Functional Kotlin. Extend your OOP skills and implement Functional techniques in Kotlin and Arrow
Mario Arias, Rivu Chakraborty
Functional programming makes your application faster, improves performance, and increases your productivity. Kotlin supports many of the popular and advanced functional features of functional languages. This book will cover the A-Z of functional programming in Kotlin. This book bridges the language gap for Kotlin developers by showing you how to create and consume functional constructs in Kotlin. We also bridge the domain gap by showing how functional constructs can be applied in business scenarios. We’ll take you through lambdas, pattern matching, immutability, and help you develop a deep understanding of the concepts and practices of functional programming. If you want learn to address problems using Recursion, Koltin has support for it as well. You’ll also learn how to use the funKtionale library to perform currying and lazy programming and more. Finally, you’ll learn functional design patterns and techniques that will make you a better programmer.By the end of the book, you will be more confident in your functional programming skills and will be able to apply them while programming in Kotlin.

Jakob Nielsen, Raluca Budiu
Kreuj doświadczenia użytkowników smartfonów i tabletów! Urządzenia mobilne pomimo rosnących rozmiarów wciąż są zdecydowanie mniejsze od naszych laptopów i komputerów stacjonarnych. Zaprojektowanie funkcjonalnego i eleganckiego interfejsu użytkownika na tak ograniczonej przestrzeni wymaga nie lada kunsztu. Obecnie jednak urządzenia te dają programistom nowe możliwości, a wśród nich dostęp do ekranów dotykowych. Warto dobrze wykorzystać ich potencjał! Dzięki tej książce, napisanej przez najlepszych specjalistów w branży, dowiesz się, jak najlepiej przygotować aplikację lub stronę internetową dla małych ekranów. Poznasz zalety i wady smartfonów, tabletów oraz czytników e-booków. Ponadto nauczysz się rozpoznawać typowe błędy, które obniżają doznania Twoich użytkowników w trakcie korzystania z Twojego oprogramowania, i unikać ich. A potem spojrzysz w przyszłość i przekonasz się, co może nas czekać wkrótce w dziedzinie urządzeń mobilnych. Ta książka to niezbędna pozycja dla każdego projektanta stron i aplikacji przeznaczonych na mniejsze ekrany. Poznaj: zalety i wady urządzeń mobilnych zasady tworzenia stron internetowych i aplikacji dla telefonów czy tabletów typowe problemy powodujące irytację użytkowników przyszłość branży mobilnej Bogactwo UX to klucz do sukcesu Twojej aplikacji!

Fuzzing Against the Machine. Automate vulnerability research with emulated IoT devices on QEMU
Antonio Nappa, Eduardo Blázquez
Emulation and fuzzing are among the many techniques that can be used to improve cybersecurity; however, utilizing these efficiently can be tricky. Fuzzing Against the Machine is your hands-on guide to understanding how these powerful tools and techniques work. Using a variety of real-world use cases and practical examples, this book helps you grasp the fundamental concepts of fuzzing and emulation along with advanced vulnerability research, providing you with the tools and skills needed to find security flaws in your software.The book begins by introducing you to two open source fuzzer engines: QEMU, which allows you to run software for whatever architecture you can think of, and American fuzzy lop (AFL) and its improved version AFL++. You’ll learn to combine these powerful tools to create your own emulation and fuzzing environment and then use it to discover vulnerabilities in various systems, such as iOS, Android, and Samsung's Mobile Baseband software, Shannon. After reading the introductions and setting up your environment, you’ll be able to dive into whichever chapter you want, although the topics gradually become more advanced as the book progresses.By the end of this book, you’ll have gained the skills, knowledge, and practice required to find flaws in any firmware by emulating and fuzzing it with QEMU and several fuzzing engines.

Physics is really important for game programmers who want to add realism and functionality to their games. Collision detection in particular is a problem that affects all game developers, regardless of the platform, engine, or toolkit they use.This book will teach you the concepts and formulas behind collision detection. You will also be taught how to build a simple physics engine, where Rigid Body physics is the main focus, and learn about intersection algorithms for primitive shapes.You’ll begin by building a strong foundation in mathematics that will be used throughout the book. We’ll guide you through implementing 2D and 3D primitives and show you how to perform effective collision tests for them. We then pivot to one of the harder areas of game development—collision detection and resolution. Further on, you will learn what a Physics engine is, how to set up a game window, and how to implement rendering. We’ll explore advanced physics topics such as constraint solving. You’ll also find out how to implement a rudimentary physics engine, which you can use to build an Angry Birds type of game or a more advanced game.By the end of the book, you will have implemented all primitive and some advanced collision tests, and you will be able to read on geometry and linear Algebra formulas to take forward to your own games!
