Computer Vision and Augmented Reality in iOS
Learn how computer vision works, how augmented reality renders digital graphics into the physical world via an iPhone's camera, and how to incorporate these technologies into your own apps. This book shows you how to take full advantage of computer vision technologies. Interacting with other people online usually involves user-generated images and videos; whether it be "memes", short videos, or heavily-modified images. Before smart phones, generating this content required a professional using high-level image and video editing software. Not any more. This book will teach you to use computer vision in the most popular ways, such as for facial recognition, image to text analysis and, of course, recording a video of a dancing hot dog in your living room. Starting with the history of computer vision, image and video processing fundamentals, and an introduction to developing augmented reality applications, you'll learn to incorporate computer vision both in the content you create and t ...

Blazor, A Beginners Guide
Blazor, A Beginners Guide is intended for developers with some .NET experience. If you're coming from a non-.NET development background, you may learn some .NET basics along the way, but supplemental material around C# and .NET would be of great help to you. The book begins with the author's own perspective on WebAssembly, why it's important to have choices in web development and offers some insight on why Blazor was created. You'll then step through an overview where you'll get familiar with the framework and technology stack. As the book progresses you will see working examples that teach core concepts broadly. Later in the book, topics that require a deeper knowledge are revisited to grasp the fine details so you can make informed decisions about how your apps and components are built. The intent of the book's layout is to get you productive quickly. You should be able to navigate and create Blazor projects with ease as you read through the chapters versus having to complete t ...

Ethical Hacking
Ethical Hacking is a crash course in modern hacking techniques. It's already being used to prepare the next generation of offensive security experts. In its many hands-on labs, you'll explore crucial skills for any aspiring penetration tester, security researcher, or malware analyst. You'll begin with the basics: capturing a victim's network traffic with an ARP spoofing attack and then viewing it in Wireshark. From there, you'll deploy reverse shells that let you remotely run commands on a victim's computer, encrypt files by writing your own ransomware in Python, and fake emails like the ones used in phishing attacks. In advanced chapters, you'll learn how to fuzz for new vulnerabilities, craft trojans and rootkits, exploit websites with SQL injection, and escalate your privileges to extract credentials, which you'll use to traverse a private network. You'll work with a wide range of professional penetration testing tools - and learn to write your own tools in Python - as you pra ...
