This repository is a personal study record for UC Berkeley's CS61A (Structure and Interpretation of Computer Programs) course, completed in 2024. It contains the author's solutions to homework assignments (hw01–10), lab exercises (lab00–12), and four major projects: Hog (dice game), Cats (typing tutor), Ants (tower defense web game), and a Scheme interpreter. The codebase is hybrid in nature: it is primarily an educational portfolio, but it includes several functional application components such as a web-based Scheme editor with interactive visualizations (environment diagrams, substitution trees, turtle graphics), a Flask-based multiplayer typing test, and a real-time web game (Ants) with vendored dependencies (Flask, SocketIO, Werkzeug). The repository also contains a complete Scheme interpreter (parser, evaluator, REPL) and a SQL lab. The code is functional and demonstrates understanding of core CS concepts, but it suffers from massive duplication of editor assets (Ace editor, static files) across multiple assignment directories, vendored third-party libraries that are not centrally managed, and a lack of modularization. It is not intended for production use or external reuse, but the Scheme editor framework and the ucb.py utility module exhibit patterns that could be extracted for educational tooling.
This repository provides a Chinese localization (汉化) of Clash for Windows, a popular proxy client. It contains modified app.asar files (renderer.js and main.js) with translated UI strings, build scripts for packaging the modified Electron app, and installers. The core functionality is string replacement via regex-based translation tables. The repo also includes the original Clash core binaries and static assets. It is not a standalone software project but a patch set; the code quality is functional but unremarkable, with boilerplate build scripts and tightly coupled modifications. The primary value is the translation effort, not software craftsmanship.
