Shader programming has been the largest revolution in graphics programming. OpenGL Shading Language (abbreviated: GLSL or GLslang), is a high-level shading language based on the syntax of the C programming language.With GLSL you can execute code on your GPU (aka graphics card). More sophisticated effects can be achieved with this technique.Therefore, knowing how OpenGL works and how each shader type interacts with each other, as well as how they are integrated into the system, is imperative for graphic programmers. This knowledge is crucial in order to be familiar with the mechanisms for rendering 3D objects.GLSL Essentials is the only book on the market that teaches you about shaders from the very beginning. It shows you how graphics programming has evolved, in order to understand why you need each stage in the Graphics Rendering Pipeline, and how to manage it in a simple but concise way. This book explains how shaders work in a step-by-step manner, with an explanation of how they interact with the application assets at each stage.This book will take you through the graphics pipeline and will describe each section in an interactive and clear way. You will learn how the OpenGL state machine works and all its relevant stages. Vertex shaders, fragment shaders, and geometry shaders will be covered, as well some use cases and an introduction to the math needed for lighting algorithms or transforms. Generic GPU programming (GPGPU) will also be covered.After reading GLSL Essentials you will be ready to generate any rendering effect you need.

Embedded computers have become very complex in the last few years and developers need to easily manage them by focusing on how to solve a problem without wasting time in finding supported peripherals or learning how to manage them. The main challenge with experienced embedded programmers and engineers is really how long it takes to turn an idea into reality, and we show you exactly how to do it. This book shows how to interact with external environments through specific peripherals used in the industry. We will use the latest Linux kernel release 4.4.x and Debian/Ubuntu distributions (with embedded distributions like OpenWrt and Yocto).The book will present popular boards in the industry that are user-friendly to base the rest of the projects on - BeagleBone Black, SAMA5D3 Xplained, Wandboard and system-on-chip manufacturers.Readers will be able to take their first steps in programming the embedded platforms, using C, Bash, and Python/PHP languages in order to get access to the external peripherals. More about using and programming device driver and accessing the peripherals will be covered to lay a strong foundation. The readers will learn how to read/write data from/to the external environment by using both C programs or a scripting language (Bash/PHP/Python) and how to configure a device driver for a specific hardware.After finishing this book, the readers will be able to gain a good knowledge level and understanding of writing, configuring, and managing drivers, controlling and monitoring applications with the help of efficient/quick programming and will be able to apply these skills into real-world projects.

Go Cookbook. Build modular, readable, and testable applications in Go
Aaron Torres
Go (a.k.a. Golang) is a statically-typed programming language first developed at Google. It is derived from C with additional features such as garbage collection, type safety, dynamic-typing capabilities, additional built-in types, and a large standard library.This book takes off where basic tutorials on the language leave off. You can immediately put into practice some of the more advanced concepts and libraries offered by the language while avoiding some of the common mistakes for new Go developers. The book covers basic type and error handling. It explores applications that interact with users, such as websites, command-line tools, or via the file system. It demonstrates how to handle advanced topics such as parallelism, distributed systems, and performance tuning. Lastly, it finishes with reactive and serverless programming in Go.
Go Design Patterns. Best practices in software development and CSP
Mario Castro Contreras
Go is a multi-paradigm programming language that has built-in facilities to create concurrent applications. Design patterns allow developers to efficiently address common problems faced during developing applications. Go Design Patterns will provide readers with a reference point to software design patterns and CSP concurrency design patterns to help them build applications in a more idiomatic, robust, and convenient way in Go. The book starts with a brief introduction to Go programming essentials and quickly moves on to explain the idea behind the creation of design patterns and how they appeared in the 90’s as a common language between developers to solve common tasks in object-oriented programming languages. You will then learn how to apply the 23 Gang of Four (GoF) design patterns in Go and also learn about CSP concurrency patterns, the killer feature in Go that has helped Google develop software to maintain thousands of servers. With all of this the book will enable you to understand and apply design patterns in an idiomatic way that will produce concise, readable, and maintainable software.

Krzysztof Rybiński
Gdy polski rynek okazuje się zbyt mały… Kiedy firma zaczyna spoglądać z ciekawością w stronę zagranicznego odbiorcy, zaczynają się koszty i kłopoty. To prawda, ale ekspansję na rynki zagraniczne rozpoczyna się nie po to, by stracić, lecz po to, by zyskać. Jak to zrobić skutecznie, wiedzą bohaterowie tej książki, założyciele i prezesi jedenastu polskich firm, którym udało się dokonać międzynarodowej ekspansji na szeroką skalę. Krzysztof Rybiński przedstawia tu historie ich drogi do sukcesu, zmagania z przeciwnościami gospodarczymi i proceduralnymi czy problemami finansowymi, sposoby przezwyciężania nieufności i różnic kulturowych, i wreszcie skuteczne, wypracowane przez lata metody na podbicie zagranicznych rynków zbytu. Zapoznanie się z tymi wywiadami pozwoli polskim firmom ograniczyć koszty ekspansji międzynarodowej, uniknąć kłopotów i odnieść sukces. Ta książka to także hołd oddany polskiej przedsiębiorczości i jej reprezentantom, którzy - choć zaczynali działalność lokalnie - potrafili myśleć globalnie i patrzeć poza granice naszego kraju. Prof. Krzysztof Rybiński - jeden z najbardziej znanych polskich ekonomistów. Karierę zawodową rozpoczynał jako informatyk w Japonii, potem był głównym ekonomistą kilku banków, wiceprezesem NBP, gdzie pod jego nadzorem zmieniono sposób inwestowania rezerw dewizowych, dzięki czemu Polska w ciągu dwóch lat zarobiła dodatkowo miliard dolarów. Był członkiem Komisji Nadzoru Finansowego, partnerem w globalnej firmie doradczej i członkiem wielu rad nadzorczych. Obecnie jest rektorem Akademii Finansów i Biznesu Vistula, w której studiuje 5000 studentów z 40 krajów. Prowadzi też własną firmę doradczą. W 2012 roku został wybrany przez polskich przedsiębiorców najczęściej słuchanym przez nich ekonomistą.

Język Go, zwany także golangiem, został opracowany w firmie Google i zaprezentowany światu w 2009 roku. Zaprojektowano go pod kątem wydajności przetwarzania sieciowego i wieloprocesorowego. Autorzy chcieli, aby łączył łatwość pisania aplikacji z wydajnością języków kompilowanych. Podobnie jak JavaScript czy Python, Go jest językiem, który można szybko zrozumieć, a dzięki temu bezzwłocznie zacząć tworzyć funkcjonalny kod. Niemniej, aby zyskać uznanie potencjalnego pracodawcy i swojego nowego zespołu, poza wiedzą o składni i instrukcjach sterujących oraz praktyczną umiejętnością kodowania trzeba poznać określone konwencje i techniki. Ta książka, podobnie jak inne pozycje serii Rusz głową!, została przygotowana zgodnie z najnowszymi odkryciami nauk poznawczych, teorii uczenia się i neurofizjologii. Oznacza to tyle, że dzięki niej będziesz się uczyć zgodnie z zasadami pracy swojego mózgu: zaangażujesz umysł, wykorzystasz wiele zmysłów i niepostrzeżenie przyswoisz język programowania Go. Innymi słowy: w naturalny sposób zaczniesz programować! Niecodzienny wygląd i struktura książki sprawiają, że zamiast klasycznego podręcznika otrzymujesz polisensoryczne doświadczenie poznawcze, zaprojektowane tak, aby uzyskać umiejętności przydatne każdemu deweloperowi! Nawet jeśli musisz posługiwać się innymi językami programowania, dzięki tej pozycji nauczysz się technik i praktyk, które będziesz stale wykorzystywać podczas kodowania! W tej książce między innymi: solidne podstawy tworzenia kodu, który będzie przejrzysty i łatwy w utrzymaniu metody, funkcje, pakiety... testowanie kodu i obsługa błędów dynamiczne aplikacje internetowe szablony HTML Go: rusz głową i programuj!
