after a nar nar day in pow pow cuttin freshies up to your nippy nips, you'll change that assessment!

(my email address was once inadvertently put on a mailing list for the planning of a bachelor party ski weekend, people I did not know or have any connection to, and that's the way they talked. i enjoyed it so much i didn't confess till they demanded to know why i hadn't RSVPed yet)

> He’s working with a company to develop nanosensors able to detect movement in the iceberg so he has advance warning of a flip

The "nanosensors" doesn't sound likely at all. If I were to tasked to create a "iceberg sudden flip detector" I would break the problem into two parts. Part 1 is monitoring the shape of the iceberg as it is changing. Part 2 is modelling how stable the iceberg is given the measured shape. Both sounds like a wicked hard problem even if you have a large team of engineers.

For the first maybe you could do periodic ultrasounds from the inside out. Embeding an array of accustic transducers and an array of microphones in the ice and then using signal processing black magic to pick out the shape of the echo you get back from the ice-ocean surface. Or just hang around with a ship mounted side scanning sonar and monitor the iceberg from the outside.

The second one should be a "simple" monte carlo simulation. But to validate it you would need data recorded from the evolution of many icebergs. Which I suspect would be expensive and lengthy to obtain.

"Nanosensors" is useless technobabble. But I bet you could do it by carefully monitoring the rocking of the iceberg in waves. Watch the period of the berg's movements; as the melting brings it closer to instability, the period would get longer and longer, which could give you some warning. (You couldn't predict the consequence of some portion breaking off, but it might give you something.)

Tumbling, just like a generic front-load washing machine.

Interesting to learn you can identify the real country/area of origin using probe latency. Though could this be simulated? Like what if the VPN IP just added 100ms-300ms of latency to all of its outgoing traffic? Ideally vary the latency based on the requesting IP's location. And also just ignore typical probe requests like ICMP (ping). And ideally all the IPs near the end of the traceroute would do all this too.

To use an example, 74.118.126.204 claims to be a Somalian IP address, but ipinfo.io identifies it as being from London based on latency. Compare `curl ipinfo.io/74.118.126.204/json` vs `curl ipwhois.app/json/74.118.126.204` to see. If that IP ignored pings and added latency to all outgoing packets, I wonder if that would stymie ipinfo's ability to identify its true origin.

Ideally, there'd be a way to subtract lag. (A non-causal network switch? Would be big business...)

Gorgeous, gorgeous, gorgeous. Spirited Away's image of a train moving through shallow water has always grabbed me.

Seems like there is no way to actually make those collide with each other. Even when they are really close, they are just make a pass go in other direction.
dtgriscom · 13 days ago
Just for fun, I set it up with six bodies, each 1 unit mass and at 1 unit from origin, but along the three different axes (an octahedron). No initial velocities. Start the sim, they fall towards the center, and then BLAMMO they rocket off in opposite directions at high velocity. Clearly, no conservation of energy here (at least when the bodies are arbitrarily close to each other).

Simple pleasures.

"100% finer", who uses language like this? I don't even know what it means. How about "half the diameter"?
