  • Fiber can deliver a single 800gigabit connection over a single strand of fiber, and if you have multiple connections you want to run over a single fiber you can use different colors for each connection and run theoretically up to 2048 different connections over a single strand of fiber. (Currently most commercial deployments top out at about 160 connections per fiber strand)

    Since these various connections are all made up of specific wavelengths of light, they can be “switched” by simply running the light through a prism, meaning a ton of your network infrastructure is entirely passive and doesn’t require any electricity to operate, reducing downtime, complexity and cost

    One downside of fiber is you generally need one connection for uplink and one for downlink, but there are bidi transceivers which either use 2 wavelengths, one for uplink and one for down, or will time share uplink and downlink. Or since each of these individual strands of fiber are incredibly small, literally about 7 microns across, you can pack hundred or even thousands of strands of fiber into one cable.

    Fiber also operates at literally the speed of light, meaning the connection to the Internet is incredibly low latency. Fiber also doesn’t rust like coax or telephone wires. As long as the actual fiber isn’t broken you can keep replacing the transceivers at each end indefinitely to upgrade the connection

    I will agree though, it is super cool that multi-gig connections ultimately are possible over existing coax networks. I didn’t think I’d see it but here we are!

    Edit: I was a little out of date. Currently up to 1.6Terrabit over fiber












  • Make it 60-72 hours and your death will still be fresh enough for it to be relevant, but plenty of time to figure out how to work around whatever calamity might prevent still-alive you from stopping it. It’s even enough time that if your death makes the news it’ll have been seen by most relevant journalists and newsrooms already so they’ll have more context for the strange email they find


  • When my daughter was about 1.5 she would wave like that, waving so she could see her hand correctly.

    Not long after that she’d dismiss people she didn’t want to deal with with a little blown kiss and a wave. So at the doctor’s office they had two nurses come in to give her some shots and she kept doing the little kiss and wave and they went “aww she’s blowing kisses” and my wife said “no she’s actually trying to dismiss you”


  • My grandmother was born in 1940 and told me when I was little about when her family first was going to get a TV she thought it would be like a radio with a little screen on top that you’d wander over to and peek into for a visual when you needed one for the radio drama you were listening to. As I got older I second guessed my memory of her telling me that (because she’s old but she can’t be that old!) and then she told me the story as an adult again and it all makes so much more sense now



  • When I was a kid my dad would often pull up the NORAD Santa tracker on Christmas Eve, and that combined with seeing the film War Games at way too young of an age had me believing in Santa for much longer than I should have because “why else would the federal government devote so much money to tracking him?” I think it was specifically seeing the exact same animation of him being welcomed into a country by a pair of fighter jets for the third year in a row that finally killed that line of reasoning (because obviously the NORAD Santa tracker site is shot with television cameras or something)

    Kid logic is wild
