Why do you always have something to "complain" about?

I am sorry you feel that way.

Enjoy the software, it is cool

Not really (in my opinion).

and not so boring like using dev/urandom.

Also, likely not as good a 'randomness' generator either.

Or better instead of "complaining" do something creative, crypto wise
and show it to us too.

Ok, here's a simple random number generator using /dev/urandom:

    #!/usr/bin/tclsh

    set fd [open /dev/urandom {RDONLY BINARY}]
    binary scan [read $fd 16] ww hi lo
    close $fd

    puts "Your 128-bit random number is: [expr {abs($hi)*2^64 + abs($lo)}]"

Four sample runs:

    ~$ ./random.tcl
    Your 128-bit random number is: 12845925169244013330
    ~$ ./random.tcl
    Your 128-bit random number is: 12267131317558982811
    ~$ ./random.tcl
    Your 128-bit random number is: 10434877321040400260
    ~$ ./random.tcl
    Your 128-bit random number is: 16618556391581443091
