Slightly related, is there any analytical writing on the human side of security? How to build organizations that are resistant to intrusion in various forms?

From reading books and watching movies as well as applying a bit of common sense, organizations like spy agencies or terrorist networks with more or less independently operating cells work with a strict least-privilege type model such that a mole in one part of the organization doesn't compromise the organization as a whole. And, I'd guess, at least in more formalized organizations, strict logging on who does what etc.

All this obviously adds a lot of overhead and friction in communications, which, say, a business operating in a competitive environment can ill afford. I'm quite sure there's no "magic pill", but rather a bunch of choices with tradeoffs (like security vs. ease of cross-team communication I touched on above).

In fish...

"Contrary to expectation, the synaptic strengths in the pallium remained about the same regardless of whether the fish learned anything. Instead, in the fish that learned, the synapses were pruned from some areas of the pallium — producing an effect “like cutting a bonsai tree,” Fraser said — and replanted in others."

This is a very counter intuitive. So there are existing neural connections (formed somehow previously...) and new memories form by pruning these connections? Crazy

The insurance industry does a pretty good job of “what is the probability that you will die in the next billable period” - but they would never reduce the bet to “what is the probability that you will die today?”

You say it’s “essentially impossible to model” something that hasn’t occurred before.

Nations have engaged in a lot of wars.

Nations have engaged in a lot of wars they could not possibly win.

People have committed suicide to harm other people. Many many times.

Nations have developed weapons and then used those weapons on other people.

Countries that have engaged in arms races and stock piled weapons have then gone to war. Many times.

In some decades we do more of these things and in others we do less.

To say it’s hard to model, or the models are imperfect (as all models are) - fine. To say it is impossible to model - that’s very naive.

So how does it work when there are multiple of these systems (CIPS). Is double spending possible?

We haven't blocked the domains, we are asking people to move. There are plenty of other choices out there when it comes to infrastructure services so this isn't "deplatforming". I sympathize with people that are not pro regime but ultimately even those tax dollars they may generate go to the regime. We have people on the ground in Ukraine being bombarded now non stop. I cannot with good conscience continue to support the Russian regime in any way, shape or form. People that are getting angry need to point that at the cause, their own government. If more grace time is necessary for some to move, we will provide it. Free speech is one thing but this decision is more about a government that is committing war crimes against innocent people that we want nothing to do with.
