   OpenFreeMap – Open-Source Map Hosting▲848

   Hi HN, After 9 years of running my own OpenStreetMap tile server infra for MapHub (https://news.ycombinator.com/item?id=11389989), I've open-sourced it and launched OpenFreeMap. You can either self-host or use our public instance. Everything is open-source, including the full production setup — there’s no 'open-core' model here. Check out the repo (https://github.com/hyperknot/openfreemap). The map data comes from OpenStreetMap. I also provide weekly full planet downloads both in Btrfs and MBTiles formats. I aim to cover the running costs of the public…

   OpenStreetMap▲63

   Hey HN, jvaclavik here from OpenClimbing team! We are thrilled to release version 2.0 of our fully opensource/opendata climbing guide. Based on OpenStreetMap for map-data and Wikimedia Commons for images, we created a (hopefully) user-friendly app which completely uses these open databases, thus contributing data back to commons. We designed a simple and powerful notation for drawing climbing routes directly over the Wikimedia pictures: - https://wiki.openstreetmap.org/wiki/Key:wikimedia_commons:pa...

    I mapped HN's favorite books with GPT-4o▲285

    Hey HN! I love finding new books to read on here. I wanted to gather the most mentioned books and recreate the serendipity of physical browsing. I scraped 20k comments from HN threads related to reading, extracted the references and opinions using GPT-4o mini, and visualised their embeddings as a map. - OpenAI's embeddings were processed using UMAP and HDBSCAN. A direct 2D projection from the text embeddings didn't yield visually interesting results. Instead, HDBSCAN is first applied on a high-dimensional projection. Those clusters tend to correspond to different genres. The genre…

    Integer Map Data Structure▲91

    This project presents a new data structure for storing ordered integer maps. The proposed data structure is a compressive, cache-friendly, radix tree that has performance comparable to an unordered map (`std::unordered_map`) and is an order of magnitude faster than an ordered map (`std::map`).
