What is NFC and How it Can Create a Revolution in Changing Our Daily Lives

You all might have listened about NFC and might be you would be curious to know more about it.NFC or Near Field Communication is a new short range tool that works on wireless frequencies.It connects by any NFC antennae enabled phone to a reciever usually a feet away.By using this technology a consumer can just wave his smartphone for paying at retail locations.Still there are many challenges to safeguard the payment procedure or we can say that this technology is not fully baked.
It makes your life easier and more convenient as it can make transactions,exchange digital content and connect electronic devices with just a tap.
A standards-based connectivity technology, NFC harmonizes today’s diverse contactless technologies, enabling current and future solutions in areas such as:
  • Access control
  • Consumer electronics
  • Healthcare
  • Information collection and exchange
  • Loyalty and coupons
  • Payments
  • Transport
Developers can learn more about NFC in the section on interoperability.

Key Benefits of NFC

NFC provides a range of benefits to consumers and businesses, such as:
  • Intuitive: NFC interactions require no more than a simple touch
  • Versatile: NFC is ideally suited to the broadest range of industries, environments, and uses
  • Open and standards-based: The underlying layers of NFC technology follow universally implemented ISO, ECMA, and ETSI standards
  • Technology-enabling: NFC facilitates fast and simple setup of wireless technologies, such as Bluetooth, Wi-Fi, etc.)
  • Inherently secure: NFC transmissions are short range (from a touch to a few centimeters)
  • Interoperable: NFC works with existing contactless card technologies
  • Security-ready: NFC has built-in capabilities to support secure applications
NFC uses loosely coupled inductive circuits to exchange power and/or data over a short distance (usually about four cms.

7 Things You Should Know About Google Music | Google News

Google just made its music cloud service, Google Music, available to all, and it’s mostly self-explanatory. You can just Go to the Google Music and and start uploading or purchasing music that you can then listen to on your computer, or on your Android phone, Google TV, or iPhone. Just like iTunes, right? Well, not really. Maybe it’s not so straightforward after all its a Google Venture, don’t expect it to be so simple.
If you went online today, you might have Come across this image, see its footer, it states, NEW – Introducing Google Music..

Here are a few pointers that may help clear out some of the possible sources of confusion:

1. It can automatically back up iTunes and most other music flies. When you set up the service, you can tell it to upload your iTunes library, your Windows Media Player library, or any file folders you designate. The service supports more file types than competitors iTunes and Amazon Cloud Player. This includes not just the MP3 and AAC formats those support, but also WMA, OGG, and FLAC. The latter are saved as 320 Kbps, even if your originals are of higher quality.

2. It’s two separate sites. Google Music is the player and library, but you buy music on the Android Market site—whether or not you ever use any Android device. From the Google Music site, you can also download an app, Music Manager, that scans your PC or Mac for music files and upload it to your cloud-based music locker. The Android Market is where you browse, preview, and purchase new music, which then appears on your Google Music pages or in your Android Music app.

3. You can’t download songs to another computer unless you bought them on Google Music. iTunes Match and Amazon Cloud Player let you download stored music to any computer or compatible mobile device.

4. Some Android devices fully support it, some don’t. There is, of course, an Android app, but that hasn’t yet been updated with all the new features, and some phones and tablets still don’t see music in the Android Market app yet. The whole point of Google Music is to finally give Android mobile users an equivalent to the iTunes services enjoyed by iPhone and iPad users. Google states that this will be updated within days, but it’s unclear which phones and tablets’ Android versions will be updated on what schedule. Some Android phones and plans, starting with T-Mobile, will even let you pay for music through your phone bill.

5. There’s no official iPhone app, but works on iOS devices. The Google Music site is even formatted well for iPhone screens. You can listen to any music in your Google Music cloud locker and even buy music from the separate Android Store, but you can’t back up music on the iOS device to Google Music. Nor can you download music bought in the Android Music store to the iPhone directly (see #1 for how to do it indirectly).

6. There’s tons of free music. But you need to give Google your credit card information even for the free stuff. This could be a concern to those who worry about Google profiling them.

7. You can only share purchased songs to Google+. If you do so, anyone following your Google+ profile will be able to stream the full song once. A Buy button is prominently displayed.

Symbian Carla and Donna, the two new versions of Symbian:

Nokia on the developer’s day at mexico announced the next two Symbian versions – Carla and Donna plus further information on the Symbian Belle update rollout.
Symbian Carla will be released in late 2012 or early 2013 and is intended for smartphones with a 1GHz processor or higher. It will offer a whole new web browser, widgets, NFC capabilities and Dolby Surround audio.

Symbian Donna will be released at the end of 2013 or the early 2014 and is exclusively made for the dual-core processors. We wonder how many cores the mobile processors will offer by then, but now we know Nokia’s Symbian smartphones three years from now will have two cores and Nokia has always been good at optimizing the Symbian OS for far less capable hardware.

The processor minimum requirement means all the Symbian^3 and Symbian Anna handsets (N8, C6-01, C7, E7, E6, X7-00) are not going to get this version
As far as the current Symbian Belle is concerned – Nokia X7-00, E6 and 500 are going to get the update until the end of this year, while the Symbian^3 (already updated to Anna) devices will receive it in Q1 2012. It seems Belle will be the last update for the Symbian^3 and Anna generation.
Nokia is also planning to abandon Symbian in 2016. But the platform has at least four years to live, the new handsets and Symbian versions all have got a warm welcome.

Inside Mandriva Linux

New features

Mandriva 2011 have a host of notable new features. It uses the KDE desktop, but has revamped the UI of most of its components and also added some new tools. Based on experience, Komissarov says that while KDE is a great desktop environment, its broad range of settings may confuse inexperienced users. He cites the example of an experiment wherein a KDE-based distribution was used to teach in Russian schools. The project had to be abandoned because students and teachers were confused by its various settings. Mandriva’s main challenge while designing the new interface was to keep things simple for new users, and expose just the right amount of settings.

Komissarov says the team spent a considerable amount of time investigating the behavior of an average desktop user in a bid to create a distro with virtually no learning curve. It found that users are more productive and prefer running applications in full-screen mode.

Simple Welcome is the main element, which will be developed further- it's not only a program launcher but also a universal container for other original components that are in the pipeline.

TimeFrame - a new utility added to Nepomuk- visualizes files in your home directory based on the time they were created or modified. This saves you the trouble of having to look for files buried deep within multiple folders.

RocketBar implements a software oriented interface that is more convenient and easier for users to understand. Research by Mandriva suggests that a typical user works with an average of about 12 apps. The most used are on the panel and those used less often are stored in the history of Last Used apps, which lets users access the apps in one or two mouse clicks.

StackFolders resembles the stacks feature in Mac OS X and Komissarov believes that users who work with a large number of documents will find this particularly useful. Mandriva 2011's new installer has simplified the installation process by implementing the concept of 'pure choice: While it won't please some advanced users. Komissarov believes that most people are only confused by the many installation options in Linux distro installers.

There have been changes to various other parts of the desktop as well, and many are still under active development. The absence of the option to switch between multiple desktops is just one of the changes to the system tray, which will be further tweaked in upcoming releases.
