Friendly reminder that Alzheimer's may entirely be driven by Candida yeast. If you know anyone diagnosed with Alzheimer's I strongly recommend doing an Organic Acids Test for d-arabinitol specifically to see if it's high. If it is, candida could be the cause (not of all Alzheimer's, but some cases where d-arabinitol is high).

Warning: This just fucked my 2k$ 4k LG display. I ran the website 15 minutes ago and quickly closed it after 15 seconds. My screen is still flickering in the portion of the screen where it used to be the webpage. I rebooted. Still happening FML please put a big disclaimer.

If it's anything like my something something UltraGear LG monitor, disconnecting power for two minutes or so might help.

I had severe ghosting in the shape of YouTube's home page and disconnecting it solved the issue.

Apparently the type of panel they use tends to do stuff like that.

Just a warning - running this for a few seconds has left my secondary display with an ongoing flicker which seems to be improving after 10 minutes and a reboot. [edit to add] 10 minutes later - the flicker has gone (or I can't perceive it)

found that something like this fixes it https://youtu.be/t6jlhqNxRYk?feature=shared&t=8468 play it in full screen for a few seconds

I'm not sure what just happened but this webpage literally damaged my monitor. There is now some flickering over the whole screen (it's not my mind, I filmed and checked my mind with another screen)

What is going on? Burn-in is understandable but “the content on my screen flickered” should not be a breaking edge case.

First: in mice, raised on a doxycycline-containing diet. Second: if I've understood correctly, there's no idea about what causes Alzheimer, which would reduce the significance of finding reduced levels of tau. Third: there was physical vibration at 40Hz. This cannot be reproduced with headphones or earplugs, let alone a computer speaker. The experiment used a 12 inch sub-woofer (at undocumented levels, but I assume t…

Tonality is a more ancient part of us than linguistics. As we get better and better sound simulations + measuring tools, I think this type of science is going to get a lot more interesting.

Given the problems people are having with their monitors, and the inherent issues with timing on a 60hz screen and timing on a enormous mass of abstraction... Using a microcontroller with a DAC and a LED array seems particularly well suited for this, while still being firmly a beginner level project.

As well, a cheap Dayton transducer may be a reliable entry point for producing the 40Hz
