Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…

cubic▲733Hey HN, I'm Paul, the founder of cubic.dev, an AI code reviewer for complex codebases. Over the past few months we’ve completely rebuilt our detection engine, and I wanted to share a few things we did to get more out of LLMs. Context: cubic specializes in code reviews for teams with complex codebases, like Better Auth, Cal.com, and PostHog. Our users have high standards. It’s important that reviews have real depth and actually understand the codebase. In the past, we've sometimes struggled with producing reviews that had deep insight into complex changes. It didn't feel like we were leaving…

Comp AI▲612Hey HN, We’re the founders of Comp AI (https://github.com/trycompai/comp), an open source alternative to Drata & Vanta. Our goal is to help 100,000 companies get compliant with frameworks like SOC 2, ISO 27001 and GDPR over the next five years. To support that goal, we’re trying to make the platform as self serve as possible - so founders who’ve never been through the process can start to get compliant at any stage. Any feedback is appreciated

Finally got my hobby OS up and running on real hardware. I love the old IBM thinkpads, so thought it was the perfect machine to get it working on. Been working on it for quite some time now, but this has been a big milestone!

I sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha. I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API. This…

I've been working on a little side project that combines Duolingo-like listening comprehension exercises with real content . Every video is transcribed to get much better transcripts than the closed captions. I filter on high quality transcripts, and afterwards a LLM selects only plausible segments for the exercises. This seems to work well for quality control and seems to be reliable enough for these short exercises. Would love your thoughts!

Hi HN, I've been working on this project for the last 5 months, inspired by Screen Studio but runs 100% in the browser. Here is a demo of the editor: https://www.youtube.com/watch?v=k7-etsFZgPI One of the big challenges of using the browser is getDisplayMedia, the API for recording screens, doesn't provide mouse coordinates for security reasons. Mouse coordinates are important for auto-focus animations. So I trained a YOLOv11 model to detect mouse cursors and I run inference in real time while you record. Also, I created my own Remotion-style renderer because I started with…

Hi HN! I made Beatsync, an open-source browser-based audio player that syncs audio with millisecond-level accuracy across many devices. Try it live right now: https://www.beatsync.gg/ The idea is that with no additional hardware, you can turn any group of devices into a full surround sound system. MacBook speakers are particularly good. Inspired by Network Time Protocol (NTP), I do clock synchronization over websockets and use the Web Audio API to keep audio latency under a few ms. You can also drag devices around a virtual grid to simulate spatial audio — it changes the…
