wtf is book?

This repository is a personal collection of study notes from a developer who goes by the handle qyuhen. The title and description are in Chinese and translate roughly to "learning notes." The README is intentionally sparse: it is dated February 2023 and contains four links pointing to externally hosted documents, along with a note about a community the author runs. The four linked documents are programming books or in-depth notes covering Rust, Go, C, and NASM. NASM is an assembly language for x86 processors, so the set spans from a high-level systems language like Go down to low-level machine instruction code. All four documents are hosted on Yuque, a Chinese knowledge management and documentation platform similar to Notion, rather than stored directly in this repository. The author also mentions a community called a Knowledge Planet, which is a subscription-based knowledge-sharing service popular in China. Members of that community receive additional related content from the author. A QR code image in the README links to the community, which is named Rain Trace Learning Hall (雨痕学堂). This repository contains no code, no build files, and no runnable content. Its only purpose is to act as a public-facing index page pointing readers toward the four sets of notes on Yuque. The notes themselves are the actual content. Someone who reads Chinese and wants detailed learning materials on Rust, Go, C, or assembly programming in a Chinese-language context would follow the links here to reach the documents. The repository has no stated license and no contributors listed beyond the original author.
