✍🏻 Source Code Deep Dives, System Design & Engineering Blogs | Halfrost-Field 冰霜之地：源码解析、系统设计与工程实践笔记
A bilingual collection of long-form technical articles, almost all Markdown, that explains how specific systems work internally: vLLM's V1 engine, Go's runtime and Google S2 geometry, TLS 1.3 and HTTP/2, plus older iOS and Objective-C material. It is for engineers who want source-level explanations rather than a library to install, and the Go language tag on GitHub does not reflect a codebase.
The vLLM series is pinned to one commit (v1 @ 6cf7b26bd) and follows real code paths from generate() through the scheduler to the KV cache manager, so claims can be checked against that source. The S2 series explains the algorithms behind golang/geo, such as CellID generation, De Bruijn sequences, Hilbert neighbour finding and region covering, rather than just how to call the API. The TLS 1.3 series is split into separate articles on the handshake, record layer, key computation, 0-RTT and compliance, and the HPACK article includes a worked encoding example alongside the spec.
The vLLM articles track a fast-moving project at a single commit, so they will drift, and nothing in the README says when or how they get refreshed. Much of the older material, including the Ghost blog, Vue 2.3.4, ReactiveCocoa, Cordova and PhoneGap sections, is years out of date and sits in the same tables as current work with no marking. The English articles are translations of Chinese originals, and the README does not say whether they stay in sync, so the two may diverge. Little of it is runnable: the tree is Markdown, SVG and a few PDFs, so any code lives inside prose with no tests to check it.
