*Description:*
In this video we demonstrate how to create pseudo random numbers with Arduino - with a useful twist.
This lesson was inspired by the following viewer question:
"How do I create Random Non-Consecutive numbers with Arduino.
P.S. These are the best tutorials that a complete idiot like you could ever make, thanks."
-Anonymous
*Let's overview exactly what we will talk about in todays episode:*
Talk about pseudo random numbers.
Identify the problem - using an Arduino sketch to demonstrate.
Discuss how we might solve the problem.
Write an Arduino sketch that solves the problem.
Review what we talked about.
*Pseudo Random Numbers*
Before we answer the viewer’s question it is important to talk about what a pseudo random number is.
A purely random number in the mathematical sense can't be predicted. The microcontroller that the Arduino uses (and for that case, most computers in general) can't really create pure random numbers.
What they create instead are called pseudo random numbers. These are numbers that appear to be randomly generated, but if studied over time a predictable pattern emerges.
The bottom line is that the random numbers we create with Arduino can be predicted.
Now there are clever ways to create pseudo random numbers that act like the real deal – you can learn about one method in our video tutorial talking all about random numbers – but for this discussion, let’s return to our viewers inquiry.
*Identify the Viewer’s Problem - use an Arduino sketch to demonstrate.*
Ok, so let's go back to the viewers question, he wants to generate random numbers, but he never wants the same number generated two times in a row.
Let's write an Arduino Sketch to make this clear.
//This sketch outputs pseudo random integers.
//A variable to hold pseudo random integers.
int randomInt = 0;
void setup() {
//Initiate serial communication.
Serial.begin(9600);
}//Close setup function
void loop() {
//Create a random number and assign it to the randomInt variable.
randomInt = random(0, 10);
//Send randomInt to the serial port for displaying on the serial monitor window.
Serial.print(randomInt);
}//Close loop function.
In the first block of code a variable that will hold the pseudo random integers is declared and initialized.
//A variable to hold pseudo random integers.
int randomInt = 0;
In the setup() function we begin serial communication in order to display the numbers we generate on a computer display.
void setup() {
//Initiate serial communication.
Serial.begin(9600);
}//Close setup function
In the loop() we create the random number with the Arduino random() function and assign the output to the variable we had just created. The random() function can take two arguments 1) the minimum value of the number we want generated 2) the maximum value we want generated.
//Create a random number and assign it to the randomInt variable.
randomInt = random(0, 10);
I will use 0 for the minimum, and 10 for the maximum.
Every time through the loop, a new random number will be assigned the randomInt variable.
Finally, the value of randomInt is sent over the serial port to be displayed in the serial monitor window.
//Send randomInt to the serial port for displaying on the serial monitor window.
Serial.print(randomInt);
If you upload this code and open the serial monitor you will see in some cases where the same number shows up two times in a row.
This is the problem. The viewer doesn't ever want the same number two times in a row.
*Discuss how we might solve the problem.*
So let's talk about how we might solve this problem. We know we need to generate a random number.
What if we create a variable to track the previous random number?
Then we could use a condition that says something like "If the previous random number is equal to the random number that was just generated, toss that number out the window, and create a different one.”
The final thing we would need to do is set the previous random number equal to the new random number, that way we keep updating our previous random number every time through the loop().
*Let’s Implement our solution in an Arduino Sketch.*
Copy and paste this code into your Arduino IDE. All you need is an Arduino board attached to your computer to make it work.

Randomness forms the basis of cryptography but computers are deterministic and therefore terrible for generating true randomness. In this episode we'll look at the FST-01, a $35 USB based true random number generator (TRNG) which harvests randomness from the environment. We'll flash the NeuG random number generator software onto the device using a serial programmer and a few wires. Then we'll plug it in, start it up and look at the random data it generates.

Mobile Computer Science Principles

Pseudorandom number generators are explained using John Von Neumann's middle squares method. Machines can't roll dice so they do a trick to generate randomness - they grow randomness. The middle squares method is explained from a computer science perspective using clocks as seeds. This is a clip from Art of the Problem episode #1. This clip features original music from Hannah Addario-Berry

One-photon based quantum technologies
In this lesson, you will discover two quantum technologies based on one photon sources. Quantum technologies allow one to achieve a goal in a way qualitatively different from a classical technology aiming at the same goal. For instance, quantum cryptography is immune to progress in computers power, while many classical cryptography methods can in principle be broken when we have more powerful computers. Similarly, quantum random number generators yield true random numbers, while classical random number generators only produce pseudo-random numbers, which might be guessed by somebody else than the user. This lesson is also an opportunity to learn two important concepts in quantum information: (i) qubits based on photon polarization; (ii) the celebrated no-cloning theorem, at the root of the security of quantum cryptography.
Learning Objectives
• Apply your knowledge about the behavior of a single photon on a beam splitter to quantum random number generators.
• Understand the no-cloning theorem
• Understand and remember the properties of q qubit
This course gives you access to basic tools and concepts to understand research articles and books on modern quantum optics. You will learn about quantization of light, formalism to describe quantum states of light without any classical analogue, and observables allowing one to demonstrate typical quantum properties of these states. These tools will be applied to the emblematic case of a one-photon wave packet, which behaves both as a particle and a wave. Wave-particle duality is a great quantum mystery in the words of Richard Feynman. You will be able to fully appreciate real experiments demonstrating wave-particle duality for a single photon, and applications to quantum technologies based on single photon sources, which are now commercially available. The tools presented in this course will be widely used in our second quantum optics course, which will present more advanced topics such as entanglement, interaction of quantized light with matter, squeezed light, etc... So if you have a good knowledge in basic quantum mechanics and classical electromagnetism, but always wanted to know: • how to go from classical electromagnetism to quantized radiation, • how the concept of photon emerges, • how a unified formalism is able to describe apparently contradictory behaviors observed in quantum optics labs, • how creative physicists and engineers have invented totally new technologies based on quantum properties of light, then this course is for you.

EXERCISES:
1. Modify the function to pass the current time into the random number seed and verify that a new sequence is always produced.
2. Create a pseudorandom number generator that generates only 1's and 0's, false and true values.
3. How would the difference in probabilities be between outputs if there were only 2^8 input values and 100 output values? What about if there were 2^8 input values and 128 output values?

What is PSEUDORANDOM NUMBER GENERATOR? What does PSEUDORANDOM NUMBER GENERATOR mean? PSEUDORANDOM NUMBER GENERATOR meaning - PSEUDORANDOM NUMBER GENERATOR definition - PSEUDORANDOM NUMBER GENERATOR explanation.
Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license.
A pseudorandom number generator (PRNG), also known as a deterministic random bit generator (DRBG), is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers. The PRNG-generated sequence is not truly random, because it is completely determined by a relatively small set of initial values, called the PRNG's seed (which may include truly random values). Although sequences that are closer to truly random can be generated using hardware random number generators, pseudorandom number generators are important in practice for their speed in number generation and their reproducibility.
PRNGs are central in applications such as simulations (e.g. for the Monte Carlo method), electronic games (e.g. for procedural generation), and cryptography. Cryptographic applications require the output not to be predictable from earlier outputs, and more elaborate algorithms, which do not inherit the linearity of simpler PRNGs, are needed.
Good statistical properties are a central requirement for the output of a PRNG. In general, careful mathematical analysis is required to have any confidence that a PRNG generates numbers that are sufficiently close to random to suit the intended use. John von Neumann cautioned about the misinterpretation of a PRNG as a truly random generator, and joked that "Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin."
A PRNG can be started from an arbitrary initial state using a seed state. It will always produce the same sequence when initialized with that state. The period of a PRNG is defined thus: the maximum, over all starting states, of the length of the repetition-free prefix of the sequence. The period is bounded by the number of the states, usually measured in bits. However, since the length of the period potentially doubles with each bit of "state" added, it is easy to build PRNGs with periods long enough for many practical applications.
If a PRNG's internal state contains n bits, its period can be no longer than 2n results, and may be much shorter. For some PRNGs, the period length can be calculated without walking through the whole period. Linear Feedback Shift Registers (LFSRs) are usually chosen to have periods of exactly 2n-1. Linear congruential generators have periods that can be calculated by factoring. Although PRNGs will repeat their results after they reach the end of their period, a repeated result does not imply that the end of the period has been reached, since its internal state may be larger than its output; this is particularly obvious with PRNGs with a one-bit output.
Most PRNG algorithms produce sequences which are uniformly distributed by any of several tests. It is an open question, and one central to the theory and practice of cryptography, whether there is any way to distinguish the output of a high-quality PRNG from a truly random sequence, knowing the algorithms used, but not the state with which it was initialized. The security of most cryptographic algorithms and protocols using PRNGs is based on the assumption that it is infeasible to distinguish use of a suitable PRNG from use of a truly random sequence. The simplest examples of this dependency are stream ciphers, which (most often) work by exclusive or-ing the plaintext of a message with the output of a PRNG, producing ciphertext. The design of cryptographically adequate PRNGs is extremely difficult, because they must meet additional criteria (see below). The size of its period is an important factor in the cryptographic suitability of a PRNG, but not the only one.
A PRNG suitable for cryptographic applications is called a cryptographically secure PRNG (CSPRNG). A requirement for a CSPRNG is that an adversary not knowing the seed has only negligible advantage in distinguishing the generator's output sequence from a random sequence. In other words, while a PRNG is only required to pass certain statistical tests, a CSPRNG must pass all statistical tests that are restricted to polynomial time in the size of the seed. Though a proof of this property is beyond the current state of the art of computational complexity theory, strong evidence may be provided by reducing the CSPRNG to a problem that is assumed to be hard, such as integer factorization. In general, years of review may be required before an algorithm can be certified as a CSPRNG.

https://za.pycon.org/talks/53-fast-random-number-generation-in-python-and-numpy/
A fast Random Number Generator (RNG) is key to doing Monte Carlo simulations, efficiently initialising machine learning models, shuffling long sequences of numbers and many tasks in scientific computing. CPython and NumPy use implementations of the Mersenne Twister RNG and rejection sampling to generate random numbers in an interval. The NumPy implementation trades more samples for cheaper division by a power of two. The implementation is very efficient when the random interval is a power of two, but on average generate many more samples compared to the GNU C or Java algorithms. The Python RNG uses an algorithm similar to GNU C.
A recent paper by Daniel Lemire (https://arxiv.org/abs/1805.10941) discusses an efficient division light method to generate uniform random numbers in an interval. This method is apparently used in the Go language. On 64-bit platforms there are also fast alternative RNGs that perform comparatively on statistical examinations passing tests like BigCrush. The splitmix64 (part of the standard Java API) and lehmer64 RNGs, for example, require approximately 1.5 cycles to generate 32 random bits (without using SIMD) while the 32-bit Mersenne Twister requires approximately 10 cycles per 32 bits.
This talk will discuss the inclusion of Lemire's method in NumPy as an alternative to the current rejection sampling implementation. My implementation results in a 2x - 3x improvement in the performance of generating a sequence of random numbers. Using splitmix64 or lehmer64 RNGs in NumPy instead of the Mersenne Twister results in a further 2x performance improvement.
The random module in Python does not do the rejection sampling in C like NumPy does. Much of the time to get a random number is therefore spent in the Python code. This talk will also discuss a fast random Python module that implements Lemire's method instead of the current rejection sampling, provides alternative RNGs and moves more of the code into C.
I'm considering doing pull requests for both the NumPy modification and the Python fast random module and will present a detailed analysis of the proposed modifications.

As advanced as computers have become they are still deterministic creatures at heart. With revelations by Edward Snowden surrounding Ellipitic Curve Cryptography and the discovery that the NSA and CIA were involved in the development of one of the RSA's psuedo-random number generators questions abound as to "What do those three letter agencies actually know and what can they do with this information?"
This presentation introduces the concept of Psuedo and Truly Random number generation, provides an overview of the different types of algorithms used in their generation, and then dives into a discussion about the Math and Theory behind how Prime Numbers and Elliptic Curves factor into the generation of psuedo-random numbers. An analysis of Dual_EC_DRBG is presented making it clear what the problem actually was and just how naughty the government has been! Best practices and gotchas are also outlined, a discussion regarding where randomness comes from in Perl as well as a few case studies are presented so that developers can protect themselves from common mistakes.
A background in Perl is not required and you are sure to find this presentation fun, entertaining, and just a bit random!

EVERYWHERE IN YOUR LIFE, EYL
Lately, as the frequency of threats to data and personal information has been increasing, the security of encryption keys has become crucially important for the perfect security in all areas of information and communication industry.
Encryption keys are composed of random numbers that should be impossible to decipher nor predict.
Existing Pseudo-random number imitates perfect random number with its generated values from an algorithm that is predictable and vulnerable to hacking.
However, EYL will provide perfect random numbers with the world's first encryption technology that utilizes Quantum-random number generator.
Since Quantum-random number generator has a mechanism of producing random numbers from detecting the particles emitted randomly and naturally from the radioactive isotopes.
EYL provides the perfect encryption keys that even the best hacker cannot even break.
As the number of IoT devices is growing exponentially with threatening security risks in reality
EYL will provide the perfect security through the encryption technology utilizing quantum-random numbers.
In the future, EYL's QRNG, smaller in size with stronger security, will protect your daily lives.
QUANTUM SECURITY WILL BE RIGHT IN YOUR POCKET

Need a Science Fair project? Here is how to make your own Dice Eliminator.
In Memoriam of Reuben Rowan (ElectronTeacher) whose human clock stopped recently, I present this video in his honor. Reuben gave me a gift a couple of years back of a Weller Soldering station. I use it quite often and used it to make my own design, simple Analog Random Number generator. It can be used to Randomly pick numbers from 1 to 12, just like dice. For simple dice games, this can be played faster and is a lot of fun. Using 2 different switches, the user can choose how he wants the unit to pick the number. Great for Monopoly and other Dice controlled games. I think building something like this is good for the mind and may get you an A on your next science project!
Good luck to you all and Happy Trails to you, Reuben.

With the above announcement by Bitcoin Superstore via their twitter handle, users can almost in an instant complete settlements with XRP while purchasing from different retail outlets. These outlets being the leading ones like eBay, Amazon and others. If you choose to go for this option remember that XRP in the past has given out results of being cheap for both the merchant offering to accept the token and the user. Or, even shorter, build a massive, level playing field in which assets can compete to bridge payments, then try to make XRP a winner on that playing field. This is an ambitious, maybe even crazy, plan. But Ripple has raised tens of millions of dollars, has over a hundred full time employees, and our successes to date speak for themselves. That is, of course, no guarantee of success.
