Android High Performance Programming. Click here to enter text

Emil Atanasov, Enrique López Manas, Diego Grancini

Performant applications are one of the key drivers of success in the mobile world. Users may abandon an app if it runs slowly. Learning how to build applications that balance speed and performance with functionality and UX can be a challenge; however, it's now more important than ever to get that balance right.Android High Performance will start you thinking about how to wring the most from any hardware your app is installed on, so you can increase your reach and engagement. The book begins by providing an introduction to state–of-the-art Android techniques and the importance of performance in an Android application. Then, we will explain the Android SDK tools regularly used to debug and profile Android applications. We will also learn about some advanced topics such as building layouts, multithreading, networking, and security. Battery life is one of the biggest bottlenecks in applications; and this book will show typical examples of code that exhausts battery life, how to prevent this, and how to measure battery consumption from an application in every kind of situation to ensure your apps don’t drain more than they should.This book explains techniques for building optimized and efficient systems that do not drain the battery, cause memory leaks, or slow down with time.

Instant HTML5 Geolocation How-to. Learn how to create elegant, location-aware web applications using the JavaScript Geolocation API

Benjamin Otto Werdmulle

We don't just surf the Web from our desktops any more – we take it with us, everywhere we go. Modern devices contain sophisticated hardware and software to determine the user's location. Apps such as Foursquare and Google Maps use this to create new kinds of functionality. Now, you can do this too with the HTML5 Geolocation API.Instant HTML5 Geolocation How-to is a simple guide to adding location information to your web applications. The practical, easy-to-follow recipes are designed to help you learn the ins and outs of the API. You'll learn how to use it, how it works, and how to save and display geographic information on the web.Beginning with a solid grounding in how the Geolocation API works and when to use it, you will learn how to determine, store, display, and track the user's location via a series of clear recipes.You will learn the different ways location is determined on different devices, including desktops and laptops that don't have GPS units. You'll also learn how to selectively use these different behaviours, based on the speed, accuracy, and battery life requirements of your application. You'll also get some hints about using MySQL databases to store sets of location data.Instant HTML5 Geolocation How-to will teach you everything you need to know about retrieving the location information your application needs, across multiple devices and platforms.

Hands-On Generative Adversarial Networks with PyTorch 1.x. Implement next-generation neural networks to build powerful GAN models using Python

John Hany, Greg Walters

With continuously evolving research and development, Generative Adversarial Networks (GANs) are the next big thing in the field of deep learning. This book highlights the key improvements in GANs over generative models and guides in making the best out of GANs with the help of hands-on examples.This book starts by taking you through the core concepts necessary to understand how each component of a GAN model works. You'll build your first GAN model to understand how generator and discriminator networks function. As you advance, you'll delve into a range of examples and datasets to build a variety of GAN networks using PyTorch functionalities and services, and become well-versed with architectures, training strategies, and evaluation methods for image generation, translation, and restoration. You'll even learn how to apply GAN models to solve problems in areas such as computer vision, multimedia, 3D models, and natural language processing (NLP). The book covers how to overcome the challenges faced while building generative models from scratch. Finally, you'll also discover how to train your GAN models to generate adversarial examples to attack other CNN and GAN models.By the end of this book, you will have learned how to build, train, and optimize next-generation GAN models and use them to solve a variety of real-world problems.

Test-Driven Development with Java. Create higher-quality software by writing tests first with SOLID and hexagonal architecture

Alan Mellor

Test-driven development enables developers to craft well-designed code and prevent defects. It’s a simple yet powerful tool that helps you focus on your code design, while automatically checking that your code works correctly. Mastering TDD will enable you to effectively utilize design patterns and become a proficient software architect.The book begins by explaining the basics of good code and bad code, bursting common myths, and why Test-driven development is crucial. You’ll then gradually move toward building a sample application using TDD, where you’ll apply the two key rhythms -- red, green, refactor and arrange, act, assert. Next, you’ll learn how to bring external systems such as databases under control by using dependency inversion and test doubles. As you advance, you’ll delve into advanced design techniques such as SOLID patterns, refactoring, and hexagonal architecture. You’ll also balance your use of fast, repeatable unit tests against integration tests using the test pyramid as a guide. The concluding chapters will show you how to implement TDD in real-world use cases and scenarios and develop a modern REST microservice backed by a Postgres database in Java 17.By the end of this book, you’ll be thinking differently about how you design code for simplicity and how correctness can be baked in as you go.

Learn OpenCV 4 By Building Projects. Build real-world computer vision and image processing applications with OpenCV and C++ - Second Edition

David Millán Escrivá, Vinícius G. Mendonça, Prateek Joshi

OpenCV is one of the best open source libraries available, and can help you focus on constructing complete projects on image processing, motion detection, and image segmentation. Whether you’re completely new to computer vision, or have a basic understanding of its concepts, Learn OpenCV 4 by Building Projects – Second edition will be your guide to understanding OpenCV concepts and algorithms through real-world examples and projects. You’ll begin with the installation of OpenCV and the basics of image processing. Then, you’ll cover user interfaces and get deeper into image processing. As you progress through the book, you'll learn complex computer vision algorithms and explore machine learning and face detection. The book then guides you in creating optical flow video analysis and background subtraction in complex scenes. In the concluding chapters, you'll also learn about text segmentation and recognition and understand the basics of the new and improved deep learning module.By the end of this book, you'll be familiar with the basics of Open CV, such as matrix operations, filters, and histograms, and you'll have mastered commonly used computer vision techniques to build OpenCV projects from scratch.
