deterministic simulation

Will Wilson of FoundationDB explains how the team tested their distributed database using deterministic simulation. By running the whole system in a simulator with injected faults and reproducible seeds, they could find rare concurrency and network bugs.

George Hotz gives a SXSW 2019 talk on the idea that we live in a simulation and asks what actions would be available from inside it. He takes a hacker's view of whether it could be escaped.

An interview with Nick Bostrom at Oxford's Future of Humanity Institute presenting his simulation argument: at least one of three propositions about posthuman civilizations and ancestor simulations must be true.

Will Wilson explains autonomous testing: using deterministic simulation and fuzzing, building on FoundationDB's approach, to test software continuously. It sets out the ideas behind his later company Antithesis.

SpaceX engineers present at NVIDIA's GPU Technology Conference on a multi-physics code that simulates the full-scale Raptor methane engine. It covers GPU-based turbulent combustion modeling with adaptive grids and wavelet compression.

In this 2019 GDC session, Petri Purho of Nolla Games explains the technical side of Noita's physics engine, including scaling a falling-sand simulation to large continuous worlds and adding destructible rigid bodies. It also shows how the emergent physics drives the gameplay.

Jake Vanderplas's PyCon 2016 talk shows how sampling-based methods such as simulation, shuffling and bootstrapping make statistics intuitive. His pitch is that if you can write a for-loop, you can do statistics.

Terry Davis, author of TempleOS, demonstrates his SimStructure physics simulator and builds a PID controller using math from Numerical Recipes in C. The description notes PID controllers are used in everything from rockets to espresso machines.

A Vanity Fair Summit conversation between Elon Musk and Sam Altman, moderated by Andrew Ross Sorkin. They discuss the future of technology, including AI and the simulation hypothesis.

A /noclip interview with Tarn Adams of Bay 12 Games about Dwarf Fortress: where the ASCII simulation came from, how it works, and the plans for its Steam release. It includes his telling of the famous bug in which cats were poisoned by alcohol.

Cognitive scientist Donald Hoffman argues in this TED talk that evolution shaped perception to track fitness rather than truth. He uses evolutionary simulations and the Australian jewel beetle as examples.

Veritasium explains why many real-world systems follow power laws rather than normal distributions. It covers self-organized criticality, with simulations of sandpiles, magnetism and forest fires.

Huygens Optics explores the idea that space is a non-linear elastic medium, and uses simulations to show how wave energy might be confined locally into particle-like objects. It touches on inertia, the Schwinger limit and the vacuum as a medium.

AlphaPhoenix uses Monte Carlo simulation and annealing-style methods to draw North Carolina congressional district maps, both gerrymandered and fair. He focuses on the fascinating computational problem rather than the politics.

3Blue1Brown builds toy SIR models to simulate how an epidemic spreads and tests scenarios like social distancing, travel restrictions, central gathering places and quarantine. It was made during the early COVID-19 outbreak.

A 2018 GDC talk by NetherRealm's Michael Stallone on the engine changes, optimizations and tooling needed to roll back and re-simulate up to 8 frames in 16 ms in Mortal Kombat and Injustice 2. It is a deep dive into deterministic rollback netcode.

Michael Steil's 27c3 talk on reverse engineering the MOS 6502 from die shots into a transistor-level simulation, as in the Visual6502 project. It covers going from chip package to a digital model.

Rick Roderick's 1993 lecture on Baudrillard, the last in his series The Self Under Siege. It covers hyperreality, simulation and what Baudrillard calls fatal strategies.
