shortuuid.rb VS Ulid

At the risk of sounding stupid, I have no idea how bit-shifting and bitwise operators work, though I've worked in the field for over a decade and am now a Staff Engineer or whatever. There, I said it.

It's just something I haven't gotten around to reading yet. I suspect some code would be made clearer by it, but even when doing something similar I wound up using the math textbook was to do it even though I suspect the bit operators would be much faster.

Side note, an interesting thing to add to your benchmarks would be ULID https://github.com/Cysharp/Ulid

I’m using Postgres so I actually have it a little easier with its native sort order. I switched from NUlid that I was using from years back to this one [0], and the default .ToGuid() gets the desired sort order when used with Npgsql. Likewise though, no db-side generation of uuid - then again, isn’t that the benefit of using globally unique identifiers in the first place, to avoid needing to rely on the db to generate conflict-free identifiers, skipping HiLo or sequences, etc.

Anyway, nice to meet another .NET Ulid user in the wild!
