I implemented a non-prod version of SystemJS transpilation based on oxc!

Please note that this repository is still highly experimental and not fully implemented, nor does it align with Babel, but it creates a framework for further implementation here.

Wrote a command-line TOTP app for fun (actually nearly all vibe coding...), and now it can complete all local tasks related to TOTP config/generation, and it now supports Cloudflare KV to sync and load your data!

I'll be in Hong Kong for two days since tomorrow afternoon. Is anyone available to meet with me on June 7 in the afternoon and evening?

I had an idea to maintain a YouTube channel so that I can share my ideas and crafts with the public. However, I am concerned that I may be too conservative when facing the camera and speaking...

One year of toolchain-level rust, one year of abstract machine learning. Vibe coding is far from me.

No punchline.
No reversal.
Just a silence so sharp it almost felt scripted.

This is the April Fool's Day in 2025.

Just tried to create a library that uses Tikz to plot these experiment instruments, so that it can make procedures of substance clearly.

Maintaining a balance is difficult, including the ambition to study abroad, develop romantic relationships, enhance programming skills, and sustain school grades.

Winter vacation eventually came, even though it only lasted 11 days...

Conducted my first English proficiency exam in my life.

I hope I will get a certificate of 140+.

My 2024 summary graph from GitHub:

Curious about why there are 9,477 stars? 🤔

I believe 2024 is a significant milestone for me in development – active community engagement 🙋‍♂️, better relationships 🫣, deeper mastery of JS/TS, Python, and Rust 👨‍💻, and ambitious goals for the future 💯.

I came up enhancing an obsessive idea: chasing after admission to the institute that produced the world's most common open source license.
I hope I can achieve it next year.

My demo can transform the syntax of simple JavaScript code to Python now! Thanks to the toolchain from @boshen.github.io for JavaScript (oxc), and astral.sh for Python (ruff).
The next step is to replace std methods, like replacing the `console.log` with `print` in the picture.

I clicked on the HMMT's online individual tournament by mistake and forced myself to sleep to do a couple of "from mid-AMC to upper-AIME" level problems... Now my brain is filled with stars and distortions.

Came up with an idea of writing a universal code translator for fun and portfolios last week.

It is mainly conducted by IRs to be the bridge, including the LLIR (Low Level) which is AST-like but generic; HLIR (High Level) which represents block behavior like error handling, etc.

Any suggestions?

Hello all! My former 🦋 account was on my own data server, but the server is expired and suspended since I forgot to extend it (sad). Here is my new account! The handle is still the original one!
