512 bytes, even if the size of the block created by the file system is 4096 bytes, the block calculation here is always 512 bytes. for example, if we write a byte to this file, this file actually occupies the size of a block when a file system is created. The holes in the file are used to save the actual storage space. the holes do not occupy the actual disk blocks. the isize display size contains the hole

I believe many new users who want to learn linux are wondering what linux learning courses are good. The following small series will collect and organize several important tutorials for you to learn, if you want to learn more, go to the wdlinux school to find more tutorials.LinuxMount NTFSPartitioning and attaching MethodsIf your disk is in NTFS format, follow these steps to skip the next step.First download a NTFS-3G: Http://www.tuxera.com/community/ntfs-3g-download/Upload the downloaded packag

, with a good one-way iterative function, you can use the appropriate iterative method to construct the iterative hash function, the hash function of the security design theory has the following two points: one is the one-way function, and the other is the randomness of function mapping. The common hash algorithm is MD-5, SHA and so on.Introduction to the 2.SHA1 algorithmSHA (Security hash algorithm) is a standard hash algorithm for the NIST and NSA designs in the United States, originally publi

In the case of KVM or Xen virtualization, it is often necessary to use the mirror files (image file), we can start the guest system, and then modify the mirrored file, but this is sometimes more cumbersome, in fact, can be the image file directly mount, There are two ways to do this.method One: Find the starting position of the partition, and use the offset parameter of the Mount command to offset the unwanted before you can get the real partition. the specific steps are as follows:1. Use "Fdisk

1. Start live cd with a cd for Ubuntu installation. (If you were using a USB flash drive, you can use a USB flash drive instead of live cd. The effect is the same. I use thinkpad, press F12 at startup, select start from usb, and enter the linux system by default.) 2. Open the terminal and enter the command ubuntu @ ubuntu :~ $ Sudo-I # Switch to the root user identity root @ ubuntu :~ # Fdisk-l # view the partition of the computer disk.
