  2. Just to see the big picture, what are the main differences between this and Snowflake, or ULID ( https://github.com/ulid/spec )?

  3. https://github.com/ulid/spec isn't timeflake, but is a good spec, and there are implementations in multiple languages. there are 2 listed for js. https://github.com/aarondcohen/id128 and https://github.com/ulid/javascript

  4. There’s a spec called ULID that’s pretty much this with default base32 encoding https://github.com/ulid/spec I’ve also worked on a UUID-ULID bridge for Go https://github.com/sudhirj/uulid.go And seeing as this is just 128 bits it’s quite…

  9. I've been using ULID as an alternative to UUIDs, e.g.: https://github.com/ulid/spec I've found ULID to be great for my purposes. Wonder if anyone else has tried using them too?

  14. ULID - https://github.com/ulid/spec it's like 48bits of control and 80 bits of power packed into 128bits of fun!!
