Show HN: Learning Rust by writing a Markdown to HTML compiler

Hacker News - Tue, 07/28/2026 - 9:04pm

Hi HN,

I'm new to Rust and, after half of `The Rust Programming Language` I decided to delve into a project I would actually use: a markdown to html compiler that actually serves my micro-blog (I started just right after publishing the project hehe). The project is intentionally small and one-file contained: I wanted to have the full picture in mind.

I'm open to comments, suggestions and PRs. If you asked me more convincing arguments to "why did you do it?" rather than "to learn Rust" I would respond with: LLMs are effectively a new type of web users today and will be more and more present in the future. Having a full, well formatted, .md interface of a website can make it easier for them to access the content.

OpenAI’s Rogue AI Agent Hacked More Than Just Hugging Face

In a new disclosure, OpenAI says its agent used exposed logins to gain access to at least four “publicly available services” in its unhinged quest to solve a test.

Show HN: Manim (3Blue1Brown's animation engine) in the browser via WebGPU

Hacker News - Tue, 07/28/2026 - 8:07pm

Grant Sanderson (3Blue1Brown) created Manim, the Python library he uses to make the math animations in his videos.

We reimplemented Manim with the same Python API, but the implementation underneath is Rust, connected to Python through PyO3. The Rust code uses wgpu, so rendering happens on the GPU with hardware acceleration.

To run it in the browser, we compiled the Rust parts to WebAssembly so the PyO3 extension loads in Pyodide. In the browser, wgpu targets the WebGPU API, so animations render in real time on your GPU through the browser.

The editor is Monaco (the editor that powers VS Code) with a live preview: write your Manim code on one side, watch the animation update on the other.

There's also a built-in AI agent if you'd rather vibe-code your animations.
