WebOS Community Edition of output: it is party to the change of TouchPad

HP has making available the source code of the Community Edition of WebOS for TouchPad.

It is through his blog dedicated to developers that HP released new components on the WebOS Open source system. A version called Community Edition which must offer the TouchPad Tablet owners the opportunity to continue to see their operating system evolve through volunteers of developers to the world of free software.

We learn therefore, after Open-source of various elements, the WebOS Community Edition source code is now available for download. Attention, do not confuse the - dedicated to the HP - Open WebOS Tablet whose first final version should be available in September (see article). Indeed, Open WebOS for its part aims to provide a free system derived from WebOS is compatible with other tablets.

"The availability of WebOS Community Edition will allow you to learn as the TouchPad Tablet works and modify according to your preferences." All these knowledge you will be of course useful Open WebOS 1.0 "ensures the team in charge of these projects at HP. All necessary information are available here, while the WebOS Community Edition source code can be found here.

The GeForce GTX 580 that dust and change color

MSI released a new GeForce GTX 580 overclockée, hunting the dust and changing color temperature of the GPU…

The N580GTX Twin Frozr III 15D5 Power Edition/OC (thank you guys from marketing...) is - as its name suggests - overclockée and equipped with a cooling House the "Twin Frozer III" system offering two original innovations.

The map based on GPU GeForce GTX 580 is therefore on-fréquencée factory to 810 MHz for the GPU, 1620 MHz for shaders and 4008 MHz to 1.5 GB of GDDR5 (against 772, 1544 and 4008 MHz for the GTX 580 reference), not what jump to the ceiling.

Is cooling system, provided by a wide radiator crossed several heat pipes copper aluminum all surmounted by two fans of 90 mm which have the particularity of change of colors, from blue to white, when the GPU exceeds the 45 degrees Celsius. "Dust Removal Technology" system fan blades clearing even the dust by turning in the opposite direction for 30 seconds during startup of the machine, thus propelling the flow of air upward instead aspire to the bottom.

Map measures 30.5 cm in length, it occupies two slots, proposes two in Dual Link DVI ports, an HDMI, and a Displayport and consumes according the 260 Watts constructor. It will be available on the French territory the week next to a tariff of €559 with a coupon giving right to the Battlefield 3 game download on the Origin of EA platform.

Here's a video of presentation of the card and its system of cooling operation.

Linux is passed in 3.0, a minor change

The Open Source Linux kernel is 3.0 without the modifications of a major version.

The launch of version 3.0 of the Linux kernel, Linus Torvalds, still active around its Kernel Open Source, announced this weekend. According to him, is that an update of routine and should not be expected, despite the numbering of this version, to radical changes. The developer said to be simply tired of the ramifications of the numbering in 2.6, the latest was version 2.6.39 released in May.

"What are the major new features?" No. There is nothing. We have some usual changes on the drivers and fixes. "Nothing to do with KDE 4 or Gnome 3 with the new kernel" had already warned Linus Torvalds some weeks ago. Perhaps this is the anniversary of Linux, which will celebrate its 20 years, which pushed its creator to decide the transition to the 3.0.

At the level of the changes, it notes, however, changes to the caching of pages and the revision of Btrfs file system integrated since the 2.6.29. Automatic defragmentation tool found and a compiler on the fly for GMP packets. Everything is explained in French on LinuxFR.org.

Is it time to change your PC?

"My configuration still takes the road."

Typically this is the kind of question is fairly regularly when it is demanding or chronically to the approach of the holidays of end of year/anniversaries. Many of us so rushed on an Athlon 64 or Athlon 64 X 2 during the last decade of the fact of their very good performance in a globally accessible pricing.Intel signed his return to large pumps mid-2006 with the Core 2 which had better performance and better performance to offer AMD. Configurations using these processors are still very many at the present time. But how they behave from the bullets of today? We opposed platforms LGA 775 and LGA 1156 to respond.

Extent to which has progress been substantial?

For some time, CPU are gradually gaining in performance and functionality while remaining in the same thermal envelope (between 65 W and 130 W). In 5 years, the number of hearts is quietly passed from one to six (and even 12 in the AMD Opteron). The frequency on the other hand, fell (Intel found only on the latest Core i7 level D and Pentium 4), despite the progress of the fineness of engraving: 65, then 45 and now 32 nm. Intel was able to more quickly ensure these transitions, which allowed him to improve the density of transistors and thus to be more generous with the cache that AMD.Similar transitions were made at the level of graphics cards: If most have only a single GPU, all are massively parallel architectures. The increase in the performance of the GPU is directly linked one execution contained in each bullet hearts. In addition, as NVIDIA ATI have developed modes multi GPU with two, three or even four cards by configuration. There is also that graphics cards have also found usefulness outside the games via ATI Stream and NVIDIA CUDA and OpenCL programming tools. In 5 years, the maximum consumption of cards while doubled or tripled (a Radeon X 1800 XT had a 81 W TDP, a Geforce GTX 480 requires 250 W), but clearly, the performance per Watt exploded.The DDR3 is now the memory the most sold type. If the frequencies have not ceased to increase, the DDR3-1333 is suitable for most of us. This being, having 4 GB or more became imperative with some programs coupled with a 64-bit Os. Those who can have replaced their drive system hard DSS, which are more quiet, high-performance i/o and display a low consumption. With operations in reading, SSDS are untouchable but cannot say the same in writing where there is good and less good. Is the cost per gigabyte that still is a real drag.

Let us not forget the motherboards: SATA 3 Gb/s came in 2007 with the NCQ, high range models are often entitled to Advanced RAID features, USB 2.0 ports have multiplied while the eSATA is sometimes required. HD audio chips, gigabit Ethernet and PCI Express ports are remained constants, although the PCI Express 2.0 has started to become widespread with the advent of the Intel P45 chipset. The current motherboards embark on economy of energy and overclocking functions advanced while USB 3.0 and SATA 6 Gb/s start to become common.

Google and Facebook should change servers

Google and Facebook should proceed with an update of their servers at the end of the year which will coincide with the release of the Interlagos of AMD and the Romley, the new Sandy Bridge for Intel Server using a Socket LGA 2011. According to DigiTimes, who allegedly received information from manufacturers of servers, this should create a wave of renewal of machines and related products, such as storage or network devices.

Romley will integrate eight cores taking processors support Hyper-Threading and motherboards dual for a maximum of 32 threads. Companies are now restored the economic crisis according to assemblers, which are cited by DigiTimes. Their new economic health explains this desire to update their infrastructure.

Intel showed the first Romley to the IDF in September 2010. They integrate a memory controller channel compatible DDR3 LRDIMM (Load Reduced Dual-Inline Memory Modules) that allows systems using more than 32 GB of memory to turn each bar to its maximum rate. Conventional controllers are unable to maintain the integrity of the data of this type of configuration because of a deterioration of the signal that occurs when using all chip memory. With the LRDIMM, Intel can support 96 GB without loss of frequency.

The LRDIMM uses a buffer which reduces the flow of information between the processor and memory. The bus is therefore less taxed by the increase in the memory modules. The LRDIMM is a derivative of the MetaRAM technology. It allows to virtually consolidate a series of memory chips to simplify the task of the controller and increase the capacity of the bar. For example, it is possible to place 32 125 MB modules for a bar of 4 GB and the system sees that 500 MB 8 chips. It can be more modules on a bar. The problem is that the buffer required for the proper functioning of this technology is expensive, which explains that the LRDIMM are before any reserved for servers.

Rumours that circulated last month the Sandy Bridge Romley will use memory cache L3 2.5 MB per core, for a total of 20 MB, and will have a TDP which will be included between 40 W and 95 W following the requests of the system. They will be coupled with the chipset Intel Patsburg-B. The Romley should be marketed under the name of Xeon E5. They will also have two links QPI, 40 rows PCI-Express 3.0, 4 DMI 2.0.

They will be opposed to the Interlagos of AMD will be built on the Bulldozer architecture. They integrate between twelve and sixteen cores, memory four channels and 16 MB of L3 cache controller. They should be marketed at the same time as the Romley.
