Show HN: Satellite imagery object detection using text prompts https://ift.tt/DFYdS5K

Show HN: Satellite imagery object detection using text prompts I built a browser-based tool for detecting objects in satellite imagery using vision-language models (VLMs). You draw a polygon on the map and enter a text prompt such as "swimming pools", "oil tanks", or "buses". The system scans the selected area tile-by-tile and returns detections projected back onto the map as GeoJSON. Pipeline: select area and zoom level, split the region into mercantile tiles, run each tile with the prompt through a VLM, convert predicted bounding boxes to geographic coordinates (WGS84), and render the results back on the map. It works reasonably well for distinct structures in a zero-shot setting. occluded objects are still better handled by specialized detectors like YOLO models. There is a public demo and no login required. I am mainly interested in feedback on detection quality, performance tradeoffs between VLMs and specialized detectors, and potential real-world use...

Show HN: Agentic Data Analysis with Claude Code https://ift.tt/bXINaLg

Show HN: Agentic Data Analysis with Claude Code Hey HN, as a former data analyst, I’ve been tooling around trying to get agents to do my old job. The result is this system that gets you maybe 80% of the way there. I think this is a good data point for what the current frontier models are capable of and where they are still lacking (in this case — hypothesis generation and general data intuition). Some initial learnings: - Generating web app-based reports goes much better if there are explicit templates/pre-defined components for the model to use. - Claude can “heal” broken charts if you give it access to chart images and run a separate QA loop. Would either feedback from the community or to hear from others that have tried similar things! https://ift.tt/CKlfiA7 March 10, 2026 at 11:44PM

Show HN: DenchClaw – Local CRM on Top of OpenClaw https://ift.tt/rH1Ty5W

Show HN: DenchClaw – Local CRM on Top of OpenClaw Hi everyone, I am Kumar, co-founder of Dench ( https://denchclaw.com ). We were part of YC S24, an agentic workflow company that previously worked with sales floors automating niche enterprise tasks such as outbound calling, legal intake, etc. Building consumer / power-user software always gave me more joy than FDEing into an enterprise. It did not give me joy to manually add AI tools to a cloud harness for every small new thing, at least not as much as completely local software that is open source and has all the powers of OpenClaw (I can now talk to my CRM on Telegram!). A week ago, we launched Ironclaw, an Open Source OpenClaw CRM Framework ( https://ift.tt/xkcYJVK ) but people confused us with NearAI’s Ironclaw, so we changed our name to DenchClaw ( https://denchclaw.com ). OpenClaw today feels like early React: the primitive is incredibly powerful, but the patterns are still forming, and everyone is piecing together their own way t...

Show HN: Skir – A schema language I built after 15 years of Protobuf friction Why I built Skir: https://ift.tt/WbyDcpS... Quick start: npx skir init All the config lives in one YML file.

Show HN: Astro MD Editor – Schema-aware editor for Astro content collections https://ift.tt/MrTCSgj

Show HN: Astro MD Editor – Schema-aware editor for Astro content collections I built this for my own Astro projects where I got tired of hand-editing YAML frontmatter and switching between files. astro-md-editor reads your collection schemas and gives you a local editor UI with typed frontmatter controls (including image/color/icon pickers) alongside a markdown/MDX editor. Run it with: npx astro-md-editor Would love feedback on schema edge cases or missing field types. https://ift.tt/jbkmTY5 March 8, 2026 at 11:44PM

Show HN: I built a simple book tracker because I kept buying books I owned https://ift.tt/IFanU5m

Show HN: I built a simple book tracker because I kept buying books I owned I'm Maureen, a senior and self-taught developer. I love browsing second-hand book markets but kept coming home with books I already owned. I couldn't find a simple enough app to track my library — everything required an account, had ads, or pushed a subscription. So I built one myself. SeniorEase Library (Android): scan an ISBN, book is added instantly. No account, no ads, one-time €2.99. First 10 books free. Would love any feedback! https://ift.tt/JZTs2ci March 8, 2026 at 11:17PM
