Free Wi-Fi for facebook users soon

WASHINGTON: Facebook users; rejoice! Your days of repeatedly asking for Wi-Fi passwords at coffee shops may soon be over.
The social networking website is testing a new Wi-Fi hot spot service for local business that grants users free Internet access if they do a Facebook check-in.
Businesses would provide the access via a Facebook router that directs customers to its Facebook page once users check in,the 'discovery news' reported.

MacBook Pro - Review

The new MacBook Pro with Retina Display was the big reveal at Apple's WWDCkeynote. Bringing the iPhone 4S and the new iPad 3's much-vaunted killer feature – their nonsensically high-definition screen -– to the Cupertino crew's notebook line, rather than the iMac desktops as many had suspected, it stood alone as an all-new product alongside refreshes of the MacBook Air and standard MacBook Pro lines.





Yet with ultrabooks such as the Asus Zenbook and HP Envy 14 Spectrebuilding on the success of the Apple MacBook Air, bringing compact power and flexibility to the affordable end of laptops, is a super-charged, super-priced portable chock full of the latest technological advancements aimed at professionals rather than hardcore gamers cumbersome and unnecessary?

To find out, we tested the entry-level £1,799, 2.3GHz version of the Apple MacBook Pro 2012 with 256GB hard drive, although there's also a 2.6GHz version of the Mac Book Pro with Retina Display with 512GB hard drive for £2,299, with greater custom specification also available.





Features

We'll talk about the screen later, but that's not all the new MacBook Pro has going on. First of all, it has wired and wireless connectivity down, from SDXC card support to 802.11n Wi-Fi and Bluetooth 4.0. The two speedy new USB 3 ports – one on each side as ever, handily – are also backwards compatible to USB 2, while two Thunderbolt ports, headphone jack and a single HDMI out complete the set.
To be honest, beyond a display, we still struggle to find things to put in our Thunderbolt holes and would have preferred it to fly solo, with a third USB taking its place. Yet the lack of FireWire or Ethernet access means you may be thankful for them as these can both be connected via Apple's Thunderbolt adaptors.
The new and improved 720p HD front-facing camera does a fine FaceTime/Skype job, but ironically its images and video look a bit washed out and degraded on the Retina Display's sharp screen.
AirPlay mirroring is responsive and reliable, and while our MacBook Pro packed the Retina-optimised Lion operating system, the upcoming Mountain lion OS is primed to raise the feature bar even further from July.
Yet what won’t be coming is an optical drive, which has been reduced, MacBook Air-style, to an external add-on. For something as purposefully entry-level as the Air, this seemed understandable, but on a professional notebook it will not be a view everyone shares.

How would it be if you can charge your mobile Wireless….?



Of course, Intel is trying it and if it works then Alternate current or Direct current transmitter will be placed on all the walls and you can charge your electronic gadgets just from there without any wires and without any contacts. Yuppie that’s Intel call it as Wireless resonant energy link and it can send a 10 MHZ to a feet of distance. The idea for wireless power transmission was first suggested by Nicola Tesla. Science fiction writers eagerly seized on the idea in the early twentieth century. In The Mightiest Machine, a novel serialized in Astounding Science-Fiction in 1934, the technology makes an appearance. Alanson Sample, an Intel Research Seattle intern, shows the apparatus of a Massachusetts Institute of Technology idea called wireless resonant energy link (WREL) that can transmit power with no wires and without so much of the loss of energy that afflicts other wireless power transmission technologies such as induction.

The technology can transmit 60 watts of power to illuminate a light bulb and it has 75 percent efficiency they say. wonder how would you charge your laptops now ? ;)
