  • emscripten

    Emscripten: An LLVM-to-WebAssembly Compiler

  • Project mention: Python HTTP library 'urllib3' now works in the browser | news.ycombinator.com | 2024-01-30

    Browsers limit the ability for these platforms to use raw sockets, there simply is no API for it. The best that can be done /today/ is to use WebSockets, which are not the same thing any can't be used for HTTP requests without the server expecting a WebSocket connection:

  • Project mention: Zig! Can you C? | dev.to | 2024-04-04

  • wasmer

    🚀 The leading Wasm Runtime supporting WASIX, WASI and Emscripten

  • Project mention: WebAssembly: A promising technology that is quietly being enshitified | news.ycombinator.com | 2024-05-22

    I applaud the author on how clear he made the argument.

    Note: I work at Wasmer (https://wasmer.io), a WebAssembly runtime.

  • assemblyscript

    A TypeScript-like language for WebAssembly.

  • Project mention: Borgo is a statically typed language that compiles to Go | news.ycombinator.com | 2024-04-30

    I like your take but JavaScript was literally the assembly language of the web until WASM came along. There was no other language that TypeScript could compile to.

    This train of thought lead me to discover AssemblyScript! https://www.assemblyscript.org/

  • slint

  • compose-multiplatform

    Compose Multiplatform, a modern UI framework for Kotlin that makes building performant and beautiful user interfaces easy and enjoyable.

  • Project mention: Understanding file associations in JVM apps | dev.to | 2024-01-07

    So, to add file associations, we need to be able to pass both the .properties file and the --file-associations option. At the time of writing this article, the org.jetbrains.compose plugin doesn't provide such a mechanism. There is an open issue on GitHub that describes a possible workaround, which, unfortunately seems to not work on macOS.

  • leptos

    Build fast web applications with Rust.

  • Project mention: Migrating a JavaScript frontend to Leptos, a Rust framework | dev.to | 2024-03-26

    Lots of new frontend frameworks have been built on top of Rust, including Leptos, which happens to be one of the most popular ones. In this guide, we'll highlight why and how to migrate your JavaScript frontend to use the Leptos Rust frontend framework.

  • TinyGo

  • Project mention: Cylon: JavaScript framework for robotics, drones, and the Internet of Things | news.ycombinator.com | 2024-05-04
  • wasmtime

    A fast and secure runtime for WebAssembly

  • Project mention: Backdoor in upstream xz/liblzma leading to SSH server compromise | news.ycombinator.com | 2024-03-29

    Just a documentation change, fortunately:


    They've submitted little documentation tweaks to other projects, too, for example:


    I don't know whether this is a formerly-legitimate open source contributor who went rogue, or a deep-cover persona spreading innocuous-looking documentation changes around to other projects as a smokescreen.

  • Pion WebRTC

    Pure Go implementation of the WebRTC API

  • Project mention: VoRS: Vo(IP) Simple Alternative to Mumble | news.ycombinator.com | 2024-04-19
  • pyodide

    Pyodide is a Python distribution for the browser and Node.js based on WebAssembly

  • Project mention: Py2wasm – A Python to WASM Compiler | news.ycombinator.com | 2024-04-22

    We implemented an in-browser Python editor/interpreter built on Pyodide over at Comet (our users are data scientists who need to build custom visualizations quite often, and the most familiar language for most of them is Python).

    One of the issues you'll run into is that Pyodide only works by default with packages that have pure Python wheels available. The team has developed support for some libraries with C dependencies (like scikit-learn, I believe), but frameworks like PyTorch are particularly thorny (see this issue: https://github.com/pyodide/pyodide/issues/1625 )

    We ended up rolling out a new version of our Python visualizations that runs off-browser, in order to support enough libraries/get the performance we need: https://www.comet.com/docs/v2/guides/comet-ui/experiment-man...

    Also, it would be nice if there was a WASM (soft) CPU for QEMU, which (if it existed!) would go here:


  • awesome-blazor

    Resources for Blazor, a .NET web framework using C#/Razor and HTML that runs in the browser with WebAssembly.

  • libsql

    libSQL is a fork of SQLite that is both Open Source, and Open Contributions.

  • Project mention: Show HN: Roast my SQLite encryption at-rest | news.ycombinator.com | 2024-04-30

    > PS: I've got nothing against Turso, or libSQL. In fact I spent the last year perusing their virtual WAL API. The problem is that I found no documentation, nor any useful open source implementations of it. If there any I'd be very interested. So, thus far, I also don't have anything that drives towards libSQL.

    Hey, this is v and I am an engineer at Turso. We do have some documentation and an example implementation of Virtual WAL

    docs: https://github.com/tursodatabase/libsql/blob/ef44612/libsql-...

    example: https://github.com/tursodatabase/libsql/blob/ef44612/libsql-...

    for an open source implementation, you may check how Bottomless works. Bottomless is another project which does back up like litestream and it internally implements a Virtual WAL.

    Bottomless - https://github.com/tursodatabase/libsql/tree/main/bottomless

    I am sure we can improve our docs, make it more discover-able and easy to find. I am open to feedback and suggestions!
