Show HN: DevIndex – Ranking 50k GitHub developers using a static JSON filehttps://news.ycombinator.com/item?id=47193729Hey HN,I’ve always been frustrated by the lack of an accurate ranking for top open-source contributors on GitHub. The available lists either cap out early or are highly localized, completely missing developers with tens or hundreds of thousands of contributions.So, I built DevIndex to rank the top 50,000 most active developers globally based on their lifetime contributions.From an engineering perspective, the constraint I imposed was: *No backend API.* I wanted to host this entirely on GitHub Pages for free, meaning the browser had to handle all 50,000 data-rich records directly.Here is how we made it work:1. *The Autonomous Data Factory (Backend):* Because GitHub's API has no "Lifetime Contributions" endpoint, we built a Node.js pipeline running on GitHub Actions. It uses a "Network Walker" spider to traverse the social graph (to break out of algorithmic filter bubbles) and an Updater that chunks GraphQL queries to prevent 502 timeouts. The pipeline continuously updates a single `userFeb 28, 2026 11:13 AM

Show HN: Stash – AI-powered self-hosted bookmark managerhttps://github.com/ayoub9360/stash-bookmarkI built Stash, a self-hosted bookmark manager that uses AI to automatically process your links.Paste a URL and it fetches the content, parses it, summarizes it, auto-assigns categories and tags, and generates a vector embedding for search.Search is hybrid — it combines pgvector cosine similarity (semantic) with PostgreSQL tsvector (keyword) and merges both with Reciprocal Rank Fusion. You can search in natural language ("articles about distributed systems tradeoffs") or with simple keywords.It's single-tenant by design: one password, no user accounts, no tracking. Your data stays on your machine.The project is MIT licensed don't hesitate to contribute. Some areas where help would be great: browser extension, bookmark import/exportGitHub: https://github.com/ayoub9360/stashHappy to answer questions about the architecture or the hybrid search approach.Feb 27, 2026 2:11 PM

Show HN: Context Harness – Local first context engine for AI toolshttps://github.com/parallax-labs/context-harnessContext Harness is a single Rust binary that gives AI tools like Cursor and Claude project-specific memory. It ingests docs, code, Jira tickets, Slack threads, and anything else into a local SQLite database, indexes them with FTS5 and optional vector embeddings, and exposes hybrid search via CLI and an MCP-compatible HTTP server.I built this because I kept hitting the same problem: AI tools are powerful but have no memory of my complex multi-repo project. They can't search our internal docs, past incidents, or architecture decisions. Cloud RAG services exist, but they're complex, expensive, and your data leaves your machine. I wanted something I could point at my sources and just run `ctx sync all`.Quick start: # Install (pre-built binaries available for macOS/Linux/Windows) cargo install --git https://github.com/parallax-labs/context-harness.git # Create config and initialize ctx init # Sync your data sources (filesystem, Git, S3, or Lua scripts) ctx sync all # Search from CLI ctx seaFeb 26, 2026 6:26 AM

Seedream 5.0 Lite API Pricing Breakdownhttps://news.ycombinator.com/item?id=47146196Seedream 5.0 Lite just dropped. Seedream 5.0 Lite just dropped. If you're curious about the most cost-effective way to run this in a production workflow, I put together a quick breakdown of the features and a price comparison across a few providers.1. Seedream 5.0 Lite Key Enhancements Here is what stands out in the 5.0 Lite update: - Stronger Feature Consistency: Noticeable jump in facial consistency and detail when using multi-image references. - Detail Preservation: It maintains natural skin tones and postures much better across batch outputs. - Precise Instruction Following: Handles complex camera angles and specific brush-style effects more reliably. - Multimodal Reasoning: You can feed it rough sketches or abstract logic, and it translates them into commercial-ready designs. - Visualizing Complex Data: Great for turning raw data or knowledge sets into clean visuals for presentations. - Broad Use Cases: Fast enough for marketing/E-commerce but high-quality enough for film/game preFeb 25, 2026 1:39 AM

Show HN: PaperBanana – Paste methodology text, get publication-ready diagramshttps://news.ycombinator.com/item?id=47132143I got tired of spending hours in PowerPoint and TikZ drawing methodology diagrams for my papers. So I built PaperBanana — you paste your Method section text, and it generates a publication-ready figure in about 2-3 minutes.How it works under the hood:1. A Retriever agent searches a curated database of real academic diagrams to find structurally similar references 2. A Planner agent reads your text and generates a detailed visual description (layout, components, connections, groupings) 3. A Stylist agent polishes the visual aesthetics without changing content 4. Then it enters an iterative loop: a Visualizer generates the image, and a Critic evaluates it and suggests revisions — this repeats 1-5 times (you choose)The key insight is that academic diagrams follow conventions — Transformer architectures, GAN pipelines, RLHF frameworks all have recognizable visual patterns. By retrieving relevant references first, the output is much closer to what you'd actually put in a paper vs. generic AFeb 24, 2026 2:34 AM

Show HN: Irpapers – Visual embeddings vs. OCR trade-offs in scientific PDFshttps://github.com/weaviate/query-agent-benchmarkingHey HN, we are releasing IRPAPERS to answer a highly pragmatic question: when building a RAG pipeline over PDFs, should you OCR the text or just embed the raw page images?Processing PDFs in production usually involves stringing together brittle OCR heuristics. While recent multimodal embeddings (like ColModernVBERT or ColPali) allow you to skip OCR entirely and retrieve directly from visual layouts, we wanted to measure if the computational overhead is actually worth the utility.The short answer: Transformer-based image pipelines won't be perfect for every use-case, but they fix exactly what OCR breaks.Here is what we found benchmarking 3,230 pages of dense scientific literature:Complementary Bottlenecks: Text representations (BM25 + dense vectors) are highly efficient for exact lexical constraints (e.g., finding a specific acronym like "HyDE"). Conversely, image embeddings shine on spatial architecture diagrams and t-SNE plots where OCR serialization just turns into structural garbageFeb 23, 2026 5:10 PM

Instance segmentation model that extracts 3D geometry from 2D floor planshttps://news.ycombinator.com/item?id=47092547Hey HN,I am an ML Engineer and a full-stack software engineer. For the past few weekends, I have been working on a pipeline to solve a PropTech problem: turning messy, highly occluded 2D floor plans into clean, structured data for 3D extrusion. Originally demoed for a firm hiring for the role.The Problem: If you try to use standard object detection (bounding boxes) or basic OCR (tested Qwen, DeepSeek) on architectural plans, it fails instantly. Walls intersect, doors swings and dimension lines heavily occlude the actual structures.The Stack & Architecture: I built an instance segmentation pipeline that relies strictly on pixel-perfect masking to pull the geometry.The Backbone: Swin Transformer + Detectron2.Model trained on 1024X1024 images, with RTX 4090Inference: Inference on CPUFeb 20, 2026 7:17 PM

Show HN: AFS – filesystem-native memory layer for AI agentshttps://news.ycombinator.com/item?id=47062802I've been building multi-agent AI pipelines and kept running into the same structural problem: agents are stateless by default. Every session restart discards everything they learned. In multi-agent systems it compounds — Agent-1 learns something Agent-2 will never know. I started calling it "agent amnesia." AFS is my attempt to fix this. The central architectural decision is unusual: your filesystem IS the memory layer. There's no separate database process to run, no cloud service to authenticate against. AFS stores memories as JSON files in a `.afs/` directory, with SQLite FTS5 for full-text search, HNSW indices for vector similarity, and msgpack-encoded graph edges for relationships. *Three-tier memory lifecycle (automatic)* Memories auto-migrate without explicit management: - Working memory (< 24h): raw observations, fast access, no compression- Episodic memory: full history with provenance, searchable - Semantic memory: auto-consolidated knowledge (scheduler synthesizes patterns fFeb 18, 2026 4:31 PM
