Show HN: Fixing AI's Core Flaws, A protocol cuts LLM token waste by 40–70%https://news.ycombinator.com/item?id=47045604WLM (Wujie Language Model), a protocol stack + world engine that rethinks AI from token prediction to structural intelligence. I built this to fix the problems we all deal with daily: hallucination, drift, uncontrollable behavior, black-box reasoning, unstructured knowledge, and chaotic world/agent generation.The Pain We Can’t Keep IgnoringCurrent LLMs/agents are token predictors, not intelligences. They suffer from:• Hallucination: No grounded structure → guesses instead of knowing.• Persona drift: Personality is prompt-hacked, not structural.• Uncontrollable behavior: Sampling, not deterministic structure.• Black-box reasoning: No traceable reasoning path.• Knowledge soup: Embeddings/vectors, no formal structure.• Fragile world models: Prediction, not interpretable structure.• Random generation: No consistent causal/world rules.We’ve patched these with RAG, fine-tuning, prompts, RLHF — but they’re band-aids on a foundational flaw: AI lacks structure.How WLM Solves ItWLM is a 7-layer Feb 17, 2026 10:01 AM

Show HN: CoolWulf AI – A personal AI assistant built in Go, optimized for macOShttp://coolwulfAI.comHey HN,I've been building CoolWulf AI (https://coolwulfai.com), a self-hosted personal AI assistant. After seeing OpenClaw blow up, I wanted to share what I've been working on — a different approach to the same problem.*Why I built this:*I tried OpenClaw and found the Node.js/TypeScript stack heavy for what's essentially a local agent. pnpm, Node 22+, React — lots of moving parts. I wanted something that's a single binary, zero runtime dependencies, and feels native on macOS. So I built it in Go.*How it's different from OpenClaw:*- *Single binary, no runtime needed.* Download, set your API key, run. No Node.js, no pnpm, no build step. One ~100 MB binary. - *Built in Go.* Fast startup, low memory footprint, compiles to a native executable. No garbage collector pauses from a JS runtime sitting in the background. - *macOS-native integrations.* Deep AppleScript-based control of Apple Notes, Reminders, Calendar, Terminal.app, and WeChat desktop. These aren't browser hacks — they use the natFeb 17, 2026 5:32 AM

Ask HN: Where does modern geometry survive contact with SGD?https://news.ycombinator.com/item?id=46882060Over the past year I worked through Frankel’s “The Geometry of Physics” cover to cover, not to relearn physics, but to rebuild a modern geometric toolbox as it is actually used there: manifolds, differential forms, connections and curvature, Lie groups and algebras, fiber bundles, gauge structure, and variational principles.The motivation was practical rather than theoretical:Which of these geometric structures, if any, actually survive discretization, noise, and SGD-style training in modern machine learning?In physics, global and coordinate-free formulations were not aesthetic choices; they were forced when local reasoning stopped working. A recurring structural pattern was:structure -> symmetry -> invariance -> dynamics -> observablesIn modern ML we increasingly see analogous issues:* parameter symmetries and large quotient spaces * non-Euclidean data (graphs, meshes, manifolds) * highly structured hypothesis classes * training dynamics that are not well-described by flat Euclidean oFeb 4, 2026 6:07 AM

Show HN: I built a GPT that breaks logic into jokeshttps://humoropedia.com/I always loved comedy and humor in all their manifestations. I always loved comedy movies and standup routines. I also truly believed - and still believe - that laughter is an excellent medicine, not the best medicine though.That love for humor led me to the creation of Humoropedia.com. At its height of popularity, it was receiving about 200 thousand visitors a month, mostly from Google Search.Now that we have entered an age of AI - for better or worse, who knows - I decided that Humoropedia.com should become AI-enabled because these days you can be either AI-disabled or AI-enabled. So I chose to make Humoropedia.com AI-enabled, or at least as AI-enabled as a GPT Builder would allow me.That's how Humoropedia GPT was born.

Show HN: Skill capsules" for LLMs, a "poor man's continual learning"https://github.com/killerstorm/set_v4/blob/main/REPORT.md"Continual learning" is considered one of the "blockers" for LLMs: they can't learn on the job, don't improve over time, etc. In particular, Dwarkesh Patel describes it as a number of problem which has to be solved to get to AGI.Many academic article propose some kind of a memory system for LLM which might be considered a form of "continual learning". But most evals focus on memorizing facts which is just not very useful (it's better to fetch facts via tool use than to store it in neural memory) and these proposals might not fit well into common LLM API use patterns.In this article I'm proposing a "new" method called "skill capsules" which is highly pragmatic, easy to understand and evaluate and might integrate well into existing tooling.Skill capsule is a concrete object - it's a bunch of vectors, basically. You can insert it somewhere into a middle of LLM context and it improves performance on a particular skill, e.g. get tool calls more reliable, use particular writing style, codingDec 20, 2025 9:46 PM

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.
