I want to build a product, not another generic image generatorhttps://news.ycombinator.com/item?id=46292364AI's generative capabilities are really powerful now, and it can produce all sorts of materials. However, if you want to use AI-generated materials in your daily work, the general AI products' image generation capabilities might not fully meet your needs.Every time AI generates something, it consumes points. The generated images are like opening a blind box; they can't really meet all sorts of needs. For example, I want to generate materials of specific sizes and types, and I want to create various materials of the same type.What I'm thinking is, can we develop a way to limit the general AI's image generation capabilities to a specific aspect? I'm not looking to see what AI can create; I want AI to provide me with what I want.For example, if I want to create a 2D game, I need a set of usable game assets. I need to provide some parameter options: what kind of game assets, characters, items, or scene backgrounds? What style, hand-drawn, pixel, cartoon, or realistic?For example, I want to

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

Veteran-built iPhone steadiness tracker to help people avoid fallshttps://news.ycombinator.com/item?id=46226464Hi HN — I’m a veteran founder working on something deeply personal: helping people (including a lot of veterans and aging adults) stay on their feet longer.We’re building PinkSteady — an app that uses the iPhone’s IMU data to estimate steadiness and deliver adaptive balance training in short daily sessions.The problem: Falls destroy independence, cost the healthcare system billions, and most “fall prevention” solutions exist only inside clinics. There are balance exercises online, but compliance is extremely low. We’re trying to make steadiness training simple + habitual + measurable.Technical challenge: Consumer-grade IMUs are noisy. Gait patterns vary wildly. Most people do not want to strap on sensors or buy devices, so we’re trying to extract useful low-frequency stability features from phones people already have — placed inconsistently in pockets, belts, hand, etc.We’ve found:– gravity vector drift matters – window length selection changes user trust – feedback timing affects beha

Ask HN: Who Is Working to Combat AI-Powered Fraud?https://news.ycombinator.com/item?id=46137711There has been a recent explosion in AI-aided scams and fraud. Deepfakes (both video and voice), web scraping, and automated document generation have allowed scammers to target victims with more precision and believability than was ever possible before AI.All of this has always been possible to some degree, but "quantity has a quality all its own" continues to ring true.Public education ("scam awareness") is obviously the most decisive strategy, but is generally left to the underfunded public sector or the PR departments of banks, etc.As for AI-industry regulation, I'm not holding my breath. And besides, with open-source models there will always be products available to bad actors.So is anyone working on anything in the public interest? Any bright ideas?
