With the help of Go for DevOps, you'll learn how to deliver services with ease and safety, becoming a better DevOps engineer in the process.Some of the key things this book will teach you are how to write Go software to automate configuration management, update remote machines, author custom automation in GitHub Actions, and interact with Kubernetes. 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:

Go Systems Programming. Master Linux and Unix system level programming with Go
Mihalis Tsoukalos
Go is the new systems programming language for Linux and Unix systems. It is also the language in which some of the most prominent cloud-level systems have been written, such as Docker. Where C programmers used to rule, Go programmers are in demand to write highly optimized systems programming code.Created by some of the original designers of C and Unix, Go expands the systems programmers toolkit and adds a mature, clear programming language. Traditional system applications become easier to write since pointers are not relevant and garbage collection has taken away the most problematic area for low-level systems code: memory management.This book opens up the world of high-performance Unix system applications to the beginning Go programmer. It does not get stuck on single systems or even system types, but tries to expand the original teachings from Unix system level programming to all types of servers, the cloud, and the web.
