System Design 101
Beautiful, popular, and among the most restrictive here
What it is
Visual explainers of system-design concepts — APIs, databases, caching, distributed patterns — with real-world case studies, aimed at interview prep, from the ByteByteGo newsletter team.
Why it's interesting
Gorgeous and widely shared, but licensed CC BY-NC-ND: no commercial use and no derivatives. Despite the open-repo optics it's among the most restrictive licenses in this catalog, and it doubles as marketing for a paid newsletter.
Use cases
- Interview preparation
- A visual reference for architecture concepts
Who it's for
Engineers prepping interviews; juniors building mental models
Setup
Trivial. Read it in a browser
Limitations & cautions
You can't remix, translate, or reuse it commercially without permission, and the depth is intentionally introductory.
Editorial takeaway
No-derivatives is the license clause most people never read. Here it means you may look, but you may not build on it.
