- Comment on If darker coloured materials get hotter in the sun faster, will a display with the screen on or off change how quickly it heats up? 1 day ago:
LCDs are designed to filter out extremely specific types of light, and in a specific direction.
It’s true that the changing optical properties of each crystal could affect the albedo, but whether white or black is more effective is beyond my knowledge. It might even be neither, but green instead.

No, and not because the effect is in any way small.
It is because a phone screen producing white light, looks white because it is actively generating white looking light. Compared to white paint, which looks white not because it generates its own light, but reflects other light, these are two different mechanisms for making things look ‘white’.
Your phone has a brightness setting, to keep ‘white’ the exact same shade of white despite whatever viewing condition you have. A white paint does not, and as a result, looks different depending on the amount of light in the room.
So in your hypothetical, a white phone screen won’t reflect less light as you presuppose - it’ll generate more heat internally - unless you cover the screen with white paint.

Before an instance does something malicious, how do you know it will be malicious?
Even if everyone there running it, & participating is pure of heart, how can you be assured that haXXors won’t simply break in to take advantage of that trust you’ve given them?
Banning bad instances is a reactive stance that only applies after damage has been done. Can you convince the corporate overlords to take that risk? And it only increases as the fediverse gets more popular, and more instances get trusted.

Yes and no.
Decentralized IDs exist, but will almost never be accepted by any large reputable institution.
Why trust every indie site to be 100% truthful, and definitely not full of malicious haXXors?
