So history and political science are useless, and should stop being taught in schools?
Wikipedia is very slanted towards recent and Eurocentric events.
Yes, this is somewhat explainable in terms of how much literature has been produced over time, and how much literature is accessible online. Wikipedia isn't the problem here, the problem is that the authors didn't acknowledge this issue, let alone attempt to account for it in their computation. (though it's a long paper, so I might have missed where it was discussed)
whose idea was it to use metal detectors as gun detectors? Time & technology change... and detection methods must change with them.
If non-metallic guns were truly viable, they would have been used 20 years ago to sneak past metal detectors and kill judges and politicians and airplane pilots. Plastic manufacturing has been around for a long time, the only thing 3D printers do is reduce the cost. There are well-funded spy agencies and a few individuals who would have paid hundreds of thousands of dollars for a single gun. And yet none has materialized: [1] [2] [3]
I can only speak to how my local hackerspace handles it, I don't know how others do.
At this one, most power tools are owned by individual members. If someone gets hurt and wants to sue someone, the only person they can sue is the individual owner. On one hand, this sucks because it puts all the burden on individuals' shoulders. On the other hand, it decreases the chance that someone tries to pay legal fees from prospective damage awards, because damages are likely to be very small, so it reduces the chance someone will lawyer up.
Our hackerspace hasn't had any incidents yet, so I don't know how well this plays out in practice.
The goal is to "engineer software-based radios that transmit data faster than a competitor using identical hardware".
The goal isn't to develop fancy new hardware, or to use an overwhelming amount of power. The goal is to develop fancy new software.
With frequency-hopping and time-hopping techniques, if you can intelligently adapt to the local interference, and transmit in the time and frequency gaps where the interference doesn't occur, then you can transmit more data for the same amount of power. That's the goal.
But isn't it difficult to get a RAM dump, you say? Not really:
Interesting fact — There's an 85% fatality rate for the speed record for any boat. This sport is extremely dangerous.
The sailing speed record is 80% slower than the overall boat record, so the sailing record is a little safer. Nonetheless, one of the SailRocket crashes led to the pilot having a broken helmet.

The term "SCADA" is specifically used for industrial processes that have to be connected by long-distance networking.
The hardest part of climbing the ladder of success is getting through the crowd at the bottom.
