World of Warcraft: always a Metro in advance!

It is say stalled, WoW is still the Rolls of the MMO in terms of playing comfort, and proves it with this new feature: automatic rollback of object.

The principle is simple: If an unfortunate handling made you swing your favorite axe to nettles (recall that play after a night watered, it is wrong), now simply a simple visit to your Battle.net account to repair the error. In fact, it should be noted that this option existed, but that it required to go through the standard procedure for technical support, which could take 2-3 days.

This time, the operation is almost instant, and the lost object is found in your mailbox in under a minute. A system that just add to the long list of tips to simplify life, that it would like to see across so it is practical, and that there is finally as Blizzard. By contrast, BioWare should integrate the transfer of characters between servers on its Star Wars: The Old Republic by the summer. Hum...

The smallest MP3 player in the world?

Up to 32 GB of music in a small "Kube"...

This Kube2 is presented as being the smallest of the world MP3 player! Nothing than this. Let us to doubt, because it still has the impression that the iPod Shuffle 3 G is less bulky. But well, let's. It has the advantage to accept a micro-SD card allowing to offer up to 32 GB of storage, and to be customizable via various stickers to stick on its aluminum coating. This MP3 player offers 6 hours of autonomy on a battery that recharges completely in 1 hour on USB port.

The Kube2 is launched at a price of $ 35, but is only available to Singapore for the moment. Rest following a presentation scheduled in the next, it should be marketed around the world. However, it remains quite secptiques the interest of a "square" format, not necessarily very pleasant to fit in a pocket. Also remains to be seen if it pilot only via a wired remote control buttons or if it has buttons hidden somewhere on one of its faces. Because the absence of controls on the iPod Shuffle previously cited signed his judgment of death as early as its launch, allowing change of listeners without to go through expensive adapters that uncomfortable or unsightly.

Sharp has the smallest sensor in the world

Small technological feat to Sharp which presents the smallest photo sensor never designed, but still 12.1 Megapixels!

Smartphones and tablets include sensors photo still more small but whose resolution only increases. As such, the nippon Sharp has a new cap in the miniaturization of these sensors. It is, according to the manufacturer, the smaller sensor ever developed to date.

1/3.2 CMOS format, it is only 11 x 11 x 5.47 mm. What does prevent him from boarding an image stabilizer, a backlight module to improve the quality of the photographs (including in low light conditions), and to propose a resolution of 12.1 Megapixels.

A technical feat, especially this sensor is capable of filming in HD 1080p. Quite logically, they are first Sharp products that integrate this sensor, including the Aquos SH - 01 d and 102SH who must exit at the Japan before the end of the year. But after, this small sensor photo/video will be produced in mass and there are chances that found integrated with products sold in us.

K, the most powerful computer in the world

Small victory for the Japan: the land of the rising sun took over first place in the ranking of supercomputers to China. Built by Fujitsu for the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, K Computer offers a computing power of 8 petaflop (8 million billion operations per second floating-point), 3 times higher than that of Tianhe 1 - Chinese A, the previous world champion.

The measured power is very close to the theoretical power of K Computer (8.77 PFlops) which is unusual for a supercomputer. Unlike a recent trend, K Computer does not appeal to hearts GPU to accelerate treatment and is based entirely on a CPU. Fujitsu has used its home, the SPARC64 VIIIfx with eight hearts processor and running at 2 GHz. 68 544 processors form K Computer, for a total of 548 352 hearts. The monster requires 9.9 MW of electrical power, a new record also. Here its commissioning official in 2012, K should still grow (80,000 CPU) to exceed the symbolic cap of 10 PFlops.

Supercomputers crossed another cap as the top 10 in the world exceed all the petaflop. The France class in ninth position with the Tera 100 built by Bull for the CEA, which offers 1.05 PFlops, consumes 4.6 MW.
