Moving from Redis to Valkey
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.
Server Hardening
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.
New server: Install & configuration of services (Part III)
Welcome back, this will be the 3rd 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.
New server: Setup Linux (Part II)
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.
New Server: Buy & Assemble (Part I)
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.
GPT-3 – We are doomed
I would like to talk about artificial intelligence (AI), GPT-3 to be specific. Has been a while since I posted an article, but I noticed an urge to write about GPT-3 🙂. Without further ado, let’s get into what GPT-3 is. And why this is such an important topic to discuss.

Get the most out of your network
Lately I moved to my new home. My idea was to setup a good stable and high performance LAN network within my home. This project sounds pretty easy at first, but it was harder than I initially suspected it to be.
In this article I talk about my goals for this project. The list of materials to get you started and creating your own network. I will talk about some useful unix tools for network analysis. How-to setup your own NFS (Network File System) server. Last but not least, I will give some Linux network tweaking advise and share my future plans.
RollerCoaster Tycoon 2 – Cross-platform
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.
Why should you upgrade to PHP7?

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.
Debian 8 Jessie Server handleiding

Niet lang geleden heb ik mijn server opnieuw opgezet. Ik maak gebruik van Debian 8 (Jessie) als Linux distributie, en heb veel verschillende services geïnstalleerd en geconfigureerd (waaronder een mail server, webmail, cloud storage en git). Gelukkig hield ik alles netjes bij in een logboek. Ik zou graag mijn stappen willen delen, zodat iedereen een eigen server kan opzetten.
Ik ga ervan uit dat je beschikt over enige basis kennis van GNU/Linux (Debian). Ook al beschik je niet tot nauwelijks over deze kennis, zou het toch mogelijk moeten zijn om deze handleiding stap voor stap te volgen.
SSH tunneling: interne/externe poort doorsturing

SSH (Secure-shell) wordt gebruikt om remote in te loggen in een server of computer. Maar wist je dat je nog veel meer met SSH kunt doen? Naast remote inloggen, bied SSH ook ondersteuning voor het doorsturen van TCP poorten (tunnel), X11 verbindingen om je beeld door te sturen en tot slot bestandsoverdracht (wat via SFTP of SCP gaat).
We houden het in dit artikel bij het doorsturen van poorten, ook wel SSHÂ tunneling genoemd.
Wat is SSH tunneling? En wat kun je er allemaal mee doen?
Het grootste beveiligingslek in de geschiedenis – Heartbleed Bug

Afgelopen weken stond het internet er vol mee: de OpenSSL Hearbleed Bug.
Maar wat is precies het probleem? En waarom eigenlijk? Wat zijn de gevolgen en hoe heeft het ooit kunnen ontstaan?
Het roept veel vragen op, ik geef je in dit artikel meer duidelijkheid over de Heartbleed bug. Lees snel verder en kom te weten hoe ons internet beveiligd is en wat de Heartbleed bug betekent voor ons allen.
