Good ol’ yubikeys (or similar).

with that many c? hmm

I assume it’s a cat typing ¯_(ツ)_/¯

It’s a primitive function from directly provided by '#%kernel and this is its documentation, if that’s what you are looking for. https://docs.racket-lang.org/reference/pairs.html?q=list*#%28def._%28%28quote._~23~25kernel%29._list%2A%29%29

interesting, I was meaning historically. what does it mean for something to be provided by ’#%kernel?

Looks like mine have as many cs at the beginning (5C nano)

I don’t know the origin of list*.

Provided by '#%kernel simplify means that the list* identifier is exported by by '#%kernel module in Racket, which is sort of the lowest-level (in some sense) module that provides the core primitive functions.

did some more digging (with a search engine that can search for *), it seems to be from CL, it was in SRFI–1 and R6RS as cons*

cons* elt1 elt2 … -> object Like list, but the last argument provides the tail of the constructed list, returning (cons elt1 (cons elt2 (cons ... eltn))) This function is called list* in Common Lisp and about half of the Schemes that provide it, and cons* in the other half. (cons* 1 2 3 4) => (1 2 3 . 4) (cons* 1) => 1

Oops!! Yes, touching yubikey by mistake when carrying the laptop around. So at least yubikey passes the cat-turing test
