I think it is LED technology. LEDs have a very small bandwidth. Even white leds are just three very small small bandwidth emissions.
The very tight intensity in such a small bandwidth is hard on the eyes. Even when compared with the same power of older lighting technology, which has a comparatively massive bandwidth.
LEDs could be designed to compensate for this better. They could add more different colours of LEDs to the matrix that makes up white LEDs.
Most common maybe. I feel most windows users aren’t actively choosing to use windows. It’s just what they are left with.
People usually choose to use Linux or Mac. As Linux is rarely preinstalled or like Mac more expensive (when it comes preinstalled) than the windows devices for sale. I’m not convinced given a fair shake, windows would have the market share it does.
Servers have highly informed people making decisions about their operating systems. When weighing the options about uptime, security, etc they rarely choose windows. Cost isn’t really a factor relative to the price and operation of the server.
Oat milk is just oats blended in water. The research is minimal. The marketing is where they put most of their money.
People have attached pens to 3d printers and used them to write letters, effectively print. Most consumer 3D printers are useing or based on open source software.
I think the issue is, printers are relatively cheap to buy and replace. So building your own and programming it hasn’t been necessary. Where as 3d printing was completely in accessible before the reprap movement. 3D printing software is open source as it is motivated by people wanting to build their own machines that could build machines. Something you couldn’t easily buy.
