Notes of the book System Desgin Interview - An Insider's Guide

Save to My finds to follow releases and star growth. Saved in this browser.

About the project

Notes from Alex Xu's System Design Interview books (Vol 1 and 2), covering 28 classic system design problems — from rate limiters and key-value stores to YouTube, Google Drive, and a stock exchange. For interview preparation and studying distributed system architecture.

Useful for
  • Prepare for a system design interview by reviewing common design problems
  • Study distributed system design approaches through concrete case studies
  • Use the notes as an architecture cheat sheet when designing a service

4.1 Breakout Magnitude out of 10 — how fast interest is growing, not a quality score.

Star growth looks organic. Data as of October 8, 2026, 11:14 UTC.

The star-growth assessment does not verify whether the project is safe to run.

Stars per day

07501,500July 11, 2026October 8, 2026

Bars show daily stars; the line is a moving average of the available history. Short histories do not yet establish a reliable usual pace. Red marks spike days.

Why it’s trending

  • There are not enough fresh counter measurements for today's UTC day. The gain is unknown.
  • Over the last two days the pace is 1.9× that of the previous week and a half.
  • GitHub Trending today: #9, +398 stars.
  • About 26 forks a day — people are taking the code.

Three GitHub discoveries in each edition

What they do, why they are gaining interest, and what to check before using them.

Star trust

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.

These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
