HTTP/2 Finalized

An anonymous reader writes: Mark Nottingham, chair of the IETF HTTP working group, has announced that the HTTP/2 specification is done. It’s on its way to the RFC Editor, along with the HPACK specification, where it’ll be cleaned up and published. “The new standard brings a number of benefits to one of the Web’s core technologies, such as faster page loads, longer-lived connections, more items arriving sooner and server push. HTTP/2 uses the same HTTP APIs that developers are familiar with, but offers a number of new features they can adopt. One notable change is that HTTP requests will be ‘cheaper’ to make. … With HTTP/2, a new multiplexing feature allows lots of requests to be delivered at the same time, so the page load isn’t blocked.” Here’s the HTTP/2 FAQ, and we recently talked about some common criticisms of the spec.

Patent Troll Wins $15.7M From Samsung By Claiming To Own Bluetooth

An anonymous reader writes: A jury has upheld patent claims against Samsung and awarded the patent-holder $15.7 million. “The patents relate to compatibility between different types of modems, and connect to a string of applications going back to 1997. The first version of Bluetooth was invented by Swedish cell phone company Ericsson in 1994.” Lawyers for the plaintiff argue that the patents cover all devices that use Bluetooth 2.0 or later, so further cases could extend far beyond Samsung. Of course, the company that won the lawsuit wasn’t the one who made the invention, or the one who patented it. The company is Rembrandt IP, “one of the oldest and most successful” patent trolls.

Nanotech Makes Steel 10x Stronger

An anonymous reader writes: A new metal-making process currently in testing at oil fields uses nano-scale plating to make metals like steel as much as ten times stronger than they would be without it. “[The process] uses an advanced form of electroplating, a process already used to make the chrome plating you might see on the engine and exhaust pipes of a motorcycle. Electroplating involves immersing a metal part in a chemical bath containing various metal ions, and then applying an electrical current to cause those ions to form a metal coating. The company uses a bath that contains more than one kind of metal ion and controls how ions are deposited by varying the electrical current. By changing the current at precise moments, it can create a layered structure, with each layer being several nanometers thick and of different composition. The final coating can be up to a centimeter thick and can greatly change the properties of the original material.” Read more of this story at Slashdot.

Federal Study: Marijuana Use Doesn’t Increase Auto Crash Rates

An anonymous reader writes: After the legalization of marijuana in multiple states around the U.S., many are worried about a corresponding uptick in car crashes as people drive while under the influence of pot. But according to a new federal study (PDF) commissioned by the National Highway Traffic Safety Administration, those fears seem unfounded. They report that after adjusting for other factors (people who tend to drive after using marijuana also tend to be more crash-prone in general), there was no statistically significant increase in crash rates by drivers who tested positive for the drug. It’s still a bad idea to drive high, but driving drunk is far, far worse: “One substance was shown to have a major influence on crashes: alcohol. The study confirmed the enormous danger of drinking and driving, even after age and sex adjustment: drivers with a 0.05% blood-alcohol level were found to be twice as likely to be in a crash. For a person weighing 180 to 190 pounds, that could be a single can of beer, glass of wine, or shot of liquor. At 0.08% (two drinks), the likelihood is quadrupled, and at .20% (four drinks or more), the risk is higher by 23 times.” Read more of this story at Slashdot.

OpenStreetMap.org Gets Routing

An anonymous reader writes “Good news for OpenStreetMap: the main website now has A-to-B routing (directions) built in to the homepage! The OSM website offers directions which are powered by third-parties using OSM data, providing car, bike, and foot routing. OpenStreetMap has a saying: ‘What gets rendered, gets mapped’ – meaning that often you don’t notice a bit of data that needs tweaking unless it actually shows up on the map image. It will make OpenStreetMap’s data better by creating a virtuous feedback loop.” Read more of this story at Slashdot.

US Military Working On 3D Printing Exact Replicas of Bones & Limbs

ErnieKey writes The U.S. military is working with technology that will allow them to create exact virtual replicas of their soldiers. In case of an injury, these replicas could be used to 3D print exact medical models for rebuilding the injured patient’s body and even exact replica implants. Could we all one day soon have virtual backups of ourselves that we can access and have new body parts 3D printed on demand? Read more of this story at Slashdot.

Researcher Developing Tattoo Removal Cream

BarbaraHudson writes During tattooing, ink is injected into the skin, initiating an immune response, and cells called “macrophages” move into the area and “eat up” the ink. The macrophages carry some of the ink to the body’s lymph nodes, but some that are filled with ink stay put, embedded in the skin. That’s what makes the tattoo visible under the skin. Dalhousie Uiversity’s Alec Falkenham is developing a topical cream that works by targeting the macrophages that have remained at the site of the tattoo. New macrophages move in to consume the previously pigment-filled macrophages and then migrate to the lymph nodes, eventually taking all the dye with them. “When comparing it to laser-based tattoo removal, in which you see the burns, the scarring, the blisters, in this case, we’ve designed a drug that doesn’t really have much off-target effect, ” he said. “We’re not targeting any of the normal skin cells, so you won’t see a lot of inflammation. In fact, based on the process that we’re actually using, we don’t think there will be any inflammation at all and it would actually be anti-inflammatory.” Read more of this story at Slashdot.

US Gas Pump Hacked With ‘Anonymous’ Tagline

An anonymous reader writes Researchers at Trend Micro have uncovered a gas pump in the United States whose ID has been changed from ‘DIESEL’ to ‘WE_ARE_LEGION’ — the call-sign of the Anonymous hacking group. Following up recent revelations regarding the vulnerability of gas pump systems to online attackers, the researchers found 1, 515 completely unprotected gas pump monitoring devices via the Shodan device-based search engine. The report notes that the exposed devices are capable of being protected via six-digit pins, but this security measure is not being used. The report concludes: “Our investigation shows that the tampering of an Internet-facing device resulted in a name change. But sooner or later, real world implications will occur, causing possible outages or even worse.” Read more of this story at Slashdot.

With Insider Help, ID Theft Ring Stole $700,000 In Apple Gift Cards

itwbennett writes The Manhattan District Attorney’s office has indicted five people for using personal information stolen from around 200 people to fund the purchase of hundreds of thousands of dollars in Apple gift cards, which in turn were used to buy Apple products. “Using stolen information to purchase Apple products is one of the most common schemes employed by cybercrime and identity theft rings today, ” District Attorney Cyrus Vance said in a statement. “We see in case after case how all it takes is single insider at a company—in this instance, allegedly, a receptionist in a dentists’ office—to set an identity theft ring in motion, which then tries to monetize the stolen information by purchasing Apple goods for resale or personal use, ” he said.

A Smartphone Dongle That Will Tell You If You’ve Got STDs

After the hoverboard, there are few sci-fi inventions more worked-on than Star Trek’s tricorder. Portable, simple diagnostic machines have been promised for years — there’s even a $7 million prize for building one — but most designs are still years away from reality. Read more…
