Firebase push id algorithm in Nim (aka Nimrod) (ref: https://www.firebase.com/blog/2015-02-11-firebase-unique-identifiers.html)
# Fancy ID generator that creates 20-character string identifiers with the following properties:
#
# 1. They're based on timestamp so that they sort *after* any existing ids.
# 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
# 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
# 4. They're monotonically increasing. Even if you generate more than one in the same timestamp, the
# latter ones will sort after the former ones. We do this by using the previous random bits
# but "incrementing" them by 1 (only in the case of a timestamp collision).

Hier ein Script, das ich für und mit @tekshrek gebaut habe um bei ihm eine externe Platte die an der #Synology NAS hängt "remote" vom Mac auswerfen zu können.
