Now the hard drive is getting bigger, and the original MBR partition, more than 2T hard drive will not be recognized, only use GPT way, but GPT if the original BIOS is unable to boot system, but if your motherboard support EFI, then you can use the Gpt+efi way, Support 3T large hard drive installation system.

Today I see someone is already discussing how to get Google satellite images, see http://www.cnblogs.com/tangf/archive/2006/07/23/457902.html? Login=1commentid=1507040#post a blog, which copied the JavaScript and Delphi code to come, I am here again to copy again lest everyone look for.
The algorithm thought as follows: Google satellite image server, by different levels of 256x256 JPEG image seamless stitching, the encoding is based on the Qrst encoding method index:

slower than FC disk.Why we prefer FC, SAS, and SCSI is because the server's hard drive does not consume the main CPU time when it transmits data.At this point they are essentially different places.So choose the server, do not choose SATA hard disk, to choose SCSI.2)There is also a very strange place about capacity.SATA disk capacity has reached the T level, there is a T, two T,Teacher Lecture Time is 2012, now is 2016, 2T has been very common, 3T dis

MongoDB Engine: MONGODB 3.0 supports user-defined storage engines, which users can configure using the Mmapv1 or Wiredtiger storage engine.

problemFor the multiplication of two large integers, for example, the number of two digits is 1024x768, and the C language cannot represent such a large number. But we can use the Division method to find their product.SolveWithout losing its generality, two numbers a and B are n bits, and n is the power of 2. If this condition is not met, you can make them satisfy by filling the 0 operation.A:
A1
A2
B:
B1

decoding the next command. This is the classic three-level pipeline, as shown in 3-1.
As shown in Figure 3-1, it takes 5 TB to execute three commands on the third-level assembly line, and 9 TB to execute the commands without using the assembly line. The third-level assembly line is used in the arm7. However, nothing in the world is so simple and perfect. It is assumed that the time required for obtaining, decoding, and execution is T. Actually, this is not the case. For example, it may take a
