Curiosity:

So, what ?

And so: asking PB to create a random RandomSeed when it shouldn't, I find that comical.

Huh?
Do you (always) get a weird result (like 1000)?
Not here on ARM Mac…
¿ random RandomSeed when it shouldn't ?

Doesn't make sense.

Random always starts at program start randomly

Pseudo random number generators (PRNGs) are state machines and the seed sets that state. You're setting the state randomly based on the previous random state. Some PRNG algorithms use the previous random number directly as state.

I heard many times about getting a Random "random SEED"… (e.g., to then extract lottery numbers…)
Stupid example I just invented now: you can use the luminosity of a flame being gently blown by a fan…
…or the movements of your mouse…
…or………

…Isn't that WEIRD?

………I find "randomness" to be very fascinating, like "infinity"…
I must stop here, or Olli will say I'm posting religious stuff

Even those things you mentioned are predictable if given enough information (and time). The only attribute you need to concern yourself with is whether they are random enough or if their randomness is comparable to the process you are trying to mimic.

Thanks Demivec; that's real Science! (Although much more limited than most ppl think)

PS: hmmm… are you really sure the flame luminosity is predictable? ;P

If you need real randomness use `CryptRandom()`. It creates cryptographic secure randomness.
