You're conflating insider trading and blatant corruption.

Imagine if a CEO of a company does something that would damage the price of the stock of it's own company, having shorted the stock before? That's not insider trading, that's (probably, I don't know the exact term) fraud and will lead to prison sentence.

Prediction markets enable the policymakers to make these bets. Arguably, there should probably be sorts of limit on who is allowed to be there. But there are still counter examples like Nancy Pelosi who somehow manages to go around these limitations in stock market.

That's whats currently happening.

There no reason to believe dark matter had anything to do with the Great Attractor, it's just that we can't see it due to it being on the other side of the galaxy what makes it great

The have to share their wealth because they are allowed to operate within a stable legal framework that everybody else is paying for except them. It seems like US isn't using their own taxes efficiently enough given that CEOs dont get killed on the street in the EU but they do get killed in the US. And these corporations arent willing to pay for that, well then they should not be allowed to operate here either.

i have a python library that does it: https://github.com/andreycizov/python-race

It uses generators and their yield as the yield point (and supports running arbitrary functions under a debugger)

Surprised you are getting downvoted - that's exactly how you get quick legal response, by taking actions that destabilise society. It doesn't matter who is right necessarily.

Yard Sale Pizza in London does it's own delivery and it's great where it's available. I hated that I had to use their website but delivery is always good and still warm.

You are also talking about a track with infinite mass because otherwise the reason train can change direction is because it's pushing the track northwards

heavenlyblue — Sun, 28 Sep 2025 15:42:25 +0000

I mean the issue is that British people are so uptight about the government id card when a) oyster/credit card allows somebody to track all of their movement b) there's plenty of information collection that combined can be used against you c) driving license is de facto gov id at the moment. The ship had sailed, you are fighting against the wrong thing and that's why this battle will be lost.

If you assume the availability of hosts is local to the perimeter of the infected hosts, then the relative growth is limited to 2/R where R is the distance from patient 0 in 2 dimensions. It's becuase an area of the circle defines how many hosts are already ill but the interaction can only happen on the perimeter of the circle.

The disease is obviously also limited by the total amount of hosts, but I assume there's also the "bottom" limit - i.e. the resource consumption of already-infected hosts.

If they use encrypted chat, that means they also somehow communicate between teams residing in different buildings, and I doubt they use wires for that. Does that mean it's radio? And if it is, what stops drones from homing in on their radios?
