Don't forget the minerals that will be left behind to clog the wall along with the mold. Locations that are dry enough for evaporative cooling to work are usually short of water, too, so this would be like a faucet continually running.
Only if you're looking up in the direction of the satellite, otherwise it's your head that would be about 1 pixel. Of course it's unlikely in either case that your your head/face would be contained in one pixel so it would more probably be split among 2 or 4 pixels.
GPS is just a stand-in for the system they would use on Mars, which would be a much simplified version using existing satellites and the transport vehicle for the lander itself.
The atmosphere in Mars is fine for a quadcopter if designed correctly. How do you think the parachutes on NASA landers work?
I'm not sure what you mean by "simpler" system, what would it be? AFAIK it takes signals from 4 GPS satellites to get a fix, I think that it could be done with 3 having knowledge of the approximate position. That's with 3 or 4 satellites with GPS electronics in view at once. This implies that there need to be several more than 3 satellites in the constellation to be certain of having 3 or 4 in the correct position at any time. I don't think that the orbits of multi purpose satellites would be the ones needed for GPS.
Parachutes are used to slow the descent rate of the landers and are then cut away as the descent rate is still pretty high. Other methods need to be used to bring the lander to touchdown. I guess some engineers experienced in origami might be able to design a multiple rotor copter that would be compact in transit yet unfold properly once the parachute slows the descent rate etc, etc, etc.
Well, the up front costs for the Martian GPS system will be high, that is to say, astronomical. May be some maintenance problems as well. Other than that and the near absence of an atmosphere it sounds good to go.
A couple of decades ago I was in a twin engine aircraft over the Amazon with some scientists who were collecting atmospheric data including distribution of smoke particle sizes, CO2, CO, humidity, temperature, Hg, etc. when it became apparent that some code I wrote wasn't working well with the interface on the aircraft (supposedly identical to the one in my lab). I was able to devise a fix on my (luggable) notebook, compile, link, and install it in flight and the rather bumpy mission continued. This was also been the only time in my life that a pilot has taxied an aircraft that I was on into the hanger at the end of the mission.
California has had a mask law on the books long before photo recognition, CCTV, etc. The purpose was to attempt to prevent masked people on the streets as this was (reasonably IMHO) seen as a probable precursor to some sort of in-your-face crime.
When I go out to the desert on a clear day I'm getting a lot of infrared, if it blocked out normal vision I wouldn't need sunglasses (except that the glasses block UV). Perhaps what was meant is that the lens that would be needed to focus the light would block the IR and the lens for IR would block visible light. That's generally true except for near IR (NIR) but to separate NIR from visible IR a filter to do that would be used just as it is used in digital cameras.
The article implies that it works across the IR spectrum but that's enormously wide - from about 700 nm to 1 mm wavelength with ever decreasing energy in the photons.
I think that there is less information in the press release than meets the eye.
That's already inexpensively available; it's called Automatic Flight Following (AFF). It's small, easily installed, and inexpensive to operate . Those that I am familiar with send a GPS position, including altitude, every 2 minutes via satellite to a ground station. I believe that track, not heading, and ground speed are calculated using the previous datum. The data are available for display on a digital aviation chart, map, Google Earth, etc. It's been available for many years. All of the US Federal fire fighting aircraft have them and that includes contractor's aircraft. I suspect that most US Federal aircraft have them no matter what their use.
The system that I've used will tag the last datum received if it has been more than 10 minutes since the last one and the icon on the display will be red. Probably the system could send alter text messages and emails, too. The display allows for viewing the last position of many aircraft or the track of a single one from an arbitrary time to the most recent datum.
This certainly helps discovery of a problem and provides a good starting point for SAR efforts.
I was really apprehensive when I discovered that Sync was powered by Microsoft after I purchased my Focus two years ago, and rightfully so. What did MS know about maps and routing? On reading the article's subject my first thought, too, was I wonder if there will be an update: probably not.
Here are a few examples.
Found that the voice commands lacked synonyms so one had to conform to Sync.
It would lock up quite often for no apparent reason and the only way to re-boot it is to go to the side of the road, park, turn the ignition key to off, and then open the door for a few seconds. One could then restart and it would re-boot.
On the occasions when I needed routing my wife and son would be reduced to hysterics as I tried to get it to give directions to the intersection of, say, Laguna Canyon Road and Pacific Coast Highway. It appeared that it didn't like street names of more than one word in this context.
Use voice commands to make a call (this and some other errors of the type were repeatable) "Call Jenny Rechel home". Response was "No home number for John Litton, cell or work?"
I took it to the dealer twice and got updates that have stopped the lockups and can now use it to call Jenny but some other, more fundamental, problems persist.
I must admit to being time traveler. I started time traveling in 1939, inadvertently to be sure. I had no expectations that my travels would be as interesting as they have been nor as boring, from time to time, either. I've found it to be so addicting that I'm plan to keep on, and on for as long as I'm able.
No matter what any government agency or official says about new limits regarding establishing back doors or weakened encryption in algorithms or hardware, interception of communications, analysis of meta data of US citizens communications, secretly installing root kits, etc. One must now, and forevermore, assume that they are lying. It will be outright lies (kind of hard now because they supposedly don't know all of what Snowden has passed on), partial lies, and misdirection.
The wildfire model appears to ignore some parameters encountered in wildfires: air temperature, insolation, wind speed and patterns in 3D, terrain, relative humidity, moisture in the plants, winds created by the fire, litter, and some interactions between the local winds and those created by the fire, to name a few. Perhaps there are analogs in the model.
It would have been more accurate to title this: "Do Earthquakes Spread as a Wildfire Model Predicts Wildfires Spread?"
Get a second phone line and change the plan for the first, if necessary to the least expensive available with voice mail. Let your contacts know about your number change. Unplug the first phone but check the voice mail when ever you feel like it. After you no longer get calls from your contacts on the first phone you might give up the line. Then the person who next gets that number will have a surprise. It may be worth the extra cost.
I've had my phone number for 5 years and am still getting dunning calls for the previous owner. A side benefit from using the "new" number is that I no longer receive annoying "spam" calls.
The link provided by the OP is 14 years old. This is not evidence that current GPS satellites have optical (or any of the sensors mentioned) on board. They could be on board but the optical sensor is designed to detect "the optical time signature of NUDET bursts " which is probably not the same as a wildfire shortly after ignition. If the detector could also designed or tweaked to detect very small fires this would be a real advance.
The detector is not just a camera with a telephoto lens and IR filter (works in Hollywood, though) , that would work for near IR (NIR) but not thermal IR (TIR) since silica glass is opaque to TIR and the silicon sensor array of the camera would not detect TIR. Lenses and filters must be of more exotic materials and I think that the detector array would be micro-bolometer based but there may be others.
Additionally the GOES satellites are geo-stationary which means that they can "look" at a hot spot long enough to detect enough energy for discriminatiion unlike GPS which cannot.
While it may be true that 'NOBODY, especially environmentalists, have "banned controlled burns" anywhere on the planet.' never the less they have been effectively halted in many venues. Two main reasons are: 1) Lack of funding - There's little funding for prescribed burns (US lingo) and 2) Agency and personal liability - If there is no chance the prescribed fire can escape it probably won't burn well enough to accomplish objective of the burn. Thus there is always the possibility of escape. Escaped fires are immensely expensive to the agency conducting the burn AND to the managers that signed off on the burn and the crew conducting the burn. If someone injured or dies then there can be criminal charges as well. In years past California had an insurance program to take care of the cost of escaped burns but that program is no more.
The old adage that "there's never enough money for fire prevention but there's always enough for fire suppression" was old 30 years ago and is still true today.
I wonder if she starts out any of her "coprolite 101" classes with "This is a coprolite, it's fossilized dung. You may think it's just old shit but it's my bread and butter."

>> Architects in the early 20th century came up with an interesting solution to this: use a third dimension, and install elevators. Now you can walk horizontally in two dimensions, and travel up/down, bringing a large company's employees all within relatively short distances of each other.
That crossed my mind but it's not as cool as Jobs' solution. On the other hand, not being a genius innovator, I think I'd like my office to be on the opposite side of the ring from the CEO's.
WIth a diameter of about 1/3 of a mile a collaborator will need to walk about 1/2 mile for a face to face in the other's office on the opposite side of the ring. Good exercise but perhaps a waste of time.

How about that! Some time around 1945-1948 my mother objected to me reading comics and I replied that there was a stamp/icon on then that said that some educational group approved the comics. She must have rolled her eyes. I had quit reading them before 1954. There was a great rise of "juvenile delinquency", especially in cities, at that time and "experts" came up with all sorts of reasons, completely untested reasons mostly. We now know that much if it was due to lead from leaded gasoline and from leaded paint in the environment.
Don't forget the minerals that will be left behind to clog the wall along with the mold. Locations that are dry enough for evaporative cooling to work are usually short of water, too, so this would be like a faucet continually running.
That's why it never worked before! Nobody thought about building a two-dimensional reactor!
That's assuming that it's rectangular solid, it's probably an ellipsoid.
I have porn in my home data center. What else would I have in it?
Schlock movies and forgettable juvenile music?
