Trenching is really the only sane way to go. If you're dealing with farmers directly and forming a cooperative, you don't have to ask any utilities for permissions. You simply trench on people's land and that's it. You still need to deal with the county for right of way to snake under roads, but that's a minor inconvenience compared to dealing with the pole-owning utilities.
Umm what? To start with they can have an old beige box as the router, and secondhand media converters are cheap as well. They don't necessarily need gigabit haul, probably 100mbit stuff that's dirt cheap will do the trick. And nobody lays down a single-strand fiber cable!
Especially that in the rural areas you can really trench very quickly as there's almost no other infrastructure to deal with -- just soil and an occasional road, usually unpaved.
Are you serious? Rural America votes, and their votes affect you. Do you really want them not to have at least potential access to the wealth of knowledge and "dissent" that Internet offers? Consider the alternatives: they'll only listen to the local ClearChannel station and watch Fox News OTA. I'm not saying an average Joe Redneck is reading random wikipedia article each day to edify himself, but your way of thinking makes it not merely improbable: it becomes impossible.
If you go to such a talk while knowing you have PTSD due to a talk-related experience, it's you who is stupid for bitching about it. Nobody forces you to go to such a talk. The Ada Initiative is here acting just like a bunch of whiners who think that their cause justifies the whining. Sorry, AI, you're not intelligent.
The anti-segregation activists were breaking the law too. The fact that there is a law doesn't necessarily make it good, you know? How else can one fight immoral laws?
Last mile is important, but quite often the long haul is also done with hidden and perhaps forgotten but still significant public subsidies. In many places the long haul fiber is carried by the power utility companies, tucked inside of their high voltage lines.
Those people we were fighting against were used to poor conditions, were quite resourceful compared to a typical "useless out there" U.S.-ian, and were physically way more fit, on average, then I'd image NRA members to be.
Look, you fuckers, you can't use copyright law "out of respect for the injured", mmkay? What kind of an idiot would come out with this line for an excuse? You did not send an "I wish it were so" takedown. You sent a takedown under DMCA, and you've just publicly claimed that you've perjured yourself! Just one more reason for me to otherwise ignore NASCAR.
If you're doing hiring, it is your job to read those resumes. That's what people don't get. If your attitude is "hiring you is just extra work", you should have a long look in the mirror. Maybe you shouldn't be doing hiring, then.
You need the time to go through them. That's all. Tell your superiors they can't expect you to do a good job without, well, allocating the time for it.
Having kids is no excuse for lack of rationality. Soccer moms demonstrate otherwise, and think they are on a high moral ground while doing it. It's quite disgusting. Yes, I have kids.
The quadcopters are very basic, sensor-wise. They may have an inertial measurement unit onboard, or may not, I don't know. They probably know their battery state, and maybe motor current. A reverse channel from a quadcopter adds extra weight, I'd avoid it if I could. Other than that, everything is sensed by a standard motion capture (mocap) system that illuminates the scene with infrared light and tracks the reflective marker balls on the quadcopters and the pendulum.
They put small balloons filled with flour as dampers at the end of the pendulum. This is simply to provide something that will dissipate remaining kinetic energy when the stick hits the quadcopter -- there's always some velocity mismatch. If it was a bare stick, there wouldn't be enough friction to keep it on the quadcopter, and it would bounce away right after touching the quadcopter during a capture. Remember that our finger skin is pretty special when a bit moist -- it grips random things extremely well. When you have a carbon fiber stick and a plastic platform, it's a different story.
Agreed. My bet is that the motion capture is probably using recent Vicon cameras that do 2D tracking in hardware (on an FPGA or an ASIC, your pick). It's power hungry. Never mind the 3D tracking, in this case it'd be done by the tracker software running on the PC -- power hungry too. No point in putting nay of that on a quadcopter, imho.
The way they do it is state of the art at the moment. You pretty much don't want anything extraneous on the quadcopter. If their motion capture is 120Hz as you say, they'd be having an IMU on the quadcopter. If they can do 1000Hz, like they well should if they can afford it, they probably don't need an IMU -- just a completely receive-only quadcopter.
The quadcopters can't do any of that on their own at the moment because they'd need to know their position in space relative to each other and to the stick. You'd need lots of heavy image capture equipment on each quadcopter. This is a complicating issue that's entirely orthogonal to what they are doing. They are after control algorithms. Once you have that, you can play with moving sensors back to the flying platform. There's no point in putting the cart ahead of the horse, so to speak.

Comment of the day, right here!
Doesn't make them much more fit, from what I've seen so far.
Yeah, because DHS gives a fuck about mess in the airline property (airplanes), ha ha.

Useful Arts, that'll be with a triple helping of chuckle, and a schmilescinoscherry on top :)
IOW: Something being prohibited doesn't make the results owned by $BIGSPORTSHONCHOS$ :)
That maks MLB and NFL fuckers too. Thanks for clearing it up for me, not that I was ever in love with large scale U.S. sports anyway.

Holy overgeneralization batman!

Way to miss the point.
Those quadcopters are a bit faster than humans arms are, and things are moving towards getting everything even faster still.
Those quadcopters are dumb slave devices. They have no built-in intelligence of any sort.
The quadcopters are very basic, sensor-wise. They may have an inertial measurement unit onboard, or may not, I don't know. They probably know their battery state, and maybe motor current.
