New Video on YouTube:Negative Numbers in Binary: The Trick That Powers Every Computer !
What happens when a computer encounters -1? The answer is weirder — and more elegant — than you'd expect.

In this video we dig into how computers actually represent negative numbers in binary. We start with the
obvious-but-broken approach (sign-magnitude), show why it fails, then work through one's complement
and arrive at two's complement — the system that quietly powers every processor you've ever used.

Covered in this video:
→ Why you can't just slap a minus sign on a binary number
→ Sign-magnitude: the intuitive approach and its inherent flaw
→ One's complement: almost there, but not quite
→ Two's complement: the elegant solution and why it works

New Video on YouTube:How to activate Davinci Resolve Studio in Linux !
If you can't activate Davinci Resolve Studio in Linux, and you get an error after typing in your licence key, there is nothing wrong with the key. What you have to do is change the ownership of /opt/resolve to be owned by the user running Davinci Resolve. Then try to activate it again.

New Video on YouTube:From Triangles to Pixels - the magic behind 3D graphics !
Support the channel, visit patreon.com/ncot_tech

Every frame of a 3D game you've ever seen ultimately reduces to pixels written into memory. No matter how fast the GPU or how impressive the graphics, it all comes down to plotting pixels on the screen.
Today we're taking a short look at how triangles get turned into pixels. It seems easy enough, but this is something early software 3D had to do by hand, and something modern GPUs are doing all the time.

New Video on YouTube:Neon Horizons: Building a Vapourwave 3D World in OpenGL (C++) !
Support the channel, visit patreon.com/ncot_tech

In this video I build a classic vapourwave scene from scratch using C++ and raw OpenGL. No game engines, no shortcuts—just direct graphics programming. The scene features the iconic retro grid floor, distant mountains, and a glowing neon sunset sky inspired by 80s aesthetics.

I walk through the full process of how the scene works, including the C++ code structure, how the shaders create the vapourwave look, and how the geometry is rendered using OpenGL. Along the way I also show some of the mistakes and debugging steps that happened during development, which helps illustrate how real graphics programming problems get solved.

New Video on YouTube:Re-discovering 3D Graphics the Way Early Games Did !
This video is my journey through learning how early games drew 3D graphics before 3D APIs and modern GPUs existed. In fact, before old 3D APIs like OpenGL and old GPUs existed, too.

Just me, the computer and some code and maths. No 3D hardware or 3D libraries were used in the making of this video.

New Video on YouTube:Retro Gamedev is Hard !
Welcome to the next edition of Gamedev The Hard Way, my attempt at writing a game from scratch for the Agon Light, using nothing but C. This time I create a tilemap system.

The tilemap system is able to load tiles drawn in Aseprite, load a tile map drawn in Tiled, and scroll around a world that's larger than the screen.

I also develop an Aseprite plugin for exporting image data, and a Tiled plugin to export map data.

Welcome to the next edition of Gamedev The Hard Way, my attempt at writing a game from scratch for the Agon Light, using nothing but C. This time I make a joystick work by building a joystick interface for the Agon Light. Then I program it to add it to my game.

New Video on YouTube:Axis-Aligned Bounding Boxes - Collision Detection without physics !
Welcome to the next edition of Gamedev The Hard Way, my attempt at writing a game from scratch for the Agon Light, using nothing but C. This time I get thoroughly distracted and accidentally make a Pong style game idea while figuring out how to add collision detection to my game engine. I implement the AABB Axis Aligned Bounding Box algorithm.
