Turing machine acceleration refers to using high level understanding of specific properties of specific Turing machines to be able to simulate them much fatser than naively running the simulation as usual.

Acceleration allows one to use simulation to find infinite loops that might be very long, and would not be otherwise spotted without acceleration.

This is for example the case of www.sligocki.com/2023/03/13/skelet-1-infinite.html proof of Skelet machine #1.

Project trying to compute BB(5) once and for all. Notably it has better presentation and organization than any other previous effort, and appears to have grouped everyone who cares about the topic as of the early 2020s.

Very cool initiative!

By 2023, they had basically decided every machine: discuss.bbchallenge.org/t/the-30-to-34-ctl-holdouts-from-bb-5/141

In June 2024 they felt that they had verified the result after a full Coq proof was published: So now onto BB(6) I guess.

This notation is cool as it gives the spin quantum number, which is important e.g. when talking about hyperfine structure.

But it is a bit crap that the spin is not given simply as $\pm 1/2$ but rather mixes up both the azimuthal quantum number and spin. What is the reason?

TODO purpose? The transcripts are interspersed with developers likely voting for project leadership, and commenting on Gavin.

TODO find original discussion location, these are almost certainly from one of the Bitcoin IRC channels.

Part of the goal of this dump is that the Bitcoin developers have a policy of not allowing logging on their talk channel, and this released it all to the blockchain forever where it cannot be deleted. These might just be more of protests against larger block sizes.

Sometimes you just know that your existence will be remembered for a singular reason. Better than not being remembered at all perhaps.
