Publishing WASM Wheels to PyPI for Use with Pyodide
Simon Willison's Weblog12 hours agoTutorialPyodide 314.0 removes a long-standing distribution bottleneck by allowing WebAssembly-compiled Python wheels to be published directly to PyPI, so any package author can now distribute Pyodide-compatible packages without Pyodide team involvement. Previously, the team manually built and hosted over 300 packages. Simon Willison celebrated by publishing luau-wasm — a Lua-based scripting language compiled to WASM — using Codex with GPT-5.5 to automate the packaging workflow.

Simon Willison's Weblog12 days agoReleaseSimon Willison released datasette-agent-micropython 0.1a0, an alpha aimed at letting Datasette Agent generate and execute Python safely. The project focuses on sandboxing, with MicroPython and WebAssembly-related techniques suggested by the tags. Willison says the early results look promising and that GPT-5.5 has not yet escaped the sandbox, though this remains an early alpha.
