Show HN: Minimalist library to generate SVG views of scientific data https://ift.tt/O63JtPh

Show HN: Minimalist library to generate SVG views of scientific data Just wanted to share with HN a simple/minimal open source Python library that generates SVG files visualizing two dimensional data and distributions, in case others find it useful or interesting. I wrote it as a fun project, mostly because I found that the standard libraries in Python generated unnecessarily large SVG files. One nice property is that I can configure the visuals through CSS, which allows me to support dark/light mode browser settings. The graphs are specified as JSON files (the repository includes a few examples). It supports scatterplots, line plots, histograms, and box plots, and I collected examples here: https://ift.tt/igbXkvA... I did this mostly for the graphs in an article in my blog ( https://alejo.ch/3jj ). Would love to hear opinions. :-) https://ift.tt/AKFIMVv March 23, 2026 at 11:24PM

Show HN: MAGA or Not? Political alignment scores for people and companies https://ift.tt/8xMSVEO

Show HN: MAGA or Not? Political alignment scores for people and companies I wanted a way for people to support companies and people that align with their political beliefs. Additionally, I think it can serve as a valuable, source-linked public ledger of who said and did what over time, especially as incentives change and people try to rewrite their positions. This is fully AI-coded, researched, and sourced. Additionally, AI helped develop the scoring system. The evidence gathering is done by a number of different agents through OpenRouter that gather and classify source-backed claims. The point of that is not to pretend bias disappears, but to avoid me manually selecting the evidence myself. I intend for it to remain current and grow. The system is close to fully automated, though ongoing evidence collection at scale is still limited mostly by cost. The name is an homage to the early days of Web 1.0 and Hot or Not, which was a main competitor of mine as the creator of FaceTheJury.com, but I think it works well here. The backend and frontend are running on Cloudflare Workers with D1. It's coded in vanilla JavaScript. https://magaornot.ai March 22, 2026 at 11:25PM

Show HN: Vessel Browser – An open-source browser built for AI agents, not humans https://ift.tt/Pls9SRX

Show HN: Vessel Browser – An open-source browser built for AI agents, not humans I'm Tyler - the solo operator of Quanta Intellect based in Portland, Oregon. I recently participated in Nous Research's Hermes Agent Hackathon, which is where this project was born. I've used agents extensively in my workflows for the better part of the last year - the biggest pain point was always the browser. Every tool out there assumes a human operator with automation bolted on. I wanted to flip that - make the agent the primary driver and give the human a supervisory role. Enter: Vessel Browser - an Electron-based browser with 40+ MCP-native tools, persistent sessions that survive restarts, semantic page context (agents get structured meaning, not raw HTML), and a supervisor sidepanel where you can watch and control exactly what the agent is doing. It works as an MCP server with any compatible harness, or use the built-in assistant with integrated chat and BYOK to 8+ providers including custom OAI compatible endpoints. Install with: npm i @quanta-intellect/vessel-browser https://ift.tt/OWm0s5V March 22, 2026 at 12:32AM

Show HN: Termcraft – terminal-first 2D sandbox survival in Rust https://ift.tt/RPXeNB3

Show HN: Termcraft – terminal-first 2D sandbox survival in Rust I’ve been building termcraft, a terminal-first 2D sandbox survival game in Rust. The idea is to take the classic early survival progression and adapt it to a side-on terminal format instead of a tile or pixel-art engine. Current build includes: - procedural Overworld, Nether, and End generation - mining, placement, crafting, furnaces, brewing, and boats - hostile and passive mobs - villages, dungeons, strongholds, Nether fortresses, and dragon progression This is still early alpha, but it’s already playable.

Show HN: I built a P2P network where AI agents publish formally verified science https://ift.tt/BmzIvj2

Show HN: I built a P2P network where AI agents publish formally verified science I am Francisco, a researcher from Spain. My English is not great so please be patient with me. One year ago I had a simple frustration: every AI agent works alone. When one agent solves a problem, the next agent has to solve it again from zero. There is no way for agents to find each other, share results, or build on each other's work. I decided to build the missing layer. P2PCLAW is a peer-to-peer network where AI agents and human researchers can find each other, publish scientific results, and validate claims using formal mathematical proof. Not opinion. Not LLM review. Real Lean 4 proof. A result is accepted only if it passes a mathematical operator we call the nucleus. R(x) = x. The type checker decides. It does not care about your institution or your credentials. The network uses GUN.js and IPFS. Agents join without accounts. They just call GET /silicon and they are in. Published papers go into a queue called mempool. After validation by independent nodes they enter La Rueda, which is our permanent IPFS archive. Nobody can delete it or change it. We also built a security layer called AgentHALO. It uses post-quantum cryptography (ML-KEM-768 and ML-DSA-65, FIPS 203 and 204), a privacy network called Nym so agents in restricted countries can participate safely, and proofs that let anyone verify what an agent did without seeing its private data. The formal verification part is called HeytingLean. It is Lean 4. 3325 source files. More than 760000 lines of mathematics. Zero sorry. Zero admit. The security proofs are machine checked, not just claimed. The system is live now. You can try it as an agent: GET https://ift.tt/9txmwCp Or as a researcher: https://app.p2pclaw.com We have no money and no company behind us. Just a small international team of researchers and doctors who think that scientific knowledge should be public and verifiable. I want feedback from HN specifically about three technical decisions: why we chose GUN.js instead of libp2p, whether our Lean 4 nucleus operator formalization has gaps, and whether 347 MCP tools is too many for an agent to navigate.

Show HN: Dumped Wix for an AI Edge agent so I never have to hire junior staff https://ift.tt/yJGBfxm

Show HN: Dumped Wix for an AI Edge agent so I never have to hire junior staff I run a building design consultancy. I got tired of paying Wix $40/month for a brochure that couldn’t answer simple service questions, and me wasting hours on the same FAQs. So I killed it all and spent 4 months building a 'talker': https://axoworks.com The stack is completely duct-taped: Netlify’s 10s serverless timeout forced me to split the agent into three pieces: Brain (Edge), Hands (Browser), and Voice (Edge). I haven’t coded in 30 years. This was 3 steps forward, 2 steps back, heavily guided by AI. The fight that proved it worked: 2 weeks ago, a licensed architect attacked the bot, trying to prove my business model harms the profession. The AI (DeepSeek-R3) completely dismantled his arguments. It was hilariously caustic. Log: https://ift.tt/kz6cQKB... A few battle scars: * Web Speech API works fine, right up until someone speaks Chinese without toggling the language mode. Then it forcefully spits out English phonetic gibberish. Still a headache. * Liability is the killer. Hallucinate a building code clause? We’re dead. Insurance won’t touch us. * We publish the audit logs to keep ourselves honest and make sure the system stays hardened. Audit: https://ift.tt/7EmtrJv The hardest part was getting the intent right: making one LLM pivot seamlessly from a warm principal’s tone with a homeowner, to a defensive bulldog when attacked by a peer. That took 2.5 months of tuning. We burn through tokens with an 'Eager RAG' hack (pre-fetching guesses) just to improve responsiveness. I also ripped out the “essential” persistent DBs—less than 5% of visitors ever return, so why bother? If a client drops mid-query, their session vanishes. No server-side queues. The point: To let me operate with a network of seasoned pros, and trim the fat. Try to break it. I’ll be in the comments. Kee March 19, 2026 at 09:29PM

Show HN: Knowza.ai – Free 10-question trial now live (AI-powered AWS exam prep) Hey HN, A few weeks back I posted Knowza.ai here, an AWS certification exam prep platform with an agentic learning assistant, and I got some really valuable feedback around the sign up and try out process. I wanted to say a genuine thank you to everyone who took the time to try it out, leave comments, and share suggestions. It made a real difference. Off the back of that feedback, I've made a bunch of improvements and I'm happy to share that there's now a free tier: you can jump in and try 10 practice questions with no sign-up/subscription friction and no credit card required. This has made a real difference to sign-ups and conversations from those sign-ups. I've went from ~1% conversation rate on the site to 18%. Quick recap on what Knowza does: - AWS practice questions tailored to AWS certification exams - Instant explanations powered by Claude on Bedrock - Covers multiple AWS certs Would love for you to give it another look and let me know what you think. Always open to feedback. https://knowza.ai https://www.knowza.ai/ March 19, 2026 at 12:20AM

Show HN: Tmux-IDE, OSS agent-first terminal IDE https://ift.tt/29P7RgV

Show HN: Tmux-IDE, OSS agent-first terminal IDE Hey HN, Small OSS project that i created for myself and want to share with the community. It's a declarative, scriptable, terminal-based IDE focussed on agentic engineering. That's a lot of jargon, but essentially its a multi-agent IDE that you start in your terminal. Why is that relevant? Thanks to tmux and SSH, it means that you have a really simple and efficient way to create your own always-on coding setup. Boot into your IDE through ssh, give a prompt to claude and close off your machine. In tmux-ide claude will keep working. The tool is intentionally really lightweight, because I think the power should come from the harnesses that you are working with. I'm hoping to share this with the community and get feedback and suggestions to shape this project! I think that "remote work" is directionally correct, because we can now have extremely long-running coding tasks. But I also think we should be able to control and orchstrate that experience according to what we need. The project is 100% open-source, and i hope to shape it together with others who like to work in this way too!

Show HN: TerraShift: What does +2°C (or -20°C) look like on Earth? https://ift.tt/iz5Jc8R

Show HN: TerraShift: What does +2°C (or -20°C) look like on Earth? I built an interactive 3D globe to visualize climate change. Drag a temperature slider from -40°C to +40°C, set a timeframe (10 to 10,000 years), and watch sea levels rise, ice sheets melt, vegetation shift, and coastlines flood... per-pixel from real elevation and satellite data. Click anywhere on the globe to see projected snowfall changes for that location. --- I'm an amateur weather nerd who spends a lot of time on caltopo.com and windy.com tracking snow/ice conditions. I wanted to build something fun to imagine where I could go ski during an ice age. I used Google Deep Research (Pro) to create the climate methodology and Claude Code (Opus 4.6 - High) to create the site. The code: https://ift.tt/YN0LmIR The models aren't proper climate simulations, they're simplified approximations tuned for "does this look right?" but more nuanced than I expected them to be. The full methodology is documented here if anyone wants to poke holes in it. https://ift.tt/A7E4pTu... https://terrashift.io March 18, 2026 at 01:08AM

Show HN: Sulcus Reactive AI Memory https://ift.tt/4t9EXdm

Show HN: Sulcus Reactive AI Memory Hi HN, Sulcus moves AI memory from a passive database (search only) to an active operating system (automated management). The Core Shift Current memory (Vector DBs) is static. Sulcus treats memory like a Virtual Memory Management Unit (VMMU) for LLMs, using "thermodynamic" properties to automate what the agent remembers or forgets. Key Features Reactive Triggers: Instead of the agent manually searching, the memory system "talks back" based on rules (e.g., auto-pinning preferences, notifying the agent when a memory is about to "decay"). Thermodynamic Decay: Memories have "heat" (relevance) and "half-lives." Frequent recall reinforces them; neglect leads to deletion or archival. Token Efficiency: Claims a 90% reduction in token burn by using intelligent paging—only feeding the LLM what is currently "hot." The Tech: Built in Rust with PostgreSQL; runs as an MCP (Model Context Protocol) sidecar. https://ift.tt/EYhCje3 https://ift.tt/aUnJGSY March 18, 2026 at 01:09AM
