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,1: single-user mode,2: Multi-

Problem description: there are now n ordered arrays in M groups, such as {1, 2, 3, 4}, {2, 3, 6}, {1, 3, 5, 7 }, select the data smaller than K in these arrays and return this value. Idea: Compare the minimum data selected each time by referring to the process of merging two Arrays

are two ways to implement data sharing between these runnable objects:1, encapsulate the shared data in another object, and then pass the object to each Runnable object. The way each thread operates on shared data is also assigned to that object, which makes it easy to implement mutexes and communications for each operation on that data.2, these runnable objects as the internal classes in a class, the sharing of data as the member variables in this

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; Knowledge

] set the loop variable I, the initial value is 1, traverse to 10.[Cui 8] set sum value to sum + I[Cui 9] step is 2, the default step is 1. Equivalent to the meaning of i+=2! Instead, the default is i++.[Cui] assigns the NS to the item.[Cui]NS is an array that is traversed.[Cui] print each item[Cui] is no different from traversing an array![Cui] because the traversal is a map, so each item is entry type[Cui

Chapter 1: a goal A ship with no sailing targets, the wind in any direction is against the wind 1. Why are you poor? The first point is that you have not set the goal of becoming a rich man. 2.
