Old 747s have terrible fuel economy which is their highest operating cost, plus they have to be completely torn down (seats out, overhead bins out) for a complete airframe inspection, engines rebuilt etc every 6 years or so and it costs millions of dollars to do this "frame off restoration" with qualified FAA certified mechanics. After the fourth or so complete restoration the cost-benefit ratio slips in favor of buying a whole new airplane. This isn't like buying a pickup truck for personal use which you can just drive until the wheels fall off, swap in a new rear axle and drive it another 500,000 miles without ever doing a proper inspection of the frame, wheel bearings, etc.
In addition to the major overhauls, they do slightly less major overhauls every 4 years, and they still do a full 2 day inspection every 18 months or so.
Eventually these old 747s get sold for a song because the maintenance to keep them flying isn't worth it. There's a 747 in the background at the Top Gear test track (which is a converted airfield) that is parked most of the time or used as a prop for movies but is still airworthy when someone needs an extra cargo jet, or needs to fly a football team to Australia or something for top dollar. But they're not economical for daily use by major commercial airliners anymore.

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.

Yeah retail salespersons are kind of dinosaurs at this point. You can't technically buy a car on Amazon but you can buy a road legal (in some states) scooter there. Inertia is the only reason you can't order a new Toyota Camry or Prius on Amazon and have it shipped to your house. You can do it with used cars on Ebay at least.
I'm not sure jobs or tax revenue are a good reason to impede forward progress though.

I'm not a vet student, but I did spend a night helping one study the sinuses of a large animal (they split in to large animal (farm) and small animal (pet) specialties) and some of the learning materials are a little difficult to wrap your brain around, in particular how the sinuses (voids in the skull) exist inside the skull, how they connect (or don't) and simply where they are. The brain has enough trouble understanding negative spaces, even more trouble trying to conceptualize the winding, twisting 3D negative spaces you can't ever directly view without cutting apart a skull to do so. Even then doing so only gives you half the picture, and in negative space.
There are some videos online showing the sinuses in "positive 3D space" but it's still only a reference (Everyone is different) so I would imagine having a 3D positive space model of a tumor you've never seen and can't see without cutting open someone's head would be incredibly helpful, especially since you can't just buy off the shelf reference material for human tumors like you can bovine sinuses.

Solar is already on par with electricity prices (which are mainly driven by the pool-table flat price of coal) and solar is expected to be half the price of electricity in 15 years. And that's in the first year. That means you get back 100% return on your investment in the first year. The next 25 years are just gravy (assuming no hail storms and your batteries never wear out). If you live in a hot state nearly free electricity during the hottest part of the day means you'll have a very predictable and very low electric cost for 10 months out of the year (12 if you have gas heat).
What I'm saying is, solar is already cost-effective, but in 10 years even with dirt-cheap oil, solar will still be cheaper, and there's no global fluctuation in locally produced and consumed solar energy.
Energy independence = less need for global intervention in war-torn oil producing states.

The hardware hasn't become less serviceable, it's that the hardware has shrunk to the size where it's not economical to break out the audio from the video, or the CPU from the audio and video, or the eithernet, disk controller, etc. As a result you end up with a tiny circuit board that costs pennies to produce, is easily maintainable and fits inside today's slim devices.

The last event I went to like this, 12 oz beers were $5 and cocktails were $6. Which for downtown Dallas is average, if not slightly below the median price. And it was pretty fantastic. As a vet, an engineer and a computer programmer we had a pretty fantastic time, A+ would go again. Let the schoolchildren enjoy the museum during the day.
