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.

Yes, C can be simple for writing a compiler. [0][1] No, optimisation, on the other hand, is not a simple problem. [0] https://github.com/rui314/8cc [1] https://github.com/rui314/chibicc. - Source: Hacker News / over 3 years ago

Implement a compiler for a subset of C. This doesn't need to be self-hosting, but bonus points if it is. Here's an example of what it can look like: https://github.com/rui314/8cc. Source: over 4 years ago

While this is an impressive work, I feel that there are a lot of "tiny" C compilers out there; how is yours any different than SmallerC, TinyC, 8cc, chibicc and many others? Source: over 4 years ago

Great question. Here are some candidates: * https://github.com/rswier/c4 * https://github.com/Fedjmike/mini-c * https://github.com/rui314/8cc * https://github.com/rui314/chibicc * https://github.com/aligrudi/neatcc Some of them are actually interpreters, and I personally would be interested in actual compilers that generate machine code. - Source: Hacker News / over 4 years ago
