Specific values of the Busy beaver function by Ciro Santilli 37 Updated +Created
The following things come to mind when you look into research in this area, especially the search for BB(5) which was hard but doable:
Automated theorem proving by halting problem reduction by Ciro Santilli 37 Updated +Created
If you can reduce a mathematical problem to the Halting problem of a specific turing machine, as in the case of a few machines of the Busy beaver scale, then using Turing machine deciders could serve as a method of automated theorem proving.
That feels like it could be an elegant proof method, as you reduce your problem to one of the most well studied representations that exists: a Turing machine.
However it also appears that certain problems cannot be reduced to a halting problem... OMG life sucks (or is awesome?): Section "Turing machine that halts if and only if Collatz conjecture is false".
Diffie-Hellman vs ECDH by Ciro Santilli 37 Updated +Created
ECDH has smaller keys. youtu.be/gAtBM06xwaw?t=634 mentions some interesting downsides:

Conjecture reduction to a halting problem by Ciro Santilli 37 Updated +Created
bbchallenge.org/story#what-is-known-about-bb lists some (all?) cool examples,
wiki.bbchallenge.org/wiki/Cryptids contains a larger list. In June 2024 it was discovered that BB(6) is hard.
Turing machine acceleration by Ciro Santilli 37 Updated +Created
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.
Zatoichi effect by Ciro Santilli 37 Updated +Created
This is a neologism by Ciro Santilli, it refers to the fact that Zatoichi was not fully blind, but extremely hard of sight, which makes him:
  • too capable for the blind people, who did not trust him
  • too incapable for non-blind people, who despised him
and metaphorically refers to similar situations where a person or group of people are in the middle of two groups and not part of either of them.
A related thing that comes to mind is Aum Shinrikyo's Prophet Shoko Asahara, who was semi blind, and would bully the fully blind people of his school for blind people.

webpack Sass import by Ciro Santilli 37 Updated +Created
This shows how to produce a minimized fully embedded CSS file with webpack from a sass:
cd webpack/sass
npm install
npm run build
xdg-open index.html
That example produces a dist/main.css file which is a compresesd combination of:

Verilator interactive example by Ciro Santilli 37 Updated +Created
The example under verilog/interactive showcases how to create a simple interactive visual Verilog example using Verilator and SDL.
https://raw.githubusercontent.com/cirosantilli/media/master/verilog-interactive.gif
You could e.g. expand such an example to create a simple (or complex) video game for example if you were insane enough. But please don't waste your time doing that, Ciro Santilli begs you.
Usage: install dependencies:
sudo apt install libsdl2-dev verilator
then run as either:
make run RUN=and2
make run RUN=move
Tested on Verilator 4.038, Ubuntu 22.04.
In those examples, the more interesting application specific logic is delegated to Verilog (e.g.: move game character on map), while boring timing and display matters can be handled by SDL and C++.
Vimium by Ciro Santilli 37 Updated +Created
Since you can't escape shitty browser GUIs and live in the command line, the next best thing you can do is to bring Vim bindings to your browser :-)
There is one major annoyance: you can't use ESC to leave the address bar focus, but using Tab as a workaround works:

IonQ by Ciro Santilli 37 Updated +Created
Video 2. Source. Co-founder of IonQ. Cool dude. Starts with basic background we already know now. Mentions that there is some relationship between atomic clocks and trapped ion quantum computers, which is interesting. Then he goes into turbo mode, and you get lost unless you're an expert! Video 1. "Quantum Simulation and Computation with Trapped Ions by Christopher Monroe (2021)" is perhaps a better watch.
