Linux systemadministration från grunden lär dig allt du behöver för att komma igång att administrera Linuxdatorer, vare sig det är servrar på internet eller bärbara datorer. Eller varför inte en Raspberry Pi för mätningar? Linux är viktigare och större än någonsin. Det finns överallt. På servrarna som tillhandahåller många av de webbsidor du surfar på. Det finns i stora beräkningskluster, telefoner, bilar och underhållningssystem. I början av boken får du grundläggande kunskaper om hur du arbetar med Linux. Här lär du dig bland annat hur Linux är uppbyggt, användbara kommandon, filsystemets uppbyggnad och hur du redigerar filer i både Nano och Vi. Därefter lär du dig att skapa nya användare och grupper i systemet. Du lär dig också hur du sätter filrättigheter i Linux. Mot mitten av boken lär du dig mer avancerade ämnen, så som textbearbetning, att skriva egna skalskript, administrera tjänster, processhantering, nätverkskonfiguration och mycket mer. Boken fungerar för de flesta Linuxutgåvor. Men bland annat kapitlen om pakethantering och nätverkskonfiguration har skrivits speciellt för Red Hat, CentOS, Fedora, Debian och Ubuntu. Till varje kapitel finns det övningsuppgifter så att du själv kan träna på det du lärt dig. En del av övningsuppgifterna går utanför boken, och du måste då själv leta upp rätt kommandon i den inbyggda manualen.

Designed for busy IT professionals, this innovative guide will take you from the basics to PowerShell proficiency through 25 tutorials you can do in your lunch break.

about the technologyThe PowerShell scripting language and administrative shell was initially created for Windows, providing a high-quality command-line interface and awesome automation features. As part of Microsoft's ongoing strategy to support non-Windows platforms with its Azure cloud service and .NET Core framework, PowerShell now runs on Linux and macOS. Like Bash, PowerShell can execute and script nearly any aspect of Linux, so you can easily manage repetitive daily tasks, servers, Cloud resources, Continuous Integration pipelines, and more. Because PowerShell is a full-featured programming language, however, it provides capability well beyond traditional shell scripting languages, such as the ability to treat OS components as objects.

about the bookLearn PowerShell in a Month of Lunches: Covers Windows, Linux, and macOS is a user-friendly tutorial to managing Linux and macOS systems with PowerShell. It's based on the bestselling Learn Windows PowerShell in a Month of Lunches, which has introduced PowerShell to nearly 100,000 readers. You'll learn how PowerShell shapes up to Bash or Python scripting as you write and run simple scripts that automate boring daily tasks. As you progress through the book, you'll use PowerShell to write Continuous Integration Pipelines and manage cloud-based servers. Just set aside one hour a day for a month, and you'll be automating tasks faster than you ever thought possible!

what's inside- Why you should use PowerShell on Linux and macOS- Background jobs and automation techniques- Simple scripting to automate repetitive daily tasks- Common syntax and commands cheat sheet- Each lesson takes you an hour or less

about the readerFor IT professionals comfortable administering Windows or Linux. No previous experience with PowerShell or Bash required.

about the authorTravis Plunk has been a Software Engineer on various PowerShell teams since 2013, and at Microsoft since 1999. He was involved in open sourcing PowerShell and has worked on the project full time since shortly after the project was announced.

James Petty is a Microsoft MVP, and the CEO and Executive Director for the DevOps Collective and PowerShell.org.

Tyler Leonhardt has been a Software Engineer on the PowerShell team since 2017, and at Microsoft since 2016. He is a core maintainer of the PowerShell extension for Visual Studio Code.

Discover how to apply software engineering patterns to develop more robust firmware faster than traditional embedded development approaches. In the authors’ experience, traditional embedded software projects tend towards monolithic applications that are optimized for their target hardware platforms. This leads to software that is fragile in terms of extensibility and difficult to test without fully integrated software and hardware. Patterns in the Machine focuses on creating loosely coupled implementations that embrace both change and testability.This book illustrates how implementing continuous integration, automated unit testing, platform-independent code, and other best practices that are not typically implemented in the embedded systems world is not just feasible but also practical for today’s embedded projects.After reading this book, you will have a better idea of how to structure your embedded software projects. You will recognize that while writing unit tests, creating simulators, and implementing continuous integration requires time and effort up front, you will be amply rewarded at the end of the project in terms of quality, adaptability, and maintainability of your code. What You Will LearnIncorporate automated unit testing into an embedded projectDesign and build functional simulators for an embedded projectWrite production-quality software when hardware is not availableUse the Data Model architectural pattern to create a highly decoupled design and implementationUnderstand the importance of defining the software architecture before implementation starts and how to do itDiscover why documentation is essential for an embedded projectUse finite state machines in embedded projectsWho This Book Is ForMid-level or higher embedded systems (firmware) developers, technical leads, software architects, and development managers.

Visual Thinking brings the science of perception to the art of design. Designers increasingly need to present information in ways that aid their audience's thinking process. Fortunately, results from the relatively new science of human visual perception provide valuable guidance.

In this book, Colin Ware takes what we now know about perception, cognition, and attention and transforms it into concrete advice that designers can directly apply. He demonstrates how designs can be considered as tools for cognition - extensions of the viewer's brain in much the same way that a hammer is an extension of the user's hand. The book includes hundreds of examples, many in the form of integrated text and full-color diagrams.

Experienced professional designers and students alike will learn how to maximize the power of the information tools they design for the people who use them.
