I don't see why a drone couldn't be fitted with a special receiver for a laser signal sent from a satellite. Pretty hard to jam a signal from above.A nuclear satellite...
Yeah, put a satellite (and a nuclear one, no less) on geo-stat orbit over Iran... to save a RC airplane model... makes perfect sense (if it's not geo-sync, most of the time the signal won't come from above)
I can't see a viable strategy for jamming laser UV or X-Rays. These types of lasers can even transmit through clouds.
What the hell are you smoking? UV is blocked by the clouds, dispersed by dust, bent/distorted by inhomogeneous atmosphere. As for the Xaser, you imagine them operating in a continuous beam? Sorry to disappoint, 1-100 pico-sec pulses is what you get - you don't have mirrors for X-ray frequency. Not to mention that after 1 to 15 m in air, X-ray is attenuated to approx 37%.
I don't see the problem. Religion should be a subject you learn about in school. So much the better if Jediism and FSMism are big enough to be included.
FSMism? Is there a church of the Finite State Machine?
Because the "believers" in the Flying Spaghetti Monster (blessed his noodliness) are pastafarians - or, if at a high enough degree of sainthood is attained, pirates.
If your instructor tells you "Do these problems yourself, without help from anyone else" and you and 10 others split them up, it's cheating.
Is it education and learning coming exclusively from an "do it yourself, don't share with others"? I wouldn't object to it during an exam (at least, not other objections than to the very idea of today's exams, but that's another story) but I surely do mind in the context of assignments.
Other than that... an interesting the choice of the "instructor" word. Without putting words into your mouth, I'd dire to say this is symptomatic for the today's "education" system: it is not tuned to create "educated persons", but "instructed persons"; it however sells the snake-oil that the two are equivalent.
What's more, they make no effort to hide their "enhanced group work" skills from their instructors. We've asked several of the students about this behaviour and have been told "that's how things work in China. It's commonplace there."
In regards with intellectual creation: a culture of sharing in clash with a culture of artificial scarcity?
...ed and meaningless "article". This is probably the laziest and most pointless story I've seen on/. Try debugging in alpha and beta versions more before releasing into the wild.
So fast to jump the trigger. Letting aside that you don't debug, but you fix the bugs discovered by testing (well, you may use a debugger, but that's not the only mean available), consider this:
Recession; meaning: short of money; meaning: less development resources available or available for shorter time.
Consequence: do what you can within the bounds of "Cheap, good and quick: pick any two" - it is going to be way more expensive on long term, but... try teaching this to CEO-es under pressure to show results to shareholders.
Apple could easily continue 60% growth rates year after year just from the growth the phone ALONE can give them
In 20 years Apple will have owned all the financial institutions and in 100 years the Earth crust will be covered by 1 meter of iPhones ALONE - never mind other iOS device like the iPad/touch.
It's simple - you add up the cost of outages (revenue and reputation), ops overhead (support staff and time lost using clunky UI's) and correcting mistakes caused by errors in the code, then you compare it against the cost of resolving the technical debt.
Hang on, buddy... that's already an overload for the sales/marketdroid single neuron... why should they care, as long as they get the commission? If the company goes busted, that's not their problem either... their CV will show how many zillions they made in sale, not their fault the company went under.
Nanoparticles are so small they are measured in nanometers (a nanometer is a millionth of a millimeter)
Except that they're off by several orders of magnitude. A nanometre is a billionth (short scale) of a metre: that is, 1/1000000000 (10^-9) metres.
Except the only "mistake" they did was using the millimeters to express the nanometer (instead of the meter) - as a consequence, metric system purists choke intellectually.
Nanoparticles are so small they are measured in nanometers (a nanometer is a millionth of a millimeter); many have diameters in the range of 5–200 nm. At that size, the particles are small enough to evade uptake by the liver and spleen, enabling them to stay in the bloodstream longer. They’re also able to take advantage of a unique opportunity: they can fit through the holes in the walls of the permeable, or “leaky,” blood vessels that tend to form in tumors. When nanoparticles are injected intravenously, they flow right on through normal blood vessels, which have tight walls without holes, but selectively diffuse through the permeable vessels out into tumors.
Targeting the nanotubes solely to cancer cells is the major challenge in advancing the therapy, Curley says. Research is under way to bind the nanotubes to antibodies, peptides or other agents that in turn target molecules expressed on cancer cells. To complicate matters, most such molecules also are expressed in normal tissue.
In her project, Angela aimed to design a targeted gold and iron oxide-based nanoparticle with the potential to eradicate cancer stem cells through a controlled delivery of the drug salinomycin to the site of the tumor.
All you need is a simple jammer that broadcasts over the entire spectrum that the enemy is using.
There's a lot more to jamming than that. Unless your transmitter is absurdly more powerful than the one you're trying to jam out, spread spectrum transmissions can be extremely difficult to jam.
Oh, well. What is the use of receiving clear instructions on how to navigate, if your positioning system is jammed?
China has more than enough coal for that. Australia's coal will be in trouble once China can build nuke plants cheaply.
Well, maybe... but then again... maybe not (note that 62% of China's coal imports is on coking coal, the rest of it being for steaming).
Australian iron ore miners will be OK, the uranium miners - maybe better.
...'sophisticated, adaptive applications.'... that allows a swarm of small deployed UAVs to be controlled...with easy-to-use app interfaces
Requirements lead to the need of a lot of "intelligence" be moved inside the app.
Meaning:
1. DARPA is scrapping the barrel for intelligent human operators (to pilot the UAV-es)
2. DARPA is naive enough to trust complex software be bug free and secure 3. both of the above
A bonus if the DARPA's choice for the OS platform is MS Windows.
A huge bonus if the resulted app is so sophisticated and easy-to-use that it can be operated directly by GWB, Obama, Michelle Bachman or... hang on... Vermin Supreme of Rockport, Mass. - without UAV-jockeys in between.

Pastafarians are just one state in the omniscient Finite State Machine.
I can't concur... pastafarians are closer to transition than to a state.

Dichroic filters usually reflect the unwanted portion of the light and transmit the remainder.

Re:The study has the most flaws
Why, was it written in Java?
It's simple - you add up the cost of outages (revenue and reputation), ops overhead (support staff and time lost using clunky UI's) and correcting mistakes caused by errors in the code, then you compare it against the cost of resolving the technical debt.

TFA is sparse on tech details. So how exactly nano-particles know if a cell is cancerous or not?
Some (very sparse) details on the GWU site
In her project, Angela aimed to design a targeted gold and iron oxide-based nanoparticle with the potential to eradicate cancer stem cells through a controlled delivery of the drug salinomycin to the site of the tumor.
Cure cancer, only make 100k
... and who owning the patent?
10 hamburgers per month?
It's too many already, I know. Hold your hope, my friend, have patience... maybe will go lower sometime.
oops. You win.
Not intended, wasn't a fight.
Sorry.
Don't... no worries, the Ozzie coal miners are safe in spite of Bill Gates ( long live Open Source and open cut coal mines ;) )
Cheers
Honestly a drone takeover requires you to be above it. They get control from satellites and AWAC's that are flying ABOVE Them.
Well, "at higher altitude" doesn't necessary equate with "above". What if, instead of jamming the control signal, the Iranians jammed the GPS signal?
There's a lot more to jamming than that. Unless your transmitter is absurdly more powerful than the one you're trying to jam out, spread spectrum transmissions can be extremely difficult to jam.
Oh, well. What is the use of receiving clear instructions on how to navigate, if your positioning system is jammed?
The majority of coal that China gets from Australia is NOT coking.
Uh?. Beg your pardon? I'd call 60% a majority.
China has more than enough coal for that. Australia's coal will be in trouble once China can build nuke plants cheaply.
Well, maybe... but then again... maybe not (note that 62% of China's coal imports is on coking coal, the rest of it being for steaming).
Australian iron ore miners will be OK, the uranium miners - maybe better.
Bad news for the Australian Coal industry.
But hey, if we are going to export Uranium to India, why not China too...
What, China doesn't need steel anymore?
but, somehow I wouldn't feel good when my code worked in this case
Would you feel better if your code wouldn't work (e.g. have some bugs or something) but would still be used?
... and no magnetic monopoles yet?
what could possibly go wrong!
