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

Show HN: WarpParse – Rust ETL engine 1.5–8x faster than Vectorhttps://news.ycombinator.com/item?id=46880903Hey HN, We’ve been working on WarpParse, an open-source (Apache 2.0) ETL engine built in Rust, and we’re excited to share it with you today. We built it because we found that existing tools often struggled with resource efficiency or configuration complexity when handling massive log volumes. WarpParse aims to solve this with: Performance: 1.5x to 8x higher throughput than Vector in our benchmarks. Efficiency: Uses ~1/3 the CPU and ~37% of the memory of Vector under similar loads. DSLs: We created WPL (Warp Parse Language) for strong-typed parsing and OML (Object Modeling Language) for declarative data enrichment with native SQL integration. We’ve also built a visual editor (WpEditor) to make rule-writing less of a headache. We’d love to hear your thoughts on the architecture, the DSL approach, or any feedback you have after checking out the repo.

Show HN: OpenSymbolicAI – Agents with typed variables, not just context stuffinghttps://news.ycombinator.com/item?id=46876687Hi HN,We've spent the last year building AI agents and kept hitting the same wall: prompt engineering doesn't feel like software engineering. It feels like guessing.We built OpenSymbolicAI to turn agent development into actual programming. It is an open-source framework (MIT) that lets you build agents using typed primitives, explicit decompositions, and unit tests.THE MAIN PROBLEM: CONTEXT WINDOW ABUSEMost agent frameworks (like ReAct) force you to dump tool outputs back into the LLM's context window to decide the next step.Agent searches DB.Agent gets back 50kb of JSON.You paste that 50kb back into the prompt just to ask "What do I do next?"This is slow, expensive, and confuses the model.THE SOLUTION: DATA AS VARIABLESIn OpenSymbolicAI, the LLM generates a plan (code) that manipulates variables. The actual heavy data (search results, PDF contents, API payloads) is stored in the Python/runtime variables and is never passed through the LLM context until a specific primitive actually neFeb 3, 2026 8:19 PM

Show HN: Nono – Kernel-enforced sandboxing for AI agentshttps://nono.shHey HNLuke here.I built nono and got it out quick then I expected, in response to the openclaw carnage, but its use is beyond openclaw.The problem: AI agents execute code on your machine. Prompt injections, hallucinations, or compromised tools can read ~/.ssh, exfiltrate credentials, or worse. Application-level sandboxes can be bypassed by the code they're sandboxing.I have been around security for a long old time now (i started something called sigstore a few years back) and have seen this pattern so many times before.The solution pitch: nono uses OS-level isolation that userspace can't escape:Linux: Landlock LSM (kernel 5.13+) macOS: Seatbelt (sandbox_init) After sandbox + exec(), there's no syscall to expand permissions. The kernel says no.What it does:nono run --read ./src --allow ./output -- cargo build nono run --profile claude-code -- claude nono run --allow . --net-block -- npm install nono run --secrets api_key -- ./my-agentFilesystem: read/write/allow per directory or file NeFeb 1, 2026 9:35 PM

Show HN: Beauty Arena – An Elo-based experiment to measure aestheticshttps://beautyarena.vercel.appHi HN,I built Beauty Arena to solve a data problem I've always found annoying: absolute rating scales (1-10) are terrible for subjective data. They suffer from massive inflation and inconsistent user baselines (one person's 7 is another person's 5).I wanted to test if pairwise comparison (1v1) could produce a cleaner, strictly relative dataset.Instead of asking "How beautiful is this person?", the system asks a simple question: "Who do you choose?". It uses a ranking system inspired by competitive games (Elo/Glicko) under the hood. As users vote, a global ranking emerges based on win/loss ratios against others rather than accumulated points.I'm curious about the "wisdom of the crowd" limits here. Does a pairwise sort actually converge on a clear consensus, or does it cycle indefinitely due to intransitive preferences (A > B, B > C, but C > A)?I'd love feedback on the ranking methodology and the overall UI.Dec 30, 2025 12:56 AM

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 beforeDec 16, 2025 7:55 PM

Show HN: Open-Source Visual Wiki Your Coding Agent Writes for Youhttps://www.npmjs.com/package/daviaHi HN,We’re Ruben, Afnan, and Theo. A couple of days ago we released the early repo for Davia and were surprised by how much feedback came in right away. We decided to turn it into a full open-source package you can run locally.Davia is designed for coding agents to generate an editable internal wiki for your project. It focuses on producing high-level internal documentation: the kind you often need to share with non-technical teammates or engineers onboarding onto a codebase. Writing this kind of documentation takes forever, diagrams are often missing, and most tools don’t let you edit everything locally or integrate smoothly with your workflow.Davia is fully open source. It produces an editable workspace: – Text lives in a Notion-like editor – Diagrams live on editable whiteboards – Everything runs locally and can be modified either in your IDE or in the workspaceOne thing people found especially interesting is that you can delegate the documentation to your IDE’s AI agent.

Anyone here work on Amazon Kindle iOS app?https://news.ycombinator.com/item?id=45651296The Kindle iPhone app has changed greatly, going from what felt like a quiet, efficient clone of the physical Kindle to a something bigger and less pleasant. After many years of happiness, to this user it now feels like an unstable, many-click portal to the larger platform. For example, instad of resuming where you were reading, it always goes back to "for you" page, with "your library" as an afterthought in the background. It literally takes 3 clicks to get back to the book you were reading, with various zoomed-in promotions. It uses lots of resources and often locks up.The question is: if you were an engineer who worked on this, are there some good reasons why it is this way? Am I missing something in Settings to get it back to be like it was?

Show HN: I just built a tool to turn any photo into pixel arthttps://www.phototopixel.art/Hey everyone,I'm excited to share a brand new side project I just finished building: phototopixel.art. It's a simple web tool that automatically converts any photo you upload into pixel art.I've always been a fan of the aesthetic of pixel art, but manually creating it is a tedious process. After trying out some existing tools and not being fully satisfied with the results, I decided to build my own. My goal was to create a fast and easy-to-use solution that consistently produces great-looking pixel art.Behind the Scenes The core of the tool uses a combination of color quantization and pixelation algorithms. When you upload a photo, the system analyzes its color data and reduces it to a limited palette, while simultaneously creating the iconic blocky look.One of the biggest challenges was fine-tuning the balance between preserving key details and achieving a genuine pixel art feel.
