  Formally Verified 3D CSG Mesh Intersection in Lean 4

  This project presents what is claimed to be the first formally verified implementation of a 3D constructive solid geometry mesh intersection kernel, built in Lean 4 and checked against a short formal specification. It is also positioned as a way to rely on machine-checked proofs rather than trusting AI-generated implementation code, with a browser demo running the verified kernel in WebAssembly.

  Teaching Kids Programming with Forth

  The article describes an instructor’s experience teaching middle and high school students programming through the Forth language rather than more common choices like Python or Scratch. It explains the curriculum choices, including a focus on stack-based thinking, limited syntax, and having students build small creative projects they can run in a browser-based learning environment.

  SQLite Query Explainer

  Simon Willison introduced SQLite Query Explainer, a browser-based tool that runs SQL queries against a SQLite database and annotates the results of both EXPLAIN QUERY PLAN and low-level EXPLAIN output with plain-English explanations. The tool runs SQLite in Python through Pyodide and WebAssembly, aiming to make query planner and virtual machine behavior easier to understand.

  Mermaid diagrams rendered as Unicode box art

  Simon Willison describes experimenting with a Rust-based terminal renderer for Mermaid diagrams found in the open-sourced Grok CLI codebase. He also prototyped running it in the browser through WebAssembly, producing a tool that displays Mermaid diagrams as Unicode box art. The post is a short developer-focused note about adapting an existing terminal component for web use.

  Firefox Browser Running in WebAssembly

  A developer demo shows the full Firefox browser, including Gecko, UI components, and the SpiderMonkey JavaScript engine, compiled to run inside WebAssembly. The project uses WISP for TCP over WebSockets and includes an experimental WASM-to-JS JIT for performance testing. The author describes it as a technical experiment and points to a lighter browser-in-browser project for practical use.

  Game Boy Emulator JITs to WebAssembly to Run Faster in Browsers

  A developer built WATaBoy, a Game Boy emulator that compiles SM83 instructions to WebAssembly instead of relying only on an interpreter. The project explores whether piggybacking on browser JIT support can outperform a native interpreter, especially in environments like iOS where direct JIT compilation is restricted. The post presents the approach as a proof of concept and performance benchmark.
