This repository is primarily a curated knowledge base and personal reference collection (a 'second brain') organized into dozens of markdown files across categories such as coding languages, blockchain, operating systems, trading, and general utilities. Each markdown file contains tables of contents and extensive lists of external links to tools, libraries, tutorials, and best practices. The repository also includes a small set of utility scripts (e.g., remark.js for auto-generating table of contents, wip-dedupe.js for deduplication, shell migration scripts, and code snippets) and an Obsidian vault configuration. While not a traditional application, the automation scripts add a thin layer of tooling around the curated content. The primary value is as a discovery index for developers and researchers, but the code itself is minimal and tightly coupled to personal workflow, limiting reuse.
