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…

I made an open source, MIT license Typescript library based on some of the latest research that generates prompt injection attacks. It is a super minimal/lightweight and designed to be super easy to use. Keen to hear your thoughts and please be responsible and only pen test systems where you have permission to pen test!

The discussion about what to use for database keys has come up a few times on HN. Integers or UUID, or maybe ULID/UUIDv7 with a time component. One that also comes up is prefixes (as used by Stripe, most famously). The biggest downside (imo) of the Stripe approach is that you either have to store them as strings, which isn't great, or strip/prepend in your API layer. So I made a new thing called UPID. It's most similar to ULID, as it includes a time-component (but with lower precision) and also encodes to a base32 alphabet. But it also includes a 20-bit prefix (allowing four…
