is tty. It also sets a special device file name: % K. In this example, % k indicates the kernel name of the device. This means that the kernel identifies the names of these devices and creates the file names.* The KERNEL = "scd [0-9] *" starting from line 3 indicates the SCSI CD-ROM driver. It creates a pair of device symbolic connections: cdrom and cdrom-% k.* In the fourth line, the starting KERNEL = "hd [a-z]" indicates the ata cdrom Drive. This r

How to view the hard drive brand model and other details, CentOS brand model First, use the smartctl -- all/dev/sda command to check the hard disk information. This command comes with CentOS. The result may be as follows: Smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-358.el6.x86_64] (local build)Copyright (C) 2002-12 by Bruce Allen, http://smartmontools.sourceforge.net=== Start of information section ====Device Model: WDC WD20EZRX-00DC0B0Serial Number: WD-WMC301111333Lu wwn Device Id: 5 00

) function calls init/main. the init () function in c will create two new kernel threads, dbflush and kswapd, in the init () function. Initialize the tty1 device. Find/etc/init or/sbin/init or/bin/init to create an init process. The Init process checks the file system according to the/etc/inittab file, starts the system daemon process, establishes the getty process for the online terminal, and executes the command file under/etc/rc. After that, getty will display a login prompt on the terminal t

size of the sample n=0, then we think s2=x=0. For example, we want to count the DNA sequence ' atatata ':1. For the tri-nucleotide acid number. L1:ata, L2:tat, L3:ata, L4:tat, L5:ata.2. (L1,L3) =2, (L1,L5) =4, (L3,L5) =2, (L2,L4) =2. So the sample data is 2,4,2,2.3. Sample Data average x= (2+4+2+2)/4=2.5.Variance s2=[(2-2.5) (4-2.5) (2-2.5), (2-2.5) 2]/4=0.75.gi

The following switch from Baidu:Recently in preparation for testing, you need to see which machines are mounted SSD hard drives, Google has seen a lot of methods, but all foggy, do not know how to determine. SSD hard disk seems to use the SCSI interface, so according to the name of the drive letter is not to be judged. The last group of Eric God told LSSCSI Tools, try it, very simple, the display is also very direct, share a bit. Nonsense not much to say, direct and result as follows:[[Email pro

. Since the two-order F and the symmetric matrix are one by one correspondence, it is necessary to prove that the corresponding symmetric matrix positive definite is proved by the two-type positive definite, and the other is to prove that the symmetric matrix is a positive definite matrix, and only the two-order corresponding to it is positive definite two-time type. Example 2 . Set a matrix, if R (a) =n, then aTa is a positive definite matrix. becau
