just published a beginner-friendly, hands-on guide to GPU programming with CUDA aimed at folks who are comfortable with basic programming but new to parallel computing. Instead of throwing API references and jargon at you, this guide takes you through the why and how of CUDA step by step. It starts from first principles and builds up to real, runnable code. The goal is to make CUDA intuitive. you’ll walk away understanding how your GPU executes work and how to write code that actually runs fast.
