Generate Version 7 UUID's for a Timestamp2025 · uuidv7.org · ▲20I use UUIDv7's in multiple places as an efficient index in Postgres. When querying this data I usually need to be able to query between a time range so wanted to have a quick way to generate a reference ID that I could use in a BETWEEN query. All the simple, fast tools I found online were focused on generating bulk ids or converting from an ID to a timestamp rather than the other way around, so I wrote one myself. For example if I wanted to find everything that happened between 2025-03-11T13:00:00.000Z and 2025-03-11T13:59:59.999Z I can type in the timestamp, select earliest (or latest) to…

Talanoa▲346Hi 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…

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
