I'm run an implementation of the [Nano ID](https://github.com/ai/nanoid) tiny, secure URL-friendly unique string ID generator via its [Nim implementation](https://github.com/icyphox/nanoid.nim).
|
|
|
|
The Nim script has hard coded:
|
|
|
|
* a [base 58 encoding](https://medium.com/concerning-pharo/understanding-base58-encoding-23e673e37ff6) alphabet to avoid similar looking letter and the use of non-alphanumeric characters.
|
|
* a 12 characters length output, which gives [a pretty low probability collision](https://zelark.github.io/nano-id-cc/) for the previous alphabet:
|
|
~616 years needed, in order to have a 1% probability of at least one collision at a speed of 1000 IDs per hour.
|
|
This is more than enough for our unique IDs applications, mostly in the documentation context,
|
|
which consists of hand crafted and/or programmatically produced notes ,
|
|
for example in data narratives, book(lets) and TiddlyWiki tiddlers of tens or hundreds of notes at most,
|
|
unevenly produced between hours, days and/or weeks..
|
|
|
|
The `External` tag is related on its dependency on other programming languages and frameworks,
|
|
though the dependency should be loaded by just loading a small binary with no dependencies.
