People post on facebook assuming the privacy model of facebook, where they have revokable control of who sees what they share. What do you think your friends would say if you told them you're keeping a personal copy of their photos even if they try to delete them?

Please stop this. This is a huge violation of your friend's privacy. Just because a friend has shared something with you on facebook doesn't mean they expect it to be in someone's personal cambridge analytica forever.

That's similar performance to NASA's Gipsy solver and a couple other PPP solutions.

The practical problem is PPP falls apart when there's any sort of multipath or noise, with will be the case for any receiver not in a completely open field. A single nearby tree is often the difference between 4cm accuracy and a meter.

No taxes on fuel isn’t a subsidy, there’s a natural race to the bottom on fuel prices because airlines can easily put more fuel in in a cheaper country.

Meanwhile, in Germany and France nearly 30% of the total cost of rail service is directly covered by the government, and it’s still more expensive than flying.

It does just stay there in a well run landfill, and microplastics mostly either come from tyres and cosmetics, or plastics that aren't disposed of in landfills.

There's some poorly run landfills, but how about we campaign to somewhat improve landfills instead of trying to reform all of modern society?

I am sure that the deletion of media files in services like Facebook has never meant to be absolute. Many of my colleagues believe the same thing that I believe: Facebook and other services do not actually delete data, they just mark it as "deleted" and purge it only if they need the space.

This is a dumb conspiracy theory. Facebook has made plenty of public statements that say otherwise, and there's a whole team that works on the system that ensures every trace is erased from disks, logs, cold storage and backups when deleting content.

Intelligence doesn't work like that. Take AIXI, define a reward in terms of paperclips and (if it were actually computable) you will kill everything.

Intelligence and any consideration of its goals at all can be completely unrelated.
