Random for Everyone: A Chaotic Guide

**Disclaimer** This guide is neither theoretically nor practically comprehensive. It covers only a limited subset of non-crypto PRNG algorithms found in the wild (LCGs and \(\mathbb{F}_2\)-linears in particular) and is just a random (pun intended) collection of notes, thoughts, and observations.
It also assumes that you’re familiar with modular arithmetics and linear algebra basics.

• In Part 1, we’ll review the general structure of PRNGs and the properties they have.
• Part 2 will cover LCGs and their special cases and notable properties.
• Part 3 will focus on XorShift-like generators in particular and \(\mathbb{F}_2\)-linear in general.
• And finally, in Part 4, we’ll discuss how to extend LCGs to achieve arbitrarily large period and \(k\)-dimensional equidistribution.

In this guide, I will use the following sources:

That's interesting. Every time I ask Google's #bard for random whole numbers, it gives me sawtooth-like ramping patterns. This is a great example for a stochastic simulation/numerical methods course -- uniformity, but not independence (i.e., bad random number generator).

Direct cow methane flaring. Literally cow flaring. Hey, why not connect a pipe & run it through a generator? 🤣 #rng h/t @RichardMeyerDC@twitter.com

RT @HowThingsWork_@twitter.com

Treating bloat in Cows.🐄💨 Bloat is a digestive disorder that results from the build up of excessive gas,which can can ultimately lead to death. This method of treatment helps the cow by releasing methane & the flames help the vet gauge the remaining gas left in the cow. 🐄

I'm working on an update to {doFuture} and a new %dofuture% infix operator:

y <- foreach(x = 1:3) %dofuture% {
something something
}

which removes the need for %dopar% (which btw comes with a few hidden bugs) and registerDoFuture().

%dofuture% will give you a consistent #futureverse behavior, just like when you use {future.apply} and {furrr}. Same for random number generation (RNG), which will be built-in, so no need for %dorng%

#dwarffortress one should never forget that #dwarffortress remains an #rng game where you have #luck and #probabilities on your side or against you.

I got my first #siege today without warning and at that time had no #squads or #weapons. So I made a pure #wrestling squad with random #dwards and just sent them into the siege.

My population dropped from 22 down to 8, but by some #luck, I won the #battle and the #war, and my fort lives on.

I basically three my B team at the crazy animal enemies and won. This will not be good for my #arrogance in the long run

I was taking a load off after having some physical therapy yesterday when um, my passive ability just dropped on a game I just bought to welcome the new year.

I broke probability in one night.

Jason Donenfeld, the creator of pass(1) and #Wireguard, and the current #Linux #RNG maintainer is debating whether or not to use an EFI non-volatile variable to store a random seed during shutdown that can be read an boot before userspace initializes.

Cool idea if it works.
