Quantum physics has proven (over a century) that photons can be entangled, meaning that two completely different photons, in different places, can instantly influence each other. Instant is a whole lot faster than electrons can move.

Also, re encryption. When photons are entangled, it can also be looked at as the same photon at two different places at one time, so there is no transfer of information at all because the data is being transmitted to and from the same photon.

Apparently 95 ghz is the frequency they use to burn the skin in heat rays, it's energy is fully absorbed by the first 1/64" of skin. From Wikipedia "employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 ÂF (54 ÂC) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting damage."
So yeah, penetration would be poor at best, unless between towers, or from LEO/MEO SpaceX built satellites to rooftop antennas.

How about Powershell? It has an ISE you can pickup and learn in less than 20 minutes. It takes about 2 hours just to get to the point where you're writing actual code. Powershell gives you full access to the .net library and runtime but the requirements to produce executable code are on par with Python. In fact Powershell looks a lot like "Python#" and IDLE.

You can get an ASUS X205 with Windows 8.1 preinstalled for about $200 shipped if you shop around, $179 if you're willing to walk in to a Microsoft Store.
That said it's not three times smaller, it's three times less volume. It's only 2cm on a side smaller, not much bigger than a Raspberry Pi B+, which let's be honest, isn't game-changing at this point. 2012 was a long time ago.

Although the moon is smaller than the earth, it is farther away.
