Description and purpose
|
|
=======================
|
|
The Everett interpretation of quantum mechanics ("Many Worlds") is that when
|
|
an interaction is made with an elementary wave function (such as an electron or
|
|
photon etc) the universe bifurcates.
|
|
ref: https://en.wikipedia.org/wiki/Many-worlds_interpretation
|
|
|
|
This happens naturally of course (just via radioactive decays in atoms of your
|
|
body there are about 5000 bifucations per second) but this component brings into
|
|
the mix "Free Will". By requesting a random number from the online source, which
|
|
is a beam-splitter based in Austrailia you are bifurcating the Universe deliberately
|
|
- that is, based on your Free Will.
|
|
You may or may not find that interesting, but nevertheless this component gives
|
|
you this ability (to "play God" with the Universe)
|
|
|
|
The random numbers returned are truly random (i.e. not pseudorandom via algorithm)
|
|
|
|
This package is a wrapper for querying a quantum number generator based in Austrailia.
|
|
|

|
Usage
|
|
=====
|
|
Open everettrandom.lpk and compile it.
|
|
In your application, include everettrandom as a required package
|
|
In a form unit:
|
|
In the Uses clause, add ueverettrandom
|
|
|
|
Code
|
|
====
|
|
Declare as a variable: MyEverett: TEverett;
|
|
In form Create: MyEverett := TEverett.Create(Self);
|
|
If you don't want to show a dialog whilst querying the server: MyEverett.ShowWaitDialog:=FALSE;
|
|
|
|
There are 3 functions that will retrieve a single integer:
|
|
// Fetch a single random number
|
|
function MyEverett.GetSingle8Bit: integer;
|
|
function MyEverett.GetSingle16Bit: integer;
|
|
function MyEverett.GetSingleHex: String;
|
|
|
|
// Array functions will put results into:
|
|
// (GetInteger8BitArray, GetInteger16BitArray) populates MyEverett.IntegerArray[0..Pred(ArraySize)]
|
|
// (GetHexArray) populates MyEverett.HexArray[0..Pred(ArraySize)]
|
|
// First set the properties:
|
|
// MyEverett.ArraySize (default=1)
|
|
//..and for Hex results
|
|
// MyEverett.HexSize (default=1) e.g. 1=00->FF 2=0000->FFFF 3=000000->FFFFFF etc.
|
|
// Result for array functions is TRUE(Success) or FALSE(failure)
|
|
function MyEverett.GetInteger8BitArray:Boolean;
|
|
function MyEverett.GetInteger16BitArray:Boolean;
|
|
function MyEverett.GetHexArray:Boolean;
