Turn off screen via ssh

Hi, new to Ubuntu and set up a home lab with a laptop. I had a difficult time finding the command to do this, especially over SSH because some commands require being at the terminal to do this and I am running headless with no gui so I cannot just open a menu.

Anyways, here is the command:
echo 0 | sudo tee /sys/class/backlight/*/brightness

Cheers!

Hi, I am a college student with some extra free time. I got through school with Khan Academy and other educational Youtube channels. I found their videos to be very easy to follow and understand but I always felt like I had to test myself for understanding later to make sure I really got it. I know Khan Academy has short quizzes after each lesson but I really like Kahoot since I can play it with friends in a study group or practice them on my own in flash card mode. I started making quizzes on my own but found out I can get verified and share them online for anyone to use. All the other creators on the platform cater to younger audiences or trivia. I have a few quizzes on there that I made for my college courses and a few I made for my younger siblings in high school dealing with book reports and AP exams.

I haven't found anything online similar to this (that isn't paid, I don't charge for my quizzes) and wanted to get some feedback on any subjects you think I should cover or if anyone finds this useful.

Cheers!

I see a lot of posts about study music. Some people like it and some don't--I personally don't. But I still need something to drown out background noise. White noise is terrible and nature sounds are okay but they weren't doing it for me.

I looked up some articles as found out about binaural waveforms. TL;DR two different sounds played from two sides of a speaker or dual channel headphones that interfere in your head. It is supposed to be good for concentration, and it works for me.

Many people have mentioned this in passing on some posts but never linked how they play them. So I made a browser-based generator you can try out.

I did some research and documented how I made it, and if you are interested, you can read the docs.

Cheers!

I don't usually listen to music while studying, but read about cognitive research on the effects low frequencies while concentrating.

So I built this tool that does just that:

https://plateau-player.vercel.app/

Tune your own combination with a specialized synth and overlay your own music on top in the site or in another tab.

I open sourced it so it is completely free and more information on the research is on my github:

Let me know any comments/suggestions.
