Tripod ID

Distributable user-friendly id.

Examples

• 123 : shortest version
• 456-789 : default size, still user freindly and sufficient randomness (for personal data)
• abc-def-ghj : long version. alphabets except i, l and o are also valid

When I considering implementing IDs for users(not for internal system) to specify items, such as GitHub commit hashes or issue numbers, the following issues arose.

• Sequential numbers like Git issues are difficult to implement in distributes systems because collitions are unavoidable.
• Random number like UUID is too long for users
• Short random number like 7-digit commit hash seems good but is is not standardized specification.

So I decided to make my own ID specifications.
