Ansible is an open source configuration, deployment and provisioning tool. In this post, I will show you how to create a task for update the operating system, install packages and rotate SSH keys
Ansible is an open source configuration, deployment and provisioning tool. Invented in 2012 and battle tested at companies with very complex IT systems, it showed a scalable approach how infrastructure can be expressed as code.
It is time for a new project! For some time, I have been playing with the idea to automate my array of Linux servers and Raspberry Pi boards. In this article, I provide the motivation, explain my infrastructure and formulate the requirements. See this post as my project kick-off!
I know, you have heard this a lot: Tests are important for your application. We all know this, right? But we do not always follow best practices until we are punished for our negligence. Here is my story.

So, you setup the project with create-react-app. You have a file `App.js` and a folder `components`. You start writing your functions, adding new components day by day. And suddenly, there are 30 files in the same folder, and you are lost.
Fetching data from an external or internal API is a common use case for web applications. With react functional components, there are different hooks to fetch data. This post explains these hooks, and helps you to understand when to use them.
A custom hook is a React functional component which exports props where at least one prop is prefixed with the keyword `use`. The `use` prop acts like a constructor: It defines the initial value that the functional component needs. Other props can be functions or state values of your hook - you decide what you want to expose.
Hooks help you a lot because they allow you to write components exactly with the lifecycle methods that you need. Hooks also give your code a declarative layout, and yes, you will also type less. This article will help you to understand functional components and hooks and see which hooks you can use in your projects.
