Show HN: TierHive – Hourly-billed NAT VPS with private /24 subnets This idea has been floating in my head for about 10 years. Some of you might remember LowEndSpirit.com back before it became a forum, I started that. I've been obsessed with making tiny, cheap VPS actually useful ever since. TierHive is my attempt to make 128MB VPS great again :) It's a NAT VPS (KVM) platform with true hourly billing. Spin up a server, use it for 3 hours, delete it, pay for 3 hours. No monthly commitments, no minimums beyond a $5 top-up.

Show HN: bikemap.nyc – visualization of the entire history of Citi Bike Each moving arrow represents a real bike ride. There are 291 million rides in total, covering 12 years of history from June 2013 to December 2025, based on public data published by Lyft. If you've ever taken a Citi Bike ride before, you are included in this massive visualization! You can search for your ride using Cmd + K and your Citi Bike receipt, which should give you the time of your ride and start/end station. Some technical details: - No backend! Processed data is stored in parquet files on a CDN, and queried directly by DuckDB WASM - deck.gl w/ Mapbox for GPU-accelerated rendering of thousands of concurrent animated bikes - Web Workers decode polyline routes and do as much precomputation as possible off the main thread - Since only (start, end) station pairs are provided, routes are generated by querying OSRM for the shortest path between all 2,400+ station pairs Legend: - Blue = E-Bike - Purple = Classi...
