High performance secure & portable Rust functions in Node.js

  1. 1SS

    Raw performance (the lack of) is always a contentious point for JavaScript, especially in our post-Moore era of computing. Node.js gets around this issue through extensive of use of native libraries and modules written in C, including the V8 JS engine itself. But as application developers, how do YOU create high performance functions? Write in C and run as a NAPI module? Write in Rust and run as a V8 wasm? Well, there is another (better and faster) way now! The SSVM is a fully featured WebAssembly VM that is optimized for server-side applications.…

    Hi, over the past few months I've been working on this project: Numax is a small Rust runtime that does three things: it runs WebAssembly modules in a sandbox, has a built-in local key-value store, and syncs everything across nodes with CRDTs and gossip. Basically, you write a wasm module, run it on two machines, and they converge (I hope !). It's a decentralized system... I hope someone finds it interesting! There's a whitepaper I've put a lot into, and I think the code isn't bad either! I believe there's still room in this world for software that's fun and well made, and while building…

    Over the past few months, as we scaled our internal AI Agents, we hit a dead end: Running LLM-generated arbitrary code in Docker is basically running naked on security due to container escape risks. But using full traditional VMs takes minutes to boot and eats too much memory to support high-density concurrency. We loved the developer experience of SaaS sandboxes on the market, but they are closed-source, expensive, and have too high a barrier to entry for self-hosting. So, our team decided to build our own. After months of grinding, using RustVMM and KVM, we built a blazing-fast,…

    I’ve been experimenting with building a Node.js HTTP framework using Rust + Hyper with N-Api. The project started as a fully synchronous server, but I recently patched it to support async (Tokio/Hyper). That change alone nearly doubled throughput in benchmarks. What’s different: * Built directly on Hyper, no heavy abstraction * napi glue for Node.js bindings * Minimal core (sync and async engines side-by-side) * Focused on raw performance, not plugins (yet) This is still experimental and not production-ready. I’d like feedback on: * Async API design — does it feel ergonomic? *…

    Hi, I've made a Dis virtual machine and Limbo programming language compiler (called RiceVM) in Rust. It can run Dis bytecode (for example, Inferno OS applications), compile Limbo programs, and includes a fairly complete runtime with garbage collection, concurrency features, and many of the standard modules from Inferno OS's original implementation. The project is still in an early stage, but if you're interested in learning more about RiceVM or trying it out, you can check out the links below: Project's GitHub repo: https://github.com/habedi/ricevm RiceVM documentation:…

    Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack…

    Hi HN! I've been building a project that handles high-value credentials in-process, and I wanted something more robust than just zeroing memory on drop. A comment on a recent Show HN[0] made me realize that awareness of lower-level memory protection techniques might not be as widespread as I thought. The idea here is to pull out all the tools in one crate, with a relatively simple API. * mlock/VirtualLock to prevent sensitive memory from being swapped (eg the KeePass dump) * Core dump exclusion using MADV_DONTDUMP on Linux & Android * mprotect to minimize exposure over time * Guard…
