Developments in the Intel x86 with AVX2

After MMX, SSE (2, 3, 4, etc..) And AVX, AVX2 here. This extension of the x86 instruction set will be given on the next generation of processors, Ivy Bridge. In New features include a "homecoming" of SIMD - single instruction multiple data may change - can work on integers is 256 bits. Back to basics, because the first set of SIMD instructions on x86 was the MMX, which allowed just this type of manipulation, while the following were focused primarily on floating point data.

TDJ: AData and USB 3.0, Corsair 600T White

The AC700, the Acer Chromebook repulsed

The AC700, the Chromebook Acer, would be delayed to an unknown date, while in pre-order since June 15 and was due June 24 A blow to the operating system from Google: the only machine that should be moved to the launch is a Samsung model. Recall that Chromebook use the operating system from Google, Chrome OS, and the machine is dedicated to the cloud.

Specifically, the capacity of local storage is very low (16 GB) and the machine is dependent on an internet connection. One problem with the model of Acer is the price: $ 380 AC700 is proposed in the U.S. with features very (too) classics for the price: 11 inch screen 1366 x 768, Atom N570 (dual core) , 2 GB of RAM and 16 GB SSD.

Lifespan of SSD: Epilogue and Future (10)

On 20 December, we launched an interesting experiment: try to use a DSS to see if life really was a problem. For those who do not follow our adventures, we used a model based on MLC flash memory and 4x nm driven by a Barefoot home Indilinx. The SSD in question has survived for 4 months while we were writing continuously from a Velociraptor.

In total, we wrote about 650 terabytes of data before the SSD begins to cause problems with errors in the proofreading of written data. Ideally, we wrote between 500 and 1000 times more per day than what SSD manufacturers use it as a classic: the values announced vary from 5 to 10 GB for an average user and we were around 5 TB Two problems arose: first, sequential writes use less than the SSD random writes of small files (current standard in use), because of the very structure of flash memory, and secondly we realized that the updated firmware - in some cases - resetting the information on the wear of the SSD.

Dropbox encrypts the data but keeps the key

Dropbox, a cloud storage service very popular, is the center of a controversy: the data, advertised as 256-bit AES encrypted, are available to company employees. Indeed, the company has a copy of the encryption key for one simple reason: it needs to limit the costs of storage service. Explain. Start from a specific point: the storage has a cost.

And therefore, the amount of data stored has an impact on the company's accounts. To try to limit these costs, Dropbox integrates management of duplicate files at the server level: a file is physically present only once on Dropbox, even if multiple users send. The interest is double-side Dropbox: firstly, it is stored pressed once (and not five, ten, a hundred times) and secondly there is a gain bandwidth, since the sending a file is already present snapshot, regardless of its actual size.

Mushkin holy feast Secure Digital
