Show HN: OmnAI – Sovereign AI infrastructure with multi-vault isolationhttps://github.com/TadTanyaTalaTadenTadhgTaya/OmnAI-v3.5Hey HN! I built OmnAI because enterprises keep telling me they can't deploy AI due to compliance barriers.The problem: Defense contractors need air-gapped LLMs. Hospitals want AI but fear HIPAA violations. Banks need audit trails for every AI decision. Current solutions either lock you into cloud providers or leave you on your own for security.OmnAI provides: - 16 isolated vaults using gVisor sandboxing (zero data leakage between tenants) - Trust-based governance - mandatory human review when confidence drops below 0.90 - Three deployment tiers: SUPERFLY (air-gap/DoD IL6), SOVEREIGN (on-prem/finance), EXCEED (hybrid/R&D) - Compliance-ready architecture (FedRAMP, HIPAA, SOC, ITAR)Technical stack: vLLM/Triton for inference, offline PKI with AES-GCM-256, per-vault fine-tuning pipelines.It's in pilot state - I'm looking for feedback on whether this architecture resonates with production AI challenges you're seeing, especially around data sovereignty and regulatory compliance.https://github

The Army’s contribution to joint space operationshttps://spacenews.com/the-armys-contribution-to-joint-space-operations/Recent analysis by Reeves in the Mitchell Institute’s “Charting a Path to Space Superiority: The Cross-Domain Imperative” identifies the need for centralized command and control (C2) of counterspace capabilities under U.S. Space Command to ensure unity of effort. However, Reeves’s critique of the United States Army’s development of counterspace capabilities fundamentally misunderstands the Army’s role […] The post The Army’s contribution to joint space operations appeared first on SpaceNews.

Show HN: An MPSC Queue Optimizing for Non-Uniform Bursts and Bulk Operationshttps://github.com/dakingffo/MPSC_queueHi HN,I’m a C++ student and I’ve spent the last few months obsessing over concurrent data structures. I’m sharing daking::MPSC_queue, a header-only, lock-free, and unbounded MPSC queue designed to bridge the gap between linked-list flexibility and array-based throughput.1. FACING THE CHALLENGE: THE "LINKED-LIST BOTTLENECK" In traditional MPSC linked-list queues, if multiple producers attempt to enqueue single elements at a high, uniform frequency, the resulting CAS contention causes severe Cache Line Bouncing. In these saturated uniform-load scenarios, throughput hits a physical "floor" that often underperforms compared to pre-allocated ring buffers.2. ARCHITECTURAL SOLUTIONS FOR REAL-WORLD SCENARIOS Rather than focusing on average throughput under uniform load, this design targets two specific real-world challenges:Scenario A: Non-Uniform Contention (Burst Resilience) In many systems, producers are mostly idle but burst occasionally. By facilitating a high-speed lifecycle where node c

Launch HN: Kenobi (YC W22) – Personalize your website for every visitorhttps://news.ycombinator.com/item?id=46301865Hey HN! We’re Rory, Chris, and Felix from Kenobi (https://kenobi.ai). Kenobi lets you add AI-based content personalization to any website. As a site owner, you install our personalization widget with a script tag, just like you would for e.g. a chatbot integration. As a visitor, you interact with the widget (right now by providing a company name) and Kenobi changes the site content to suit you.We’ve built a demo that anyone can try here: https://kenobi.ai/startWe believe that large parts of the web are about to go from being static to dynamic because of how adept LLMs are at transforming rendered HTML. And right now we’re focussing on B2B landing page content (as opposed to application UIs) because there is a lot of commercial opportunity for increasing top-of-funnel inbound conversions.Our journey to Kenobi today is a long and snaking one. You may notice from the post title that we did YC’s Winter 2022 batch (I know that 4 years is practically ancient in YC-dog-years). Kenobi is a har

Show HN: I built a deterministic vector DB kernel in Rust using fixed-point mathhttps://github.com/varshith-Git/Valori-KernelWhile building a vector database in Python (valori: https://pypi.org/project/valori/), I ran into a bug that took longer than I want to admit.The same embeddings, indexed on macOS and Windows, would sometimes produce slightly different nearest-neighbor results. Nothing dramatic but enough to break tests and make snapshots non-reproducible.At first I assumed it was my code. Then I realized the problem wasn’t my logic at all it was "floating-point math".Different CPUs, different compilers, FMA instructions, and subtle differences in IEEE behavior meant that “the same” computation wasn’t actually the same everywhere.That sent me down a rabbit hole.The idea:Instead of trying to fight floating-point nondeterminism, I asked a simpler question:What if the core of a vector system never used floats at all?So I built a small kernel in Rust that uses fixed-point arithmetic (Q16.16) for all vector math. No floats in the core. No randomness. No architecture-dependent behavior.Same inputs → same sta

Choosing the Right Stainless Steel Utility Sink for Heavy-Duty Usehttps://news.ycombinator.com/item?id=46297672In industrial and commercial environments, every piece of equipment plays a role in keeping operations efficient, safe, and hygienic. Among these essentials, the utility sink often works quietly in the background, yet it supports countless daily tasks. From manufacturing plants to commercial kitchens and maintenance workshops, choosing the right stainless steel utility sink for heavy-duty use can make a measurable difference in workflow and durability.Heavy-duty environments place higher demands on sinks than residential spaces. They are used for washing tools, handling raw materials, cleaning components, and managing waste liquids. A well-designed sink must withstand frequent impact, exposure to chemicals, and constant moisture without compromising performance or hygiene. This is where stainless steel stands out as a preferred material across the metal fabrication and industrial equipment sectors.One of the first factors to consider is material grade and thickness.

Show HN: I built a fast RSS reader in Zighttps://github.com/superstarryeyes/hysWell, I certainly tried. I had to, because it has a certain quirk inspired by "digital minimalism."The quirk is that it only allows you to fetch new articles once per day (or X days).Why? Let me explain...I want my internet content to be like a boring newspaper. You get it in the morning, and you read the whole thing while sipping your morning coffee, and then you're done! No more new information for today. No pings, no alerts, peace, quiet, zen, etc.But with that, I needed it to be able to fetch all articles from my hundreds of feeds in one sitting. This is where Zig and curl optimisations come in. I tried to do all the tricks in the book. If I missed something, let me know!First off, I'm using curl multi for the network layer. The cool thing is it automatically does HTTP/2 multiplexing, which means if your feeds are hosted on the same CDN it reuses the same connection. I've got it configured to handle 50 connections total with up to 6 per host, which seems to be the sweet spot before

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
