Ship Clock
See which Show HN posts gain traction fastest
Ship Clock launched on March 28, 2026.
What it does
Ship Clock is a real-time velocity dashboard for Show HN posts. It fetches live data from the Hacker News API, computes points-per-hour for each Show HN submission, and ranks them by traction speed. Instead of scrolling through pages of posts, Ship Clock gives you one clear leaderboard: which launches are gaining momentum right now. It auto-refreshes every two minutes so you can watch trends develop.

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…

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…
