Get latest replies to an HN user2022 · github.com · ▲42Hi HN, I hacked a simple service for gathering HN replies and organizing them by the parent's username. The main idea is to be able to efficiently get the latest replies to an HN user. For example, you can use this service to send yourself notifications when some replies to you on HN. The service queries the official HN API and can be self-hosted. It is basically ~30 lines of Bash script. I made this mostly for educational purposes -- thought you might find it useful for something. Cheers! Edit: for example, here are the latest replies to me [0]. It includes only recent replies, since I…

I measured the half-life of 41,301 Show HN launches. It's 7 hoursJul 2026 · jonno.nz · ▲37I scraped every Show HN from the last 12 months (41,301 posts) plus the full comment tree of every launch with 10+ comments, ~100k comment timestamps, all from the Algolia HN API. The median launch gets 2 points and 0 comments. For launches that do get traction, half the comments they'll ever get arrive within 7.2 hours and 90% within 26, and the top decile decays on the same clock as everyone else. Vote timestamps aren't public, so comment timing is the attention proxy; caveats are in the post. Everything reproduces from the repo with one command…

Talanoa▲346Hi 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…
