New top story on Hacker News: Show HN: Weather Watching
Show HN: Weather Watching
16 by walz | 1 comments on Hacker News.
I was walking around New York last month during some light rain and noticed about half the people had umbrellas open. When the rain picked up a few minutes later, that number jumped closer to 80%. It got me thinking it'd be cool to track this somehow, so I built a website! I am taking a sidewalk livestream, feeding it into a YOLO model for people tracking, then sending a frame of each detected person to Gemini 2.0 Flash, which returns structured JSON about each person's clothing and if they're holding an umbrella. I also had fun making the site look like a TV weather channel. I showed some friends this project and someone mentioned how the legendary Tasks xkcd comic ( https://xkcd.com/1425 ) is out of date now. If you want to check whether a photo has birds in it (or if someone is holding an umbrella), you can just ask an inexpensive vision model for JSON.

New top story on Hacker News: Show HN: High End Color Quantizer
Show HN: High End Color Quantizer
9 by big-nacho | 0 comments on Hacker News.
This is a personal project I've been working on for a long time now. I stumbled upon the color quantization problem while doing something related for work. I then found an interesting paper for which I could find no implementations online, and the thing went from "let's implement this paper" to getting pretty obsessed with the whole thing. It's at an early, eaaaarly stage. There's a lot of work to be done, and it's a memory hog, but generally speaking works quite well, and the output is for the most part very high quality, so I'm happy to share it as beta.

New top story on Hacker News: Show HN: I built an OSINT tools directory
Show HN: I built an OSINT tools directory
15 by r00m101 | 4 comments on Hacker News.
I work on R00M 101, a Reddit-based OSINT profiler. While building it, I realized most open-source intelligence (OSINT) tools are scattered across GitHub, outdated blog posts, or random Discords. So I put together a public-facing directory of 100+ OSINT tools used by analysts, journalists, and security folks, free, filterable, and categorized by risk, platform, and use case. The idea was to make something useful and no-friction. Built with static HTML + SQL backend + a lot of caffeine. Would love feedback on how to improve the UX or tool curation. If anyone wants to contribute tools or help moderate, that’s also welcome. Thanks!
