How to disable auto updates on Windows 10 Home
I've tried all kinds of things to stop auto updates on Windows 10 Home: Use psexec and disable the items in Task Scheduler, disable the services, run the service as a non-privileged user, edit various registry settings that are intended to influence auto update, try to be creative with "active hours" and play with the clock settings. Nothing that I found on the internet as of Nov 2022 has worked to actually stop the updates. I've found that editing the registry values shown below will definitely stop the updates. As of Nov 2022, this really works. Simply append ".bak" to...

How to make precise sheet metal parts (photochemical machining)

How to make etched metal parts.-All of the highest quality parts that I made went to the customer, but edge quality and photoresist adhesion is still a problem.
-The photomask dark areas can be expanded, and then the part etched for a longer amount of time to make the edges more perpendicular to the surface. I forgot to mention this clever way to improve the etch aspect ratio called "etch factor" http://www.chemcut.net/wp-content/uploads/2015/03/Chemcut_Thoughts_on_Undercut.pdf

High-speed X-ray video captured with a Dectris photon-counting detector. I show how the process works and how this detector is different than normal camera detectors.

The sequence of tiff files directly from the sensor contain a lot of temporal flicker -- probably because the X-ray tube itself has time-varying output. This isn't so bad at 60Hz, but quite a problem at 300Hz. I used Resolve's "color stabilizer" to maintain constant levels throughout a clip,...

Аттракцион и младенцы
Нью-Йорк, начало ХХ века. На фото – камера с недоношенными детьми в парке развлечений. За этим фото кроется долгая и поразительная история тысяч судеб, достойная экранизации, а ее главный герой, Мартин Куни (Martin Couney), годами жил под давлением критики и даже презрения.
...Drawing on a plasma display with a laser pointer
https://invidious.privacyredirect.com/watch?v=Oj4tRnLKN6U
An orange plasma display will retain an image caused by incident near-UV light. This is an interesting visual combination of photoelectric, hot carrier injection, plasma, and charge trapping effects.
Correction: The orange display is running at 700Hz, 130V in the video.
I realize that I may have conflated the issues of one-resistor-per-pixel and the display's ability to maintain an image throughout row scanning. They are separate problems that are both addressed by designing the panel to work on AC. Each pixel can maintain its state (on or off) by being supplied constantly with a lower "sustaining" voltage, and can be set...

Виртуальный мир имитаций
В Science пишут, что по набору ходов из шахматных партий обученный ИИ может указать, кто их делал. То есть деанонимизировать игрока. Каждый шахматист, даже любитель, имеет свой уникальный почерк игры, и нейросеть способна его выявить. В более общем виде, личность идентифицируется по присущему ей стилю принятия решений.
Следствия тут ожидаются глубокие. Если, чтобы запутать следы, можно еще исказить почерк или голос, то изменить стиль принятия решений это все равно что изменить свою психику. Так что, если вы проявляете себя в мире как мыслящий субъект, машина поймает тончайшие паттерны вашего мышления и по ним вас вычислит.
