WhatsApp to be free for Indian users

IMPORTANT NOTE: Don't extend your Whatsapp  by paying 1$ for indians..This is free for all users in india It automatically extend expiry date by one year and So on.
WhatsApp, the popular Facebook -owned instant messaging service has always been free for a year, and beyond it users need to shell out a nominal $1 a year fee to further use it. However, there could be some good news for Indian users as Neeraj Arora, its VP told the students at the Indian School of Business, Hyderabad that the service will be free for Indian users. A Deccan Chronicle report quoted him claiming that the $1 annual fee will not apply to its users in India.
Reportedly, WhatsApp will not charge Indian users due to the lack of credit and debit card penetration in the country. If it does so, it will risk loosing users in the country. At the moment, the service has 70 million active users, which comprises 1/10th of WhatsApp's total user base.
According to a report by the Hindu Business Line, Arora also believed that Indians could build the next WhatsApp. A former alumnus of IBS Hyderabad he said, " Indians have it in their DNA to build the next WhatsApp for the world."

Learn to develop for Windows Phone 8.1 in one weekend with Channel 9

Preview for Developers
Bob Tabor, Larry Lieberman and Matthias Shapiro are back to teach you all about developing for Windows Phone 8.1. The series is again aimed at beginners and will teach you the basics of things like:
  • Windows Phone UI with XAML layout and events
  • Navigation model
  • Application lifecycle
  • Working with the Windows Phone Emulator
  • Understanding MVVM (Model-View-ViewModel)
  • HTML apps in the WebView
  • Storage
  • Maps
  • Animations
  • Media (Video/Audio with the MediaElement control)
The series will walk you through building five different apps and covers a range of scenarios. You’ll even learn how to make that Windows Phone app a universal Windows app to target Windows 8.1.
Anyone at all interested in developing apps for Windows Phone 8.1 is encouraged to check out the free videos. We’re excited to see a host of new developers on Windows Phone get started through Channel 9 and we can’t wait to see what you build.
Hit up the source link below to check out the series, get the source code and a PDF version of everything!

New technology could allow batteries to last as long as 50 years

Researchers have developed a new battery technology that could help create batteries that last longer than previously thought possible.
A team of researchers at the US Department of Energy's Oak Ridge National Laboratory (ORNL) have challenged a long-held assumption that a battery's three main components - the positive cathode, negative anode and ion-conducting electrolyte - can play only one role each in the device.
The electrolyte in the team's new battery design has dual functions: it serves not only as an ion conductor but also as a cathode supplement.
This cooperative chemistry, enabled by the use of an ORNL-developed solid electrolyte, delivers an extra boost to the battery's capacity and extends the lifespan of the device.
"This bi-functional electrolyte revolutionises the concept of conventional batteries and opens a new avenue for the design of batteries with unprecedented energy density," said ORNL's Chengdu Liang.
The team demonstrated the new concept in a lithium carbon fluoride battery, considered one of the best single-use batteries because of its high energy density, stability and long shelf life.
When ORNL researchers incorporated a solid lithium thiophosphate electrolyte, the battery generated a 26 percent higher capacity than what would be its theoretical maximum if each component acted independently.
The increase, said Liang, is caused by the cooperative interactions between the electrolyte and cathode.
"As the battery discharges, it generates a lithium fluoride salt that further catalyses the electrochemical activity of the electrolyte," Liang said.
"This relationship converts the electrolyte - conventionally an inactive component in capacity - to an active one," he said.
The improvement in capacity could translate into years or even decades of extra life, depending on how the battery is engineered and used.
Longer-lived disposable batteries are in demand for applications such as such as artificial cardiac pacemakers, radiofrequency identification devices, remote keyless system, and sensors, where replacing or recharging a battery is not possible or desirable.
"If you have a pacemaker, you don't want to undergo surgery every 10 years to replace the battery," Liang said.
"What if a battery could last 30 to 50 years? Our fundamental research is opening up that possibility through a new design mechanism," Liang added.
The study is published in the Journal of the American Chemical Society.
