Parity violation by Ciro Santilli 40 Updated 2025-09-17
This is quite mind blowing. The laws of physics actually differentiate between particles and antiparticles moving in opposite directions!!!
Only the weak interaction however does it of the fundamental interactions.
Some historical remarks on Surely You're Joking, Mr. Feynman section "The 7 Percent Solution".
It gets worse of course with CP Violation.

Septuagint by Ciro Santilli 40 Updated 2025-07-16
It is fun to see that some New Testament sources cite this Greek version rather than more ancient ones because they or their listeners would not understand the other original languages.
Direct translation from oldest documents deemed reliable, originally in a mixture of Hebrew, Aramaic, and Greek. Interesting project.
This is notably opposed to the approach taken by many versions which were based on the Septuagint, which was a much earlier full-Greek translation.
With Falun Gong it's even more fun: the words of God Himself are will be copyrighted for a while after Li Hongzhi dies!!!
The example under verilog/interactive showcases how to create a simple interactive visual Verilog example using Verilator and SDL.

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 40 Updated 2025-07-16
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:
Banheiros da USP by Ciro Santilli 40 Updated 2025-07-16
Semi-comical student website to review the toilets of the University of São Paulo. Some of the toilets had a reputation for being terrible.
One is reminded of Crushbridge.
