Show HN: Sub-microsecond (890 ns) trading execution research systemhttps://submicro.krishnabajpai.me/I am sharing a research-grade, open-source trading execution framework that achieves a median end-to-end decision latency of 890 nanoseconds on commodity hardware.The project is designed for education, systems research, and latency instrumentation, not for live trading. It focuses on understanding exactly where every nanosecond goes in a trading execution path.Key features:- Kernel-bypass networking: Direct userspace access to NICs via custom drivers, 20-50 ns RX latency - Lock-free SPSC/MPSC queues: Zero-copy architecture - SIMD feature extraction: About 40 ns per update using AVX-512 - Deterministic replay: Bit-identical execution paths, SHA-256 verified - Nanosecond-level metrics: Full audit logs and performance dashboardTechnical stack: C++17 and Rust, NUMA-aware memory allocation, cache-line alignment, inline assembly for hot paths.The framework is modular, allowing experimentation with different NIC drivers, feature extraction pipelines, or order-flow models such as Hawkes proces

What Is PVD? Understanding Its Role in Vacuum Coating Technologyhttps://news.ycombinator.com/item?id=46272254Physical Vapor Deposition (PVD) is a key technology in modern manufacturing, used to apply thin, durable coatings to materials in a vacuum environment. This advanced coating process has revolutionized many industries, including automotive, electronics, aerospace, and decorative products. As industries increasingly demand high-performance materials and superior coatings, vacuum coating machines have become essential in achieving these goals.At the heart of PVD technology is the deposition of vaporized material onto a substrate in a vacuum. This method allows for the creation of extremely thin, uniform coatings with precise control over their composition and thickness. The ability to apply these coatings to a variety of materials, such as metals, plastics, and ceramics, has made PVD an indispensable tool across many sectors.Vacuum coating machines are designed to meet the demands of these applications by offering precise control over the coating process. These machines vary in size and d

Show HN: I made a human-in-the-loop system for tuning LLMs in betahttps://www.joinoneshot.com/OneShot is an API that routes failed LLM outputs to trained humans, returns corrected outputs or prompt injections, and stores the edits as structured training data.Privacy Note: This product is not built for privacy yet. The current use case is internal tools or beta features where users aren’t promised privacy. But the point of this tool is NOT FOR PRODUCTION.In the future, there will be a feature for anonymizing all private information automatically.Problem: My project this year was a tool for pediatricians to do their insurance claims assisted by AI.Niche industries like this require a ton of examples, fine-tuning and re-prompting to actually get them a product that works. Then, it requires monitoring the output to some extent (of course with the hospital’s consent) so small model changes or edge cases don’t break outputs for at least the first couple months.This monitoring takes months of being distracted from doing new features. And every new feature I wanted to ship required thi

Fake "Dynamic Island for Mac" app is impersonating my product, spreading malwarehttps://news.ycombinator.com/item?id=46230333Someone created a fake version of my app that copies the name, icon, and even re-uploaded my demo video on YouTube. Some users installed it believing it was legitimate. The fake .dmg instructs users to drag files into Terminal something my real app never does. Jamf has already published an analysis of this malware variant, which includes a fake “DynamicLake.dmg” as one of the distribution vectors. Several users contacted me after installing it, but as a solo developer I don’t have the tools to help remove malware I didn’t create. Google/YouTube abuse reports haven’t resulted in takedowns so far. I’d appreciate advice from anyone who has dealt with malicious clones or knows effective ways to handle abuse reports and protect users. More details and verification tips in the first comment

Show HN: Titan – JavaScript-first framework that compiles into a Rust serverhttps://www.npmjs.com/package/@ezetgalaxy/titanHi HN,I built Titan, a backend framework where you write routes and logic in JavaScript, and the CLI compiles everything into a single Rust + Axum binary using the Boa JS engine. No Node.js is required in production.The idea is to keep JS developer experience while getting Rust performance and a self-contained deployable server.Current features:JS route DSLAction system mapped to Rustesbuild bundlingGenerated Rust server with AxumHot-reload dev serverSingle-binary outputRepo: https://github.com/ezet-galaxy/-ezetgalaxy-titanWould love feedback on the architecture, DX, and whether this hybrid JS→Rust approach is useful.Thanks for reading!
