Nokia Lumia 920 vs. Lumia 900

Just five months after grandly returning to the United States with the Lumia 900, Nokia’s switching it out for an even better Windows Phone 8 offering. The 920’s coming with a beefier display, better internals and has wholly embraced wireless charging — but that’s not the feature everyone’s gonna be talking about. No, that’s reserved for the 8-megapixel PureView hardware and the new imaging tech behind it. Still, that shouldn’t distract from the real business at hand: identifying the tiny hardware differences that separate the current and future iterations of the flagship, which we’ve broken down for you after the break.

Sony is arrived with the new smartphone without green logo. Sony Xperia series has added a new member, as the Sony Xperia J. Sony Xperia J is code named ST26, and the phone has been dropped on the web recently.
On that occasion I learned that the new smartphone running on Android 4.0.4 and support a resolution of 854 x 480 pixels. The image right side would be new phone, according to Asian website IT168. Interestingly, I see no trace of specific green logo Sony / Sony Ericsson, who was present on all models so far.

Rounding up the lower end of the segment is the newly launched Sony Xperia J. The 9.2mm thick phone has a FWGA display. A 5MP camera unit can be found around the back of the phone.

The Xperia J comes with a front facing camera to allow video calls. Details are still coming in but the phone will be available in black, gold , white and pink when it is available towards the end of the year.
Price for this phone is not yet confirmed.

Sony Xperia J Specifications:

The Sony Xperia J offers a great screen for its price range – a 4 Inches screen of FWVGA resolution and Gorilla glass. The phone itself is powered by a single-core 1GHz Scorpion processor with 512MB RAM and will launch with Android ICS, just like its more expensive siblings. It has 4GB of built-in storage plus what you put in the microSD card slot.

Scientists achieve 186Gbps transfer rate across standard fiber optic line

Heralding a practical new way to transfer data at unprecedented speeds, scientists from Caltech and the University of Victoria have achieved a sustained data transfer rate between computers of 186Gbps, across a standard, commercially available fibre optic line. Real world applications for such speeds already exist, with many scientific projects across the world needing to share petabytes of data with other institutions.

The team of researchers consisted of scientists from various fields, including high-energy physics, computer science, and engineering. The 186Gbps transfer rate (98Gbps in one direction, 88Gbps in the other) was achieved over a 100Gbps bidirectional fibre optic line that stretched 217km from the SuperComputing 2011 (SC11) convention in Seattle, to the University of Victoria Computer Centre in Canada.

While speeds of more than a 100Tbps have been achieved in the past, they have either been inordinately expensive, or done over specialized networks. Also, the team from Caltech and the University of Victoria transferred data from computer to computer, quite different from just a demonstration of speed


The Caltech team at SC11 used 13 servers and 40Gbps LAN connections, while University of Victoria team used 10 servers and 10Gbps LAN connections to achieve the two computer-to-computer data transfer rate records, which were sustained for 11 hours each.

The first record, the 186Gbps data transfer rate (~23.25GBps) was achieved in a memory-to-memory transfer, while the second, 60Gbps (~7.5GBps) was achieved in a disk-to-disk transfer.

Refer to the Caltech SuperComputing 2011 site for more details about the equipment used in the record-breaking attempt, as well as the Caltech press release. Also, check out the rather excitedly narrated video below, demonstrating the team’s efforts:
