A New Process Turns Sewage Into Crude Oil

Big Hairy Ian shares this report from New Atlas: The U.S. Department of Energy’s Pacific Northwest National Laboratory has found a way to potentially produce 30 million barrels of biocrude oil per year from the 34 billion gallons of raw sewage that Americans create every day… [T]he raw sewage is placed in a reactor that’s basically a tube pressurized to 3, 000 pounds per square inch and heated to 660 degrees Fahrenheit, which mimics the same geological process that turned prehistoric organic matter into crude oil by breaking it down into simple compounds, only…it takes minutes instead of epochs… The end product is very similar to fossil crude oil with a bit of oxygen and water mixed in and can be refined like crude oil using conventional fractionating plants. After six years of development, they’ve licensed the process for a $6 million pilot plant that’s expected to launch in 2018. Read more of this story at Slashdot.

Hackers hijack a Philips Hue lights with a drone

Surprise! The Internet of Things is a security nightmare. Anyone who was online a few weeks ago can attest to that. The massive internet blackout was caused by connected devices , and new research from white-hat hackers expounds upon those types of vulnerabilities. The target? Philips Hue smart lightbulbs. While they’ve been hacked in the past , Philips was quick to point out that it happening in a real-world situation would be pretty difficult. Digital intruders would need to already be on your home network with a computer of their own — the company claimed that directly attacking the lightbulbs wasn’t exactly feasible. But this new attack doesn’t require that sort of access. In fact, all it takes is tricking the bulbs into accepting a nefarious firmware update. By exploiting a weakness in the Touchlink aspect of the ZigBee Light Link system ( again! ), the hackers were able to bypass the built-in safeguards against remote access. From there, they “extracted the global AES-CCM key” that the manufacturer uses to encrypt and authenticate new firmware, the researchers write (PDF). “The malicious firmware can disable additional downloads, and thus any effect caused by the worm, blackout, constant flickering, etc.) will be permanent.” What’s more, the attack is a worm, and can jump from connected device to connected device through the air. It could potentially knock out an entire city with just one infected bulb at the root “within minutes.” “There is no other method of reprogramming these devices without full disassemble (which is not feasible). Any old stock would also need to be recalled, as any devices with vulnerable firmware can be infected as soon as the power is applied.” The result is that the hackers were able to turn lights on and off both from a van driving by a house and a drone flying outside an office building. For the home, the team was 70 meters (229.7 feet) away and caused lights to go on and off individually. The office building houses a few security companies including Oracle, and was hacked from 350 meters (1, 148 feet; about a quarter of a mile), and once under control, the lights started signaling “S.O.S.” in Morse code. “We used only readily available equipment costing a few hundred dollars, and managed to find this key without seeing any actual updates.” Not terrifying at all, right? The researchers say that they’ve contacted Philips and included all the details needed for a fix. Philips has confirmed the weaknesses and issued firmware updates to hopefully guard against this ever happening. Via: New York Times Source: Eyalro (1) , (2) (PDF)

Foxconn Testing Wireless Charging For iPhone 8

One of the first big secrets regarding Apple’s upcoming smartphone has been spilled. According to a report from Nikkei Asian Review, Foxconn, the firm responsible for assembling iPhones, is testing wireless charging modules for the iPhone 8. TrustedReviews reports: Citing ‘an industry source familiar with the matter, ‘ the report states the wireless charging feature could appear on the next Apple handset, but it depends whether the company can produce enough satisfactory units. The source told Nikkei: “Whether the feature can eventually make it into Apple’s updated devices will depend on whether Foxconn can boost the yield rate to a satisfactory level later on.” The yield rate refers to the ‘number of satisfactory units in the production of a batch of components, ‘ and if it’s found to be too low, the wireless charging feature could be left out of the iPhone 8 according to the report. It’s also claimed the wireless tech could make it into some versions of the iPhone 8 and not others. Nikkei is also reporting that Apple’s next gen smartphones are expected to arrive in three different sizes — 4.7-inch, 5-inch and 5.5-inch — all of which will come with glass-backed bodies. The Next Web reports: “Nikkei further suggests out of the three new iPhones will be a premium model with a curved edge-to-edge OLED display; the other two models will likely have standard LCD displays. Here’s what Nikkei’s source said: “Apple has tentatively decided that all the 5.5-inch, 5-inch and 4.7-inch models will have glass backs, departing from metal casings adopted by current iPhones, and Biel and Lens are likely to be providing all the glass backs for the new iPhones next year.

Why Apple and Microsoft Are Using Last Year’s Skylake Processors In Their New Computers

Apple released new MacBook Pros yesterday that feature Intel’s year-old Skylake microarchitcure, as opposed to the newer Kaby Lake architecture. Two days earlier, Microsoft did the same thing when it released the Surface Studio. Given the improvements Kaby Lake processors have over Skylake processors, one would think they would be included in the latest and greatest products from Microsoft and Apple. Gizmodo explains why that’s not the case: In the case of the new 15-inch MacBook the answer is simple. “The Kaby Lake chip doesn’t exist yet, ” an Apple rep told Gizmodo. Kaby Lake is being rolled out relatively slowly, and it’s only available in a few forms and wattages. The 15-inch MacBook Pro uses a quad-core processor that has no Kaby Lake equivalent currently. That particular laptop really does have the fastest processor available. The same goes for the Microsoft Surface Studio and updated Surface Book — both also use a quad-core Skylake processor with no Kaby Lake counterpart. But the Studio and Surface Book are also using much older video cards from the Nvidia 900 series. Nvidia has much faster and less power-hungry chips (the 1000 series) available based on the Pascal architecture. Microsoft’s reasoning for going with older video cards is nearly identical to Apple’s for going with a slower processor in its 13-inch MacBook Pro: the Nvidia 1000 series came out too late. The major intimation was that Kaby Lake and Pascal came so late in the design process that it would have delayed the final products if they’d chosen to use them. New technology, no matter how amazing an upgrade it might be, still requires considerable testing before it can be shipped to consumers. One minor bug, particularly in a system as engineered as the Surface Studio or MacBook Pro, can turn catastrophic if engineers aren’t careful. In the case of Microsoft, it’s frustrating, because that old GPU is significantly slower than the Pascal GPUs available. It’s a little less frustrating in Apple’s case, largely because of the old processor microarchitecture that Apple elected to shove into its new 13-inch MacBook Pro. Apple went with a new Skylake dual core processor that draws a lot of power — more so than any Kaby Lake processor available. It then uses all that extra power to ramp up the speeds of the processor. Which means it is capable of pulling off speeds that can actually match those of the fastest Kaby Lake processor out there. The only downside to this decision is battery life.

Windows 10 ‘Creator’s Update’ coming for free next spring

Even though the Surface line of convertible PCs has made Microsoft a hardware contender, its world still revolves around Windows 10. At today’s event, the company has revealed a lot of details about the next Windows 10 release, dubbed the “Creator’s Update.” That all starts with a new version of Paint it previewed earlier this month that’s far from version you may have created a pixelated doodle with. Instead, it allows you to scan objects from the real world and bring them into a 3D environment. “If we want to make 3D creation for everyone. It has to be as easy as taking a photo, ” Saunders says. The new app lets you scan real objects and get them into Paint as a full 3D object. She showed off the new Capture 3D tool, by walking slowly around a sand castle model with a smartphone and capturing it in full 3D. There’s also a new Community pane that allows you to find and pull in creations from other users. During the demo, Saunders pulled in a 3D cloud created by another user, and used it in montage featuring her daughters. She was able to then transform that into a complete 3D object and, naturally, share the whole thing on Facebook. Naturally, as this is Microsoft, the company showed how such 3D objects can be used in PowerPoint. Developing …

First New US Nuclear Reactor In 20 Years Goes Live

An anonymous reader quotes a report from CNN: The Tennessee Valley Authority is celebrating an event 43 years in the making: the completion of the Watts Bar Nuclear Plant. In 1973, the TVA, one of the nation’s largest public power providers, began building two reactors that combined promised to generate enough power to light up 1.3 million homes. The first reactor, delayed by design flaws, eventually went live in 1996. Now, after billions of dollars in budget overruns, the second reactor has finally started sending power to homes and businesses. Standing in front of both reactors Wednesday, TVA President Bill Johnson said Watts Bar 2, the first U.S. reactor to enter commercial operation in 20 years, would offer clean, cheap and reliable energy to residents of several southern states for at least another generation. Before Watts Bar 2, the last time an American reactor had fired up was in 1996. It was Watts Bar 1 — and according to the Atlanta Journal-Constitution, it cost $6.8 billion, far greater than the original price tag at $370 million. In the 2000s, some American power companies, faced with growing environmental regulations, eyed nuclear power again as a top alternative to fossil fuels such as coal and oil. A handful of companies, taking advantage of federal loan guarantees from the Bush administration, revived nuclear reactor proposals in a period now known as the so-called “nuclear renaissance.” Eventually, nuclear regulators started to green light new reactors, including ones in Georgia and South Carolina. In 2007, the TVA resumed construction on Watts Bar 2, according to the International Atomic Energy Agency. The TVA originally said it would take five years to complete. The TVA, which today serves seven different southern states, relies on nuclear power to light up approximately 4.5 million homes. Watts Bar 2, the company’s seventh operating reactor, reaffirms its commitment to nukes for at least four more decades, Johnson said Wednesday. In the end, TVA required more than five years to build the project. The final cost, far exceeding its initial budget, stood at $4.7 billion. Read more of this story at Slashdot.

‘Cultlike’ Devotion: Apple Once Refused To Join Open Compute Project, So Their Entire Networking Team Quit

mattydread23 writes: Great story about the Open Compute Project from Business Insider’s Julie Bort here, including this fun tidbit: “‘OCP has a cultlike following, ‘ one person with knowledge of the situation told Business Insider. ‘The whole industry, internet companies, vendors, and enterprises are monitoring OCP.’ OCP aims to do for computer hardware what the Linux operating system did for software: make it ‘open source’ so anyone can take the designs for free and modify them, with contract manufacturers standing by to build them. In its six years, OCP has grown into a global entity, with board members from Facebook, Goldman Sachs, Intel, and Microsoft. In fact, there’s a well-known story among OCP insiders that demonstrates this cultlike phenom. It involves Apple’s networking team. This team was responsible for building a network at Apple that was so reliable, it never goes down. Not rarely — never. Building a 100% reliable network to meet Apple’s exacting standards was no easy task. So, instead of going it alone under Apple’s secrecy, the Apple networking team wanted to participate in the revolution, contributing and receiving help. But when the Apple team asked to join OCP, Apple said ‘no.’ ‘The whole team quit the same week, ‘ this person told us.” Read more of this story at Slashdot.
