One of the biggest reasons a lot of people that use Google+ is that it's easier to keep posts relatively private. I don't need to have pictures of my kids published to everyone on the net, or tell everyone in the world when I'm on vacation, or have all kinds of crap out there for potential employers to find. Google+ makes it easy to post to a small (or large) group without posting publicly. Basing numbers on public posts is FUD, it's worse than meaningless, it's misleading.

What they are, admittedly awkwardly, trying to say is that the Fast Radio Burst was detected as it was happening, enabling follow up investigations to catch the immediate after effects. Previous such bursts were detected much later, too late to do any kind of follow up leading some to question if the events were even extra planetary.

Now now, we all know vacuum stabilization events travel out from their sources at the speed of light, if it were to happen it would be against the laws of physics to see it coming.

More interesting is one of the actual proposed explanations. A massive spinning magnetron gradually slowing down until centrifugal force can't keep it from collapsing into a black hole anymore. And when the source of the magnetic field suddenly gets cut off from the outside universe by being engulfed by the event horizon, the magnetic field has no where to go but... out. The most powerful magnetic field in the universe getting converted almost instantly to energy; creating a spark that lasts seconds and outputs more energy than the sun has in the past million years.

Round trip to a satellite, 3ms. Hell, call it 15 if the angle is high. Then the satellite hops, which would take place at c with a microwave link, compared to .66c with fiber. Not to mention there are many fiber links that are anything but direct line. I could easily see such a system outperforming ground networks when it comes to latency. Now, congestion could be a problem obviously. It will have to be seen if they can put enough links into orbit cheaply enough to prevent issues.

I had a teacher fail me on a programming assignment because I was using things she hadn't taught yet.

Depending on what you mean that isn't necessarily a bad thing in a programming course. If the purpose of an assignment is to learn about data structures by recreating them and you back everything with std:vector, you aren't really completing the assignment even if all the functionality is there. Of course, it's also entirely possible that the teacher just didn't know what they were doing or, more concernedly, simply on a power trip; so no judgement, just pointing out a possible counter argument.
