Nokia Lumia 900 Launched in India @ Rs. 32999
Yes!, Finally the awaited lumia 900 phone is now available in India via Nokia.co.in and Flipkart.com at a price tag of Rs.32,999.
Lumia 900 features a 4.3 inch Super AMOLED screen, on a 1.4Ghz Scorpion Single Core Processor with 512mb RAM, running Windows Phone 7.8. The Indian version of Lumia 900 also has support for LTE (4G) cat3 @50 Mbps.
The Phone boasts a 1830mAh battery which promises 7Hrs of Talktime and 300Hrs of Standby on both 2G and 3G.
Other features include, 16gb inbuilt storage which is not expandable, since it has no SD-card support. an 8mp Auto focus Camera with dual LED Flash. and a secondary front facing camera of 1mp for video chat.
The Nokia Lumia 900 will not get Windows phone 8 Update as recommended by Nokia. Since Other Nokia Lumia 610, 710, 800 are also running Windows 7.5 with similar specs, I think its too late for Nokia to sell this phone in India.
At the Price of 33,000 there are much better alternatives to this phone, featuring Full HD, 3D Playback support and Dual-Core Processing and with expandable memory of about 32GB.

PowerLine Networking

What Is A Powerline Network?
Your home already has a network of wires in it that connect every room in the house. These are the wires that provide each room with electricity. Normally, these wires are used for only that task, but it is possible to turn them into a way of conveying data like any other wire.
>> This is exactly what a powerline network does. Power line Networking can be used in a home to interconnect home computers and peripherals, and home entertainment devices that have an Ethernet port.
>> The Powerline adapter sets plug into power outlets and establish an Ethernet connection using the existing electrical wiring in the home. (Power strips with filtering may absorb the power line signal).
>> This allows devices to share video and data without the inconvenience of running dedicated network cables.
>> Doing this has no effect on the normal function of the electrical wires, either – all your power outlets will continue to work normally
Advantages of a PowerLine networking:
>> It's inexpensive.
>> It uses existing electrical wiring.
>> Every room of a typical house has several electrical outlets.
>> It's easy to install.
>> A printer, or any other device that doesn't need to be directly connected to a computer.
>> Sniffing can be avoided to some extent in a dedicated link.

NFC(Near Field Communication)
NFC standards cover communications protocols and data exchange formats, and are based on existing radio-frequency identification (RFID) standards including ISO/IEC 14443 and FeliCa. The standards include ISO/IEC 18092 and those defined by the NFC Forum, which was founded in 2004 by Nokia, Philips and Sony, and now has more than 160 members. The Forum also promotes NFC and certifies device compliance.
NFC builds upon Radio-frequency identification (RFID) systems by allowing two-way communication between endpoints, where earlier systems such as contact-less smart cards were one-way only. Since un-powered NFC "tags" can also be read by NFC devices, it is also capable of replacing earlier one-way applications.
Bluetooth and WiFi connections
NFC offers a low-speed connection with extremely simple setup, and could be used to bootstrap more capable wireless connections. It could, for example, replace the pairing step of establishing Bluetooth connections or the configuration of Wi-Fi networks.
Social Networking
NFC can be used in social networking situations, such as sharing contacts, photos, videos or files and entering multiplayer mobile games.
Gadgets which support NFC Technology
BlackBerry Bold 9790, 9900, 9930, 9350,9360, 9370, 9380
Google Nexus S, Q, 7
HTC Incredible
HTC One X
LG Optimus Elite
LG Optimus L5, L7
Motorola Droid Razr

Microsoft creates a one trillion pixel, 802 GB image of the night sky
Look at the picture above. It is a toned-down, 500x500 pixel version of an iconic picture. Had we had the audacity (or the facility!) to put up the full blown picture that this actually is, it would have taken you a couple of years to load this page on your normal broadband connection. One terapixels, yes, 1,000,000,000,000 pixels displaying the sky in all its glory and taking up a whopping 802 GB of disk space.
A gigantic effort (literally!) by Microsoft, this picture of the night sky is the largest and the clearest ever. Under the Terapixel project, 1791 pairs of complementary red-blue captures were stitched, thanks to image data from telescopes in California and Australia collected under the Digitized Sky Survey during the past 50 years.
To know the extent of the huge-ness of this picture, gulp this - To view it in all its glory (read pixels), you would need 500,000 High Definition TVs in a grid. Even if you take the higher-DPI route of printing, the photo would be the size of a soccer field.
According to Microsoft, this is the recipe behind the Terapixel photo:
1.> Image data was computed, or digitized, from the plates that were created directly from the telescopes. This raw data was processed by a computer cluster using 512 computer cores (How many does your ‘ultimate gaming-rig’ use? 4 huh?). According to Microsoft, this took about half-a-day. Sounds deflated, if you ask us.
2.> The red and blue complementary pictures were then combined and the pictures were then touched up to correct the variations in brightness, colour saturation, noise and vignetting (darkening of corners). Three hours. Impressive again. We bet those computers weren't running Vista.
3.> It took four hours then as the images were converted into the seamless panorama of beautiful stars.

Four Ways with IPv6 Will Save the Internet
The world is almost out of IP addresses--or at least it's almost out of the IPv4 addresses that IT admins and users are most familiar with. Fortunately, IPv6 has been developed to exponentially expand the pool of available IP addresses while also providing a few other benefits.
To address issues with the current IP protocol in use (IPv4), and to add features to improve the protocol for the future, the Internet Engineering Task Force (IETF) has introduced IPv6 (Internet Protocol version 6). Let's look at a few ways that IPv6 will come to the rescue and save the Internet.
1. More Addresses: IPv6 uses 128-bit addresses rather than the current 32-bit addresses allowing for an exponential increase in the number of available IP addresses. Network routing experts have been aware of the limitations of IPv4 addressing since the 1980's--before most of the world even knew the Internet existed, and before the Web became ubiquitous.
With 32-bits, IPv4 only allows for approximately 4.3 billion IP addresses. Since every Web-connected device--server, desktop, notebook, smartphone, tablet PC, and more--must have an IP address, and since the Web has exploded in countries like China and India, the world is rapidly approaching the end of the available IPv4 addresses.
2. Backwards Compatible: IPv6 is backwards compatible with IPv4 so that different networks or hardware manufacturers can choose to upgrade at different times without disrupting the current flow of data on the Internet. Given the world's dependence on the Internet and Web for news, commerce, public safety, national security, and more this is an important feature of IPv6.
Eventually, all IPv4 equipment will be replaced by attrition and IPv6 will be the only address protocol in use. But, that could take decades, so backwards compatibility will be crucial for the foreseeable future.
3. Better Security: IPv6 was designed with encryption and authentication in mind. IPsec is an optional security component of IPv4, but in IPv6 it is mandatory. With IPsec each individual data packet is encrypted and authenticated, making many of the malicious attacks plaguing the Internet today impossible--or at least substantially more difficult.
4. Better Performance: Changes have been made to the way IP packets and headers are formed, and to the way IPv6 routers process the packets to improve performance--resulting in fewer missed or dropped packets, and more reliable and efficient connections. With more people and devices sharing the Internet, and higher demands for VoIP (voice over IP) and video streaming, performance will be more critical than ever.
