There are a number of companies working on solving micro-VM sandboxes, using Firecracker or libkrun. This includes CodeSandbox, E2B and Microsandbox. One of the major use cases is running AI-generated code in a safe environment, with the promise of fast (~2-300 ms) bootup times, pre-built memory snapshots, and the ability hibernate and wake up instances extremely fast. The downside is these solutions still have... - Source: Hacker News / 4 months ago

I started writing about the shiny new wasm-y not quite open source tech called webcontainers by stackblitz, but having hacked the crap out them I reckon right now they aren't quite mature enough for production use. - Source: dev.to / 12 months ago

I don't know about using QJS, but if you want to run a bundler in the browser that sounds like the sort of thing that WebContainers[1] were built for. [1]: https://webcontainers.io/. - Source: Hacker News / about 1 year ago

We'll use some innovative technologies, including WebContainers, CodeMirror, and XTerm, to build this. If you're not familiar with these, don't worry, we'll cover them all during the process. - Source: dev.to / almost 2 years ago

How does it work? There is no backend whatsoever. The API Security Academy leverages WebContainers, a new technology that allows running full-blown node instances directly in the browser. Each WebContainer contains a live GraphQL application, so you'll not only understand why a vulnerability is risky, but also how to exploit it and, most importantly, how to fix it.

Wrong, Flash was in the process of doing exactly that. https://adobe-flash.github.io/crossbridge/ Before asm2js was even an idea, Unreal compiled to Flash via CrossBridge. https://www.youtube.com/watch?v=xzyCTt5KLKU https://www.youtube.com/watch?v=ZmZS7B1pLWg To this day, with exception of maybe PlayCanvas, there are hardly any tools that can match the same developer experience for WebGL, almost 15 years later. - Source: Hacker News / 7 months ago

Already offered by PNaCL, and CrossBridge, in 2010. https://adobe-flash.github.io/crossbridge/ Still waiting for those wonderful WebAssembly + WebGL games that can match Infinity Blade for iOS from 2010, the game Apple used to show off iOS GL ES 3.0 capabilities. - Source: Hacker News / about 2 years ago

Historical note, it was originally done as UE3 to Flash C++ Crossbridge / Stage 3D, the WebGL version came later. https://www.shacknews.com/article/72813/epic-releases-epic-citadel-unreal-engine-demo-in-flash "Unreal Engine 3 Support for Adobe Flash Player - Epic Citadel" -- https://www.youtube.com/watch?v=xzyCTt5KLKU https://help.adobe.com/en_US/as3/dev/WSF24A5A75-38D6-4a44-BDC6-927A2B123E90.html. - Source: Hacker News / over 2 years ago

It is basically Flash, but now it is standard, so everyone is happy. https://adobe-flash.github.io/crossbridge/ https://youtu.be/xzyCTt5KLKU. - Source: Hacker News / about 3 years ago

Easy, so many reasons beyond just blaming Apple, - WebGL is a subset of ES 3.0, when the hardware can do GL 3.2 - WebGPU, when it arrives sometime during 2022, it will be a 1.0 MVP of the features from Metal, Vulkan and DX 12, with yet another shading language that looks like a mix of C++/HLSL/Rust, WGSL. - Lack of tooling, to debug WebGL you have basically to debug the browser process and try to track down your... - Source: Hacker News / almost 4 years ago
