Actually, compiling for pentium 4 or better already gets you most of these. Which is hardware that everyone has these days. But 64bit (system/OS) has only about a 70% market right now (for my application that is, which is a general desktop application)

dropped at a chopshop? where?
Imagine the look on the guys face. Walk up to a shady car dealers shop. Ask of they can handle an "needs to go missing" vehicle. And then you turn up in your Boeing 777. No problem right?
1) Let a 777 go missing
2) Drive it to a chopshop
qbittorrent is a great switch from utorrent. As it looks almost the same, without the crap. I switched my girlfriend torrent tool to qbittorent, and she didn't notice any real difference except for the lack of ads.
Because those are utterly crap. They provide a long arm and that's what causing the connector to break off quite easy at the PCB side.
Try blind mating an DVI connector. You'll find that USB is a charm compared to that.
I mean, it works in the same way, as in, it does not really work for anything but a tech demo.
This is pretty much how the leap-motion works. Nothing really new to see here, move along.
Whether you are measuring my height, fingerprint, penis size or whatever metric you come up with
Penis size is pretty useless as a biometric. It changes depending on the site being accessed.
So, that's perfect, password per site, and hard to fake.
I'm not, the code I maintain is to complex for that, and there are no real hotspots. 15% less runtime means a lot to me.
Go play KerbalSpaceProgram.
It's much easier to land on a moon then to get to an asteroid. Moons are quite large, have their own (significant amount) of gravity. Asteroids are small, have eccentric orbits.
We kinda do know how many planes there are flying.
Right now there are 10365 planes flying over the world. They also perfectly tracked the last few plane crashes up to the moment they disappeared. So position is covered.
Print heads can be tiny:
The problem is not slinging the head around. You could even do that with much more speed then is done right now.
However, the real problem is cooling and bonding. If you print quicker you need to cool the material quicker. If you cool it quicker, it doesn't bond to the rest of the material really well.
We generally speak in mm^3 / second when we talk about printing speed these days. As that's what counts in the end. Volume per time. With the accuracy we want, naturally.

Did some programming&debugging from inside a 3D printer:
Pretty much all lies from the start.
First off, almost nobody is missing steps in their cheap 3D printers. They simply do not move fast enough for that to happen. And if they are missing steps you have a bigger issue, usually lots of friction somewhere.
Secondly, 200 steps per rotation is normal for motors. However, the drivers everyone is using do 16x microstepping, good for 3200 steps per revolution. Accurate steps per revolution. That's better then 4096 +- 2 steps.
You also lose the close coupling between the 4 axis that you need (the feed stock of the material is also an axis that you need to control), which is a big deal in running accurate prints.
The cheap hobby servos will also have mechanical play, which will cause vibrations to be transferred to the head, which will result in a reduction of print quality.
I'm also willing to argue that it's more expensive. But I didn't do the math on that part yet.
(Who am I to say so? Just a guy who has been working at Ultimaker for 2 years. Kinda know what's needed for quality 3D printing at a low price and what's not)
I worked in this area 5 year ago. The switches have been replaced by a 2nd CPU which handles safety, and cannot be overridden from the main CPU.
So, all-green cannot happen. But the systems are far from safe. System I worked on was based on Linux, had pretty much an open-telnet server running. But is intended to run on a private network, not connected to the internet. However, connecting to this network you could own all the lights in seconds.
But, as you say, the value of this would be low. You could disrupt traffic flow for a while. But that's it.
