What it does
This API takes a latitude and longitude and gives back the time zone that the location is in. Based on Cloudflare Edge infrastructure, this API is highly performant and low latency from anywhere in the world.
Built on Cloudflare Workers running on the Cloudflare Edge network, using GEOJSON time zone data. Everything for this API is hosted by Cloudflare. Using Pages, Workers and KV store, the webpage and API use as much as possible from Cloudflare's worldwide infrastructure to minimise latency. Cloudflare's Edge nodes exist on almost every continent (sorry Antarticans!), so the latency because you and the time zone results are purely the time to calculate the result and your network.

Talanoa▲341Hi 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…

Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!
