Android users get malware with their apps

first_img The apps were discovered to contain malware, according to a report from Android Police. Before Google realized the problem, which was reported by a Reddit user, the apps containing malicious code were downloaded over 50,000 times before their removal.Once Google was made aware of the problem, it took them less than five minutes to yank all of the apps from the marketplace. Unfortunately, the apps had been up in the Android App Market for roughly four days before the problem came to light. This is one of the security concerns related to Google’s open approach to the app store. Individual apps are not examined by Google before they are posted to the App Market.The apps, which were copies of some of the most popular apps in the Android App Market, had been modified to contain a Trojan horse. The App publisher who posted these malicious code-containing apps, Myournet, manged to post 21 infected apps in total. The code, which Google described as a “root exploit,” is designed to steal all of the data on an infected Android-based device, and may possibly be able to re-purpose the phone without the user ever being aware.Users who have been infected by one of these app can expect to get some help from Google. They are currently working on a fix for the malicious code. (PhysOrg.com) — As new platforms make their way into the market there will always someone who is looking to exploit them for illegal or unethical ends. More proof of that fact has come today when Google was forced to removed a large number of apps from the official Android App Market.

The content is provided for information purposes only. (Phys.org) — A new lineup of 14 Ivy Bridge processors are out of the bag from Intel. Thursday’s announcement by Intel involves new processors for mobile computers and desktops, but special attention is focused on four of those processors, which are destined for the Ultrabooks market. Intel made Ivy Bridge news last month with an announcement of quad-core parts destined for high-end laptops and desktops. The newest crop includes dual-core parts catering to more market segments, Explore further Intel introduces first batch of Ivy Bridge processors © 2012 Phys.Org Citation: Intel lines up 14 Ivy Bridge processors (2012, June 2) retrieved 18 August 2019 from https://phys.org/news/2012-06-intel-lines-ivy-bridge-processors.html Of the group of processors, six are desktop-grade. The rest are mobile, and four are the ultra-low voltage. They will carry a U at the end of their name. The new processor announcement is well timed as days ahead of the planned debut of new Ultrabook devices powered by Ivy Bridge processors, which will make their debut at Computex Taipei 2012. Some Ultrabooks sporting Intel’s latest Ivy Bridge Core processors will start to go on sale, including models with touchscreens.The ultra-light computers carrying the Intel name will be promoted aggressively. Intel sources say that the number of Ultrabook type machines, about 11, on the market today, will grow to over 110 designs in the pipeline. Some of the touchscreen Ultrabooks will be convertible, whereas the laptops can be turned into tablets. To support success, Intel has had to invest on processor technology that can elevate Ultrabooks. Intel Ivy Bridge designers have improved battery life and they have enhanced some security features. Intel technologists also say that they have raised the bar on specs to define a device that can become a third-generation Intel Core-based Ultrabook device. A revised definition of what it takes to build an Ultrabook includes requirements affecting performance, mechanical design, battery life and processor component characteristics for an Ultrabook. The third-generation Intel Core Ultrabook devices wake up from deep sleep state to full use (keyboard interaction) in less than seven seconds and are able to wake from sleep mode fast. They will load and run favorite applications quickly. Ultrabook devices must offer at least five hours of battery life, while many meet the recommended level of eight hours-plus. Ultrabook devices based on the new processors must have either USB 3 or Thunderbolt technology to enable rapid transfer capabilities. Also, the Ultrabook systems use chip-level authentication similar to hardware tokens.last_img read more

Fujitsu unveils device that lets printed paper become interactive w video

first_img © 2013 Phys.org Explore further New smart e-book system more convenient than paper-based books More information: via Diginfo Recognizing that tablet computers and smartphones have not yet made real paper obsolete, engineers at Fujitsu have created a device that allows people to use printed products in ways they’ve become accustomed to doing with electronic media. The system works by utilizing standard computer cameras, an overhead projector, image processing and electronics to run it all. In practice, it looks like a cylinder, about two feet tall that sits on the edge of a table. At the top of the cylinder is an overhang that contains the electronics, cameras and projector. To use the system, a person lays a piece of paper—or even an open book—on the table and allows the system to recognize it, which appears to happen very quickly. Next, the user reaches out a hand and extends a single finger for using as an interactive device. The system scans the finger noting its size, orientation, and even its color. This is to allow it to differentiate it from all other objects on the table. Once the system learns all it needs to know about the finger, the user can use it to highlight text on the printed page, graphics or pictures. Dragging them off to the side causes the highlighted material to be captured as a single unit and held for later use. The system also recognizes web page addresses and highlights them automatically. Tapping them with the finger causes the associated web page to be opened and stored in the area next to the printed material. It can also overlay information over the top of the printed material if desired.The engineers at Fujitsu also added another separate feature to the system that allows a user to manipulate virtual 3D objects in virtual space using their fist. At the demonstration, reps for the company indicated that the system is not yet ready for sale, but plan to make it so sometime next year. They added that they believe such technology would be very useful as a demonstration device, for travel agencies, for example, or as a way to allow users to interact with and fill out forms at governmental offices.center_img (Phys.org) —Fujitsu Laboratories has unveiled a new twist in touch-screen technology—an overhead projector/camera device that turns printed pages into interactive media. Called the Fingerlink Interaction System, it lets users highlight text or images using a single finger then drag them to one side for future use; tap on web-links and have web pages open, or use their fist to animate virtual 3D objects.

Autonomous quantum error correction method greatly increases qubit coherence times

first_img In order to flip the qubits back to their correct states, physicists have been developing an assortment of quantum error correction techniques. Most of them work by repeatedly making measurements on the system to detect errors and then correct the errors before they can proliferate. These approaches typically have a very large overhead, where a large portion of the computing power goes to correcting errors.In a new paper published in Physical Review Letters, Eliot Kapit, an assistant professor of physics at Tulane University in New Orleans, has proposed a different approach to quantum error correction. His method takes advantage of a recently discovered unexpected benefit of quantum noise: when carefully tuned, quantum noise can actually protect qubits against unwanted noise. Rather than actively measuring the system, the new method passively and autonomously suppresses and corrects errors, using relatively simple devices and relatively little computing power.”The most interesting thing about my work is that it shows just how simple and small a fully error corrected quantum circuit can be, which is why I call the device the ‘Very Small Logical Qubit,'” Kapit told Phys.org. “Also, the error correction is fully passive—unwanted error states are quickly repaired by engineered dissipation, without the need for an external computer to watch the circuit and make decisions. While this paper is a theoretical blueprint, it can be built with current technology and doesn’t require any new insights to make it a reality.”The new passive error correction circuit consists of just two primary qubits, in contrast to the 10 or more qubits required in most active approaches. The two qubits are coupled to each other, and each one is also coupled to a “lossy” object, such as a resonator, that experiences photon loss. “In the absence of any errors, there are a pair of oscillating photon configurations that are the ‘good’ logical states of the device, and they oscillate at a fixed frequency based on the circuit parameters,” Kapit explained. “However, like all qubits, the qubits in the circuit are not perfect and will slowly leak photons into the environment. When a photon randomly escapes from the circuit, the oscillation is broken, at which point a second, passive error correction circuit kicks in and quickly inserts two photons, one which restores the lost photon and reconstructs the oscillating logical state, and the other is dumped to a lossy circuit element and quickly leaks back out of the system. The combination of careful tuning of the resonant frequencies of the circuit and adding photons two at a time to correct losses ensures that the passive error correction circuit can operate continuously but won’t do anything to the two good qubits unless their oscillation has been broken by a photon loss.” Journal information: Physical Review Letters © 2016 Phys.org One possible implementation of the logical qubit. The qubits are in the blue boxes and the resonators are in the red boxes. Credit: Kapit. ©2016 American Physical Society Explore further The new method can correct photon loss errors at rates up to 10 times faster than those achieved by active, measurement-based methods. In addition, the passive method can partially suppress noise, so that there are fewer errors in the first place. In its current version, the method can correct only one error at a time, so if a second photon loss occurs before the correction is complete, the method cannot fix the resulting error.All of this error correction leads to a significant increase in the qubit coherence time. The new method can improve this time by a factor of 40 or more compared to without any error correction, and this improvement is greatly needed in order to construct quantum computers. As Kapit explains, qubit coherence times are currently so short that millions of qubits would be required to build a useful quantum computer. Increasing the coherence times can reduce this number to something more feasible.In the future, Kapit plans to integrate the new passive method with active, measurement-based methods to create a hybrid quantum error correction strategy, and investigate how the two methods might work together.He is also currently working with an experimental team to try to build, test, and optimize the device in the next few years. More information: Eliot Kapit. “Hardware-Efficient and Fully Autonomous Quantum Error Correction in Superconducting Circuits.” Physical Review Letters. DOI: 10.1103/PhysRevLett.116.150501 (Phys.org)—It might be said that the most difficult part of building a quantum computer is not figuring out how to make it compute, but rather finding a way to deal with all of the errors that it inevitably makes. Errors arise because of the constant interaction between the qubits and their environment, which can result in photon loss, which in turn causes the qubits to randomly flip to an incorrect state.

Voices should tell a story

first_imgSonam Kalra, the gifted musician blends gospel numbers with hints of sufi music . The Sufi Gospel Project that took off last year is one such creation that perfectly presents this concept. She believes that the music they (the six members of the project) create transcends religions and faiths. We got talking to the vocalist and tried to know more about her. Read on…How would you define your musical philosophy?Musically, I think what appeals to me about voices is that they should be big voices and tell a story – that to me is what a voice should do, sing yes, but also speak, tell you a story without necessarily spelling it out.  Shobha Gurtu, Begum Akhtar and Ella Fitzgerald’s voices were like that- filled with stories that made you want to keep listening to them, for that one glimpse into their hearts, Also Read – ‘Playing Jojo was emotionally exhausting’their souls. What/Who inspires you?My greatest inspiration has been my parents, Aneeta and Surjit Kalra. I sing for them. I sing for God. It’s that simple.In our country, how easy (or difficult) is it to make a mark in the music scene? What do you think about the main issues are?Honestly, I think it’s a great time in India to be in  the field of music, there are so many live music venues and audiences as well as festivals. And technology and social media have made it so easy to put your music out there so really, I have no complaints. Also Read – Leslie doing new comedy special with NetflixTell us about your best tracksAsking me to tell you what my best track would be like asking a mother to choose which child she loves more, each one of the songs is something I have created with my musicians so how can I choose? I love each of them.What songs top your playlist right now?What I am listening to right now is Hum Dekhenge a composition sung by Iqbal Bano based on an  Urdu Nazmwritten by Faiz Ahmed Faiz, with a revolutionary theme. I recently composed a song for women’s rights (for One Billion Rising) based on another poem by Faiz Ahmed Faiz so I have been researching a lot of Faiz lately. What suggestions/advice would you have for newbies in music?The only advice I can give to anyone in life is that you should be true to yourself and what you believe in. Take risks, don’t imitate. Be the best you that you can be. You have to work hard, whatever you do, not just in the field of music.   How did you guys come together/start off?I first conceived of this project when I was asked to sing gospel music to commemorate the birth centenary of the Sufi Hazrat Inayat Khan at the Inayat Khan Dargah in Delhi. I had sung gospel in churches and at other music venues but for the Urz of Inayat Khan, I wanted to create a sound that blended the faiths. I belong to the Sikh religion and am often asked why I sing gospel. My answer is always the same – because God has no religion. It’s not a band but a genre of music that I have created. The Sufi Gospel Project is a genre of music that blends together the many voices of faith, through song and music.last_img read more
