Don’t Sass Your Uber Driver – He’s Rating You Too

HughPickens.com writes David Streitfeld reports at the NYT that people routinely use the Internet to review services from plumbers to hairdressers but now the tables are turned as companies like Uber are rating their customers, and shunning those who do not make the grade. “An Uber trip should be a good experience for drivers too, ” says an Uber blog post. “Drivers shouldn’t have to deal with aggressive, violent, or disrespectful riders. If a rider exhibits disrespectful, threatening, or unsafe behavior, they, too, may no longer be able to use the service.” It does not seem to take much to annoy some Uber drivers. On one online forum, an anonymous driver said he gave poor reviews to “people who are generally negative and would tend to bring down my mood (or anyone around them).” Another was cavalier about the process: “1 star for passengers does not do them any harm. Sensible drivers won’t pick them up, but so what?” In response, some consumers are becoming more polite and prompt. “The knowledge that they may be rated is also encouraging people to submit more upbeat reviews themselves, even if the experience was less than stellar, ” writes Streitfeld. “When services choose whom to serve, no one wants to be labeled difficult.” The result may be a Barney world says Michael Fertik referring to the purple dinosaur who sings, “With a great big hug and a kiss from me to you/ Won’t you say you love me too.” Read more of this story at Slashdot.

Quantum Entanglement Can Now Be Performed on a Chip

The lure of quantum entangled computing is strong, as it can provide a means of impenetrable encryption —but the hardware has always been too bulky to make it practical. Now, though, researchers have shrunk the technology down to less than the width of a human hair, small enough to squeeze onto a chip. Read more…

US Army Releases Code For Internal Forensics Framework

An anonymous reader writes: The U.S. Army Research Laboratory in Maryland has released on GitHub a version of a Python-based internal forensics tool which the army itself has been using for five years. Dshell is a Linux-based framework designed to help investigators identify and examine compromised IT environments. One of the intentions of the open-sourcing of the project is to involve community developers in the creation of new modules for the framework. The official release indicates that the version of Dshell released to Github is not necessarily the same one that the Army uses, or at least that the module package might be pared down from the Army-issued software.

Wi-Fi Issues Continue For OS X Users Despite Updates

itwbennett writes: Although Apple has never officially acknowledged issues surrounding Yosemite and Wi-Fi connectivity, the company is clearly aware of the problem: Leading off the improvements offered in the update 10.10.2 update released Tuesday was ‘resolves an issue that might cause Wi-Fi to disconnect, ‘ according to the release notes. Despite this, Apple’s support forum was filled with tales of frustrated users. And Mac owners aren’t the only Apple users experiencing wireless connection failures after updating their OS. Wi-Fi connectivity issues have also dogged iOS 8 since Apple released the mobile OS on Sept. 17. Read more of this story at Slashdot.

Proposed Disk Array With 99.999% Availablity For 4 Years, Sans Maintenance

Thorfinn.au writes with this paper from four researchers (Jehan-François Pâris, Ahmed Amer, Darrell D. E. Long, and Thomas Schwarz, S. J.), with an interesting approach to long-term, fault-tolerant storage: As the prices of magnetic storage continue to decrease, the cost of replacing failed disks becomes increasingly dominated by the cost of the service call itself. We propose to eliminate these calls by building disk arrays that contain enough spare disks to operate without any human intervention during their whole lifetime. To evaluate the feasibility of this approach, we have simulated the behaviour of two-dimensional disk arrays with N parity disks and N(N – 1)/2 data disks under realistic failure and repair assumptions. Our conclusion is that having N(N + 1)/2 spare disks is more than enough to achieve a 99.999 percent probability of not losing data over four years. We observe that the same objectives cannot be reached with RAID level 6 organizations and would require RAID stripes that could tolerate triple disk failures. Read more of this story at Slashdot.

UHD Spec Stomps on Current Blu-ray Spec, But Will Consumers Notice?

An anonymous reader writes Details have emerged on the new UHD Blu-ray spec and players set to start shipping this summer. UHD promises resolutions 4X greater than Blu-ray 1080p as well as much higher data rates, enhanced color space and more audio options. But, will consumers care, and will they be willing to upgrade their HDTV’s, AV Receivers, and Blu-ray players to adopt a new format whose benefits may only be realized on ultra large displays or close viewing distances? The article makes the interesting point that UHD isn’t synonymous with 4K, even if both handily beat the resolution of most household displays. Read more of this story at Slashdot.

Microbots Deliver Medical Payload In Living Creature For the First Time

Zothecula writes: Researchers working at the University of California, San Diego have claimed a world first in proving that artificial, microscopic machines can travel inside a living creature and deliver their medicinal load without any detrimental effects. Using micro-motor powered robots propelled by gas bubbles made from a reaction with the contents of the stomach in which they were deposited, these miniature machines have been successfully deployed in the body of a live mouse.

The New Jamstik+ Is A Musician’s Best Friend

 As a wannabe guitarist, I find that the hardest thing to do is sit down and actually play guitar. When I first saw the Jamstik, a six-fret mini electronic guitar, I was impressed. It was about as big as a sub bun and featured strings that never had to be tuned. To play it you simply chorded and strummed as usual and you could transmit your MIDI-translated noodlings to a mobile app or your desktop. Read More

Office 2016 and Office for Windows touchscreens are due later this year

Word for Windows 10. These touch-optimized apps are separate from the desktop Office suite. 5 more images in gallery The Office tablet and phone apps for iOS and Android both ship with a touch-optimized subset of the features of the full flagship Office suite, and even though Microsoft is readying an Office release for Windows phones and tablets, the desktop version will still reign supreme. Microsoft says that the next version of the flagship suite, dubbed Office 2016, will be “generally available in the second half of 2015.” It will remain optimized for keyboards and mice. The touch-optimized Office apps for Windows 10 are still on their way, though, and Microsoft has shared some screenshots that show what the apps will look like on both phones and tablets. Word, Excel, PowerPoint, OneNote, Outlook Mail, and Outlook Calendar for Windows 10 (the official product names) unsurprisingly share a lot in common with the touchscreen apps for other platforms. Microsoft released Office for iPad in March of 2014 , and that UI has served as the foundation for all the tablet versions of the suite, including the still-in-beta Android version . The phone-sized versions of the apps look more like the new iPhone versions released in November , not like the limited versions that are currently available on Windows phones. The Outlook app for Windows 10 is something we haven’t seen on other platforms yet. Microsoft has released Outlook clients for iOS and Android, but they only support business-class Office 365 accounts and are more or less just wrappers for the standard Outlook Web client. The version for Windows 10 looks more full-featured, more closely resembling the desktop version of Outlook, at least in the three-column tablet view. Read 2 remaining paragraphs | Comments
