Smelt — an open source test runner for chip developers
Hey everyone, James from Silogy here. We’re excited to open-source our test runner, Smelt. Smelt is a simple and extensible test runner optimized for chip development workflows. Smelt enables developers to: * Programmatically define numerous test variants * Execute these tests in parallel * Easily analyze test results As chip designs get more complex, the state space that needs to be explored in design verification is exploding. In chip development, it's common to run thousands of tests, each with multiple hyperparameters that result in even more variation. Smelt offers a straightforward…

Open-source user onboarding and KYC flow made with Svelte (~50kb)2022 · github.com · ▲254Hi everyone, We’re building an open-source identity and risk management platform and we’ve just released the first chunk of code, a fully customizable KYC flow & UI, to the public. We’ve chosen to use Svelte so our flows would be lightweight (it is ~50kb gzipped). Next up: - Adding forms and components for it to be used as a full onboarding flow. - Releasing an open-source case management dashboard, for manual approval of users. - Releasing an open-source rule engine, to help automate decisions. We’d love to hear your feedback, suggestions, or any question you’ve got. And if the rest of the…

Run – a CLI universal code runner I built while learning Rust2025 · github.com · ▲96Hi HN — I’m learning Rust and decided to build a universal CLI for running code in many languages. The tool, Run, aims to be a single, minimal dependency utility for: running one-off snippets (from CLI flags), running files, reading and executing piped stdin, and providing language-specific REPLs that you can switch between interactively. I designed it to support both interpreted languages (Python, JS, Ruby, etc.) and compiled languages (Rust, Go, C/C++). It detects languages from flags or file extensions, can compile temporary files for compiled languages, and exposes a unified REPL…
- FEFleet – Experimental build tool for Rust that’s up to 5x faster2022 · ▲63
Fleet is an experimental fast, lightweight, open-source, build tool for Rust. Builds with Fleet enabled are up-to 5x faster! For a production repository (infinyon/fluvio) which we tested, we were able to cut down our incremental build times from 29 seconds down to 9 seconds, boosted by Fleet. We saw even better results on dimensionhq/volt, with our build times cut down from 3 minutes to just 1 minute - a 3x speed improvement! How does fleet work? Fleet works by optimizing your builds using existing tooling available in the Rust ecosystem, including seamlessly integrating sccache,…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
