[erlang-questions] more random uniform

[Evgeny M]

1>  [erlang:spawn( fun() -> random:seed(X,Y,0), io:fwrite("~p ", 
[random:uniform(3)]) end ) || X<-lists:seq(1,10), Y<-lists:seq(1,10)]. 
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 

BUT (now() instead of X, y, 0)

2>  [erlang:spawn( fun() -> random:seed(now()), io:fwrite("~p ", 
[random:uniform(3)]) end ) || X<-lists:seq(1,10), Y<-lists:seq(1,10)]. 
1 3 3 2 3 1 2 1 2 3 1 3 1 2 1 3 3 1 1 3 2 1 2 1 3 1 3 2 3 2 3 2 3 1 2 3 2 3
