Woah there horsey, you're basically sticking anyone that thinks reactionless drive might be possible into the crazy conspiracy theory category, and there are plenty of people that are interested in honest reproducible research on the topic.

Just blanket suggesting that it is in no way possible without any evidence is no better than blanket suggesting it is possible without any evidence (well, it's a little better, since the laws of physics are on your side, but...)

Who said the text persists, you could take it off the phone and type it in to compare against any existing salted hash. Still not good security, but not necessarily stored in plaintext.

Why wouldn't you use redundant switches rather than n(2) servers?

Once you're planning work arounds for the "assume half your servers fail" scenario, I think it's time to admit that eventually, something is going to go down that is not automatically recoverable.

I'm not him, but it looks like their curriculum is licensed in the github repo under "Creative Commons Attribution-ShareAlike 4.0 International Public License", which according to this:

Would suggest that anyone could take their curriculum and rehost it with attribution if they were to "go private".

> Uber and Lyft simply don't want to do this because it threatens their profit margins.

You do understand how silly that sounds right? They want to protect their profit margins because... they're businesses! Uber and Lyft both said beforehand that they'd leave if they were forced abide by the silly measures put in place by the Austin silly council, so no, it does not make sense to blame them.

The Austin City council members that promoted the ban had received campaign contributions from the Texas Taxi Lobby. It was never about having verified names, it was about making money for Taxis.

That's already a thing, Google GPS based NTP servers with a TCXO or Rubidium reference. You can buy one for ~2000$ that will use GPS, or Cellular as a time reference, and can add options like a Temperature controlled crystal oscillator (TCXO), or a Rubidium reference (basically, small atomic reference).
