a sneak peek at how we'll learn things here
"Go learn System Design," they said.
Cool. But what isit? Turns out it's mostly two things wearing a trench coat — Low-Level Design (how you structure code, OOP, clean architecture) and High-Level Design (how systems talk to each other at scale: load balancers, caching, databases).
Here's the fun part: back in 1994, four guys — nicknamed the "Gang of Four"— wrote a book with 23 design principles. Google didn't exist yet. Facebook didn't exist yet. And three decades later, senior engineers at those very companies still lean on ideas from that book.
That's not trivia. That's the point — good engineering ideas are timeless. Once you know why they exist, you stop memorizing and start understanding.
