This is a DNS blog series of two parts.

In this first part I will give an introduction to DNS, including some examples and hands-on experiments on the command line. So you will understand the concept of DNS much better! In Part 2 we will setup our own DNS server. Let’s get started!

This guide is focus on moving from Redis to Valkey on my Ubuntu Server 24.04. There is no official documentation on how to setup Valkey via the binary, so this guide will help you to get started with Valkey. Which in my case will replace my Redis servers.

I would like to share a nice ‘secret’. I want to introduce you to the Starship prompt! This is a getting started guide for Starship. I’m using Starship every day.

Starship Prompt, not to be confused with the Starship from SpaceX 😆, is a cross-shell prompt written in Rust. The prompt works in any common shell you may already use under GNU/Linux, like Bash.
