Technology firms to spend $150bn on building new data centres
Google in recent results showed that $ 1.6 billion invested in the construction of data centers only during the three months from April to June
When Google filed its Form S-1 in April 2004, prior to its IPO, it became clear that not only it was already very profitable - to $ 105 million (67 million pounds ) on sales of $ 1 billion in 2003 - but has also invested hundreds of millions of dollars to build a network of servers around the world.
spectators quickly realized that there were hundreds of thousands of servers - and Google itself has made parts. It was at that time the manufacturer of the third servers in the United States. But he has not sold one.
The cost of building a "cloud service" as Google has only increased: in its latest results revealed that 1.6 billion invested in data centers in the three months to April-June This has now become typical Google spending - $ 4 billion per year -. The systems used to index the web, answer questions, advertising, manage email, photographs store and provide maps and Street View photos
not alone: ??Google, Facebook, U.S. phone company AT & T services company Wipro also has centers there, attracted by the cheap electricity and plenty of space in the rural state, center can cover the space and use as much electricity as a small town. They are hungry for power and volume data. Servers needed to process the data must be placed in lockers forced air cooling on them, storage is arranged in racks of hard drives that are configured in the hope that some course, but to be replaced. The information enters and leaves the optical fiber with thick cables routed through the floor.
However, the construction of data centers is increasingly a struggle between access to space, and the connection speed. Before the 2012 Olympics, some IT managers in financial centers of Canary Wharf in East London, with frets would not be able to get enough electricity to power its new centers - which would be located near Floor box nonstop commercial valuable precious milliseconds time trading. Some briefly considered moving outside London - but changed his mind and now have additional energy sources in place to deal with them

USB cable leave behind
I want a better way to transfer photos from the phone to the computer. At this point, I can connect my camera to the computer via USB and use the "drag and drop" function. I know you can also use AirDroid on my phone to transfer files over Wi-Fi. The third option is to use the instantaneous load Dropbox to transfer the file (size, best quality) with my Dropbox account. Then downloads to your PC automatically via Dropbox.
send files via Dropbox optimal?
AirDroid Dropbox and methods are incredibly comfortable and I find myself wanting to leave behind the hassle of connecting via USB. I refuse to change the way, though, because I do not want errors or erosion of data quality. The research I did a few years ago gave me the impression that data errors can occur when a file is sent wirelessly. Is there a reasonable risk of data loss using AirDroid or Dropbox, or technology has advanced enough that you can safely leave behind the USB cable?
Tiefenbach Dan
The doctor answers:
any transmission technology has the potential for errors in the data, but that's why all the techniques of data include the correction of errors. Since USB 3.0 Wi-Fi for the TCP / IP protocol, the data correction algorithms are there to prevent errors creep into their data. The doctor never had a damaged or deformed when wireless digital file.
can see for yourself if you want. Take a picture of your phone and copy it to your computer via USB. Send a copy to yourself from the phone and load another copy via Dropbox. They all end up exactly the same. You can test this by using a free tool for comparing files at the bit level.
The doctor took a photo taken last week with a camera phone and email. The file was from the phone via the Verizon network via the Internet with the Exchange server work through RAM PC LAN work, then CPU, hard disk. The same image sent by Dropbox, from the phone through Verizon's network through the Internet to servers on the local network to work Dropbox and so on for the PC. It's a long hop to any file via the mobile operator's network data, not just the Internet. Both WinMerge (free www.winmerge.org) and comparing MD5 Tool files (http://bit.ly/jKhpjR) agreed that the files are identical, little by little.
You should see absolutely no difference between the two files if everything is working properly. If you look at the differences between files, is probably due to a corruption issue equipment, but a problem of this kind are likely to produce errors when running the operating system, too. If you can not read or copy a single image or a Word file, you will probably cough also opens a binary file hairballs. The doctor would not worry about data corruption, but if you move a lot of files, USB is almost always faster. We say "almost" because some cameras / phones through USB transfer speeds pretty atrocious.
In general, however, unless you transfer a lot of things at once, it is normal to leave the USB cable at home.
PCIe x8 SLI
I recently built a video editing / PC games on the Asus P8Z77-V PRO. This is a great piece of hardware, but it's only dual x8 SLI mode. When I install another GTX 670 next to my current and connect the SLI bridge, I see performance worthy to spend another $ 300? How do they compare with SLI in x16 mode?
Alex Dalton
The doctor answers:
should see almost twice the performance of a single GTX 670 when you have two in SLI, regardless of whether they are at x16 or x8 mode. You will not see a slowdown despite mode x8, x8 PCIe 3.0 is more than enough for a maximum of two 670S.
HDMI DisplayPort
In?
I've seen discussions on connecting an output of the DisplayPort graphics card to the HDMI input port on a video screen. Cables and adapters are available to make the physical connection. However, I wonder if the rules of DisplayPort and HDMI ports allow a proper connection HDMI output port on the graphics card with DisplayPort input to a video screen. The physical connection is possible, by all appearances, but works fine?
- Dennis folder
The doctor answers:
Nan. You can switch to DP HDMI (or DVI or VGA), but does not work in reverse. According to the FAQ DisplayPort (www.displayport.org / faq) to switch to DP HDMI in. However "no cost-effective way," it is likely that the HDMI output is not a single GPU, or one DisplayPort input your monitor. If your monitor has a DVI input, just use the DVI connector on the GPU. If your video card has a DVI output, and it is really only HDMI, use a HDMI-DVI cable, you can get one on Amazon for seven dollars. You miss out on HDMI audio, but at least you have a picture.
Updating an old case
I have an aluminum Lian Li PC-62 was old serves me well for a number of years. I updated the internal hardware a couple of times over the years, and update soon. The case is equipped with USB 2.0 ports on the front. If I upgrade to a new motherboard with USB 3.0, I'd be able to get USB 3.0 ports I / O panel. How is different from USB 3.0 to USB 2.0? Is it just a matter of connecting the port to the right header on the motherboard, or I need to replace the entire port? Do they even sell spare ports for this issue, or should I go with an accessory to go with a 5.25 or 3.5 inch disk replacement?
- Bob Berno
The doctor answers:
USB 3.0 internal connector is very different from the USB 2.0 header, and is not compatible with the previous ports. The header USB 3.0 has about twice the pins. The Lian Li site has a page that shows the packages update for your USB 3.0 (www.lian-li.com/v2/cable/cable.html) models, but it seems that the PC-62 is a them.
