That's a big fleet of planes. Just think, one "not secret" program inside one bureau of one branch of our Federal Government controls 50 aircraft, and we're not even allow to know what this operation is called, as they smother the whole thing under shell companies.

Isn't having a giant government great? Lets give them more money and see what they do with it.

art blogs

Uh huh.

Art blogs.

Pretty much do exactly the opposite of anything advocated on art blogs and you're going the right direction.

Google ... started

The latest Android has icons are so abstract they are effectively meaningless. The clock looks like a pie chart; they can't even suffer the hour tick marks that might assist in conveying "clock." The "text" app is a huge left double quote — so out-of-context that it has no association with the concept of "communication." The Google Drive icon is a three color triangle that bears zero resemblance to any sort of storage concept. Basically you must read the label of every icon and slowly try to associate these pictorial abstractions to their actual purpose. In reality users are just memorizing the locations of these meaningless icons, and if you were to rearrange their locations they'd be totally lost.

It sucks. It's stupid. And I'm 100% certain there is a cabal of "art" fucks behind it.

Think of Stop signs

No. Don't think of Stop signs. Stop signs aren't trying to convey an association to anything. You can't buy and eat a box of "stops." Many, many road signs use useful pictographs to convey things; a vehicle skidding due to ice; immigrants hand-in-hand running across a road, the silhouette of a bounding buck.... GUI icons need to convey association; storage, trash, communication, people, news, dates and times, etc.

Trying to boil all these things down to abstract vector art is idiot.

+ - SourceForge assumes ownership of GIMP For Win, wraps installer in adware->

Submitted by Anonymous Coward
An anonymous reader writes: It appears that SourceForge is assuming control of all projects that appear "abandoned." In a blog update on their site, they responded saying in part "There has recently been some report that the GIMP-Win project on SourceForge has been hijacked; this project was actually abandoned over 18 months ago, and SourceForge has stepped-in to keep this project current. "

SourceForge is now offering "to establish a program to enable users and developers to help us remove misleading and confusing ads."

+ - Alloy Deforms, Springs Back Into Shape Millions Of Times->

Submitted by MTorrice
MTorrice writes: By adding a touch of cobalt to an alloy of titanium, nickel, and copper, an international team of researchers has come up with a shape-memory alloy film that can be deformed at least 10 million times and still snap back to its original shape. The finding represents a remarkable improvement on previous shape-memory alloys, which, at best, could withstand only a thousand deformations before succumbing to structural failure.

The current, top-of-class alloy is nickel titanium, which is used in stents to open blood vessels and as orthodontic wires.

I don't think concentrating on the detection problem is the best approach

Yeah, well word #2 in this story's subject is "Detecting," so I went with that. Silly me.

not only the drone but the pilot's location

Detecting the "pilot" is actually the hardest part. $200 buys a programmable autopilot that will drop a UAV on any GPS coordinate the batteries can reach — sans pilot. Signals can come from any radio system, including ubiquitous ones like cell towers, so good luck finding that needle in the urban haystack.

2 pound

You just pull that figure out of your butt?

Not that a 2 lbs craft is harmless, but 2 lbs is light. According to the FAA the upper limit for "recreational" UAVs is 55 lbs. It is easy to get into the 10's of lbs with big, extended range batteries, a high res camera, multi-axis gimbal, etc. Really easy. Whipping along at modest 60 mph you can cover 10-15 miles on today's batteries.

Anyone that can't see the potential of that is a fool.

by Tailhook (#49794793) Attached to: Why Detecting Drones Is a Tough Gig

The typical multirotor "drone" is necessarily built very lightweight; the electronics and motors are not typically shielded much at all. The brushless motors emit stupid amounts of RF energy due to unshielded motors, multiple banks of ESC's covered by nothing but heatshrink, etc. It shouldn't be particularly hard to spot a fast moving, localized source of RF noise at frequencies typical of multirotor motors.

Then there is heat. The ESCs and motors are HOT. Again, mass must be minimized so there is no easy way to hide that heat. A bright infrared spot zipping along at 50' altitude shouldn't be hard to detect.

For things that are piloted with FPV cameras there is a big video return signal coming off the craft. Due to antenna size this is usually some UHF frequency and fairly loud. The range of possible frequencies is vast, but in the real world there are a limited number of cost effective miniature transmitters available, so it isn't difficult to anticipate the likely frequencies.

Seems like there are a number of tell-tails that shouldn't be hard to exploit if you are serious about it have the means...

They *are* productive.

No, they are not. They export some commodities, but beyond that they add no value to anything. Their factories are shut because their labor laws and practices make them non-viable. No significant intellectual property is created there, despite their vaunted "free" education. Rampant, endemic corruption keeps investors out.

Do you understand that the Euro is zero sum?

I understand that people invent strange concepts such as that to rationalize their world view when reality fails to cooperate. Worse, I understand the people of Greece are prone to indulge such falsehoods, which doesn't bode well for their post-Euro future.

I am jsut stating that it should help.

Covering your weapons in mirrors is stupid and impractical. The "just put mirrors on everything LOLZ" trope your kind always trots out doesn't become more feasible just because you're naive enough to keep repeating it.

For a much cheaper price than such a lser system itself.

Defense is always more expensive that offence. It's easier to break things. That's why being wealthy is important to self preservation.

Hillary et al tell us we deserve more bennies and the "rich" need to pay their "fair share"... and the rest is so much noise from the `vast right wing conspiracy' that goes in one ear and out the other. As long you can stand there and tell people they deserve things they know they don't you can do anything you want. All else is forgiven.
