Simulation of the time-dependent Schrodinger equation (JavaScript Animation) by Coding Physics (2019)
Source.
Source code: github.com/CodingPhysics/Schroedinger. One dimensional potentials, non-interacting particles. The code is clean, graphics based on github.com/processing/p5.js, and all maths from scratch. Source organization and comments are typical of numerical code, the anonymous author is was likely a Fortran user in the past.
A potential change patch in sketch.js:
-   potential:     x => 2E+4*Math.pow((4*x - 1)*(4*x - 3),2),
+ potential:     x => 4*Math.pow(x - 0.5, 2),

Quantum Mechanics 5b - Schrödinger Equation II by ViaScience (2013)
Source. 2D non-interacting particle in a box, description says using Scilab and points to source. Has a double slit simulation.

Visualization of Quantum Physics (Quantum Mechanics) by udiprod (2017)
Source. Closed source, but a fantastic visualization and explanation of a 1D free wave packet, including how measurement snaps position to the measured range, position and momentum space and the uncertainty principle.

I Was a Starter Wife by Justine Musk Created 2025-04-16 Updated 2025-07-16
Very good article. She actually writes very well, and is very funny and insightful in many points. The little details are very interesting.

It surely would be intolerable not to know Created 2025-04-16 Updated 2025-07-16
A beautiful quote fom Edward Titchmarsh:[ref]
It can be of no practical use to know that pi is irrational, but if we can know, it surely would be intolerable not to know.
Ciro Santilli believes that it is perhaps for this reason that simple to state but hard to prove theorems are so attractive.
I have come to realize that a few of the websites do seem to use virtual hosting, i.e. multiple domains per IP, and I put a bit more manual effort into looking at known possible IPs that had a relatively small number of domains in them.
This led either to finding a few new domains, or placing existing domains in the same IP as another domains.
From now on I'll consider any IP with more than two hits to be an "IP range".
Furthermore, I now found new hits on nearby IPs of 209.162.192.49 rastadirect.net which was given by Reuters, thus establishing a new IP range there. Apparently I had simply failed to check IPs around one of the possible reverse IPs for it. The new finds are:

Sources and methods Created 2025-04-15 Updated 2025-07-16
"Sources and methods" seems to be an official CIA/NSA terminology to talk about the main categories things that whistleblowers were not supposed to whistleblow.
The term is more broadly used however outside of the NSA, e.g. it is also present on this website which talks about the CIA 2010 covert communication websites fiasco.

This seems to be a bit like CC BY-NC-SA but with the NC slightly relaxed in which you can use for commercial, just you have to give back.

This is a cool project that attempts to make it easy to emulate any of the three operating systems on QEMU.
Unofrtunately as of 2025 the project was falling a bit back on support, and the latest versions of the two closed source systems were buggy, tested as of quickemu 4.9.7 on Ubuntu 25.04:
