Sightline – Shodan-style search for real-world infra using OSM Data

Hi HN, I built *Sightline*, a Shodan-style search engine for *physical-world infrastructure*. Shodan makes it easy to explore exposed internet services. Sightline applies the same idea to the real world, using OpenStreetMap as the data source. You can search things like: * “telecom towers in karnataka” * “power plants near mumbai” * “data centers in paris france” or use structured queries: * `type:telecom operator:airtel region:karnataka` * `type:data_center operator:google` Sightline: * uses Overpass API for querying OSM features * uses Nominatim for resolving countries, regions, and cities…

In plain words

Sightline is a search engine for real-world infrastructure that works like Shodan but for physical locations. Built on OpenStreetMap data, it lets users find telecom towers, power plants, data centers, and other facilities by location or using structured queries with type and operator filters. It uses the Overpass API for querying and Nominatim for geographic resolution, with deterministic parsing rather than AI inference.

    Algorithmically finding the longest line of sight on EarthFeb 2026 · alltheviews.world · ▲412

    We're Tom and Ryan and we teamed up to build an algorithm with Rust and SIMD to exhaustively search for the longest line of sight on the planet. We can confirm that a previously speculated view between Pik Dankova in Kyrgyzstan and the Hindu Kush in China is indeed the longest, at 530km. We go into all the details at https://alltheviews.world And there's an interactive map with over 1 billion longest lines, covering the whole world at https://map.alltheviews.world Just click on any point and it'll load its longest line of sight. Some of you may remember Tom's post[1] from…

    Hi HN, I am Anubhav from Ramanlabs. We have been working on a native gui application to allow users to search any video data( mp4, mkv) or video streams (http/rtsp) using computer vision. Application is supposed to work like a video player which displays decoded frames and recognizes objects concurrently, making it an interactive experience. It works in super real-time and only expects a quad-core CPU with AVX2 instructions at minimum. Application is free to download (without any signup/account). We are only supporting WINDOWS for now [0]. Even though this is a binary application,…

    Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
