And yet their infrastructure is hosted on AWS

if we take it as true that light speed is the same in every direction

This is the crucial assumption, that to my knowledge hasn't been proven or disproven. Because the alternative, light goes faster in one particular direction, is also perfectly consistent with everything. And if you're moving atomic clocks, correcting for time dilations requires you to make assumptions about the one-way speed of light (which we only know from measuring roundtrip times)

That's just shifting the problem. There is no known way to reliably sync remote clocks except by sending packets and assuming the round-trip time is symmetrical. This is a known problem in physics: https://en.wikipedia.org/wiki/One-way_speed_of_light

That would be a great follow-up joke.

Now if she chooses the dirty pickup line, you respond with "girl, are you a viking steel crucible? 'Cause I'd put a bone in you."

What will the cops do, shoot them all?

His security detail might. Shooting civilians is their specialty.

You don't get to declare that your body shaming is "conventionally funny" and everyone else is wrong. That is incredibly self-righteous.

Why do you think people get so insecure about their bodies? It's precisely because of "jokes" like this that keep emphasizing certain body standards.

May you live in interesting times. What I wouldn't give for a calmly moving trolley.

So what is the reason for doing it that way?

It's the exact same argument as with cops, I don't see how you can come to a different conclusion. Individually they might be courteous, but they choose to be part of a fundamentally unethical system and their very existence is an injustice.

The phone number link means forward security isn't possible. If ever the encryption is hacked, all your messages could be forfeit by anyone who's simply kept the encrypted data.

Can you elaborate on that? Obviously the phone number has privacy implications, but I don't think it can be used to decrypt messages. In the signal protocol, encryption keys are exchanged using ECDH (so wiretapping doesn't work) and periodically rotated (so even knowing the encryption keys at a certain point doesn't let you decrypt messages after that).

Something my opponents always smugly point to right when I've found a mate in 15
