#elisp
Function:
random &optional limitThis function returns a pseudo-random integer. Repeated calls return a
series of pseudo-random integers.
If limit is a positive integer, the value is chosen to be
nonnegative and less than limit . Otherwise, the value might be
any integer representable in Lisp, i.e., an integer between
most-negative-fixnum and most-positive-fixnum
(see Integer Basics).
If limit is t, it means to choose a new seed as if Emacs
were restarting.
If limit is a string, it means to choose a new seed based on the
string’s contents.

GNU Emacs Lisp Reference Manual: Random Numbersmake the sequence repeat, execute (random "") .
This sets the seed to a constant value for your particular Emacs
executable (though it may differ for other Emacs builds). You can use
other strings to choose various seed values.
