    I know of https://github.com/therecipe/qt, but I've no experience using it, so not sure how well it works. But normally if you feel handy with Go, I guess it should be easier than switching your development stack to C++.

  • mal

    mal - Make a Lisp

    Project mention: Llisp: Lisp in Lisp | news.ycombinator.com | 2022-01-23

    Also see Make a Lisp - a build a lisp project that has a specific section on tail recursion [0]. When I went through the MAL process, TCO was actually one of the more straight forward sections (compared with say macros). The basic idea is quite simple - take your eval function and wrap it's body in a loop. For several of the special forms, instead of recursing, rebind eval's arguments and go back round the loop. Forms where something is done after the call to eval still have to recurse, but they are actually in the minority.

  • wasmtime

    Standalone JIT-style runtime for WebAssembly, using Cranelift

    Project mention: WebAssembly: The New Kubernetes? | news.ycombinator.com | 2022-01-21

    > But, in WebAssembly you get a few more things. One is fast start.

    This is one of the key things I think is differentiating versus the container world. The idea of per-request instantiation is possibly within reach. This is a possible return to a very old, very simple architectural pattern, of cgi-bin! Running a process per request. Which we left because creating processes was expensive. Our new architectures- discussed in this write up- revolve around long running applications, which are compelled upon us for performance reasons. But WebAssembly seems well suited to very fast instantiation of new contexts. It re-opens the possibility that we can have (return to) smaller more discrete chunks of work, safer little units of execution running. We could go back to a Apache HTTPD style prefork world, the very old[1]!

    This is part of the gradient we've been walking down, it feels like. VMs -> containers -> lighter weight containers. Returning to finer grained processes.

    For anyone interested in a deep dive into some of the super neat systems programming going into making WebAssembly starts/instantiation fast, there's a bunch of active work to reengineer module instantiation, using memfd [2][3]. Really fun to see this getting hashed out.

    > * So one answer to the question as initially posed is that no, WebAssembly is not the next Kubernetes; that next thing is waiting to be built, though I know of a few organizations that have started already.*

    And as others have recommended, worth noting Krustlet[4], which allows running WebAssembly instances via Kubernetes. This could definitely make sense for a lot of our workloads. I think a lot of people also expect though that the cloud infrastructure itself will get rewritten or recompiled into webassembly. Where-as today we tend to wire systems together over protocols, via http or grpc, we'll be able to more directly stitch together plugably modular systems, where a generic control process to govern, i dunno pick an example, load balancers say, has a bunch of specific webassembly modules plugged in with the specific actuators / configuration for your set up. There's a real potential to fulfill much of the idea of micro-kernels here, of decomposing big applications into looser assemblages of generic code, drivers, and configuration.

  • awesome-blazor

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

    Project mention: Advancing in C#/becoming a senior dev | reddit.com/r/csharp | 2022-01-10

    It is usually true that Microsoft's documentation falls behind their implementations, but it does eventually catch up. But this: https://docs.microsoft.com/en-us/aspnet/core/blazor/?view=aspnetcore-6.0 isn't all that bad. There are a lot of resources here https://github.com/AdrienTorris/awesome-blazor too.

  • Uno Platform

  • genact

    🌀 A nonsense activity generator

    Project mention: I made a tool you guys can use for producing advanced Linux memes | reddit.com/r/linuxmemes | 2021-04-20
  • binaryen

    Compiler infrastructure and toolchain library for WebAssembly

    Project mention: Migrating a JavaScript Library from JavaScript to WebAssembly | news.ycombinator.com | 2021-02-11

    The binaryen toolkit comes with a wasm2js tool, you could translate the wasm back to js and see how performance compares ;)

    It's possible that performance isn't all that different, because asm.js-style Javascript can be surprisingly fast (compared to "idiomatic" human-written Javascript).

    Otherwise it's a completely pointless excercise of course, unless you need to support browsers without WASM support (which don't exist anymore AFAIK).

  • vim.wasm

    Vim editor ported to WebAssembly

    Project mention: Why do most self-taught programmers end up doing front-end web devleopment? | reddit.com/r/cscareerquestions | 2021-10-31

  • vugu

    Vugu: A modern UI library for Go+WebAssembly (experimental)

    Project mention: Ask HN: Should I even bother with React? | news.ycombinator.com | 2022-01-23

    If you have the option go for https://www.vugu.org/ and use the go language. Much better language started by google in 2006 vs JavaScript which was started in I think 1995?

    Project mention: Open source Business intelligence platform made with Python | news.ycombinator.com | 2021-11-28
  • wabt

    The WebAssembly Binary Toolkit

    Project mention: Understanding WebAssembly better by learning WebAssembly-Text | dev.to | 2021-08-15

    WebAssembly is a true revolution in tech, not just in the web, but thanks to WASI and friends, it is becoming available everywhere. One of the best things WebAssembly offers is being a compilation target instead of just another programming language. This has the potential to help a lot of non-JS developers get involved with web development. WebAssembly also has its text version called... You got it, WebAssembly Text, or WAT for short! (MDN docs here). It can be compiled to the binary format using WABT.

  • lucet

    Lucet, the Sandboxing WebAssembly Compiler.

    Project mention: There are a *lot* of actor framework projects on Cargo. | reddit.com/r/rust | 2021-05-01

    I guess lucet could be an under-layer for this but it's not really the same, different levels of the stack. Fascinating.

  • ant-design-blazor

    🌈A set of enterprise-class UI components based on Ant Design and Blazor WebAssembly.

    Project mention: Best UI components for commercial enterprise project? | reddit.com/r/Blazor | 2021-11-25

    AntBlazor is the best for me. You can try.

  • magnum
