C/C++
From C to modern C++: pointers, memory and the stack and heap first, then RAII, templates, move semantics and the patterns that power performant game engines.
Tracks
Intermediate
x86-64 Assembly
x86-64 assembly from the ground up with NASM: registers and memory, mov and addressing, flags, jumps and the stack, calling conventions, then reading compiler output, floating point, SIMD and the CPU pipeline — every instruction stepped through on a live CPU.
Intermediate
OpenGL 4.6
Understand the full OpenGL pipeline: vertex buffers, shaders, textures, framebuffers, and compute shaders — through hands-on C++ code.
Intermediate
GLSL
Master GLSL types, built-in functions, SDFs, procedural noise and shader techniques — from first principles to a production-ready Shader class.
Beginner
SDL3
Build real applications with SDL3: window management, input handling, audio, and a complete 2D rendering loop using C++.
Beginner → Advanced
Game Dev
Game loops and fixed timesteps, easing and springs, randomness and Perlin noise, collision detection and the patterns behind fast game code — with interactive figures.
Beginner → Advanced
Math
Mathematics from the ground up: arithmetic, algebra, geometry, trigonometry, linear algebra and calculus, worked by hand — every formula explained, every idea interactive.
Beginner → Advanced
Algorithms
Algorithms and data structures built from scratch in C++: memory and Big-O, recursion, sorting and searching, lists, hash tables, trees, heaps and graphs — every step traced in an interactive figure.
Advanced
Vulkan
Vulkan 1.3 from an empty window to a textured 3D scene: instance and devices, swapchain, pipelines, command buffers, synchronization, memory and descriptors — the explicit GPU API, every object explained.
Beginner → Advanced
AI
Artificial intelligence from scratch in C++: data and features, regression and gradient descent, classic machine learning, neural networks and backpropagation, deep learning, reinforcement learning and game AI — every formula derived, every model trained by hand.
Beginner → Advanced
Physics
Physics from the ground up: motion, forces, energy and momentum, rotation, gravity and orbits, oscillations and waves, fluids and heat, electromagnetism and light, then analytical mechanics, relativity, quantum mechanics, particles and cosmology — every law derived, every idea simulated.

Chemistry
Chemistry from the ground up: atoms and the periodic table, bonds and molecules, moles and reactions, gases and solutions, energy and reaction rates, equilibrium, acids and bases — every formula explained, every idea interactive.

Music
Music from the ground up: sound and pitch, rhythm and meter, notes and the staff, intervals and scales, chords and harmony, keys and progressions, melody and form — every idea heard, every rule explained.
How the lessons work
Every term explained
No formula appears without saying what each letter means, where each constant comes from and why each step is allowed.
Figures you can move
Drag points, move sliders and rotate 3D scenes. The figures run in the browser, on phones too.
