US edges closer to energy independence

EIA The net energy consumption of the US has held fairly steady for nearly 20 years. Over the past decade, however, there’s been a large increase in production of energy within the US. As a result, the US government’s energy figures for the first half of this year show that the differences between production and consumption have dropped to the lowest level in 29 years. This represents a net drop in energy imports by 17 percent compared to the same period a year earlier. According to the Energy Information Agency, the boost in energy production came from a variety of sources. Natural gas was the largest, accounting for just over half of the annual increase. Coal accounted for another quarter, renewable energy for 12 percent, and petroleum for eight. The EIA also notes that energy use this year was unusually high due to the intense cold that hit most of the nation in the first few months of 2014. The vast majority of the country’s imports come in the form of petroleum products and crude oil. These imports have been decreasing as new sources of oil are tapped and automotive efficiency standards are tightening. Refined petroleum products remain the largest US energy export; smaller quantities of coal and natural gas are also shipped overseas. Read 1 remaining paragraphs | Comments

Blue LEDs given Nobel Prize in physics

Nobel Prize Committee Each year, roughly a quarter of the electricity we generate goes to lighting. For decades, that lighting came in the form of an incandescent light bulb, which produced 16 lumens for every Watt it was fed. Fluorescent bulbs are roughly five times as efficient, but recent LEDs do nearly 19 times better than incandescents, producing 300 lumens for each Watt. The first LEDs date back to 1907, but it’s only recently that their incredible efficiency has been brought to bear on the lighting market. One of the key holdups was our inability to generate a broad spectrum of colors. Specifically, we couldn’t make white light because we lacked the ability to produce blue LEDs. Now, the Nobel Prize in Physics is being given to three materials scientists who overcame this roadblock. The people receiving the honor are Isamu Akasaki and Hiroshi Amano, both faculty at Nagoya University in Japan, and Shuji Nakamura, now of UC Santa Barbara, who did much of his key work while at Nichia Chemicals, a small company in Japan.

At 650% interest, that online payday loan is a steal

Fraud and Abuse Online: Harmful Practices of Inernet Payday Lending Online payday loan operators threaten their customers, promote loans designed for long-term indebtedness, and charge exorbitant interest rates, according to a study by the Pew Charitable Trusts. “Lump-sum loans online typically cost $25 per $100 borrowed per pay period—an approximately 650 percent annual percentage rate,” Pew said . The report, ” Fraud and Abuse Online: Harmful Practices in Internet Payday Lending ,” (PDF) comes a month after the Federal Trade Commission halted an only payday scheme that the government said “allegedly bilked consumers out of tens of millions of dollars by trapping them into loans they never authorized and then using the supposed ‘loans’ as a pretext to take money from their bank accounts .” Read 7 remaining paragraphs | Comments

Fans raise cash to help phone phreaker John Draper, aka Cap‘n Crunch

Aaron Getting An online fundraiser for legendary phone phreaker John Draper , better known as Cap’n Crunch, has passed its target $5,000 in just three days .  Draper himself doesn’t even know who started the fundraiser, but the money is intended to help with his medical bills. According to a recent blog post , he suffers from both degenerative spine disease and C. Diff, an inflammation of the colon . I want to thank with the bottom of my heart for an anonymous person for setting me up with qikfunder…. http://t.co/mwzDLLRpHH — John Draper (@jdcrunchman) September 25, 2014 In conjunction with others in the late 1960s and early 1970s, Draper figured out that a toy whistle given out in boxes of Cap’n Crunch cereal emitted a tone at 2600 Hertz. By pure coincidence, that happened to be the tone AT&T used to reset its trunk lines. As a result, Draper became a legend in the nascent world of phone phreaking, a predecessor to early personal computer hacking.

Comcast seeks to fix awful customer service, admits “it may take a few years”

Comcast executive Charlie Herrin is aiming to improve Comcast’s legendarily poor customer service. Comcast After months of getting bashed for treating customers poorly, Comcast today said it’s going to make improving customer service its “number one priority.” But the company admitted that “it may take a few years before we can honestly say that a great customer experience is something we’re known for.” Neil Smit, CEO of Comcast’s cable division,  wrote today  that Comcast’s customer service hasn’t kept up with Comcast’s focus on “product innovation,” technology, and content. “But this is only one half of the customer experience equation. The other half is operational excellence in how we deliver service,” he wrote. “The way we interact with our customers—on the phone, online, in their homes—is as important to our success as the technology we provide. Put simply, customer service should be our best product.” A longtime Comcast executive is being called upon to fulfill that goal. Smit announced the promotion of 15-year Comcast veteran Charlie Herrin to a new role as senior VP of customer experience. Herrin previously was senior VP of product development and led design of X1, Comcast’s new TV user interface. Read 5 remaining paragraphs | Comments

Update: Bug in Bash shell creates big security hole on anything with *nix in it

Mac OS X Mavericks is also a *nix, and also vulnerable to the Bash bug. Sean Gallagher Update: The Bash vulnerability, now dubbed by some as “Shellshock”, has been reportedly found in use by an active exploit against web servers. See Ars’ latest report for further details. A security vulnerability in the GNU Bourne Again Shell (Bash), the command-line shell used in many Linux and Unix operating systems, could leave systems running those operating systems open to exploitation by specially crafted attacks. “This issue is especially dangerous as there are many possible ways Bash can be called by an application,” a Red Hat security advisory warned. The bug , discovered by Stephane Schazelas , is related to how Bash processes environmental variables passed by the operating system or by a program calling a Bash-based script. If Bash has been configured as the default system shell, it can be used by network–based attackers against servers and other Unix and Linux devices via Web requests, secure shell, telnet sessions, or other programs that use Bash to execute scripts.

Apple releases iOS 8.0.1 with HealthKit, keyboard, iPhone 6 fixes

iOS 8.0.1 fixes a handful of bugs with the new update. Andrew Cunningham Apple has just released iOS 8.0.1, the first update to the new operating system that reached the public last week . The update is available through iTunes or as an over-the-air update for any device that runs iOS 8—the iPhone 4S or newer, iPad 2 or newer, and the fifth-generation iPod Touch. Though it comes just a week after iOS 8’s release, the 8.0.1 update fixes a wide-ranging list of problems. Apple has fixed the bug that was keeping HealthKit-compatible apps from working, and it corrected a problem where third-party keyboards could be toggled off after entering a passcode. The company also addressed photo library access for third-party apps, “unexpected cellular data usage when receiving SMS/MMS messages,” the Ask To Buy feature of Family Sharing, something keeping ringtones from being restored from iCloud backups, and “a bug that prevented uploading photos and videos from Safari.” Those updates are available for all devices, but the new iPhone 6 and 6 Plus get one specific fix that is meant to make the Reachability feature more consistent.

Reversible, tiny, faster: Hands on with the USB Type-C plug

Megan Geuss SAN FRANCISCO—Last week, Ars met up with several representatives of the non-profit USB Implementers Forum (USB-IF) to check out some of the first USB Type-C connectors off the assembly lines. The Type-C specification was announced in December and finalized in August , and it’s set to bring a number of improvements to its predecessors, in addition to being smaller than the Type-A USB plugs we’re familiar with today. Considering how many USB Type-A devices are still being actively built out there (over 4 billion USB-compatible products are made each year), this smaller, reversible connector represents a significant jump. Jeff Ravencraft, President and COO of USB-IF, told Ars that USB-IF wanted a connector that worked equally well for large and small devices. “We also understand that yeah the consumer maybe has some trouble with putting in that cable connector,” he added of the Type-C’s new-found ability to be plugged in right-side up or upside down, like Apple’s Lightning connector. The new Type-C connector is also slightly bigger than its proprietary cousin, with Type-C sized at approximately 8.4mm by 2.6mm and Lightning coming in at 7.7 mm by 1.7 mm. Unlike the reversible Lightning, but similar to USB connectors before it, the USB Type-C connector has a mid-plate inside the receptacle that the plug surrounds when it’s inserted.

Hack runs Android apps on Windows, Mac, and Linux computers

The official Android Twitter app running on Mac OS. Ron Amadeo If you remember, about a week ago, Google gave Chrome OS the ability to run Android apps through the ” App Runtime for Chrome .” The release came with a lot of limitations—it only worked with certain apps and only worked on Chrome OS. But a developer by the name of ” Vladikoff ” has slowly been stripping away these limits. First he figured out how to load  any app on Chrome OS, instead of just the four that are officially supported. Now he’s made an even bigger breakthrough and gotten Android apps to work on  any desktop OS that Chrome runs on. You can now run Android apps on Windows, Mac, and Linux. The hack depends on App Runtime for Chrome (ARC), which is built using Native Client , a Google project that allows Chrome to run native code safely within a web browser. While ARC was only officially released as an extension on Chrome OS, Native Client extensions are meant to be cross-platform. The main barrier to entry is obtaining ARC Chrome Web Store, which flags desktop versions of Chrome as “incompatible.” Vladikoff made a custom version of ARC, called ARChon , that can be sideloaded simply by dragging the file onto Chrome. It should get Android apps up and running on any platform running the desktop version of Chrome 37 and up. The hard part is getting Android apps that are compatible with it. ARC doesn’t run raw Android app packages (APKs)—they need to be converted into a Chrome extension—but Vladikoff has a tool called ” chromeos-apk ” that will take care of that, too.

Facebook acknowledges news feeds are bad at news, vows to improve

Facebook’s News Feed pays attention to trending topics, right, but news feeds have lately seemed to be lacking in news. Following criticism of the lack of current events in Facebook news feeds, Facebook has announced tweaks to its algorithms meant to help surface timely content. The company plans to do this by giving more value to posts that get interactions, such as likes and comments, and pushing posts when that activity seems to be cresting. In the blog post announcing the changes, Facebook wrote that it often prioritizes posts about “trending” topics that appear in the chart of hashtags posted on the right side of users’ homepages. Facebook also places higher value on posts according to how many interactions (likes, comments, shares) they receive. But as things are, some users have noted that Facebook seems to miss news waves , or is late to them, as with the fatal shooting of Mike Brown and the related protests that played out over weeks in August. When Facebook’s curation methods didn’t acknowledge those events, users noticed the news vacuum in their news feeds. Read 1 remaining paragraphs | Comments
