This Bullet Can Change Direction Mid-Air To Track Down Its Target

 

 

 

” The future of war is a laser-guided bullet that can change direction and hit targets at a distance of over one mile away.

  DARPA, the research arm of the Pentagon, has developed the EXACTO system to put a four-inch-long bullet with an optical laser sensor and an eight-bit central processing unit that can compute an algorithm to command electromagnetic steering to give the bullet its deadly precision.

  Unlike most rifle bullets, EXACTO has no spin. Instead, it travels like an electronic dart with fins that can guide it in mid-air.

  A sniper team can control the bullet after firing to ensure accuracy while compensating for weather, wind, target movement, and a range of other factors.”

Boeing Test Flies The Unmanned QF-16 Fighter

 

 

Boeing Pilotless F-16

 

 

 

 

” As a pilotless F-16 roared into the sky Sept. 19 at Tyndall Air Force Base, Fla., members of Boeing’s QF-16 team and the U.S. Air Force celebrated.

  The flight represented the first unmanned QF-16 Full Scale Aerial Target flight.  Put another way, fighter pilots now have an adversary for which to train against that prepares them like never before.

  Two U.S. Air Force test pilots in a ground control station at Tydall remotely flew the QF-16, which is a retired F-16 jet modified to be an aerial target. While in the air, the QF-16 mission included a series of simulated maneuvers, reaching supersonic speeds, returning to base and landing, all without a pilot in the cockpit.

“ It was a little different to see it without anyone in it, but it was a great flight all the way around,” said U.S. Air Force Lt. Col. Ryan Inman, Commander, 82nd Aerial Targets Squadron. “It’s a replication of current, real world situations and aircraft platforms they can shoot as a target. Now we have a 9G capable, highly sustainable aerial target.”

  Prior to the QF-16, the military used a QF-4 aircraft, which was a modification of the F-4 Phantom, a Vietnam-era fighter The modified QF-16 provides pilots a target that performs closer to many jets flying today.

  The QF-16s were all retired aircraft. Boeing retrieved them from Davis Monthan Air Force Base in Arizona and restored them for flight.

  Next up, live fire testing moves to Holloman Air Force Base, N.M. The military will ultimately use QF-16s for weapons testing and other aerial training.

  So far, Boeing has modified six F-16s into the QF-16 configuration.

  To see the QF-16 make its first flight, watch the video. To see highlights from the cockpit video, click the link (pilotless F-16) in the written story.”

Twitter Takes Steps To Frustrate NSA, Other Government Snoops

 

 

Up Yours NSA

 

 

” Twitter announced Friday that it’s joining other tech companies in implementing “perfect forward secrecy.” While many online services already encrypt user communications and other data, this form of encryption ensures that snoops—we’re looking at you, National Security Agency—who break through the encryption get access to only a snippet of data, rather than everything belonging to a user. Even where a warrant is involved, perfect forward secrecy has the potential to limit intrusions, rather than acting as an open-ended skeleton key.

The Electronic Frontier Foundation’s Parker Higgins describes how perfect forward secrecy works:

 How can perfect forward secrecy help protect user privacy against that kind of threat? In order to understand that, it’s helpful to have a basic idea of how HTTPS works in general. Every Web server that uses HTTPS has its own secret key that it uses to encrypt data that it sends to users. Specifically, it uses that secret key to generate a new “session key” that only the server and the browser know. Without that secret key, the traffic traveling back and forth between the user and the server is incomprehensible, to the NSA and to any other eavesdroppers.”

 

 

 

 

 

 

 

 

Batteries To Become A Thing Of The Past

 

 

 

 

” Disposable and rechargeable batteries that power tens of millions of portable electronics could become obsolete over the coming decades as new technologies come to market that can convert ambient energy into usable electric power, new research shows.

The concept, known as “energy harvesting” (EH), is becoming more viable as technology firms bring products to market that can transform electromagnetic, thermal and mechanical energy sources into power that can be stored and used.

“In the near future, EH technology will power an increasing number of consumer and industrial products that are untethered or need to become disconnected from electrical outlets,” researchers with Navigant Energy said in a recent published report on the technology. Moreover, EH systems “offer an inexpensive and compact way to power portable electrical devices that in many cases rely heavily on batteries.” ”

The “CG-42″ Gauss Machine Gun Is An Eight-Stage, Full-Auto Coilgun

 

 

 

” “A coilgun is a linear motor. Electronics hobbyist James Paul has developed a great mathematical model of a basic linear motor on his website Coilgun Systems. Please read about his model here. A key conclusion drawn from the model is that coils become more efficient as projectile speed increases. This conclusion rules out a single-stage coilgun as a good design because full power is dumped up front when the projectile is still moving slowly. A much better design uses multiple, lower power coils to distribute the acceleration over a longer distance so less energy is wasted during the initial slower portion of the acceleration. As the projectile speeds up, subsequent coils become increasingly efficient so adding more coils and lengthening the gun improves efficiency and increases muzzle energy. That means an efficient, powerful coilgun will be long and have as many stages as possible.”

All Hail The Beer Drone

 

 

 

 

” Revellers at a South African outdoor rock festival no longer need to queue to slake their thirst — a flying robot will drop them beer by parachute.

After clients place an order using a smartphone app, a drone zooms 15 metres (50 feet) above the heads of the festival-goers to make the delivery.

“Every time it drops a parachute a crowd of 5,000 cheers,” he said.”

SS Gairsoppa: 61 Tons of Silver Found in Odyssey Exploration

 

 

 

” Odyssey Marine Exploration Inc. recovered 61 tons of silver this month from the SS Gairsoppa, a World War II shipwreck lodged nearly three miles below the surface of the Atlantic Ocean off the coast of Ireland.

Odyssey recovered 1,574 silver ingots weighing a total of about 1.8 million ounces from the SS Gairsoppa, the Tampa, Florida-based deep-sea salvage company said in a statement Monday. The 412-foot (126-meter) British cargo ship was torpedoed by a German U-boat in February 1941, according to Bloomberg.

The metal was worth about $630,000 when the Gairsoppa was sunk and about $36 million at today’s prices. Odyssey has recovered a total of 2,792 ingots from the wreck, about 99 percent of the insured silver reported to be aboard when the vessel sank.”

5 Terrifying Smartphone Hacks You Won’t Believe Are Possible

” … a cadre of supervillains (ahem, “researchers”) from Georgia Tech decided to create a program that turns your innocent-looking smartphone into a nosy little asshole that sits there spying on your every keystroke. Passwords, email messages, IMVU sex chats — your phone could be eavesdropping on all of it.

  Sometimes we fail to appreciate the fact that today, right now, we’re living in a sci-fi universe. The smartphone is a miracle of mathematics and engineering genius, converting a little over 4 ounces of inert matter into a Star Trek-level wondercomputer. But the downside of storing your entire world inside an ass-pocket-dwelling supercomputer is that there are always those who are itching to turn that technology against you in ways you’d never expect, like …

#5. Your Phone’s Tilt Sensor Can Sense What You’re Typing on Your Computer

 
As you clack away on the keyboard, your phone’s accelerometer can pick up the tiny impacts resounding through your desk and, based on the distance of the keys from the phone, mathemagically deduce which keys you’re stroking.

  Phones with motion sensitivity on the level of an iPhone 4 can guess what you’re typing with up to 80 percent accuracy. And this clever bit of spyware can easily Trojan horse its way onto your phone as part of an otherwise trustworthy-looking app, since it doesn’t arouse your tinfoil-hat suspicions by asking for permission to use your camera or microphone.”
