This would work exactly like machine vision (because light is radio) but with much larger antennas, and a lot more transparent/translucent (and very refractive!) materials to cause more computational difficulties.

Why not just place static readers on all the doors - you'll immediately know when something moves from one room to another? Granted you won't know which way it was moving, unless it traversed another door. But, if you know the starting location, there you go.

Still might not work, without the door being closed you might not get standing waves.

I don't think he was referring to arcing.

Pop quiz: What happens when you boil water inside an sealed container?

HTC isn't a generic Chinese OEM. They have their own line of phones, and some of them are quite popular.

Lenses are wonderful things. You can have a display inches from your eye, with a focal point hundreds of meters away.

I'm sure he was thinking of a stationary or synchronous orbit anyway, which is a bit more specific than areocentric :P

I'd prefer people - trained or not - refrain from firing high-power rifles at airborne targets.

Maybe, but that's not the only place.

There's no reason the drone needs to transmit anything while it's tasked. Programmed waypoints and actions, and it uses GPS to navigate. Switch on control comms for takeoff/landing.

You really are an asshole, aren't you? The attitude isn't necessary.

You should get an ICMPv4 response with a type value of 3, and code value of 3.

RST happens when something borks up in an existing session, not in response to a SYN. (exception: when firewalls/NAT gateways are configured to reply with an RST, instead of dropping or ICMP).

Don't you kids know anything?

Wrong, you should get an ICMP response immediately.

Unless you're firewalling 127.0.0.0/8 to yourself, which would be incredibly stupid.

We won't really know this is true until it happens. I have high hopes for SpaceX - specifically I hope they can do much more with less. Either way though, this is a big win for everyone!

Unfortunately that cash can't magically feed and hydrate all the starving children in Africa or wherever your tears fall for.

If it could, you'd have a point. Unfortunately (for your point) it can't.
