Relational Database Vs NoSQL
rdbms versus nosql
It's funny the image generated by the AI, the young guy for NoSQL

As a developer, you will most likely have done a project, and had to use a relational database. It happens all the time on each project. I think I miss very few relational DBMS (Database Management System) that I haven’t used in my profile as DevOp. This has not been the case for non-relational BBDD or also called NoSQL (Not Only SQL) such as MongoDB. I will explain the differences above and in a future article, we will see their use.

VGA 666 GPIO Connector

Recently I got a AOC Model 7Vlr 17" Monitor with VGA connector and I wanted to use it with my Raspberry Pi... The real reason is that I don't have any laptop, PC or device at home with VGA output right now 😅.

Updated

This post was updated on June 23, 2024.

The best part that you are reading my blog is that I don't need to convince you with tons of resources like a dirty trickster to follow me. The resources I share with you are the best roadmaps for programming languages I found, now in 2024. Those are my personal preferences, and here are not all the language programming, only the ones I'm interested in according to my career, but I'm sure you will find them useful.

SpotX Bash script to block ads on Sp0tify

I own a license of Adguard on macOS and I'm happy with it. It blocks ads on the $potify desktop client, but I don't know what's wrong lately: It doesn't work anymore. So I found a better approach to block ads on $potify. It's a simple solution that works on both Linux and macOS.

Do you know what USB device is it? Me neither.

I'm moving from my attic to the basement, and I needed to connect my Mac to the router, because the WiFi connection is terrible. I have a USB Ethernet device that I used with a miniPC, but it was not recognized by my macOS. I found a way to install it, and I want to share it with you.
