  • Tesseract.js

    What do you have against tesseract.js?

  • walt

    :zap: Walt is a JavaScript-like syntax for WebAssembly text format :zap:

    • Project mention: Guile Hoot v0.1.0 Released | news.ycombinator.com | 2023-10-16

    This is so cool!

    > Self-contained toolchain: No emscripten, binaryen, wabt, etc.

    Tangent: I am sincerely surprised by how few languages seem to do this. I know of Walt and... that's it (although I am sure there are more). I'd expect there to be more experimental small languages targeting WASM directly at least.

You can try out the benchmark https://rhashimoto.github.io/wa-sqlite/demo/benchmarks.html.

    And the other contestant is Dexie, stable https://dexie.org/.

    If you were to branch into a new venture today, which one would you pick? And why?

  • camaro

    • Project mention: Using XPath in 2023 | news.ycombinator.com | 2023-07-16

    back in the day where every OTA (online travel agent) and airlines use XML for their API, we had to integrate them in an API gateway where to unify their API schema and workflow.

    we wrote a small package[1] (using pugixml) to transform XML to JSON using a custom Xpath template syntax. Make our job much easier.

  • wasmedge-quickjs

    • Project mention: Spin 2.0 – open-source tool for building and running WASM apps | news.ycombinator.com | 2023-11-04

    I'm impressed you're already leveraging the component model. I thought it wasn't quite ready for primetime yet, but it seems you're proving that wrong... I'll have to dig in more here, as I'm working embedding WebAssembly in a high performance storage engine.

    Thanks for the notes! I hear you on QuickJS - I've seen approaches of folks trying to build more node compatibility on top of quickjs (ala https://github.com/second-state/wasmedge-quickjs), but have recently heard about spidermonkey in wasmtime. Do you have intuition for nodejs vs browser in terms of what people want in terms of compatibility?
