Show HN: I measured the half-life of 41,301 Show HN launches. It's 7 hours
https://jonno.nz/posts/your-show-hn-dies-in-7-hours/
I 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...

LocalChannels
I wanted to explore a few technical areas, particularly packaging with Homebrew and using Rust as a CLI tool. Additionally, I am eager to give back to a community that has brought me joy over the past 10 years.
So, to be frank (though that's not my name), I grew tired of paying for ngrok for a basic use case: routing public -> local tunneling during development, with a persistent configuration I could start and stop as required.
LocalChannels is about the millionth public to local tunnel tool posted here. It's not groundbreaking; it uses SSE to route the requests to your local machine.
The platform is limited to 1000 "tenants" to maintain performance, and up to three persistent channels per tenant - so once it's full, it's full. I hope someone finds it useful :)
