BASICS + TRENDING TECHNOLOGIES

AI & ML

Local LLMs, RAG, and the engineering underneath them.

Every topic here has three levels — Introduction, Intermediate, and Advanced — so pick one and go as deep as you want.

How LLMs Work
Token-by-token prediction — from a first-principles intro to production internals.
Introduction Intermediate Advanced
Prompt Engineering
Why the same question can get a vague or a sharp answer — and the techniques that decide which.
Introduction Intermediate Advanced
Context Window
The model’s working memory — what it is, why it fills up, and what gets forgotten first.
Introduction Intermediate Advanced
Context Engineering
Why what the model knows matters more than how you ask it — and how that’s different from prompt engineering.
