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!

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.

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.

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.

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.

I was searching for a good and free TLS certificate which is signed by a trusted Certificate Authority (CA). A CA is an organization for issuing digital certificates. You need to have a Certificate Authority when you want to use HTTPS, secure HTTP web server connections. You know; when you visit a secure web-page (https://) and you will see a green lock-icon in your web-browser. This icon indicates that you have an encrypted connection with this website.

In this article I will explain how TLS certification requests normally works and how Let’s Encrypt works. Let’s Encrypt is a Certificate Authority, who provides free and trusted domain certificates. Eventually, I explain how to setup Let’s Encrypt yourself using Nginx webserver.

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.

I always like to debate and dream about new technologies and the future. Which is sometimes  sci-fi, but most of the sci-fi becomes reality. I would like to share some of my (crazy?) predictions and technologies I think become truth and fully accepted within several years from now.

Ik had per ongelijk de Netgear router gebrickt, of in ieder geval de router startte niet meer goed op. Als een apparaat (router, smartphone, game console) bricked is, betekend dat hij niet goed geconfigureerd is, corrupte firmware of een hardware problemen heeft.

Waardoor het betreffende apparaat niet meer goed kan functioneren. En daardoor zou de router enkel nog bruikbaar zijn als jawel een &“brick” (=baksteen). Oopsy!

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.

Ik ben bezig met het opzetten van een eigen weerstation. Tijdens het opzetten kwam ik er achter, dat je een grote hoeveelheden data wilt opslaan (temperatuur, luchtvochtigheid, wind-snelheid, en meer…) en dat elke 10 seconden opnieuw. In dit artikel ga ik Cassandra gebruiken en leg ik uit waarom het efficiënter is vergeleken met MySQL of andere relationele databases.
