  • That’s how fiber optic cables work now.

    You can use a laser for line of sight through the air, so you don’t have to lay fiber. So ship to shore

    How it is transmitted, others in this thread have said, light on is a 1 off is a zero, now just transmitting information in binary. You can go as fast as you can reliably turn it off and on, and understand the info at the other end.

    The real trick is using multiple wavelengths at the same time. So your data goes at 100nm mine at 110nm and yes that is a gross oversimplification.

  • 2 ways

    1 password manager

    1. I use them very often. I have a bunch of different yes complex passwords that I’m using repeatedly throughout the day so brute force rote memory….

    But yeah. Password manager

  • There have been some good responses…

    I’ll add my poor one.

    Adventurous people, wanting to be away from others would also weigh in.

    As above no one moved to Norway from the Fertile Crescent.

    People had to figure out clothing and fishing and hunting and farming then how all those things we different as they move further north. James Burke, in Connections points out how the plow changed. In light sandy soils a stick works, but in heavy wet clay you need heavy curved iron plows.

    So. Why? Because Bob smells, and never cleans up. We’re outta here — but over 10000 years give or take.

  • We use it at work, or rather I use it to text people at work I like.

    Working with info sec people helps. But I explained it and had them read about it and we all got on board.

    All you really can do is explain that text (sms) isn’t secure and that Signal is. And let people know you want to use it. But yes I wouldn’t try and force it that generally just annoys people.
