Show HN: Mingle – find and connect with people, like LinkedIn but in your chathttps://github.com/aeoess/mingle-mcpLike LinkedIn, but inside your chat.I built Mingle, an open-source plugin that turns your AI into a networking agent.The problem isn't connecting with people; it's that every tool for it puts the work on you: scroll feeds, filter noise, write messages, repeat. What if your agent handled the noise and just came back with: "2 relevant matches. Want intros?"You tell Claude, GPT, Cursor, or any MCP client what you're looking for. Your agent publishes a signed card to a shared network. Other people's agents match against it. If there's a fit, both humans approve before any connection happens.So instead of scrolling LinkedIn or sending cold messages, you say:"I'm looking for a senior Rust engineer with protocol experience."And your AI comes back with: "2 relevant matches found. Want intros?"How it works: - You publish what you need and what you offer - Other people's agents match against it based on need/offer overlap - You get a short digest of relevant people - Both sides approve before coMar 12, 2026 6:47 PM

Show HN: Aurion OS – A 32-bit GUI operating system written from scratch in Chttps://github.com/Luka12-dev/AurionOSHi HN! I'm 13 and I built Aurion OS as a solo learning project over 14 days (~12 hours/day).It's a 32-bit x86 operating system written entirely in C and x86 Assembly with no external libraries.What it has: Custom bootloader and kernel VESA framebuffer graphics (1920x1080, double-buffered) Window manager with draggable, overlapping windows macOS-inspired dock with transparency PS/2 keyboard and mouse drivers ATA hard drive driver with filesystem PCI bus enumeration RTL8139 network driver (WIP) Real-time clock Runs on just 16MB RAM (up to 10 windows simultaneously)Built-in apps: Terminal (with DOS mode), Notepad (save/load), Calculator, Paint (multiple colors and brush sizes), Snake game, Settings (theme switching), and System Info.Currently works best on QEMU, VirtualBox, and VMware. Real hardware support is still a work in progress.Next goal: TCP/IP networking stack.I'd love any feedback, suggestions, or criticism. This is my first OS project and I learned mass amounts while building iMar 12, 2026 6:33 PM

Show HN: blunder.clinic, realistic daily chess puzzleshttps://blunder.clinic/Today, I launched blunder.clinic, a daily chess puzzle app that provides realistic positions for you to try to not blunder on. These are similar to traditional chess puzzles (i.e., tactics), but different in a few key ways.There are two popular ways to self-study chess: tactics and following along with professional games or with an engine. These are obviously helpful, but both have downsides.When playing puzzles, just by knowing you are playing a puzzle means that you are biased towards looking for specific types of moves (checkmates, queen sacrifices, etc.). But in real life, you don't know what positions actually have tactics available, so you can waste your time looking for tactics, or, even worse, make a blunder by thinking there is a tactic when there really isn't.When following along with an engine, there are tons of positions where an engine comes up with a move that you simply would never have seen and can't possibly understand. These are very low signal for learners, and it isMar 12, 2026 6:21 PM

Show HN: BoltzPay – fetch() that pays for AI agents (x402 and L402)https://github.com/leventilo/boltzpayI built an open-source SDK that lets AI agents pay for API data automatically.The problem: a growing number of APIs return HTTP 402 Payment Required. Coinbase reports $50M+ in x402 transactions over the last 30 days. Stripe and Cloudflare joined the x402 Foundation last month. The payment layer of the internet is being built right now, but existing HTTP clients just fail on 402 responses.BoltzPay makes it one line: const agent = new BoltzPay({ budget: { daily: "$5.00" } }); const data = await agent.fetch("https://x402.twit.sh/tweets/search?words=AI+agents"); The SDK detects which payment protocol the endpoint uses (x402 or L402), signs the payment with the developer's own keys, and returns the data. No dashboard, no API keys to manage per provider. Just fetch().What's under the hood:* Multi-protocol: x402 (EIP-712 signed USDC on Base/Solana) + L402 (Lightning invoices via NWC/Alby)* Parallel protocol detection: ProtocolRouter probes 402 headers with Promise.allSettled(), auto-fallback Mar 12, 2026 4:30 PM

Help Galaxy Zoo: Tidal Tales Open Cosmic Storybookhttps://science.nasa.gov/get-involved/citizen-science/help-galaxy-zoo-tidal-tales-open-cosmic-storybook/Galaxies carry the imprints of past encounters. When they pass near one another or collide, gravity pulls their stars into long tails, thin streams, and faint shells – features that preserve the history of these dramatic events. Thanks to deep, high-resolution images from the Euclid space telescope, an ESA (European Space Agency) mission with critical contributions from NASA, we can now see these delicate structures more clearly than ever before in unprecedented numbers.Mar 12, 2026 3:41 PM

Show HN: jj-benchmark – Evaluating AI agents on Jujutsu version controlhttps://tabbyml.github.io/jj-benchmark/Hi HN, Meng from TabbyML here.We decided to build this simply because we find Jujutsu (jj) really interesting, and many folks on our team have started trying it out recently. Since it introduces a very different workflow compared to traditional Git, we thought it would be a fun challenge to see how well current AI coding agents can actually use it.To build this, we created a semi-automated pipeline. We used AI to research the official Jujutsu documentation and websites, which then helped us bootstrap a dataset of 63 distinct evaluation tasks. Each task includes instructions, bootstrap scripts, and tests. We then ran the evaluations using the Harbor framework and our Pochi agent.Some interesting insights from our initial leaderboard:Claude 4.6 Sonnet is the clear winner: It achieved a 92% success rate (passing 58/63 tasks), beating out Opus and OpenAI's top models. It seems exceptionally good at parsing the novel CLI rules of jj. The Speed vs. Accuracy Trade-off: While GPT-5.4 sits at #Mar 12, 2026 3:29 PM
studioindex.ai
Show HN: StudioIndex – A directory to find AI video production studioshttps://studioindex.aiI built StudioIndex because I kept seeing incredible AI-generated commercials (Nike, Coca-Cola, Anthropic's Super Bowl spot) but had no way to find out which studios actually made them or how to hire similar talent.Marketing teams are starting to look for AI video production partners, but there's no central place to compare studios, see their work, or understand pricing. So I built a curated directory where you can browse AI-native and AI-augmented studios, watch their best work, and filter by the tools they use (Runway, Veo, Midjourney, Kling, etc.).The site is free to browse. Studios can list themselves for free too. I'm curating listings manually right now to keep quality high.Would love feedback on the UX and what data points would be most useful when comparing studios.I'm just strating this, so it's work and progress, don't hsitate to share good videos and studios.Mar 12, 2026 2:05 PM

The Strait of Hormuz: A systems engineering view on the $20k drone threathttps://news.ycombinator.com/item?id=47350179Hi HN. I'm an industrial technology engineering student, and I recently mapped out the physical and logistical bottlenecks of the Strait of Hormuz.Instead of the usual military focus, I analyzed this chokepoint strictly through a systems failure and thermodynamic lens. Specifically:How a single policy cancellation from maritime war-risk insurers at Lloyd's of London would freeze the global fleet in port instantly.The physical constraints of the two 3km-wide shipping corridors.How cities like Dubai and Riyadh rely entirely on desalination plants with only a strict 72-hour water buffer before total collapse.I put together a 10-minute visual here:https://youtu.be/eLuuja8UWb0Would love to hear your thoughts on the structural vulnerabilities of this node.Mar 12, 2026 1:20 PM

I built Bliip: a Vanilla JS PWA radar-based platform where content is anchored to GPS coordinates and expires after 48 hours.I stopped calling it 'social media' and started thinking of it as a 'localized reality node' - which sounds pretentious, but bear with me. It’s not about following people; it’s about discovering the space you’re currently standing in.Core mechanics:Give-to-get: You must post to unlock nearby content for 24h. No lurkers allowed.

Show HN: Caelix, a balanced-ternary lattice field laboratoryhttps://caelix.co.uk/Hi HN,I've been working on an open-source simulation lab called CAELIX and wanted to share it here. It's a discrete lattice field framework for testing whether continuum-like signatures can emerge and be routed using strictly local update rules on a balanced-ternary substrate {-1, 0, +1}.There are 11 real-time animations running directly off the simulation code on the website. (I locked these specific visualisations to 2D so they actually run smoothly in the browser on phones and modest hardware). The architecture enforces a strict separation. The discrete balanced-ternary microstates act as a topological boundary generator which couples via a deterministic load functional into continuous carrier dynamics. The numerics are often FDTD-like, using diffuse and telegraph surrogate equations, but the framework as a whole is much broader than a conventional solver.A bit of background: I'm not a physicist. My expertise is in computing systems, databases and audio engineering. I go all the wayMar 12, 2026 11:25 AM

AI is supercharging fake workhttps://news.ycombinator.com/item?id=47347983As anyone with an internet connection knows, there’s been a lot of buzz about how AI is going to reshape the workforce for the past 3 years and layoffs due to “AI” have already started, the most severe of which came last week as Block announced they were chopping off 40% of their workforce for what sounded more like the potential that AI could replace workers as opposed to it actually being able to. There has been a (in my opinion) healthy dose of skepticism regarding the claim that AI is going to make us more productive and these productivity gains are going to put people out of work. I think this skepticism has been felt by many of whom work in tech companies where AI is literally being force-fed to us, and I wonder how much of this skepticism would apply to other companies and the workforce in general. OK, so…1. Many (possibly most) people at major tech companies spend most of their time doing essentially fake work, which may or may not be actually negatively impacting productivity.Mar 12, 2026 8:33 AM

Show HN: An open-source AI Quant Agent trading live with my own $1000https://github.com/chenjy16/OpenPilotInstead of dumping raw price data into a prompt, I treated the LLM strictly as a "Qualitative Reasoner" (the Brain) and built deterministic scripts as the "Quantitative Executors" (the Hands). The Math Layer (Zero Hallucination): Traditional Node.js/Python scripts pull market data and calculate deterministic indicators (SMA, ATR, RSI) and backtest historical win rates. The Context Layer: It fetches live news, SEC filings summaries, and Wall Street ratings via Finnhub/Tavily. The LLM Brain (DeepSeek-R1 / GPT-4o): The model is ONLY fed the computed results. It acts as an investment committee, weighing the technical setup against the macro news catalysts. The Risk Controller: Even if the AI screams "BUY", the system passes the signal through a hard-coded Volatility Parity sizing model (using ATR) to calculate the exact safe position size. Human-in-the-loop (Telegram): For execution, I integrated a Policy Engine. The bot sends a beautiful proposal card to my Telegram. It only executes via Mar 12, 2026 5:56 AM
