Animation of Hong-Ou-Mandel Effect on a silicon like structure by Quantum Light University of Sheffield (2014): www.youtube.com/watch?v=ld2r2IMt4vg No maths, but gives the result clear: the photons are always on the same side.

Ubuntu Updated 2025-07-16

Ciro Santilli's Linux distro of choice as of 2019.
It ain't perfect, but it's decent enough.
The greatest advantage of it being that it has the likely largest desktop user base, and therefore the highest likelihood that your problems are solved on Ask Ubuntu, and goes together with Ciro's philosophy that "people should do everything in the same way to factor stuff out", especially the open source losers.
Ciro considers that the killer flaw of Ubuntu, and most desktop distros of 2020, is that no one under the Sun knows how to build them fully from source: Linux distribution buildable from source. This is why Ciro based the Linux Kernel Module Cheat on Buildroot, see also: Linux distribution buildable from source.

Ubuntu 23.04 boot broken on kernel 6.2 Updated 2025-07-16
View more
Switching to the other installed kernel, 5.9 made boot work.
The solution on kernel 6.2 was:
sudo apt instal nvidia-driver-515
as per comments under: bugs.launchpad.net/ubuntu/+source/linux/+bug/2012559. This also made the nvidia driver work: Find GPU information in Ubuntu.
Previously I had:
nvidia-driver-510
and it blew up before reaching disk decryption.
I also tried:
nvidia-driver-525
but that broke in a different way:
Finished apport-autoreport.service - Process error reports when automatic reporting is enabled.
nvidia-modeset: ERROR: GPU:0: Idling display engine timed out: 0x0000947d:0:0:407

Software-based artificial life Updated 2025-07-16
View more
Some of the software-based artificial life simulators can be used as AI training game.
Ciro Santilli just always feels that what can be classified as "artificial life" simulators have too much focus on beating more continuous population mechanics, and lack the discrete elements which he feels could be important to AGI: Section "The missing link between continuous and discrete AI".
There is great interest in this direction of research however quite clearly.

Happens at startup without doing anything, and then keeps happening randomly infinitely many times... on a almost clean 24.04 ISO install on Dell Inspiron 15 3520... God how can it be so bad.
