Products that do what MyUUIDshop, Generate UUIDs and never worry about duplicates does
In response to some recent discussion here and on X about a company having an in house uuid microservice and team dedicated to it. At first that was made fun of, but further discussion revealed in fact sometimes uuids can collide due to improper entropy seeding most likely. In order to ensure that UUIDs are unique, we store each generation in a database, then check new generations against it to ensure they are not previously generated. As well, there is an API through which you can check if a UUID is present in the database. Paid options available for heavy use. Enjoy!

I 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…

An experiment with maze generation, started off in Rust, then ported to js to make it a web-app. The algorithm, code and setup aims to make it simple - and as always, simple turned out hard ;). The "about" dialog has some more information on choices made, tech used, inspiration and backgrounds. Most important, for a tech crowd, I guess is: - it uses p5.js - I generally prefer just vanilla js and canvas for my generative art projects, but here I wanted to focus on the outcome, not the tooling. - uses seedrandom with the name of you and your valentine as seed. So a unique, but reproducible…

Hey HN! I've been building random tools whenever I needed them over the past few months, and now I have 177 of them. Started because I was tired of sketchy converter sites with 10 ads, so I just... made my own. Some highlights for the dev crowd: Developer tools: - UUID Generator (v1/v4/v7, bulk generation): https://calcbin.com/tools/uuid-generator - JWT Generator & Decoder: https://calcbin.com/tools/jwt-generator - JSON Formatter/Validator: https://calcbin.com/tools/json-formatter - Cron Expression Generator (with…
