GNU/Linux Rapid Embedded Programming. Your one-stop solution to embedded programming on GNU/Linux
Rodolfo Giometti
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: Building Web Applications. Building Web Applications
Nathan Kozyra, Mat Ryer
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. It is a statically typed language with syntax loosely derived from that of C, adding garbage collection, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library.This course starts with a walkthrough of the topics most critical to anyone building a new web application. Whether it’s keeping your application secure, connecting to your database, enabling token-based authentication, or utilizing logic-less templates, this course has you covered. Scale, performance, and high availability lie at the heart of the projects, and the lessons learned throughout this course will arm you with everything you need to build world-class solutions. It will also take you through the history of concurrency, how Go utilizes it, how Go differs from other languages, and the features and structures of Go's concurrency core. It will make you feel comfortable designing a safe, data-consistent, and high-performance concurrent application in Go.This course is an invaluable resource to help you understand Go's powerful features to build simple, reliable, secure, and efficient web applications.
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.

As you advance through the chapters, you'll explore how to automate the cloud using software development kits (SDKs), extend HashiCorp's Terraform and Packer using Go, develop your own DevOps services with gRPC and REST, design system agents, and build robust workflow systems.By the end of this Go for DevOps book, you'll understand how to apply development principles to automate operations and provide operational insights using Go, which will allow you to react quickly to resolve system failures before your customers realize something has gone wrong.
Go global! Wywiady z twórcami polskich firm, które zdobyły rynki międzynarodowe
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. Regularnie występuje w telewizji, pisuje felietony do krajowych dzienników i tygodników, jego artykuły ukazują się też w „Financial Times”. Patroni medialni:
