If it started: 0.999… = 1 - lim(1/n) then maybe we can talk, but I have no idea where 0.999… = 1 - lim(1 - 1/n) comes from, that’s just incorrect

I don’t have a whole lot of experience with different racks, but I did pull the plug on a 12U one recently. It surprised me how much it helped with organization and cable management. I knew it would make those easier, but it instantly solved all of my previous organizational woes.

Definitely recommend!

This is cool and all, but Wi-Fi and Li-Fi are equally “light-based”, it’s just using different frequencies. A higher frequency means potentially faster data transmission, but at the cost of faster attenuation. We see this with 2.4GHz vs 5GHz wifi already, and this sounds to me like a more extreme version of that
