Hi!

I'm using the random-integer function, but it would seem that it always give the
same set of results after each execution... I then guessed I had to set the
random seed, somehow but I couldn't figure out the way to do it...

I tried something like:

(set! default-random-source (make-random-source))
(random-source-randomize! default-random-source)
(pp (random-integer 10))
(pp (random-integer 10))
(pp (random-integer 10))

And tried to run it multiple times and I still get the same answer each time I
run this simple program... :(

What should be done to make this random? Shouldn't be that the
default-random-source produce different random integers at each program launch??

Thanks!

David
