Compiling to WASM with llvm on macOS
— [howto-wasm-minimal](https://github.com/ern0/howto-wasm-minimal) by Zalka Ernő ([my fork here](https://github.com/simonw/howto-wasm-minimal)) is a neat demo of a minimal WASM module. It uses C++ to define functions for simple image manipulation including blurring an image, compiles it to WASM using llvm/clang++, then uses JavaScript to run those functions against an image loaded into a `<canvas>` element.
TIL

TIL
Using the GitHub Actions cache with npx and no package.json
— Some of my repositories have GitHub Actions workflows that execute commands using `npx`, for example my [graphql-scraper](https://github.com/simonw/graphql-scraper) repo using `npx` to [install and run](https://github.com/simonw/help-scraper/blob/54ef9b1fa579dc2d3f68055ffdac9996fd6dae9c/.github/workflows/scrape.yml#L76-L80) the `get-graphql-schema` tool:

Counting SQLite virtual machine operations
