Field notes

The catalog divides material into Computing, Graphics & games, Science, and Music, with difficulty filters and lesson counts for individual tracks. Examples range from NASM x86-64 assembly, including live CPU stepping, to Vulkan 1.3 setup and mathematics worked by hand; the pendulum demo exposes a length control and updates its period formula. The homepage identifies Gabriel Carvalho as author and offers English, Portuguese, Spanish, and Chinese controls.
