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 😅.

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.

I'm going to tell you a story.

One day, at my grandmother’s house, my father brought a device that was connected to the TV. It was a ZX Spectrum 48k. After plugging it in and watching them load the cassette tapes (with a sound that was a little weird) and playing on the TV, I fell in love with this new machine. I had already seen an Atari with the Pong, but this was another level.
