Superdeterminism appears to aspire to come up with a classical model that would explain quantum correlation. If successful it would render a quantum computer to be fancy, highly parallel, very expensive but still a classical one. A non-clas

Same thing: greedy algorithms. Mostly imposed by companies "living by algorithms".

Galois (finite) fields are very much relevant in error correction codes and cryptography. Any time you want to manipulate bytes (or words) as numbers which you can add/subtract and multiply/divide you end up learning about finite

It turns out there is a simple, though not trivial, conversion from Cauchy to Vandermonde, so all error correction techniques apply.

> Cauchy matrices are more foolproof, which is why I started with them. I always wanted to know but was afraid to ask. I see why people choose Cauchy for encoding: it's simple and fast ( more foolproof ? - that I don't see).

Don't confuse individual commands with the operating system, which is highly concurrent. I was very specific in my statement.

Concurrency = logical simultaneity. Parallelism = physical simultaneity. When the former is mapped to the latter we encounter scalability. Some examples: Unix commands (cp, grep, awk, sort) do not scale on multi-core systems due to total la

Not so fast :) Your own time would not "come to a halt and disappear", would it? If something travels with you at the same speed it would not get frozen in time. So, "everything that you would be seeing" is a bit too inc

Simulating the Mandelbrot set is also awfully computationally expensive. Unless you know the trick.
