Zermelo-Fraenkel set theory Updated 2025-07-16

One of the first formal proof systems. This is actually understandable!

This is Ciro Santilli-2020 definition of the foundation of mathematics (and the only one he had any patience to study at all).

TODO what are its limitations? Why were other systems created?

Schrödinger equation for a one dimensional particle Updated 2025-07-16

We select for the general Equation "Schrodinger equation":

$x = x$ , the linear cartesian coordinate in the x direction
$\hat{H} = - \frac{ℏ ^{2}}{2 m} \frac{\partial ^{2}}{\partial x ^{2}} + V (x, t)$ , which analogous to the sum of kinetic and potential energy in classical mechanics

giving the full explicit partial differential equation:

i ℏ \frac{\partial ψ ( x , t )}{\partial t} = [- \frac{ℏ ^{2}}{2 m} \frac{\partial ^{2}}{\partial x ^{2}} + V (x, t)] ψ (x, t)

Schrödinger equation for a one dimensional particle

.

The corresponding time-independent Schrödinger equation for this equation is:

[- \frac{ℏ ^{2}}{2 m} \frac{\partial ^{2}}{\partial x ^{2}} + V (x)] ψ (x) = E ψ (x)

Bitcoin Forum Updated 2025-07-16

bitcointalk.org

Good article about its history: en.bitcoin.it/wiki/BitcoinTalk

Founded by Satoshi Nakamoto, making it the earliest and one of the most important Bitcoin communities. TODO official in any way? Who founded it?

Instance of Simple Machines Forum, an open source, PHP-based forum system.

Some notable appearances:

in 2010, it is where Laszlo's pizzas offer was announced
it was used e.g. on the Mt. Gox investigation: youtu.be/tJ-TsrK6SuY?t=2018
Jimmy Zhong's investigation: youtu.be/pxvd1YOMGxU?t=1004

How to hardcode subtitle into a video with FFmpeg? Updated 2025-07-16

On Ubuntu 20.10, just:

ffmpeg -i input.mp4 -vf "subtitles=subtitle.srt" output.mp4

To change font size: stackoverflow.com/questions/21363334/how-to-add-font-size-in-subtitles-in-ffmpeg-video-filter

ffmpeg -i input.mp4 -vf "subtitles=subtitle.srt:force_style='Fontsize=64'" output.mp4

The default appears to be 24, so just multiply that by whatever seems like a reasonable factor.

Note howver that .ass subtitle files can contain style information, which ffmpeg respects. Aegisub can produce and preview such styles, making .ass one of the best options.

He's good. Sometimes a bit repetitive, but generally pretty good.

Only the "original" videos matter. After those it became crap.

www.youtube.com/watch?v=h6DtVHqyYts Big Rigs: Over the Road Racing (PC) (2014) is perhaps his best video.
