Rust never sleeps — and neither do haters
Show HN: I wrote a Rust book ending with a Redis clone
A cheap learn-to-code guide drops, and the comments instantly turn into a trust fight
TLDR: An author posted a budget-friendly Rust learning book that ends with readers building a mini Redis-like app from scratch. The comments quickly shifted from curiosity to suspicion, with people asking why it beats the official book, why it is not in major stores, and whether the sales pitch was written by AI.
A new Hacker News post tried to sell a simple dream: learn the Rust programming language from scratch, then finish by building your own tiny version of Redis, a popular tool for storing data fast. The pitch is very much "not just theory" — 23 chapters, around 20,000 words, all code included, and priced at less than a coffee. For anyone who has ever bounced off confusing coding books, that sounds like a neat little underdog story.
But the real fireworks were in the comments, where the community immediately split into three camps: the skeptics, the shoppers, and the sniff-test police. One person asked the brutally practical question: how is this better than the official Rust book? Ouch. Another skipped the coding debate entirely and went full customer-service mode, asking why it is not on Amazon or Apple Books like a "normal" ebook. And then came the spiciest jab of all: a commenter said the sales description itself looked written by a large language model — basically accusing the whole thing of having AI vibes before even opening the book.
That last comment is where the drama really lives. In one line, the book went from "affordable guide for beginners" to "is this real, or is this robot slop?" territory. No memes exploded in the tiny thread, but the mood was classic internet: one person wants value, one wants convenience, and one is already holding a lie detector up to the blurb.
Key Points
- •The article presents *Zero to Rust*, a 23-chapter Rust book focused on practical systems programming.
- •The book is structured in six parts covering fundamentals, modelling, robust code, systems programming, project architecture, and a capstone project.
- •Core topics listed include ownership, borrowing, lifetimes, structs, enums, traits, generics, error handling, iterators, smart pointers, concurrency, async Rust, macros, modules, and testing.
- •The capstone project is a concurrent Redis-like key-value store built from scratch with a TCP server, shared state, expiry handling, disk persistence, CLI client, and test suite.
- •The book is aimed at engineers transitioning from Java, Python, or C++, as well as ambitious beginners, and is described as roughly 20,000 words with all code examples included.
