New Full Duplex Radio Chip Transmits and Receives Wireless Signals At Once

Wave723 writes: A new chip by Columbia University researchers uses a circulator made of silicon transistors to reroute signals and avoid interference from a transmitter and receiver that share the same antenna. This technology instantly doubles data capacity and could eventually be built into smartphones and tablets. The chip enables them to work around the principle of Lorentz Reciprocity, in which electromagnetic waves are thought to always travel along the same path both forward and backward. Traditionally, electronic devices required two antennas — a transmitter and receiver — that took turns or operated on different frequencies in order to exchange signals.

Scientists Build Smallest, Single Atom, Working Heat Engine

William Herkewitz, writing for Popular Mechanics: Physicists have just built the smallest working engine ever created. It’s a heat-powered motor barely larger than the single atom it runs on. Designed and build by a team of experimental physicists led by Johannes at the University of Mainz in Germany, the single atom engine is about as efficient as your car at transforming the changing temperature into mechanical energy. While scientists have previously created several micro-engines consisting of a mere 10, 000 particles, Johannes’s new engine blows these out of the water by paring down the machine to a singular atom housed in a nano-sized cone of electromagnetic radiation. The project is outlined today in the journal Science. “The engine has the same working principles as the well-known [combustion] car engine, ” Johannes says. It follows the same four strokes; expanding then cooling, contracting then heating.There’s some confusion here. The article says it’s a “four-stroke” engine. But as we know, a four-stroke engine consists of an intake stroke, a compression stroke, a power stroke, and an exhaust stroke — things that the engine in the article doesn’t seem to have. The article doesn’t mention how a single atom is able to mimic all the effects of a combustion engine. Update: 04/15 18:24 GMT by M :The article appears to have been updated for clarification.

Man Deletes His Entire Company With One Line of Bad Code

Reader JustAnotherOldGuy writes: Marco Marsala appears to have deleted his entire company with one mistaken piece of code. By accidentally telling his computer to delete everything in his servers, the hosting provider has seemingly removed all trace of his company and the websites that he looks after for his customers. Marsala wrote on a Centos help forum, “I run a small hosting provider with more or less 1535 customers and I use Ansible to automate some operations to be run on all servers. Last night I accidentally ran, on all servers, a Bash script with a rm -rf foo/bar with those variables undefined due to a bug in the code above this line. All servers got deleted and the offsite backups too because the remote storage was mounted just before by the same script (that is a backup maintenance script).” The terse “rm -rf” is so famously destructive that it has become a joke within some computing circles, but not to this guy. Can this example finally serve as a textbook example of why you need to make offsite backups that are physically removed from the systems you’re archiving?”Rm -rf” would mark the block as empty, and unless the programmer hasn’t written anything new, he should be able to recover nearly all of the data. Something about the story feels weird. Read more of this story at Slashdot.

Microsoft Sues US Justice Department, Asks Court To Declare Secrecy Orders Unconstitutional

Todd Bishop, reporting for GeekWire: Microsoft is suing the U.S. Justice Department, asking a federal judge to declare unconstitutional a provision of U.S. law that lets the government keep Microsoft and other tech companies from informing their customers when investigators seek access to emails and other cloud data. The suit, filed moments ago in U.S. District Court in Seattle, targets Section 2705(b) of the Electronic Communications Privacy Act, which allows the government to seek and obtain secrecy orders preventing companies from letting their customers know when their data is the target of a federal warrant, subpoena or court order. Brad Smith, Microsoft’s president and chief legal officer, recently criticized the 30-year-old Electronic Communications Privacy Act as outdated during his testimony in February before the U.S. House Judiciary Committee — bringing along IBM’s first laptop, released the same year, to help illustrate his point.Microsoft argues that these “indefinite gag orders” violate the First Amendment rights to inform customers. Furthermore, the company adds that the law also “flouts” the Fourth Amendment, which requires the government to give a notice to the concerned person when his or her property is being searched or seized. “This is a First Amendment fight that needed to get picked and I’m glad Microsoft picked it. Just as in the real world with physical seizures, secrecy in digital seizures should be the exception and not the rule. Yet as the Microsoft complaint shows, it’s receiving thousands of law enforcement gag orders every year and more than two-thirds of them are eternal gags with no end data, ” said Kevin Bankston, internet freedom advocate and digital rights lawyer. “This is clearly unconstitutional, yet with so many orders per year, it makes sense to strike at the root with a facial challenge to the law rather than try and challenge them all individually. And based on previous similar cases around gag orders in national security cases, I think they’ll succeed in striking this overbroad law down.” Read more of this story at Slashdot.

HTC 10 With 5.2-inch QHD Display, Snapdragon 820 SoC, 12MP Camera Launched at $699

Dan Seifert, writing for The Verge: HTC is today formally announcing the 10, its flagship smartphone for 2016. The HTC 10 follows last year’s M9 and blends the design of the M series with the A9 that came last fall. HTC says it spent 12 months designing this phone and integrated feedback from its customers throughout the development process. The 10 has everything you might expect from a flagship Android phone in 2016. There’s a 5.2-inch, quad HD Super LCD 5 display that HTC says displays 30 percent more color than last year’s phone. The screen is covered in Gorilla Glass with curved edges that blend into the phone’s metal frame. You’ll be able to find out if that’s enough for HTC to compete when the phone ships next month for $699. One interesting feature, which separates HTC 10 from many other Android flagship smartphones, is support for AirPlay. The feature enables the smartphone to stream media content to an Apple TV.

Surveillance Cameras Sold On Amazon Found Infected With Malware

An anonymous reader shares a report on ZDNet: Security researcher Mike Olsen has warned that some products sold through the Amazon marketplace are harboring a dark secret — malware. Olsen said in a blog post that while scouring Amazon for a decent set of outdoor surveillance cameras for a friend, he came across a deal for 6 PoE cameras and recording equipment. The seller, Urban Security Group, had generally good reviews and was offering a particular Sony setup on sale. After purchasing the kit, Olsen started setting up the surveillance system, logging into the administrator panel to configure it. Upon investigation, Olsen found that the device was talking to a server with hostname Brenz.pl, which is linked to malware distribution. If the device’s firmware links to this domain, malware can be downloaded and installed, potentially leading to unlawful surveillance and data theft.Perhaps the company which made the device didn’t realize its source code was compromised. While the aforementioned incident should serve as a reminder to people on why they need to be wary of the product they are purchasing, this isolated occurrence doesn’t prove in any way that “plenty” of cameras on Amazon are also infected, as the article and the original blog post are subtly trying to imply.

Experts Crack Petya Ransomware, Enable Hard Drive Decryption For Free

Reader itwbennett writes: Petya appeared on researchers’ radar last month when criminals distributed it to companies through spam emails that masqueraded as job applications. It stood out from other file-encrypting ransomware programs because it overwrites a hard drive’s master boot record (MBR), leaving infected computers unable to boot into the operating system. Now, security experts have devised a method that, while not exactly straightforward, allows users to recover data from computers infected with the ransomware without paying money to cyber criminals. Folks over at BleepingComputer have confirmed that the aforementioned technique works. Read more of this story at Slashdot.

New Metal Foam Armor Obliterates Bullets To Dust On Impact

HughPickens.com writes: Discovery Magazine reports that researchers at North Carolina State University have developed a super strong armor material that literally turns bullets to dust upon impact. The armor plating is made in part from composite metal foams, or CMFs, which are both lighter and stronger than traditional metal plating used in body and vehicle armor. The armor — only an inch thick — features a ceramic strike face, Kevlar backing, and CMFs in the energy-absorbing middle layer. “We could stop the bullet at a total thickness of less than an inch, while the indentation on the back was less than 8 millimeters, ” says Afsaneh Rabiei. “To put that in context, the NIJ standard allows up to 44 millimeters indentation in the back of an armor.” CMFs are very effective at shielding X-rays, gamma rays and neutron radiation. Other applications include space exploration and shipping nuclear waste which both require a material to be not only light and strong, but also capable of withstanding extremely high temperatures and blocking radiation. A video shows a 7.62 x 63 millimeter M2 armor-piercing projectile that was fired using standard testing procedures established by the Department of Justice for evaluating armor types.

Every Voter In The Philippines Exposed In Massive Data Breach

schwit1 writes: “The database of the Philippine Commission on Elections has been breached and the personal information of 55 million voters potentially exposed in what could rank as the worst ever government data breach anywhere, ” according to Infosecurity Magazine. The magazine attributes an initial web site breach to Anonymous, who were reportedly trying to persuade the commission to enable more security features on their automated vote-counting system before upcoming national elections on May 9. A second group named LulzSec Pilipinas then later posted the entire voter database online. Trend Micro originally broke the story, writing that “Every registered voter in the Philippines is now susceptible to fraud and other risks after a massive data breach leaked the entire database of the Philippines’ Commission on Elections.” They report that the breached data even included 15.8 million fingerprint records, as well as 1.3 million records for overseas Filipino voters, including their passports’ numbers and expiration dates, all stored in plain text.
