If you unlock your phone, then you can sell it to anybody on eBay once your contract is up/you are tired of it. If you can't unlock your phone, then you can can only sell it to other $your_carrier customers, so $your_carrier gets/keeps another subscriber.
There are plenty of interesting moons, planetoids and asteroids upon which we could land and explore. Limiting the discussion to only "official" planets is too limiting.
Don't get me started on carbon films and metallized thin films.
Well, a soap film could wash off the carbon film at least. I've had to do that after working on my car. As for the thin metallic film, you might need something better than soap.
As a Rush fan, and having studied their lyrics and read Neil's writing, I have gained some insights into the philosophies they hold. I can only agree with you and not with the people you reference in your last sentence.
Not everyone who enjoys Rush music necessarily understands the messages and concepts in the lyrics.
This idea that the GPS industry "cheaped out on the filters" just won't die, apparently. The fact is, every engineering project is an exercise in trade-offs. Designs must balance the requirements with the budget and laws of physics. When you know the environment, you design towards it. In other words, the GPS makers designed their equipment based on the fact that the nearby spectrum would be low-powered satellite communications. Thus the filters on the front ends of the GPS receivers were built to reject that type of sideband interference. To do otherwise would not not be the correct design decision.
If everyone had to design their RF sections as you imply, every radio receiver in the world would need a 500 dB/decade "brick wall" filter to reject possibly ANY signal not included in its passband. These filters would be so large and complex as to render mobile devices impractical. The costs involved would make such devices too expensive to sell.
Please do not continue to drink the Lightsquared kool-aid. It is toxic.
Aside from a few million pounds (?) of it we have shot into space, all the metal that was here is still here. At some point, when the naturally available materials are simply too costly to mine, someone will figure out a good way to mine the landfills and dig those "gone" materials back up.
That's an overhand knot, not a square knot. If you want to join two like-sized ropes use the square knot; neither the overhand nor the figure-8 can do that.
You're right that the figure-8 is better than the overhand in most ways.
A square knot is properly used only as a binding knot. It can collapse and fail when placed under strain. If you want to joint two ropes (or glorious miracle graphene cables) use one of the interlocked overhand bends, such as the Carrick bend, the Zeppelin bend, or the Ashley bend.
I was in Houston a few years ago, and had to drive up north of town to get some equipment. Looked over and next to the highway, I saw DMC's place. Freaked me out a little, 'till I did some research later and found out about the resurrected brand and their manufacturing of cars from NOS and other parts.

GPS drifts, and has to be calibrated several times a day. DGPS and WAAS make it more accurate from 100m to a few cm though.
True, Real Time Kinematic DGPS methods with a broadcast or cellular correction signal typically get you below 3 cm absolute horizontal.
On the other hand, fast static observations and post-processing typically yields sub centimeter (usually less than half a cm) results for absolute horizontal positions, even with broadcast ephemeris. You can usually tighten up positions if you wait for precise ephemeris calculations to be published for your time window.
As for any drift, it is taken care of automatically. The ground stations continuously sync the clocks on the space vehicles.
It's absolutely disgusting how expensive these things are. I think it may be worth it to note that the site in question is in the business of selling their own hearing aids, though...
Exactly why I tagged this "Spam"
A maker of low-cost hearing aids posts a story about how expensive others are. News?
They are more like helicopters than planes. I imagine anything like that would use far more energy than this bird, not to mention making a lot more noise.
I've been disappointed in all the "Dune" movies that they haven't managed to properly portray the Ornithopters (as in the books).
Of course, I also hate that the MI in "Starship Troopers" didn't get the powered armor!
To get back on topic, this robo-bird is pretty amazing. There have been a bunch of mini-drones that can be used to spy on an enemy, but they all *look* like drones. These would not raise an eyebrow...
...that HL3 is actually possible!

Mr. Stallman, I thought you had an account here...

Unlikely. This thing was huge, like the size of an xbox (in a box) large and stuffed directly up the front of his shirt.
Maybe he had the all-you-can-eat taco bar for lunch, and just had not had a chance to empty it...

I just wish they had named it something pronounceable. "Chi b to the asterix" just doesn't flow off the tongue too well.. :)
That is all.
Beat me to it.
I miss Taco...

So it's the Ourobios?

We couldn't get the country to adopt metric measurements fer chrissakes. No way we could convince bubba that 2 AM is lunch break.
That's some funny shit right there! :)
Thanks for dredging that up...
They had to have a project to use the money they saved from the (now illegal) time machine program..
...Who gets out of the rabbit?
I was thinking more of something like the Honeywell Micro Aerial Vehicle:

true, but that complicates the expression "gas, grass, or ass... no one rides for free".
My first thought as well. Still, "Grassoline" is a pretty funny word...
