Big free system‑design resources
Shruti Codes shared a massive free repository covering scaling, rate limiting, hashing, URL shorteners, chat/news feeds and more — a 500+ page practical reference. Alex Xu also released all seven ByteByteGo ebooks free until May 1, including System Design Vols 1–2 and AI/ML volumes. (x.com) (x.com)
Shruti’s GitHub account (Shruti‑codes) lists 34 public repositories and maintains a GitHub Pages site for project hosting. (github.com) A pinned personal portfolio under the same handle shows recent updates and project links, indicating the author publishes multi‑page technical content from that account. (shruti-codes.github.io) ByteByteGo’s official site is running a limited‑time offer that advertises “Claim Your Free Month” and states the promotion ends on May 1. (bytebytego.com) ByteByteGo publishes downloadable Visual Guides (the site lists categories such as “Caching & Performance” with 20 guides and “AI and Machine Learning” with 47 guides) and its GitHub repository includes reference links for the Volume 1/Volume 2 book material. (bytebytego.com) ByteByteGo’s site also cites over 1,000,000 newsletter subscribers and promotes course access as part of the May 1 window, while multiple Shruti‑named repos on GitHub present system‑design notes and low‑level design practice files that can be cloned for hands‑on drills.
