Opencv experiences (1)
The second chapter of learning opencv mainly introduces some common and interesting functions and data types, so that students at the beginning are more interested in image processing, although I do not understand the internal experiment of the function and the meaning of some defined constants, I am still very happy after learning Chapter 2. At least I know some basics of image processing, such as contour processing;

can solve the bottleneck of verifying data storage.Because of the high price of the RAID 5 array card, the array is currently used only in large enterprises and is rarely used by internet cafes.RAID 0+1 CombatAfter understanding the various RAID arrays, the following is an example of the setup of Raid 0+1 commonly use

The services provided by the SSL protocol are mainly:1) Authenticate users and servers to ensure that data is sent to the correct client and server;2) Encrypt data to prevent the data from being stolen in the middle; 3) Maintain the integrity of the data and ensure that the data is not changed during transmission. First, what is
Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,

Next we will introduce various RAID technologies
I. RAID 0
The band technology is used to write data in parallel on multiple disks in bytes or bits (the starting offset of each disk is the same, and the subsequent segments of a certain number of bytes, i/O read/write performance can be improved, but it does not have data redundancy like raid1. Once the hard disk fails, it will be done.
