and SQL Server to file-based data sources, and cloud- and web-based data sources. The book also explains the use of Direct Query and Live Connect to establish instant connections to databases and data warehouses and avoid loading data. The book provides detailed guidance on techniques for transforming inbound data into normalized data sets that are easy to query and analyze. This covers data cleansing, data modification, and standardization as well as merging source data into robust data structures that can feed into your data model. You will learn how to pivot and transpose data and extrapolate missing values as well as harness external programs such as R and Python into a Power Query data flow. You also will see how to handle errors ...

Just React!
Here is your perfect companion for learning about and developing React applications. This book introduces concepts innovatively, using real-world examples based on the most recommended practices to help you establish a firm foundation. This comprehensive approach provides a strong focus on building components by using React hooks. You'll begin by learning web fundamentals, next-generation JavaScript, and how React fits into this. In the chapters that follow, you'll build a React application from scratch and learn about JSX, components, props, state management, prop drilling, context, and lifecycle events. Along the way you'll build a multi-component app and see how the components interact. Debugging and styling React applications are also discussed. You'll then take an in depth look at React hooks and see how to create a custom hook. There is also a penultimate chapter that explores important concepts such as routing and authentication. The book concludes with a review of some ex ...

Image Processing for Engineers
This is an image processing textbook with a difference. Instead of just a picture gallery of before-and-after images, we provide (on the accompanying website) MATLAB programs (.m files) and images (.mat files) for each of the examples. These allow the reader to experiment with various parameters, such as noise strength, and see their effect on the image processing procedure. We also provide general MATLAB programs, and Javascript versions of them, for many of the image processing procedures presented in this book. We believe studying image processing without actually performing it is like studying cooking without turning on an oven. Designed for a course on image processing (IP) aimed at both graduate students as well as undergraduates in their senior year, in any field of engineering, this book starts with an overview in Chapter 1 of how imaging sensors - from cameras to radars to MRIs and CAT - form images, and then proceeds to cover a wide array of image processing topics. The IP ...

Build a Binary Clock with Elixir and Nerves
Want to get better at coding Elixir? Write a hardware project with Nerves. As you build this binary clock, you'll build in resiliency using OTP, the same libraries powering many commercial phone switches. You'll attack complexity the way the experts do, using a layered approach. You'll sharpen your debugging skills by taking small, easily verified steps toward your goal. When you're done, you'll have a working binary clock and a good appreciation of the work that goes into a hardware system. You'll also be able to apply that understanding to every new line of Elixir you write. Combining software with hardware can be frustrating, but you can become proficient in no time by taking a simple, logical approach. Blinking a single LED is the traditional "Hello-World" of embedded systems. Building your own binary clock is the logical next step. It blinks groupings of LEDs based on the system time. This guide walks you through a working project using the techniques used by experts who build ...

Load Balancing in the Cloud
Use of redundant servers has long been a solution for meeting sudden spikes in demand, machine failures, and outages. Cloud services greatly reduce the cost and hassle of provisioning redundant equipment and load balancers and give you the ability to deal with separate network, application, and client-side loads. But today there are many options to consider, and you have to determine which cloud service (or services) will meet your company's unique needs. With this ebook, author Derek DeJonghe from RightBrain Networks delivers a practical guide to load balancing services in the cloud. In this dynamic environment, where machines are frequently provisioned and decommissioned to meet user demand, you need a load balancer that can intelligently distribute traffic. This ebook walks you through the several options, including the use of the NGINX software load balancer. ...
