HeimdallFeb 2026 · heimdallspace.com · ▲126Hey HN, We built Heimdall (heimdallspace.com) because the existing tools for space situational awareness are genuinely painful to use: clunky interfaces, fragmented data sources, slow rendering. The ones that aren't are locked behind enterprise solutions. We thought the foundation of this should be open and accessible. The goal is a satellite observability platform: one place that gives operators complete, real-time insight into their assets and the orbital environment around them. Today's release is the foundation—aggregating and rendering the full public space catalog (30,000+ objects) in…

Talanoa▲345Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
