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.

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.

I got a running GitLab server on my Debian Jessie server. GitLab Community Edition is an open-source git repository manager, but also supports code reviews, wiki’s, issue tracking and much more! GitLab is very similar to Github in a way, however you have full control of the server. You are running your own git server.

Normally Github will do all the system administration, upgrades and such for you. They make sure your code is safe and saved no matter what. Since I use GitLab, I need to take care of my own server. What you definitively not want is; to lose all your precious data!

I was triggered by a name ‘OpenRCT2’ on the web. I was wondering if that was a game just like 0 A.D. (an open-source re-implementation of Age of Empires). And yep it was, OpenRCT2 stands for “Open-source RollerCoaster Tycoon II”.

I was thrilled when I discovered about OpenRCT2. It’s a re-implementation of the classic hit game called RollerCoaster Tycoon 2 from Infogrames (Atari). Only in US; Rollercoast Tycoon 2 sold 940,000 copies and earned $21.6 million by August 2006.

Developers who running PHP-enabled websites such as WordPress, Drupal, Joomla, Magento or even PHP frameworks like Laravel and Symfony should know about the new major PHP version. As a developer you should think about switching to PHP7. I will talk about the how-to use it, some history, the benefits of PHP7 and finally how to get PHP7 on your system.
And uhm… what about PHP version 6?

Usage

About about 98% of the websites are still using PHP version 5.*.  PHP 5 is now more than 11 years old, so it’s time to move to PHP 7 and clean up obsolete functions. The PHP project has a list of deleted functions, which helps you porting PHP 5 to PHP 7 code. And list of removed APIs & extensions.
