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.

Bun 1.0 is out of the oven! And it’s a big deal, because there wasn’t much happening in terms of performance or innovation in the recent years with NodeJS. Sure we have Deno, but who is really using Deno? Also Bun tries to combine various tools into one tool, helping out the developers a lot.

Introduction

Security of a system is often overlooked or not considered important enough. Some might think not about the possible consequences, which might result in a hacked or compromised server. Maybe sensitive data gets stolen or encrypted with major consequences.

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.

Welcome back, this will be the 3^rd part of new server series. In the previous parts I assembled the server and prepared the machine with Ubuntu Server. I configured the basics things like; networking, RAID setup, E-Mail and more. In case you missed that: read Part I and Part II.

Today, we will finish the job with installing and configuring all the services we love so much. Again, I included a Table of Contents for convenience reasons, since it quite a long article. But hopefully the table will help you to navigate around.

Happy new year everyone! 😎 Let’s install Ubuntu Server 20.04 as part of the blog series. And continue with setting-up the software part of the server. If you missed Part I, read that first.

My current server is 15 years old, and time for an upgrade! Finally! After all, adding additional memory is not good enough and we hitting the limits of the old hardware. We will replace the whole server from the ground-up.
