At its Ryzen Pro event in New York City last month, AMD invited a French company called Qarnot to discuss how they're using Ryzen Pro processors to heat homes and offices for free. The company uses the Q.rad -- a heater that embeds three CPUs as a heat source -- to accomplish this feat. "We reuse the heat they generate to heat homes and offices for free," the company says in a blog post. "Q.rad is connected to the internet and receives in real time workloads from our in-house computing platform."
The idea is that anyone in the world can send heavy workloads over the cloud to a Q.rad and have it render the task and heat a person's home in the process. The two industries that are targeted by Qarnot include movies studios for 3D rendering and VFX, and banks for risk analysis. Qarnot is opting in for Ryzen Pro processors over Intel i7 processors due to the performance gain and heat output. According to Qarnot, they "saw a performance gain of 30-45% compared to the Intel i7." They also report that the Ryzen Pro is "producing the same heat as the equivalent Intel CPUs" they were using -- all while providing twice as many cores.
While it's neat to see a company convert what would otherwise be wasted heat into a useful asset that heats a person's home, it does raise some questions about the security and profitability of their business model. By using Ryzen Pro's processors, OS independent memory encryption is enabled to provide additional security layers to Qarnot's heaters. However, Q.rads are naturally still going to be physically unsecured as they can be in anyone's house.

According to new statistics released on Tuesday by Kaspersky Lab, a prominent Russian information security firm, 2017 is on track to beat 2016 -- and every year since 2011 -- in terms of the sheer number of computers infected with malware that installs mining software. From a report: So far in 2017, the company says it has detected 1.65 million infected machines. The total amount of infected computers for all of the previous year was roughly 1.8 million. The infected machines are not just home computers, the firm stated in a blog post, but company servers as well. "The main effect for a home computer or organization infrastructure is reduced system performance," Anton Ivanov, a security researcher for Kaspersky, wrote me in an email. "Also some miners could download modules from a threat actor's infrastructure, and these modules could contain other malware such as Trojans [malware that disguises itself as legitimate software]." Ivanov said that the firm doesn't know how much money has been made overall with this scheme, but a digital wallet for one mining botnet that the company identified currently contains over $200,000 USD.Read Replies (0)

An anonymous reader quotes a report from Motherboard: Government hackers were using a previously-unknown vulnerability in Microsoft's .NET Framework, a development platform for building apps, to hack targets and infect them with spyware, according to security firm FireEye. The firm revealed the espionage campaign on Tuesday, on the same day Microsoft patched the vulnerability. According to FireEye, the bug, which until today was a zero-day, was being used by a customer of FinFisher, a company that sells surveillance and hacking technologies to governments around the world. The hackers sent a malicious Word RTF document to a "Russian speaker," according to Ben Read, FireEye's manager of cyber espionage research. The document was programmed to take advantage of the recently-patched vulnerability to install FinSpy, spyware designed by FinFisher. The spyware masqueraded as an image file called "left.jpg," according to FireEye.Read Replies (0)

An anonymous reader shares a ZDNet report, which also has some clarification from Intel: It looks like you can add WiGig wireless docking to Intel's dustbin (along with IoT products axed earlier this summer), as the company has discontinued existing products using the 802.11ad wireless standard, according to Anandtech. [Since publishing this report, we've received a statement from Intel clarifying its WiGig support: "We continue to offer current versions of our 802.11ad products, such as the Intel Tri-band Wireless AC 18265 and Gigabit Wireless 10101R antenna module. We remain committed to WiGig and think it has exciting potential for a number of applications, including enabling VR to become wireless, mesh networking and as part of Intel's leading products for 5G."] WiGig was developed several years ago with faster speeds than then-current Wi-Fi standards, but because it relied on the 60GHz channel, its high throughput could only travel over short distances. As a result, it eventually became marketed as a feature for wireless laptop docking stations, and while it received some support from enterprise laptop manufactures like Dell and Lenovo, the technology didn't make a big dent against standard wired laptop docks.Read Replies (0)

An anonymous reader quotes a report from Bleeping Computer: Security researchers have discovered eight vulnerabilities -- codenamed collectively as BlueBorne -- in the Bluetooth implementations used by over 5.3 billion devices. Researchers say the vulnerabilities are undetectable and unstoppable by traditional security solutions. No user interaction is needed for an attacker to use the BleuBorne flaws, nor does the attacker need to pair with a target device. They affect the Bluetooth implementations in Android, iOS, Microsoft, and Linux, impacting almost all Bluetooth device types, from smartphones to laptops, and from IoT devices to smart cars. Furthermore, the vulnerabilities can be concocted into a self-spreading BlueTooth worm that could wreak havoc inside a company's network or even across the world. "These vulnerabilities are the most serious Bluetooth vulnerabilities identified to date," an Armis spokesperson told Bleeping Computer via email. "Previously identified flaws found in Bluetooth were primarily at the protocol level," he added. "These new vulnerabilities are at the implementation level, bypassing the various authentication mechanisms, and enabling a complete takeover of the target device." Consumers are recommended to disable Bluetooth unless you need to use it, but then turn it off immediately. When a patch or update is issued and installed on your device, you should be able to turn Bluetooth back on and leave it on safely. The BlueBorne Android App on the Google Play Store will be able to determine if a user's Android device is vulnerable. A technical report on the BlueBorne flaws is available here (PDF).Read Replies (0)
A New Way to Learn Economics

John Cassidy, writing for The New Yorker: With the new school year starting, there is good news for incoming students of economics -- and anybody else who wants to learn about issues like inequality, globalization, and the most efficient ways to tackle climate change. A group of economists from both sides of the Atlantic, part of a project called CORE Econ, has put together a new introductory economics curriculum, one that is modern, comprehensive, and freely available online. In this country, many colleges encourage Econ 101 students to buy (or rent) expensive textbooks, which can cost up to three hundred dollars, or even more for some hardcover editions. The project is a collaborative effort that emerged after the world financial crisis of 2008-9, and the ensuing Great Recession, when many students (and teachers) complained that existing textbooks didn't do a good job of explaining what was happening. In many countries, groups of students demanded an overhaul in how economics was taught, with less emphasis on free-market doctrines and more emphasis on real-world problems.Read Replies (0)

Innovation, fetishized by Silicon Valley companies and celebrated by business boosters, no longer provides the economic jolt it once did. From a report: In order to maintain Moore's Law -- by which transistor density doubles every two years or so -- it now takes 18 times as many scientists as it did in the 1970s. That means each researcher's output today is 18 times less effective in terms of generating economic value than it was several decades ago. On an annual basis, research productivity is declining at a rate of about 6.8 percent per year in the semiconductor industry. In other words, we're running out of ideas. That's the conclusion of economic researchers from Stanford University and the Massachusetts Institute of Technology. In a paper published this week through the National Bureau of Economic Research, "Are Ideas Getting Harder to Find?", economics professors Nicholas Bloom, Charles Jones, and John Van Reenen, and PhD candidate Michael Webb, defy Betteridge's Law of Headlines by concluding that an idea drought has indeed taken hold. "Across a broad range of case studies ... we find that ideas -- and in particular the exponential growth they imply -- are getting harder and harder to find," the authors declare in their paper.Read Replies (0)

At its event in Cupertino, California today, Apple unveiled the iPhone X to mark the 10th anniversary of the iPhone. It brings several new features including an edge-to-edge screen, Qi wireless charging, and Face ID. The Verge reports: Because of its edge-to-edge display, the iPhone has no place for a conventional home button, relying instead on a complex facial recognition system to unlock the phone. Called FaceID, the new system will replace TouchID, the home button sensor that's enabled fingerprint logins since 2013's iPhone 5S. Users can wake the phone by swiping up from the button instead of hitting the button. The same gesture will open the control panel once the phone is awake. The updated iPhone 8 will continue unchanged, including both the home button and TouchID. Apple also unveiled the iPhone 8 and 8 Plus, which are updated versions of the iPhone 7 and 7 Plus released last year. These new devices feature glass backs with support for wireless charging. The Verge provides some additional specs and features in its report: Apple has improved the display on the iPhone 8 line, adding the same True Tone technology it offers on the 10.5-inch iPad Pro to automatically adjust the screen based on the ambient light in the room to offer more accurate colors. Internally, Apple has upgraded the processor from the A10 Fusion found in the 7 to the A11 Bionic. It's a six-core chip with two performance cores that are 25 percent faster than the A10, and four performance cores that the company says are 70 percent faster that the old model. There's also a new Apple-designed GPU that's 30 percent faster, with the same performance as the A10 at half the power. On the camera front, there's a new 12-megapixel sensor on the iPhone 8 that is larger, faster, and finally has optical image stabilization. The iPhone 8 Plus also has new sensors, and offers f/1.8 and f/2.8 apertures now. The dual cameras on the 8 Plus also have a new "Portrait Lighting" feature to adjust the lighting for portrait shots. And Apple says that the improvements apply to video, too, with Apple executive Phil Schiller claiming that the new devices have the "highest quality video capture ever in a smartphone," with support for 4K/60fps video. Slow motion videos now support up to 1080p resolution at 240fps, doubling the the iPhone 7's 120fps option. The iPhone 8 will start at $699 for a 64GB model, while the 8 Plus will start at $799 for 64GB of storage. You can preorder these devices starting Friday, September 15th, and they will be released a week later on September 22nd. UPDATE 9/12/17: The iPhone X will be priced starting at $999 for the 64GB variant. Pre-order will be available October 27th with shipments starting November 3rd.Read Replies (0)

The first big product unveiling at Apple's Event at the Steve Jobs Theater in Cupertino, California was the Apple Watch Series 3 with built-in support for cellular. TechCrunch reports: Wireless cellular LTE connectivity provided by a built-in chip means the new Apple Watch will be able to stay connected even when it's not tethered to an iPhone, which is a huge step forward in terms of making it an independent mobile device. Pricing for the Series 3 Cellular starts at $399, and a version without cellular starts at $329. Pre-orders begin on September 15, and they'll be available on September 22. The new Apple Watch is visually quite similar to the existing version, with backwards compatibility with existing straps and bands. There's a new Blush Gold color to match the new iPhone color option, and a new ceramic Dark Gray for the higher-end models that joins the existing white. Plus, the cellular version sports that red crown for an extra bit of visual flare. The non-cellular version doesn't have the new red crown.
Inside, it has a new dual-core processor with 70 percent better performance, as well as a new W2 chip that improves Bluetooth and wireless connectivity and power efficiency. The cellular antenna is actually the display itself, and there's an electronic SIM card inside for connectivity. The device is the same physical size as the Series 2, despite adding everything needed for cellular and LTE connectivity -- though the back crystal is extended 0.25 mm, which is incredibly thin. It's still got GPS like Series 2, and it's swimproof, plus it packs in all-day battery life still.Read Replies (0)

Sergey Bratus, Research Associate Professor of Computer Science, Dartmouth College, and Anna Shubina, Post-doctoral Associate in Computer Science, Dartmouth College write: The real issue is that today's web-based email systems are electronic minefields filled with demands and enticements to click and engage in an increasingly responsive and interactive online experience. It's not just Gmail, Yahoo mail and similar services: Desktop-computer-based email programs like Outlook display messages in the same unsafe way. Simply put, safe email is plain-text email -- showing only the plain words of the message exactly as they arrived, without embedded links or images. Webmail is convenient for advertisers (and lets you write good-looking emails with images and nice fonts), but carries with it unnecessary -- and serious -- danger, because a webpage (or an email) can easily show one thing but do another. Returning email to its origins in plain text may seem radical, but it provides radically better security. Even the federal government's top cybersecurity experts have come to the startling, but important, conclusion that any person, organization or government serious about web security should return to plain-text email (PDF).Read Replies (0)

Depending on who you ask, Rotten Tomatoes is the reason some movies don't perform at the box office. From a report: Countless movie executives, including producers, have told Deadline and the New York Times that the number atop a movie's page on Rotten Tomatoes signifying whether the majority of critics enjoyed or disliked a movie rules the box office. Director Brett Ratner was quoted as saying "I think it's the destruction of our business" while others have called for its demise. According to research conducted by Yves Bergquist, director of the Data & Analytics Project at USC's Entertainment Technology Center, that's not correct. Bergquist collected data from 150 movies this year that made more than $1 million at the box office. Using those Box Office Mojo numbers and comparing them to the critic and audience score on Rotten Tomatoes, Bergquist then "looked at [the] correlation between scores and financial performance" to determine if there was a linear line that could be drawn between low scores and bad box office performance. Or, more simply, did a lower "rotten" rating on Rotten Tomatoes equate to box office woes? The short answer is no, it didn't. Bergquist's findings confirmed that of the 150 movies surveyed, there was only a 12 percent correlation between a movie receiving a bad score and not performing well at the box office. Summer films saw even less of a correlation, with seven percent of lower-scored movies not performing at the box office.Read Replies (0)
