What it does
🚲 Every Citi Bike ride ever taken visualized on a map - freeman-jiang/bikemap.nyc
bikemap.nyc is a visualization of the entire history of Citi Bike , the largest bike-sharing system in the US. Each moving arrow represents a real bike ride, based on anonymized historical system data published by Lyft. There is no backend. The client uses DuckDB WASM to query parquet files using SQL directly from a CDN, downloading only the rows it needs via HTTP range requests. The raw system data spans 12 years and has significant inconsistencies, making it difficult to use directly. The processing pipeline cleans and normalizes the data into optimized parquet files. Create a .env file in apps/client and add your Mapbox token: NEXT_PUBLIC_MAPBOX_TOKEN=pk.xxx # Get one at…from github.com

Hey folks! A bit of background: I'm a software engineer by trade, but I'm currently on sabbatical doing a year-long working holiday in Australia. I love riding bikes but only had the most beginner-level knowledge of them before I found a job at a bike shop. This was a fun personal project to try to capture some of what I've learned so far, targeted at fellow beginners. It's going to be incomplete/lacking if you already have some bike knowledge, but I hope you all enjoyed it all the same. Please keep the feedback coming; it's late in Australia, but I want to make sure the bike info is at…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
