Sony releases experimental Firefox OS ROM for Xperia E smartphone

Sony was one of the first major companies to announce their support for new operating system from Mozilla Firefox only a couple of days ago, but we had no idea that it had something in the works. Today the Japanese company launched an experimental Firefox OS ROM for developers to use on your smartphone ultra-low-end E Xperia.

The announcement shows that Sony is serious about operating system support and web-based will give developers a head start in working with Mozilla. Of course, Sony expects something in return – valuable community feedback.
A post on Sony developer blog gives readers an introduction to Firefox OS and highlights the architecture behind the new mobile platform. There are steps to help users in the process of flashing Firefox OS for their devices and Xperia. As always, you should understand that unlocking the bootloader may void the warranty of the device.

Once installed, you’ll probably want to spend more time reading the post as Sony outlines some key steps and links to many resources to help you get started. Your second stop would probably be the Mozilla Developer Network, as they have a wide range of documentation on how to write an application and details about emulators, privileged access model and debug statements.

It is worth noting that while the ROM is designed for developers, anyone with a smartphone Xperia E can download and take the plunge. Just make sure you know what you’re getting yourself into.

Time Warner says there is no demand for residential gigabit Internet

Google made ​​headlines last summer when he turned his first self-gigabit integrated Internet services available only to the lucky residents of Kansas City. While enthusiasts across the country continue to be envious of the 1.000 Mbps download and upload speeds that locals have enjoyed for more than six months, not everyone believes there is a market for this type of connection.

During a speech at the Conference of Morgan Stanley Technology today, Time Warner Cable CFO Irene Esteves downplayed the impact that Google Fiber is having on consumers. The executive said Time Warner was in the business of delivering what consumers want and stay a little ahead of what they think they want.

From now on, she said the company simply does not see the need to offer speeds similar to the average consumer. Residential customers have reportedly shown little interest in its top level Internet package. He noted, however, that already offer speeds of 1 gigabit for business customers – demonstrating at least they have the ability to do so.

That does not mean that Time Warner completely discarded the idea of ​​offering similar speeds to residential customers in the future. Esteves said that if Google has applications that require such speeds and no need for it, they build their product base to deliver too.

Until then, it seems that Time Warner customers and virtually everyone else will have to make do with existing speed grades until there is a real need – or Google decides to expand to other cities.

Application of the urine sample allows users to detect diseases with iPhone

Ever thought a smartphone could detect what was in the urine? Well, now you can. A new iPhone application developed by MIT entrepreneur Ingawale Myshkin, unveiled at the TED conference this week, allowing people to take urine samples with your mobile device.
Obviously, the mixture of urine and electronics do not mix, so this application instead uses the smartphone’s camera to determine what is in the urine. Nicknamed Uchek, the user application involves urinating into a cup, putting a urinalysis strip color coded in the cup, making the picture of the results, and then let the application do its magic.

iPhone-Pee-Pee
Uchek can detect up to 25 diseases, including diabetes, urinary tract infections, and pre-eclampsia. Can also measure levels of glucose, protein, ketones, and more. According to Wired, 1,200 samples of tests showed that the application was more accurate than humans interpret color-coded strips.
Ingawale goal is to help people become more aware of what health problems they may have or to monitor their conditions. Ideally, to provide additional information to a physician.
“The idea is to get people closer to their own information,” said Ingawale at the TED conference yesterday, according to Wired. “I want people to understand better what is going on with their bodies.”
Uchek is working its way through the approval process and Ingawale Apple is also working on an Android app, according to Wired. The application will cost 99 cents and users can buy a pack of strips and a user guide with color code for $ 20.

Using space telescopes to measure the black hole distortion

An innovative X-ray telescope operated by NASA, working in conjunction with a satellite of the European Space Agency, has been measured directly the rotation of a supermassive black hole lurking at the heart of a distant galaxy, researchers said on Wednesday .
The observation confirms the predictions of Albert Einstein’s theory of gravity capacity of general relativity with respect to twist and distort the structure of the cosmos and gives astronomers a powerful new tool to investigate the evolution of galaxies and black holes that now appear to be a common, if not necessary feature.

“The results we are announcing today is that, for the first time, we can definitely play features seen in the X-ray emission from a supermassive black hole and because the hole’s gravity is incredibly strong,” said Fiona Harrison, a researcher Main Nuclear Spectroscopic Telescope Array NASA or NuSTAR, X-ray telescope mission.
“The amazing thing about this observation is that we can see the curvature and torsion of space-time, the black hole distorts the very fabric of our universe. This distortion allows us to measure how fast the black hole is spinning.”
The galaxy in question, known as NGC 1365, is 56 million light years from Earth. The black hole in the center of the galaxy is 2 million times more massive than the sun.
By definition, black holes are not directly visible because their gravity is so intense that electromagnetic radiation can escape. But can be detected by illuminating radiation generated as gas particles and dust are sucked and heated to extreme temperatures.
The material falling into a black hole can form an accretion disk of debris spiral into the hole’s event horizon, the point defined by body mass and gravity beyond which nothing, not even light, can escape . Once an object crosses the event horizon, is lost forever in the known universe.
To measure the rotation of the black hole at the center of NGC 1365, the data was combined NuSTAR satellite observations with XMM-Newton of the European Space Agency, which is sensitive to low-energy X-rays.
The overlap allowed researchers rule out alternative explanations, resulting in a remarkable three days of observation that “solving a problem of two decades of life,” said Harrison. “Now we can say that the characteristics of the observed X-ray colors from black holes can definitely be used to measure the rotation of the black hole.”
In this case, the spacecraft studied X-rays reflected from the accretion disk around the black hole at the center of NGC 1365. Harrison said that the rotational energy was equivalent to the output of a billion stars over billions of years.
Asked if he could translate that into a more easily understandable speed, said “black holes are really weird …. It’s not like we can paint a small dot in the black hole, the event horizon, for example, and watch it rotate around a certain speed.’s probably more accurate to think of the amount of energy captured rotation, if that makes sense. ”
For at least one reporter, it was tough sledding. So Harrison offered an alternative explanation:
“We really spinning black holes twist and distort space-time,” she said. “If you were standing near the event horizon of the black hole in particular, you would have to turn around, because its twists spacetime, would be turning around once every four minutes just to stand still.”
Regardless of amazing physics involved, the ability to directly measure the rotation of the supermassive black holes gives astronomers a potentially powerful tool for the study of galaxy evolution.
“We know that today most, if not all, galaxies have a supermassive black hole at its center,” said Arvind Parmar, director of Astrophysics and Fundamental Physics at the European Space Agency. “The one in the center of our galaxy, the Milky Way, for example, weighs as much as four million suns.
“We believe that these black holes were born when the universe was only 10 percent of its current age. And when they were born, weighing only 20 to 30 times the mass of the sun. The real question is, how they grow from these small objects supermassive black holes we see today? ”
There are at least two possibilities. Black holes can grow by accumulation, ie, by sucking in surrounding material, or by collisions, when a black hole actually merges with another.
Accretion can cause rapid rotation while mergers of black holes can lead to different rates depending on the orientations of the holes colliding. The ability to measure the rotation could help astronomers determine which process is more common and the effect it has on the evolution of the galaxy.
“Even with these two wonderful missions, we can only measure the spins of these black holes in nearby galaxies bright,” said Parmar. “What I really like to do is to extend these studies to the more distant universe and see how the average rates of change in black hole spin with cosmic time.
“And this would allow us to investigate the importance of accumulation and the importance of the merger in the creation of the universe we see today,” he said. “It would help us understand why the universe looks as it does today.”

Bitcoin virtual currency reaches record after swap deal

Bitcoin has staged a dramatic comeback in the last two months, more than twice its value against the dollar at the time and is trading at record levels.
The virtual currency was trading above $ 32 per share today, after languishing in their teens to mid-January. The record was reached on the same day that Mt. Gox, the world’s largest Bitcoin exchange, agreed with CoinLab to manage operations in the U.S. stock market and Canada.

bitcoinexchange_610x238
Bitcoin emerged in 2009 as a coin peer-to-peer intentionally avoided the prying eyes of the officials responsible for enforcing the law. To acquire Bitcoins, users access to sites transfer exchange real currency, as the U.S. dollar, the digital option.
However, after struggling to get into the U.S. market, the expected Japanese trade agreement with the startup based in Seattle, which has a partnership with Silicon Valley Bank and $ 500,000 in venture capital funds , increase customer confidence.
“There are two main difficulties Bitcoin exchange clients who have traditionally faced: banking problems to the underlying exchange, and security of their currencies,” wrote Peter CoinLab Vessenes CEO in a company blog post announcing the partnership. “Since we believe in Bitcoin, we would like to solve these problems.”
The currency has experienced a rollercoaster ride over the past two years, establishing its previous record of $ 31.90 in June 2011 before falling to $ 2 later that year. Its exchange rate began to improve in mid-November, when the popular WordPress blog platform announced it will begin accepting Bitcoin payments for improvements such as custom designs and presentations without advertising.

Windows 8 $15 upgrade registration ends Thursday

Registration for the Windows 8 $15 upgrade offer expires this Thursday.

Those of you who just bought a PC with Windows 7 Windows 8 can score for just $ 15, but you will have to register by the end of Thursday.

To encourage interest in its latest operating system, Microsoft cooked a couple of deals last year’s update.
The first allows any user of Windows 7, Vista, XP or upgrade to Windows 8 for $ 40. The agreement ended January 31.

The second allows people who bought a PC with Windows 7 between June 2 last year and January 31 this year that Windows 8 Pro for just $ 15. Despite having expired last month, you can still register for it, but you will have to act in this Thursday, Feb. 28.

The registration process asks for your contact information, as well as the make and model of your computer with Windows 7, the retailer, and the date of purchase. The process can also request your license key Windows 7.

Assuming your PC is fine, then you receive an email with a promo code and a link to the update of Windows 8. The download link Windows 8 Update Wizard, which runs on your PC with Windows 7 to pay for the product and install the software.
A FAQ provides more details about the upgrade offer to Windows 8. People bump into problems with the process you can contact Microsoft Customer Support via the update page offer support.

What if you want to take advantage of the offer of $ 15, but do not want to upgrade to Windows 8 at this time?
You can download the update and simply store the installation files on a USB stick or burn them to a DVD from an ISO file. You can then install the update at any time and on any PC you want. One of my previous articles explained the process for creating installation media of Windows 8.

When exactly does the registration expires? A Microsoft representative told  that the Web site registration and redemption coupon code will continue to work until 28 February worldwide. That gives people until midnight on Friday to complete the process.

After cutting, Windows 8 jumps in the prices of virtually everyone – $ 120 for the regular edition and $ 200 for the Pro version Only students will still be able to score a discount.
So even if you are on the fence about the new operating system, those of you who qualify for the $ 15 offer may want to enroll in it, while there is still time.

Snapdragon 800 devices to feature Quick Charge 2.0, Voice Activation

Qualcomm Snapdragon processor details his next 800 at CES last month, but apparently I left a couple of key features in secret. Now, with Mobile World Congress just around the corner, the company is willing to share a little more with a blog post announcing 2.0 load faster and voice activation.

The first of these features is the natural evolution of the fast charge current 1.0 Qualcomm technology available on Snapdragon devices like the Galaxy S III, Nexus 4, and 920 Lumia. In short, the version 2.0 is said to load devices 75% faster than those without the technology, an improvement over the 40% figure announced by Qualcomm for quick load 1.0. The technology requires a charger optimized and baked at 800 Snapdragon, but is not exclusive of hardware-based Qualcomm. 2.0 Fast charging will be offered as a separate circuit for other companies to use and could charge even more demanding laptops up to 60W of power.

qualcomm-liquid-lead
To put things in perspective Qualcomm says its own laboratory tests showing tablets usually have more than 7 hours to charge were able to reach full charge in less than 3 hours with 2.0 fast charge.

In addition, the company announced that devices using Snapdragon processor 800 will always be in a low-power voice activation feature that allows users to wake up your phone with a personalized voice command. The feature is said to be adapted to the voice of each device owner and works even in standby mode or plane. Once the device is “awakened” function will activate your phone’s voice assistant for hands-free control.

Qualcomm says that there are currently more than 55,800 development Snapdragon-based devices, with hardware expected to land sometime in the second half of 2013 or early 2014.
