This card pertains to a resource available on the internet.
Another simple ID generator aimed at not blowing up B-Trees in databases like random numbers do.
A ULID is a 48-bit timestamp stored in the leftmost bits and combined with 80 bits of randomness.
Randomness is sampled only when a new milisecond is detected; all IDs created the same milisecond will have the same randomness. Instead the random number is incremented by one for each subsequent message.
Textual representations use Crockford's Base32 encoding.
// Assume that these calls occur within the same millisecond ulid() // 01BX5ZZKBKACTAV9WEVGEMMVRY ulid() // 01BX5ZZKBKACTAV9WEVGEMMVRZ ulid() // 01BX5ZZKBKACTAV9WEVGEMMVS0 ulid() // 01BX5ZZKBKACTAV9WEVGEMMVS1
