Show HN: Minimalist library to generate SVG views of scientific data https://ift.tt/LiJ19Te

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/2jEIZDe... 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/faWZEOL March 23, 2026 at 11:24PM

Show HN: MAGA or Not? Political alignment scores for people and companies https://ift.tt/z4Hg3yj

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, ...

Show HN: Revise – An AI Editor for Documents https://ift.tt/2Vczwbi

Show HN: Revise – An AI Editor for Documents I started building this 10 months ago, largely using agentic coding tools. I've stayed very involved in the code base and architecture, and have never moved faster in my life as a dev. The word processor engine and rendering layer are all built from scratch - the only 3rd party library I used was the excellent Y.js for the CRDT stack. Would love some feedback! https://revise.io March 22, 2026 at 06:58PM

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

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 cu...

Show HN: Termcraft – terminal-first 2D sandbox survival in Rust https://ift.tt/u5Z9wOD

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: EvalsHub: Your AI is failing in production and you don't know it https://ift.tt/YrZJS5C

Show HN: EvalsHub: Your AI is failing in production and you don't know it I was tired of stitching together Langfuse for tracing, promptfoo for red teaming and evals, and custom scripts for CI/CD. It was a mess so I built EvalsHub. EvalsHub does all of it in one place. Automatic production scoring, red teaming, prompt versioning, and CI/CD integration. Zero to full eval coverage in 30 minutes. Would love brutal feedback from anyone shipping AI in production. evalshub.ai https://www.evalshub.ai March 21, 2026 at 12:04AM
