Small, Sharp Software ToolsThe command-line interface is making a comeback. That's because developers know that all the best features of your operating system are hidden behind a user interface designed to help average people use the computer. But you're not the average user, and the CLI is the most efficient way to get work done fast. Turn tedious chores into quick tasks: read and write files, manage complex directory hierarchies, perform network diagnostics, download files, work with APIs, and combine individual programs to create your own workflows. Put down that mouse, open the CLI, and take control of your software development environment.
No matter what language or platform you're using, you can use the CLI to create projects, run servers, and manage files. You can even create new tools that fit right in with grep, sed, awk, and xargs. You'll work with the Bash shell and the most common command-line utilities available on macOS, Windows 10, and many flavors of Linux.
Create files without opening a te ...

Beginning Kubernetes on the Google Cloud PlatformUse this beginner's guide to understand and work with Kubernetes on the Google Cloud Platform and go from single monolithic Pods (the smallest unit deployed and managed by Kubernetes) all the way up to distributed, fault-tolerant stateful backing stores.
You need only a familiarity with Linux, Bash, and Python to successfully use this book. Proficiency in Docker or cloud technology is not required. You will follow a learn-by-doing approach, running small experiments and observing the effects.
Google open sourced Kubernetes in 2015 and now it is the industry standard in container orchestration. It has been adopted by all leading vendors of cloud, on-prem, and hybrid infrastructure services: Microsoft (Azure AKS), Amazon (AWS EKS), IBM (IBM Cloud Kubernetes Services), Alibaba Cloud (ACK), RedHat (OpenShift), and Pivotal (PKS). Even though Kubernetes is offered by all of the market-leading cloud providers, the Google Cloud Platform (GCP) offers an integrated shell (Google Cloud Shell) ...

Exploring BlazorBuild and develop web applications with Blazor in C#. This book will cover all three types of Blazor – server-side, client-side, and hosted along with other features of the technology. You'll see that Blazor is a web UI framework based on C#, Razor, and HTML and how it runs front-end logic using C# either on the server or on the browser using WebAssembly.
The author starts by introducing WebAssembly and gives an overview of Blazor along with its various categories. Next, you'll get started with Blazor where you learn the basics, including Razor syntax implementation. Here you will go over the major differences between Blazor and Razor and how the syntax works. A demo of the layout and navigation for server-side Blazor is followed by usage of Razor syntax to control an application in client-side Blazor. Further, you will go through the project layout, navigation, and routes for the API. Here, you will understand how to access the API from the front end and use the shared library fo ...
