Uber homes in on safety initiatives amid concerns - CNET

Uber is a ride-hailing service that pairs passengers with drivers via a smartphone app. Since its launch six years ago, the company has gone from a San Francisco-based startup to a multinational service in 295 cities and 55 countries. But with that rapid growth has come criticism about how the company handles safety. Over the last year, Uber has been dogged by allegations of drivers assaulting, raping and kidnapping passengers. The company has acknowledged it needs to improve its approach to security.

The challenges of using Facebook for research

However, the nature of Facebook as a mostly private network limits what can be learned from it. We were able to learn how news organizations and newsmakers use Facebook to get their message out and how users interacted with those messages. But this is a small sliver of the overall activity on Facebook and represents only a facet of the use of Facebook for local news. The majority of Facebook activity is still private and available only to Facebook itself. Even with just publicly available data, researchers face ethical and privacy concerns when deciding what to publish.

http://venturebeat.com/2015/03/26/amazon-launches-two-new-cloud-drive-unlimited-plans-11-99year-for-photos-and-59-99year-for-everything/

The plans focus on two specific scenarios. For those who have loads of photos, there is the Unlimited Photos plan that costs $11.99 per year. Then there’s the Unlimited Everything plan that, well, does what its name suggests, and costs $59.99 per year. There’s also a free three-month trial available to see how much “unlimited” space you actually need and for what. At any rate, with a monthly cost of $5, it’s almost worthwhile paying for the service irrespective of how much cloud-based storage you actually need.

New 3D NAND flash will triple capacity of SSDs, Intel and Micron say

Executives at the two companies said that by stacking the NAND they can greatly increase the capacity. The new 3D NAND technology stacks flash cells vertically in 32 layers to achieve a 256Gbit multilevel cell (MLC) and 384Gbit triple-level cell (TLC) die that fit within a standard package. Both say this approach will yield greater efficiency and lower the cost too.

Create apps for your quadcopter with 3D Robotics' free 'DroneKit' software

3D Robotics develops the open source software that powers a lot of home brew UAVs. Today it's introducing a new tool to the public: DroneKit , software that allows anyone to create apps for, well, drones! DroneKit works with any craft that uses 3DR's " APM " autopilot (a small device you add to your 'copter), and apps can be created for Android, web and standalone "companion" devices (that you then connect to your quadcopter). What can you do with these apps? So far, mostly the same things you can do with existing flight planning software (like 3DR's own Tower app ). That means controlling fly paths with waypoints, following GPS targets and access to all the telemetry of the drone. But, of course, now you can do it in new and creative ways . That's a good start, but its 3DRs promise to support the tool and keep adding new features that will change what we can do with these increasingly popular aerial craft.

4 Ways To Tell If You're Really Leading By Example

One of the best ways to cultivate influence among others is to focus on meeting the needs of others. This can be difficult. Instinctually, we can all be self-focused. Many of us arrive to work thinking about all the things we have to do in any given day to be effective. But if we make it a habit to spend 10-15 minutes a day doing something on behalf of someone else—such as listening, having an agenda-free conversation, thinking of what you can do to remove an obstacle for someone else—we are able to build a service-based leadership habit.

Periscope, Twitter's answer to Meerkat-style live-streaming, is now available

For everything it got right, Meerkat still looks like an app built in eight weeks — which it was. Periscope has been in development for more than a year, and the app arrives showing nice attention to detail. You sign in with Twitter, and the first thing you see is a list of streams that are currently live. Below it, you’ll see a list of recent streams. Not all can be played back — when you record yourself, you can stop your stream from being replayed with a single tap. But they save by default, and the result is an app that can actually be browsed.

Supernatural: "Paint It Black" Review - IGN

However, something about Rowena is off. Her flair sort of dilutes whatever her master plot is. At first the plan seemed to be making Crowley a better King of Hell but then there was getting revenge on the coven and that turned into manipulating Crowley's opinion of Sam and Dean. After she tortured Olivette tonight and learned about the Men of Letters, it seems she's going back to pushing the Sam and Dean topic. Let her figure out her evil plan, let her show off her skills -- just give her something else to do other than pouting at and nagging Crowley.

Arrow: "Suicidal Tendencies" Review - IGN

Despite the fact that I’ve tended to rate new episodes of Arrow higher than those of Flash in the past few weeks, I’m more concerned about the state of the former as we move closer to the season finale. Season 3 has struggled to develop a clear sense of purpose and direction. As I’ve said in the past, when you compare the state of this season to how the show was faring with the Deathstroke conflict last year, the overarching conflict hasn’t come together as neatly or elegantly. With that in mind, it was disappointing to have an episode like “Suicidal Tendencies” come along. This episode tried to split its focus between two completely different storylines, and in the end did neither enough justice.

Ashu Garg of Foundation Capital will talk with Doug Miliken, VP, Global Brand Development, Clorox, Jeremy Wacksman, VP, Marketing & Product, Zillow about the challenges facing both traditional and digital brands. How can CPG brands monitor digital attribution the way mobile-first businesses do? And should they? Can a strictly digital brand like Zillow learn a few new tricks from an old dog like Clorox?

The things end users do that drive security teams crazy

I overheard a call that came into the help desk and was amazed how angry and abusive this guy (internal staffer) was to the help desk. I stepped in and tried to remedy the situation. I walked through all of the issues with his desktop that would not start up. He was convinced that he had been hacked. Then he mentioned that the power light on his monitor was yellow. I paused, took a deep breath and asked him what color the light on his computer was. He responded "there are no f*** lights". I asked him to turn his computer on and he paused...cleared his throat...thanked us and hung up. He had a long chat with HR after.

NASA's Plan to Give the Moon a Moon | WIRED

NASA chose this mission concept over one that would’ve bagged an entire asteroid. In that plan, the spacecraft would’ve captured the space rock by enclosing it in a giant, flexible container. The claw concept won out because its rendezvous and soft-landing on the asteroid will allow NASA to test and practice more capabilities in preparation for a Mars mission, Lightfoot says. The claw would’ve also given more chances at grabbing a space rock, whereas it was all or nothing with the bag idea. “It’s a one-shot deal,” he says. “It is what it is when we get there.” But the claw concept offers some choices. “I’ve got three to five opportunities to pull one of the boulders off,” he says. Not bad odds. Better than winning that Pikachu.

The Americans: "Do Mail Robots Dream of Electric Sheep?" Review - IGN

And wow on Betty’s reply to Elizabeth saying that yes, her death would make the world a better place in the long run: “That’s what evil people tell themselves when they do evil things.” No, I don’t think Betty is meant to give an absolute declaration on Elizabeth as an “evil person”, but we’ve already seen her do terrible things for what she believes is a truly just cause, and it was unsettling (both for her and us) to see her actually be told that what she was doing was evil. All of which is to say, this entire tragic, tear-inducing storyline underlined what a terrific character Elizabeth is and how awesome Keri Russell is playing her.

All 650 Members of Parliament in the UK will receive an iPad Air 2 after the May election

Getting elected to British Parliament has an added bonus this year. According to  The Telegraph , all 650 Members of Parliament (MP) in Great Britain will be given an iPad Air 2 and a laptop after the May election. The House of Commons Commission says the new hardware will cost around £200,000 ($300,000) over the next five years. Each MP will be given a 16GB Wi-Fi + Cellular iPad Air 2, which costs £499 ($744). Apple's tablet was chosen by the commission in part because it's already popular among MPs — 209 members in the House of Commons possess an iPad, including Prime Minister David Cameron.

St. Paul considers CenturyLink's cable alternative

With CenturyLink eager to offer cable-like television service in the Twin Cities, the city of St. Paul is forming a cable franchise application committee to negotiate the particulars, and there are a lot of them. CenturyLink already provides landline phone, "normal speed" Internet and DirecTV satellite television services in St. Paul. The franchise agreement would allow the company to offer Prism TV -- an Internet-based pay-television option -- throughout the Twin Cities. "It's a pretty high-tech product, so we deliver it over fiber-optics, versus a cable cord," said Joanna Hjelmeland, a CenturyLink spokeswoman. "We would be a competitive alternative to cable." Prism's features include up to four or five split screens at once and a wireless box. "You can move your TV inside, or outside, or watch a cooking show in your kitchen, without being connected to the box," Hjelmeland said. The company submitted a letter to the St. Paul city clerk Jan. 9 indicating that it hopes to enter into a competitive cable franchise agreement with the city, similar to the agreement that St. Paul recently negotiated with Comcast.

Pilot Was Locked Out of Germanwings Cockpit Before Crash | WIRED

Investigators do have other data to work with. The radar flight path can provide clues as to how the aircraft was behaving, and if the pilots were trying to correct for a problem with the aircraft. The pattern and state of debris can reveal some of the story. Calculating the trajectory and impact angle of various parts can indicate the position of the jet in its final moments, for example. Close examination of wreckage can provide clues. Scorching or soot suggest a fire. Looking at whatever’s left of the cabin and cockpit will yield more information—if, for example, the oxygen masks were deployed.

RadioShack puts customer personal data up for sale in bankruptcy auction

There is precedent for allowing customer data to be auctioned off in bankruptcy proceedings. In 2011, the Federal Trade Commission allowed Borders to auction personal data if the same privacy policy applied, the buyer was in the same line of business, and the data was sold alongside other assets. Standard General, which plans to keep some RadioShack stores open, may try to argue that it’s putting the data to similar uses, Bloomberg reports.

The Galaxy S6 Edge Is Totally Beautiful—And Pointless | WIRED

On Wednesday morning, Samsung’s two new phones arrived at my desk. The Galaxy S6 and S6 edge are two of the most anticipated, most important devices of the year. They represent an entirely new design direction from Samsung, with glass and carefully machined aluminum where there was once dimpled plastic that looked a lot like a Band-Aid. They’re Samsung’s attempt to keep up with the iPhone, which has entered the big-phone market with no subtlety and lots of success. They’re almost certainly going to be enormously popular.

Sources: Magic Is Raising $12M From Sequoia At A $40M Valuation

Almost all on-demand delivery services already charge a delivery fee, and that includes some of the biggest players like Postmates, WunWun, GrubHub, and Seamless. That puts Magic in the position of having to add its own markup to every order, meaning Magic users are paying two premiums (the first is for the convenience of using an on-demand service, and the second is for the convenience of doing that via text).

React Native: Bringing modern web techniques to mobile

Today, even though no one is forced to use it, new web projects at Facebook are commonly built using React in one form or another, and it's being broadly adopted across the industry. Engineers are choosing to use React every day because it enables them to spend more time focusing on their products and less time fighting with their framework. It wasn't until we'd been building with React for a while, though, that we started to understand what makes it so powerful.

Facebook's Video API lets brands push more and more video into your News Feed

The bulk of these API updates have to do with control over viewership. Those who work with Facebook’s Video API can now restrict the audience of the video by age, gender, and location—for example, limited videos to people living on the East Coast to eliminate TV spoilers, or pushing a video out to users who are at least 18 years old. Also new is the ability to publish a video directly to a Page without distributing it in News Feed, and the ability to batch-upload a bunch of videos at once without having them all get pushed to News Feed at once—you can schedule videos, set a video to be featured on a Page, and program a video playlist.

Android Showdown: Samsung Galaxy S6 vs. HTC One M9

The new Galaxy S6 takes design critics head on with a bold new direction for Samsung's flagship phone. The chintzy plastics and awful faux-metal are banished in favor of genuine metal and glass. This year's Galaxy finally looks and feels like the premium, high-end smartphone it's supposed to be. One big change Samsung loyalists might take issue with is the now non-removable battery or microSD card slot. HTC has always hung its hat on design, so it should be no surprise that the One M9 is as luxe as its predecessors. In terms of design and feel, the S6 and M9 appear to be on as level a playing field as ever.

Both phones are coming to all major U.S. carriers on April 10. Pre-orders start on March 27.

Ikea's flat-pack refugee shelter is entering production

Measuring about 188 square feet, each shelter accommodates five people and includes a rooftop solar panel that powers a built-in lamp and USB outlet. The structure ships just like any other piece of Ikea furniture, with insulated, lightweight polymer panels, pipes, and wires packed into a cardboard box. According to Ikea, it only takes about four hours to assemble.

Apple TV adds CNNgo for live and on-demand news video

You're right, and I strongly suspect Tim Cook knows this based on his comments about watching TV being like going back in time. These "channels" are archaic and actually serve no current purpose other than the source of the content. A "CNN" channel only makes sense when you already know that is a news channel. But who cares if your favorite drama is on ABC, NBC, or whatever? For years content like this is searchable on iTunes. That's what people want, and they will actually pay for it. (Remember the good old days of Napster?)

Getting your money's worth from Cisco

If you've ever tallied your company's spend on Cisco products and compared it against what you spend with other telecom and IT suppliers, in most cases, it's as large or even larger. Yet this fact often sits below the radar in most shops because the vast majority of companies do not have a contractual arrangement directly with Cisco, and instead purchase the vendor's products and services through one or more value added resellers (VARs).
