Flight 4590 Didn't Kill the Concorde; Costs Did

Flight 4590 Didn't Kill the Concorde; Costs Did:
pigrabbitbear writes "If the plane were around today — which some still fantasize about — it'd be like powering a stretch Hummer with dolphin blood. The airlines couldn't sell enough tickets on the small plane to even make up for the amount of fuel it needed to guzzle on its journeys, let alone cover maintenance for the technological marvel. (A Concorde's taxi to the end of a runway used as much fuel as a 737's flight from London to Amsterdam.) Customers were fine with ordinary travel times for a fraction of the airfare and the plane only took transatlantic journeys, because going over land was too disturbing. Too much noise."

Famous "star cradle" might have been destroyed long before we ever discovered it

Famous "star cradle" might have been destroyed long before we ever discovered it:


This is one of the most-famous astronomy photos in the world. Called "The Pillars of Creation" it was taken by the Hubble telescope in 1995 and shows massive columns of hydrogen gas and dust in the Eagle Nebula—7,000 light years from Earth. Part of why these are a big deal is that columns of dust and gas like this are places where stars form.

But here's a cool and/or disappointing detail I hadn't known about until today. Back in 2007, researchers took more images of this region of space using the Spitzer Space Telescope. These shots suggest that the Pillars of Creation might actually be long gone—destroyed thousands of years ago by a nearby supernova.

A striking image from Spitzer shows the intact dust towers next to a giant cloud of hot dust thought to have been scorched by the blast of a star that exploded, or went supernova. Astronomers speculate that the supernova's shock wave could have already reached the dusty towers, causing them to topple about 6,000 years ago.

However, because light from this region takes 7,000 years to reach Earth, we won't be able to capture photos of the destruction for another millenium or so.

Space is crazy, y'all.

DC police chief issues extremely excellent guidelines on citizens taking pictures of cops

DC police chief issues extremely excellent guidelines on citizens taking pictures of cops:


As part of a settlement with Jerome Vorus, who was ordered to stop taking pictures by DC cops, DC chief of police Cathy Lanier has issued guidelines to her officers on citizen photography of police activities. They are extremely excellent guidelines, too, as Timothy Lee writes in Ars Technica:




"A bystander has the same right to take photographs or make recordings as a member of the media," Chief Lanier writes. The First Amendment protects the right to record the activities of police officers, not only in public places such as parks and sidewalks, but also in "an individual’s home or business, common areas of public and private facilities and buildings, and any other public or private facility at which the individual has a legal right to be present."

Lanier says that if an officer sees an individual recording his or her actions, the officer may not use that as a basis to ask the citizen for ID, demand an explanation for the recording, deliberately obstruct the camera, or arrest the citizen. And she stresses that under no circumstances should the citizen be asked to stop recording.

That applies even in cases where the citizen is recording "from a position that impedes or interferes with the safety of members or their ability to perform their duties." In that situation, she says, the officer may ask the person to move out of the way, but the officer "shall not order the person to stop photographing or recording."

She also notes that "a person has the right to express criticism of the police activity being
observed."
There is more, and it's all excellent. We have the good folks at the ACLU to thank for helping Mr Vorus win his settlement with the DC police.

Hasbro Lazer Tag hands-on (video)

Hasbro Lazer Tag hands-on (video):
Hasbro Lazer Tag handson video
The NERF has been dropped, but Hasbro's Lazer Tag system is still the same awesome toy we got a taste of in February. The difference is, now they're retail ready. Individual blasters, complete with iDevice dock, will hit shelves in just over a week, while packages of two are scheduled for October 1st. The companion iOS app is already available through iTunes, but a rep from Hasbro still describes it as being in beta form (an update is on its way that will remove that tag and simplify the initial set-up). The same rep was also nice enough to swing by the Engadget compound and deliver us a pile of blasters to test ourselves, which we immediately took out for a test run in Washington Square Park. Head on past the break for some impressions and a taste of our "Lazer" battle royale.

The World's First 3D-Printed Gun

The World's First 3D-Printed Gun:
MrSeb writes "An American gunsmith has become the first person to construct and shoot a pistol partly made out of plastic, 3D-printed parts. The creator, who goes by the name HaveBlue and is an AR-15/M16 enthusiast, has reportedly fired 200 rounds with his part-plastic pistol without any sign of wear and tear. HaveBlue's custom creation is a .22-caliber pistol, formed from a 3D-printed AR-15 (M16) lower receiver, and a normal, commercial upper. In other words, the main body of the gun is plastic, while the chamber — where the bullets are actually struck — is solid metal. ... While this pistol obviously wasn't created from scratch using a 3D printer, the interesting thing is that the lower receiver — in a legal sense at least — is what actually constitutes a firearm. This means that people without gun licenses — or people who have had their licenses revoked — could print their own lower receiver and build a complete, off-the-books gun." Here come the illegal shapes. Note that the legal fiction of receiver-as-firearm is true in the U.S., but may not be in other jurisdictions, and that no gun license is required in most of the U.S. to purchase or possess a semi-automatic weapon.

Engadget's smartphone buyer's guide: summer 2012 edition

Engadget's smartphone buyer's guide: summer 2012 edition:
Engadget's smartphone buyer's guide summer 2012 edition
Despite the sweltering heat waves, our spirits are high at Engadget, and for good reason: it's time for our summer edition of the smartphone buyer's guide. Here, you'll find our top recommendations for the best smartphones across several US carriers, along with the best QWERTY and budget alternatives. In many ways, it's now easier than ever to find a world-class smartphone, but unless you've developed a strong brand preference, choosing one is likely more difficult than ever before. It's no secret that the HTC One X and Samsung Galaxy S III have firmly cemented themselves as the premier smartphones of the day, but if you're torn between the two, we'll reveal our preference in this latest installment.
Summertime also brought a bit of a shock, as Microsoft revealed that Windows Phone 8 apps won't be compatible with the current generation of Windows Phone hardware. For this reason, we've excluded all Windows Phone handsets from consideration in the latest buyer's guide. While the future of Microsoft's mobile platform looks incredibly bright, a purchase now would guarantee obsolescence in the short-term. Instead, all prospective Windows Phone purchasers must wait for the next generation of handsets to become available -- you'll regret it otherwise.
Naturally, there is no shortage of rumors surrounding the next Apple iPhone, and given the handset's current lack of LTE connectivity, the iPhone 4S is certainly showing its age. While cautious purchasers may choose to bide their time, the iPhone remains top-notch in many other respects, and its arrival at a number of prepaid carriers brought a breath of fresh air to an otherwise stagnant environment.
If you're curious to see how it all unfolded -- and we know you are -- join us after the break, where we round up the very best smartphones of the season.

RPG for water rockets

RPG for water rockets:






Japan's Marudai has brought forth upon this world a new form of water gun: a water rocket-propelled grenade launcher, which fires water balloons bottle rockets a great distance. As the machine-translated text says, "This toy is a toy and enjoy the recoil when firing injection.
Please observe the rules and manners play within the terms stipulated." Can't argue with that.



(Thanks, Fipi Lele!)









Olympic gold medals contain only 1% gold; would cost $25,000 if pure

Olympic gold medals contain only 1% gold; would cost $25,000 if pure:


The amount of gold in an Olympic gold medal has fallen to 1.34 percent, thanks to gold prices that recently peaked at $1,895 an ounce. At current prices, a pure 400g medal would cost about $25,000 to make, with a total bill of about $50m for the games.


"The last time the Olympic Games handed out solid gold medals was a hundred years ago at the 1912 Summer Games in Stockholm, Sweden," writes gold brokers Dillon Gage. "Gold medals were in fact only gold for eight years. The 1904 Olympics in St. Louis introduced the gold medal as the prize for first place."


The 2012 gold is 92.5 percent silver, 1.34 percent gold, and 6.16 copper, with IOC rules specifying that it must contain 550 grams of high-quality silver and 6 grams of gold. The resulting medallion is worth about $500. For the silver medal, the gold is replaced with more copper, for a $260 bill of materials.


The bronze medal is 97 percent copper, 2.5 percent zinc and 0.5 percent tin. Valued at about $3, you might be able to trade one for a bag of chips in Olympic park if you skip the fish.




New Mac Trojan Installs Silently, No Password Required

New Mac Trojan Installs Silently, No Password Required:
An anonymous reader writes "A new Mac OS X Trojan referred to as OSX/Crisis silently infects OS X 10.6 Snow Leopard and OS X 10.7 Lion. The backdoor component calls home to the IP address 176.58.100.37 every five minutes, awaiting instructions. The threat was created in a way that is intended to make reverse engineering more difficult, an added extra that is more common with Windows malware than it is with Mac malware."
